Description

Technical Field

[0001] The present invention relates to the technical field of wear-resistant material performance testing equipment, and particularly to a wear-resistant material performance testing device. Background Art

[0002] The bushing is an important component part indispensable on a centrifugal pump. Its function is to connect and seal between the valve body and the shaft body on the centrifugal pump. Therefore, the wear resistance detection on the inner side of the bushing is an essential key detection process before the bushing leaves the factory, which directly determines the sealing performance and service life of the bushing under long-term use. The detection methods of traditional wear resistance detection equipment are relatively single. Usually, a detection piece that fits the inner wall of the bushing is arranged on the inner side of the bushing. By driving the bushing to rotate at a high speed, the wear resistance detection of the inner wall of the bushing is realized. This detection method cannot simulate various complex situations encountered by the bushing in reality, such as the impact force and pressure generated by the water flow in different directions flowing inside the valve body on the inner wall of the bushing, and these detection methods cannot be achieved. There is a lack of a device that can simulate the actual use scenario, detect the wear resistance of the inner wall of the bushing, and adjust the impact force and pressure received by the inner wall of the bushing in real time, so as to enrich the detection data and make the detection result more accurate and effective.

[0011] Beneficial effects of the present invention compared with the prior art: In the present invention, before the wear resistance test of the bushing, the bushing to be tested is placed on the top of the clamping box between two clamping blocks, and the center of the bushing corresponds to the center position of the clamping box. Control the second motor to drive the driving gear to rotate counterclockwise by a certain angle, and then drive the two second rack bars to move synchronously towards the opposite side, and then drive the two clamping blocks to approach both sides of the bushing synchronously until both sides of the bushing are clamped and fixed, so as to facilitate the wear resistance test.

[0012] In the present invention, after the bushing is fixed, in the initial state, the bushing is located near the center of the driving disc. Place several hard detection balls inside the bushing. At this time, control the first motor to work, drive the bushing to rotate counterclockwise while making a clockwise circular motion along with the driving disc, so as to generate a centrifugal force inside the bushing, drive several hard detection balls inside the bushing to move in a circular motion along the lower part of the inner wall of the bushing, and then realize the grinding wear resistance test of the lower part of the inner wall of the bushing. And at this time, because the bushing is close to the center of the driving disc, the grinding impact force of the hard detection balls on the inner wall of the bushing is relatively low. In order to simulate the impact force of water flow on the inner wall of the bushing under different conditions, with the cooperation of the impact force adjustment component, the bushing is gradually moved closer to the inner side of the toothed groove ring. The closer to the inner side of the toothed groove ring, the greater the grinding impact force of the hard detection balls on the inner wall of the bushing, and the farther away from the inner side of the toothed groove ring, the smaller the grinding impact force of the hard detection balls on the inner wall of the bushing. By controlling the first rack bar to move up and down reciprocally, the grinding impact force of the hard detection balls on the inner wall of the bushing is controlled to change from small to large and then from large to small, and cycle repeatedly, so as to realize the effect of enriching the detection method of the wear resistance test of the inner wall of the bushing by changing the size of the grinding impact force on the inner wall of the bushing, thereby expanding the effect of the detection data.

[0013] In the present invention, when the wear resistance test of the inner wall of the bushing is required, first control the first electric push rod to work to drive the driving sleeve to descend until the three hard detection blocks are located at the upper part inside the bushing, and the three hard detection blocks respectively correspond to three different height areas at the upper part of the inner wall of the bushing, and the detection ends of the hard detection blocks are in contact with the inner wall of the bushing. Then when the bushing rotates itself, as the bushing rotates and the three hard detection blocks remain stationary, the wear resistance detection of the upper part of the inner wall of the bushing is realized through the friction between the detection ends of the hard detection blocks and the inner wall of the bushing. During the detection process, with the cooperation of the pressurization component and the pressurization driving 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 bushing during the detection process. The lower the descending height of the connecting column, the greater the pressure exerted by the hard detection block on the inner wall of the bushing, so as to adjust the pressure received by the inner wall of the bushing in real time, thereby enriching the detection data and making the detection result more accurate and effective.

