Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a milling and turning machine. Background Technology

[0002] Traditional lathes are an indispensable tool in the field of machining, primarily used for processing workpieces with rotating characteristics. These machine tools typically include a chuck to hold one end of the workpiece, while the other end is machined by a cutting tool to achieve surface finishing such as external diameters, internal holes, and threads. Traditional lathes are generally equipped with a cutting tool, which feeds along the axial (Z-axis) and radial (X-axis) directions of the workpiece to complete the required machining tasks.

[0003] However, traditional lathes have some obvious limitations. First, due to their structural limitations, they can only perform turning operations and cannot perform other types of machining such as milling. This means that when the workpiece has a more complex geometry, it is necessary to switch to a specialized milling machine or other machining equipment for subsequent processing, resulting in low production efficiency and increased processing costs. Second, the structure of traditional lathes is relatively simple and does not make full use of available space resources, resulting in a large overall size of the equipment and poor flexibility in certain situations.

[0004] In recent years, with the development of the manufacturing industry and the increasing demands for processing precision and efficiency, more and more manufacturers are seeking high-efficiency processing equipment that integrates multiple processing functions. As a result, some so-called "composite machining centers" have emerged on the market. These centers combine turning, milling, and other processing methods, performing multiple machining processes on a single machine, greatly improving processing flexibility and efficiency. However, these composite machining centers are often complex in structure, expensive, and have limited processing range.

[0005] Therefore, developing a milling-turning machine that retains the basic functions of a traditional lathe while expanding its machining range, especially by adding milling capabilities, has become one of the urgent technical problems to be solved. This invention aims to provide a milling-turning machine that overcomes the shortcomings of existing technologies, improves machining efficiency, reduces machining costs, and meets the needs of modern manufacturing for multifunctional, high-precision machining equipment.

[0033] Traditional lathes are an indispensable tool in the field of machining, primarily used for processing workpieces with rotating characteristics. These machine tools typically include a chuck to hold one end of the workpiece, while the other end is machined by a cutting tool to achieve surface finishing such as external diameters, internal holes, and threads. Traditional lathes are generally equipped with a cutting tool, which feeds along the axial (Z-axis) and radial (X-axis) directions of the workpiece to complete the required machining tasks.

[0034] However, traditional lathes have some obvious limitations. First, due to their structural limitations, they can only perform turning operations and cannot perform other types of machining such as milling. This means that when the workpiece has a more complex geometry, it is necessary to switch to a specialized milling machine or other machining equipment for subsequent processing, resulting in low production efficiency and increased processing costs.

[0035] In recent years, with the development of the manufacturing industry and the increasing demands for processing precision and efficiency, more and more manufacturers are seeking high-efficiency processing equipment that integrates multiple processing functions. As a result, some so-called "composite machining centers" have emerged on the market. These centers combine turning, milling, and other processing methods, performing multiple machining processes on a single machine, greatly improving processing flexibility and efficiency. However, these composite machining centers are often complex in structure, expensive, and have limited processing range.

[0036] Therefore, developing a milling-turning machine that retains the basic functions of a traditional lathe while expanding its machining range, especially by adding milling capabilities, has become one of the urgent technical problems to be solved. This invention aims to provide a milling-turning machine that overcomes the shortcomings of existing technologies, improves machining efficiency, reduces machining costs, and meets the needs of modern manufacturing for multifunctional, high-precision machining equipment.

