Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic actuator preparation, in particular to a special quick fastening device for pneumatic actuator preparation. Background Art

[0002] A pneumatic actuator is a device that uses air pressure to open, close, or regulate valves. It's also called a pneumatic actuator or pneumatic device, but more commonly referred to as a pneumatic head. Pneumatic actuators are sometimes equipped with auxiliary devices, most commonly valve positioners and handwheel mechanisms. A valve positioner utilizes feedback to improve actuator performance, enabling the actuator to accurately position according to the controller's control signals. The handwheel mechanism allows for direct control of the control valve to maintain normal production when the control system experiences a power outage, gas outage, controller failure, or actuator failure.

[0025] The utility model provides a technical solution:

[0026] Example 1

[0027] Combine Figures 1 to 4 A special quick fastening device for preparing a pneumatic actuator includes a base 3, a driving mechanism 1 is provided on the top of the base 3, and a fixing mechanism 2 is provided in the driving mechanism 1.

[0028] The driving mechanism 1 includes a supporting assembly 11, a driving assembly 12, a transmission assembly 13 and an adjusting assembly 14. The supporting assembly 11 is arranged on the top of the base 3, the driving assembly 12 is arranged on the top of the supporting assembly 11, the transmission assembly 13 is arranged on the front and rear sides of the driving assembly 12, and the adjusting assembly 14 is fixedly connected to the bottom of the transmission assembly 13.

[0029] The support assembly 11 includes a support frame 1101, which is fixedly connected to the top of the base 3. The top of the inner side of the support frame 1101 is fixedly connected to a connecting frame 1102. The drive assembly 12 includes a dual-axis motor 1201, which is fixedly connected to the top of the support frame 1101. The front and rear sides of the dual-axis motor 1201 are fixedly connected to a rotating shaft 1202. The outer ring of the rotating shaft 1202 is rotatably connected to a supporting rotating frame 1203. The supporting rotating frame 1203 is fixedly connected to the top of the support frame 1101. The transmission assembly 13 includes a bevel gear 1301, which is fixedly connected to the rotating shaft 1202. On the outside, the bottom of the outer ring of bevel gear 1301 is meshed with bevel gear 2 1302, and the inner ring of bevel gear 2 1302 is fixedly connected to the rotating shaft 1303, and the rotating shaft 1303 is rotatably connected to the top of the support frame 1101. The adjustment component 14 includes a two-handed threaded rod 1401, which is fixedly connected to the bottom of the rotating shaft 1303. The bottom of the two-handed threaded rod 1401 is rotatably connected to the clamping shaft 1402, and the clamping shaft 1402 is fixedly connected to the top of the base 3. The middle of the outer ring of the two-handed threaded rod 1401 is rotatably connected to the support rotating frame 2 1403, and the support rotating frame 2 1403 is fixedly connected to the front and back sides of the support frame 1101.

[0030] Furthermore: the staff only needs to start the dual-axis motors 1201 on the left and right sides to control the V-shaped splint 1 2102 and the V-shaped splint 2 2202 on the upper and lower sides to move outward synchronously, so that the inner end angle of the V-shaped splint 1 2102 and the V-shaped splint 2 2202 completes the fixing of the pneumatic actuator. The operation is simple and convenient for the staff to use.

[0031] Example 2

[0032] See Figure 1 and Figure 4 , and on the basis of Example 1, it is further obtained that the fixing mechanism 2 includes a first clamping component 21 and a second clamping component 22, the first clamping component 21 is arranged on the outer ring of the adjusting component 14, and the second clamping component 22 is arranged above the outer ring of the adjusting component 14 and the first clamping component 21.

[0033] The first clamping assembly 21 includes a first threaded barrel 2101, which is threadedly connected to the bottom of the outer ring of the two-handed threaded rod 1401, and the outer ring of the first threaded barrel 2101 is fixedly connected to a V-shaped clamp 2102. The second clamping assembly 22 includes a second threaded barrel 2201, which is threadedly connected to the top of the outer ring of the two-handed threaded rod 1401, and the inner side of the outer ring of the second threaded barrel 2201 is fixedly connected to a V-shaped clamp 2202, and the V-shaped clamp 2202 is slidably connected to the inside of the V-shaped clamp 2102.

[0034] Furthermore: the V-shaped clamp 1 2102 and the V-shaped clamp 2 2202 cooperate to complete the fixation through the four-point contact between the inner sides of the V-shaped clamp 1 2102 and the V-shaped clamp 2 2202 and the outer ring of the pneumatic actuator. Compared with the existing common two-way clamping, the stability of the pneumatic actuator after fixation is increased. At the same time, the angle between the inner ends of the V-shaped clamp 1 2102 and the V-shaped clamp 2 2202 is gradually reduced, so that when the V-shaped clamp 1 2102 and the V-shaped clamp 2 2202 cooperate to clamp, pneumatic actuators of different diameters and shapes can be fixed as they move. The shape of the pneumatic actuator itself is not required to be high, which increases the scope of application of the device when used. The V-shaped clamp 1 2102 and the V-shaped clamp 2 2202 only need to move synchronously to complete the fixation of the pneumatic actuator. The operation is simple, so that the staff can quickly complete the fixation of the pneumatic actuator.

[0035] In actual operation, when this device is used, the staff first places the pneumatic actuator that needs to be fixed on the inner side of the V-shaped clamp plate 2202, so that the bottom of the pneumatic actuator fits with the inner bottom of the V-shaped clamp plate 2202. Then the staff starts the dual-axis motor 1201, and the dual-axis motor 1201 starts to drive the bevel gear 1301 to rotate through the rotating shaft 1202. The rotation of the bevel gear 1301 drives the rotating shaft 1303 to rotate through the bevel gear 2 1302. The rotation of the rotating shaft 1303 drives the double-handed threaded rod 1401 to rotate. The double-handed threaded rod 1401 rotates. The rotation of 401 drives the first threaded cylinder 2101 and the second threaded cylinder 2201 on the upper and lower sides to move outward synchronously. The outward movement of the first threaded cylinder 2101 drives the V-shaped clamping plate 2202 to move upward, and the outward movement of the second threaded cylinder 2201 drives the V-shaped clamping plate 1 2102 to move downward until the inner top of the V-shaped clamping plate 1 2102 fits with the top of the outer ring of the pneumatic actuator, and the two-handed threaded rod 1401 can no longer rotate to drive the first threaded cylinder 2101 and the second threaded cylinder 2201 on the upper and lower sides to move. At this time, the fixing work of the pneumatic actuator is completed.

[0036] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.
