[0032] Example 1

[0033] like Figures 3 and 4 As shown, this embodiment provides a simple steel jaw clamp, which is suitable for being installed on a vise, and includes a fixed jaw 11 and a movable jaw 12. The fixed jaw 11 and the movable jaw 12 are arranged opposite to each other, and the fixed jaw 11 has a first mounting surface and a first clamping surface relative to each other, and the movable jaw 12 has a second mounting surface and a second clamping surface relative to each other. The first clamping surface and the second clamping surface are arranged opposite to each other, and a first steel protrusion 13 is provided on the first clamping surface, and a second steel protrusion 14 is provided on the second clamping surface. The first steel protrusion 13 and the second steel protrusion 14 are arranged alternately.

[0034] In this embodiment, the first steel protrusion 13 includes two protrusions, which are arranged transversely on both sides of the first clamping surface. The second steel protrusion 14 is arranged in the middle of the second clamping surface. The first steel protrusion 13 and the second steel protrusion 14 form a stable triangular structure.

[0035] The specific placement and dimensions of the first and second steel projections 13, 14 have been carefully calculated and designed. The height, width, and shape of the projections are adjusted to suit the workpiece to ensure optimal clamping. The triangular structure formed by the three projections evenly distributes the clamping force, ensuring a stable hold on the workpiece.

[0036] In some embodiments, the first steel protrusion 13 and the fixed jaw 11 are integrally formed, and the second steel protrusion 14 and the movable jaw 12 are integrally formed.

[0037] In other embodiments, the first steel protrusion 13 may be fixed to the fixed jaw 11 by welding. The first steel protrusion 13 may also be fixed to the fixed jaw 11 by bolting or riveting.

[0038] The second steel protrusion 14 can be fixed to the fixed jaw 12 by welding. The second steel protrusion 14 can also be fixed to the fixed jaw 12 by bolting or riveting.

[0039] Example 2

[0040] like Figures 5 and 6As shown, this embodiment provides a vise 100, including a base 20, a fixed jaw 11, a movable jaw 12, a clamping mechanism 30, and a guide rail 40. The base 20 has a mounting hole at the bottom for fixing to a machine tool workbench. A fixed block 21 is fixedly provided at one end of the base 20, and a guide rail 40 is provided at the other end of the base 20. A movable block 23 is slidably provided on the guide rail 40. The fixed jaw 11 is mounted on the fixed block 21 by screws, and the movable jaw 12 is mounted on the movable block 23 by screws 22. The vise 100 is configured to move linearly relative to the fixed jaw 11 along the guide rail 40. The clamping mechanism 30 is disposed between the base 20 and the movable block 23 and is configured to push the movable block 23 to move along the guide rail 40, thereby pushing the movable jaw 12 to clamp or release the workpiece 50. In this embodiment, the clamping mechanism 30 adopts a ball screw nut pair.

[0041] The structures of the fixed jaw 11 and the movable jaw 12 are the same as those in the first embodiment and will not be described in detail.

[0042] During use, a workpiece 50 is placed between the fixed jaw 11 and the movable jaw 12. By operating the clamping mechanism 30 of the vise 100, the first steel protrusion 13 and the second steel protrusion 14 are brought into close contact with the surface of the workpiece 50. Due to the position of the protrusions and the triangular structure, the workpiece 50 is evenly clamped and stabilized, preventing any shaking.

[0043] The three-point steel jaws of this utility model are particularly suitable for clamping workpieces with irregular shapes or uneven surfaces. For example, for casting blanks, the jaws can achieve a secure clamping without the need for additional milling process, simplifying the processing process and improving production efficiency.

[0044] In addition, in order to improve the durability of the jaws, the fixed jaw 11 and the movable jaw 12 as well as the first steel protrusion 13 and the second steel protrusion 14 are all made of high-strength alloy steel and undergo a heat treatment process to improve their hardness and wear resistance and extend their service life.

[0045] The three-point steel jaw clamp of the utility model has a simple structure, low manufacturing cost and is easy to promote and apply. Its design is not only suitable for traditional vises, but also can be applied to other clamping devices that need to clamp workpieces.

[0046] The above describes in detail the preferred embodiments of the present invention. It should be understood that numerous modifications and variations based on the concepts of the present invention can be made by those skilled in the art without inventive effort. Therefore, any technical solution that can be derived by a person skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology shall be within the scope of protection defined by the claims.
