It includes a slide table body, with a drive screw rotatably connected internally. A drive slide block is threadedly connected to the surface of the drive screw. The drive slide block is slidably connected to a limiting slide rail fixed to the surface of the slide table body by multiple sets of support blocks.

Description

Technical Field

[0001] This invention belongs to the field of linear motor slide technology, specifically relating to an adaptive linkage linear motor control slide. Background Technology

[0002] In fields such as automated production, precision machining, and intelligent equipment, linear motor slides are core components for achieving high-precision linear feed motion. Their operational stability, motion accuracy, and service life directly determine the working performance and processing quality of the entire machine. The core motion pairs of linear motor slides mainly include the drive screw and drive slide, and the limit slide rail and slider. These components generate severe friction during high-speed reciprocating motion. If lubrication is not timely or uniform, it will lead to increased wear of the motion pairs and increased running resistance. This will not only reduce the motion accuracy and response speed of the slide, but also shorten the service life of parts, increase equipment maintenance costs, and even cause malfunctions such as jamming and abnormal noise, affecting production efficiency and processing quality.

[0003] However, the existing lubrication mechanisms of linear motor slides mostly adopt fixed-frequency oil supply or manual periodic oil replenishment, which has many technical defects. On the one hand, the oil supply frequency cannot be synchronized with the slide speed. When the slide runs at high speed, fixed-frequency oil supply is difficult to meet the lubrication needs of the moving parts, which easily leads to insufficient lubrication and increased friction loss. On the other hand, when the slide runs at low speed, fixed-frequency oil supply will cause a lot of waste of lubricating oil. At the same time, excessive lubricating oil is easy to splash, causing environmental and equipment pollution. In addition, the nozzles of the existing lubrication mechanism mostly adopt the traditional drip oil design, which has a limited lubrication coverage and is prone to lubrication dead zones. This leads to uneven lubrication of key parts such as the thread surface of the drive screw and the working surface of the limit slide rail, which further affects the lubrication effect and aggravates the wear of parts.

[0004] To address the aforementioned issues, this application proposes an adaptive linkage linear motor control slide. Summary of the Invention

[0012] Preferably, the oil tank is provided with an oil level observation window, the oil level observation window has an oil level scale line, a first liquid level sensor is fixed at the bottom of the inner cavity of the oil tank, and a temperature sensor is fixed inside the oil tank, which are used to detect the liquid level and temperature of the lubricating oil in the oil tank, respectively. A heating plate is installed in the bottom wall of the oil tank for heating and keeping the lubricating oil warm in low temperature environments.

[0013] Preferably, the oil storage tank is rotatably connected to a stirring shaft, the drive slide surface near the oil storage tank is rotatably connected to a transmission shaft, the drive shaft and the transmission shaft are connected by a fifth bevel gear pair, and the transmission shaft and the stirring shaft are connected by a transmission chain via a sprocket.

[0015] Preferably, a flow-guiding slope is provided on one side of the slide body near the two sets of limiting slide rails. A waste oil recovery hopper is fixed at the bottom center of the slide body. The flow-guiding slope is inclined to the center of the slide body to guide the lubricating oil into the waste oil recovery hopper at the bottom of the slide body. A filter screen is installed inside the waste oil recovery hopper. A collection box is connected to the bottom of the waste oil recovery hopper. A second liquid level sensor is fixed inside the collection box. A return oil pump is fixed on the surface of the slide body. An oil suction pipe is connected between the input end of the return oil pump and the collection box. An oil return pipe is connected between the output end of the return oil pump and the oil storage tank to pump the filtered waste oil back into the oil storage tank for recycling.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. Achieving adaptive linkage between slide table movement and lubrication supply improves lubrication accuracy and effectiveness. Through the linkage design of moving wheels, transmission pairs, drive shafts, and multiple sets of bevel gear pairs, the linear motion of the drive slide is converted into the rotational motion of each driven shaft and transmission shaft. This, in turn, drives the reciprocating motion of the piston rod of the oil supply cylinder and the alternating opening and closing of the sealing plate. This achieves adaptive control that synchronizes the slide table movement speed with the oil supply frequency. When the drive slide speed increases, the oil supply frequency increases accordingly; conversely, when the slide table moves at low speed, the oil supply frequency decreases accordingly. This adaptive linkage mode avoids the waste of lubricating oil during low-speed operation and ensures sufficient lubrication of moving pairs such as the drive screw and limit slide rail during high-speed operation. It effectively reduces frictional losses between moving pairs, lowers the wear rate of parts, extends the overall service life of the slide table, and improves the stability and accuracy of the slide table movement.

