Detailed implementation mode

[0031] Refer to Figure 1, a wear resistance performance testing device of the present invention includes a workbench 1, a console 2, a material switching turntable 3, a material conveying and replacing mechanism 4, a friction disc 5, a lifting control mechanism 6, a friction rotation power motor 7, a material rod bearing mechanism 8, a counterweight adjustment mechanism 9 and a detection mechanism 10. A console 2 for the operating state of the device is arranged on the workbench 1. Detection data is obtained through the console 2, and the operation of the device is controlled. The type of the console 2 is a computer. A material switching turntable 3 for switching friction materials is arranged on the workbench 1. At least two material conveying and replacing mechanisms 4 are arranged on the material switching turntable 3. Friction discs 5 are stacked vertically on the material conveying and replacing mechanism 4. Friction discs 5 with different roughnesses can be arranged on the material conveying and replacing mechanism 4. By rotating the material switching turntable 3, the friction disc 5 is opposed to the material to be detected. After a friction disc 5 is used, the used friction disc 5 needs to be removed through the material conveying and replacing mechanism 4, and at the same time, a new friction disc 5 is replaced. A lifting control mechanism 6 is arranged on the workbench 1 on the side of the material switching turntable 3. A friction rotation power motor 7 is arranged vertically on the lifting control mechanism 6. A material rod bearing mechanism 8 is fixedly arranged on the rotating shaft of the friction rotation power motor 7. A counterweight adjustment mechanism 9 for adjusting the friction pressure and a detection mechanism 10 for detecting the friction effect of the material are arranged on the material rod bearing mechanism 8. The distance between the material rod bearing mechanism 8 and the material conveying and replacing mechanism 4 is adjusted by lifting through the lifting control mechanism 6, which is convenient for replacing the material to be detected.

[0032] 4 material conveying and replacing mechanisms 4 are arranged on the material switching turntable 3. The number of the material conveying and replacing mechanisms 4 is specifically set according to needs. The more parameters that need to be obtained for different materials to be detected under different conditions, and the more friction discs 5 with different roughnesses need to be applied, the more material conveying and replacing mechanisms 4 need to be equipped. As Figure 2 shown, the material switching turntable 3 includes a material switching motor 31, a material switching shaft 32 and a material switching disc seat 33. The lower end of the material switching shaft 32 is vertically fixedly arranged on the rotating shaft of the material switching motor 31. The upper end of the material switching shaft 32 is fixedly provided with a material switching disc seat 33. By driving the material switching shaft 32 and the material switching disc seat 33 to rotate through the material switching motor 31, the purpose of switching the friction disc 5 is achieved.

