Product processing, it is difficult to meet product requirement；
2) position gap is smaller, and product clamping is inconvenient；Operating personnel do not notice that easily dress is inclined or weighs product wounded, makes
Into product rejection；
3) it can also increase for larger aperture, the diameter of alignment pin, necessarily expend material, increase cost；
4) for the larger aluminium casting blank hole of deviation, after clamping, it may appear that the elastic phenomenon to differ, it is impossible to which workpiece is accurate
Positioning；
5) positioning product is single, it is impossible to reuses；One type fixes round pin and is only used for positioning a kind of size aperture
Product.
The content of the invention
For defect present in above-mentioned prior art, it is an object of the invention to provide a kind of internal expansion type positioner, knot
Structure is simple, and positioning is quick accurate, can solve the problem that problem produced by common fixed cylinder pin；It can realize that recycling is various simultaneously
The positioning of different pore size product；Material is saved, reduces fixture manufacturing cost.
To reach above-mentioned purpose, the technical solution adopted in the present invention is as follows：
It is a kind of quick and precisely to position internal expansion type clamping device, including swelling device shell, the first wedge type block, wedge type block bottom
Seat, the second wedge type block, piston rod and limited block, the swelling device shell open up oil inlet and oil-out, swelling device shell
Piston rod is placed in inside, and piston rod connection wedge type block base, wedge type block base equity both sides are provided with taper slideway, while are provided with and lead
To groove, it is bonded with the first wedge type block with the conical surface that the second wedge type block is carved；First wedge type block and the second wedge type block are also provided with guide groove,
And be embedded into wedge type block base guide groove, piston rod bottom is nested into limited block.
The swelling device enclosure axis direction offers a ladder hole run through, for placing piston rod.
The piston rod is multi-diameter shaft, and piston rod part is provided with screw thread, is engaged with wedge type block base threaded hole.
Set in the ladder hole of the swelling device enclosure fluted for placing body seal circle.
Set on the multi-diameter shaft of the piston rod fluted for placing piston rod seals.
Opened up on the limited block fluted for placing limited block sealing ring.
Opened up at the oil inlet of the swelling device shell fluted for placing oil inlet sealing ring.
First wedge type block and the second wedge type block are cylinder, and both sides are provided with guide groove, will according to product orientation aperture
Asking can realize and be switched fast.
Cover plate is provided with above the swelling device shell.
The present invention solves the defects of prior art being previously mentioned in background technology is present：
1st, the present invention is using may move cylindrical wedge type block Tensioning structure, during product orientation, realizes and to position hole wall complete
Fitting, in the absence of gap, requirement is accurately positioned so as to reach；
2) present invention is using the cylindrical wedge type block for being provided with guide groove, and before tension mechanism is not operating, wedge type block inside contracts, with determining
Position hole wall gap is larger, even if operating personnel do not pay attention to, can also conveniently install, cause product rejection to ask so as to solve to weigh wounded
Topic；
3) present invention is combined using class cylinder overall structure with may move cylindrical wedge type block Tensioning structure, to solve
Major diameter positioning the big problem of pore volume；
4) present invention is accurately positioned using may move cylindrical wedge type block Tensioning structure to solve blank diameter change conditions
Problem；
5) present invention is using removable cylindrical wedge type block Tensioning structure, while only wedge type block is switched, and can just solve
The product orientation of different pore size certainly, the positioning for reusing various different pore size products can be realized.
