Claw-type rotatable dynamic balance base cap clamping vice

Abstract

The invention discloses claw-type rotatable dynamic balance base cap clamping vice, comprising a vice main body, a fulcrum shaft, a dynamic balance base cap, a fixed base cap and two or more than two clamping jaws, wherein, the fulcrum shaft is fixed on a nut base at the middle of the vice main body. The dynamic balance base cap is sheathed on the fulcrum shaft, so as to lead the dynamic balance base cap to adjust the angle according to the rotation of the fulcrum shaft; the dynamic balance base cap is selected, two or more than two locating holes are arranged at the upper end of the fixed base cap and are arbitrarily combined with various clamp claws and supporting pieces, so as to form the claw-type rotatable balance base cap clamping vice; the clamping claws and the supporting pieces are utilized to clamp workpieces with rough surfaces, round and irregular shapes, so as to achieve the functions of precise and balanced clamping workpieces.

Description

technical field [0001] The invention relates to a claw-type vise clamped by a rotatable balance jaw, especially a vise with two or more jaws on a rotatable dynamic balance jaw and a fixed jaw for balanced clamping. . Background technique [0002] Known vises such as Figure 16 As shown, it is composed of vise body 10, screw rod 20, movable jaw 30, fixed jaw 40 and other components. The movable jaw 30 can move forward or backward by turning the screw 20 by the user. The clamping blocks 301 and 401 on the rear end surface of 40 clamp the workpiece 50 . If this vise is applied to the workpiece 50 of clamping thin shape, it is necessary to place a support block 60 at the bottom of the workpiece 50, so that the workpiece 50 is elevated at the height near the top of the movable jaw 30 and the fixed jaw 40, and then the clamping block 301, The thin workpiece 50 is clamped by the edge of 401, but the known movable mouthpiece 30 and fixed mouthpiece 40 have a certain height H, if t...

If this vise is applied to the workpiece 50 of clamping thin shape, it is necessary to place a support block 60 at the bottom of the workpiece 50, so that the workpiece 50 is elevated at the height near the top of the movable jaw 30 and the fixed jaw 40, and then the clamping block 301, The thin workpiece 50 is clamped by the edge of 401, but the known movable mouthpiece 30 and fixed mouthpiece 40 have a certain height H, if the clamping position is higher (the longer the force arm), the moment M generated by the reaction force N will be more Large, and there is a certain gap between the movable mouthpiece 30 and the screw rod 20, which will cause the movable mouthpiece 30 and the fixed mouthpiece 40 to rise up (tilt) in the opposite direction, affecting the stability of its clamping and the precision of post-processing.

Secondly, there are all kinds of parts in the industry today, which need to be clamped by a vise to carry out processing operations. The jaws of the known vise are of a fixed shape, which cannot meet the needs of various workpiece clamping, such as thin Workpieces, round workpieces, triangular, polygonal or other irregular-shaped workpieces, and castings with rough surfaces, height gaps, workpieces with rough surfaces cut by a sawing machine, skewed workpieces, etc., are difficult to clamp smoothly with a vise
