[0027] Example 1

[0028] Please refer to Figures 1-7 In the figure, a sensitivity detection tooling for a pneumatic actuator provided in this embodiment includes: a tooling main body 1. A moving plate 4 is provided at the upper end of the tooling main body 1. A clamping block 2 is installed on the moving plate 4.

[0030] Secondly, through the settings of the electric telescopic rod 501, the leveling screw rod 502 and the adjusting nut 503 in the leveling assembly, the clamping block 2 can be quickly lifted, which is convenient for placing the piston part of the pneumatic actuator and for leveling the clamping block 2, improving the detection accuracy.

[0031] Example 2

[0032] On the basis of Embodiment 1, a rubber block 201 is provided in the clamping cavity 209 relative to the clamping plate 204; support blocks 3 are respectively provided on both sides of the top of the tooling main body 1. A moving groove 301 is provided on one side of each of the two support blocks 3. A sliding rod 302 is provided inside the two moving grooves 301. Slide holes 403 are respectively provided on both sides of the moving plate 4. The two sliding rods 302 are respectively slidably connected with the two slide holes 403; indicating needles a7 are respectively provided on one side of the two support blocks 3, and a plurality of indicating needles b701 corresponding to the plurality of clamping cavities 209 are respectively provided on the clamping block 2; a partition plate 6 is provided inside the tooling main body 1. A through hole b601 is provided on the partition plate 6, and a plurality of positioning holes b608 are provided on the top of the partition plate 6. A plurality of limiting rods 603 are provided below the partition plate 6. An activity plate 602 is provided corresponding to the through hole b601 below the partition plate 6. The activity plate 602 is slidably matched with the limiting rods 603. A pressing block 604 is fixedly connected to the bottom of the activity plate 602. A compression spring 605 is sleeved on the pressing block 604. The lower end of the compression spring 605 is fixedly connected to a spring seat 606. A pressure sensor 607 is provided at the bottom of the spring seat 606. A display panel 101 electrically connected to the pressure sensor 607 is installed on one side of the tooling main body 1; the bottom ends of the plurality of leveling screws 502 all protrude from the bottom of the clamping block 2 and are fixedly connected to the moving plate 4; pulling blocks 402 are respectively provided on both sides of the moving plate 4. A positioning hole a404 is provided at the top of one side of the pulling block 402. A positioning rod 405 is provided above the pulling block 402, and one end of the positioning rod 405 passes through the positioning hole a404 and is snap-fitted with the positioning hole b608.

[0033] When it is necessary to detect the pneumatic actuator, the staff can respectively place a plurality of pneumatic actuators inside the clamping cavity 209, and make one side of the pneumatic actuator lean against the rubber block 201. Then, manually rotate the T-shaped screw 205 on one side of the telescopic block 208, so that the T-shaped screw 205 rotates with the threaded hole provided on one side of the telescopic block 208, so that one end of the T-shaped screw 205 rotates on the bearing on one side of the connecting plate 206, thereby driving the connecting plate 206 and the clamping plate 204 to move in the direction close to the pneumatic actuator until one side of the clamping plate 204 is in contact with the pneumatic actuator to complete the clamping of the pneumatic actuator;

[0034] Furthermore, the staff can control the extension of the plurality of electric telescopic rods 501 inside the clamping block 2 to facilitate the placement of the piston part of the pneumatic actuator. By rotating the adjusting nut 503 on the leveling screw 502, the four corners of the clamping block 2 are jacked up to make the clamping block 2 in a horizontal state. Then, through the level 203 on the top of the clamping block 2, it is judged whether the clamping block 2 is in a horizontal state;

[0035] After the clamping block 2 is in a horizontal state, the pulling block 402 can be pushed by hand to move the moving plate 4 along the slide bar 302 towards the direction of the through hole b601 until the first indicating needle b701 on one side of the clamping block 2 is aligned with the indicating needle a7. At this time, the piston of the pneumatic actuator is aligned with the center of the through hole b601, and the positioning hole a404 on the pulling block 402 is aligned with the positioning hole b608. Then, the positioning rod 405 is inserted to engage the positioning rod 405 with the positioning hole b608, thereby positioning the clamping block 2. Then, pressure is supplied to the pneumatic actuator to press down the piston, and the piston passes through the through hole a401 and the through hole b601 to apply pressure to the movable plate 602, so that the movable plate 602 moves towards the direction close to the pressure sensor 607 under the limitation of multiple limiting rods 603, and further drives the pressing block 604 at the bottom of the movable plate 602 to squeeze the compression spring 605. The compression spring 605 is stressed and transmits the pressure to the spring seat 606, and then transmits the pressure to the pressure sensor 607 through the spring seat 606. Then, the sensitivity of the pneumatic actuator is obtained through the reaction time of the pressure sensor 607.

[0036] After the detection of the first pneumatic actuator is completed, the pressure supply to it can be stopped to retract the piston. Then, the positioning rod 405 is withdrawn, and the moving plate 4 is continuously pushed to align the second or third indicating needle b701 on one side of the clamping block 2 with the indicating needle a7, and pressure is supplied to perform the sensitivity detection on the second and third pneumatic actuators.

[0037] Among them, the model of the pressure sensor 607 can be YYJ / GY1-1201. The pressure sensor 607 is a common measuring tool that can measure the force or stress received by an object. When an external force acts on the elastic body of the pressure sensor 607, the elastic body will deform, and this deformation will cause a change in the resistance value inside the sensor, thereby reflecting the magnitude of the force. The pressure sensor 607 is a mature and conventional technology in this technical field, and this solution does not make improvements to the circuit or program of the pressure sensor 607. Therefore, the circuit and signal connection relationship of the pressure sensor 607 will not be elaborated.

[0038] In the above embodiments, the descriptions of each embodiment have their own focuses. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0039] The above has introduced in detail a sensitivity detection tooling for a pneumatic actuator provided by an embodiment of the present application. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the technical solution and its core idea of the present application; those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
