Description
Technical Field

[0002] Turning and milling is an advanced manufacturing technology that combines turning and milling on a single machine tool to achieve more efficient and high-precision processing results. The spindle rotation of existing turning and milling machine tools is usually driven by a single motor. During turning or milling, the spindle needs to have a higher speed, so that the cutting speed is faster and the processing accuracy is higher. This requires the motor that drives the spindle to rotate to have a higher speed. When the workpiece needs to process multiple holes or grooves with a certain angle on the surface, the spindle needs to stop rotating and then be driven by the motor to rotate a certain angle at a slower speed. Therefore, in order to meet these two requirements, the motor needs to switch between high speed and low speed. A single motor cannot meet the high speed and precise control of the rotation angle well, so the overall transmission structure of the spindle needs to be redesigned. Summary of the invention

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0017] like Figure 1-Figure 13As shown, a horizontal turning and milling compound machining machine tool includes a frame 2, a dividing chuck 9, a spindle 27, a turning assembly 4, a milling assembly 7 and a tool magazine 8.

A first power member 3 for driving the first sliding seat 63 to slide horizontally is arranged on the frame 2, and the second sliding seat 6 is installed on the first sliding seat 63. The first sliding seat 63 is provided with a second power member 5 for driving the second sliding seat 6 to slide along the inclination angle direction of the mounting bevel. The turning assembly 4 and the milling assembly 7 are arranged on the second sliding seat 6. The tool magazine 8 is located at the front side of the frame 2 and is used to replace the machining tool for the milling assembly 7. The spindle 27 is rotatably mounted on the frame 2.

The first driving member includes a servo motor 15, a first driving gear 12 and a first one-way transmission member 13. The first one-way transmission member 13 is fixed to the output shaft of the servo motor 15. The first driving gear 12 is rotatably mounted on the output shaft of the servo motor 15 and is connected to the first one-way transmission member 13. When the first one-way transmission member 13 remains stationary, the first driving gear 12 can only rotate in one direction. The second driving member includes a high-speed motor 23, a second driving gear 22 and a second one-way transmission member 21. The first one-way transmission member 13 and the second one-way transmission member 21 have the same structure. The second one-way transmission member 21 is fixed on the output shaft of the high-speed motor 23. The second driving gear 22 is rotatably mounted on the output shaft of the high-speed motor 23. When the second one-way transmission member 21 remains stationary, the second driving gear 22 can only rotate in one direction. The connecting member includes a first transmission shaft 14, a first driven gear 10, and a second transmission shaft 19, the second driven gear 16 and the third driving gear 11, the first transmission shaft 14 and the second transmission shaft 19 are both rotatably arranged in the frame 2, the first driven gear 10 and the third driving gear 11 are both fixed on the first transmission shaft 14, the second driven gear 16 is fixed on the second transmission shaft 19, the third driven gear 26 and the fourth driven gear 24 are fixedly mounted on the main shaft 27, the first driven gear 10 is meshed with the first driving gear 12, the second driven gear 16 is meshed with the second driving gear 22 and the fourth driven gear 24, and the third driving gear 11 is meshed with the third driven gear 26.
