FIG. 1 is a schematic view illustrating an assembly of a fixture for a thin-walled part and the thin-walled part according to an embodiment of the present application; FIG. 2 is an exploded view of the clamp for a thin wall type part and the thin wall type part in the embodiment of FIG. 1; fig. 3 is a cross-sectional view of the support mechanism in the embodiment of fig. 1.

Referring to fig. 1 to 3, a fixture 200 for a thin-wall part provided in an embodiment of the present application includes a positioning seat 10, a positioning assembly 20, and a supporting mechanism 30.

The positioning assembly 20 is detachably mounted on the positioning socket 10, the positioning assembly 20 is used for positioning the thin-wall part 100 relative to the positioning socket 10, the supporting mechanism 30 is disposed between the positioning socket 10 and the thin-wall part 100, and the supporting mechanism 30 includes an elastic member 33 and a supporting member 34 (see fig. 3) arranged along a first direction (i.e., a direction a in fig. 1). One end of the elastic member 33 away from the supporting member 34 along the first direction a is connected to the positioning socket 10, and the elastic member 33 is configured to provide an elastic force away from the positioning socket 10 along the first direction a to support the supporting member 34. One end of the supporting member 34, which is far away from the elastic member 33 along the first direction a, is used for supporting the thin-walled part 100, and the supporting member 34 is configured to be capable of moving relative to the positioning seat 10 along the first direction a. .

The fixture 200 for the thin-wall parts enables the thin-wall parts 100 to be positioned on the positioning seat 10 by arranging the positioning assembly 20, so that the thin-wall parts 100 can be conveniently processed. By providing the supporting member 34 capable of moving relative to the positioning seat 10 along the first direction a, the distance between one end of the supporting member 34 for supporting the thin-wall part 100 and the positioning seat 10 is adjustable, so that the supporting mechanism 30 can be applied to different thin-wall parts 100. And because the supporting piece 34 is supported by the elastic force of the elastic piece 33 along the first direction, when the supporting piece 34 is used for different thin-wall parts 100, the supporting piece 34 can provide supporting force for the thin-wall parts 100, so that the supporting force received when the thin-wall parts 100 are positioned on the positioning seat 10 is improved. Therefore, the rigidity of the thin-wall part 100 in the machining process is improved, the vibration of the thin-wall part 100 and a cutter used for machining the thin-wall part 100 in the machining process is reduced, the machining precision of the thin-wall part 100 is improved, and the thin-wall part 100 has high universality for different thin-wall parts 100.

In actual use, the first direction a may be a vertical direction.

In some embodiments, the fixture 200 for thin-walled parts further includes a sensing device (not shown in the drawings), the sensing device is disposed on the supporting mechanism 30, and the sensing device is used for sensing the magnitude of the elastic force provided by the elastic member 33 and away from the positioning base 10 along the first direction a. Thus, the sensing device is arranged to sense the magnitude of the elastic force of the elastic member 33; in the using process, the deformation amount of the elastic member 33 can be adjusted according to the sensing value of the sensing device, so that the elastic force of the elastic member 33 is a preset elastic force value, and the distance between one end of the supporting member 34 far away from the elastic member 33 in the first direction a and the positioning seat 10 is a preset height value. Therefore, the problem that the distance between one end of the supporting member 34 away from the elastic member 33 and the positioning seat 10 in the first direction a is too small, which results in that the supporting member 34 supports the thin-wall part 100 in the first direction a insufficiently and reliably, and the problem that the distance between one end of the supporting member 34 away from the elastic member 33 and the positioning seat 10 in the first direction a is too large, which results in that the thin-wall part 100 is positioned excessively, which affects the processing precision of the thin-wall part 100, is avoided.

