Abstract
Description
Technical Field
[0001] This utility model relates to the field of bushing grinding technology, and in particular to a bushing outer circle grinding device. Background Technology
[0002] Bushings are fittings used on the outside of mechanical parts to achieve functions such as sealing and wear protection. During bushing production, their outer rings need to be ground. Chinese Patent CN222327709U discloses a bushing outer ring grinding device, relating to the field of bushing processing technology. It includes a worktable, a support column at the top of the worktable, a support plate at the right end of the first support column, a first cylinder at the top of the support plate, and the output end of the first cylinder connected to a positioning component. A second support column is located at the top of the worktable, a first motor at the left end of the second support column, and the output end of the first motor connected to a fixing component. A second motor is located at the rear end of the second support column, and the output end of the second motor connected to a threaded screw. A slide is located on the surface of the threaded screw, a second cylinder is located at the top of the slide, and the output end of the second cylinder connected to a slider. A third support column is located at the top of the slider, two rotating shafts at the left end of the third support column, and a bracket at the front end of the third support column. Two rotating shafts are located at the left end of the bracket. Multiple rotating shafts are connected by a grinding belt. This solution improves the bushing's fixing effect and enhances processing efficiency and accuracy through an adjustment mechanism.
[0003] The aforementioned patent uses positioning and fixing components to fix the bushing during use. However, the outer diameters of the positioning and fixing components are fixed. To prevent the bushing from becoming eccentric during installation, the inner diameter of the bushing must be the same as the outer diameters of the positioning and fixing components. This limits the patent to grinding bushings with the same inner diameter, resulting in a narrow application range. In actual production, different models of bushings have different inner diameters, making the patent unsuitable for grinding different models of bushings. Therefore, there is an urgent need to develop a bushing outer diameter grinding device that is easy to adjust and can easily grind bushings with different inner and outer diameters to overcome the shortcomings in current applications and meet current needs. Utility Model Content
[0004] The purpose of this invention is to provide a bushing outer diameter grinding device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A bushing outer diameter grinding device includes a worktable, an adjustable clamping mechanism, a rotating mechanism, a transverse mechanism, and a grinding mechanism. The rotating mechanism is mounted on the worktable to drive the adjustable clamping mechanism to rotate. The adjustable clamping mechanism includes a cylinder, clamping rods, rings, springs, adjusting rods, and screws. The cylinder is fixed to the rotating mechanism. There are three clamping rods, which are evenly distributed in a circle around the central axis of the cylinder. Each clamping rod has a ring fixed on it. The rings are elastically connected to the inner wall of the cylinder by springs. The adjusting rod is located at the center of the cylinder. The outer surface of the adjusting rod is truncated cone-shaped, and the diameter of the adjusting rod gradually increases from top to bottom. The screw is connected to the cylinder by threads, and the upper end of the screw is fixed to the adjusting rod. The transverse mechanism is mounted on the worktable, and the grinding mechanism is mounted on top of the transverse mechanism. The grinding mechanism is located to the right of the adjustable clamping mechanism.
[0007] Preferably, a rotating handle is fixed to the lower end of the screw.
[0008] Preferably, the rotating mechanism includes: a first motor, a first gear, a second gear, a support shaft, and a turntable. The first motor is fixed on the worktable, and a first gear is fixed on the output shaft of the first motor. A second gear is provided on one side of the first gear to mesh with it. The second gear is fixed on the support shaft. The support shaft is rotatably connected to the worktable, and a turntable is fixed at the upper end of the support shaft.
[0009] Preferably, the transverse movement mechanism includes a bracket, sliders, a slide rail, and an electric telescopic rod.

[0011] The beneficial effects of this utility model are as follows: When using this bushing outer circle grinding device, the bushing is fitted onto the outside of the cylinder. Then, the handle is turned by hand to move the screw upwards, which in turn moves the adjusting rod upwards. The adjusting rod pushes the three clamping rods outwards, ensuring they are firmly pressed against the inner wall of the bushing, thus fixing bushings of different inner diameters. Next, an electric telescopic rod moves the support, which in turn moves the grinding mechanism, causing the grinding roller to contact the outer ring of the bushing for grinding. After adjustment, the first and second motors are started. The second motor drives the grinding roller to rotate and grind the outer ring of the bushing. The first motor drives the first gear, second gear, support shaft, and turntable to rotate, which in turn drives the adjustable clamping mechanism to rotate, which in turn drives the bushing to rotate, ensuring the outer ring of the bushing is thoroughly ground. In summary, this utility model is easy to adjust and convenient for grinding bushings of different inner and outer diameters. Attached Figure Description

In use, the bushing is put on the outside of the cylinder 201, and then the rotating handle 2061 is turned by hand to move the screw 206 upward. The screw 206 moves the adjusting rod 205 upward, and the adjusting rod 205 pushes the three clamping rods 202 outward, so that the three clamping rods 202 are tightly pressed against the inner wall of the bushing, so as to fix bushings with different inner diameters. The transverse movement mechanism 4 is installed on the worktable 1, and the grinding mechanism 5 is installed on the top of the transverse movement mechanism 4. The grinding mechanism 5 is located to the right of the adjustable clamping mechanism 2.

The first gear 302 is fixed on the output shaft of the first motor 301. A second gear 303 is provided on one side of the first gear 302 and meshes with it. The second gear 303 is fixed on the support shaft 304. The support shaft 304 is rotatably connected to the worktable 1. The turntable 305 is fixed at the upper end of the support shaft 304. The cylinder 201 is fixed on the turntable 305. In use, the first motor 301 drives the first gear 302, the second gear 303, the support shaft 304, and the turntable 305 to rotate. The turntable 305 drives the adjustable clamping mechanism 2 to rotate.
[0024] The transverse mechanism 4 includes: a bracket 401, a slider 402, a slide rail 403, and an electric telescopic rod 404. Two sliders 402 are fixed to the bottom of the bracket 401.

[0026] The workbench 1 is equipped with a motor controller 6 and a telescopic rod controller 7.
[0027] Working principle: In use, the bushing outer diameter grinding device involves placing the bushing onto the outside of the cylinder 201, then manually turning the rotary handle 2061 to move the screw 206 upwards. The screw 206 then moves the adjusting rod 205 upwards, which in turn pushes the three clamping rods 202 outwards, ensuring they are firmly pressed against the inner wall of the bushing. This secures bushings of different inner diameters. Then, the electric telescopic rod 404 moves the bracket 401, which in turn moves the grinding mechanism 5, allowing the grinding process to proceed smoothly. The grinding roller 502 is attached to the outer ring of the bushing to grind bushings of different outer diameters. After adjustment, the first motor 301 and the second motor 501 are started. The second motor 501 drives the grinding roller 502 to rotate and grind the outer ring of the bushing. The first motor 301 drives the first gear 302, the second gear 303, the support shaft 304 and the turntable 305 to rotate. The turntable 305 drives the adjustable clamping mechanism 2 to rotate. The adjustable clamping mechanism 2 drives the bushing to rotate, so that the outer ring of the bushing is thoroughly ground.
