[0044] Figure 1 This is a schematic diagram of assembling a fixture for thin-walled parts and thin-walled parts in one embodiment of the present application; Figure 2 for Figure 1 An exploded view of a fixture for thin-walled parts and thin-walled parts in the illustrated embodiment; Figure 3 for Figure 1 Cross-sectional view of the support mechanism in the illustrated embodiment.

[0045] See Figure 1-3 In one embodiment of the present application, a fixture 200 for thin-walled parts includes a positioning seat 10, a positioning assembly 20 and a support mechanism 30.

[0046] The positioning assembly 20 is detachably mounted on the positioning seat 10. The positioning assembly 20 is used to position the thin-walled part 100 relative to the positioning seat 10. The support mechanism 30 is provided between the positioning seat 10 and the thin-walled part 100, and the support mechanism 30 includes a first direction (i.e., Figure 1The elastic member 33 and the support member 34 (see Figure 3 The end of the elastic member 33 that is away from the support member 34 in the first direction A is connected to the positioning seat 10. The elastic member 33 is configured to provide a spring force that moves away from the positioning seat 10 in the first direction A to support the support member 34. The end of the support member 34 that is away from the elastic member 33 in the first direction A is used to support the thin-walled component 100, and the support member 34 is configured to be movable in the first direction A relative to the positioning seat 10.

[0047] The fixture 200 for thin-walled parts, by providing a positioning assembly 20, positions a thin-walled part 100 on the positioning seat 10, facilitating processing of the thin-walled part 100. By providing a support member 34 that is movable relative to the positioning seat 10 along a first direction A, the distance between the end of the support member 34 supporting the thin-walled part 100 and the positioning seat 10 is adjustable, thereby enabling the support mechanism 30 to be adapted for different thin-walled parts 100. Furthermore, because the support member 34 is supported by the elastic force of the elastic member 33 along the first direction, the support member 34 can provide support for the thin-walled part 100 regardless of the thin-walled part 100 being used, thereby improving the support force applied to the thin-walled part 100 when positioned on the positioning seat 10. This improves the rigidity of the thin-walled parts 100 during processing, reduces the vibration of the thin-walled parts 100 and the tools used to process the thin-walled parts 100 during processing, improves the processing accuracy of the thin-walled parts 100, and has high versatility for different thin-walled parts 100.

[0048] In actual use, the first direction A may be a vertical direction.

[0049] In some embodiments, the fixture 200 for thin-walled parts further includes a sensing device (not shown) disposed on the support mechanism 30 and configured to sense the magnitude of the elastic force exerted by the elastic member 33 in the first direction A away from the positioning seat 10. Thus, by providing the sensing device to sense the magnitude of the elastic force of the elastic member 33, the deformation of the elastic member 33 can be adjusted based on the value sensed by the sensing device, ensuring that the elastic force of the elastic member 33 reaches a predetermined value. This in turn allows the distance between the end of the support member 34 in the first direction A away from the elastic member 33 and the positioning seat 10 to reach a predetermined height. This prevents the distance between the end of the support member 34 in the first direction A away from the elastic member 33 and the positioning seat 10 from being too small, thereby preventing the support member 34 from providing unreliable support for the thin-walled part 100 in the first direction A. It also prevents the distance between the end of the support member 34 in the first direction A away from the elastic member 33 and the positioning seat 10 from being too large, thereby preventing the thin-walled part 100 from being over-positioned and affecting the machining accuracy of the thin-walled part 100.

