[0066] Embodiment 1

[0067] With the improvement of machining technology, the clutch 700 is increasingly widely used in various fields of instruments and equipment. The clutch 700 is a commonly used component in mechanical transmission and can separate or engage the transmission system at any time. Its basic requirements are: smooth engagement, quick and complete separation; convenient adjustment and repair; small overall dimensions; small mass; good wear resistance and sufficient heat dissipation capacity; convenient and labor-saving operation, and it is commonly divided into two categories: jaw type and friction type. In order to ensure the stable operation of the clutch 700, the test of the clutch 700 is an essential step.

[0068] This embodiment provides a fixture, which fixes the clutch 700 through the fixture and installs it on the driving member, and uses the driving member to drive the fixture loaded with the clutch 700 to rotate at high speed, and then conducts a durability test on the clutch 700 so that the clutch 700 meets the service performance.

[0069] Such as Figure 1 and Figure 2As shown, as an alternative, the fixture includes a driving shaft 100, a driven shaft 200, a mounting shaft 300, a first fixing component 400, and a second fixing component 500. The driving shaft 100 is connected to a driving member. The driven shaft 200 is coaxially arranged with the driving shaft 100. The mounting shaft 300 includes multiple models, and each model of the mounting shaft 300 corresponds to a different model of the clutch 700 to be tested one by one. The mounting shaft 300 is selectively and detachably arranged between the driving shaft 100 and the driven shaft 200. The clutch 700 to be tested is sleeved on the mounting shaft 300. Thus, by replacing the corresponding mounting shaft 300, the fixture can be applied to different models of the clutch 700, expanding the applicable range of the fixture. When the first fixing component 400 is in the first position, the first fixing component 400 can fix the relative positions of the mounting shaft 300 and the driving shaft 100. When the first fixing component 400 is in the second position, the mounting shaft 300 can be detached from the driving shaft 100. When the second fixing component 500 is in the third position, the second fixing component 500 can fix the relative positions of the mounting shaft 300 and the driven shaft 200. When the second fixing component 500 is in the fourth position, the mounting shaft 300 can be detached from the driven shaft 200. When the first fixing component 400 is in the first position and the second fixing component 500 is in the third position, the clutch 700 is fixed on the mounting shaft 300, and the mounting shaft 300 can rotate at a high speed driven by the driving shaft 100 and the driven shaft 200, so as to facilitate the detection of the clutch 700. By adjusting the switching of the first fixing component 400 between the first position and the second position, and the switching of the second fixing component 500 between the third position and the fourth position, the mounting shaft 300 is detachably connected, and the assembly and disassembly of the mounting shaft 300 are convenient, which is beneficial to reducing the changeover time and improving the changeover efficiency. At the same time, by making the mounting shaft 300 applicable to different specifications of the clutch 700 and then installing the mounting shaft 300 between the driving shaft 100 and the driven shaft 200, the fixture can be applied to different specifications of the clutch 700, improving the compatibility of the fixture, and facilitating the quick disassembly and assembly of the clutch 700, thus improving the working efficiency.

[0070] Please continue to refer to Figure 1 and Figure 2, during operation, the first fixing component 400 is sleeved on the driving shaft 100 and located at the second position, the second fixing component 500 is sleeved on the driven shaft 200 and located at the fourth position. Meanwhile, the clutch 700 is sleeved on the mounting shaft 300, and the mounting shaft 300 is arranged between the driving shaft 100 and the driven shaft 200. Then, by adjusting the first fixing component 400 to the first position to fix the relative position between the mounting shaft 300 and the driving shaft 100, and adjusting the second fixing member 520 to the third position to fix the relative position between the driven shaft 200 and the mounting shaft 300, the clutch 700 is fixed therein. This fixture is convenient for disassembly, assembly and model change, has strong adaptability, is beneficial to improving the test efficiency of the clutch 700, and reduces the fixture cost.

[0071] This embodiment also provides a clutch test device. With the above-mentioned fixture, it is beneficial to reduce costs, improve the adaptability and compatibility of the clutch test device, and improve the detection efficiency.

