Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically to a semi-automatic plugging device for long pipes. Background Technology

[0002] Currently, in the processing of metal pipe fittings, long pipes that require plugging are often plugged manually. This not only requires a large amount of space for handling, but also results in a serious waste of time due to the back-and-forth handling of semi-finished products, leading to a high workload for employees.

[0003] Pipe plugging equipment is a type of mechanical device specifically designed to install plugs at the ends of pipe fittings. It is widely used in construction, transportation, energy, and other fields. However, existing plugging equipment mostly performs plugging on one end of long pipes. Some long pipes require plugging at both ends, necessitating two plugging operations rather than completing the process in one go. Therefore, designing a semi-automatic plugging device for long pipes is meaningful. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, the purpose of this invention is to provide a semi-automatic plugging device for long pipes, so as to solve the problem of simultaneously and automatically plugging both ends of long pipes.

[0005] This utility model is achieved through the following technical solution:

[0006] A semi-automatic plugging device for long pipes includes a worktable, a vibrating discharge mechanism, a transfer mechanism, a rotating mechanism, a plugging mechanism, and a rotary cylinder. The vibrating discharge mechanism, transfer mechanism, rotating mechanism, plugging mechanism, and rotary cylinder are arranged in pairs and symmetrically at both ends of the worktable. The plugging mechanism includes a plugging cylinder, a push rod, a movable block, a rotating shaft, a guide block, and a fixed seat. The cylinder body of the plugging cylinder and the bottom of the fixed seat are both located on the worktable. The top of the fixed seat is horizontally mounted with a rotating shaft via a bearing. The rotating shaft clamps and fixes the guide block. The telescopic end of the plugging cylinder is fixed with a push rod. The movable block passes through a guide groove opened in the center of the guide block. One end of the block is equipped with a positioning cylinder and a stop, and the other end of the movable block is equipped with a baffle. After the plugging accessory is transported to the transfer mechanism by the vibration discharge mechanism, the transfer mechanism moves it above the movable block. The rotation mechanism drives the rotating shaft to rotate, so that the movable block rotates from the horizontal position to the vertical position. At this time, the transfer mechanism releases the plugging accessory and lets it enter the positioning cylinder. After that, the rotation mechanism drives the movable block to return to the horizontal position. The push rod pushes the baffle to make the movable block move along the guide groove to one end of the long tube for plugging. During plugging, the long tube is pressed by the rotating cylinder. After plugging is completed, the rotation mechanism drives the movable block to return to the vertical position.

[0007] Preferably, a fixed base plate and a movable base plate are respectively installed at both ends of the workbench. The fixed base plate is fixed to one end of the workbench, and the movable base plate is slidably installed on the other end of the workbench. The cylinder bodies and the bottom of the fixed seats of one set of transfer mechanism, rotation mechanism, rotation cylinder, and stopper cylinder are all installed on the fixed base plate, and the cylinder bodies and the bottom of the fixed seats of the other set of transfer mechanism, rotation mechanism, rotation cylinder, and stopper cylinder are all installed on the movable base plate. The distance between the fixed base plate and the movable base plate is adjusted according to the pipe size, and then the movable base plate is fixed with positioning blocks.

[0008] Preferably, the vibratory discharge mechanism is installed in pairs and symmetrically at both ends of the same side of the workbench. It includes a vibratory plate, a discharge channel and a lifting cylinder. The vibratory plate discharges the parts to be plugged through the discharge channel. After the parts to be plugged reach the channel port, they are pushed out by the lifting cylinder to the bottom of the transfer mechanism.

[0009] Preferably, the transfer mechanism includes a column, a slide rail, a lifting cylinder, a chuck, a slider, and a horizontal cylinder. In one set of transfer mechanisms, the column is fixed to a fixed base plate, and in the other set of transfer mechanisms, the column is fixed to a movable base plate. The top of the column is horizontally mounted with the slide rail. The cylinder body of the lifting cylinder is fixed to the slider. The cylinder body of the horizontal cylinder is fixed to one end of the slide rail, and its telescopic end is connected to the cylinder body of the lifting cylinder. The telescopic end of the lifting cylinder is provided with a chuck. The slider cooperates with the slide rail. After the chuck clamps the part to be plugged, it moves it above the movable block.

[0010] Preferably, the rotating mechanism includes a telescopic cylinder, a second slider, a second slide rail, a rack, and a gear. The second slider is configured to cooperate with the second slide rail. A rack is fixed to the top of the second slider, and the rack meshes with the gear. The gear is mounted on a rotating shaft. The telescopic end of the telescopic cylinder can push the second slider to move horizontally. After the plugging accessory enters the positioning cylinder, the telescopic cylinder actuates to reset the movable block to a horizontal position. After plugging is completed, the telescopic cylinder actuates to reset the movable block to a vertical position. In one set of rotating mechanisms, the telescopic cylinder and the second slide rail are fixed to a fixed base plate, and in the other set of rotating mechanisms, the telescopic cylinder and the second slide rail are fixed to a movable base plate.

