Detailed Description

The following description of the embodiments refers to the accompanying drawings, which are included to illustrate specific embodiments in which the invention may be practiced.

As shown in fig. 3 and 4, the embodiment discloses a cutter for machining a front cylinder cover of a scroll compressor, the cutter for machining the front cylinder cover of the scroll compressor comprises a cutter body 1 and a plurality of blades 2, a water outlet hole 11 is formed in the inner side of the cutter body 1, both sides of the cutter body 1 are provided with inwards concave mounting grooves, the blades 2 are fixedly embedded in the mounting grooves, the cutter body 1 comprises a cutter handle 13 and a cutter tip 12, two ends of the cutter handle 13 are respectively provided with a connecting end 132 and a tail end 131, the cutter tip 12 is connected to the connecting end 132, the water outlet hole 11 extends to the connecting end 132 from the tail end 131 along the length direction of the cutter body 1, and an orifice of the water outlet hole 11 is formed in a side surface and.

A cutter for processing cylinder cap before scroll compressor is adding man-hour, and blade 2 will be used for can cutting, and cutter body 1 goes out water to the place ahead through the apopore 11 of positive side, adds man-hour cutting fluid from apopore 11 blowout and flow to blade 2, can effectual cooling cutter, plays the effect that reduces cutter wearing and tearing, extension cutter life. Meanwhile, when a small-aperture solid hole is machined by the traditional cutter center water outlet structure, the cutter is easy to break when the cutter is machined due to the fact that the thickness of the cutter tip is small, the water outlet hole 11 of the cutter is formed in the front side edge of the cutter, water is discharged forwards, and risks of machining the cutter are greatly reduced. Wherein the blade 2 is welded with the cutter body 1.

The two sides of the tool body 1 are provided with chip grooves 14, and the chip grooves 14 extend from one end of the tool nose 12 far away from the tool shank 13 to the outer surface of the tool shank 13 along the direction close to the connecting end 132. When the blade 2 arranged on the tool nose 12 is used for cutting, the processed aluminum scraps are discharged to the outside along the scrap discharge groove 14, so that the risk that the aluminum scraps are remained on a processing surface and scratch the processing surface is effectively avoided, and the processing precision of the tool for processing the front cylinder cover of the scroll compressor is greatly improved.

In the present embodiment, the number of the water outlet holes 11 is two, and the two water outlet holes 11 are respectively communicated with the two chip grooves 14. The two water outlet holes 11 and the two chip grooves 14 are respectively positioned at two sides of the cutter body 1, the cutter is designed to discharge water from the side surface to the right front, the rigidity of the cutter can be ensured, the water discharging function of the cutter can be kept, aluminum chips can be smoothly discharged and cooled, and the risk of processing broken cutters and scraping processed surfaces by the aluminum chips is greatly reduced.

A plurality of blades 2 are respectively welded on both sides of the knife tip 12. In the machining process, the two sides of the tool nose 12 are simultaneously subjected to machining stress, and the machining precision of the tool for machining the front cylinder cover of the scroll compressor is further improved. A plurality of blades 2 may also be welded to both sides of the connecting end 132 for machining the outer edges of the anti-rotation pin holes. In this embodiment, the number of the blades 2 is four, two blades 2 are located on both sides of the tip 12 away from the end of the connecting end 132, and the other two blades 2 are welded on both sides of the connecting end 132.

The chip groove 14 comprises a straight groove section 141 and a guide groove section 142 which are communicated with each other, the straight groove section 141 is positioned on the tool nose 12, and the guide groove section 142 is positioned on the tool shank 13. Blade 2 is at the cutting in-process, and the aluminium bits will be processed in straight flute section 141, derives to the outside through guide groove section 142 at last, has guaranteed discharging smoothly of aluminium bits, has effectively avoided the aluminium bits to produce and has piled up the phenomenon, has improved the machining precision that is used for processing the cutter of scroll compressor front cylinder cap greatly.

The tool body 1 and the blade 2 are made of PCD materials. The material of cutter is the PCD material, can guarantee that the processing of preventing revolving the pinhole can reach the roughness requirement of product drawing. Wherein the knife handle 13 and the knife tip 12 are integrally formed. The whole body of the cutter body 1 is made of hard alloy, so that the stability of the cutter is ensured.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
