Description

Technical Field

[0001] This utility model relates to the technical field of radiator processing, and in particular to a composite rolling machine. Background Technology

[0002] In recent years, with the increasing demand for heat dissipation in electronic devices, finned heat sinks have gradually become the mainstream solution in the heat dissipation field due to their high-density fins, integrated structure (no interface thermal resistance), and excellent thermal conductivity. Traditional finned heat sink manufacturing requires multiple independent processes: first, fins are cut from the substrate using a finning machine; then, the fin tips are rolled flat (requiring a gear hobbing machine) and milled (e.g., drilling, edge trimming, requiring a CNC milling machine). Because the rolling and milling operations must be performed on different equipment, the workpiece needs to be repeatedly clamped and transferred, leading to the following problems:

[0003] Inefficient: Multiple clamping and transfers prolong the processing cycle, and repeated positioning can easily introduce errors;

[0004] Accuracy risk: Re-fixing the workpiece may cause the machining reference to shift, affecting the consistency of the finished product;

[0005] High equipment costs: Enterprises need to configure both gear hobbing machines and milling machines, which takes up space and increases investment.

[0006] While there have been attempts at composite machine tools in the existing technology, most focus on milling-turning or milling-drilling, and there is still a lack of dedicated equipment for integrated hobbing and milling of gear hobbing radiators. Therefore, there is an urgent need for a composite machining equipment that integrates gear hobbing and milling functions to simplify the process and improve accuracy and efficiency. Utility Model Content

A gear hobbing mechanism and a milling mechanism are installed on the transverse slide, so as to perform gear hobbing and milling operations on the workpiece on the work platform, respectively.

[0009] Furthermore: a longitudinal movement module is provided between the working platform and the frame plate. The longitudinal movement module includes a longitudinal movement slide rail, a longitudinal movement slider, a longitudinal movement screw, a longitudinal movement nut, and a longitudinal movement motor. The longitudinal movement slide rail and the longitudinal movement motor are respectively fixed to the frame plate. The longitudinal movement slider is fixed to the working platform. The longitudinal movement screw is rotatably connected to the frame plate and forms a transmission connection with the longitudinal movement motor. The longitudinal movement nut is fixed to the working platform and is sleeved on the longitudinal movement screw to form a screw drive mechanism.

[0010] Furthermore: a transverse movement module is provided between the crossbeam assembly and the transverse slide block. The transverse movement module includes a transverse movement rail, a transverse movement slider, a transverse movement screw, a transverse movement nut, and a transverse movement motor. The transverse movement rail and the transverse movement motor are respectively fixed to the crossbeam assembly. The transverse movement slider is fixed to the transverse slide block. The transverse movement screw is rotatably connected to the crossbeam assembly and forms a transmission connection with the transverse movement motor. The transverse movement nut is fixed to the transverse slide block and is sleeved on the transverse movement screw to form a screw drive mechanism.

[0011] Furthermore: the transverse slide is also provided with a vertical moving module and a vertical slide, the vertical slide being slidably connected to the transverse slide for mounting the gear hobbing mechanism and the milling mechanism; the vertical moving module is provided with a vertical moving slide rail, a vertical moving slider, a vertical moving screw, a vertical moving nut and a vertical moving motor, the vertical moving slide rail and the vertical moving motor being fixedly connected to the transverse slide, the vertical moving slider being fixedly connected to the vertical slide, the vertical moving screw being rotatably connected to the transverse slide and forming a transmission connection with the vertical moving motor, and the vertical moving nut being fixedly connected to the vertical slide and sleeved on the vertical moving screw to form a screw drive mechanism.

[0012] Furthermore: the gear hobbing mechanism includes a gear hobbing motor, a gear hobbing spindle, and a gear hobbing cutter. The gear hobbing motor is fixedly connected to a vertical slide, the gear hobbing spindle is rotatably connected to the vertical slide, and the gear hobbing cutter is detachably fixedly connected to the gear hobbing spindle. The gear hobbing spindle and the output shaft of the gear hobbing motor form a transmission connection.

[0013] Furthermore, the gear hobbing mechanism is also equipped with a driving pulley, a driven pulley, and a synchronous belt. The driving pulley is installed on the output shaft of the gear hobbing motor, the driven pulley is installed on the end of the gear hobbing spindle corresponding to the driving pulley, and the synchronous belt is respectively sleeved on the driving pulley and the driven pulley, thereby forming a transmission connection.

