Background technology
In the center distance measurement technical field of hole, mostly adopt the positioning element of register pin as the centre distance cubing.At present, the register pin that is used for the centre distance cubing mainly contains and sells directly to households and two kinds of elasticity taper pins.If using, the register pin of centre distance cubing sells directly to households, because measured hole self has certain tolerance, hole value with a collection of workpiece there are differences, when direct selling enters tested gaging hole, owing to causing to sell directly to households, the difference of tested gaging hole has different gaps with measured hole, and these gap widths can be brought into measured value, and the result who measures is impacted.If the register pin of centre distance cubing uses the elasticity taper pin, position point is by the aperture of verify, this structure can be eliminated the influence of interporal lacuna to measuring, but because there is chamfering in the aperture of measured hole, aperture chamfering with a collection of workpiece there are differences, when direct selling enters tested gaging hole, owing to the aperture chamfering of tested gaging hole is not just causing the taper pin center line to have different deviations with the measured hole center line, and this deviation also can be brought into measured value, and measurement result is impacted.
For this reason, the utility model proposes a kind of hole centre distance cubing that can effectively eliminate tested interporal lacuna and aperture chamfering to the influence of measuring.
The utility model content
Problem to be solved in the utility model is, how a kind of novel hole centre distance cubing is provided, this hole centre distance cubing has advantages such as simple and reasonable, easy to use, that cost of manufacture is low, accurate positioning is quick, this cubing utilizes resilient key tensioning and slide unit to finish the measurement of two hole centre distance, can avoid aperture chamfering influence, directly located by verify effective diameter place; Be applicable to that two higher hole centre distance of accuracy requirement detect, the two hole centre distance that now are mainly used in engine type component when the production of automobile enterprise is online to be detected detect.
To achieve the above object of the invention, the technical scheme that the utility model adopted is: a kind of hole centre distance cubing is provided, it is characterized in that: described hole centre distance cubing comprises: a main body, one end of described main body is provided with a circular hole that is used to install and fix resilient key, and the other end of main body is provided with a square hole that is used to install slide unit; One fixing resilient key, described fixedly resilient key are fixedly mounted in the circular hole on the main body; The bottom of described fixedly resilient key is a cambered surface band grooving structure, and the grooving fixedly bottom of resilient key is divided into several sections cambered surfaces; One slide unit, described slide unit are arranged in the square hole on the main body, are connected with main body elasticity by two axles that are contained on the linear bearing; One movable resilient key, described movable resilient key is fixedly mounted in the slide unit; The substructure of described movable resilient key is identical with the substructure of fixing resilient key; Two plane auxiliary positioning pieces all are arranged on the main body below.
According to hole provided by the utility model centre distance cubing, it is characterized in that: described hole centre distance cubing also includes one and is used for the zero calibration part in cubing school, and described calibration part is made by the intermediate value of two hole center distance tolerances.
By above-mentioned technical scheme as can be known, centre distance cubing hole, hole provided by the utility model centre distance cubing has advantages such as simple and reasonable, easy to use, that cost of manufacture is low, accurate positioning is quick, this cubing utilizes resilient key tensioning and slide unit to finish the measurement of two hole centre distance, can be used for two higher hole centre distance of accuracy requirement and detect, the two hole centre distance that now are mainly used in engine type component when the production of automobile enterprise is online to be detected detect.What is more important, this cubing can be avoided aperture chamfering influence, are directly being located by verify effective diameter place.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in the figure, this hole centre distance cubing comprises: a main body 1, an end of described main body 1 are provided with a circular hole that is used to install and fix resilient key 2, and the other end of main body 1 is provided with a square hole that is used to install slide unit 4; One fixing resilient key 2, described fixedly resilient key 2 are fixedly mounted in the circular hole on the main body 1; The bottom of described fixedly resilient key 2 is cambered surface band grooving 6 structures, and the grooving 6 fixedly bottom of resilient key 2 is divided into several sections cambered surfaces; One slide unit 4, described slide unit 4 are arranged in the square hole on the main body 1, are connected with main body 1 elasticity by two axles that are contained on the linear bearing; One movable resilient key 3, described movable resilient key 3 is fixedly mounted in the slide unit 4; The substructure of described movable resilient key 3 is identical with the substructure of fixing resilient key 2; Two plane auxiliary positioning pieces 5 all are arranged on main body 1 below; One calibration part 7, described calibration part 7 is made by the intermediate value of two hole center distance tolerances, is used for the school zero of cubing.
Fixedly resilient key 2 of the present utility model and movable resilient key 3 are the resilient keys of cambered surface band grooving 6 for the bottom, and the grooving 6 fixedly bottom of resilient key 2 and movable resilient key 3 is divided into several sections cambered surfaces, forms the elastic construction as jump ring.Position point is by the effective diameter of verify like this, thereby has avoided the aperture chamfering not over against the influence of measuring; And fixedly resilient key 2 and movable resilient key 3 bottoms are cambered surface band grooving structures, insert by behind the verify, and fixedly resilient key 2 and movable resilient key 3 just can be realized the location by auto-tensioning, thereby eliminate the influence of interporal lacuna to measurement.And the size of locating to count with tested bore dia of grooving 6 changes, and so just can effectively avoid the problem of the excessive scuffing workpiece of elasticity.
And register pin of the present utility model be the bottom is the resilient key of cambered surface band grooving, and grooving is divided into several sections cambered surfaces with the bottom of pin, forms the elastic construction as jump ring.Position point is by the effective diameter of verify like this, thereby has avoided the aperture chamfering not over against the influence of measuring; And the register pin bottom is a cambered surface band grooving structure, inserts by behind the verify, and register pin just can be realized the location by automatic tension, thereby has eliminated the influence of tested interporal lacuna to measuring.The number of locating of grooving changes with the sizes of tested bore dia, when tested bore dia hour, the corresponding minimizing of grooving number has so just reduced the elasticity of resilient key, can effectively avoid the problem of the excessive scuffing workpiece of elasticity.
