Detailed Description
the following describes embodiments of the present invention in detail with reference to the accompanying drawings; it should be noted that the present embodiment is illustrative, not restrictive, and the scope of the invention should not be limited thereto.
The utility model provides a special device that clamps of motor casing car terminal surface and terminal surface hole, comprising a base plate 1, center positioning disk 8, jackscrew 4, kicking block 2, apron 6, toper cover 5 and push down plate subassembly 3, center positioning disk of axle center coaxial arrangement of bottom plate upper surface, toper cover of upper surface coaxial arrangement of this center positioning disk, make a plurality of spouts at the center positioning disk upper surface in the toper cover outside, all place a kicking block in every spout, this spout and kicking block set up along the circumferencial direction equipartition, and all adopt the inclined plane contact to push up tightly between the rear end of every kicking block and the toper cover, promptly: the outer side wall of the conical sleeve and the rear end of the top block are made into mutually matched inclined planes. A cover plate is coaxially arranged above the conical sleeve and the top block and is connected with the central positioning disk.
A plurality of lower pressure plate assemblies are mounted on the upper surface of the bottom plate, are located on the outer side of the central positioning plate and are uniformly distributed along the circumferential direction. The lower pressing plate component comprises a pressing plate 9, a screw 10 and an upright post 11, a long hole is formed in the pressing plate, the screw penetrates through the long hole and is connected with the bottom plate, the rear end of the pressing plate is placed on the upright post, the upright post is installed on the bottom plate, and the front end (pressing end) of the pressing plate faces the central positioning plate.
In order to avoid errors in workpiece installation, a vertical positioning column 7 is arranged on the upper surface of the bottom plate.
The utility model discloses a use method does:
The workpiece is sleeved on the central positioning disc and positioned by the positioning column, so that the workpiece is prevented from being installed wrongly. Then the jackscrew is screwed down to enable the conical sleeve to move downwards, the conical sleeve pushes the ejector blocks to move outwards simultaneously by utilizing the inclined plane, the front ends of the ejector blocks all move to the outer side of the central positioning disc and tightly push the inner wall of the workpiece, and centering is achieved. And finally, positioning and locking the side edge of the lower part of the workpiece by using the lower pressing plate component.
