Abstract

The utility model relates to a machining tool, in particular to a downward-pressing tightening type vice. The downward-pressing tightening type vice comprises a vice frame, wherein two ends of the vice frame are provided with two movable clamping pieces with beveled structures; the beveled positions of the movable clamping pieces are hinged on the vice frame; and pressing ports are arranged below the inner sides of the upper parts of the movable clamping pieces. The downward-pressing tightening type vice also comprises a rotary rod with threads; the vice frame is provided with a hole for installing the rotary rod; a structure for meshing with the threads of the rotary rod is arranged below the movable clamping pieces; one movable clamping piece is meshed with the rotary rod by the threads, and the other movable clamping piece is meshed with the rotary rod by threads of a gear shifting device; a wrench is arranged at the outer part of the rotary rod; and a V-shaped opening is arranged on the vice frame. The downward-pressing tightening type vice has the advantage of firmer and more labor-saving clamping.

Description

Press down and add the compact form bench vice

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, parallel moving between fixed fastener and the movable fastener; Add to hold among parallel slit, to add exactly and hold, have to add and hold shortcoming not firm, that workpiece comes off easily.

Summary of the invention

The purpose of the utility model is exactly to above-mentioned shortcoming, and a kind of more firm bench vice of holding that adds is provided---and press down and add the compact form bench vice.

The technical scheme of the utility model is achieved in that to press down and adds the compact form bench vice, comprises the bench vice frame, it is characterized in that: described bench vice frame two ends are equipped with the movable fastener of two sector structures; The knuckle place of movable fastener is hinged on the bench vice frame; Below the movable fastener upper inner mouth of pressure is arranged, it also comprises a threaded swing arm, and the bench vice frame has the hole that swing arm is installed; The structure that identical swing arm screw thread is arranged below the movable fastener; One of them movable fastener coincide through screw thread and swing arm, and another movable fastener coincide through gear shift device screw thread and swing arm, and there is spanner described swing arm outside.

Further say: have the V-arrangement opening above the described bench vice frame.

The beneficial effect of the utility model is: the bench vice of this spline structure have add hold more firmly, labour-saving advantage more.

Description of drawings

Fig. 1 adds the structural representation of compact form bench vice for the utility model presses down.

Wherein: 1, bench vice frame 2, movable fastener 3, knuckle place 4, pressure mouth

5, swing arm 6, V-arrangement opening.

Specific embodiments:

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

Of Fig. 1, press down and add the compact form bench vice, comprise bench vice frame 1; It is characterized in that: described bench vice frame 1 two ends are equipped with the movable fastener 2 of two sector structures, and the knuckle place 3 of movable fastener 2 is hinged on the bench vice frame 1, have below movable fastener 2 upper inner to press mouthfuls 4; It also comprises a threaded swing arm 5; Bench vice frame 1 has the hole that swing arm is installed, and the structure of identical swing arm screw thread is arranged below the movable fastener 2, and one of them movable fastener 2 is identical through screw thread and swing arm; Another movable fastener 2 coincide through gear shift device screw thread and swing arm, and there is spanner described swing arm outside.

Further say: have V-arrangement opening 6 above the described bench vice frame 1.

When installation gear conversion equipment can guarantee to rotate swing arm, two movable fasteners 2 pressed down or rising simultaneously simultaneously, and the gear shift device is known technology for those skilled in the art, is not giving unnecessary details.
