Abstract
The utility model provides a gauge for a crankshaft end face connection hole location degree. The gauge can detect the size of the crankshaft end face connection hole and the position relationship of the connection hole relative to positioning raised points. The detection is quick, simple and accurate. The gauge comprises a template and positioning bars. The gauge is characterized in that a detection through hole and a positioning through hole which are matched with a crankshaft connection hole to be detected and a positioning raised point to be detected are arranged on the template, one of two groups of positioning bars is no-go gauges, the other group is go gauges and the number of each of groups of positioning bars is two.
Description
Technical field
The utility model relates to crankshaft of diesel engine Components field, is specifically related to a kind of crankshaft end-face detecting tool for position degree of connection hole.
Background technology
The crankshaft of diesel engine end face has several take the crankshaft end-face center as the symmetrical connecting hole of benchmark, and the crankshaft end-face center is provided with positioning convex.The crankshaft end-face connecting hole is except need detection aperture size, simultaneously, need to detect the position relationship of connecting hole and positioning convex, traditional vernier caliper detects the centre distance that can only detect two symmetrical connecting holes, can not detect the position relationship between two connecting holes, namely whether symmetrical centered by the end face of location, if detect with three-dimensional detection machine, testing process is complicated, and length expends time in.
Summary of the invention
For the problems referred to above, the utility model provides a kind of crankshaft end-face detecting tool for position degree of connection hole, and it can check crankshaft end-face connecting hole size, and connecting hole is with respect to the position relationship of positioning convex, testing process fast, simple, accurately.
Its technical scheme is such, a kind of crankshaft end-face detecting tool for position degree of connection hole, it comprises template, locating bar, it is characterized in that: have the detection through hole and the positioning through hole that adapt with bent axle connecting hole to be detected, positioning convex on described template, described locating bar has two groups, one group is drift, and one group is no-go gage, two every group.
It is further characterized in that:
Every group of described locating bar has one to be the yi word pattern taper pin with chamfered edge;
Described taper pin comprises that handle portion, stop portion, slide assembling part divide and the test section, the upper limit or its lower limit of corresponding its processing criterion of bent axle connecting hole to be checked of described taper pin test section major diameter, described locating bar slide assembling part divide and belong to sliding accessory with described template detection through hole and connect;
When described taper pin uses, its yi word pattern major axis is perpendicular to two pin lines of centres, and its stop portion of described taper pin is positioned at described two pin lines of centres and is provided with recessed seam;
Described detection through hole equates with the standard value of connecting hole centre distance with described positioning through hole centre distance and bent axle positioning convex to be detected.
After adopting the utility model structure, its beneficial effect is: template is set in bent axle positioning convex to be detected by pilot hole and locates, its template bottom surface and crankshaft end-face to be detected are fitted, and rotation template makes it detect through hole corresponding with bent axle connecting hole to be detected, insert respectively one group of locating bar and two groups, if one group and two groups of locating bar can insert, bent axle connecting hole size is qualified, position degree is good, otherwise, as long as have a locating bar not insert, process defective; With the chamfered edge taper pin, larger plug-in mounting space is arranged, is easy to install, simultaneously, the yi word pattern major axis vertical with two pin lines of centres, guarantee its connecting hole of bent axle to be measured its centered by positioning convex, symmetrical.Testing process fast, simply, accurately.
