Description

General type welding robot intelligence tilting mechanism Technical Field The invention relates to the technical field of intelligent welding equipment, in particular to an intelligent turnover mechanism of a universal welding robot. Background With the development of industrial automation, welding robots are popularized and applied in the manufacturing and processing links of metal structural parts. For the workpieces with complex shapes and large volumes, the comprehensive welding operation cannot be completed at a single angle, and the matched turnover mechanism drives the workpieces to rotate and change the postures to match with the robot to complete the operation, so that the conventional selection is realized. The existing turnover mechanism generally adopts a fixed frame structure, and the operation is complicated and limited when loading and unloading large-sized workpieces. The split type opening and closing structure is adopted for part of the equipment, but the closing joint part of the upper and lower half frames lacks of accurate guiding and positioning structure, and the closing operation is easy to generate dislocation. Meanwhile, the locking device after closing mostly adopts a bolt bolting mode, and under the condition that a bearing workpiece is turned over and stressed, the connecting part is easy to loosen and generate relative displacement, so that the whole structure is unstable and the welding precision is influenced. The device for clamping and fixing the workpiece by the existing equipment has a single structure, and mostly adopts a plane direct-pushing clamping plate. In the face of the workpieces with cambered surface contours in different sizes, a single clamping plate cannot be completely attached to the outer surface of the workpiece, the contact area is small, and the stable limiting and supporting effects cannot be achieved. The manual repeated adjustment of different clamps is not only labor-consuming, but also uneven stress is easy to cause indentation and dent on the surface of the workpiece and damage local structures. The clamping assembly lacking coordinated adjustment is poorly adaptable when clamped against a non-standard workpiece body. In addition, when the movable base slides along the bottom side rail to adjust the processing position, welding waste residue particles and metal splashes scatter on the surface of the rail. Conventional guide rail structure does not be equipped with synchronous clearance lubricating arrangement, and the movable base rolls the waste residue and can form the mar and cause wearing and tearing at the track surface. The lack of a slag discharging and oil supplying smearing mechanism with linkage operation can not synchronously finish guide rail cleaning and micro lubrication during sliding movement, so that the service life of the rail is shortened, and the sliding running stability is affected. Disclosure of Invention Aiming at the defects of the prior art, the invention provides the intelligent turnover mechanism of the universal welding robot, which solves the problems that the existing turnover mechanism is inaccurate in closing and positioning and easy to loose when a workpiece is assembled and disassembled, a single clamping part cannot adapt to the workpiece with a complex outline to cause unstable fixation, and a base is lack of synchronous deslagging and lubrication mechanism to cause rail abrasion when moving. The intelligent turnover mechanism of the universal welding robot comprises a bottom plate and a workpiece body, wherein the top of the bottom plate is fixedly connected with a track, the outer sides of two ends of the track are both in sliding connection with a sliding rail bottom frame plate, a slag discharging micro-lubrication assembly is arranged in the sliding rail bottom frame plate, two ends of the sliding rail bottom frame plate are both fixedly connected with fixed support posts, the outer sides of the two fixed support posts are both provided with turnover opening and closing assemblies, and the end parts of the turnover opening and closing assemblies are provided with clamping assemblies so as to prevent displacement during operation; The overturning opening and closing assembly drives the clamping assembly and the limiting assembly to limit the position of the workpiece body; The overturning opening and closing assembly comprises two semicircular frame bodies, the two semicircular frame bodies are distributed according to an upper portion and a lower portion, the lower portion is fixedly connected with the outer side of the fixing support, the outer side of the end portion of each semicircular frame body is fixedly connected with an L-shaped plate, the upper portion is rotatably connected with the outer side of each L-shaped plate, the outer side of each L-shaped plate is rotatably connected with two first electric push rods, the end portions of the two first electric push rods are all arranged on the outer s
