Orbiting scroll structure capable of accurately positioning and work fixture thereof

Abstract

The invention provides an orbiting scroll structure capable of accurately positioning and a work fixture thereof. The orbiting scroll structure comprises an orbiting scroll, and a plurality of grooves are formed in the upper surface of the edge of the periphery of the orbiting scroll. Three grooves are formed, and are distributed at the periphery of the orbiting scroll uniformly. The work fixture of the orbiting scroll structure comprises a precise connecting plate, a precise support base, a basic shaft super precise positioning reference block, a plane positioning precise reference block, a super precise main alignment pin, a super precise auxiliary alignment pin, an auxiliary alignment pin and a clamping mechanism; according to the orbiting scroll structure and the work fixture thereof, an orbiting scroll bearing hole and an auxiliary hole as well as a reverse side processed plane are utilized for super precision positioning, and meanwhile, three grooves are formed in the upper surfaces of the edge of the periphery of the orbiting scroll and are used as acting points for pressing force, so that the traditional positioning manner and clamping manner are changed, cutting stress to a workpiece caused by a cutter during processing is completely offset, and the problems of poor positioning accuracy and large repetitive position error which are caused by different standards are solved.

Description

technical field [0001] The invention relates to the field of scroll compressor processing, in particular to a movable scroll structure capable of precise positioning and a fixture thereof. Background technique [0002] The processing of the movable scroll and the fixed scroll in the scroll compressor has always been a technical problem. The domestic existing technology has not been able to solve the problems of poor positioning accuracy, unstable pressing force and poor repeat positioning accuracy; especially The movable scroll, because of its appearance, almost all positions need to be processed, and the clamping position is very limited during processing, which makes processing more difficult. [0003] The main problem of the existing processing technology of the movable scroll is that the positioning reference and the detection reference are not uniform, and the positioning reference and the assembly reference are not uniform, resulting in poor positioning accuracy during...

[0002] The processing of the movable scroll and the fixed scroll in the scroll compressor has always been a technical problem. The domestic existing technology has not been able to solve the problems of poor positioning accuracy, unstable pressing force and poor repeat positioning accuracy; especially The movable scroll, because of its appearance, almost all positions need to be processed, the clamping position is very limited during processing, and the processing is more difficult

[0003] The main problem of the existing processing technology of the movable scroll is that the positioning reference and the detection reference are not uniform, and the positioning reference and the assembly reference are not uniform, resulting in poor positioning accuracy during processing; The expansion and positioning of the bearing hole at the bottom of the turntable or the external force clamping of the outer circumference of the movable scroll, because the clamping force for positioning depends entirely on the radial tension force, and the main force on the movable scroll during processing It is the axial cutting force, which causes over-defined interference between the clamping method and the positioning method of the fixture. It is difficult to completely offset the positioning deviation caused by the cutting stress during processing, which results in poor repeat positioning accuracy and unstable clamping force. ,The problem
