Description

DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the accompanying drawings:

[0037] like Figure 1As shown, a fully automatic pipe sealing machine includes a frame 1 and a feeding mechanism 2, a pushing mechanism 3, a cleaning mechanism 4, a rotating mechanism 5, a heating mechanism 6 and a sealing mechanism 7 fixed on the frame 1, the feeding mechanism 2 corresponds to the left side of the pushing mechanism 3, the cleaning mechanism 4 and the rotating mechanism 5 correspond to the front side of the pushing mechanism 3 in sequence, and the heating mechanism 6 and the sealing mechanism 7 both correspond to the front side of the rotating mechanism 5.

[0038] The pipe to be sealed is put into the feeding mechanism 2, which automatically feeds the pipe and pushes the pipe to the side of the rotating mechanism 5 through the pushing mechanism 3. During the pushing process, the pipe passes through the cleaning mechanism 4, and the cleaning mechanism 4 cleans the oil on the outside of the pipe. The rotating mechanism 5 clamps the pipe and drives the pipe to rotate. The heating mechanism 6 heats and softens the end of the rotating pipe. Finally, the sealing mechanism 7 folds and seals the end of the pipe to complete the pipe sealing process.

[0039] like Figures 2 to 3 As shown, the feeding mechanism 2 includes a silo 21, a jacking drive assembly 22, a jacking platform 23, a material receiving platform 24, a top limit plate 25, a mounting crossbeam 26, a first lifting cylinder 27 and a side limit plate 28. A material storage cavity 211 is provided in the silo 21. The jacking drive assembly 22 is fixed on the frame 1. The jacking platform 23 is fixed to the power output end of the jacking drive assembly 22. The upper end of the jacking platform 23 passes through the bottom right side of the material storage cavity 211. The upper end surface of the jacking platform 23 is inclined downward along the right side. The material receiving platform 24 It is fixed on the right side of the silo 21, the left upper end surface of the material receiving platform 24 is tilted downward along the right side, and a boss 241 protruding upward is provided on the right side. The pushing mechanism 3 is used to push the workpiece on the material receiving platform 24. The top limit plate 25 is fixed on the right side of the silo 21 and there is a gap between the bottom and the left side of the material receiving platform 24. The mounting beam 26 is fixed on the silo 21, the first lifting cylinder 27 is fixed on the mounting beam 26, and the side limit plate 28 is fixed at the power output end of the first lifting cylinder 27 and corresponds to the right side of the top limit plate 25.

[0040] The operator places a batch of pipes in the storage chamber 211 in the silo 21, and the lifting drive assembly 22 drives the lifting platform 23 to rise, so that the pipes on the lifting platform 23 rise to the side of the receiving platform 24, and roll to the receiving platform 24 through the inclined surface at the upper end of the lifting platform 23, and stop after contacting the side limit plate 28. When it is necessary to feed the pipes to the subsequent process, the first lifting cylinder 27 drives the side limit plate 28 to rise, and the pipes slide down along the left side of the receiving platform 24 to the contact boss 241, and the pushing mechanism 3 pushes the pipes on the receiving platform 24 to the subsequent process. The top limit plate 25 can limit the diameter of the pipes reaching the receiving platform 24, avoid mistakenly loading pipes with larger diameters, and avoid overlapping and loading of multiple groups of pipes with the same diameter. This design can improve the accuracy of loading.

[0041] like Figures 4 to 5 As shown, the pushing mechanism 3 includes a Y-axis motor 31, a first slide plate 32, a first mounting bracket 33, a guide sleeve 34, a guide column 35, a first spring 36, a first sensor, a second mounting bracket 37, a first roller 38 and a push rod 39. The Y-axis motor 31 is fixed on the frame 1, the first slide plate 32 is fixed to the power output end of the Y-axis motor 31, the Y-axis motor 31 drives the first slide plate 32 to move forward and backward, the first mounting bracket 33 is slidably connected to the first slide plate 32, the guide sleeve 34 is fixed to the rear side of the first slide plate 32, the front end of the guide column 35 is fixed to the rear side of the first mounting bracket 33, and the rear end is passed through A guide sleeve 34 is provided, a first spring 36 is sleeved on the guide column 35 and both ends are fixedly connected to the front end of the guide sleeve 34 and the rear end of the first mounting bracket 33 respectively, a first sensor is fixed on the first slide plate 32, and is used to sense the position of the first mounting bracket 33, a second mounting bracket 37 is fixed above the frame 1, a first roller 38 is rotatably mounted on the upper end of the second mounting bracket 37, a rear end of a push rod 39 is fixed on the first mounting bracket 33, and a front end corresponds to the material receiving platform 24, a middle part of the push rod 39 is mounted on the first roller 38, and a plurality of groups of the second mounting bracket 37 and the first roller 38 are arranged along the Y-axis direction.

