Insert-block vise jaw

Abstract

The invention relates to a vise, in particular to an insert-block vise jaw. A fixed vise body (5) is arranged on one side of a base (9). A moving seat (6) on the lower portion of a moving vise body (4) is in sliding fit with a guide rail (8) at the top of the other side of the base. A lock screw (7) penetrates through the middle of the fixed vise body to be connected with the middle of the moving vise body. A rotary rod (10) is disposed at the end of the lock screw. Concave surfaces (16) from the upper end to the bottom are arranged in the middles of the opposing surfaces of upper jaws of the fixed vise body and the moving vise body. An insert block A (1) and an insert block B (3) are movably inserted in the concave surfaces (16) of the jaws of the fixed vise body and the moving vise body respectively. Opposing surfaces of the insert block A and the insert block B are provided with arc concaves (14) or V-shaped concaves (17) respectively. round thin-walled workpieces or square thin-walled workpieces can be clamped and fixed by the arc concaves or V-shaped concaves on the opposing surfaces of the insert block A and the inert block B.

Description

【Technical field】 [0001] The invention relates to a vise, in particular to an insert type vise jaw. 【Background technique】 [0002] Known, vise is one of essential tool of fitter, and the structure of vise mainly comprises movable vise body, fixed vise body, base, screw rod etc. to form; A screw with trapezoidal thread drives the movement in the groove of the fixed pliers, so that the jaws can be opened and closed to clamp the workpiece for operation; the lower part of the fixed pliers is provided with a base or an occlusion mechanism, which is fixed on the bench by the base or occlusion mechanism Above; For the clamping of the jaws, the jaws of the movable jaws and the jaws of the fixed jaws are mainly used. Since the strength of many workpieces is not high, it is easy to damage the workpiece if it is clamped too tightly, and it is easy to displace the workpiece if it is too loose. The current way is to pad something softer than the workpiece between the workpiece and the ...

Problems solved by technology

[0002] Known, vise is one of necessary tool of fitter, and the structure of vise mainly comprises movable vise body, fixed vise body, base, screw rod etc. to form; A screw with trapezoidal thread drives the movement in the groove of the fixed pliers, so that the jaws can be opened and closed to clamp the workpiece for operation; the lower part of the fixed pliers is equipped with a base or an occlusal mechanism, which is fixed on the bench by the base or occlusal mechanism Above; For the clamping of the jaws, the jaws of the movable jaws and the jaws of the fixed jaws are mainly used. Since the strength of many workpieces is not high, the workpiece is easily damaged if the clamp is too tight, and the workpiece is easily displaced if the clamp is too loose. The current practice is to put something softer than the workpiece between the workpiece and the jaws of the vise to protect the workpiece, such as cotton yarn, paper or soft metal; but the above method still cannot avoid the displacement or damage of the workpiece
