For solve above-mentioned technical problem, this utility model by the following technical solutions:
A kind of self-centering fixture for taper hole product, including pedestal, a mandrel it is connected with on described pedestal, on described mandrel, slip cap is provided with in the taper hole for insert processed product the tapered sleeve forming radially location, described pedestal is provided with the axial locating surface for contacting with processed product, described self-centering fixture also includes for being pressed abd fixed on processed product on axial locating surface to stop processed product dismantled and assembled latch assembly of movement on the axial direction of mandrel, it is provided with between described pedestal and tapered sleeve and makes tapered sleeve hold out against assembly with the elasticity of taper hole close contacting fit.
Above-mentioned self-centering fixture, it is preferred that described elasticity holds out against assembly and includes that compression spring, described compression spring are sheathed on mandrel, and one end of compression spring offsets with pedestal, and the other end offsets with tapered sleeve.
Above-mentioned self-centering fixture, it is preferred that endoporus one end of described tapered sleeve is provided with stepped hole, forms a containing cavity between described stepped hole and mandrel, described compression spring part stretches in described containing cavity.
Above-mentioned self-centering fixture, it is preferred that described dismantled and assembled latch assembly includes that locking nut, described mandrel are provided with external screw thread, and described locking nut is connected with the external screw thread on mandrel.
Above-mentioned self-centering fixture, it is preferred that described pedestal is provided with the projecting ring section arranged around mandrel, and described axial locating surface is located on described projecting ring section.
Compared with prior art, the utility model has the advantage of: this utility model is used for the self-centering fixture of taper hole product in use, the taper hole of processed product is sheathed on tapered sleeve, use dismantled and assembled latch assembly to be pressed abd fixed on axial locating surface by processed product and can form axially location, during processed product is secured in a press, elasticity holds out against assembly makes tapered sleeve hold out against the taper hole of processed product, form axially location towards processed products, realize self-centering, need not be corrected towards processed products, be greatly improved working (machining) efficiency;Dismantling dismantled and assembled latch assembly after machining can be taken out by product, handling the most lightly facilitate.This self-centering fixture uses dismantled and assembled latch assembly and axial locating surface can form reliable and stable axial location, tapered sleeve is held out against the resilient force of assembly by elasticity and holds out against the taper hole of processed product and form radially location simultaneously, on the premise of ensure that reliable and high-precision radial direction location, need not strike tightly, from without crowded wound or scratch taper hole, therefore in the course of processing, no matter processed product is not had extruding taper hole yet and produces the situation of axial displacement by great axial force, and location and machining accuracy have been effectively ensured.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1, this utility model is for the self-centering fixture of taper hole product, including pedestal 1, a mandrel 2 it is connected with on pedestal 1, on mandrel 2, slip cap is provided with in the taper hole 101 for insert processed product 100 tapered sleeve 3 forming radially location, the conical surface 31 tapering of tapered sleeve 3 is consistent with the tapering of taper hole 101, pedestal 1 is provided with the axial locating surface 11 for contacting with processed product 100, self-centering fixture also includes for being pressed abd fixed on processed product 100 on axial locating surface 11 to stop processed product 100 dismantled and assembled latch assembly of movement on the axial direction of mandrel 2, it is provided with between pedestal 1 and tapered sleeve 3 and makes tapered sleeve 3 hold out against assembly with the elasticity of taper hole 101 close contacting fit.In use, the taper hole 101 of processed product 100 is sheathed on tapered sleeve 3, use dismantled and assembled latch assembly to be pressed abd fixed on axial locating surface 11 by processed product 100 and can form axially location, during processed product 100 is secured in a press, elasticity holds out against assembly makes tapered sleeve 3 hold out against the taper hole 101 of processed product 100,100 forms axially location towards processed products, it is achieved self-centering, need not 100 be corrected towards processed products, be greatly improved working (machining) efficiency;Dismantling dismantled and assembled latch assembly after machining can be taken out by product, handling the most lightly facilitate.This self-centering fixture uses dismantled and assembled latch assembly and axial locating surface 11 can form reliable and stable axial location, tapered sleeve 3 is held out against the resilient force of assembly by elasticity and holds out against the taper hole 101 of processed product 100 and form radially location simultaneously, on the premise of ensure that reliable and high-precision radial direction location, need not strike tightly, from without crowded wound or scratch taper hole 101, therefore in the course of processing, no matter processed product 100 is not had extruding taper hole 101 yet and produces the situation of axial displacement by great axial force, and location and machining accuracy have been effectively ensured.
