Description

Technical Field

[0001] This application relates to the technical field of pneumatic valve testing, and in particular to a testing device for pneumatic valves. Background Technology

[0002] Modern industrial production processes require the extensive use of pneumatic valves, such as seat valves and anti-mixing valves, which utilize air pressure to control the flow and direction of products in pipelines.

[0003] After the pneumatic valve is manufactured, the function of the valve body needs to be tested. Generally, the valve body needs to be fixed on the base, and then the testing machine is fixedly connected to the valve body. The pneumatic valve is then tested multiple times, and the testing machine obtains the final test results. However, the testing process requires multiple clamping and disassembly, which greatly prolongs the testing time and reduces the testing efficiency of the pneumatic valve. Summary of the Invention

[0004] To improve the testing efficiency of pneumatic valves, this application provides a testing device for pneumatic valves.

[0005] This application provides a testing device for a pneumatic valve, which adopts the following technical solution:

[0006] A testing device for a pneumatic valve includes a base, a positioning mechanism mounted on the base, and a clamping mechanism. The positioning mechanism abuts against multiple side walls of the pneumatic valve for positioning. The clamping mechanism includes:

[0007] The fastener is mounted on the base.

[0008] The movable part is slidably mounted on the base in a direction close to or away from the fixed part and is used to connect with the testing machine;

[0009] A drive assembly is used to drive the movable part to slide, so that the fixed part and the movable part abut against multiple side walls of the pneumatic valve and cooperate with the positioning mechanism to position the pneumatic valve and connect it to the testing machine.

[0010] By adopting the above technical solution, the pneumatic valve is placed on the base and positioned against the fixed part. The positioning mechanism is positioned against multiple side walls of the pneumatic valve. Then, the drive component drives the movable part to approach the pneumatic valve, so that the fixed part and the movable part are positioned against multiple side walls of the pneumatic valve. This achieves the positioning of the pneumatic valve. At the same time, the movable part is also used to connect to the testing machine, thereby positioning the pneumatic valve. The pneumatic valve is started, the testing machine is started to perform the test. After the test is completed, the drive component drives the movable part away from the fixed part, and then the pneumatic valve is removed, thus completing the test of the pneumatic valve. This improves the stability and convenience of the test, and improves the test efficiency and effect.

[0011] Optionally, the positioning mechanism includes:

[0012] Two positioning components are slidably mounted on the base, facing each other.

[0013] Two elastic elements are set on the base and connected to two positioning elements respectively, and are used to push the two positioning elements against the opposite side walls of the pneumatic valve for positioning.

[0014] Two actuation components are mounted on the movable part and are used to push the two positioning parts away from each other to facilitate the insertion of the pneumatic valve.

[0015] By adopting the above technical solution, when the moving part moves away from the fixed part to unlock the pneumatic valve, the pushing component drives the two positioning parts to move away from each other, which makes it easier to remove the pneumatic valve after the test is completed and put it back into the pneumatic valve to be tested. Then, the pushing component unlocks the positioning parts, and the two positioning parts move closer to each other and abut against the pneumatic valve under the action of the elastic part for positioning, which improves the stability and convenience of the test, thereby improving the efficiency and effect of the test.

[0016] Optionally, the pushing component includes:

[0017] The push rod is slidably mounted on the movable part along the sliding direction of the movable part and is connected to the positioning part through a connecting assembly;

[0018] A locking element is used to position the push rod and the movable element. The movement of the movable element drives the push rod to move simultaneously. The movement of the two push rods drives the two positioning elements to move away from each other through the connecting assembly. When it is necessary to unlock the positioning elements, the locking element unlocks the push rod and causes the two positioning elements to move closer to each other under the action of the elastic element.

[0019] By adopting the above technical solution, when the moving part approaches the fixed part, the locking part is in the unlocked state, that is, the moving part and the push rod slide against each other without driving the push rod to move. When the moving part and the fixed part clamp the pneumatic valve, the locking part locks the push rod, and then the pneumatic valve is tested.

