Description

Jaw plate of flat-nose pliers

technical field

The utility model relates to an improvement of parts of a flat-nose pliers, in particular to a jaw plate of a flat-nose pliers capable of clamping narrow and thin-walled workpieces. the

Background technique

Flat-nose pliers are a general-purpose fixture, which is suitable for the installation of small and medium-sized and regular-shaped workpieces. It is used to clamp the workpiece for cutting by fixing it on the machine tool table. Usually, the size of the workpiece clamped by flat-nose pliers generally does not exceed the width of the jaws, otherwise the processed part will interfere with the jaws; moreover, the processed surface of the workpiece must be higher than the jaws, and the lower surface needs to be narrower and thicker than the workpiece. Appropriate and high-precision contour pads are used to prevent the workpiece from loosening during processing and affect the processing accuracy. The flat-nose pliers as shown in accompanying drawing 1, comprise fixed jaw 1, movable jaw 2, fixed jaw body 5, the first fixed jaw plate 3a and the first movable jaw plate 4a; Described movable jaw 2 and fixed The clamp body 5 is connected by a lead screw 6, and the movable jaw 2 can be pushed by the screw rod 6 to move along the fixed clamp body 5; the fixed jaw 1 and the fixed clamp body 5 are tightly connected, and the first fixed jaw plate 3a and The first movable jaw plate 4a is respectively fixed on the fixed jaw 1 and the movable jaw 2 by hexagon socket bolts; the first fixed jaw plate 3a and the first movable jaw plate 4a are flat plates respectively; this structure First, for the processing of narrow and long workpieces, because its size exceeds the clamping range of the fixed jaw plate and the movable jaw plate, the workpiece is prone to tilting and difficult to clamp under the action of cutting force, which cannot meet the requirements. Processing requirements; second, for the processing of thin-walled parts, due to the lack of rigidity, the contour block needs to be supported under the workpiece to avoid deformation of the workpiece due to the clamping force, and the processing accuracy of the contour block is high, so The workpiece preparation time is long, and waste products are prone to occur, and the processing efficiency is extremely low. the

Utility model content

The purpose of the utility model is to provide a jaw plate of a flat-nose pliers capable of clamping narrow and thin-walled workpieces in order to overcome the deficiencies of the prior art.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a jaw plate of a flat-nose pliers, including a body, and at least two mutually perpendicular steps are arranged on the inner side of the end of the body.