[0017] Meanwhile, the lubrication nozzles adopt an atomizing structure and are evenly distributed along the direction of movement of the drive slide. The nozzles are precisely oriented towards the threaded surface of the drive screw and the working surface of the limit slide rail, which can atomize the lubricating oil and spray it evenly to each lubrication part, avoiding the occurrence of lubrication dead corners and further improving the lubrication uniformity. Compared with traditional drip lubrication, atomized lubrication can expand the lubrication coverage area, reduce lubricating oil consumption, and reduce the pollution caused by oil splashing.

[0018] 2. Optimize the power transmission structure to ensure transmission stability and reliability. By symmetrically setting moving wheels on both sides of the drive slide, and designing a matching elastic compensation structure of compensation sleeve, compensation rod and spring one, the compensation rod adapts to the expansion and contraction within the compensation sleeve by relying on the elastic preload of spring one. This ensures that the moving wheel is always in close contact with the inner wall of the groove on the surface of the slide body, effectively eliminating assembly gaps and vibration gaps during movement. This ensures the rotational stability of the moving wheel when it slides with the drive slide, thereby ensuring the stable and reliable power transmission to the drive shaft through the transmission pair and avoiding slippage and jerking during power transmission.

[0019] 3. Improve the oil management system, enhance oil utilization, and reduce operation and maintenance costs. Through the waste oil recycling system composed of a diversion slope, waste oil recovery hopper, filter screen, collection box, and return oil pump, the waste oil dripping after spraying can be collected along the diversion slope towards the middle of the slide body and flow into the waste oil recovery hopper by gravity. After being filtered by the filter screen to remove metal debris, impurities, and other contaminants, it flows into the collection box for temporary storage. Through the electronic control linkage of the first liquid level sensor, the second liquid level sensor, and the return oil pump, the automatic recovery and replenishment of waste oil can be realized, which not only avoids waste oil waste but also reduces the frequency of lubricating oil replenishment, thereby reducing operation and maintenance costs and environmental pollution.

[0020] The oil tank is equipped with a stirring mechanism consisting of a stirring shaft, stirring blades, a driving gear, a driven gear, a driven shaft, and an impeller. Driven by the transmission shaft and transmission chain, the mechanism can agitate the lubricating oil throughout the tank, effectively preventing the lubricating oil from separating due to static conditions. Especially after adding lubricating additives, it can achieve thorough mixing and homogenization between the additives and the base oil, ensuring uniform physicochemical properties of the lubricating oil and improving lubrication performance. At the same time, the oil tank is equipped with a graduated oil level observation window, a first liquid level sensor, and a temperature sensor, which can monitor the lubricating oil level and temperature in real time. This allows staff to intuitively grasp the oil status, replenish the lubricating oil in a timely manner, and avoid lubrication failure caused by insufficient oil level or oil deterioration.

