Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic actuators, in particular to a pneumatic actuator testing device. Background Art

[0002] Pneumatic actuators are commonly known as pneumatic heads and are also called pneumatic actuators. Actuators are divided into three categories according to their energy forms: pneumatic, electric and hydraulic. They have their own characteristics and are suitable for different occasions. Pneumatic actuators are a category of actuators. The actuator and regulating mechanism of pneumatic actuators are a unified whole. Its actuators include diaphragm type, piston type, scotch fork type and gear rack type. The piston type has a long stroke and is suitable for occasions requiring a large thrust; while the diaphragm type has a small stroke and can only directly drive the valve stem. The scotch fork type pneumatic actuator has the characteristics of large torque, small space, and a torque curve that is more in line with the torque curve of the valve, but it is not very beautiful; it is often used on valves with large torque. The gear rack type pneumatic actuator has the advantages of simple structure, smooth and reliable action, and safety and explosion-proof. It is widely used in power plants, chemical industry, oil refining and other production processes with high safety requirements.

[0003] However, it still has some disadvantages. For example, when using a pneumatic actuator for testing, it is not convenient to fix the pneumatic actuator, so a fixing frame is often required for testing. At the same time, different fixing frames are used when testing different pneumatic actuators, which is very inconvenient to use. In addition, due to the vibration generated during the test, the test results are inaccurate, which has a great impact on the test and often takes a long time.

[0004] In order to solve the above problems, the present application proposes a pneumatic actuator testing device. Utility Model Content

[0005] The utility model aims to provide a pneumatic actuator testing device to solve the problems in the prior art proposed in the background art that the fixing device during the pneumatic actuator testing cannot be universally applied to most pneumatic actuators and the vibration leads to inaccurate test results.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pneumatic actuator testing device, comprising a detection box, the upper outer surface of the detection box is detachably connected to a fixed clamp, a pneumatic actuator is placed on the upper outer surface of the detection box, a cylinder is provided on the outer wall of the pneumatic actuator, and a support ring is fixedly connected to the outer surface of one side of the pneumatic actuator.

[0007] Preferably, a shock-absorbing bottom column is fixedly connected to the lower outer surface of the detection box, a clamping plate groove is provided on the upper outer surface of the detection box, and detection holes are provided on the upper outer surface of the detection box, and the detection holes are provided in ten groups.

[0008] Preferably, both sides of the outer surface of the lower end of the fixed splint are fixedly connected with splint inserts, one side of the outer surface of the fixed splint is movably sleeved with a screw column, and the other side of the screw column is movably sleeved with a soft cushion.

[0009] Preferably, a rotating ring is fixedly connected to an outer surface of one side of the screw column, and a manual crank is fixedly connected to an outer surface of one side of the rotating ring.

[0010] Preferably, a fixing pad is fixedly connected to the outer surface of the upper end of the shock-absorbing base column.

[0011] Preferably, a telescopic spring column is fixedly connected to the outer surface of the upper end of the fixed pad, a compression spring is movably sleeved on the outer wall of the telescopic spring column, and a top pad is fixedly connected to the outer surface of the upper end of the telescopic spring column.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a fixed clamping plate, and when using the test device, since it is inconvenient to use the test, the clamping plate is inserted into the clamping plate groove for fixing during the test, and the pneumatic actuator is placed in the middle. Before use, the hand crank is shaken so that the rotating circle drives the screw column thread to rotate closer and closer to the inside. At the same time, the soft pad on the other side of the screw column is used so as not to damage the pneumatic actuator, so that it is convenient for it to squeeze and fix the pneumatic actuator. The utility model can be suitable for most pneumatic actuators.

[0014] The utility model provides a shock-absorbing bottom column, on which a fixed pad is fixedly connected, so that the compression spring whose telescopic spring column is movably sleeved with the outer wall can stably work on the outer surface of the upper end of the shock-absorbing bottom column. When vibration occurs, the elastic movement generated by the compression spring and the telescopic spring column can reduce most of the impact of vibration.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a pneumatic actuator testing device, including a detection box 1, the upper outer surface of the detection box 1 is detachably connected with a fixed clamp 2, a pneumatic actuator 3 is placed on the upper outer surface of the detection box 1, a cylinder 4 is opened on the outer wall of the pneumatic actuator 3, and a support ring 5 is fixedly connected to the outer surface of one side of the pneumatic actuator 3. The pneumatic actuator 3 is placed on the detection box 1 through the setting of the detection box 1, and the detection hole 8 and the cylinder 4 are connected by a pipeline, so that the cylinder data results are very convenient to use.