[0050] It should be noted that different thin-walled parts 100 correspond to different preset elastic force values. Before the fixture 200 for thin-walled parts is used, the preset height values corresponding to different thin-walled parts 100 can be obtained through multiple tests, and the preset elastic force value corresponding to each preset height value can be sensed by the sensing device. When in use, for the same thin-walled part 100, according to the preset elastic force value corresponding to this thin-walled part 100, the position of the support member 34 relative to the positioning seat 10 in the first direction A is adjusted so that the sensing value of the sensing device is the preset elastic force value corresponding to this thin-walled part 100. Among them, the same thin-walled part 100 refers to thin-walled parts 100 with the same structure, shape and size,

[0051] It is understood that the preset elastic force value is an elastic force that enables the support mechanism 30 to be reliably supported between the positioning seat 10 and the thin-walled part 100 and prevents the thin-walled part 100 from being over-positioned. The preset elastic force value can be a preset elastic force range.

[0052] Optionally, the material of the positioning seat 10 can be steel. In one embodiment, the material of the positioning seat 10 is quenched and tempered 45 steel, and the processing flatness of the positioning seat 10 reaches 0.005 microns. When in use, the positioning seat 10 can be installed on a machine tool workbench.

[0053] In some embodiments, combined Figure 1-3 As shown, the support mechanism 30 further includes a seat body 32 disposed on the positioning seat 10. The seat body 32 is used to accommodate the elastic member 33 and partially accommodate the support member 34. The support member 34 is movably disposed through the end of the seat body 32 that is away from the positioning seat 10 along the first direction A. The end of the elastic member 33 that is away from the support member 34 along the first direction A abuts against the seat body 32. Thus, by providing the seat body 32 to accommodate the elastic member 33 and the end of the support member 34 connected to the elastic member 33, a certain degree of position limiting is provided for the elastic member 33 and the support member 34 in a direction perpendicular to the first direction A, preventing the elastic member 33 and the support member 34 from separating from each other, thereby preventing the support of the thin-walled part 100 from failing.

[0054] It is understandable that if Figure 3 As shown, the end of the seat body 32 away from the positioning seat 10 along the first direction A is configured to adapt to the support member 34. For example, the shape of the end of the seat body 32 away from the positioning seat 10 along the first direction A is dominated by the shape of the support member 34, and the size of the end of the seat body 32 away from the positioning seat 10 along the first direction A is adapted to the size of the support member 34 to avoid the support member 34 from shaking in a direction perpendicular to the first direction A, thereby improving the support stability of the support member 34 on the thin-walled parts 100.

[0055] Optionally, the base 32 and the support member 34 are both made of copper to further increase the rigidity of the thin-walled part 100 during processing and improve the processing accuracy.

[0056] Figure 4 for Figure 1 Exploded view of the support mechanism in the illustrated embodiment.

[0057] In order to fix the seat body 32 relative to the positioning seat 10, in some embodiments, as Figure 2-4 As shown, the support mechanism 30 further includes a connecting member 31 that passes through the positioning seat 10 and the seat body 32 along the first direction A.

[0058] Optionally, the connector 31 is detachably connected to the positioning seat 10, so that the seat body 32 can be installed at different positions of the positioning seat 10 via the connector 31, thereby enabling the support mechanism 30 to support different positions of the same thin-walled part 100 according to usage requirements, or to support different thin-walled parts 100 according to usage requirements, thereby further improving the versatility of the fixture 200 for thin-walled parts. For example, support mechanisms 30 of different shapes and sizes can be provided to correspond to different thin-walled parts 100, and the support mechanism 30 can be replaced when processing is required to correspond to the thin-walled part 100 to be processed, thereby meeting the processing requirements of different thin-walled parts 100.

[0059] It is understandable that the end of the support member 34 away from the positioning seat 10 along the first direction A can be set to different shapes or sizes according to usage requirements to adapt to the shape and size of the corresponding thin-walled part 100.

[0060] In some embodiments, such as Figure 3 As shown, the base 32 has a first guide portion 3221 protruding from one side thereof that abuts the elastic member 33 in the first direction A. The support member 34 has a second guide portion 341 protruding from one side thereof that abuts the elastic member 33 in the first direction A. The elastic member 33 is sleeved on the first guide portion 3221 and the second guide portion 341 at opposite ends thereof along the first direction A. Thus, by providing the first guide portion 3221 and the second guide portion 341, respectively, the compression deformation of the elastic member 33 in the first direction A is guided, and the direction of the elastic force provided by the elastic member 33 is parallel to the first direction A, thereby improving the accuracy of measuring and adjusting the elastic force of the elastic member 33.