[0033] As Figure 3 and Figure 4As shown, the material conveying and replacing mechanism 4 includes a material conveying and carrying bucket 41, a material conveying and supplying motor 42, a material conveying and supplying screw sleeve 43, a material conveying and supplying lead screw 44, a material conveying and supplying top plate 45, and a material replacing actuator 46. A material conveying and supplying screw sleeve 43 is connected to the rotating shaft of the material conveying and supplying motor 42. The material conveying and supplying lead screw 44 passes through the bottom of the material conveying and carrying bucket 41 and is inserted into the material conveying and supplying screw sleeve 43. Inside the material conveying and carrying bucket 41 at the upper end of the material conveying and supplying lead screw 44, a material conveying and supplying top plate 45 for supporting the material is fixedly provided. A material replacing actuator 46 for removing the used friction disc 5 from the equipment is arranged on the side of the material conveying and carrying bucket 41. The material conveying and supplying motor 42 drives the material conveying and supplying screw sleeve 43 to rotate. The material conveying and supplying screw sleeve 43 drives the material conveying and supplying lead screw 44 to move up and down. Finally, the friction disc 5 is pushed upward by the material conveying and supplying top plate 45, and the used material is removed from the equipment by the material replacing actuator 46. As Figure 3 and Figure 4 shown, a limiting guide rail 411 for restricting the rotation of the friction disc 5 is arranged on the inner wall of the material conveying and carrying bucket 41. A plurality of material replacing limiting grooves 51 are arranged on the friction disc 5. The limiting guide rail 411 is placed in the limiting groove. The upper end of the limiting guide rail 411 is flush with the upper edge of the material conveying and carrying bucket 41. When the material rotates on the friction disc 5, in order to prevent the friction disc 5 from rotating with the material, the friction disc 5 can be fixed by placing the limiting guide rail 411 in the material replacing limiting groove 51, as long as more than one limiting guide rail 411 is located in the material replacing limiting groove 51. The material replacing actuator 46 includes a material replacing actuator motor, a material replacing actuator shaft 462, and a material replacing actuator clamping plate 463. A material replacing actuator motor is fixedly provided at the bottom outside the material conveying and carrying bucket 41. A material replacing actuator shaft 462 is connected to the rotating shaft of the material replacing actuator motor. A material replacing actuator clamping plate 463 is fixedly provided at the upper end of the material replacing actuator shaft 462. The material replacing actuator clamping plate 463 is located in one of the limiting grooves. The lower edge of the material replacing actuator clamping plate 463 is higher than the upper edge of the limiting guide rail 411. Normally, the friction disc 5 and the material slide relative to each other by friction. When the friction disc 5 is used up, all the frictions are lifted by the material conveying and replacing mechanism 4. Finally, the uppermost friction disc 5 is higher than the upper edge of the material conveying and carrying bucket 41. At this time, the limiting guide rail 411 is separated from the limiting groove on the friction disc 5. At this time, the material replacing actuator clamping plate 463 is located in the limiting groove. The material replacing actuator motor drives the material replacing actuator shaft 462 to rotate. The material replacing actuator shaft 462 drives the material replacing actuator clamping plate 463 to rotate. The friction disc 5 is driven to rotate by the material replacing actuator clamping plate, and finally the friction disc 5 is rotated out of the material conveying and carrying bucket 41 to achieve the purpose of replacing the friction disc 5. As Figure 5 andFigure 6 As shown, the friction disc 5 includes an inner tray 52 and an outer fixing ring 53. The inner tray 52 is elastically embedded in the outer fixing ring 53. The outer fixing ring 53 is fixedly connected to the inner tray 52 by the elasticity of the outer fixing ring 53. The surface of the inner tray 52 can be used as a friction material, or the inner tray 52 can be wrapped with cloth of different roughness, and the edge of the cloth is fixed by the outer fixing ring 53. This method can achieve the purpose of being applicable to soft cloth. When it is necessary to test the wear resistance of the cloth, it is only necessary to fix the cloth on the friction disc 5, and use the material conveying and changing mechanism 4 to carry rods of different roughness to perform friction experiments on the cloth. This allows the equipment to be used for testing the friction performance of hard rod-shaped materials, and is also suitable for testing soft materials like cloth. Compared with traditional friction testing equipment, the adaptability of the equipment is improved. Figure 7 As shown, the lifting control mechanism 6 includes a lifting control fixed seat 61, a lifting control vertical plate seat 62, a lifting control guide rail 63, a lifting seat body 64, a lifting plate seat 65, a lifting screw rod 66, a lifting motor 68 seat 67 and a lifting motor 68. The lifting control fixed seat 61 is horizontally fixed at the lower end of the lifting control vertical plate seat 62, and the lifting control guide rail 63 is vertically arranged on the side of the lifting control vertical plate seat 62. The lifting control guide rail 63 is arranged on the lifting seat body 64, and the lifting seat body 64 is horizontally fixed with a lifting device. Plate seat 65, a lifting screw rod 66 is vertically fixed on the lifting control vertical plate seat 62, and the lifting screw rod 66 passes through the threaded sleeve on the lifting seat body 64. A lifting motor 68 seat 67 is fixed on the side of the lifting control vertical plate seat 62, and a lifting motor 68 is fixed on the lifting motor 68 seat 67. The lifting motor 68 is connected to the lifting screw rod 66 through a transmission belt transmission. The lifting motor 68 drives the lifting screw rod 66 to rotate, and the lifting seat body 64 is driven to rise and fall through the lifting screw rod 66, and finally drives the lifting plate seat 65 to rise and fall.

