[0040] 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 mechanisms 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 testing institutions are very different from the actual application results of bushings, the test results are inaccurate and unreliable, and the test cycle is relatively long.

[0041] The core of the utility model is to provide a testing device for a flexible bushing, which can make the testing result stable and reliable and the testing efficiency high.

[0042] For a specific example of the testing device for the flexible bushing provided by the present utility model, please refer to Figure 1 to Figure 2 , comprising a frame 1, a flexible bushing test unit 2 is installed in the frame 1; and a crossbeam 3, used to connect the frame 1 and the flexible bushing test unit 2. Specifically, the flexible bushing test unit 2 is slidably connected to the crossbeam 3 so as to be able to move along a first direction. Preferably, the first direction may be a horizontal direction.

[0043] like Figure 2As shown, in this embodiment, the flexible bushing test unit 2 includes a drive assembly, wherein the drive assembly serves as a power source to drive the tray 24 to reciprocate along the first direction. Specifically, the drive member 21 in the drive assembly can be any one of drive devices such as an electric motor, an engine, a gear transmission, a hydraulic transmission, etc., for example, it can be a cylinder.

[0044] The flexible bushing test unit 2 further includes a pallet 24, which can be used for packaging, stacking, handling and transportation, and serves as a horizontal platform device for unit load goods and products. Specifically, the pallet 24 serves as a load carrier, and is used to load the clamping mechanism 27, so that the driving member 21 can drive the clamping mechanism to reciprocate along the first direction.

[0045] The flexible bushing test unit 2 further includes a clamping mechanism 27 defining a mounting cavity for fixing the bushing. Specifically, the clamping mechanism 27 can be mounted on one end of the axis of the tray 24 .

[0046] The flexible bushing test unit 2 further includes an impact component 28, which may be a component used to simulate the wear caused by friction with the bushing in actual working conditions, such as a conveyor turning tooth, etc. As an example, the impact component 28 may be a toothed block.

[0047] In this embodiment, the driving assembly serves as a power source to drive the tray 24 to reciprocate along the first direction through the beam 3. The clamping mechanism 27 located on the tray 24 drives the bushing to reciprocate synchronously, generating friction with the impact component 28, thereby simulating the friction with the bushing in actual working conditions and causing wear of the bushing.

[0048] The test device for the flexible bushing provided by the utility model comprises a frame, a crossbeam and a flexible bushing test unit, the flexible bushing test unit comprises a clamping mechanism, a tray, at least one impact component and a driving assembly, wherein the crossbeam is installed in the frame, and the flexible bushing test unit is connected to the frame through the crossbeam so that the flexible bushing test unit can move along a first direction; an installation cavity for installing the bushing is defined in the clamping mechanism, and the bushing can be fixed in the flexible bushing test device to avoid the situation where the bushing moves and produces inaccurate test results; the driving assembly is used to drive the tray to drive the clamping mechanism to move along the first direction, and when the clamping mechanism moves to the impact component, the impact component contacts the bushing, 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.

[0049] In addition, by using the flexible bushing test device of the present solution, the wear resistance test data of multiple bushings can be obtained by replacing the bushings in the clamping device, avoiding directly testing the bushings in the APC. The test method is simpler and the test efficiency is greatly improved. In some embodiments, the flexible bushing test unit 2 also includes a push rod 22 and a push rod fixing plate 23. The push rod 22 is used to connect the drive member 21 and the tray 24 so that the drive member 21 pushes the tray 24. The push rod fixing plate 23 is used to connect the push rod 22 and the tray 24; further, in order to better fix the push rod 22 and the tray 24, the push rod fixing plate 23 can be installed at the other end of the central axis of the tray 24.

[0050] In this way, this embodiment can improve the stability of the driving assembly pushing the tray 24 by setting a push rod 22, connecting the driving member 21 and the tray 24, thereby improving the test efficiency of the flexible bushing; further, the push rod fixing plate 23 is used to connect the push rod 22 and the tray 24, which further fixes the tray 24 compared to the push rod 22 directly connecting 24, so that the tray 24 is more stable when reciprocating along the first direction, thereby further improving the test efficiency of the flexible bushing. In some embodiments, the flexible bushing test unit 2 also includes a mounting plate 25, which is used to fix the driving assembly and the impact component 28, which can be a grid plate with a certain length, and the tray 24 is installed on the crossbeam 3 on the frame 1 through the mounting plate 25. In addition, the driving assembly and the impact component 28 are installed on the mounting plate 25.

[0051] In this way, the present embodiment installs the flexible bushing test unit 2 on the crossbeam 3 on the frame 1 by setting the mounting plate 25, so as to facilitate the sliding of the tray 24 on the crossbeam 3 along the first direction to improve the test efficiency of the flexible bushing. In addition, the drive assembly and the impact component 28 are installed and set at a fixed position on the mounting plate 25, which can improve the stability of the flexible bushing test device and reduce the displacement caused by the friction of the drive assembly on the impact component, thereby improving the accuracy of the flexible bushing test results. Furthermore, in order to further improve the accuracy of the flexible bushing test results, the flexible bushing test unit 2 also includes a drive member connection block 26. The drive member 21 can be fixed to the mounting plate 25 through the drive member connection block 26.