[0020] After the test is completed, when the moving part moves away from the fixed part, the movement of the moving part drives the push rod to move. The movement of the push rod drives the two positioning parts to move away from each other through the connecting assembly, thereby unlocking the pneumatic valve. After the pneumatic valve is removed and the pneumatic valve under test is placed in it, the locking part unlocks. Under the action of the elastic element, the two positioning parts move closer to each other and press against the pneumatic valve for positioning. At the same time, the movement of the two positioning parts also drives the push rod to move back to its original position through the connecting assembly, which facilitates the subsequent movement of the two positioning parts and improves the testing efficiency and effect of the pneumatic valve.

[0021] Optionally, the connection component includes:

[0022] Connecting block one and connecting block two are set on the positioning component and the push rod, and have connecting surfaces that are mutually attached and inclined. When the movable component moves away from the fixed component, it drives the push rod to move and drives the two positioning components to move away from each other through the connecting surfaces.

[0023] By adopting the above technical solution, the push rod moves through the connecting surface to drive the positioning component, enabling the push rod and the positioning component to move in different directions, thereby improving testing efficiency and effectiveness.

[0024] Optionally, the locking element includes:

[0025] The movable component is set on the active component;

[0026] A connector is mounted on the piston rod of the movable component, and the movable component drives the connector to be inserted into and locked onto the push rod.

[0027] By adopting the above technical solution, the moving part drive connector is plugged into the push rod for positioning, or the moving part drive connector is disengaged from the push rod for unlocking, thereby facilitating the locking and unlocking of the push rod and improving testing efficiency.

[0028] Optionally, both push rods are provided with limiting components to limit the positioning members. When the movable member presses against the pneumatic valve for positioning, the limiting components abut against the two positioning members to lock and prevent the two positioning members from moving away from each other. When the movable member moves away from the pneumatic valve to unlock, it drives the two limiting components to move away from the two positioning members to unlock.

[0029] By adopting the above technical solution, the two positioning components tend to squeeze the elastic component in opposite directions when subjected to force. If the force is greater than the elastic force, it will push the positioning component to move, thereby reducing the positioning effect on the pneumatic valve. In particular, the force is large when the pneumatic valve is running, which further reduces the positioning effect on the pneumatic valve, reduces the accuracy of the test data, and reduces the test effect.

[0030] After the locking component is unlocked, the positioning component drives the push rod and the limit component to move back. The limit component abuts against the positioning component for positioning. After the moving component moves close to the fixed component to position the pneumatic valve, the locking component locks the push rod. Thus, the moving component can lock the two positioning components, which improves the positioning effect of the pneumatic valve and improves the test results.

[0031] Optionally, the limiting component includes:

[0032] Limit block one is set on the positioning component;

[0033] Limiting block two is set on the push rod. Both limiting block one and limiting block two have limiting surfaces that can fit together and be in an inclined state, and are used to position limiting block one.

[0034] By adopting the above technical solution, the positioning component is positioned by the cooperation of the limiting surface. At the same time, the inclined limiting surface can decompose the force of the positioning component into forces in multiple directions, thereby further improving the positioning effect of the positioning component and improving the test results.

[0035] Optionally, the driving component includes:

[0036] A driving component is used to drive the movement of moving parts;

[0037] A pressure detector is mounted on a moving part and is used to detect the pressure exerted by the pneumatic valve on the moving part and is electrically connected to the drive part.

[0038] By adopting the above technical solution, the driving component drives the moving component and the pressure detector to move. The moving component abuts against the pneumatic valve for positioning, and the pressure detector detects the pressure on the pneumatic valve. When the pressure reaches the specified value, the driving component stops moving to perform positioning. Therefore, it is easy to clamp pneumatic valves of different sizes, which improves the positioning effect of pneumatic valves of various sizes.

[0039] Optionally, clamping members are detachably provided on the opposite side walls of the fixed member and the movable member via connecting members, and the clamping members are used to clamp and position the pneumatic valve.

