DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0031] See also Figures 1 to 12In an embodiment of the present invention, a hole-making device for ear processing includes a first ear feeding mechanism 100 and a second ear feeding mechanism 300 which are symmetrically arranged on a base 400, and a hole-making mechanism 200 is provided between the first ear feeding mechanism 100 and the second ear feeding mechanism 300; the first ear feeding mechanism 100 and the second ear feeding mechanism 300 are composed of the same structure.

[0032] By adopting the above technical solution, when in use, the first ear feeding mechanism 100 and the second ear feeding mechanism 300 arrange and place a plurality of ear plates, and then transport them to the hole opening mechanism 200 for hole opening processing. The first ear feeding mechanism 100 and the second ear feeding mechanism 300 work alternately, which can realize non-stop operation of the equipment and reduce manual labor intensity, thereby greatly improving the processing efficiency of the ear plates.

[0033] Specifically, the first lifting ear feeding mechanism 100 includes a feeding cylinder 1 fixed to the base 400, the cylinder rod of the feeding cylinder 1 is fixed to the carrier 2, the bottom of the carrier 2 is provided with two slides, and is slidably connected to the slide rail 9; the carrier 2 is matched with the cardboard 4; the two ends of the cardboard 4 are fixed to the base 400 through the Z-shaped frame 13; the cardboard 4 is also fixed with a guide rail 7; the guide rail 7 is slidably connected with the loading and unloading assembly 8. The carrier 2 is provided with a plurality of lifting ear slots 3, and a through hole with a diameter larger than the diameter of the drill bit 27 is provided in the middle of each lifting ear slot 3; An opening slot 5 is formed at one end of the clamping plate 4, and a discharge slot 6 is formed at the other end.

[0034] By adopting the above technical solution, when working, the loading and unloading components 8 arrange the ear plates one by one in the ear grooves 3 on the carrier 2, and then the cylinder rod of the feeding cylinder 1 is extended to push the carrier 2 to slide along the slide rail 9 toward the bottom side of the hole opening mechanism 200, so that the hole opening mechanism 200 can perform hole opening operation on the ear plates.

[0035] Please refer to the attached Figures 3 to 5 In this embodiment, the hole-opening mechanism 200 includes two end brackets 21, and a frame body 22 is fixed on the top of the two end brackets 21; a plurality of hole-opening motors 26 are arranged inside the frame body 22, and a drill bit 27 is mounted on the output shaft of each hole-opening motor 26.

[0036] By adopting the above technical solution, a hole-making motor 26 and a drill bit 27 are provided above each ear plate. When the ear plate is transported to the bottom of the drill bit 27, the hole-making motor 26 drives the drill bit 27 to make holes in the ear plate. This batch processing method effectively reduces the working time and greatly improves the processing efficiency of the ear plate.

[0037] Please refer to the attached Fig.10 In this embodiment, a nut seat is fixed on the outer side of the upper end of the loading and unloading assembly 8, and the nut seat is connected with the screw rod 10; both ends of the screw rod 10 are fixed on the gantry 12 through seat bearings, and the screw rod 10 is also connected with the motor 11 through a coupling; the gantry 12 is fixed on the base 400.

[0038] To be more specific, the loading and unloading assembly 8 includes a guide seat 82 slidably connected to the guide rail 7, and the guide seat 82 is fixed on one side of the ear material box 81; a detection assembly 87 is provided on the side of the ear material box 81 close to the opening groove 5, and a material picking mechanism is fixed on the side of the ear material box 81 close to the discharge groove 6.

[0039] By adopting the above technical solution, the motor 11 drives the screw rod 10 to rotate, and the nut seat converts the rotational motion of the screw rod 10 into linear motion, so that the ear box 81 slides laterally along the guide rail 7 through the guide seat 82 on one side, so that the ear plate stored in the ear box 81 will fall when it slides above the ear slot 3, thereby realizing the one-by-one loading of the ear plates.

