[0032] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0033] See also Figure 2-5 The present invention discloses a flexible press-fitting tool. As shown in the figure: it includes:

[0034] The tooling bracket 1 is composed of an upper base 11, a vertical plate 12 and a lower base 13, and the upper base 11 and the lower base 13 are respectively connected to the two ends of the vertical plate 12.

[0035] The upper tooling module 2 is used to fix one end of the distribution pipe assembly and is arranged on the upper base 11.

[0036] The lower tooling module 3 for fixing the other end of the distribution pipe assembly is arranged on the lower base 13 .

[0037] A plurality of coaxially arranged distribution pipe positioning V-shaped blocks 4 are arranged on the vertical plate 12 and located at the upper tooling module 2 and the lower tooling module 3 for placing and positioning the distribution pipe assembly.

[0038] A distribution pipe pressing cylinder 5 for pressing the distribution pipe assembly is arranged on the vertical plate 12.

[0039] The vertical plate 12 is provided with a slide groove 121, and the support plate clamping cylinder 6 is installed on the vertical plate 12 and can slide in the upper limit position of the slide groove 121. Therefore, the position of the support plate clamping cylinder 6 of the flexible pressing tool can be adjusted along the slide groove 121.

[0040] A support plate positioning block 7 for positioning the press-fitted support plate is also provided. The support plate positioning block 7 is designed with a wide surface and can be suitable for positioning support plates of different products.

[0041] like Figure 3 As shown, an end cap positioning block 21 is provided at the lower end of the upper tooling module 2, and its function is to press-fit the end cap component at one end while fixing one end of the distribution pipe assembly.

[0042] In the present invention, the vertical plate 12 is made of ferromagnetic material, and a magnetically movable photoelectric induction detector 8 is provided on the vertical plate 12. The magnetically movable photoelectric induction detector 8 can move freely on the vertical plate 12, and a specific error prevention method is adopted for different products.

[0043] Please combine Figure 1 See also Figure 4 , 5 The upper tooling module 2 is located above the upper base 11, and a spring 22 is arranged on the outer surface of the telescopic rod 20. The upper end of the telescopic rod 20 is a top block 23. A combined limit block is arranged between the top block 23 and the upper end surface of the upper base 11. The combined limit block is composed of a first limit block 91 and a second limit block 92 of a semicircular ring type. The first limit block 91 and the second limit block 92 can be spliced ​​together to form a full ring through a snap-fitting combination. This snap-fit ​​combination method can realize the rapid assembly and disassembly of the combined limit block. After the combined limit block is assembled, it is installed in a limit groove 111 provided on the upper end surface of the upper base 11. In order to adapt to different models of products, the height of the combined limit block can be set to multiple specifications as needed, and the combination method remains unchanged, and it is also installed in the limit groove 111. In addition, an observation hole 93 can be set on the combined limit block to observe the working condition of the internal spring 22 at any time.

[0044] In the present invention, the lower tooling module 3 includes an end cap press-fitting structure or an oil inlet pipe assembly press-fitting structure, and the end cap or the oil inlet pipe assembly can be press-fitted on the other end of the distribution pipe assembly as needed.

[0045] In order to assist installation, a first auxiliary block 31 and a second auxiliary block 32 are disposed near the lower tooling module 3 , and the first auxiliary block 31 and the second auxiliary block 32 are installed on the lower base 13 .

[0046] The present invention also discloses a bracket plate press-fitting method through a flexible press-fitting tool, such as Figure 6 As shown, the steps are:

[0047] A places the distribution pipe assembly A on the coaxially arranged distribution pipe positioning V-shaped block 4, and its two ends are respectively pressed by the upper tooling module 2 and the lower tooling module 3, and further positioned and pressed by the distribution pipe pressing cylinder 5.

[0048] B sets the support plate to be pressed on the support plate positioning block 7, slides the support plate pressing cylinder 6 to the pressing position through the slide groove 121 and presses the support plate.

[0049] The above step B can reflect that the biggest difference between the tooling of the present invention and the special tooling in the background technology is that the bracket plate pressing cylinder 6 is slid to the pressing position and presses the bracket plate through the slide groove 121, which can adapt to the needs of pressing different specifications of products for changes in the pressing position, and there is no need to set up another set of tooling.

[0050] In addition, according to the change of the length or diameter specification of the distribution pipe assembly A itself, the specification change can be coped with by replacing the combined limit block designed by the tooling of the present invention, thereby further expanding the application scope of the tooling.

[0051] In step A, the end cap is press-fitted onto one end of the distribution pipe assembly A by the upper tooling module 2 .

[0052] In step A, the end cover or the oil inlet pipe assembly is pressed onto the other end of the distribution pipe assembly A through the lower tooling module 3. That is to say, the press-fitting of the other end of the distribution pipe assembly can be replaced by various types such as end cover press-fitting and oil inlet pipe press-fitting through the lower tooling module 3.

[0053] It can be seen that the flexible pressing tooling of the present invention comprises multiple groups of standardized modules (replaceable combined limit blocks, movable bracket plate clamping cylinders, magnetic movable photoelectric sensing detectors, etc.); the standardized modules of the flexible pressing tooling can be used for quick disassembly and replacement; the flexible pressing tooling can cover the pressing operations of products of various specifications.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. That is, any equivalent changes and modifications made according to the content of the patent application scope of the present invention should be within the technical scope of the present invention.
