Abstract

The utility model discloses a boring cutter for processing a front cover and a rear cover of an automotive compressor, which comprises a cutter body. One side of the front end of the cutter body is provided with a cutting part, and the nose of the cutting part adopts a circular chamfered structure. Since the right-angled chamfered structure of the nose of the cutting part is changed into the circular chamfered structure, the utility model greatly improves the accuracy of the work piece to be cut and also the finish and other qualities of the cutting surface. Simultaneously, the utility model can reduce the wear of the cutter during processing, thereby prolonging the service life of the cutter, reducing the production cost of an enterprise, improving the quality of products of the enterprise, and producing high economic benefits for the enterprise.

Description

The boring cutter of processing automobile compressor front and rear covers

Technical field

The utility model belongs to the Machining Technology field, relates in particular to a kind of boring cutter of processing automobile compressor front and rear covers.

Background technology

In the last few years, along with development of science and technology, machinery manufacturing industry also was more and more higher to the requirement of machining accuracy, generally adopted boring cutter to carry out bore hole such as the processing in the mandrel hole of housings such as gearbox, gear pump, the general first heavy boring of bore hole, back right boring.At present, add man-hour in right boring, the cutting tip of employed boring cutter mainly is polycrystalline diamond (PCD) composite sheet, its composite sheet is that polycrystalline diamond (PCD) layer and hard alloy layer form through the HTHP compacting, the point of a knife place of cutting tip is a straight line, the circular arc chamfering structure is not set, this structure machining accuracy of workpiece in working angles is lower, product quality can not adapt to the fast development of mechanical processing manufacturing industry, tool wear is comparatively serious in the process simultaneously, the service life of having reduced cutter.

The utility model content

The utility model provides a kind of boring cutter that can obviously improve workpiece to be machined precision, lifting product quality and prolong the processing automobile compressor front and rear covers of cutter life in order to solve weak point of the prior art.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: the boring cutter of processing automobile compressor front and rear covers, comprise cutter hub, and cutter hub front end one side is provided with cutting tip, and the point of a knife of described cutting tip is the circular arc chamfering structure.

Described circular arc chamfering radius is 0.2mm.

Adopt said structure, the beneficial effect that reaches has:

1, the point of a knife of cutting tip part is improved to the circular arc chamfering structure by the right angle chamfering structure, the precision that is cut workpiece improves greatly, qualities such as the fineness in cutting face also greatly promote, the wearing and tearing that can alleviate cutter simultaneously in process, the service life of prolongation cutter.

2. described circular arc chamfering radius is 0.3 ± 0.05mm, can farthest alleviate the wearing and tearing of cutter in the process, farthest improve the precision of workpiece to be machined.

In a word, the utility model is simple in structure, reasonable in design, easy to use, can promote the service life of stock-removing efficiency, prolongation cutting tip, the machining accuracy of raising workpiece, thereby reduce the production cost of enterprise, promote the quality of enterprise product, for enterprise creates higher economic benefit.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the enlarged drawing at A place among Fig. 2.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, the boring cutter of processing automobile compressor front and rear covers of the present utility model, comprise cutter hub 1, cutter hub 1 front end one side is provided with cutting tip, cutting tip comprises polycrystalline diamond (PCD) material layer 2 and hard alloy layer 3, and polycrystalline diamond (PCD) material layer 2 and hard alloy layer 3 are compressed to one, and hard alloy layer 3 is welded on the cutter hub 1, the point of a knife 4 of cutting tip is the circular arc chamfering structure, and this circular arc chamfering radius is 0.3 ± 0.05mm.

The employing circular arc chamfering structure of point of a knife 4 makes boring cutter of the present utility model when processing automobile compressor front and rear covers plane, can improve the service life of the quality of workpiece, the wearing and tearing that reduce cutter, prolongation cutter.

Claims

1. the boring cutter of processing automobile compressor front and rear covers comprises cutter hub, and cutter hub front end one side is provided with cutting tip, it is characterized in that: the point of a knife of described cutting tip is the circular arc chamfering structure.

2. the boring cutter of processing automobile compressor front and rear covers according to claim 1 is characterized in that: described circular arc chamfering radius is 0.3 ± 0.05mm.
