Description

[0002] Alloy refers to a solid product with metallic properties obtained by mixing and melting one metal with another or several metals or non-metals, cooling and solidifying. Among them, alloy wear-resistant sheets are a kind of alloy products. Alloy wear-resistant sheets are usually used for cutting operations. When producing alloy wear-resistant sheets, a batch of samples are usually produced first for performance testing, among which the wear resistance and impact resistance testing of the samples are particularly important.

[0003] Among them, the rotary tiller blades produced with alloy wear-resistant sheets are loaded on rotary tillers for tilling the land. Since the soil is often mixed with gravel or broken bricks of different diameters, the gravel or broken bricks will impact and rub the surface of the rotary tiller blades when the tiller is operating. Therefore, when producing rotary tiller blades, it is necessary to test the wear resistance and impact resistance of the production samples.

The test results obtained in this way cannot fit the actual usage of the alloy wear-resistant sheet.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0040] like Figure 2 and Figure 3 As shown, the force storage member 42 includes a fixed horizontal bar 424 fixedly connected to the upper surface of the fixed platform 43, and the front and rear surfaces of the fixed horizontal bar 424 are provided with limiting sliding grooves 425. The fixed horizontal bar 424 slides left and right and is penetrated by a connecting rod 421. A portal frame 422 is fixedly connected to the fixed horizontal bar 424, and a toggle frame 423 is slidably connected to the horizontal section of the portal frame 422. The bottom end of the toggle frame 423 penetrates the limiting sliding groove 425 and is fixedly connected to the circumferential surface of the connecting rod 421. A second connecting spring is arranged between the toggle frame 423 and the horizontal section of the portal frame 422, and a plurality of auxiliary rollers 426 evenly distributed up and down are rotatably connected to the left front end of the toggle frame 423.

[0041] like Figure 2 and Figure 3 As shown, the impact member 41 includes a screw rod 413 threadedly connected to the left end of the connecting rod 421, and two fastening nuts are arranged on the screw rod 413, one of the fastening nuts is fixedly installed on the left end of the connecting rod 421, and the other fastening nut is threadedly connected to the screw rod 413, and the left end of the screw rod 413 is hinged with an impact head 411, and a telescopic adjustment rod 412 is arranged above the impact head 411, the left end of the telescopic adjustment rod 412 is hinged to the impact head 411, and the right end of the telescopic adjustment rod 412 is hinged to the screw rod 413, and the telescopic adjustment rod 412 is provided with a limit bolt (not shown in the figure) for limiting its telescopic length.

[0042] like Figure 2 , Figure 3 and Figure 4 As shown, the toggle member 44 includes a toggle plate 442 rotatably connected to the rear side of the fixed platform 43, the rear surface of the toggle plate 442 is fixedly connected to an adjusting sleeve 444, the interior of the adjusting sleeve 444 is slidably connected to a toggle rod 443, the adjusting sleeve 444 and the toggle rod 443 are relatively fixed by fastening bolts, the rear surface of the adjusting sleeve 444 is fixedly connected to a connecting sleeve 441, the front surface of the toggle plate 442 is also fixedly connected to a connecting sleeve 441, the two connecting sleeves 441 are coaxial, the connecting sleeve 441 on the front surface of the frontmost toggle plate 442 is fixedly connected to the output shaft of the driving motor, and two adjacent connecting sleeves 441 are connected by a universal shaft (such as Figure 4 As shown), the connecting sleeve 441 is slidably connected with the universal shaft.

[0043] During specific use, first adjust the telescopic length of the telescopic adjustment rod 412 according to the detection needs, so as to adjust the angle between the impact head 411 and the screw rod 413, then screw the screw rod 413 onto the fastening nut on the connecting rod 421, and then rotate the fastening nut on the screw rod 413 toward the connecting rod 421, so that the two fastening nuts are close to each other, and the screw rod 413 is limited by the two fastening nuts, and any tilting direction of the screw rod 413 can be selected. At this time, the position adjustment of the impact head 411 is completed, and the toggle plate 442 is driven by the driving motor to rotate, and the toggle rod 443 rotates with the toggle plate 442 During the movement, a rightward thrust is generated on the toggle frame 423, causing the toggle frame 423 to slide on the horizontal section of the door-shaped frame 422, while driving the connecting rod 421 to slide inside the fixed horizontal bar 424, and compressing the second connecting spring. As the toggle plate 442 rotates, the auxiliary roller 426 is set to make the sliding between the toggle rod 443 and the toggle frame 423 smoother. When the toggle rod 443 is separated from the toggle frame 423, the connecting rod 421 is quickly returned to its original position under the action of the elastic force of the second connecting spring itself, and an impact force is generated on the alloy wear-resistant sheet through the impact head 411, so as to perform an impact force test.