[0021] 4. Improved adaptability to low-temperature conditions and expanded application range of the slide table: By installing a heating plate inside the bottom wall of the oil tank, and with real-time monitoring by a temperature sensor, the lubricating oil in the oil tank can be heated and kept warm in low-temperature environments. This effectively prevents the lubricating oil from losing its fluidity due to solidification at low temperatures, ensuring that the lubrication mechanism can still work normally under low-temperature conditions. This breaks through the limitations of traditional linear motor slide tables that fail to lubricate and cannot operate stably in low-temperature environments, expanding the application scenarios of the slide table. It can be used in various harsh conditions such as low-temperature workshops and outdoor low-temperature operations, improving the environmental adaptability and practicality of the slide table.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1-14As shown, the present invention provides a technical solution for an adaptive linkage linear motor controlled slide table, comprising a slide table body 1, a drive screw 2 rotatably connected inside the slide table body 1, a drive slide 4 threadedly connected to the surface of the drive screw 2, the drive slide 4 slidably connected to a limiting slide rail 5 fixed on the surface of the slide table body 1 by multiple sets of support blocks 7, a bearing platform 8 fixed above the drive slide 4, an oil reservoir 9 fixed on the surface of the drive slide 4, and an oil supply cylinder 16 fixed on the surface of the drive slide 4. An oil inlet pipe 38 is provided between the tanks 9. Lubrication nozzles 39 are fixed on the side of the drive slide 4 facing the drive screw 2 and the limit slide rail 5 respectively. An oil outlet pipe 37 is provided between the oil supply cylinder 16 and the lubrication nozzle 39. A sealing seat 34 is connected between the oil supply cylinder 16, the lubrication nozzle 39 and the oil outlet pipe 37. A sealing plate 35 is slidably connected inside the sealing seat 34. The oil outlet pipe 37 is connected to the lubrication nozzle 39. The oil inlet pipe 38 is connected to the oil storage tank 9. A piston rod 24 is slidably connected inside the oil supply cylinder 16.

[0026] like Figures 1-5 As shown, symmetrical movable wheels 13 are arranged on both sides of the drive slide 4. The wheel body of the movable wheel 13 fits into the groove opened on the surface of the slide body 1. One set of movable wheels 13 is rotatably connected to the drive slide 4 through a bearing seat and a drive shaft 14. The wheel axle of the movable wheel 13 is connected to the drive shaft 14 through a transmission pair 15. The drive motor 3 outputs power to drive the drive screw 2 to rotate inside the slide body 1. The drive screw 2 drives the drive slide 4 to slide horizontally and linearly along the limit slide rail 5 through threaded transmission. During the sliding process, the top support platform 8 is driven to follow the movement. Two sets of movable wheels 13 are symmetrically arranged on both sides of the drive slide 4. The wheel body of the movable wheel 13 fits into the inner wall of the groove on the surface of the slide body 1.

[0027] like Figures 1-5 As shown, a compensating sleeve 11 is fixed to the surface of the movable wheel 13, and a compensating sleeve 10 is fitted onto the surface of the compensating sleeve 11. The compensating sleeve 10 is fixedly installed on the lower surface of the bearing platform 8. A receiving groove adapted to the compensating sleeve 11 is opened inside the compensating sleeve 10, and a spring 12 is fixed between the compensating sleeve 10 and the compensating sleeve 11. The elastic force of the spring 12 keeps the movable wheel 13 in contact with the surface of the slide body 1. The movable wheel 13 is equipped with a compensating sleeve 10, a compensating sleeve 11 and a spring 12. Relying on the elastic preload of the spring 12, the compensating sleeve 11 adaptively extends and retracts within the compensating sleeve 10, always ensuring that the movable wheel 13 is in close contact with the surface of the slide body 1, eliminating assembly gaps and ensuring stable and reliable power transmission.

