Description

Technical Field

[0001] This invention relates to the field of milling and turning center technology, and in particular to a full-process milling and turning center for turning rollers. Background Technology

[0002] During the production process, the roller requires multiple processing steps, including milling at the ends of the roller. The roller needs to be fixed on the spindle of the lathe, which drives it to rotate. Then, milling is performed using the corresponding milling cutter on the turret. To improve the efficiency of milling, a milling center with a double turret is generally used to process the roller at the same time, thereby improving work efficiency.

[0003] However, in practical applications, some problems remain unresolved. The following are some common issues in a full-process milling center for turning rollers: During the milling process, the spindle is mainly mounted on the feed box, which is supported by slide rails. The feed box slides on the guide rails to facilitate the feeding of the roller. During the milling process, as the feed box drives the spindle to move in multiple directions, impurities generated during milling easily fall onto the slide rails. After prolonged use, the slide rails wear out and require maintenance or replacement. This necessitates removing the feed box, which requires disconnecting it from the drive structure, increasing maintenance difficulty and affecting the maintenance efficiency of the slide rails and feed box. Summary of the Invention

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, referring to Figures 1-5This is the first embodiment of the present invention, which provides a full-process milling and turning center for turning rollers. The full-process milling and turning center for turning rollers includes a base 1, a spindle feed box 2, a guide rail 3, a support structure 4, a locking structure 5, a shock absorber 6, and a drive motor 7. The base 1 is the base of the entire milling and turning center. The spindle feed box 2 is disposed above the base 1 and is used to mount the spindle and drive the roller to rotate. The guide rail 3 is disposed between the base 1 and the spindle feed box 2, and is embedded in the bottom side of the spindle feed box 2 and slidably connected to it, guiding the spindle feed box 2 to move along the base 1. The support structure 4 is disposed on the top of the base 1 and is used to provide support for the guide rail 3 and the spindle feed box 2, as well as to control the lifting and lowering of the guide rail 3. The locking structure 5 is disposed on the side of the base 1 and is used to lock the support structure 4 when the guide rail 3 supports the spindle feed box 2, and to slow down the retraction speed when the guide rail 3 retracts. The shock absorber 6 is used to absorb the vibration transmitted to the spindle feed box 2 and the support structure 4 during operation. The drive motor 7 is fixed to the side of the base 1, and the output end of the drive motor 7 is connected to the support structure 4 to control the unfolding of the support structure 4 and the movement of the spindle feed box 2.

[0034] When the guide rail 3 needs maintenance or replacement, the support structure 4 is lowered by the drive motor 7, so that the guide rail 3 can be quickly disengaged from the spindle feed box 2. There is no need to disassemble the complex connection between the spindle feed box 2 and the drive structure. This solves the problem of high maintenance difficulty and low efficiency caused by the need to remove the feed box and disconnect it from the drive structure after the slide rail is worn.

[0035] The base 1, spindle feed box 2, guide rail 3, and drive motor 7 are all existing technologies. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0036] Example 2, refer to Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the support structure 4 includes several support grooves 8 formed on the top sidewall of the base 1, with multiple support grooves 8 evenly distributed along the length of the guide rail 3. Several support blocks 9 are slidably connected within the support grooves 8, and the top of each support block 9 is fixedly connected to the bottom sidewall of the guide rail 3. A channel 10 is formed on the bottom sidewall of the support groove 8, and a main channel 11 is formed within the base 1 and communicates with the bottom of the channel 10. When hydraulic oil enters the main channel 11 and passes through the channel 10 to the bottom of the support groove 8, the hydraulic oil pushes the support blocks 9 upwards, thereby lifting the guide rail 3 so that it abuts against the concave surface of the bottom side of the spindle feed box 2.

[0038] Specifically, the support structure 4 also includes a main shaft 12 rotatably connected to the base 1, and the main shaft 12 is fixedly connected to the output end of the drive motor 7. A push groove 13 is formed on the inner side of the base 1 and communicates with the main channel 11. A push plate 14 is slidably connected to the push groove 13, and a rotating ring 15 is rotatably connected to the push plate 14 and sleeved on the main shaft 12. A spiral groove 16 is formed on the inner circumferential sidewall of the rotating ring 15, and a drive block 17 is fixedly connected to the main shaft 12, and the drive block 17 is slidably connected to the spiral groove 16. When the drive motor 7 drives the main shaft 12 to rotate, the drive block 17 slides relative to the rotating ring 15 within the spiral groove 16, pushing the rotating ring 15 to move axially, thereby driving the push plate 14 to move within the push groove 13, pressing the hydraulic oil in the push groove 13 into the main channel 11.

