Description

Technical Field

[0001] The utility model relates to a plugging device for supporting a round pipe. Background Art

[0002] Automated production is the production carried out by using automation technology. It has brought profound impacts to human society, the most important of which is that it has greatly improved social labor productivity and enhanced human's ability to transform nature. According to the degree of automation, it can be divided into semi-automated production and fully automated production. The former is that part of the production process uses automation technology and part is operated manually; the latter is that all processes of the whole production process, including loading, unloading, packaging, transportation, etc., do not require direct human participation in the operation, but only indirectly supervise the work of the machine.

[0003] However, there are certain difficulties in applying automation technology to the plugging of round tubes, because two objects are needed to complete this action - the plug and the round tube. Therefore, the round tube and the plug need to be loaded separately, and the plug must be aligned with the mouth of the round tube. Then the plug is pressed into the mouth of the tube through a pressure device. The difficulty lies in how to align the plug with the mouth of the tube and ensure accuracy. Therefore, a mechanism is needed to realize the automatic loading of the plug and ensure that the plug is aligned with the mouth of the tube. Utility Model Content

[0004] The purpose of the utility model is to solve the above deficiencies in the prior art and to provide a plugging device for supporting a round tube.

[0005] A plugging device for supporting a round tube comprises a frame, an upper end surface of the frame is provided with a frame bottom plate, a plugging mechanism is provided on the frame bottom plate, a plugging station is provided on the frame bottom plate, a fixed bracket is provided on the plugging station, and the fixed bracket is used to place a workpiece to be processed, wherein the workpiece to be processed is a round tube;

[0006] The plugging mechanism includes a feeding mechanism, a discharging mechanism, and a rotating operating mechanism. The feeding mechanism, the discharging mechanism, and the rotating operating mechanism are located on one side of the plugging station. A support plate is provided on the other side of the plugging station. The discharging mechanism is used to place the plug sent by the feeding mechanism into the rotating operating mechanism. The rotating operating mechanism is used to change the position of the plug so that the plug is aligned with the pipe mouth of the round tube.

[0007] Working principle: The feeding work is completed through the feeding mechanism, and then the plug is placed in the rotary operating mechanism through the discharging mechanism. The rotary operating mechanism is rotated to a suitable position to align the plug with the pipe mouth, and then the plug is pressed into the pipe mouth, thereby realizing the function of automatic plugging.

[0008] In order to realize automatic feeding, the feeding mechanism includes a vibration plate and a direct vibration feeding device. The vibration plate arranges a plurality of plugs, and then the direct vibration feeding device successively delivers the plugs to the feeding port.

[0009] In order to realize automatic unloading, the unloading mechanism includes a suction cup, a lifting cylinder, and a horizontal cylinder. The floating joint of the horizontal cylinder is connected to the lifting cylinder through a first connecting plate, and the floating joint of the second cylinder is connected to the suction cup through a second connecting plate. The stopper is sucked by the suction cup, and then the suction cup is moved to the position of the rotating operating mechanism through the lifting cylinder and the water bottle cylinder.

[0010] The rotary operating mechanism includes a rotary cylinder, a propulsion cylinder, a guide mechanism, and a reset mechanism. The rotary structure of the rotary cylinder is connected to a rotary connecting block. One end face of the rotary connecting block is fixedly connected to a linear bearing. The linear bearing is movably connected to a plugging movable rod.

[0011] The plugging movable rod is fixedly connected to the second connecting block, and the second connecting block is connected to the floating joint of the propulsion cylinder through a connecting structure. The movement trajectory of the floating joint of the propulsion cylinder is parallel to the bottom plate of the frame. The reset mechanism is used to reset the plugging movable rod, and the plug is pressed into the pipe mouth through rotation and translation. The cylinder is rotated to align the plug with the pipe mouth, and the propulsion cylinder pushes the connecting structure to drive the plugging movable rod.

[0012] In order to prevent the connection structure from being offset when pushed by the propulsion cylinder, the connection structure includes a second guide column, which is fixedly connected to the second connection block. The second guide column is movably arranged in the first connection block, and the first connection block is fixed on the adjacent side end face of the end face of the second connection block on the rotating connection block.

[0013] In order to ensure that after completing a plugging work, the plugging movable rod can be reset to wait for the next plugging work, the reset mechanism includes a first connecting bolt and a second connecting bolt. The first connecting bolt is connected to the first connecting block, and the second connecting bolt is connected to the second connecting block. The two sides of the tension spring are respectively connected to the first connecting bolt and the second connecting bolt. Since the first connecting block is fixed, when the thrust cylinder does not apply thrust, the tension spring will pull the movable second connecting block to move toward the first connecting block to complete the reset action.

[0014] In order to facilitate supporting the workpiece to be processed, the fixed bracket includes a first supporting frame and a second supporting frame, and there is a predetermined distance between the first supporting frame and the second supporting frame.

