Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic actuator assembly, in particular to a tool used for assembling a single-acting pneumatic actuator spring. Background Art

[0002] Single-acting pneumatic actuator is a common pneumatic actuator used to control the opening and closing of valves, valve balls or other mechanical devices.

[0003] The existing one, such as China Patent No.: CN219925153U, is a tool for assembling the spring of a single-acting pneumatic actuator, which consists of a pneumatic actuator cylinder clamp and a translation mechanism. The horizontal push cylinders on the two groups of pneumatic clamping assemblies on the pneumatic actuator cylinder clamp push the clamping blocks to move relatively close to each other, and the cylinder clamp is fixed between the two groups of clamping blocks through two groups of contoured clamping grooves and rubber pads, and the cylinder is clamped and fixed. The positioning end of the cylinder is inserted into the limit ring, and the cylinder will not fall off relative to the two groups of pneumatic clamping assemblies. The positioning effect of the cylinder is good and the clamping is stable; the servo motor on the translation mechanism drives the screw rod to rotate, driving the moving seat and the support to move back and forth, which can realize the transfer of the pneumatic actuator cylinder clamp station, so that the pneumatic actuator cylinder clamp together with the cylinder can be transferred from the spring pressing station to the end cover pressing station, which can effectively improve the assembly efficiency of the pneumatic actuator. Although this patent can achieve the assembly of the pneumatic actuator spring.

[0004] However, since springs need to be installed at both ends of the pneumatic actuator, when installing the spring at the other end of the actuator, the prior art requires removing the actuator from the clamp and then clamping the other end of the actuator upward. The operation is very cumbersome and the assembly efficiency needs to be further improved. Therefore, it is necessary to propose a new type of tooling for assembling the spring of a single-acting pneumatic actuator. Utility Model Content

[0005] The utility model mainly provides a pneumatic actuator spring assembly tool which is convenient for installing springs at two ends of the pneumatic actuator.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a tooling for assembling a single-acting pneumatic actuator spring, comprising a base, side plates are symmetrically fixedly installed on the top of the base, second transmission wheels are arranged on the outer surfaces of the opposite sides of the two side plates near the top, a connecting shaft is fixedly installed on one end of the second transmission wheel, the outer surfaces of the two connecting shafts slide through the outer surfaces of the side plates and extend to the other side, a motor is fixedly installed on the top of the base near the left side, a rotating shaft is fixedly installed on the output end of the motor, the outer surface of the rotating shaft slides through the outer surfaces of the two side plates and extends to the other side, a first transmission wheel is fixedly installed on the outer surface of the rotating shaft near both ends, and a transmission belt is arranged between the outer surfaces of the first transmission wheel and the second transmission wheel.

The pneumatic telescopic rod is provided to facilitate pushing the support plate to move upward or downward.

[0009] Preferably, the telescopic end of the pneumatic telescopic rod is fixedly installed with a support plate, and a limit ring is fixedly installed on the top of the support plate. The provision of the support plate facilitates the installation of the limit ring, and the shape of the limit ring corresponds to the shape of the end of the pneumatic actuator, thereby positioning the pneumatic actuator.

[0010] Preferably, the outer surfaces of the two connecting shafts are fixedly installed with rotating blocks, and a limit groove is provided through the outer surface of the rotating block. The limit groove cooperates with the limit pin, and the limit groove is provided in a 180-degree arc. After cooperating with the limit pin, the rotating block can only rotate within the specified travel range, thereby preventing the rotating block from flipping over the travel range.

[0011] Preferably, connecting rods are fixedly installed on the outer surface of one side of the rotating block near the four corners, a connecting plate is fixedly installed between the ends of the plurality of connecting rods, a push cylinder is fixedly installed on the outer surface of one side of the connecting plate, the telescopic end of the push cylinder slides through the outer surface of the connecting plate and extends to the other side, and a clamping block is fixedly installed on the telescopic end of the push cylinder, and by starting the two push cylinders and cooperating with the clamping block, the cylinder body can be clamped, thereby fixing the cylinder body, which is convenient for assembling the spring of the actuator.

