Abstract
The utility model relates to a detection fixture for detecting roughness of a valve face of an air cylinder body of a compressor. The detection fixture is characterized by comprising a base, an upright plate, a support shaft, a clamping disc and positioning pins, wherein the upright plate is fixedly arranged on the side edge of the base, and the support shaft is fixedly arranged in the middle of the upright plate. A screw segment is formed on the front end of the support shaft, and the clamping disc is coaxially arranged on the support shaft in threaded mode. The surface, on the same side with the support shaft, of the upright plate is fixedly provided with two positioning pins. The detection fixture is scientific and reasonable in structural design, carries out positioning through a positioning shaft and a crank shaft hole of a cylinder body to be detected, adopts the clamping disc to fasten, guarantees stability of workpieces, and simultaneously carries out positioning through adoption of the two positioning pins and an auxiliary hole on the end face of the cylinder body, and consequently achieves clamping positioning of the workpieces with high accuracy, is quick and convenient to clamp, and not easy to loosen, effectively guarantees detection accuracy, and meets detection requirements.
Description
Technical field
The utility model belongs to compresser cylinder cylinder body checkout gear field, particularly a kind of compresser cylinder cylinder body valve face roughness measurement anchor clamps.
Background technology
For the SC type compressor of being commonly used on the refrigerator, the structure of its cylinder block is comparatively complicated, cylinder body need to be installed with parts such as bent axle, piston, valve blocks and cooperate, end face at cylinder body is shaped with crankshaft hole, be shaped with piston hole at the cylinder body valve face, the central shaft of crankshaft hole and piston hole is plumbness.The cylinder body requirement on machining accuracy is high, and the processing dimension at each position of cylinder body all need guarantee could satisfy the requirement with the accurate assembling of miscellaneous part within the error range of regulation.Particularly the cylinder body valve face need to satisfy the roughness requirement, and in the roughness measurement process, it is stable that workpiece need keep, and can not produce vibration, to guarantee accuracy of detection.And owing in process, need each batch products is carried out sampling Detection, so the testing amount is larger.At present, owing to also do not detect valve face roughness special fixture.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of clamping reliable and stable, can improve the compresser cylinder cylinder body valve face roughness measurement anchor clamps of accuracy of detection and detection efficiency.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of compresser cylinder cylinder body valve face roughness measurement anchor clamps, it is characterized in that: consisted of by base, riser, back shaft, chuck and alignment pin, side at base is fixedly mounted with described riser, level is fixedly mounted with described back shaft at the middle part of this riser, front end at this back shaft is shaped with thread segment, the chuck coaxial threaded is installed on the back shaft, is fixedly mounted with two described alignment pins on the surface of riser and back shaft homonymy.
Advantage of the present utility model and good effect are:
The utility model scientific structure design is reasonable, position by locating shaft and tested cylinder crankshaft hole, and adopt chuck fastening, guarantee workpiece stability, also adopt simultaneously the fabrication hole of two alignment pins and cylinder body end face to position, thereby realize the high accuracy clamping location of workpiece, clamping is quick, be difficult for becoming flexible, effectively guarantee accuracy of detection, satisfy testing requirement.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of compresser cylinder cylinder body valve face roughness measurement anchor clamps, it is made of base 5, riser 4, back shaft 2, chuck 1 and alignment pin 3, side at base is fixedly mounted with described riser, level is fixedly mounted with described back shaft at the middle part of this riser, front end at this back shaft is shaped with thread segment, the chuck coaxial threaded is installed on the back shaft, is fixedly mounted with two described alignment pins on the surface of riser and back shaft homonymy.
The operation principle of this compresser cylinder cylinder body valve face roughness measurement anchor clamps is:
Workpiece is sleeved on the locating shaft, position by locating shaft and tested cylinder crankshaft hole, it is fastening to adopt chuck that workpiece is carried out again, and guarantees workpiece stability, also adopt simultaneously the fabrication hole of two alignment pins and cylinder body end face to position, thereby realize the high accuracy clamping location of workpiece.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
