Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to a pipeline end chamfering device. Background Art

[0002] Automobile air conditioning systems require various devices, such as condensers, evaporators, and heaters. These devices all require pipes, typically made of aluminum tubes. During processing, the aluminum tubes are first cut to the required length, and then subsequently processed. Chamfering the ends of the pipes after cutting is a necessary step. Chamfering plays a vital role in pipe engineering, not only improving the appearance of the pipes but, more importantly, enhancing their performance and safety. When batch chamfering pipes, automatic loading and unloading mechanisms can improve chamfering efficiency and automate pipe chamfering. Existing loading and unloading mechanisms operate independently, with the unloading mechanism first removing the chamfered pipe, and the loading mechanism then delivering the next pipe. Both mechanisms perform one action each to complete the loading and unloading process, and a certain time interval is required between unloading and loading. Utility Model Content

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0028] Please refer to Figure 1-10 A pipe end chamfering device includes a feeding mechanism 1, a guiding mechanism 2, a pushing mechanism 3, a supporting mechanism 4, and a chamfering mechanism 5. A round pipe 6 that has been cut and to be chamfered is placed in the feeding mechanism 1. The feeding mechanism 1 sequentially transports the round pipe 6 to the guiding mechanism 2, and the guiding mechanism 2 sequentially transports the round pipe 6 to the top of the pushing mechanism 3. The pushing mechanism 3 pushes the round pipe 6 to the supporting mechanism 4. The supporting mechanism 4 and the pushing mechanism 3 jointly position the round pipe 6. The chamfering mechanism 5 chamfers the positioned round pipe 6. After the chamfering of the round pipe 6 is completed, the pushing mechanism 3 returns to its initial position. The chamfered round pipe 6 falls into a collection basket placed at the bottom when the pushing mechanism 3 returns.

[0029] Specifically, the feeding mechanism 1 includes a raw material table 11, a cylinder 12, a top plate 13, a movable plate 14 and a support seat 15. A support plate 111 is set in the raw material table 11, and the support plate 111 is tilted. One end of the support plate 111 is provided with a movable groove. The top plate 13 is movably set in the movable groove. The multiple round tubes 6 to be chamfered are placed on the support plate 111. The support seat 15 is set at the bottom of the raw material table 11 and below the movable groove. The cylinder 12 is set at the top of the support seat 15. The top plate 13 is set at the bottom of the raw material table 11. At the output end of the cylinder 12, due to the inclined setting of 111, part of the round tube 6 moves to the top of the movable groove and is supported by the top plate 13. The top plate 13 is fixedly connected to the movable plate 14. The lower end of the support plate is provided with a movable hole. The movable plate is movably set in the movable hole. When the top plate 13 moves upward, in order to prevent the round tube 6 from sliding to the bottom of the top plate 13, the movable plate 14 is vertically set. One side of the movable plate 14 is slidably connected to the lower side of the support plate 111, and the lower part of the movable plate 14 is slidably set on the support seat 15.

[0030] In order to deliver the round tube 6 to the guide mechanism 2, the top plate 13 includes a horizontal portion 131 and a circular arc portion 132. The outer diameter of the round tube 6 is equal to the inner diameter of the circular arc portion 132. Cylinder 12 drives the top plate 13 to deliver the round tube 6 from the lower end of the support plate 111 to the top of the raw material platform 11. After the round tube 6 slides from the top plate 13 to the guide mechanism 2, the top plate 13 retreats to the lower end of the support plate 111, and the movable plate 14 also moves down to the lower end of the support plate 111 along with the top plate 13. The round tube 6, which is blocked by the movable plate 14 at the lower end of the support plate 111, slides onto the top plate 13 under the action of gravity and inertia. The top plate 13 repeatedly moves back and forth between the bottom end of the support plate 111 and the top end of the raw material platform 11 to complete the sequential delivery of multiple round tubes 6.

[0031] In order to send the round tube 6 to the top of the pushing mechanism 3, the guiding mechanism 2 includes an inclined portion 21 and a vertical portion 22. The higher side of the inclined portion 21 is connected to the top of one side of the raw material platform 11. The cylinder 12 sends the top plate 13 and the round tube 6 at its top to the upper end of the inclined portion 21. The top end of the vertical portion 22 is connected to the lower side of the inclined portion 21. The bottom end of the vertical portion 22 is located above the pushing mechanism 3.

