Abstract

The utility model provides an oil pump end clearance measuring fixture which comprises a pump body, a gear pair, a dial indicator, a square iron and a fastening screw. The gear pair is arranged in a first groove at the upper end of the pump body; a spacing between a second upper end face of the gear pair and a first upper end face of the pump body forms a clearance; the square iron and the dial indicator are fixed by the fastening screw in a matching mode; a flattened contact surface at the lower end of the square iron fits the first upper end face of the pump body; and the lower end of the dial indicator is in contact with the second upper end face. The oil pump end clearance measuring fixture provided by the utility model has the advantages of simple structure, convenient use, capability of quick product detection, non-site-specific feature, clear detection results, no need of intermediate calculations, short measurement assisting time and strong practicability.

Description

Tool is measured in the oil pump end clearance
Technical field
The utility model relates to the cubing technical field, relates in particular to a kind of oil pump end clearance and measures tool.
Background technology
The end clearance of oil pump gear joint and the pump housing determines an important parameter of end product quality, need carry out 100% by the assembly technology requirement and detect control, still, at present, tool is measured in existing oil pump end clearance, mostly complex structure, be subjected to the place space constraint, detect trouble.
The utility model content
The technical matters that (one) will solve
Problem to be solved in the utility model provides a kind of oil pump end clearance and measures tool, to overcome oil pump end clearance measurement jig structure complexity in the prior art, is subjected to the place space constraint, detects the defective of trouble.
(2) technical scheme
For solveing the technical problem, the utility model provides a kind of oil pump end clearance to measure tool, comprises the pump housing, gear pair, dial gauge, square iron and holds out against screw; Described gear pair is arranged in the first groove of described pump housing upper end; The spacing of the second upper surface of described gear pair and the first upper surface of the described pump housing forms the gap; Described square iron and described dial gauge are fixed with the described screw fit that holds out against; The first upper surface of the surface of contact that the lower end of described square iron polishes and the described pump housing fits; The lower end of described dial gauge contacts with described the second upper surface.
Further, described square iron below is provided with the second groove, and described dial gauge lower end falls in described the second groove.
Further, the described surface of contact surfaceness that polishes is Ra0.4mm.
(3) beneficial effect

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
To shown in Figure 5, tool is measured in a kind of oil pump of the present utility model end clearance, comprises the pump housing 1, gear pair 2, dial gauge 3, square iron 4 and holds out against screw 6 such as Fig. 1; Said gear pair 2 is arranged in the first groove 5 of the above-mentioned pump housing 1 upper end; The second upper surface 11 of said gear pair 2 forms gap 10 with the spacing of the first upper surface 9 of the above-mentioned pump housing 1; Above-mentioned square iron 4 is fixed with the above-mentioned screw 6 that holds out against of above-mentioned dial gauge 3 usefulness; The surface of contact 8 that the lower end of above-mentioned square iron 4 polishes fits with the first upper surface 9 of the above-mentioned pump housing 1; The lower end of above-mentioned dial gauge 3 contacts with above-mentioned the second upper surface 11.
Above-mentioned square iron 4 belows are provided with the second groove 7, and above-mentioned dial gauge 3 lower ends fall in above-mentioned the second groove 7.The above-mentioned surface of contact that polishes 8 surfacenesses are Ra0.4mm.
During use, as long as square iron 4 is placed to the pump housing 1 top, the surface of contact 8 that polishes and the first upper surface 9 fit, and the lower end of dial gauge 3 contacts the detection of the gap 10e that can carry out the first upper surface 9 and the second upper surface 11 with the second upper surface 11.
Tool is measured in oil pump of the present utility model end clearance, and is simple in structure, easy to use, can carry out fast detecting to product, not limited by the place, and testing result is very clear, does not need to carry out intermediate computations, and measurement is short, practical non-cutting time.
In sum, above-mentioned embodiment is not to be restricted embodiment of the present utility model, and the modification that all those skilled in the art carry out on the basis of flesh and blood of the present utility model or equivalent deformation are all at technology category of the present utility model.