[0042] The loading mechanism 2 loads a group of pipes onto the receiving platform 24 and is on the left side of the boss 241. At this time, the Y-axis motor 31 drives the first slide 32 and the first mounting bracket 33 to move forward, that is, drives the push rod 39 to move forward, thereby pushing the pipe to move to the backward process. When the first slide 32 moves, it drives the first mounting bracket 33 to move through the first spring 36. When pipes accumulate on the receiving platform 24 and the push rod 39 cannot push the pipes forward, the first spring 36 is compressed and the first mounting bracket 33 moves backward relative to the first slide 32. When the relative movement of the first mounting bracket 33 and the first slide 32 reaches a certain distance, the first mounting bracket 33 is sensed by the first sensor, and the equipment stops running, reminding the operator to clean up the accumulated pipes to avoid damage to the pushing mechanism 3 and the equipment on the subsequent workstations.

[0043] like Figures 6 to 7 As shown, the cleaning mechanism 4 includes a third mounting bracket 41, a first rotating motor 42, a first gear 43, a second gear 44, a brush 45 and a protective cover 46.

The brush 45 is fixed in the mounting hole 441. The protective cover 46 is fixed on the third mounting bracket 41 and covers the outer periphery of the first gear 43 and the second gear 44.

[0044] There is usually a lot of oil stains on the periphery of metal pipes, and the oil stains on the periphery need to be cleaned. On the one hand, it is to avoid the accumulation of oil stains in the subsequent process and affect the processing accuracy. On the other hand, in order to maintain the cleanliness of subsequent workstations, when the pushing mechanism 3 pushes the pipe to the rotating mechanism 5, the pipe passes through the mounting hole 441, and the first rotating motor 42 drives the first gear 43 to rotate, thereby driving the second gear 44 to rotate continuously, and the brush 45 in the mounting hole 441 rotates continuously, thereby wiping the periphery of the pipe to remove the oil stains. In this design, the brush 45 can also be replaced by other objects that can remove oil stains, such as sponges, cotton, etc.

[0045] like Figures 8 to 9 As shown, the rotating mechanism 5 includes a second rotating motor 51, a fourth mounting bracket 52, a fixed chuck 53, a rotating auxiliary component 54 and a sensing component 55. The second rotating motor 51 and the fourth mounting bracket 52 are fixed above the frame 1, the fourth mounting bracket 52 corresponds to the front side of the cleaning mechanism 4, the fixed chuck 53 is rotatably mounted on the fourth mounting bracket 52 and is drivingly connected to the power output end of the second rotating motor 51, the second rotating motor 51 drives the fixed chuck 53 to rotate, the fixed chuck 53 is used to fix the workpiece, the rotating auxiliary component 54 is fixed on the frame 1 and corresponds to between the fixed chuck 53 and the cleaning mechanism 4, and the sensing component 55 is fixed at the front end of the fourth mounting bracket 52;

[0046] The rotation auxiliary component 54 includes a Y-axis slide 541, an adjustment base 542, a fifth mounting bracket 543, a sixth mounting bracket 544, a first roller 545, a first connecting block 546 and a second roller 547.

The two ends of the second spring 556 are respectively in contact with the head of the bolt 554 and the second connecting block 553. The second sensor 557 is fixed on the second connecting block 553 and corresponds to the front side of the bolt 554.

