Description

Technical Field

[0001] This invention belongs to the field of CNC machine tool technology, specifically relating to a power tool post for a milling and turning composite lathe. Background Technology

[0002] Milling-turning machining centers, as important representatives of modern high-precision and high-efficiency CNC machine tools, integrate multiple machining functions such as turning, milling, and drilling, and are widely used in high-end manufacturing fields such as aerospace, precision molds, and medical devices. In this type of equipment, the power tool post is one of the core components for realizing multi-process composite machining; its structural stability, positioning accuracy, and dynamic response performance directly affect the overall machining quality and efficiency.

[0003] Traditional milling and turning lathes typically use a lead screw-nut pair with linear guides to adjust the turret's position in the Y-axis direction (such as the centrally located Y-axis power turret in application number CN202110288978.2). However, in actual cutting processes, especially under heavy load or intermittent cutting conditions, the cutting force is easily transmitted to the lifting mechanism through the turret, generating a large radial load on the lead screw system, leading to lead screw bending deformation, servo motor overload, and even a decrease in positioning accuracy.

[0004] Furthermore, during frequent lifting and lowering of the power tool turret, the relative motion between the slider and the guide rail relies on rolling elements (such as rollers or balls) to achieve low-friction guidance (e.g., a CNC power tool turret with application number CN202511569005.0). To ensure long-term operational reliability, effective lubrication of the rolling pairs is essential. Traditional lubrication methods often employ external centralized oil supply systems, injecting oil into the guide rails at regular intervals and in measured quantities. However, this method suffers from problems such as untimely lubrication, difficulty in accurately controlling the oil quantity, and the potential for oil splashing and waste, as well as environmental pollution. More importantly, after the tool turret is positioned and locked, the lubrication system often stops working. When movement resumes, the rolling pair surfaces may already be in a state of dry friction or boundary lubrication, exacerbating wear and affecting the smoothness of movement. Summary of the Invention

[0005] In view of this, the purpose of this invention is to propose a power tool turret for a milling and turning lathe, which achieves low resistance in the movement of the milling and turning turret, high rigidity in locking, and integrates an automatic lubrication and oil recovery circulation system.

[0006] The specific technical solution adopted by this invention is as follows:

[0007] A power tool post for a milling and turning lathe includes a base, a lifting platform, a power turret, a tool head, and a drive mechanism for moving the lifting platform. It also includes a U-shaped seat on the lifting platform, on which two sliders are fixedly connected. Rollers are rotatably connected to both sides of the sliders in an array. A cavity is opened in the middle of the slider and a first piston plate is slidably connected thereto. The first piston plate divides the cavity into a first chamber and a second chamber. A brake pad is also provided on one side of the slider.

[0008] The slide rail is fixedly mounted on the machine base;

[0009] The drive unit is disposed on the U-shaped seat and the slider, and is used to drive the first piston plate and the brake pad to move;

[0010] The lubrication mechanism includes an oil delivery channel formed on the slider and an oil supply section communicating with the first chamber.

[0011] The recycling mechanism includes a recycling section and a return section disposed at the lower end of the slider, for recycling the lubricating fluid after use;

[0012] When the drive mechanism moves the lifting platform along the slide rail, the brake pads disengage from the slide rail; when the movement ends, the drive unit activates, driving the brake pads to contact the slide rail for braking, and drives the first piston plate to move within the cavity. When the first piston plate returns, it pressurizes the lubricating fluid in the second chamber to the surface of the rotating roller through the oil delivery channel.

[0013] In a preferred embodiment, the roller is hollow and has micropores evenly distributed on it.

[0014] In a preferred embodiment, a rack is fixedly embedded in the slide rail.

[0015] In a preferred embodiment, the drive mechanism includes a lead screw, which is rotatably connected to a machine base via bearings. A driven wheel is fixedly mounted on the upper end of the lead screw, and a servo motor is fixedly mounted on the machine base. A drive wheel is fixedly mounted on the output shaft of the servo motor.

[0016] In a preferred embodiment, a nut block is fixedly installed on the lifting platform, and the nut block is threadedly connected to the lead screw.

