Description

Technical Field

[0001] This invention relates to the field of mirror polishing technology, specifically to a multi-station polishing pressure adjustment device for mirror polishing. Background Technology

[0002] Mirror polishing is a key process for achieving ultra-precision surface quality in high-end manufacturing. It is widely used in consumer electronics (such as mobile phone glass and metal frames), automotive parts (engine hoods and wheel hubs), medical devices and key aerospace components (titanium alloy blades and high-temperature alloy turbine disks). Its core objective is to achieve mirror-level smoothness and nanoscale morphology consistency while ensuring material removal efficiency.

[0003] When performing mirror polishing on a workpiece using a polishing machine, the workpiece is typically fixed to a turntable using clamping devices. The polishing machine controls the lateral movement of the polishing head and the longitudinal movement and rotation of the turntable to adjust the workpiece's polishing position. The polishing pressure is adjusted by controlling the up-and-down movement of the polishing head using the machine's cylinders. However, the polishing pressure cannot be adaptively adjusted based on the degree to which the temperature deviates from the standard threshold range during polishing. If the temperature exceeds the upper limit of the threshold range, it will lead to increased softening of the workpiece material, easily causing plastic deformation and surface distortion. If the temperature is below the lower limit, it will cause the material to harden and become brittle, potentially resulting in insufficient cutting, increased scratches, and mirror failure. All of these factors affect the polishing effect. Furthermore, the adjustment range of polishing pressure varies depending on the workpiece material (such as stainless steel, aluminum alloy, and high-temperature alloy). Therefore, we propose a multi-station polishing pressure adjustment device for mirror polishing. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-station polishing pressure adjustment device for mirror polishing, so as to solve the problems mentioned in the background art.

[0008] The mounting block has a first snap-fit ​​component on one side. The first snap-fit ​​component includes a housing that is fixedly connected to the mounting block. A second electromagnet is fixedly connected to the inside of the housing. A toothed block that attracts the second electromagnet is slidably arranged inside the housing. A second spring that is fixedly connected to the housing is symmetrically fixed to the inside of the toothed block. Two limiting toothed rods that cooperate with the toothed blocks are fixedly connected to the inside of the mounting housing.

[0009] The control component includes a connector fixedly connected to the trigger block. A first gear is provided on one side of the connector. A second gear is fixedly connected to the upper side of the first gear. A third gear is fixedly connected to the upper side of the second gear. A support rod fixedly connected to the connector is rotatably provided in the middle of the first gear, the second gear, and the third gear. A movable gear and a first gear bar are meshed on one side of the first gear. The movable gear is slidably disposed with the mounting shell. A third spring fixedly connected to the connector is fixedly connected to one side of the movable gear.

[0010] The second gear is meshed with a second rack on one side, and the third gear is meshed with a third rack on one side. The first rack, the second rack, and the third rack are slidably connected to the connecting member. A second snap-fit ​​member is provided on one side of the first rack, the second rack, and the third rack. The structure of the second snap-fit ​​member is the same as that of the first snap-fit ​​member. A toothed groove member is provided on one side of the second snap-fit ​​member and is slidably connected to the mounting shell.

[0011] The first resistor is fixedly connected to the inner side of the mounting shell. Two first contacts are slidably arranged on the first resistor. The first contacts on both sides are fixedly connected to the toothed parts on both sides respectively. The first contacts are electrically connected to the first connecting wires. The first resistor is electrically connected to a second connecting wire on one side.

[0012] The mounting housing has a third electromagnet fixedly connected to its inner side, a pressure block slidably arranged inside the mounting housing, a second magnet that repels the third electromagnet fixedly connected to one side of the pressure block, a fourth spring fixedly connected to the mounting housing fixedly connected to the other side of the pressure block, and a temperature sensor installed on one side of the polishing machine.

