[0017] The utility model is further described below with reference to the accompanying drawings and embodiments. Embodiment 1

[0018] Reference Figure 1-2 As shown, a clamping assembly suitable for mouth-shaped tooling includes a plurality of fixing bolts 1 and two symmetrically arranged clamping members, wherein the outer diameter of the bolt head 101 of the fixing bolt 1 is larger than the outer diameter of the rod body 102, and the clamping member includes a clamping platform 3, on which a plurality of positioning holes 301 adapted to the rod body 102 of the fixing bolt 1 are provided, and a vertical mounting portion 4 is provided on the inner side of the bottom thereof; the mounting portion 4 is provided with bolt holes 401 corresponding to the screw holes of the vise jaws, and the fixing bolt 1 is inserted into the positioning hole 301.

[0019] When in use, firstly, two clamping parts are respectively installed on the jaws of the two sides of the bench vise by bolts, and the bench vise is operated to separate the two parts by a distance, and then the die plate or pre-die 7 is placed in the middle position of the two clamping platforms 3, and then a plurality of fixing bolts 1 are inserted into the corresponding positioning holes 301 along the outer contour of the to-be-clamped parts, and finally the bench vise is operated to bring the two clamping parts closer together, and the to-be-clamped parts are firmly clamped by the plurality of fixing bolts 1; Figure 3 Figure 4 These are respectively the clamping states of the circular die plate 6 and the pre-die plate 7 of the device, and it can be seen that the distribution of the fixing bolts 1 is different.

[0020] The device can firmly clamp the mouth plates or pre-mouth shapes 7 of different shapes through the cooperation of the fixing bolt 1 and the positioning holes 301 in different positions, avoid the precision defects caused by sliding, achieve the operation accuracy more quickly, and reduce the potential safety hazards, making the operation process safer and more reliable; the tool takes into account the clamping needs of workpieces of various specifications and shapes, improves the versatility of the design, and greatly improves the practicality.

[0021] In more detail, the plurality of positioning holes 301 are divided into multiple rows on the clamping platform 3, and the hole pitch of the inner row is smaller than the hole pitch of the outer row; when a smaller combined die plate needs to be clamped, the positioning holes 301 in the inner row can be selected to cooperate with the fixing bolts 1 for clamping. Embodiment 2

[0022] As a preferred embodiment of the utility model, this embodiment adds a rubber sleeve 2 on the basis of the first embodiment, specifically:

[0023] In this embodiment, a rubber sleeve 2 is sleeved on the rod body 102 of the fixing bolt 1, and the outer diameter of the rubber sleeve 2 is slightly larger than the aperture of the positioning hole 301. When the fixing bolt 1 is inserted, the setting of the rubber sleeve 2 can make the fixing bolt 1 and the positioning hole 301 cooperate more firmly, thereby further improving the clamping stability of the device. Embodiment 3

[0024] As a preferred embodiment of the utility model, this embodiment is additionally provided with a clamping plate 5 on the basis of the second embodiment, specifically:

[0025] In this embodiment, a vertical clamping plate 5 is provided on the top outer side of the clamping platform 3. Figure 5 As shown, when the square mouth plate 8 needs to be clamped, the clamping plate 5 on the top of the clamping platform 3 can be used to clamp it.
