[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0034] The utility model provides a vise clamp, such as Figures 1 to 3As shown, it includes a chassis 10, a mounting seat 20, a connecting seat 30, a front clamping block 40, a rear clamping block 50 and a driving unit 60, the mounting seat 20 is rotatably connected to the chassis 10; the connecting seat 30 is hinged to the mounting seat 20; the front clamping block 40 is fixed to the connecting seat 30; the rear clamping block 50 is opposite to the front clamping block 40 and can be slidably connected to the connecting seat 30 in a direction close to or away from the front clamping block 40, and the rear clamping block 50 can clamp the workpiece with the front clamping block 40 by sliding in the direction of the front clamping block 40; the driving unit 60 is connected to the rear clamping block 50, and is used to drive the rear clamping block 50 to slide.

[0035] Specifically, by setting the chassis 10, the mounting seat 20, the connecting seat 30, the front clamping block 40, the rear clamping block 50 and the driving unit 60, the vise clamp can be fixed to the workbench through the chassis 10, the mounting seat 20 is connected to the chassis 10, the connecting seat 30 is hinged to the mounting seat 20, the front clamping block 40 is fixed to the connecting seat 30, and the rear clamping block 50 is opposite to the front clamping block 40 and slidably connected to the connecting seat 30. When the workpiece is clamped, the workpiece is placed between the front clamping block 40 and the rear clamping block 50, and the driving unit 60 drives the rear clamping block 50 to slide in the direction of the front clamping block 40. Cooperating with the front clamping block 40, the workpiece is clamped. Since the mounting seat 20 is rotatably connected to the chassis 10, and the connecting seat 30 is hinged to the mounting seat 20, the workpiece can be driven to rotate in the horizontal direction by rotating the mounting seat 20 to adjust the angle of the workpiece in the horizontal direction. By rotating the connecting seat 30, the workpiece can be driven to rotate in the vertical direction to adjust the angle of the workpiece in the vertical direction. Therefore, by rotating the mounting seat 20 and the connecting seat 30, the clamping angle of the workpiece can be adjusted, thereby being able to adapt to the processing of the workpiece in different directions, providing convenience for the processing of the workpiece.

[0036] It can be understood that the driving unit 60 can be any driving structure such as a motor and a screw module, a hydraulic cylinder, etc. that can drive the rear clamping block 50.

[0037] In one embodiment, Figures 1 to 3 As shown, the driving unit 60 includes a driving screw 61, one end of which is rotatably connected to the rear clamping block 50, and the other end of which extends toward the sliding direction of the rear clamping block 50 and is threadedly connected to the connecting seat 30. Specifically, during the rotation of the driving screw 61, the driving screw 61 moves axially through the portion threadedly connected to the connecting seat 30, thereby driving the rear clamping block 50 to slide, thereby achieving the clamping or loosening of the workpiece.

[0038] In one embodiment, to achieve the locking of the connection seat 30, as shown in FIG. Figures 1-2As shown, the vise clamp further includes a locking unit 70, which is connected to the mounting seat 20 and the connecting seat 30 to limit the rotation of the connecting seat 30. Specifically, the locking unit 70 is connected to the mounting seat 20 and the connecting seat 30 at both ends, so as to limit the rotation of the connecting seat 30 around the mounting seat 20, thereby keeping the workpiece stable and facilitating the processing of the workpiece.

[0039] In one embodiment, Figures 1-2 As shown, the locking unit 70 includes a locking member 71 and a first locking bolt 72. The locking member 71 is hinged to the mounting seat 20 and extends toward the connecting seat 30. The first locking bolt 72 passes through the mounting seat 20 and is threadedly connected to the connecting seat 30 to limit the rotation of the locking member 71. Specifically, after the rotation adjustment of the connecting seat 30 is completed, the locking member 71 only needs to be locked to the connecting seat 30 through the first locking bolt 72, so that the locking member 71 can be fixed, and then the connecting seat 30 can be locked through the locking member 71.

[0040] It is understandable that a plurality of locking holes at intervals may be provided on the locking member 71 or the connecting seat 30 , and when the connecting seat 30 is rotated to a certain angle, the first locking bolt 72 may be connected to the corresponding locking hole.

