A laser measuring device for porcelain insulators and a measuring method thereof

Abstract

This invention discloses a laser measuring device and method for porcelain insulators, including a base and a rotating transposition component on a support plate, relating to the field of insulator measurement technology. By using the rotating transposition component, the extension of a telescopic cylinder moves the traction plate upwards. At this time, the insert block moves towards the center of the top plate due to the pressure and guidance of the inclined guide rail on the locking pin, thereby bringing the clamping roller into contact with the porcelain insulator. The telescopic cylinder continues to extend, causing the traction plate to move relative to the disc. Simultaneously, the second telescopic spring extends. When the telescopic cylinder is fully extended, the positioning unit operates, and the horizontal movement of the laser measuring instrument detects the height of the porcelain insulator. When the porcelain insulator reaches a horizontal position, the laser beam emitted by the laser measuring instrument passes through the gap between adjacent clamping rollers and irradiates the outer side of the porcelain insulator, thus measuring the diameter of the porcelain insulator, enabling omnidirectional measurement of the porcelain insulator.

Description

Technical Field

[0001] This invention relates to the field of insulator measurement technology, specifically a laser measuring device and method for porcelain insulators. Background Technology

[0002] After the porcelain insulators are processed and formed, the dimensions of each insulator are inspected piece by piece using a laser rangefinder. After the inspection is completed, the porcelain insulators are rotated so that multiple porcelain insulators are connected in series. During the inspection operation, the insulators are driven to rotate and flip multiple times so that the laser beam emitted by the laser rangefinder can reach various points on the circumference of the skirt in sequence. Based on multiple sets of ranging data, the outer diameter and length of the porcelain insulators are measured over the entire range to determine whether the actual dimensions of the porcelain insulators meet the standards.

[0003] Generally, the position of the porcelain insulator needs to be repeatedly adjusted during the measurement process. This repeated adjustment can easily cause the initial positioning of the workpiece to deviate, the distance measurement reference of the laser rangefinder to become disordered, and the measured size data of the porcelain insulator to have a large error, resulting in poor measurement accuracy and easy misjudgment of size.

A second telescopic spring connected to the top of the disc is provided at the bottom of the traction plate. Positioning units are provided on both the support frame and the first piston cylinder.

[0008] As a further embodiment of the present invention: a second motor is provided at one end of the insert block, and the output end of the second motor is connected to the bottom of the clamping roller.

[0009] As a further embodiment of the present invention: the support frame has sliding grooves on both sides, and the L-shaped push rod is slidably connected to the support frame through the sliding grooves.

[0010] As a further embodiment of the present invention: the diameter of the slot is equal to the diameter of the top plate, the top of the T-shaped rod is rotatably connected to the bottom of the top plate by a bearing, and the bottom of the top plate is rotatably connected to a ball bearing by a rotating shaft.

[0011] As a further embodiment of the present invention: the positioning unit includes a second contact piece installed at the bottom of the T-shaped rod and located inside the first piston cylinder; a first solenoid valve is installed at the bottom end of the first piston cylinder; a U-shaped frame located outside the first solenoid valve is provided at the bottom of the first piston cylinder; the first contact piece is installed at the bottom end of the U-shaped frame; a third contact piece located below the second contact piece is provided on the inner wall of the first piston cylinder; a piston rod penetrating the L-shaped push rod is provided on one side of the support frame; a second piston cylinder connected to the L-shaped push rod is sleeved on the outside of the piston rod; a second solenoid valve is provided at the top of the second piston cylinder; and a fourth contact piece is installed at the top of the traction plate.

[0013] As a further aspect of the present invention: the maximum distance between the fourth contact piece and the first contact piece is equal to the maximum extension distance of the telescopic cylinder.