[0028] like Figures 1-9As shown, a support frame 19 is fixed to the side of the drive slide 4 near the oil supply cylinder 16. A push rod 20 is slidably connected to one side of the support frame 19. An abutment 21 is fixed to the bottom end of the push rod 20. A spring 22 is sleeved on the surface of the push rod 20, and the two ends of the spring 22 are respectively fixed between the support frame 19 and the abutment 21. The bottom end of the abutment 21 abuts against a push cam 18. A first driven shaft 17 is fixed inside the push cam 18. The first driven shaft 17 is rotatably connected to the surface of the drive slide 4 through a bearing bracket. The drive shaft 14 and the first driven shaft 17 are connected by a first bevel gear pair 25. A rocker arm 23 is hinged to the top of the support frame 19. Both ends of the rocker arm 23 are hinged to the piston rod 24 through clearance grooves and the push rod 20. One set of movable wheels 13 has its axle connected to the drive shaft 14 via a transmission pair 15 to form a synchronous transmission. When the movable wheels 13 rotate as the drive slide 4 slides, they can drive the drive shaft 14 to rotate synchronously. During the rotation of the drive shaft 14, the first driven shaft 17, the second driven shaft 26, the third driven shaft 28, and the transmission shaft 40 are driven synchronously through the first bevel gear pair 25, the second bevel gear pair 27, the third bevel gear pair 29, and the fifth bevel gear pair 41, respectively, so as to realize the linkage matching between the sliding speed of the slide table and the rotation speed of each transmission shaft. The first driven shaft 17 drives the push cam 18 to rotate synchronously. The contour surface of the push cam 18 continuously abuts against the contact joint 21. With the reset action of the support frame 19, the push rod 20, and the second spring 22, the push rod 20 is driven to make vertical reciprocating sliding. The push rod 20 is driven by the hinged rocker arm 23 to drive the piston rod 24 to make up-down reciprocating sliding inside the oil supply cylinder 16.

[0029] like Figures 1-12 As shown, the oil supply cylinder 16 is rotatably connected to the second driven shaft 26 and the third driven shaft 28 via bearing brackets on the side near the oil outlet pipe 37 and the oil inlet pipe 38, respectively. The drive shaft 14 and the second driven shaft 26 and the third driven shaft 28 are respectively connected by the transmission of the second bevel gear pair 27 and the third bevel gear pair 29.

[0030] like Figures 6-12As shown, the drive slide 4 has rotating shafts 30 rotatably connected to the side of the drive slide 4 near the second driven shaft 26 and the third driven shaft 28 via bearing brackets. The rotating shafts 30 and the second and third driven shafts 26 and 28 are respectively connected by a fourth bevel gear pair 31. A sealing cam 32 is fixed to the surface of each of the two sets of rotating shafts 30. A pressure roller 33 is attached to the contour surface of each of the two sets of sealing cams 32. The pressure roller 33 is fixed to the top of the sealing plate 35. A spring 36 is fixed between the pressure roller 33 and the sealing seat 34. The two sets of sealing cams 32 are staggered, driving the sealing plates 35 at the oil outlet pipe 37 and oil inlet pipe 38 to open and close alternately. The second driven shaft 26 and the third driven shaft 28 drive the rotating shafts 30 on both sides to rotate via the fourth bevel gear pair 31. The rotating shafts 30 drive the sealing cams 32 to rotate synchronously. The two sets of sealing cams 32 are arranged in staggered phases, rolling with the corresponding pressure rollers 33. Under the reset action of 36, the driving sealing plate 35 slides vertically back and forth inside the sealing seat 34, realizing the alternating opening and closing of the oil inlet pipe 38 and the oil outlet pipe 37. When the piston rod 24 slides downward, the internal volume of the oil supply cylinder 16 decreases and the oil pressure increases. At this time, the sealing plate 35 on the side near the oil outlet pipe 37 opens and the sealing plate 35 on the side near the oil inlet pipe 38 closes. The pressurized lubricating oil in the oil supply cylinder 16 is diverted to each group of lubrication nozzles 39 through the oil outlet pipe 37. 39 adopts an atomization structure to atomize the lubricating oil and spray it evenly onto the threaded surface of the drive screw 2 and the working surface of the limit slide rail 5, thus completing the automatic lubrication of the moving pair. When the piston rod 24 slides upward, a negative pressure chamber is formed inside the oil supply cylinder 16. At this time, the sealing plate 35 on the side near the oil inlet pipe 38 opens and the sealing plate 35 on the side near the oil outlet pipe 37 closes. The lubricating oil in the oil storage tank 9 is drawn into the oil supply cylinder 16 through the negative pressure of the oil inlet pipe 38, completing the oil storage and replenishment, and preparing for the next oil pressure lubrication.

