Embodiment Construction

[0023] The device and method for rapid processing of polygonal inner holes according to the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] like figure 1 As shown, a polygonal inner hole rapid processing device according to the present invention includes a tool 11 , a connecting rod 12 and a rotating mechanism 13 connected in sequence.

[0025] like figure 2 As shown, the cutter 11 includes a cutter head 1 and a cutter bar 2 made of high-speed steel as a whole, the rake angle of the cutter head 1 is 0°, and the rear angle of the cutter head 1 is sharpened at 1°; The positioning hole 3 matched with the threaded hole 5 of the connecting rod 12. Other dimensions of the cutter head 1 need to be sharpened according to the actual production size requirements.

[0026] like image 3 As shown, the front end of the connecting rod 12 is a knife rod sleeve 4, and a threaded hole 5 is provided at the p...

Abstract

The invention provides a fast processing device and method for a polygonal inner hole. The device comprises a cutter, a connecting bar and a rotating mechanism which are sequentially connected. The method comprises the steps as follows: a workpiece is clamped on a lathe chuck, and a technological bottom hole inside the workpiece is processed; the connecting bar is mounted into the rotating mechanism, the cutter is mounted into the connecting bar, and then a solid shaft end of the rotating mechanism is mounted into a lathe tailstock sleeve which is connected with a machine tool tailstock; a cutting mode that the workpiece and the cutter rotate simultaneously is adopted; under the condition that the workpiece is tightly attached to the cutter, when a lathe spindle rotates, friction of a contact surface with the cutter can drive the cutter to rotate tending to the same speed under the action of rotational inertia of the workpiece; and after the rotation is stable, the lathe tailstock can be shaken to perform cutter feed motion so as to finish the cutting operation of the polygonal square hole. The fast processing device and method for the polygonal inner hole have the benefits that processing of the polygonal inner hole on the lathe can be realized, clamping positioning is performed once in a manufacturing process, and the processing precision is guaranteed.

Description

technical field [0001] The invention relates to mechanical manufacturing technology, in particular to a device and method for rapid processing of polygonal inner holes. Background technique [0002] At this stage, the equipment for polygonal inner hole processing mainly includes punching machines, EDM machine tools, wire cutting machine tools, etc. In the case of low precision requirements, punching is mainly used for processing, and polygonal square holes are processed side by side by inserting cutters, and the manufacture of bottom holes needs to be completed on other equipment, which must be positioned through secondary clamping. Therefore, it is conceivable that the efficiency of the punching machine for polygonal inner hole preparation is low, and the processing quality often cannot meet the requirements of high precision. With the continuous development of the manufacturing industry, special processing technology has been widely promoted in production. In the machini...