[0034] like Figure 8 Figure 11 As shown, the material rod bearing mechanism 8, the material storage turntable 81, the storage measurement hole group 82 and the debris removal hole 83, the material storage turntable 81 is provided with a plurality of storage measurement hole groups 82 and debris removal holes 83 with different distances from the center of the material storage turntable 81, the storage measurement hole group 82 includes a material rod storage hole 821 for placing the material rod whose wear resistance is to be tested, a measurement hole 822 for detecting the height of the material rod whose wear resistance is to be tested, and a counterweight storage hole 823 for storing spare counterweights, and a fan mechanism 11 is installed on the debris removal hole 83. The specific number of the storage measurement hole group 82 and the debris removal hole 83 is 4. Because the distances between the storage measurement hole group 82 and the center of the material storage turntable 81 are different, the linear speed during the rotation process is also different. The rotation speeds of the material rod whose wear resistance is to be tested in the material rod storage hole 821 are different, so the wear resistance of the material can be tested at different rotation speeds.Figure 12 and Figure 13 As shown in Figure 13 , the counterweight adjustment mechanism 9 includes a counterweight protection cylinder 91, a counterweight adjustment roller 92, a counterweight adjustment motor 93, and a counterweight chain 94. A counterweight adjustment motor 93 is fixedly provided on the outer side of the upper end of the counterweight protection cylinder 91. A counterweight adjustment roller 92 is connected to the rotating shaft of the counterweight adjustment motor 93. The counterweight chain 94 bypasses the counterweight adjustment roller 92. A transfer hole is provided on the counterweight adjustment roller 92. The counterweight chain 94 includes a counterweight connection line 941 and counterweight balls 942. The counterweight balls 942 are fixedly provided on the counterweight connection line 941 at a certain interval. The counterweight balls 942 wound on the counterweight adjustment roller 92 are located in the transfer hole. One end of the counterweight chain 94 is located in the material rod storage hole 821, and the other end is located in the counterweight storage hole 823. By driving the counterweight adjustment roller 92 to rotate through the counterweight adjustment motor 93, and driving the counterweight chain 94 to rotate through the counterweight adjustment roller 92, more counterweight balls 942 can be conveyed into the counterweight storage hole 823 to reduce the pressure between the material rod to be tested for wear resistance and the friction disc 5, or more counterweight balls 942 can be conveyed into the material rod storage hole 821 to increase the pressure between the material rod to be tested for wear resistance and the friction disc 5. As Figure 14 shown in Figure 14 , the detection mechanism 10 includes a guide rod 101, a sliding sleeve 102, a driven disc 103, and a resistance measuring instrument. The sliding sleeve 102 slides on the guide rod 101. A resistance measuring instrument for measuring resistance is provided between one end of the guide rod 101 and the sliding sleeve 102. The driven disc 103 is located in the material rod storage hole 821. The sliding sleeve 102 and the driven disc 103 are fixedly connected. A pressure sensor for detecting the counterweight pressure is provided at the lower end of the driven disc 103. The end of the counterweight chain 94 is fixedly provided on the driven disc 103. A suspension rope is fixedly connected between the driven disc 103 and the material rod to be tested for wear resistance. When the length of the material rod to be tested for wear resistance becomes shorter with the friction, the height of the driven disc 103 will also decrease. By the change in the resistance between the sliding sleeve 102 and the guide rod 101, the change value of the height can be correspondingly obtained. At the same time, the counterweight balls 942 press on the driven disc 103, and the driven disc 103 fits against the end of the material rod to be tested for wear resistance. The gravity of the counterweight balls 942 can be detected through the pressure sensor between the material rod to be tested for wear resistance and the driven disc 103. Adjustment can be made according to the detection result. When the friction disc 5 needs to be replaced, the lower end of the material rod needs to be raised. Otherwise, the new grinding disc will interfere with the lower end of the material rod, and at the same time, the material rod will also fall under the action of gravity. When replacing the friction disc 5, the counterweight chain 94 is driven by the counterweight adjustment roller 92 to move, so that the counterweight chain 94 lifts the driven disc 103, and the driven disc 103 then lifts the material rod through the suspension rope, so as to prevent the material rod from falling due to gravity during the process of replacing the friction disc 5.

