DETAILED DESCRIPTION

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-4The utility model is an angle-adjustable grinding machine, comprising a conveyor belt 1, both sides of the conveyor belt 1 are connected with side plates 2 through rotating rods, an adjusting cam 3 is set above one of the side plates 2, the adjusting cam 3 is away from the side plate 2 and the side wall opposite to the conveyor belt 1 is detachably connected with a first telescopic rod 4, the output end of the first telescopic rod 4 is detachably connected with a connecting column 5, the bottom end of the connecting column 5 is telescopically connected with a movable rod 8, a grinding sheet 6 is set below the movable rod 8, the inside of the connecting column 5 is evenly fixedly connected with a pressing spring 10, one end of the movable rod 8 located in the connecting column 5 is fixedly connected to the bottom end of the pressing spring 10, a second motor 11 is detachably inlaid and connected in the middle of a side of the movable rod 8 away from the pressing spring 10, and the grinding sheet 6 is detachably connected to the output end of the second motor 11.

[0018] The technical effect of this scheme is: the workpiece is placed on the conveyor belt 1 and sent to a suitable position, and then the No. 1 motor 9 is turned on to drive the adjusting cam 3 to rotate. The rotation of the adjusting cam 3 can drive the grinding sheet 6 to move synchronously, so as to realize the function of adjusting the orientation angle. According to this function, the workpiece can be comprehensively polished. In order to be able to comprehensively process the workpiece, the connecting column 5 is connected to the adjusting cam 3 through the No. 1 telescopic rod 4. The connecting column 5 can be driven by the adjusting cam 3 to move horizontally, thereby driving the grinding sheet 6 to move back and forth on the workpiece to avoid omissions in processing and ensure the processing effect.

[0019] A motor No. 9 is detachably connected to the side wall of one end of the adjusting cam 3 near the side plate 2, and a follower block 15 is detachably connected to the outer wall of the motor No. 9. A movable groove 12 is opened inside the side plate 2 near the follower block 15, and a slider 14 is fixedly connected to the bottom side wall of the follower block 15. The slider 14 is slidably connected in the movable groove 12. A No. 2 telescopic rod 13 is inlaid and connected to one side of the side plate 2 located at the movable groove 12. The output end of the No. 2 telescopic rod 13 extends into the movable groove 12 and is detachably connected to one side of the slider 14. A pressing plate 7 is set at one end of the conveyor belt 1 near the adjusting cam 3. The pressing plate 7 is a concave structure, and the pressing plate 7 is fixedly connected to the top side walls of the two side plates 2 through its bottom ends.

[0020] The technical effect of this solution is as follows: to ensure that the grinding sheet 6 is always in contact with the workpiece, a pressing spring 10 is set in the connecting column 5 to push the movable rod 8 downward, and the grinding sheet 6 is made to fit the workpiece through this thrust, so that the raised or recessed areas on the workpiece can be effectively contacted and ground, avoiding that some areas are not effectively ground due to unstable contact between the grinding sheet 6 and the workpiece. By setting up the No. 2 telescopic rod 13 and the slider 14, the movable range of the grinding sheet 6 can be increased on the basis of the No. 1 telescopic rod 4, further increasing the effective range of grinding.

[0021] Specifically, when the utility model is used, the workpiece is sent to the designated position through the conveyor belt 1. In order to avoid processing failure due to shaking of the workpiece during processing, a pressing plate 7 is set up to press the workpiece to ensure the stability of the workpiece during processing. Then, the No. 2 telescopic rod 13 is started as needed to move the adjusting cam 3 to a suitable position, and then the No. 1 motor 9 is started to drive the adjusting cam 3 to rotate. After adjusting to a suitable orientation angle, the No. 2 motor 11 is started to drive the grinding disc 6 to rotate at high speed to grind the workpiece. During the grinding process, the No. 1 telescopic rod 4 is started as needed, and the connecting column 5 is driven to move back and forth by the No. 1 telescopic rod 4 to perform a comprehensive grinding process on the workpiece in the horizontal direction. At the same time, the No. 2 telescopic rod 13 can be started to cooperate with the No. 1 telescopic rod 4 to perform a comprehensive processing of the workpiece.
