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.

[0024] like Figures 1 to 6 As shown, the present invention provides a bushing press, including a base 1, a support frame 2 fixedly connected to the top of the base 1, a piston cylinder 3 fixedly connected to the top of the support frame 2, and the output end of the piston cylinder 3 extending into the interior of the support frame 2 and fixedly connected to a pressure plate 4.

A fixing frame 6 located on top of the magnet block 5 is movably connected inside the base 1. The top of the fixing frame 6 extends to the outside of the base 1. A mounting frame 7 located at the bottom of the magnet block 5 is movably connected inside the pressure plate 4. The bottom of the mounting frame 7 extends to the outside of the pressure plate 4. Iron plates 8 are fixedly connected to the bottom of the fixing frame 6 and the top of the mounting frame 7. Filled rubber 9 is fixedly connected to the inner side of the fixing frame 6 and the surface of the mounting frame 7. A guiding mechanism is provided on the top of the pressure plate 4, and a detection mechanism is provided on the surface of the base 1.

[0026] refer to Figure 6 The guiding mechanism includes guide rods 10 fixedly connected to the top of the pressure plate 4 and located on both sides of the piston cylinder 3. The top of the guide rods 10 extends to the outside of the support frame 2 and is fixedly connected to a baffle 11. A protective mechanism is provided on the surface of the guide rods 10.

[0027] As a technical optimization of this utility model, by setting guide rod 10 and baffle 11, the pressure plate 4 is guided and limited when it moves up and down, so as to avoid the pressure plate 4 tilting or shifting, thereby affecting the press machine's pressing of the bushing.

[0028] refer to Figure 6 The protective mechanism includes an auxiliary frame 12 fixedly connected to the top of the support frame 2 and located outside the guide rod 10. The bottom of the auxiliary frame 12 extends into the interior of the support frame 2. A ball bearing 13 is movably connected inside the auxiliary frame 12, and the inner side of the ball bearing 13 is movably connected to the surface of the guide rod 10.

[0029] As a technical optimization of this utility model, by setting the auxiliary frame 12 and the ball bearing 13, the guide rod 10 is protected to avoid friction between the guide rod 10 and the support frame 2, which would cause the guide rod 10 to wear and reduce its service life.

[0030] refer to Figure 3 The testing mechanism includes a storage slot 14 located on the top of the base 1 and on the front of the mounting bracket 6, and an electronic level 15 is fixedly connected inside the storage slot 14.

[0031] As a technical optimization of this utility model, by setting up a storage slot 14 and an electronic level 15, the press can be tested, making it convenient for workers to judge whether the press is in a horizontal state, and avoiding the press being affected by the press pressing the bushing due to the press being in a tilted state.

[0032] refer to Figure 3 The top of the base 1 is fixedly connected to a hook and loop fastener 16 located outside the storage slot 14. The top of the hook and loop fastener 16 is fixedly connected to a hook and loop rough surface 17. The top of the hook and loop rough surface 17 is fixedly connected to an anti-scratch film 18.

[0033] As a technical optimization of this utility model, the electronic level 15 is protected by the anti-scratch film 18 to prevent the electronic level 15 from being scratched by friction from external objects. The hook side 16 and the loop side 17 of the hook and loop fasteners make it convenient for workers to replace the damaged anti-scratch film 18.

[0034] refer to Figure 5 The base 1 has a buffer rubber 19 fixedly connected inside. The top and bottom of the buffer rubber 19 are movably connected to the bottom of the fixing frame 6 and the top of the magnet block 5, respectively. The pressure plate 4 has a waterproof membrane 20 located at the bottom of the magnet block 5 fixedly connected inside. The bottom of the waterproof membrane 20 is movably connected to the top of the mounting frame 7.

[0035] As a technical optimization of this utility model, the magnet block 5 is protected by setting buffer rubber 19 and waterproof membrane 20 to prevent the magnet block 5 from being damaged by rust due to contact with water.

[0036] The working principle and usage process of this utility model are as follows: In use, first, the fixing frame 6 and mounting frame 7, which match the size of the bushing and the liner, are placed on the base 1 and the pressure plate 4 respectively. The iron sheet 8 is attracted by the magnet 5, thereby connecting the fixing frame 6 and the mounting frame 7 to the base 1 and the pressure plate 4. Then, the bushing is inserted into the fixing frame 6, and the liner is placed on the mounting frame 7. Then, the piston cylinder 3 is started. The piston cylinder 3 drives the pressure plate 4, the mounting frame 7 and the liner to move downward through the output end, so that the liner and the bushing are pressed together. After the bushing is pressed together, the piston cylinder 3 drives the pressure plate 4 and the mounting frame 7 to move upward through the output end, so that the mounting frame 7 is away from the fixing frame 6. Finally, the worker removes the pressed bushing from the fixing frame 6. Since the magnet 5 is a strong magnet with a strong magnetic force, the fixing frame 6 and the mounting frame 7 will not separate from the base 1 and the pressure plate 4 because the bushing and the liner are separated from the fixing frame 6 and the mounting frame 7.

[0037] In summary, this bushing press, by setting up a fixed frame 6 and a mounting frame 7, allows workers to simply insert the bushing and liner into the fixed frame 6 or onto the mounting frame 7. The use of filler rubber 9 increases the friction between the bushing and liner and the fixed frame 6 and mounting frame 7, preventing the bushing and liner from falling off. Furthermore, the use of magnets 5 and iron plates 8 facilitates easy replacement of the fixed frame 6 and mounting frame 7 according to the size of the bushing and liner. Since the connection between the bushing and liner and the fixed frame 6 and mounting frame 7 can be completed in just one step, the working efficiency of the press is improved.