[0040] By adopting the above technical solution and replacing different clamping components, pneumatic valves of different sizes can be clamped, thus improving the applicability of this structure.

[0041] Optionally, the connector is a trapezoidal block, which is mounted on the clamping member and snapped onto the fixed or movable member for positioning.

[0042] By adopting the above technical solution, the connecting blocks and fixed or moving parts are plugged in, making disassembly and assembly extremely convenient. At the same time, the trapezoidal connecting blocks also improve the stability after connection.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. The pneumatic valve is positioned by placing it on the base and abutting against the fixed part. The positioning mechanism abuts against multiple side walls of the pneumatic valve for positioning. The drive component drives the movable part to approach the pneumatic valve, thereby cooperating with the fixed part to position the pneumatic valve. At the same time, the movable part is also used to connect to the testing machine. The pneumatic valve is started for testing. After the test is completed, the drive component drives the movable part away from the fixed part, and then the pneumatic valve is removed, thus completing the test of the pneumatic valve. This improves the stability and convenience of the test, and enhances the test efficiency and effect.

[0045] 2. When the pneumatic valve is unlocked by moving the movable part away from the fixed part, the push assembly drives the two positioning parts to move away from each other, which makes it easier to remove the pneumatic valve after the test is completed and put it back into the pneumatic valve under test. Then, push the assembly to unlock the positioning parts. The two positioning parts move closer to each other and abut against the pneumatic valve under the action of the elastic part for positioning, which improves the stability and convenience of the test, thereby improving the efficiency and effect of the test.

[0046] 3. After unlocking via the locking component, the positioning component drives the push rod and the limit component to move back. The limit component abuts against the positioning component for positioning. After the moving component moves close to the fixed component to position the pneumatic valve, the locking component locks the push rod. Thus, the moving component can lock the two positioning components, improving the positioning effect of the pneumatic valve and improving the test results. Attached Figure Description

[0052] The following provides a further detailed description of this application.

[0053] This application discloses a testing device for pneumatic valves.

[0054] Reference Figure 1The testing device for a pneumatic valve includes a base 1, a positioning mechanism 4 and a clamping mechanism 2 mounted on the base 1. The positioning mechanism 4 abuts against the opposite side walls of the pneumatic valve for positioning, and the clamping mechanism 2 clamps and positions the pneumatic valve against the opposite side walls. Simultaneously, the positioning mechanism 4 and the clamping mechanism 2 can clamp and position the side walls of the pneumatic valve in four directions. The pneumatic valve is placed on the base 1, the positioning mechanism 4 abuts against the opposite side walls of the pneumatic valve for positioning, and then the clamping mechanism 2 is activated to clamp and position the pneumatic valve against the opposite side walls, thereby connecting the pneumatic valve to the testing machine to perform testing on the pneumatic valve.

[0055] The clamping mechanism 2 includes a fixed member 21, a movable member 22, and a drive assembly 3. The fixed member 21 is fixedly installed on the upper surface of the base 1, and the movable member 22 is slidably installed on the upper surface of the base 1 in a direction close to or away from the fixed member 21. The drive assembly 3 is used to drive the movable member 22 to slide, so that the fixed member 21, the movable member 22, and the positioning mechanism 4 cooperate to clamp and position the pneumatic valve, and the side wall of the pneumatic valve in contact with the fixed member 21 and the movable member 22 and the side wall of the pneumatic valve in contact with the positioning mechanism 4 are perpendicular to each other. A test structure can be fixedly installed on the movable member 22 according to the test requirements. The test structure is fixedly installed with wires that are electrically connected to the test machine, thereby realizing the testing of various parameters of the pneumatic valve. The test structure is set according to different test requirements, which will not be described in detail here.