[0039] Specifically, a drive groove 18 is provided on the top of the base 1 and below the spindle feed box 2. A drive screw 19 is rotatably connected to the drive groove 18, and the spindle body 12 passes through the drive screw 19 and is rotatably connected to it. A limiting groove 20 is provided at the end edge of the drive screw 19, and a limiting block 21 is fixed to the end edge of the rotating ring 15. The main support block 22 is slidably connected to the drive groove 18 and threadedly connected to the drive screw 19. When the rotating ring 15 moves to the point where the limiting block 21 inserts into the limiting groove 20, the rotating ring 15 and the drive screw 19 are engaged. The rotation of the rotating ring 15 drives the drive screw 19 to rotate, thereby driving the main support block 22 to move along the drive groove 18. The spindle feed box 2 is connected to the main support block 22 by bolts, realizing the feed movement of the spindle feed box 2.

[0040] Example 3, referring to Figures 2-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0041] Specifically, the locking structure 5 includes a liquid storage tank 23 fixed to the side of the base 1. The liquid storage tank 23 is connected to the push groove 13 and contains damping fluid. The push plate 14 has an inclined groove 24 at one end near the liquid storage tank 23. The locking rod 25 is located at the top of the base 1 and inserted into the push groove 13. The bottom end of the locking rod 25 is in contact with the inclined side wall of the inclined groove 24. The push plate 14 moves away from the liquid storage tank 23 under the movement of the rotating ring 15. When the push plate 14 moves to the designated position, the locking rod 25 falls into the bottom of the inclined groove 24 under the action of gravity or spring, and abuts against the bottom side of the push plate 14 to lock it and prevent the push plate 14 from retracting under the gravity of the guide rail 3.

[0042] Additionally, a groove 26 is formed on the top side of the push groove 13, and the limiting block 27 is hinged within the groove 26. A limiting groove 28 is formed on the outer periphery of the rotating ring 15, and the end of the limiting block 27 is in contact with the inner wall of the limiting groove 28. A shallow groove 29 is formed on the outer periphery of the rotating ring 15 and communicates with the limiting groove 28. During the axial movement of the rotating ring 15, the limiting block 27 is always in contact with the side wall of the limiting groove 28 to prevent the rotating ring 15 from rotating due to the cooperation between the spiral groove 16 and the drive block 17; when the rotating ring 15 moves to the point where the limiting block 27 enters the shallow groove 29, the limiting block 27 loses its lateral restraint, allowing the rotating ring 15 to rotate with the main shaft 12.

[0043] The limiting block 27 is inclined, and the side of the limiting groove 28 that contacts the limiting block 27 is set at an acute angle. The inner wall of the shallow groove 29 is set in an arc shape. The acute angle setting creates a wedge effect for the limiting block 27 in the limiting groove 28, ensuring that the rotating ring 15 will not rotate before reaching the docking position; the arc shape setting allows the limiting block 27 to slide out smoothly after entering the shallow groove 29, facilitating the rotation of the rotating ring 15.

[0044] Example 4, refer to Figures 4 to 10 This is the fourth embodiment of the present invention, which is based on the first three embodiments.

[0045] Specifically, the damping component 6 includes a damping groove 30 formed within the base 1 and located on the side of the drive groove 18, filled with damping fluid. A slide groove 31 is formed on the inner wall of the drive groove 18, and a guide block 32 is slidably connected within the slide groove 31 and fixedly connected to the main support block 22. A guide rod 33 is fixed within the slide groove 31, passes through the guide block 32, and is slidably connected to it, with its end extending into the damping groove 30. When the main support block 22 vibrates during milling, the vibration is transmitted through the guide block 32 along the guide rod 33 to the damping fluid in the damping groove 30. The intermolecular friction of the damping fluid converts mechanical energy into heat energy, thereby absorbing the vibration.

[0046] A guide tube 34 is inserted into the side of the base 1, communicating with the damping groove 30, and the end of the guide tube 34 is tapered. A control tube 35 is slidably connected to the end of the guide tube 34, and a guide hole 36 is opened on the outer periphery of the control tube 35. The end of the control tube 35 passes through the damping groove 30 and is slidably connected to the inner wall of the damping groove 30. A thermal spring 37 is fixed to the inner wall of the damping groove 30, and the end of the thermal spring 37 is fixedly connected to the outer periphery of the control tube 35. When the temperature of the damping fluid rises, causing the viscosity to decrease, the thermal spring 37 expands due to heat, pushing the control tube 35 inward, so that the guide hole 36 enters the guide tube 34 from the tapered end and communicates with the guide tube 34. The coolant enters the control tube 35 through the guide tube 34 to cool the damping fluid and restore its viscosity and damping effect.

