Description

Technical Field

[0001] This utility model belongs to the field of pressing equipment technology, and specifically relates to a pressing tool for automotive switches. Background Technology

[0002] An automotive switch consists of two parts: a housing and a button body. The two parts must be pressed together to form a complete switch.

[0003] Existing pressing equipment often suffers from incomplete pressing on a single attempt, requiring operators to press the switch button multiple times to achieve the desired pressing effect. This is time-consuming, labor-intensive, and inefficient, and also presents the problem of inconsistent assembly quality due to manual counting errors. To address this issue, utility model application CN202320975076.0 discloses a "continuous and precise pressing device for plastic products." This utility model includes a base, a support column, a pressing switch box, and an electrical control box fixed above the base. A mounting plate is fixed to the upper part of the support column, and a cylinder is fixed above the mounting plate. An upper pressure plate is connected to the telescopic end of the cylinder, and a lower pressure plate is located on the upper part of the base corresponding to the upper pressure plate. This utility model controls the cylinder to achieve the pressing process of the workpiece by adding an electrical control box with a PLC controller. The number of pressing cycles can be preset by the PLC to automatically execute multiple continuous pressing operations with a single start. However, the main function of this utility model is to reduce labor intensity, and it is suitable for products requiring large pressing forces. Furthermore, its structure is relatively complex, and the tooling cost is high.

[0004] Utility model application CN202022154592.6 discloses a "thermomeling machine for producing plastic parts". This utility model includes a mounting base plate, a drive mechanism, and a pressing mechanism. The pressing mechanism is connected to the drive mechanism via a T-shaped rack. In operation, the utility model uses a motor to drive a first gear to rotate, which in turn drives a second gear to rotate. Simultaneously, the rotation of the second gear causes the T-shaped rack to change position, thereby pushing the pressing device up and down to achieve the thermomelting process for plastic parts. However, the structure of this utility model is overly complex. Utility Model Content
