[0035] This embodiment provides a fixing tooling for fixing an annular workpiece, as Figures 1 - 3 shown. The fixing tooling includes a reference member 10, a driving assembly 20 and a supporting assembly 30. The reference member 10 is in a cylindrical shape; one end of the driving assembly 20 is connected to the outer periphery of the reference member 10, and the other end extends along the radial direction of the reference member 10. A plurality of driving assemblies 20 are arranged at intervals along the outer periphery of the reference member 10, and the plurality of driving assemblies 20 are located at the same horizontal height; a supporting assembly 30 is provided at one end of each of the plurality of driving assemblies 20 away from the reference member 10. The plurality of supporting assemblies 30 can abut against and support the inner peripheral surface of the annular workpiece, and the driving assembly 20 can move radially along the reference member 10 together with the supporting assembly 30 connected thereto, so that the plurality of supporting assemblies 30 can support annular workpieces with different diameters.

[0036] When using this tooling to fix the annular workpiece, the reference member 10 is in a cylindrical shape, and the supporting assemblies 30 are arranged at the same horizontal height along the outer periphery of the reference member 10 through the driving assemblies 20, so as to facilitate the annular workpiece to be sleeved on the outer peripheries of the plurality of supporting assemblies 30. By the supporting assemblies 30 abutting against and supporting the inner peripheral surface of the annular workpiece, it is ensured that the annular workpiece will not fall off; in addition, when dealing with annular workpieces with different diameters, the plurality of driving assemblies 20 drive the supporting assemblies 30 to move radially along the reference member 10, so that the plurality of supporting assemblies 30 can adapt to annular workpieces with different diameters and support and fix them. The operation is simple and convenient, and when fixing a plurality of annular workpieces with the same diameter in sequence, there is no need to recalibrate, which saves time and effort.

[0037] It should be noted here that in this embodiment, asFigure 1 and Figure 3 As shown in Figure 3 , the driving assembly 20 includes a lead screw 21 and a guide member 22. One end of the lead screw 21 is connected to the support assembly 30, and the other end extends into the reference member 10. When the lead screw 21 rotates, it can push the support assembly 30 to move radially along the reference member 10, and the end of the lead screw 21 that is not connected to the support assembly 30 can move radially inside the reference member 10; the guide member 22 is arranged at intervals above the lead screw 21, and one end is connected to the support assembly 30, and the other end extends into the reference member 10 and can move inside the reference member 10. When the lead screw 21 drives the support assembly 30 to move, it can play a guiding role for the support assembly 30 to ensure that it does not deviate from the preset direction.

[0038] When the support assembly 30 abuts against the inner peripheral surface of the annular workpiece, it provides pressure on the annular workpiece, thereby increasing the friction force between the two, and further ensuring that the annular workpiece does not fall. However, there is still a risk that the annular workpiece will fall due to excessive gravity. To solve this problem, as Figure 1 and Figure 3 shown, the support assembly 30 includes a support member 31. The side of the support member 31 facing away from the driving assembly 20 is a support surface 311. A support portion 312 is provided at the bottom end of the support member 31. When the support surface 311 abuts against the inner peripheral surface of the annular workpiece, the support portion 312 can support the bottom of the annular workpiece. By providing the support portion 312, the annular workpiece can be supported from the bottom, so that the gravity of the annular workpiece can be offset by the supporting force and the static friction force together, and further the situation of the annular workpiece falling can be avoided, ensuring a good fixing effect.

[0039] In addition, as Figure 1 and Figure 3 shown, the support assembly 30 further includes a pressing member 32. When the support portion 312 supports the annular workpiece, the pressing member 32 can be pressed against the top of the annular workpiece. This setting can enable the pressing member 32 and the support portion 312 to jointly clamp the annular workpiece, ensuring that the annular workpiece does not shake in the vertical direction, thereby producing a good fixing effect.