It should be noted that different thin-wall parts 100 correspond to different preset elastic values respectively. Before the fixture 200 for thin-wall parts is used, the preset height values corresponding to different thin-wall parts 100 can be obtained through multiple tests, and the preset elastic value corresponding to each preset height value is obtained through sensing of the sensing device. When in use, for the same thin-wall part 100, the position of the supporting member 34 in the first direction a relative to the positioning seat 10 is adjusted according to the preset elasticity value corresponding to the thin-wall part 100, so that the sensing value of the sensing device is the preset elasticity value corresponding to the thin-wall part 100. Wherein, the same thin-wall parts 100 refer to the thin-wall parts 100 with the same structure, shape and size,

it is understood that the predetermined elastic force value is an elastic force that the supporting mechanism 30 is reliably supported between the positioning seat 10 and the thin-wall type part 100, and the thin-wall type part 100 is not over-positioned. The predetermined elastic force value may be a predetermined elastic force range.

Alternatively, the positioning seat 10 may be made of steel. In one embodiment, the material of the positioning seat 10 is hardened and tempered 45 # steel, and the machining flatness of the positioning seat 10 reaches 0.005 μm. In use, the positioning base 10 can be mounted on a machine tool table.

In some embodiments, as shown in fig. 1 to 3, the supporting mechanism 30 further includes a seat body 32 disposed on the positioning seat 10, wherein the seat body 32 is used for accommodating the elastic element 33 and for partially accommodating the supporting element 34. The supporting element 34 is movably disposed through one end of the seat body 32 away from the positioning seat 10 along the first direction a, and one end of the elastic element 33 away from the supporting element 34 along the first direction a abuts against the seat body 32. In this way, by arranging the seat body 32 to accommodate the elastic element 33 and the end of the supporting element 34 connected to the elastic element 33, a certain limit effect is provided for the elastic element 33 and the supporting element 34 in the direction perpendicular to the first direction a, and the elastic element 33 and the supporting element 34 are prevented from being separated from each other, which results in a failure of supporting the thin-wall part 100.

It can be understood that, as shown in fig. 3, one end of the seat body 32 away from the positioning seat 10 along the first direction a is configured to fit the supporting member 34, for example, a shape in the end of the seat body 32 away from the positioning seat 10 along the first direction a is dominant to a shape of the supporting member 34, and a size in the end of the seat body 32 away from the positioning seat 10 along the first direction a is matched to a size of the supporting member 34, so as to avoid the supporting member 34 from shaking in a direction perpendicular to the first direction a, thereby improving a supporting stability of the supporting member 34 on the thin-wall part 100.

Optionally, the seat 32 and the support 34 are made of red copper, so as to further increase the rigidity of the thin-walled part 100 during machining and improve the machining precision.

In order to fix the base body 32 relative to the positioning seat 10, in some embodiments, as shown in fig. 2 to 4, the supporting mechanism 30 further includes a connecting member 31 penetrating through the positioning seat 10 and the base body 32 along the first direction a.

Optionally, the connecting member 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 through the connecting member 31, and thus the supporting mechanism 30 can be supported at different positions of the same thin-wall part 100 according to the use requirement, or supported at different thin-wall parts 100 according to the use requirement, so that the universality of the fixture 200 for thin-wall parts is further improved. For example, the support mechanisms 30 with different shapes and sizes may be arranged to correspond to different thin-wall parts 100, respectively, and the support mechanisms 30 may be replaced when machining is required to correspond to the thin-wall parts 100 to be machined, so as to meet the machining requirements of different thin-wall parts 100.

It will be appreciated that the end of the support 34 remote from the spud 10 in the first direction a may be provided with different shapes or sizes according to the use requirements to fit the shape and size of the corresponding thin-walled part 100.

In some embodiments, as shown in fig. 3, a first guiding portion 3221 is convexly disposed on one side of the seat body 32 abutting against the elastic element 33 in the first direction a, a second guiding portion 341 is convexly disposed on one side of the supporting element 34 abutting against the elastic element 33 in the first direction a, and two opposite ends of the elastic element 33 along the first direction a are respectively sleeved on the first guiding portion 3221 and the second guiding portion 341. In this manner, by providing the first guide portion 3221 and the second guide portion 341, respectively, to guide the compressive deformation of the elastic member 33 in the first direction a, the direction of the elastic force provided by the elastic member 33 is made parallel to the first direction a, thereby improving the accuracy of measurement and adjustment of the elastic force value of the elastic member 33.

