Description

Technical Field

[0001] This utility model relates to the field of pneumatic actuator technology, and in particular to a pneumatic actuator with auxiliary positioning. Background Technology

[0002] Pneumatic actuators are devices that use compressed air as a power source to drive mechanical devices and are widely used in automated control systems. Their basic working principle is that the pressure of the air causes the piston or diaphragm inside the actuator to move, thereby achieving actions such as pushing a robotic arm or opening and closing a valve. The advantages of pneumatic actuators are their simple structure, fast response, stable operation, and ability to be used in hazardous environments because air as a power source is relatively safe. Common pneumatic actuators include cylinders and pneumatic valve actuators. Pneumatic actuators are widely used in industries such as manufacturing, chemical engineering, and logistics, and are particularly suitable for applications requiring frequent start-stop operations and rapid response.

[0003] Currently, existing pneumatic actuators typically employ simple drive structures. While they can perform basic drive tasks, they still have limitations in terms of precise control, stability, and adaptability to complex working conditions. Especially in applications requiring high-precision positioning and long-term stable operation, existing pneumatic actuators, lacking effective positioning and guidance mechanisms, are prone to unstable connections between the actuator output and the equipment, thereby affecting system reliability and operating efficiency. Furthermore, the extension and retraction movements of existing pneumatic actuators are often affected by the external environment, leading to imbalances and unstable movements in the equipment.

[0004] Therefore, there is an urgent need for a new type of pneumatic actuator that can achieve precise telescopic control through an auxiliary positioning device and improve the stability and reliability of equipment installation to meet the application requirements under high precision and high load conditions. Based on this, we propose a pneumatic actuator with auxiliary positioning. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a pneumatic actuator with auxiliary positioning, which can solve the problems of existing pneumatic actuators in terms of precise control, stability, adaptability to complex working conditions, high-precision positioning, and imbalance of telescopic adjustment.

[0007] To solve the above-mentioned technical problems, this utility model provides a pneumatic actuator with auxiliary positioning, which adopts the following technical solution: it includes a positioning base, a positioning transmission assembly is sleeved on the outside of the positioning base, a fixed base plate is installed on the top of the positioning base, and an actuator body is provided on the top of the fixed base plate;

[0008] The positioning transmission assembly includes a first guide cover, a second guide cover connected to one side of the first guide cover, and two sets of guide grooves are provided on the inner sides of both the first guide cover and the second guide cover.

[0009] Optionally, a through groove is provided in the middle of the positioning base, two sets of guide plates are connected to the two sides of the positioning base respectively, and fixing holes are provided at the four corners of the positioning base and the fixing base plate respectively.

[0010] Optionally, the guide plate and the guide groove are matched, and the guide plate and the guide groove are in a sliding fit.

[0011] Optionally, a fixing plate is installed on the top of the actuator body and the outer side of the first guide cover and the second guide cover, respectively, and a drive shaft is connected to the output end of the actuator body.

[0012] Optionally, multiple sets of splicing inserts are connected to one side edge of the first guide cover, and multiple sets of splicing slots are opened on one side edge of the second guide cover. The splicing slots are matched with the structure of the splicing inserts, and the splicing slots and splicing inserts are engaged by a snap-fit.

[0013] Optionally, the bottom center of the first guide cover and the second guide cover are connected to a transmission seat, the transmission seat and the through groove are in sliding fit, and a shaft hole is opened between the two sets of transmission seats, the shaft hole and the transmission shaft are fixedly connected.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. This solution uses a positioning transmission assembly fitted outside the positioning base. This positioning transmission assembly mainly consists of a first guide cover and a second guide cover, which are connected to each other via a splicing plate and a splicing slot. The structural design of the splicing plate and the splicing slot with a snap-fit ​​fit ensures that the two can be stably limited and connected, so that the first guide cover and the second guide cover can be firmly connected together. Through the structural design of the sliding fit between the guide plate and the guide groove, the spliced ​​first guide cover and the second guide cover can also be fitted outside the positioning base. At the same time, the spliced ​​first guide cover and the second guide cover can also be limited and slid on the outside of the positioning base according to the usage, so that the spliced ​​guide cover can be slidably limited on the outside of the positioning base.

[0016] 2. This solution uses a fixed connection design between the drive shaft and the shaft hole, allowing the output end of the actuator body to be firmly connected to the positioning transmission component. When the actuator body drives the drive shaft connected to the output end to extend or retract, the positioning transmission component can slide on the outside of the positioning base, thereby fixing the equipment to be transmitted at one end of the positioning base. As can be seen from the above, the pneumatic actuator designed in this solution not only ensures the stable installation of the equipment but also provides positioning and guiding functions on both sides, avoiding the unstable installation and unbalanced extension / retraction adjustment problems that may occur when the output end of the traditional actuator body is directly connected to the equipment.

[0025] 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.

