Therefore, these and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and descriptive purposes only and not for purposes of indication or implication as to the relative importance of the respective components.

Referring to fig. 1, a schematic structural diagram of a welding tool according to an embodiment of the utility model is shown. Welding frock is as the appurtenance with the nut location on the cell-phone medium plate in advance welding position department, this welding frock is including setting firmly the processing platform 2 at a supporter structure 1's top, this supporter structure 1 can be platform or support body, and possess certain levelness, it is as making the base that processing platform can be put by the level, processing platform 2 is last to have arranged at least one fixed plate 3 that is used for fixed cell-phone medium plate 8, processing platform 2 also possesses certain levelness, so that the cell-phone medium plate 8 of placing above that can keep the level.

The processing platform 2 further has a clamping body 4 for positioning the nut 9, the clamping body 4 is operatively mounted on the fixed plate 3, the mobile phone middle plate 8 is located between the clamping body 4 and the fixed plate 3, and the clamping body 4 is provided with a plurality of grooves 41, and the grooves 41 have a shape matched with the nut 9. Specifically, the mobile phone middle plate 8 is fixed on the processing platform 2, the clamping bodies 4 are placed on the upper surface of the mobile phone middle plate 8, the grooves 41 in the clamping bodies 4 are aligned with the pre-welding positions on the mobile phone middle plate 8 one by one, then the nuts 9 can be placed in the grooves 41, the nuts 9 are located at the pre-welding positions, time for calibrating the welding positions of the nuts is shortened, and finally the nuts in the grooves are welded on the upper surface of the mobile phone middle plate through welding equipment.

In order to further ensure the accuracy of the position of the nut in the welding process, a plurality of elbow clamp mechanisms 5 are further arranged on the fixing plate 3, the nut 9 positioned in the groove 41 can be respectively and tightly attached to the mobile phone middle plate 8 on the fixing plate 3 through the elbow clamp mechanisms 5, so that the transverse movement of the nut 9 is limited by the groove 41 in the welding process, and the bouncing of the nut 9 is limited by the elbow clamp mechanisms 5.

Referring to fig. 3, the toggle clamp mechanism 5 includes a toggle clamp holder 51, and a lower portion of the toggle clamp holder 51 is rotatably mounted to the stationary plate 3; a spanner 52 is arranged at the top of the toggle clamp seat 51, an elbow clamp arm 53 is formed by extending outwards towards one side at the middle part of the toggle clamp seat 51, and the front end of the elbow clamp arm 53 is provided with a downward pressing part 531; the middle of the toggle clamp seat 51 extends outward to form a mounting portion 54, it should be noted that the mounting portion 54, the toggle clamp arm 53 and the toggle clamp seat 51 form a three-axis space structure, in addition, the mounting portion 54 has a downwardly protruding limiting post 541, the lower portion of the limiting post 541 is preferably designed into a sphere shape, and a concave limiting groove 33 is disposed at a corresponding position on the fixing plate 3. Specifically, the elbow clamping seat 51 is rotated by the wrench 52 until the lower portion of the limiting post 541 is clamped into the limiting groove 33, at this time, the elbow clamping seat 51 is rotated by just 90 degrees, and the elbow clamping arm 53 is stopped above the clamping body 4, and meanwhile, the bottom end of the pressing portion 531 is in contact with the nut 9 and applies a downward acting force to the nut 9, so that the nut 9 in the groove 41 is tightly attached to the pre-welding position on the mobile phone middle plate 8, and it is ensured that the nut cannot be shifted during the welding process.

It is to be considered that, in order to facilitate the nut 9 to be placed in the groove 41 and to enable the pressing portion 531 to smoothly move downward from above the groove 41 to be in contact with the nut 9, the groove 41 is configured such that its diameter is gradually reduced from top to bottom.

Furthermore, in order to avoid the situation that the pressing portion 531 is separated from the nut 9 due to the bottom end of the position-limiting post 541 accidentally slipping out of the position-limiting groove 33, the toggle clamp holder 51 can be kept in the vertical state by a movable pushing body 6 when the toggle clamp mechanism is rotated until the position-limiting post is engaged in the position-limiting groove, that is, the pushing body 6 is used to prevent the toggle clamp holder 51 from rotating reversely, and the pushing body 6 performs displacement motion through a cylinder assembly 7.