[0040] As Figure 1 and Figure 3As shown, the support assembly 30 includes a support frame 33, which is connected to the side of the support member 31 away from the support surface 311. The support surface 311 is provided with a plurality of adjustment holes 313 along the circumferential direction, and an adjustment member is provided in the adjustment hole 313. The adjustment member is connected to the support frame 33, and the support member 31 can adjust the flatness of the support surface 311. It should be noted here that the adjustment member is a bolt, and the adjustment hole 313 is a waist hole, and the inner circumference of the waist hole is provided with a thread. The adjustment member passes through the adjustment hole 313 and is connected to the support frame 33. When a certain position of the support surface 311 is more convex or more concave, the flatness of the support surface 311 is adjusted by adjusting the tightness of the bolt at the corresponding position, thereby ensuring the flatness of the support surface 311 and ensuring a good support effect.

[0041] In addition, if Figure 1 and Figure 2 As shown, a plurality of support rods 11 are arranged inside the reference part 10. The plurality of support rods 11 can improve the structural strength of the reference part 10 and ensure the roundness of the outer circumference of the reference part 10, thereby achieving a better fixing effect on the annular workpiece.

[0042] In this embodiment, the lead screw 21 and the guide member 22 are connected to the other side of the support frame 33, that is, the lead screw 21 can drive the support member 31 to move radially through the support frame 33. Figure 1 and Figure 3 As shown, the clamping member 32 can be detached from both sides of the support frame 33 along the width direction; the support member 31 can be detachably connected to the support frame 33. It should be noted here that a locking member 34 is provided at the top of the support member 31, and the support member 31 is connected to the support frame 33 through the locking member 34. The locking member 34 is a bolt, and the bolt has a simple structure and low price, which is convenient for mass production and installation. The clamping member 32 is fixed to both sides of the support frame 33 along the width direction by nuts, thereby simplifying the overall structure, facilitating subsequent maintenance and replacement, and also facilitating installation.

[0043] To further ensure the stability of the support assembly 30, as Figure 1 and Figure 3 As shown, the fixing fixture further includes a plurality of bases 40, one end of which is connected to the reference member 10 and is located at the bottom of the support assembly 30. The driving assembly 20 can drive the support assembly 30 to slide on the base 40 along the radial direction of the reference member 10. This structure can ensure the stability of the support assembly 30 when moving, and can also avoid the situation where the support assembly 30 is fixed close to the lead screw 21 and the guide member 22. In addition, as Figure 3 As shown, each base 40 is provided with scale marks, and when fixing annular workpieces of different diameters, the scale marks can be used to determine the distance between the support surface 311 and the circle of the reference part 10 at this time, so that the adjustment can be completed quickly and accurately.

[0044] In addition, as Figure 3 shown, a sliding groove 41 is provided on the base 40, and the support assembly 30 can slide within the sliding groove 41. By providing the sliding groove 41, it can be ensured that the support assembly 30 does not deviate from the preset route during the sliding process, thereby making the sliding process smoother. It should be noted here that the bottom end of the support frame 33 in the support assembly 30 is arranged within the sliding groove 41, and the bottom end of the support member 31 is higher than the sliding groove 41, that is, the lead screw 21 only drives the support frame 33 to slide within the sliding groove 41, so as to make the sliding process smoother.

[0045] In addition, for the convenience of installation, as Figure 1 shown, the fixing tooling further includes a plurality of connecting plates 50. The plurality of connecting plates 50 are evenly distributed on the outer periphery of the reference member 10, and the driving assembly 20, the support assembly 30, and the base 40 are all detachably arranged on the connecting plates 50. This structure avoids the problem of inconvenient installation of the driving assembly 20, the support member 31, and the base 40 on the outer periphery of the reference member 10. At the same time, the connecting plate 50 and the reference member 10 are detachably connected, which also facilitates subsequent maintenance and replacement.

[0046] In addition, as Figure 1 shown, a plurality of lifting lugs 12 are arranged on the top end of the reference member 10 along the circumferential direction. The lifting tool can lift the reference member 10 through the lifting lugs 12, thus facilitating handling.

[0047] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