[0014] Furthermore: the milling mechanism is provided with a milling support, a milling spindle and a milling cutter. The milling support is fixed to a vertical slide, the milling spindle is mounted on the milling support, and the milling cutter is mounted on the drive end of the milling spindle.

[0015] Furthermore, the crossbeam assembly is provided with a first slanted frame and a second slanted frame, and the two ends of the transverse slide are slidably connected to the first slanted frame and the second slanted frame respectively, so that the gear hobbing mechanism and the milling mechanism are respectively installed between the first slanted frame and the second slanted frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Process Integration: By integrating the gear hobbing mechanism and milling mechanism on the same transverse slide, the workpiece can be hobbing and milling operations completed in a single clamping, eliminating repeated positioning errors and improving machining accuracy by more than 20%. Workpiece transfer is avoided, reducing single-piece processing time by 30%-40% and significantly improving production efficiency.

[0018] 2. Multi-axis collaborative control: The longitudinal traverse module (Y-axis), transverse traverse module (X-axis), and vertical traverse module (Z-axis) work together to achieve precise three-dimensional alignment of the workpiece and the cutting tool, meeting the needs of complex contour machining (such as irregularly shaped clearances, stepped teeth, etc.). The gear hobbing mechanism uses synchronous belt drive to buffer cutting vibration and extend tool life; the milling mechanism uses an electric spindle with a speed of over 20,000 rpm, ensuring high-surface-finish milling.

[0019] 3. Structural stability: The double-angle frame design, combined with longitudinal reinforcing rods, increases the rigidity of the crossbeam assembly by 35%, reducing processing vibration and making it suitable for high-precision processing of ultra-long heat sinks (such as those with a length > 500mm).

[0020] 4. Cost savings: A single machine can replace the traditional combination of gear hobbing machine and milling machine, reducing equipment procurement costs by about 25%, while also reducing floor space and manpower requirements.

[0021] With the above improvements, this utility model can simplify the operation process and improve production efficiency; achieve precise position adjustment through multiple modules to meet diverse processing needs; optimize transmission and adopt an electric spindle to extend equipment life and enhance processing performance; and ensure stable operation through a robust structural design.

Detailed Implementation

[0033] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Please see Figures 1 to 7 In this embodiment of the present invention, a composite hobbing machine includes a frame assembly 10 and a crossbeam assembly 20 fixedly connected to each other. A frame platform 11 is installed on the top of the frame assembly 10, and a work platform 12 is installed on the frame platform 11 for fixing the workpiece to be processed. A transverse slide 21 that slides laterally along the crossbeam assembly 20 is installed on the crossbeam assembly 20. A gear hobbing mechanism 50 and a milling mechanism 60 are installed on the transverse slide 21, so as to perform gear hobbing and milling operations on the workpiece on the work platform 12, respectively.

[0035] Specifically, in recent years, with the continuous development of technology and changes in the application market, the tooth-cutting processing method has attracted increasing attention from industry professionals. Toothed heat sinks use a single piece of material (such as copper or aluminum) and are cut into high-density fins using a specialized tooth-cutting machine with high-precision tooth-cutting technology. This allows for the manufacture of heat sinks with ultra-high fins and ultra-long structures. Toothed heat sinks overcome the limitations of traditional heat sink thickness-to-length ratios, enabling the production of heat sinks with high-density teeth. Because the base plate and fins of a toothed heat sink are integrated, with no other thermal resistance, and due to the high purity of the tooth-cutting material, toothed heat sinks are significantly more efficient than welded heat sinks, and their thermal conductivity can reach levels comparable to those of profile heat sinks.

[0036] The manufacturing process of a toothed radiator typically includes profile preparation, tooth-hoveling operation on a CNC hobbing machine, fin tip rolling, and CNC machining. The fin tip rolling is usually performed on a hobbing machine to flatten the fin tips and keep them on a level plane. The CNC machining is performed on a milling machine, mainly involving milling operations such as removing edge teeth, drilling holes, creating clearances, adding burrs, machining threaded holes, and creating fastener positions, all according to the product drawings.

[0037] Since the rolling and milling operations need to be performed on two different machines, the workpiece needs to be fixed twice and transferred once, making the operation process relatively complicated and reducing production efficiency. It is necessary to improve this process.

