Description
Technical Field
[0001] This utility model relates to the field of bushing processing technology, specifically to an adjustable bushing positioning device. Background Technology
[0002] Bushings are accessories used on the outside of mechanical parts to achieve functions such as sealing and wear protection. They are mostly made of soft metals, rubber, nylon and non-metallic polymers. In various harsh working environments, bushings withstand vibration, friction and corrosion to protect the wrapped parts. The bushings themselves are easy to replace after damage, with low cost and good economy.
[0003] The existing bushings need to be positioned and fixed during the polishing process. Since the bushings are usually positioned and fixed by clamping the outer wall of the bushing, this fixing method will cause the clamping position to be unable to be effectively ground and polished, thus affecting the polishing effect.
[0004] To address the above problems, this utility model provides an adjustable bushing positioning device. Summary of the Invention
[0005] The purpose of this utility model is to provide an adjustable bushing positioning device, which quickly positions and fixes the inner wall of the bushing by means of two positioning clamping rods, so that the bushing is not obstructed when grinding the outer wall. Then, the outer wall of the bushing is positioned and clamped by the clamping plate. The positioning clamping rods release the positioning and fixing of the bushing, thereby avoiding the positioning clamping rods from affecting the processing of the inner wall of the bushing. It is convenient to use and thus solves the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable bushing positioning device, comprising a base, a rectangular groove at the upper end of the base, a movable plate inside the rectangular groove, a lead screw at one end of the movable plate, a first motor for driving the lead screw to rotate fixedly installed at the end of the base, a hydraulic rod at the upper end of the movable plate, a placement plate at the upper end of the hydraulic rod, a bushing at the upper end of the placement plate, two symmetrical positioning clamps inside the bushing, a bidirectional threaded lead screw below the positioning clamps for driving the two positioning clamps to move synchronously in opposite directions or out of direction, a second motor for driving the bidirectional threaded lead screw to rotate on one side of the placement plate, symmetrical clamping plates on both sides of the upper end of the base, and an electric telescopic rod on the back of the clamping plates.
[0007] Furthermore, a fixed rod passes through the side of the movable plate away from the lead screw. The fixed rod is slidably connected to the inside of the movable plate. The two ends of the fixed rod are fixedly connected to the inner walls of the two ends of the rectangular groove. The lead screw is threadedly connected to the inside of the movable plate. The two ends of the lead screw are rotatably connected to the inner walls of the two ends of the rectangular groove through bearings. One end of the lead screw extends outward to the outside of the base and is fixedly connected to the output end of the first motor.
[0008] Furthermore, a hydraulic rod is fixedly installed at the upper middle part of the movable plate, and the output end of the hydraulic rod is fixedly connected to the bottom end face of the placement plate.
[0009] Furthermore, a groove is provided at the upper end of the placement plate, and two symmetrical sliders are provided inside the groove. The sliders are fixedly connected to the bottom end of the positioning clamp rod. The sliders are slidably connected to the inner wall of the groove. The sliders are threadedly connected to a bidirectional threaded screw. The two ends of the bidirectional threaded screw are rotatably connected to the inner walls of the two ends of the groove through bearings. One end of the bidirectional threaded screw extends outward to the outside of the moving plate and is fixedly connected to the output end of the second motor.
[0010] Furthermore, symmetrical support plates are fixedly connected to both sides of the base, and electric telescopic rods are fixedly installed on the sides of the support plates. The output end of the electric telescopic rods is fixedly connected to the back of the clamping plate.
[0011] Furthermore, the outer surfaces of the clamping plates are all covered with a rubber anti-slip layer.
[0012] Furthermore, support legs are fixedly connected to the four corners of the lower end of the base.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This utility model provides an adjustable bushing positioning device. In use, the bushing first houses two positioning clamps inside it. Then, a second motor is started, driving a bidirectional threaded screw to rotate. This rotation causes the two positioning clamps to move synchronously outwards, fixing the inner wall of the bushing and ensuring unobstructed polishing of the outer wall. When polishing of the inner wall is required, a first motor is started, driving a screw to rotate and move a moving plate between the clamping plates. An electric telescopic rod then moves the clamping plates closer to the bushing, clamping the outer wall. The positioning clamps then move synchronously in opposite directions, releasing the fixing of the inner wall. A hydraulic rod moves a placement plate downwards, causing the positioning clamps to leave the bushing. Finally, the first motor is started again, reversing the screw to return the moving plate to its original position. This prevents the positioning clamps from interfering with the processing of the inner wall of the bushing, making it convenient to use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0021] To address the technical problem that the bushing's positioning and fixing method prevents effective grinding and polishing of the clamping position, thus affecting the polishing effect, such as... Figure 1-4 As shown, the following preferred technical solutions are provided:
[0022] An adjustable bushing positioning device includes a base 1, a rectangular groove 2 at the upper end of the base 1, a movable plate 3 inside the rectangular groove 2, a lead screw 4 at one end of the movable plate 3, a first motor 6 for driving the lead screw 4 to rotate fixedly installed at the end of the base 1, a hydraulic rod 7 at the upper end of the movable plate 3, a placement plate 8 at the upper end of the hydraulic rod 7, a bushing 13 at the upper end of the placement plate 8, two symmetrical positioning clamping rods 14 inside the bushing 13, a bidirectional threaded lead screw 11 for driving the two positioning clamping rods 14 to move synchronously towards or away from each other below the positioning clamping rods 14, a second motor 12 for driving the bidirectional threaded lead screw 11 to rotate on one side of the placement plate 8, symmetrical clamping plates 17 on both sides of the upper end of the base 1, and an electric telescopic rod 16 on the back of the clamping plates 17.