[0015] This invention has at least the following beneficial effects: This invention utilizes a triggering component to adjust different temperature triggering threshold ranges for workpieces made of different materials (such as stainless steel, aluminum alloy, and high-temperature alloy). The adjustment component also detects workpiece thickness and automatically adjusts the temperature triggering threshold range based on the workpiece's thickness to accommodate different materials and thicknesses during polishing. Furthermore, the control component detects the polishing temperature during workpiece processing. If the temperature exceeds the upper limit of the threshold range, the polishing pressure is automatically reduced to accommodate material softening caused by high temperatures. If the temperature falls below the lower limit, the polishing pressure is automatically increased to accommodate material hardening and embrittlement caused by low temperatures. The adjustment range of the polishing pressure can be controlled according to the degree to which the temperature exceeds or falls below the threshold range, as well as the different materials of the workpiece, to improve the polishing effect. Finally, a liquid addition component allows for the dripping of polishing liquid during polishing, and the amount of polishing liquid added can be adaptively adjusted according to changes in polishing pressure and temperature to prevent excessive or insufficient addition of polishing liquid, which could negatively impact the polishing effect.

[0018] 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.

[0019] Example 1

[0020] Please see Figures 1 to 8 The present invention provides a technical solution: a multi-station polishing pressure adjustment device for mirror polishing, comprising: a polishing machine 11, a movable stage 12 provided on the polishing machine 11, a turntable 13 provided on the movable stage 12, a clamping member 14 provided on the turntable 13, and a polishing head 15 provided on the polishing machine 11. It also includes: trigger component 2, which is located on one side of the polishing machine 11, and the trigger component 2 adjusts the temperature trigger threshold range according to the workpiece material; Adjustment component 3 is set on one side of trigger component 2. Adjustment component 3 automatically adjusts the temperature triggering threshold range of trigger component 2 according to the workpiece thickness. The control component 4 is located on one side of the trigger component 2. The control component 4 automatically adjusts the polishing pressure of the polishing machine 11 on the workpiece according to the detected workpiece polishing temperature and by triggering the threshold range of the trigger component 2. The liquid addition component 5 is located on one side of the polishing machine body 11. The liquid addition component 5 is used to add polishing liquid and automatically adjusts the amount of polishing liquid added according to the polishing pressure and polishing temperature of the workpiece.

[0021] When performing mirror polishing on a workpiece using the polishing machine 11, the workpiece is placed on the turntable 13 and clamped and fixed by the clamping member 14. The polishing machine 11 controls the longitudinal movement of the moving table 12 to adjust the longitudinal position of the workpiece. The polishing head 15 is mounted on the moving seat of the polishing machine 11. The polishing machine 11 controls the lateral movement of the moving seat to adjust the lateral position of the polishing head 15. The polishing machine 11 also controls the rotation of the polishing head 15 and the turntable 13 to perform polishing. The cylinder of the polishing machine 11 controls the up-and-down movement of the polishing head 15 and adjusts the pressure applied by the polishing head 15 during polishing. The polishing machine 11 has multiple processing stations, allowing for independent polishing of multiple workpieces. The trigger component 2 adjusts the corresponding temperature trigger threshold according to different workpiece materials (such as stainless steel, aluminum alloy, and high-temperature alloy). The temperature triggering threshold range of the triggering component 2 can be automatically adjusted according to the different thicknesses of the workpiece to adapt to different temperature triggering threshold ranges when polishing workpieces of different materials and thicknesses. The polishing temperature during workpiece processing can be detected by the regulating component 4. If the temperature exceeds the upper limit of the threshold range, the polishing pressure can be automatically reduced to adapt to the softening of materials caused by high temperature. If the temperature is lower than the lower limit of the threshold range, the polishing pressure can be automatically increased to adapt to the hardening and embrittlement of materials caused by low temperature. The adjustment range of polishing pressure can be controlled according to the degree to which the temperature exceeds or falls below the threshold range and the different materials of the workpiece to improve the polishing effect of the workpiece. The polishing liquid can be dripped during polishing by the liquid adding component 5. The amount of polishing liquid added can be adaptively adjusted according to the changes in polishing pressure and temperature to prevent the polishing liquid from being added too much or too little, which would affect the polishing effect.

