Description

Technical Field

[0001] This utility model relates to the field of paper machine stabilizing roll processing technology, specifically a drill bit replacement device for drilling holes in paper machine stabilizing rolls. Background Technology

[0002] In the field of papermaking machinery, stabilizing rolls are key components that ensure stable tension and paper feed during paper production. During their manufacturing and maintenance, drilling is often required to meet installation or structural needs. In existing technologies, drilling of stabilizing rolls typically involves using a general-purpose drilling machine or simple tooling for clamping and drilling.

[0003] A drilling device for industrial roller processing, disclosed in CN217452211U, is described. This device comprises a processing groove, a lead screw, a guide block, and a support base plate. A second motor drives the support base plate to move horizontally, facilitating drilling at different locations on the roller surface. An air pump, an air guide pipe, a waste collection box, and a waste hole are included to blow away waste generated during drilling, allowing the waste to enter the waste collection box through the waste hole at the bottom of the processing groove, thus facilitating waste removal.

[0004] This drilling device for industrial roller processing moves the clamping plate by setting a threaded push rod, so that the frame plate can push and clamp the industrial roller on the left and right sides. However, when the device clamps the roller from the left and right sides, the contact area is small, which makes the roller easy to slip during drilling and affects the drilling accuracy. Therefore, it needs to be improved. Utility Model Content

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1-5 This utility model provides a technical solution: a drill bit replacement device for drilling holes for a paper machine stabilizing roller, including a base 1, a fixed platform 2 fixedly connected to the top of the base 1, a clamping mechanism 3 provided inside the fixed platform 2, a punching mechanism 5 provided at the back of the top of the fixed platform 2, and a stabilizing roller body 4 provided inside the clamping mechanism 3.

[0029] The clamping mechanism 3 includes a protective frame 32, which is fixedly connected to the bottom of the fixed platform 2. A drive motor 31 is fixedly connected to the right side of the protective frame 32, and a bidirectional threaded rod 33 is fixedly connected to the left side of the drive motor 31. The bidirectional threaded rod 33 is rotatably connected to the inner side of the protective frame 32. A threaded plate 34 is threadedly connected to the outer side of the bidirectional threaded rod 33. A linkage frame 35 is fixedly connected to the top of the threaded plate 34. A vertical plate 38 is fixedly connected to the top of the linkage frame 35. A first hydraulic cylinder 37 is fixedly connected to the outer side of the vertical plate 38. A connecting plate 39 is fixedly connected to the inner side of the first hydraulic cylinder 37. A slide rod 36 is fixedly connected to the outer side of the connecting plate 39. A V-shaped clamping plate 301 is fixedly connected to the inner side of the connecting plate 39.

[0030] Furthermore, the fixed platform 2 has sliding grooves on its front and rear sides that correspond to the movement trajectory of the linkage frame 35, and the linkage frame 35 is slidably connected inside the sliding grooves. The sliding grooves can limit the movement of the linkage frame 35, making the linkage frame 35 more stable during movement.

[0031] Furthermore, there are two slide rods 36. The two slide rods 36 are fixedly connected to the top and bottom of the outer side of the connecting plate 39, and the two slide rods 36 are slidably connected to the inner side of the vertical plate 38. The slide rods 36 can limit the movement of the connecting plate 39, making the connecting plate 39 more stable during movement.

[0032] Furthermore, the V-shaped clamp 301 is disposed around the periphery of the stabilizing roller body 4, and the inner side of the V-shaped clamp 301 is in close contact with the outer wall of the stabilizing roller body 4. The V-shaped clamp 301 can clamp and fix the stabilizing roller body 4, making the stabilizing roller body 4 more stable during the drilling process.

