Example 1

As shown in fig. 1 to 3, the present embodiment provides a vise assembly for clamping a workpiece, including a jaw 100 and a plurality of clamping blocks 200, wherein the clamping blocks 200 are detachably connected to a side of the jaw 100 facing the workpiece.

The jaw 100 may be a fixed jaw or a movable jaw. When a workpiece is clamped, the workpiece can be clamped by opening and combining the fixed jaw 100 and the movable jaw 100. In this embodiment, the jaw 100 may be configured as a rectangular structure made of metal. Taking fig. 2 as an example, assuming that the plane shown at a in fig. 2 is the side facing the workpiece, the plurality of clamping blocks 200 are detachably connected at the side of the jaw 100 facing the workpiece, which means that the plurality of clamping blocks 200 are detachably connected at the a-side of the jaw 100, and at this time, the clamping blocks 200 should be capable of clamping the workpiece in the direction perpendicular to the a-side.

In this embodiment, the detachable connection is a connection mode that can be fixed and separated through the matching of corresponding structures, such as a threaded connection, a key connection, a snap connection, and the like. In this embodiment, the clamp block 200 and the jaw 100 are effectively fixed by a screw connection, i.e., the connection is realized by a corresponding screw fastener, which may be a screw, a bolt, or the like. For example using a bolt and nut fit.

More specifically, a plurality of clamp blocks 200 are arranged in sequence on the side of the jaw 100 facing the workpiece. The plurality of clamping blocks 200 arranged in sequence on the side of the jaw 100 facing the workpiece may or may not be on the same horizontal line. For example, several clamping blocks 200 arranged in sequence on the side of the jaw 100 facing the workpiece may be staggered in the height direction of the jaw 100. The present application does not limit the manner in which the plurality of clamping blocks 200 are arranged, nor does it limit the number of clamping blocks 200. It is understood that the number and arrangement of the clamping blocks 200 can be adjusted according to different workpieces to be clamped.

The side of the jaw 100 facing the workpiece is provided with a plurality of mounting grooves 110, the clamping block 200 is assembled in the mounting grooves 110, and the clamping block 200 relatively protrudes from the side of the jaw 100 facing the workpiece. The mounting groove 110 is provided for two main purposes, one is to accommodate the clamping block 200; secondly, the installation manner between the installation groove 110 and the clamping block 200 is adjusted to prevent the jaws 100 from tilting upwards when clamping a workpiece, which will be specifically explained in the following embodiments and will not be described herein. The clamping block 200 protrudes from the side of the jaws 100 facing the workpiece, so that the clamping force on the workpiece can be improved when the two jaws 100 are relatively close to each other.

In this embodiment, the clamping block integrally disposed with the jaw 100 in the prior art is detachably connected, and the clamping block 200 and the jaw 100 are fixed by using the screw thread fit between the bolt and the mounting hole 260, so that the whole jaw 100 does not need to be replaced when the vise needs to be replaced and maintained, and the vise is convenient to disassemble and assemble.

Example 2

Substantially the same as in example 1. The difference is that the present embodiment further defines the structure of the clamping block 200.

As shown in fig. 1, the clamp block 200 includes:

the clamping surface 210 is attached to the surface of the workpiece when the clamping block 200 clamps the workpiece;

the assembling surface 220 is attached to the bottom surface of the mounting groove 110 when the clamping block 200 is assembled in the mounting groove 110;

the clamping surface 210 of the clamping block 200 is provided with a tooth opening.

In this embodiment, the clamping block 200 is configured to be a triangular steel structure in consideration of the processing technology and the cost. The shape and material of the clamping block 200, the plating layer on the clamping block 200, etc. can be adjusted according to the different workpieces to be clamped. The tooth openings are mainly arranged for improving the friction force between the clamping block 200 and a workpiece to be clamped. Similarly, the number of the tooth gaps, the thickness and other parameters can be adjusted adaptively according to the clamped surface 210 of different workpieces.

In order to increase the friction force between the tooth openings and the surface to be clamped of the workpiece, further, the tooth openings are arranged in two rows, the tooth opening adjacent to the assembling surface 220 is a lower tooth opening 230, and the tooth opening away from the assembling surface 220 is an upper tooth opening 240, wherein:

the upper tooth opening 240 is inclined downwards relative to the surface 210 to be clamped of the workpiece;

the angle of inclination between the upper tooth 240 and the clamping surface 210 of the clamping block 200 is acute.

A vise generally comprises a base and two jaws 100, one of the jaws 100 being fixed to the base, the other jaw 100 being free to slide on the base by means of a lead screw nut transmission. In the use, the screw rod is tighter with the interior screw-thread fit of vice, rotates the screw rod with the help of the instrument, can apply external force down to the screw rod, leads to movable vice jaw 100 upwards to stick up. In order to avoid the above situation, in this embodiment, the upper tooth opening 240 is inclined downward relative to the workpiece surface 210 to be clamped, specifically, the upper half portion of the upper tooth opening 240 may be integrally formed into a downward tangent plane, where downward refers to downward inclination relative to the workpiece surface 210 to be clamped, and the inclination angle between the upper tooth opening 240 and the clamping surface 210 of the clamping block 200 is an acute angle.

Through making go up the tooth mouth 240 for the work piece treat the holding surface 210 downward sloping, just go up tooth mouth 240 with the angle of inclination between the holding surface 210 of clamp splice 200 is the acute angle, even the lead screw down exerts external force, the direction of force of keeping silent 100 is all the time down, and then can avoid keeping silent 100 the condition that upwards sticks up when the centre gripping work piece appears.

Example 3

Substantially the same as in example 2. The difference is that the clamping block 200 further comprises:

at least two wedge surfaces 250, when the clamping block 200 is assembled in the installation groove 110, the wedge surfaces 250 are attached to the side surfaces of the installation groove 110;

the wedge-shaped surface 250 is matched with the side surface of the mounting groove 110;

the wedge surface 250 is gradually inclined outward or inward in a height direction of the clip 200.

The side surface of the clamping block 200 is provided with a wedge-shaped surface 250 matched with the installation groove 110, and the wedge-shaped surface 250 is gradually inclined outwards or inwards along the height direction of the clamping block 200; meanwhile, when the upper tooth opening 240 of the clamping block 200 for clamping the workpiece clamps the workpiece, the direction of the force applied to the workpiece by the clamping block 200 is always downward, so that the jaw 100 can be further prevented from being tilted upward when clamping the workpiece.

The examples of the utility model are only right the utility model discloses a preferred embodiment describes, and not right the utility model discloses design and scope are injectd, do not deviate from the utility model discloses under the prerequisite of design idea, the field engineering technical personnel are right the utility model discloses a various deformation and improvement that technical scheme made all should fall into the protection scope of the utility model.
