[0002] A milling machine is a machine tool primarily used for metal processing. It cuts and processes workpieces using the rotational motion of a milling cutter and the feed motion of the workpiece, producing various parts such as planes, steps, grooves, shaped surfaces, and gears. Milling machines come in various types, including horizontal and vertical milling machines. Their working principle utilizes the multi-edged cutting of the milling cutter, improving processing efficiency and precision. They are widely used in many industries such as machinery manufacturing, mold making, and automobile manufacturing, and are crucial equipment for achieving precise machining, ensuring product quality, and improving production efficiency.

[0003] In the current screw machining field, milling machines are key equipment. However, existing screw milling machines have some problems that urgently need to be solved.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Combined with appendix Figure 2 A milling machine for machining metal screws includes: a bed 1 with a stable base, which is integrally formed from metal material and used to support the various components of the milling machine. The bottom of the base structure of the bed 1 is provided with a shock-absorbing pad 14, which can effectively reduce the vibration generated during the operation of the milling machine, improve the machining stability, and thus improve the machining accuracy of the metal screw.

[0026] Combined with appendix Figure 1 Appendix Figure 3 The bed frame 1 is equipped with a heightening plate 2 and a water-blocking ring 3 at the edge. The bed frame 1 is equipped with a water processor. There is a water inlet between the heightening plate 2 and the water-blocking ring 3 that communicates with the water processor. The water inlet is equipped with a filter screen 15, which can filter impurities in the water, prevent impurities from entering the water processor, extend the service life of the water processor, and ensure its normal operation.

[0027] Combined with appendix Figure 1 Appendix Figure 3 The machining base 4 is mounted on the extension plate 2 and can move along the X and Y axes. The machining base 4 is driven by an electric slide rail 5 fixed on the extension plate 2. The milling spindle 6 is rotatably mounted above the machining base 4 and is driven by a speed-regulating motor 7. The machining base 4 is equipped with a positioning fixture, which consists of four arc-shaped clamping blocks 16. The arc-shaped clamping blocks 16 are arranged around the milling spindle 6 and are driven to move relative to each other in pairs through a lead screw and nut mechanism 17. This can flexibly and stably limit the metal screw, ensure that the screw position is fixed during the machining process, and improve machining accuracy.

[0028] Combined with appendix Figure 1The automatic tool changing device includes a tool magazine 8 and a tool changing robotic arm 9. The tool magazine 8 can accommodate various sizes of milling cutters. The automatic tool changing device is also equipped with a tool detection sensor installed in the tool magazine 8 to detect tool wear and installation status. It can monitor tool wear and installation status in real time and promptly remind users to replace or adjust the tools to ensure machining quality and efficiency.

[0029] Combined with appendix Figure 1 Appendix Figure 3 The cooling system includes a coolant tank 10, a coolant pump 11, and a nozzle 12. The coolant pump 11 is connected to the coolant tank 10 and the nozzle 12 through a pipe 13. The coolant pump 11 sprays coolant through the nozzle 12 to the processing area. The coolant tank 10 of the cooling system is equipped with a liquid level sensor and a temperature sensor, which are used to detect the coolant level and temperature, respectively, control the start and stop of the coolant pump 11 and the replenishment of coolant, ensure the stable operation of the cooling system, and provide good cooling conditions for processing.

[0030] Combined with appendix Figure 4 The nozzle 12 has an adjustable angle and spray position. The nozzle 12 is equipped with a universal tube 18, which can be rotated at any angle, enabling more precise spraying of coolant onto the processing area, enhancing the cooling effect and meeting different processing needs.

[0031] The specific implementation of this utility model is as follows: First, the milling machine is connected to an external power supply and connected to the machining control system. The metal screw to be processed is placed on the milling spindle 6 of the machining base 4, which is located between four arc-shaped clamping blocks 16. The arc-shaped clamping blocks 16 are driven to move relative to each other through the lead screw and nut mechanism 17, so that they are close to the metal screw and effectively limit its movement, while ensuring that the metal screw can rotate.

[0032] According to the machining requirements of the screw, the machining control system controls the automatic tool changing device. The tool changing robot arm 9 selects a suitable tool from the tool magazine 8, which can hold various milling cutters of different specifications, based on the tool status detected by the tool detection sensor, and brings it close to the metal screw. The speed-regulating motor 7 drives the milling spindle 6 to rotate the metal screw. At the same time, the electric slide rail 5 drives the metal screw on the machining seat 4 to move along the X and Y axes, realizing the milling machining of the screw.

[0033] During processing, the cooling system operates synchronously. The cooling pump 11 draws coolant from the coolant tank 10, delivers it through the pipe 13 to the nozzle 12, and then, through the rotatable universal tube 18, precisely sprays the coolant onto the processing area to achieve a cooling effect. The liquid level sensor and temperature sensor in the coolant tank 10 monitor the coolant status in real time, controlling the start and stop of the cooling pump 11 and the replenishment of coolant.

[0034] Meanwhile, the coolant containing chips generated during processing, blocked by the water baffle ring 3, flows into the water processor inside the machine bed 1 through the inlet of the filter screen 15 located between the riser plate 2 and the water baffle ring 3.