[0047] An auxiliary channel 38 is provided inside the base 1 and located on the side of the damping groove 30. A heat-conducting rod 39 is fixed inside the auxiliary channel 38 near the damping groove 30 to conduct heat from the damping fluid into the auxiliary channel 38. A temperature-sensitive spring 40 is fixed inside the auxiliary channel 38 near the damping groove 30, and a piston plate 41 is fixed to the end of the temperature-sensitive spring 40. The side of the piston plate 41 is in contact with the end of the heat-conducting rod 39. The auxiliary channel 38 is connected to the main channel 11. When the temperature of the damping fluid rises, the heat-conducting rod 39 conducts heat to the temperature-sensitive spring 40. The temperature-sensitive spring 40 extends due to heat, pushing the piston plate 41 to move and pressurize the hydraulic oil in the auxiliary channel 38 into the main channel 11. This increases the lifting force of the support block 9 on the guide rail 3, thereby improving the contact rigidity between the guide rail 3 and the spindle feed box 2 and reducing the damage of vibration to the connection structure.

[0048] Example 5, refer to Figures 2-8 This is the fifth embodiment of the present invention, which is based on the previous four embodiments.

[0049] Specifically, a sealing ring is provided at the connection between the bottom of the support groove 8 and the channel 10. The sealing ring is fitted around the outer periphery of the support block 9 to prevent hydraulic oil from leaking from the gap between the support groove 8 and the support block 9. The sealing ring is made of polyurethane or fluororubber, which is oil-resistant and wear-resistant.

[0050] At least two sealing rings are fitted on the outer periphery of the push plate 14. The sealing rings fit tightly against the inner wall of the push groove 13 to ensure that the chambers on both sides of the push plate 14 are isolated from each other when the push plate 14 slides in the push groove 13, thus preventing the hydraulic oil from mixing with the damping fluid. The top of the reservoir 23 is provided with an injection port and an exhaust valve. The injection port is used to replenish the damping fluid into the reservoir 23, and the exhaust valve is used to expel the air in the reservoir 23, ensuring that the damping fluid can smoothly enter and exit the reservoir 23 when the push plate 14 moves.

[0051] The space between the guide block 32 and the guide rod 33 is filled with grease to reduce the frictional resistance between them, enabling the vibration to be efficiently transmitted to the damping groove 30. The portion of the guide rod 33 extending into the damping groove 30 is designed with a porous structure to increase the contact area between the guide rod 33 and the damping fluid, thereby improving the absorption efficiency of vibration energy.

[0052] The auxiliary channel 38 is filled with thermally conductive silicone grease between the side of the piston plate 41 and the temperature-sensing spring 40 to improve the heat conduction efficiency between the heat-conducting rod 39 and the temperature-sensing spring 40, so that the temperature-sensing spring 40 can respond quickly to the temperature change of the damping fluid.

[0053] In the initial state of use, the guide rail 3 and the bottom of the spindle feed box 2 are separated. When needed, the drive motor 7 is started first. The drive motor 7 drives the spindle body 12 to rotate counterclockwise. The rotation of the spindle body 12 will drive the drive block 17 to rotate. The rotation of the drive block 17 causes it to slide relative to the spiral groove 16, thereby pushing the rotating ring 15 to move, so that the rotating ring 15 approaches the drive screw 19 until the limiting inclined block 21 on the rotating ring 15 is inserted into the corresponding limiting inclined groove 20. At this time, the rotating ring 15 and the drive screw 19 are in a docking state. The spindle body 12 and the drive screw 19 are rotatably connected. The rotation of the spindle can only drive the rotation of the drive block 17, which in turn drives the rotation of the rotating ring 15 in conjunction with the spiral groove 16.

[0054] During this period, the movement of the rotating ring 15 will drive the push plate 14 connected to it to move. The push groove 13, the main channel 11 and the channel 10 are all filled with hydraulic oil. When the push plate 14 slides in the push groove 13, it will drive the hydraulic oil into the main channel 11, and then let the hydraulic oil enter the channel 10 respectively, squeezing the corresponding support block 9, so that the support block 9 moves upward in the support groove 8, and finally drives the guide rail 3 to move upward, so that the guide rail 3 abuts against the bottom side wall of the spindle feed box 2. The bottom side of the spindle feed box 2 is concave and fits against the surface of the guide rail 3.

