[0030] In the embodiments of the utility model, as shown in Figures 1 to 5 The utility model discloses a scroll spring tooling which comprises a mounting plate 10, a mounting frame 20, a rotating plate 30 and a fixing bolt 40. The mounting plate 10 is provided with a mounting hole. The mounting frame 20 is internally provided with a mounting cavity 21 which penetrates through both ends of the mounting frame 20. The cavity wall of the mounting cavity 21 is provided with a first mounting groove 22. One end of the mounting frame 20 is mounted on the mounting plate 10, and the mounting cavity 21 is communicated with the mounting hole. One end of the rotating plate 30 is provided with a rotating part 31, and the other end is provided with a mounting rod 32 at a position corresponding to the rotating part 31. The peripheral surface of the mounting rod 32 is provided with a second mounting groove 33, and the mounting rod 32 is provided with a first threaded hole 34. The rotating plate 30 is arranged at the other end of the mounting frame 20, and the mounting rod 32 is located in the mounting cavity 21 and faces the mounting hole. The fixing bolt 40 is provided with a threaded rod part which penetrates through the mounting hole and is screwed into the first threaded hole 34.

[0031] Specifically, in use, the mounting frame 20 is first mounted on the mounting plate 10, and then the scroll spring to be tested is mounted in the mounting cavity 21, and the outer end of the scroll spring is clamped in the first mounting groove 22. Then, the rotating plate 30 is placed on the mounting frame 20, and the inner end of the scroll spring is clamped into the second mounting groove 33. The fixing bolt 40 is screwed into the first threaded hole 34 through the mounting hole to mount and fix the rotating plate 30. Subsequently, the rotating part 31 can be rotated by the torque wrench, and the rotation angle and the torsion can be recorded, and the reset condition of the rotating plate 30 can be observed, so as to test the scroll spring.

[0032] The utility model discloses technical scheme is through setting up mounting plate 10, mounting frame 20, rotating plate 30 and fixed bolt 40, wherein, set up mounting hole on mounting plate 10, set up the installation cavity 21 of passing through both ends on mounting frame 20, and set up the first installation slot 22 on the cavity wall of installation cavity 21. Set up rotating part 31 on one end of rotating plate 30, and set up mounting rod 32 corresponding rotating part 31 on the other end, set up the second installation slot 33 and first threaded hole 34 on mounting rod 32. In this way, mounting frame 20 can be installed on mounting plate 10, and installation cavity 21 is communicated with mounting hole at the same time. The volute spring to be tested is installed in installation cavity 21, and the outer end of the volute spring is clamped in the first installation slot 22, then rotating plate 30 is installed on mounting frame 20, and after installation, mounting rod 32 is located in installation cavity 21, and the inner end of the volute spring is clamped in the second installation slot 33. Then, the shank of fixed bolt 40 is screwed to the first threaded hole 34 through the mounting hole to install and fix rotating plate 30. In this way, rotating part 31 can be rotated by torque wrench, so that the volute spring is elastically deformed, and the rotation angle and torsion of the torque wrench are recorded, then the reset condition of rotating plate 30 is observed, so that the volute spring is tested. Compared with the structure that the auxiliary rod and the sensor are arranged in the volute spring tooling and matched, the volute spring tooling structure of the present scheme is simpler, and the operation difficulty is smaller. Without complex sensor installation and debugging process, the technical requirement of operation is reduced. At the same time, the simple structure also makes the maintenance of the tooling more convenient, reduces the test interruption time caused by faults, and can significantly improve the test efficiency of the volute spring.

[0033] In some embodiments, the volute spring tooling further comprises a positioning nut 60, which is screwed to the shank of the fixed bolt 40 and abuts against one side of the mounting plate 10 away from the mounting frame 20. Specifically, the positioning nut 60 can effectively prevent the fixed bolt 40 from loosening or falling off during testing. After testing one volute spring is completed, when the rotating plate 30 and the tested volute spring are disassembled, the positioning nut 60 can ensure that the fixed bolt 40 does not easily fall off from the mounting plate 10, improving the test efficiency and reducing the time for reinstalling the fixed bolt 40, thereby improving the test efficiency.

[0034] In some embodiments, the volute spring tooling further comprises a support base 50, and the mounting plate 10 is vertically installed on the support base 50. Specifically, by installing the mounting plate 10 on the support base 50 and placing the support base 50 on the plane of the workbench, the mounting plate 10 can be kept in a vertical state during testing, which makes it more convenient to use the torque wrench to rotate the rotating part 31 for testing, and there is no need to additionally provide a structure for fixing the mounting plate 10 on the workbench.

[0035] In some embodiments, the installation plate 10, the mounting frame 20 and the rotating plate 30 are all made of metal. Specifically, when the installation plate 10, the mounting frame 20 and the rotating plate 30 are made of metal, the thermal expansion coefficient of the volute spring tool is small, and even if the ambient temperature fluctuates, the test accuracy is not affected. Moreover, such a volute spring tool has good wear resistance, less wear during use, and long service life. Further, the installation plate 10, the mounting frame 20 and the rotating plate 30 can be made of aluminum alloy, stainless steel, etc. In addition, in other embodiments, the installation plate 10, the mounting frame 20 and the rotating plate 30 can also be made of hard plastic. Specifically, when the material is hard plastic, it is light in weight, easy to carry and operate, and the cost is relatively low.

[0036] In some embodiments, the mounting frame 20 is provided with a plurality of second threaded holes 23 on the end face facing the installation plate 10, the installation plate 10 is provided with a plurality of mounting through holes 11 corresponding to the plurality of second threaded holes 23, and a plurality of threaded fasteners are screwed into the second threaded holes 23 through the mounting through holes 11 to fix the installation plate 10 and the mounting frame 20. Specifically, the mounting frame 20 is installed on the installation plate 10 by the threaded fasteners, and the mounting frame 20 and the installation plate 10 are fixed more firmly. Compared with the mounting frame 20 and the installation plate 10 being integrally formed, the mounting frame 20 and the installation plate 10 are separately formed, which is simpler and facilitates replacement of the mounting frame 20 when the wear degree of the mounting frame 20 is too large.

[0037] In some embodiments, the rotating plate 30 is provided with a limiting ring 35 with a shape matched with the mounting frame 20 on the outer periphery facing the mounting frame 20. Specifically, when the rotating plate 30 is installed on the mounting frame 20, the limiting ring 35 is sleeved on the mounting frame 20, which avoids radial movement of the rotating plate 30 relative to the mounting frame 20, and makes the installation of the rotating plate 30 and the mounting frame 20 more firm.

[0038] In some embodiments, the mounting frame 20 and the rotating plate 30 have the same radial dimension, and the mounting frame 20 is provided with a limiting groove 24 matched with the structure of the limiting ring 35. Specifically, after the rotating plate 30 is installed on the mounting frame 20, the outer peripheral surface of the rotating plate 30 is flush with the outer peripheral surface of the mounting frame 20, which avoids the formation of concave-convex structures between the rotating plate 30 and the mounting frame 20 after installation, and facilitates stacking and storage or transportation of a plurality of second mounting frames 20 corresponding to the mounting frame 20.

[0039] The above description is only preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made according to the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
