Each pin is inserted into a corresponding connection hole and the pins are bent. The brushed panel is fixedly assembled to the upper shell by the bent pins.

[0003] In the existing technology, the assembly of such shells that require pin bending can only be done manually with the help of tools such as pliers, which has the disadvantages of poor assembly efficiency and high damage rate. In addition, since the brushed panel is not supported and fixed when the pins are bent, and the brushed panel is not in close contact with the surface of the upper shell, it is easy to cause the brushed panel to loosen.

[0021] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0022] like Figure 5 This utility model aims to solve the problem of automatic pressing and assembly of a thin vacuum machine housing 91. The vacuum machine housing 91 has a pressing and mounting position formed on each side. The edge of the pressing and mounting position has a through mounting hole 911. The bottom of the vacuum machine housing 91 has a bolt leg 90. The pressing and mounting positions on both sides need to be fitted with a brushed panel 92. The front side of the brushed panel 92 has a curved part, and the bottom of the brushed panel 92 has multiple pin units 921. During installation, the brushed panel 92 needs to be attached to the corresponding pressing and mounting position. At the same time, each pin unit 921 is inserted into the corresponding mounting hole 911. Then, each pin unit 921 is bent so that it is upside down on the inner side of the vacuum machine housing 91 to complete the assembly.

[0023] In the existing technology, the assembly and processing between the brushed panel 92 and the vacuum machine housing 91 can only be completed manually, which is very cumbersome and prone to loose assembly of the brushed panel 92 due to incomplete adhesion.

[0024] The inventors have proposed an automatic pressing device for thin-walled components, which automatically bends the pins during pressing, eliminating the need for manual assembly and improving assembly efficiency and quality.

The pallet 3 is fixed to the table surface of the machine platform 11. The upper surface of the pallet 3 has a contoured tooling positioning structure for positioning the housing workpiece to be assembled. The tooling positioning structure includes a limiting concave surface that matches the bottom surface of the workpiece. The bottom surface of the limiting concave surface has multiple positioning holes 30. Through holes extend to the limiting concave surface.

The pressing drive device is driven and connected to the pressure plate 22 and to a control device. The contoured pressing member 221 includes an EVA profile, which is bonded to the bottom surface of the pressure plate 22. The EVA profile has a Shore hardness of 65. This prevents damage to the vacuum machine housing 91 and the brushed panel 92.

[0026] The processing steps of this pressing and assembly equipment are as follows: First, the vacuum machine housing 91 is placed on the tooling positioning structure of the tray 3, and its bolt joints 90 are respectively inserted into the corresponding positioning holes 30 to achieve positioning; then, the two wire drawing panels 92 are respectively placed in the corresponding pressing and installation positions according to the set body position, and the pin units 921 are respectively inserted into the corresponding assembly holes 911; the equipment is started, and the pressure plate 22 moves downward, driving the contour pressing parts 221 to press against the surface of the wire drawing panel 92 respectively, and the bottom end of the pin unit 921 abuts against the oblique angle 341 of the bending top rod 34 to complete the automatic bending.

[0027] In this embodiment, the pressing part composed of two or more contoured pressing parts can accurately press the brushed panel 92 of the vacuum machine housing 91, ensuring that the assembly fit between the brushed panel 92 and the vacuum machine housing 91 meets the production requirements, further improving the assembly quality of the brushed panel 92 and reducing the defect rate.

[0028] The brushed panels 92 on both sides can automatically press and bend the pins in the same pressing cycle, which greatly improves the assembly efficiency and ensures that the bottom surface of the brushed panel 92 is in close contact with the vacuum machine housing 91, thus ensuring the assembly quality and reducing the defect rate.