[0040] Please see attached Figure 7 and Fig.10 In this embodiment, the material taking mechanism includes a side fixing frame 83 fixed to the lifting ear material box 81, and a material receiving cylinder 84 is installed on the side fixing frame 83; an electromagnet 86 is fixed to the cylinder rod end of the material receiving cylinder 84; and the electromagnet 86 is also fixedly connected to the lifting frame 85.

[0041] By adopting the above technical solution, when placing the ear plate, the loading and unloading assembly 8 slides from left to right. If there is a processed ear on the carrier 2, the electromagnet 86 is energized. Since the electromagnet 86 is fixed to the lifting frame 85, the adsorption area of ​​the ear can be increased, thereby improving the stability of the ear. As the loading and unloading assembly 8 moves from left to right, the cylinder rod of the receiving cylinder 84 gradually contracts, and the multiple lifting ears are adsorbed one by one; it should be noted that during this process, the current of the electromagnet 86 gradually increases, increasing the magnetic force of the electromagnet 86, thereby ensuring that all the lifting ears can be taken out; During the sliding process of the loading and unloading assembly 8, the ear plate will fall into the empty lifting ear slot 3, thereby achieving the effect of taking materials and releasing materials at the same time; and this process does not require any human intervention, which effectively improves the degree of automation of the equipment.

[0042] After all the processed lifting ears are picked up and the ear plates are placed in the lifting ear slots 3, the collecting cylinder 84 just moves to the top of the discharge slot 6, and the cylinder rod of the collecting cylinder 84 extends, so that the stacked lifting ears are placed on the discharge slot 6, and the power supply of the electromagnet 86 is disconnected, which makes it convenient for the staff to pick up the items.

[0043] Please refer to the attached Figure 8 , Figure 11 to Figure 12 In this embodiment, the detection assembly 87 includes a movable mounting seat 871, and two first swing arms 872 are movably connected to the inner side of the movable mounting seat 871, and the inner sides of the two first swing arms 872 are movably connected to the second swing arms 873 through a rotating shaft; the lower end of the second swing arm 873 is connected to a roller 874 through a rotating shaft; A shaft pressure sensor is also provided between the roller 874 and the rotating shaft; the first swing arm 872 and the second swing arm 873 are also connected via a tension spring 875.

[0044] To be more specific, a rectangular notch is provided in the middle of the lower end of one side of the movable mounting seat 871 on which the ear material box 81 is mounted, and the width of the rectangular notch is greater than the distance between the two second swing arms 873 .

[0045] By adopting the above technical solution, when the ear box 81 moves from left to right along the guide rail 7 through the guide seat 82, under the action of the tension spring 875, the first swing arm 872 and the second swing arm 873 are in the same straight line, and the roller 874 rolls forward along the upper surface of the carrier 2; after the ear plate is placed in the ear slot 3, the ear box 81 moves from right to left (it should be noted that the depth of the ear slot 3 is the thickness of the ear plate, so that after the ear plate is placed in the ear slot, its upper surface is flush; therefore, the ear box 81 can slide along the carrier 2 equipped with the ear plate); when the roller 874 slides to the opening slot 5, since the movable mounting seat 871 and the first swing arm 872 are movably connected through the rotating shaft, and the roller 874 will fall into the open slot 5 under its own weight. At this time, the ear box 81 continues to move to the left, and then the first swing arm 872 will be parallel to the outer wall of the ear box 81. Under the obstruction of the outer edge of the open slot 5, the second swing arm 873 will fold inward and be parallel to the carrier 2; in this way, the roller 874 will be connected with the ear plate in the ear box 81. Under the weight of the ear plate itself, a downward force will be applied to the roller 874. Since an axle weight sensor is provided inside the roller 874, the weight can be sensed; if there is weight, it proves that there are unprocessed ear plates inside; if there is no pressure, the ear plates have been used up, and then the axle weight sensor transmits the signal to the external sound and light alarm so that the staff can replenish the ear plates in time.

