Abstract
Description
Technical Field
[0001] This utility model relates to a clamping device, specifically a positioning clamping device for assembling pneumatic actuators. Background Technology
[0002] A pneumatic actuator is an actuating device that uses air pressure to open, close, or regulate a valve. It is also called a pneumatic actuator mechanism or pneumatic device, and its structure is as follows: Figure 1 As shown, the pneumatic actuator body 110 is included. Both the upper and lower ends of the pneumatic actuator body 110 need to be fitted with end caps 120. In actual installation, the screws need to be tightened into the screw holes 130 provided on the end caps 120 to achieve a fastening between the end caps 120 and the pneumatic actuator body 110. However, since there is a spring installed between the end caps 120 and the pneumatic actuator body 110, if the end caps 120 are not pressed onto the pneumatic actuator body 110 first and the screws are tightened directly, there is not only a risk that the screws will not be tightened properly, the assembly quality cannot be guaranteed, and the efficiency of tightening the screws will be reduced. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model proposes a positioning and clamping device for assembling pneumatic actuators, which can improve the assembly efficiency and effect between the pneumatic actuator body and the end cap.
[0004] To achieve the above technical solution, this utility model provides a positioning and clamping device for assembling pneumatic actuators, comprising: a base, on which four long, rectangular, and upwardly extending support rods are mounted, a top plate is fixed to the top of the four support rods, a pressing mechanism is mounted at the bottom of the top plate and is vertically downward, a pressure plate is mounted on the telescopic shaft of the pressing mechanism, the front end of the pressure plate is T-shaped and extends horizontally forward, and a limiting seat is mounted on the base below the pressure plate, the front end of the limiting seat is provided with a limiting groove.
[0005] In the above technical solution, during actual operation, simply place the pneumatic actuator body on the base and embed the back of the pneumatic actuator body into the limiting groove set at the front end of the limiting seat to stabilize the position of the pneumatic actuator body. Then, place the spring and end cap on top of the pneumatic actuator body in sequence. Then, activate the pressing mechanism to push the pressure plate down, so that the T-shaped protrusion at the front end of the pressure plate overcomes the elastic force of the spring and presses the end cap tightly onto the pneumatic actuator body. Then, screws are screwed into the screw holes set on the surface of the end cap by manual or mechanical means to achieve the fastening between the end cap and the pneumatic actuator body.
[0006] Preferably, the positioning and clamping device further includes a foot pedal controller, which is electrically connected to the control switch of the pressing mechanism. In actual operation, the foot pedal controller can control the start and stop of the pressing mechanism, which can free the operator's hands and improve the efficiency of alignment and screw tightening.
[0007] Preferably, the pressing mechanism is a pneumatic cylinder or a hydraulic cylinder, and the appropriate type can be selected according to the user's needs during actual operation.
[0008] The advantages of the positioning and clamping device for assembling pneumatic actuators provided by this utility model are as follows: This positioning and clamping device for assembling pneumatic actuators has a simple structure, reasonable design, and convenient operation. In actual operation, simply place the pneumatic actuator body on the base, and embed the back of the pneumatic actuator body into the limiting groove set at the front end of the limiting seat to stabilize the position of the pneumatic actuator body. Then, place the spring and end cap on the top of the pneumatic actuator body in sequence, and then activate the pressing mechanism to push the pressure plate down, so that the T-shaped protrusion at the front end of the pressure plate overcomes the elastic force of the spring and presses the end cap tightly onto the pneumatic actuator body. Then, screws are screwed into the screw holes set on the surface of the end cap by manual or mechanical means to achieve the fastening between the end cap and the pneumatic actuator body, thereby improving the assembly efficiency and assembly effect between the pneumatic actuator body and the end cap.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0014] Example: A positioning and clamping device for assembling pneumatic actuators.
[0015] Reference Figures 1 to 3As shown, a positioning and clamping device for assembling a pneumatic actuator includes: a base 1, on which four long, rectangular, and upwardly extending support rods 2 are mounted; a top plate 3 is fixed to the top of the four support rods 2; a pressing mechanism 4 is mounted at the bottom of the top plate 3 and is vertically downward; the pressing mechanism 4 is either a pneumatic cylinder or a hydraulic cylinder, which can be selected according to the user's needs during actual operation; a pressure plate 5 is mounted on the telescopic shaft of the pressing mechanism 4; the front end of the pressure plate 5 is T-shaped and extends horizontally forward; setting the front end of the pressure plate 5 to T-shape and extend horizontally forward facilitates pressing the middle part of the pneumatic actuator body 110 and avoids exposing the screw holes 130 on the end cover 120, thereby facilitating screw insertion; a limiting seat 6 is mounted on the base 1 below the pressure plate 5; the front end of the limiting seat 6 is provided with a limiting groove. This positioning and clamping device also includes a foot pedal controller, which is electrically connected to the control switch of the pressing mechanism 4. In actual operation, the foot pedal controller can control the start and stop of the pressing mechanism 4, which can free the operator's hands and improve the efficiency of alignment and screw tightening.
[0016] The positioning and clamping device for assembling pneumatic actuators has a simple structure, reasonable design, and convenient operation. In actual operation, simply place the pneumatic actuator body 110 on the base 1, ensuring that the back of the pneumatic actuator body 110 is embedded in the limiting groove at the front end of the limiting seat 6, thus stabilizing the position of the pneumatic actuator body 110. Then, place the spring and end cap 120 on top of the pneumatic actuator body 110 in sequence. Next, activate the pressing mechanism 4 to push the pressure plate 5 down, causing the T-shaped protrusion at the front end of the pressure plate 5 to overcome the spring force and press the end cap 120 onto the pneumatic actuator body 110. Then, manually or mechanically screw the screws into the screw holes 130 on the surface of the end cap 120 to achieve a tight fit between the end cap 120 and the pneumatic actuator body 110. This overcomes the problem of instability in the end cap position caused by the spring pushing upwards, which can lead to incomplete screw tightening and improve the assembly efficiency and effect between the pneumatic actuator body and the end cap.

However, the present utility model should not be limited to the content disclosed in the embodiment and the accompanying drawings. Therefore, any equivalent or modified embodiments made without departing from the spirit disclosed in the present utility model shall fall within the protection scope of the present utility model.