Alternatively, the elastic member 33 may employ a spring.

In one embodiment, as shown in fig. 3, one end of the connecting member 31 far from the positioning socket 10 along the first direction a is inserted into the elastic member 33, and the connecting member 31 is spaced from the elastic member 33 in a direction perpendicular to the first direction a to avoid interference with the elastic member 33.

In some embodiments, as shown in fig. 3 to 4, the seat body 32 includes a base 322 and a sleeve 324 sequentially arranged along the first direction a, the base 322 is connected to the positioning seat 10 (see fig. 1), a first guiding portion 3221 is disposed on the base 322, the sleeve 324 is connected to one end of the base 322 far away from the positioning seat 10 in the first direction a, and the supporting element 34 is movably disposed in the sleeve 324. Thus, the base 322 and the sleeve 324 are separately arranged, so that the base 322 and the sleeve 324 can be conveniently processed, and the base 322 and the sleeve 324 can be conveniently assembled and disassembled, so that the elastic element 33 and the support element 34 can be conveniently assembled and disassembled with the seat body 32, and the maintenance or the replacement of the elastic element 33 and the support element 34 is convenient.

In some embodiments, as shown in fig. 3, a first position-limiting portion 342 is convexly disposed at an end of the supporting member 34 close to the base 322, a second position-limiting portion 3241 is convexly disposed on an inner wall of the sleeve 324, and the second position-limiting portion 3241 is configured to abut against a side of the first position-limiting portion 342 away from the base 322 in the first direction a. In this way, the first position-limiting portion 342 and the second position-limiting portion 3241 are disposed to avoid the inconvenience of the use caused by the separation of the supporting member 34 from the sleeve 324.

In order to increase the rigidity of the supporting mechanism 30, in some embodiments, as shown in fig. 3 to 4, the supporting mechanism 30 further includes an abutting member 36, the abutting member 36 is disposed through the seat 32 along a direction perpendicular to the first direction a, and the abutting member 36 is configured to abut against the supporting member 34. By providing the abutting piece 36 to abut against the support piece 34 in this way, the movement of the support piece 34 relative to the positioning seat 10 in the first direction a is blocked, and the rigidity of the support mechanism 30 is improved, thereby improving the rigidity of the thin-walled part 100 during the machining process.

It should be understood that when the abutment 36 abuts against the support 34, the abutment 36 is configured to provide a frictional force that secures the support 34 relative to the seat 32.

Specifically, the abutting member 36 is screwed with the seat body 32, so that the abutting member 36 can be fixed relative to the seat body 32, and the supporting member 34 is reliably fixed relative to the seat body 32. In addition, due to the threaded connection between the abutting piece 36 and the seat body 32, the abutting piece 36 can be screwed to change the relative position of the abutting piece 36 and the seat body 32 along the axial direction thereof, so as to adjust the length of the abutting piece 36 extending into the seat body 32, so that the abutting piece 36 can lock or release the supporting piece 34, so as to realize the reliable support of the supporting mechanism 30 on the thin-wall part 100, or realize the adjustable distance between one end of the supporting piece 34 far from the elastic piece 33 and the positioning seat 10 along the first direction a.

In an actual use process, when the thin-walled part 100 needs to be processed, the abutting part 36 is screwed out of the seat body 32 to adjust a distance between one end of the support part 34, which is far away from the elastic part 33 along the first direction a, and the positioning seat 10 until the elastic force of the elastic part 33 sensed by the sensing device is a preset elastic force value corresponding to the thin-walled part 100, and the abutting part 36 is screwed into the seat body 32, so that the abutting part 36 locks the support part 34. Then, the thin-walled component 100 is assembled and positioned on the jig 200 for thin-walled components, and is machined.

