Description

Split type rotary positioning device of door package mould Technical Field The utility model relates to the technical field of dies, in particular to a split type rotary positioning device for a vehicle door packaging die. Background In the whole automobile remanufacturing process, the assembly positioning link of the outer plate and the inner plate assembly of the automobile door is important. In particular to the field of remanufacturing of vehicle doors, the realization of accurate inclusion positioning of an outer plate and an inner plate assembly of the vehicle door is a core key point for ensuring the quality of the vehicle door assembly. Thus, the positioning accuracy of the inclusion mold in door remanufacturing is critical, which directly affects the quality of the door assembly. At present, most of tool positioning mechanisms matched with the car door packaging die in the market adopt integrated special-shaped compacting blocks, the integrated special-shaped compacting blocks are designed and completed in advance according to the shape of the car door inner plate, but because the special shape or a certain curved surface exists, the integrated special-shaped compacting blocks are required to be completed through complex numerical control machining, the process flow is long, the machining cost is high, the inclination angle of the machined integrated special-shaped compacting blocks is fixed and dead, the integrated special-shaped compacting blocks are possibly influenced by the installation error caused by fixing the integrated special-shaped compacting blocks in the packaging die process by operators, the situation that the curved surface of the car door inner plate cannot be completely attached to the integrated special-shaped compacting blocks is generated, the special-shaped compacting blocks cannot be attached to the car door inner plate again after one-time machining is completed, the special-shaped compacting blocks are unstable in compacting effect, deviation gaps are easily generated, the adaptability is poor, the special-shaped compacting blocks can be redesigned, the machining cost is additionally increased, time and labor are wasted, and finally the effect achieved is poor, and the requirements of the current car remanufacturing industry on high-efficiency and high-quality production process are difficult to be met. In view of the above-mentioned shortcomings in the prior art, there is a need to optimize and improve the positioning mechanism of the assembly die for remanufacturing a door of an automobile, so as to improve the overall quality and efficiency of remanufacturing the automobile. Disclosure of utility model The utility model provides a split type rotary positioning device of a vehicle door wrapping die, which has the advantages of simple structure, simple and convenient manufacture, easy realization and low cost, and solves the problems of long process flow, high processing cost and poor adaptability caused by the adoption of an integrated special-shaped compression block in the existing tool positioning mechanism, and mainly adopts the following technical scheme: The split type rotary positioning device for the vehicle door packaging die is characterized by comprising a locking and pasting mechanism and a turnover mechanism, wherein the locking and pasting mechanism comprises a special-shaped base and a transition block, the special-shaped base is at least provided with one side plane welded with the transition block, the other end of the special-shaped base is provided with a connecting part and is used for being fixed with a vehicle door inner plate through a fastening structure, the transition block and the side plane of the special-shaped base are welded to form a preset angle, the turnover mechanism comprises a rotating arm and a mounting block fixedly arranged on the packaging die, one end of the rotating arm is welded and fixed with the transition block, the other end of the rotating arm is hinged with the mounting block through shaft pin fit, and the special-shaped base and the vehicle door inner plate can be mutually and closely contacted when the rotating arm swings outwards to reset through rotation. Preferably, the turnover mechanism further comprises a shaft pin, and the shaft pin is arranged in the shaft hole of the rotating arm and the hinge hole of the mounting block in a penetrating manner, so that the rotating arm and the mounting block form hinge connection to rotate around the shaft pin. Preferably, the installation block is a concave steel block, the front surface of the installation block is provided with a fixing hole for being matched and locked with the inclusion mould, and the side surface of the installation block is provided with the hinge hole. Preferably, the predetermined angle is 30 ° to 60 °. Preferably, the special-shaped base is formed by cutting a round bar on one side to form the side plane so as to form a D-shaped structure.
