Description

Technical Field

[0001] This utility model relates to the field of headrest processing technology, specifically to a pressing device for processing automotive headrests. Background Technology

[0002] With the upgrading of my country's industries, the automotive industry has become a pillar industry in my country due to its high added value, high technology, and high demand. To enhance passenger comfort, headrests are installed above the seats to support the head and reduce fatigue. For safety, headrests are designed with internal clips, requiring a pressing device during installation to ensure the clips engage. However, during the pressing process, both hands must be pressed on the button. If the headrest is not properly positioned before pressing, it may shift, damaging internal components. Furthermore, when the headrest shifts, the support rod on its side also moves. If this rod reaches the contact point between the upper and lower modules, it can damage the pressing device. Utility Model Content

[0003] The purpose of this invention is to provide an automotive headrest processing and pressing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a car headrest processing and pressing device, comprising a housing, a hydraulic rod fixedly connected to the upper middle of the housing, a pressing block fixedly connected to the power output end of the hydraulic rod, a support base fixedly connected inside the housing, the support base being directly below the pressing block, a positioning cavity provided in the upper middle of the support base, a headrest placed in the positioning cavity, two fixing rods provided in the middle of the headrest, two positioning grooves provided on the side end of the pressing block, two positioning holes provided on the upper side of the support base, a connecting column fixedly connected in the positioning holes, a sliding cylinder inserted into the connecting column, a spring fixedly connected between the sliding cylinder and the connecting column, a positioning block fixedly connected to the upper end of the sliding cylinder, a placement groove provided at the upper end of the positioning block, a fixing groove provided at the lower end of the placement groove, an installation block inserted into the fixing groove, and a magnet fixedly connected to the upper end of the installation block.

[0005] Preferably, the placement groove has a V-shaped structure, the fixing rod is placed in the placement groove, the upper surface of the magnet block is an arc-shaped concave surface, both sides of the magnet block are inclined surfaces, and the fixing rod is magnetically attracted to the upper end of the magnet block.

[0006] Preferably, both sides of the mounting block are fixedly connected with snap-fit ​​protrusions, the snap-fit ​​protrusions are rubber protrusions, and both sides of the inner wall of the fixing groove are provided with snap-fit ​​grooves, and the snap-fit ​​protrusions snap into the snap-fit ​​grooves.

[0007] Preferably, the upper end of the positioning block is provided with guide arc surfaces on both sides, and when the pressing block is pressed down, the positioning block is engaged in the positioning groove.

[0008] Preferably, the left and right sides of the support base are arc-shaped concave surfaces, and the front and rear sides of the support base are arc-shaped convex surfaces.

[0009] Compared with the prior art, the beneficial effects of this utility model are: the headrest is placed in the positioning cavity for initial positioning, and at the same time, the fixing rod is placed on the placement groove of the positioning block. The magnet in the middle of the placement groove attracts the fixing rod, thereby positioning and fixing the fixing rod. Thus, the headrest is positioned and fixed before pressing, preventing the headrest and fixing rod from moving during pressing, ensuring the accuracy of pressing, and avoiding damage to parts and equipment due to displacement of the headrest.
