Description

Technical Field

[0001] This utility model relates to the field of parts spraying technology, and in particular to an angular stroke actuator. Background Technology

[0002] An angular stroke actuator is an electric device used to control the opening and closing of valves from 0 to 90 degrees. It consists of a servo amplifier and an actuator, and now adopts an electromechanical integrated intelligent structure. It mainly operates angular stroke valves such as ball valves, butterfly valves, and plug valves. It receives 0-10mA, 4-20mA, or 1-5V standard electrical signals and converts them into angular torque to achieve automatic adjustment. The product includes two types: thrust type and torque type.

[0003] To achieve precise torque control, existing technologies typically employ specialized tools such as torque wrenches. Operators first need to use conventional tools for initial connection and positioning of components, and then switch to a torque wrench to apply and achieve the preset torque value. This process involves tool changes and multiple operations, resulting in low operational efficiency in situations requiring frequent disassembly and assembly or where space is limited.

[0004] Meanwhile, while traditional threaded or flanged connections are mature, they are time-consuming. To improve assembly efficiency, the industry has developed various quick connectors, such as bayonet or push-lock connectors. Although these quick connectors significantly shorten connection time, most designs focus only on achieving rapid physical locking and do not integrate torque application and monitoring functions. Even after using these quick connectors, if operators still need to apply specific rotational torque to the connector, they still need to use tools such as torque wrenches, failing to fundamentally integrate the operational process. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an angular stroke actuator, which aims to improve the problem that the existing connection and operation tools have limited functions and cannot achieve precise torque control while making rapid connection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An angular stroke actuator includes: a connecting shell, a fixing plate, a connecting ring; and a body, a turntable, a rotating shell, a prompt line, a pointer, a rotating rod, a torsion spring, a limit block, a compression plate, and a spring.

[0007] One end of the torsion spring is connected to the rotating rod, and the other end is connected to the rotating shell. The rotating rod passes through the interior of the rotating shell. The limiting block is radially disposed on the outer wall of the connecting ring. The fixing plate has an inlet / outlet groove for the limiting block to pass through, an annular groove communicating with the inlet / outlet groove, and a limiting groove located at the end of the annular groove.

[0008] Furthermore, the main body is fixedly connected to one end of the connecting ring, the turntable is rotatably mounted on the main body and rotates in conjunction with the rotating shell, the rotating shell, the torsion spring and the rotating rod are housed in the main body; the fixing plate is fixedly mounted inside the connecting shell, the pressing plate and the spring are mounted inside the connecting shell, and the limiting block located in the limiting groove is clamped by the elastic force of the spring.

[0009] Preferably, the indicator line is located on the main body, and the pointer is fixed to the rotating shell.

[0010] Preferably, the other end of the rotating rod is fixedly connected to the connecting ring.

[0011] Preferably, the connecting ring is also integrally provided with a connecting pipe, which is used to be sleeved on the outside of the external pipe.

[0012] Preferably, a sealing strip is provided on the inner wall of the connecting pipe.

[0013] Preferably, the end of the connecting ring is a pressing surface, which is used to abut against and press the pressing plate during insertion.

[0014] Preferably, the inlet / outlet groove is formed along the axial direction of the fixed plate, and the annular groove is formed along the circumference of the fixed plate.

[0015] Preferably, the limiting groove is a radial groove at the end of the annular groove.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting a torque indicating mechanism consisting of a turntable, a rotating shell, a torsion spring, a rotating rod, an indicator line, and a pointer, allows the torsion spring to deform when a torque is applied. The deformation is visually displayed through the relative position of the pointer and the indicator line. This solves the problem that existing manual tools cannot quantify and monitor the magnitude of the applied torque, enabling the operator to accurately control the output torque in real time, effectively avoiding equipment damage caused by excessive force, and ensuring that the connection or operation reaches the predetermined torque.

[0017] 2. This utility model solves the problems of complex structure, cumbersome operation steps and insufficient locking reliability of existing connection mechanisms by using a limiting block set on the connecting ring, which cooperates with the inlet and outlet groove, annular groove and limiting groove opened on the fixed plate, and uses a spring to push the extrusion plate to apply the final clamping force to the limiting block. The process is fast and convenient, and effectively prevents the connection from loosening under vibration conditions. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-3 The present invention provides an embodiment of an angular stroke actuator, which includes a connecting shell 8, a fixing plate 11, and a connecting ring 13. The connecting shell 8 is a hollow structure with an internal accommodating space. The fixing plate 11 is fixedly connected to the inside of the connecting shell 8, and the connecting ring 13 can be axially inserted into the accommodating space of the connecting shell 8.

[0022] The device also includes a main body 1, one end of which is fixedly connected to a connecting ring 13. A turntable 6 is rotatably connected to the main body 1. A rotating shell 2 is housed inside the main body 1. The rotating shell 2 is fixedly connected to the turntable 6 to achieve linkage rotation. A prompt line 3 is provided on the outer surface of the main body 1. A pointer 4 is fixedly connected to the rotating shell 2, and the pointer 4 points to the prompt line 3.