[0055] In addition, during the movement of the push plate 14, when the push plate 14 slides in the push groove 13, it will also draw out the damping fluid in the reservoir 23, allowing the damping fluid to enter the push groove 13. The side of the rotating ring 15 near the drive motor 7 is in a closed state to prevent the damping fluid from entering the rotating ring 15. At the same time, the push plate 14 is in a closed state in the push groove 13 to facilitate the drawing out of the damping fluid in the reservoir 23. Meanwhile, the inclined groove 24 on the push plate 14 gradually moves away from the reservoir 23, and the locking rod 25 will gradually descend. After the push plate 14 moves to the designated position, the locking rod 25 is inserted into the bottom side of the inclined groove 24 and abuts against the bottom side of the push plate 14, achieving the locking effect.

[0056] Furthermore, to prevent the rotating ring 15 from directly rotating with the main shaft due to the increased hydraulic pressure when it is pushed, the end of the limiting block 27 is inserted into the limiting groove 28 and abuts against each other when the rotating ring 15 is driven to move. At this time, the rotating ring 15 is limited, preventing it from rotating under the push of the driving block 17. After the limiting inclined block 21 is inserted into the position of the limiting inclined groove 20, the limiting block 27 reaches the position of the shallow groove 29. The shallow groove 29 is arc-shaped, and the end of the limiting block 27 is also arc-shaped. The limiting block 27 loses its abutment. When the main shaft rotates, the rotating ring 15 cannot continue to move. At this time, the rotating ring 15 will rotate with the main shaft. At the same time, the push plate 14 is limited, so the rotating ring 15 is also limited. The rotating ring 15 cannot move axially and will rotate with the main shaft during rotation, so as to drive the rotation of the drive screw 19.

[0057] When it is necessary to disassemble the spindle feed box 2, or to clean or maintain the guide rail 3, pull the locking rod 25 upwards. After the locking rod 25 is pulled out, the weight of the guide rail 3 pushes the hydraulic oil back to its original position, thereby pushing the push plate 14 to move. The damping fluid in the push groove 13 will be slowly pushed into the reservoir 23. When the push plate 14 moves, it will drive the rotating ring 15 to move. The rotating ring 15 is limited by the drive block 17. At this time, during the movement, it will rotate under the limitation of the drive block 17, thereby releasing the limiting inclined block 2. The docking between the guide rail 3 and the limiting groove 20 releases the support of the spindle feed box 2 from the guide rail 3. At this time, the spindle feed box 2 can be quickly disconnected from the guide rail 3. The spindle feed box 2 and the main support block 22 can be connected by bolts. At this time, the spindle feed box 2 can be quickly disassembled. After the guide rail 3 is separated from the spindle feed box 2, it can be cleaned, maintained or replaced. This saves maintenance time between the lathe guide rail 3 and the spindle feed box 2, improves maintenance efficiency, and reduces the difficulty of maintenance, cleaning and replacement.

[0058] In addition, a vibration guide block 32 is fixed to the side of the main support block 22. The vibration guide block 32 can slide within the slide groove 31, and a vibration guide rod 33 is fixedly connected within the slide groove 31. The vibration guide rod 33 is slidably connected to the vibration guide block 32, and the end of the vibration guide rod 33 extends into the damping groove 30. A damping fluid of appropriate viscosity is injected into the damping groove 30. The vibration generated during milling and turning is transmitted to the damping groove 30 through the cooperation of the vibration guide block 32 and the vibration guide rod 33. The damping fluid filling the damping groove 30 absorbs the vibration. Under high-frequency vibration, the intense friction between liquid molecules converts the mechanical kinetic energy generated by the vibration into heat energy. As the temperature rises, the viscosity of the damping decreases, affecting the damping effect. With the increase in temperature, the thermal spring 37 is stretched, causing the control block to be inserted into the guide tube 34. The inner diameter of the guide tube 34 is larger than the inner diameter of the pipe opening, so the guide hole 36 is exposed inside the guide tube 34. The coolant then enters the control tube 35, thereby reducing the temperature of the control tube 35 and dissipating heat from the damping fluid to ensure the damping effect during continuous operation. The outer end of the control tube 35 connects to the external pipeline and exchanges heat before circulating with the coolant input into the guide tube 34.

[0059] In addition, the increase in the temperature of the damping fluid will increase the temperature of the temperature-sensitive spring 40, which will then extend and exert a thrust on the piston plate 41. This will increase the force on the hydraulic oil in the auxiliary channel 38, thereby pushing the hydraulic oil into the main channel 11. This will increase the contact force between the guide rail 3 and the spindle feed box 2, increase the docking rigidity, and reduce damage from vibration.