[0037] Therefore, such as Figures 1 to 3As shown, this utility model proposes a milling and turning machine, including a lathe 100 and a milling assembly 200 mounted on the lathe 100. The lathe 100 includes a chuck 110, a worktable 120, a first drive assembly, and a cutting tool 130. The chuck 110 clamps the workpiece and drives it to rotate above the worktable 120. The first drive assembly connects to and drives the cutting tool 130 to move along the X-axis of the worktable 120 to adjust the feed rate to the workpiece, and also drives the cutting tool 130 to move along the Z-axis of the worktable 120 to perform cutting on the outer peripheral wall of the workpiece. It should be noted that the first drive assembly is a conventional drive structure in the lathe 100 (not shown in the figure), used to drive the worktable 120 to move along the X and Z axes, or to drive the worktable 120 to move along the X, Y, and Z axes. Refer to the drive structure of a hand-operated lathe 100 or a CNC lathe 100; it will not be described in detail here. Specifically, the milling assembly 200 is connected to the worktable 120. Therefore, under the drive of the first drive assembly, the worktable 120, the cutting tool 130, and the milling assembly 200 move together. Further, the milling assembly 200 includes a second drive assembly 210, a first spindle 220, and a second spindle 230. The first spindle 220 and the second spindle 230 are arranged along the X-axis and Z-axis, respectively. The second drive assembly 210 connects to and drives the first spindle 220 and the second spindle 230 to move along the Y-axis direction of the worktable 120. One of the first spindle 220 and the second spindle 230 is used to perform milling operations on the workpiece. It should be noted that adding a milling assembly 200 to the lathe 100 not only retains the original turning function but also expands the milling capability. The milling assembly 200 includes a second drive assembly 210, a first spindle 220, and a second spindle 230. The first spindle 220 and the second spindle 230 are arranged along the X-axis and Z-axis respectively, and can move along the Y-axis via the second drive assembly 210. Driven by the worktable 120, milling can be performed on different parts of the workpiece. This allows for the machining of parts with various shape requirements without changing the workpiece clamping state, significantly improving machining flexibility and efficiency. In some embodiments of this invention, the center lines of the first spindle 220 and the second spindle 230 are located on the same horizontal plane and intersect. It is easy to understand that, due to the design that the center lines of the first spindle 220 and the second spindle 230 are on the same horizontal plane and intersect, the operator can complete the tool setting of the first spindle 220 and the second spindle 230 with the workpiece in the X0Z axis plane at one time. When performing milling, the operator can flexibly choose which spindle to use, which increases the machining flexibility. As a result, it is more convenient to switch the machining of the outer peripheral wall of the workpiece and the end face machining away from the chuck 110. This allows for complex machining path planning to be realized in a small space, improving the diversity and efficiency of machining.

[0038] Refer to Figure 1In some embodiments of this utility model, the chuck 110 has a fixing groove 1101 at its center for fixing one end of the workpiece, ensuring that the workpiece can be stably clamped on the chuck 110 and improving the stability during the processing. Furthermore, the fixing groove 1101 is square or cylindrical, which can adapt to workpiece ends of different shapes, enhancing the versatility and adaptability of the equipment.

[0039] Refer to Figure 1 and Figure 2 In some embodiments of this utility model, the worktable 120 is connected to a connecting seat 300, and the turning tool 130 and the milling assembly 200 are respectively connected to both sides of the connecting seat 300, which helps to ensure the relative positional relationship between the two and facilitates linkage control. This design helps to simplify the equipment structure, reduce the space occupied, and make operation more convenient. Optionally, the center lines of the first spindle 220, the second spindle 230, and the turning tool 130 are located on the same horizontal plane and intersect vertically in sequence. The operator can complete the tool setting of the turning tool 130, the first spindle 220, and the second spindle 230 with the workpiece in the X0Z axis plane at one time. During processing, the operator can flexibly choose to use turning or choose which spindle to use for milling, which increases the processing flexibility. Thus, it is more convenient to switch to milling the outer peripheral wall of the workpiece, end face milling away from the chuck 110, and turning the outer peripheral wall of the workpiece. This allows for complex processing path planning to be realized in a smaller space, improving the diversity and efficiency of processing.