[0056] Reference Figure 1 and Figure 2 The drive assembly 3 includes a drive component 31 and a pressure detector 32. The movable component 22 has a mounting groove 29 on its side wall near the fixed component 21. The drive component 31 is an electric actuator, etc., and is fixedly mounted on the upper surface of the base 1. The piston rod of the drive component 31 is fixedly connected to the movable component 22. A control box for controlling the start and stop of the electric actuator is fixedly mounted on the base 1. The pressure detector 32 is fixedly mounted in the mounting groove 29, and the detection element of the pressure detector 32 extends to the outside of the mounting groove 29. The pressure detector 32 is electrically connected to the control box. When the movable component 22 presses against the side wall of the pneumatic valve for positioning, the pressure detector 32 is used to detect the pressure. When the pressure reaches a specified value, the control box controls the drive component 31 to stop moving and positions the movable component 22.

[0057] Two positioning mechanisms 4 are spaced apart. Each positioning mechanism 4 includes a positioning element 41, an elastic element 42, and a pushing component 5. The two positioning elements 41 are horizontally slidably mounted on the upper surface of the base 1, and are positioned close to or far from each other. The sliding direction of the positioning elements 41 is perpendicular to the sliding direction of the movable element 22. Simultaneously, the spaced-apart directions of the fixed element 21 and the movable element 22 are perpendicular to the spaced-apart directions of the two positioning elements 41. Two fixed blocks 43 are fixedly mounted at intervals on the upper surface of the base 1. The two positioning elements 41 are located between the two fixed blocks 43. The elastic element 42 is a spring, and the two elastic elements 42 are correspondingly arranged with the two positioning elements 41. The elastic elements 42 are fixedly mounted on the sidewalls of the fixed blocks 43 and the positioning elements 41 on opposite sides, and are used to push the two positioning elements 41 to maintain a tendency to move closer together.

[0058] Reference Figure 1 , Figure 3 Two pushing components 5 are mounted on the movable part 22 and connected to two positioning parts 41 respectively. The pushing components 5 are used to push the two positioning parts 41 away from each other to facilitate the insertion of the pneumatic valve. The pushing components 5 include a pushing rod 51 and a locking member 52. The pushing rod 51 slides along the sliding direction of the movable part 22 and passes through the movable part 22. Both pushing rods 51 are connected to the two positioning parts 41 through connecting components 6. The two locking members 52 are used to position the two pushing rods 51 respectively.

[0059] Reference Figure 1 , Figure 4 The movable part 22 has a sliding hole 27 for the push rod 51 to slide. The upper surface of the movable part 22 has a moving hole 28 communicating with the sliding hole 27 in the vertical direction. The locking part 52 includes a movable part 53 and a plug-in part 54. The movable part 53 is an electric push rod. The movable part 53 is fixedly installed on the upper surface of the movable part 22, and the piston rod of the movable part 53 extends vertically downward into the moving hole 28. The plug-in part 54 is slidably installed on the moving hole 28 and fixedly installed on the piston rod of the movable part 53. The movable part 53 drives the plug-in part 54 to be inserted into the push rod 51 for positioning, thereby realizing the unlocking and locking of the push rod 51.

[0060] Both push rods 51 are provided with limiting components 7 to limit the two positioning parts 41. When the movable part 22 presses against the pneumatic valve for positioning, the limiting components 7 abut against the two positioning parts 41 to lock and prevent the two positioning parts 41 from moving away from each other. When the movable part 22 moves away from the pneumatic valve to unlock, it drives the two limiting components 7 to move away from the two positioning parts 41 to unlock.

[0061] Reference Figure 1 , Figure 3The connecting component 6 includes a first connecting block 61 and a second connecting block 62. The first connecting block 61 is fixedly installed on the side wall of the positioning member 41 near the push rod 51. The second connecting block 62 is fixedly installed on the end of the push rod 51 near the positioning member 41. The second connecting block 62 is located on the side of the first connecting block 61 away from the fixed block 43, that is, the two second connecting blocks 62 are located between the two first connecting blocks 61. The first connecting block 61 and the second connecting block 62 are provided with a connecting surface 63 that fits against each other and is inclined. The push rod 51 drives the second connecting block 62 away from the positioning member 41. The second connecting block 62 pushes the first connecting block 61 and the positioning member 41 to move through the connecting surface 63, thereby realizing that the two positioning members 41 move away from each other.