[0061] Optionally, the elastic member 33 may be a spring.

[0062] In one embodiment, Figure 3 As shown, one end of the connecting member 31 away from the positioning seat 10 along the first direction A is inserted into the elastic member 33, and the connecting member 31 is spaced relative to the elastic member 33 in a direction perpendicular to the first direction A to avoid interference with the elastic member 33.

[0063] In some embodiments, such as Figure 3-4 As shown, the seat body 32 includes a base 322 and a sleeve 324 arranged in sequence along the first direction A. The base 322 and the positioning seat 10 (see Figure 1 ), and a first guide portion 3221 is provided on the base 322. A sleeve 324 is connected to one end of the base 322 in the first direction A away from the positioning seat 10, and the support member 34 is movably inserted into the sleeve 324. In this way, by providing the base 322 and the sleeve 324 as separate bodies, the base 322 and the sleeve 324 can be processed separately and the base 322 and the sleeve 324 can be easily assembled and disassembled. As a result, the elastic member 33 and the support member 34 can be easily assembled and disassembled from the base body 32, making it convenient to maintain or replace the elastic member 33 and the support member 34.

[0064] In some embodiments, such as Figure 3 As shown, a first stopper 342 is provided on one end of the support member 34 near the base 322, and a second stopper 3241 is provided on the inner wall of the sleeve 324. The second stopper 3241 is configured to abut against a side of the first stopper 342 that is away from the base 322 in the first direction A. Thus, by providing the first stopper 342 and the second stopper 3241, the support member 34 is prevented from being separated from the sleeve 324, which would cause inconvenience in use.

[0065] In order to improve the rigidity of the support mechanism 30, in some embodiments, Figure 3-4 As shown, the support mechanism 30 further includes an abutment member 36, which is provided through the base body 32 in a direction perpendicular to the first direction A. The abutment member 36 is configured to abut the support member 34. Thus, by providing the abutment member 36 to abut against the support member 34, the support member 34 is prevented from moving relative to the positioning base 10 in the first direction A, thereby improving the rigidity of the support mechanism 30 and thereby improving the rigidity of the thin-walled part 100 during processing.

[0066] It should be understood that when the abutting member 36 abuts against the supporting member 34 , the abutting member 36 is configured to provide a friction force that fixes the supporting member 34 relative to the seat body 32 .

[0067] Specifically, the abutment member 36 is threadedly connected to the base body 32 so that the abutment member 36 can be fixed relative to the base body 32, thereby reliably fixing the support member 34 relative to the base body 32. In addition, since the abutment member 36 is threadedly connected to the base body 32, the relative position of the abutment member 36 along its axial direction with respect to the base body 32 can be changed by screwing the abutment member 36, thereby adjusting the length of the abutment member 36 extending into the base body 32. This allows the abutment member 36 to lock or loosen the support member 34, thereby achieving reliable support of the thin-walled part 100 by the support mechanism 30, or achieving adjustable distance between the end of the support member 34 away from the elastic member 33 along the first direction A and the positioning seat 10.

[0068] In actual use, when a thin-walled part 100 needs to be processed, the abutment 36 is screwed out of the base 32 to adjust the distance between the end of the support member 34 away from the elastic member 33 along the first direction A and the positioning base 10 until the elastic force of the elastic member 33 sensed by the sensing device reaches a preset elastic force value corresponding to the thin-walled part 100. The abutment 36 is then screwed into the base 32 to lock the abutment 36 with the support member 34. Then, the thin-walled part 100 is assembled and positioned on the fixture 200 for thin-walled parts for processing.

