DETAILED DESCRIPTION

[0016] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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.

[0017] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0018] A propulsion mechanism used between an intermediate frequency furnace and a constant temperature furnace, including a conveying device located between the intermediate frequency furnace and the constant temperature furnace, a propulsion mechanism is installed above the conveying device, the conveying device includes a bracket 1 and a roller 2 installed on the bracket 1, and the roller 3 is connected to the sprocket by a motor through a reducer. The chain drive is suitable for this occasion because it can work under harsh high temperature conditions and transmits large power. A double-head coupling is used, that is, sprockets are installed on both sides of the shaft, and the chain shafts are connected to each other, so the roller 2 of the entire output mechanism can move synchronously, saving the number of motors. The roller 2 design should be arc-shaped, because the barrel is cylindrical, this design can ensure that the barrel is exactly in the center position on the conveying line, that is, it has good centering, ensuring that the barrel is not skewed during transportation.

[0019] The propulsion mechanism comprises a rack, the rack comprises an upper rack 4 and a lower rack, and the propulsion assembly is mounted on the upper rack 4 .

[0020] The pushing mechanism is generally close to the medium frequency furnace, and the No. 2 gear 19 is rotated under the drive of the servo motor 20. The No. 2 gear 19 and the No. 2 rack 18 cooperate to drive the push-pull rod 14 to extend, and the hook at the top of the push-pull rod 14 is inserted into the nut in front of the barrel. Under the action of the square motor 15, the push-pull rod 14 is driven to rotate slowly, so that the hook and the nut are locked. After completing this operation, the push-pull rod 14 is used to drive the barrel to move linearly under the drive of the servo motor 20, and the barrel is brought above the roller 3 with the roller wheel 2. The displacement cylinder 7 extends to separate the upper rack 4 and the lower rack, so that the barrel can be pushed to the entrance of the constant temperature furnace under the action of the roller 3 with the roller wheel 2, but the roller 3 cannot completely send the barrel in. At this time, the displacement cylinder 7 retracts, and the barrel is pushed into the constant temperature furnace through the other end of the push-pull rod 14 and in cooperation with the servo motor 20.

[0021] The lower rack includes a left lower rack 5 and a right lower rack 6. Both the left lower rack 5 and the right lower rack are equipped with displacement cylinders 7. The output ends of the displacement cylinders 7 are respectively connected to the two ends of the upper rack 4 to drive it to move up and down.

[0022] A slide groove 8 is installed on one side of the bracket 1, and a No. 1 rack 9 is installed on the other side of the bracket 1. The lower left shelf 5 is provided with a slider 10 that slides with the slide groove 8, and the lower right shelf 6 is provided with a motor seat 11. The motor seat 11 is installed with a worm gear reducer 12. The drive shaft of the worm gear reducer 12 is installed with a No. 1 gear 13. The No. 1 gear 13 cooperates with the No. 1 rack 9 to move. The worm gear reducer 12 drives the No. 1 gear 13 to move back and forth on the No. 1 rack 9, and at the same time drives the slider 10 to move back and forth in the slide groove 8. The displacement of the two drives the entire propulsion mechanism to move linearly on the bracket 1.

[0023] The propulsion assembly includes a push-pull rod 14 , a square motor 15 driving the push-pull rod 14 to rotate, and a displacement mechanism driving the push-pull rod 14 to move linearly.

[0024] The displacement mechanism includes a pull rod base plate 16, and the push-pull rod 14 is installed through the pull rod base plate 16. The pull rod base plate 16 is provided with a convex strip, and the upper storage rack 4 is provided with a penetrating channel 17. The convex strip slides back and forth with the channel 17. A No. 2 rack 18 is installed on the upper end surface of the convex strip. The No. 2 rack 18 is meshed with a No. 2 gear 19, and the No. 2 gear 19 is driven to rotate by a servo motor 20.

[0025] The output end of the square motor 15 is provided with a first circular gear 22 , and the push-pull rod 14 is provided with a second circular gear 23 , and the first circular gear 22 and the second circular gear 23 are meshed with each other.

[0026] The servo motor 20 is installed on the upper storage rack 4 , and a U-shaped reinforcement plate 24 is installed on the upper end of the upper storage rack 4 .

[0027] Limiting plates 25 are installed at the front and rear of the pull rod bottom plate 16 to limit the displacement distance of the push-pull rod 14 .

[0028] A hook is disposed at the top of the push-pull rod 14 , and the hook comprises a cylindrical chassis 26 and an L-shaped member 27 mounted on the cylindrical chassis 26 , and the two L-shaped members 27 are disposed in opposite directions.

[0029] Because a hexagonal nut is welded on one end of the barrel, a draw hook is used to ensure that the barrel can be pulled out and can also ensure that the barrel can rotate with it. When it is necessary to unhook, the push-pull rod 14 can be reversed, and the operation of pulling the barrel is performed by rotating and limiting the draw hook. The draw hook is cylindrical as a whole, and the cylindrical shape can adapt to the rotation of the nut. The two L-shaped parts 27 can limit the nuts, and the length is slightly larger than the size of the nut. There is a space between the two L-shaped parts 27 to allow the nuts to pass smoothly. The vertical parts of the two L-shaped parts 27 are axial limit baffles, and the function of the axial limit baffle is to fix the nut. At this time, the push-pull rod 14 retracts, and the barrel will be driven by the push-pull rod 14 because of the axial limit baffle. The material selected for the draw hook has high strength and good wear resistance, and the hardness should not be too high to avoid increasing the wear of the barrel.

[0030] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