[0031] like Figures 6-13As shown, the oil tank 9 is equipped with an oil level observation window 52, ​​which has an oil level scale. A first liquid level sensor 50 is fixed at the bottom of the inner cavity of the oil tank 9, and a temperature sensor 51 is fixed inside the oil tank 9, which are used to detect the liquid level and temperature of the lubricating oil in the oil tank 9, respectively. A heating plate 49 is installed in the bottom wall of the oil tank 9 for heating and keeping the lubricating oil warm in low-temperature environments. The operator adds lubricating oil of appropriate specifications into the oil tank 9 through the filling port on the slide body 1, and uses the oil level observation window 52 with scale on the side of the oil tank 9 to visually observe the oil level in the tank, ensuring that the lubricating oil is filled to the standard working level. The first liquid level sensor 50 and temperature sensor 51 are installed inside the tank 9. A heating plate 49 is embedded in the bottom wall. Under low temperature conditions, the heating plate 49 can heat and keep the lubricating oil in the oil tank 9 warm, preventing the lubricating oil from solidifying at low temperature and ensuring that the entire lubrication mechanism has normal working viscosity and fluidity. The faster the drive slide 4 and the bearing platform 8 move, the higher the rotation speed of the moving wheel 13 and the drive shaft 14. The reciprocating frequency of the piston rod 24 driven by the push cam 18 and the opening and closing frequency of the sealing plate 35 controlled by the sealing cam 32 are accelerated synchronously. The oil supply frequency is automatically adapted to the slide table feed speed to achieve adaptive linkage lubrication with high speed and high lubrication frequency and low speed and low lubrication frequency.

[0032] like Figures 6-13 As shown, an agitator shaft 42 is rotatably connected inside the oil storage tank 9, and a drive shaft 40 is rotatably connected to the side of the drive slide 4 near the oil storage tank 9. A fifth bevel gear pair 41 is connected between the drive shaft 14 and the drive shaft 40. A drive chain 43 is connected between the drive shaft 40 and the agitator shaft 42 through a sprocket.

[0033] like Figure 13 As shown, a drive gear 45 is fixedly installed at the bottom of the stirring shaft 42. Several sets of driven gears 46 are meshed in a ring array on the outer side of the drive gear 45. A driven shaft 47 is fixed inside the driven gear 46. An impeller 48 is fixed at the top of the driven shaft 47. A stirring blade 44 is fixed on the upper surface of the stirring shaft 42. The bottom of the oil storage tank 9 has a drive cavity adapted to the drive gear 45 and the driven gears 46. The transmission shaft 40 rotates synchronously with the drive shaft 14 under the transmission of the fifth bevel gear pair 41. The transmission shaft 40 drives the stirring shaft 42 in the oil storage tank through the transmission chain 43. The internal rotation of the tank 9 is as follows: the bottom of the stirring shaft 42 is fixed with a drive gear 45, and the outer side of the drive gear 45 is connected to multiple driven gears 46 in a ring array. The driven gears 46 rotate differentially with the drive gear 45 and drive the driven shaft 47 to rotate synchronously. The stirring blades 44 on the upper part of the stirring shaft 42 cooperate with the impeller 48 at the top of the driven shaft 47 to rotate synchronously, which stirs and disturbs the lubricating oil in the oil storage tank 9 throughout the entire area. This can effectively prevent the lubricating oil from settling and separating. After adding lubricating additives, the additives and base oil can be fully mixed and homogenized, ensuring that the physical and chemical properties of the lubricating oil are uniform and improving the overall lubrication and protection effect.

