DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The following describes the present invention in detail with the best embodiments.

[0014] As Figure 1 shown, a combined tooling structure for the suspension truss of a double-joint crawler vehicle includes a support platform 1, a left base 2, a left bracket 3, a left moving slider 4, a left positioning fixture 5, a right base 6, a right bracket 7, and a right moving slider 8; the left base 2 and the right base 6 are respectively arranged on the left and right sides of the support platform 1. There are T-shaped grooves 1-1 on the support platform 1, and guide rails matching the T-shaped grooves 1-1 are provided at the bottoms of the left base 2 and the right base 6, and the T-shaped grooves play a guiding role. A scale is provided on the support platform to facilitate the memorization of the positions of the left and right devices.

[0015] The left base 2 and the right base 6 are respectively fixed with a left support 3 and a right support 7; a left moving slide 4 is installed on the left support 3, and a sliding fit is realized between the left moving slide 4 and the left support 3 through a guide rail and a T-shaped groove, that is, a sliding fit structure formed by arranging a T-shaped groove on the left support 3 and a guide rail on the left moving slide 4; a rack 4-2 is further arranged on the left moving slide 4, and a gear mechanism is arranged inside the left support 3, and the gear of the gear mechanism meshes with the rack 4-2, and the gear mechanism is manually operated to realize the movement of the left moving slide 4; a left positioning fixture 5 is installed at the end of the left moving slide 4.

[0016] A right moving slide 8 is installed on the right support 7, a right positioning fixture 9 is installed on the right moving slide 8, and the structures of the right base 6, the right support 7 and the right moving slide 8 are the same as those of the left base 2, the left support 3 and the left moving slide 4 but in the opposite direction.

[0017] Both the left positioning fixture 5 and the right positioning fixture 9 are composed of an elastic shaft 10 and a spline shaft 11.

[0018] The elastic shaft 10 and the spline shaft 11 on the right moving slide 8 are opposite to the elastic shaft 10 and the spline shaft 11 on the left moving slide 4, and the left spline shaft and the right elastic shaft are concentric, and the right spline shaft and the left elastic shaft are concentric.

[0019] During use, the left and right moving slides are moved to appropriate positions and fixed according to the size of the suspended truss to be processed. The left and right moving slides are respectively provided with scales for facilitating the memory of the positions of the left and right slides; the movement of the left and right slides is realized by manually operating the gear to drive the rack to roll and being guided by the guide rail. The device fixes the left and right moving slides on the left and right supports respectively through the T-shaped groove. The welded part "suspended truss" is installed on the left and right positioning fixtures for welding operations. The positioning fixtures are composed of an elastic shaft and a spline shaft, and the left spline shaft and the right elastic shaft are concentric, and the right spline shaft and the left elastic shaft are concentric; the concentric adjustment is completed by the adjustment pads between the base and the support during the assembly of the equipment; after the welding is completed, the "crawler vehicle suspended truss" that has been welded into one body is unloaded.

[0020] Through repeated operations of the suspended truss combined tooling, the welding assembly of the "suspended truss of the crawler vehicle" can be repeatedly combined, greatly shortening the production cycle. The completed "suspended truss" assembly can be directly combined to the vehicle body position by welding without further machining.
