[0021] To make the purpose, content and advantages of the present invention clearer, the following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present invention.

[0022] As Figure 1 and 2 shown, a non-metal part chamfering tooling of the present invention disclosed in this embodiment includes a connection base 1, a fixing ring 3, and a chamfering net 2; the connection base 1 is a hollow structure, one end is connected to a dust extraction device, and the other end is provided with a chamfering net 2. The chamfering net 2 is fixed and pressed at the opening at the other end of the connection base 1 through the fixing ring 3, and the center of the chamfering net 2 is in a concave arc shape.

[0023] One end of the connection base 1 is a small-diameter cylindrical end, and the other end is a large-diameter cylindrical end. The inner diameter of the large-diameter cylindrical end is greater than the inner diameter of the small-diameter cylindrical end, and a tapered transition section is provided between the small-diameter cylindrical end and the large-diameter cylindrical end.

[0024] A flange ring that turns inward is formed at the port of the large-diameter cylindrical end. The periphery of the chamfering net 2 is attached to the flange ring and is pressed by the fixing ring 3.

[0025] The periphery of the chamfering net 2 is a circular ring part, and the shape and size of the circular ring part are consistent with those of the flange ring. The central part of the chamfering net 2 is an arc recessed towards the inner cavity of the large-diameter cylindrical end of the connecting base 1.

[0026] The fixing ring 3 is a cylindrical barrel, and a pressing ring is formed at the mouth part and turns inwards, and the pressing ring presses tightly on the circular ring net.

[0027] Internal threads are formed on the inner wall of the barrel of the fixing ring 3 and are in threaded fit connection with the external threads of the large-diameter cylindrical end.

[0028] The width of the pressing ring is smaller than the width of the circular ring part.

[0029] The connection between the circular ring part and the central part of the chamfering net 2 has a 90° bending angle at the inner circle of the flange ring.

[0030] The end face of the flange ring of the connecting base 1 is processed with mesh patterns to increase the contact friction force with the chamfering net 2.

[0031] In this embodiment, the connecting base 1 realizes the functions of directional return of chamfering dust and supporting the chamfering net 2, and the positioning ring 3 realizes the functions of fixing and pressing tightly and quickly replacing the chamfering net 2.

[0032] The connecting base 1 and the fixing ring 3 constitute the functions of fixing and dust suction guiding, and the fixing ring 3 and the chamfering net 2 constitute a chamfering device.

[0033] The periphery of the connecting base 1 is airtight, and the fixing ring 3 is connected to the connecting base 1 by threads; the fixing ring 3 fixes the chamfering net 2 on the connecting base 1. The chamfering net 2 is made of a grid-shaped anti-static textile material or a non-ferrous metal material, and the multi-edge contact and scraping of the edges of non-metallic cylindrical parts are used to realize the chamfering function. When chamfering non-metallic cylindrical parts, one end to be chamfered is pressed on the chamfering net 2, and the part is rotated to realize rapid chamfering, and the falling dust is directionally collected into the central hole of the connecting base 1. While no static electricity is generated, the part is ground and chamfered.

[0034] The process of the chamfering method using the non-metallic part chamfering tooling in this embodiment is as follows:

[0035] The non-metallic cylindrical part is placed flat on the mesh arc surface of the chamfering net 2 of this chamfering tooling, one end of the connecting base 1 is connected to the dust extraction equipment, the non-metallic cylindrical part is rotated, and the mesh structure of the chamfering net 2 scrapes against the edges of the non-metallic part on multiple sides, so as to realize the edge chamfering of the non-metallic part. The chamfered-off dust is adsorbed away from the dust suction pipeline of the connecting base 1, so as to realize real-time and rapid dust collection. The chamfering net 2 can be made of a non-metallic mesh textile material product or a non-ferrous metal mesh material product.

[0036] The utility model is applicable to a chamfering tooling for non-metal cylindrical parts. By scraping and other means between the edges of the cylindrical parts and the mesh structure material, the edge chamfering of the non-metal cylindrical parts is realized, and it is applicable to non-metal parts that cannot be chamfered by cutting and scraping and grinding methods such as metal cutting tools.

[0037] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the utility model.
