[0002] To meet product functional requirements, the DCT transmission assembly design must ensure a compact structure and light weight. The front housing is designed with an irregular shape and complex structure. After the transmission front housing is produced, a material removal shank operation is required. This necessitates the use of a clamp to hold and fix the transmission front housing. Chinese Patent No. CN202323356105.4 provides a transmission front housing material removal shank clamp, including a rotating plate. Hydraulic cylinders are mounted on both sides of the upper surface of the rotating plate. A hydraulic telescopic rod is mounted at the top of each hydraulic cylinder, and a clamping mechanism is mounted at the top of the hydraulic telescopic rod. A first connecting shaft is installed in a bearing at the center of the rotating plate surface. A transmission front housing placement plate is mounted at the other end of the first connecting shaft. A driven gear is mounted on the outer wall of the rotating plate, meshing with a driving gear. The driving gear is mounted on the output shaft of a first reduction motor, which is mounted on one side of the upper surface of the housing. This utility model facilitates the fixing and clamping of different positions on the front housing of the gearbox by the operator, thereby making it convenient for the operator to remove the material handles at different positions on the front housing of the gearbox. It is easy to operate and use, and has strong practicality.

[0003] Based on the above, the inventors have discovered the following problems: the above device can facilitate the worker to fix and clamp the front housing of the transmission at different positions, thereby facilitating the worker to remove the material handle at different positions of the front housing of the transmission. However, it still requires a power mechanism such as a hydraulic cylinder to drive it, which wastes power resources and cannot adapt well to the outer diameter of the front housing of the transmission.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 The present invention provides a technical solution as follows: Example: In this embodiment, a transmission front housing outer circle adaptive positioning clamping mechanism includes an operation box 1. The lower end of the operation box 1 is provided with a base 2. The upper end of the operation box 1 is provided with a lifting cavity 10. A pair of moving holes 13 are provided on both sides of the lifting cavity 10 and on the operation box 1. The lower end of the lifting cavity 10 and the moving holes 13 and located inside the operation box 1 are provided with a movable cavity. A transmission component is provided in the movable cavity. A moving part 7 is provided in the lifting cavity 10. The upper end of the moving part 7 is provided with a placement platform 3. The lower end of the moving part 7 is provided with a lifting component. The lower end of the lifting component is connected to the upper end of the transmission component. A clamping component is provided in the moving holes 13.

[0017] The lifting assembly includes a rotating shaft 8, a threaded groove 11 inside the moving part 7, a spiral block 12 on the outside of the rotating shaft 8, the threaded groove 11 and the spiral block 12 being adapted to each other, and a return spring 9 being movably provided at the upper end of the rotating shaft 8, with the upper end of the return spring 9 being movably provided at the top of the moving part 7. By placing the front housing of the transmission on the upper end of the placement platform 3 and applying vertical upward pressure to the front housing, the weight of the front housing plus the applied force causes the moving part 7 to descend within the lifting chamber 10. Through the cooperation of the threaded groove 11 and the helical block 12, the rotating shaft 8 can be driven to rotate, which in turn drives the gear 15 to rotate in the same direction, thereby making the transmission assembly work and driving a pair of clamps 4 to clamp the front housing of the transmission. In this way, due to the design of the return spring 9, when the device is not subjected to external force, the placement platform 3 and the pair of clamps 4 return to their initial state, thus preparing for the next clamping.

[0018] The clamping assembly includes a movable plate 5, the movable hole 13 is provided with the movable plate 5, the upper end of the movable plate 5 is provided with a clamp 4, a pair of clamps 4 are symmetrically arranged about the center of the placement platform 3, and the lower end of the movable plate 5 extends into the movable cavity and is provided with a limiting block 14. The rotation of gear 15 can drive a pair of racks 17 to move relative to each other, thereby driving a pair of moving plates 5 to move in the same direction, and driving the clamp 4 to move toward the front housing of the transmission at the upper end of the placement platform 3, thereby achieving the effect of clamping the front housing of the transmission.

[0019] The transmission assembly includes a gear 15 and a rack 17. A rack 17 is provided on the lower end of the movable plate 5 and on a portion of its side located within the movable cavity. A pair of racks 17 are symmetrically arranged about the center of the rotating shaft 8. A gear 15 is provided at the lower end of the rotating shaft 8. Each gear 15 meshes with a pair of racks 17. The lower end of the gear 15 is movably connected to the upper end of the base 2, and a locking assembly is provided on the side of the gear 15. By engaging the clasp 20 with the gear 15, the rotation of the gear 15 can be limited, thereby limiting the movement of the moving plate 5. This allows a pair of clamps 4 to continuously clamp the front housing of the transmission. When it is necessary to release the engagement between the clasp 20 and the gear 15, the handle 6 can be turned, causing the connecting rod 16 and the clasp 20 to move in the same direction, thereby releasing the restriction on the rotation of the gear 15. Furthermore, through the design of the coil spring, the clasp 20 can automatically engage the gear 15 when no external force is applied to the handle 6.

[0020] The engaging assembly includes a connecting rod 16 and a connecting shaft 19. The connecting shaft 19 is located on the side of the gear 15 and inside the movable cavity. A locking tooth 20 is sleeved on the connecting shaft 19 and engages with the gear 15. A coil spring is provided between the locking tooth 20 and the connecting shaft 19. The connecting rod 16 is located at the upper end of the locking tooth 20 and on the connecting shaft 19. The connecting rod 16 extends out of the operating box 1 and is provided with a handle 6. The design of the limiting rod 18, the limiting block 14, and the limiting groove allows the rack 17 and the moving plate 5 to move more smoothly and stably.

[0021] The rack 17 is provided with a limiting rod 18 at its lower end, and the base 2 is provided with a limiting groove at its upper end that is adapted to the limiting rod 18 and the limiting block 14. By designing the outer side of the movable part 7 as a polygon and adapting the outer side of the movable part 7 to the lifting cavity 10, the rotation of the movable part 7 within the lifting cavity 10 can be limited, so that the movable part 7 can only move vertically within the lifting cavity 10.

[0022] The outer side of the movable component 7 is polygonal in shape, and the outer side of the movable component 7 is adapted to the lifting cavity 10; The design of the clamp 4 with a rubber pad can prevent the clamp 4 from scratching the surface of the front housing of the transmission and can increase the friction between the clamp 4 and the surface of the front housing of the transmission.

[0023] The clamp 4 has a rubber pad on the side facing the placement platform 3.

[0024] Working principle: In use, the front housing of the transmission is placed on the upper end of the placement platform 3, and a vertical upward pressure is applied to the front housing. At the same time, the handle 6 is turned, which drives the connecting rod 16 and the chuck 20 to move in the same direction, releasing the restriction effect on the rotation of the gear 15. Thus, the weight of the front housing of the transmission, plus the applied force, causes the moving part 7 to descend in the lifting chamber 10. Through the cooperation of the threaded groove 11 and the spiral block 12, the rotating shaft 8 can be driven to rotate, which in turn drives the gear 15 to rotate in the same direction. The rotation of the gear 15 can drive a pair of racks 17 to move relative to each other, which in turn drives a pair of moving plates 5 to move in the same direction, and drives the clamp 4 to move toward the front housing of the transmission on the upper end of the placement platform 3, thereby achieving the effect of clamping the front housing of the transmission. In particular, through the design of the return spring 9, when the device is not subjected to external force, the placement platform 3 and the pair of clamps 4 return to their initial state, thus preparing for the next clamping.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
