[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0033] Example:
[0034] like Figure 1 As shown, the embodiment of the present application discloses a tool for processing the outer circle of a long thin-walled sleeve, which is used to complete the processing of thin-walled parts with a large aspect ratio, specifically, it can be a thin-wall processing with an aspect ratio of 6, effectively avoiding the influence of the expansion point on the overall dimensional accuracy of the product;
[0035] The specific structure of the tooling in this application includes:
[0036] A tool body 1, wherein an assembly channel 101 is provided inside the tool body 1, and the specific style of the tool body 1 is similar to the thin-walled part to be processed, so that it can meet the requirements of the long diameter;
[0037] A locking bolt 2 is installed at one end of the tool body 1, and the locking bolt 2 is used to cooperate with the flange part of the thin-walled part;
[0038] A tension fitting 3 is arranged inside the assembly channel 101 and is located at the other end of the tool body 1. The tension fitting 3 is used for subsequent installation of an expansion ring to ensure the dimensional stability of the end portion;
[0039] The expansion ring 4 is installed at the other end of the tension fitting 3 away from the tooling body 1. The expansion ring 4 cooperates with the tension fitting 3. Because the length-diameter ratio is relatively large, the size of the end portion is prone to change, which affects the accuracy of the processed product. The expansion ring 4 can avoid the size change;
[0040] The push plate 5 is installed on the outer side of the expansion ring 4, and is used to push the expansion ring 4 to move, so as to achieve stability of the expansion ring after assembly.
[0041] The structure of the tool body 1 is described as follows: the tool body 1 is an integrally formed part, and the tool body 1 includes:
[0042] A support section 102, on which the locking bolt 2 is installed; the support section 102 is specifically matched with the flange section of the thin-walled part to be processed, and is locked by the locking bolt 2, so as to ensure the stability of subsequent processing;
[0043] The tensioning section 103 is arranged on one side of the supporting section 102, and an assembly channel 104 is opened inside the tensioning section 103, and the tensioning section 103 is perpendicular to the supporting section 102; in the present application, the tensioning section 103 extends into the interior of the product to be processed. Due to the length of the product to be processed, in order to avoid the length being too long and the subsequent dimensional changes, a tension fitting is installed at the end of the tensioning section 103 to ensure stability.
[0044] The outer circles of the tension fitting 3 , the outer circles of the expansion ring 4 and the outer circles of the tensioning section 103 are in the same plane, so that the accuracy of the processed product can be ensured.
[0045] Specifically, the tension fitting 3 is interference-fitted with the assembly channel 101 , which can ensure the stability of the entire tooling during processing.
[0046] Wherein, a raised section 301 is provided on the outer side of the tension fitting 3;
[0047] The side of the expansion ring 4 is provided with a groove section 302 that matches the protrusion section 301 . The groove section 302 and the protrusion section 301 cooperate with each other so that the expansion ring 4 can be stably assembled and can subsequently stably support the inner wall of the workpiece to be processed.
[0048] The outer side surface of the raised section 301 is an inclined surface, and the width of the raised section 301 gradually increases from the connecting end to the free end, so that the stability of the raised section 301 can be ensured.
[0049] In the specification of the present utility model, a lot of specific details are described. However, it is understood that the embodiments of the present utility model can be practiced without these specific details.
