The technical scheme of the utility model including model, locating pin and location bolt, the model is the arc plate, is equipped with a basic hole and a plurality of inspection hole on the model, inspection hole and basic hole await measuring according to the standard, and the position structure in hole distributes on the part, the diameter of basic hole is less than the inspection hole diameter, and the diameter in hole equals on inspection hole diameter and the part that awaits measuring, the locating pin is the second grade step shaft with the location bolt, and in the path end of locating pin inserted the model basic hole, location bolt path end inserted in the model inspection hole.
Description
Technical field
The utility model relates to a kind of mechanical detection means, is specifically related to a kind of pick-up unit for arc-shaped hole part.
Background technology
Brake strips etc. have connection hole type parts for cambered surface, are widely used in, in automobile chassis braking device, having very critical positions in automobile brake, are related to the security in vehicle traveling.It is thread connection between brake strip and brake-shoe, between brake strip and brake-shoe, the Anawgy accuracy of cambered surface affects the size of damping force, the dimensional accuracy of brake strip cambered surface upper screwed hole determines the precision that brake strip coordinates with brake-shoe, because of its particular/special requirement, vernier caliper is leaned on for a long time to the size detection of its cambered surface upper fixing hole always.This type of part because of detected face be cambered surface, detection reference is not easily determined, the precision detecting size is difficult to ensure, cause product piece in assembling process because of cambered surface and and cambered surface on the quality of error effect assembling of position, hole and production efficiency.
Utility model content
The utility model provides a kind of pick-up unit, for detecting the size in hole on arc-shaped hole part, improving accuracy of detection, ensureing the assembly quality of product.
The technical solution of the utility model is: comprise model, register pin and fastening screw, described model is arc plate, model is provided with a datum hole and multiple detect aperture, described detect aperture and datum hole distribute according to the positional structure in hole on standard part to be measured, the diameter of described datum hole is less than detect aperture diameter, the equal diameters in hole on detect aperture diameter and part to be measured, described register pin and fastening screw are secondary multidiameter, the miner diameter end of register pin inserts in model datum hole, and fastening screw miner diameter end inserts in model detect aperture.
As preferably, described register pin miner diameter end and datum hole clearance fit, its axial length is less than model thickness 1-2mm, and bigger diameter end axial length is equal with part thickness to be measured, its top cylindrical to be tapering be conical surface of 5 °, bottom outside diameter is less than the internal diameter 0.1-0.2mm of hole in piece part to be measured.
As preferably, described fastening screw miner diameter end diameter is less than detect aperture diameter 0.1-0.5mm, and axial length is greater than part thickness 8-10mm to be measured, and bigger diameter end diameter is greater than miner diameter end diameter 5-8mm, and axial length is 30-35mm.
The beneficial effects of the utility model are: the utility model is applicable to detect the part that cambered surface has multiple connecting hole and pilot hole, quick detection can be realized, this structure of the detecting device is simple, easy to use, accurate positioning, is applicable to manual operations, detect compared to vernier caliper, this device more easily determines detection reference, and therefore accuracy of detection is high, and product quality and production efficiency significantly improve.

Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
The present embodiment comprises model 2, register pin 1 and fastening screw 3, model 2 is arc plate, model 2 is provided with a datum hole 6 and multiple detect aperture 5, detect aperture 5 and datum hole 6 distribute according to the positional structure in hole on standard part to be measured, the diameter of datum hole 6 is less than the diameter of detect aperture 5, the equal diameters in hole on detect aperture diameter and part to be measured 4, register pin 1 and fastening screw 3 are secondary multidiameter, the miner diameter end 13 of register pin 1 inserts in model datum hole 6, and the miner diameter end 32 of fastening screw 3 inserts in model detect aperture 5.
In the present embodiment, miner diameter end 13 and datum hole 6 clearance fit of register pin 1, its axial length is less than model 2 thickness 1-2mm, bigger diameter end 12 axial length is equal with part 4 thickness to be measured, its top cylindrical to be tapering be conical surface 11 of 5 °, play the guiding role when mounted, bottom outside diameter is less than the internal diameter 0.1-0.2mm of hole in piece part to be measured.
Fastening screw 3 miner diameter end 32 diameter is less than the diameter 0.1-0.5mm detecting hole in piece part, and axial length is greater than part 4 thickness 8-10mm to be measured, and bigger diameter end 31 diameter is greater than miner diameter end diameter 5-8mm, and axial length is 30-35mm.
When detecting, by this pick-up unit horizontal positioned on the table, the miner diameter end of register pin is inserted in the datum hole of model, until the cambered surface of register pin bigger diameter end lower surface and model is adjacent to; Corresponding for the inside arc face of a detected part hole and detent fit are loaded, and the outside cambered surface of part intrados to be detected and model is fitted, the laminating degree clearance gauge of cambered surface detects, error is less than 0.05mm, on part to be measured, the miner diameter end of all the other each hole fastening screws inserts and detects its position dimension, and the miner diameter end of fastening screw can be inserted in model detect aperture as qualified.
