Abstract
The utility model discloses a piston compressor is high, and utensil is examined in measuring special use, carry out the location axle of fixing a position insert the piston pin hole on the support in with setting up including the support, still include measurement element, measurement element including be used for with location axle surface paste fit and with the high standard size of the location axle radius piston compressor of group highly to rule with be used for the amesdial that returns to zero and set up and detect the high error of piston compressor, not only can be fast convenient detecting piston product compression height, examining a compact structure moreover, the inspecting result accuracy is high.
Description
Technical field
The utility model relates to cubing field, particularly a kind of piston compression high detection appliance special for detecting.
Background technology
Piston compression is high refers to the distance of piston pin center to piston-top surface, compression height is the principal character of piston, it is the principal element affecting engine performance, due to the reason such as processing mode and equipment precision, the high overproof old problem being most of piston manufacturing enterprise and running into of compression, compression high detection is also essential items for inspection, with the bad measurement of general measurer, measuring accuracy can not ensure, needs design specialized cubing to measure.
Utility model content
In view of this, the utility model provides a kind of piston compression high detection appliance special for detecting, and not only can detect the compression of piston product is high quickly and easily, and detection tool structure is compact, assay degree of accuracy is high.
Piston compression high detection appliance special for detecting of the present utility model, comprise support and be arranged on locating shaft support inserting and positions in piston pin hole, also comprise measurement components, described measurement components comprises and to close out and with the height of locating shaft radius group piston compression high standard size to advising and arrange for making zero and detecting the clock gauge of piston compression high level error for being adjacent to locating shaft surface.
Further, also comprise micrometer fixing rack, described micrometer fixing rack is detachably arranged on support.
Further, micrometer fixing rack comprises cross bar and montant, and described cross bar can move up and down.
Further, support comprises base plate and side plate, and described locating shaft is fixedly installed on described side plate, is also provided with for the limited block to the high cross spacing of compression near described side plate.
The beneficial effects of the utility model: piston compression high detection appliance special for detecting of the present utility model, before detection, first by being highly adjacent to rule lower surface and locating shaft surface, by clock gauge contact with highly contact advising upper surface, by highly to rule along locating shaft axis oscillating, when clock gauge reading reaches maximum, clock gauge is made zero, the height value of now clock gauge zero graduation representative and piston compression high basic size, thus determine reduced size survey boundary value, during actual measurement product, locating shaft is inserted piston pin hole and realize location, clock gauge contact is contacted with piston upper surface, oscillating-piston, the full-scale reading of clock gauge and the high error amount of piston compression, this is fast easy to detect, and detection tool structure is compact, and inspection structural precision is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the utility model one-piece construction schematic diagram;
Fig. 2 is the utility model one-piece construction using state figure.
Embodiment
Fig. 1 is the utility model one-piece construction schematic diagram, Fig. 2 is the utility model one-piece construction using state figure, as shown in the figure: the piston compression high detection appliance special for detecting of the present embodiment, comprise support 1 and be arranged on the locating shaft 2 support 1 inserting and positions in piston pin hole, also comprise measurement components, described measurement components comprises and to close out and with the height of locating shaft 2 radius group piston compression high standard size to rule 3 with arrange for making zero and detect the clock gauge 4 of piston compression high level error for being adjacent to locating shaft 2 surface, rely on and highly the high basic size of piston compression is combined into rule 3 and locating shaft 2, highly piston compression high basic size is to the radius that the thickness of rule 3 adds locating shaft 2, when detecting, before detection, first by being highly adjacent to rule 3 lower surface and locating shaft 2 surface, by clock gauge 4 contact with highly rule 3 upper surface is contacted, by highly to rule 3 along locating shaft 2 axis oscillating, when clock gauge 4 reading reaches maximum, clock gauge 4 is made zero, the height value of now clock gauge 4 zero graduation representative and piston compression high basic size, thus determine reduced size survey boundary value, during actual measurement product, locating shaft 2 is inserted piston pin hole and realize location, clock gauge 4 contact is contacted with piston 7 upper surface, oscillating-piston, the full-scale reading of clock gauge 4 and the high error amount of piston compression, by locating shaft 2 as positioning element, and the simulation of locating shaft 2 center instead of piston pin center, and it is good that benchmark selects, and ensure that measuring accuracy, piston can rotate around locating shaft 2, and piston upper surface peak can be reflected by the flex point of clock gauge 4 pointer, and reading is directly perceived, structure is simple, and detection efficiency is high, and accuracy of detection is high, low cost of manufacture.
In the present embodiment, also comprise micrometer fixing rack 5, described micrometer fixing rack 5 is detachably arranged on support 1.
In the present embodiment, micrometer fixing rack 5 comprises cross bar 5-1 and montant 5-2, and described cross bar 5-1 can move up and down; Cross bar 5-1 is by anchor ear and be installed on montant 5-2 by tightening piece 5-3, and when needs move up and down, turn tightening piece 5-3 can realize.
In the present embodiment, support 1 comprises base plate 1-1 and side plate 1-2, and described locating shaft 2 is fixedly installed on described side plate, is also provided with for the limited block 6 to the high cross spacing of compression near described side plate.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
