Description

Technical Field

[0001] The utility model relates to the technical field of coupling processing, in particular to a clamp for processing couplings. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. It rotates together during the transmission of motion and power and does not disengage under normal circumstances. It is sometimes used as a safety device to prevent the connected parts from being subjected to excessive loads and plays an overload protection role.

[0003] Currently, when processing the circular shaft components of the universal coupling, the universal coupling needs to be clamped and fixed when grinding the top of the circular shaft components. When clamping the circular shaft components, the existing clamp uses a belt with multiple grooves to clamp and fix the circular shaft components. Although this belt can clamp and fix multiple circular shaft components at one time, due to the toughness of the belt itself, it is easy to shift the position when clamping the circular shaft components, which affects the grinding accuracy of the circular shaft components. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies in the above-mentioned background technology and to propose a fixture for machining a coupling.

[0018] Under the action of the processing table, universal coupling, transmission mechanism, clamping mechanism and anti-slip mechanism, the anti-slip mechanism can prevent the universal coupling from sliding vertically and rotationally on the inner wall of the limit opening when the L-shaped slide in the clamping mechanism clamps and fixes the universal coupling, thereby further improving the stability of the device.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-3 The fixture for processing the coupling includes a processing table 1 and multiple universal couplings 2. The multiple universal couplings 2 are arranged on the top of the processing table 1 through a transmission mechanism.

[0026] The transmission mechanism includes two fixed plates 10 fixed on the top of the processing table 1, and multiple transmission rollers 11 rotate between the two fixed plates 10. The adjacent transmission rollers 11 are connected by a connecting chain.

The universal joint 2 is horizontally placed on the multiple transmission rollers 11.

[0027] The processing table 1 is provided with a clamping mechanism on the top, which includes two slide grooves 3. The two slide grooves 3 are opened on the top of the processing table 1 and are located on both sides of the center of the processing table 1. An L-shaped slide plate 4 is slidingly provided in the slide groove 3. A plurality of limit openings 5 are opened at the end of the L-shaped slide plate 4. The distance between two adjacent limit openings 5 on the same side is the same. The shape and position of the limit opening 5 are as follows: Figure 1 As shown, the inner side walls of the two chutes 3 are only rotatably connected to two bidirectional threaded rods 6, the L-shaped slide plate 4 is threadedly sleeved on the two bidirectional threaded rods 6, and the two bidirectional threaded rods 6 are arranged in parallel.

[0028] Two threaded holes that are compatible with the bidirectional threaded rod 6 are provided on the outer wall of the L-shaped skateboard 4. The outer wall of the bidirectional threaded rod 6 and the inner wall of the threaded hole are threadedly connected. The spiral directions of the two threaded holes along the direction of the bidirectional threaded rod 6 are opposite. The two adjacent bidirectional threaded rods 6 are connected by a transmission chain 7. A transmission chain disk that is compatible with the transmission chain 7 is sleeved on the outer wall of the bidirectional threaded rod 6. A servo motor 8 is fixed to the outer wall of the processing table 1. The output shaft of the servo motor 8 is fixedly connected to the end of one of the bidirectional threaded rods 6.

[0029] A starting mechanism is provided in one of the chutes 3 , and the starting mechanism includes a push-type starting button 9 fixed on the inner wall of one of the chutes 3 , and the driving motor 12 and the push-type starting button 9 are electrically connected via a connecting wire.

The rubber plug 15 and the triangular rubber anti-sliding block 16 can prevent the universal coupling 2 from sliding during processing when the L-shaped slide 4 clamps the universal coupling 2.

[0031] The functional principle of this utility model can be explained through the following operation modes:

[0032] 1. Overall Structure and Preparation Stage

[0033] A plurality of universal joints 2 are placed on the transmission roller 11 of the transmission mechanism, waiting for processing operation, and the state of the device is as follows: Figure 1 shown.

[0034] 2. Clamping stage

[0035] Start the servo motor 8 and the output shaft thereof rotates forward. The output shaft of the servo motor 8 will drive the bidirectional threaded rod 6 to rotate forward. The bidirectional threaded rod 6 will drive the two L-shaped slides 4 thereon to move toward the universal coupling 2 together until the limit opening 5 at the end of the L-shaped slide 4 clamps the universal coupling 2. The rubber plug 15 on the inner wall of the limit opening 5 will slide on the inner wall of the limit hole 13, and the spring will contract until the inner wall of the limit opening 5 is tightly fitted on the outer wall of the universal coupling 2, and multiple triangular rubber anti-sliding blocks 16 are fitted on the outer wall of the universal coupling 2, and the servo motor 8 is turned off.

[0036] 3. Processing stage

[0037] The plurality of clamped and fixed universal couplings 2 are processed until the processing is completed and the output shaft of the servo motor 8 is started to reverse.

[0038] 4. Discharging stage

[0039] The output shaft of the servo motor 8 will drive the bidirectional threaded rod 6 to reverse, and the two L-shaped slides 4 on the bidirectional threaded rod 6 will move toward both sides until the L-shaped slide 4 on the left presses the push-type start button 9 to turn off the servo motor 8, so that the push-type start button 9 starts the drive motor 12, and the output shaft of the drive motor 12 drives one of the transmission rollers 11 to rotate, so that the transmission roller 11 drives the universal coupling 2 that has been processed thereon to transmit, until the new universal coupling 2 is located between the two L-shaped slides 4, the output shaft of the servo motor 8 is started to rotate forward, so that the output shaft of the servo motor 8 drives the L-shaped slide 4 to no longer contact the push-type start button 9, thereby turning off the drive motor 12, so that the universal coupling 2 is located between the limit openings 5 of the L-shaped slide 4, and the process of clamping the universal coupling 2 is the same as the clamping stage.
