Description
Technical field
This utility model relates to a kind of alignment pin, a kind of expansion pin that can be accurately positioned product.
Background technology
Cubing is to be widely used in the fixture of the on-line checking such as stamping parts and weldment inspection, is used for controlling the various chi of product
The simple and direct instrument of very little (such as aperture, bulk etc.), improves production efficiency and controls quality, it is adaptable to the product of production in enormous quantities
Product.And workpiece is correct, rational location is the accurate basis measured, current cubing positions workpiece all with straight pin and diamond pattern
Between the location mode of pin positions, and the product orientation that in stamping parts hole flanging dimensional accuracy is low and sleeve pipe welding deformation is caused exists
Gap, so that workpiece can not be accurately positioned.
Expansion pin utilizes the principle that wedge coordinates with slide block, instead of in cubing with straight pin and the location side of diamond pattern pin
Formula, by being automatically adjusted the radial dimension of expansion pin, testing accuracy and the product postorder that can be effectively improved product add
The machining accuracy of work.
Summary of the invention
The technical problems to be solved in the utility model, is to provide the essence in a kind of hole for detecting stamping parts or weldment
Really positioner, can be effectively improved testing accuracy and the machining accuracy of product postorder processing of product.
This utility model is achieved in that the expansion pin of a kind of positioning action, including secondary pin, hand lever, stub, at least two
Slide block and return unit；Described secondary pin upper end is equipped with described hand lever, and lower end is tapering point；Described secondary pin rotary setting is in described master
In pin；At least two radial slider grooves it are provided with in described stub；Described slide block is located at the interior also energy of described slide block slot correspondingly
Radially slide along slide block slot；And the inner face between described at least two slide blocks forms one for inserting that the tapering point of described secondary pin plugs
Groove；Being equipped with a groove radially on the outer face of described slide block, described return unit is sheathed in described groove.
Further, described slide block the inner is an inclined-plane.
The utility model has the advantage of: automatically adjusted by the radial dimension to expansion pin that coordinates of pair pin and slide block
Whole, efficiently solve between existing due in stamping parts hole flanging dimensional accuracy is low and sleeve pipe welding deformation is caused product orientation
Gap, and the problem that can not be accurately positioned.Slide block can be fixed in slide block slot by return unit and reset slide block.New by this practicality
The location expansion pin of type can be effectively improved testing accuracy and the machining accuracy of product postorder processing of product.

Detailed description of the invention
Referring to shown in Fig. 1 and Fig. 2, this utility model is that to arrange four slide blocks be preferred embodiment.
The expansion pin 100 of a kind of positioning action, including secondary pin 1, hand lever 2, stub 3, at least two slide block 4 and return unit 5；Institute
Stating secondary pin 1 upper end and be equipped with described hand lever 2, lower end is tapering point 11；Described secondary pin 1 rotary setting is in described stub 3；Described
At least two (embodiment shown in figure is four) radial slider groove 31 it is provided with uniformly in stub 3；Described slide block 4 one a pair
Should to be located at described slide block slot 31 interior and can radially slide along slide block slot 31 on ground；Described slide block 4 the inner is an inclined-plane 41, described four
Inner face between slide block 4 forms a slot 6 plugged for the tapering point 11 of described secondary pin 1；It is all provided with on the outer face of described slide block 4
Having a groove 42 radially, described return unit 5 is sheathed in described groove 42, and described return unit 5 is for fixing described slide block 4
In described slide block slot 31, described slide block 4 can be resetted again.
Operation principle:
Expansion pin 100 is inserted in the pilot hole of cubing, then by rotating the hand lever 2 on described secondary pin 1, make described pair
Pin 1 moves downward, when the described secondary tapering point 11 of pin 1 contacts with the inclined-plane 41 of described slide block 4 and continues to move downward
Meanwhile, described slide block 4 starts to move out respectively along the slide block slot 31 of described stub 3, until described slide block 4 touches workpiece 7
Flange or the inner side of sleeve pipe, the continuation described hand lever 2 of rotation is till tightening, and expansion pin 100 reaches greatest diametrical dimension, now
Workpiece 7 is inflated pin 100 and fixes, and workpiece 7 is difficult to be moved or rotated, and eliminates free gap, serves fixing for workpiece 7 fixed
The effect of position.After detection completes, opposite direction rotates described hand lever 2, makes described secondary pin 1 move upward, and slide block 4 is described multiple
Inward under the effect of position part 5, quickly can take off workpiece 7 from expansion pin 100.
When positioning workpiece 7, expansion pin 100 is swollen when being tightened to the limit, and at least two described slide blocks 4 connect with workpiece
Touch.That is: the quantity that the slide block 4 of expansion pin contacts with workpiece 7 is relevant with the welding deformation amount of the precision of workpiece or sleeve pipe, its hole flanging
Precision is the highest or sleeve pipe welding deformation amount is the least, then slide block 4 quantity contacted with workpiece 7 is the most.
Although the foregoing describing detailed description of the invention of the present utility model, but those familiar with the art should
Working as understanding, our described specific embodiment is merely exemplary rather than for the limit to scope of the present utility model
Fixed, those of ordinary skill in the art, in the equivalent modification made according to spirit of the present utility model and change, should
Contain in scope of the claimed protection of the present utility model.