[0033] Example 2

[0034] Please see Figure 1-5 Furthermore, based on Embodiment 1, the drilling mechanism 5 further includes a support frame 51, which is fixedly connected to the top back end of the base 1. A second hydraulic cylinder 53 is fixedly connected to the top of the support frame 51, and a lifting plate 55 is fixedly connected to the bottom of the second hydraulic cylinder 53. A limit rod 52 is fixedly connected to the inner back end of the lifting plate 55. A servo motor 54 is fixedly connected to the top of the lifting plate 55, and a rotating shaft 56 is fixedly connected to the bottom of the servo motor 54. A fixed plate 58 is fixedly connected to the bottom of the rotating shaft 56. A support member 57 is fixedly connected to the top periphery of the fixed plate 58, and a connecting plate 59 is fixedly connected to the bottom of the fixed plate 58. A drilling motor 502 is fixedly connected to the inner side of the connecting plate 59, and a drilling rod 501 is fixedly connected to the bottom of the drilling motor 502. The drilling rod 501 is rotatably connected to the inner side of the connecting plate 59.

[0035] Furthermore, a moving groove corresponding to the movement trajectory of the limiting rod 52 is provided on the inner side of the support frame 51, and the limiting rod 52 is slidably connected inside the moving groove. Through the moving groove, the limiting rod 52 can slide inside the support frame 51, making the lifting plate 55 more stable during the lifting process.

[0036] Furthermore, a circular groove corresponding to the movement trajectory of the support member 57 is provided on the inner side of the lifting plate 55, and the support member 57 is slidably connected inside the circular groove. Through the circular groove, the support member 57 can slide on the inner side of the lifting plate 55, so that when the servo motor 54 operates, it can drive the fixed plate 58 to rotate through the rotating shaft 56, making the fixed plate 58 more stable during rotation.

[0037] In actual operation, when this device is used and drilling is required on the paper machine stabilizing roller body 4, the operator places the paper machine stabilizing roller body 4 between two V-shaped clamping plates 301 using external equipment. According to the length of the stabilizing roller body 4, the drive motor 31 is turned on, causing the drive motor 31 to drive the bidirectional threaded rod 33 to rotate. The bidirectional threaded rod 33 drives the linkage frame 35 and the vertical plate 38 to move through the threaded plate 34. The vertical plate 38 can drive the connecting plate 39 and the V-shaped clamping plate 301 to move through the first hydraulic cylinder 37. When the V-shaped clamping plate 301 moves to the appropriate position, the switches of the four first hydraulic cylinders 37 are turned on at the same time, causing the first hydraulic cylinders 37 to push the connecting plate 39 and the V-shaped clamping plate 301 to move. This causes the inner wall of the V-shaped clamping plate 301 to fit against the outer wall of the stabilizing roller body 4, allowing the V-shaped clamping plate 301 to clamp and fix the stabilizing roller body 4.

[0038] To determine the required hole size, turn on the servo motor 54 switch, causing the servo motor 54 to drive the fixed disk 58 to rotate via the rotating shaft 56. The fixed disk 58 then drives the drilling motor 502 to rotate via the connecting disk 59. The drilling motor 502 then drives the drilling rod 501 to rotate, bringing the drilling rod 501 to the top of the stabilizing roller body 4. Turn on the drilling motor 502 switch, causing it to drive the drilling rod 501 to rotate. Turn on the second hydraulic cylinder 53 switch, causing the second hydraulic cylinder 53 to push the lifting plate 55 and the limit rod 52 downwards. This causes the lifting plate 55 to drive the servo motor 502 to rotate. The servo motor 54, rotating shaft 56, support 57, and fixed plate 58 move downwards, causing the fixed plate 58 to drive the connecting plate 59, drilling motor 502, and drilling rod 501 to rotate, enabling the drilling rod 501 to drill holes in the stabilizing roller body 4. When it is necessary to replace the drilling bit, the servo motor 54 drives the rotating shaft 56 and fixed plate 58 to rotate, causing the fixed plate 58 to drive the drilling motor 502 and drilling rod 501 to rotate through the connecting plate 59. This device makes it convenient for workers to replace the drilling rod 501 and can meet the drilling needs of different paper machine stabilizing roller bodies 4.
