Description

Technical Field

[0001] The present invention relates to the technical field of linear motors, and specifically to a linear motor slide table structure. Background Art

[0002] In the field of modern industrial automation, as a key component for achieving precise linear motion, the linear motor slide table structure is widely used in various high-precision equipment and production lines. With the continuous improvement of the requirements for equipment accuracy, stability, and reliability in industrial production, the performance optimization and safety protection measures of the linear motor slide table structure have become increasingly important. During the operation of the traditional linear motor slide table structure, due to the relative movement between the mover and the limit slide bar, friction will inevitably occur. Long-term friction will cause the limit slide bar to heat up. Excessive temperature will not only affect the motion accuracy of the slide table, but may also damage the mechanical structure and related components of the slide table, reducing the service life of the equipment. In addition, under certain working conditions, the linear motor slide table may be affected by external excitation or its own operating characteristics and generate resonance. Once resonance occurs, it will cause the equipment to vibrate violently, which will not only seriously affect the processing accuracy and product quality, but may even cause equipment failures, resulting in production interruptions and economic losses; To solve the above problems, some methods have been proposed in the prior art. For example, by improving the material and surface treatment process of the limit slide bar to reduce the friction coefficient and heat generation; using shock absorption devices or adjusting the control system parameters to suppress the generation of resonance. However, these methods often have certain limitations. Improving the material and surface treatment process may increase costs and it is difficult to retrofit the equipment that has already been put into use. And the shock absorption devices and control system adjustments may not be able to completely eliminate the influence of resonance, or may require complex debugging processes in practical applications.

[0003] Therefore, it is of great practical significance to develop a linear motor slide table structure that can automatically cut off power for protection when the mover moves and causes the limit slide bar to overheat or generate resonance. This innovative slide table structure can effectively avoid the damage caused to the equipment by overheating and resonance, improve the reliability and safety of the equipment, reduce the maintenance cost, and meet the needs of modern industrial production for high-precision and high-reliability equipment.

[0004] Chinese Patent (Publication No. CN115296479A), which discloses a linear motor slide structure, including a base, a slide rail, a screw rod and a slide table. A chute is provided inside the slide rail, and an airbag is fixedly connected to the right side of the chute. Spherical grooves are provided on both the upper and lower sides where the slide rail contacts the slide table. A groove corresponding to the upper spherical groove is provided on the part of the slide table that contacts the slide rail and cooperates with the upper spherical groove to form a sphere. A second ball is movably placed in the groove. An air outlet groove is provided inside the slide rail and outside the spherical groove. When the screw rod drives the slide table to move, the movable plate is driven to move, so as to squeeze the airbag by the movable plate, so that the gas inside the airbag enters the spherical groove through the air delivery groove and the air outlet groove, prompting the second ball inside the spherical groove to fit with the slide table. At the same time, the sliding friction between the slide table and the slide rail is transformed into the rolling friction of the second ball, reducing the wear when the slide table slides and increasing the service life of the slide table.

[0005] According to the above solution, when the above solution is used, only the ball is used to reduce the frictional resistance and extend the service life. However, when resonance occurs, it cannot be automatically shut down, which has limitations. To solve the problem that it cannot be automatically shut down and has limitations when resonance occurs, for this reason, we propose a linear motor slide structure. Summary of the Invention

[0006] The purpose of the present invention is to provide a linear motor slide structure to solve the problems raised in the above background technology.

A trigger mechanism is fixedly installed between each limit slide rod and the cooperation moving plate. A power-off mechanism is also installed between the cooperation moving plate and each limit slide rod. When a mover moves, generates vibration or the limit slide rod overheats due to friction, the power-off mechanism is activated through the trigger mechanism to cut off the power supply of the whole device and prevent damage to the whole device.

[0008] As a further improvement of this solution, the trigger mechanism includes a first swing arm, which is rotatably connected to the bottom of the cooperation moving plate. The bottom of the first swing arm is fixedly connected with a trigger tube, and the bottom of the trigger tube is also rotatably connected with a second swing arm.

