Description
Technical field
The utility model belongs to technical field of mechanical processing, is related to a kind of endoporus bottom back chipping validation checking tool.
Background technology
Certain cylindrical member, inside processes large and small stepped hole, to meet requirement, need to ensure the flatness of step with
And the validity of endoporus bottom back chipping.But currently, after completion of processing cylindrical member, there is no effective tools to the interior shape of macropore
Sharp corner back chipping validity is detected.
Invention content
Purpose of the utility model is to solve the interior shape points currently without effective tool to stepped hole in cylindrical member
Back chipping carries out the problem of validation checking at angle, proposes a kind of endoporus bottom back chipping validation checking tool, realizes to processing
The interior shape sharp corner back chipping of endoporus carries out validation checking.
The purpose of this utility model is achieved through the following technical solutions.
A kind of endoporus bottom back chipping validation checking tool, including clearance gauge, cylinder and handle；
Cylinder is cylindrical structure, and outer diameter is slightly less than part diameter macropores to be measured, make its when for measuring just
It fills in part macropore to be measured；Its bottom surface and side disc exact vertical；
Handle is for holding, convenient for being grasped when detection；
Connection relation：Handle is connect with cylinder using welding or integrated molding mode maintenance.
The course of work：
When detection, handle is caught, cylinder is filled in into part macropore to be measured bottom, clearance gauge is lain in from small bore end on cylinder,
It is then attempt to the gap being plunged between cylinder bottom surface end face and part macropore to be measured bottom, if clearance gauge cannot be filled in,
Part to be measured is pieces O.K.；Otherwise, part to be measured is unqualified.
Preferably, cylinder is process using wear-resistant hard material.
Advantageous effect
Prior art is compared, the utility model, which can quickly detect the endoporus bottom back chipping in the stepped hole machined, to be had
Effect property, has the effect of light, quick, simple in structure, easy-to-use；It reduces the requirement to testing staff, greatly improve
The efficiency of batch detection.
Description of the drawings
Fig. 1 is a kind of endoporus bottom back chipping validation checking tool construction schematic diagram of the utility model.
Fig. 2 is the status diagram being detected to part to be measured using Fig. 1 tools；
Reference numeral：1- cylinders；2- handles；3- clearance gauges；4- parts to be measured.
Specific implementation mode
Preferred embodiments of the present invention are described in detail with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of endoporus bottom back chipping validation checking tool, including clearance gauge 3, cylinder 1 and handle 2；
Cylinder 1 is cylindrical structure, and outer diameter is slightly less than 4 diameter macropores of part to be measured, keeps it rigid when for measuring
It fills in well in 4 macropore of part to be measured；Its bottom surface and side disc exact vertical；
Handle 2 is for holding, convenient for being grasped when detection；For rod part；In the present embodiment, handle is processed as cylinder；
Connection relation：Handle 2 is connect with cylinder 1 using welding or integrated molding mode maintenance.
The course of work
As shown in Fig. 2, when detection, handle 2 is caught, cylinder 1 is filled in into 4 macropore bottom of part to be measured, by clearance gauge 3 from small bore end
It lies on cylinder, is then attempt to the gap being plunged between 4 macropore bottom of 1 bottom surface end face of cylinder and part to be measured, if
Clearance gauge 3 cannot be filled in, then part 4 to be measured is pieces O.K.；Otherwise, part 4 to be measured is unqualified.
Cylinder 1 is process using wear-resistant hard material, and such as tool steel, copper, the present embodiment uses tool steel.
It is required according to 4 stepped hole machining tolerance of part to be measured, selects the clearance gauge 3 of appropriate size.
Although combining the embodiment that attached drawing describes the utility model, it will be apparent to those skilled in the art that
Without departing from the principle of this utility model, various modifications and improvements can be made, these also should be regarded as belonging to this reality
With novel protection domain.