[0018] The first one-way transmission member 13 includes a baffle plate 29, a mounting ring 28, a driving plate 31, a transmission column 30 and an elastic fastening member 33. An annular groove 49 is provided on the first driving gear 12, and a bearing is provided between the first driving gear 12 and the output shaft of the servo motor 15. The mounting ring 28 and the driving plate 31 are arranged in the annular groove 49, and the diameter of the mounting ring 28 is smaller than the maximum diameter of the annular groove 49. The driving plate 31 is located on the inner side of the mounting ring 28. A plurality of through grooves 35 for mounting the transmission column 30 are provided on the mounting ring 28. Two elastic fastening members 33 are provided on the same transmission column 30. One end of the elastic fastening member 33 is rotatably connected to the transmission column 30, and the other end is fixedly connected to the driving plate 31. The outer side of the driving disk 31 is provided with a plurality of guide bevels 34 distributed in an array, the distances from the two ends of the guide bevels 34 to the center of the driving disk 31 are different, and the distance from the guide bevels 34 to the inner wall of the maximum diameter of the annular groove 49 is smaller than the diameter of the transmission column 30, and the elastic fastening member 33 exerts a force on the transmission column 30 to resist the guide bevels 34 and the inner wall of the annular groove 49, and an annular cover 32 for covering the driving disk 31 is provided on one side of the mounting ring 28, the driving disk 31, the annular cover 32 and the baffle plate 29 are fixedly connected by bolts and nuts, and the baffle plate 29 is fixed on the output shaft of the servo motor 15, and the driving column 30 maintains contact with the inner wall of the annular groove 49 and the guide bevels 34 under the action of the elastic fastening member 33. When the servo motor 15 or the high-speed motor 23 drives the driving disc 31 to rotate, the driving disc 31 rotates relative to the first driving gear 12 or the second driving gear 22, and the transmission column 30 moves toward the minimum distance position between the inner wall of the annular groove 49 and the guide inclined surface 34 and is stuck, so that the driving disc 31 relies on the transmission column 30 to drive the first driving gear 12 or the second driving gear 22 to rotate, so that the main shaft 27 can be driven to rotate under the drive of the connecting member, and when the high-speed motor 23 stops working, its output shaft is locked. When the main shaft 27 and the first transmission shaft 14 are driven by the servo motor 15, the second transmission shaft 19 and the second driven gear 16 are driven by the fourth driven gear 24. The second driving gear 22 rotates under the drive of the second driven gear 16. At this time, the second driving gear 22 drives the transmission column 30 to move in the direction of the compressed elastic fastening member 33 by relying on the friction force. In this way, the second driving gear 22 cannot transmit power to the driving disk 31 of the second one-way transmission member 21, so that no torque is generated on the output shaft of the high-speed motor 23, so as to achieve a protective effect. Similarly, when the servo motor 15 stops working, its output shaft will not be subjected to external force to generate torque. In this way, without adjusting the positions of the first driving gear 12 and the second driving gear 22, the servo motor 15 or the high-speed motor 23 can be controlled to work separately and drive the main shaft 27 to rotate.
[0019] The elastic fastening member 33 includes a movable sleeve 45, a first spring 44, a fixed block 39, an adjusting nut 38, a first limiting bolt 43 and a fastening bolt 40. The upper and lower ends of the transmission column 30 are provided with bosses 36. The movable sleeve 45 is sleeved on the bosses 36. The fixed block 39 is fixed to the driving disk 31 by the fastening bolt 40. The fixed block 39 and the movable sleeve 45 are respectively provided with a first convex rod 42 and a second convex rod 37. The second convex rod 37 is inserted into the first convex rod 42. The fixed block 39 is provided with a mounting hole 41. A first limiting bolt 43 is provided with a first convex rod 42. The first end of the first protruding rod 42 is located in the mounting hole 41, and the other end passes through the first protruding rod 42 and is fixedly connected to the second protruding rod 37. The outer side of the first protruding rod 42 is provided with a thread, and the adjusting nut 38 is threadedly connected to the first protruding rod 42. The first spring 44 is sleeved on the outer side of the first protruding rod 42 and the second protruding rod 37, and the two ends of the first spring 44 are respectively in conflict with the second protruding rod 37 and the adjusting nut 38. When installing the transmission column 30, first sleeve the mounting ring 28 on the outer side of the driving disk 31, and then turn the adjusting nut 38 on the first protruding rod 42 toward the direction of the fixing block 39, and then The first protruding rod 42 and the second protruding rod 37 are connected by the first limiting bolt 43, and the first spring 44 is sleeved on the outside of the first protruding rod 42 and the second protruding rod 37, and then the two second protruding rods 37 are sleeved on the boss 36 of the transmission column 30, and then the elastic fastening member 33 can be passed through the through groove 35 of the mounting ring 28, and the fixing block 39 can be fixed on the driving disk 31 by the fastening bolt 40, so that the assembly of the one-way transmission member can be completed, and because the first protruding rod 42 and the second protruding rod 37 are realized by the first limiting bolt 43 and the first spring 44 Telescopic, by adjusting the position of the adjusting nut 38, the elastic force of the first spring 44 on the transmission column 30 can be adjusted, so that the transmission column 30 can maintain resistance between the guide inclined surface 34 and the inner wall of the annular groove 49. When the driving disk 31 is driven by the servo motor 15 or the high-speed motor 23 to rotate, it can smoothly drive the first driving gear 12 or the second driving gear 22 to rotate. At the same time, the rotation of the transmission column 30 will not be affected when the first driving gear 12 or the second driving gear 22 rotates in the opposite direction, which can reduce the wear of a certain position of the transmission column 30.
