Description

Efficient butt welding device for rim production Technical Field The invention relates to the field of rim welding and positioning, in particular to a high-efficiency butt welding device for rim production. Background The rim is a core bearing component of a vehicle running system, and is formed by combining a spoke and a rim, namely, the circumferential seam butt welding of the spoke and the rim is a key process for rim production, and the welding quality directly determines the structural strength, the running stability and the use safety of the rim. At present, an operation mode of horizontal clamping is commonly adopted in the inner rim butt welding operation in the industry, after workpiece feeding, independent limiting is carried out on spokes and rims respectively through multiple groups of independent positioning auxiliary tools, coaxiality calibration of the spokes and the rims is realized through manual repeated adjustment, the clamping process is complex, the front preparation time of a single workpiece is long, and the beat requirement of large-batch continuous production is difficult to adapt. Meanwhile, the workpiece is free from natural guiding limit in the horizontal clamping mode, clamping deviation is easy to occur, coaxiality deviation after welding exceeds standard, and finished product reject ratio is high. The clamping mechanism of the existing butt welding device mostly adopts a radial rigid clamping operation mode, a clamping piece directly applies larger radial clamping force to the outer wall of the rim to fix a workpiece, the rim is a thin-wall annular member, the deformation resistance of the rim is weaker, the rigid clamping is extremely easy to cause the out-of-roundness of the rim caused by plastic deformation, and the assembly precision of the subsequent tire and the service life of a finished product are further influenced. In addition, the existing clamping mechanism can only realize radial limiting of a workpiece, cannot apply uniform axial pretightening force to a welding joint surface of a rim and a spoke, and is easy to cause gaps on the joint surface due to welding thermal deformation in the welding process, so that the defects of weld joint cold joint, penetration welding, incomplete penetration welding and the like are caused, the welding structural strength of the rim is further weakened, and the structural stability of a rim welding part is affected. Although few schemes try to adopt an oblique clamping mode to simplify the positioning process, the existing oblique clamping scheme cannot solve the core problem that workpieces are easily affected by welding vibration and thermal deformation when being obliquely distributed and slip dislocation occurs, a complex displacement preventing mechanism is additionally arranged, and the structural complexity, equipment cost and later maintenance difficulty of the device are greatly increased. Meanwhile, the prior art always fails to realize the cooperative adaptation of clamping positioning and clamping shape retention, clamping efficiency and welding precision are in contradictory states for a long time, and core production requirements of high efficiency, high precision and low deformation of rim butt welding operation cannot be met at the same time, so that the efficient butt welding device for rim production is necessary to design. Disclosure of Invention Based on the above, it is necessary to provide an efficient butt welding device for rim production, which solves the problems of the prior art. In order to solve the problems in the prior art, the invention adopts the following technical scheme: the utility model provides a rim production is with high-efficient butt welding device, includes the welding bench, still includes: the welding device comprises a slope frame obliquely arranged at the upper end of a welding table, an annular disc is fixedly connected to the upper end of the slope frame, two supporting plates for bearing the bottoms of spokes are symmetrically arranged in the middle of the annular disc, the two supporting plates incline to one side close to the circle center of the annular disc, a cam block fixedly connected with the slope frame is arranged at the circle center of the annular disc, and the spokes in the welding process are hung on the upper side of the cam block; The device comprises a ring-shaped disc, a slope frame, a ring-shaped disc, a support plate, a transverse clamping mechanism and a non-rigid clamping mechanism, wherein one end of the ring-shaped disc, which is close to the slope bottom of the slope frame, is provided with two arc-shaped frames for bearing the outer wall of the rim; the upper ends of the two auxiliary pushing plates are respectively provided with auxiliary pressing blocks in a sliding manner, and after the auxiliary pushing plates move towards the direction close to the annular disc, the auxiliary pushing plates are propped against the rim opening of the rim from the dir
