Description

There is the afterburning bench vice that moves both sides

Technical field

The utility model relates to machine tools, particularly relates to a kind of bench vice.

Background technology

Bench vice has the bench vice frame, in the prior art, and the fixed fastener that bench vice frame one side has one; Movable fastener is arranged in the chute of opposite side, between movable fastener and fixed fastener, have afterburning screw rod, rotate afterburning screw rod and just can make movable fastener walking; Reach the purpose of stepping up object, in the prior art, such bench vice has afterburning with a side only; Have awkward shortcoming during the object that is processed with, its operating efficiency is not high yet in addition.

Summary of the invention

The purpose of the utility model is exactly to above-mentioned shortcoming, provides a kind of and can both sides rotates, there is the afterburning bench vice that moves both sides easy to use, that efficient is higher.

The technical scheme of the utility model is achieved in that there is the afterburning bench vice that moves both sides, and comprises the bench vice frame, and it is characterized in that: described bench vice frame has the chute that runs through both sides; The two ends of chute are equipped with two movable fasteners; Promptly first fastener and second fastener have two afterburning swing arms and connect, be i.e. first swing arm and second swing arm between two fasteners; First swing arm rotates in second fastener, stretch out first fastener has free end; Second fastener and first swing arm are threaded through swing arm, and second swing arm rotates in first fastener, stretch out second fastener has free end, and first fastener and second swing arm are threaded through swing arm; At first swing arm, the second swing arm free end has spanner.

The beneficial effect of the utility model is: the bench vice of this spline structure have can both sides rotate, easy to use, advantage that efficient is higher.

Description of drawings

Fig. 1 has the structural representation of the afterburning bench vice that moves for the utility model both sides.

Wherein: 1, bench vice frame 2, first fastener 3, second fastener 4, first swing arm

5, second swing arm 6, spanner

Specific embodiments:

Below in conjunction with accompanying drawing the utility model is further described.

Of Fig. 1, there is the afterburning bench vice that moves both sides, and comprise bench vice frame 1; It is characterized in that: described bench vice frame 1 has the chute that runs through both sides, and the two ends of chute are equipped with two movable fasteners, i.e. first fastener 2 and second fastener 3; Have two afterburning swing arms between two fasteners and connect, promptly first swing arm 4 and second swing arm, 5, the first swing arms 4 rotate in second fastener 3, stretch out first fastener free end is arranged; Second fastener 3 and first swing arm 4 are threaded through swing arm, and second swing arm 5 rotates in first fastener 2, stretch out second fastener 3 has free end, and first fastener 2 and second swing arm 5 are threaded through swing arm; At first swing arm, 1, the second swing arm, 2 free ends spanner 6 is arranged.

Better technical effect is: first swing arm 4 connects through pressure bearing in second fastener 3, and second swing arm 5 connects through pressure bearing in first fastener 2.