[0048] The pushing assembly pushes the pipe forward, and the pipe first passes over the top of the two sets of first rollers 545 and then enters the fixed chuck 53. At this time, the bolt 554 corresponds to the front side of the pipe. After the front end of the pipe contacts the head of the bolt 554, the bolt 554 is pushed to the end, and the second spring 556 is compressed until the front end of the bolt 554 contacts the second sensor 557 and stops. At this time, the pipe is transported to the required position. The limited position of the front end of the pipe can be changed by adjusting the plate 551. After the fixed chuck 53 clamps the pipe, the second lifting cylinder 552 The second connecting block 553 is driven to rise so that the bolt 554 no longer contacts the pipe. The bolt 554 is reset under the action of the second spring 556. Then, the second rotating motor 51 drives the fixed chuck 53 to rotate on the fourth mounting bracket 52, thereby driving the pipe to rotate. When the pipe is not rotating, the rear end of the pipe does not contact the second roller 547. When the pipe rotates at a high speed, the rear end of the pipe will shake and contact the second roller 547. Under the action of the second roller 547, the rear end of the pipe can be prevented from shaking too much.

[0050] After the pipe is clamped by the fixed chuck 53, the XY-axis drive assembly 61 drives the heating control box 62 and the heating coil 63 to move along the X-axis and Y-axis directions, so that the heating coil 63 is sleeved on the front end of the pipe and heats the pipe to soften the front end of the pipe so that the subsequent sealing mechanism 7 can seal the pipe.

The position is adjustable, a first tooth portion 7221 is provided at the rear end of the first rack 722, a second tooth portion 7231 is provided at the rear end of the second rack 723, the front sides of the first rack 722 and the second rack 723 are both flat, the first rotating column 724 can be rotatably mounted on the connecting frame 71, the third gear 726 is fixed on the first rotating column 724 and meshes with the first tooth portion 7221 and the second tooth portion 7231, the second rotating column 725 can be rotatably mounted on the connecting frame 71, the side of the second rotating column 725 contacts the front sides of the first rack 722 and the second rack 723, the folding assembly 73 is fixed on the upper end of the first rotating column 724 and corresponds to the left side of the connecting frame 71, and the hydraulic buffer 74 is fixed on the right side of the connecting frame 71.

[0052] The metal pipe is fixed by the fixed chuck 53 and rotated at high speed in the previous process. During the rotation of the metal pipe, the first motor 721 drives the first rack 722 and the second rack 723 to move in the left and right directions, thereby driving the third gear 726 to rotate. The third gear 726 drives the first rotating column 724 to rotate synchronously, so that the right end of the folding component 73 rotates around the upper end of the first rotating column 724. During the rotation, the folding component 73 folds the edge of the pipe inward. When the folding component 73 rotates to contact the hydraulic buffer 74, under the action of the hydraulic buffer 74, the rotation speed of the folding component 73 gradually decreases until it stops rotating. At this time, the sealing process of the end of the pipe is completed. The second rack 723 can adjust its position on the first rack 722, thereby adjusting the relative position of the first tooth portion 7221 and the second tooth portion 7231, and further adjusting the gap between the first rack 722 and the second rack 723 when they are meshing with the third gear 726, so as to reduce the gap and avoid insufficient transmission accuracy and excessive friction loss caused by excessive gap. The second rotating column 725 can limit the front end of the first rack 722 and the second rack 723 to avoid bending and deformation of the first rack 722 and the second rack 723. This design can make the equipment more stable and less lossy during operation, greatly improving the service life of the equipment.

[0053] The folding assembly 73 includes a first mounting base plate 731, a second motor 732, a first slide 733, a second slide plate 734, a second slide plate 735, a connecting plate 736 and a pressing block 737. The right end of the first mounting base plate 731 is fixed on the first rotating column 724, the second motor 732 is fixed on the left side of the first mounting base plate 731, the first slide plate 733 is fixed on the right side of the first mounting base plate 731, the bottom of the second slide plate 734 is slidably connected to the top of the first slide plate 733, the second slide plate 735 is fixed above the second slide plate 734 and fixedly connected to the power output end of the second motor 732, the left end of the connecting plate 736 is fixed on the second slide plate 735, the connecting plate 736 is adjustable in the front-rear direction on the second slide plate 735, and the pressing block 737 is cylindrical and can be rotatably mounted on the right end of the connecting plate 736.