[0023] The rotating housing 2 contains a torsion spring 7 and a rotating rod 5. The rotating rod 5 passes through the center of the rotating housing 2 and the torsion spring 7 along its axis, and the torsion spring 7 is sleeved on the outer circumference of the rotating rod 5. One end of the torsion spring 7 is fixedly connected to the rotating rod 5, and the other end of the torsion spring 7 is fixedly connected to the rotating housing 2. The other end of the rotating rod 5 is fixedly connected to the connecting ring 13, thereby transmitting the torque applied through the turntable 6 to the connecting ring 13.

[0024] At least one limiting block 12 is integrally formed radially on the outer side wall of the connecting ring 13. The fixing plate 11 has an inlet / outlet groove 17 for the limiting block 12 to pass through axially. The fixing plate 11 also has an annular groove 16 communicating with the inlet / outlet groove 17. The annular groove 16 extends circumferentially along the fixing plate 11. At the end of the annular groove 16, a limiting groove 18 for engaging the limiting block 12 is formed. The limiting groove 18 is a radial groove.

[0025] Inside the connecting shell 8, between the fixing plate 11 and the bottom of the connecting shell 8, there is an axially sliding compression plate 10 and a spring 9. The spring 9 is a compression spring, with its two ends abutting against the compression plate 10 and the inner bottom wall of the connecting shell 8, respectively. The end of the connecting ring 13 is used to abut against and squeeze the compression plate 10 during the insertion of the connecting shell 8 to compress the spring 9.

[0026] In one specific implementation, the indicator line 3 is fixedly disposed on the outer surface of the main body 1, and the pointer 4 is fixedly connected to the outer surface of the rotating shell 2 and points to the indicator line 3. As the rotating shell 2 rotates relative to the main body 1, the relative position of the pointer 4 and the indicator line 3 changes.

[0027] The end of the rotating rod 5 away from the torsion spring 7 is fixedly connected to the connecting ring 13. This fixed connection can be welded, integrally formed, or splined to ensure torque transmission from the rotating rod 5 to the connecting ring 13.

[0028] A connecting pipe 14 is integrally formed on the connecting ring 13. The connecting pipe 14 is a hollow cylinder that extends axially from the connecting ring 13 in a direction away from the body 1. The inner diameter of the connecting pipe 14 is adapted to the outer diameter of the external pipe 15 to achieve a tight fit. To ensure the sealing of the connection, an annular groove is formed on the inner wall of the connecting pipe 14, and a sealing strip is installed in the groove.

[0029] To achieve reliable locking, the inlet / outlet groove 17 is axially formed along the fixed plate 11, while the annular groove 16 is circumferentially formed along the fixed plate 11, allowing the limiting block 12 to rotate smoothly after insertion. The limiting groove 18 is specifically a radial groove at the end of the annular groove 16. The spring 9 pushes the pressing plate 10, which in turn pushes the limiting block 12 into and locks it in the limiting groove 18, preventing the connecting ring 13 from rotating in the opposite direction.

[0030] When the angular stroke actuator of this utility model is working, the first step is to perform a connection operation. The operator tightly fits the connecting pipe 14 onto the outside of the external pipe 15, and then pushes the connecting ring 13 into the inside of the connecting shell 8. During the pushing process, the limiting block 12 on the connecting ring 13 aligns with and passes through the inlet and outlet groove 17 opened on the fixing plate 11. At the same time, the end of the connecting ring 13 abuts against and pushes the compression plate 10, so that the spring 9 is compressed and stores elastic energy.

[0031] After the limiting block 12 has completely passed through the inlet / outlet groove 17, the operator rotates the main body 1 at the top of the device. At this time, the connecting ring 13 rotates accordingly, causing the limiting block 12 to slide along the annular groove 16 on the fixed plate 11. When the limiting block 12 rotates to the limiting groove 18 at the end of the annular groove 16, the compressed spring 9 releases its elastic force. This elastic force acts on the connecting ring 13 through the pressing plate 10, pushing the limiting block 12 in and firmly locking it in the limiting groove 18, thereby completing a quick and reliable locking connection.

[0032] When applying torque, the operator rotates the top turntable 6, which drives the rotating shell 2 to rotate synchronously. Since the rotating rod 5 is fixedly connected to the external pipe 15 through the connecting ring 13, its rotation will be resisted by the external load. This resistance causes the torsion spring 7, which is connected to the rotating rod 5 at one end and the rotating shell 2 at the other end, to undergo torsional deformation. The degree of torsional deformation is proportional to the magnitude of the applied torque. Since the rotating shell 2 rotates relative to the body 1 fixed to the connecting ring 13, the pointer 4 fixed on the rotating shell 2 will shift relative to the indicator line 3 engraved on the body 1. By observing the relative position of the pointer 4 and the indicator line 3, the operator can intuitively judge the magnitude of the applied torque and achieve precise torque control.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