[0009] As a further aspect of this solution, a counterweight is rotatably connected to the bottom of the second swing arm. A plurality of abutment boxes are arranged inside the trigger tube. Each of the abutment boxes is filled with a water-ethylene glycol mixture. Two sliding columns are fixedly connected to one end of each abutment box close to the trigger tube.

[0010] As a further aspect of this solution, two first springs are fixedly connected between the abutment box and the trigger tube. Each of the first springs is sleeved on the outer wall of the corresponding sliding column. A cooperating shrinkage tube is fixedly connected between every two sliding columns.

[0011] As a further aspect of this solution, an abutment block is fixedly connected to one end of the cooperating shrinkage tube away from the sliding column. One end of each abutment box away from the trigger tube abuts against the outer wall of the corresponding limiting slide rod. Each of the cooperating shrinkage tubes is fixedly communicated with the corresponding abutment box through a pipeline.

[0012] As a further aspect of this solution, the power-off mechanism includes a cooperating arm. The cooperating arm is fixedly connected to the bottom of the cooperating moving plate. A plurality of cooperating round rods are fixedly connected to one end of the cooperating arm close to the trigger tube. A first moving ring with a reset function is slidably connected between the outer walls of all the cooperating round rods.

[0013] As a further aspect of this solution, a butting tube is slidably connected between the outer walls of all the cooperating round rods. A third spring is fixedly connected between the butting tube and the cooperating round rods. The third spring is sleeved on the outer wall of the cooperating round rods. A fixing ring is also fixedly connected to the bottom of the cooperating arm. A fixing ring is fixedly connected to the bottom of the cooperating arm.

[0014] As a further aspect of this solution, a plurality of clamping arms are fixedly connected to one end of the butting tube close to the fixing ring. A plurality of clamping openings are also formed in the outer wall of the fixing ring. The outer wall of each clamping arm is slidably connected to the inner wall of the corresponding clamping opening. A sliding opening is formed in the clamping arm.

[0015] As a further aspect of this solution, a cooperating clamping block is slidably connected to the inside of each sliding opening. The cooperating clamping block is fixedly connected to the inner wall of the sliding opening through a fourth spring. The outer wall of the cooperating clamping block abuts against the outer wall of the second moving ring.

[0016] As a further aspect of this solution, a cooperating socket is fixedly connected to one end of the cooperating moving plate close to the cooperating arm. A connecting plate is fixedly connected to the outer wall of the cooperating box through bolts. A clamping plug is inserted into the cooperating socket. The clamping plug is fixedly connected to the connecting plate through a circuit. And a shrinkage corrugated sleeve is fixedly connected between the clamping plug and the connecting plate. The clamping plug is fixedly connected to the second moving ring through a connecting arm.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. When the present invention is in use, when the linear motor slide table resonates, the counterweight block sways under the vibration of the cooperating moving plate, driving the first swing arm, the trigger tube and the second swing arm to swing greatly. The trigger tube sways and pushes against the abutting tube, driving the clamping arm to move so that the cooperating clamping block is squeezed into the sliding opening by the clamping opening, releasing the limit on the second moving ring. Then the second spring pushes the second moving ring, driving the clamping plug to disengage from the cooperating socket through the connecting arm, realizing rapid power-off and shutdown. This pure mechanical linkage structure does not require an electronic monitoring system, which not only reduces costs and is convenient for maintenance, but also can quickly respond at the moment of resonance, effectively preventing the equipment from being damaged by vibration. Its delicate design ensures sensitive triggering, with a small displacement but rapid triggering of power-off, greatly improving the safety and reliability of the equipment operation and adapting to various industrial scenarios with strict requirements for stability.