[0054] When the pipe rotates at high speed, the second motor 732 first drives the second slide plate 734 and the second slide 735 to slide on the first slide 733 along the right side, so that the pressure block 737 is close to the end of the pipe, and then drives the first mounting base plate 731 to rotate around the first rotating column 724 through the rotating drive component 72, so that the side of the pressure block 737 contacts the end of the pipe and folds the end of the pipe inward. By adjusting the front and rear direction position of the connecting plate 736 on the second slide 735, the position of the pressure block 737 can be fine-tuned to adapt to different processing requirements.

[0055] In the present design, the sealing mechanism 7 also includes a material unloading auxiliary component 75, which includes a material unloading track 751, a first connecting bracket 752, a third lifting cylinder 753, a second connecting bracket 754 and a second roller 755. A material unloading trough 7511 is provided above the material unloading track 751. The rear end of the material unloading track 751 is fixed above the first rotating column 724. The front end of the material unloading track 751 is tilted downward. The first connecting bracket 752 is fixed to the front end of the connecting frame 71. The third lifting cylinder 753 is fixed to the first connecting bracket 752. The second connecting bracket 754 is fixed to the power output end of the third lifting cylinder 753. The second roller 755 can be rotatably mounted on the second connecting bracket 754. The second roller 755 corresponds to the front end of the material unloading track 751.

[0056] After the folding assembly 73 folds the end of the metal pipe, the folding assembly 73 is reset. At this time, the unloading track 751 is below the pipe and the unloading trough 7511 is just below the central axis of the pipe. After the chuck in the previous process stops rotating and releases the pipe, the pipe is pushed out of the chuck through the pushing mechanism 3 of the previous process and falls into the unloading trough 7511 for unloading. When the processed pipe is long, the pipe cannot be completely dropped into the unloading track 751 for unloading. Moreover, after the long pipe is separated from the chuck and touches other parts below, the end of the long pipe is tilted and hits the surrounding parts, affecting the normal operation of production. Therefore, when unloading the long pipe, the third lifting cylinder 753 first drives the second connecting bracket 754 to rise, and the pipe is then pushed out by the pushing mechanism 3. The front end of the pipe can be placed on the second roller 755. When the pipe is separated from the chuck, the pipe slides to the subsequent process through the second roller 755 to avoid collision between the pipe and surrounding parts.

[0057] In the present design, the sealing mechanism 7 also includes a frame adjustment assembly 76, which includes a second mounting base plate 761, a third connecting bracket 762, a rotating shaft rod 763, a hand wheel 764 and a connecting shaft rod 765. The second mounting base plate 761 is fixed to the front end of the frame 1, the bottom of the connecting frame 71 is slidingly connected to the upper right side of the second mounting base plate 761, the third connecting bracket 762 is fixed to the left side of the second mounting base plate 761, the middle part of the rotating shaft rod 763 is threadedly connected to the third connecting bracket 762, the hand wheel 764 is fixed to the left end of the rotating shaft rod 763, the right end of the rotating shaft rod 763 can be rotatably mounted on the left end of the connecting shaft rod 765, and the right end of the connecting shaft rod 765 is fixed to the left side of the connecting frame 71.

[0058] By turning the hand wheel 764 , the rotating shaft 763 is rotated and moved in the left-right direction, so that the connecting frame 71 is driven to move through the connecting shaft 765 , thereby adjusting the position of the connecting frame 71 .

[0059] The working principle of this embodiment:

[0060] The pipe to be sealed is put into the feeding mechanism 2, which automatically feeds the pipe and pushes the pipe to the side of the rotating mechanism 5 through the pushing mechanism 3. During the pushing process, the pipe passes through the cleaning mechanism 4, and the cleaning mechanism 4 cleans the oil on the outside of the pipe. The rotating mechanism 5 clamps the pipe and drives the pipe to rotate. The heating mechanism 6 heats and softens the end of the rotating pipe. Finally, the sealing mechanism 7 folds and seals the end of the pipe to complete the pipe sealing process.

[0061] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