Specifically, as shown in fig. 3 to 4, the abutting element 36 includes a rod 361 passing through the seat body 32, and an operating portion 362 connected to an end of the rod 361 far from the support 34 along the axial direction thereof, wherein a radial dimension of the operating portion 362 is larger than a radial dimension of the rod 361, so as to increase torque when the abutting element 36 is screwed by the operating portion 362.

In order to improve the positioning accuracy of the thin-wall part 100, in some embodiments, as shown in fig. 1-2, a plurality of process bosses 101 are provided on the thin-wall part 100, the positioning assembly 20 includes first positioning members 21 corresponding to the process bosses 101, and each first positioning member 21 is disposed between the positioning seat 10 and the corresponding process boss 101 along the first direction a, so as to position the thin-wall part 100 relative to the positioning seat 10. In this way, the process boss 101 is arranged on the thin-wall part 100 to serve as a processing reference, and the first positioning element 21 is used for positioning the corresponding process boss 101, so that the deformation of the thin-wall part 100 in the processing process is reduced, and the processing precision of the thin-wall part 100 is further improved. In addition, the process boss 101 and the corresponding first positioning piece 21 are convenient to position and align, operation is convenient, and the operation time for positioning the thin-wall part 100 on the positioning seat 10 is shortened, so that the processing efficiency of the thin-wall part 100 is improved.

In the actual use process, before the thin-wall part 100 is machined, the process boss 101 is additionally arranged on the thin-wall part 100 according to the use requirement, and after the machining is finished, the process boss 101 on the thin-wall part 100 is removed. In addition, other special-shaped parts can be positioned by adding the process boss 101 and the like.

It will be appreciated that the location and number of the tooling bosses 101 on the various thin-walled parts 100 may be configured as desired for use. The position and the number of the first positioning members 21 can be adjusted according to the corresponding thin-wall type part 100.

In some embodiments, as shown in fig. 1-2, the positioning assembly 20 further includes a first fastening member 22 and a first locking member 23, each of which corresponds one-to-one to the first positioning member 21. The first fastening member 22 penetrates through the positioning seat 10 and the corresponding first positioning member 21 along the first direction a, one end of the first fastening member 22, which is away from the positioning seat 10 in the first direction a, extends out of the first positioning member 21, and the first fastening member 23 is sleeved on one end of the first fastening member 22, which is away from the positioning seat 10 in the first direction a, so as to tightly press and fix the first positioning member 21 on the positioning seat 10. In this way, the first fastening member 22 and the first locking member 23 are arranged to fix the thin-wall part 100 and the first positioning member 21 relative to the positioning seat 10. In addition, the clamping force on the thin-wall part 100 can be increased by utilizing the pretightening force after the first fastening piece 22 and the first locking piece 23 are connected, so that the shock absorption on the thin-wall part 100 is further realized.

In the actual use process, a preset torque value can be determined according to a plurality of tests, and the first locking member 23 is assembled on the first fastening member 22 through a torque wrench at the preset torque value during processing, so that the first locking member 23 exerts a preset pretightening force on the thin-wall part 100. The preset pretightening force is a pretightening force for reliably clamping the thin-wall part 100 between the first locking member 23 and the first positioning member 21 and avoiding over-positioning of the thin-wall part 100.

In some embodiments, as shown in fig. 1-2, the positioning assembly 20 includes at least one second positioning member 24 disposed on the positioning seat 10, and the fixture 200 for thin-walled parts further includes a plurality of second fastening members 25, where the second fastening members 25 are disposed in the second positioning member 24 and the thin-walled part 100 along a direction perpendicular to the first direction a. In this manner, by providing the second positioning member 24 and the second fastening member 25, the rigidity of the thin-walled part 100 is further improved, and the thin-walled part 100 is further damped.

Therefore, the clamp 200 for the thin-wall parts can improve the machining efficiency, the positioning accuracy and the machining accuracy of the thin-wall parts 100, the deformation of the thin-wall parts 100 is small, and the clamp can be applied to different thin-wall parts 100 or special-shaped parts.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.
