One end of clamp arm is slidably connected in guide groove.
Further, the drive disk is provided with several leading arms, and guide groove, the guiding are provided on the leading arm
Slot gradually extends to the outside of drive disk.
Further, one end that the clamp arm is connect with guide groove is connected with idler wheel, and the roller-coaster, which is connected to, leads
Into slot.
Further, retention bead is provided on the clamp arm.
Further, the clamping side of the clamp arm free end is removably connected with gripping block.
Further, at least three locating pins are removably connected on the positioning surface.
It further, further include support plate, the support plate is connect by support column with disk is clamped, the support plate and folder
Be provided with clamping cylinder between tight disk, bottom end and the support plate of the clamping cylinder are fixed, the telescopic rod of the clamping cylinder and
Drive disk is fixed.
The beneficial effects of the utility model are as described below: a kind of disk part by performing self-centering fixture passes through clamping cylinder
Mobile that clamp arm completion is driven to move radially, workpiece is clamped by clamp arm, and is guaranteed by the pressure maintaining effect of clamping cylinder
The reliability of clamping；When the device is used for a long time, the free end of clamp arm is easy to appear " horn mouth " phenomenon, at this moment replacement folder
The long-time service of clamp arm can be realized in tight block.
Detailed description of the invention

Specific embodiment
The utility model is further described with reference to the accompanying drawing.
A kind of disk part by performing self-centering fixture as described in attached drawing 1 to 5, including disk 1 is clamped, the clamping disk 1 is circle
Cylindricality, it is described clamp disk 1 one side be positioning surface 2, the another side opposite with the positioning surface 2 be provided with guide post 3 and
Three guide sleeves 4, several guide sleeves 4 are circumferentially spaced, and the guide sleeve 4 is radially extended along disk 1 is clamped, described to lead
To column 3 and the coaxial arrangement of disk 1 is clamped, slidably connects clamp arm 5, the freedom of the clamp arm 5 in each guide sleeve 4
It holds to 2 side of positioning surface and turns down to form pinching end, drive disk 6 is slidably connected in the guide post 3, is set on the drive disk 6
Several guide grooves 7 are equipped with, several guide grooves 7 are corresponded with several clamp arms 5, and one end of the clamp arm 5 is sliding
It is dynamic to be connected in guide groove 7.
The drive disk 6 is provided with several leading arms 8, is provided with guide groove 7 on the leading arm 8, the guide groove 7 by
Gradually extend to the outside of drive disk 6；One end that the clamp arm 5 is connect with guide groove 7 is connected with idler wheel 15, and the idler wheel 15 is sliding
Dynamic to be connected in guide groove 7, idler wheel 15 can reduce the frictional force between clamp arm and guide groove, and the clamping disk is provided with recessed
Slot 17 forms resigning effect in leading arm moving process.Drive disk is close to disk is clamped, and each clamp arm is along the radial direction for clamping disk
It is drawn close to center, completes Workpiece clamping；Drive disk is far from disk is clamped, and each clamp arm is along clamping disk radially away from center, pine
Go into operation part.
It is provided with retention bead 9 on the clamp arm 5, to limit the minimum diameter that can clamp workpiece.
