DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] The compressor gasket assembly fixture is a device for riveting the gasket to the compressor bracket limit plate sheet metal. The existing riveting method is generally to install the sheet metal into the bracket and then rivet it through the upper pressure head. However, since gaskets need to be installed on both ends of the sheet metal, one end of the sheet metal needs to be turned over for a second riveting after riveting, which is inefficient.

[0023] In view of the above technical problems, the present application provides a compressor gasket assembly fixture. Figure 1 The overall structural schematic diagram of the compressor gasket assembly fixture is shown; Figure 2 A schematic structural diagram of the lower stamping part 400 is shown; Figure 1 and Figure 2 The compressor gasket assembly fixture is used to process the sheet metal part 000, including a lower template 100, a first hydraulic telescopic column 300 and an upper template 200 connected in sequence along a vertical plane, and an upper pressure head 210 is connected to the lower end surface of the upper template 200; and also includes a lower punch 400 arranged on the upper end surface of the lower template 100, and the lower punch 400 includes:

[0024] The second hydraulic telescopic column 410 is installed on the upper end surface of the lower template 100;

[0025] The lower ram 420 is connected to the output end of the second hydraulic telescopic column 410, and the lower ram 420 and the upper ram 210 are in the same vertical plane;

[0026] The lower punch 420 rises and penetrates the sheet metal part 000 when the upper punch 210 presses down the sheet metal part 000 .

[0027] During use, the rivet, the lower gasket, the sheet metal 000 and the upper gasket are placed above the second hydraulic telescopic column 410 in sequence. At this time, the first hydraulic telescopic column 300 is driven, and the first hydraulic telescopic column 300 drives the upper pressure head 210 to press down, and the second hydraulic telescopic column 410 is started at the same time. The lower head 420 is driven by the output end of the second hydraulic telescopic column 410 to rise and penetrate the sheet metal 000, so as to simultaneously perform riveting on the two end faces of the sheet metal 000. In the present application, through the arrangement of the second hydraulic telescopic column 410 and the lower head 420, the upper riveting can be performed while the lower riveting can be performed, so that the two end faces of the sheet metal 000 can be riveted at one time, thereby reducing the operation steps and improving the riveting efficiency.

[0028] It should be noted that the number of the lower punch 400 and the upper punch 210 matches the number of the riveting points on the sheet metal part 000. Figure 1 As shown, in the present application, the sheet metal part 000 has three riveting points, so the number of the upper punch 210 and the lower punch 400 is also set to three, but in some other embodiments, the number of the upper punch 210 and the lower punch 400 is not limited.

[0029] See also Figure 2 A support plate 430 is installed on the second hydraulic telescopic column 410 , the lower head 420 penetrates the support plate 430 , and a positioning groove 431 is formed on the upper end surface of the support plate 430 .

[0030] During use, the support plate 430 can be used to support the sheet metal 000 to provide support for the sheet metal 000, and the positioning groove 431 can be designed to match the protrusion on the end face of the sheet metal 000 to form a limit for the sheet metal 000, thereby preventing the sheet metal 000 from shifting during the riveting process and ensuring the accuracy of the riveting.

[0031] Continue to see Figure 2 A lifting member 440 is provided on one side of the second hydraulic telescopic column 410, and the lifting member 440 includes:

[0032] A spring 442, one end of the spring 442 is connected to the lower end surface of the support plate 430;

[0033] The push rod 443 passes through the support plate 430 , and the other end of the spring 442 is connected to the spring 442 . The push rod 443 and the sheet metal part 000 overlap on the projection surface of the support plate 430 .

[0034] During use, when the sheet metal 000 is riveted, the push rod 443 is squeezed downward by the sheet metal 000, and the spring 442 is stretched and deformed. When the riveting is completed, the upper pressure head 210 moves upward, and the spring 442 can drive the push rod 443 to move upward to lift the sheet metal 000 to form a demolding. Through the design of the push rod 443, it can automatically rise after the riveting is completed, thereby lifting the sheet metal 000 and ensuring the convenience of demolding the sheet metal 000.

[0035] Continue to see Figure 2 The lifting member 440 further includes a limiting cylinder 441, which is connected to the upper end surface of the lower template 100, and a push rod 443 is inserted into the limiting cylinder 441 and slidably connected thereto.

[0036] During use, the push rod 443 can move up and down in the limiting cylinder 441, and the limiting cylinder 441 is used to limit the sliding trajectory of the push rod 443 to prevent the push rod 443 from tilting and deflecting.

[0037] Continue to see Figure 2 An extended edge 444 is connected to the top of the top rod 443 , and the extended edge 444 covers the top rod 443 on the projection surface of the support plate 430 .

[0038] During use, the design of the extended edge 444 can match the notch of the sheet metal part 000, ensuring that the top rod 443 is in contact with the sheet metal part 000 under normal conditions, completing the extension of the top rod 443, and at the same time increasing the contact area with the sheet metal part 000 to ensure the support effect for the sheet metal part 000.

[0039] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
