8, the bed is used to fix and support the milling machine parts. The top surface has a horizontal guide for movement of the beam. The front wall has a dovetail vertical guide for the lift up and down. Equipped with the main motor, spindle speed mechanism, spindle, electrical equipment and lubricating oil pump and other components.

9, beams at one end of the beam with a hanger, to support the arbor to reduce the bending and vibration of the arbor. The beam can be moved along the horizontal guide of the bed, and its extension length is adjusted by the length of the arbor.

10, the spindle is used to install the Arbor and drive the cutter to rotate. The spindle is a hollow shaft with a front 7:24 precision tapered bore, which serves to install the cutter handle cone shank.

11, vertical table longitudinal table by the longitudinal screw drive on the turntable guide for vertical movement, to drive the workpiece on the table for longitudinal feed. The T-slot on the table is used to install the fixture or workpiece.

12, horizontal table Horizontal table is located on the horizontal table above the horizontal rail, can drive the vertical table with a horizontal feed.

13, turntable turntable can be vertical table in the horizontal plane to pull a certain angle (positive and negative are 0 ~ 45o), in order to milling spiral groove and so on. Horizontal milling machine with turntable is called horizontal universal milling machine.

14, the lift can drive the entire table along the bed vertical guide up and down to adjust the workpiece and the distance between the milling cutter and vertical feed.

15, base base to support the bed and lift, within the cutting fluid.

2.2 drag

Characteristics of Electric Driving of Universal Milling Machine

Electric drag is a motor as a prime mover to drag the movement of mechanical equipment, a form of drag, also known as electrical drive. As the power is more convenient, 80% of the machine equipment are applied to power drag. The use of electric drag not only can improve the control performance of mechanical equipment, but also improve product quality and labor productivity.

Universal milling machine power drag features are the following:

1, milling milling and reverse milling with two kinds of processing methods, requiring the spindle motor can reverse, because the positive and negative operation is not frequent, so there is a bed underneath the electrical box on the combination switch to change the power phase sequence to achieve.

2, because the spindle drive system is equipped with to avoid the shock of the inertia wheel, so the spindle motor using electromagnetic clutch brake to achieve an accurate stop.

3, universal milling machine table requirements before and after, around the upper and lower six directions of the feed movement, so the motor can be reversed, and through the operation of the handle and mechanical clutch to achieve. The rapid movement of the feed is achieved by means of an electromagnet and a mechanical pallet. The rotary motion of the circular table is driven by the feed motor drive mechanism.

4, according to the requirements of processing technology, universal milling machine should have the following electrical interlocking measures:

In order to prevent damage to the tool and milling machine, only the spindle rotation allows the feed movement and feed direction of the rapid movement. In order to reduce the roughness of the machined surface, the spindle can only be stopped or stopped at the same time after the feed is stopped. The use of mechanical control handle and position switch to match the way to achieve the feeding cloud top 6 interlocking. Spindle movement and feed cloud speed using variable speed plate to speed selection, in order to ensure that the gears into a good state of engagement, the two Genting are required to change the speed after the move. When the spindle motor or cooling pump is overloaded, the feed movement must be stopped immediately to avoid damage to the tool and milling machine.

5, requires a cooling system, lighting and various protective measures.

3.2 Machine structure and characteristics

Universal milling machine body, the main drive, feed boxes, lifts, workstations, cantilever, cooling, lubrication and electrical and other components. The main body is installed in the bed, through the right side of the bed cover on the three variable speed handle to adjust the spindle speed; feed box hanging on the right side of the slide , Through the output shaft gear and sliding gear power will be passed to the vertical and horizontal screw; lift and the bed with a dovetail rail with the vertical movement along the bed guide; lift and slide by the rectangular guide with the table and slide The cantilever part has a fixed seat, a ram, a rack, and a fixed base is mounted on the fuselage, and the ram is fitted through a dovetail rail, and the hanger is equipped with a fixed seat, Hanging in the end of the ram; coolant stored in the cavity of the base; lubrication main drive sector using lubricating oil pump forced lubrication, the feed tank with oil-immersed splash lubrication, the rest of the moving parts of the hand pump or oil cups fixed lubrication; Box hidden in the bed, the electrical control operation, respectively, adverbial lift on the left side of the bed or the right side of the bed or supported by the cantilever bracket in the base of the left front, easy to operate.

3.3 Operating procedures

1, before the operation to wear tight protective clothing, cuffs fastening, coat hem can not open, is strictly prohibited to wear gloves, not in the machine to wear the next, to change clothes, or around the body, to prevent the machine twist. Must wear a helmet, braids should be placed in the hat, not wearing skirts, slippers. Wear protective goggles: to prevent iron scrap splash eyes and install the baffle around the machine to isolate it from the operating area.

2, the workpiece before clamping, should be prepared clamping method. When loading blanks, the table should be padded so that it does not damage the workbench.

3, the table should be checked when moving fastening screws should be opened, the table does not move when the tightening screws should be tight.

4, the tool loading and unloading, should keep the cutter part of the cone and cone hole clean, and to clamp firmly. High-speed cutting must wear protective glasses. Workbench is not allowed to stack tools, parts and other objects, pay attention to the distance between the tool and the workpiece to prevent the impact of the accident.

5, before installing the milling cutter should check the tool number, intact, milling cutter as close as possible to the spindle installation, installed after the test. The installation of the workpiece should be firm.

6, the work should be hand feed, and then gradually automatic knife. Running automatically when the knife, pull the hand wheel, pay attention to the limit block is solid, are not allowed to put the head, do not go to the two extremes and crashed screw; use fast travel, to check whether it will collide in advance and so on, So as not to hit the badge, milling cutter broken out of injury. Always check whether the safety spring inside the handle is effective and reliable.

7, the cutting is prohibited to touch the blade and processing parts. Measurement and inspection of the workpiece must be carried out, the cutting is not allowed to adjust the workpiece.

8, before the spindle stops, must first stop the feed. If the cutting depth is large, the retreat should be the first stop, the wheel must be cut off the power supply, the wheel gap should be appropriate, wheel carriage back to be fastened to avoid falling; processing rough when the speed should not be too fast Eat knife and feed.

9, found that the machine is faulty, should immediately stop the inspection and report the construction and security department repair repair. Work should be done to clean up the work and turn off the power.
