DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention will be further described below in conjunction with the embodiments.

[0037] Example 1: Reference Figures 1 to 9 The integrated conical cylinder intelligent overmolding device includes a base 1, an upper clamping mechanism 2 fixed on the base 1 and a supporting bracket 4 fixed on the upper clamping mechanism 2, a hydraulic mechanism 3 fixed on the upper clamping mechanism 2, and a lower clamping mechanism 5 fixed on the upper clamping mechanism 2.

[0038] It should be noted that by placing the bent conical cylinder on the support bracket 4, the processing and forming work can be carried out in the device. Before welding, the conical cylinder needs to be clamped by the upper clamping mechanism 2 and the lower clamping mechanism 5, and during the clamping process, it is supported internally to better ensure the coaxiality of the cylinder and the uniformity of the butt gap, thereby ensuring the subsequent welding effect, and the hydraulic mechanism 3 can also be used to drive the movement of the welding workpiece after completing the clamping work.

[0039] Further explanation, in order to hydraulically drive the movement of components in the device, such as Figure 2 As shown, the hydraulic mechanism 3 includes a hydraulic oil tank 31 filled with hydraulic oil, an electric cylinder 32 is fixed at one end of the hydraulic oil tank 31, a piston plate located in the hydraulic oil tank 31 is fixed at the output end of the electric cylinder 32, the hydraulic oil tank 31 is connected to a circulation rack 33, and the circulation rack 33 is connected to an adjustment component 35. By starting the electric cylinder 32 to push the piston plate therein to move, the piston plate can push the hydraulic oil to flow, and then flow into the adjustment component 35 through the circulation rack 33.

[0040] Furthermore, in order to be able to drive the welding workpiece after clamping, such as Figure 3 As shown, the adjustment component 35 includes a sealing box 351 fixed to the lower end of the circulation rack 33, arc holes 352 are symmetrically opened on both sides of the sealing box 351, and an open hole is opened on one side of the sealing box 351 and between the two arc holes 352. Two indirectly driven sealing plates 354 are slidably connected in the sealing box 351. When the device is in an initial state, the two sealing plates 354 are in contact with each other. When the two symmetrically opened arc holes 352 are in an airtight blocking state, the open hole will maintain airtight communication, that is, the two symmetrically opened arc holes 352 are respectively connected to the hydraulic pipe 22 and the two fixed pipes 52, and the open hole can be connected to the welding workpiece by a pipeline and an interface. When the device needs to be clamped, that is, in the initial state, the two symmetrical arc holes 352 maintain airtight communication, so that the hydraulic oil in the sealing box 351 is used for clamping work, and when the clamping is completed, the two symmetrical arc holes 352 will become airtightly blocked, and the hydraulic oil in the sealing box 351 can drive the welding workpiece through the pipeline;

[0041] Then, the inner cavity of the sealing box 351 is rotatably connected with two threaded rods 353, and the threaded rods 353 are threadedly connected to the sealing plate 354. The thread directions of the two threaded rods 353 are opposite. When the two threaded rods 353 rotate in the same direction, the two sealing plates 354 will move in opposite directions. Three mutually meshing bevel gears 355 are arranged in the sealing box 351. Two symmetrical bevel gears 355 are respectively fixedly connected to the threaded rods 353 on the same side, and the other bevel gear 355 is connected with the stepping motor 567 with transmission. When the device is clamping, the stepping motor 567 needs to be started. During this process, the stepping motor 567 will drive the three bevel gears 355 to rotate at the same time. Under the action of the threaded connection, the two sealing plates 354 will move in the direction away from each other, so that the two symmetrically opened arc holes 352 are airtightly blocked, and the other arc hole 352 will also become airtightly connected.

[0042] It should be noted that when the device performs the clamping work, the electric cylinder 32 is started to push the piston plate therein to move, and the piston plate can push the hydraulic oil in the hydraulic oil tank 31 to flow. The hydraulic oil will flow into the sealing box 351 through the circulation rack 33, and then flow into the hydraulic pipe 22 and the fixed pipe 52 through two symmetrically opened arc holes 352 and pipelines. When the device completes the clamping work, the three bevel gears 355 in the sealing box 351 are indirectly driven to rotate, and the two threaded rods 353 will rotate with the bevel gears 355, driving the two sealing plates 354 to move away from each other, thereby hermetically sealing the two symmetrically opened arc holes 352.

[0043] Further explanation, in order to cooperate with the lower clamping mechanism 5 to perform the clamping work, as Figure 4 As shown, the upper clamping mechanism 2 includes a supporting wall 21 fixed on the base 1, and the upper end of the supporting wall 21 is rotatably connected to the hydraulic pipe 22, the hydraulic pipe 22 is communicated with the sealing box 351, the hydraulic pipe 22 is driven by a motor and a gear, a hollow bracket 23 is fixed to the upper end of the hydraulic pipe 22, and two hydraulic rods 24 communicated with the hydraulic pipe 22 are fixed to the lower end of the hollow bracket 23, and an upper clamping plate 25 is fixed to the telescopic end of the hydraulic rod 24. The hydraulic oil flowing into the hydraulic pipe 22 will enter the two hydraulic rods 24 through the hollow bracket 23, and then push the upper clamping plate 25 to move downward. When the upper clamping plate 25 contacts the upper end of the conical cylinder, it will clamp it. In order to facilitate loading and unloading, the upper clamping plate 25 is not located above the supporting bracket 4 when the device is not in use, and can be adjusted by manual rotation.

