Description

Technical Field

[0001] The utility model relates to the technical field of press-fitting, and more specifically, to an automatic press-fitting machine. Background Art

[0002] In the powder metallurgy processing industry, it is often necessary to press two parts together to form a complete component. A press is a mechanical device used to press two or more parts together to form an integral component. It applies a certain amount of pressure to create a tight connection or fit between the parts.

[0003] After searching, a Chinese patent with announcement number CN220660724U discloses a press machine. In view of the existing technology, the workpiece is generally fixed on the positioning mechanism of the press machine. The positioning mechanism provides a certain position and angle, and cooperates with the pressure head mechanism to apply pressure to the part to be pressed (i.e., bearing, bushing or gear) to press the part to be pressed to the pressing part of the workpiece. In the above process, the positioning mechanism is stationary relative to the pressing part, and the pressing is achieved only by the action of the pressure head mechanism, which has a low efficiency. The workpiece is placed on a support, the pressing part of the workpiece is placed between the pressure head and the positioning member, and the part to be pressed is placed on the pressure head. The pressure head and the positioning member are respectively located on opposite sides of the pressing part of the workpiece on the support; during operation, the pressure head and the positioning member are moved relative to each other by the driving mechanism to press the part to be pressed into the pressing part of the workpiece; under the action of the driving mechanism, the pressure head and the positioning member simultaneously apply force to both ends of the pressing part of the workpiece, thereby improving the pressing efficiency.

[0004] During the use of this press, for two parts that need to be pressed, the chamfering process is often carried out separately. Each part needs to be chamfered in different equipment or processes, and then transferred to the pressing process. This step-by-step operation method is not only cumbersome, but also prone to bumps and damage during the transfer of parts. Utility Model Content

[0015] The technical effects and advantages of this utility model are:

[0016] 1. By setting up a moving mechanism and a pressing mechanism, and by making the two parts to be pressed be chamfered after being transported by two first conveyor belts respectively, the two parts can be automatically chamfered and pressed at the same time, avoiding the intermediate links in the step-by-step operation, greatly shortening the production cycle, significantly improving production efficiency, and realizing a fully automated process of part transmission, clamping, movement, chamfering and pressing, avoiding collision of parts during the transfer process, reducing the time and labor intensity of manual operation, and greatly improving production efficiency;

[0017] 2. By automatically conveying parts and automatically performing chamfering and press-fitting, operators do not need to directly participate in the press-fitting process of parts, which improves the protection effect and reduces the probability of work-related accidents. At the same time, after two parts are press-fitted to form an assembly, the electric push rod drives the second movable push plate to move, so that the second movable push plate pushes the press-fitted assembly into the second conveyor belt, making it easier to transfer the assembly to the next processing flow through the second conveyor belt, thereby improving the overall processing efficiency of parts.
