Description

Chuck of working bench

The utility model belongs to the clamping device of a kind of workbench in metal working or the carpenter's processing.

The instrument of being used always when workbench is carpenter or metal processing operation, it is in order to bearing and clamp working substance, is beneficial to constructions such as boring, cutting, and more advanced workbench more can be controlled the inclination that its table top is made suitable angle, so that make working substance be set in fixed angle, be beneficial to do special construction.The steady job object space formula of common workbench, be on work top, to be provided with the anchor clamps that are positioned at relative position, working substance is placed the centre of two anchor clamps, controlling two anchor clamps again pulls to the folder of working substance and reaches the effect that tightens up, but because be located at the anchor clamps of workbench is the setting that is plane formula, so when clamping, only have horizontal force.Like this, if impose on axial force when operation, then working substance just may break away from anchor clamps, and therefore, normally used workbench anchor clamps are the chucking powers that can't provide enough.

The purpose of this utility model is to provide a kind of workbench clamping device of mainly being made up of platform, a body of rod and grip slipper, and it not only has more powerful chucking power, and has the more folder direction of pulling, thereby has solved the existing in prior technology problem.

The technical scheme that the utility model adopted is that it mainly is made up of the platform body of rod and grip slipper.Wherein, be provided with a trepanning and body of rod cross-under at an end of grip slipper, the other end is pivoted with a U-shaped seat.In this U-shaped seat, be articulated with an eccentric cam that extends spanner, when the outer bottom of U-shaped seat is contacted with the working substance of putting on workbench, pulls this spanner and can make the cam top compel U-shaped seat inner bottom surface and working substance is clamped.

In the utility model, also the lower end of the body of rod can be provided with the taper sheath, and extend a screw rod in the lower end of taper sheath, this screw rod is enclosed within together with the taper sheath gives on the hole that is located at workbench, cooperate this screw rod locking with nut or knob with screw again, so as to adjusting the level angle position of the body of rod.

The utility model can also change the U-shaped seat end of grip slipper and is made as a screw, spiral shell is provided with the driving screw that a lower end is combined with top supporting part in this screw, be provided with a swingle in the upper end of driving screw, when rotating this swingle, can control the packing of support surface working substance.

Therefore characteristics of the present utility model are novel structure, uniqueness, easy to operate, and having the workbench of making has multidirectional folder to pull to working substance, and folder pulls very firmly, the utlity model has very strong practicality.
