Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0023] figure 1 It is the casing 7 of the scroll compressor, and the front end surface A of the casing 7 on the side of the orifice is a processed plane, and the multi-step inner hole near the orifice of the casing 7 needs to be processed;

[0024] The processing method of the inner hole of the casing is to use a fixture for processing the inner hole of the casing, such as Figure 2 to Figure 3 The jig for processing the inner hole of the casing includes a base 1 with a central hole, the base 1 is provided with a positioning tooth mouth and a plurality of circumferentially distributed stepped holes on one end surface; the other end surface of the base 1 is circumferentially distributed with Four guide rods 2, wear a pressure ring 3 at the front ends of the four guide rods, the pressure ring 3 is connected with the four guide rods 2 by four bolts respectively, the bol...

Abstract

The invention discloses a machine shell inner hole machining method, and relates to the technical field of machining. A machine shell inner hole machining clamp is used. The machine shell inner hole machining method comprises the following steps that A, a clamp is mounted, wherein a base of the machine shell inner hole machining clamp is fixed on a main shaft of a machine tool through a positioning tooth opening and a bolt penetrating through a plurality of stepped holes, so that an ejector rod driven by a hydraulic cylinder penetrates through a center hole of the main shaft to extend into thecenter hole of the base, and an ejector head is screwed at the end of the ejector rod through threads; B, a workpiece is loaded, wherein a machine shell is placed between the base and a pressing ring, so that a pin hole in the front end face of the machine shell is aligned with a positioning pin on the pressing ring; C, the hydraulic cylinder is started, so that the ejector rod drives the machine shell to move forward through the ejector head, and the front end face of the machine shell is connected with the pressing ring in a pressing mode; and D, the main shaft is started, so that the inner hole of the machine shell is machined through a tool on a tool tower of the machine tool. Compared with the prior art, the method can solve problem that the existing machining precision of the machine shell inner hole is poor.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method for the inner hole of a casing of a scroll compressor. Background technique [0002] The compressor casing is one of the important basic parts of the scroll compressor. It is made of aluminum alloy through precision casting. It has a circular inner hole, which plays the role of containing various components; therefore, the casing The dimensional accuracy and positional accuracy of inner hole processing are very high; at present, when the compressor casing is cast, three lateral positioning bosses are evenly distributed at the tail of the casing; The chuck is flat, and then the three lateral positioning bosses of the casing are clamped by the three claws on the chuck, and then the inner hole of the casing is processed by a tool. This clamping method has the following problems in the production process: due to the out-of-tolerance phenomenon in th...