[0017] In a preferred embodiment, the driving unit includes a pressure chamber, which is located on a U-shaped seat. The upper end of the pressure chamber is connected to a filling pipe. A piston chamber is provided on one side of the pressure chamber. A second piston plate is slidably connected inside the piston chamber. A first piston rod is fixedly connected to one side of the second piston plate and extends to the outside of the slider. The first piston rod is fixedly connected to the first piston plate and a brake pad. A compression spring is fixedly connected between the second piston plate and the piston chamber. A trapezoidal plate is fixedly connected to one side of the first piston plate.

[0018] In a preferred embodiment, the oil delivery channel includes an oil storage tank, which is provided on the slider and located at the end of the rotating shaft of the roller. The slider is also provided with an oil inlet groove and a diversion pipe, wherein the oil inlet groove is connected to the second chamber, and the two ends of the diversion pipe are respectively connected to the oil inlet groove and the oil storage tank.

[0019] In a preferred embodiment, the oil supply unit includes an oil storage box, which is fixedly connected to the upper end of the slider, and an oil delivery pipe is connected between the oil storage box and the first chamber.

[0020] In a preferred embodiment, the recycling section includes a collection trough located at the lower end of the slider. A rotating rod is rotatably connected to the collection trough via a bearing. A water-absorbing roller is mounted on the rotating rod. A squeezing rod is also fixedly connected to the collection trough. One end of the rotating rod extends to the outside of the slider and is fitted with a pinion gear.

[0021] In a preferred embodiment, the reflux section includes a collection box, which is fixedly connected to a collection trough. The upper end of the collection box has through slots arranged in a ring. A T-shaped rod is piston-type inserted between the collection trough and the second chamber. The T-shaped end of the T-shaped rod extends into the interior of the collection box and is slidably connected to the collection box. The upper end of the T-shaped rod has a through hole. A fixing ring is fixedly fitted on the outer wall of the T-shaped rod. A spring is fixedly connected between the fixing ring and the collection box.

[0022] The technical effects achieved by this invention are as follows:

[0023] This invention achieves optimal performance balance of the power tool turret in both moving and stationary states through the coordinated design of the drive unit and brake pads. During movement, the brake pads disengage from the slide rail, and the slider relies on the rotating rollers to roll against the slide rail, greatly reducing frictional resistance and making the movement of the lifting platform smoother and more efficient. When machining begins, the drive unit activates, using pneumatic or hydraulic pressure to push the brake pads into close contact with the slide rail, generating braking force and maintaining the turret's extremely high static rigidity. This mechanism reduces the load on the leadscrew and nut block, extending the life of transmission components. This effect not only improves the machine tool's dynamic response speed but also resists the impact of heavy cutting forces through rigid locking, significantly improving overall reliability and safety.

[0024] The lubrication and recovery mechanisms of this invention form a closed-loop circulation system, realizing automatic supply and recycling of lubricating oil, reducing manual intervention and resource waste. During the release of the brake, the drive unit drives the first piston plate to move, pressing the lubricating oil in the second chamber through the oil delivery channel to the surface of the rotating roller, forming a uniform oil film and reducing movement resistance. Simultaneously, the recovery mechanism absorbs residual oil on the guide rail through the suction roller, and after being extruded by the extrusion rod, it flows back to the second chamber through the collection box and T-shaped rod, completing the circulation. This process not only keeps the guide rail clean and prevents oil contamination of the machine tool, but also filters impurities through the filter screen and recycles them, improving oil utilization rate.

[0025] This invention features a compact structure and a high degree of automation, enhancing the intelligence level and overall performance stability of machine tools. The entire system integrates four major functions—drive, lock, lubrication, and recovery—within a compact space within the slide block and U-shaped base. Controlled uniformly by pneumatic or hydraulic pressure, it offers rapid response and coordinated movements. This highly integrated automated design significantly reduces maintenance frequency and costs. Traditional machine tools require periodic manual lubrication and cleaning, while this invention extends component lifespan (e.g., reducing wear on rollers and slideways) through an automated system, aligning with green manufacturing principles and reducing lubricant consumption and environmental pollution.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0052] Please see the appendix Figures 1 to 7 As shown, this embodiment provides a power tool post for a milling and turning lathe, including a base 11, a lifting platform 12, a power turret 13, a tool head 14, and a drive mechanism 15 for driving the lifting platform 12 to move. It also includes a U-shaped seat 2 on the lifting platform 12, with two sliders 21 fixedly connected to the U-shaped seat 2. Rollers 22 are rotatably connected to both sides of the sliders 21 in an array. A cavity is opened in the middle of the sliders 21, and a first piston plate 23 is slidably connected thereto. The first piston plate 23 divides the cavity into a first chamber 24 and a second chamber 25. A brake pad 26 is also provided on one side of the sliders 21. The rollers 22 are hollow and have micro-holes (not shown in the figure) evenly distributed on them.