[0046] Please refer to the attached Figures 3 to 6 In this embodiment, a sliding frame 28 is installed on one side of the plurality of hole-opening motors 26, and the plurality of sliding frames 28 are slidably connected to a fixed slide 29; the fixed slide 29 is fixed to the frame body 22; The plurality of opening motors 26 are also fixed to the lifting frame 25 ; a lifting cylinder 24 is installed at both ends of the lifting frame 25 ; the two lifting cylinders 24 are fixed at both ends of the cylinder bracket 23 , and the cylinder bracket 23 is fixed on the frame body 22 .

[0047] By adopting the above technical solution, when drilling a hole in the ear plate, the extension and retraction of the lifting cylinder 24 can drive the lifting and lowering of the lifting frame 25 equipped with the hole drilling motor 26, thereby facilitating the adjustment and movement of the drill bit 27 in the hole depth direction; in addition, the setting of the sliding frame 28 and the fixed slide 29 improves the stability when multiple hole drilling motors 26 move at the same time.

[0048] The working principle is as follows: the motor 11 drives the screw rod 10 to rotate, and the nut seat converts the rotational motion of the screw rod 10 into a linear motion, so that the ear box 81 slides horizontally along the guide rail 7 through the guide seat 82 on one side, so that the ear plate stored in the ear box 81 will fall when it slides to the top of the ear slot 3, thereby realizing the one-by-one loading of the ear plates; when placing the ear plate, the loading and unloading assembly 8 slides from left to right. If there is a processed ear on the carrier 2, the electromagnet 86 is energized. Since the electromagnet 86 is fixed to the lifting frame 85, the adsorption area of ​​the ear can be increased, and the stability of the ear can be improved; As the loading and unloading assembly 8 moves from left to right, the cylinder rod of the receiving cylinder 84 gradually contracts, and the multiple lifting ears are adsorbed one by one; it should be noted that during this process, the current of the electromagnet 86 gradually increases, increasing the magnetic force of the electromagnet 86, thereby ensuring that all the lifting ears can be taken out; During the sliding process of the loading and unloading assembly 8, the ear plate will fall into the empty lifting ear slot 3, thereby achieving the effect of taking materials and releasing materials at the same time; and this process does not require any human intervention, which effectively improves the degree of automation of the equipment.

[0049] After all the processed lifting ears are picked up and the ear plates are placed in the lifting ear slots 3, the receiving cylinder 84 is just moved to the top of the discharge slot 6, and the cylinder rod of the receiving cylinder 84 is extended, so that the stacked lifting ears are placed on the discharge slot 6, and the power supply of the electromagnet 86 is disconnected, which makes it convenient for the staff to pick up the parts; When the ear box 81 moves from left to right along the guide rail 7 through the guide seat 82, under the action of the tension spring 875, the first swing arm 872 and the second swing arm 873 are in the same straight line, and the roller 874 rolls forward along the upper surface of the carrier 2; after the ear plate is placed in the ear slot 3, the ear box 81 moves from right to left (it should be noted that the depth of the ear slot 3 is the thickness of the ear plate, so that after the ear plate is placed in the ear slot, its upper surface is flush; therefore, the ear box 81 can slide along the carrier 2 equipped with the ear plate); when the roller 874 slides to the opening slot 5, since the movable mounting seat 871 and the first swing arm 872 are movably connected through the rotating shaft, and the roller 874 is automatically The heavy object will fall into the open slot 5. At this time, the ear box 81 will continue to move to the left, and then the first swing arm 872 will be parallel to the outer wall of the ear box 81. Under the obstruction of the outer edge of the open slot 5, the second swing arm 873 will fold inward and be parallel to the carrier 2; in this way, the roller 874 will be connected with the ear plate in the ear box 81. Under the weight of the ear plate itself, a downward force will be applied to the roller 874. Since an axle weight sensor is provided inside the roller 874, the weight can be sensed; if there is weight, it proves that there are unprocessed ear plates inside; if there is no pressure, the ear plates have been used up, and then the axle weight sensor transmits the signal to the external sound and light alarm so that the staff can replenish the ear plates in time.
