Description

Technical Field

[0001] This utility model relates to the field of bushing trimming technology, specifically a bushing trimming device. Background Technology

[0002] Bushings are fittings used on the outside of mechanical parts to achieve functions such as sealing and wear protection. They are rings that act as gaskets. In moving parts, long-term friction causes wear on the parts. When the clearance between the shaft and the hole wears to a certain extent, the parts must be replaced. Therefore, in the design, materials with low hardness and good wear resistance are selected for bushings or bushings. This can reduce the wear of the shaft and the seat. When the bushing or bushing wears to a certain extent, it can be replaced, which can save the cost of replacing the shaft or seat.

[0003] For example, utility model patent CN22096696U discloses a bushing trimming device for automobile chassis suspension, including a base and a first U-shaped frame. The first U-shaped frame is fixedly connected to the top of the base, and a first cylinder is fixedly connected to the top of the first U-shaped frame. The output end of the first cylinder extends into the interior of the first U-shaped frame and is fixedly connected to a second U-shaped frame. A second cylinder is fixedly connected to the outer side of the second U-shaped frame, and the output end of the second cylinder extends into the interior of the second U-shaped frame and is fixedly connected to a sliding block. The beneficial effect of this utility model is that the operator can adjust the angle of the second cylinder and then use the second U-shaped frame to trim the bushing. The cooperation between the frame and the second cylinder enables the bushing trimming process to be fully automated and precise without the need for manual position adjustment. This significantly improves the work efficiency of the workers and the production speed of the bushings. Compared with traditional devices, it greatly improves the work quality and efficiency. However, the bushing trimming action can only be performed on one end of the bushing. When the other end of the bushing needs to be trimmed, the bushing needs to be manually flipped and then clamped, which reduces the efficiency of bushing trimming. To address this, we propose a bushing trimming device. Utility Model Content

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 Figures 1-4This utility model provides a technical solution: a bushing trimming device, including a base plate 1, with two symmetrically arranged sliding grooves 2 on the rear side of the upper end of the base plate 1, a bushing centering rotation mechanism 3 and a bushing trimming mechanism 4 arranged on the upper end of the base plate 1, the bushing trimming mechanism 4 being arranged on the upper part of the bushing centering rotation mechanism 3, the bushing centering rotation mechanism 3 being used to center and clamp the bushing and perform a rotation action, and the bushing trimming mechanism 4 being used to trim the outer circumferential surface of the bushing and the two end faces of the bushing.

[0023] In this embodiment, the bushing centering rotation mechanism 3 includes two symmetrically arranged first vertical plates 31.

[0029] In this embodiment, the outer end of the first rotating shaft 33 passes through the right first vertical plate 31, and the left end of the first rotating shaft 33 is rotatably connected to the left first vertical plate 31 through a bearing.

[0030] Specifically, it ensures that the first rotating shaft 33 does not interfere with the first vertical plate 31 during rotation.

[0035] In this embodiment, each C-shaped movable plate 37 is fixedly installed with a slide bar 312 at its lower end, and the outer end of each slide bar 312 is slidably connected to a slide groove 2.

[0036] Specifically, this ensures that the C-shaped moving plate 37 can directly drive the slide bar 312 to perform stable sliding action in the slide groove 2 during the movement process, thereby improving the stability of the C-shaped moving plate 37 during the movement process.

[0037] Working principle: In use, the bushing can be placed between the two bushing clamping assemblies 38. Then, the second stepper motor 311 is started. The output end of the second stepper motor 311 drives the first rotating rod 39 to rotate. At this time, the first rotating rod 39 drives the two symmetrically arranged C-shaped moving plates 37 to move closer or further apart. Each C-shaped moving plate 37 drives the second rotating shaft 36 and the short gear 35 to move. At this time, the short gear 35 and the long gear 34 slide relative to each other. When the bushing clamping assembly 38 clamps the bushing... After clamping on both sides, the first stepper motor 32 can be started. The output end of the first stepper motor 32 drives the first rotating shaft 33 to rotate. The first rotating shaft 33 drives the long gear 34 to rotate. The long gear 34 drives each short gear 35 to rotate in the opposite direction. The short gear 35 drives the second rotating shaft 36 and the bushing clamping assembly 38 to rotate. The two bushing clamping assemblies 38 drive the bushing to rotate. Next, the bushing trimming mechanism 4 can trim the outer circumference and both end faces of the bushing.
