The inner and outer ends of the drilled hole on the workpiece can be polished through the chamfering mechanism, which solves the problem that the hole inside the workpiece is inconvenient to chamfer, and helps to improve the efficiency of workpiece processing and other technical effects";

[0031] When existing CNC machine tools chamfer square or rectangular workpieces, it is inconvenient to place and fix the workpieces, and vibration is easily generated during chamfering. Generally, workpieces need to be placed and fixed manually during chamfering, which is troublesome to use. Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a movable fixing component 2 and a chamfering component 3 are added to the present application document.

[0032] According to the above content, in order to be able to automatically fix the workpiece while sending the workpiece to the grinding site, it also includes a mobile fixing component 2 installed above the frame 1; the mobile fixing component 2 includes a support 201 slidably connected to the frame 1, a motor 202 installed on the surface of one side of the frame 1, and a screw 203 rotatably connected to the top surface of the frame 1, one end of the screw 203 is installed on the output end of the motor 202, the screw 203 is spirally connected to the screw hole opened on the surface of the support 201, and the inclined surface of one side of the support 201 is An L-shaped pull plate 205 is slidably connected in the groove, and the pull plate 205 is slidably connected in the slide groove opened on the bottom surface of the support platform 201. A wedge-shaped frame 206 is installed on one side surface of the pull plate 205. An L-shaped push plate 204 is slidably connected in the card groove opened in the L-shaped structure of the pull plate 205. Bolts are spirally connected in the screw holes opened on both side surfaces of the push plate 204.

When the support 201 moves to the grinding position, the roller 209 on the top rod 208 pushes the wedge frame 206 on the pull plate 205, so that the wedge frame 206 drives the pull plate 205 to slide in the groove opened on the surface of the support 201, and at the same time, the push plate 204 in the groove opened on the surface of the pull plate 205 moves downward, and the L-shaped structure of the push plate 204 is against the surface of the workpiece to limit the workpiece. At the same time, the position and height of the workpiece can also be adjusted according to the size of the workpiece.

[0041] In this embodiment: after the workpiece moves to the grinding position, the turntable 301 is driven to rotate by the motor 2 302, so that the turntable 301 can drive the grinding roller 305 on the slider 303 to rotate. When the position where the square workpiece or the rectangular workpiece needs to be ground is ground and chamfered, the motor 3 304 on the slider 303 drives the grinding roller 305, so that two places of the workpiece can be ground at the same time, which greatly improves the grinding efficiency. At the same time, the slider 303 can be pushed by the multi-stage hydraulic rod 307, so that the slider 303 drives the grinding roller 305 to adjust the distance, so as to grind and chamfer workpieces of different sizes.

[0042] In an optional embodiment: a bracket 306 of an L-shaped structure is installed on one side surface of the slider 303 , and the bracket 306 is rotatably connected to the grinding roller 305 .

[0043] In this embodiment: the support 306 on the slider 303 provides support for the grinding roller 305 to prevent the grinding roller 305 from being deformed or broken during use.

[0044] The working principle and use process of the utility model are as follows: the workpiece is placed on the support 201, and then the motor 202 on the frame 1 drives the screw 203 to rotate on the bottom surface of the frame 1, and then the screw 203 drives the support 201 to move on the frame 1. When the support 201 moves to the grinding position, the roller 209 on the top rod 208 pushes the wedge frame 206 on the pull plate 205, so that the wedge frame 206 drives the pull plate 205 to slide in the groove opened on the surface of the support 201, and at the same time, the push plate 204 in the groove opened on the surface of the pull plate 205 moves downward, and when the wedge class on the pull plate 205 is separated from the roller 209 on the top rod 208, the spring 207 will lift the pull plate 205 to separate the push plate 204 from the workpiece, thereby ensuring the workpiece is polished. The open and closed state is maintained so that the L-shaped structure of the push plate 204 is against the surface of the workpiece to limit the workpiece. At the same time, the position and height of the workpiece can be adjusted according to the size of the workpiece. When the workpiece moves to the grinding position, the turntable 301 is driven to rotate by the motor 2 302, so that the turntable 301 can drive the grinding roller 305 on the slider 303 to rotate. When the position where the square workpiece or the rectangular workpiece needs to be ground is ground and chamfered, the grinding roller 305 is driven by the motor 3 304 on the slider 303, so that two places of the workpiece can be ground at the same time, which greatly improves the grinding efficiency. At the same time, the slider 303 can be pushed by the multi-stage hydraulic rod 307, so that the slider 303 drives the grinding roller 305 to adjust the distance, so as to grind and chamfer workpieces of different sizes.
