DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0022] Please refer to Figures 1-3, the present utility model provides a technical solution: a processing fixture for chain track links, including a base 1, with rotating shafts 2 arranged on both sides of the base 1, a processing table 3 arranged on the rotating shafts 2, a top plate 4 arranged on the processing table 3, a support block 5 arranged below the top plate 4, two limit plates 6 arranged on the support block 5 and cooperating with the top plate 4, and an adjusting device 7 arranged between the two limit plates 6. The adjusting device 7 includes a sliding groove 8 and two sliding blocks 9. The sliding groove 8 is designed to be arc-shaped, and the two sliding blocks 9 are connected to the sliding groove 8 through a lead screw 10. The adjusting device 7 further includes a fixing hole 11. One side of the rotating shaft 2 is also connected with a driving device 12. The limit plates 6 are provided with guiding surfaces 13, and the two limit plates 6 and the adjusting device 7 enclose a processing space 14 for the chain track links.

[0023] Specifically, baffles 15 are also arranged on both sides of the processing table 3. By arranging the baffles 15, during the processing process, the chain track links can be stably placed in the processing space 14, avoiding the phenomena of deviation or dislocation caused by vibration or external force interference. The design of the baffles 15 not only enhances the overall structural strength of the processing fixture but also further improves the processing accuracy and safety.

[0024] Specifically, the processing table 3 and the support block 5 are connected through elastic elements, and the surface of the top plate 4 is also provided with an anti-slip layer. Through the above settings, the impact force that may be generated during the processing is effectively buffered, avoiding unnecessary damage to the chain track links caused by the processing table 3. The anti-slip layer on the surface of the top plate 4 further enhances the clamping stability. Even in a processing environment with high-speed rotation or severe vibration, it can ensure that the chain track links will not slip off, ensuring the safety and continuity of the processing process.

[0025] Specifically, the adjusting device 7 further includes a scale indicator 16, and the scale indicator 16 is installed on the side of the sliding groove 8. By arranging the scale indicator 16, the operator can intuitively understand the moving position and adjusting degree of the sliding block 9, thereby realizing precise control of the size of the processing space 14. This design greatly simplifies the adjustment process, improves work efficiency, and reduces processing errors caused by improper adjustment.

[0026] Specifically, a number of mounting holes 17 are also opened on the base 1. By arranging a number of mounting holes 17, the top plate 4 and the support block 5 can be additionally installed according to the requirements of different models of chain track links, and the overall adaptability is better.

[0027] Specifically, shock-absorbing pads 18 are also arranged at the bottom of the base 1. By arranging the shock-absorbing pads 18, during processing, the overall fixture is safer and more stable.

[0028] Specifically, the top plate 4 is snap-connected to the processing table 3. Such a setting makes the top plate 4 convenient for replacement and maintenance. At the same time, the corresponding limit plates 6 and the top plate 4 can be replaced according to the chain track links to form a more suitable processing space 14.

[0029] A specific application embodiment of this embodiment is as follows:

[0030] First, place the chain track link to be processed in the processing space 14 to ensure that it is stably seated between the limiting plates 6. Due to the presence of the two side baffles 15, the chain track link will maintain a stable posture during the processing,

[0031] The operator will precisely adjust the processing space 14 through the adjusting device 7 according to the size and processing requirements of the chain track link. During specific operation, using the scale indicator 16 as a reference, the two sliders 9 slide in the arc-shaped chute 8, thereby driving the limiting plates 6 to move towards the center or both sides until the ideal size of the processing space 14 is reached.

[0032] After the adjustment is completed, start the driving device 12. The rotating shaft 2 drives the processing table 3 and the chain track link thereon to start rotating and adjust to the corresponding angle suitable for processing. The processing table 3 is connected to the support block 5 through an elastic element, which can not only effectively absorb the impact force generated during the processing and protect the chain track link from damage, but also the anti-slip layer on its surface ensures the clamping stability and prevents the chain track link from slipping during high-speed rotation.

[0033] During the processing, when it is necessary to replace the top plate 4 or the limiting plate 6 to adapt to different models of chain track links, the operator can easily snap and remove the top plate 4 from the processing table 3 and install the new top plate 4 and the corresponding limiting plate 6 as needed. This design greatly improves the flexibility and adaptability of the fixture, enabling this device to be widely applied to various processing scenarios of chain track links.

[0034] In addition, the shock-absorbing pad 18 provided at the bottom of the base 1 plays an important role during the processing. It effectively isolates the vibration generated by the processing equipment, ensures the overall stability and safety of the fixture, and at the same time creates a more stable working condition for the processing environment.
