The fixed of each assembly is provided with locating slot using bolts assemblies positioning on platform, be capable of achieving the assembling without adjustment, is easy to each car
Type it is general.Each assembly can be also arranged in precise guide rail, adjusted with HYDRAULIC CONTROL SYSTEM and positioned, it is adaptable to wider car
Molded dimension.
For the ease of description, with Platform center as origin, stand in origin, be Z axis positive direction with direction straight up, with
Direction is X-axis positive direction where the propons of vehicle, to be Y-axis positive direction towards left hand direction during propons.
Such as Fig. 2-3, specifically, the propons locating support assembly 1 is used to limit the front and back position and right position of propons,
Propons locating support assembly 1 includes the first support body 15, two oblique location-plates 13 being fixed on the first support body 15 and by axle
Hold on the first support body 15 spacing roller 12.The V-shaped location structure of described two oblique location-plates 13, i.e., two tiltedly position
, more than distance between lower edge, two oblique location-plates 13 can neither be too with the angle of horizontal plane for the distance between top edge of plate 13
Greatly, can not be too small, angle is too small, and tire is easily moved forward and backward, and angle is too big, and oblique location-plate 13 cannot play support tire
Effect；Described two oblique location-plates 13 are symmetrical on a perpendicular, and the perpendicular is parallel with ZOY planes.The limit
Position roller 12 is located at two outsides of oblique location-plate 13, so that two spacing rollers 12 are produced to two tire lateral surfaces respectively
Squeezing action, the spacing roller 12 can also be located at two inner sides of oblique location-plate 13, so that two 12 points of spacing rollers
It is other that two tire medial surfaces are produced with squeezing actions, spacing roller 12 can also be located at simultaneously two outsides of oblique location-plate 13 with
Outside；The spacing roller 12 is consistent with X-direction, and the interactively of tire and mold is turned into linear contact lay by the design of roller,
Rolling friction replaces Dry Sliding, by rolling at whereabouts side adjustment, can effectively solve dropping process in because of rubber
Power is uneven caused by excessive with support coefficient of friction, and then influence is accurately positioned problem.It is furthermore preferred that spacing roller 12 has
Elastic pre-stress, is easy to eliminate bridge error；The structure of back axle locating support assembly 2 and the structure phase of propons locating support assembly 1
Together；, on XOZ plane symmetries, two back axle locating support assemblies 2 are on XOZ planes for described two propons locating support assemblies 1
Symmetrically.
Preferably, by adjusting position of the spacing roller 12 in Y-axis, thus between adjusting the inner side of spacing roller 12 away from
From realizing the production between different wheelspan vehicles, including but not limited to following structure type：The two ends of spacing roller 12 pass through axle
Hold and be separately mounted on base, can be adjusted spacing by way of increasing or reducing backing plate between base and the first support body
Position of the roller 12 in Y-axis.
The V-structure of two swash plate compositions defines two front and back positions of front-wheel on each propons locating support assembly 1,
Along with two spacing rollers 12 are respectively to tire medial surface or the squeezing action of lateral surface, the left and right position of tire is defined
Put, so that all around center of the dropping process of wheel with regard to energy automatic capturing propons, directly eliminates front axle main pin flare
Angular difference, excludes the deviation that stub difference is caused；The same propons of back axle positioning principle.
By propons locating support assembly 1 and back axle locating support assembly 2, the cornerwise positioning of wheelbase can be once realized,
Finally realize being accurately positioned for wheelbase.By adjusting the center between propons locating support assembly and back axle locating support assembly
Away from realizing the production between different wheelbase vehicles.The combination of including but not limited to following two modes or two ways：
First, it is also detachable on the preceding oblique location-plate and/or the location-plate that retreads of the oblique location-plate 13 of the propons locating support assembly 1
1-n layers of backing plate 11 is fixed with, n is natural number, and the backing plate 11 is parallel with oblique location-plate 13；If the front and back position of front-rear axle is needed
Adjust, lifted vehicle bridge with jack, the backing plate on front side of wheel is moved to wheel rear side, or by the backing plate on rear side of wheel
It is moved to wheel front side.By way of adding and subtracting backing plate, the accurate symmetrical adjustment of front-rear axle wheelbase is realized, while not influenceing propons
Height and position, it is ensured that wheelbase and cornerwise accuracy and uniformity.Back axle locating support assembly 2 can also equally be set.
Backing plate can realize the fine setting of wheelbase.