[0044] To further explain, in order to cooperate with the clamping mechanism 2 to complete the clamping work, as Figure 5 and Figure 6As shown, the lower clamping mechanism 5 includes a fixed bottom plate 51, and two fixed tubes 52 communicating with the sealing box 351 are fixed on the upper end of the fixed bottom plate 51. The inner cavity of the fixed tube 52 is slidably connected to a movable tube 53, and the inner cavity of the movable tube 53 is slidably connected to a piston rod 54. The upper end of the piston rod 54 is fixed with a lower clamping plate 55. When the hydraulic oil flows into the fixed tube 52, it will first enter the movable tube 53 to push the piston rod 54 to move upward. In order to prevent the conical cylinder from being damaged, the lower clamping plate 55 and the upper clamping plate 2 When the clamping force is too large, the hydraulic oil entering the movable tube 53 will flow back into the fixed tube 52, so that the movable tube 53 will move upward while the piston rod 54 and the lower clamping plate 55 remain at the same height. That is to say, when the lower clamping plate 55 and the upper clamping plate 25 contact the conical tube at the same time, the support bracket 4 has elasticity, which can ensure that the upper clamping plate 25 will not squeeze the conical tube excessively, and the lower clamping plate 55 will no longer move upward due to the movable tube 53, thus ensuring the integrity of the conical tube;

[0045] Then, a driving assembly 56 is provided between the lower clamping plate 55 and the fixed base plate 51, a telescopic fixing rod 50 is fixed to the upper end of the fixed base plate 51, a conical block 57 is fixed to the upper end of the telescopic fixing rod 50, the output end of the telescopic fixing rod 50 is connected to the lower clamping plate 55, a supporting plate 58 is fixed to the upper end of the lower clamping plate 55, a plurality of limit blocks 59 are slidably connected to the upper end of the support plate 58, and the limit blocks 59 move downward and move away from each other. When the device is performing the clamping work, the support plate 58 and the limit blocks 59 therein will move downward with other components, but the conical block 57 will always remain unchanged, and when the plurality of limit blocks 59 move a certain distance in the direction away from each other, they will contact the inner wall of the conical cylinder, and cooperate with the upper clamping plate 25 and the lower clamping plate 55 to better complete the clamping work.

[0046] Further explanation: In order to ensure the coaxiality and uniformity of the butt clearance of the conical cylinder, Figure 7 and Figure 8As shown, the driving assembly 56 includes a connecting tube 561 located below the lower clamping plate (55), the upper and lower ends of the connecting tube 561 are rotatably connected to threaded tubes 562, the support plate 58 is threadedly connected to the threaded tube 562 located on the upper side, the inner walls of the two threaded tubes 562 are both provided with open grooves, the surface of the threaded tube 562 located on the lower side is threadedly connected to a threaded rack 563, the inner wall array of the threaded rack 563 is rotatably connected to a plurality of connecting rods 564, the upper ends of the connecting rods 564 are rotatably connected to a movable block 565, the surface of the lower clamping plate 55 is threadedly connected to the threaded tube 562, and the threaded rack 563 is threadedly connected to the threaded rack 563. The surface is slidably connected with a plurality of clamping frames 566, which are fixedly connected to the movable block 565 located on the same side. A fixed stepping motor 567 is provided at the lower end of the fixed bottom plate 51, and a threaded rod 568 is fixed to the output end of the stepping motor 567. A rectangular groove is symmetrically provided on the surface of the threaded rod 568. Two telescopic rods are fixed to the lower end of the lower clamping plate 55, and a threaded ring 560 is fixed to the lower end of the telescopic rod. The threaded ring 560 is threadedly connected to the threaded rod 568, and the lower end of the threaded ring 560 is slidably connected to two telescopic blocks 569.

[0047] Then, when the stepper motor 567 drives the threaded rod 568 to rotate, the threaded ring 560 and the two telescopic blocks 569 threadedly connected to the surface thereof will be driven to move downward, and the telescopic blocks 569 will be driven to rotate by the rectangular groove while moving downward, that is, when the stepper motor 567 is started, the telescopic blocks 569 will drive the two threaded tubes 562 to rotate from top to bottom in sequence while moving downward, and when the threaded tube 562 located on the upper side rotates, it will drive the support plate 58 to move downward, ensuring that the limit block 59 can contact the inner wall of the conical cylinder, and when the threaded tube 562 located on the lower side rotates, it will drive the threaded frame 563 and the threaded frame 563 to move downward, so that the multiple connecting rods 564 and the clamping frame 566 move in a direction close to each other, and finally the multiple clamping frames 566 will fit on the surface of the conical cylinder, and cooperate with the support plate 58 contacting the inner wall of the conical cylinder to ensure that the coaxiality and docking gap of the conical cylinder are uniform;

