At this time, the positioning blocks 4 are basically attached to the upright posts of the side wall frame, and if the positioning blocks 4 which are not partially attached to the upright posts exist, the positioning blocks 4 can be moved transversely or longitudinally on the second support frame 3 to finely adjust the positions of the positioning blocks. Meanwhile, the height of the positioning block 4 can be adjusted by matching the first plate body 401, the second plate body 402 and the bolt assembly 403, so that the side wall framework can be fixed better, and the subsequent operation of workers can be facilitated.
To sum up, this application has adopted the modularized design structure, modularizes whole frock, and every first support frame 2 and the equal independent function of second support frame 3 realize the location locking function, can mutually support again each other, realize whole linkage function, accomplish the whole spacing function of offside skeleton, accommodation process, simple, swift, it is suitable for extensively, can satisfy the demand of multiple motorcycle type side wall skeleton preparation, effectively reduced frock manufacturing cost, reduced operation personnel's intensity of labour. In addition, this application practicality is strong, can avoid the material cost input of repeated preparation frock, has practiced thrift material and cost of labor, can show the positioning accuracy who improves side wall skeleton, effectively restraines defects such as side wall skeleton assembly welding deformation, has promoted the processingquality of product.
