The following detailed description is made in accordance with embodiments illustrated in the drawings as follows:

as shown in fig. 1-4, a center fine-tuning vise structure is disclosed, comprising: a vise body 1 having a guide groove 11. A lead screw positioning seat 2, which is disposed at the center of the guiding groove 11 and has a lead screw positioning groove 21. A guiding screw 3, the center of which is provided with a positioning part 31, the positioning part 31 is positioned at the screw positioning groove 21, and two sides of the positioning part 31 are respectively provided with a positive external spiral thread 32 and a reverse external spiral thread 33. And a clamping seat module 4 slidably disposed in the guide groove 11 of the vise body 1, wherein the clamping seat module 4 includes a first movable clamping jaw set 41 and a second movable clamping jaw set 42, the first movable clamping jaw set 41 has a regular internal spiral thread 411 disposed corresponding to the regular external spiral thread 32 of the lead screw 3, the second movable clamping jaw set 42 has a reverse internal spiral thread 421 disposed corresponding to the reverse external spiral thread 33 of the lead screw 3, so that the first movable clamping jaw set 41 and the second movable clamping jaw set 42 can simultaneously clamp or simultaneously loosen when the lead screw 3 rotates. At least one long through hole 12 parallel to the lead screw 3 is respectively penetrated through the front and rear ends of the vise body 1, an adjusting rod 5 is disposed in the long through hole 12, and the adjusting rod 5 includes a first end 51 for adjusting the front and rear displacement of the adjusting rod 5 and a second end 52 capable of pushing the lead screw positioning seat 2 to move for center adjustment. The front and rear ends of the lead screw positioning seat 2 corresponding to the second end 52 are respectively provided with a groove 22 capable of abutting against the second end 52 of the adjustment rod 5.

Wherein, through the matching of the second end 52 of the adjusting rod 5 and the groove 22 of the lead screw positioning seat 2, when the second end 52 is pressed toward the groove 22, the lead screw positioning seat 2 can be pulled down to be tightly combined with the vice body 1, so as to achieve the effect of fixing without screws, and the operation of the adjusting center can be more effectively and quickly completed, thereby greatly improving the working efficiency and increasing the production, and having the improvement of the effect.

Next, referring to fig. 3, if the center position of the center vise needs to be adjusted finely, the operation mode is to loosen the adjusting rod 5 on one side, screw lock the adjusting rod 5 on the other side to push the lead screw positioning seat 2 to move to the required center position, and finally lock one of the adjusting rods 5 to complete the operation of adjusting the center, so as to easily complete the center positioning of the vise, thereby achieving the effects of simply, conveniently, and reliably ensuring the center alignment accuracy.

In the above, the adjusting rod 5 further includes a top rod 53 disposed in the long through hole 12 and having one end abutting against the lead screw positioning seat 2, and a screw 54 disposed at the other end of the top rod 53 for adjusting the front and rear displacement of the top rod 53, wherein the top rod 53 and the screw 54 can be integrally formed or non-integrally formed.