[0020] The first driving gear 12 and the second driving gear 22 are provided with an inclined lubrication hole 50 and a sink 51, and a sealing ring is provided in the sink 51. After the first one-way transmission member 13, the second one-way transmission member 21, the first driving gear 12 and the second driving gear 22 are installed, the baffle plate 29 will generate pressure on the sealing ring, thereby ensuring the sealing between the baffle plate 29 and the first driving gear 12 or the second driving gear 22, so that the lubricating oil will not overflow.
[0021] The transmission ratios of the first driven gear 10 and the first driving gear 12, the third driven gear 26 and the third driving gear 11 are all greater than 1, and the transmission ratios of the second driven gear 16 and the second driving gear 22, the fourth driven gear 24 and the second driven gear 16 are all less than 1. By setting the transmission ratios of the driven gears and the driving gears, the high-speed motor 23 can drive the spindle 27 to rotate at a higher speed, and when the servo motor 15 rotates, the rotation angle of the spindle 27 can be more accurately controlled during the low-speed rotation process, which can better meet the needs of actual processing.
[0022] One end of the second transmission shaft 19 is provided with a detection component 1 for detecting its rotation angle. The detection component 1 includes a conductive sheet 18, a movable conductive rod 17, a second spring 20, a counter, a battery and a trigger switch. An insulating sheet 48 is provided between the conductive sheet 18 and the second driven gear 16, and the conductive sheet 18 includes an annular portion 47 and an extension portion 46. There are multiple extension portions 46 and they are distributed in an equiangular array. There are two movable conductive rods 17 and two second springs 20. The movable conductive rod 17 is slidably arranged on the frame 2. The second spring 20 is sleeved on the movable conductive rod 17 and exerts a resistance on the movable conductive rod 17 to contact the extension portion 46 or the insulating sheet 48 between two adjacent extension portions 46. The movable conductive rod 17, the battery, the counter and the trigger switch are coupled, and a closed circuit is formed when the two movable conductive rods 17 conflict with the extension portion 46. The counter is used to record the number of times the closed circuit is powered on or off. The trigger switch and the servo are connected. The servo motor 15 is coupled and used to receive the electrical signal of the servo motor 15 working. One end of the movable conductive rod 17 maintains a state of contacting the extension part 46 or the insulating sheet 48 under the action of the second spring 20. When the second transmission shaft 19 rotates driven by the servo motor 15, the insulating sheet 48 and the conductive sheet 18 keep rotating synchronously, and the servo motor 15 sends an electrical signal to control the closing of the trigger switch while working, so that the battery can smoothly supply power to the counter circuit. When the two movable conductive rods 17 contact the insulating sheet 48 at the same time, the counter is powered on, and when the two movable guide rods contact the conductive sheet 18, the counter is powered on. In this way, the number of times the power is on or off is recorded by the counter, and the rotation angle of the second transmission shaft 19 can be recorded. Then, the rotation angle of the main shaft 27 can be calculated according to the transmission ratio. In addition, the operation of the servo motor 15 is controlled by feedback based on the rotation angle of the main shaft 27, so as to achieve the purpose of accurately adjusting the angle.
[0023] A brake assembly 25 is provided at a position corresponding to the main shaft 27 on the frame 2, and the brake assembly 25 includes an iron core 54, an electromagnetic coil 52 and a brake sleeve 55. The iron core 54 is fixed in the frame 2, and the electromagnetic coil 52 is wound on the outside of the iron core 54. The brake sleeve 55 is slidably arranged on the main shaft 27. A plurality of limiting members are arranged between the brake sleeve 55 and the third driven gear 26, and the limiting members include a second limiting bolt 57 and a third spring 56. One end of the second limiting bolt 57 passes through the third driven gear 26 and is fixedly connected with the brake sleeve 55. The third spring 56 is sleeved on the outside of the second limiting bolt 57 and applies a force to the brake sleeve 55 to resist the third driven gear 26. The iron core 54 is provided with a limiting member that is in contact with the brake sleeve 55. The matched conical groove 53, when the electromagnetic coil 52 is energized, it will generate a magnetic field, and the iron core 54 will generate electromagnetic force to enhance the electromagnetic coil 52, and generate electromagnetic attraction to the brake sleeve 55, so that the brake sleeve 55 slides along the main shaft 27 toward the iron core 54. At this time, the third spring 56 is compressed until the brake sleeve 55 is matched with the conical groove 53, so that the iron core 54 and the brake sleeve 55 are adsorbed together. Since the iron core 54 is fixed to the frame 2, the main shaft 27 cannot continue to rotate, thereby achieving the purpose of braking. When the electromagnetic coil 52 is de-energized, its electromagnetic attraction disappears, and the brake sleeve 55 is reset under the action of the third spring 56, so that the brake sleeve 55 can continue to rotate synchronously with the main shaft 27.
