Abstract
The utility model relates to a detection pin assembly used for detecting product surface hole position, which comprises a detection pin pedestal, a detection pin, a compact block and two bulb plungers. A surface matched with the product surface and a through hole corresponded to a product surface standard orifice are provided on the detection pin pedestal. The detection pin is composed of a guiding segment, a detection segment and a handle segment which are connected integrally, and a ring groove is provided on the guiding segment. The compact block is sleeved on the detection segment of the detection pin, and two bulb plungers are symmetrically arranged on the inner wall of the through hole of the detection pin pedestal. The detection pin assembly can be used for detecting the hole position at any site on the product surface, and the operation is convenient and fast.
Description
Technical field
The utility model relates to a kind of cubing, relates in particular to a kind of test pin assembly for detection of product face position.
Background technology
Often can run into take the product face as benchmark the problem that has a hole to detect on this face simultaneously in the cubing design.Disposal route commonly used in prior art has following two kinds:
One, the motion detection pin adds the clamp compression
Fit with simulated block and product face during design, make the test pin pilot hole in the simulated block relevant position, at product disposed outside clamp seat and clamp: the test pin size is by position, hole diameter, tolerance and position degree calculating gained.
Then the simulated block of first product being fitted during use makes jaws close product and simulated block fully fit, then gets the motion detection pin and insert corresponding test pin pilot hole.
This structure operation step needed for three steps.Limitation is arranged when structure is used, during away from product edge, need to lengthen the clamp pressure handle when the position, hole.The long own wt that causes of pressure handle is very large, and one-piece construction is inharmonious, affects clamp serviceable life.Run into this situation and usually understand operation technique two.
Two, threaded motion detection pin
During design, with the applying of simulated block and product face, in simulated block relevant position central punch, the test pin size is divided into multistage: first paragraph is thread segment, and size is not more than detection segment; Second segment is guide section, and size is got the integer between thread segment and detection segment; The 3rd section is detection segment, and size is calculated gained by position, hole diameter, tolerance and position degree; The 4th section is the band knurling handle.Need leave the position between the 3rd section and the 4th section compact heap is installed.
Then the simulated block of first product being fitted during use is got the motion detection pin and is inserted corresponding threaded hole, then screws in test pin and make the compact heap on test pin can compress product.
This structure operation step also needed for three steps.Can't use the problem of clamp when having solved the position, hole away from product edge on structure, but need rotate the multi-turn test pin during operation just can make compact heap compress product, and compact heap rotates with respect to the product face when compressing product process, may be to the product surface injury.Do not have clamp convenient in the practical operation sense.
The utility model content
The purpose of this utility model is exactly the problem that exists in order to solve above-mentioned prior art, and a kind of test pin assembly for detection of product face position is provided.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of test pin assembly for detection of product face position, and it comprises:
The test pin pedestal which is provided with the adaptive surface of product face with corresponding to the through hole of product face gauge orifice position;
Test pin is made of the guide section that is connected, detection segment and handle section, and the diameter of guide section is less than the diameter of detection segment, and the diameter of detection segment is provided with annular groove less than the diameter of handle section on guide section;
Compact heap is sleeved on the detection segment of test pin, and its thickness is a bit larger tham the length after detection segment deducts product thickness;
Two bulb plungers, symmetry is arranged on the through-hole wall of test pin pedestal.
When testing product inserted test pin the test pin pedestal and puts in place, described ball head column fork clip entered in the annular groove of test pin to realize compressing the location.
Owing to having adopted above technical scheme, applicable to the position, hole of any position on the testing product face, operation is convenient, quick for detection of the test pin assembly of product face position for the utility model.
Description of drawings
Fig. 1 is the utility model for detection of the perspective view of the test pin assembly of product face position;
Fig. 2 is the utility model for detection of the decomposition texture schematic diagram of the test pin assembly of product face position;
Fig. 3 is the utility model for detection of the front elevation of the test pin assembly of product face position.
Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, the test pin assembly for detection of product face position of the present utility model comprises test pin pedestal 1, test pin 2, compact heap 3 and two bulb plungers 4.
Compact heap 3 is sleeved on the detection segment of test pin, and its thickness is a bit larger tham the length after detection segment deducts product thickness, in order to can compress product.
Two (also can with four) bulb plunger 4 symmetries are arranged in the tapped through hole of test pin pedestal.
the principle of work of the test pin assembly for detection of product face position of the present utility model is, during detection, the operator first is affixed to product the test pin pedestal, again test pin is passed the position, hole of product and insert the test pin pedestal, test pin moves downward the steel ball that utilizes Leading end chamfer to back down the ball head column plug head, increased force will makes test pin continue to move downward, when the lateral grooves of test pin begins to contact with steel ball, steel ball begins to eject and enters in the test pin lateral grooves, steel ball carries out in groove fully subsequently, binding force to the test pin axially-movable is provided simultaneously, the compact heap (the relative test pin of compact heap this moment is fixing dead) that is sleeved on this moment on the detection segment of test pin is fully fitted product and adaptive profile.Only have when withdrawal force is enough large (50N left and right) just test pin can be extracted, the axial force that this power produces test pin during much larger than product deformation.
