Embodiment 1

[0019] Such as figure 1 and 2 As shown, the lifting platform provided on the positioner provided in this specific embodiment includes a rotatable operating platform 5 connected to the positioner 1 and a plurality of liftable platforms for supporting the operating platform 5 to always meet the work requirements. Supporting mechanism, when the angle between the operating platform 5 and the horizontal plane is not greater than 5°, it meets the work requirements. The supporting mechanism is hinged to the lower end of the operating platform 5. Multiple supporting mechanisms are distributed on both sides of the positioner 1. 1 is raised or lowered to lift, when the positioner 1 is lifted or dropped, the operation platform 5 rotates around the connection point between the operation platform 5 and the positioner 1 under the action of the supporting mechanism to maintain the operation platform 5 always in line with the horizontal plane The included angle is not greater than 5°.

Embodiment 2

[0028] In this specific embodiment, another lifting platform provided on the positioner is provided. The lifting platform provided on the positioner provided in this specific embodiment is basically the same as the lifting platform provided on the positioner provided in Embodiment 1. The same, but the difference is: the support mechanism in this specific embodiment is an oil cylinder, and there are two oil cylinders. The hinge points of the positioner and the operation platform are not located on the same straight line. This setting realizes three non-collinear points supporting the operation platform to realize the stability of the operation platform. When the positioner is lifted or lowered, the two oil cylinders supporting the operation platform are simultaneously Action, extension or contraction, when the operation platform is lifted or dropped by the positioner, the operation platform rotates around the hinge point of the operation platform and the positioner under the act...

Abstract

The invention discloses a lifting platform arranged on a positioner. The lifting platform comprises an operating platform rotatably connected to a positioner body and a plurality of lifting supporting mechanisms for supporting the operating platform to always meet working requirements, wherein the working requirements are met when an included angle between the operating platform and a horizontal plane is not more than 5 degrees, the supporting mechanisms are hinged to the lower end of the operating platform, the plurality of supporting mechanisms are distributed on the two sides of the positioner body correspondingly, the supporting mechanisms ascend and descend along with ascending or descending of the positioner body, and when the positioner body ascends and descends, the operating platform rotates around a connecting point of the operating platform and the positioner body under the action of the supporting mechanisms to maintain the included angle between the operating platform and the horizontal plane not more than 5 degrees all the time. The lifting platform is arranged on the positioner, even if a length of a welding roller exceeds 1.2 m, an operator can also normally check a welding condition between a hub and a roller body, and the welding quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of circular elevation angle welding machines, and in particular relates to a lifting platform arranged on a positioner. Background technique [0002] The wheel hub is the part on both sides of the reversing drum. When the reversing drum is processed, the hub and the drum body need to be welded together. The welding of the wheel hub and the drum body is generally performed by a circular elevation welding machine. When welding to the drum, the reversing drum needs to be lifted up with the positioner matched with the circular elevation angle welding machine to form a 45-degree angle. After lifting, the weld between the hub to be welded and the cylinder body forms a V-shaped weld. This facilitates soldering. However, when the length of the welding drum exceeds 1.2 meters, the height of the welding seam of the hub and the cylinder exceeds the height of the normal line of sight of the operator, so that the operat...