[0072] Now in combination with Figures 1 to 4 the detailed structure of the driving shaft 100 will be described. As Figures 1 to 3 shown, the driving shaft 100 includes a first mounting portion 110, and the first mounting portion 110 is connected to the driving member of the clutch test device. The driving member drives the driving shaft 100 to rotate, thereby driving the fixture to rotate. It can be understood that, as Figure 4 shown, the fixture includes a bearing seat 600, which is sleeved on the first mounting portion 110 to improve the service life of the driving shaft 100. Meanwhile, the driving shaft 100 further includes a first mounting portion 110, and a first keyway 111 is formed on the first mounting portion 110. By connecting with the first fixing component 400 through the first keyway 111, the driving shaft 100 can be connected and fixed to the first fixing component 400. It can be understood that when the driving shaft 100 is connected to the first fixing component 400, the first fixing component 400 is located at the first position, and this first position can restrict the rotational freedom of the first fixing component 400 relative to the driving shaft 100 and the mounting shaft 300.

[0073] As Figures 1 to 3 shown, the driving shaft 100 further includes a first limiting boss 120, and the first limiting boss 120 is annularly arranged on the driving shaft 100. Specifically, the first limiting boss 120 is annularly arranged at one end of the first connecting portion 130 away from the mounting shaft 300. By the first limiting boss 120, the farthest distance of the first fixing component 400 in the direction away from the mounting shaft 300 is restricted, playing a limiting role on the first fixing component 400. When the first fixing component 400 is located at the second position, the side of the first fixing component 400 away from the mounting shaft 300 can abut against the first limiting boss 120 to restrict the farthest distance of the first fixing component 400 away from the mounting shaft 300.

[0074] Now in combination with Figure 1 、Figure 2 , Figures 5 to 8 As shown, the detailed structure of the mounting shaft 300 will be described.

[0075] As Figure 1 , Figure 2 , Figures 5 to 8 As shown, the mounting shaft 300 includes a first end 310 and a second end 320. The clutch 700 can be sleeved on the first end 310. The outer diameter of the clutch 700 is the same as the corresponding inner diameter of the second fixing component 500. The second end 320 is connected to the driving shaft 100, and the outer diameter of the second end 320 is the same as the corresponding inner diameter of the first fixing component 400. Thus, the mounting shaft 300 serves as a tooling for loading clutches 700 of different specifications. Regardless of the model of the mounting shaft 300, after loading the corresponding model of the clutch 700, the outer dimensions are fixed dimensions, and these fixed dimensions are consistent with the mating dimensions of the driving shaft 100, the driven shaft 200, the first fixing component 400, and the second fixing component 500, so as to facilitate the use of the fixture for testing clutches 700 of different models.

[0076] As Figure 1 , Figure 2 , Figures 5 to 8 As shown, the structures and dimensions of the second ends 320 of the mounting shaft 300 are the same, so that the second ends 320 can be fitted and connected to the driving shaft 100 and the first fixing component 400. The diameter and other dimensions of the first end 310 of the mounting shaft 300 change according to the dimensions of the clutch 700, so that the first end 310 can load clutches 700 of different dimensions. As Figure 5 ~ shown in FIGS. 8, specifically, the lengths, inner diameters, outer diameters, etc. of clutches 700 of different models are all different. In order to keep the same outer dimensions after assembling different models of mounting shafts 300 with different models of clutches 700, the first end 310 is divided into a loading part 311 and an adjusting part 312. Among them, the loading part 311 is used to sleeve the clutch 700. Therefore, the outer diameter and the length in the axial direction of the loading part 311 are consistent with the inner diameter of the clutch 700, so that it can be connected to the corresponding model of the clutch 700. The outer diameter of the adjusting part 312 is adjusted according to the inner diameter of the corresponding position of the second fixing component 500. The length of the adjusting part 312 in the axial direction is adjusted according to the length of the clutch 700, that is, the total length of the loading part 311 and the adjusting part 312 remains stable. When the length of the adjusting part 312 is always the difference between the total length and the length of the clutch 700, the total length of the second end 320 remains unchanged.

[0077] Optionally, the mounting shaft 300 further includes a second limiting boss 330, which is arranged between the first end 310 and the second end 320 to restrict the extreme position of the first fixing component 400 moving along the axial direction of the second end 320, playing a role in limiting the first fixing component 400.