[0053] Slide rail 3 is fixedly installed on the machine base 11, and a rack 31 is fixedly embedded in slide rail 3;

[0054] Drive unit 4 is disposed on U-shaped seat 2 and slider 21, and is used to drive the first piston plate 23 and brake pad 26 to move.

[0055] The lubrication mechanism 5 includes an oil delivery channel 51 opened on the slider 21 and an oil supply section 52 communicating with the first chamber 24.

[0056] The recycling mechanism 6 includes a recycling section 61 and a return section 62 disposed at the lower end of the slider 21, for recycling the lubricating fluid after use.

[0057] When the drive mechanism 15 drives the lifting platform 12 to move along the slide rail 3, the brake pad 26 disengages from the slide rail 3; when the movement ends, the drive unit 4 is activated, driving the brake pad 26 to contact the slide rail 3 for braking, and driving the first piston plate 23 to move in the cavity. When the first piston plate 23 returns, it presses the lubricating fluid in the second chamber 25 through the oil delivery channel 51 to the surface of the roller 22.

[0058] In this embodiment, the first piston plate 23 moves within the cavity of the slider 21, dividing the cavity into a first chamber 24 and a second chamber 25. The first piston plate 23 is designed with oil holes (not shown in the figure) to allow oil to flow slowly between the two chambers, ensuring oil pressure balance.

[0059] Secondly, please refer to it again. Figures 1 to 3 The drive mechanism 15 includes a lead screw 151, which is rotatably connected to the base 11 via bearings. A driven wheel 152 is fixedly installed at the upper end of the lead screw 151. A servo motor 153 is fixedly installed on the base 11. A drive wheel 154 is fixedly installed on the output shaft of the servo motor 153. A nut block is fixedly installed on the lifting platform 12, and the nut block is threadedly connected to the lead screw 151.

[0060] In this embodiment, when it is necessary to adjust the position of the power turret 13 along the Y-axis, the servo motor 153 is activated. The output shaft of the servo motor 153 drives the drive wheel 154 to rotate, which in turn drives the driven wheel 152 via a transmission belt, thereby driving the lead screw 151 to rotate. The lead screw 151 is threadedly connected to a nut block fixedly mounted on the lifting platform 12, thus converting the rotational motion of the lead screw 151 into linear movement of the lifting platform 12 in the vertical direction, achieving precise adjustment of the position of the power turret 13. During this movement, the U-shaped seat 2 fixed on the lifting platform 12 and its slider 21 slide along the slide rail 3 fixedly mounted on the base 11, playing a guiding and supporting role. At this time, the rotating rollers 22 arrayed on both sides of the slider 21 contact and roll with the slide rail 3, forming a low-friction rolling pair, which greatly reduces the moving resistance. At the same time, the brake pad 26 is disengaged from the slide rail 3, and no braking friction is generated, ensuring smooth and efficient movement.

[0061] Secondly, please refer to the following as well. Figure 9 and Figure 11The drive unit 4 includes a pressure chamber 41, which is located on the U-shaped seat 2. The upper end of the pressure chamber 41 is connected to a filling pipe 42. A piston chamber 43 is provided on one side of the pressure chamber 41. A second piston plate 45 is slidably connected in the piston chamber 43. A first piston rod 44 is fixedly connected to one side of the second piston plate 45 and extends through to the outside of the slider 21. The first piston rod 44 is fixedly connected to the first piston plate 23 and the brake pad 26. A compression spring 46 is fixedly connected between the second piston plate 45 and the piston chamber 43. A trapezoidal plate 47 is fixedly connected to one side of the first piston plate 23. The first piston rod 44 is piston-type inserted into the slider 21. The piston-type insertion has good sealing performance and prevents lubricating oil leakage.

[0062] In this embodiment, after the lifting platform 12 moves the power turret 13 to the target machining position, the movement stops. The system then initiates a locking procedure: a pressure medium (such as compressed air or hydraulic oil) is pumped into the pressure chamber 41 located on the U-shaped seat 2 via an external air source or hydraulic pump through the filling pipe 42. The high-pressure medium then enters the piston chamber 43, which communicates with the pressure chamber 41, pushing the second piston plate 45 to move against the elastic force of the compression spring 46. The movement of the second piston plate 45 is transmitted to the inside of the slider 21 through the first piston rod 44, which is fixedly connected to it.

