FIG. 1 shows a clamp 100, which includes a base 11, a clamping assembly 12 and a fixing portion. Both the clamping assembly 12 and the fixing part are arranged on the base 11 and form a fixed connection with the base 11 . Wherein, the fixing part is used to fix the clamp 100 to the cutting machine or other related machines. In some alternative embodiments, clamp 100 is preferably used to hold a cutting machine. Here, a cutting machine is taken as an example, which generally includes a platform and a cutting part, the platform is used to place the workpiece, and the cutting part is used to directly cut the workpiece. In the process of cutting the workpiece, the cutting part needs to fix the workpiece, and the fixture 100 is generally used here. The fixing part of the fixture 100 is generally fixed to the platform by a fixing bolt. On some cutting tools with smaller application range, the clamp 100 is generally welded on the platform, which is not limited here, as long as the clamp 100 can be fixed on the platform.

The fixing part of the fixture 100 is generally arranged on the side of the base 11 to avoid affecting the relative horizontal position between the base 11 and the platform. The clamping assembly 12 is arranged on the base 11 and forms a fixed connection or a detachable connection with the base 11 . Specifically, the clamping assembly 12 includes a first clamping member 121 and a second clamping member 122, wherein the first clamping member 121 is fixedly connected to the base 11 and cannot be moved, and the second clamping member 122 is opposite to the first clamping member 122. The holding member 121 can move freely, so that it can hold workpieces of different sizes. Specifically, the first clamping member 121 is a flat plate structure, which is vertically arranged on the base 11 . In some optional embodiments, the first clamping member 121 can also move relative to the base 11, so that the clamping range of the clamp 100 can be increased, so that it can not only clamp small workpieces, but also clamp relatively small workpieces. large workpiece.

The clamping assembly 12 further includes a support base 123 for supporting the second clamping member 122 . A first through hole through which the second clamping member 122 can pass is formed on the support base 123 . The second clamping member 122 includes a clamping end 122a and an operation portion 122b, and the clamping end 122a and the operation end are connected by a connecting member 122c. The clamping end 122a can be parallel to the first clamping member 121 or form a preset angle with the first clamping member 121 when clamping the workpiece, which is not limited here. The operating portion 122b can be operated by the user, so that the second holding member 122 can be far away from the first holding member 121 or close to the first holding member 121 . Specifically, the connecting member 122c may be a connecting shaft with one end having a certain length. It passes through and causes the operating portion 122b to be disposed at an end away from the first clamp 121 . Since the support base 123 is generally a prefabricated part, the first through hole has been pre-drilled before being used to connect the second clamping part 122, and for installation needs, the first through hole is generally set larger to meet different sizes required for the connector 122c.

When the second clamping member 122 is close to the first clamping member 121 and clamps the workpiece, there is a certain clamping force therebetween, and at least part of the clamping force will act on the first through hole. However, under the action of the holding force for a long time, the first through hole will be worn to a certain extent, so that the clamping force between the first clamping member 121 and the second clamping member 122 cannot be supported, thereby causing the clamp 100 to fail. Therefore, in this embodiment, an insert 124 is also arranged in the first through hole. The insert 124 itself also has a second through hole through which the connecting piece 122c can pass. The second through hole is generally provided with an internal thread structure, while the connecting piece 122c is provided with an external thread structure, so that the first clamping piece 121 can be inserted into the first clamping piece 121. A larger clamping force is generated between the second clamping member 122 and the second clamping member 122 . In fact, insert 124 includes a first end and a second end. The first end has a protrusion 124a larger than the inner diameter of the first through hole. When the insert 124 is inserted from one end of the first through hole, the protrusion 124a can prevent the insert 124 from passing through the first through hole. The second end of the insert 124 has an internal thread structure, and the internal thread structure and the external thread structure of the connector are screwed together to achieve the fixation of the second clamping part 122 . It can be fixed on the first through hole by a nut. In order to increase the reliability of the clamp 100, an elastic member 125 is also disposed between the clamping end 122a of the second clamping member 122 and the operating portion 122b. When the second clamping member 122 is mounted on the support base 123 , one end of the elastic member 125 abuts against the clamping end 122 a and the other end abuts against the support base 123 . At this time, when the second clamping member 122 clamps the workpiece, the elastic member 125 firstly has a pre-tightening force for clamping the workpiece, so that the workpiece can be initially positioned. When the user twists the second clamping member 122 through the operating portion 122b, the second clamping member 122 gradually approaches the first clamping member 121, thereby clamping the workpiece. When the workpiece is clamped and in the process of being cut, the elastic member 125 will absorb the vibration or eccentric force from the cutting member, and can at least partially increase a certain clamping force, so that the clamping effect of the clamp 100 is better, and the clamp 100 has a longer lifespan.

Those skilled in the art should understand that the above-mentioned embodiments do not limit the present invention in any form, and all technical solutions obtained by means of equivalent replacement or equivalent transformation all fall within the protection scope of the present invention.
