Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, and more specifically, it relates to a pneumatic actuator clamping device. Background Technology

[0002] A pneumatic actuator is an actuating device that uses air pressure to open, close, or regulate valves. It is also called a pneumatic actuator mechanism or pneumatic device, but is commonly referred to as a pneumatic head. Pneumatic actuators are sometimes equipped with auxiliary devices. Commonly used ones include valve positioners and handwheel mechanisms. The function of a valve positioner is to use the feedback principle to improve the performance of the actuator, enabling it to achieve accurate positioning according to the control signal from the controller. The function of a handwheel mechanism is to directly operate the control valve to maintain normal production when the control system is affected by power outages, air supply interruptions, controller output failure, or actuator malfunction.

[0003] To facilitate the testing of pneumatic actuators, our company developed a testing fixture, publication number CN218285206U, which uses two sets of adjustable clamping components to clamp the pneumatic actuator. However, the device has the following problems in subsequent operation: 1. The two clamping components are positioned by positioning slots, but the distance between two adjacent positioning slots is constant, which makes it impossible to flexibly adjust the distance between the two clamping components.

[0004] 2. In order to meet the current market demand, the structures at both ends of the actuator are different, and this clamping assembly cannot meet all the actuator fixing requirements. Utility Model Content

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0027] Reference Figures 1 to 4 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a pneumatic actuator clamping device, comprising a base 1, a fixing component 2 and an adjusting component 3, wherein the fixing component 2 and the adjusting component 3 are respectively installed on both sides of the base 1, and a clamping area 11 for placing the pneumatic actuator is formed between the fixing component 2 and the adjusting component 3.

[0028] Both the adjustment component 3 and the fixing component 2 include a mounting base 21, an upper adjustment base 22, and a side adjustment plate 23. Two sets of side adjustment plates 23 are provided and can be detachably installed on both sides of the mounting base 21. The two side adjustment plates 23 and the mounting base 21 together form an installation area for the upper adjustment base 22 to be installed.

[0029] The adjustment component 3 also includes a drive element 31 for moving the corresponding mounting base 21.

[0030] In this invention, the drive component 31 is electrically controlled, and the drive source can be an electric cylinder or a motor, which is connected to an external controller.

[0031] The drive component 31 is moved by an external controller, and the movement distance is unlimited, so that the gap between the fixed component 2 and the adjusting component 3 can be precisely adjusted to meet the fixing requirements of pneumatic actuators of different sizes.

[0032] Furthermore, by replacing the upper adjusting seat 22 and the side adjusting plate 23, different clamping surfaces can be formed to correspond to the end faces of different pneumatic actuators, thereby improving the flexibility of the equipment.

[0033] For example, some pneumatic actuators have flat end faces and others have curved end faces. In this case, the limit fixation requirement can be achieved by replacing different upper adjustment seats 22.

[0034] By replacing different side adjustment plates 23, different sizes of installation areas can be formed with the mounting base 21 to meet the installation requirements of upper adjustment bases 22 of different sizes.

[0035] The present invention is further configured such that: two sets of guide grooves 12 are provided on the base 1 along its length direction, and two guide blocks 211 are provided at the bottom of the mounting base 21, and the guide blocks 211 are slidably connected in the guide grooves 12.

[0036] The design of this structure, such as Figure 1 As shown, the mounting base 21 of the adjustment component 3 is slidably connected to the guide groove 12 through the guide block 211, and the guide groove 12 ensures the stability of the sliding of the mounting base 21.

[0037] Adjustment component 3 is a sliding installation, while fixing component 2 is a fixed installation. Multiple installation positions can be set according to requirements, thereby allowing adjustment of the installation position of fixing component 2. Fixing component 2 can be installed using conventional threaded installation.

[0038] The present invention is further configured such that: the driving component 31 includes a driving motor 32, a lead screw 33 and a guide rod 34, the lead screw 33 is installed in a guide groove 12 and the guide rod 34 is installed in another guide groove 12;

[0039] Drive motor 32 is used to drive lead screw 33 to rotate;

[0040] One guide block 211 is screwed to the lead screw 33, and the other guide block 211 is slidably engaged with the guide rod 34.

[0041] The design of this structure adopts the principle of lead screw 33 transmission. The lead screw 33 is driven to rotate by the drive motor 32. At this time, with the cooperation of a guide block 211 and lead screw 33, it can slide along the guide rod 34, thereby realizing the adjustment of the clamping area 11.

[0042] The present invention is further configured such that: the upper end of the mounting base 21 is provided with a mounting surface 212, the mounting surface 212 is provided with a plurality of positioning holes 213 along its length direction, and the upper adjusting base 22 is provided with a connecting hole 221 through it, the connecting hole 221 being connected to the positioning hole 213 by a connecting bolt.

[0043] The design of this structure allows for a detachable connection between the upper adjustment seat 22 and the base 1 via connecting bolts. When the connecting hole 221 is connected to different positioning holes 213, the position of the upper adjustment seat 22 can be changed, so that the end face of the upper adjustment seat 22 forms a convex, flat, or concave shape with the end face of the mounting seat 21 and the side adjustment plate 23, thereby forming different clamping surfaces to accommodate individual pneumatic actuators.

[0044] The mounting surface 212 is set at an angle. The upper adjustment seat 22 is slidably connected to the mounting surface 212. The positioning hole 213 includes a first positioning hole 213 and a second positioning hole 213. When the connecting hole 221 is aligned with the first positioning hole 213, one end of the upper adjustment seat 22 is flush with one end of the side adjustment plate 23.

[0045] When the connecting hole 221 is aligned with the second positioning hole 213, one end of the upper adjusting seat 22 extends beyond one end of the side adjusting plate 23.

[0046] Based on the improved structure described above, this structure is mainly used to form a convex or flat shape to meet the limiting function of most pneumatic actuators.

[0047] This utility model is further configured such that: both ends of the mounting base 21 are provided with mounting holes 214, and the side adjusting plate 23 is provided with a positioning rod 231 for insertion into the mounting holes 214, and the positioning rod 231 is provided with a threaded hole 232. In this design, the positioning rod 231 is first inserted into the mounting hole 214 for fixation, and then a bolt is inserted into the threaded hole 232 to fix both.

[0048] The present invention is further configured such that: a guide portion 233 is inclinedly provided on the inner side of the side adjusting plate 23, and sliding grooves 222 that cooperate with the guide portion 233 are provided on both sides of the upper adjusting seat 22. Figure 4 As shown, the design of this structure can improve the stability of the sliding of the upper adjustment seat 22.

[0049] The present invention is further configured such that an indicator is provided at the upper end of the base 1.

[0050] The design of this structure allows the indicator to be a scale line set on the base 1, which is used to indicate the size of the clamping area 11, making the operation process more intuitive.

[0051] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