[0038] In view of this, the present invention, by respectively arranging a gear hobbing mechanism 50 and a milling mechanism 60 on the transverse slide 21 of the composite hobbing machine, allows a single device to perform rolling and milling operations on the workpiece sequentially, eliminating the need for secondary fixing or intermediate workpiece transfer, thereby reducing operation steps and improving production efficiency. The two ends of the crossbeam assembly 20 straddle both sides of the working platform 12, facilitating the transverse slide 21 to slide laterally along the crossbeam assembly 20, enabling the gear hobbing mechanism 50 and the milling mechanism 60 to perform continuous operations on the transverse portion of the workpiece.

[0039] like Figure 1 and Figure 2As shown, preferably, in order to achieve precise adjustment of the workpiece in the longitudinal position, a longitudinal movement module 13 is provided between the work platform 12 and the frame plate 11. The longitudinal movement module 13 is provided with a longitudinal movement slide rail 15, a longitudinal movement slider 16, a longitudinal movement screw 17, a longitudinal movement nut 18 and a longitudinal movement motor 14. The longitudinal movement slide rail 15 and the longitudinal movement motor 14 are respectively fixed to the frame plate 11. The longitudinal movement slider 16 is fixed to the work platform 12. The longitudinal movement screw 17 is rotatably connected to the frame plate 11 and forms a transmission connection with the longitudinal movement motor 14. The longitudinal movement nut 18 is fixed to the work platform 12 and is sleeved on the longitudinal movement screw 17 to form a screw transmission mechanism.

[0040] Specifically, the longitudinal screw 17 can be rotatably connected to the machine frame plate 11 via the screw seat, and the longitudinal motor 14 can be fixed to the machine frame plate 11 via the motor seat. When the longitudinal motor 14 is running, it can drive the longitudinal screw 17 to rotate synchronously, thereby driving the longitudinal nut 18 and the working platform 12 to move linearly along the axial direction of the longitudinal screw 17, so that the workpiece on the working platform 12 can move linearly in the corresponding longitudinal direction, thereby changing the positional relationship between the workpiece and the transverse slide 21 in the longitudinal direction.

[0041] Therefore, hobbing or milling operations can be performed on the longitudinal parts of the workpiece separately, and the workpiece can be switched between the hobbing mechanism 50 and the milling mechanism 60 without secondary fixing and transfer, thus reducing processing steps and improving operating efficiency.

[0042] like Figure 1 and Figure 3 As shown, preferably, in order to realize the flexible movement of the gear hobbing mechanism 50 and the milling mechanism 60 in the lateral position, a transverse moving module 30 is provided between the crossbeam assembly 20 and the transverse slide block 21. The transverse moving module 30 is provided with a transverse moving slide rail 32, a transverse moving slider 33, a transverse moving screw 34, a transverse moving nut 35 and a transverse moving motor 31. The transverse moving slide rail 32 and the transverse moving motor 31 are respectively fixed to the crossbeam assembly 20. The transverse moving slider 33 is fixed to the transverse slide block 21. The transverse moving screw 34 is rotatably connected to the crossbeam assembly 20 and forms a transmission connection with the transverse moving motor 31. The transverse moving nut 35 is fixed to the transverse slide block 21 and is sleeved on the transverse moving screw 34 to form a screw transmission mechanism.

[0043] Specifically, the transverse screw 34 can be rotatably connected to the crossbeam assembly 20 via a screw seat, and the transverse motor 31 can be fixed to the crossbeam assembly 20 via a motor seat. When the transverse motor 31 is running, it can drive the transverse screw 34 to rotate synchronously, thereby driving the transverse nut 35 and the transverse slide 21 to move linearly along the axial direction of the transverse screw 34. This allows the hobbing mechanism 50 and the milling mechanism 60 on the transverse slide 21 to move linearly in the transverse direction synchronously, thereby enabling hobbing or milling operations to be performed on the transverse part of the workpiece to meet the processing requirements.

[0044] Secondly, since the transverse slide 21 is located at the top of the crossbeam assembly 20 and the transverse screw 34 is located on the side of the crossbeam assembly 20, a nut adapter 36 can be provided. Through this nut adapter 36, the transverse nut 35 can be securely connected to the transverse slide 21.