[0018] 2. When the present invention is in use, when the limiting slide rod and the cooperating moving plate rub against each other for a long time and the temperature exceeds 80 degrees, the heat is conducted to the abutting box. The water-ethylene glycol mixture in the box expands due to heat, causing the cooperating shrinkage tube to elongate and driving the abutting block to spread out around the abutting box, further pushing the abutting tube to move. Through the linkage structure, the clamping plug disengages from the cooperating socket to cut off the power. Using the principle of thermal expansion and contraction, automatic power-off protection against overheating is achieved with a pure mechanical structure, without the need for complex electronic components, effectively preventing equipment components from being damaged and performance from declining due to continuous high temperature, significantly improving the safety and reliability of the linear motor slide table operation, and being applicable to industrial automation scenarios with strict requirements for temperature control.

A trigger mechanism 101 is fixedly installed between each limiting slide bar 6 and the matching movable plate 5. A power-off mechanism 201 is also installed between the matching movable plate 5 and each limiting slide bar 6. When the mover 34 moves and generates vibration or the limiting slide bar 6 is overheated by friction, the power-off mechanism 201 is activated by the trigger mechanism 101 to cut off the power of the entire device and prevent damage to the entire device.

[0030] Example 2: Please refer to Figures 2 to 6As shown, the triggering mechanism 101 includes a first swing arm 11. The first swing arm 11 is rotatably connected to the bottom of the mating moving plate 5 through a rotating shaft. A triggering tube 17 is fixedly connected to the bottom of the first swing arm 11. The bottom of the triggering tube 17 is rotatably connected to a second swing arm 13 through a rotating shaft. A counterweight 14 is rotatably connected to the bottom of the second swing arm 13. The counterweight 14 is made of iron and has a large density. It should be noted that when the first swing arm 11 and the second swing arm 13 shake, their swinging directions are towards two directions, one close to the mating box 3 and the other away from the mating box 3. A plurality of abutting boxes 19 are arranged inside the triggering tube 17. Each abutting box 19 is filled with a water-ethylene glycol mixture. When the water-ethylene glycol mixture is heated to 80 °C, the solution will expand due to thermal expansion and contraction. Two sliding columns are fixedly connected to one end of each abutting box 19 close to the triggering tube 17. Two first springs 20 are also fixedly connected between the abutting box 19 and the triggering tube 17. Each first spring 20 is sleeved on the outer wall of the corresponding sliding column. A mating shrinkage tube 21 is fixedly connected between every two sliding columns. The mating shrinkage tube 21 is made of rubber, and the rubber material has good elasticity and can be shrunk and reset multiple times. The mating shrinkage tube 21 is located outside the triggering tube 17. One end of the mating shrinkage tube 21 away from the sliding column is fixedly connected to an abutting block 15. A plurality of abutting blocks 15 are circumferentially distributed outside the triggering tube 17, and the outer wall of the abutting block 15 is arc-shaped; The first spring 20 can reset the abutting box 19. The opposite ends of all the abutting boxes 19 are arc-shaped surfaces. One end of each abutting box 19 away from the triggering tube 17 abuts against the outer wall of the corresponding limiting slide bar 6. Each mating shrinkage tube 21 is fixedly connected to the corresponding abutting box 19 through a pipeline; Please refer to Figures 4 to 8 As shown, the power-off mechanism 201 includes a mating arm 16. The mating arm 16 is fixedly connected to the bottom of the mating moving plate 5. A plurality of mating round rods 23 are fixedly connected to one end of the mating arm 16 close to the triggering tube 17. A first moving ring 24 with a reset function is slidably connected between the outer walls of all the mating round rods 23. A plurality of second springs 22 are fixedly connected between the first moving ring 24 and the mating arm 16. The second springs 22 are in a state of tensile energy storage. Each second spring 22 is sleeved on the outer wall of the corresponding mating round rod 23. When the first moving ring 24 is pulled and then loses the pulling force, the second spring 22 can drive the first moving ring 24 to quickly reset. A butting tube 12 is slidably connected between the outer walls of all the mating round rods 23. A third spring 28 is fixedly connected between the butting tube 12 and the mating round rod 23. The