[0069] Specifically, if Figure 3-4 As shown, the abutment 36 includes a rod body 361 passed through the seat body 32, and an operating part 362 connected to one end of the rod body 361 away from the support member 34 along its own axial direction. The radial dimension of the operating part 362 is larger than the radial dimension of the rod body 361, so as to increase the torque when the abutment 36 is screwed through the operating part 362.

[0070] In order to improve the positioning accuracy of thin-walled parts 100, in some embodiments, such as Figure 1-2 As shown, a thin-walled part 100 is provided with a plurality of process bosses 101, and the positioning assembly 20 includes first positioning members 21 corresponding one to one with the process bosses 101. Each first positioning member 21 is provided between the positioning seat 10 and the corresponding process boss 101 along the first direction A to position the thin-walled part 100 relative to the positioning seat 10. In this way, by providing the process bosses 101 on the thin-walled part 100 as a processing reference, and positioning the corresponding process bosses 101 by the first positioning members 21, deformation of the thin-walled part 100 during processing is reduced, and the processing accuracy of the thin-walled part 100 is further improved. In addition, since the process bosses 101 and the corresponding first positioning members 21 are easy to position and align, operation is convenient, and the operation time for positioning the thin-walled part 100 on the positioning seat 10 is shortened, thereby improving the processing efficiency of the thin-walled part 100.

[0071] In actual use, before processing the thin-walled part 100, a process boss 101 is added to the thin-walled part 100 according to the use requirements. After processing, the process boss 101 on the thin-walled part 100 is removed. In addition, other special-shaped parts can also be positioned by adding process bosses 101.

[0072] It is understandable that the position and number of the process bosses 101 on different thin-walled parts 100 can be set according to the use requirements. The position and number of the first positioning members 21 can be adjusted according to the corresponding thin-walled parts 100.

[0073] In some embodiments, such as Figure 1-2As shown, the positioning assembly 20 also includes a first fastener 22 and a first locking member 23 that correspond to the first positioning member 21 one by one. The first fastener 22 is inserted into the positioning seat 10 and the corresponding first positioning member 21 along the first direction A, and the end of the first fastener 22 away from the positioning seat 10 in the first direction A extends out of the first positioning member 21. The first locking member 23 is sleeved on the end of the first fastener 22 away from the positioning seat 10 in the first direction A to press and fix the first positioning member 21 on the positioning seat 10. In this way, by providing the first fastener 22 and the first locking member 23, the thin-walled part 100 and the first positioning member 21 are both fixed relative to the positioning seat 10. In addition, the pre-tightening force after the first fastener 22 and the first locking member 23 are connected can also be used to increase the clamping force on the thin-walled part 100, thereby further reducing the shock of the thin-walled part 100.

[0074] In actual use, a preset torque value can be determined based on multiple tests. During processing, the first locking member 23 can be assembled on the first fastening member 22 using a torque wrench at the preset torque value, so that the first locking member 23 exerts a preset pre-tightening force on the thin-walled part 100. The preset pre-tightening force is a pre-tightening force that reliably clamps the thin-walled part 100 between the first locking member 23 and the first positioning member 21 and prevents the thin-walled part 100 from being over-positioned.

[0075] In some embodiments, such as Figure 1-2 As shown, the positioning assembly 20 includes at least one second positioning member 24 disposed on the positioning seat 10. The fixture 200 for thin-walled parts also includes a plurality of second fasteners 25. The second fasteners 25 are inserted through the second positioning member 24 and the thin-walled part 100 in a direction perpendicular to the first direction A. In this way, the second positioning member 24 and the second fasteners 25 are provided to further improve the rigidity of the thin-walled part 100, thereby further reducing vibration of the thin-walled part 100.

[0076] Therefore, the fixture 200 for thin-walled parts provided in this application can improve the processing efficiency, positioning accuracy and processing accuracy of thin-walled parts 100, and the deformation of thin-walled parts 100 is small, and it can also be suitable for different thin-walled parts 100 or special-shaped parts.

[0077] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