[0034] like Figures 1-14 As shown, a flow-guiding slope 6 is provided on one side of the slide body 1 near the two sets of limiting slide rails 5. A waste oil recovery hopper 53 is fixed at the bottom center of the slide body 1. The flow-guiding slope 6 is inclined towards the center of the slide body 1 to guide the lubricating oil into the waste oil recovery hopper 53 at the bottom of the slide body 1. A filter screen 54 is installed inside the waste oil recovery hopper 53. A collection box 55 is connected to the bottom of the waste oil recovery hopper 53. A second liquid level sensor 56 is fixed inside the collection box 55. A return oil pump 57 is fixed on the surface of the slide body 1. An oil suction pipe 58 is connected between the input end of the return oil pump 57 and the collection box 55. The output end of the return oil pump 57 is connected to the oil storage tank 9. An indirect oil return pipe 59 is connected to the oil storage tank 9 for recycling the filtered waste oil. Multiple sets of lubrication nozzles 39 are provided and equidistantly distributed along the movement direction of the drive slide block 4. The nozzles of the lubrication nozzles 39 face the threaded surface of the drive screw 2 and the working surface of the limiting slide rail 5, respectively. The lubrication nozzles 39 employ an atomizing nozzle structure to atomize the lubricating oil and spray it evenly onto the lubrication points. The first liquid level sensor 50 and the second liquid level sensor 56 are both electrically connected to the oil return pump 57. The first liquid level sensor 50 collects the oil level signal inside the oil storage tank 9 in real time, and the second liquid level sensor 56 collects the oil level signal inside the collection tank 55 in real time. When the second liquid level sensor 56 detects that the oil level inside the collection tank 55 exceeds a set high threshold, the control system triggers the start and stop of the oil return pump 57. The oil return pump 57 draws the filtered waste oil from the collection tank 55 through the suction pipe 58 and returns it to the oil storage tank 9 through the oil return pipe 59, achieving automatic waste oil replenishment and recycling. When the first liquid level sensor 50 detects that the oil level inside the oil storage tank 9 is lower than the set low threshold, the control system synchronously starts the return oil pump 57 to replenish the oil stored in the collection tank 55 into the oil storage tank 9; at the same time, the system triggers the liquid level abnormality alarm mechanism to provide audible and visual warnings or signal alarm prompts, realizing the linkage control of low oil level monitoring and automatic oil replenishment. The slide body 1 is provided with drainage slopes 6 on both sides. The waste oil dripping after spraying collects along the drainage slopes 6 towards the middle and flows into the waste oil recovery hopper 53 fixed at the bottom center. The waste oil recovery hopper 53 has a built-in filter screen 54, which can filter and purify the metal debris and impurities in the recovered waste oil. The filtered clean waste oil flows into the collection tank 55 connected at the bottom for temporary storage. The collection tank 55 is equipped with a second liquid level sensor 56, and the oil storage tank 9 is equipped with a first liquid level sensor 50. The first liquid level sensor 50 and the second liquid level sensor 56 are both interconnected with the return oil pump 57 through electrical control signals.

[0035] When the second liquid level sensor 56 detects that the oil level in the collection tank 55 exceeds the preset high threshold, the control system automatically starts the return oil pump 57. The return oil pump 57 draws filtered waste oil from the collection tank 55 through the suction pipe 58, and then transports it back to the oil storage tank 9 through the return oil pipe 59, realizing automatic waste oil recycling. When the first liquid level sensor 50 detects that the oil level in the oil storage tank 9 is lower than the preset low threshold, the control system also starts the return oil pump 57, and the collection tank 55 automatically replenishes oil to the oil storage tank 9. At the same time, it triggers an audible and visual alarm or an electrical signal alarm for abnormal liquid level, reminding maintenance personnel to check the oil status, realizing integrated control of real-time oil level monitoring, automatic oil return and replenishment, and abnormal alarm.
