Description

Technical Field

[0001] This utility model relates to the technical field of ball valve assembly devices, and in particular to an automated ball valve assembly device. Background Technology

[0002] Ball valves are a common type of fluid control valve. Due to their simple structure and low fluid resistance, they are widely used in various pipeline systems to regulate, open, or close the flow of fluids. Ball valve assembly equipment is a type of mechanical equipment specifically designed for assembling ball valves during ball valve production. Working in conjunction with workers, it can improve the production efficiency of ball valves.

[0003] However, before workers can tighten the bolts onto the ball valve, a ball valve assembly device is needed to clamp and stabilize the two valve body parts of the ball valve so that workers can connect the two valve bodies together using bolts. Currently, most ball valve assembly devices on the market are not convenient for clamping ball valves with different valve pipe diameters on the valve body, which reduces the applicability of the assembly device and results in poor compatibility with different product lines.

[0004] Therefore, those skilled in the art have provided an automated ball valve assembly device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automated ball valve assembly device. The device uses a second servo motor in the clamping mechanism to drive the clamping bidirectional threaded rod to rotate, which in turn causes the slider to move the clamping plate. In conjunction with the first servo motor in the adjusting mechanism, the adjusting bidirectional threaded rod is driven to rotate, which in turn causes the moving block to move the connecting block. This facilitates the clamping of the ball valve body and also makes it easier for workers to tighten bolts and assemble the valve body.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automated ball valve assembly device includes a working platform, an adjusting mechanism, and a clamping mechanism. The adjusting mechanism is located at the upper end of the working platform and includes a support plate. A clamping mechanism is located at the front end of the support plate and includes two clamping seats. Each clamping seat has a sliding groove on its side near the center of the working platform. A second protective box is fixedly connected to the middle of the upper end of each clamping seat. A second servo motor is located on the bottom surface inside each second protective box. The output shaft of each second servo motor passes through the second protective box and is fixedly connected to a clamping bidirectional threaded rod. A slider is threadedly connected to the upper and lower ends of the outer wall of the clamping bidirectional threaded rod. A clamping plate is fixedly connected to the side of each slider near the center of the working platform, and a friction pad is fixedly connected to the side of each clamping plate near the center of the clamping seat.

[0008] Through the above technical solution, the two second servo motors inside the two second protective boxes in the clamping mechanism drive the clamping bidirectional threaded rod inside the slide to rotate, allowing the slider threaded to the clamping bidirectional threaded rod to slide inside the slide, thereby changing the distance between the clamping plates on both sides of the same group, and stably clamping the ball valve body of different sizes. The four friction pads fixedly connected to the four clamping plates can increase the friction between the clamping plates and the valve body, improve the stability of clamping, and make the valve body less likely to detach.

[0009] Furthermore, the lower end of the support plate is fixedly connected to the working platform, a moving groove is provided in the middle of the outer wall of the front end of the support plate, a first protective box is fixedly connected to the outer wall of one side of the support plate, a first servo motor is provided on the bottom surface inside the first protective box, the output shaft of the first servo motor passes through the first protective box and is fixedly connected to an adjusting bidirectional threaded rod, and moving blocks are threadedly connected to both sides of the outer wall of the adjusting bidirectional threaded rod.

[0010] Through the above technical solution, the first servo motor inside the first protection box of the adjustment mechanism drives the adjusting bidirectional threaded rod to rotate inside the moving groove, which in turn drives the two moving blocks that are threadedly connected to the adjusting bidirectional threaded rod to slide inside the moving groove, thereby changing the distance between the two valve bodies to adapt to the length of the ball valve and providing support for the valve bodies, making it easier for subsequent workers to tighten bolts to fix the two valve bodies together.

[0011] Furthermore, support legs are fixedly connected to the four corners of the lower end of the work platform, and a PLC control panel is fixedly connected to the front end of the other side of the upper end of the work platform.

[0012] The above technical solution allows the work platform to be stably placed in the work area by the four support legs fixedly connected to the lower end of the work platform, and also raises the work platform above the ground to a height that is more comfortable for the operator to operate. The PLC control panel fixedly connected to the work platform makes it easy for the operator to control the operation of the device.

[0013] Furthermore, a fixed frame is fixedly connected to the middle of the lower end of the work platform, and drawers are slidably connected to the inner walls on both sides of the fixed frame;

[0014] The above technical solution involves setting a drawer inside the fixed frame that is fixedly connected to the lower end of the work platform, which facilitates the storage of tools needed during operation by the staff.

