[0023] Such as Figure 1 And Figure 2As shown in the figure, a positioning tooling for a Shore hardness tester calibration device includes a base 1. A support frame 1.1 is fixedly connected to the rear of the upper side wall of the base 1. A first slider 1.2 is slidably arranged between the inner walls on both sides of the support frame 1.1. A first screw rod 1.3 is rotatably arranged on the lower inner wall of the support frame 1.1. The upper end of the first screw rod 1.3 threadedly passes through the first slider 1.2 and extends above the support frame 1.1 and is fixedly connected to a first knob 1.4. A lifting plate 1.5 is fixedly connected to the front side wall of the first slider 1.2. A groove 1.6 is formed on one side of the front side wall of the lifting plate 1.5 and a standard part 1.51 is installed on the other side. A second slider 1.7 is slidably arranged in the groove 1.6. A follower plate 1.8 is fixedly connected to the front side wall of the second slider 1.7. A calibration block 1.9 is also fixedly connected to the upper side wall of the base 1. Rotating the first knob 1.4 can drive the first screw rod 1.3 to rotate. When the first screw rod 1.3 rotates, it can make the first slider 1.2 threadedly connected thereto drive the lifting plate 1.5 to move downward, so that the standard part 1.51 and the indenter of the Shore hardness tester to be calibrated measure the hardness of the calibration block 1.9. At this time, the data displayed on the standard part 1.51 and the data displayed on the Shore hardness tester to be calibrated are compared. If they are the same, no calibration is required. If they are different, the Shore hardness tester to be calibrated needs to be adjusted and calibrated. A positioning assembly 2 is arranged on the front side wall of the follower plate 1.8.
[0024] Specifically, as Figure 3 shown in the figure, a positioning tooling for a Shore hardness tester calibration device, the positioning assembly 2 includes a fixed block 2.1, a top plate 2.2, a cavity 2.3, a micro air pump 2.4, a three-way pipe 2.5, an L-shaped air inlet pipe 2.6, a connecting pipe 2.7 and a solenoid valve 2.71. Two symmetrically distributed fixed blocks 2.1 are fixedly connected to the front side wall of the follower plate 1.8. A top plate 2.2 is fixedly connected between the upper side walls of the two fixed blocks 2.1. A plurality of equidistantly distributed cavities 2.3 are formed in the fixed block 2.1. A micro air pump 2.4 is installed on the upper side wall of the top plate 2.2. The exhaust end of the micro air pump 2.4 is communicated with a three-way pipe 2.5. The other two ends of the three-way pipe 2.5 are respectively communicated with an L-shaped air inlet pipe 2.6. The cavity 2.3 is connected to the L-shaped air inlet pipe 2.6 through a connecting pipe 2.7. A solenoid valve 2.71 is installed on the connecting pipe 2.7. The air pump 2.4 can convey air into the two L-shaped air inlet pipes 2.6 through the three-way pipe 2.5, and then the air enters each cavity 2.3 in the fixed block 2.1 through the connecting pipe 2.7. The top plate 2.2 can block the Shore hardness tester to be measured, preventing the Shore hardness tester to be calibrated from sliding upward when pressing down on the calibration block 1.9 for measurement.
[0025] Specifically, as Figure 4As shown in the figure, a positioning tooling for a Shore hardness tester calibration device. The positioning component 2 further includes a piston 2.8, a push rod 2.9, clamping blocks 2.10, a pressure sensor 2.101, and a return spring 2.102. A piston 2.8 is arranged in the cavity 2.3. A push rod 2.9 is fixedly connected to the side wall of the piston 2.8 away from the connecting pipe 2.7. The other end of the push rod 2.9 extends to the outside of the fixed block 2.1 and is fixedly connected to a clamping block 2.10. A pressure sensor 2.101 is installed on the side wall of the clamping block 2.10 away from the push rod 2.9. A return spring 2.102 is arranged between the clamping block 2.10 and the fixed block 2.1. The return spring 2.102 is sleeved on the outside of the push rod 2.9. When air enters the cavity 2.3, the piston 2.8 will move, and the piston 2.8 drives the push rod 2.9 to move, so that the clamping blocks 2.10 on both sides move synchronously closer to the Shore hardness tester to be calibrated. If the side walls of the Shore hardness tester to be calibrated are uneven, there will be two clamping blocks 2.10 that first contact the Shore hardness tester to be calibrated. After the clamping blocks 2.10 on both sides contact the Shore hardness tester to be calibrated, the pressure sensor 2.101 will sense the pressure. When the pressure reaches the preset value, the controller 3 controls the solenoid valve 2.71 on the connecting pipe 2.7 corresponding to the clamping block 2.10 to close, so that the clamping block 2.10 no longer moves, and the remaining clamping blocks 2.10 continue to move closer to the Shore hardness tester to be calibrated. After all the clamping blocks 2.10 contact the Shore hardness tester to be calibrated, the air pump 2.4 and all the solenoid valves 2.71 are closed, and the Shore hardness tester to be calibrated can be clamped and fixed. It is applicable to Shore hardness testers with irregular side walls and also applicable to Shore hardness testers with flat side walls, with higher applicability.
