The invention discloses a centering fixture, and relates to the technical field of machining process equipment manufacture. The centering fixture comprises a base, wherein a guide hole is formed in one end of the base; a positioning mandrel and a positioning expansion sleeve nested on the positioning mandrel are arranged on the guide hole; a cylinder is arranged at the other end of the base; and a piston rod of the cylinder sequentially penetrates through the guide hole of the base and the positioning mandrel to be connected with the positioning expansion sleeve. Compared with the prior art, the centering fixture can rapidly, accurately and automatically perform centering correction on a compressor casing, and the part clamping efficiency is improved.
Description
Technical field
The present invention relates to mechanical processing technique equipment manufacturing technology field, especially a kind of device for compressor case clamping.
Background technology
Compressor case is one of basic components important in screw compressor, and the columnar housing of its tool, is cast by precision by aluminium alloy, plays a part to support and containing various parts; Dimensional accuracy and position accuracy demand to the processing of compressor case endoporus are high; Conventionally be first to adopt three-jaw chuck to carry out clamping to compressor case to the processing method of compressor case endoporus, proofread and correct behind compressor case end face and endoporus center, then compressor case is processed.There is following deficiency in the method at this correction end face and endoporus center: the correction accuracy of end face and endoporus is poor, and the time is long in process of production, and clamping efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of centralizer for compressor case clamping, and it can be fast, accurately to the compressor case correction of automatically feeling relieved, and improves parts fixation efficiency.
Technical scheme provided by the invention is: this centralizer comprises that one end is provided with the base of pilot hole, and described pilot hole is provided with positioning core axle and is sleeved on the location expansion set on described positioning core axle; The other end of described base is provided with cylinder, and the described pilot hole that the piston rod of described cylinder installed described base is successively connected with described location expansion set with described positioning core axle.
In above-mentioned centralizer technical scheme, technical scheme can also be more specifically: described positioning core axle has the mandrel portion of the large cone in the little rear end of front end, the end face location division of cylindrical guide part and the described mandrel portion of link and described guide part, described positioning core axle is inserted on described pilot hole by its guide part.
Further, described positioning expander cover has the conical bore corresponding with described mandrel portion, and described location expansion set is sleeved in described mandrel portion by its conical bore; Put and have many openings and be staggered spaced opening towards the second distending groove backward towards the first distending groove forward and many and described the first distending groove at described positioning expander.
Further, between the end face location division of described positioning core axle and described location expansion set, be provided with cushion pad.
Further, described location expansion set is coaxial setting with described positioning core axle.
The front end of indication of the present invention is the right direction in piston rod end.
Owing to having adopted technique scheme, compared with prior art, the beneficial effect having is in the present invention:
Owing to centralizer being installed on the platform of lathe, first compressor case is sleeved on to positioning expander and puts, start cylinder, positioning core axle will be located expansion set distending under the driving of cylinder, and the correction of automatically feeling relieved improves parts fixation efficiency.