[0014] This invention also discloses a laser measurement method for porcelain insulators, which uses the aforementioned laser measurement device for porcelain insulators and includes the following steps: S1: First, place the porcelain insulator skirt to be measured upside down on top of the support plate, and press the porcelain insulator skirt so that the top of the porcelain insulator is flush with the top of the support plate. S2: The porcelain insulator is clamped and limited by the operation of the rotating transposition component. Then the laser measuring instrument is started. At this time, the laser beam emitted by the laser measuring instrument illuminates the center of the bottom of the porcelain insulator. Since the distance from the laser measuring instrument to the center axis of the rotating coupling is fixed, the length of the porcelain insulator can be obtained by subtracting the distance measured by the laser measuring instrument from the distance from the laser measuring instrument to the center axis of the rotating coupling. S3: The laser measuring instrument is moved horizontally by the linear module, so that the laser measuring instrument moves away from the bottom center of the porcelain insulator. During this process, the distance from the edge of the porcelain insulator skirt to the top of the porcelain insulator can be measured. S4: The operation of the first motor causes the rotating shaft to rotate the support plate 90 degrees, thereby turning the porcelain insulator to a horizontal position. At this time, the distance between the laser measuring instrument and the central axis of the rotating shaft remains unchanged. When the laser beam emitted by the laser measuring instrument shines on the side of the porcelain insulator, the diameter of the porcelain insulator can be obtained by subtracting the distance measured by the laser measuring instrument from the distance between the laser measuring instrument and the central axis of the rotating shaft. Similarly, the diameter of the porcelain insulator at different positions can be measured by the horizontal movement of the laser measuring instrument. In conjunction with the rotation of the rotating transposition component, the rotation of the porcelain insulator causes the laser beam emitted by the laser measuring instrument to shine on different positions of the porcelain insulator, thus allowing the diameter of the porcelain insulator at different positions to be measured.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting a rotary shifting component, the extension of the telescopic cylinder causes the traction plate to move upward. At this time, the traction plate, driven by the second telescopic spring, moves the disc upward synchronously. This causes the L-shaped push rod to push the inclined guide rail upward. The insert block, guided by the pressure of the inclined guide rail on the locking pin, moves towards the center of the top plate, thus bringing the clamping roller into contact with the porcelain insulator. The telescopic cylinder continues to extend, causing the traction plate to move relative to the disc. Simultaneously, the second telescopic spring extends. When the telescopic cylinder is fully extended, the positioning unit operates, and the positioning unit... The operation prevents the L-shaped push rod from moving relative to the support frame, and also prevents the top plate from moving relative to the support plate. Then, the height of the porcelain insulator is detected by the horizontal movement of the laser measuring instrument. When the porcelain insulator is rotated to a horizontal position, the laser beam emitted by the laser measuring instrument passes through the gap between the adjacent clamping rollers and irradiates the outside of the porcelain insulator, thus measuring the diameter of the porcelain insulator. During this process, the second motor is started, which drives the clamping rollers to rotate, thereby causing the clamping rollers to move the porcelain insulator to rotate, thus performing a full-range measurement of the porcelain insulator. 2. By setting up a positioning unit, when the L-shaped push rod moves relative to the support frame, the second piston cylinder moves along the piston rod. At this time, the air around the second piston cylinder will enter the inside of the second piston cylinder under pressure through the second solenoid valve. Similarly, when the top plate moves towards the support plate, the bottom of the T-shaped rod will compress the air inside the first piston cylinder. At this time, the air inside the first piston cylinder will be discharged from the first piston cylinder through the first solenoid valve. When the telescopic cylinder is fully extended, the first contact piece contacts the fourth contact piece. At this time, the first solenoid valve and the second solenoid valve are energized and closed. This makes the inside of the first piston cylinder closed, and at the same time, it makes the air inside the second piston cylinder lose its flow space. This can achieve the positioning of the top plate and the L-shaped push rod, so that the top plate cannot move relative to the support plate and the L-shaped push rod cannot move relative to the support frame. This can achieve the positioning of the porcelain insulator and prevent the porcelain insulator from moving relative to the support plate when rotating and repositioning the porcelain insulator, thereby avoiding data deviation caused by misalignment between the workpiece and the positioning device.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0020] Please see Figures 1 to 8 In this embodiment of the invention, a laser measuring device for porcelain insulators includes a base 1, a connecting frame 2 mounted on the top of the base 1, a linear module 4 disposed at the top of the connecting frame 2, a laser measuring instrument 5 connected to the bottom of the linear module 4, a first motor 3 mounted on one side of the connecting frame 2, a rotating shaft 8 connected to the connecting frame 2 disposed at the output end of the first motor 3, the rotating shaft 8 being rotatably connected to the connecting frame 2 via a bearing, a support plate 6 disposed at the end of the rotating shaft 8 away from the first motor 3, and a rotating transposition component disposed on the support plate 6; The central axis of the rotating coupling 8 is flush with the top of the tray 6, and the laser measuring instrument 5 is located directly above the tray 6.

