Abstract

The invention relates to a vice structure improvement, and more particularly to a replaceable movable jaw downward pressurizing angle fixing type vice, mainly composed of a base, a lead screw seat, a coupling plate, an abutting member and a movable jaw. A lead screw passes through the base, and a side of the base is disposed with a stationary block. The lead screw seat has a screw hole screwed for the lead screw to be screwed and has a top surface disposed with a protrusion portion. A side of the protrusion portion facing the stationary block has a first inclined surface. The position of the coupling plate corresponding to the protrusion block of the lead screw seat has a through slot for the protrusion portion to pass through. The side edge of the through slot facing the first inclined surface of the lead screw seat has a second inclined surface. Further, the abutting member is disposed between the lead screw seat and the coupling plate so that the external periphery of the abutting member is respectively in contact with the first inclined surface and the second inclined surface to form a line contact. The movable jaw is fixedly disposed with the coupling plate, and a side of the movable jaw facing the stationary block is fixedly disposed with a jaw plate. Accordingly, while tightly clamping a workpiece, the movable jaw will automatically generate downwardly pressurizing force while facing resistance. Therefore, the workpiece not only can be exactly and tightly clamped to prevent the workpiece from generating vibration during processing but also provides good surface precision after being processed, thereby having better processing quality.

Description

Vise structure improvement

The present invention relates to a "manipulator structure improvement", and more particularly to a movable type of squatting angle solid vise which is automatically pressed down when the movable cymbal encounters resistance when the workpiece is clamped.

According to the conventional vise structure, a pedestal is disposed, the base is provided with a lead screw, the lead screw is screwed with a fixed angle fixed seat, and the base is fixed to a fixed block on one side of the movable raft.

Move to achieve the purpose of workpiece clamping.

Although the aforementioned vise can hold the workpiece for cutting work, since there is a certain gap between the lead screw and the corner seat during assembly, the movable jaw encounters resistance when the workpiece is tightly clamped. It will slightly tilt upwards, even if there is a gap, so that the level of the workpiece being clamped is not correct, which not only makes the workpiece vibrate and sway when cutting, but even the workpiece may fly out and cause danger. Moreover, the surface dimensional accuracy and level of the workpiece after processing are deteriorated, thereby affecting the overall processing quality.

However, some practitioners have further invented a kind of angle-solid vise. Although it has the effect of pressing down the movable jaw, it cannot replace the activity of different clips, and it is not convenient for the operator to repair and replace.
