Description

Technical Field

[0002] Rolls are the main tools used on rolling mills for the plastic deformation of metals. They have smooth cylindrical or grooved surfaces. Roll grinding is a type of surface modification technology that changes the physical properties of the material surface through friction to obtain the desired surface roughness of the roll. With the development of industrial technology, grinding equipment used in roll production has also been continuously evolving to meet the needs of more efficient and precise processing.

[0003] Existing grinding equipment for roll production typically uses simple clamps or bolts for fixing, and then moves grinding blocks or grinding wheels in a fixed direction to grind the roll surface.

The grinding disc 17 is rotatably connected to the end of the outer wall of the threaded rod 4. The grinding disc 17 is used to clamp the grinding block 20 and provide a position for easy installation and disassembly. Since the existing grinding block 20 is usually fixed with bolts, it is necessary to repeatedly tighten the bolts for disassembly and installation, which greatly reduces the grinding efficiency.

[0036] Reference Figures 4-6 The limiting assembly includes a rotating shaft 21, which extends the second gear 16. The outer wall of the rotating shaft 21 has a directional groove for engaging with the directional block on the inner wall of the limiting frame 23 to maintain its directional and stable movement. The end of the outer wall of the rotating shaft 21 is fixedly connected to the center of the inner wall of the second gear 16. The top of the outer wall of the rotating shaft 21 is elastically connected to the limiting frame 23 via a limiting spring 22. The inner wall of the limiting frame 23 has a directional block for engaging with the directional groove on the outer wall of the rotating shaft 21, allowing it to maintain directional movement while simultaneously driving the rotating shaft 21 to move accordingly. A rocker arm is provided at the end of the outer wall for manual rotation. The bottom of the outer wall of the limiting frame 23 is fixedly connected to a limiting block 24, which has two sets, upper and lower, for engaging with the limiting groove 25 to fix the rotation of the limiting frame 23. Angle, a limiting groove 25 is opened on the outer left side of the processing platform 1. Several sets of limiting grooves 25 are provided for multiple locking limiting blocks 24 to change the tilt angle of the support rod 5 and the follower rod 9. The outer wall of the rotating shaft 21 is slidably connected to the inner left side of the processing platform 1. One end of the limiting spring 22 is fixedly connected to the top of the outer wall of the rotating shaft 21, and the other end of the limiting spring 22 is fixedly connected to the top of the inner wall of the limiting frame 23.

The inner wall of the limiting frame 23 is slidably connected to the outer wall of the rotating shaft 21, and the bottom of the outer wall of the limiting block 24 is locked on the inner wall of the limiting groove 25.

[0037] Working principle: When loading and unloading the roll, manually pulling the limit frame 23 causes the limit block 24 to disengage from the limit groove 25, releasing the limit. Then, rotating the limit frame 23 drives the rotating shaft 21 to rotate, which in turn drives the gear 26 to rotate. The gear 26 then drives the gear 15 to rotate, which in turn drives the support rod 5 to tilt outward. Simultaneously, the support rod 5 drives the transmission shaft 8 to rotate, which in turn drives the follower rod 9 to tilt outward, thus causing the roll to tilt to one side of the ground. Finally, manually loosening the chuck 1 7 and chuck 2... 11. Loosen and remove the roller. During installation, manually pull the fixing rod 13 to disengage it from the fixing groove 14 to release the limit. Then, manually move the extension shaft 10 backward to drive the chuck 2 11 backward, thereby achieving the effect of adapting to rollers of different lengths. Then, manually move the roller to the chuck 1 7 and chuck 2 11 to clamp and fix the roller. Then, similarly, rotate and lift the roller to fit the grinding block 20. Then, manually push the limiting frame 23 inward to drive the limiting block 24 to engage with the corresponding limiting groove 25, thereby improving grinding efficiency and reducing the cost of using manual machinery.

[0038] When it is necessary to replace the worn-out grinding block 20, the limit is released by manually pulling the plug rod 19 away from the inner wall of the grinding block 20. Then, the grinding block 20 is manually removed for replacement. After releasing the plug rod 19, the return spring 18 will cause the plug rod 19 to spring back to the inner wall of the grinding block 20 and lock in place, thus achieving quick replacement of the grinding block 20. Then, the motor 6 is turned on to drive the roller to rotate. At the same time, the grinding disc 17 is moved forward by manually rotating the threaded rod 4. The grinding disc 17 moves the grinding block 20 forward to release the roller surface. Then, the grinding base 3 is moved back and forth laterally by the slide rail 2, thereby performing grinding operations on the roller surface, achieving automatic grinding effect and improving grinding efficiency.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
