[0023] Please see Figures 1 to 4 This utility model provides an embodiment of a vise clamp with center positioning assistance, comprising a base 10, on which a clamping assembly 20 and a center positioning assembly 30 are provided. The clamping assembly 20 is used to clamp and fix the workpiece, while the center positioning assembly 30 is used to assist in center positioning of the workpiece. The center positioning assembly 30 includes a center positioning insert 31 and a center positioning pin 32. The center positioning insert 31 has a mounting groove 33 at its top center position, and the center positioning pin 32 is inserted into the mounting groove 33 from top to bottom. The side end of the center positioning insert 31 has a threaded through hole 3 that communicates with the mounting groove 33. 4. An adjusting bolt 35 is internally threaded into the threaded through hole 34. The adjusting bolt 35 tightens the center positioning pin 32 from the outside in. The top of the center positioning pin 33 is tapered. The bottom of the processed product is provided with a tapered hole that matches the shape of the center positioning pin 32. The center positioning pin 32 can slide up and down in the mounting groove 33 and is locked in place by the adjusting bolt 35 and the threaded through hole 34 to achieve the effect of adjusting the height. The center positioning pin 32 can tighten against the tapered hole reserved at the bottom of the processed product and clamp the processed product through the clamping assembly 20 to fix the product after auxiliary center positioning, further improving the processing accuracy.

[0024] The center positioning component 30 is also provided with several fixing bolts 36. The base 10 is provided with a through hole 11 through which the fixing bolts 36 can pass. The bottom of the center positioning insert 31 is provided with a threaded hole 37 that is compatible with the fixing bolts 36. The fixing bolts 36 pass through the through hole 11 from bottom to top and are threadedly connected to the threaded hole 37, thereby realizing the fixed connection of the center positioning insert 31 to the base 10.

[0025] The center positioning insert 31 has a through hole 38 through which the fixing bolt 36 can pass. The base 10 has a threaded hole 12 that matches the fixing bolt 36. The fixing bolt 36 passes through the through hole 38 from top to bottom and is threaded into the threaded hole 12, which further improves the fixing connection effect of the base 10 of the center positioning insert 31.

[0026] The base 10 is provided with two positioning grooves 13. The two ends of the central positioning insert 31 are adapted to the structure of the positioning groove 13. The two ends of the central positioning insert 31 are embedded into the positioning groove 13 from top to bottom. The second through hole 38 is located at both ends of the central positioning insert 31, while the second threaded hole 12 is located in the two positioning grooves 13 respectively.

[0027] In this embodiment, the mounting groove 33 is a cylindrical groove extending downward from the top surface of the central positioning insert 31, and the central positioning pin 32 can slide up and down along the mounting groove 33 to ensure vertical height adjustment.

[0028] The clamping assembly 20 includes a transmission screw 21, two movable jaws 22, and two clamping grippers 23. The base 10 is provided with a sliding groove 14 that is adapted to the movable jaws 22. The two movable jaws 22 are movably connected to the sliding groove 14. Both ends of the transmission screw 21 are provided with adjusting external threads 24, which are threadedly connected to the two movable jaws 22 respectively. The two clamping grippers 23 are detachably installed to the two movable jaws 22 respectively. When the transmission screw 21 rotates, the two clamping grippers 23 move synchronously towards each other or open, generating clamping force. The two clamping grippers 23 clamp the two sides of the processed product, thus playing a clamping role.

[0029] The clamping assembly 20 also includes mounting bolts 25. The clamping gripper 23 has a through hole 26 extending longitudinally through it. The movable jaw 22 has a threaded hole 27 that matches the mounting bolts 25. The mounting screw 25 passes through the through hole 26 from top to bottom and is threaded into the threaded hole 27, thereby enabling the movable jaw 22 and the clamping gripper 23 to be detachably installed. The movable jaw 22 and the clamping gripper 23 can be detachably installed by at least two or more mounting bolts 25.

[0030] The movable jaw 22 is provided with a cross positioning groove 28 at the top, and the gripping hard gripper 23 is provided with a positioning protrusion (not shown) at the bottom that matches the shape of the cross positioning groove 28. The positioning protrusion is inserted into the cross positioning groove 28. This structure allows the movable jaw 22 and the gripping hard gripper 23 to be quickly and accurately positioned and aligned, which facilitates user installation and improves gripping accuracy.

[0031] A clearance structure is provided between the center positioning insert 31 and the base 10, wherein the transmission screw 21 passes through the clearance structure, which can ensure that the transmission screw 21 can rotate freely.

[0032] The base 10 is disc-shaped and has several evenly arranged mounting holes 15. The disc-shaped base 10 can be quickly aligned with the rotating disc of the machine tool and installed by bolts passing through the mounting holes 15, which facilitates the use of the tiger clamp with the machine tool.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
