A support rod 32 is provided on the end face of the support plate 31 away from the sliding rod 24. In this embodiment, the support rod 32 is preferably a semi-circular rod. The support rod 32 is fixedly connected to the fixed tube 24 by screws.

[0049] Reference Figure 1 and Figure 4 The bonding device 3 also includes mounting plates 33. There are two mounting plates 33, which are located on both sides of the axis of the support rod 32. The mounting plates 33 are elastically hinged to the support rod 32 by means of torsion springs.

[0050] Reference Figure 1 and Figure 4 The mounting plate 33 has a sliding groove 331 on the side wall away from the support plate 31 in the vertical direction. The mounting plate 33 has an adjustment groove 332 on the top wall of the sliding groove 331, and the inner cavities of the sliding groove 331 and the adjustment groove 332 are connected.

[0051] Reference Figure 1 and Figure 4The bonding device 3 includes multiple abutment components 34. Each abutment component 34 includes a mounting rod 341 and a holding block 342. The mounting rod 341 is vertically arranged and located in the sliding groove 331. The mounting rod 341 can slide along the long side of the sliding groove 331.

[0052] Reference Figure 1 and Figure 4 Multiple springs 343 are provided on the end face of the mounting rod 341 away from the sliding rod 24. The springs 343 are arranged at intervals along the axial direction of the mounting rod 341. In this embodiment, the extension and contraction direction of the springs 343 is perpendicular to the plane of the mounting plate 33.

[0054] The implementation principle of the highly adaptable positioning fixture of this application is as follows: the operator first rotates the adjusting bolt 121 to keep the support frame 11 horizontal, and the setting of the friction pad 124 enables the support frame 11 to be stably fixed to the relevant structure of the machine.

[0055] The operator then rotates the fixed tube 22, positioning the lung cavity in different positioning slots 212, thereby providing a certain positioning effect for the angle of the fixed tube 22 and preventing the fixed tube 22 from rotating. The servo motor 251 drives the worm gear 252 to rotate, and the worm gear 252 meshes with the worm wheel 253, which in turn causes the gear 254 to rotate. The gear 254 drives the rack 255 to slide, thereby pushing out the sliding rod 24.

[0056] The support plate 31 approaches the workpiece, and at the same time, the mounting plate 33 rotates along the support rod 32. The gripping block 342 drives the mounting rod 341 to slide along the sliding groove 331 to a suitable position, continuously bringing the moving rod closer to the workpiece. The ground spring 343 rotates along the mounting rod 341 to a certain extent, and the bonding plate 344 and the contact pad 345 are attached to the side wall of the workpiece, thus completing the limitation and fixation of the workpiece and preventing the workpiece from shaking during the processing, which would affect the positioning effect of the workpiece.