[0022] The trigger assembly 2 includes a mounting shell 21 fixedly connected to one side of the polishing machine 11. Two mounting blocks 22 are provided inside the mounting shell 21. Three first switches 23 are respectively provided on one side of the two mounting blocks 22. Two electric push rods 25 are provided inside the mounting shell 21. The telescopic ends of the two electric push rods 25 are respectively fixedly connected to trigger blocks 24 that slide with the mounting shell 21. A first limiting groove adapted to the trigger block 24 is provided at the bottom of the inner side of the mounting shell 21. The trigger block 24 slides along the first limiting groove, which can guide and limit the movement of the trigger block 24. A second switch 26 is provided on one side of the trigger block 24. The side of the trigger block 24 near the mounting block 22 is set with an arc-shaped end face, which can facilitate the contact with the first switches 23. The first switches 23 on the two mounting blocks 22 are electrically connected to the two electric push rods 25 respectively.

[0023] A controller is installed on one side of the polishing machine 11. During polishing, the controller can press the control switch under the corresponding material workpiece to control the electric push rods 25 on both sides to work. The extension and retraction ends of the electric push rods 25 drive the trigger blocks 24 to move until the trigger blocks 24 press against the first switch 23 under the corresponding material. For example, for processing stainless steel workpieces, the controller can control the first switch 23 on the side closer to the third electromagnet 418 to be turned on. When the trigger blocks 24 on both sides move to touch the first switch 23 on the corresponding side, the electric push rods 25 will be stopped. At this time, the part between the second switches 26 on both sides is the corresponding temperature threshold range for stainless steel workpieces. Similarly, for aluminum alloy workpieces, the first switch 23 in the middle on both mounting blocks 22 will be turned on. For high-temperature alloy workpieces, the first switch 23 on the side of both mounting blocks 22 away from the third electromagnet 418 will be turned on, thereby adjusting the temperature threshold range corresponding to different materials.

[0024] The adjustment assembly 3 includes two first electromagnets 31 fixedly connected to the inside of the mounting shell 21. A first magnet 32 ​​that repels the first electromagnets 31 is fixedly connected to one side of the mounting block 22. A first spring 33 fixedly connected to the mounting shell 21 is fixedly connected to the other side of the mounting block 22. A second limiting groove adapted to the mounting block 22 is provided at the bottom of the inner side of the mounting shell 21. The mounting block 22 is slidably arranged along the second limiting groove, which can guide and limit the movement of the mounting block 22. A distance sensor 36 is installed on one side of the polishing machine 11. The distance sensor 36 is a laser distance sensor 36 and is electrically connected to the first electromagnets 31.

[0025] After the workpiece is placed on the turntable 13, the thickness of the workpiece can be detected by the distance sensor 36. When the workpiece is thin, the detection distance of the distance sensor 36 is relatively large, which increases the output signal of the distance sensor 36. This makes the magnetic force of the first electromagnet 31 relatively large, resulting in a greater repulsive effect on the first magnet 32. This causes the mounting block 22 to move a relatively large distance away from the first electromagnet 31. Thus, for thinner workpieces, the temperature trigger threshold range can be narrowed to meet the needs of thin workpieces that have fast heat dissipation, large temperature fluctuations, and are easily deformed by temperature. This ensures the need for timely adjustment of the polishing pressure of thin workpieces, thereby adapting to the polishing process of workpieces of different thicknesses.

[0026] A first snap-fit ​​component 35 is provided on one side of the mounting block 22. The first snap-fit ​​component 35 includes a housing 351 fixedly connected to the mounting block 22. A second electromagnet 352 is fixedly connected to the inside of the housing 351. A toothed block 353 that attracts the second electromagnet 352 is slidably provided on the inside of the housing 351. A second spring 354 fixedly connected to the housing 351 is symmetrically fixedly connected to the inside of the toothed block 353. Two limiting toothed rods 34 that cooperate with the toothed blocks 353 are fixedly connected to the inside of the mounting shell 21. The two limiting toothed rods 34 cooperate with the two toothed blocks 353 respectively.