[0035] The working process of the present invention:

[0036] During the operation of a wear resistance testing device of the present invention, first, the material to be tested is processed into a rod shape, and then the material rod is placed in the material rod storage hole 821 from the lower part. Then, the lifting motor 68 drives the lifting lead screw 66 to rotate, and the lifting lead screw 66 drives the lifting seat body 64 to lift, finally driving the lifting plate seat 65 to lift, so that the material rod bearing mechanism 8 and the material conveying and replacing mechanism 4 maintain a set distance. The lower end of the material rod is attached to the friction disk 5. Then, the friction rotation power motor 7 drives the material rod bearing mechanism 8 to rotate, finally driving the material rod to rub on the friction disk 5. The weight adjustment motor 93 drives the weight adjustment roller 92 to rotate, and the weight adjustment roller 92 drives the weight chain 94 to rotate, so that more weight balls 942 can be conveyed into the weight storage hole 823, reducing the pressure between the material rod to be tested for wear resistance and the friction disk 5. Also, more weight balls 942 can be conveyed into the material rod storage hole 821, increasing the pressure between the material rod to be tested for wear resistance and the friction disk 5, ultimately achieving the purpose of adjusting the pressure. When the material rod to be tested for wear resistance becomes shorter with the friction length, the height of the driven disk 103 will also decrease. Through the resistance change between the sliding sleeve 102 and the guide rod 101, the change value of the height can be correspondingly obtained. At the same time, the weight ball 942 presses on the driven disk 103, and the driven disk 103 is attached to the end of the material rod to be tested for wear resistance. The gravity of the weight ball 942 can be detected through the pressure sensor between the material rod to be tested for wear resistance and the driven disk 103, and adjustment can be made according to the detection result. When the friction disk 5 needs to be replaced, the lower end of the material rod needs to be raised, otherwise the new grinding disk will interfere with the lower end of the material rod, and the material rod will also fall under the action of gravity. When replacing the friction disk 5, the weight adjustment roller 92 drives the weight chain 94 to move, so that the weight chain 94 hoists the driven disk 103, and the driven disk 103 then hoists the material rod through the suspension rope, achieving the purpose of preventing the material rod from falling due to gravity during the process of replacing the friction disk 5. When different roughness friction disks 5 need to be replaced, the material switching motor 31 drives the material switching shaft 32 and the material switching disk seat 33 to rotate, achieving the purpose of switching the friction disk 5. When the grinding disks in the same material conveying and carrying bucket 41 are used up, the material conveying and supply motor 42 drives the material conveying and supply screw sleeve 43 to rotate, and the material conveying and supply screw sleeve 43 drives the material conveying and supply lead screw 44 to lift. Finally, the friction disk 5 is pushed upward by the material conveying and supply top plate 45, and the used materials are discharged from the device through the material replacement actuator 46. When the wear resistance of flexible planar materials such as fabrics needs to be detected, only the fabric needs to be fixed on the friction disk 5, and the material conveying and replacing mechanism 4 can be used to carry rods with different roughness to conduct friction experiments on the fabric, enabling the device to be used for detecting the friction performance of hard rod-shaped materials. Through the elasticity of the outer fixing ring 53, the outer fixing ring 53 is fixedly connected to the inner tray 52. Different roughness fabrics can be wrapped on the inner tray 52, and the edge of the fabric is fixed by the outer fixing ring 53.This method can achieve the purpose of being applicable to soft fabrics when the abrasion resistance of the fabric needs to be detected.

[0037] An abrasion resistance test device of the present invention can automatically replace the friction disc 5 with different roughnesses for friction experiments through the material switching turntable 3, the material conveying and replacing mechanism 4, the friction disc 5, the lifting control mechanism 6, the friction rotation power motor 7, the material rod bearing mechanism 8, the weight adjustment mechanism 9 and the detection mechanism 10, and can automatically remove the used friction disc 5. At the same time, it can automatically adjust the weight. The device can be used for the abrasion resistance test of hard materials and also for the abrasion resistance test of soft fabrics. It has strong adaptability and high automation degree, can meet the rapid abrasion resistance detection under a large number of variable conditions, can reduce the manual labor time and improve the test efficiency.