[0015] Furthermore, the lower ends of the clamping bidirectional threaded rods all penetrate through the clamping seat and are rotatably connected to the bottom surface inside the slide groove, and the sliders all slide inside the slide groove;

[0016] Through the above technical solution, by rotatably connecting the lower end of the clamping bidirectional threaded rod to the bottom surface inside the slide groove, the clamping bidirectional threaded rod can be stably rotated inside the slide groove under the drive of the second servo motor, thereby stably driving the slider to move inside the slide groove and changing the distance between the clamping plates fixedly connected to the slider.

[0017] Furthermore, a laser emitter is fixedly connected to the upper end of the clamping plate on the other side, and a reflector is fixedly connected to the upper end of the clamping plate on the other side.

[0018] By using the above technical solution, a laser emitter is fixed to the upper end of one clamping plate on the other side, and a reflector is fixed to the upper end of one clamping plate on one side. This allows the operator to use the PLC control panel to control two second servo motors to drive two clamping bidirectional threaded rods to rotate and change the distance between the clamping plates on both sides. At this time, the operator can observe whether the laser emitted by the laser emitter can illuminate the reflector to determine whether there is a large offset between the two valve bodies.

[0019] Furthermore, the other side of the adjusting bidirectional threaded rod passes through the support plate and is rotatably connected to the inner wall of the other side of the moving groove, and the moving blocks slide inside the moving groove;

[0020] Through the above technical solution, by rotating the other side of the adjusting bidirectional threaded rod to the inner wall of the other side of the moving groove, the adjusting bidirectional threaded rod can be stably rotated inside the moving groove under the drive of the first servo motor, thereby stably driving the moving block to move inside the moving groove, changing the distance between the connecting blocks fixedly connected to the moving block, and thus changing the distance between the two clamping seats.

[0021] Furthermore, each of the outer walls at the front end of the movable block is fixedly connected to a connecting block, and the side of the clamping seat away from the center of the working platform is fixedly connected to the connecting block.

[0022] Through the above technical solution, by fixing the clamping seat and the connecting block together, the rotating adjusting bidirectional threaded rod, driven by the first servo motor, drives the moving block that is threadedly connected to it to move inside the moving groove. The moving block is fixedly connected to the connecting block, and thus, driven by the movement of the connecting block, the clamping seat can move along the moving groove, changing the distance between the two clamping seats.

[0023] This utility model has the following beneficial effects:

[0024] 1. The ball valve automated assembly device proposed in this utility model uses two second servo motors inside two second protective boxes in the clamping mechanism to drive the clamping bidirectional threaded rod inside the slide groove to rotate, so that the slider threaded to the clamping bidirectional threaded rod slides inside the slide groove, thereby changing the distance between the clamping plates on both sides of the same group, and stably clamping the ball valve body of different sizes, improving the applicability of the assembly device and enhancing the compatibility with different product lines.

[0025] 2. The ball valve automated assembly device proposed in this utility model uses a first servo motor inside the first protective box of the adjustment mechanism to drive the adjusting bidirectional threaded rod to rotate inside the moving groove, thereby driving two moving blocks threaded to the adjusting bidirectional threaded rod to slide inside the moving groove, thereby changing the distance between the two valve bodies to adapt to the length of the ball valve and providing support for the valve bodies, making it easy for workers to tighten bolts to connect and fix the two valve bodies.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 One specific embodiment provided by this utility model:

[0035] An automated ball valve assembly device includes a working platform 1, an adjusting mechanism 4, and a clamping mechanism 6. The adjusting mechanism 4 is provided at the upper end of the working platform 1. The adjusting mechanism 4 includes a support plate 401. The clamping mechanism 6 is provided at the front end of the support plate 401. The clamping mechanism 6 includes two clamping seats 601. Each clamping seat 601 has a sliding groove 602 on one side near the center of the working platform 1. A second protective box 603 is fixedly connected to the middle of the upper end of each clamping seat 601. A second servo motor 604 is provided on the bottom surface inside the second protective box 603. The output shaft of the second servo motor 604 passes through the second protective box 603 and is fixedly connected to a clamping bidirectional threaded rod 605. The upper and lower ends of the outer wall of the clamping bidirectional threaded rod 605 are threadedly connected to sliders 606. A clamping plate 607 is fixedly connected to one side of the slider 606 near the center of the working platform 1. A friction pad 608 is fixedly connected to one side of the clamping plate 607 near the center of the clamping seat 601.

