The drilling and tapping mechanism includes a drilling and tapping motor, a drill bit, and a tap. The output shaft of the drilling and tapping motor is connected to the input shaft of the transmission device through an elastic coupling.

The driving gear is installed on the output shaft of the drilling and tapping motor, and the driven gear is installed on a transmission shaft parallel to the installation shaft of the drill bit and tap, and is connected to the installation shaft of the drill bit and tap through a synchronous belt.

[0017] In this embodiment, an electromagnetic clutch is installed on the drive shaft. By controlling the engagement and disengagement of the electromagnetic clutch, the drilling and tapping functions can be switched quickly.

The CNC system also features fault diagnosis, alarm prompts, and machining data recording and query functions, facilitating operator monitoring and management of the equipment's operating status.

[0021] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0022] Example: A CNC crawling drilling and tapping machine for fixing holes on long guide rails includes a base 1, a crawling mechanism 6, a drilling and tapping mechanism, and a CNC system.

[0023] The base 1 supports the entire device and is made of high-strength cast iron in one piece, providing excellent stability and resistance to deformation. The base 1 has four height-adjustable support feet, each consisting of a screw and a base with an anti-slip rubber pad. The screw is threaded into pre-drilled holes on the bottom of the base 1, allowing the height of the support feet to be adjusted by rotating the screws. This adapts to different work surfaces with varying flatness and height requirements, ensuring the device remains level and stable during operation.

[0024] The crawling mechanism 6 is mounted on the base and includes a crawling track and a crawling drive device. The crawling track is a high-precision linear guide rail made of high-quality alloy steel, hardened and precision ground, possessing high hardness, low friction coefficient, and good wear resistance. The crawling track runs along the length of the long guide rail and is tightly fixed to the mounting base on the base with bolts to ensure installation accuracy. The crawling drive device consists of a servo motor, a reducer, a ball screw, and a slider. The servo motor is directly connected to the reducer, and the reducer's output shaft is rigidly connected to one end of the ball screw via a coupling. The ball screw is mounted on one side of the crawling track and fixed to the base by bearing seats at both ends. The slider is connected to the mounting plate of the drilling and tapping mechanism and is integrally fixed to the nut on the ball screw. When the servo motor operates, the reducer reduces speed and increases torque, driving the ball screw to rotate, thereby driving the slider and the connected drilling and tapping mechanism to move smoothly on the crawling track, achieving precise machining of different positions on the long guide rail.

[0025] The drilling and tapping mechanism, mounted on the slider of the crawler mechanism, includes a drilling and tapping motor, a drill bit, and a tap. The drilling and tapping motor is a high-performance AC servo motor, characterized by fast response and high speed accuracy. The output shaft of the drilling and tapping motor is connected to the input shaft of the transmission device via a flexible coupling. The transmission device employs a gear transmission structure, including a driving gear and a driven gear. The driving gear is mounted on the output shaft of the drilling and tapping motor, and the driven gear is mounted on a transmission shaft parallel to the mounting shafts of the drill bit and tap, and connected to these shafts via a synchronous belt. An electromagnetic clutch is also mounted on the transmission shaft; by controlling the engagement and disengagement of the electromagnetic clutch, rapid switching between drilling and tapping functions can be achieved. The drill bit and tap are each mounted on their respective mounting shafts, which are installed within the housing of the drilling and tapping mechanism via high-precision bearings. The housing is bolted to the slider of the crawler mechanism, ensuring the stability of the drilling and tapping mechanism during operation.

[0026] The CNC system uses an industrial-grade programmable logic controller (PLC) as its core, paired with a color touchscreen display as the human-machine interface. The CNC system is connected to the servo motor drivers of the crawler drive and the drill-tapping motor drivers via communication cables. This allows it to receive machining parameters input by the operator and precisely control the crawler's speed and position, as well as the drill-tapping motor's speed, forward / reverse rotation, and operating mode according to preset programs. The CNC system also features fault diagnosis, alarm prompts, and machining data recording and query functions, facilitating operator monitoring and management of the equipment's operating status.
