Technical Field
[0001] The invention relates to the technical field of wear-resistant material performance testing equipment, in particular to a wear-resistant material performance testing device. Background Art
[0002] The shaft sleeve is an indispensable and important component of the centrifugal pump. Its function is to connect and seal the valve body and the shaft body on the centrifugal pump. Therefore, the wear resistance test of the inner side of the shaft sleeve is an essential key testing process before the shaft sleeve leaves the factory, which directly determines the sealing performance and service life of the shaft sleeve under long-term use. The detection method of traditional wear resistance testing equipment is relatively simple. Usually, a detection part that fits the inner wall of the shaft sleeve is set on the inner side of the shaft sleeve. By driving the shaft sleeve to rotate at high speed, the wear resistance test of the inner wall of the shaft sleeve is realized. This detection method cannot simulate the various complex situations encountered by the shaft sleeve in reality, such as the impact force and pressure generated by water flowing in different directions inside the valve body on the inner wall of the shaft sleeve.

There is a lack of a device that simulates the actual usage scenario, performs wear resistance testing on the inner wall of the shaft sleeve, and adjusts the impact force and pressure on the inner wall of the shaft sleeve in real time, thereby enriching the detection data and making the detection results more accurate and effective.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In the present invention, before the wear resistance test of the shaft sleeve is required, the shaft sleeve to be tested is placed on the top of the clamping box between the two clamping blocks, the center of the shaft sleeve corresponds to the center of the clamping box, and the second motor is controlled to drive the driving gear to rotate counterclockwise by a certain angle, thereby driving the two second toothed rods to move synchronously toward the opposite side, thereby driving the two clamping blocks to approach the two sides of the shaft sleeve synchronously until the two sides of the shaft sleeve are clamped and fixed, so as to facilitate the wear resistance test.
[0014] In the present invention, after the shaft sleeve is fixed, in the initial state, the shaft sleeve is in a position close to the center of the driving disk, and a number of hard detection balls are placed inside the shaft sleeve. At this time, the first motor is controlled to work, driving the shaft sleeve to rotate counterclockwise while performing a clockwise circular motion with the driving disk, thereby generating centrifugal force inside the shaft sleeve, driving the several hard detection balls inside the shaft sleeve to perform a circular motion against the lower part of the inner wall of the shaft sleeve, thereby realizing a grinding wear test on the lower part of the inner wall of the shaft sleeve. At this time, since the shaft sleeve is close to the center of the driving disk, the grinding impact force of the hard detection balls on the inner wall of the shaft sleeve is relatively low. In order to simulate water flow Under different circumstances, the impact force on the inner wall of the sleeve, with the cooperation of the impact force adjustment component, makes the sleeve gradually approach the inner side of the toothed ring. The closer to the inner side of the toothed ring, the greater the grinding impact force of the hard detection ball on the inner wall of the sleeve, and the farther away from the inner side of the toothed ring, the smaller the grinding impact force of the hard detection ball on the inner wall of the sleeve. By controlling the first toothed rod to move back and forth, the grinding impact force of the hard detection ball on the inner wall of the sleeve is controlled from small to large and then from large to small, and so on, thereby achieving the goal of enriching the detection method of the wear resistance test of the inner wall of the sleeve by changing the size of the grinding impact force on the inner wall of the sleeve, thereby expanding the effect of the detection data.
[0015] In the present invention, when it is necessary to perform a wear resistance test on the inner wall of the sleeve, the first electric push rod is first controlled to drive the drive sleeve to descend to the upper part of the inner side of the three hard detection blocks, and the three hard detection blocks correspond to three areas of different heights on the upper part of the inner wall of the sleeve, and the detection ends of the hard detection blocks are in contact with the inner wall of the sleeve. Then, when the sleeve itself rotates, as the sleeve rotates and the three hard detection blocks remain stationary, the wear resistance test of the upper part of the inner wall of the sleeve is achieved through the friction between the detection ends of the hard detection blocks and the inner wall of the sleeve. During the testing process, with the cooperation of the boosting component and the boosting drive component, the three hard detection blocks are pressurized to achieve the effect of controlling the hard detection blocks to pressurize the inner wall of the sleeve during the testing process. The lower the height of the connecting column is lowered, the greater the pressure exerted by the hard detection blocks on the inner wall of the sleeve, thereby adjusting the pressure on the inner wall of the sleeve in real time, thereby enriching the test data and making the test results more accurate and effective.

