[0001] The present invention relates to the technical field of numerical control machine tool design, in particular to a compound lathe. Background Art

[0002] CNC lathes, also known as CNC lathes (computer numerically controlled lathes), are currently the most widely used and widely used type of CNC machine tool in China, accounting for approximately 25% of all CNC machine tools. CNC machine tools are mechatronic products that integrate multiple technologies, including mechanical, electrical, hydraulic, pneumatic, microelectronic, and information technologies. They are machine tools in mechanical manufacturing equipment, offering advantages such as high precision, high efficiency, high automation, and high flexibility. The technological level of CNC machine tools and their percentage in metal cutting machine tool production and ownership are important indicators of a country's national economic development and overall industrial manufacturing level. CNC lathes, as one of the main types of CNC machine tools, occupy a very important position among CNC machine tools. For decades, they have been widely recognized and rapidly developed worldwide.

[0003] Existing CNC lathes cut chips in the X and Y directions of workpieces, primarily used for machining shafts and rod-shaped workpieces. However, when drilling holes or milling different patterns on the workpiece surface, the workpiece processed on the CNC lathe must be placed on another CNC milling machine for milling and drilling. This method requires multiple CNC machine tools, increases the number of machining steps, and increases the human resources required to operate the equipment, resulting in higher machining costs. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a compound lathe for solving the technical problem raised in the background art that the lathe in the prior art cannot perform drilling and milling on the workpiece at the same time.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A compound lathe comprises a base, a clamping head for clamping a workpiece is fixedly provided on the upper end of the base, a tool holder is also provided on the upper end of the base for sliding horizontally along the clamping head and for mounting a turning tool and cutting the workpiece on the clamping head, a mounting bracket with a movable hole in the middle is also slidably provided on the upper end of the base, a first driving component is also fixed on the side wall of the base to drive the mounting bracket to slide on the base along the sliding direction of the turning tool holder, a mounting sleeve with two ends passing through is also slidably provided in the movable hole of the mounting bracket, a second driving component is also fixed on the top of the mounting bracket to drive the mounting sleeve to slide vertically up and down in the movable hole, and a connecting sleeve is slidably penetrated in the mounting sleeve The block is further provided with a third driving assembly that drives the connecting block to slide horizontally in the mounting sleeve along a direction perpendicular to the sliding direction of the lathe tool holder. The connecting block is also provided with a rotating hole with two ends passing therethrough in the direction of the horizontal sliding of the mounting sleeve, and a horizontal rotating shaft is also slidably passed through the rotating hole. The end of the connecting block close to the clamping head is also provided with a milling cutter holder for clamping the milling cutter and milling the workpiece on the clamping head. The milling cutter holder is also fixed with a driving motor that rotates the milling cutter on the milling cutter holder, and the milling cutter holder is fixedly connected to one end of the rotating shaft. The end of the connecting block away from the clamping head is also provided with a fourth driving assembly that drives the rotating shaft to rotate.

[0007] Working principle:

[0008] The invention relates to a compound lathe, which mainly has the functions of cutting chips, punching holes and milling surfaces of workpieces.

[0009] When in use, first install the workpiece to be processed on the clamping head, then operate the clamping head and make it drive the workpiece to rotate, and then move the tool holder to make the tool on the tool holder cut the workpiece. When the workpiece reaches the required size, stop cutting and stop the clamping head from rotating.

[0010] When it is necessary to drill holes or mill the surface of the workpiece, it is only necessary to load the milling cutter into the milling cutter holder and turn on the drive motor so that the drive motor drives the milling cutter to rotate, and then the mounting frame is driven to start moving by operating the first drive assembly. Because the milling cutter holder is installed on the rotating shaft in the connecting block, and the connecting block is installed in the mounting frame, when the mounting frame starts to move, the milling cutter will be driven to move. The second drive assembly is further turned on and the mounting sleeve is driven to slide vertically in the movable hole on the mounting frame, and the connecting block and the milling cutter are moved at the same time. The third drive assembly is further turned on, and the third drive assembly drives the connecting block to slide horizontally relative to the mounting sleeve, and the milling cutter holder and the milling cutter are moved horizontally at the same time, move to the position where the milling cutter contacts the workpiece, and start milling and drilling the workpiece.

[0011] When the angle of the milling cutter holder relative to the workpiece needs to be changed, it is only necessary to operate the fourth driving assembly to drive the rotating shaft to rotate in the rotating hole, thereby driving the milling cutter to rotate.

