[0002] In mechanical and construction engineering, rollers are used for equipment installation or engineering construction. In order to ensure the smoothness of the roller surface, the roller surface is always polished.

[0003] However, since the outer surface of the roller is cylindrical, it is difficult to guarantee the grinding effect when workers directly hold the grinding machine to grind the surface. Uneven grinding of the outer arc surface of the roller is likely to occur, and the actual operation is also difficult, affecting the grinding efficiency. To solve the above problems, we propose an adjustable roller surface grinding frame. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This adjustable roller surface grinding frame, by setting a clamping mechanism, allows the position of the moving plate in the clamping mechanism on the base to be adjusted to meet the clamping and fixing requirements of rollers of different lengths and specifications. After the position of the roller to be ground is restricted by the clamping mechanism, it is convenient for the user to use the grinding mechanism to grind the surface of the roller.

A rotary motor is also fixedly mounted on the outer side of the fixed plate 32. 31, and the output shaft of the rotary motor 31 can be fixedly connected to the disc-shaped positioning shaft 34 on the fixed plate 32; the ends of the second screw 418 adjacent to the U-shaped rod 416 and the ends of the first screw 35 adjacent to the moving plate 33 are provided with expansion plates, which can increase the contact area, prevent excessive pressure due to small contact area, and avoid damage to the contact structure. The end face of the roller body 2 to be ground is provided with a keyway for insertion into the disc-shaped positioning shaft 34, so that the roller body 2 to be ground can be spliced ​​with the disc-shaped positioning shaft 34, thereby using the disc-shaped positioning shaft 34 to drive the roller body 2 to be ground to rotate, thereby improving the grinding efficiency.

[0024] The grinding mechanism 4 includes a U-shaped frame 42 slidably connected to the base 1 and a protrusion 45 fixedly installed on the top surface of the base 1. A guide rod 43 and a first protective cover 44 are fixedly installed on the inner side of the U-shaped frame 42, and a drive motor 41 is fixedly installed on the outer side of the U-shaped frame 42. A slide block 411 is slidably connected to both the guide rod 43 and the first protective cover 44. A connecting seat 410 is fixedly installed on the lower surface of the slide block 411, and a grinding motor 49 is fixedly installed on the connecting seat 410. A grinding wheel 48 is fixedly installed at the end of the output shaft of the grinding motor 49. The U-shaped frame 42 also... A main lead screw 412 is rotatably connected to the slide block 411, and the main lead screw 412 is fixedly connected to the output shaft of the drive motor 41. A main embedded nut 413 is fixedly installed on the side wall of the inner cavity of the slide block 411, and the main embedded nut 413 can be threadedly connected to the main lead screw 412. A second protective cover 47 is fixedly installed on the inner side of the boss 45, and a U-shaped rod 416 is fixedly installed on the outer side of the boss 45.

A secondary embedded nut 413 is fixedly installed on the side wall of the inner cavity of the U-shaped frame 42. 15. The secondary embedded nut 415 is threadedly connected to the secondary lead screw 414. A clamping plate 417 is slidably mounted on the U-shaped rod 416. A second screw 418 is also threadedly connected to the U-shaped rod 416. The end of the second screw 418 can contact the clamping plate 417. A rubber anti-slip pad is provided on the side of the clamping plate 417 adjacent to the turntable 46. The main lead screw 412 is located in the cavity inside the first protective cover 44, and a gap is provided between the main lead screw 412 and the first protective cover 44 for the main embedded nut 413 to pass through.

[0025] Working principle: A disc-shaped positioning shaft 34 is rotatably mounted on the movable plate 33 of the fixed plate 32. A rotary motor 31, whose output shaft is fixedly connected to the disc-shaped positioning shaft 34, is also fixed to the side of the fixed plate 32, which is fixed to the base 1. When clamping the roller body 2 to be ground, the roller body 2 is first sleeved onto the disc-shaped positioning shaft 34. Then, the first screw 35, which is threadedly connected to the threaded seat 36, is rotated to limit the sliding range of the movable plate 33, thereby tightening the first screw 35. The fixed plate 32 and the moving plate 33 cooperate to clamp and fix the roller body 2 to be ground; then the turntable 46 drives the auxiliary lead screw 414 to rotate on the boss 45. The auxiliary embedded nut 415 fixed to the inner wall of the U-shaped frame 42 is threadedly connected to the auxiliary lead screw 414. The U-shaped frame 42 is also slidably connected to the second protective cover 47 fixed on the boss 45. Therefore, when the auxiliary lead screw 414 rotates, it can drive the entire U-shaped frame 42 to slide on the base 1 until the grinding wheel 48 and the roller body 2 to be ground are in contact. Contact is made, and then the second screw 418 is tightened, causing the clamping plate 417 to slide on the U-shaped rod 416, thereby clamping the turntable 46, restricting the rotation of the turntable 46, and locking the position of the auxiliary lead screw 414 and even the U-shaped frame 42; then the drive motor 41 and the grinding motor 49 are started, and the main lead screw 412, which is fixedly connected to the output shaft of the drive motor 41, rotates synchronously, and the slide 411 has a main embedded nut 413 that is threadedly connected to the main lead screw 412. The slide 411 is also fixed to the U-shaped frame 416. The guide rod 43 on the frame 42 is slidably connected to the first protective cover 44. When the main screw 412 rotates, it can drive the slide 411, the connecting seat 410 on the slide 411, the grinding motor 49 on the connecting seat 410, and the grinding wheel 48 on the output shaft of the grinding motor 49 to slide. Thus, the grinding wheel 48 can slide back and forth while rotating. In conjunction with starting the rotary motor 31, the fixed plate 32 drives the roller body 2 to be ground to rotate, thereby achieving the purpose of quickly grinding the outer surface of the roller body 2.
