The content of the invention
The present invention provides a kind of hand power screw hinge type clamp system, and this kind of structure not only avoid operation handle and, while thrust is big, can only effectively control the quality of product in the limitation of seal face side.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of hand power screw hinge clamping mechanism, including positioning support, it is characterised in that：The side of positioning support extends upward support arm, and locating piece is connected with support arm；Connecting plate is horizontally fixed with positioning support, the stage casing of a pressure arm is hinged on connecting plate, the upper end of pressure arm is hinged with briquetting, and the lower end of pressure arm is hinged with connector, and the position of the briquetting is corresponding with the position of locating piece；The lower end of positioning support is provided with mounting hole, mounting hole is fixed with thread bush, horizontally disposed adjusting bolt is rotatably connected in thread bush, the two ends of adjusting bolt pass from the both sides of positioning support, end in adjusting bolt positioned at support arm side is provided with rotary handle, the end positioned at pressure arm side and connector floating connection in adjusting bolt.
Further restriction to above-mentioned technical proposal, adjusting bolt is with the floating connecting structure of connector：Connector is provided with detent, and the head of adjusting bolt is located in detent, and head and the detent gap of adjusting bolt coordinate to be realized floating, and the axial limiting of screw rod and connector is realized by being fixed on the cover plate of detent oral area.Advantage：1. the cooperation of detent and cover plate, improves the stability and service life of whole mechanism.2. simple structure, low manufacture cost, be easy to handling.
To the further restriction of above-mentioned technical proposal, the connecting plate is with the articulated structure of pressure arm：Including bearing pin, be equipped with the surface at the two ends of bearing pin with clamp coordinate draw-in groove, clamp by screw be fixed on at draw-in groove cooperation.Advantage：1. clamp plays stop to bearing pin, so as to improve the stability and service life of whole mechanism.2. simple structure, low manufacture cost, be easy to handling.
To the further improvement of above-mentioned technical proposal, the rotary handle connection end of the adjusting bolt is provided with back tightening nut.Advantage：In order to the further locking of screw rod, so as to improve the stability of whole mechanism.
Beneficial effect：1. change operation direction, make operation enhanced convenience：The technical characteristic for driving pressure arm by screw rod is realized；Compare traditional mechanism, the operating position of this structure can be particularly suitable for that part space is small on the opposite of seal face, and need the part that inner side clamps.2. this gear grips power is big, can effectively control part deformation, and can be suitably used for all kinds of weld jigs.
