Description

Positioning internal support mechanism for front end of front axle plate Technical Field The utility model belongs to the technical field of forklift assembly, and particularly relates to a positioning internal bracing mechanism for the front end of a front axle plate of a forklift frame. Background The forklift frame is of a box type structure and is formed by welding steel plates, and mainly comprises a left front axle plate, a right front axle plate, a reinforcing plate, supporting legs, a chassis and the like. The front end of the forklift frame is rigidly fixed on the drive axle, the rear end of the forklift frame is connected with the steering axle through a winch shaft, and the supporting legs and the chassis are assembled and welded to form an integral frame. Before welding and assembling, the front axle plate needs to be positioned and then welded and assembled with a chassis or a supporting leg part of the frame. The existing clamping mode is to fix the head and tail of the forklift frame on the head and tail positioning tool of the positioner respectively. The front end positioning mode of the front bridge plate adopts a clamping device to position at present, the structure of the clamping device is shown in fig. 1, the clamping device 1 comprises a base 11, two positioning headstock 12 symmetrically and slidably arranged on the base 11 and a positioning shaft 13 fixedly arranged on the positioning headstock, when the front bridge plate is positioned, the arc-shaped surfaces of the left and right front bridge plates 2 are clamped on the corresponding positioning shafts 13, and then the left and right positioning headstock 12 moves towards the middle to clamp the front bridge plate. However, in this positioning manner, since the inner side of the front axle plate is not effectively limited, after the welding of the forklift frame is completed, the left and right front axle plates will have inward deformation trend and error will occur when connected with the driving axle, so that the front axle plate still needs to be corrected manually after welding. The special tooling mechanism can be integrated into the original position-changing machine head tooling, can quickly and effectively realize the internal bracing effect on the left and right front axle plates of the frame, prevents the front axle plates from deforming inwards during welding, avoids post-welding correction, and reduces the labor intensity. Disclosure of utility model In order to solve the problem of deformation of the front axle plate, the utility model provides a positioning inner supporting mechanism at the front end of the front axle plate. The front axle plate can be limited simultaneously in the outer and inner sides of the front axle plate, deformation of the front axle plate during welding is prevented, post-welding correction is avoided, and labor intensity is reduced. The technical scheme of the utility model is as follows: the utility model provides a bracing mechanism in location of front axle board front end, includes clamping device, clamping device is including being used for carrying out a set of locating headstock of centre gripping to left and right front axle board front end, still includes interior support device, interior support device includes the connection support with clamping device fixed connection, the connection support rotation is connected with interior support lead screw, the both ends of interior support lead screw are threaded connection respectively has interior support piece, rotates interior support lead screw and makes two interior support pieces move in opposite directions or dorsad, and interior support piece and the locating headstock that is located same one end carry out inside and outside centre gripping location to a front axle board front end together. Further, the connecting support comprises a mounting seat provided with a through hole, the inner supporting screw rod is mounted in the through hole through a bearing and rotates freely in the through hole, two connecting arms are mounted on the mounting seat and are in V-shaped structures, and connecting plates fixedly connected with the clamping devices are fixedly arranged at the tail ends of the connecting arms. Further, a limiting piece for preventing the inner support screw rod from moving along the axial direction is arranged on the inner support screw rod positioned in the through hole. Preferably, the limiting piece comprises a spacer bush and a lock nut, and the spacer bush is positioned between the lock nut and the bearing. Further, the inner support piece is provided with an anti-rotation guide rod for preventing the inner support piece from rotating. In a further scheme, the anti-rotation guide rod is arranged parallel to the inner support screw rod, one end of the anti-rotation guide rod is inserted into the inner support member, and the other end of the anti-rotation guide rod is inserted into the guide rod fixing piece arra
