[0027] The embodiment of the present application discloses a hydraulic automatic clamping welding tool for a boom truck chassis, comprising: a hydraulic clamping assembly 1, a shooting switch 3 and a hydraulic centering slide 2.

[0028] Among them, there are two sets of welding tooling, which are respectively fixed on the head and tail frame positioners; the hydraulic clamping assembly 1 and the shooting switch 3 are both fixedly installed on the hydraulic centering slide 2, the hydraulic clamping assembly 1 is used to clamp the chassis workpiece up and down, the hydraulic centering slide 2 is used to clamp the chassis workpiece horizontally, and the shooting switch 3 detects whether the chassis workpiece is in place.

[0029] The welding tooling of the present application detects whether the chassis workpiece is in place by setting a shooting switch 3, thereby realizing the automation of the chassis workpiece clamping and improving production efficiency; by setting a hydraulic clamping assembly 1 and a hydraulic centering slide 2 to clamp the upper and lower and horizontal positions of the chassis workpiece respectively, the positioning accuracy of the chassis workpiece is effectively guaranteed, thereby ensuring the welding quality of the chassis workpiece.

[0030] In some embodiments, for example Figure 2 As shown, the hydraulic clamping assembly 1 includes an assembly body 11, a support seat 12, a wear-resistant plate 13, a clamping plate 14 and a hydraulic cylinder 15; the assembly body 11 includes a vertical plate and a horizontal plate, the support seat 12 is installed on the vertical plate, the hydraulic cylinder 15 is installed on the horizontal plate, the hydraulic cylinder 15 is vertically arranged above the support seat 12, the wear-resistant plate 13 is laid on the support seat 12, and the clamping plate 14 is connected to the end of the telescopic rod of the hydraulic cylinder 15, and is opposite to the wear-resistant plate 13 up and down.

[0031] The support seat 12 is fixed, the wear-resistant plate 13 is laid on the support seat 12, and the clamping plate 14 is connected to the lower end of the hydraulic cylinder 15. When the chassis workpiece is clamped, the hydraulic cylinder 15 drives the clamping plate 14 to move downward to clamp the chassis workpiece between the wear-resistant plate 13 and the clamping plate 14.

[0032] Furthermore, the hydraulic clamping assembly 1 also includes a bushing 16 and a guide rod 17. There are two bushings 16 and two guide rods 17 respectively. Through holes are provided on the horizontal plates on both sides of the hydraulic cylinder 15. The two bushings 16 are respectively installed in the two through holes. The lower ends of the two guide rods 17 are connected to the clamping plate 14, and the upper ends of the two guide rods 17 pass through the two bushings 16 respectively.

[0033] The provision of the guide rod 17 can guide the lifting and lowering of the pressing plate 14 to prevent the pressing plate 14 from deflecting, and at the same time, can also make the lifting and lowering of the pressing plate 14 more stable and smooth.

[0034] In some embodiments, for example Figure 3 and Figure 4 As shown, the hydraulic centering slide 2 includes a slide body 21, a bracket slide 22, a screw 23, a bearing seat 24, a nut seat 25, a nut 26 and a hydraulic motor 27; the hydraulic motor 27 is installed at one end of the slide body 21, and the bearing seat 24 is installed at the other end of the slide body 21.

The two support slides 22 connected to the nut holders 25 also move synchronously in opposite directions, with guide rails 28 providing guidance and support. Ultimately, the two support slides 22 adjust to the proper position and clamp the head and tail of the chassis workpiece, achieving complete horizontal positioning of the chassis workpiece. After welding is complete, hydraulic motor 27 activates, driving the two support slides 22 in opposite directions. When the slides contact the travel switch 4, the hydraulic centering slide 2 stops.

[0036] Furthermore, the hydraulic centering slide 2 further includes a guide rail 28 and a guide rail 28 slider. The guide rails 28 are provided on both sides of the slide body 21, and the bracket slide 22 is slidably fitted on the guide rail 28 through the guide rail 28 slider. This can make the movement of the bracket slide 22 more stable and smooth.

[0037] Furthermore, the hydraulic centering slide 2 further includes a travel switch 4 . Two travel switches 4 are provided. The two travel switches 4 are respectively provided at both ends of the slide body 21 . The travel switches 4 are used to control the hydraulic centering slide 2 to stop.
