Description

Positioning device for producing automobile air conditioner pipeline connecting pressing plate and working method thereof Technical Field The invention belongs to the technical field of machine tools, and particularly relates to a positioning device for producing a connecting pressing plate of an automobile air conditioner pipeline and a working method thereof. Background In the production assembly process of modern automobile air conditioner pipelines, the connecting pressing plate is used as a key connecting part, and cannot be effectively fixed through a traditional standardized positioning tool due to the irregular appearance structure of the connecting pressing plate. For this purpose, the conventional solution is to machine a positioning groove on the table surface, which is highly matched to the external dimensions of the connecting press plate. The groove can ensure that the pressing plate is accurately limited in position in the assembly (such as automatic screw locking) process, so that the assembly precision is ensured. However, the insertion of the connecting pressure plate into the recess, while ensuring assembly accuracy, presents a significant technical challenge in how to efficiently and nondestructively remove the connecting pressure plate from the mating recess. In the prior art, a jacking cylinder is generally integrated on the inner bottom wall of the groove, and the connecting pressing plate is ejected upwards through linear motion of a cylinder piston rod. Although this approach achieves a degree of automated removal, it suffers from a number of inevitable technical drawbacks in engineering applications, mainly reflected by: 1. The jacking cylinder acts rapidly and rigidly, and the piston rod of the jacking cylinder can apply an instantaneous impact force in the jacking process. Such impact forces are extremely likely to cause the mating, closely coupled platens to "pop" out of the grooves rather than "smooth ejection". The ejecting action has unpredictability, so that potential safety hazards can be caused to operators, and the pressing plate can collide with a workbench or other equipment when falling down, so that the finished outer wall or the finished inner structure of the pressing plate can be directly damaged, and the final quality of a product can be influenced. 2. The connecting platen is a precision part whose outer wall finish and dimensional integrity are critical. The cylinder piston rod is usually in point contact or small-area contact with the bottom of the pressing plate, and the pressure is concentrated. In the jacking process, if the pressing plate is slightly deflected, the edge of the piston rod is very easy to scratch or indentation the non-stress reinforcing area at the bottom of the pressing plate. In addition, post-pop-up impact is one of the main causes of workpiece damage. Therefore, how to efficiently and nondestructively remove the connecting pressing plate from the tightly matched groove is a technical problem in the art. It should be noted that the above information disclosed in this background section is only for understanding the background of the inventive concept and therefore the above description is not to be construed as constituting information of the related art.