[0021] In this embodiment: First, the porcelain insulator skirt to be measured is placed upside down on top of the support plate 6. The porcelain insulator skirt is pressed so that the top of the porcelain insulator is flush with the top of the support plate 6. At this time, the porcelain insulator is clamped and limited by the operation of the rotating transposition component. Then, the laser measuring instrument 5 is started. At this time, the laser beam emitted by the laser measuring instrument 5 illuminates the center of the bottom of the porcelain insulator. Since the distance from the laser measuring instrument 5 to the central axis of the rotating coupling 8 is fixed, the length of the porcelain insulator can be obtained by subtracting the distance measured by the laser measuring instrument 5 from the distance from the central axis of the rotating coupling 8. Then, the laser measuring instrument 5 is moved horizontally by the linear module 4 to move the laser measuring instrument 5 away from the center of the bottom of the porcelain insulator. During this process, the distance from the edge of the porcelain insulator skirt to the top of the porcelain insulator can be measured. Then, the operation of the first motor 3 is used to... The rotating coupling 8 drives the support plate 6 to rotate 90 degrees, thereby turning the porcelain insulator to a horizontal position. At this time, the distance between the laser measuring instrument 5 and the central axis of the rotating coupling 8 remains unchanged. When the laser beam emitted by the laser measuring instrument 5 shines on the side of the porcelain insulator, the diameter of the porcelain insulator can be obtained by subtracting the distance measured by the laser measuring instrument 5 from the distance between the laser measuring instrument 5 and the central axis of the rotating coupling 8. Similarly, the diameter of the porcelain insulator at different positions can be measured by the horizontal movement of the laser measuring instrument 5. In conjunction with the rotation of the rotating transposition component, the laser beam emitted by the laser measuring instrument 5 shines on different positions of the porcelain insulator, thus allowing for the measurement of the diameter at different positions of the porcelain insulator. This allows for all-round measurement of the porcelain insulator without affecting its installation and positioning. The operation is simple, improving both measurement efficiency and accuracy.

[0022] Please refer to this carefully. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6The rotary transposition component includes a slot 25 formed on the top of the pallet 6. Four guide frames 20 are mounted on the outer side of the pallet 6, and the four guide frames 20 are evenly distributed along the center of the pallet 6. A T-shaped rod 26 penetrating the pallet 6 is inserted into the inner side of the slot 25. A first piston cylinder 12 connected to the bottom of the pallet 6 is sleeved on the outer side of the T-shaped rod 26. A first telescopic spring 23 connected to the top of the inner wall of the first piston cylinder 12 is provided on the outer side of the T-shaped rod 26. An insert block 21 is inserted into the top of the guide frame 20. The top of the insert block 21 near the top plate 7 is rotatably connected to a clamping roller 19 via a bearing. The insert block 21 is away from the clamping roller 19. One end is provided with a locking pin 10, and an inclined guide rail 22 is sleeved on the outside of the locking pin 10. An L-shaped push rod 9 is provided at the bottom end of the inclined guide rail 22. A disc 34 located below the support plate 6 is provided at one end of the L-shaped push rod 9. A support frame 24 is provided at the bottom of the guide frame 20. A telescopic cylinder 11 is installed at the bottom of the support frame 24. The extension end of the telescopic cylinder 11 passes through the disc 34. The output end of the telescopic cylinder 11 is connected to a traction plate 32 located above the disc 34. A second telescopic spring 33 connected to the top of the disc 34 is provided at the bottom of the traction plate 32. Positioning units are provided on both the support frame 24 and the first piston cylinder 12.

[0023] One end of the insert block 21 is equipped with a second motor 18, the output end of the second motor 18 is connected to the bottom of the clamping roller 19, the two sides of the support frame 24 are provided with sliding grooves 29, the L-shaped push rod 9 is slidably connected to the support frame 24 through the sliding grooves 29, the diameter of the slot 25 is equal to the diameter of the top plate 7, the top of the T-shaped rod 26 is rotatably connected to the bottom of the top plate 7 through a bearing, and the bottom of the top plate 7 is rotatably connected to a ball bearing through a rotating shaft.

[0024] In this embodiment: When the porcelain insulator is placed upside down on top of the support plate 6, the top of the porcelain insulator is in contact with the top of the top plate 7. Then, the skirt of the porcelain insulator is pressed, causing the top plate 7 to move downward relative to the support plate 6. This causes the T-shaped rod 26 to move downward relative to the first piston cylinder 12, making the top of the top plate 7 flush with the top of the support plate 6. At this point, the porcelain insulator cannot move further downward. When the porcelain insulator cannot move downward, the telescopic cylinder 11 is activated. The extension of the telescopic cylinder 11 causes the traction plate 32 to move upward. At this time, the traction plate 32 will drive the disc 34 to move upward synchronously through the second telescopic spring 33. This allows the L-shaped push rod 9 to push the inclined guide rail 22 upward. At this time, the insert block 21 moves towards the center of the top plate 7 due to the squeezing and guiding of the clamping pin 10 by the inclined guide rail 22, so that the clamping roller 19 contacts the porcelain insulator. As the cylinder 11 continues to extend, the traction plate 32 moves relative to the disc 34, and the second telescopic spring 33 extends. When the cylinder 11 is fully extended, the positioning unit operates, preventing the L-shaped push rod 9 from moving relative to the support frame 24 and the top plate 7 from moving relative to the support plate 6. Then, the height of the porcelain insulator is detected by the horizontal movement of the laser measuring instrument 5. When the porcelain insulator is rotated to a horizontal position, the laser beam emitted by the laser measuring instrument 5 passes through the gap between the adjacent clamping rollers 19 and irradiates the outside of the porcelain insulator, thus measuring the diameter of the porcelain insulator. During this process, the second motor 18 is started, which drives the clamping rollers 19 to rotate, thereby rotating the porcelain insulator and measuring it from all angles.

