Description

Technical Field

[0001] This utility model relates to the field of component assembly technology, and in particular to a pin assembly fixture for plastic parts. Background Technology

[0002] The conventional structure of plastic components for automotive USB charging panels consists of a base with an openable and closable cover connected by tiny pins. Current production methods rely on manual assembly of these pins. Workers must not only hold the tiny pins by hand or use clamps to hold them, align them with the pin holes, and install them, but also push the pins in place. This assembly process is time-consuming, labor-intensive, and inefficient. Large-scale assembly of USB charging panels requires multiple workers to maintain production schedules, increasing costs. Especially under prolonged work pressure, the pins are prone to misalignment, affecting assembly accuracy. Therefore, it is necessary to design an efficient assembly fixture for assembling the pins of automotive USB charging panel plastic components. Summary of the Invention

[0003] The purpose of this utility model is to provide a pin assembly fixture for plastic parts. This pin assembly fixture for plastic parts has a reasonable design and simple structure, which improves the pin assembly efficiency and ensures the assembly accuracy.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A fixture for assembling plastic parts with a shaft pin includes a base; the base is provided with a product fixing seat, a shaft pin placement seat, and two symmetrically arranged displacement driving devices; the shaft pin placement seat is located between the two symmetrically arranged displacement driving devices; the product fixing seat and the shaft pin placement seat are arranged opposite to each other; the shaft pin placement seat is provided with a positioning groove and a through hole; the displacement driving devices are provided with ejector pins; the positioning groove, through hole, and ejector pin are arranged opposite to each other.

[0006] In this invention, the product fixing seat is used to fix the product and is a conventional technology designed according to the product to be assembled; the pin placement seat is used to place the pin; the positioning groove is used to place the pin to be assembled; and the displacement driving device is used to drive the ejector pin to move. The through hole penetrates the pin placement seat, and the positioning groove, through hole, and ejector pin are arranged opposite to each other, meaning that the ejector pin can pass through the through hole to push the pin placed on the positioning groove into the pin hole of the product.

[0007] Preferably, a product fixing head is provided above the base; the product fixing head is located on the outside of the product fixing seat. The product fixing head is used to press the product down to prevent the product from shifting during the assembly of the shaft pin, which would affect the assembly.

[0008] Preferably, the lower surface of the product fixing head is provided with a flexible pad. More preferably, the flexible pad is a rubber pad or a silicone pad, which can be selected as needed in actual application to prevent the product fixing head from scratching the product.

[0009] Preferably, the product fixing pressure head is mounted on the base via a rotary pressing drive device. The rotary pressing drive device is used to drive the product fixing pressure head to press the product.

[0010] Preferably, a transparent baffle is provided above the base. The transparent baffle is located above the pin holder and serves to protect the operator from injury caused by improper fit between the pin and the pin hole, which could result in the pin breaking off and injuring the operator. In practical applications, the material of the transparent baffle can be selected according to needs, ensuring it does not interfere with the operator's work while providing a certain level of protection.

[0011] Furthermore, the transparent baffle is positioned above the base via a support column. More preferably, one end of the transparent baffle is movably connected to the support column via a hinge structure. Even more preferably, one end of the transparent baffle is movably connected to the support column via a hinge. The support column is used for installing the transparent baffle. In practical applications, one end of the transparent baffle is movably connected to the support column via a hinge structure, while the other end rests directly on the support column. When fixing the product to be assembled, the transparent baffle can be opened for easy operation.

[0012] Furthermore, a hand lever valve is provided on the base. The hand lever valve is a conventional product used to control the movement of displacement drive equipment and rotary pressure drive equipment. The specific connection method and usage method are conventional technologies and do not affect the understanding of this utility model by those skilled in the art.

[0013] Preferably, the lower surface of the base is provided with support legs.

[0014] Furthermore, the symmetrically arranged displacement driving devices are located at both ends of the base along its length.

[0015] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: First, by cooperating with the product fixing seat and the shaft pin placement seat, the product to be assembled is fixed in the product fixing seat. The displacement driving device drives the ejector pin to push the shaft pin into the pin hole of the product, thus completing the assembly work. This solves the problem of difficult shaft pin clamping when manually assembling small shaft pins in the prior art. In particular, it eliminates the need for manual alignment of the pin hole and the ejector pin, improving assembly efficiency and ensuring assembly accuracy. Second, by setting a product fixing pressure head, the product can be prevented from shifting during the assembly of the shaft pin, further ensuring the assembly work. At the same time, by setting a transparent baffle, the operator is protected from the situation where the shaft pin breaks out and injures the operator. Attached Figure Description
