[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] Please refer to the attached Figure 1-4 The utility model provides an engine shaft processing tool, comprising a base 1 and an engine camshaft 2. A right-angle frame 3 is fixedly installed on the rear side of the top of the base 1. The engine camshaft 2 is detachably arranged on the top of the base 1 through a clamping component. A processing component for grinding the surface of the engine camshaft 2 is connected to the top of the right-angle frame 3 through an adjusting component.

[0021] The clamping assembly includes two vertically arranged support plates 4, the bottom ends of the two support plates 4 are symmetrically fixedly mounted on the two ends of the top of the base 1, and an electric push rod 5 is fixedly mounted on the top of the side end of the support plate 4 located on one side of the top of the base 1. It should be noted that the electric push rod is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. In the utility model, the electric push rod can also be replaced by a cylinder, a hydraulic cylinder and other structures. The output shaft of the electric push rod 5 passes through the support plate 4, and a three-jaw chuck 6 is rotatably mounted on the output shaft of the electric push rod 5. It should be noted that the three-jaw chuck refers to a machine tool accessory that clamps and positions the workpiece by radial movement of three movable jaws evenly distributed on the chuck body. Therefore, when the electric push rod 5 is running, it can drive the three-jaw chuck 6 to move back and forth horizontally, and the three-jaw chuck 6 can rotate freely, thereby facilitating the control of the loading and unloading operations of the engine camshaft 2;

[0022] A servo motor 7 and a reducer 8 are fixedly installed on the top of the side end of the support plate 4 located on the other side of the top of the base 1. The output shaft of the servo motor 7 passes through the support plate 4, and the output shaft of the servo motor 7 is fixedly connected to the input shaft of the reducer 8. The output shaft of the reducer 8 is fixedly installed with a three-jaw chuck 2 9. Therefore, under the deceleration effect of the reducer 8, when the servo motor 7 is running, the three-jaw chuck 2 9 can be driven to rotate slowly. The three-jaw chuck 1 6 corresponds to the three-jaw chuck 2 9 horizontally. The two ends of the engine camshaft 2 are clamped and fixed by the three-jaw chuck 1 6 and the three-jaw chuck 2 9 respectively. Therefore, when the servo motor 7 runs and drives the three-jaw chuck 2 9 to rotate slowly, the engine camshaft 2 can be controlled to rotate slowly;

[0023] The adjustment component includes a horizontally arranged electric linear slide 10. It should be noted that in the present utility model, the electric linear slide 10 is preferably set to a ball screw type, which is an automated transmission element that uses a ball screw (not marked in the figure) to drive a slider (not marked in the figure) to move. The top of the electric linear slide 10 is horizontally fixedly installed on the lower surface of the top of the right-angle frame 3, and an electric push rod 2 11 is vertically fixedly installed at the bottom of the output end of the electric linear slide 10, that is, when the electric linear slide 10 is running, it can drive the electric push rod 2 11 to move back and forth horizontally;

[0024] The processing assembly includes a shell 12, the top of which is fixedly mounted on the bottom end of the output shaft of the electric push rod 11, that is, the shell 12 can move back and forth synchronously with the electric push rod 11, and when the electric push rod 11 is running, the shell 12 can be driven to rise and fall. A limit hole 13 is provided at the bottom center of the shell 12, and a guide rod 14 vertically penetrates the limit hole 13. A limit plate 15 is fixedly mounted on the top of the guide rod 14, and a return spring 16 is fixedly mounted on the top of the limit plate 15. The top of the return spring 16 is fixedly connected to the top of the inner wall of the shell 12, so when the guide rod 14 moves upward, the return spring 16 can be compressed by the limit plate 15, so that the return spring 16 undergoes elastic deformation to generate a reaction force, and a C-shaped mounting plate 17 is longitudinally fixedly mounted on the bottom end of the guide rod 14, and a grinding belt 18 is longitudinally fixedly mounted on the inner side of the C-shaped mounting plate 17. The lower surface of the grinding belt 18 conflicts with the surface of the engine camshaft 2, that is, the rotating engine camshaft 2 The surface can be effectively polished by the grinding belt 18, and when the engine camshaft 2 rotates to the point where the convex surface conflicts with the grinding belt 18, the grinding belt 18 can be squeezed to make the C-shaped mounting plate 17 move up, thereby making the guide rod 14 move up, and when the engine camshaft 2 rotates to the point where the concave surface conflicts with the grinding belt 18, the grinding belt 18 is no longer subjected to the squeezing force, and at this time, under the reaction force of the return spring 16, the grinding belt 18 can be moved down, so that the grinding belt 18 can continue to conflict with the uneven surface of the engine camshaft 2 well, and the grinding belt 18 can be controlled to move back and forth laterally by the electric linear slide 10, and the grinding belt 18 can be controlled to rise and fall by the electric push rod 11, that is, to perform a feeding motion, so that the uneven surface of the engine camshaft 2 can be automatically polished well, without the need for manual hand-held polishing operations, thereby improving the polishing efficiency and saving manpower.

[0025] The use process of the utility model is as follows: the technicians in this field first clamp and fix the two ends of the engine camshaft 2 to be polished by the three-jaw chuck 1 6 and the three-jaw chuck 2 9, then turn on the electric linear slide 10, control the grinding belt 18 to move to the initial position of one end of the engine camshaft 2, and then control the grinding belt 18 to move down to the surface of the engine camshaft 2 through the electric push rod 2 11, and operate the servo motor 7 to control the rotation of the engine camshaft 2, so that the surface of the engine camshaft 2 can be effectively polished by the grinding belt 18, and when the engine camshaft 2 rotates to the surface When the convex surface of the surface conflicts with the grinding belt 18, the grinding belt 18 can be squeezed to make the C-shaped mounting plate 17 move up, thereby making the guide rod 14 move up. When the guide rod 14 moves up, the return spring 16 can be compressed by the limit plate 15, so that the return spring 16 undergoes elastic deformation to generate a reaction force. When the engine camshaft 2 rotates to the concave surface of the surface conflicts with the grinding belt 18, the grinding belt 18 is no longer subjected to the squeezing force. At this time, under the reaction force of the return spring 16, the grinding belt 18 can be moved down, that is, the grinding belt 18 can be well maintained to conflict with the uneven surface of the engine camshaft 2.

[0026] Then the technicians in this field repeat the above operation, control the grinding belt 18 to move step by step toward the other end of the engine camshaft 2 through the electric linear slide 10, and control the grinding belt 18 to make corresponding feeding movement through the electric push rod 11, so that the uneven surface of the engine camshaft 2 can be automatically polished well without manual hand-held polishing operation, thereby improving the polishing efficiency and saving manpower.

[0027] The above is only a preferred embodiment of the utility model. Any person skilled in the art can modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