third spring 28 is sleeved on the outer wall of the mating round rod 23. The butting tube 12 is in a "funnel shape". The triggering tube 17 is located inside the butting tube 12. The butting tube 12 is located on the left side of the first moving ring 24. Please refer to Figure 7 , and a fixing ring 26 is also fixedly connected to the bottom of the mating arm 16; One end of the abutting pipe 12 close to the trigger pipe 17 is fixedly connected with a moving pipe 18 through a connecting rod 29. The connecting rod 29 is located outside the trigger pipe 17, and the moving pipe 18 is located on the left side of the trigger pipe 17. The moving pipe 18 is also in a "funnel shape". The outer wall diameter of the moving pipe 18 is smaller than the inner wall diameter of the trigger pipe 17. When the second moving ring 27 drives the third spring 28 to move towards the trigger pipe 17 through the connecting rod 29, when the moving pipe 18 moves to the inner wall of the trigger pipe 17, and when the outer walls of all the abutting boxes 19 are in contact with the inner wall of the moving pipe 18, since the funnel-shaped inner wall of the moving pipe 18 can abut and move all the abutting boxes 19, all the abutting boxes 19 will gather towards the opposite directions. When all the abutting boxes 19 gather towards the opposite directions, since the force of the abutting boxes 19 being squeezed will increase the friction between the abutting boxes 19 and the limiting slide rod 6, the overall movement of the trigger pipe 17 is restricted, which has a braking and limiting effect on the trigger pipe 17 and the cooperating moving plate 5, preventing the third spring 28 from continuing to move and generating vibrations that may damage the limiting slide rod 6 and the whole; A fixed ring 26 is fixedly connected to the bottom of the cooperating arm 16. The fixed ring 26 is located on the right side of the first moving ring 24. Multiple clamping arms 25 are fixedly connected to one end of the abutting pipe 12 close to the fixed ring 26. The multiple clamping arms 25 are circumferentially distributed on the outer wall of the abutting pipe 12. A plurality of bayonet openings 30 are also formed in the outer wall of the fixed ring 26. The plurality of bayonet openings 30 are circumferentially distributed on the outer wall of the cooperating arm 16. The outer wall of each clamping arm 25 is slidably connected to the inner wall of the corresponding bayonet opening 30. A sliding opening is formed in the inner part of the clamping arm 25. A cooperating clamping block 32 is slidably connected to the inside of each sliding opening. The cross section of the cooperating clamping block 32 is in a "triangle" shape. The cooperating clamping block 32 and the inner wall of the sliding opening are fixedly connected through a fourth spring 31. When the cooperating clamping block 32 is pressed to compress the fourth spring 31 to store energy, when the cooperating clamping block 32 loses the extrusion, the fourth spring 31 releases the stored energy to drive the cooperating clamping block 32 to quickly reset, and the outer wall of the cooperating clamping block 32 abuts against the outer wall of the second moving ring 27; Please refer to Figures 3 to 4As shown in the figure, a mating socket 9 is fixedly connected to one end of the mating moving plate 5 close to the mating arm 16. A connecting plate 33 is fixedly connected to the outer wall of the mating box 3 by bolts. The connecting plate 33 is located on the right side of the mating moving plate 5. A clamping plug 8 is inserted into the mating socket 9. A circuit is fixedly connected between the clamping plug 8 and the connecting plate 33. A shrinkage corrugated sleeve 7 is fixedly connected between the clamping plug 8 and the connecting plate 33. The shrinkage corrugated sleeve 7 is made of rubber material, and the rubber material has good corrosion resistance and high temperature resistance characteristics, and is durable. The circuit is arranged inside the shrinkage corrugated sleeve 7. The clamping plug 8 is fixedly connected to the second moving ring 27 through a connecting arm 10. When the abutting pipe 12 drives all the clamping arms 25 to move, the mating clamping block 32 will abut against the inner wall of the bayonet 30. The inclined surface of the mating clamping block 32 will abut against the inner wall of the bayonet 30, and the mating clamping block 32 will move towards the inner wall of the bayonet. When the second moving ring 27 loses the limit of the mating clamping block 32, the second spring 22 will drive the second moving ring 27 to move. The second moving ring 27 will drive the clamping plug 8 to disengage from the insertion inside the mating socket 9 through the connecting arm 10, so that the third spring 28 will quickly cut off the power, and the mating moving plate 5 will quickly stop moving.

