Description

Self-edge-finding flexible attaching chamfering device Technical Field The invention relates to a self-edge-finding flexible bonding chamfering device, and belongs to the technical field of metal plate processing equipment. Background In the industrial fields of ship manufacturing, steel structure processing, pressure vessel manufacturing and the like, edge treatment of plates is a key process before welding. The high-quality chamfer not only can remove burrs and stress concentration generated by cutting, but also can form a specific chamfer shape, thereby obviously improving paint adhesion and welding quality. The main stream of the chamfering device for the plate adopts a processing mode of combination of linear feeding and fixed cutters, namely, the plate is conveyed along the linear direction by a conveying device, and the chamfering cutter fixed on one side cuts the side edge of the plate. Such devices are capable of meeting basic processing requirements when handling straight edges of regular rectangular sheet material, but their inherent drawbacks are particularly pronounced in the face of complex operating conditions. For the plate with arc-shaped outline and special-shaped edge, the fixed cutter can not adapt to the continuous change of the edge curvature, so that the joint degree of the cutter and the plate edge is poor, the problems of uneven chamfering width, missing chamfering and even damage to the plate surface occur, and the machining precision is difficult to guarantee. In order to finish the multilateral processing of the plate, manual overturning or repeated clamping is usually required, so that the production efficiency is low, and the labor intensity and the safety risk of operators are increased. For this situation, the patent of the patent CN216680551U discloses an automatic chamfering device, which adopts a mode that one side is fixed and the other side is floating and attached, and can realize chamfering molding of one group of opposite end faces, while chamfering of the other group of opposite end faces still needs turning operation, and is not applicable to round, elliptic and other plates. Currently, in order to meet the requirement of one-time clamping of the outer Zhou Daoleng, a chamfering machine capable of chamfering along the outline of the periphery of a plate is arranged, a main shaft walking path for chamfering can be generated according to the outline of the plate, and peripheral chamfering operation is carried out along the outline line. However, the peripheral outline of the plate is uneven, especially the top edge and the bottom edge of the periphery may have relative inclination, concave-convex, etc., so that the top edge outline and the bottom edge outline are difficult to be accurate, which results in difficult formation of accurate planning of the main shaft walking path, generally only the chamfer path conforming to the general outline of the plate is given, so that the edge uniformity of the traditional peripheral chamfer machining is poor, and the machining requirements of late welding, etc. of the plate cannot be met. In order to improve the situation, part of the existing equipment is introduced with a unidirectional floating compensation mechanism, so that unidirectional floating lamination of the chamfering main shaft can be realized, and the chamfering quality is improved to a certain extent. However, the mechanism can only adapt to small deviation in a single direction, when the multi-dimensional profile change or the large curvature arc line is processed, the condition of frequent steering control exists, and meanwhile, the milling conical surface of the cutter of the chamfering spindle is possibly inclined, so that stable attachment of the cutter and the edge of the plate cannot be realized, and the dynamic response is delayed, so that the fluctuation of the processing quality is easily caused. Disclosure of Invention The invention aims to solve the defects of the prior art, and provides a self-edge-seeking flexible bonding chamfering device, aiming at the problems that the traditional outer Zhou Daoleng has single floating direction, frequent steering control is needed, the processing quality and efficiency are influenced by dynamic response lag and the like. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: The self-edge-seeking flexible bonding chamfering device comprises a plate carrying platform for supporting and locking a plate to be processed and a displacement carrying seat arranged at the top of the plate carrying platform and provided with a displacement in a horizontal plane; the displacement carrier is provided with a follow-up leaning mechanism, and the follow-up leaning mechanism comprises a floating base, a floating carrier movably matched with the floating base and an elastic floating assembly connected with the floating base and the floating carrier; The floating base is provided with
