Abstract

A dual clamp vise jaw downward-pressing device comprises a vise with first and second driving bases transversely passing through first and second cylinders. The second cylinder is provided with a threaded hole for engagement with a threaded section of a driving rod. The first driving base has a front stepped hole assembled with a front protrusion ring of the driving rod and a rear through hole receiving a spring and a limiting member assembled therewith. The spring abuts a perpendicular surface of the first cylinder. A lateral first cylinder hole extends to a front end of the front stepped hole that is longitudinally arranged. The first cylinder is obliquely cut at a location close to the protrusion ring and a lower position to form a plane with a highest edge of the plane higher than a center of the first cylinder, such that when a workpiece is tightly clamped by a force and the slanted plane is under force to resist the highest edge, the slanted plane can only rotate toward the vertical direction to approach and abut a front end of a second protrusion front edge, and the first cylinder forms rotational downward pressure transmitted to the first jaw clamping surface to form a downward force for downwardly pressing the workpiece.

Description

Double clamp vise clamp pressing device

The invention provides a technical field of a vise, in particular to a technology of providing a double-clamping jaw-clamping device, wherein the plane of the first cylinder is chamfered, and the thrust is reversed and converted into the first folder. The pressure can prevent the work from being upturned and difficult to process or pinch.

According to the conventional double-clamp vise, it is mainly used to clamp two workpieces at the same time, and its biggest feature is to make two different threads in a single screw or a combined screw, such as a right-hand thread on one side. The other side is a left-handed thread, so that when the screw is rotated, the two clamps can be simultaneously moved inward or synchronously outward, so that the two clamps can simultaneously clamp the work or simultaneously relax the work.

However, the screw has two kinds of threads to control the mode of clamping and releasing the two clamps. Although the structure is simple and easy to understand, there is a common problem in the industry that when the clamp clamps the workpiece, the workpiece tends to be The influence of the clamping surface force causes the workpiece to be lifted upwards, which causes the vertical surface error of the workpiece to be processed and affects the assembly accuracy.
