Abstract
The utility model discloses a detection device for perpendicularity of an end surface of a piston of a compressor, which comprises an operation platform and a gauge frame fixed length measuring apparatus. A piston fixing frame, a piston axial block and a gauge frame are respectively disposed on the operation platform, the piston fixing frame and the gauge frame are respectively disposed on two sides of the piston fixing frame, a piston fixing groove is arranged on the piston fixing frame, and a piston axis center positioning head is disposed on one side, which faces to the piston fixing frame, of the piston axial block and is rightly abutted to an axial line of a piston to be measured when the piston to be measured is arranged in the piston fixing groove. A measuring head of the gauge frame fixed length measuring apparatus is arranged on one end surface of the piston to be measured, and the distance between the measuring head and the axial line of the piston to be measured is 0.5*R to 0.95*R, wherein the R is the radius of the piston to be measured. The perpendicularity of the end surface of the piston is variation of reading of the length measuring apparatus when the piston to be measured rotates, and accordingly, the detection device has the advantages of convenience in operation and high detection precision, and can adapt to requirements of batch production of compressors.
Description
Technical field
The utility model relates to a kind of pick-up unit of compressor of air conditioner piston end surface verticality, and especially a kind of pick-up unit of automobile air conditioner compressor piston end surface verticality belongs to compressor of air conditioner manufacturing technology field.
Background technology
Existing automobile air conditioner compressor adopts the sloping plate type vehicle compressor of air conditioner mostly, and piston two ends of sloping plate type vehicle compressor of air conditioner are cylindrical shape, and the centre is the swash plate socket, is provided with ball-and-socket in two sides of swash plate socket.Compressor piston moves reciprocatingly in front and rear cylinder, finishes that residual gas expands in the cylinder, air-breathing, compression, four processes of exhaust.And the error of perpendicularity of two end faces of piston and axial line will be directly connected to the clearance volume in the compressor cylinder on the one hand, thereby influence the work efficiency of compressor; On the other hand, if the error of perpendicularity is excessive, the piston phenomenon of taking blame for others can take place also, cause the damage to compressor; Again on the one hand, therefore the reference plane when two end faces of piston are the processing ball-and-socket, if the verticality of two end faces of piston and axial line is bad, also can influence the machining precision of ball-and-socket, finally influences the product quality of compressor.
At present, the detection of the verticality of two end faces of piston and axial line is generally carried out on three-coordinate instrument, but this detection method exists operation inconvenience, the not high deficiency of accuracy of detection, can not adapt to batch production requirement.
The utility model content
At above-mentioned situation, the problem that the utility model quasi-solution is determined provides a kind of pick-up unit of easy to operate, compressor piston end face squareness that accuracy of detection is high, to adapt to the compressor batch production requirement.
For achieving the above object, the utility model has adopted following technical scheme: a kind of pick-up unit of compressor piston end face squareness, it comprises worktable, on described worktable, be provided with piston fixed mount, piston axial stop and dial framework, at described piston fixed mount and dial framework respectively in two sides of piston fixed mount; Described piston fixed mount is provided with the piston fixed groove; Described piston axial stop is provided with the piston axes positioning head towards a side of piston fixed mount, the piston of surveying in the piston fixed groove time, described piston axes positioning head just in time withstands on the axial line of the piston of surveying; Described dial framework regular length measuring instrument, the measuring head of described length measuring instrument are on an end face of survey piston, and the radius of setting the piston of surveying is R, and then measuring head is that 0.5R is to 0.95R to the distance of axial line.
Described piston axes positioning head is a semisphere.Described piston fixed groove is the V font.Described length measuring instrument is a dial gauge
Adopt said structure, because the piston fixed mount of the pick-up unit of compressor piston end face squareness of the present utility model is provided with the piston fixed groove, therefore the survey piston can be located, guarantee that described piston axes positioning head just in time withstands on the axial line of the piston of surveying, the measuring head that also guarantees simultaneously length measuring instrument is that 0.5R is to 0.95R to the distance of axial line.Like this, by rotating the piston of surveying, the reading of length measuring instrument changes the verticality that is piston end surface.Therefore, the pick-up unit of compressor piston end face squareness of the present utility model has the characteristics easy to operate, that accuracy of detection is high, can adapt to the compressor batch production requirement.Be 70.7 millimeters the piston of being surveyed as being 32 millimeters, length overall for external diameter, its verticality will be controlled at: to the distance of axial line during at 0.95R, the number of length measuring instrument changes and is not more than 0.02 millimeter at measuring head.
Here the biend that need to prove piston is generally used greater than the about 4 times cutter processing of washing one's face of piston diameter on the drum type favourable turn, therefore process the back piston end face and do not have convexity or concave, therefore can measure the verticality of piston end surface with the method for the jerk value of above measurement piston.
