[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 、 2 As shown in Figures 3, 4, 5, and 6, the present utility model provides a technical solution: a main housing reaming device, including: a blanking conveyor is provided on one side of the loading conveyor 1, and both the loading conveyor 1 and the blanking conveyor are belt conveyors; the loading and unloading assembly is placed on one side of the loading conveyor 1, and the loading and unloading assembly includes a rotating rod 11. A driving part is provided at the bottom of the rotating rod 11 for driving the rotating rod 11 to lift and rotate. Three fixed sleeves 20 are fixedly connected to the outer side of the top of the rotating rod 11. A sliding clamping plate 6 for fixing the material is provided in the middle of the fixed sleeve 20. An electromagnet 17 for driving the sliding clamping plate 6 to slide is installed on the outer side of the sliding clamping plate 6; the reaming assembly is placed on one side of the loading and unloading assembly, and the reaming assembly includes an expansion sleeve 7. The expansion sleeve 7 is a pipe fitting with expansion joints arranged vertically and staggered. A plurality of extrusion blocks 8 are fixedly connected at equal intervals inside the expansion sleeve 7. An extrusion cone 10 for driving the extrusion block 8 is provided in the middle of the extrusion block 8. A hydraulic cylinder 9 for driving the extrusion cone 10 is provided below the expansion sleeve 7.

[0024] It should be noted that the present utility model is installed with a PLC controller and an operation panel. The cylindrical main housing is placed on the feeding conveyor 1. When the housing is conveyed to the designated position, the rotating rod 11 drives the fixed sleeve 20 to move downward. Here, during this period, the three fixed sleeves 20 move downward simultaneously, corresponding to the feeding conveyor 1, the expansion sleeve 7, and the discharging conveyor in a counterclockwise direction respectively. When the rotating rod 11 drives the extrusion cone 10 to move downward to the limit position, the electromagnet 17 is simultaneously energized, and the sliding clamping plate 6 is driven by the electromagnet 17 to clamp and fix the housing. When the rotating rod 11 rises, the housing is lifted, so that the height of the bottom of the housing is greater than the height of the top of the expansion sleeve 7. At this time, the rotating rod 11 drives the fixed sleeve 20 to rotate, and the positions of the three fixed sleeves 20 are correspondingly switched. The unprocessed one is placed above the expansion sleeve 7, and the processed housing is rotated above the discharging conveyor, and so on in a cycle to complete the automatic loading and unloading operation.

[0025] Please refer to Figure 1 、 2 As shown in the figure, a double-axis cylinder 2 is fixedly connected to one side of the feeding conveyor 1, and a V-shaped fixed groove 4 is fixedly connected to the output end of the double-axis cylinder 2.

[0026] It should be noted that an infrared sensor is installed at the end of the feeding conveyor 1 of the present utility model to monitor the position of the frontmost housing. When the end of the frontmost housing contacts the infrared sensor, the controller controls the feeding conveyor 1 to stop conveying, and controls the double-axis cylinder 2 to extend to fix and extrude the housing through the fixed groove 4.

[0027] Please refer to Figure 3 As shown in the figure, it further includes an equipment rack 5. The driving part includes a lifting seat 13 slidably connected to one side of the equipment rack 5. A cylinder 14 is fixedly connected to the bottom of the lifting seat 13, and the output end of the cylinder 14 is fixedly connected to the top of the feeding conveyor 1. A motor 12 is fixedly connected to the bottom of the lifting seat 13, and the output end of the motor 12 is fixedly connected to the rotating rod 11.

[0028] It should be noted that a guide rail is fixedly connected to one side of the equipment rack 5 of the present utility model. The lifting seat 13 is slidably installed outside the guide rail. The cylinder 14 drives the lifting seat 13 to move on the guide rail through telescoping. The lifting seat 13 drives the rotating rod 11 to lift. At the same time, the motor 12 drives the rotating rod 11 to rotate. Two groups of magnets are installed on the rotating rod 11 corresponding to the positions of the fixed sleeves 20, and a Hall sensor corresponding to the position of the expansion sleeve 7 is fixedly connected to the top of the equipment rack 5. When the rotating rod 11 rises to the limit position and descends to the limit position, the magnets and the Hall sensor are in corresponding positions, so as to realize the adjustment of the angle of the fixed sleeve 20.

[0029] Please refer to Figure 1 、 3As shown in FIGS. 5, three connecting rods 15 are fixedly connected to the outer side of the top of the rotating rod 11 at equal intervals. There are two connecting rods 15 in each group, which are arranged up and down and fixedly connected to the corresponding fixed sleeve 20. A fixing plate 16 is fixedly connected to the middle of the connecting rod 15. A sliding plate 18 is slidably connected to one side of the middle of the connecting rod 15 close to the fixed sleeve 20. Electromagnets 17 are fixedly connected to the corresponding positions of the fixing plate 16 and the sliding plate 18. When the two electromagnets 17 are energized, the magnetic poles are the same. A limiting slide rod 3 is fixedly connected to the middle of the sliding plate 18. The limiting slide rod 3 passes through the fixed sleeve 20 and is fixedly connected to the sliding clamping plate 6. The limiting slide rod 3 is slidably connected to the fixed sleeve 20. A return spring 19 is sleeved on the outer side of the connecting rod 15 and between the sliding plate 18 and the fixed sleeve 20.

[0030] It should be noted that in the present utility model, when the motor 12 drives the rotating rod 11 to rotate to a specified position, the Hall sensor detects a magnetic signal, and the controller controls the motor 12 to stop rotating. And the cylinder 14 drives the lifting seat 13 to move downward, and the lifting seat 13 drives the rotating rod 11 to move downward. At this time, the fixed sleeve 20 is placed outside the housing. When the rotating rod 11 moves downward to the limit position, the electromagnets 17 are simultaneously energized. Under the action of the repulsive force, the sliding plate 18 drives the limiting slide rod 3 to move inward to the fixed sleeve 20. The limiting slide rod 3 squeezes and fixes the housing inside the fixed sleeve 20 through the sliding clamping plate 6. Then, after the rotating rod 11 rises and rotates, the housing is sleeved on the outside of the expansion sleeve 7. The electromagnets 17 are powered off. Under the reset action of the return spring 19, the sliding clamping plate 6 fits against the inner wall of the fixed sleeve 20, and the expansion sleeve 7 performs an operation of expanding the hole of the housing.

[0031] Please refer to Figure 4 、 6 As shown in FIGS., the expansion sleeve 7 is placed on the top of the equipment rack 5. The hydraulic cylinder 9 is fixedly connected to the bottom of the equipment rack 5. The output end of the equipment rack 5 is fixedly connected to the extrusion cone 10.

[0032] It should be noted that when the present utility model expands the hole, the hydraulic cylinder 9 drives the extrusion cone 10 to move downward. The slope of the extrusion cone 10 gradually increases from bottom to top. By extrusion, the extrusion block 8 is exaggerated outward, and the extrusion block 8 drives the expansion sleeve 7 to expand outward. The expansion sleeve 7 can perform an operation of expanding the hole through extrusion.
