Jaw-replaceable bench clamp

Abstract

The invention relates to a bench clamp, in particular to a jaw-replaceable bench clamp. A fixed clamp body (5) is arranged on one side of a base (9), a movable seat (6) on the lower portion of a movable clamp body (1) is slidably matched with a guide rail (8) arranged on the upper portion of the other side of the base, a locking lead screw (7) penetrates through the middle of the fixed clamp body prior to being connected with the middle of the movable clamp body, a rotating rod (10) is arranged at the end of the locking lead screw, a horizontally arranged inserting opening is arranged from one end to the other end of an upper jaw of each of the fixed clamp body and the movable clamp body, an inserting block A (2) and an inserting block B (3) are inserted into the inserting openings of the jaws of the fixed clamp body and the movable clamp body, and arc recesses (14) or 'V'-shaped recesses (17) are arranged on the opposite faces of the inserting block A and the inserting block B. Round thin-walled workpieces or square thin-walled workpieces can be clamped and fixed by the arc recesses or the 'V'-shaped recesses arranged on the opposite faces of the inserting block A and the inserting block B, and accordingly displacement and damage of the workpieces are prevented effectively.

Description

【Technical field】 [0001] The invention relates to a vise, in particular to a vise with replaceable jaws. 【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...

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