[0026] Example: Refer to Figures 1 to 6 This utility model provides an embodiment of a pneumatic actuator with auxiliary positioning, including a positioning base 1, a positioning transmission assembly 2 sleeved on the outside of the positioning base 1, a fixed base plate 3 mounted on the top of the positioning base 1, and an actuator body 4 disposed on the top of the fixed base plate 3. The positioning transmission assembly 2 includes a first guide cover 5, a second guide cover 6 connected to one side of the first guide cover 5, and two sets of guide grooves 7 opened on the inner sides of both the first guide cover 5 and the second guide cover 6. The pneumatic actuator, through the structural design of the fixed connection between the shaft hole 16 and the transmission shaft 12, can fix the output end of the actuator body 4 and the positioning transmission assembly 2 together. When the actuator body 4 drives the transmission shaft 12 connected to the output end to perform telescopic movement, the positioning transmission assembly 2 slidably sleeved on the outside of the positioning base 1 can install and fix the equipment to be transmitted at one end of the positioning base 1, and at the same time, it can also play a positioning and guiding role on both sides of the equipment that is telescopically driven at one end of the positioning base 1. This solves the problem of unstable installation and unbalanced telescopic adjustment caused by the direct connection between the output end of the existing actuator body 4 and the equipment.

[0027] A through groove 8 is provided in the middle of the positioning base 1. Two sets of guide plates 9 are connected to both sides of the positioning base 1. Fixing holes 8 are also provided at the four corners of the positioning base 1 and the fixed base plate 3. The fixed base plate 3, with the actuator body 4 mounted on top, can be connected and fixed to the top of the positioning base 1 through the fixing holes 8 at the four corners of the positioning base 1 and the fixed base plate 3. The guide plates 9 and guide grooves 7 are structurally matched and have a sliding fit. Through the sliding fit structure between the guide plates 9 and guide grooves 7, the first guide cover 5 and the second guide cover 6 spliced ​​together can be connected. While being fitted onto the outside of the positioning base 1, the first guide cover 5 and the second guide cover 6, which are spliced ​​together, can also slide and limit their movement on the outside of the positioning base 1 according to the usage. Fixing plates 11 are respectively installed on the top of the actuator body 4 and the outside of the first guide cover 5 and the second guide cover 6. The output end of the actuator body 4 is connected to a drive shaft 12. By adding fixing plates 11 to the top of the actuator body 4 and the outside of the first guide cover 5 and the second guide cover 6, it is convenient to connect and fix the actuator body 4 to the support frame. The equipment to be driven is also connected and fixed to the output end of the actuator body 4.

[0028] Multiple sets of splicing inserts 13 are connected to one side edge of the first guide cover 5, and multiple sets of splicing slots 14 are opened on one side edge of the second guide cover 6. The splicing slots 14 and splicing inserts 13 are structurally matched and are snap-fitted together. Through the snap-fit ​​structure between the splicing slots 14 and splicing inserts 13, the first guide cover 5 and the second guide cover 6 can be spliced ​​and fixed together. A transmission seat 15 is connected to the bottom center of the first guide cover 5 and the second guide cover 6. The transmission seat 15 is slidably fitted with the through groove 8. A shaft hole 16 is opened between the two sets of transmission seats 15. The shaft hole 16 is fixedly connected to the transmission shaft 12. Through the sliding fit structure between the transmission seat 15 and the through groove 8, the sliding between the positioning transmission component 2 and the inside of the positioning base 1 can prevent the positioning transmission component 2 from getting stuck when sliding and adjusting outside the positioning base 1.

[0029] Working principle: This solution uses a positioning transmission assembly 2 fitted outside the positioning base 1. The positioning transmission assembly 2 mainly consists of a first guide cover 5 and a second guide cover 6. The positioning transmission assembly 2 uses a splicing insert plate 13 connected to one side edge of the first guide cover 5 and a splicing slot 14 opened on one side edge of the second guide cover 6. Because the splicing slot 14 and the splicing insert plate 13 are structurally matched and have a snap-fit ​​fit, the first guide cover 5 and the second guide cover 6 can be limited and connected together. Through the guide groove 7 opened inside the first guide cover 5 and the second guide cover 6, and the guide plates 9 installed on both sides of the positioning base 1, because the guide plates 9 and the guide groove 7 are structurally matched and have a sliding fit, the first guide cover 5 and the second guide cover 6 can be fitted outside the positioning base 1 while being limited and slidable on the outside of the positioning base 1 according to the usage.

[0030] The pneumatic actuator designed in this scheme, through the structural design of the fixed connection between the shaft hole 16 and the transmission shaft 12, can fix the output end of the actuator body 4 and the positioning transmission component 2 together. When the actuator body 4 drives the transmission shaft 12 connected to the output end to perform telescopic movement, the positioning transmission component 2, which is slidably sleeved on the outside of the positioning base 1, can install and fix the equipment to be transmitted at one end of the positioning base 1, and at the same time, it can also play a positioning and guiding role on both sides of the equipment that is telescopically driven at one end of the positioning base 1. This solves the problem of unstable installation and unbalanced telescopic adjustment caused by the direct connection between the output end of the existing actuator body 4 and the equipment.

[0031] 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.
