Clamp for machining molded line of scroll plate

Abstract

The invention discloses a clamp for machining a molded line of a scroll plate, and relates to the technical field of equipment of mechanical machining processes. The clamp comprises a base of which the top surface is provided with a middle hole, wherein a lower end plate is fixedly connected to the bottom of the base; at least three pressing arms are distributed at the periphery of the middle hole in the top surface of the base and are connected to the base by hinged shafts; each pressing arm is hinged with a pressing arm driving cylinder; positioning pins are arranged on the top surface of the base; each pressing arm is hinged to a lug plate which extrudes out of a connecting ring; and the connecting rings are sleeved outside the upper end of the base and are fixedly connected with the base by bolts. Compared with the prior art, the clamp has the advantage that the scroll plate is clamped on the vertical machining center to be subjected to the machining of the molded line, so that the surface roughness, profile tolerance and dimensional accuracy of the molded line can meet the design requirement, the quality is ensured, and the production cost is saved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a fixture used for processing the profile line of a scroll disk of a scroll compressor. Background technique [0002] The core component of a scroll compressor is a scroll, which has an end plate and a scroll wall on it. The compression of the gas by the scroll compressor is realized by the movement of the sealing line of the scroll wall of the two scrolls from the outside to the inside when the two scrolls meshing with each other move relative to each other. Therefore, the manufacturing accuracy of the scroll profile directly affects the working performance of the scroll compressor. The processing of the scroll profile has particularly high requirements for equipment. In the early days, most people processed scrolls on special processing equipment. and processing costs are extremely expensive. In recent years, with the development of CNC machining technology, esp...

Therefore, the manufacturing accuracy of the scroll profile directly affects the working performance of the scroll compressor. The processing of the scroll profile has particularly high requirements for equipment. In the early days, people processed scrolls mostly on special processing equipment. and processing costs are extremely expensive

In recent years, with the development of numerical control machining technology, especially the improvement of the precision and performance of machining centers, it has become possible to process the scroll profile with vertical machining center equipment, but there is no suitable method for scroll Clamping fixtures on vertical machining centers for convenience and quality assurance