[0012] Beneficial effects obtained:

[0013] First, a first driving assembly is provided, which can effectively drive the position of the mounting frame on the base by operating the first driving assembly, and drive the milling cutter to adjust the position between the milling cutter and the workpiece.

[0014] Second, a second drive assembly and a third drive assembly are provided, which can effectively drive the mounting sleeve to slide vertically in the movable hole and the connecting rod to slide horizontally in the mounting sleeve by operating the second drive assembly and the third drive assembly respectively, thereby further adjusting the position between the milling cutter and the workpiece.

[0015] Third, a fourth drive assembly is provided, which can effectively drive the rotating shaft in the connecting block to rotate by operating the fourth drive assembly, further adjusting the angle between the milling cutter and the workpiece, so that the milling cutter can perform milling processing on different surfaces of the workpiece.

[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0025] Example:

[0026] Reference Figures 1 to 7 The present invention is a compound lathe, comprising a base 1, a clamping head 2 for clamping a workpiece fixedly provided on the upper end of the base 1, a tool holder 3 for sliding horizontally along the clamping head 2 and for mounting a turning tool and cutting the workpiece on the clamping head 2, and a mounting frame 4 with a movable hole 5 in the middle part also slidingly provided on the upper end of the base 1. Figure 4As shown, a first driving assembly for driving the mounting frame 4 to slide on the base 1 along the sliding direction of the tool holder 3 is also fixedly provided on the side wall of the base 1. The first driving assembly includes a first motor 12, a first screw rod 13, a first threaded sleeve 14, a first gear 15, a second gear 16 and a first belt 17 with a gear groove inside. The first motor 12 is fixedly mounted on the side wall of the base 1, and the first gear 15 is fixedly mounted on the output end of the first motor 12. The first screw rod 13 is rotated and horizontally mounted on the base 1. The end of the first screw rod 13 extends out of the base 1, and the second gear 16 is fixedly mounted on the end of the first screw rod 13 extending out of the base 1. The first belt 17 is sleeved between the first gear 15 and the second gear 16, and is respectively engaged with the first gear 15 and the second gear 16. The first threaded sleeve 14 is threadedly connected to the first screw rod 13, and the top of the first threaded sleeve 14 is fixedly connected to the bottom of the mounting frame 4. This arrangement effectively activates the first motor 12 and drives the first gear 15 to rotate. The first belt 17 on the first gear 15 further drives the second gear 16 to rotate. The second gear 16 then drives the first screw 13 to rotate, causing the first threaded sleeve 14 and the mounting bracket 4 fixedly connected to the first threaded sleeve 14 to move on the first screw 13. The base 1 is also provided with a plurality of first rails 18 parallel to the first screw 13. Several first sliders 19 are slidably mounted on each of the first rails 18. The tops of the several first sliders 19 are fixedly connected to the bottom of the mounting bracket 4. Because the first rails 18 are provided on the base 1, and the mounting bracket 4 is slidably mounted above the first rails 18 via the first sliders 19, this arrangement effectively increases the stability of the mounting bracket 4 during movement and improves the accuracy of the workpiece milling process performed by the present invention.

[0027] like Figure 1 and Figure 2As shown, a mounting sleeve 6 with two ends passing through is also slidably provided in the moving hole 5 of the mounting frame 4, and a second driving assembly that drives the mounting sleeve 6 to slide vertically up and down in the moving hole 5 is also fixed on the top of the mounting frame 4. The second driving assembly includes a second motor 20, a second screw rod 21, a third gear 22, a fourth gear 23 and a second belt 24 with a gear groove inside. The second motor 20 is fixedly mounted on the side wall of the mounting frame 4, and the third gear 22 is fixedly mounted on the output end of the second motor 20. One end of the second screw rod 21 is rotatably mounted on the side wall of the moving hole 5, and the other end of the second screw rod 21 extends vertically upward, passes through the other end of the moving hole 5 and extends to the outside of the mounting frame 4. The mounting sleeve 6 is threadedly connected to the second screw rod 21, and the fourth gear 23 is fixedly mounted on the end of the second screw rod 21 extending out of the mounting frame 4. The second belt 24 is sleeved between the third gear 22 and the fourth gear 23, and meshes with the third gear 22 and the fourth gear 23 respectively. This arrangement can effectively start the second motor 20 and drive the third gear 22 to rotate, further drive the fourth gear 23 to rotate through the second belt 24 on the third gear 22, and the fourth gear 23 drives the second screw rod 21 to rotate, and makes the mounting sleeve 6 threadedly connected to the second screw rod 21 on the second screw rod 21 slide vertically in the movable hole 5.

