[0023] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0024] Example 1

[0025] See also Figure 1 to Figure 2 This embodiment provides a clamp for a round tube workpiece. The clamp for a round tube workpiece 10 comprises two symmetrical jaw profiles 1, the front face 8 of the jaw profile is provided with a V-shaped notch for clamping the round tube workpiece 10; the back face 9 of the jaw profile is provided with a plurality of small holes 5 for embedding magnets 6.

[0026] In the present embodiment, the V-shaped notch includes a transverse V-shaped notch and a plurality of vertical V-shaped notches, which are used to clamp round tube workpieces 10 of different diameters. The opening angles of the plurality of vertical V-shaped notches are different. There are two vertical V-shaped notches, including a first vertical V-shaped notch 3 and a second vertical V-shaped notch 4; the opening angle of the first vertical V-shaped notch 3 is 110˚, and the opening angle of the second vertical V-shaped notch 4 is 130˚. Specifically, three different V-shaped notches are provided on the front side 8 of the jaw profile, and different V-shaped notches can be flexibly selected according to the different characteristics of the round tube workpiece 10. The transverse V-shaped notch 2 can clamp a horizontally placed round tube workpiece 10, such as Figure 5 As shown, the diameter of the round tube workpiece 10 can be 0.4-1 inches (9-25 mm); the first vertical V-shaped notch 3 and the second vertical V-shaped notch 4 can vertically clamp the round tube workpiece 10, and two vertical V-shaped notches with different opening angles are selected according to the round tube workpiece 10 with different diameter ranges. For example, the opening angle of the first vertical V-shaped notch 3 is 110°, as shown in FIG. Figure 3 As shown, the diameter range of the corresponding round tube workpiece 10 can be 0.4-1 inch (9-25 mm); the opening angle of the second vertical V-shaped notch 4 is 130°, as shown in FIG. Figure 4 As shown, the corresponding diameter range of the round tube workpiece 10 can be 1-2 inches (25-50 mm). In this embodiment, a V-shaped notch is provided on the front face 8 of the jaw profile, so that the round tube workpiece 10 is not easy to slip on the clamp, thereby reducing the potential safety hazard during operation and not easily damaging the surface of the round tube workpiece 10.

[0027] In this embodiment, the number of small holes 5 is 3, which are arranged at intervals along the back side 9 of the jaw profile; the magnet 6 is glued to the small hole 5 by AB glue, and is used to be adsorbed on the bench vise. Specifically, a drilling tool is used to drill small holes evenly at intervals on the back side 9 of the jaw profile. The depth of the small holes can be determined according to the thickness of the jaw profile 1. For example, if the thickness of the jaw profile 1 is 23mm, the depth of the small holes can be 2.7mm; the interval position can be determined according to the length of the jaw profile 1. For example, if the length of the jaw profile 1 is 150mm, the interval position can be 50mm. According to the number of small holes, a corresponding number of magnets are selected, and the magnets 6 are embedded in the small holes 5 and glued firmly with AB glue. The firmly glued magnet 6 makes it convenient for the operator to adsorb this clamp for the round tube workpiece 10 on the original jaw iron of the bench vise by magnetic force, which solves the problem that the existing technology is fixed and installed by screws, which makes it troublesome to replace the jaws, and improves work efficiency.

[0028] In this embodiment, the back side 9 of the jaw profile is further provided with a baffle 7, which is provided along the edge of the back side 9 of the jaw profile. Specifically, the edge of one side of the back side 9 of the jaw profile is provided with a baffle 7 having a length equal to that of the jaw profile 1, and the combination of the baffle 7 and the jaw profile 1 is in an "L" shape, which is beneficial to increase the adsorption area when the clamp for the round tube workpiece 10 is adsorbed on the original jaw iron of the bench vise by magnetic force, and the clamp can be better adsorbed on the original jaw iron of the bench vise.

[0029] In this embodiment, the jaw profile 1 is made of aluminum alloy. Specifically, the jaw profile 1 is made of aluminum alloy, which is one of the light metal materials with good casting performance and plastic processing performance, so that V-shaped notches are symmetrically opened on the front faces 8 of the two symmetrical jaw profiles in this embodiment.

[0030] In this embodiment, a clamp for a round tube workpiece is provided. The clamp for the round tube workpiece 10 is convenient for clamping the round tube workpiece 10 by opening a V-shaped notch on the front of the jaw profile, and is not likely to cause the round tube workpiece 10 to slip; and by setting V-shaped notches at different angles and in different directions, it is possible to clamp round tube workpieces 10 of different diameters. By opening a small hole on the back of the jaw profile and embedding a magnet, the clamp is directly adsorbed on the jaw iron of the bench vise, which is convenient for replacing the jaws and improves work efficiency.

[0031] The working principle of the utility model is: according to the diameter and shape of the round tube workpiece 10 to be clamped, the horizontal V-shaped notch 2 or the first vertical V-shaped notch 3 or the second vertical V-shaped notch 4 on the front face 8 of the jaw profile is selected and clamped. Then the clamp with the round tube workpiece 10 is adsorbed on the original jaw iron of the bench vise through the magnet 6 on the back face 9 of the jaw profile.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
