The actuating assembly includes a cylinder 112, a connecting rod 113, and an actuating rod 114. This solution facilitates quick replacement of wheel hub clamps during wheel hub dust cover assembly.

[0022] In this embodiment, the base 101 is fixed by positioning pins and bolts.

[0023] The support base 102 is fixed to the base 101, and there are four of them. The positioning plate 103 is fixed to the top of the support base 102. The top of the positioning plate 103 is provided with a mounting groove, and T-shaped grooves are provided on both sides of the mounting groove. The T-shaped part on the reference plate 104 can slide directly into the T-shaped groove. The reference plate 104 can be pre-installed at the bottom of different wheel hub fixing clamps. The limiting plate 105 is integrally formed with the insert block 106 and is set on the front side of the reference plate 104. 106 is slidably connected to the positioning plate 103. The pin 107 is slidably connected to the positioning plate 103 and the pin 106 respectively, and passes through the positioning plate 103 and the pin 106 respectively. The T-shaped threaded sleeve 108 is detachably connected to the positioning plate 103 and is located on the rear side of the positioning plate 103. The adjusting device is located on one side of the T-shaped threaded sleeve 108. The locking device is located on the side of the positioning plate 103 near the pin 107 and is located on the bottom side of the pin 107. The support base 102 has perforated discs at its bottom and top, facilitating connection to the base 101 and the positioning plate 103 respectively via bolts. The positioning plate 103 has a non-through mounting groove running from front to back, with T-shaped grooves on both sides to facilitate the placement of the T-shaped portions on both sides of the reference plate 104. The reference plate 104 has multiple threaded holes and pin holes, allowing for the pre-installation of different wheel hub clamps onto the reference plate 104 to form an integrated replacement structure. The insertion blocks 106 are integrally mounted on both sides of the limiting plate 105. The insert 106 has a vertically arranged circular hole, and the positioning plate 103 has rectangular sliding grooves on both sides from front to back to facilitate the setting of the insert 106. The pin 107 can be directly inserted vertically into the positioning plate 103 and the insert 106, and will not interfere with the installation and removal of the pin 107 after the wheel hub clamp is installed. The T-shaped threaded sleeve 108 is fixed by countersunk bolts. The adjustment device is used for the installation, fixing and adjustment of the reference plate 104 with different front and rear dimensions. The locking device is used to improve the stability of the reference plate 104 after installation.

[0024] Secondly, the adjusting screw 109 is threadedly connected to the T-shaped threaded sleeve 108 and passes through the T-shaped threaded sleeve 108, and its front end can abut against the rear side of the reference plate 104; the mating nut 110 is installed on the adjusting screw 109 and abuts against the T-shaped threaded sleeve 108. The front side of the adjusting screw 109 is a stepped optical shaft, and its external thread end can be directly rotated with the T-shaped threaded sleeve 108. The mating nut 110 can be directly installed on the adjusting screw 109. When fixing the reference plate 104 with different front and rear dimensions, the reference plate 104 is first installed on the positioning plate 103, and then the insert 106 is installed through the limiting plate 105. The left-side pin 107 is further locked by the locking device. Then, the mating nut 110 is loosened, moving away from the T-shaped threaded sleeve 108. Then, the adjusting screw 109 is rotated until its front end abuts against the rear side of the reference plate 104, and the front side of the reference plate 104 abuts against the limiting plate 105, thus fixing the reference plate 104.

[0025] Then, the slide block 111 is fixedly connected to the positioning plate 103 and is located on the bottom left side of the positioning plate 103; the actuating component is disposed on the side of the slide block 111 near the pin 107. The slide block 111 is fixed by a positioning pin and bolt arranged from bottom to top, and is provided with a through sliding hole. The actuating component is used to further lock and limit the left pin 107, while the right pin 107 may not be provided with the locking device.

[0026] Finally, the cylinder 112 is fixedly connected to the positioning plate 103 and is located on the side of the positioning plate 103 near the slide 111; the connecting rod 113 is slidably connected to the slide 111, passes through the slide 111, and is connected to the output end of the cylinder 112; the actuating rod 114 is connected to the connecting rod 113 and can be slidably inserted into the bottom round hole of the pin 107. The cylinder 112 is fixed to the rectangular portion at the bottom of the positioning plate 103 by bolts. Its control box is installed on the front left side of the positioning plate 103. The output end of the cylinder 112 is provided with an external thread end, which is directly connected to the right threaded cavity of the connecting rod 113. The external thread end provided on the right side of the actuating rod 114 is directly connected to the left threaded cavity of the connecting rod 113. A rectangular protrusion is provided below the abutment plate of the pin 107. The rectangular protrusion cooperates with the through rectangular sliding groove on the positioning plate 103. The rectangular protrusion helps to ensure that the through hole of the pin 107 is accurately aligned with the actuating rod 114.

[0027] When using this invention to facilitate quick replacement of wheel hub clamps during wheel hub dust cover assembly, the reference plate 104 can be pre-installed on the bottom of different wheel hub clamps. Then, when replacing different wheel hub clamps, first control the cylinder 112 to retract. The retraction of the cylinder 112 drives the connecting rod 113 and the actuating rod 114 to move to the right, thereby completely disengaging the actuating rod 114 from the left-side pin 107. After removing the two pins 107, remove the limiting plate 105 and the insert block 106. At this point, the wheel hub clamp on the positioning plate 103 can be directly slid forward through the reference plate 104 and removed. Then, directly remove the bottom of the wheel hub clamp to be replaced. The reference plate 104 of the part is slidably mounted on the positioning plate 103 and pushed to the rear. Then, the insert block 106 is inserted and pushed into place by the limiting plate 105. The pin 107 is then installed for limiting. Finally, the locking device is controlled to automatically move to limit the left pin 107, and the installation is completed. In this application, when the wheel hub clamp is disassembled, after the locking device is automatically released, the two pins 107 are removed and the limiting plate 105 and the insert block 106 can be directly removed for direct disassembly. The structure has fewer disassembly bolts and does not require the setting of a positioning pin structure, which is more conducive to convenient disassembly. This also facilitates the quick replacement of the wheel hub clamp when assembling the wheel hub dust cover.