[0052] In some embodiments, the number of the impact component 28 is at least one. When the number of the impact components 28 is two, they are respectively mounted at the front and rear ends of the mounting plate 25; when the number of the impact components 28 is multiple, they are respectively arranged and mounted at both ends of the mounting plate 25. It should be noted that in order to meet the testing requirements of various flexible bushings, in some embodiments, the connection between the impact component 28 and the mounting plate 25 can be integrally formed or detachably connected. As an example, when the impact component 28 needs to be replaced or maintained regularly, the connection between the impact component 28 and the mounting plate 25 can be detachably connected, so as to facilitate the replacement or maintenance of the impact component 28.

[0053] Please see Figure 3 In this embodiment, the clamping mechanism 27 may include a bushing mounting seat 271, a chain link 272, a chain link buckle 273, and a chain link roller 274. The chain link buckle 273 is used to fix the bushing, and the chain link roller 274 is provided on the chain link 272 locked by the chain link buckle 273. The bushing 275 is installed in the round hole of the bushing mounting seat 271, and the pin on the chain link buckle 273 passes through the round hole in the bushing 275, and the chain link roller 274 is fixed between the bushings 275. The chain link buckle 273 is installed on the bushing mounting seat 271, so that the bushing 275 is installed in the flexible bushing test device.

[0054] In some embodiments, the number of bushings 275 can be set according to actual conditions. For example, the number of bushings can be set to multiple under the condition that the impact component 28 has sufficient contact area with the bushing 275. In this way, by setting the number of bushings, the number of bushings to be tested can be flexibly adjusted according to the test requirements of the flexible bushing, which can further improve the test efficiency of the flexible bushing.

[0055] Furthermore, in this embodiment, the driving member 21 horizontally pushes the counterweighted tray 24 to move in the first direction, and the chain roller 274 located on the clamping mechanism 27 hits the impact component 28 located on the mounting plate 25. The chain roller 274 squeezes the bushing 275 through the chain buckle 273 passing through the bushing 275, thereby causing wear to the bushing.

[0056] Thus, by arranging the bushing mounting seat 271 and the chain unit in the clamping mechanism 27. The chain unit may include a chain link 272 and a chain link buckle 273, the chain link roller 274 is fixed between the bushings 275, and the chain link buckle 273 is installed on the bushing mounting seat 271, so that the bushing 275 to be tested can be well limited, and the bushing displacement during the test process can be avoided to cause inaccurate test results, thereby improving the accuracy of the test results of the flexible bushing.

[0057] Please see Figure 4In some embodiments, the mounting plate may specifically include a push rod slot 231, a pin hole 232, and a bolt hole 233. The push rod slot 21 is used to position the push rod 22 so that the push rod 22 can move along the first direction. Specifically, the tray 24 is provided with a pin hole and a nut, and the push rod slot 231 is positioned with the pin hole 232 and the pin hole on the tray 24. In addition, the push rod slot 231 is provided with four bolt holes 233, and the bolts pass through the bolt holes 233 and are locked with the nuts on the tray 24 to fix them.

[0058] Thus, by providing the push rod slot 231 , the pin hole 232 and the bolt hole 233 , the push rod 22 and the tray 24 can be further fixed, thereby improving the stability of the testing device of the flexible bushing and thus improving the accuracy of the testing result of the flexible bushing.

[0059] Further, the shape of the push rod slot 231 is not limited. The shape of the push rod slot 231 includes but is not limited to a T-shaped slot or a U-shaped slot, etc., which can be set according to the shape of the push rod 22, so as to facilitate the push rod 22 to move along the first direction. The push rod slot 231 and the push rod 22 are both set on the mounting plate 23, and the connection method thereof includes but is not limited to a buckle connection.

[0060] Furthermore, the front end of the push rod 22 is installed in the push rod slot 231, and a gap of a certain length is set between the push rod 22 and the push rod slot 231. Specifically, the width of the push rod slot can be set to be slightly smaller than the diameter of the push rod 22, so that the push rod 22 has a certain amount of space floating in the push rod slot 231, thereby reducing the driving resistance caused by position deviation when the driving member 21 drives the push rod 22.

[0061] In this way, by setting a gap of a certain length between the push rod 22 and the push rod slot 231 and reserving a certain space, the driving resistance caused by position deviation when the driving member 21 drives the push rod 22 can be reduced, thereby improving the accuracy of the flexible bushing test result.

[0063] In addition, by using the flexible bushing test device of the present invention, the wear resistance test data of multiple bushings can be obtained by replacing the bushings in the clamping device, avoiding direct testing of the bushings in the APC. The test method is simpler and the test efficiency is greatly improved.