[0027] Initially, the second electromagnet 352 is energized, attracting the toothed block 353 and causing it to slide inward toward the housing 351. The second spring 354 is compressed, separating the toothed block 353 from the limiting toothed rod 34. After the temperature threshold range is adjusted according to the thickness by the distance sensor 36, the controller de-energizes the second electromagnet 352. Under the elastic force of the second spring 354, the toothed block 353 moves outward and engages with the limiting toothed rod 34, thus maintaining the position of the adjusted mounting block 22 and maintaining the adjusted temperature threshold range.

[0028] The control component 4 includes a connector 41 fixedly connected to the trigger block 24. The connector 41 is slidably disposed with the mounting shell 21. A third limiting groove adapted to the connector 41 is provided at the bottom inner side of the mounting shell 21, and the connector 41 is slidably disposed along the third limiting groove. A first gear 42 is provided on one side of the connector 41, a second gear 43 is fixedly connected to the upper side of the first gear 42, and a third gear 44 is fixedly connected to the upper side of the second gear 43. The diameter of the third gear 44 is larger than the diameter of the second gear 43, and the diameter of the second gear 43 is larger than the diameter of the first gear 44. The diameter of 2; a support rod 45 is rotatably provided in the middle of the first gear 42, the second gear 43 and the third gear 44 through a bearing. The lower end of the support rod 45 is fixedly connected to the connecting piece 41. A movable gear 46 and a first gear 48 are meshed on one side of the first gear 42. The movable gear 46 is slidably disposed with the mounting shell 21. A fourth limiting groove adapted to the movable gear 46 is provided at the bottom inner side of the mounting shell 21. The movable gear 46 is slidably disposed along the fourth limiting groove. A third spring 47 fixedly connected to the connecting piece 41 is fixedly connected to one side of the movable gear 46.

[0029] The second gear 43 is meshed with a second rack 49 on one side, and the third gear 44 is meshed with a third rack 410 on one side. The first rack 48, the second rack 49, and the third rack 410 are respectively slidably connected to the connecting member 41, which can guide and limit the movement of the first rack 48, the second rack 49, and the third rack 410. A second locking member 411 is provided on one side of the first rack 48, the second rack 49, and the third rack 410. The structure of the second locking member 411 is the same as that of the first locking member 35. The structures are identical. The housings 351 of the three second snap-fit ​​members 411 are fixed to the first toothed rod 48, the second toothed rod 49 and the third toothed rod 410 respectively. A toothed groove member 412 is provided on one side of the second snap-fit ​​member 411 and is slidably disposed with the mounting shell 21. A fifth limiting groove adapted to the toothed groove member 412 is provided at the bottom inner side of the mounting shell 21. The toothed groove member 412 is slidably disposed along the fifth limiting groove. A toothed groove is provided on one side of the toothed groove member 412 and is engaged with the toothed block 353. The toothed block 353 can be snapped into the toothed groove of the toothed groove member 412.

[0030] A first resistor 414 is fixedly connected to the inner side of the mounting housing 21. Two first contacts 415 are slidably disposed on the first resistor 414. The first contacts 415 on both sides are fixedly connected to the toothed parts 412 on both sides respectively. A first connecting line 416 is electrically connected to the first contact 415. A second connecting line 417 is electrically connected to one side of the first resistor 414. The first resistor 414 is connected to the circuit through the second connecting line 417 and one of the first connecting lines 416, and is electrically connected to the pressure regulating valve on the air supply pipe of the cylinder of the polishing machine 11.