[0048] It should be noted that after the upper clamping plate 25 and the lower clamping plate 55 complete the clamping of the conical tube, the stepper motor 567 is started to drive the threaded rod 2 568 to rotate, which will drive the threaded ring 560 and the two telescopic blocks 569 connected to the surface of the threaded rod to move downward. The telescopic block 569 will be driven by the rectangular groove to rotate while moving downward, and then the threaded tube 562 on the upper side will be driven to rotate, so that the support plate 58 and the limit block 59 move downward, but the conical block 57 remains unchanged. When the support plate 58 moves downward, it will move in a direction away from each other, and after moving a certain distance, it will contact the inner wall of the conical tube, and then the telescopic block 569 will continue to move downward. When it moves to the threaded tube 5 After being inserted into the conical tube 62, it can drive the threaded tube 562 located on the lower side to rotate, and the rotating threaded tube 562 will drive the threaded frame 563 and the connecting rod 564 to move downward, so that the multiple movable blocks 565 and the clamping frame 566 move in the direction of approaching each other, and finally the multiple clamping frames 566 will fit on the surface of the conical tube to complete the entire clamping work. During this process, the stepping motor 567 will drive the three bevel gears 355 to rotate at the same time. Under the action of the threaded connection, the two sealing plates 354 will move in the direction of moving away from each other. When the telescopic block 569 moves to the bottom, the two symmetrically opened arc holes 352 are airtightly blocked. Starting the electric cylinder 32 again can allow the hydraulic oil in the sealing box 351 to drive the welding workpiece to move through the pipeline.

[0049] The working principle of the present invention is as follows: the bent conical cylinder is placed on the supporting bracket 4, the gear drives the hydraulic pipe 22 to rotate so that the upper clamping plate 25 is located above the supporting bracket 4, and the electric cylinder 32 is started to push the piston plate therein to move. The piston plate can push the hydraulic oil in the hydraulic oil tank 31 to flow, and the hydraulic oil will flow into the sealing box 351 through the circulation rack 33, and then flow into the hydraulic pipe 22 and the fixed pipe 52 through two symmetrically opened arc holes 352 and pipelines. The hydraulic oil flowing into the hydraulic pipe 22 will enter the two hydraulic rods 24 through the hollow bracket 23, and then push the upper clamping plate 25 to move downward. When the hydraulic oil flows into the fixed pipe 52, it will first enter the movable pipe 53 to push the piston rod 54 to move upward. The piston rod 54 will drive the lower clamping plate 55 to move upward at the same time. When the upper clamping plate 25 and the lower clamping plate 55 contact the conical cylinder at the same time, the preliminary clamping work is completed.

[0050] In order to prevent the conical tube from being damaged, when the clamping force between the lower clamping plate 55 and the upper clamping plate 25 is too large, the hydraulic oil entering the movable tube 53 will flow back into the fixed tube 52, so that the piston rod 54 and the lower clamping plate 55 maintain the same height, and the movable tube 53 will move upward. That is to say, after the lower clamping plate 55 and the upper clamping plate 25 contact the conical tube at the same time, the support bracket 4 therein has elasticity, which can ensure that the upper clamping plate 25 will not excessively squeeze the conical tube, and the lower clamping plate 55 will no longer move upward due to the movable tube 53, thus ensuring the integrity of the conical tube, so that it will not be deformed by a great force, which is convenient for the subsequent alignment welding work;

[0051] After the upper clamping plate 25 and the lower clamping plate 55 complete the clamping of the conical cylinder, the stepper motor 567 is started to drive the threaded rod 2 568 to rotate, which will drive the threaded ring 560 and the two telescopic blocks 569 connected to the surface of the threaded rod to move downward. The telescopic block 569 will be driven by the rectangular groove to rotate while moving downward, and then the threaded tube 562 on the upper side will be driven to rotate, so that the support plate 58 and the limit block 59 move downward, but the conical block 57 remains unchanged. When the support plate 58 moves downward, The plurality of movable blocks 565 and the clamping frames 566 move in a direction away from each other, and after moving a certain distance, they contact the inner wall of the conical tube, and then the telescopic block 569 continues to move downward, and after moving into the threaded tube 562 located at the lower side, it can drive the threaded tube 562 located at the lower side to rotate, and the rotating threaded tube 562 drives the threaded frame 563 and the connecting rod 564 to move downward, so that the plurality of movable blocks 565 and the clamping frames 566 move in a direction close to each other, and finally the plurality of clamping frames 566 are attached to the surface of the conical tube, completing the entire clamping work;

[0052] During this process, the stepper motor 567 will drive the three bevel gears 355 to rotate simultaneously. Under the action of the threaded connection, the two sealing plates 354 will move away from each other. When the telescopic block 569 moves to the bottom, the two symmetrically opened arc holes 352 are hermetically sealed. Starting the electric cylinder 32 again can allow the hydraulic oil in the sealing box 351 to drive the welding workpiece to move through the pipeline, allowing the conical cylinder to complete the welding work.
