Description

Technical Field

[0001] This utility model relates to the field of roller processing technology, and in particular to a positioning and fixing plate for roller sheet production. Background Technology

[0002] Roller blades, also known as drums, rollers, or wheels, are rotating metal cylinders in machinery. They are usually made from metal tubes through processes such as rough turning, finishing, shaft assembly, grinding, and dynamic balancing. Depending on their application, they can be divided into drive rollers and driven rollers.

[0003] In the process of clamping and positioning rollers, the existing roller production equipment has insufficient stability, and the rollers are prone to movement, which causes the position of their center line to deviate, resulting in uneven wall thickness, reduced processing accuracy, and shortened service life. To address these issues, we propose a positioning and fixing plate for roller sheet production. Utility Model Content

[0004] The purpose of this invention is to provide a positioning and fixing plate for roller sheet production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioning and fixing disc for roller sheet production includes a disc shell. A dual-output shaft reduction motor is fixedly connected to the inner wall of the disc shell. Threaded rods are fixedly connected to both the upper and lower output ends of the dual-output shaft reduction motor. Threaded blocks are threaded onto the outer surface of each threaded rod. An extension block is fixedly connected to the front of each threaded block. L-shaped connecting plates are fixedly connected to the front of both extension blocks. Cylinders are fixedly connected to the outer surfaces of both L-shaped connecting plates. The output end of each cylinder passes through each L-shaped connecting plate and extends to the side of the two L-shaped connecting plates that are close to each other. A first clamping block is fixedly connected to the output end of each cylinder. A second clamping block is fixedly connected to the front of each L-shaped connecting plate.

[0007] In a further embodiment, a sliding groove is fixedly connected to the front side of each L-shaped connecting plate, and a slider is slidably connected to the inner sidewall of each sliding groove.

[0008] In a further embodiment, the front of each slider is connected to the back of each first clamping block.

[0009] In a further embodiment, two support seats are fixedly connected to the inner wall of the disc shell, and the inner ring of each support seat is connected to the outer surface of each threaded rod. A control device is provided on the back of the disc shell.

[0010] In a further embodiment, four sliding plates are fixedly connected to the inner sidewall of the disc shell, and the outer surfaces of every two sliding plates are slidably connected to the outer surface of each threaded block.

[0011] In a further embodiment, a plurality of suction cups are fixedly connected to the front of the disc shell, and a multi-port pipe is fixedly connected to the outer surface of each suction cup. One end of the multi-port pipe is fixedly connected to a valve, and the valve is fixedly connected to an air compressor through an air pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device connects the roller to two second clamping blocks. A dual-output shaft reduction motor drives the threaded rod to rotate, and the threaded blocks move up and down with the rotation of the threaded rod. This causes the threaded blocks to drive the second clamping blocks to clamp and position the inner wall of the roller, keeping the roller on the same center line. A cylinder drives the first clamping block to move, clamping and fixing the outer surface of the roller. By clamping both the inner and outer walls of the roller simultaneously, the stability of the clamping and positioning is increased, making it less prone to movement. Attached Figure Description

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.

[0022] Please see Figure 1-4In this utility model, a positioning and fixing disc for roller sheet production includes a disc shell 1. A dual-output shaft reduction motor 2 is fixedly connected to the inner side wall of the disc shell 1. Threaded rods 3 are fixedly connected to both the upper and lower output ends of the dual-output shaft reduction motor 2. Threaded blocks 4 are threadedly connected to the outer surface of each threaded rod 3. An extension block 5 is fixedly connected to the front of each threaded block 4. An L-shaped connecting plate 6 is fixedly connected to the front of each of the two extension blocks 5. Cylinders 7 are fixedly connected to the outer surfaces of the two L-shaped connecting plates 6. The output end of each cylinder 7 passes through each L-shaped connecting plate 6. Plate 6 extends to the side of two L-shaped connecting plates 6 that are close to each other. The output end of each cylinder 7 is fixedly connected to a first clamping block 8, and the front side of each L-shaped connecting plate 6 is fixedly connected to a second clamping block 9. The threaded rod 3 is driven to rotate by the dual-output shaft reduction motor 2, so that the threaded block 4 drives the L-shaped connecting plate 6 and the second clamping block 9 to move, thereby clamping the inner wall of the roller and fixing the roller on the same center line. The first clamping block 8 is driven to move by the cylinder 7, so that the first clamping block 8 clamps the outer surface of the roller. The double clamping from the inside and outside improves the stability during positioning.

[0023] Each L-shaped connecting plate 6 has a slide groove 10 fixedly connected to its front side. Each slide groove 10 has a slider 11 slidably connected to its inner side wall. The front side of each slider 11 is connected to the back side of each first clamping block 8. Two support seats 12 are fixedly connected to the inner side wall of the disc shell 1. The inner ring of each support seat 12 is connected to the outer surface of each threaded rod 3. A control device 18 is provided on the back side of the disc shell 1. Through the cooperation of the slide groove 10 and the slider 11, the first clamping block 8 can only move up and down, preventing the first clamping block 8 from tilting.

[0024] Four sliding plates 13 are fixedly connected to the inner side wall of the disc shell 1. The outer surfaces of every two sliding plates 13 are slidably connected to the outer surface of each threaded block 4. Multiple suction cups 14 are fixedly connected to the front of the disc shell 1. A multi-port pipe 15 is fixedly connected to the outer surface of each suction cup 14. A valve 16 is fixedly connected to one end of the multi-port pipe 15. The valve 16 is fixedly connected to an air compressor 17 through an air pipe. Through the cooperation of the suction cups 14, the multi-port pipe 15 and the air compressor 17, the closed roller can be held and made more stable.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, the roller is fitted onto the two second clamping blocks 9. The dual-output shaft reduction motor 2 is turned on to drive the threaded rod 3 to rotate. Under the restriction of the sliding plate 13, the threaded block 4 moves up and down with the rotation of the threaded rod 3, thereby causing the threaded block 4 to drive the second clamping blocks 9 to clamp the inner wall of the roller, fixing the roller on the same horizontal line, thus completing the clamping and positioning of the roller. The cylinder 7 is turned on to drive the first clamping block 8 to move, so that the first clamping block 8 clamps and fixes the outer surface of the roller. When the roller is solid or the roller is in a closed state, the second clamping block 9 is controlled to clamp the outer surface of the roller, and the valve 16 is opened so that the suction cup 14 sucks the roller tightly to prevent the roller from moving.