When the clamping block moves, the limit rods penetrate the connecting plate and slide against each other, thereby guiding the clamping block and improving the stability of the clamping block.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, the rotating shaft is driven to rotate by starting the motor, and the rotating block is rotated by the cooperation of the first transmission wheel, the transmission belt, the second transmission wheel and the connecting shaft.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] See also Figure 1-5 The utility model provides a technical solution: a tooling for assembling a spring of a single-acting pneumatic actuator, comprising a base 1, a side plate 2 is symmetrically fixedly installed on the top of the base 1, a second transmission wheel 44 is arranged near the top of the outer surface of the opposite sides of the two side plates 2, a connecting shaft 45 is fixedly installed at one end of the second transmission wheel 44, the outer surfaces of the two connecting shafts 45 slide through the outer surface of the side plate 2 and extend to the other side, a motor 4 is fixedly installed at the top of the base 1 near the left side, a rotating shaft 41 is fixedly installed at the output end of the motor 4, the outer surface of the rotating shaft 41 slides through the outer surfaces of the two side plates 2 and extends to the other side, a first transmission wheel 42 is fixedly installed on the outer surface of the rotating shaft 41 near both ends, and a transmission belt 43 is arranged between the outer surfaces of the first transmission wheel 42 and the second transmission wheel 44.

[0025] like Figure 2 As shown, a fixing plate 21 is fixedly connected near the middle between the outer surfaces of the opposite sides of the two side panels 2, and a limiting pin 22 is fixedly connected near the top of the outer surfaces of the opposite sides of the two side panels 2. The fixing plate 21 is provided to install the pneumatic telescopic rod 3 and connect the two side panels 2 at the same time. The limiting pin 22 is provided to guide and limit the limiting groove 51.

[0026] like Figure 3 As shown, the pneumatic telescopic rod 3 is fixedly installed at the bottom of the fixed plate 21, and the telescopic end of the pneumatic telescopic rod 3 slides through the bottom of the fixed plate 21 and extends upward. The pneumatic telescopic rod 3 is arranged to facilitate pushing the support plate 31 to move upward or downward.

[0027] like Figure 3 As shown, the telescopic end of the pneumatic telescopic rod 3 is fixedly installed with a support plate 31, and the top of the support plate 31 is fixedly installed with a limit ring 32. The support plate 31 is provided to facilitate the installation of the limit ring 32. The shape of the limit ring 32 corresponds to the shape of the end of the pneumatic actuator, thereby positioning the pneumatic actuator.

[0028] like Figure 5As shown, the outer surfaces of the two connecting shafts 45 are fixedly installed with the rotating block 5, and the outer surface of the rotating block 5 is penetrated by a limit groove 51, which cooperates with the limit pin 22. The limit groove 51 is opened in a 180-degree arc. After cooperating with the limit pin 22, the rotating block 5 can only rotate within the specified travel range, thereby preventing the rotating block 5 from flipping over the travel.

[0029] like Figure 5 As shown, connecting rods 52 are fixedly installed on the outer surface of one side of the rotating block 5 near the four corners, and a connecting plate 53 is fixedly installed between the ends of the multiple connecting rods 52. A push cylinder 54 is fixedly installed on the outer surface of one side of the connecting plate 53. The telescopic end of the push cylinder 54 slides through the outer surface of the connecting plate 53 and extends to the other side. A clamping block 55 is fixedly installed on the telescopic end of the push cylinder 54. By starting two push cylinders 54 and cooperating with the clamping block 55, the cylinder body can be clamped, and then the cylinder body is fixed, which is convenient for assembling the spring of the actuator.

[0030] like Figure 5 As shown, limit rods 56 are fixedly installed on the outer surface of one side of the clamp block 55 near the four corners, and the outer surfaces of multiple limit rods 56 interactively penetrate the outer surface of the connecting plate 53 and extend to the other side. When the clamp block 55 moves, the limit rods 56 penetrate the connecting plate 53 and slide against each other, which guides the clamp block 55 and improves the stability of the clamp block 55.

[0031] The method of use and working principle of this device: When in use, insert the cylinder of the pneumatic actuator into the limit ring 32, and push the cylinder upward to the clamping range of the clamp block 55 by starting the pneumatic telescopic rod 3, and then start the two horizontal push cylinders 54 at the same time, and cooperate with the clamp block 55 to clamp the cylinder, so that the cylinder is fixed, which is convenient for assembling the spring of the actuator. When it is necessary to assemble the spring at the other end of the actuator, the limit ring 32 is moved downward by the pneumatic telescopic rod 3. Since the cylinder is still clamped, the cylinder will not move downward with the limit ring 32 , so that the cylinder is suspended in the air. After the cylinder is suspended in the air, the rotating shaft 41 is driven to rotate by starting the motor 4, and the rotating block 5 is rotated by the cooperation of the first transmission wheel 42, the transmission belt 43, the second transmission wheel 44 and the connecting shaft 45. When the rotating block 5 rotates 180 degrees, the cylinder can be flipped, which is convenient for assembling the spring at the other end. When the rotating block 5 is rotating, the limiting groove 51 on the rotating block 5 and the limiting pin 22 on the side plate 2 slide with each other, which plays a role in limiting the rotating block 5, ensuring the accuracy of the flipping angle of the rotating block 5 and avoiding flipping overtravel.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
