Summary of the invention
The utility model provides a kind of hand power screw hinge type clamp system, and this kind of structure not only avoid operating grip can only in the limitation of seal face side, and thrust is large simultaneously, effectively can control the quality of product.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of hand power screw hinge clamping mechanism, comprises positioning support, it is characterized in that: the side of positioning support extends upward support arm, and support arm is connected with locating piece; On positioning support, level is fixed with connecting plate, and the stage casing of a pressure arm is hinged on connecting plate, and the upper end thereof of pressure arm has briquetting, and the lower end of pressure arm is hinged with connector, and the position of described briquetting is corresponding with the position of locating piece; The lower end of positioning support is provided with installing hole, installing hole is fixed with thread bush, horizontally disposed adjustment bolt rotary is connected in thread bush, the two ends of adjustment screw rod pass from the both sides of positioning support, end adjustment screw rod being positioned at support arm side is provided with rotary handle, adjustment screw rod is positioned at end and the connector floating connection of pressure arm side.
To the further restriction of technique scheme, the floating connecting structure of adjustment screw rod and connector is: connector is provided with detent, the head of adjustment screw rod is arranged in detent, the head of adjustment screw rod and detent matched in clearance realize floating, and are realized the axial limiting of screw rod and connector by the cover plate being fixed on detent oral area.Advantage: the 1. cooperation of detent and cover plate, improves stability and the service life of whole mechanism.2. structure is simple, cost of manufacture is low, be convenient to handling.
Further limit technique scheme, the articulated structure of described connecting plate and pressure arm is: comprise bearing pin, the surface at the two ends of bearing pin is equipped with the draw-in groove coordinated with clamp, and clamp is fixed on and draw-in groove cooperation place by screw.Advantage: 1. clamp plays stop to bearing pin, thus the stability and the service life that improve whole mechanism.2. structure is simple, cost of manufacture is low, be convenient to handling.
Further improve technique scheme, the rotary handle link of described adjustment screw rod is provided with back tightening nut.Advantage: in order to further lock screw rod, thus improve the stability of whole mechanism.
Beneficial effect: 1. change direction of operating, make operation more convenient: drive the technical characteristic of pressure arm to realize by screw rod; Relatively traditional mechanism, the operating position of this structure on the opposite of seal face, can be particularly suitable for part space little, and needs the part of inner side clamping.2. this gear grips power is large, effectively can control part deformation, and can be applicable in all kinds of weld jig.
