Description

Clutch damping spring press-fitting device

Technical Field

The invention belongs to the technical field of clutch assembly.

Background

The friction disc of the clutch is a relatively critical part in the clutch, a damping spring is required to be assembled in the friction disc, the number of the damping springs is different according to different sizes or different damping effects of the friction disc, and the conventional number is eight. The damping spring is generally mounted in a small window in the friction disc, the space is small, the spring is placed in the damping spring, the spring needs to be slightly compressed, and the residual elastic force is enough to perform the damping function of the clutch. The conventional spring installation is a manual device, the manual device needs to compress and clamp the spring firstly and then place the spring in a small window, and after the manual device is released, the spring is arranged in the small window of the friction disc in a slightly-compressed manner. Although this device can solve the problems of installation, it has a relatively low efficiency due to the manual operation, which substantially increases the labor intensity of the operator.

Detailed Description

The bottom of a frame 5 is provided with a universal wheel 4, a bedplate 6 is fixedly arranged on the frame 5, a compression mechanism 1 is arranged on the bedplate 6, a power mechanism 3 is arranged below the compression mechanism, and a control button 2 of the power mechanism 3 is arranged on the outer side of a frame body formed by the frame 5 and the bedplate 6; the frame 5 is only a frame body formed by a plurality of upright posts and transverse posts and plays a role of a mechanism for supporting a bedplate and an upper door, and the universal wheels 4 are conventional technology, so that the whole mechanism can be moved conveniently at any time. The main improvement of the invention lies in that the compression mechanism 1 and the power mechanism 3, the control button 2 is a simple electronic switch, and the control button is a relatively common connecting technology at present as long as the control button can control the work of the air cylinder, and the description is not repeated.

The power mechanism 3: fixed mounting has fixed bolster 9 on platen 6, fixed mounting has cylinder block mount pad 10 on the fixed bolster 9, the cylinder body 27 fixed mounting of cylinder is in cylinder block mount pad 10, the cylinder stopper 11 of cylinder passes cylinder block mount pad 10 front end and shift fork 12 fixed connection, shift fork 12 is connected with the outer end hub connection of pendulum rod 14 through

pendulum shaft

13, 14 inner ends of pendulum rod with lead to 8 bottom fixed connection of axle, lead to the top that axle 8 passed platen 6 and pass through epaxial seat 15 and be connected through the bearing, lead to 8 hypomere of axle and be equipped with logical axle lower seat 7 through the bearing cover outward, lead to axle lower seat 7 fixed mounting on platen 6.

The compression mechanism 1: the upper end of the through shaft 8 is fixedly provided with a fork frame 16, the tail end of a shift lever 17 is clamped by a double fork of the fork frame 16, a sliding groove 23 is formed in the shift lever 17, a sliding shaft 22 penetrates through the double fork of the fork frame 16 and the sliding groove 23 of the shift lever 17, a fixed shaft 24 is fixedly arranged on the rack 6, the shift lever 17 is sleeved on the fixed shaft 24 through a shaft hole, the front end of the shift lever 17 is provided with a shift head 25, the shift head 25 is inserted into a groove at the tail end of a spring pressing seat 21, and the circular part at the front end of the spring pressing seat 21 is arranged in an inner ring of; a friction disc mounting table 19 is fixedly mounted on the stand 6, the friction disc mounting table 19 covers the spring pressing seat 21 and the annular limiting 26, a through groove is formed in the position, corresponding to the spring pressing seat 21, of the friction disc mounting table 19, and a spring shifting clamp 20 is fixedly mounted on the spring pressing seat 21. Since the slide shaft 22 is fixed to the yoke 16 and is rotated about the shift lever 17, there is a possibility that the yoke 16 and the shift lever 17 are locked when the slide shaft 22 is rotated about the yoke 16, the shift lever 17 is provided with the slide groove 23 to solve this problem, so that the slide shaft 22 can move forward and backward in the slide groove 23, and the forward and backward movement of the slide groove 23 is not so large, and if there is a little, the problem of locking when the yoke 16 and the shift lever 17 are rotated in a staggered manner can be solved.

The spring is compressed first and then is smaller than the size of the small window, so that the spring can be placed in the small window conveniently.

The working process of the invention is as follows: the friction disc is firstly placed on a friction disc mounting table 19, a spring shifting block 20 penetrates through a small window on the friction disc 19, the spring shifting block 20 (spring clamp) is in a release state, a damping spring is sequentially placed on the spring clamp, then a control button 2 is opened, a cylinder starts to work, a cylinder plug 11 of the cylinder is ejected, a shifting fork 12 moves forwards, a swing rod 14 connected with a shaft of the shifting fork 12 rotates by taking a through shaft 8 as an axis and simultaneously drives the through shaft 8 to rotate, a fork frame 16 is driven to swing by taking the through shaft 8 as an axis when the through shaft 8 rotates, the fork frame 16 drives a shifting rod 17 to rotate by taking a fixed shaft 24 as an axis, so that the other end of the shifting rod 17 can shift a spring pressing seat 21 to rotate through a shifting head 25, a spring clamping mechanism (spring clamp) at the top end of the spring pressing seat 21 can compress the spring, the friction disc is lifted after compression, and the spring simultaneously enters the small window of, the air cylinder works in the reverse direction, all the transmission mechanisms work in the reverse direction (can also be understood as reset work), and finally the spring clamp releases the clamping of the spring.

The distance from the fixed shaft 24 to the tail end of the deflector rod 17 is greater than the distance from the fixed shaft 24 to the front end. The change of the distance can ensure that the whole transmission mechanism moves in a small range, namely the spring compression installation process can be completed.

The invention is covered with a swing limit 18 between the fixed shaft 24 and the tail end of the shift lever 17, and the swing limit 18 is fixedly arranged on the rack 6. This prevents the toggle lever 17 from swinging too much.