[0036] Support legs 2 are fixedly connected to the four corners of the lower end of the work platform 1. A PLC control panel 3 is fixedly connected to the front end of the other side of the upper end of the work platform 1. The four support legs 2 fixedly connected to the lower end of the work platform 1 allow the work platform 1 to be stably placed in the work area, and also raise the work platform 1 above the ground to a height that is more comfortable for the operator to operate. The PLC control panel 3 fixedly connected to the work platform 1 allows the operator to control the operation of the device. A fixed frame 7 is fixedly connected to the middle of the lower end of the work platform 1. Drawers 8 are slidably connected to the inner walls on both sides of the fixed frame 7. The drawers 8 inside the fixed frame 7 fixedly connected to the lower end of the work platform 1 are convenient for the operator to store the tools needed during operation. The lower ends of the clamping bidirectional threaded rods 605 all pass through the clamping seat 601 and are rotatably connected to the bottom surface inside the slide groove 602. The sliders 606 all slide inside the slide groove 602. By allowing the lower ends of the clamping bidirectional threaded rods 605 to slide in the slide groove 602, the operation is completed. The rotating connection of the bottom surface inside 02 allows the clamping bidirectional threaded rod 605 to rotate stably inside the slide groove 602 under the drive of the second servo motor 604, thereby stably driving the slider 606 to move within the slide groove 602, changing the distance between the clamping plates 607 fixedly connected to the slider 606. A laser emitter 609 is fixedly connected to the upper end of the clamping plate 607 on the other side, and a reflector 610 is fixedly connected to the upper end of the clamping plate 607 on one side. By fixing a laser emitter 609 to the upper end of one clamping plate 607 on the other side, and a reflector 610 to the upper end of one clamping plate 607 on one side, the operator can use the PLC control panel 3 to control the two second servo motors 604 to drive the two clamping bidirectional threaded rods 605 to rotate, changing the distance between the clamping plates 607 on both sides, and can judge whether there is a large offset between the two valve bodies by observing whether the laser emitted by the laser emitter 609 can illuminate the reflector 610.

[0037] Reference Figure 1 , Figure 2 and Figure 4 The lower end of the support plate 401 is fixedly connected to the working platform 1. A moving groove 402 is provided in the middle of the outer wall of the front end of the support plate 401. A first protective box 403 is fixedly connected to the outer wall of one side of the support plate 401. A first servo motor 404 is provided on the bottom surface inside the first protective box 403. The output shaft of the first servo motor 404 passes through the first protective box 403 and is fixedly connected to an adjusting bidirectional threaded rod 405. Moving blocks 406 are threadedly connected to both sides of the outer wall of the adjusting bidirectional threaded rod 405.

[0038] The other side of the adjusting bidirectional threaded rod 405 passes through the support plate 401 and is rotatably connected to the inner wall of the other side of the moving groove 402. The moving blocks 406 slide inside the moving groove 402. By rotatably connecting the other side of the adjusting bidirectional threaded rod 405 to the inner wall of the other side of the moving groove 402, the adjusting bidirectional threaded rod 405 can stably rotate inside the moving groove 402 under the drive of the first servo motor 404. This stably drives the moving blocks 406 to move within the moving groove 402, changing the distance between the connecting blocks 5 fixedly connected to the moving blocks 406, thereby changing the distance between the two clamping seats 60. Between the two work platforms 1, the outer wall of the front end of the movable block 406 is fixedly connected to the connecting block 5. The side of the clamping seat 601 away from the center of the work platform 1 is fixedly connected to the connecting block 5. By fixing the clamping seat 601 to the connecting block 5, the rotating adjusting bidirectional threaded rod 405, driven by the first servo motor 404, drives the movable block 406, which is threadedly connected to it, to move inside the movable groove 402. The movable block 406 is fixedly connected to the connecting block 5. Thus, driven by the movement of the connecting block 5, the clamping seat 601 can move along the movable groove 402, changing the distance between the two clamping seats 601.

[0039] Working Principle: When using this automated ball valve assembly device, the operator first powers the device with an external power supply. Then, the first valve body is placed between the two clamping plates 607 on one side. The PLC control panel 3 activates the second servo motor 604 on one side, which rotates the clamping bidirectional threaded rod 605 on the other side. This causes the two sliders 606 on one side to move the two clamping plates 607, clamping the first valve body. Next, the operator places the second valve body between the two clamping plates 607 on the other side. The PLC control panel 3 activates the second servo motor 604 on the other side, which rotates the clamping bidirectional threaded rod 605 on the other side. This causes the two sliders 606 on the other side to move the two clamping plates on the other side. Movement 607 clamps the second valve body. After clamping the two valve bodies, the operator observes whether the light emitted by the laser emitter 609 shines on the reflector 610. If not, the clamping needs to be readjusted. Finally, the operator starts the first servo motor 404 through the PLC control panel 3 to drive the adjusting bidirectional threaded rod 405 to rotate, which drives the two moving blocks 406 to move in the moving groove 402. After the two clamped valve bodies are brought close to each other, the operator pulls out the drawer 8 to take out the tools and bolts stored inside to connect and fix the valve bodies. After the bolts are tightened, the operator uses the PLC control panel 3 to start the two second servo motors 604 to release the clamp 607 from the valve bodies. The operator then takes out the assembled ball valve.

Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific 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.