The first bevel gear 236 corresponds to the position of the center of the first gear 215. A second bevel gear 237 is vertically arranged on one side of the first bevel gear 236. And the second bevel gear 237 is rotatably arranged on the top of the driving disc 214. The second bevel gear 237 is meshed with the first bevel gear 236. A first toothed groove rod 238 is arranged on one side of the second bevel gear 237. One end of the first toothed groove rod 238 is connected to the upper part of the connecting column 235. The lower part of the first toothed groove rod 238 is pre-meshed with one side of the second bevel gear 237; It further includes a number of hard detection balls 24. When the shaft sleeve is clamped and fixed by the clamping device 3, a number of hard detection balls 24 are placed at the lower end inside the shaft sleeve for wear resistance testing of the lower part of the inner wall of the shaft sleeve; The clamping device 3 includes a clamping box 31. The clamping box 31 is circularly arranged. 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 arranged at the side end inside the clamping box 31. The output end of the second motor 33 is connected to the center of the driving gear 32. Two second toothed groove rods 34 are respectively arranged at the upper and lower ends of the driving gear 32. The top ends of the two second toothed groove rods 34 respectively pass through both sides of the top of the clamping box 31 and are slidably connected in the horizontal direction. The upper and lower ends of the driving gear 32 are respectively meshed with the toothed groove ends of the two second toothed groove rods 34. Two clamping blocks 35 are symmetrically arranged at the top of the two second toothed groove rods 34. One side of the two adjacent clamping blocks 35 is arc-shaped. And the two clamping blocks 35 are located on both sides of the top of the clamping box 31; Before the wear resistance test of the bushing, place the bushing to be tested on the top of the clamping box 31 between the two clamping blocks 35. The center of the bushing corresponds to the center position of the clamping box 31. Control the second motor 33 to drive the driving gear 32 to rotate counterclockwise by a certain angle, and then drive the two second rack bars 34 to move synchronously towards the opposite side, and then drive the two clamping blocks 35 to approach both sides of the bushing synchronously until both sides of the bushing are clamped and fixed, so as to facilitate the wear resistance test on it; After the bushing is fixed, in the initial state, the third gear 218, the clamping device 3 and the bushing are located near the center of the driving disk 214. Place several hard detection balls 24 inside the bushing. At this time, control the first motor 212 to drive the driving disk 214 to rotate clockwise, and then drive the bushing to rotate clockwise with the driving disk 214. At the same time, the first gear 215 makes a circular motion around the tooth groove ring 213. While making a circular motion, the first gear 215 rotates counterclockwise by itself under the cooperation of the tooth groove ring 213 and will not interfere with the driving rod 216. The rotation of the first gear 215 drives the second gear 217 to rotate clockwise, and then drives the third gear 218 meshing with the second gear 217 to rotate counterclockwise, so that the bushing rotates counterclockwise by itself while making a clockwise circular motion with the driving disk 214, thus generating a centrifugal force inside the bushing, driving several hard detection balls 24 inside the bushing to make a circular motion along the lower part of the inner wall of the bushing, and then realizing the grinding type wear resistance test on the lower part of the inner wall of the bushing. And at this time, because the bushing 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 bushing is relatively low. In order to simulate the impact force of water flow on the inner wall of the bushing under different conditions, first control the first electric push rod 231 to drive the first rack bar 238 to descend and approach the second bevel gear 237. Then control the second electric push rod 233 to drive the connecting column 235 and the first rack bar 238 to continue to descend, so that the first rack bar 238 meshes with the second bevel gear 237 and drives it to rotate, and then drives the first bevel gear 236 to rotate. As the first rack bar 238 descends lower, the deflection angle of the driving rod 216 around the rotation connection with the first bevel gear 236 towards the inner side of the tooth groove ring 213 is larger, making the bushing gradually approach the inner side of the tooth groove ring 213. The closer to the inner side of the tooth groove ring 213, the greater the grinding impact force of the hard detection balls 24 on the inner wall of the bushing, and the farther away from the inner side of the tooth groove ring 213, the smaller the grinding impact force of the hard detection balls 24 on the inner wall of the bushing. By controlling the first rack bar 238 to move up and down reciprocally, the grinding impact force of the hard detection balls 24 on the inner wall of the bushing is controlled to change from small to large and then from large to small, and cycle repeatedly, so as to realize enriching the detection method of the wear resistance test on the inner wall of the bushing by changing the size of the grinding impact force on the inner wall of the bushing, thereby expanding the effect of the detection data.