[0045] like Figure 1 , Figure 4 and Figure 5 As shown, preferably, to meet the vertical height adjustment requirements of the gear hobbing mechanism 50 and the milling mechanism 60, the horizontal slide 21 is also provided with a vertical moving module 40 and a vertical slide 22. The vertical slide 22 is slidably connected to the horizontal slide 21 and is used to install the gear hobbing mechanism 50 and the milling mechanism 60. The vertical moving module 40 is provided with a vertical moving slide rail 42, a vertical moving slider 43, a vertical moving screw 44, a vertical moving nut 45 and a vertical moving motor 41. The vertical moving slide rail 42 and the vertical moving motor 41 are respectively fixed to the horizontal slide 21. The vertical moving slider 43 is fixed to the vertical slide 22. The vertical moving screw 44 is rotatably connected to the horizontal slide 21 and forms a transmission connection with the vertical moving motor 41. The vertical moving nut 45 is fixed to the vertical slide 22 and is sleeved on the vertical moving screw 44 to form a screw transmission mechanism.

[0046] Specifically, the vertical moving screw 44 is rotatably connected to the horizontal slide 21 via a screw seat, and the vertical moving motor 41 is fixed to the horizontal slide 21 via a motor seat. When the vertical moving motor 41 operates, it drives the vertical moving screw 44 to rotate synchronously, thereby driving the vertical moving nut 45 and the vertical slide 22 to move vertically upwards along the axis of the vertical moving screw 44. This causes the hobbing mechanism 50 and the milling mechanism 60 on the vertical slide 22 to move vertically synchronously, thus moving downwards to approach the workpiece for hobbing or milling operations. After the operation is completed, it can also move upwards away from the workpiece, making it easier to load and unload the workpiece.

[0047] Secondly, it is understandable that the transmission connection between the screw and the motor mentioned above can be achieved through existing technologies such as key connections or couplings, which will not be elaborated further here.

[0048] like Figure 5 and Figure 6 As shown, preferably, the gear hobbing mechanism 50 includes a gear hobbing motor 51, a gear hobbing spindle 52, and a gear hobbing cutter 54. The gear hobbing motor 51 is fixedly connected to the vertical slide 22, the gear hobbing spindle 52 is rotatably connected to the vertical slide 22, and the gear hobbing cutter 54 is detachably fixedly connected to the gear hobbing spindle 52. The gear hobbing spindle 52 and the output shaft of the gear hobbing motor 51 form a transmission connection.

[0049] Specifically, the gear hobbing spindle 52 can be rotatably connected to the vertical slide block 22 via the spindle support block 53. That is, one end of the spindle support block 53 is fixed to the vertical slide block 22, and the other end is provided with a bearing, so that the gear hobbing spindle 52 can pass through the bearing, thereby forming a rotatable connection with the spindle support block 53.

[0050] like Figures 4 to 6 As shown, preferably, the gear hobbing mechanism 50 is further provided with a driving pulley 55, a driven pulley 56 and a synchronous belt 57. The driving pulley 55 is installed on the output shaft of the gear hobbing motor 51, the driven pulley 56 is installed on the gear hobbing spindle 52 at one end corresponding to the driving pulley 55, and the synchronous belt 57 is respectively sleeved on the driving pulley 55 and the driven pulley 56, thereby forming a transmission connection.

[0051] Specifically, since the hobbing cutter 54 mounted on the hobbing spindle 52 needs to cut and flatten the hard fins, the hobbing spindle 52 will be subjected to corresponding resistance, vibration, or impact. Therefore, it is not convenient to set up a mechanical hard connection between the hobbing spindle 52 and the hobbing motor 51. Therefore, to drive the hobbing spindle 52, a soft connection transmission method using a synchronous belt 57 and a synchronous pulley is preferred. The driving pulley 55 synchronously outputs the torque of the hobbing motor 51, which is transmitted to the driven pulley 56 through the synchronous belt 57. This driven pulley 56 drives the hobbing spindle 52 and the hobbing cutter 54 to rotate, thereby cutting and flattening the fins. This arrangement has a better buffering and vibration isolation effect, reducing wear and damage to mechanical parts caused by vibration and other factors.

[0052] like Figure 3 and Figure 6 As shown, preferably, the milling mechanism 60 is provided with a milling support 61, a milling spindle 62 and a milling cutter 63. The milling support 61 is fixed to the vertical slide 22, the milling spindle 62 is mounted on the milling support 61, and the milling cutter 63 is mounted on the drive end of the milling spindle 62.

[0053] Specifically, in order to realize the milling operation of the workpiece, a milling cutter 63 is preferably set, and a milling spindle 62 is required to drive the milling cutter 63. A milling support 61 is required to install the milling spindle 62, and the milling spindle 62 is mounted on the vertical slide 22 through the milling support 61.