[0063] Secondly, please refer to it again. Figure 12 and Figure 13 The oil conveying channel 51 includes an oil storage tank 511, which is opened on the slider 21 and located at the end of the rotating shaft of the roller 22. The slider 21 is also provided with an oil inlet 512 and a diversion pipe 513, wherein the oil inlet 512 is connected to the second chamber 25, and the two ends of the diversion pipe 513 are connected to the oil inlet 512 and the oil storage tank 511 respectively.

[0064] In this embodiment, a one-way valve is provided in the oil inlet 512, which only allows oil to enter the diversion pipe 513 along the oil inlet 512 and does not allow oil to flow back.

[0065] Please refer to it again. Figure 9 The oil supply unit 52 includes an oil storage box 521, which is fixedly connected to the upper end of the slider 21. An oil supply pipe 522 is connected between the oil storage box 521 and the first chamber 24.

[0066] In this embodiment, the movement of the first piston rod 44 produces two key effects:

[0067] Braking with brake pad 26: The first piston rod 44 directly drives brake pad 26 to move towards slide rail 3 until brake pad 26 is in close contact with slide rail 3 and generates a huge static friction force. This is equivalent to applying an independent and powerful mechanical locking force between slider 21 and slide rail 3, rigidly locking the entire turret system in the target position. This locking method, which acts directly on slide rail 3, ensures the static rigidity of the turret during machining, preventing vibration or displacement caused by cutting force; on the other hand, it effectively relieves the load of cutting force on lead screw 151 and servo motor 153 during machining, preventing lead screw 151 from bending and deforming due to excessive radial force, and greatly improving the static rigidity during machining.

[0068] The piston compresses the lubricating fluid: the first piston rod 44 simultaneously drives the first piston plate 23, located in the cavity of the slider 21, to move towards the first chamber 24 (this action is called the "process"). This movement pushes the lubricating oil pre-stored in the first chamber 24 back to the oil reservoir 521 for temporary storage through the oil supply pipe 522. Since the first piston plate 23 has oil holes that allow the oil to flow slowly, after the process is completed, the oil will gradually flow from the first chamber 24 to the second chamber 25 through the oil holes to balance, preparing for the next lubrication.

[0069] When machining is complete and the turret needs to be moved again, the system releases the pressure in the pressure chamber 41. At this time, under the action of the return spring force of the compression spring 46, the second piston plate 45 drives the first piston rod 44 to move in the opposite direction (i.e., "return stroke"). The return stroke of the first piston rod 44 also drives the first piston plate 23 and the brake pad 26 to reset.

[0070] The return stroke of the first piston plate 23 is crucial for automatic lubrication: it moves towards the second chamber 25, compressing the lubricating oil already filling the second chamber 25. The compressed oil flows out through the oil inlet groove 512 (equipped with a one-way valve to prevent backflow) connected to the second chamber 25, then enters the distribution pipe 513, and is finally delivered to the oil storage groove 511 located at the end of the rotating shaft of the roller 22. Because the roller 22 is designed as a hollow structure with uniformly distributed micropores on its surface, the oil, after entering the roller 22 from the oil storage groove 511, can evenly seep out onto the outer surface of the roller 22 through these micropores. This forms a lubricating oil film on the contact surface between the roller 22 and the slide rail 3. This lubrication process occurs just before the brake pad 26 disengages from the slide rail 3 and the roller 22 begins to roll, ensuring good lubrication conditions from the initial stage of movement, further reducing frictional resistance and wear.

[0071] Please refer to it again. Figure 5 and Figures 9 to 11The recycling section 61 includes a collection trough 611, which is located at the lower end of the slider 21. A rotating rod 612 is rotatably connected to the collection trough 611 via a bearing. A water-absorbing roller 613 is mounted on the rotating rod 612. A squeezing rod 614 is also fixedly connected to the collection trough 611. One end of the rotating rod 612 extends to the outside of the slider 21 and is equipped with a pinion 615.

[0072] In this embodiment, during the turret movement, excess lubricating oil on the surface of the roller 22 adheres to the surface of the slide rail 3. Therefore, the present invention provides a recovery mechanism 6.