[0031] A third electromagnet 418 is fixedly connected to the inner side of the mounting housing 21. A pressure block 419 is slidably arranged inside the mounting housing 21. A sixth limiting groove adapted to the pressure block 419 is provided at the bottom of the inner side of the mounting housing 21. The pressure block 419 is slidably arranged along the sixth limiting groove. A second magnet 420 that repels the third electromagnet 418 is fixedly connected to one side of the pressure block 419. A fourth spring 421 fixedly connected to the mounting housing 21 is fixedly connected to the other side of the pressure block 419. The side of the pressure block 419 near the trigger block 24 is set with an arc-shaped end face to facilitate contact with the second switch 26. The pressure block 419 is located between the two moving teeth 46. A temperature sensor 413 is installed on one side of the polishing machine 11. The temperature sensor 413 is an infrared temperature sensor 413. The temperature sensor 413 is electrically connected to the third electromagnet 418.

[0032] When the first switch 23 corresponding to the workpiece material is turned on by the controller, the second electromagnet 352 of the corresponding second locking member 411 can be de-energized at the same time, so that the toothed block 353 of the corresponding second locking member 411 engages and is fixed with the toothed member 412. For example, for a high-temperature alloy workpiece, for the toothed member 412 on the side away from the third electromagnet 418, the second electromagnet 352 of the second locking member 411 on the side of the first tooth bar 48 will be de-energized, so that the toothed block 353 on the side of the first tooth bar 48 engages and is fixed with the toothed member 412 on this side; for the toothed member 412 on the side close to the third electromagnet 418, the second electromagnet 352 of the second locking member 411 on the side of the third tooth bar 410 will be de-energized, so that the toothed block 353 on the side of the third tooth bar 410 engages and is fixed with the toothed member 412 on this side. Temperature sensor 413 detects the temperature during workpiece polishing. Higher temperatures increase the output signal of temperature sensor 413, leading to a stronger repulsive force between the third electromagnet 418 and the second magnet 420. This causes the pressure block 419 to move a relatively large distance away from the third electromagnet 418, compressing the fourth spring 421. When the pressure block 419 moves to contact the second switch 26 on the side away from the third electromagnet 418, it indicates that the upper limit of the temperature threshold range has been reached. This will connect the circuit between the first connecting line 416 and the second connecting line 417 on the side away from the third electromagnet 418. Further temperature increases cause the pressure block 419 to push the moving gear 46 on the side away from the third electromagnet 418, causing the first gear 42 to rotate. Through the engagement of the toothed block 353 on the side of the first gear 48 and the toothed groove 412, the first gear 48 drives the toothed groove 412 and the first contact piece 415 to move, increasing the resistance value of the first resistor 414. The controller can then reduce the opening of the pressure regulating valve on the air supply line of the polishing machine 11's cylinder, thereby reducing the gas pressure inside the cylinder and thus lowering the polishing pressure. Conversely, at lower temperatures, when the pressure block 419 touches the second switch 26 near the third electromagnet 418, it indicates that the lower limit of the temperature threshold range has been reached. This will control the circuit where the first connecting line 416 and the second connecting line 417 are located near the third electromagnet 418 to be connected. At this time, the continued movement of the pressure block 419 can drive the circuit near the third electromagnet 418 to be connected. The moving tooth 46 on one side of the iron 418 moves closer to the third electromagnet 418. Through the engagement of the toothed block 353 on the side of the third toothed rod 410 with the toothed groove 412 on the same side, the toothed groove 412 and the first contact piece 415 can be driven to move closer to the third electromagnet 418, so that the resistance value of the first resistor 414 is reduced. Through the controller, the opening of the pressure regulating valve on the air supply pipe of the polishing machine 11 can be increased, so that the gas pressure in the cylinder increases, thereby increasing the polishing pressure.

