The storage mechanism 100 includes a storage hopper 110, and the storage hopper 110 is provided with a storage cavity 111 for placing multiple planetary gear shafts from bottom to top and a discharge port 112 connected to the storage cavity 111; the drilling mechanism 200 is arranged on the side of the storage hopper 110, and is used to drill radial holes for a single planetary gear shaft; the pushing mechanism 300 is used to abut against one end of a single planetary gear shaft in the storage cavity 111, so as to push the single planetary gear shaft to the drilling mechanism 200; the pressing mechanism 400 corresponds to the drilling mechanism 200, and is used to press or loosen the single planetary gear shaft at the drilling mechanism 200.

[0022] When in use, each planetary gear shaft to be drilled is placed in the storage chamber 111 from bottom to top, and the pushing mechanism 300 is manipulated so that the pushing mechanism 300 can abut against one end of a single planetary gear shaft in the storage chamber 111, so that the single planetary gear shaft is pushed to the drilling mechanism 200 to realize the feeding of the planetary gear shaft, and the pressing mechanism 400 is manipulated so that the pressing mechanism 400 can press the single planetary gear shaft at the drilling mechanism 200, and then the drilling mechanism 200 is manipulated so that the drilling mechanism 200 can be pressed. The hole mechanism 200 can drill radial holes on a single planetary axle. After the drilling of the planetary axle is completed, the clamping mechanism 400 can be manipulated to loosen the planetary axle, and the next planetary axle to be drilled will push the planetary axle that has been drilled away from the drilling mechanism 200 to achieve the unloading of the planetary axle. The drilling device is suitable for use in large-scale drilling of planetary axles, and can realize the self-loading and self-unloading process of the planetary axle, reducing the time consumption during loading and unloading, and improving the drilling efficiency of the planetary axle.

[0023] As a preferred embodiment, please refer to Figure 1 The upper and lower surfaces of the storage chamber 111 are both opened, and the lower opening of the storage chamber 111 forms the discharge port 112, so that the planetary axle can be placed from bottom to top into the storage chamber 111 through the feed port, and the planetary axle in the storage chamber 111 is discharged along the discharge port 112 under the action of its own gravity.

[0024] As a preferred embodiment, please refer to Figure 1 The storage chamber 111 has an upper chamber and a lower chamber. The two opposite chamber walls of the upper chamber are inclined structures for placing multiple planetary axles. The distance between the two opposite chamber walls of the lower chamber is equal to the diameter of a single planetary axle to achieve the top-down placement of a single planetary axle.

[0025] As a preferred embodiment, please refer to Figure 1The material storage mechanism 100 also includes a material guide groove 120 horizontally arranged directly below the material storage hopper 110, and the material guide groove 120 has a first end with an opening and a second end with a sealing setting. The notch at the middle position of the material guide groove 120 is connected to the discharge port 112 to receive the planetary gear shaft at the bottom of the material storage cavity 111, and can radially limit the planetary gear shaft to prevent radial deviation of the planetary gear shaft when moving in the material guide groove 120.

[0026] As a preferred embodiment, please refer to Figure 1 The groove width of the guide groove 120 is equal to the diameter of a single planetary gear shaft, so that the radial direction of the planetary gear shaft can be limited by the guide groove 120 to prevent the planetary gear shaft from radially offset when moving in the guide groove 120.

[0027] As a preferred embodiment, please refer to Figure 1 The depth of the guide groove 120 is greater than or equal to the diameter of a single planetary gear axle and less than the diameters of two planetary gear axles, so that only a single planetary gear axle is allowed to enter the guide groove 120 at a time.

[0028] As a preferred embodiment, please refer to Figure 1 and Figure 2The drilling mechanism 200 is arranged at the first end of the guide groove 120, and the drilling mechanism 200 includes two drill bits 210, two first rotating driving members 220 and a moving assembly 230. The two drill bits 210 are horizontally and coaxially arranged on the side of the guide groove 120 along a length direction perpendicular to the guide groove 120. The output ends of the two first rotating driving members 220 are respectively fixedly connected to the corresponding two drill bits 210 for driving the drill bits 210 to rotate. The moving assembly 230 is connected to the two first rotating driving members 220 for driving the two first rotating driving members 220 to move closer to each other or away from each other along a length direction perpendicular to the guide groove 120. By manipulating the moving assembly 230, the moving assembly 230 can drive the two first The rotating driving members 220 are close to each other, and then by controlling the two first rotating driving members 220, the two first rotating driving members 220 can drive the corresponding drill bits 210 to rotate to drill the planetary gear axles. When the drilling is completed, by controlling the moving assembly 230, the moving assembly 230 can drive the two first rotating driving members 220 to move away from each other, so that the two drill bits 210 can be moved out of the planetary gear axles. Due to the large diameter of the planetary gear axles, the existing drilling device uses a longer drill bit 210 in the process of drilling holes on the planetary gear axles, which makes the drilling stroke longer and the parallelism of the drilling is poor, resulting in poor drilling effect on the planetary gear axles. By drilling holes on the planetary gear axles at the same time with two coaxial and horizontally arranged drill bits 210, the parallelism of the drilling can be improved.

[0029] As a preferred embodiment, please refer to Figure 1 A through hole 121 is provided on two opposite side walls of the first end of the material guide groove 120. The two through holes 121 are respectively used for the corresponding drill bits 210 to slide through, so that the two drill bits 210 can enter the material guide groove 120 to drill holes in the planetary gear shaft.

The two moving seats 231 are respectively fixedly connected to the corresponding two first rotating driving members 220. The first rack 232 and the second rack 233 are both arranged along the length direction perpendicular to the guide trough 120.

