[0035] In this embodiment, as Figure 1 and Figure 2 shown, a sealing brush wear test bench includes a test bench body 1, a power assembly 2 is installed on the test bench body 1, the power assembly 2 drives the test bench body 1 to move, the power assembly 2 includes a bearing bracket 21, a slide rail 22, a first driving member 23 and a second driving member 24, the bearing bracket 21 is installed at the bottom of the test bench body 1, the slide rail 22 is slidably connected in the chute of the test bench body 1, the slide rail 22 and the bearing bracket 21 are fixedly connected, the first driving member 23 drives the test bench body 1 to reciprocate along the slide rail 22, and the second driving member 24 drives the bearing bracket 21 and the test bench body 1 to rotate together.

[0036] Thus, when testing the strip-shaped sealing brush, the first driving member 23 is used to drive the test bench body 1 to reciprocate for testing. When testing the annular sealing brush, the second driving member 24 is used to drive the bearing bracket 21 and the test bench body 1 to rotate. The two different movement methods are convenient for conducting wear experiments on sealing brushes of different shapes.

[0037] Furthermore, there are two slide rails 22, and two corresponding chutes are opened at the bottom of the test bench body 1. The bearing bracket 21 is used to install the test bench body 1. When testing the strip-shaped sealing brush, the first driving member 23 drives the sealing brush in the test bench body 1 to reciprocate, and the second driving member 24 drives the bearing bracket 21 to rotate to complete the wear experiment on the annular sealing brush.

[0038] In some embodiments, as Figure 1 and Figure 3 shown, the first driving member 23 includes a transmission shaft 231, a runner 232, a connecting plate 233, and a first motor 234. The transmission shaft 231 is rotatably connected to the bearing bracket 21 through a bearing. The runner 232 is fixedly connected to the top end of the transmission shaft 231. One end of the connecting plate 233 is hinged to the runner 232, and the other end of the connecting plate 233 is hinged to the test bench body 1. When the runner 232 rotates, it pulls the test bench body 1 to reciprocate along the slide rail 22 through the connecting plate 233. The output end of the first motor 234 is fixedly connected to the bottom end of the transmission shaft 231.

[0039] Furthermore, the output end of the first motor 234 is connected to the transmission shaft 231 through a coupling. The first motor 234 provides power for the rotation of the transmission shaft 231. Both ends of the connecting plate 233 are connected to the runner 232 and the test bench body 1 respectively through pins. The wear experiment on the strip-shaped sealing brush can be completed by pulling the test bench body 1 to reciprocate along the slide rail 22 through the connecting plate 233.

[0040] In some embodiments, as Figure 2 shown, the second driving member 24 includes a support rod 241, a mounting seat 242, a second motor 243, and a braking member 244. The top end of the support rod 241 is fixedly connected to the bearing bracket 21. The mounting seat 242 is rotatably connected to the support rod 241 through a bearing. When the support rod 241 rotates in the mounting seat 242, it drives the bearing bracket 21 and the test bench body 1 to rotate. The output end of the second motor 243 is fixedly connected to the bottom end of the support rod 241. The braking member 244 is used to limit the rotation of the support rod 241 in the mounting seat 242.

[0041] Further, the output end of the second motor 243 is connected to the support rod 241 through a coupling. The second motor 243 provides power for the rotation of the support rod 241. When performing a wear test on the annular sealing brush, the support rod 241 drives the bearing bracket 21 and the test bench body 1 to rotate. When performing a wear test on the strip-shaped sealing brush, the braking member 244 is used to restrict the rotation of the support rod 241.

[0042] In some embodiments, as Figure 2 shown, the braking member 244 includes a disc 244a and a limit pin 244b. The disc 244a is fixedly connected to the support rod 241, and the limit pin 244b passes through the disc 244a and is threadedly connected to the mounting base 242.

[0043] Further, the disc 244a rotates together with the support rod 241. The outer wall of the limit pin 244b is processed with threads. When the limit pin 244b passes through the disc 244a and is threadedly connected in the mounting base 242, the rotation of the support rod 241 in the mounting base 242 is braked.

