[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a double-headed chamfering machine for pipe fittings, comprising: a pipe fitting placement frame, the pipe fitting placement frame including multiple inclined support frames 1 and a support beam 3 welded to the top of the inclined support frame 1; a receiving beam 2 installed at the end of the inclined support frame 1 by bolts, and the end of the receiving beam 2 being higher than the end of the inclined support frame 1; a material taking component placed at the connection between the inclined support frame 1 and the receiving beam 2, the material taking component including a pusher plate 10 that is lifted and positioned at the end of the inclined support frame 1, the top of the inclined support frame 1 having a material taking groove for lifting the pipe fitting, a pusher plate 2 11 that is lifted and positioned inside the pusher plate 10, the top of the pusher plate 2 11 having an inclined structure for pushing the pipe fitting onto the receiving beam 2; and a chamfering mechanism placed on both sides of the inclined support frame 1, the chamfering mechanism including a support side plate 15 that is movably disposed on one side of the inclined support frame 1 and a chamfering blade 7, the end of the support side plate 15 having a positioning and fixing part for positioning and fixing the lifted pipe fitting.

[0026] It should be noted that this utility model is equipped with a corresponding operation panel. The support beam 3 at the top of the inclined support frame 1 is inclined downward. Under the action of gravity, the pipes are arranged on the top of the support beam 3. The receiving beam 2 blocks the pipes from one end. The pusher plate 10 rises and lifts the steel pipe through the material picking groove at its top, so that the pipe at the front end is lifted. The positioning and fixing part pushes the pipe towards the middle and then squeezes it on one side of the receiving beam 2 through the fixing slot 17. Then the motor 6 drives the chamfering knife 7 to contact the end of the pipe. Under the rotation of the chamfering knife 7, the pipe is chamfered. After the chamfering is completed, the fixing slot 17 and the chamfering knife 7 are reset. The pusher plate 2 11 rises. Under the inclined structure at the top of the pusher plate 2 11, the pipe moves towards the top of the receiving beam 2.

[0027] Please see Figure 3 , 4 As shown, a through groove is provided on one side of the pusher plate 10, and a limit shaft is slidably connected in the through groove. The limit shaft is fixedly connected to the inclined support frame 1. A lifting cylinder 12 is fixedly connected to one side of the bottom of the pusher plate 10, and the output end of the lifting cylinder 12 is fixedly connected to the bottom of the inclined support frame 1.

[0028] It should be noted that the fixed end of the lifting cylinder 12 of this utility model is fixedly connected to the pusher plate 10, and the output end of the lifting cylinder 12 is fixedly connected to the bottom of the inclined support frame 1. When the lifting cylinder 12 extends, under the reaction of the force, the lifting cylinder 12 drives the pusher plate 10 to move upward along the limiting axis, and the top of the pusher plate 10 pushes the tube to the processing position.

[0029] Please see Figure 3 , 4 As shown, a limiting groove 14 is provided on one side of the pusher plate 10, and the pusher plate 11 is slidably connected to the limiting groove 14 through a slider. A lifting cylinder 13 is fixedly connected to the outer side of the pusher plate 10, and the output end of the lifting cylinder 13 is fixedly connected to the slider.

[0030] It should be noted that after the chamfering of both ends is completed, the lifting cylinder 2 13 drives the slider to move upward in the limiting groove 14. The slider drives the pusher plate 2 11 to move upward inside the pusher plate 10. Under the action of the inclined surface of the pusher plate 2 11, the bottom of the pipe is raised above the top of the pusher plate 10. Under the action of gravity, the pipe rolls towards the top of the receiving beam 2.

[0031] Please see Figure 4 , 5As shown in Figure 6, the material handling assembly also includes a support base 9 fixedly connected to one side of the inclined support frame 1. A support frame 4 is fixedly connected to the top of the support base 9. A movable seat 8 is slidably connected to the top of the support frame 4. The movable seat 8 is slidably installed on the top of the support frame 4. A push cylinder 5 for driving the movable seat 8 to move is fixedly connected to one side of the support frame 4. A motor 6 is fixedly connected to the top of the movable seat 8. The output end of the motor 6 is fixedly connected to the chamfering blade 7.

[0032] It should be noted that, after the pipe fitting is clamped and fixed, the push cylinder 5 drives the moving seat 8 to move to one end, the moving seat 8 drives the motor 6 to move to one end, and the motor 6 drives the chamfering cutter 7 to contact the fixed pipe fitting. The chamfering cutter 7 is a disc with an inclined blade. The motor 6 drives the chamfering cutter 7 to rotate, so that the chamfering cutter 7 performs chamfering processing on the end of the pipe fitting.

[0033] Please see Figure 4 , 5 As shown in Figure 6, the positioning and fixing part includes a support plate 20 fixedly attached to one side of the inclined support frame 1. A push cylinder 21 is fixedly attached to one side of the support plate 20. A support side plate 15 is fixedly connected to the output end of the push cylinder 21. A push cylinder 16 is fixedly attached to one side of the support side plate 15. A sliding frame 18 is fixedly connected to the output end of the push cylinder 16. A push cylinder 19 is fixedly attached to the middle of the sliding frame 18. A fixing slot 17 is fixedly connected to the output end of the push cylinder 19.

[0034] It should be noted that when the lifting cylinder 12 extends and pushes the pusher plate 10 to lift the pipe, the push cylinder 21 drives the support side plate 15 to move to one end. A limiting rod is fixedly connected to one side of the support side plate 15 and slidably connected to the support plate 20 to ensure the horizontal and stable movement of the support side plate 15. When the support side plate 15 is in operation, the side of the fixing slot 17 contacts the end of the pipe and pushes the pipe towards the middle position. A pressure sensor is provided on the side of the fixing slot 17. When the pressure between the support side plate 15 and the pipe reaches a preset value, the sensor transmits a signal to the controller. The controller controls the push cylinder 19 to drive the fixing slot 17 to move backward. The extension is paused by the push cylinder 21. Then, the push cylinder 21 continues to extend and moves the fixing slot 17 to the outside of the pipe. The push cylinder 16 extends and moves the sliding frame 18. The sliding frame 18 drives the fixing slot 17 to be locked on the outside of the pipe, thereby squeezing and fixing the pipe.
