Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to an automatic abrasive adding device for arc hole grinding. Background Technology

[0002] In mechanical manufacturing, the grinding of arc holes is a crucial process, as its quality directly affects the performance and service life of parts. Currently, spiral arc hole grinding machines are often used in this process. The principle is as follows: using steel or copper wire as the grinding tool, the workpiece is first threaded onto the tool, with one end fixed. The tool is placed on the outer circumference of a bakelite roller, forming an angle with its axis. The other end is secured with a weight. The outer circumference of the bakelite roller has triangular spiral grooves. The operator uses their left finger to hold the workpiece behind, manually separating and removing the workpiece from the front, feeding it onto the bakelite roller. On the wheel, each workpiece is spaced apart and continuously fed to the outer circumference of the roller. The operator uses a brush in their right hand to apply diamond powder paste to the grinding tool for grinding the inner hole. When the workpiece enters the spiral groove on the rotating roller from one side, it will move in a straight line along the spiral groove of the rotating roller. At the same time, because there is an angle between the grinding tool and the axis of the bakelite roller, the workpiece will also oscillate slightly relative to the axis of the grinding tool as it moves forward through each pitch. Through the grinding action of the abrasive on the grinding tool, the inner hole is ground from a straight hole into a trumpet hole with arcs at both ends.

[0003] However, in the traditional arc hole grinding process, it is often necessary for personnel to manually apply abrasive to the surface of the grinding tool. In the process of frequent operation, the manual addition method not only consumes a lot of time and energy of personnel, but also greatly increases the labor intensity of personnel and affects the efficiency of processing operations.

A first support frame 2 is fixedly connected to the right end of the top of the worktable 1. A first guide wheel 15 is movably connected to the top of the first support frame 2 through a bearing. A second support frame 4 is fixedly connected to the left end of the top of the worktable 1. A second guide wheel 12 is movably connected to the right end of the top of the second support frame 4 through a bearing. A gap is placed between the top of the second guide wheel 12 and the top of the first guide wheel 15. A steel wire abrasive tool 5 is placed on the top of the workbench 1 and is fixedly connected to the rear of the first motor 9. A fixed box 18 is fixedly installed on the top of the inner cavity of the fixed box 18. An adjusting screw 20 is fixedly installed on the output end of the second motor 19. A lifting frame 22 is threadedly connected to the lower end of the adjusting screw 20. An abrasive box 7 is fixedly connected to the top of the lifting frame 22. A baffle 8 is fixedly connected to the top of the outer surface of the workbench 1 and is fixedly connected to the rear of the fixed box 18. An electric push rod 16 is fixedly installed in the middle of the baffle 8. A brush 6 is fixedly installed on the output end of the electric push rod 16.

[0024] In this technical solution, after the diamond grinding powder paste required for the grinding operation is added into the grinding box 7, when it is necessary to add abrasive to the surface of the wire grinding tool 5, the second motor 19 is started by the external controller, which drives the adjusting screw 20 to rotate and moves the lifting frame 22 and the grinding box 7 upward, so that the abrasive inside the grinding box 7 can come into contact with the coating brush 6 and adhere to the surface of the coating brush 6. Then, by starting the second motor 19, the adjusting screw 20 is rotated in the other direction, so that the lifting frame 22 and the grinding box 7 can move downward and reset. At the same time, the electric push rod 16 is extended by controlling it to push the coating brush 6 to move, so that the surface of the coating brush 6 can come into contact with the surface of the wire grinding tool 5, and the abrasive adhering to the surface of the coating brush 6 can be applied to the surface of the wire grinding tool 5, thereby achieving the effect of automatic abrasive addition, so as to facilitate the subsequent arc hole grinding operation of the workpiece.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a weight 3 is suspended at the right end of the wire grinding tool 5.
