Replaceable vise press down structure

Abstract

The invention discloses a replacement vice downward-pressing structure. The replacement vice downward-pressing structure is mainly composed of a base, a corner tooth seat, a linkage assembly and a moving jaw; a guide screw is arranged in the base in a penetrating mode, and a fixed block is arranged on one side of the base; a screw hole for allowing the guide screw to be arranged in a screwed modeis formed in the corner tooth seat, and a first notch is formed in the side, facing the fixed block, of the corner tooth seat and provided with a first bevel; the linkage assembly consists of a firstlocking plate and a second locking plate, a second notch is formed in one side, facing the first notch, of the first locking plate and provided with a second bevel which is obliquely in contact with the first bevel, the second locking plate is provided with a longitudinal abut sheet, and the abut sheet abuts against one side of the corner tooth seat; and the moving jaw is mounted and locked on thetop surfaces of the first and second locking plates. In this way, when a workpiece is clamped, the moving jaw encounters resistance and then can automatically produce the downward-pressing force, theworkpiece can be clamped, the vibration is prevented from generating during the workpiece processing, the surface accuracy of the processed workpiece is high, and a better processing quality is achieved.

Description

technical field [0001] The invention relates to the technical field of a vise, in particular to a replaceable vise pressing structure in which a movable jaw automatically presses down when encountering resistance when a workpiece is clamped. Background technique [0002] The conventional vise structure has a base, the base is pierced with a lead screw, the lead screw is screwed with a corner tooth seat fixed with the movable jaw, and a fixed block is fixed on the side of the base different from the movable jaw, and the movable A jaw plate can be fixed on the jaw, and a fixed jaw can be fixed on one end of the fixed block. Through the rotation of the lead screw, it can be linked with the corner tooth seat, and the corner tooth seat can synchronously drive the movable jaw to move towards the fixed jaw. , in order to achieve the purpose of the workpiece clamping operation. [0003] Although the aforementioned vise can clamp the workpiece for cutting and processing operations, ...

AI Technical Summary

Problems solved by technology

[0003] Although the aforementioned vise can clamp the workpiece for cutting and processing operations, there is a certain gap between the lead screw and the corner tooth seat during assembly, so that when the movable jaw tightly clamps the workpiece, the movable jaw encounters resistance. It will be slightly tilted upwards, and even a gap will be generated, which will make the level of the clamped workpiece not correct. It will not only cause the workpiece to vibrate and shake easily during cutting, but also cause the workpiece to fly out and cause danger. , and the dimensional accuracy and levelness of the processed workpiece surface become worse, which in turn affects the overall processing quality

[0004] And some people in the industry have further created a kind of angle fixed vise, although it has the use effect of pressing the movable jaw down, it cannot replace the movable jaw of different jaw types, and it is not convenient for the operator to dismantle and repair. Replacement, there are still inconveniences in operation and use

[0005] For the various problems of the aforementioned angle-fixed vise, the creator created Taiwan Patent No. I505914, a vise structure improvement, which can indeed solve the problem that the aforementioned conventional structure cannot be repaired or replaced; however, when the user When the lead screw is rotated, the first inclined surface of the connecting bracket can be pressed against the pressing piece, so that the pressing piece pushes down against the second inclined surface of the linkage plate, so that the linkage plate generates a downward pushing force, In this way, after using for a period of time, the first inclined surface of the protruding part will easily be broken due to the frequent use of the first inclined surface to press against the pressing member, or even the whole fracture, so that the entire vise cannot be moved; therefore, In view of the various deficiencies of the aforementioned conventional knowledge, it is necessary to further improve it
