Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically a multi-station independent machining center machine tool. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. Typically, the rotation of the milling cutter is the primary motion, while the movement of the workpiece and the milling cutter constitutes the feed motion. It can machine planes, grooves, various curved surfaces, gears, and more. A milling machine is a machine tool that uses a milling cutter to perform milling operations on a workpiece.

[0003] Currently, traditional CNC milling machines mostly adopt a single-head structure, which can only process one workpiece at a time, resulting in low efficiency. Although there are multi-head machine tools, most heads are linked for control, which cannot achieve truly independent movement and processing, resulting in poor flexibility and difficulty in adapting to the production needs of multiple varieties and small batches. Therefore, a multi-station machine tool with independent machining heads is proposed to solve the above problems. Utility Model Content

Each of the three machine head covers is equipped with a trailer box on its top. Each trailer box corresponds to three X-axis control structures that independently control the milling machine inside the machine head cover. Each of the three machine head covers is equipped with a probe that extends to the bottom at one end.

[0008] Furthermore, the X-axis control structure includes a servo motor, a drive shaft, a cable chain, two guide rails, two sets of guide rail sliders, a nut seat, and a fixed seat. The servo motor is fixedly installed inside the concave groove on the front of the arched beam, and the fixed seat is also fixedly installed inside the concave groove on the front of the arched beam. The two ends of the drive shaft are respectively located between the output end of the servo motor and the fixed seat.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-7This embodiment of a multi-station independent machining center includes a machine cover 1 and an electrical control box 2. The electrical control box 2 is located at the top back of the machine cover 1, and is integrally formed with the machine cover 1 with a sheet metal partition separating the electrical and mechanical parts, thereby improving safety and heat dissipation efficiency. The front of the machine cover 1 has an electrical control cabinet door 4 for easy maintenance and operation. A touch screen display 3 is also provided on one side of the front of the machine cover 1 for human-machine interaction and program control. An alarm light 5 is provided at the top corner of the machine cover 1 to indicate when the equipment malfunctions. The system provides a visual alarm to enhance operational safety. Inside the housing 1, there is a base 8. The top of the base 8 is equipped with an arched beam 7. The front of the arched beam 7 has a concave groove 11 for arranging the transmission structure and cables. Three machine head covers 12 are located on the front of the arched beam 7, and each machine head cover 12 is equipped with a milling machine 15. An X-axis control structure 10 is provided between the three machine head covers 12 and the arched beam 7 to control the three milling machines 15 to move independently along the X-axis, enabling multi-station independent processing. Each of the three head covers 12 has a tray 13 on its top. Each tray 13 corresponds to one of the three X-axis control structures 10, which independently control the milling machine 15 inside the head cover 12. The tray 13 is used to store and protect moving parts such as cables and oil pipes to avoid interference and wear. Each of the three head covers 12 has a probe 14 that extends to the bottom. The probe is used to detect the workpiece position and processing status in real time during the processing to achieve high-precision processing and automated compensation.

[0017] The end of the milling machine 15 also extends out of the bottom of the head cover 12, allowing for direct milling of the workpiece. It has a compact structure and good rigidity.

[0018] It should be noted that three tool magazine slides 9 are provided on the top of the base 8 and at the bottom of the arched crossbeam 7, and each tool magazine slide 9 is correspondingly located at the bottom of the three machine head covers 12, which can automatically change tools during the processing. A tool loading container 16 is fixedly provided on the top of each of the three tool magazine slides 9, and several tools 17 are inserted into the top of each of the three tool loading containers 16, so as to realize rapid tool switching and adapt to complex processing tasks.

[0019] In this embodiment, the X-axis control structure 10 includes a servo motor 101, a drive shaft 102, a cable chain 103, two guide rails 104, two sets of guide rail sliders 105, a nut seat 106, and a fixed seat 107. The servo motor 101 and the fixed seat 107 are fixed in the concave groove 11. The drive shaft 102 connects the output end of the servo motor 101 to the fixed seat 107. The servo motor 101 drives the drive shaft 102 to rotate, which in turn drives the nut seat 106 to move axially along the drive shaft 102, thereby pushing the head cover 12 to slide along the guide rail 104 to achieve precise positioning. The cable chain 103 is arranged on the top of the arched crossbeam 7 to protect the cable.

[0020] The X-axis control structure 10 consists of three sets, each independently controlling one of the three machine head covers 12. The drive shaft 102 is divided into three sections arranged in the concave groove 11, ensuring that they do not interfere with each other and that each machine head moves independently. The cable chains 103 are installed on the three cable boxes 13 respectively, further protecting the moving cables.

[0021] In this embodiment, the water tank 6 is located inside the machine cover 1 on one side, and two chip buckets are placed on its top. The back of the machine cover 1 above the water tank 6 is provided with a chip discharge hole. The metal chips generated during the processing are discharged through the chip discharge hole, which is convenient for collection and cleaning, and keeps the processing environment clean.

[0022] The working principle of the above embodiments is as follows: Operators input the machining program via the touchscreen display 3, setting the machining tasks and paths for each milling head. Upon receiving the instructions, the electrical control box 2 controls the servo motors 101 to start, driving the drive shaft 102 to rotate. This, via the nut seat 106, moves the milling head cover 12 along the guide rail 104, achieving precise X-axis positioning. Each milling machine 15 performs milling operations according to the program instructions. The probe 14 monitors the machining status in real time and feeds back data to the control system, achieving closed-loop control of the machining process. The tool magazine slide 9 automatically switches tools 17 according to program requirements, improving machining flexibility and efficiency. Chips generated during machining are discharged through the chip discharge hole and collected by the chip bucket, keeping the equipment clean. The alarm light 5 sounds an alarm when the equipment malfunctions, prompting the operator to handle the situation promptly. The entire system, through independent control of multiple milling heads, automated tool changing, and real-time monitoring, achieves efficient, precise, and flexible simultaneous machining of multiple workpieces, suitable for modern intelligent manufacturing scenarios involving multiple varieties and small batches.