[0041] In one embodiment, Figures 1-2 As shown, the hinged portion of the connecting seat 30 and the mounting seat 20 is located at one end of the connecting seat 30 close to the front clamping block 40, and the locking member 71 is provided with a through slot 711, which is located at one end of the locking member 71 close to the connecting seat 30 and extends in a direction away from the front clamping block 40. The first locking bolt 72 is provided with the through slot 711, and the connecting seat 30 can drive the first locking bolt 72 to slide along the through slot 711 by rotating. Specifically, through the provision of the through slot 711, when the connecting seat 30 needs to be rotated, it is only necessary to loosen the first locking bolt 72 first, and then the connecting seat 30 can be rotated. During the rotation of the connecting seat 30, the locking member 71 will be driven to rotate, and the first locking bolt 72 will slide along the through slot 711. When it rotates to a suitable angle, the first locking bolt 72 can be tightened.

[0042] In one embodiment, in order to achieve the stability of the locking member 71, as shown in FIG. Figures 1-2 As shown, the locking unit 70 further includes a second locking bolt 73, and the locking member 71 is hinged to the mounting seat 20 through the second locking bolt 73. The second locking bolt 73 can limit the rotation of the locking member 71 by moving toward the mounting seat 20. Specifically, when the connecting seat 30 is rotated to a suitable angle, the first locking bolt 72 and the second locking bolt 73 can be locked at the same time, thereby achieving the locking of the locking member 71 to prevent the locking member 71 from loosening.

[0043] In one embodiment, in order to achieve the locking of the rear clamping block 50 after sliding, as shown in FIG. Figure 3As shown, the vise clamp further includes a limit unit 80, which is connected to the connecting seat 30 and the rear clamping block 50, and is used to limit the sliding of the rear clamping block 50. Specifically, after the rear clamping block 50 cooperates with the front clamping block 40 to clamp the workpiece, the rear clamping block 50 can be locked by the limit unit 80 to prevent the rear clamping block 50 from moving during the workpiece processing, thereby ensuring the processing quality of the workpiece.

[0044] In one embodiment, Figure 3 As shown, the limiting unit 80 includes a locking plate 81 and a third locking bolt 82. The locking plate 81 is located at one side of the rear clamping block 50 and can be fitted with the connecting seat 30 by moving toward the rear clamping block 50. The third locking bolt 82 passes through the locking plate 81 and is threadedly connected to the rear clamping block 50. The third locking bolt 82 can press the locking plate 81 against the connecting seat 30 by moving toward the rear clamping block 50. Specifically, after the workpiece is clamped, the locking plate 81 only needs to be pressed against the connecting seat 30 by tightening the third locking bolt 82, and the movement of the locking plate 81 relative to the connecting seat 30 can be limited by the friction between the locking plate 81 and the connecting seat 30, thereby realizing the locking of the rear clamping block 50. When the rear clamping block 50 needs to be controlled to slide, the third locking bolt 82 only needs to be loosened.

[0045] In this embodiment, the third locking bolt 82 and the locking plate 81 are located at the lower side of the rear clamping block 50 . When the third locking bolt 82 needs to be operated, the connecting seat 30 needs to be rotated upward to expose the third locking bolt 82 .

[0046] In one embodiment, Figure 1 As shown, in order to achieve the locking of the mounting seat 20 after rotation, the chassis 10 is provided with a fourth locking bolt 11, the fourth locking bolt 11 is threadedly connected to the chassis 10, the mounting seat 20 is sleeved on the fourth locking bolt 11 and is rotatably connected with the fourth locking bolt 11, and the fourth locking bolt 11 can press the mounting seat 20 against the chassis 10 by moving toward the chassis 10. Specifically, the mounting seat 20 can achieve stable rotation of the mounting seat 20 relative to the chassis 10 by being sleeved on the fourth locking bolt 11. After the mounting seat 20 is rotated to a suitable angle, the rotation of the mounting seat 20 can be limited by only locking the fourth locking bolt 11.

[0047] In one of the embodiments, a protruding structure is provided in the middle portion of the chassis 10, and a groove structure that is only compatible with the protruding structure of the chassis 10 is provided on the ground of the mounting seat 20. The mounting seat 20 is sleeved on the protruding structure of the chassis 10 through the groove structure to stabilize the rotation of the mounting seat 20 relative to the chassis 10.

[0048] In one embodiment, Figure 1As shown, the mounting seat 20 is provided with a limit hole 21, and the limit hole 21 is used for the locking rod of the workbench to pass through, so that the locking rod limits the rotation of the mounting seat 20. Specifically, after the mounting seat 20 is rotated to a suitable angle, the locking rod fixed to the workbench can be passed through the limit hole 21, so that the rotation of the mounting seat 20 can be limited, and the fourth locking bolt 11 can be used together to achieve the stability of the mounting seat 20.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