[0011] Preferably, the movable block has sliders on both sides, and the guide groove in the guide block has a sliding groove on its inner wall, and the slider slides in the sliding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, by designing two sets of vibrating discharge mechanisms, transfer mechanisms, rotating mechanisms, plugging mechanisms, and rotary cylinders on both sides of the workbench, can automatically plug both ends of a long tube simultaneously. Its most significant features are: within a limited space and with minimal cost, the plugging of both ends of a long tube can be completed simultaneously; and while the work is being completed, employees only need to perform the actions of picking up and placing the tube, greatly reducing the workload of employees and improving plugging efficiency.

[0014] 2. This utility model allows for the replacement of different plugging accessories in the vibrating discharge mechanism at both ends as needed, with different accessories inserted into both ends of the pipe. Since a fixed base plate and a movable base plate are installed at both ends of the worktable, the distance between the fixed base plate and the movable base plate can be adjusted according to the length of the pipe to achieve the appropriate plugging distance.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0024] Figure 1-5 A semi-automatic plugging device for long tubes is shown, including a worktable 1, a vibrating discharge mechanism 3, a transfer mechanism 4, a rotating mechanism 5, a plugging mechanism 6, and a rotary cylinder 8. The vibrating discharge mechanism 3, the transfer mechanism 4, the rotating mechanism 5, the plugging mechanism 6, and the rotary cylinder 8 are arranged in pairs and symmetrically at both ends of the worktable 1.

[0025] The plugging mechanism 6 includes a plugging cylinder 61, a push rod 62, a movable block 63, a rotating shaft 64, a guide block 65, and a fixed seat 66. The cylinder body of the plugging cylinder 61 and the bottom of the fixed seat 66 are both mounted on the worktable 1. The top of the fixed seat 66 is horizontally mounted on the rotating shaft 64 via bearings. The rotating shaft 64 clamps and fixes the guide block 65. The extension end of the plugging cylinder 61 is fixed with the push rod 62. The movable block 63 passes through a guide groove 6501 opened in the center of the guide block 65. One end of the movable block 63 is provided with a positioning cylinder 6301 and a stop 6302, and the other end of the movable block 63 is provided with a baffle 6303. The plugging parts are... After being transported to the transfer mechanism 4 by the vibrating discharge mechanism 3, the 9 is moved above the movable block 63. The rotating mechanism 5 drives the rotating shaft 64 to rotate, so that the movable block 63 rotates from the horizontal position to the vertical position. At this time, the transfer mechanism 4 releases the plugging accessory 9 so that it enters the positioning cylinder 6301. After that, the rotating mechanism 5 drives the movable block 63 to return to the horizontal position. The push rod 62 pushes the baffle 6303 so that the movable block 63 moves along the guide groove 6501 to one end of the long tube 10 for plugging. During plugging, the rotating cylinder 8 presses the long tube 10. After plugging is completed, the rotating mechanism 5 drives the movable block 63 to return to the vertical position.

[0026] To accommodate the need for plugging pipes of varying lengths, in one embodiment of this invention, a fixed base plate 2 and a movable base plate 7 are respectively installed at both ends of the workbench 1. The fixed base plate 2 is fixed to one end of the workbench 1, and the movable base plate 7 is slidably installed on the other end of the workbench 1. One set of transfer mechanisms 4, rotation mechanisms 5, rotation cylinders 8, and the cylinder bodies and bottoms of the plugging cylinder 61 are all mounted on the fixed base plate 2. The other set of transfer mechanisms 4, rotation mechanisms 5, rotation cylinders 8, and the cylinder bodies and bottoms of the plugging cylinder 61 are all mounted on the movable base plate 7. The distance between the fixed base plate 2 and the movable base plate 7 is adjusted according to the pipe size, and then the movable base plate 7 is fixed in place using a positioning block 11. This allows for adjustment of the plugging distance, achieving a multi-functional machine.

[0027] The vibrating discharge mechanism 3 is installed in pairs and symmetrically at both ends of the same side of the workbench 1. It includes a vibrating plate 31, a discharge channel 32 and a lifting cylinder 33. The vibrating plate 31 discharges the plugged part 9 through the discharge channel 32. After the plugged part 9 reaches the channel port, it is pushed out by the lifting cylinder 33 to the bottom of the transfer mechanism 4.