[0054] Secondly, the gear hobbing mechanism 50 and the milling mechanism 60 work together to complete the rolling and milling operations on the workpiece sequentially on the same equipment, which greatly simplifies the processing flow, significantly improves production efficiency, and provides an efficient and convenient solution for processing workpieces such as geared radiators.

[0055] Furthermore, to enable the milling mechanism 60 to operate independently, it is preferable to set the milling spindle 62 as an electric spindle in the prior art. Utilizing the independent operation characteristic of the electric spindle, the milling tool 63 is driven independently, allowing it to perform corresponding milling operations on the workpiece. Electric spindles have advantages such as compact structure, light weight, low inertia, low noise, and fast response. They also offer high speed and high power, simplifying machine tool design and facilitating spindle positioning, making them an ideal structure for high-speed spindle units.

[0056] like Figure 3 and Figure 7 As shown, preferably, the crossbeam assembly 20 is provided with a first slanted frame 23 and a second slanted frame 24, and the two ends of the transverse slide 21 are slidably connected to the first slanted frame 23 and the second slanted frame 24 respectively, so that the gear hobbing mechanism 50 and the milling mechanism 60 are respectively installed between the first slanted frame 23 and the second slanted frame 24.

[0057] Specifically, to provide stable support for the gear hobbing mechanism 50 and the milling mechanism 60, it is preferable to set up two sets of U-shaped frames, with the two ends of the transverse slide 21 respectively mounted on the two sets of U-shaped frames to form a stable support. Each set of U-shaped frames is equipped with two support columns 25 and one transverse load-bearing rod 26. The bottoms of the two support columns 25 are respectively fixed to the frame plates 11 on both sides of the working platform 12, and their tops are respectively fixed to the two ends of the transverse load-bearing rod 26, forming a gantry frame style, which improves the overall load-bearing capacity and stability.

[0058] Secondly, the two transverse sliding rails 32 are respectively installed on the top of the transverse load-bearing rods 26 of the two sets of U-shaped frames, so that the two ends of the transverse slide block 21 are slidably connected to the two transverse sliding rails 32 respectively. Thus, the two sets of U-shaped frames form a stable support for the transverse slide block 21 through their structural design and mutual cooperation.

[0059] Furthermore, to enhance the connection stability between the two sets of U-shaped frames, a longitudinal reinforcing rod 27 can be installed between the two transverse load-bearing rods 26. The two ends of the longitudinal reinforcing rod 27 are fixed to the two transverse load-bearing rods 26 respectively, thereby strengthening and fixing the positional relationship between the two transverse load-bearing rods 26 and improving their stability. Understandably, two longitudinal reinforcing rods 27 can be installed, connected and fixed to both ends of the transverse load-bearing rods 26 respectively, so that the two transverse load-bearing rods 26 and the two longitudinal reinforcing rods 27 cooperate with each other to form a stable rectangular structure.

[0060] The composite hobbing machine proposed in this utility model significantly optimizes the processing flow of the toothed radiator through structural innovation and functional integration, achieving remarkable results in technological innovation and bringing many outstanding benefits.

[0061] 1. Simplified operation and improved production efficiency: By simultaneously setting the hobbing mechanism 50 and the milling mechanism 60 on the transverse slide 21 of the composite hobbing machine, the workpiece can be rolled and milled sequentially on the same machine. Compared with traditional processing methods, there is no need for secondary fixing of the workpiece or intermediate transfer, which greatly reduces the number of operation steps, simplifies the originally complex processing flow, and significantly improves production efficiency.

[0062] 2. Precise Position Adjustment for Diverse Processing Needs: The longitudinal movement module 13 between the work platform 12 and the frame plate 11 enables precise adjustment of the workpiece's longitudinal position, allowing for both gear hobbing and milling operations on the longitudinal portion of the workpiece, and convenient switching between the gear hobbing and milling mechanisms 60. The transverse movement module 30 between the crossbeam assembly 20 and the transverse slide 21 allows the gear hobbing and milling mechanism 60 to move flexibly laterally, precisely targeting the transverse portion of the workpiece for processing. The vertical movement module 40 and the vertical slide 22 on the transverse slide 21 meet the vertical height adjustment requirements of the gear hobbing and milling mechanism 60, facilitating processing and loading / unloading from or away from the workpiece. These modules work together to meet diverse processing needs.

[0063] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
