DETAILED DESCRIPTION

[0019] The following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the scope of protection of the present invention.

[0020] See attached Figure 1-5As shown, a vise with double-row tooth jaws in this embodiment includes a base box 1, a limiting ring 2, a pair of sliders 4, a screw rod 6, a pair of clamping blocks 9, a pair of clamping blocks 11 and bolts 16. Slide grooves 3 are arranged on the inner walls on both sides of the base box 1, and a pair of sliders 4 slide in the slide grooves 3. The limiting ring 2 is fixedly connected to the middle part of the base box 1, and the middle part of the screw rod 6 rotates in the limiting ring 2. The front half and the rear half of the screw rod 6 are respectively screwed to the pair of sliders 4; a first mounting hole 15 is arranged on the clamping block 9, and the bolt 16 passes through the first mounting hole 15 and is screwed to the slider 4; the clamping block 11 is connected to the top of the clamping block 9, and the pair of clamping blocks 11 clamp the workpiece 8; the side surfaces of the clamping block 11 are provided with more than two rows of teeth from top to bottom.

[0021] By arranging more than two rows of teeth from top to bottom on the side of the clamp block 11 to form a clamping surface, the clamping line is more firmly clamped than the clamping line formed by only a single row of teeth in the prior art. The clamping firmness of the workpiece 8 is improved.

[0022] Specifically, a first row of teeth 12 and a second row of teeth 13 are provided on the side surface of the clamp block 11 from top to bottom.

[0023] In order to increase the elasticity between the clamp block 11 and the clamp block 9 , the utility model is further configured as follows: an arc groove 14 is provided between the clamp block 11 and the clamp block 9 .

[0024] In order to limit the position of the workpiece 8 between the pair of clamp blocks 11, the utility model is further configured as follows: a second mounting hole 17 is provided on the side of the clamp block 9, a pin 18 is connected to the second mounting hole 17, a connecting plate 19 is rotatably connected to the pin 18, a screw 20 is screwed to one end of the connecting plate 19, the screw 20 passes through the connecting plate 19, and the end of the screw 20 abuts against the side of the workpiece 8. By tightening or unscrewing the screw 20, the position of the workpiece 8 between the screw 20 and the pair of clamp blocks 11 can be adjusted, which is conducive to the pair of clamp blocks 11 clamping the workpiece 8.

[0025] In order to facilitate the rotation of the screw rod 20, the utility model is further configured as follows: the outer end of the screw rod 20 is connected to a hand wheel 21.

[0026] In order to facilitate the rotation of the screw rod 6 , the utility model is further configured as follows: a servo motor 7 is connected to the bottom box 1 , and the servo motor 7 drives the screw rod 6 to rotate.

[0027] In order to reduce the friction between the clamping block 9 and the bottom box 1 , the utility model is further configured as follows: a lubricating oil groove 10 is provided on the surface of the bottom box 1 facing the clamping block 9 .

[0028] In summary, the method of using the vise with double-row tooth jaws shown in the utility model is: start the servo motor 7, the servo motor 7 drives the screw rod 6 to rotate, the middle part of the screw rod 6 rotates in the limit ring 2, and the front half and the rear half of the screw rod 6 respectively drive a pair of sliders 4 to move relative to each other. Since the clamping block 9 is fixedly connected to the slider 4 by the bolt 16, and the clamp block 11 is fixedly connected to the clamping block 9, when the pair of sliders 4 approach each other, the pair of clamping blocks 9 approach each other, and the pair of jaws approach each other, and the workpiece 8 is clamped between the pair of jaws. Since more than two rows of teeth are provided, the workpiece 8 is clamped more firmly. Since the lubricating oil groove 10 is provided on the bottom box 1, the friction between the bottom box 1 and the clamping block 9 is reduced. Since the arc groove 14 is provided between the clamping block 11 and the clamping block 9, it is more conducive to clamping the heterogeneous workpiece 8. By rotating the connecting plate 19 around the pin shaft, the end of the screw rod 20 is extended into between the pair of clamp blocks 11 and toward the side of the workpiece 8; then, the hand wheel 21 is rotated, and the end of the screw rod 20 moves toward the workpiece 8 until it abuts against the side of the workpiece 8, limiting the position of the workpiece 8 so that the pair of clamp blocks 11 clamp the workpiece 8.
