[0045] At present, there are not many testing methods for bushings in test workshops or other use scenarios that need to collect bushing wear resistance data during APC flipping. Most of them use simple components for testing, or directly test on APC equipment. However, the installation and removal of bushings in APC equipment are complicated, which is not conducive to testing. The test results of some bushing test components on bushings are very different from the results of actual application of bushings, the test results are inaccurate and unreliable, and the test cycle is relatively long.

[0046] The core of this application is to provide a testing device for a flexible bushing, which can make the test results stable and reliable and the test efficiency high.

[0047] For details of the specific embodiment 1 of the testing device for the flexible bushing provided in this application, please refer to Figure 1 , including a frame 1, a beam 2, a clamping component 3, an impact component 5 and a fixing component 4.

[0048] Among them, the beam 2 is arranged in the frame 1 and can slide along the first direction, the clamping assembly 3 is arranged at one end of the beam 2, and the clamping assembly 3 defines an installation cavity for installing the bushing 100 to be tested, and the installation cavity is located on the side of the clamping assembly 3 away from the beam 2; the fixing assembly 4 is used to fix the bushing 100 to be tested in the installation cavity; the impact assembly 5 is arranged on the frame 1, which is located on the side of the clamping assembly 3 away from the beam 2, and the impact assembly 5 is used to impact the fixing assembly 4 to test the bushing 100 to be tested.

[0049] The impact assembly 5 includes a rotating shaft 501 , a bearing 502 is sleeved on the rotating shaft 501 ; a disc 503 is sleeved on the bearing 502 , and collision teeth 504 are arranged at circumferential intervals on the disc 503 , wherein the rotating shaft 501 drives the disc 503 to rotate through the bearing 502 .

[0050] Specifically, the rotating shaft 501 can be any one of the driving devices such as an electric motor, an engine, a gear transmission, a hydraulic transmission, etc. The impact component 5 can be a circular toothed block. The rotating shaft 501 can be connected to the center of the circle of the impact component 5 through the axis. When the rotating shaft 501 rotates, the impact component 5 can rotate around the rotating shaft 501. It should be noted that the rotation direction is not limited here. Thus, the testing device for the flexible bushing provided by the present application includes a frame 1, a crossbeam 2, an impact assembly 5, a clamping assembly 3 and a rotating shaft 501, wherein the crossbeam 2 is installed in the frame 1, and the clamping assembly 3 is connected to the frame 1 through the crossbeam 2; an installation cavity for installing the bushing 100 to be tested is defined in the clamping assembly 3, and the bushing 100 to be tested can be fixed in the clamping assembly 33 to avoid the bushing moving and causing inaccurate test results; the rotating shaft 501 is connected to the impact assembly 5, and the installation cavity is located on the side of the clamping assembly 33 close to the impact assembly 54. When the rotating shaft 501 drives the impact assembly 54 to rotate around the rotating shaft 501, the impact assembly 54 is squeezed with the bushing 100 to be tested through the clamping assembly 33, which can simulate the use scenario of the bushing during the APC flipping process, which is closer to the actual working condition of the bushing wear, thereby further improving the accuracy of the test.

[0051] In some preferred embodiments, the center of the disk 503 is located on the extension line of the transverse beam 2 along the first direction. This arrangement enables the clamping assembly 3 and the impact assembly 5 to be located at the same level, and the impact assembly 5 can make the test result of the tested bushing 100 more accurate and controllable during the test.

[0052] It can be understood that the first direction is Figure 1 The middle X direction, the second direction is Figure 1 The middle Y direction, the third direction is Figure 1 Middle Z direction.

[0053] In some other embodiments of the present application, the connection method between the clamping assembly 3 and the frame 1 through the crossbeam 2 can be as follows: Figure 1As shown, the clamping assembly 3 of the testing device for the flexible bushing provided in the present application may include a pad 301 connected to one end of the beam 2, at least one mounting seat 302, the mounting seat 302 is arranged on a side of the pad 301 away from the beam 2, the mounting cavity passes through the mounting seat 302 along the second direction, and the mounting seat 302 is provided with a groove 304 for the impact assembly 5 to pass along the third direction. For example, it can be a mounting method such as welding, riveting or bolting, so that the clamping assembly 3 is fixed on the beam 2 to avoid unstable installation of the clamping assembly 3 and affect the accuracy of the test result, wherein the connection relationship between the pad 301 and the beam 2, and the connection relationship between the mounting seat 302 and the pad 301 may be the same or different, and there is no limitation here. It can be understood that a groove 304 for the impact assembly 5 to pass is provided on the mounting seat 302 along the first direction, and its function is to ensure that the impact assembly 5 can accurately test the bushing 100 to be tested in the mounting cavity of the mounting seat 302 when testing.

