Abstract

The utility model provides a detection device for concentricity and verticality of a crosshead body. In the prior art, the processing precision of the concentricity and the verticality can only be guaranteed by molds, machine tools and operators. Since no detection methods exist, overproof form and location tolerance is caused in assembling and a product needs to be returned to a machining shop for repairing. Sometimes, the product is beyond repair, so that a waste piece is produced. Therefore, the production schedule is influenced and comparatively large economic losses are caused. The utility model aims to solve the above problem. The detection device for concentricity and verticality of the crosshead body includes a manual angle grinder. The detection device for concentricity and verticality of the crosshead body is characterized in that two mutually-perpendicular dialgauges are fixed on an end of a dialgauge connecting rod; the dialgauge connecting rod is perpendicular to a detection tool connecting rod mutually and fixed with the detection tool connecting rod together; and an end of the detection tool connecting rod is fixed with a crosshead piston rod connecting threaded detection tool together. The detection device for concentricity and verticality of the crosshead body provided by the utility model has an advantage that the detection device for concentricity and verticality of the crosshead body can be used for detecting the concentricity and the verticality of the crosshead body at the same time; and through detecting work pieces, the appearance of batches of waste pieces is avoided, effective quality control in a machining process can be realized timely, the rejection rate is reduced and the economic performance is enhanced.

Description

The pick-up unit of crosshead body right alignment and verticality
Technical field
The utility model relates to a kind of pick-up unit, is a kind of pick-up unit that can detect simultaneously right alignment and the verticality of crosshead body specifically.
Background technology
Crosshead body in compressor, the right alignment precision prescribed of the verticality of its piston rod connecting thread and crosshead pin-and-hole and crawler shoe (crosshead body external diameter) is very high, add in process at machine, which is defective all will have influence on assembling, because crosshead body moves back and forth in middle body slideway, so guarantee that the crudy of crosshead body is most important.Without appliance special for detecting the time, verticality and right alignment can only lean on mold, lathe and operator to guarantee machining precision, because of without detection means, when assembling, because misoperation causes form and position tolerance overproof, the machine that also need return adds the workshop to be repaired, sometimes because repairing products waste occasionally, namely affect manufacturing schedule, caused again larger economic loss.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of pick-up unit that can detect simultaneously right alignment and the verticality of crosshead body.
The technical solution of the utility model is: comprise dial gauge, it is characterized in that: two orthogonal dial gauges are fixed at dial gauge connecting link one end, dial gauge connecting link and cubing connecting link are mutually vertical and be fixed together, and an end of cubing connecting link and crosshead piston bar connecting thread cubing are fixed together.
Crosshead piston bar connecting thread cubing is threaded with crosshead body and fits with the crosshead body upper surface, the cubing connecting link is inserted in end mandrel on crosshead piston bar connecting thread cubing, after dial gauge is installed, the pin-and-hole mandrel is rotated a week, recording indicator maximum and least count, both is poor, is the error of perpendicularity.The dial gauge contact crosshead body external diameter of vertical direction is rotated a week, record maximum and the least count of dial gauge, both differences are coaxiality error.
The beneficial effects of the utility model are: the utility model can detect right alignment and the verticality of crosshead body simultaneously, by the check to workpiece, can avoid the generation of waste product in batches, can in time add process to machine and carry out effective quality control, reduced rejection rate, increased economic efficiency.