[0078] Now, in combination with Figure 1 , Figure 2 , Figure 9 and Figure 10 the detailed structure of the first fixing component 400 will be described.

[0079] As shown in Figure 1 , Figure 2 Figure 9 , the first fixing component 400 includes a first connecting member 410. The first connecting member 410 is used to connect the mounting shaft 300 and the driving shaft 100, so that the rotation of the driving shaft 100 can drive the mounting shaft 300 to rotate accordingly.

[0080] Please continue to refer to Figure 1 , Figure 2 and Figure 9 . As an alternative solution, the first connecting member 410 is sleeved on the outer periphery of the first mounting portion 110 and the mounting shaft 300. And in the axial direction of the driving shaft 100, the first connecting member 410 can slide relative to the driving shaft 100, that is, the first connecting member 410 can slide between a first position and a second position, so as to facilitate the switching of the first connecting member 410 between the first position and the second position. And by switching the position of the first connecting member 410, it is possible to facilitate the assembly and disassembly of the mounting shaft 300, reduce the changeover time, and improve the changeover efficiency.

[0081] Please continue to refer to Figure 1 , Figure 2 and Figure 9 . A second key groove 321 is formed on the mounting shaft 300, and a third key groove 411 is formed on the first connecting member 410. The first fixing component 400 further includes a connecting key. The connecting key is arranged in the first key groove 111, the second key groove 321 and the third key groove 411 to connect the first mounting portion 110, the mounting shaft 300 and the first connecting member 410. And the connecting key can slide in the third key groove 411. The connecting key can both restrict the rotational freedom of the rotating shaft and the first connecting member 410 relative to the first mounting portion 110, and enable the first connecting member 410 to slide and switch between the first position and the second position. The structure is simple and easy to operate.

[0082] Please continue to refer to Figure 1 , Figure 2 and Figure 9, specifically, the second keyway 321 extends along the axial direction of the mounting shaft 300 and is formed on the second end 320. The side of the second keyway 321 away from the first end 310 is in an open state. The second keyway 321 extends along the axial direction of the driving shaft 100 and is provided on the first mounting portion 110. The end of the second keyway 321 away from the first limiting boss 120 is in an open state, so that the first keyway 111 and the second keyway 321 can be docked through a connecting key. The third keyway 411 extends along the axial direction of the first connecting member 410 and is provided on the inner wall of the first connecting member 410. The third keyway 411 is a through slot at both ends of the first connecting member 410, so that the first connecting member 410 can slide along the axial direction of the driving shaft 100.

[0083] As Figure 1 , Figure 2 and Figure 10 shown, further, the first fixing assembly 400 further includes a first fixing member 420 sleeved on the driving shaft 100. The first fixing member 420 is located between the first connecting member 410 and the first limiting boss 120, so that the first connecting member 410 is located between the first fixing member 420 and the second limiting boss 330, thereby preventing the first connecting member 410 from sliding during the rotation of the driving shaft 100 and improving the safety and stability of the fixture.

[0084] As Figure 1 , Figure 2 and Figure 10 shown, the first fixing member 420 includes a first half-ring 421 and a second half-ring 422. The first half-ring 421 and the second half-ring 422 can be cooperatively sleeved on the first mounting portion 110. The first half-ring 421 and the second half-ring 422 are fixed by screws, so that the first fixing member 420 is integrally fixed on the first mounting portion 110. The first fixing member 420 can restrict the freedom degree of the first connecting member 410 to slide along the axial direction of the driving shaft 100, so that the first connecting member 410 is located between the second limiting ring and the first fixing member 420.

[0085] Now in combination with Figures 1 to 10The installation and disassembly process of the driving shaft 100, the installation shaft 300 and the first fixing assembly 400 is described. When working, the driving shaft 100 is first loaded on the driving member, and then the first connecting member 410 is sleeved on the driving shaft 100. The connecting key is placed in the first keyway 111 and the third keyway 411. After the first end 310 of the installation shaft 300 is loaded with the clutch 700, the second keyway 321 of the second end 320 is opposite to the first keyway 111 of the first mounting portion 110, and then the first connecting member 410 slides along the axis of the driving shaft 100 toward the second end 320. When the first connecting member 410 reaches the first position, that is, the limit position where the first connecting member 410 can move, the first half ring 421 and the second half ring 422 are sleeved on the first mounting portion 110, and the first half ring 421 and the second half ring 422 are arranged on the side of the first connecting member 410 away from the second end 320, and the first half ring 421 and the second half ring 422 are fixed by screws. To disassemble, perform the above process in reverse.