[0062] The limiting component 7 includes a first limiting block 71 and a second limiting block 72. The first limiting block 71 is fixedly installed on the side wall of the positioning member 41 near the push rod 51, and the first limiting block 71 is located on the side of the connecting block 61 near the fixing block 43, that is, the two connecting blocks 61 are located between the two first limiting blocks 71. The second limiting block 72 is fixedly installed on the end of the push rod 51 near the positioning member 41, and the second limiting block 72 is located on the side of the first limiting block 71 away from the connecting block 61, that is, the two first limiting blocks 71 are located between the two second limiting blocks 72. The first limiting block 71 and the second limiting block 72 are provided with mutually fitting and inclined limiting surfaces 73, and the limiting surfaces 73 and the connecting surfaces 63 are parallel to each other. The movable member 22 positions the push rod 51 and the second connecting block 62. The second connecting block 62 positions the first connecting block 61 and the positioning member 41 through the connecting surface 63, thereby enabling the positioning of the two positioning members 41.

[0063] Reference Figures 1-3 The driving component 31 drives the movable component 22 away from the fixed component 21. The movable component 22 moves and drives the push rod 51 away from both the fixed component 21 and the positioning component 41. The push rod 51 drives the connecting block 2 62 and the connecting block 1 61 to move, pushing the two positioning components 41 away from the pneumatic valve. This unlocks the pneumatic valve by the fixed component 21, the movable component 22, and the two positioning components 41. After the pneumatic valve is removed and the test is completed, the pneumatic valve to be tested is placed in. The locking component 52 unlocks, and the two positioning components 41 move back under the action of the elastic component 42 and press against the pneumatic valve for positioning. The return movement of the positioning component 41 drives the connecting block 2 62, the limiting block 2 72, and the push rod 51 to move back. Then, the movable component 22 moves back, causing the movable component 22 and the fixed component 21 to press against the pneumatic valve for positioning. The locking component 52 positions the push rod 51. Therefore, the two positioning components 41 can be positioned, thereby improving the testing efficiency and effect.

[0064] Reference Figure 1 , Figure 4Clamping parts 25 are detachably installed on the opposite side walls of the fixed part 21 and the opposite side walls of the two positioning parts 41 via connecting parts. The four clamping parts 25 work together to clamp and position the pneumatic valve, so that clamping parts 25 that are adapted to the size and / or shape of the pneumatic valve can be replaced as needed, thereby improving the testing efficiency and effect of different pneumatic valves.

[0065] The following explanation uses the connector located at the fixing member 21 as an example. The fixing member 21 has a connecting groove 23 on the side wall near the positioning member 41, which communicates with the top of the fixing member 21. The vertical projection of the connecting groove 23 is trapezoidal. The connector is a trapezoidal connecting block 24. The connecting block 24 is fixedly installed on the side wall of the clamping member 25 near the fixing member 21. The connecting block 24 is inserted into the connecting groove 23 from top to bottom for positioning, thereby realizing the installation of the clamping member 25.

[0066] The working principle of this application embodiment is as follows:

[0067] The driving component 31 drives the movable component 22 away from the fixed component 21. The movable component 22 moves and drives the two positioning components 41 away from the pneumatic valve, thereby unlocking the pneumatic valve by the fixed component 21, the movable component 22, and the two positioning components 41. Then, the pneumatic valve that has been tested is removed and the pneumatic valve to be tested is placed in it, so that the pneumatic valve is positioned against the fixed component 21. The locking component 52 is unlocked, and the two positioning components 41 move back and press against the pneumatic valve for positioning. The return movement of the positioning components 41 drives the connecting block 62 and the limiting block 72 and the push rod 51 to move back. Then, the movable component 22 moves back to position the pneumatic valve, and the locking component 52 positions the push rod 51. Therefore, the two positioning components 41 can be positioned, thereby improving the testing efficiency and effect.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
