Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, and in particular to a heat-assisted milling device. Background Technology

[0002] Currently, when milling workpieces, preheating is required to soften them for machining. However, with existing heat-assisted machining methods, whether using integral or separate milling cutters, the workpiece material is heated first, followed by cutting. This results in a significant distance between the heating and cutting areas, and a noticeable time difference between heating and cutting. During this time, the workpiece experiences significant heat loss, leading to substantial heat dissipation in the heating area and low material softening efficiency. Therefore, a new type of heat-assisted milling device is urgently needed to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a heat-assisted milling device to solve the problems existing in the prior art, greatly reduce the time and space delay between heating and cutting, improve the heat source utilization rate, and effectively reduce the heat source power requirement and the probability of thermal damage to the workpiece after processing.

[0004] To achieve the above objectives, the present invention provides the following solution:

[0005] The present invention provides a heat-assisted milling device, including a milling head and a plurality of heat source output devices. The milling head includes a plurality of milling cutter blades arranged around the circumference. The number of heat source output devices is the same as the number of milling cutter blades. One heat source output device corresponds to one milling cutter blade, and the heating area formed by the output end of the heat source output device on the workpiece is always located on the movement trajectory of the front side of the milling cutter blade.

[0006] Preferably, each of the heat source output devices is fixed to the milling cutter head and rotates with the milling cutter head.

[0007] Preferably, the heat source output device is an electric arc plasma generator or a laser collimator.

[0008] Preferably, when the heat source output device is an arc plasma generator, it is electrically connected to an external power source through wires and a conductive slip ring, and the conductive slip ring is coaxially arranged directly above the milling cutter head;

[0009] When the heat source output device is a laser collimator, light is transmitted through an optical fiber and an external stationary light source, with the optical fiber slip ring coaxially positioned directly above the milling cutter head.

[0010] The present invention achieves the following technical effects compared to the prior art:

[0011] The heat-assisted milling device provided by this invention is equipped with an independent heat source output device in front of each milling cutter insert. As the milling cutter head rotates, the heat source output device heats the area to be processed in front of each milling cutter insert. This can minimize the time difference between the heating and cutting steps, improve the heat source utilization rate, and effectively reduce the heat source power requirement and the probability of thermal damage to the workpiece after processing.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Figure 3This is a plan view of a traditional milling device;

[0023] Figure 4 This diagram shows the positional relationship between the heating zone formed on the workpiece and the milling cutter head in a traditional milling machine. In traditional milling machines, the workpiece material is heated first, and the cutting tool cuts afterward. This results in a long distance between the heating zone and the cutting zone, and a significant time difference between heating and cutting. During this time, the heat loss of the workpiece is significant, leading to substantial heat dissipation in the heating zone and low material softening efficiency after heating.

[0024] The purpose of this invention is to provide a heat-assisted milling device, such as... Figures 1-2 As shown, the milling head 11 includes a milling cutter head 11 and multiple heat source output devices 13. The milling cutter head 11 includes multiple milling cutter blades 12 arranged around the circumference. The number of heat source output devices 13 is the same as the number of milling cutter blades 12. One heat source output device 13 is set to correspond to one milling cutter blade 12, and the heating area 14 formed by the output end of the heat source output device 13 on the workpiece 100 is always located on the movement trajectory in front of the milling cutter blade 12.

[0025] The heat-assisted milling device provided by the present invention is equipped with an independent heat source output device 13 in front of each milling cutter blade 12. The milling cutter blade 12 rotates with the milling head 11, and the heat source output device 13 heats the area to be processed in front of each milling cutter blade 12. This can minimize the time difference between the heating and cutting steps, improve the heat source utilization rate, and effectively reduce the heat source power requirement and the probability of thermal damage to the workpiece 100 after processing.

[0026] The distance between the heating zone 14 and the milling cutter insert 12 can be reduced to 0.05 mm.

[0027] In some embodiments, each heat source output device 13 is fixed on the milling head 11 and rotates with the milling head 11. A number of heat source output devices 13 are provided on a milling head 11 corresponding to each milling cutter blade 12, and the multiple heat source output devices 13 are arranged around the circumference. In a preferred embodiment, the heat source output device 13 can be fixed on the milling head 11 by means of clamping. Of course, in other embodiments, any fastening structure in the prior art can also be used to fix the heat source output device 13.

[0028] In some embodiments, the milling head 11 is a split head.

[0029] In some embodiments, the heat source output device 13 is an arc plasma generator or a laser collimator.

[0030] When the heat source output device 13 is an electric arc plasma generator, it is electrically connected to an external power source through wires and a conductive slip ring. The conductive slip ring is coaxially arranged with the milling cutter head 11.

[0031] When the heat source output device 13 is a laser collimator, light is transmitted through an optical fiber and an optical fiber slip ring to a stationary external light source. The optical fiber slip ring is coaxially arranged with the milling cutter head 11.

[0032] Specifically, conductive slip rings or fiber optic slip rings are collectively referred to as slip rings. The slip ring can be fitted onto the tool holder above the milling cutter head 11. In one embodiment, the rotor of the slip ring is connected to the tool holder and the heat source output device 13, and the stator is connected to an external static power source or static light source.

[0033] One heat source output device 13 can be configured to correspond to one slip ring, or multiple heat source output devices 13 can be configured to correspond to the same slip ring. Of course, in other embodiments, other existing technologies can also be used, as long as a stationary power source and light source can stably supply power and light to the rotating heat source output device 13.

[0034] In other embodiments, when the heat source output device 13 is an independent device with its own power supply or light source, the heat source output device 13 can be directly fastened to the milling cutter head 11, thereby eliminating the need for the slip ring structure in the above embodiments.

[0035] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