[0040] Refer to Figure 2 and Figure 3In some embodiments of this utility model, the second drive assembly 210 includes a drive motor 211 and a lifting seat 212. The drive motor 211 connects to and drives the lifting seat 212 to move along the Y-axis. The first spindle 220 and the second spindle 230 are both mounted on the lifting seat 212. Through the cooperative use of the drive motor 211 and the lifting seat 212, the first spindle 220 and the second spindle 230 can move precisely along the Y-axis, improving machining accuracy. The lifting seat 212 is mounted on one side of the connecting seat 300, and the cutting tool 130 is mounted on the other side of the connecting seat 300 via a tool holder. Further, in some embodiments of this utility model, the second drive assembly 210 includes a speed-increasing transmission component 213 and a linear transmission component 214. The drive motor 211, the speed-increasing transmission component 213, the linear transmission component 214, and the lifting seat 212 are sequentially connected. The combined use of the speed-increasing transmission component 213 and the linear transmission component 214 makes the movement in the Y-axis direction smoother and more controllable. Furthermore, by adjusting the transmission ratio through the speed-increasing transmission component 213, the spindle's movement speed can be optimized, improving processing efficiency. Specifically, the speed-increasing transmission component 213 includes a first synchronous pulley 2131, a second synchronous pulley 2132, and a synchronous belt 2133. The first synchronous pulley 2131 and the second synchronous pulley 2132 are connected by the synchronous belt 2133, ensuring smooth and accurate transmission and reducing energy loss during power transmission. The first synchronous pulley 2131 is fixedly connected to the drive shaft of the drive motor 211, and the second synchronous pulley 2132 is connected to the input end of the linear transmission component 214. The pitch circle diameter of the first synchronous pulley 2131 is larger than that of the second synchronous pulley 2132. This increases the rotational speed of the second synchronous pulley 2132, thereby increasing the movement speed of the lifting plate. Additionally, the linear transmission component 214 includes a screw 2141 and a screw block 2142. The lifting seat 212 is slidably mounted on the worktable 120 along the Y-axis direction. For example, the lifting seat 212 is fixedly connected to a slider, and the connecting seat 300 is fixedly connected to a guide rail arranged in the Y-axis direction, with the slider slidably mounted on the guide rail. The middle part of the screw block 2142 is threadedly connected to the screw 2141, and the outer wall of the screw block 2142 is fixedly connected to the lifting seat 212. The second synchronous pulley 2132 is fixedly connected to the end of the screw 2141 to drive the screw 2141 to rotate and thus drive the lifting seat 212 to move linearly. It is easy to understand that the threaded transmission connection between the screw 2141 and the screw block 2142 is simple, reliable, easy to implement, and reduces maintenance costs. By driving the screw 2141 to rotate through the drive motor 211, and then driving the linear motion of the lifting seat 212, the conversion from rotation to linear motion is realized.

[0041] Refer to Figure 2 and Figure 3In some embodiments of this utility model, the lifting seat 212 is provided with a first clamping groove 2121 and a second clamping groove 2122. A first spindle 220 passes through the first clamping groove 2121, and a second spindle 230 passes through the second clamping groove 2122. The lifting seat 212 is threadedly connected with a first screw and a second screw. The first screw drives the first clamping groove 2121 to contract, thereby clamping the outer wall of the first spindle 220; the second screw drives the second clamping groove 2122 to contract, thereby clamping the outer wall of the second spindle 230. It is easily understood that the clamping mechanism of the first and second screws ensures the stable installation of the first spindle 220 and the second spindle 230 in the lifting seat 212, avoiding displacement caused by vibration during processing. Furthermore, the adjustable clamping groove size allows for fine-tuning according to different spindle dimensions, improving the adaptability of the equipment and the processing quality. In addition, after the first screw loosens the first clamping groove 2121, the first spindle 220 can adjust its position along the center line of the first clamping groove 2121; after the second screw loosens the second clamping groove 2122, the second spindle 230 can adjust its position along the center line of the second clamping groove 2122; thus, it can quickly adapt to the processing requirements of workpieces of various specifications.

[0042] In some embodiments of this utility model, such as Figure 1 As shown, a chip removal groove 101 is provided on the lower side of the worktable 120, which helps to remove chips generated during processing in a timely manner, avoiding chip accumulation that affects processing quality and equipment operation. Furthermore, an effective chip removal system can reduce maintenance workload, extend equipment lifespan, and improve overall processing efficiency.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
