Description

Double jaw vice folder jaw hold-down devices

Technical field

The utility model relates to a kind of vice, refers to a kind of Double jaw vice folder jaw hold-down devices especially.

Background technology

Commonly use Double jaw vice quite general, be mainly used in clamping two pieces workpiece simultaneously, and its maximum characteristic sets up two kinds of different screw threads at single screw rod or assembled screw rod exactly, if its side is right-handed thread, opposite side is then left hand thread, so just can drive two to press from both sides jaws synchronous toward interior or synchronously move, and then make two outward and press from both sides jaws and can clamp working substance or synchronously loosen working substance simultaneously when turn screw rod simultaneously.

But, screw rod is established two kinds of screw threads and then controls two folder jaws tight and unclamp the pattern of working substance, although the simple and easy understanding of structure, but there is the problem that industry generally finds is, when pressing from both sides jaw clamping of workpieces, workpiece often produces the situation that workpiece up tilts because of the impact of clamping area power, cause the vertical plane error of processing work and affect assembling precision, therefore product is in way present stage, need the processing of each details to need very precisely to reach required precision as far as possible, but also therefore cause delaying of the increase of cost and production capacity.

Therefore, for the problem points existing for above-mentioned conventional construction, how to develop a kind of innovation structure having more desirable practicality, real consumer eagerly looks forward to, and is also target and direction that relevant dealer must make great efforts research and development breakthrough.

In view of this, the utility model designer this in manufacturing development and design experiences that to be engaged in Related product for many years, for above-mentioned target, in detail after design and scrupulous assessment, obtain the utility model of a true tool practicality eventually.