[0086] When a clutch 700 of a different model needs to be tested, only the mounting shaft 300 and the corresponding clutch 700 need to be replaced, and then loaded onto the driving shaft 100 , the driven shaft 200 , the first fixing assembly 400 and the second fixing assembly 500 again.

[0087] Now combined Figure 1 , Figure 2 and Figure 11 The detailed structure of the driven shaft 200 will be described.

[0088] like Figure 1 , Figure 2 and Figure 11 As shown, the driven shaft 200 includes a second connecting portion 220, which can be connected to the coaxial device or the bearing seat 600, and its function is to support the clamp as a whole together with the first connecting portion 130, so that the clamp can rotate under the drive of the driving member. The driven shaft 200 also includes a second mounting portion 210, and the end surface of the second mounting portion 210 abuts against the end surface of the first end 310 away from the second end 320.

[0089] Now combined Figure 1 , Figure 2 and Figure 12 The detailed structure of the second fixing assembly 500 is described.

[0090] like Figure 1 , Figure 2 and Figure 12As shown, the second fixing component 500 includes a second connecting member 510. The second connecting member 510 is used to connect the mounting shaft 300 and the driven shaft 200. Through the second connecting member 510, the first end 310 can be connected to the driven shaft 200, and at the same time, the relative rotational freedom between the first end 310 and the driven shaft 200 is restricted, so that after the driving shaft 100, the driven shaft 200 and the mounting shaft 300 are assembled and fixed, they can be coaxial and rotate together.

[0091] As Figure 1 , Figure 2 and Figure 12 shown, the second connecting member 510 is sleeved on the outer circumferences of the clutch 700 and the driven shaft 200, and along the axial direction of the driven shaft 200, the second connecting member 510 can slide relative to the driven shaft 200, so that the second connecting member 510 can be switched between a third position and a fourth position to facilitate the quick installation and fixation of the mounting shaft 300.

[0092] As Figure 1 , Figure 2 and Figure 12 shown, the second connecting member 510 includes a third connecting portion 511 and a limiting portion 512. Among them, the inner diameter of the part of the limiting portion 512 sleeved on the outer diameter of the first end 310 is set according to the outer diameter of the first end 310 after the clutch 700 is sleeved, that is, when testing clutches 700 of different models, the second connecting member 510 is correspondingly replaced with the corresponding model. Splines are provided on the inner diameter of the second connecting portion 220, and splines are also provided on the outer diameter of the end of the third connecting portion 511 close to the mounting shaft 300. The third connecting portion 511 and the second mounting portion 210 are in spline fit, thereby restricting the relative rotational freedom between the third connecting portion 511 and the second mounting portion 210, and enabling the third connecting portion 511 to slide relative to the second mounting portion 210 along the axial direction.

[0093] Please continue to refer to Figure 1 , Figure 2 , the second fixing component 500 further includes a second fixing member 520 provided on the driven shaft 200. The second fixing member 520 can fix the position of the second connecting member 510 relative to the driven shaft 200, avoiding the automatic sliding of the second connecting member 510, resulting in the detachment of the mounting shaft 300, which is beneficial to improving the safety of the fixture.

[0094] Now in combination with Figure 1 , Figure 2The assembly and disassembly processes of the driven shaft 200, the mounting shaft 300, and the second fixing assembly 500 will be described. During installation, first, the second connecting member 510 is sleeved on the second mounting portion 210 and slid to one end away from the mounting shaft 300. Then, the mounting shaft 300 loaded with the clutch 700 is disposed between the driving shaft 100 and the driven shaft 200, and the first end 310 abuts against one end of the second mounting portion 210 away from the second connecting portion 220. Next, the second connecting member 510 is slid so that it is sleeved on the outer periphery of the first end 310 and the second mounting portion 210. Finally, it is fixed to the second mounting portion 210 with the second fixing member 520, and specifically fixed on the side of the second connecting member 510 away from the first end 310, thereby restricting the displacement of the second connecting member 510 in the axial direction. It can be understood that after the test is completed, the disassembly process is opposite to the above assembly process. During tool change, the model of the second connecting member 510 is selected corresponding to the mounting shaft 300.