[0033] For aluminum alloy workpieces, the second electromagnet 352 of the second latching member 411 on one side of the second toothed rod 49 is de-energized, causing the toothed blocks 353 on one side of the second toothed rod 49 to engage and fix with the toothed groove members 412 on both sides respectively. For stainless steel workpieces, for the toothed groove member 412 on the side away from the third electromagnet 418, the toothed blocks 353 on the side of the third toothed rod 410 are engaged and fixed with the toothed groove member 412 on this side. For the toothed groove member 412 on the side closer to the third electromagnet 418, the toothed blocks 353 on the side of the first toothed rod 48 are engaged and fixed with the toothed groove member 412 on this side, and the first gear 42, the second gear 43, and the third gear 44 are engaged and fixed. The wheel ratio setting allows for a relatively small movement distance for the toothed part 412 and the first contact piece 415 on the side away from the third electromagnet 418 when the temperature exceeds the upper limit of the threshold range for high-temperature alloy workpieces. For aluminum alloy workpieces, the movement distance of the first contact piece 415 is the second largest, while for stainless steel workpieces, the movement distance of the first contact piece 415 is relatively large. Thus, for high-temperature alloy workpieces, the reduction in polishing pressure is relatively small when the temperature exceeds the upper limit of the threshold range, followed by aluminum alloy workpieces, and the reduction in polishing pressure is relatively large for stainless steel workpieces. This is to accommodate the fact that high-temperature materials do not soften significantly at high temperatures, and therefore the reduction in polishing pressure is relatively small. When the temperature is below the lower threshold, for high-temperature alloy workpieces, the toothed part 412 and the first contact piece 415 on the side near the third electromagnet 418 can move a relatively large distance, followed by aluminum alloy workpieces, and relatively small for stainless steel workpieces. This results in a relatively large increase in polishing pressure for high-temperature alloy workpieces, followed by aluminum alloy workpieces, and relatively small increase in polishing pressure for stainless steel workpieces. This is to adapt to the requirement that high-temperature materials become hard and brittle at low temperatures, requiring greater pressure for polishing. Thus, the adjustment range of polishing pressure can be controlled for different workpiece materials, improving the polishing effect on the workpieces.

A second resistor 55 is fixedly connected between the two connecting blocks 54. A second contact piece 56 is slidably disposed on the second resistor 55. A connecting rod 57 fixedly connected to the pressure block 419 is fixedly connected to one side of the second contact piece 56. The second resistor 55 is electrically connected to the delivery pump 53 through the second contact piece 56, and the resistance value of the second resistor 55 on the side of the second contact piece 56 away from the fifth spring 510 is connected to the circuit. When the temperature is detected by the temperature sensor 413, the pressure block 419 moves. The connecting rod 57 drives the second contact piece 56 to move. When the temperature is high, the resistance value of the second resistor 55 is relatively small. The controller enables the delivery pump 53 to have a relatively high power, resulting in a relatively large amount of polishing liquid being added to cope with the high temperature. Conversely, when the temperature is low, the amount of polishing liquid being added is relatively small to prevent excessive polishing liquid from being wasted. Thus, the amount of polishing liquid added can be adaptively adjusted according to the temperature change during workpiece polishing to improve the polishing effect.

[0037] A third magnet 58 is fixedly connected to one side of the connecting block 54, and a fourth electromagnet 59 that repels the third magnet 58 is fixedly connected to the inside of the mounting shell 21. A fifth spring 510 that is fixedly connected to the mounting shell 21 is fixedly connected to one side of the connecting block 54. A pressure sensor is installed on the polishing head 15 of the polishing machine 11 to detect the polishing pressure (not shown in the figure, which belongs to the prior art). The fourth electromagnet 59 is electrically connected to the pressure sensor. When the polishing pressure is high, the pressure sensor output signal increases due to detection, resulting in a relatively strong repulsive force between the fourth electromagnet 59 and the third magnet 58. This causes the connecting block 54 and the second resistor 55 to move a relatively large distance away from the fourth electromagnet 59. The fifth spring 510 is compressed, further reducing the resistance value of the second resistor 55. This allows for a further increase in the amount of polishing slurry added, meeting the polishing requirements of higher polishing pressures. Consequently, the amount of polishing slurry added can be adjusted according to the polishing pressure to further improve the polishing effect.
