Abstract
The invention provides a threaded holes position accuracy comprehensive testing fixture which comprises a testing fixture body with a flat board. The testing fixture body is provided with two location holes which are arranged right opposite to datum holes in a workpiece to be tested. The testing fixture also comprises locating pins used for fixing the location holes in the testing fixture body and the datum holes in the workpiece to be tested. The testing fixture body is also provided with several inspection holes penetrating through the testing fixture body. Each inspection hole is manufactured according to design positions of threaded holes in the workpiece to be tested. Each threaded measuring bar respectively passes through the corresponding inspection hole in the testing fixture body to be screwed into the corresponding threaded hole in the workpiece to be tested so as to finish position accuracy detection of the threaded holes. The comprehensive testing fixture is arranged on the upper entrance face of the workpiece. After the testing fixture and the workpiece are localized through locating pins, the threaded measuring bars are screwed into the threaded holes through the inspection holes in the body, thus completing position accuracy detection of the threaded holes.
Description
Technical field
The invention belongs to field of machining, relate to a kind of threaded hole position comprehensive check tool.
Background technology
Threaded hole generally only plays the effect of connection, the accordance of its processing is easy to be left in the basket, along with improving constantly that product quality is required, in industry, progressively the measurement of double thread is analyzed, the measurement of threaded hole position at present mainly concentrates on and utilizes three-dimensional coordinates measurement, but three coordinate measuring machine, due to the restriction of gauge head, can not bring into play for the measurement of threaded hole the advantage that its precision is high.
Most screw thread hole position all adopts maximum material principle in requiring, and traditional measurement method cannot be by maximum solid effect compensating in testing result, conventionally be similar to replacement by the method that detects thread Pilot hole or screw thread path, central diameter size that cannot double thread is measured, the uncertainty of measuring is relatively large, cause the qualification rate of part lower, and checkability is low.
Summary of the invention
The object of the invention is to overcome prior art defect, a kind of simple to operate, threaded hole position comprehensive check tool that checkability is high is provided.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of threaded hole position comprehensive check tool, comprise the cubing body that plate face is smooth, on cubing body, offer two with workpiece to be checked on the just right pilot hole of datum hole, also comprise the register pin for datum hole on pilot hole and workpiece to be checked on fixing cubing body, on cubing body, also offer the detection hole that several run through cubing body, each hole of detecting makes according to the design attitude of workpiece upper screwed hole to be checked, each screw thread length bar is screwed in to the position degree that completes double thread hole in the threaded hole of workpiece to be checked through the detection hole on cubing body respectively and detect.
On described cubing body, each detection in hole is provided with detection lining, and screw thread length bar runs through cubing body through detecting lining.
Described screw thread length bar pars intermedia diameter is greater than two ends diameter, the screw thread that the one small end setting of screw thread length bar is mated with workpiece threaded hole.
One of described register pin is rhombus pin, and one is straight pin.
Described cubing body is not offered the position in detection hole and is emptied.
Described rhombus plunger portion is rhombus, and bottom is cylindrical, and rhombus pin cylindrical side wall is provided with opening, and screw stretches in this opening and fixes locked to rhombus pin and cubing body through cubing body.
When threaded hole system on actinal surface on gear box casing is detected, comprehensive check tool is placed on workpiece on actinal surface,, by behind cubing and workpiece location screw thread length bar is screwed in the threaded hole of workpiece by the detection hole on body by register pin, the position degree that has completed double thread hole detects.If screw thread length bar can screw in threaded hole explanation threaded hole, position dimension is qualified, illustrates that threaded hole size has deviation if cannot screw in, and this cubing is simple, convenient can complete detection online, and checkability is high; Cubing of the same race can be designed many cover multi-series comprehensive check tools, and the threaded hole system that is applied to various workpieces is detected, practical, the difficult problem can quick solution threaded hole position detecting.
