[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 4 The utility model provides an embodiment: a press for bearing processing, comprising a base 1, a clamping mechanism 2 is arranged in the base 1, a bracket 3 is fixedly connected to the top wall of the base 1, a mounting block 14 is arranged in the middle of the bottom wall of the bracket 3, an insert block 5 is slidably connected in the mounting block 14, an extrusion block 8 is rotatably connected to the middle of the front wall of the mounting block 14, a knob 7 is fixedly connected to the front wall of the extrusion block 8, push plates 9 are abutted on both sides of the extrusion block 8, both sides of the front wall of the mounting block 14 are fixedly connected to the limit plates 11, and the two push plates 9 are fixedly connected to the sides away from each other A connecting plate 10 is connected, and the ends of the two connecting plates 10 away from the push plate 9 penetrate the limit plate 11 and are fixedly connected to the plug plate 6. The close ends of the two plug plates 6 penetrate the inner side walls of the mounting block 14 and are clamped inside the plug block 5. The far sides of the two push plates 9 are fixedly connected to one end of the spring three 13, and the other ends of the two spring three 13 are fixedly connected to the limit plate 11; the far sides of the two push plates 9 are fixedly connected to the guide rods 12, and the far ends of the two guide rods 12 penetrate the limit plate 11; the lower sides of the close ends of the two plug plates 6 are provided with inclined surfaces;

[0031] Specifically, by turning the knob 7, the connected extrusion block 8 can be driven to rotate. When the extrusion block 8 rotates, the push plates 9 can be pushed away from each other, thereby driving the connected connecting plates 10 to move away from each other. The fixed plugging plate 6 can be driven to be pulled out from the plugging block 5 through the connecting plate 10, thereby canceling the limit of the plugging plate 6 on the plugging block 5. Then, the plugging block 5 connected to the pressure plate can be pulled out from the mounting block 14 for replacement. When installation is required, it is only necessary to directly insert the plugging block 5 into the mounting block 14 and make contact with the plugging plate 6. Since the plugging plate 6 is provided with an inclined The two push plates 9 are pushed away from each other by the inclined surface. When the two push plates 9 are away from each other, the connecting plate 10 drives the push plates 9 to move away from each other. When the push plates 9 move, the spring three 13 is squeezed. Therefore, after the squeezing block 8 is released, the push plate 9 can be reset under the action of the spring three 13 and the plug plate 6 can be inserted into the plug block 5 for fixation, thereby achieving the effect of facilitating the replacement of the pressure plate. At the same time, under the action of the guide rod 12, the stability of the movement of the push plate 9 can be guaranteed, and the spring three 13 can be prevented from bending after being compressed.

[0032] Reference Figure 1 , Figure 3 and Figure 4 The clamping mechanism 2 includes a rotating rod 201, which is rotatably connected to the middle of the front wall of the base 1. The rear end of the rotating rod 201 penetrates the inner front wall of the base 1 and is fixedly connected to a bevel gear 1 211. Both sides of the bevel gear 1 211 are meshed with bevel gears 212. The two bevel gears 212 are fixedly connected to the far ends of the two threaded rods 208. The outer circumferences of the two threaded rods 208 are threadedly connected to the moving plates 203. The front and rear sides of the two moving plates 203 are rotatably connected to the rotating shafts 206. The plurality of rotating shafts 20 6 is fixedly connected with a clamping plate 205 in the middle, and the upper and lower walls of the multiple clamping plates 205 are fixedly connected with one end of a spring 207, and the other ends of the multiple springs 207 are fixedly connected to the inner wall of the movable plate 203; the two threaded rods 208 are rotatably connected with the support plates 213 at the close ends, and the front and rear ends of the two support plates 213 are fixedly connected to the inner wall of the base 1; the inner wall of the base 1 is fixedly connected with the limit rod 202, and one end of the limit rod 202 passes through the movable plate 203 and is fixedly connected to the other inner side wall of the base 1;

[0033] Specifically, the bevel gear 1 211 can be driven to rotate by rotating the rotary rod 201. When the bevel gear 1 211 rotates, the meshing bevel gear 212 can be driven to rotate. The bevel gear 212 can drive the fixed threaded rod 208 to rotate. At the same time, the threaded rod 208 and the bevel gear 212 can be limited by the support plate 213 to ensure the stability of their rotation. When the threaded rod 208 rotates, the movable plate 203 can be driven to move. Since the movable plate 203 also passes through the limit rod 202 Therefore, under the action of the limiting rod 202, the movable plate 203 can be limited to prevent the movable plate 203 from rotating, so that the movable plate 203 will move when the threaded rod 208 rotates, and then the two movable plates 203 can be driven to approach each other. When the movable plates 203 approach each other, they will contact the bearing to be processed through the clamping plate 205, and then under the action of the spring 207, the clamping plate 205 can clamp the bearing, thereby achieving the effect of centering and clamping bearings of different specifications.

[0034] Reference Figure 1 , Figure 3 and Figure 4 , a hydraulic cylinder 4 is fixedly connected to the middle of the top wall of the bracket 3, and the output end of the hydraulic cylinder 4 passes through the bottom wall of the bracket 3 and is fixedly connected to the mounting block 14; a connecting rod 204 passes through the middle of the two movable plates 203, and the two connecting rods 204 are fixedly connected to the clamping blocks 209 at the close ends, and the two clamping blocks 209 are fixedly connected to the springs 210 at the far ends, and the two springs 210 are fixedly connected to the movable plates 203 at the far ends;

[0035] Specifically, by providing a hydraulic cylinder 4, the mounting block 14 can be driven to move downward and the connected upper pressure plate can be driven to move downward to process the bearing to be processed; by providing a clamping block 209, the bearing can be clamped and positioned under the action of the clamping block 209 and the spring 210 when the two movable plates 203 are close to each other, thereby further ensuring the stability of the clamping.

[0036] Working principle: In actual use, by rotating the extrusion block 8, the push plates 9 can be driven to move away from each other, thereby driving the connected connecting plates 10 to move away from each other, and the fixed plug plate 6 can be driven to be pulled out from the plug block 5 through the connecting plate 10, and then the plug block 5 connected to the pressure plate can be pulled out from the mounting block 14 for replacement. When installation is required, it is only necessary to rotate the extrusion block 8 again and insert the plug block 5 into the mounting block 14. Since the push plates 9 will squeeze the spring three 13 when they move away from each other, the push plate 9 can be reset under the action of the spring three 13 after releasing the extrusion block 8. The insert plate 6 is inserted into the insert block 5 for fixation, thereby achieving the effect of facilitating the replacement of the pressure plate; in addition, by rotating the rotary rod 201, the bevel gear 1 211 can be driven to rotate, thereby driving the bevel gear 2 212 and the threaded rod 208 to rotate, and then the two movable plates 203 can be driven to approach each other. When the movable plates 203 approach each other, they will contact the bearing to be processed through the clamping plate 205, and then under the action of the spring 1 207, the clamping plate 205 can clamp the bearing, thereby achieving the effect of centering and clamping bearings of different specifications.
