Embodiment 1

[0018] Such as figure 1 , figure 2 , image 3 and Figure 4 The scroll compressor profile finishing tool shown has a shank 1 and a cutting edge composed of a side edge 2, an end edge 3 and a chip flute. The side edge 2 has a rake angle γ and a relief angle, and the rake angle γ is 8 degrees to 10 degrees; there are six side edges 2, and the helix angle β of the side edges 2 is 45 degrees; the back of the side edge 2 has a first back and a second back, the width b of the first back is 0.4 mm, and the first back angle α1 is 0.5 degrees; the second relief angle α2 is 18 degrees; the groove bottom helix angle ε of the chip flute is 30 degrees, such as Figure 5 Shown; The axial cutting angle θ of the end edge 3 grooves is 18 degrees. Due to the addition of a transition edge bevel and transition relief angle at the rear of the side edge cutting edge, the combination of small transition relief angle and large relief angle, and the width of the transition edge bevel is controll...

Embodiment 2

[0020] Such as figure 1 , figure 2 , image 3 and Figure 4 The scroll compressor profile finishing cutter shown has a blade and a shank 1 composed of a side edge 2, an end edge 3 and a chip flute. The side edge 2 has a rake angle γ and a relief angle, and the rake angle γ is 8 degrees to 10 degrees; there are six side edges 2, and the helix angle β of the side edges 2 is 45 degrees; the back of the side edge 2 has a first back and a second back, the width b of the first back is 0.5 mm, and the first back angle α1 is 3.5 degrees; the second clearance angle α2 is 20 degrees; the groove bottom helix angle ε of the chip flute is 30 degrees, such as Figure 5 Shown; the axial cutting angle θ of the end edge 3 grooves is 20 degrees. Other features are the same as in Example 1.

Abstract

The invention discloses a vortex compressor type linear finish machining tool, and relates to the technical field of mechanical machining. The vortex compressor type linear finish machining tool comprises a blade part consisting of lateral blades, an end blade and a chip containing groove, wherein each lateral blade is provided with a front angle gamma and a back angle; the six lateral blades are arranged; a spiral angle beta of each lateral blade is 45 degrees; a first back face and a second back face are arranged on the back face of the lateral blade; the width b of the first back face is 0.4-0.5mm; the first back angle alpha 1 is 0.5-3.5 degrees; the second back angle alpha 2 is 18-20 degrees; a spiral angle epsilon at the groove bottom of the chip containing groove is 30 degrees; and an axial digging angle theta of a groove of the end blade is 18-20 degrees. Compared with the prior art, the service life of the vortex compressor type linear finish machining tool disclosed by the invention is 5 times as much as that of a milling tool in the prior art, and the machining cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a tool used for machining scroll profiles of compressors. Background technique [0002] In the scroll compressor, the processing of the scroll profile of the movable and static scroll is a key process. The contour of the profile processing, the verticality of the side wall and the bottom surface, and the surface roughness are high. The quality directly determines the performance of the scroll compressor. There is a scroll compressor profile finishing tool, which comprises a shank and a blade, the blade is provided with four side edges along its own axial direction; the blade has a side The edge, the end edge and the chip flute, the side edge includes a rake angle and a relief angle, the angle of the rake angle is 8-10 degrees; the angle of the relief angle is 15-16 degrees. This type of compressor profile finishing has the following deficiencies during use: 1. The...