[0028] like Figure 2 、 Figure 3 and Figure 7As shown, a connecting block 7 is slidably penetrated in the mounting sleeve 6, and the connecting block 7 is also provided with a third drive assembly that drives the connecting block 7 to slide horizontally in the mounting sleeve 6 along a sliding direction perpendicular to the tool holder 3. The third drive assembly includes a third motor 25, a third screw rod 26, a second threaded sleeve 27, a fifth gear 28, a sixth gear 29 and a third belt 30 with a gear groove inside. The third motor 25 is fixedly mounted on the top of the connecting block 7 away from the milling cutter head 10, and the fifth gear 28 is fixedly mounted on the output end of the third motor 25. A sliding groove 31 is further provided on the side wall of the connecting block 7 in the sliding direction of the mounting sleeve 6. One end of the third screw rod 26 is rotatably mounted on the side wall of the sliding groove 31 close to the milling cutter head 10, and the other end of the third screw rod 26 moves toward the sliding groove 31 away from the milling cutter head 10. The sixth gear 29 is fixedly mounted on the end of the third screw rod 26 extending out of the connecting block 7. The third belt 30 is disposed between the fifth gear 28 and the sixth gear 29 and meshes with the fifth gear 28 and the sixth gear 29, respectively. The second threaded sleeve 27 is threadedly connected to the side wall of the third screw rod 26. The side of the second threaded sleeve 27 away from the bottom of the sliding groove 31 is fixedly connected to the side wall of the mounting sleeve 6. This arrangement effectively enables the third motor 25 to turn the fifth gear 28, which in turn is driven by the third belt 30 on the fifth gear 28 to rotate. The sixth gear 29 then drives the third screw rod 26 in the sliding groove 31 of the connecting block 7 to rotate. Because the second threaded sleeve 27 is threadedly mounted on the third screw rod 26 and fixedly connected to the side wall of the mounting sleeve 6, when the third screw rod 26 rotates, the connecting block 7 slides laterally within the mounting sleeve 6 due to the rotation of the third screw rod 26. A plurality of second rails 32 are fixedly mounted on the sidewalls of the connecting block 7. A plurality of second sliders 33 are slidably mounted on each of the second rails 32. The ends of the second sliders 33, which are distal to the second rails 32, are fixedly connected to the sidewalls of the mounting sleeve 6. This arrangement effectively increases the stability of the connecting block 7 during movement and further improves the accuracy of the milling process for workpieces.

[0029] like Figure 1 、 Figure 2 and Figure 6As shown, the connecting block 7 is provided with a rotating hole 8 passing through both ends along the horizontal sliding direction of the mounting sleeve 6, and a horizontal rotating shaft 9 is also slidably penetrated in the rotating hole 8. The connecting block 7 is also provided with a milling cutter holder 10 at one end close to the clamping head 2 for clamping the milling cutter and milling the workpiece on the clamping head 2. A driving motor 11 is also fixed on the milling cutter holder 10 to rotate the milling cutter on the milling cutter holder 10, and the milling cutter holder 10 is fixedly connected to one end of the rotating shaft 9. The end of the connecting block 7 away from the clamping head 2 is also provided with a fourth driving assembly for driving the rotating shaft 9 to rotate. The fourth driving assembly includes a fourth motor 34, a seventh gear 35, an eighth gear 36, a worm 37, a worm wheel 38 and a fourth belt 39 with a gear groove inside. A support frame 40 is also fixed to the top of the end of the connecting block 7 away from the milling cutter holder 10. The fourth motor 34 is fixedly mounted on the side wall of the support frame 40, and the seventh gear 35 is fixedly mounted on the output end of the fourth motor 34. One end of the worm 37 is rotatably mounted on the support frame 40, and the other end of the worm 37 horizontally passes through the support frame 40 and extends outward from the support frame 40. The eighth gear 36 is fixedly mounted on the end of the worm 37 extending from the support frame 40. The fourth belt 39 is sleeved between the seventh gear 35 and the eighth gear 36 and meshes with the seventh gear 35 and the eighth gear 36 respectively. The rotating shaft 9 extends out of the rotating hole 8 at the end away from the milling cutter head 10. The worm gear 38 is fixedly mounted on the end of the rotating shaft 9 extending out of the rotating hole 8 and meshes with the worm 37. This arrangement can effectively drive the seventh gear 35 to rotate through the fourth motor 34, and the eighth gear 36 to rotate through the fourth belt 39, further driving the worm 37 and driving the worm gear 38 to rotate. When the worm gear 38 rotates, it can drive the rotating shaft 9 and the milling cutter head 10 connected to the end of the rotating shaft 9 to rotate. Because the worm gear 38 is installed behind the rotating shaft 9, it can effectively improve the stability of the milling cutter during operation. A wire hole 41 is also provided in the middle of the rotating shaft 9, so that the wires and cables connected to the milling cutter frame 10 can pass through it conveniently, so that the milling cutter frame 10 remains simple.