The gear 234 is rotatably arranged between the first rack 232 and the second rack 233 and is connected to the first The rack 232 and the second rack 233 are both meshed, and the output end of the second rotating drive member 235 is coaxially fixed to the gear 234, and is used to drive the gear 234 to rotate. By manipulating the second rotating drive member 235, the second rotating drive member 235 can drive the gear 234 to rotate forward or reverse. According to the transmission principle of the gear 234 and the rack, the two gears 234 can move in opposite directions, so that the two moving seats 231 can approach each other or move away from each other, and drive the two first rotating drive members 220 to approach each other or move away from each other.

[0031] As a preferred embodiment, please refer to Figure 1 The pushing mechanism 300 is arranged at the second end of the guide groove 120, and the pushing mechanism 300 includes a pushing rod 310 and a first telescopic driving member 320. The pushing rod 310 is slidably arranged in the guide groove 120, and the first telescopic driving member 320 is fixed on the guide groove 120.

When the pushing rod 310 pushes the planetary gear shaft to the first end of the guide groove 120, the pushing rod 310 is also used To block the planetary gear shaft above it from entering the material guide groove 120, to prevent the planetary gear shaft in the storage chamber 111 from entering the material guide groove 120 when the pushing rod 310 pushes the planetary gear shaft to the first end of the material guide groove 120, so that the pushing rod 310 cannot smoothly return to the second end of the material guide groove 120, and to ensure that the pushing rod 310 can push materials next time, by manipulating the first telescopic driving member 320, the first telescopic driving member 320 can drive the pushing rod 310 to move in the material guide groove 120, so that one end of the pushing rod 310 abuts against the end of the planetary gear shaft, and pushes the planetary gear shaft to the drilling mechanism 200.

[0032] As a preferred embodiment, please refer to Figure 1 and Figure 2The clamping mechanism 400 includes a clamping block 410 and a second telescopic driving member 420. The output end of the second telescopic driving member 420 is fixedly connected to the clamping block 410, and is used to drive the clamping block 410 to move up and down, so that the clamping block 410 can clamp or loosen the planetary gear shaft.

[0034] In order to better understand the present invention, the following Figure 1 - Figure 2 The working principle of the technical solution of the utility model is described in detail:

[0035] When in use, the planetary axles to be drilled are placed in the storage chamber 111 from bottom to top. The planetary axles in the storage chamber 111 are discharged along the discharge port 112 under the action of their own gravity and enter the guide groove 120. By manipulating the first telescopic driving member 320, the first telescopic driving member 320 can drive the push rod 310 to move in the guide groove 120, so that one end of the push rod 310 abuts against the end of the planetary axle and pushes the planetary axle to the drilling mechanism 200, so as to realize the loading of the planetary axle. By manipulating the second telescopic driving member 320, the push rod 310 can drive the push rod 310 to move in the guide groove 120, so that one end of the push rod 310 abuts against the end of the planetary axle and pushes the planetary axle to the drilling mechanism 200. The driving member 420 enables the second telescopic driving member 420 to drive the pressing block 410 to move downward, so that the pressing block 410 can press the planetary gear shaft, and by manipulating the second rotating driving member 235, the second rotating driving member 235 can drive the gear 234 to rotate forward. According to the transmission principle of the gear 234 and the rack, the two gears 234 can move in opposite directions, so that the two moving seats 231 can approach each other, and drive the two first rotating driving members 220 to approach each other, and then by manipulating the two first rotating driving members The two first rotating driving members 220 can drive the corresponding drill bits 210 to rotate to drill holes in the planetary gear shaft. When the drilling is completed, the second rotating driving member 235 is controlled so that the second rotating driving member 235 can drive the gear 234 to reverse. According to the transmission principle of the gear 234 and the rack, the two gears 234 can move in opposite directions, so that the two moving seats 231 can move away from each other and drive the two first rotating driving members 220 to move away from each other, so that the two drill bits 210 can move away from the planetary gear shaft. When the planetary axle is drilled, the second telescopic driving member 420 is controlled so that the second telescopic driving member 420 can drive the clamping block 410 to move upward, so that the clamping block 410 can loosen the planetary axle, and the next planetary axle to be drilled will push the planetary axle that has been drilled out from the first end of the guide groove 120 to realize the unloading of the planetary axle. The drilling device is suitable for large-scale drilling of planetary axles, and can realize the self-loading and self-unloading process of the planetary axles, thereby reducing the time consumption in loading and unloading and improving the drilling efficiency of the planetary axles.

[0036] The planetary gear shaft radial drilling device provided by the utility model has the following beneficial effects:

[0037] (1) When the push rod 310 pushes the planetary gear shaft to the first end of the material guide trough 120, the push rod 310 is also used to block the planetary gear shaft above it from entering the material guide trough 120, preventing the planetary gear shaft in the storage chamber 111 from entering the material guide trough 120 when the push rod 310 pushes the planetary gear shaft to the first end of the material guide trough 120, so that the push rod 310 cannot smoothly return to the second end of the material guide trough 120, and ensures that the push rod 310 can push the material next time;

[0038] (2) Since the diameter of the planetary gear shaft is relatively large, the existing drilling device uses a relatively long drill bit 210 in the process of drilling holes on the planetary gear shaft, which results in a relatively long drilling stroke and poor parallelism of the holes, resulting in poor drilling effect on the planetary gear shaft. By drilling holes on the planetary gear shaft simultaneously with two coaxial and horizontally arranged drill bits 210, the parallelism of the holes can be improved;

[0039] (3) The drilling device is suitable for use in large-scale drilling of planetary axles. It can realize the self-loading and self-unloading process of the planetary axles, reduce the time consumption during loading and unloading, and improve the drilling efficiency of the planetary axles.

[0040] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
