[0002] Anti-deformation tooling is a tooling equipment used to ensure that the workpiece does not deform during the manufacturing and processing process, thereby ensuring the processing quality of the workpiece.

[0003] Thin-walled cylinder parts made of ZL201 (ZL201 is also known as ZAlCu5Mn, a cast aluminum alloy) such as Figure 1 As shown, the window 200 will be processed on the cylinder 100 according to the needs. The processed window 200 will be insufficiently invalidated, and the residual internal stress of the window 200 processing process will be released. The position of the cylinder 100 where the window 200 is set will shrink radially inward, causing the size of the window 200 to change over time. This phenomenon is particularly significant in the thin-walled cylinder with a large window structure, which will cause product assembly difficulties or often cause delays due to size rework. Therefore, a tooling that can prevent the deformation of thin-walled cylinder parts is needed. Summary of the invention

[0030] Combine the following Figure 1-Figure 7 The present invention is described in detail.

[0031] Example

[0032] A deformation prevention tool for thin-walled cylindrical parts includes a first support mechanism 2 for supporting the inner wall of the cylindrical part 100, a connecting portion 3 is connected to the side wall of the first support mechanism 2, and the first support mechanism 2 is detachably connected to a second support mechanism 4 for supporting the edge of a window 200 through the connecting portion 3.

[0033] The first supporting mechanism 2 supports the inner wall position of the barrel 100 where the window 200 is opened to limit the inward contraction of the barrel 100 , and the second supporting mechanism 4 supports the local edge of the window 200 to further limit the change in the size of the window 200 .

[0034] The first supporting mechanism 2 and the second supporting mechanism 4 both include a mounting disk 401, on which a mounting shaft 405 is axially mounted, and on which a plurality of sliding plates 403 are radially slidably arranged along the mounting shaft 405, and a top block 402 is arranged at one end of the sliding plate 403 away from the mounting shaft 405, and a turntable 406 is rotatably mounted on the mounting shaft 405, and a spiral protrusion 407 is arranged on the end surface of the turntable 406 close to the sliding plate 403, and an arc groove 404 cooperating with the spiral protrusion 407 is arranged on the sliding plate 403.

[0035] The difference between the first support mechanism 2 and the second support mechanism 4 lies in the different number of sliding plates 403 and the structure of the top block 402. The number of sliding plates 403 of the first support mechanism 2 is at least 3, and the optimal number is 3. While ensuring the supporting function, the angle between the two sliding plates 403 is increased so that the two sliding plates 403 are abutted against the two sides of the window 200; the second support mechanism 4 is provided with at least four sliding plates 403, and the four sliding plates 403 support the four sides of the window 200 respectively. The top blocks 402 located on the upper and lower sides of the window 200 are provided with first steps 410 for abutting against the inner wall of the cylinder 100, and the top blocks 402 located on the left and right sides of the window 200 are provided with second steps 411 for abutting against the outer wall of the cylinder 100. The first step 410 is arranged outwardly, and the second step 411 is arranged inwardly, wherein the first step 410 can prevent the upper and lower horizontal sides of the window 200 from bending and deforming inwardly; due to the supporting effect of the first supporting mechanism 2, the vertical sides on the left and right sides of the window 200 will not shrink and deform inwardly, so the second step 411 is arranged inwardly to prevent the vertical sides on the left and right sides of the window 200 from being abutted by the first supporting mechanism 2 and deforming outwardly; when in use, the first step 410 abuts against the inner wall of the cylinder 100, and the second step 411 abuts against the outer wall of the cylinder 100, and they cooperate with each other to limit the deformation of the window 200.

[0036] By rotating the turntable 406, the spiral protrusion 407 cooperates with the arc groove 404 to drive the sliding plate 403 to move radially to adjust the position, so that multiple top blocks 402 can simultaneously abut against the inner wall of the cylinder 100 or the edge of the window 200 for support. The turntable 406 is provided with a plug hole 408 to facilitate the use of a tool to insert into the plug hole 408 to rotate the turntable 406.

[0037] The top block 402 is made of polyoxymethylene or polytetrafluoroethylene, and a rubber soft protective sheet is attached to the end surface of the top block 402 to ensure that the product will not be scratched during use.

[0038] The connecting portion 3 includes an arc-shaped clamping block 301 that is clamped and fixed on the first supporting mechanism 2. The arc-shaped clamping block 301 is connected to a connecting tube 302 that is radially arranged along the mounting axis 405 of the first supporting mechanism 2. A guide groove 303 is arranged in the connecting tube 302. The mounting axis 405 of the second supporting mechanism 4 passes through the mounting plate 401 and extends into the connecting tube 302. A positioning key 409 that cooperates with the guide groove 303 is arranged on the mounting axis 405 of the second supporting mechanism 4. A screw (not shown in the figure) that abuts against the side wall of the mounting axis 405 is threadedly arranged on the connecting tube 302.

[0039] After the installation shaft 405 of the second supporting mechanism 4 extends into the connecting tube 302, the positioning key 409 is inserted into the guide groove 303 to prevent the installation shaft 405 and the connecting tube 302 from rotating relative to each other, and finally the installation shaft 405 is locked by the screw.

[0040] The arc-shaped clamping block 301 is detachably connected to the mounting plate 401 of the first supporting mechanism 2 via a screw rod, so as to facilitate the disassembly and assembly of the tooling.

[0041] The top block 402 is detachably connected to the sliding plate 403 via a screw rod. Different top blocks 402 can be replaced according to usage requirements, so that the top block 402 can be abutted against the inner wall of the barrel 100 and the edge of the window 200 of different sizes.

[0042] A pressure sensor (not shown in the figure) is provided on the end surface of the top block 402 away from the sliding plate 403. During the support process of the first supporting mechanism 2 and the second supporting mechanism 4, the pressure sensor can provide real-time feedback of the working pressure curve to avoid abnormalities in the press-fitting process. The pressure sensor can be a pressure strain gauge, which is pasted on the end surface of the top block 402 and can be removed when not in use.

[0043] The bottom of the first supporting mechanism 2 is connected with a lifting mechanism 1. The positions of the first supporting mechanism 2 and the second supporting mechanism 4 are adjusted by the lifting mechanism 1, so that the first supporting mechanism 2 and the second supporting mechanism 4 can be supported at appropriate positions.

[0044] The lifting mechanism 1 includes a base 101 and a connecting seat 104 spaced apart from each other. Two first support arms 102 are hingedly connected to the base 101. One end of the first support arm 102 away from the base 101 is rotatably connected to a rotating shaft 105. The rotating shaft 105 is rotatably connected to a second support arm 103 hinged to the connecting seat 104. The two rotating shafts 105 are threadedly connected to positive and negative screw rods 106. By rotating the positive and negative screw rods 106, the two rotating shafts 105 are driven to move relative to each other, thereby controlling the deflection of the first support arm 102 and the second support arm 103 to adjust the lifting and lowering of the connecting seat 104.

[0045] The ends of the forward and reverse screw rods 106 are connected with hand wheels 107 , so that the forward and reverse screw rods 106 can be rotated conveniently using the hand wheels 107 .

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