[0028] The transfer mechanism 4 is divided into two groups, left and right. Each group of transfer mechanisms 4 includes a column 41, a slide rail 42, a lifting cylinder 43, a claw 44, a slider 45, and a horizontal cylinder 46. The column 41 in one group of transfer mechanisms 4 is fixed on the fixed base plate 2, and the column 41 in the other group of transfer mechanisms 4 is fixed on the movable base plate 7. The top of the column 41 is horizontally mounted with the slide rail 42. The cylinder body of the lifting cylinder 43 is fixed on the slider 45. The cylinder body of the horizontal cylinder 46 is fixed to one end of the slide rail 42, and its telescopic end is connected to the cylinder body of the lifting cylinder 43. The telescopic end of the lifting cylinder 43 is equipped with a claw 44. The slider 45 is configured to cooperate with the slide rail 42. After the claw 44 clamps the plugging accessory 9, it moves it above the movable block 63. After the plugging part 9 is ejected by the lifting cylinder 33, it is clamped by the chuck 44. Then, the lifting cylinder 43, the slider 45, and the horizontal cylinder 46 work together to move the plugging part 9 from position A to position B, and begin the next process. It is worth mentioning that the chuck 44 here can be a commonly used gripper cylinder.

[0029] The rotating mechanism 5 is divided into left and right groups. Each group of rotating mechanisms 5 includes a telescopic cylinder 51, a second slider 52, a second slide rail 53, a rack 54, and a gear 55. The second slider 52 is configured to cooperate with the second slide rail 53. The top of the second slider 52 is fixed with a rack 54, which meshes with the gear 55. The gear 55 is mounted on the rotating shaft 64. The telescopic end of the telescopic cylinder 51 can push the second slider 52 to move horizontally. After the plugging accessory 9 enters the positioning cylinder 6301, the telescopic cylinder 51 is activated, causing the movable block 63 to return to the horizontal position. After plugging is completed, the telescopic cylinder 51 is activated, causing the movable block 63 to return to the vertical position. The telescopic cylinder 51 and the second slide rail 53 in one group of rotating mechanisms 5 are fixed on the fixed base plate 2, while the telescopic cylinder 51 and the second slide rail 53 in the other group of rotating mechanisms 5 are fixed on the movable base plate 7. When the telescopic cylinder 51 starts working, it pushes the second slider 52 to slide on the second slide rail 53, causing the rack 54 to move horizontally. The horizontal movement of the rack 54 drives the gear 55 to rotate. Through the rotation of the gear, the movable block 63 is rotated from the horizontal position to the vertical position. At this time, the pawl 44 in position B releases the plugging accessory 9, allowing it to enter the positioning cylinder 6301 on the movable block 63. Afterwards, through the rotation of the gear, the movable block 63 is rotated from the vertical position to the horizontal position to reset. Then, the telescopic end of the plugging cylinder 61 moves forward, pushing the movable block 63 forward along the guide groove 6501 of the guide block 65 to perform plugging. During plugging, the rotary cylinder 8 presses the long tube 10. After plugging is completed, the movable block 63 is rotated from the horizontal position to the vertical position again through the rotation of the gear to reset. This process is repeated to improve efficiency.

[0030] The movable block 63 has sliders 6304 on both sides, and the guide groove 6501 in the guide block 65 has a sliding groove 65011 on its inner wall, and the slider 6304 slides in the sliding groove 65011.

[0031] It is worth mentioning that the long pipe 10 mentioned above can be a long crossbeam or other pipe. Whether the pipe is single-ended or double-ended, it can be plugged. This utility model can be applied to double-ended plugging of various specifications of pipes. The plugging accessories on the left and right sides can also be designed differently according to actual needs. Correspondingly, the positioning cylinders on both sides match the corresponding plugging accessories. Then, the plugging distance at both ends is adjusted to perform double-ended plugging simultaneously.

[0032] The working principle of this utility model:

[0033] After the long tube 10 is placed at the workpiece's fixed position, the rotary cylinder 8 starts to press the long tube 10. The plugging accessory 9 from the vibratory plate 31 reaches the port, and the chuck 44 clamps the plugging accessory 9, transferring it from position A to position B. The chuck 44 is released, and the plugging accessory 9 falls onto the positioning cylinder 6301 of the movable block 63. At this time, the telescopic cylinder 51 starts, pushing the slider 52 to slide horizontally. Through the action of the rack 54 and gear 55, the movable block 63 rotates from a vertical position to a horizontal position. Then, the telescopic end of the plugging cylinder 61 moves forward to plug the accessory. After completion, the movable block 63 returns to the vertical position. This reciprocating action achieves continuous plugging.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