[0073] As the slider 21 moves along the slide rail 3, the pinion 615 meshes with the rack 31 fixedly embedded in the slide rail 3, thereby driving the rotating rod 612 and the water-absorbing roller 613 to rotate synchronously. The rotating water-absorbing roller 613 absorbs excess lubricating oil from the surface of the slide rail 3.

[0074] When the absorbent roller 613, which has absorbed oil, rotates to the position where it contacts the extrusion rod 614, it is squeezed, and the oil absorbed inside is squeezed out and drips back into the collection tank 611.

[0075] Please refer to it again. Figure 10 The return section 62 includes a collection box 621, which is fixedly connected to the collection groove 611. The upper end of the collection box 621 has a through groove 622 distributed in a ring. A T-shaped rod 623 is piston-type inserted between the collection groove 611 and the second chamber 25. The T-shaped end of the T-shaped rod 623 penetrates into the interior of the collection box 621 and is slidably connected to the collection box 621. The upper end of the T-shaped rod 623 has a through hole 624. A fixing ring 625 is fixedly sleeved on the outer wall of the T-shaped rod 623. A spring 626 is fixedly connected between the fixing ring 625 and the collection box 621.

[0076] In this embodiment, the oil in the collection tank 611 flows through the channel 622 into the collection box 621 fixed inside the tank for temporary storage. The channel 622 is equipped with a filter screen, which can filter out impurities such as metal shavings in the oil and keep the oil clean.

[0077] When the system re-enters the locked state, the first piston plate 23 moves in the "process" direction, and the trapezoidal plate 47 fixed to it moves accordingly. The trapezoidal plate 47 presses down on the top of the T-shaped rod 623, causing the T-shaped rod 623 to slide downwards against the elastic force of the spring 626, and its T-shaped end forms a squeeze within the collection box 621. This squeezing action pumps the filtered clean oil in the collection box 621 upwards through the cavity inside the T-shaped rod 623, and finally discharges it from the through hole 624 at the upper end of the T-shaped rod 623, and re-injects it into the second chamber 25. A one-way valve is provided in the cavity of the T-shaped rod 623 to ensure that the oil can only flow into the second chamber 25 in one direction. When the locking pressure is released and the trapezoidal plate 47 resets, the T-shaped rod 623 resets under the action of the spring 626, preparing for the next oil recovery. Thus, a complete closed loop of lubrication-recovery-reuse is completed.

[0078] The working principle of this invention is as follows:

[0079] When the power turret 13 needs to be adjusted, the servo motor 153 drives the lead screw 151 to move the lifting platform 12 along the slide rail 3. At this time, the brake pad 26 disengages from the slide rail 3, and the rollers 22 on both sides of the slider 21 roll on the slide rail 3 to achieve low-resistance guidance. After reaching the position, the external pressure medium enters the pressure chamber 41 of the drive unit 4, pushing the first piston rod 44 to simultaneously drive the brake pad 26 to press the slide rail 3 to achieve rigid locking. At the same time, it drives the first piston plate 23 to move towards the first chamber 24, temporarily storing the lubricating oil in the oil storage box 521. After processing is completed, the pressure is released, and the first piston rod 44 returns under the action of the compression spring 46, driving the first piston plate 23 to move in the opposite direction, so that the lubricating oil in the second chamber 25 passes through the one-way valve (located in the oil inlet groove 512) and the oil delivery channel 5. 1. The hollow rotating roller 22 is pressed in, and the lubricating oil seeps out through the micropores on the surface of the rotating roller 22 to form an oil film, providing pre-lubrication for the next movement. During the movement, the excess lubricating oil overflowing from the rotating roller 22 is absorbed by the water suction roller 613 below the slide rail 3. The water suction roller 613 moves with the slider 21 and is driven to rotate by the rack 31. Under the action of the extrusion rod 614, the oil is squeezed into the collection box 621 and temporarily stored after being filtered by the filter screen (located in the through groove 622). When the next locking action occurs, the trapezoidal plate 47 on the first piston plate 23 presses down the T-shaped rod 623 to pump the recovered clean lubricating oil back into the second chamber 25, thereby realizing the closed-loop control of lubrication-recovery-reuse, which not only ensures the positioning rigidity and movement stability, but also improves the lubrication efficiency and resource utilization.
