Description

Technical Field

[0001] The utility model relates to the relevant field of precision parts processing, in particular to an internal support tooling for high-precision thin-walled parts. Background Art

[0002] The machining process of thin-walled parts is full of multiple challenges due to their unique structural characteristics. These parts, with their fine wall thickness and fragile rigidity, are extremely susceptible to cutting forces and thermal deformation during machining, causing deformation. This deformation not only causes the geometric dimensions of the parts to deviate seriously from the design requirements, but in some cases, it may also cause irreversible damage to the overall structure and functional performance of the parts.

[0003] At the same time, there is the problem of clamping thin-walled parts. Due to their thin wall thickness and complex structure, traditional clamping methods often fail to provide sufficient support and stability, which can easily cause parts to shift or vibrate during processing. This instability will not only reduce processing accuracy, but may also cause additional wear and damage to machine tools and cutting tools. Therefore, we urgently need an internal support tooling designed specifically for thin-walled parts. This tooling should have excellent adaptability and stability, be able to fit tightly to the inner wall of the part, provide uniform and stable support, and ensure that the part maintains a stable position and posture during processing.

[0004] In order to effectively deal with this serious problem, we urgently need to introduce an internal support tooling with high stability. Utility Model Content

A lifting column is arranged above the base, and the lifting column is sequentially sleeved with the positioning guide, the threaded control part, the lower support part and the upper support part from bottom to top. A plurality of internal support sheets are arranged between the lower support part and the upper support part, and the plurality of internal support sheets are connected to the lifting column by screws, and a spring is arranged between the screws and the internal support sheets.

[0007] Furthermore, a lifting thread is provided in the middle of the lifting column, and a vertical sliding groove is provided on one side of the lifting column.

[0008] Furthermore, the lower end of the positioning guide is connected to the base, and a positioning pin is provided on the positioning guide, and the positioning pin is slidably connected to the lifting column through a vertical sliding groove.

[0011] Furthermore, an upper supporting truncated table is provided at the lower part of the upper supporting member, and the upper supporting member is fixedly connected to the lifting column.

[0012] Furthermore, three of the plurality of inner support plates are provided, and the inner support plates are respectively matched with the structures of the lower support truncated platform and the upper support truncated platform.

[0013] The positive and progressive effects of the utility model are:

A lifting column 2 is provided above the base 1. The lifting column 2 is sequentially sleeved with the positioning guide 3, the threaded control component 4, the lower support component 5, and the upper support component 6 from bottom to top. A plurality of internal support sheets 15 are provided between the lower support component 5 and the upper support component 6. The plurality of internal support sheets 15 are connected to the lifting column 2 by screws 7. A spring 8 is provided between the screws 7 and the internal support sheets 15.

[0023] The lower end of the positioning guide 3 is connected to the base 1, and a positioning pin 11 is provided on the positioning guide 3, and the positioning pin 11 is slidably connected to the lifting column 2 through the vertical slide groove 10. At the same time, the movable range of the lifting column 2 is limited by the positioning pin 11 to prevent the overall structure from decomposing.

[0024] The threaded control member 4 is threadedly connected to the lifting column 2. The lifting column 2 is lifted and lowered by rotating the threaded control member 4. The threaded control member 4 is composed of a cylindrical structure with threads on the inner side and a handle.

[0025] A lower supporting truncated platform 12 is disposed on the upper portion of the lower supporting member 5 , and a pin 13 is disposed on the lower supporting member 5 . The pin 13 is slidably connected to the lifting column 2 through a vertical sliding groove 10 .

[0026] A lifting thread 9 is provided in the middle of the lifting column 2, and a vertical slide groove 10 is provided on one side of the lifting column 2. The vertical slide groove 10 is used to cooperate with the pin 13 of the lower support member 5 and the positioning pin 11 on the positioning guide member 3.

[0027] An upper supporting truncated platform 14 is disposed at the lower portion of the upper supporting member 6 , and the upper supporting member 6 is fixedly connected to the lifting column 2 .

[0028] There are three inner support pieces 15 , and the inner support pieces 15 are matched with the structures of the lower support truncated platform 12 and the upper support truncated platform 14 respectively.

[0029] In the specific implementation, the upper support member 6 is fixed to the upper end of the lifting column 2, and the lifting column 2 is sequentially set with the upper support member 6, the lower support member 5, the threaded control member 4, and the positioning guide member 3 from top to bottom;

[0030] Install the pin 13 of the lower support member 5 so that one end of the pin 13 is placed in the vertical slide groove 10 of the lifting column 2 to limit the circumferential movement of the lower support member 5;

[0031] The threaded control member 4 is threadedly connected to the lifting column 2 via the lifting thread 9;

[0032] The positioning guide member 3 is installed with a positioning pin 11 so that one end of the positioning pin 11 is placed in the vertical slide groove 10 of the lifting column 2. The lower end of the positioning guide member 3 is fixedly connected to the base 1. The circumferential movement of the lifting column 2 is limited by the positioning guide member 3, and the axial movement of the lifting column 2 is limited by the positioning pin 11 and the vertical slide groove 10.

[0033] The inner support sheet 15 is installed between the upper support member 6 and the lower support member 5 , and is connected to the lifting column 2 through the action of the screws 7 and the springs 8 .

[0034] When in use, the lifting column 2 is raised so that one end of the inner support sheet 15 abuts against the lifting column 2 under the action of the spring 8. Figure 4 As shown, the structure shrinks to facilitate placement inside the thin-walled part to be processed;

[0035] When a thin-walled part needs to be clamped, the threaded control part 4 is rotated to drive the lifting column 2 to descend, and the inner support piece 15 is supported outward by the upper support truncated platform 14 and the lower support truncated platform 12 of the upper support part 6 and the lower support part 5, the screw 7 and the spring 8 to fix the thin-walled part.
