Abstract
A device for quickly disassembling a chain belongs to the technical field of mechanical maintaining tools and is used for quickly disassembling the chain without damage. The technical scheme is that the device is composed of a clamp, a press plate, a compression bolt and a fastening screw. A clamping groove is arranged on one side of the clamp, the width of the clamping groove is matched with that of the chain which is placed in the clamping groove, the press plate is placed above the chain, a through hole is arranged at the center of the press plate, a screw hole is arranged on the bottom face of the clamping groove of the clamp, the through hole of the press plate vertically faces the screw hole of the clamping groove, the compression holt is matched with the screw hole of the clamping groove, a horizontal screw hole is arranged on the lateral face of the clamp, the position of the horizontal screw hole corresponds to the position of a chain pin roll, and threads of the fastening screw are matched with the horizontal screw hole. When the device is used for disassembling the chain, the press plate and the clamp tightly clamp the chain, and the fastening screw is screwed in from the screw hole on the lateral face of the clamp to jack up the chain pin roll and finish disassembly of the chain. The device greatly reduces chain disassembly time, improves working efficiency and reduces labor intensity of workers.
Description
Technical field
The utility model relates to a kind of device of dismantling chain, belongs to the mechanical maintenance tool in use technical field.
Background technology
In flight-line maintenance work, the mechanical chain dismounting generally is with general tools such as hammer, pliers the chain pin to be broken to reach the dismounting purpose, and this traditional method required time is long and may cause chain to damage or distortion.
The utility model content
Technical problem to be solved in the utility model provides a kind of device of quick-detachment chain, and this device can the quick-detachment chain, and can not damage and cause the chain distortion.
The technical scheme that solves the problems of the technologies described above is:
A kind of device of quick-detachment chain, it is comprised of jig, pressing plate, hold-down bolt, jackscrew, one side of jig has draw-in groove, the width of draw-in groove and the width of chain are complementary, chain is placed in the draw-in groove, pressing plate is placed on the top of chain, there is through hole at the center of pressing plate, on the draw-in groove bottom surface of jig screw is arranged, the through hole of pressing plate and the screw of draw-in groove are vertically opposite, and the screw of hold-down bolt and draw-in groove is complementary, and in the side of jig horizontal screw are arranged, the position of horizontal screw is corresponding with the chain hinge pin position, and the jackscrew screw thread matches with horizontal screw.
The device of above-mentioned quick-detachment chain, upper surface shape and the chain bottom surface of described draw-in groove bottom surface are complementary, and the underside shape of pressing plate and the upper surface of chain are complementary.
The beneficial effects of the utility model are:
When adopting the utility model dismounting chain, pressing plate and jig clamp chain, and jackscrew ejects chain hinge pin from the screw precession of jig side, finish the chain dismounting.The utility model can reduce the chain take-down time greatly, increases work efficiency, and alleviates worker's labour intensity.
Description of drawings
Fig. 1 is structural representation of the present utility model;