When the sleeve is clamped and fixed by the clamping device 3, the plurality of hard detection balls 24 are placed at the lower end of the sleeve to perform a wear test on the lower part of the inner wall of the sleeve;
[0033] The clamping device 3 includes a clamping box 31, which is circular in shape. The center of the bottom of the clamping box 31 is connected to the rotation connection of the third gear 218 and the driving rod 216. A driving gear 32 is vertically arranged in the middle of the clamping box 31. A second motor 33 is provided at the side end of the clamping box 31.

The upper and lower ends of the driving gear 32 are respectively meshed with the toothed ends of the two second toothed rods 34. Two clamping blocks 35 are symmetrically arranged on the top of the two second toothed rods 34. The adjacent sides of the two clamping blocks 35 are arranged in an arc shape, and the two clamping blocks 35 are located on both sides of the top of the clamping box 31;
[0034] Before the wear resistance test of the shaft sleeve is required, the shaft sleeve to be tested is placed on the top of the clamping box 31 between the two clamping blocks 35, with the center of the shaft sleeve corresponding to the center of the clamping box 31. The second motor 33 is controlled to drive the driving gear 32 to rotate counterclockwise by a certain angle, thereby driving the two second toothed rods 34 to move synchronously toward the opposite sides, thereby driving the two clamping blocks 35 to synchronously approach the two sides of the shaft sleeve until the two sides of the shaft sleeve are clamped and fixed, so as to facilitate the wear resistance test;
[0035] After the shaft sleeve is fixed, in the initial state, the third gear 218, the clamping device 3 and the shaft sleeve are located near the center of the driving disk 214, and a number of hard detection balls 24 are placed inside the shaft sleeve. At this time, the first motor 212 is controlled to drive the driving disk 214 to rotate clockwise, thereby driving the shaft sleeve to rotate clockwise along with the driving disk 214, and at this time, the first gear 215 performs a circular motion around the toothed ring 213. While performing the circular motion, the first gear 215 rotates counterclockwise with the cooperation of the toothed ring 213, and does not interfere with the driving rod 216. The first gear 215 The rotation of the second gear 217 drives the clockwise rotation of the third gear 218 meshing with the second gear 217 to rotate counterclockwise, thereby driving the shaft sleeve to rotate counterclockwise when the driving disk 214 performs a clockwise circular motion, thereby generating centrifugal force inside the shaft sleeve, driving the several hard detection balls 24 inside the shaft sleeve to perform a circular motion against the lower part of the inner wall of the shaft sleeve, thereby realizing a grinding wear test on the lower part of the inner wall of the shaft sleeve. At this time, since the shaft sleeve is close to the center of the driving disk 214, the grinding impact force of the hard detection balls 24 on the inner wall of the shaft sleeve is relatively low. In order to simulate water The impact force of the flow on the inner wall of the sleeve under different circumstances first controls the first electric push rod 231 to work and drive the first toothed rod 238 to descend close to the second bevel gear 237, then controls the second electric push rod 233 to work and drive the connecting column 235 and the first toothed rod 238 to continue to descend, so that the first toothed rod 238 meshes with the second bevel gear 237 and drives it to rotate, thereby driving the first bevel gear 236 to rotate. As the first toothed rod 238 descends lower, the driving rod 216 is driven to deflect toward the inner side of the toothed ring 213 with the rotation connection point with the first bevel gear 236 as the axis. The greater the degree, the closer the sleeve is to the inner side of the toothed ring 213, the greater the grinding impact force of the hard detection ball 24 on the inner wall of the sleeve, and the farther away from the inner side of the toothed ring 213, the smaller the grinding impact force of the hard detection ball 24 on the inner wall of the sleeve. By controlling the first toothed rod 238 to move back and forth, the grinding impact force of the hard detection ball 24 on the inner wall of the sleeve is controlled to change from small to large and then from large to small, and repeat this cycle, thereby achieving the goal of enriching the detection method of the wear resistance test of the inner wall of the sleeve by changing the size of the grinding impact force on the inner wall of the sleeve, thereby expanding the effect of the detection data.

