The utility model discloses utilizing the percentage table to the dabber and the detection of being surveyed the part reference surface, reaching the result of the size of examining indirectly, the dabber has direction and positioning action, has avoided slide caliper rule to detect positioning error and the steering error who exists, effectively solved slide caliper rule detect on slippery ground, take not positive phenomenon, the easy operation convenience has improved the detection precision.
Description
Technical field
The utility model relates to a kind of device detected for accessory size, being specifically related to a kind of device for detecting shoulder hole depth dimensions, belonging to parts measurement apparatus field.
Background technology
To in the measuring process of parts size precision, usually relate to the part with shoulder hole, the mode that the measurement of shoulder hole depth dimensions often adopts uses slide calliper rule directly to measure, directly with kind of calliper easily occur on slippery ground, take not the phenomenon such as just, troublesome poeration, makes measurement data have error; And slide calliper rule detection exists positioning error and steering error, accuracy of measurement is not high, and length consuming time, efficiency are low, thus have impact on overall inspection progress.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of device for detecting shoulder hole depth dimensions, have self-locating function, accuracy of measurement is high, simple to operation.
The purpose of this utility model is achieved through the following technical solutions:
A kind of device for detecting shoulder hole depth dimensions, comprise dial gauge and base plate, also comprise and be vertically arranged on stair-stepping mandrel on base plate, described dial gauge is arranged on the top of mandrel, described mandrel upper end is measurement section, lower end is guide part, the external diameter of described measurement section and guide part is basic hole system clearance fit with the endoporus of tested part respectively, the external diameter of described measurement section is less than the external diameter formation limited step of guide part, described limited step coordinates with the step surface of the ladder endoporus of tested part, the height of described measurement section is consistent with tested design size, the top end face of measurement section is the reference field measured.
Preferably, described base plate is vertically provided with column, described column upper end is provided with a crossbeam, and described dial gauge is fixedly installed on the end of described crossbeam.
Preferably, described column is provided with sleeve, described crossbeam is fixed on sleeve.Sleeve can rotate around column, facilitates dial gauge to move and detects, and structure is simple, easy to operate.
Preferably, described column is telescopic structure, and its flexible place is provided with lock-screw.The height of column can adjust according to the part of practice examining, and after adjustment, practical lock-screw is locked, convenient and practical, simple to operate.
The beneficial effects of the utility model: compared with prior art, the utility model uses mandrel, by the detection using slide calliper rule direct-detection to change in prior art to utilize dial gauge to mandrel and tested part reference field, indirectly draw the result that institute's dipping is very little, efficiently solve slide calliper rule detect on slippery ground, take not positive phenomenon, simple to operation; When detecting, mandrel has guiding and positioning action, eliminates slide calliper rule and detects the positioning error and steering error that exist, improve accuracy of detection.