[0032] In order to push the round tube 6 in the vertical portion 22 to the chamfered position, the pushing mechanism 3 includes a motor 1 31, a rotating rod 32, a connecting rod 1 33, a connecting rod 2 34, and a pushing block 35. The rotating rod 32 is arranged at the output end of the motor 1 31, one end of the connecting rod 1 33 is fixedly connected to the rotating rod 32, the other end of the connecting rod 1 33 is rotatably connected to the connecting rod 2 34, and the end of the connecting rod 2 34 away from the connecting rod 1 33 is rotatably connected to the pushing block 35. The pushing block 35 is horizontally slidably arranged below the guide mechanism 2, and its initial position is located at the bottom end of the vertical portion 22. The motor 1 31 drives the rotating rod 32 to rotate back and forth 90 degrees repeatedly. The rotation of the rotating rod 32 drives one end of the connecting rod 1 33 to rotate 90 degrees. The rotating end of the connecting rod 1 33 drives the connecting rod 2 34 to move. The connecting rod 2 34 drives the pushing block 35 to slide back and forth in the horizontal direction. The pushing block 35 pushes the round tube 6 to the chamfered position in sequence.

[0033] In order to facilitate the sequential pushing of the round tubes 6 , a semicircular groove 351 is provided at a corner of the top of the pushing block 35 . When the pushing block 35 is located at the lower end of the vertical portion 22 , the round tube 6 at the lower end of the vertical portion 22 just falls into the semicircular groove 351 .

[0034] In order to achieve the positioning of the circular tube 6, the supporting mechanism 4 includes a fixed block 41 and a sliding block 42. A semicircular groove 2 411 is provided on the side of the fixed block 41 opposite to the pushing block 35. The semicircular groove 2 411 and the semicircular groove 1 351 position the circular tube 6.

[0035] To prevent the round tube 6 from falling when pushed to the chamfer, the sliding block 42 is slidably disposed on the outer side of the fixed block 41. The side of the sliding block 42 away from the round tube 6 is slidably connected to the fixed block 41, and the other side is provided with a first protrusion 421 and a second protrusion 422. The first protrusion 421 is disposed opposite the first semicircular groove 351, and the pushing block 35 is provided with a third protrusion 352 below the first semicircular groove 351. The first protrusion 421 holds the round tube 6 against the first semicircular groove 351, maintaining the stable movement of the round tube 6 when the pushing mechanism 3 moves toward the chamfer.

[0036] To facilitate the collection of chamfered round tubes 6, the pusher block 35 has a magnet 1 353 on its side near the third protrusion 352. Both the first protrusion 421 and the second protrusion 422 have magnet 2 423 on their sides. The opposing sides of magnet 1 353 and magnet 2 423 have opposite magnetic properties. It should be noted that the pipes in this application are used in condensers, evaporators, and the like within automotive systems and are made of aluminum. When the pusher block 35 moves toward the chamfer, the relative positions of the protrusion 1 421 and the protrusion 3 352 remain unchanged. When the pusher block 35 retreats from the chamfer to the bottom of the guide mechanism 2, the protrusion 352 retreats quickly with the pusher block 35. Due to the magnetic opposites between the magnet 1 353 and the magnet 2 423, the protrusion 1 421 will drive the sliding block 42 to move closer to the pusher block 35. The pusher block 35 retreats earlier than the sliding block 42. The distance between the protrusion 352 and the protrusion 1 421 will first increase and then decrease. 2 and the convex block 421 is at its maximum, the chamfered round tube 6 will fall freely under the action of gravity to realize the unloading action; and when the pushing block 35 retreats to the bottom of the vertical portion 22, the round tube 6 to be chamfered at the bottom of the vertical portion 22 just falls into the semicircular groove 351. At this time, the distance between the convex block 352 and the convex block 421 is reduced, and the next round tube 6 to be chamfered is held between the convex block 421 and the semicircular groove 351, realizing a seamless connection of automatic loading and unloading of the round tube 6, with a simple structure and high efficiency.

[0037] In order to chamfer the circular tube 6, the chamfering mechanism 5 includes a chamfering head, a second motor 51, and a second cylinder 52. The chamfering head is arranged at the output end of the second motor 51, and the second motor 51 is arranged at the output end of the second cylinder 52. A support platform 53 is arranged at the bottom end of the chamfering mechanism 5, and the second cylinder 52 is arranged on the support platform 53. The second motor 51 is slidably arranged on the support platform 53. When the circular tube 6 is fixed to the side of the chamfering mechanism 5 close to the chamfering head by the pushing mechanism 3 and the supporting mechanism 4, the second cylinder 52 drives the second motor 51 to drive the chamfering head to move to the end of the circular tube 6. The second motor 51 is started to drive the chamfering head to chamfer the circular tube 6. After the chamfering is completed, the second cylinder 52 drives the second motor 51 to drive the chamfering head away from the end of the circular tube 6. After the next circular tube 6 moves into place, the above-mentioned action is repeated, and the chamfering of multiple circular tubes 6 can be completed quickly.
