Four-jaw chuck for vertical lathe roughing machine base

Explosion-proof motor vertical lathe roughing machine seat claw chuck Zhang Yi Zhang Mingsheng Jiamusi Motor Co., Ltd., Heilongjiang Jiamusi 154002 principle and characteristics.

1 Introduction The workpieces such as the vertical lathe machining motor base are especially the rough ones in the multiple times. In many cases, the vertical lathe is used to leave the factory. The accessory 1 is called a separate chuck claw, which is fixed and fixed. On the big plate of the car, then, the machine base to be machined is placed on the chuck claws, and the claws are adjusted one by one, and then the ones are clamped one by one to perform the first machining of the car. For the frame of 180 355 or larger, the end face and the inner diameter of the rough end face of the vertical car should be produced in small batches, and the live change is frequent. The position of the single-claw claw must be changed frequently, the operator is labor-intensive, and the auxiliary worker The length of time, the production efficiency is low, the height of the motor center is larger, the weight of the machine base is also larger, and the weight is heavier. There are more than a dozen bases in each class, and the mainframes are frequently hoisted one by one, and the coils are repeatedly found with a chuck claw. It is tightening, and sometimes it is necessary to turn the market to find the right one. The labor intensity is too high, the work efficiency is low, and the quality is difficult to ensure that the labor intensity is reduced and the production efficiency is improved. Improve the processing quality, and gradually improve and create the universal claw chuck and the inner diameter centering claw chuck for the two vertical lathe roughing machine seats.

Claw It simplifies the trouble of replacing the claws of the fashion unloading chucks, reduces the labor intensity of disassembling the chuck jaws, reduces the replacement time and facilitates the operation. This kind of Zhang Yinan was born in 1967; graduated from Harbin Institute of Electrical Engineering, now engaged in motor quality testing.

Explosion-proof motor clamps are difficult to manufacture. General motors can be manufactured by themselves in the range of production varieties. It is not necessary to purchase the access chuck claws of the lathe attachment, the structure and principle of the 21.1 universal claw chuck cast a circular chuck base, and the circumference is symmetrically cast to form a fixed mouth with the vertical disc, which is a clamping chuck. The bolts are used to symmetrically cast the criss-crossing platform to prepare the cross-shaped jaw slides. The iron scraps of the low-profile platform processing frame formed by the cross between the high platforms will be thrown out from here, each slide end The outer or inner side is provided with a screw limit device, and the rotating screw drives the long claw to move back and forth in the slide to clamp the base. When the timing is changed, the independent universal chuck claw is operated, and the screw of each claw is separately adjusted. In order to avoid the slide rail and the lead screw of the iron 1 falling into the claw when the machine base is broken, a chuck cap is arranged on the chuck, and the outer diameter of the chuck cap can be configured according to the size of the processing base. . Two rings are symmetrically arranged on the shoulder platform of the chuck, which is convenient for lifting the chuck 甩 21.2 universal claw chuck. 3. The claws are arranged on a chuck, and the integrity is good, and the lifting and placing device is neat and orderly.

The replacement of the loading and unloading bolts is reduced to four by four bolts of the independent chuck claws.

22 support inner circle centering claw card to describe the universal claw chuck, the chuck has good integrity, and the amount of fastening bolts for the replacement loading and unloading disc is reduced, but it is still a universal chuck for each jaw to be adjusted and corrected. The structure of the steel plate base with uniform wall thickness is too slow, and the operation labor intensity is large. The structure and principle of the 22.1 inner diameter centering claw chuck are divided into two layers of the cross section of the universal claw chuck. The top screw rods are connected in two, the screw end is left threaded, and the other end is right thread. Each pair of jaws is also made into left and right threads, and the center of the screw is positioned at the center of the screw to avoid iron filings. Into the slide, the chuck must also be set on the chuck after the initial installation, fixed on the large plate of the vertical car, adjust the two screws to allow the roots of the claws to hold the ring-shaped ring, the car out of each chuck claw working surface The tooth-shaped groove, after the car is good, remove the claws to face the fire, 2 1 positioning device 3. Machine 4. Dish, 5. Claw 6. Screw æ¡´ inner diameter centering claws work The principle is to twist the root screw so that the long claws at both ends of the screw are the same, move outward at a constant speed, center the base from the screw, and then twist the other wire. The two pairs of jaws respectively center the lower end of the base from the cross direction. After aligning the upper end of the base, tighten the screw to tighten the base. Completing the process of finding the clamping process 22.2 The characteristics of the inner diameter centering claw chuck The screw jaw chuck has better overall performance, and it is more convenient to adjust the silver loading and lifting.

1 The centering of the blank of the machine base is not reasonable enough. The uniformity of the inner and outer diameters of the base blank is uniform and the wall thickness is uniform. The adaptability to the casting machine is poor, but for processing such as 18 marine motors and 515 mines. The steel plate base of the motor has several advantages. Finding the bottom is quick and easy.

3 Concluding remarks The above-mentioned type of lathe roughing machine uses a variety of claw chucks, which have been put into production and application, and can replace the common chucking claws of the original vertical lathe attachment.