The side end of the upper part of the drive sleeve 411 is connected to the first mounting plate 232. 2 is connected to the bottom of one end, the lower part of the connecting column 235 passes through the center of the top of the driving sleeve 411 and is located inside the driving sleeve 411. The outside of the driving sleeve 411 is evenly provided with three latches 413 in a circular shape, and the three latches 413 are staggered from top to bottom. There are three connecting rods 412, and the tops of the three connecting rods 412 are respectively plugged with the three latches 413.

[0037] The boost drive assembly 42 includes a first connecting rod 421, a second connecting rod 422 and a connecting frame 423. One end of the first connecting rod 421 is rotatably connected to the outer side of the bottom of the connecting column 235, one end of the second connecting rod 422 is rotatably connected to the outer side of the bottom of the driving sleeve 411, and the other end of the first connecting rod 421 is rotatably connected to the other end of the second connecting rod 422. The lower part of the driving sleeve 411 is provided with an opening for facilitating the passage of the first connecting rod 421 and the second connecting rod 422. The connecting frame 423 is provided at the rotatable connection between the first connecting rod 421 and the second connecting rod 422.

The outer side of the second connecting sleeve 432 is respectively abutted against the side ends of the three hard detection blocks 414. The first connecting sleeve 431 and the second connecting sleeve 432 are flexibly arranged.
[0039] The use method and advantages of the present invention: The working process of the wear-resistant material performance testing device is as follows:
[0040] When it is necessary to perform a wear test on the upper part of the inner wall of the sleeve, first control the first electric push rod 231 to work and drive the drive sleeve 411 to descend to the upper part of the inner side of the sleeve where the three hard detection blocks 414 are located, and the three hard detection blocks 414 correspond to three areas of different heights on the upper part of the inner wall of the sleeve, and the detection ends of the hard detection blocks 414 are in contact with the inner wall of the sleeve. Then, when the sleeve rotates itself, as the sleeve rotates and the three hard detection blocks 414 remain stationary, the wear test of the upper part of the inner wall of the sleeve is achieved through the friction between the detection ends of the hard detection blocks 414 and the inner wall of the sleeve. During the detection process, the first toothed rod 238 and the connecting column 235 are first disassembled to avoid the position of the sleeve from being offset during the detection process. Then, the second electric push rod 231 is used to control the first toothed rod 238 and the connecting column 235 to drive the drive sleeve 411 to descend to the upper part of the inner side of the sleeve. The movable push rod 233 controls the connection column 235 to descend. As the connection column 235 descends inside the drive sleeve 411, the first connecting rod 421 and the second connecting rod 422 are deflected by a certain angle, thereby driving the first connection sleeve 431 to expand, and then driving the plurality of springs 433 to begin to contract, thereby pressurizing the second connection sleeve 432, thereby pressurizing the three hard detection blocks 414 to achieve the effect of controlling the hard detection blocks 414 to pressurize the inner wall of the sleeve during the detection process. The lower the connection column 235 descends, the greater the pressure exerted by the hard detection blocks 414 on the inner wall of the sleeve, thereby adjusting the pressure on the inner wall of the sleeve in real time, thereby enriching the detection data and making the detection results more accurate and effective.
[0041] When the inner wall of the sleeve produces a certain amount of wear under the wear resistance test, the thickness of the inner wall of the sleeve becomes thinner due to the wear, and the hard detection block 414 is always in contact with the inner wall of the sleeve under the pressure of the second connecting sleeve 432, so the hard detection block 414 will move toward the inner wall of the sleeve. When the wear exceeds the set wear range, the top of the connecting rod 412 at the top of the hard detection block 414 is disengaged from the pin 413 on the outside of the drive sleeve 411, so that the hard detection block 414 is disengaged from the drive sleeve 411, and the hard detection block 414 rotates synchronously with the sleeve, thereby automatically releasing the pressure and wear resistance detection of the hard detection block 414 on the inner wall of the sleeve. At this time, the inspector can stop starting the first motor 212 by observing this phenomenon, turn off the equipment and remove the sleeve that has been inspected.
