Description

Technical Field

[0001] This utility model relates to the field of electric drill technology, and more specifically, to a dual-axis synchronous drive electric drill. Background Technology

[0002] With the rapid development of the construction and manufacturing industries, electric drills, as an indispensable tool, play a crucial role in various application scenarios. Whether it's drilling holes in reinforced concrete on construction sites or precision machining in manufacturing, electric drills are indispensable tools.

[0003] However, while traditional single-axis electric drills can meet basic drilling needs, they have limitations in efficiency, accuracy, and operational flexibility. Especially when dealing with large-diameter or high-hardness materials, a single motor drive often struggles to provide sufficient torque and stability, thus affecting work efficiency and product quality. For example, on construction sites, when drilling into reinforced concrete, a traditional single-axis electric drill may fail to penetrate the material effectively due to insufficient torque, resulting in slow progress. Similarly, in manufacturing, when precision machining of high-hardness metals is required, a single-motor drive drill may suffer from insufficient stability, leading to decreased drilling accuracy and affecting the quality of the finished product.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

A fixed plate is fixedly connected inside the drill body, and the drive shaft is connected to the fixed plate through a bearing.

[0009] Furthermore, the PLC controller is located inside the handle, which is fixed to the bottom of the drill body.

[0010] Furthermore, in order to adjust the speed and torque of the servo motor, the servo motor is electrically connected to the servo driver, an encoder is installed on the output shaft of the servo motor, and the servo driver is electrically connected to the PLC controller.

[0011] Furthermore, the servo driver is located inside the drill body.

[0012] Furthermore, to enhance the heat dissipation capacity of the electric drill, a heat dissipation cover is connected to the rear end of the drill body. A cooling fan is connected inside the heat dissipation cover, and a heat dissipation vent is provided on the heat dissipation cover. The cooling fan is electrically connected to the PLC controller.

[0013] Furthermore, buttons are provided on the handle.

[0014] Furthermore, a battery compartment is located at the bottom of the handle, and a battery is installed inside the battery compartment.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) By setting two servo motors symmetrically distributed on both sides of the spindle and using helical gear transmission, smooth power transmission and efficient conversion are achieved.

[0026] According to an embodiment of the present invention, a dual-axis synchronous drive electric drill is provided.

[0027] Example 1

[0028] like Figures 1-4As shown, the dual-axis synchronous drive electric drill according to an embodiment of this utility model includes a drill body 1, a drill chuck 2 at one end of the drill body 1, one side of the drill chuck 2 being connected to a spindle 3, and the spindle 3 being connected to the drill body 1 via bearings. The spindle 3 is located inside the drill body 1, and a first helical gear 4 is provided on the spindle 3. Second helical gears 5 are meshed on both sides of the first helical gear 4, and a drive shaft 6 is fixedly connected to the second helical gear 5. One end of the drive shaft 6 is connected to the output shaft of a servo motor 7. The two servo motors 7 are symmetrically distributed on both sides of the spindle 3. This layout can balance the center of gravity of the electric drill, reduce vibration and shaking during operation, thereby improving the overall operational stability. The servo motor 7 is located inside the drill body 1. It is connected to the drill body 1 via a mounting plate 8. A temperature sensor 9 is mounted on the mounting plate 8 to measure the temperature around the motor in real time. The temperature sensor 9 is electrically connected to the PLC controller 10. A fixing plate 11 is fixedly connected inside the drill body 1. The drive shaft 6 is connected to the fixing plate 11 via a bearing. The PLC controller 10 is located inside the handle 12, which is fixed below the drill body 1. The servo motor 7 is electrically connected to the servo driver 13. An encoder is mounted on the output shaft of the servo motor 7. The servo driver 13 is electrically connected to the PLC controller 10 and is located inside the drill body 1. With this design, when the drill bit needs to rotate, the two servo motors 7 are activated to rotate the second helical gears 5 on both sides. The rotation of the second helical gears 5 drives the first helical gear 4 to rotate, thereby driving the spindle 3 and the drill bit to rotate, achieving smooth power transmission and efficient conversion. This design not only significantly improves the output torque and operational stability of the electric drill, but also ensures high efficiency under various complex working conditions. During the operation of the servo motor 7, the encoder can monitor the motor's position and speed in real time, providing high-precision feedback signals. The PLC controller 10 adjusts the operating status of the two servo motors 7 in real time based on these feedback signals. The PLC controller 10 can send instructions to the servo driver 13, which can precisely control the speed and torque of the servo motor 7 according to the instructions of the PLC controller 10, ensuring that the electric drill maintains a high-efficiency and stable working state under various working conditions and that they always remain synchronized.

[0029] like Figures 1-4As shown, a heat dissipation cover 14 is connected to the rear end of the drill body 1. A cooling fan 15 is connected inside the heat dissipation cover 14, and a heat dissipation vent 16 is provided on the heat dissipation cover 14. The cooling fan 15 is electrically connected to the PLC controller 10. The drill body 1 has heat dissipation holes for heat dissipation under low load. A button 17 is provided on the handle 12 for starting the servo motor 7 to rotate. A battery box 18 is provided at the bottom of the handle 12, and a battery is provided inside the battery box 18 for powering the electrical components inside the drill. Through the above scheme, heat dissipation is achieved through the heat dissipation holes under low load. When the temperature measured by the temperature sensor 9 exceeds a predetermined value, the PLC controller 10 will control the cooling fan 15 to start, accelerating the heat dissipation process and ensuring that the drill maintains good temperature control under various working conditions, thereby extending the service life of the drill and improving work efficiency.

[0030] In summary, by utilizing the above-mentioned technical solution of this utility model, in actual use, by setting two servo motors 7 symmetrically distributed on both sides of the spindle 3 and using helical gear transmission, smooth power transmission and efficient conversion are achieved. This design can significantly improve the output torque and operational stability of the electric drill, ensuring that the electric drill can maintain a high-efficiency working state under various complex working conditions. Furthermore, by combining an encoder and a PLC controller 10, it is ensured that the two servo motors 7 can operate precisely and synchronously, improving work efficiency and product quality. In addition, the temperature sensor 9 on the mounting plate 8 can monitor the temperature changes around the servo motors 7 in real time and feed the data back to the PLC controller 10, which can promptly detect overheating and prevent the motors from being damaged due to overheating. Moreover, by setting a cooling fan 15, the heat dissipation effect of the electric drill can be enhanced.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
