Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding, and in particular to a port grinding device for ball screw processing. Background Technology
[0002] A grinding device is a type of equipment used for surface treatment. It removes surface roughness or oxides by contacting abrasive particles with the workpiece, thereby improving surface smoothness. It is commonly used for the fine processing of materials such as metals, wood, and plastics.
[0003] When grinding the end of a ball screw, the ball screw is placed on a support on the worktable. It is then moved by a drive roller to the grinding roller, where its end is ground. When the ball screw is long, the side furthest from the grinding roller is suspended and easily moves downwards due to gravity. This causes the ball screw on the grinding roller side to tilt, thus affecting the grinding effect on the end of the ball screw. Utility Model Content
[0004] The technical problem this invention aims to solve is that when the ball screw is long, the side furthest from the grinding roller is suspended in the air and is easily affected by gravity, causing the ball screw on the side of the grinding roller to tilt up, thus affecting the grinding effect at the ball screw end.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a ball screw processing end grinding device, including a worktable and a fixed component. A moving roller is provided on one side of the worktable, a grinding roller is provided on one side of the worktable, a support is provided on one side of the worktable, and a limiting device is provided on one side of the support by means of the fixed component. The limiting device limits the ball screw through the limiting roller.
[0006] The effect achieved by the above components is as follows: when grinding the end of the ball screw, the ball screw is placed on the support of the worktable, and the limiting device fixed by the fixing component limits the ball screw. Then the ball screw is moved by the drive roller to the grinding roller, and then the end is ground by the grinding roller.
[0007] Preferably, the limiting device includes a placement frame, a first bolt, a placement plate, a round rod, and a limiting roller. The first bolt moves inside the placement frame and drives the placement plate to move. The limiting roller is set on the side of the placement plate near the support via the round rod. The limiting roller is moved by the first bolt to the upper end of the ball screw for limiting.
[0008] The effect achieved by the above components is as follows: After the ball screw is placed on the bracket, the first bolt is rotated, causing the first bolt to rotate inside the placement bracket. Then, one end of the first bolt rotates on the upper part of the placement plate, driving the placement plate closer to the bracket. Then, the round rod connected to the placement plate rotates, driving the limiting roller fixed on the round rod to reach the upper end of the ball screw on the bracket surface. When the ball screw moves, it drives the round rod inside the limiting roller to rotate inside the placement plate, thus preventing the angle between the ball screw and the bracket from changing and avoiding the situation where one end of the ball screw tilts up. By using the limiting device, the ball screw on the bracket can be limited, preventing the side of the ball screw close to the grinding roller from tilting up and affecting the grinding of the ball screw, thereby improving the use effect of the grinding device.
[0009] Preferably, an operating block is provided on one side of the first bolt, and the operating block raises the dimension of one side of the first bolt.
[0010] The effect achieved by the above components is to increase the contact area between the operator and the first bolt by fixing the operating block on one side of the first bolt, making the first bolt easier to rotate.
[0011] Preferably, bearings are provided at the connection points between the two ends of the round rod and the placement plate, and the bearings reduce the friction between the round rod and the placement plate.
[0012] The effect achieved by the above components is as follows: by fixing the bearing at the connection between the round rod and the placement plate, the friction at the connection between the two is reduced, and then the round rod can rotate more easily inside the placement plate, thereby improving the performance of the limit roller.
[0013] Preferably, a stabilizing component is provided on one side of the placement plate. The stabilizing component includes a stabilizing rod and a through hole opened on the placement frame. The stabilizing rod on one side of the placement plate moves in the through hole on one side of the placement frame to limit the movement trajectory of the placement plate.
[0014] The effect achieved by the above components is that when the placement plate moves, the stabilizing rod fixed on one side of the placement plate will move in the through hole on one side of the placement frame, thereby restricting the movement trajectory of the placement plate and making the placement plate move more stably.
[0015] Preferably, the fixing component includes a square tube, a second bolt, and a threaded hole in the placement frame. The square tube is disposed on one side of the bracket, and the second bolt passes through the square tube and the threaded hole in the placement frame to fix the placement frame in position.