[0031] The working principle of the present invention is: When the present invention is in use, after the third spring 28 is powered on, the third spring 28 will slide along the outer walls of the two limit slide bars 6. Since resonance will occur when the mating moving plate 5 and the third spring 28 move too fast during use, the mating moving plate 5 will damage the limit slide bars 6 when moving, and the outer walls of the limit slide bars 6 will be rubbed to generate high temperature during long-term movement. After a long time, the high temperature on the outer walls of the limit slide bars 6 will cause deformation; When the third spring 28 moves too fast or malfunctions and resonates, since the counterweight 14 is always vertically downward under the action of gravity, when it cooperates with the vibrating moving plate 5, the counterweight 14 will sway. The counterweight 14 drives the first swing arm 11, the trigger tube 17 and the second swing arm 13 to swing. When the swinging rate and amplitude are too large, the trigger tube 17 will sway. When the trigger tube 17 sways, it will abut against the inner wall of the abutting tube 12 and drive the abutting tube 12 to move. When the abutting tube 12 moves, it will drive all the clamping arms 25 to move. The clamping arms 25 will move into the bayonet 30. At this time, the cooperating clamping block 32 will abut against the inner wall of the bayonet 30. The inclined surface of the cooperating clamping block 32 will abut against the inner wall of the bayonet 30. The cooperating clamping block 32 will move towards the inner wall of the sliding port. When the second moving ring 27 loses the limit of the cooperating clamping block 32, the second spring 22 will drive the second moving ring 27 to move. The second moving ring 27 will drive the clamping plug 8 to disengage from the inner plug-in connection with the cooperating socket 9 through the connecting arm 10, so that the third spring 28 will quickly cut off the power, and the cooperating moving plate 5 will quickly stop moving. It should be noted that the contact area between the cooperating clamping block 32 and the second moving ring 27 is small, and the moving distance of the abutting tube 12 does not need to be too long to realize the disengagement of the cooperating clamping block 32 from the outer wall of the second moving ring 27; When the friction time between the limit slide bar 6 and the cooperating moving plate 5 is too long, resulting in too high a temperature, when the temperature reaches 80 degrees or above, the heat will conduct to the inside of the abutting box 19. At this time, the water-ethylene glycol mixture inside the abutting box 19 expands due to heat, and the cooperating shrinkage tube 21 will extend. The cooperating shrinkage tube 21 will drive the abutting block 15 to move. At this time, all the abutting blocks 15 will move in a motion that spreads outwards with the abutting box 19 as the center. All the abutting blocks 15 will exert a pushing force on the abutting tube 12. When the abutting tube 12 moves, according to the above working principle, the disengagement of the clamping plug 8 from the cooperating socket 9 can be completed. Using the principle of thermal expansion and contraction, an overheat automatic power-off protection is realized with a pure mechanical structure, without complex electronic components, effectively avoiding damage to equipment components and performance degradation caused by continuous high temperature, significantly improving the safety and reliability of the linear motor slide table operation, and being applicable to industrial automation scenarios with strict temperature control requirements. When the counterweight 14 and the upper connecting components sway together, when the swaying force is greater than the elastic coefficient of the first spring 20, the abutting tube 12 can be pushed; And when the clamping plug 8 is disengaged from the cooperating socket 9 and needs to be reset, when the water-ethylene glycol mixture cools down, only need to pull the second moving ring 27. When the second moving ring 27 moves, it will abut against the bottom of the cooperating clamping block 32. When the outer wall of the second moving ring 27 abuts against the outer wall of the cooperating clamping block 32, at this time, the cooperating clamping block 32 can limit the second moving ring 27. The second moving ring 27 drives the clamping plug 8 and the cooperating socket 9 to be plugged into each other, and then it can be used next time.

[0032] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