[0026] Specifically, as Figure 3 shown in the figure, a positioning tooling for a Shore hardness tester calibration device. A second screw 1.61 is rotatably arranged on the lower side wall of the groove 1.6. The upper end of the second screw 1.61 threadedly passes through the second slider 1.7 and extends above the lifting plate 1.5 and is fixedly connected to a second knob 1.62. Rotating the second knob 1.62 can drive the second screw 1.61 to rotate. When the second screw 1.61 rotates, the second slider 1.7 threadedly connected to it can drive the follower plate 1.8 to move up and down, finely adjusting the height of the Shore hardness tester to be calibrated so that its indenter is flush with the calibration line 1.11, thereby making the indenter of the standard part 1.51 and the Shore hardness tester to be calibrated flush, ensuring the accuracy of the data during measurement.
[0027] Specifically, as Figure 2 shown in the figure, a positioning tooling for a Shore hardness tester calibration device. Calibration lines 1.11 are respectively arranged on both sides of the front side wall of the support frame 1.1, used to observe whether the indenter of the Shore hardness tester to be calibrated is flush with the indenter of the standard part 1.51.
[0028] Specifically, as Figure 3As shown in the figure, a positioning tooling for a Shore hardness tester calibration device. An exhaust cap is provided at the bottom end of the L-shaped air inlet pipe 2.6 for discharging the air inside the L-shaped air inlet pipe 2.6.
[0029] Specifically, as Figure 1 shown in the figure, a positioning tooling for a Shore hardness tester calibration device. A controller 3 is installed on the base 1. The controller 3 can receive the electrical signals transmitted by the pressure sensor 2.101 and make corresponding controls on the solenoid valve 2.71 and the air pump 2.4 according to the electrical signals.
[0030] In the specific implementation of the present utility model, the Shore hardness tester to be calibrated is placed between two fixing blocks 2.1, and the Shore hardness tester to be calibrated is made to abut against the top plate 2.2. Then, the air pump 2.4 is started through the controller 3. The air pump 2.4 conveys air through the three-way pipe 2.5 into the two L-shaped air inlet pipes 2.6. Then, the air enters into each cavity 2.3 inside the fixing block 2.1 through the connecting pipe 2.7, pushing the piston 2.8 to move. The piston 2.8 drives the push rod 2.9 to move, so that the clamping blocks 2.10 on both sides approach the Shore hardness tester to be calibrated synchronously. If the two side walls of the Shore hardness tester to be calibrated are uneven, there will be two clamping blocks 2.10 that first contact the Shore hardness tester to be calibrated. After the clamping blocks 2.10 on both sides have contacted the Shore hardness tester to be calibrated, the pressure sensor 2.101 will sense the pressure. When the pressure reaches the preset value, the controller 3 controls the solenoid valve 2.71 on the connecting pipe 2.7 corresponding to the clamping block 2.10 to close, so that this clamping block 2.10 no longer moves, and the remaining clamping blocks 2.10 continue to approach the Shore hardness tester to be calibrated. After all the clamping blocks 2.10 have contacted the Shore hardness tester to be calibrated, the air pump 2.4 and all the solenoid valves 2.71 are closed, and thus the Shore hardness tester to be calibrated can be clamped and fixed. It is applicable to Shore hardness testers with irregular side walls and also applicable to Shore hardness testers with flat side walls, with higher applicability. After positioning the Shore hardness tester to be calibrated, observe whether the indenter of the Shore hardness tester to be calibrated is flush with the calibration line 1.11. If not, the second knob 1.62 can be rotated to drive the second screw 1.61 to rotate. When the second screw 1.61 rotates, it can make the second slider 1.7 threadedly connected thereto drive the follower plate 1.8 to move up and down, finely adjusting the height of the Shore hardness tester to be calibrated to make its indenter flush with the calibration line 1.11, so that the indenter of the standard part 1.51 and the Shore hardness tester to be calibrated are flush, ensuring the accuracy of the data during measurement. The standard part 1.51 is a standard Shore hardness tester. During measurement, the first knob 1.4 is rotated to drive the first screw 1.3 to rotate. When the first screw 1.3 rotates, it can make the first slider 1.2 threadedly connected thereto drive the lifting plate 1.5 to move downward, so that the indenter of the standard part 1.51 and the Shore hardness tester to be calibrated measure the hardness of the calibration block 1.9. At this time, the data displayed on the standard part 1.51 and the data displayed on the Shore hardness tester to be calibrated are compared. If they are the same, no calibration is required. If they are different, the Shore hardness tester to be calibrated needs to be adjusted and calibrated.