[0018] In this embodiment, asFigures 6 to 9 As shown, the upper shaft sleeve detection device 4 includes a layered detection component 41, a pressurization drive component 42, and a pressurization component 43.

The side end of the upper part of the drive sleeve 411 is connected to the bottom end of one end of the first mounting plate 232. The lower part of the connecting column 235 passes through the center of the top of the drive sleeve 411 and is located inside the drive sleeve 411. Three pins 413 are evenly arranged in a circular shape on the outer side of the drive sleeve 411, and the three pins 413 are staggered from top to bottom. There are three connecting rods 412, and the tops of the three connecting rods 412 are respectively inserted into the three pins 413. There are three hard detection blocks 414, and the bottom of each connecting rod 412 is provided with a hard detection block 414. The three hard detection blocks 414 are staggered from top to bottom and are evenly distributed in a circular shape on the outer side of the lower part of the drive sleeve 411; The pressurization drive component 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 drive sleeve 411. The other end of the first connecting rod 421 and the other end of the second connecting rod 422 are rotatably connected. An opening is provided at the lower part of the drive sleeve 411 to facilitate the passing of the first connecting rod 421 and the second connecting rod 422. A connecting frame 423 is provided at the rotational connection of the first connecting rod 421 and the second connecting rod 422; The pressurization component 43 includes a first connecting sleeve 431, a second connecting sleeve 432, and a spring 433. The first connecting sleeve 431 is sleeved on the outer side of the three pressurization drive components 42, and the inner side of the first connecting sleeve 431 is respectively connected to the side ends of the three connecting frames 423. Three springs 433 are evenly arranged in a circular shape on the outer side of the first connecting sleeve 431, and the outer side of the first connecting sleeve 431 is respectively connected to one end of the three springs 433. The second connecting sleeve 432 is sleeved on the outer side of the first connecting sleeve 431, and the inner side of the second connecting sleeve 432 is respectively connected to the other end of the three springs 433. 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; The usage method and advantages of the present invention: For this wear-resistant material performance testing device, the working process is as follows: When it is necessary to conduct wear resistance testing on the upper part of the inner wall of the bushing, first control the first electric push rod 231 to work and drive the drive sleeve 411 to descend until the three hard detection blocks 414 are located at the upper part inside the bushing. The three hard detection blocks 414 respectively correspond to three different height areas on the upper part of the inner wall of the bushing, and the detection ends of the hard detection blocks 414 are in contact with the inner wall of the bushing. Then, when the bushing rotates itself, as the bushing rotates and the three hard detection blocks 414 remain stationary, the wear resistance detection of the upper part of the inner wall of the bushing is realized through the friction between the detection ends of the hard detection blocks 414 and the inner wall of the bushing. During the detection process, first disassemble the first toothed groove rod 238 and the connecting column 235 to prevent the position of the bushing from shifting during the detection. Then, control the connecting column 235 to descend through the second electric push rod 233. As the connecting column 235 descends inside the drive sleeve 411, it drives the first connecting rod 421 and the second connecting rod 422 to deflect by a certain angle, and then drives the first connecting sleeve 431 to expand, and then drives several springs 433 to start contracting, and then pressurize the second connecting sleeve 432, so as to pressurize the three hard detection blocks 414 to achieve the effect of controlling the hard detection blocks 414 to pressurize the inner wall of the bushing during the detection. The lower the connecting column 235 descends, the greater the pressure exerted by the hard detection blocks 414 on the inner wall of the bushing, so as to adjust the pressure received by the inner wall of the bushing in real time, and then enrich the detection data, making the detection result more accurate and effective; When a certain amount of wear occurs on the inner wall of the bushing under wear resistance testing, due to the wear of the inner wall of the bushing resulting in a thinner thickness, and because the hard detection blocks 414 always fit with the inner wall of the bushing under the pressure of the second connecting sleeve 432, the hard detection blocks 414 will move towards the inner wall of the bushing. When the wear exceeds the set wear range, the top end of the connecting rod 412 at the top of the hard detection block 414 disengages from the pin 413 on the outside of the drive sleeve 411, causing the hard detection block 414 to disengage from the drive sleeve 411. The hard detection block 414 rotates synchronously with the bushing, thus automatically relieving the pressure of the hard detection block 414 on the inner wall of the bushing and the wear resistance detection. At this time, the tester can stop the start of the first motor 212 by observing this phenomenon, turn off the equipment, and then remove the bushing that has been detected.