[0023] Specifically, in use, firstly, the bushing 13 houses the two positioning clamping rods 14. Then, the second motor 12 is started, driving the bidirectional threaded screw 11 to rotate. The rotation of the bidirectional threaded screw 11 causes the two positioning clamping rods 14 to move synchronously and outward, positioning and fixing the inner wall of the bushing 13, ensuring unobstructed polishing of the outer wall of the bushing 13. When polishing of the inner wall of the bushing 13 is required, the first motor 6 is started. The first motor 6 drives the screw 4 to rotate, moving the moving plate 3 between the clamping plates 17. Subsequently, the electric telescopic rod 16 moves the clamping plate 17 closer to the bushing 13, positioning and clamping the outer wall of the bushing 13. Then, the positioning clamping rods 14 move synchronously in opposite directions, releasing the positioning and fixing of the inner wall of the bushing 13. The hydraulic rod 7 drives the placement plate 8 to move downward, causing the positioning clamping rods 14 to leave the inside of the bushing 13. Finally, the first motor 6 is started again to drive the lead screw 4 to reverse, sending the moving plate 3 back to its original position. The purpose of this design is to quickly position and fix the inner wall of the placed bushing 13 through the two positioning clamping rods 14, so that the bushing 13 is not obstructed when grinding the outer wall. Then, the clamping plate 17 positions and clamps the outer wall of the bushing 13, and the positioning clamping rods 14 release the positioning and fixing of the bushing 13, thereby avoiding the positioning clamping rods 14 from affecting the processing of the inner wall of the bushing 13, making it convenient to use.
[0024] Furthermore, such as Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:
[0025] A fixed rod 5 passes through the side of the movable plate 3 away from the lead screw 4. The fixed rod 5 is slidably connected to the inside of the movable plate 3. The two ends of the fixed rod 5 are fixedly connected to the inner walls of the two ends of the rectangular groove 2. The lead screw 4 is threadedly connected to the inside of the movable plate 3. The two ends of the lead screw 4 are rotatably connected to the inner walls of the two ends of the rectangular groove 2 through bearings. One end of the lead screw 4 extends outward to the outside of the base 1 and is fixedly connected to the output end of the first motor 6. The purpose of this design is to drive the lead screw 4 to rotate by rotating the output end of the first motor 6, and the rotation of the lead screw 4 drives the movable plate 3 to perform reciprocating linear motion.
[0026] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:
[0027] A hydraulic rod 7 is fixedly installed at the upper middle part of the movable plate 3. The output end of the hydraulic rod 7 is fixedly connected to the bottom end of the placement plate 8. The purpose of this design is to drive the placement plate 8 to rise and fall by extending and retracting the output end of the hydraulic rod 7.
[0028] Furthermore, such as Figure 1 and Figure 3 As shown, the following preferred technical solutions are provided:
[0029] The upper end of the placement plate 8 is provided with a slide groove 9. Inside the slide groove 9, there are two symmetrical sliders 10. The sliders 10 are fixedly connected to the bottom end of the positioning clamp rod 14. The sliders 10 are slidably connected to the inner wall of the slide groove 9. The sliders 10 are threadedly connected to a bidirectional threaded screw 11. The two ends of the bidirectional threaded screw 11 are rotatably connected to the inner walls of the two ends of the slide groove 9 through bearings. One end of the bidirectional threaded screw 11 extends outward to the outside of the moving plate 3 and is fixedly connected to the output end of the second motor 12. The purpose of this design is to drive the bidirectional threaded screw 11 to rotate by the rotation of the output end of the second motor 12. The rotation of the bidirectional threaded screw 11 drives the two symmetrical sliders 10 to move synchronously towards or away from each other, thereby realizing that the two positioning clamp rods 14 move synchronously towards or away from each other.
[0030] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:
[0031] The base 1 has symmetrical support plates 15 fixedly connected to both sides. An electric telescopic rod 16 is fixedly installed on the side of the support plate 15. The output end of the electric telescopic rod 16 is fixedly connected to the back of the clamping plate 17. The purpose of this design is to drive the clamping plate 17 to move in the horizontal direction through the output end of the electric telescopic rod 16, thereby achieving clamping of the outer wall of the bushing 13.
[0032] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:
[0033] The outer sides of the clamping plate 17 are all covered with a rubber anti-slip layer 18. The purpose of this design is to increase the friction between the clamping plate 17 and the bushing 13 through the anti-slip layer 18, so as to prevent the bushing 13 from falling off.
[0034] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:
[0035] Support legs 19 are fixedly connected to the four corners of the lower end of the base 1. The purpose of this design is to provide stable support for the device at the upper end through the support legs 19.
[0036] In summary: During use, firstly, the bushing 13 is fitted with the two positioning clamps 14 inside it. Then, the second motor 12 is started, which drives the bidirectional threaded screw 11 to rotate. The rotation of the bidirectional threaded screw 11 causes the two positioning clamps 14 to move synchronously and outward, positioning and fixing the inner wall of the bushing 13. This ensures that the outer wall of the bushing 13 is not obstructed during polishing. When polishing of the inner wall of the bushing 13 is required, the first motor 6 is started. The first motor 6 drives the screw 4 to rotate, moving the moving plate. 3. Move between the clamping plates 17, then the electric telescopic rod 16 drives the clamping plates 17 to approach the bushing 13, positioning and clamping the outer wall of the bushing 13. Then the positioning clamping rod 14 moves synchronously in opposite directions, releasing the positioning and fixing of the inner wall of the bushing 13. The hydraulic rod 7 drives the placement plate 8 to move downward, causing the positioning clamping rod 14 to leave the inside of the bushing 13. Finally, the first motor 6 is started again to drive the lead screw 4 to reverse, sending the moving plate 3 back to its original position, thereby avoiding the positioning clamping rod 14 from affecting the processing of the inner wall of the bushing 13, making it convenient to use.
