Detailed Description

The principles and features of the present invention will be described with reference to the accompanying fig. 1 to 5, wherein the examples are provided only for explaining the present invention and are not intended to limit the scope of the present invention.

A special pneumatic tool for assembling and welding a front longitudinal beam of a frame comprises a rack 1, an auxiliary adjusting assembly 6, a positioning block 2, a driving assembly 13, a clamping block 3 and a supporting block 4. In this embodiment, six auxiliary adjustment assemblies 6, six positioning blocks 2, five drive assemblies 13 and five clamping blocks 3 are used, respectively.

The rack 1 is provided with a guide rail 9, the auxiliary adjusting assembly 6 and the positioning block 2 are arranged in a row, and the arrangement direction of the auxiliary adjusting assembly is the same as the extension direction of the front longitudinal beam 5 to be welded. Specifically, the auxiliary adjusting assembly 6 includes a base 7 and a screw 8, wherein the base 7 includes a horizontal portion 10 and a vertical portion 11 which are integrally formed. The horizontal part 10 is connected with the guide rail 9 in a sliding mode, and the screw 8 is in threaded connection with the vertical part 11. One end of the screw rod 8 is fixedly connected with the positioning block 2. The auxiliary adjusting assembly 6 slides along the guide rail 9 and the relative position of the screw 8 and the base 7 is adjusted, so that the positioning of front longitudinal beams to be welded in different models can be realized. In order to ensure the accuracy of the positioning of all the positioning blocks 2, a laser sensor 12 is provided on the vertical portion 11 for detecting the distance between the positioning blocks 2 and the vertical portion 11. A part of the upper surface of the horizontal portion 10 is an auxiliary positioning surface, such as the surface a in fig. 4, which is perpendicular to the positioning surface of the positioning block 2. When welding, the top beam of the front longitudinal beam needs to be placed on the auxiliary positioning surface and tightly attached to the positioning surface of the positioning block 2.

The driving assembly 13 and the clamping blocks 3 are aligned in a row in the same direction as the extension direction of the front longitudinal beam 5 to be welded. In particular, the drive assembly 13 comprises a bracket 14, a driver 15, a transmission rod 16 and a sleeve 17. Wherein the support 14 is fixed on the gantry 1 and the driver 15 is a pneumatic motor and is fixed on the support 14. The output end of the driver 15 is connected with a transmission rod 16, the surface of the transmission rod 16 is provided with an external transmission thread, the inner wall of the sleeve 17 is provided with an internal transmission thread, and one end of the transmission rod 16 extends into the sleeve 17. The sleeve 17 is connected with the bracket 14 in a sliding mode, and the transmission rod 16 can drive the sleeve 17 to move back and forth in a forward rotation mode or a reverse rotation mode. The clamping block 3 is fixedly connected to the tail end of a sleeve 17, and the sleeve 17 moves to drive the clamping block 3 to be close to the positioning block 2 so as to clamp a workpiece to be welded.