[0024] The tool magazine 8 includes a mounting seat 58, a turret 61, a movable plate 60, a cylinder 59 and a stepper motor 62. The turret 61 is rotatably set in the mounting seat 58, and one end of the turret 61 is fixedly connected to the output shaft of the stepper motor 62. The movable plate 60 is slidably set in the open position of the mounting seat 58. The cylinder 59 is fixed on the mounting seat 58, and its piston is fixedly connected to the movable plate 60. The cylinder 59 can drive the movable plate 60 to slide on the mounting seat 58, so that the turret 61 is exposed to the outside, and the turret 61 is driven to rotate by the stepper motor 62, so that the milling cutter, drill bit or tap can be rotated out of the mounting seat 58, thereby the milling assembly 7 can be changed.
[0025] Working principle: When the workpiece is clamped on the indexing chuck 9, the first power member 3 and the second power member 5 respectively drive the first sliding seat 63 and the second sliding seat 6 to move, so that the turning assembly 4 and the milling assembly 7 are close to the workpiece. When the workpiece needs to be turned, the high-speed motor 23 drives the second one-way transmission member 21 to rotate, and the drive disk 31 is kept as Fig.10In the embodiment of the present invention, the third driving gear 11 is engaged with the third driven gear 26, and the first driven gear 10 is engaged with the first driving gear 12. In the embodiment of the present invention, the third driving gear 11 is engaged with the third driven gear 26, and the first driven gear 10 is engaged with the first driving gear 12. In the embodiment of the present invention, the third driving gear 11 is engaged with the third driven gear 26, and the first driven gear 10 is engaged with the first driving gear 12. Figure 2 The meshing transmission relationship in the first driving gear 12 also enables the first driving gear 12 to rotate in the direction A. However, because the direction of rotation of the first driving gear 12 will generate a force to compress the first spring 44 on the transmission column 30 in the first one-way transmission member 13, the transmission column 30 cannot maintain a state of being pressed against the inner wall of the annular groove 49 and the guide inclined surface 34. In this way, the power of the first driving gear 12 to rotate cannot be transmitted to the output shaft of the servo motor 15 through the transmission column 30, which effectively protects the servo motor 15 whose output shaft is locked, and the rotation of the first driving gear 12 can be kept smooth without jamming. Similarly, when the spindle 27 is required to drive the workpiece to rotate a certain angle and use a milling cutter or a drill to process multiple holes, the first driving gear 12 is driven by the spindle 27 to rotate the workpiece by a certain angle. The servo motor 15 drives the first one-way transmission member 13 to rotate, and the driving disk 31 can drive the first driving gear 12 to rotate synchronously in the direction A, and rely on the first transmission shaft 14, the first driven gear 10, the third driving gear 11 and the third driven gear 26 to drive the main shaft 27 to rotate, and the meshing transmission of the fourth driven gear 24 and the second driven gear 16 can drive the second driving gear 22 to rotate in the direction A. At this time, when the output shaft of the high-speed motor 23 is locked, the second driving gear 22 cannot transmit power to the driving disk 31 through the transmission column 30, which can protect the high-speed motor 23. When the high-speed motor 23 and the servo motor 15 work alone, the above effect can be achieved without adjusting the positions of the first driving gear 12 and the second driving gear 22.
[0026] In this embodiment, the indexing chuck 9 can drive the workpiece to rotate, so that different end faces of the workpiece can face the turning component 4 and the milling component 7, so that all processing steps can be completed in one clamping, thereby greatly improving the processing efficiency of the workpiece.
