specific Embodiment

[0025] The A positioning hole 2011 is a stepped hole with the big end on the top, the A bearing 204 is arranged in the big end of the stepped hole, and is against the stepped surface; the B positioning hole 2021 is a stepped hole with the big end on the bottom, so The B bearing 205 is arranged in the big end of the stepped hole and is against the stepped surface. The handle 203 is covered with a positioning sleeve 207, and the two ends of the positioning sleeve 207 are respectively inserted into the small ends of the A positioning hole 2011 and the B positioning hole 2021 to offset the inner ring of the A bearing 204 and the inner ring of the B bearing 205. ; The A bearing 204 and the B bearing 205 are both deep groove ball bearings. The end face of the bearing cooperates with the stepped face to withstand greater axial load and prolong the service life of the bearing. At the same time, it prevents the bearing from being displaced or directly separated from the positioning hol...

Abstract

The invention discloses equipment used for finish machining of a cylinder hole in a car air conditioner compressor shell. The equipment comprises a drilling machine, a combination tool is mounted on aspindle box of the drilling machine, and comprises a tool frame and a cylindrical box body, the tool frame comprises a pressure bearing plate A and a pressure bearing plate B, the tool frame is sleeved with the cylindrical box body, the cylindrical box body is fixedly connected with the pressure bearing plate A and the pressure bearing plate B, a set of positioning holes A are formed in the pressure bearing plate A, a positioning hole B is formed in the position, below each positioning hole A, of the pressure bearing plate B, each positioning hole A and the positioning hole B below the positioning hole A form a positioning hole set, a tool handle is assembled on each positioning hole set, the lower end of each tool handle is connected with a reamer, the combination tool comprises a transmission shaft with the upper end connected with a spindle of the drilling machine, a driving gear is mounted on the lower end of the transmission shaft, and the upper end of the tool handle is providedwith a driven gear engaged with the driving gear. According to the equipment, the cylinder hole in the car air conditioner compressor shell is subjected to finish machining, machining precision meeting the requirements can be achieved, and machining efficiency is high.

Description

technical field [0001] The invention relates to the production equipment of the automobile air-conditioning compressor, in particular to the equipment for finishing the cylinder hole on the housing of the automobile air-conditioning compressor. Background technique [0002] The automobile air conditioning system is one of the six major assemblies of the automobile, among which the air conditioning compressor is the core component of the air conditioning system and the heart of the automobile air conditioning refrigeration system. There are cylinder holes on the car air-conditioning compressor housing, usually in the form of 5 holes and 7 holes, which are evenly distributed on the same circumference. Since the cylinder holes require high processing accuracy (for example, a compressor shell processed by our company, the concentricity of each cylinder hole is required to be ≤0.2mm, and the verticality of a single cylinder hole is required to be ≤0.05mm), so it needs to be proce...