[0044] It should be noted that different angles between the impact head 411 and the screw rod 413 can be selected according to detection needs, and the screw rod 413 and the connecting rod 421 are limited by two fastening nuts, so that the inclination direction of the impact head 411 can be adjusted arbitrarily. At the same time, the extension length of the lever 443 on the adjustment sleeve 444 is different, and the distance that the lever frame 423 is pushed to move will also be different, thereby generating impact forces of different sizes.

[0045] like Figure 1 and Figure 5 As shown, the wear resistance detection mechanism 6 includes a friction member 61 arranged on the left side of the connection mechanism 3 , and a friction medium 62 is clamped on the left side of the friction member 61 .

[0046] like Figure 1 and Figure 8 As shown, the connecting mechanism 3 includes a sliding seat 31 slidably connected to the upper surface of the support frame 2, and a plurality of connecting members 32 are arranged on the upper surface of the sliding seat 31. The plurality of connecting members 32 correspond one by one to the plurality of anti-impact force detection mechanisms 4, and a pushing member 33 is arranged on the connecting member 32.

[0047] like Figure 8 , Fig. 9 and Fig.10As shown, the connecting member 32 includes a mounting seat 324 which is slidably connected to the upper surface of the sliding seat 31, the right side surface of the mounting seat 324 slides left and right and is penetrated by two front-to-back symmetrical first connecting slide bars 321, the right ends of the two first connecting slide bars 321 are commonly fixedly connected to a connecting cross plate 322, the right side surface of the connecting cross plate 322 is fixedly connected to the sliding seat 31, a first connecting spring is sleeved on the circumferential surface of the first connecting slide bar 321 and is located between the mounting seat 324 and the connecting cross plate 322, and an auxiliary roller 323 is fixedly connected to the right side surface of the mounting seat 324 and is located between the two first connecting slide bars 321.

[0048] like Figure 5 , Figure 6 and Figure 7 As shown, the friction member 61 includes a mounting block 613 detachably mounted on the upper surface of the mounting seat 324, the left side surface of the mounting block 613 is clamped with the friction medium 62, the upper surface of the mounting block 613 is connected with a gate-shaped counterweight limit frame 611 from top to bottom and through, the right side surface of the mounting block 613 is fixedly connected with a male pin 614 and a female pin 612 on the front and rear sides respectively, the right side surface of the female pin 612 elastically slides and is through-connected with a limit stop pin 615, the male pin 614 is provided with two limit holes corresponding to the limit stop pin 615, and a through hole is provided in the middle of the mounting block 613, and the through hole corresponds to the position of the impact head 411.

[0049] In specific use, after the angle adjustment of the impact head 411 is completed, the gate-shaped counterweight limit frame 611 is lifted upward, and then the friction medium 62 is clamped on the left side of the mounting block 613, and then the gate-shaped counterweight limit frame 611 is lowered. At this time, the vertical section of the gate-shaped counterweight limit frame 611 is clamped on the friction medium 62, and the friction medium 62 is fixed on the mounting block 613. When multiple mounting blocks 613 are used, first remove the mounting block 613 from the mounting seat 324, and then The male pin 614 on one mounting block 613 is inserted into the female pin 612 on the previous mounting block 613, and the limit pin 615 is pulled out to the right. When the male pin 614 is inserted into the female pin 612, the limit pin 615 is released, and the limit pin 615 is inserted into the limit hole on the male pin 614, so that the two mounting blocks 613 are assembled. After the assembly work of all the mounting blocks 613 is completed, multiple mounting blocks 613 are uniformly installed on the mounting seat 324.

[0050] like Figure 8 , Fig. 9 and Fig.10As shown, the pushing member 33 includes an inclined push block group 331 which is slidably connected to the left side of the connecting cross plate 322, and a fishbone-shaped groove 335 is provided on the lower surface of the inclined push block group 331. A connecting rod 332 is clamped inside the fishbone-shaped groove 335. Two left-right symmetrical clamping strips 336 are provided on the circumferential surface of the connecting rod 332. The clamping strips 336 match the fishbone-shaped groove 335. A pulling plate 333 is slidably connected to the circumferential surfaces of multiple connecting rods 332. A mounting frame 337 is fixedly connected to the right side of the lower surface of the sliding seat 31. Two front-to-back symmetrical electric telescopic rods 334 are fixedly connected to the mounting frame 337. The telescopic ends of the electric telescopic rods 334 are fixedly connected to the lower surface of the pulling plate 333.

[0051] During specific use, after completing the angle adjustment of the impact head 411 and the position adjustment of the friction medium 62, the sliding seat 31 slides to the left on the support frame 2 to move the friction medium 62 and the impact head 411 to the specified position. At the same time, the electric telescopic rod 334 contracts to drive the pushing member 33 to move downward, and the pulling plate 333 cooperates with the connecting rod 332 to generate a downward pulling force on the inclined surface push block group 331. At this time, the inclined surface of the inclined surface push block group 331 slides downward in contact with the auxiliary roller 323, generating a leftward thrust on the mounting seat 324, pressing the friction medium 62 against the alloy wear-resistant plate, and adjusting the distance between the impact head 411 and the alloy wear-resistant plate.