[0095] Embodiment 2

[0096] This embodiment provides a clutch testing method. The assembly steps of the clutch 700 before testing are as follows through the above fixture:

[0097] The first fixing assembly 400 is sleeved on the driving shaft 100 and located at the second position, and the second fixing assembly 500 is sleeved on the driven shaft 200 and located at the fourth position;

[0098] The clutch 700 is sleeved on the mounting shaft 300;

[0099] Slide the first fixing assembly 400 to the first position to connect and fix the mounting shaft 300 to the driving shaft 100;

[0100] Slide the second fixing assembly 500 to the third position to connect and fix the mounting shaft 300 to the driven shaft 200; and

[0101] The driving member drives the whole fixture to rotate for testing.

[0102] The fixture can be detachably connected by adjusting the switching of the first fixing assembly 400 between the first position and the second position, and the switching of the second fixing assembly 500 between the third position and the fourth position. The mounting shaft 300 is convenient for assembly and disassembly, which is beneficial to reducing the tool change time and improving the tool change efficiency. At the same time, the mounting shaft 300 is applicable to clutches 700 of different specifications. Then, the mounting shaft 300 is installed between the driving shaft 100 and the driven shaft 200, so that the fixture can be applicable to clutches 700 of different specifications, improving the compatibility of the fixture and facilitating the quick disassembly and assembly of the clutch 700, thus improving the working efficiency.

[0103] Furthermore, when detecting clutches 700 of different models, the clutch 700 is installed on the corresponding mounting shaft 300 and assembled with the driving shaft 100, the driven shaft 200, the first fixing assembly 400, and the second fixing assembly 500. The mounting shaft 300 is applicable to clutches 700 of different specifications. Then, the mounting shaft 300 is installed between the driving shaft 100 and the driven shaft 200, enabling the fixture to be applicable to clutches 700 of different specifications, improving the compatibility of the fixture, facilitating the quick disassembly and assembly of the clutch 700, and enhancing the working efficiency.

[0104] Now, in combination with Figures 1 to 12 describe the working process of the fixture.

[0105] During assembly, first, the driving shaft 100 is loaded on the driving member. Then, the first connecting member 410 is sleeved on the driving shaft 100 and located at the second position. The connecting key is placed in the first keyway 111 and the third keyway 411. At the same time, the second connecting member 510 is sleeved on the second mounting portion 210 and slides to one end away from the mounting shaft 300. Then, the mounting shaft 300 loaded with the clutch 700 is arranged between the driving shaft 100 and the driven shaft 200, and the first end 310 abuts against one end of the second mounting portion 210 away from the second connecting portion 220, and the end face of the second end 320 abuts against one end of the first mounting portion 110 away from the first connecting portion 130, making the second keyway 321 of the second end 320 opposite to the first keyway 111 of the first mounting portion 110. Then, the first connecting member 410 slides along the axis of the driving shaft 100 towards the second end 320. When the first connecting member 410 reaches the first position, that is, the limit position where the first connecting member 410 can move, the first half-ring 421 and the second half-ring 422 are sleeved on the first mounting portion 110, and the first half-ring 421 and the second half-ring 422 are arranged on the side of the first connecting member 410 away from the second end 320, and the first half-ring 421 and the second half-ring 422 are fixed by screws. Then, the second connecting member 510 is slid to sleeve on the outer periphery of the first end 310 and the second mounting portion 210. Finally, it is fixed to the second mounting portion 210 with the second fixing member 520, specifically fixed on the side of the second connecting member 510 away from the first end 310, thereby restricting the displacement of the second connecting member 510 in the axial direction.

[0106] After the test is completed, the disassembly process is the reverse of the above process. When changing the model, only the clutch 700 of the corresponding model needs to be installed on the corresponding mounting shaft 300, and then the second connecting member 510 of the corresponding model is replaced, and the remaining operation steps are the same as above.