[0016] The effect achieved by the above components is as follows: When using the limiting device, insert the side of the placement rack with the threaded hole into the square tube fixed on the bracket, then rotate the second bolt so that the second bolt passes through the square tube and the threaded hole on the placement rack, and then is threadedly fixed to the placement rack to complete the fixing of the placement rack to one side of the bracket. By using the fixing components, the limiting device can be quickly fixed to one side of the limiting device, which makes it convenient for operators to use the limiting device in the future.
[0017] Preferably, a nut is inserted into one side of the second bolt, and the nut fixes the position of the second bolt.
[0018] The effect achieved by the above components is as follows: after the second bolt is used to fix the placement frame, the nut is rotated so that the nut thread is inserted into one side of the second bolt and abuts against the square tube to fix it, thereby completing the position fixation of the second bolt and improving the use effect of the second bolt.
[0019] Preferably, a trapezoidal block is provided on the side of the placement rack near the threaded hole, and the trapezoidal block reduces the size of one side of the placement rack.
[0020] The effect achieved by the above components is that by fixing the trapezoidal block to one side of the placement rack, the size of one side of the placement rack is reduced, making it easier to insert the square tube into the placement rack.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] By using a limiting device, the ball screw on the bracket can be limited to prevent the side of the ball screw near the grinding roller from tilting up and affecting the grinding of the ball screw, thereby improving the performance of the grinding device.
[0023] By using a fixing component, the limiting device can be quickly fixed to one side, making it easier for operators to use the limiting device later. Attached Figure Description

[0032] Figures 1 to 4 The device shown is an end-grinding apparatus for ball screw processing, comprising a worktable 1 and a fixing assembly 6. A moving roller 2 and a grinding roller 3 are provided on one side of the worktable 1, and a support 4 is provided on one side of the worktable 1. A limiting device 5 is provided on one side of the support 4 via the fixing assembly 6. The limiting device 5 limits the ball screw via a limiting roller 55. When grinding the end of the ball screw, the ball screw is placed on the support 4 of the worktable 1, and the limiting device 5, fixedly installed by the fixing assembly 6, limits the ball screw. Then, the ball screw is moved by the driving roller to the grinding roller 3, where it undergoes end-grinding.
[0033] Figures 1 to 4The limiting device 5 shown includes a placement frame 51, a first bolt 52, a placement plate 53, a round rod 54, and a limiting roller 55. The first bolt 52 moves inside the placement frame 51 and drives the placement plate 53 to move. The limiting roller 55 is set on the side of the placement plate 53 near the bracket 4 through the round rod 54. The limiting roller 55 is moved by the first bolt 52 to the upper end of the ball screw for limiting. After the ball screw is placed on the bracket 4, the first bolt 52 is rotated, causing the first bolt 52 to rotate inside the placement frame 51. Then, one end of the first bolt 52 rotates on the upper end of the placement plate 53, causing the placement plate 53 to move closer to the bracket 4. Then, the round rod 54 rotatably connected to the placement plate 53 drives the limiting roller 55 fixed on the round rod 54 to reach the upper end of the ball screw on the surface of the bracket 4. When the ball screw moves, it drives the round rod 54 inside the limiting roller 55 to rotate inside the placement plate 53, thus preventing the angle between the ball screw and the bracket 4 from changing and avoiding the situation where one end of the ball screw tilts up. By using the limiting device 5, the ball screw on the bracket 4 can be limited, preventing the side of the ball screw close to the grinding roller 3 from tilting up and affecting the grinding of the ball screw, thereby improving the use effect of the grinding device.
[0034] Figures 1 to 4 An operating block 56 is provided on one side of the first bolt 52, which raises the dimension of one side of the first bolt 52. By fixing the operating block 56 to one side of the first bolt 52, the contact area between the operator and one side of the first bolt 52 is increased, making the first bolt 52 easier to rotate. Bearings 57 are provided at the connection points between the round rod 54 and the placement plate 53 at both ends. The bearings 57 reduce the friction between the round rod 54 and the placement plate 53. By fixing the bearings 57 at the connection points of the round rod 54 and the placement plate 53, the friction at the connection point is reduced, making it easier for the round rod 54 to rotate inside the placement plate 53, thereby improving the performance of the limiting roller 55.