[0052] It should be noted that the downward movement distance of the inclined push block group 331 is different, and the thrust generated on the mounting seat 324 is different. At this time, the pressure generated by the friction medium 62 on the alloy wear-resistant plate is different, thereby changing the size of the friction force. At the same time, the position of the impact head 411 is different, and the impact force generated is different, thereby changing the size of the impact force. By connecting the pull rod 332 at different positions inside the herringbone-shaped slot 335, the distance that the mounting seat 324 is pushed to move can be different. Therefore, according to the detection needs, the card strip 336 can be connected to different positions inside the herringbone-shaped slot 335 to select the appropriate size of the thrust.

[0053] like Figure 1 and Fig.11 As shown, the driving mechanism 5 includes a clamping member 51 arranged on the left side of the upper surface of the base 1 , and a driving member 52 is arranged on the upper surface of the base 1 and at the rear side of the clamping member 51 .

[0054] like Fig.11As shown, the clamping member 51 includes a connecting seat 511 fixedly connected to the upper surface of the base 1, and two left-right symmetrical second connecting slides 512 are fixedly connected inside the connecting seat 511. A supporting seat 513 is connected to the two second connecting slides 512 for a front-back sliding connection, and a supporting platform 514 is connected to the supporting seat 513 for an up-and-down sliding connection. The supporting platform 514 and the supporting seat 513 are relatively fixed by connecting bolts. Two front-and-back symmetrical hydraulic telescopic cylinders 516 are fixedly installed on the top of the left side surface of the supporting seat 513. The telescopic ends of the two hydraulic telescopic cylinders 516 are fixedly connected to a clamping plate 515, and the clamping plate 515 is located on the right side of the supporting seat 513.

[0055] like Fig.10 and Fig.11 As shown, the driving member 52 includes a fixed seat 524 fixedly connected to the upper surface of the base 1, a turntable 522 is rotatably connected to the fixed seat 524, the right side of the turntable 522 is eccentrically rotatably connected to a linkage rod 521, the front end of the linkage rod 521 is hinged with an articulated seat 523, and the front side surface of the articulated seat 523 is fixedly connected to the rear side surface of the supporting seat 513.

[0056] During specific use, when the sliding seat 31 moves on the support frame 2, after moving the impact head 411 and the friction medium 62 to the specified position, the hydraulic telescopic cylinder 516 is extended to push the clamp 515 to move to the right, and then the alloy wear-resistant sheet is placed between the support stand 513 and the clamp 515. The hydraulic telescopic cylinder 516 contracts to clamp the alloy wear-resistant sheet, and then the position of the support platform 514 on the support stand 513 is adjusted, and the support platform 514 is limited by the connecting bolts to support the bottom of the alloy wear-resistant sheet. After the alloy wear-resistant sheet is fixed, the turntable 522 is driven by an external drive to rotate on the fixed seat 524. During the rotation of the turntable 522, the linkage rod 521 pushes the support stand 513 to move back and forth on the second connecting slide rod 512 through the hinged seat 523, thereby starting performance testing.

[0057] According to the detection needs, the above-mentioned different adjustment methods can be selected for combined testing. After the detection is completed, the staff will combine the deformation and damage of the surface of the alloy wear-resistant sheet with the various test conditions applied to the alloy wear-resistant sheet lock, and obtain the results of the wear resistance and impact resistance of the alloy wear-resistant sheet, and comprehensively analyze the performance parameters of the alloy wear-resistant sheet itself.

[0058] like Figure 1-Figure 11As shown, the working principle is: during specific use, the alloy wear-resistant sheet to be tested is first clamped on the clamping member 51, and then a suitable friction medium 62 is selected according to the detection requirements and installed on the friction member 61. At the same time, the impact member 41 is adjusted to a suitable inclination angle according to the detection requirements, and then the friction medium 62 and the impact member 41 are moved to the detection position by the sliding seat 31 on the support frame 2. At this time, the clamping member 51 is driven to move back and forth by the driving member 52, and the friction medium 62 is pressed against the alloy wear-resistant sheet by the pushing member 33 and the connecting member 32 to perform a wear resistance test. The impact member 41 is driven to move back and forth left and right by the toggle member 44 and the force storage member 42, so that the alloy wear-resistant sheet can be tested for impact resistance. At the same time, the combination of the impact member 41 and the friction medium 62 can perform a combined test of impact resistance and wear resistance on the alloy wear-resistant sheet. After the detection is completed, the staff obtains the wear resistance and impact resistance test results of the alloy wear-resistant sheet according to the deformation and damage of the surface of the alloy wear-resistant sheet combined with various factors applied to the alloy wear-resistant sheet.