[0030] like Figure 1 and Figure 3As shown, a fifth motor 42 is provided on the side wall of the base 1 below the clamping head 2. A ninth gear 43 is provided at the output end of the fifth motor 42. A fourth screw rod 44 is rotatably mounted on the base 1, parallel to and horizontal to the axis of the clamping head 2. One end of the fourth screw rod 44 extends out of the base 1, and a tenth gear 45 is fixedly mounted on the end of the fourth screw rod 44 extending out of the base 1. A fifth belt 46 with a gear groove therein is sleeved between the ninth gear 43 and the tenth gear 45. The tool holder 3 is threadedly connected to the fourth screw rod 44. This arrangement effectively enables the tool holder 3 to be moved on the base 1 by operating the fifth motor 42 to rotate the ninth gear 43, thereby driving the tenth gear 45 and the fourth screw rod 44 to rotate via the fifth belt 46.

[0031] When in use, first mount the workpiece to be processed on the clamping head 2, then operate the clamping head 2 and make the clamping head 2 drive the workpiece to rotate, and then move the tool holder 3 so that the tool on the tool holder 3 cuts the workpiece. When the workpiece reaches the required size, stop cutting and stop the clamping head 2 from rotating. When it is necessary to drill and mill the workpiece, it is only necessary to load the milling cutter into the milling cutter holder 10 and turn on the drive motor 11 so that the drive motor 11 drives the milling cutter to rotate, and then the first motor 12 is operated to drive the first gear 15 to rotate, and further the first belt 17 on the first gear 15 drives the second gear 16 to rotate, and the second gear 16 drives the first screw rod 13 to rotate, so that the first threaded sleeve 14 and the mounting frame 4 fixedly connected to the first threaded sleeve 14 move on the first screw rod 13. When the mounting frame 4 starts to move, because the milling cutter holder 10 is mounted on the rotating shaft 9 in the connecting block 7, and the connecting block 7 is mounted in the mounting frame 4, when the mounting frame 4 starts to move, the milling cutter will be driven to move, and the second motor 20 is further turned on to drive the third gear 22 to rotate, and further the second belt 24 on the third gear 22 drives the fourth gear 23 to rotate, and the fourth gear 23 drives the second screw rod 21 to rotate, and the mounting sleeve 6 on the second screw rod 21 that is threadedly connected to the second screw rod 21 moves in the moving hole 5. The third motor 25 is turned on and the fifth gear 28 is driven to rotate, and the sixth gear 29 is driven to rotate through the third belt 30 on the fifth gear 28. The sixth gear 29 drives the third screw rod 26 on the connecting block 7 and in the sliding groove 31 to rotate. Because the second threaded sleeve 27 is threadedly sleeved on the third screw rod 26, and the second threaded sleeve 27 is fixedly connected to the side wall of the mounting sleeve 6, when the third screw rod 26 rotates, the connecting block 7 will slide horizontally in the mounting sleeve 6 through the rotation of the third screw rod 26, and the milling cutter holder 10 and the milling cutter are moved horizontally at the same time. When it moves to the position where the milling cutter contacts the workpiece, the milling surface of the workpiece begins to be drilled. When it is necessary to change the angle of the milling cutter holder 10 relative to the workpiece, it is only necessary to operate the fourth motor 34 to drive the seventh gear 35 to rotate, and drive the eighth gear 36 to rotate through the fourth belt 39, further drive the worm 37 and drive the worm wheel 38 to rotate. When the worm wheel 38 rotates, it can drive the rotating shaft 9 and the milling cutter holder 10 and the milling cutter connected to the end of the rotating shaft 9 to rotate, and mill the workpiece from different angles.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