[0035] Figures 1 to 4 A stabilizing component 58 is provided on one side of the placement plate 53. The stabilizing component 58 includes a stabilizing rod 581 and a through hole 582 formed on the placement frame 51. The stabilizing rod 581 on one side of the placement plate 53 moves within the through hole 582 on the side of the placement frame 51 to limit the movement trajectory of the placement plate 53. When the placement plate 53 moves, the stabilizing rod 581 fixed on one side of the placement plate 53 moves within the through hole 582 on the side of the placement frame 51, thereby limiting the movement trajectory of the placement plate 53 and enabling more stable movement of the placement plate 53.
[0036] Figures 1 to 4The fixing component 6 shown includes a square tube 61, a second bolt 62, and a threaded hole 63 on the placement frame 51. The square tube 61 is located on one side of the bracket 4. The second bolt 62 passes through the square tube 61 and the threaded hole 63 on the placement frame 51 to fix the position of the placement frame 51. When using the limiting device 5, the side of the placement frame 51 with the threaded hole 63 is inserted into the square tube 61 fixed on the bracket 4. Then, the second bolt 62 is rotated so that it passes through the square tube 61 and the threaded hole 63 on the placement frame 51, and is then threadedly fixed to the placement frame 51 to complete the fixation of the placement frame 51 on one side of the bracket 4. By using the fixing component 6, the limiting device 5 can be quickly fixed to one side, which facilitates the subsequent use of the limiting device 5 by the operator.
[0037] Figures 1 to 4 A nut 64 is inserted into one side of the second bolt 62, fixing its position. After fixing the placement bracket 51 with the second bolt 62, the nut 64 is rotated so that its thread is inserted into one side of the second bolt 62 and abuts against the square tube 61, thus fixing the second bolt 62 in place and improving its performance. A trapezoidal block 65 is provided on the side of the placement bracket 51 near the threaded hole 63, reducing the size of one side of the placement bracket 51. By fixing the trapezoidal block 65 to one side of the placement bracket 51, the size of one side of the placement bracket 51 is reduced, making it easier to insert the square tube 61 into the placement bracket 51.
[0038] Working principle: When grinding the end of the ball screw, the ball screw is placed on the bracket 4 of the worktable 1, and the limiting device 5 fixed by the fixing component 6 limits the ball screw. Then the ball screw is moved by the drive roller to the grinding roller 3, and then the end is ground by the grinding roller 3. After the ball screw is placed on the bracket 4, the first bolt 52 is rotated, causing the first bolt 52 to rotate inside the placement frame 51. Then, one end of the first bolt 52 rotates on the upper end of the placement plate 53, causing the placement plate 53 to move closer to the bracket 4. Then, the round rod 54 rotatably connected to the placement plate 53 drives the limiting roller 55 fixed on the round rod 54 to reach the upper end of the ball screw on the surface of the bracket 4. When the ball screw moves, it drives the round rod 54 inside the limiting roller 55 to rotate inside the placement plate 53, thus preventing the angle between the ball screw and the bracket 4 from changing and avoiding the situation where one end of the ball screw tilts up. By using the limiting device 5, the ball screw on the bracket 4 can be limited, preventing the side of the ball screw close to the grinding roller 3 from tilting up and affecting the grinding of the ball screw, thereby improving the use effect of the grinding device.
[0039] When using the limiting device 5, insert the side of the placement frame 51 with the threaded hole 63 into the square tube 61 fixed on the bracket 4, then rotate the second bolt 62 so that the second bolt passes through the square tube 61 and the threaded hole 63 on the placement frame 51, and then threadedly fixes it to the placement frame 51 to fix the position of the placement frame 51 on one side of the bracket 4. Then rotate the nut 64 so that the nut 64 is threaded into the side of the second bolt 62 and abuts against the square tube 61 to fix the position of the second bolt 62. By using the fixing component 6, the limiting device 5 can be quickly fixed to one side of the limiting device 5, which makes it convenient for the operator to use the limiting device 5 in the future.