[0022] In this embodiment, Figure 2-3 As shown, the lower outer surface of the detection box 1 is fixedly connected with a shock-absorbing bottom column 6, the upper outer surface of the detection box 1 is provided with a clamping plate groove 7, the upper outer surface of the detection box 1 is provided with a detection hole 8, and there are ten groups of detection holes 8. The lower outer surface of the fixed clamp 2 is fixedly connected with a clamping plate plug 9 on both sides, and the outer surface of one side of the fixed clamp 2 is movably sleeved with a screw column 11, and the other side of the screw column 11 is movably sleeved with a soft cushion 10, and the outer surface of one side of the screw column 11 is fixedly connected with a rotating circle 12, and the outer surface of one side of the rotating circle 12 is fixedly connected with a manual crank 13. Through the setting of the fixed clamp Plate 2, when using the test device, because the test is inconvenient to use, the fixed splint 2 is set up. When testing, the splint insert plate 9 is inserted into the splint groove 7 for fixing, and the pneumatic actuator 3 is placed in the middle. Before use, the hand crank 13 will be shaken to make the rotating circle 12 drive the screw column 11 thread to rotate closer and closer to the inside. At the same time, the soft pad 10 on the other side of the screw column 11 is used so as not to damage the pneumatic actuator 3. It is convenient for it to squeeze and fix the pneumatic actuator 3, which can be suitable for most pneumatic actuators 3 of different sizes.

[0023] In this embodiment, Figure 4As shown, a fixed pad 14 is fixedly connected to the outer surface of the upper end of the shock-absorbing bottom column 6, and a telescopic spring column 15 is fixedly connected to the outer surface of the upper end of the fixed pad 14. A compression spring 16 is movably sleeved on the outer wall of the telescopic spring column 15, and a top pad 17 is fixedly connected to the outer surface of the upper end of the telescopic spring column 15. Through the arrangement of the shock-absorbing bottom column 6, a fixed pad 14 is fixedly connected to the shock-absorbing bottom column 6, so that the telescopic spring column 15 and the compression spring 16 movably sleeved on the outer wall can stably work on the outer surface of the upper end of the shock-absorbing bottom column 6. When vibration occurs, the elastic movement generated by the compression spring 16 and the telescopic spring column 15 can reduce most of the influence of vibration, thereby avoiding inaccurate detection results of the detection box 1. At the same time, the top pad 17 is at the top to avoid spring disorder and falling off.

[0024] Working principle:

[0025] When using the detection box 1, the clamping plate 9 is inserted into the clamping plate groove 7 for fixing, and the pneumatic actuator 3 is placed in the middle. Before use, the manual crank handle 13 is shaken to make the rotating circle 12 drive the screw column 11 to rotate closer and closer to the inside. At the same time, the soft pad 10 on the other side of the screw column 11 is used to squeeze and fix the pneumatic actuator 3 in order not to damage the pneumatic actuator 3. The soft pad 10 is used to facilitate its squeezing and fixing of the pneumatic actuator 3, which can be suitable for most pneumatic actuators 3. The manual crank handle 13 is shaken according to the size of the pneumatic actuator 3 to squeeze and fix it. During use, vibration will be generated, which will cause the measured data to change and become inaccurate. A fixed pad 14 is fixedly connected to the shock-absorbing bottom column 6, so that the compression spring 16 that is movably sleeved with the telescopic spring column 15 and the outer wall can stably work on the outer surface of the upper end of the shock-absorbing bottom column 6. When vibration occurs, the elastic movement generated by the compression spring 16 and the telescopic spring column 15 can reduce most of the impact of vibration, avoiding inaccurate detection results of the detection box 1. At the same time, the top pad 17 is at the top to avoid spring disorder and falling off, thereby greatly improving the accuracy of the test data.

[0026] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