[0015] Beneficial effects: Compared with the prior art, the present invention realizes automatic feeding through a vibration plate and a direct vibration feeding device. The discharge device moves the suction cup through a lifting cylinder and a horizontal cylinder to suck the plug of the feeding port, and then sends the plug to the rotating operating mechanism, thereby realizing automatic discharge. The rotating operating mechanism aligns the plug with the pipe mouth through the rotating cylinder, and then drives the plug into the pipe mouth through the thrust cylinder. During the process, a second guide column is movably inserted in the first connecting block to prevent the second guide column from being offset when it is thrust by the thrust cylinder. A tension spring is also used to ensure that the plugging movable rod can be reset after completing one plugging action, waiting for the next plugging work. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] A plugging device for supporting round tubes comprises a frame, the upper end surface of the frame is provided with a frame bottom plate, the frame bottom plate is provided with a plugging mechanism, the frame bottom plate is provided with a plugging station, the plugging station is provided with a fixed bracket 6, the fixed bracket 6 is used to place a workpiece 8 to be processed, the workpiece 8 to be processed is a round tube; the fixed bracket 6 comprises a first support frame and a second support frame, and there is a predetermined distance between the first support frame and the second support frame.

[0023] The plugging mechanism includes a feeding mechanism, a discharging mechanism 4, and a rotating operating mechanism 5. The feeding mechanism, the discharging mechanism 4, and the rotating operating mechanism 5 are located on one side of the plugging station. A support plate 7 is provided on the other side of the plugging station. The discharging mechanism 4 is used to put the plugs sent by the feeding mechanism into the rotating operating mechanism 5. The feeding mechanism includes a vibration plate 1 and a direct vibration feeding device 3. One end of the direct vibration feeding device 3 is connected to the vibration plate 1 to feed the plugs arranged by the vibration plate 1 into the feeding port to wait for the discharging device to grab them.

[0024] The discharge mechanism 4 includes a suction cup, a lifting cylinder, and a horizontal cylinder. The floating joint of the horizontal cylinder is connected to the lifting cylinder through a first connecting plate, and the floating joint of the second cylinder is connected to the suction cup through a second connecting plate. The displacement of the suction cup is controlled by the lifting cylinder and the horizontal cylinder. The suction cup sucks the plug and moves it to the top of the plugging active rod 12 of the rotating operating mechanism 5, and then descends through the lifting cylinder to separate the suction cup from the plug.

[0025] The rotary operating mechanism 5 includes a rotary cylinder 15, a propulsion cylinder 2, and a reset mechanism. The rotary structure of the rotary cylinder 15 is connected to the rotary connection block 14. The front end surface of the rotary connection block 14 is fixedly connected to the linear bearing 13, and the upper end surface thereof is fixedly connected to the first connection block 16. The linear bearing 13 is movably sleeved with the plugging movable rod 12. The plugging movable rod 12 is fixedly connected to the second connection block 11. The second connection block 11 is fixedly connected to the second guide column 17. The second guide column 17 is movably arranged in the first connection block 16.

[0026] The motion trajectory of the floating joint of the propulsion cylinder 2 is parallel to the frame bottom plate, and the workpiece 8 placed on the fixed bracket 6 is also parallel to the frame bottom plate. The propulsion cylinder 2 is used to push the second guide column 17. The reset mechanism includes a first connecting bolt 18 and a second connecting bolt 9. The first connecting bolt 18 is connected to the first connecting block 16, and the second connecting bolt 9 is connected to the second connecting block 11. The two sides of the tension spring 10 are respectively connected to the first connecting bolt 18 and the second connecting bolt 9.

[0027] Workflow: The plugging mechanism has a waiting state and a plugging state. In the waiting state, the plugging movable rod 12 of the rotating operating mechanism 5 in the plugging mechanism is vertically upward waiting for the plug to be put in, and the horizontal cylinder of the discharge mechanism 4 is in an extended state, so that the vacuum suction cup is waiting for the plug to appear just above the discharge port of the feeding mechanism. When it is detected that the workpiece 8 to be processed is placed on the fixed bracket 6 on the plugging station, the plugging mechanism starts to act;

[0028] First, the lifting cylinder drives the vacuum suction cup to move downward to pick up the workpiece 8. After the vacuum suction cup finishes picking up the workpiece, the lifting cylinder moves upward to take out the plug from the feeding mechanism of the vibration plate 1. After the lifting cylinder moves upward to the right position, the horizontal cylinder contracts to take the plug to the top of the rotating operating mechanism 5. When the horizontal cylinder moves to the right position, the lifting cylinder moves downward to put the plug into the plugging movable rod 12.

[0029] During this series of actions, the vacuum suction cup always maintains the state of adsorbing the plug. When the plug is completely moved into the plugging movable rod 12, the vacuum suction cup cancels the adsorption action and separates from the plug. At this time, the plug is placed in the plugging piston rod.

[0030] Afterwards, the lifting cylinder moves upward to drive the vacuum suction cup to leave the rotating operating mechanism 5. When the lifting cylinder moves into place, the horizontal cylinder extends to move the vacuum suction cup to the plug of the feeding mechanism outlet again, preparing for the next plug removal.

[0031] When the vacuum suction cup puts the plug into the plugging piston rod and the vacuum suction cup is completely removed, the rotary cylinder 15 in the rotary operating mechanism 5 is actuated to flip the rotary operating mechanism 5 from the waiting state to the plugging state. When the rotary cylinder 15 is in place, the seventh cylinder extends out to push the plugging piston rod forward, pressing the plug in the plugging piston rod into the workpiece 8 to be processed, thereby completing the plugging.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