[0044] In some embodiments, as Figure 2 shown, the mounting base 242 includes an internal threaded hole 242b for connecting to the limit pin 244b. The internal threaded holes 242b are annularly distributed on the top of the mounting base 242.

[0045] Further, the design of the internal threaded hole 242b facilitates the connection between the bearing bracket 21 and the limit pin 244b after the bearing bracket 21 rotates, so as to determine the use position of the bearing bracket 21.

[0046] In some embodiments, as Figure 2 shown, the mounting base 242 further includes a base 242a, and through holes for connection are processed on the base 242a.

[0047] Further, the base 242a plays a supporting role for the overall mechanism. The design of processing through holes in the base 242a facilitates the fixing of the use position of the base 242a by the connecting member.

[0048] In some embodiments, as Figure 1 and Figure 5 shown, the test bench body 1 further includes a storage groove 11, and the storage groove 11 is used for installing the sealing brush to be tested.

[0049] Further, the design of the storage groove 11 is used to store the strip-shaped sealing brush and the annular sealing brush.

[0050] In some embodiments, as Figure 1 and Figure 4 shown, bolts 12 are threadedly connected in the test bench body 1, and the test bench body 1 is connected to the bearing bracket 21 through the bolts 12.

[0051] Further, two bolts 12 are provided on the test bench body 1. When it is necessary to rotate the annular sealing brush in the test bench body 1, the bolts 12 connect the test bench body 1 and the bearing bracket 21 together to prevent the test bench body 1 from moving along the slide rail 22 under the action of inertia.

[0052] In some embodiments, such as Figure 1 and Figure 5 As shown, a clamping assembly 3 is installed in the test bench body 1. The clamping assembly 3 fixes the sealing brush to be tested in the test bench body 1. The clamping assembly 3 includes a screw 31, a knob 32 and a clamping plate 33. The screw 31 is threadedly connected to the test bench body 1. One end of the screw 31 is fixedly connected to the knob 32, and the other end of the screw 31 is hinged to the clamping plate 33. The rotation of the screw 31 drives the clamping plate 33 to move horizontally to clamp the sealing brush to be tested.

[0053] Further, two screws 31 are provided. The knob 32 is designed to rotate the screw 31. The clamping plate 33 is processed into an arc shape to facilitate fitting with the outer wall of the annular sealing brush and prevent the annular sealing brush from moving during the test.

[0054] In some embodiments, such as Figure 5 As shown, the clamping plate 33 includes strip-shaped lines 331, and the strip-shaped lines 331 are used to increase the friction between the clamping plate 33 and the sealing brush to be tested.

[0055] Further, the strip-shaped lines 331 are provided on the inner side of the clamping plate 33. When clamping the annular sealing brush, the strip-shaped lines 331 increase the friction between the clamping plate 33 and the annular sealing brush, thereby ensuring the stability of the annular sealing brush during the test.

[0056] Working principle:

[0057] When it is necessary to conduct a wear experiment on the strip-shaped sealing brush, insert the strip-shaped sealing brush into the storage slot 11 of the test bench body 1, rotate the screw 31 to drive the clamping plate 33 to move horizontally, and the two clamping plates 33 fix the installation position of the strip-shaped sealing brush. Rotate the limit pin 244b and insert it into the mounting seat 242. Then start the first motor 234. The first motor 234 drives the runner 232 to rotate through the transmission shaft 231. Further, the connecting plate 233 on the runner 232 pulls the test bench body 1 to reciprocate along the slide rail 22. At this time, a wear test is conducted on the strip-shaped sealing brush. Turn off the first motor 234, use the bolt 12 to connect the test bench body 1 and the bearing bracket 21, install the annular sealing brush in the storage slot 11, use the arc surface of the clamping plate 33 to clamp the annular sealing brush tightly, then rotate the limit pin 244b to separate it from the mounting seat 242, and start the second motor 243. The second motor 243 drives the support rod 241 to rotate in the mounting seat 242, and the support rod 241 drives the bearing bracket 21 and the test bench body 1 to rotate, so that a wear experiment can be conducted on the annular sealing brush.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
