Detailed Description

As shown in the figure, the utility model provides an assembly fixture of unmanned helicopter sled formula undercarriage, including the supporting bench 4 that is used for centre gripping sled formula undercarriage bow beam 1 and the fixed subassembly 5 that is used for fixed skid 2, fixed subassembly sets up in skid 2 and the corresponding assembly position of bow beam 1. Wherein skid 2 and bow-shaped roof beam 1 are through connecting piece 3 fixing bolt assembly that punches on the frock, and connecting piece 3 pre-installation is on skid 2. Therefore, the skid type undercarriage is assembled in batches by fixing the undercarriage arched beam on the support table, fixing the skid on the fixing assembly, adjusting the position of the skid to the assembling position corresponding to the two ends of the arched beam and fixing the fixing assembly.

In this embodiment, two ends of the top of the arched beam 1 are correspondingly provided with a support seat 401 for fixing the arched beam. As shown in the figure, the supporting seat is of an I-shaped structure, two ends of a transverse main rod are respectively provided with a longitudinal branch rod, and the arched beam character-shaped positions are arranged on the branch rods at the two ends. The support table 4 is located at the top of the arched beam and provided with a symbol-shaped support seat 401, and the arched beam can be supported through the support seat, so that subsequent assembly work is facilitated.

In this embodiment, the supporting base 401 is disposed on the supporting base 405 through two upright supporting pillars 404. As shown in the figure, the supporting seat is fixed on the supporting base through the upright supporting column, so that a supporting platform is formed integrally, the supporting column can be supported by a whole square column, and the supporting seat can also be supported at a stress point by two square columns in the figure. The form adopted in the embodiment can reduce the material utilization and simultaneously lighten the weight of the device.
