Abstract

The utility model provides a bench vice, includes two jaws of fixed jaw, movable jaw, respectively installs one set in fixed jaw, movable jaw and accomodates backplate device, accomodate backplate device including fixed connection at the stationary blade of two jaw lower part lateral walls, articulated have the articulated frame through the damping axle on the stationary blade, the backplate passes through the axle rotation to be connected at the articulated frame tip, the epaxial torsional spring that wears to be equipped with, the one end butt of torsional spring is on the articulated frame, the other end butt is on the backplate, the backplate be wooden board or polymer board. The bench clamp can attach two guard plates to two jaws by rotating the hinged frame and the guard plates, and cannot generate clamping marks on a workpiece due to lower hardness of the guard plates when clamping the workpiece.

Description

Bench clamp

Technical Field

The utility model relates to a pair of bench clamps, in particular to a pair of bench clamps capable of preventing a workpiece from generating clamping marks, and belongs to the technical field of tools.

Background

The bench clamp is a common tool for clamping a workpiece, and the applicant finds that the conventional bench clamp has the following problems in the process of machining parts by using the bench clamp for a long time: because the bench clamp has high hardness, the parts often have dent when being processed by the bench clamp, secondary damage to the parts is caused, and the appearance and the precision of the parts are damaged; in order to meet the requirements of precision and attractive appearance, the workpiece is required to be processed after being processed, the surface of the workpiece is processed, the surface of the workpiece can be damaged in the process of eliminating the clamping mark, and the applicant searches thousands of patents related to bench clamps in Chinese patent application, and does not find a technical scheme capable of preventing the workpiece from generating the clamping mark in clamping.

Disclosure of Invention

The utility model aims to solve the problem that the prior bench clamp generates clamping marks when clamping a workpiece, and provides the bench clamp.

In order to achieve the purpose of the utility model, the following technical scheme is adopted: the utility model provides a bench vice, includes two jaws of fixed jaw, movable jaw, respectively installs one set in fixed jaw, movable jaw and accomodates backplate device, accomodate backplate device including fixed connection at the stationary blade of two jaw lower part lateral walls, articulated have the articulated frame through the damping axle on the stationary blade, the backplate passes through the axle rotation to be connected at the articulated frame tip, the epaxial torsional spring that wears to be equipped with, the one end butt of torsional spring is on the articulated frame, the other end butt is on the backplate, the backplate be wooden board or polymer board.

Further; the guard board is L-shaped, and after the guard board is unfolded, an L-shaped transverse plate is positioned on the upper end face of the jaw.

Further; the fixing pieces are two, the end parts of the articulated frame, which are connected with the fixing pieces, are U-shaped, holes are formed in the fixing pieces, the marble is installed at the hole parts, screw holes are formed in the two edges of the U-shaped of the articulated frame, a jacking spring is installed in the screw holes, the jacking bolt is screwed in the screw holes, one end of the jacking spring is abutted to the marble, and the other end of the jacking spring is abutted to the jacking bolt.

The utility model has the positive and beneficial technical effects that: the bench clamp can attach two guard plates to two jaws by rotating the hinged frame and the guard plates, and cannot generate clamping marks on the workpiece due to lower hardness of the guard plates when the workpiece is clamped, and can be stored in the bench clamp when the workpiece is not in the clamping marks. The torsion spring is used in the structure, torsion exists in the stretching and recovering process, the self-return function can be realized, and the friction force always exists in the recovering state due to the fact that the structure is designed by the structure to be used with the ejection spring and the marble, so that shaking caused by vibration or gravity is avoided, and the stability is good.

Fig. 2 is an enlarged schematic view of a portion of fig. 1.

Fig. 3 is a schematic view of the spring at the point of tightening.

Description of the embodiments

In order to more fully explain the practice of the utility model, examples of the practice of the utility model are provided. These examples are merely illustrative of the present utility model and do not limit the scope of the utility model.

The utility model will be explained in further detail with reference to the accompanying drawings, in which: 1, a movable jaw; 2: a fixed jaw; 3: a guard board; 4: a hinge bracket; 5: a fixing piece; 6: a bolt; 7: a shaft; 8: a torsion spring; 9: a marble; 10: the spring is tightly propped.

In fig. 1, the storage guard plate device on the movable jaw is in an unfolded state, and the other set of storage plate device is a storage device.

As shown in the drawing, the bench vice comprises a fixed jaw 2 and a movable jaw 1, wherein a set of storage guard plate devices are respectively arranged in the fixed jaw and the movable jaw, each storage guard plate device comprises a fixing plate 5 fixedly connected to the side walls of the lower parts of the two jaws, two hinge brackets are hinged to the fixing plates through damping shafts, in the implementation, the two fixing plates 5 are arranged at the ends, connected with the fixing plates, of each hinge bracket 4 are U-shaped, holes 11 are formed in the fixing plates, marble 9 is arranged at the hole parts, screw holes are formed in the two edges of the U-shaped of the hinge brackets, a jacking spring 10 is arranged in each screw hole, one end of each jacking spring is abutted to the corresponding marble, and the other end of each jacking spring is abutted to each jacking bolt. The spring, the spring and the bolt form a damping shaft. The backplate 3 pass through axle 7 rotation and connect at the articulated frame tip, the backplate be wood board or polymer board, in this embodiment, the backplate adopts the nylon board, wears to be equipped with torsional spring 8 on the axle 7, the one end butt of torsional spring 8 is on articulated frame 4, the other end butt is on backplate 3, the backplate be L shape, the backplate expandes the back, the diaphragm of L shape is located on the up end of keeping silent.

The bench clamp is used, the upward-turning hinge frame and the guard plate can be unfolded, and the downward-turning hinge frame and the guard plate can be stored. The storage guard board device is positioned in the bench clamp after storage, and the use of the bench clamp is not affected.
