[0002] An automobile rocker arm is an important metal fitting of an internal combustion engine automobile. The automobile rocker arm is installed on a rocker arm shaft and is used to control the opening and closing of the intake and exhaust valves of the automobile engine cylinder. The automobile rocker arm has a bent arm lever. There is a rocker arm shaft hole in the middle of the bent arm lever. There is an oil hole on the bent arm lever that communicates with the rocker arm shaft hole. One end of the bent arm lever is a driving end, and there is a driving bearing mounting hole at the driving end. The other end of the bent arm lever is a triggering end, and there is a hydraulic tappet inlay hole at the triggering end. When the automobile rocker arm is installed, the shaft bushing is an essential part.
[0003] According to a grinding device for an automobile rocker arm shaft bushing described in the patent number CN209288888U, it is impossible to load and unload a single workpiece during grinding, and only batch processing can be carried out, resulting in low processing efficiency. Content of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides an automobile bushing polishing and processing device, which solves the above-mentioned problems.
[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: an automobile bushing polishing and processing device, including a processing table. A rotating disk driven by a rotating motor is rotatably connected to the top of the processing table. A grinding wheel is driven by a motor at the center of the rotating disk. The surface of the rotating disk is slidably connected with a plurality of placement stations arranged in a circular array. A plugging rod adapted to the inner cavity of the bushing is rotatably connected to the top of the placement station. A return spring is fixedly connected to the inner cavity of the rotating disk. One end of the return spring is fixedly connected to one side of the placement station close to the grinding wheel. A limiting ring in contact with the side of the placement station is fixedly connected to the side of the processing table. An upper and lower material slot is opened on the surface of the limiting ring above 22.5 degrees - 112.5 degrees of the rotating disk. A driven gear is fixedly connected to the surface of the plugging rod. A toothed ring meshing with the surface of the driven gear is fixedly connected to the side of the limiting ring. The toothed ring is an arc arranged above the position of 112.5 degrees - 22.5 degrees of the rotating disk. When in use, the bushing is placed on the plugging rod of the placement station at the loading station. Then the rotating disk drives the placement station to rotate. The chamfer contacts the side of the limiting ring, and then the return spring is compressed. The placement station moves towards the center of the rotating disk, driving the bushing to abut against the surface of the grinding wheel for grinding. And at this time, the bushing moves to the lower part of the workpiece upper limiting frame for limiting. While the grinding wheel grinds the bushing, the rotating disk rotates. At this time, the driven gear on the surface of the plugging rod is meshed with the toothed ring, driving the plugging rod to rotate self, and the bushing rotates self. The grinding of all surfaces of multiple bushings is carried out in all directions by a single grinding wheel. Then it moves to the unloading station. The placement station gradually moves outwards under the push of the return spring, driving the bushing to rotate and move horizontally at the same time. At this time, the bushing contacts the pushing guide rail and is pushed by the pushing guide rail to move upwards, gradually separating from the plugging rod, and then completing the discharging through the guiding of the guiding frame. It can automatically carry out unloading while rotating itself without manual operation.
[0006] As a further scheme of the utility model: there are eight placement stations. The placement stations above 22.5 - 67.5 degrees of the rotating disk are loading stations, and the placement stations above 67.5 degrees - 112.5 degrees of the rotating disk are unloading stations. When the rotating disk drives the placement stations to rotate to the loading station and the unloading station, the return spring drives the placement stations to move outwards, driving the bushing to separate from the grinding wheel. At this time, the upper and lower material operations can be carried out.
[0007] As a further solution of the utility model: a workpiece upper limit frame is fixedly connected to the top of the limit ring. The workpiece upper limit frame is composed of two arcs arranged on both sides of the insertion rod, and is an arc located above the position of 112.5 degrees - 22.5 degrees of the rotating disc. The bottom of the workpiece upper limit frame abuts against the surface of the bushing. When in use, the insertion rod drives the bushing to rotate below the workpiece upper limit frame, and the workpiece upper limit frame presses on the upper part of the bushing to perform upper limit and prevent it from disengaging.
[0008] As a further solution of the utility model: chamfers are provided on both sides of the outer circle of the placement station. Through the setting of the chamfers, when the placement station rotates at the loading and unloading chute, the chamfers contact the side of the limit ring, then compress the return spring, and the placement station moves towards the center of the rotating disc, driving the bushing to abut against the surface of the grinding wheel for grinding.
[0009] As a further solution of the utility model: a pushing guide rail is fixedly connected to the inner cavity of the limit ring and is located above the rotating disc at 67.5 degrees - 112.5 degrees. The pushing guide rail gradually rises from left to right. The leftmost side is lower than the lowest position when the bushing is placed, and the rightmost side is higher than the highest position of the insertion rod. A guiding frame is fixedly connected above the limit ring and is located above the pushing guide rail. Through the setting of the pushing guide rail, when the placement station drives the bushing to rotate to the unloading station, at this time, the placement station gradually moves outwards under the push of the return spring, drives the bushing to rotate and move horizontally at the same time. At this time, the bushing contacts the pushing guide rail and is abutted by the pushing guide rail to move upwards, gradually disengages from the insertion rod, and then completes discharging through the guiding of the guiding frame. It can automatically discharge while rotating itself without manual operation.
[0010] The utility model has the following beneficial effects compared with the prior art:
[0011] 1. In the utility model, when in use, the bushing is placed on the insertion rod of the placement station at the loading station, and then the rotating disc drives the placement station to rotate. The chamfer contacts the side of the limit ring, then compresses the return spring, and the placement station moves towards the center of the rotating disc, driving the bushing to abut against the surface of the grinding wheel for grinding. While the grinding wheel grinds the bushing, the bushing rotates itself. The single grinding wheel can comprehensively grind all surfaces of multiple bushings at the same time, and the loading and unloading will not be affected by the grinding wheel, and continuous loading and unloading can be carried out without stopping the machine.
[0012] 2. In the utility model, the placement station gradually moves outwards under the push of the return spring, drives the bushing to rotate and move horizontally at the same time. At this time, the bushing contacts the pushing guide rail and is abutted by the pushing guide rail to move upwards, gradually disengages from the insertion rod, and then completes discharging through the guiding of the guiding frame. It can automatically discharge while rotating itself without manual operation. Brief Description of the Drawings
