[0002] A bearing bush is the part of a sliding bearing that contacts the journal, and its shape is a semi-cylindrical surface in the shape of a tile.

[0003] When the bearing bush is produced and processed, clamping equipment is used to limit the bearing bush. At present, the clamping equipment positions the bearing bush through two oppositely moving limiting plates, and processes the limited bearing bush with a processing tool. Since the existing limiting plates and the clamping equipment are fixedly installed, and the bearing bush has different specifications due to different materials, the fixed connection between the limiting plates and the clamping equipment causes the limiting plates to only limit one specification of the bearing bush, making it difficult for the clamping equipment to limit bearing bushes of different specifications. This not only reduces the adaptability of the clamping equipment, but also cannot guarantee the stability of the bearing bush in the clamping equipment, resulting in displacement or deflection of the bearing bush during processing, thereby affecting the efficiency and level of bearing bush processing. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the clamping equipment in the prior art can only limit one specification of the bearing bush, and to propose a bearing bush clamping device.

A contact plate corresponding to the inner wall of the bearing bush is fixedly installed on the first connecting rod. A pressing plate corresponding to the outer wall of the bearing bush is connected in the cavity through a connecting piece.

[0007] Preferably, the lead screw is horizontally arranged. A guide seat is fixedly installed on the nut, and a limiting groove for limiting the guide seat is formed in the base.

[0019] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Referring to Figures 1-3 , a bearing bush clamping device includes a base 1. A placement groove 2 and a cavity 3 are formed in the base 1 and are in communication with each other. A bracket 4 is fixedly installed on the base 1, and a motor 5 is fixedly installed on the bracket 4. The output end of the motor 5 is fixedly connected to a lead screw 6, and a matching nut 7 is slidably sleeved on the lead screw 6;

[0021] The lead screw 6 is horizontally arranged. A guide seat is fixedly installed on the nut 7, and a limit groove for limiting the guide seat is formed in the base 1. The movement direction of the nut 7 can be limited through the mutual cooperation of the guide seat and the limit groove. A support one 8 is fixedly installed on the nut 7, and a connecting rod one 9 is placed in the support one 8. A contact plate 10 corresponding to the inner wall of the bearing bush is fixedly installed on the connecting rod one 9. When the lead screw 6 rotates driven by the motor 5, the nut 7 drives the support one 8, the connecting rod one 9, and the contact plate 10 to move leftward, so that the contact plate 10 can movably abut against the inner wall of the bearing bush during movement;

[0022] The contact plate 10 and the connecting rod one 9 extend to the side position outside the support one 8, and a locking bolt one detachably connected to the connecting rod one 9 is threadedly connected to the support one 8. By selecting the specification of the contact plate 10 and connecting the support one 8 and the connecting rod one 9 through the locking bolt one, the contact plate 10 can be mutually attached to the inner wall of the bearing bush during movement;

[0023] A pressing plate 16 corresponding to the outer wall of the bearing bush is connected in the cavity 3 through a connecting member;

[0024] The connecting member includes a guide rod 11 fixedly installed in the cavity 3, and symmetrically arranged sliders 12 are slidably sleeved on the guide rod 11. A support two 14 is movably sleeved in the cavity 3, and a connecting rod 13 is connected between the support two 14 and the two sliders 12. The guide rod 11 plays a role in guiding the sliders 12, so that the sliders 12 can stably pull the connecting rod 13 during movement;

[0025] A connecting rod two 15 is placed in the support two 14, and the pressing plate 16 is arranged on the connecting rod two 15. A telescopic rod 17 connected to the slider 12 is fixedly installed in the cavity 3. The guide rod 11 is horizontally arranged. The two ends of the connecting rod 13 are respectively pin-connected to the support two 14 and the slider 12. A locking bolt two detachably connected to the connecting rod two 15 is threadedly connected to the support two 14. By selecting the specification of the pressing plate 16 and connecting the support two 14 and the connecting rod two 15 through the locking bolt two, the pressing plate 16 can abut against and press the bearing bush during movement;

[0026] By selecting the specifications of the abutting plate 10 and the pressing plate 16, the abutting plate 10 and the pressing plate 16 can limit bearing bushes of different specifications, thereby enhancing the adaptability of the clamping device;

[0027] Both the abutting plate 10 and the pressing plate 16 are arc-shaped structures adapted to the bearing bush, and soft gaskets that are movably abutted against the bearing bush are provided on both the abutting plate 10 and the pressing plate 16. By setting the abutting plate 10 and the pressing plate 16 as arc-shaped structures adapted to the bearing bush, the contact area between the abutting plate 10 and the pressing plate 16 and the bearing bush can be increased. By further providing soft gaskets on the abutting plate 10 and the pressing plate 16, the abutting plate 10 and the pressing plate 16 will not damage the bearing bush when clamping the bearing bush, which not only ensures the stability of the bearing bush in the clamping device but also improves the processing efficiency of the bearing bush;

[0028] It should be noted that the specific model specifications of the motor 5 and the telescopic rod 17 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated.

[0029] The functional principle of the present utility model can be described through the following operation method:

[0030] Select the sizes of the abutting plate 10 and the pressing plate 16 according to the specifications of the bearing bush;

[0031] After the abutting plate 10 is selected, extend the connecting rod one 9 equipped with the abutting plate 10 into the support one 8, and use the locking bolt one to connect the support one 8 and the connecting rod one 9;

[0032] After the pressing plate 16 is selected, extend the connecting rod two 15 equipped with the pressing plate 16 into the support two 14, and use the locking bolt two to connect the support two 14 and the connecting rod two 15;

[0033] Vertically place the bearing bush in the placement groove 2, so that the inner wall and the outer wall of the bearing bush face the abutting plate 10 and the pressing plate 16 respectively;

[0034] The output end of the telescopic rod 17 expands and contracts to drive the two sliders 12 to slide towards each other on the guide rod 11. When the slider 12 slides, it pulls the connecting rod 13 to deflect, so that the position difference generated when the connecting rod 13 deflects can press the support two 14, causing the support two 14 to drive the connecting rod two 15 to extend into the placement groove 2 when sliding in the cavity 3. When the connecting rod two 15 moves, it drives the abutting plate 10 and the soft gasket to abut and press the bearing bush, so that the bearing bush gradually approaches and fits with the placement groove 2, and then the telescopic rod 17 is closed;

[0035] The output end of the motor 5 drives the lead screw 6 to rotate, causing the lead screw 6 to drive the nut 7 to move with the guide seat. When the guide seat slides in the limit groove, the nut 7 drives the first support 8 to move leftward. When the first support 8 moves, it drives the first connecting rod 9 and the contact plate 10 to move, causing the contact plate 10 to drive the soft gasket to fit against the inner wall of the bearing bush.

[0036] After the bearing bush is fixed, turn off the motor 5 and machine the positioned bearing bush.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