[0054] In some other embodiments of the present application, Figure 2 As shown, the mounting seat 302 includes first mounting ears 303 that are symmetrical along the transmission shaft 501, and grooves 304 are formed between the first mounting ears 303, wherein the first mounting ears 303 are each provided with a penetrating mounting cavity. It can be understood that the provision of the first mounting ears 303 can facilitate the clamping and fixing of the bushing. On the other hand, the first mounting ears 303 can also save materials and reduce the weight of the entire test device.

[0055] In addition, by using the flexible bushing testing device of the present invention, the wear resistance test data of multiple bushings can be obtained by replacing the bushing 100 to be tested located in the clamping assembly 33, avoiding direct testing of the bushing in the APC. The testing method is simpler and the testing efficiency is greatly improved.

[0056] In some other embodiments of this application, please continue to refer to Figure 2 as well as Figure 3 The fixing component 4 includes a connecting piece 401, and a connecting piece 401 is arranged on the side of the first mounting ear 303 away from the groove 304, and one end of the connecting piece 401 is rotatably connected to the first mounting ear 303; a connecting shaft 402 is arranged in the mounting cavity, and is used to connect the other ends of the two connecting pieces 401; a chain roller 403 is sleeved on the connecting shaft 402, and is used to transmit the impact force of the impact component 5 to the bushing 100 to be tested, and the chain roller 403 at least partially extends into the groove 304.

[0057] Specifically, the two connecting plates 401 are connected by a connecting shaft 402, and the chain roller 403 is sleeved on the connecting shaft 402. It can be understood that the chain roller 403 is also sleeved with a bushing 100 to be tested. When the bushing 100 to be tested needs to be tested, the clamping assembly 3 is moved to a reasonable position through the crossbeam 2, and the impact assembly 5 is started to rotate at high speed. The collision teeth 504 on the disc 503 collide with the part of the chain roller 403 extending to the groove 304, so that the chain roller 403 converts the collision force into an extrusion force on the bushing 100 to be tested, so as to successfully complete the test work.

[0058] In some other embodiments of the present application, the distance between the axis of the impact assembly 5 and the axis of the chain roller 403 is A, the radius of the tooth top circle of the disk 503 is B, the radius of the chain roller 403 is C, and A<B+C.

[0059] Specifically, the sum of the radius of the impact assembly 5 and the radius of the chain roller 403 is slightly greater than the distance between the two axes. Preferably, the distance can be the compression amount generated by the tested bushing 100 being squeezed when the tested bushing 100 is hit by the flipping tooth 504 during the rotation process.

[0060] In this way, by making the sum of the radius of the impact assembly 5 and the radius of the chain roller 403 slightly larger than the distance between the two axes, a space is reserved for when the bushing is squeezed, thereby ensuring the safety and stability of the test device.

[0061] In some other embodiments of this application, please refer to Figure 2 The mounting seat 302 is also provided with a second mounting ear 305, and the second mounting ear 305 and the first mounting ear 303 are spaced apart along the third direction and symmetrically arranged with the beam 2 as the symmetry axis, and the aperture of the mounting cavity of the second mounting ear 305 is different from the aperture of the mounting cavity of the first mounting ear 303.

[0062] Specifically, the second mounting ear 305 can be correspondingly arranged below the first mounting ear 303. When multiple bushings need to be tested simultaneously, a bushing 100 of a different type from the bushing 100 to be tested in the first mounting ear 303 can be installed in the second mounting ear 305, thereby improving the applicability of the flexible bushing test device provided by the present application, and being able to test multiple bushings 100 of different types to be tested simultaneously, greatly improving the efficiency of the test. It is worth noting that the number of mounting ears in this solution can be an even number.

[0063] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
