This utility model relates to a kind of depth of center hole cubing, belongs to workpiece sensing technical field.Technical scheme is: the end face of measured workpiece (5) is provided with centre bore (6), main body (1) is arranged on the top of measured workpiece, and main body (1) is hollow-core construction, surveys pin (2) coupling and is arranged on the inside of main body, lower end extends downwardly from, and extending area is mated in centrally disposed hole；The described side surveying pin (2) is provided with chute (7), and one end of screw (3) is vertically fixed in main body, and the other end is arranged in chute；The described top surveying pin is provided with step (4).This utility model is simple to operate, can promote the inspection for all types depth of center hole, it is possible to achieve on the basis of measured workpiece end face, completely attach to cubing, touch mode with hands and check the position of survey pin, check whether the degree of depth of centre bore exceedes tolerance very clear, measure the most conveniently.
Description
Technical field
This utility model relates to the special inspection that a kind of depth of center hole cubing, particularly workpiece centre hole depth carry out checking
Tool, belongs to workpiece sensing technical field.
Background technology
Centre bore is modal positioning datum in machining, and the depth of centre bore directly affects workpiece axial dimension
Precision.In current actual production, in order to ensure machining accuracy, the degree of depth of centre bore should have certain tolerance, centre bore
After machining, not having the good special instruments of inspection to carry out the degree of depth in hole, inspection center, artificial measurement there will be error.
Utility model content
This utility model purpose is to provide a kind of depth of center hole cubing, and inspection center's hole depth meets the model of manufacturing tolerance
Enclose, accurate quick in whole work process, simple to operate, solve problem present in background technology.
The technical solution of the utility model is:
A kind of depth of center hole cubing, comprises main body, surveys pin, screw, step, measured workpiece, centre bore and chute, described
The end face of measured workpiece is provided with centre bore, and main body is arranged on the top of measured workpiece, and main body is hollow-core construction, surveys pin coupling and sets
Putting the inside in main body, lower end extends downwardly from, and extending area is mated in centrally disposed hole；The described side surveying pin is provided with cunning
Groove, one end of screw is vertically fixed in main body, and the other end is arranged in chute；The described top surveying pin is provided with step.
The described bottom surveying pin extending area is cone, and the cone angle of circular cone is 60 degree.
The beneficial effects of the utility model are: simple to operate, can promote the inspection for all types depth of center hole, can
To realize on the basis of measured workpiece end face, completely attach to cubing, touch mode with hands and check the position of survey pin, check centre bore
The degree of depth whether to exceed tolerance very clear, it is the most convenient to measure.
Accompanying drawing explanation
Fig. 1 is this utility model cross-sectional view；
In figure: main body 1, survey pin 2, screw 3, step 4, measured workpiece 5, centre bore 6, chute 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
A kind of depth of center hole cubing, comprises main body 1, surveys pin 2, screw 3, step 4, measured workpiece 5, centre bore 6 and slide
Groove 7, the end face of described measured workpiece 5 is provided with centre bore 6, and main body 1 is arranged on the top of measured workpiece 5, and main body 1 is hollow knot
Structure, surveys pin 2 coupling and is arranged on the inside of main body 1, and lower end extends downwardly from, and extending area is mated in centrally disposed hole 6；Described survey
The side of pin 2 is provided with chute 7, and one end of screw 3 is vertically fixed in main body 1, and the other end is arranged in chute 7；Described main body 1
Top be provided with step 4, the top surveying pin 2 is positioned at step 4 or exceeds step 4.
The bottom of described survey pin 2 extending area is cone, and the cone angle of circular cone is 60 degree.
Survey pin 2 freely up and down to slide in main body 1, but can not deviate under the effect of screw 3.
When detection, first by measured workpiece 5 centre bore 6 upwards, it is disposed vertically, then this utility model is positioned tested work
On the end face of part 5 sturdy, now press survey pin 2, survey pin 2 extending area insert measured workpiece centre bore, make survey pin 2 extension
Bottom, position is in close contact with centre bore 6, for qualified within the upper surface of main body 1 is positioned at the step of survey pin 2, the most defective.
