[0021] The following is a combination of the appended examples of the present invention Figure 1-5 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] As shown in the figure, a mold guide column chamfering device includes a frame 1, a lifting frame 2 which can slide longitudinally and is transmission-connected to a cylinder 3 provided on the frame 1, a rotating disk 4 which is transmission-connected to a first motor 5 provided on the lifting frame 2 is rotatably provided on the lower end of the lifting frame 2, the first motor 5 is a reduction motor, a plurality of jackets 6 which are rotatably arranged along a central annular array of the rotating disk 4 are rotatably provided on the rotating disk 4, the jacket 6 has a clamping cavity 61 with an opening facing downward, a gear 7 is fixedly connected to the rotating shaft of the jacket 6, a gear ring 8 which surrounds a plurality of clamps and meshes with the gear 7 is provided on the lifting frame 2, a blanking port 9 which is opposite to the rotating disk 4 is opened on the frame 1, a grinding wheel 10 which is transmission-connected to a second motor 11 provided on the frame 1 is rotatably provided on the frame 1, and the upper end of the grinding wheel 10 is frustum-shaped and passes through the blanking port 9.

[0023] Specifically, the lifting frame 2 is slidably arranged on the frame 1 and is transmission-connected to the first motor 5: a gantry 12 is provided on the frame 1, and a plurality of linear slide rails 13 are provided on the gantry 12 on both sides of the lifting frame 2; the lifting frame 2 is fixedly connected to the sliding seat of the linear slide rail 13; the cylinder 3 is arranged on the gantry 12 and the output shaft of the cylinder 3 passes downward through the gantry 12 and is fixedly connected to the lifting frame 2.

[0024] Specifically, the grinding wheel 10 is rotatably set on the frame 1 and is transmission-connected to the second motor 11: the frame 1 is fixedly connected to a support frame 14 located below the blanking port 9, the grinding wheel 10 is rotatably set on the support frame 14 and the rotating shaft of the grinding wheel 10 is transmission-connected to the second motor 11 through the cooperation of a synchronous wheel and a synchronous belt.

[0025] In the above structure, a number of guide pins to be chamfered are inserted into the clamping cavity 61 of the jacket 6 and fixed in the clamping cavity 61 of the jacket 6 by the expansion action with the inner wall of the clamping cavity 61, and the lower end protrudes from the clamping cavity 61. Then the first motor 5 drives the rotating disk 4 to rotate, and the rotating disk 4 drives the plurality of jackets 6 and the guide pins to perform orbital motion along the center of the rotating disk 4. When the jacket 6 performs orbital motion, the gear 7 and the gear ring 8 cooperate to drive the fixture and the guide pins to perform self-rotation motion on the rotating disk 4. At the same time, the cylinder 3 drives the lifting frame 2 to move upward on the linear slide rail 13. The guide post slides downward and drives the sleeve 6 and the guide post to move toward the grinding wheel 10. In the process of the guide post gradually moving downward, the edge of the lower end of the guide post contacts the side of the frustum-shaped upper end of the grinding wheel 10 driven by the second motor 11, so that the grinding wheel 10 cuts the edge of the lower end of the guide post to form a chamfer. In this way, the chamfering of the guide post can be completed quickly by the rotation of the grinding wheel 10 in coordination with the revolution and rotation of the guide post, and multiple guide posts in multiple sleeves 6 can be chamfered at the same time, thereby improving production efficiency.

[0026] In addition, two expansion slots 62 that pass through the jacket 6 downward are symmetrically provided at the lower end of the jacket 6. Two clamping ears 63 are fixedly connected to the jacket 6 on both sides of the expansion slot 62. The two clamping ears 63 are fastened by a bolt pair 64. After the guide column is inserted into the clamping cavity 61, the clamping ears 63 on both sides of the same expansion slot 62 are tightened by tightening the bolt pair 64 to shrink the expansion slot 62, so that the lower end of the jacket 6 is deformed toward the guide column and pressed against the guide column, thereby increasing the friction between the jacket 6 and the guide column, so that the guide column is more firmly maintained in the clamping cavity 61 and moves with the jacket 6, thereby ensuring the accuracy of chamfering.

[0027] In addition, an anti-skid pad layer 65 is provided on the inner wall of the clamping cavity 61. The anti-skid pad layer 65 not only strengthens the friction between the jacket 6 and the guide post, but also protects the outer wall of the guide post to prevent the outer wall from being scratched when the jacket 6 clamps the guide post.

[0028] In addition, a guide wheel 15 is rotatably provided on the upper end of the rotating shaft of the grinding wheel 10, and a guide ring 16 is fixedly connected to the frame 1 around the blanking port 9 and concentric with the guide wheel 15. A guide channel 17 is formed between the guide wheel 15 and the guide ring 16. When the guide column moves downward and contacts the grinding wheel 10 for chamfering, the lower end of the guide column extends into the guide channel 17 between the guide wheel 15 and the guide ring 16. The guide channel 17 guides the guide column as it revolves and rotates with the jacket 6, so that the guide column can cooperate with the grinding wheel 10 more stably during the revolution and rotation, thereby ensuring the accuracy of the chamfering.

[0029] In addition, the support frame 14 is in the shape of a cylinder with an opening upward, so that a collection chamber 141 connected to the blanking port 9 is formed inside the support frame 14, and a collection pipe 142 connected to the collection chamber 141 is connected to the outer wall of the support frame 14, and the collection pipe 142 is connected to an external dust collection device. The debris generated by the grinding wheel 10 when cutting and chamfering the guide column enters the collection chamber 141 through the blanking port 9 by the suction force generated by the dust collection device, and is sucked away by the dust collection device after passing through the collection pipe 142, so that the debris is collected in a centralized manner, thereby preventing the debris from splashing during the chamfering process, which is beneficial to the personal health of the workers and the cleanliness of the working environment.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