[0025] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The positioning unit includes a second contact piece 27 installed at the bottom of the T-shaped rod 26 and located inside the first piston cylinder 12. A first solenoid valve 13 is installed at the bottom of the first piston cylinder 12. A U-shaped frame 14 is provided at the bottom of the first piston cylinder 12 and located outside the first solenoid valve 13. A first contact piece 15 is installed at the bottom of the U-shaped frame 14. A third contact piece 28 is provided on the inner wall of the first piston cylinder 12 and located below the second contact piece 27. A piston rod 30 penetrating the L-shaped push rod 9 is provided on one side of the support frame 24. A second piston cylinder 16 connected to the L-shaped push rod 9 is sleeved on the outside of the piston rod 30. A second solenoid valve 17 is provided at the top of the second piston cylinder 16. A fourth contact piece 31 is installed at the top of the traction plate 32.

[0026] The second contact 27 is electrically connected to an external power supply via a wire. The third contact 28 is electrically connected to the first contact 15, and the fourth contact 31 is electrically connected to the second solenoid valve 17 via wires. The second solenoid valve 17 and the first solenoid valve 13 are connected in series via wires. The maximum distance between the fourth contact 31 and the first contact 15 is equal to the maximum extension distance of the telescopic cylinder 11.

[0027] In this embodiment: when the L-shaped push rod 9 moves relative to the support frame 24, the second piston cylinder 16 moves along the piston rod 30. At this time, the air around the second piston cylinder 16 will enter the inside of the second piston cylinder 16 under pressure through the second solenoid valve 17. Similarly, when the top plate 7 moves towards the support plate 6, the bottom of the T-shaped rod 26 will compress the air inside the first piston cylinder 12. At this time, the air inside the first piston cylinder 12 will be discharged from the first piston cylinder 12 through the first solenoid valve 13. When the telescopic cylinder 11 is fully extended, the first contact piece 15 contacts the fourth contact piece 31. When the first solenoid valve 13 and the second solenoid valve 17 are energized and closed, the interior of the first piston cylinder 12 is sealed, and the air inside the second piston cylinder 16 is deprived of its flow space. This allows for the positioning of the top plate 7 and the L-shaped push rod 9, preventing the top plate 7 from moving relative to the support plate 6 and the L-shaped push rod 9 from moving relative to the support frame 24. This also enables the positioning of the porcelain insulator, preventing the porcelain insulator from moving relative to the support plate 6 during rotation and repositioning, thus avoiding data deviations caused by misalignment between the workpiece and the positioning device.

[0028] The following describes a laser measurement method for porcelain insulators, based on the aforementioned laser measuring device, specifically including the following steps: S1: First, place the porcelain insulator skirt to be measured upside down on top of the support plate 6, press the porcelain insulator skirt to make the top plate 7 move down relative to the support plate 6, thereby making the T-shaped rod 26 move down relative to the first piston cylinder 12, so that the top of the top plate 7 is flush with the top of the support plate 6, at which point the porcelain insulator cannot move down further. S2: Activate the telescopic cylinder 11. The extension of the telescopic cylinder 11 causes the traction plate 32 to move upward. At this time, the traction plate 32 will drive the disc 34 to move upward synchronously through the second telescopic spring 33. This allows the L-shaped push rod 9 to push the inclined guide rail 22 upward. At this time, the insert block 21 moves towards the center of the top plate 7 due to the squeezing and guiding of the locking pin 10 by the inclined guide rail 22, so that the clamping roller 19 contacts the porcelain insulator. The telescopic cylinder 11 continues to extend, and the traction plate 32 moves relative to the disc 34. Simultaneously, the second telescopic spring 33 extends. When the L-shaped push rod 9 moves relative to the support frame 24, the second piston cylinder 16 moves along the piston rod 30. At this time, the air around the second piston cylinder 16 will enter the inside of the second piston cylinder 16 under pressure through the second solenoid valve 17. Similarly, when the top plate 7 moves towards the support plate 6, the bottom of the T-shaped rod 26 will compress the air inside the first piston cylinder 12. At this time, the air inside the first piston cylinder 12 will be discharged from the first piston cylinder 12 through the first solenoid valve 13. When the telescopic cylinder 11 is fully extended, the first contact piece 15 contacts the fourth contact piece 31. At this time, the first solenoid valve 13 and the second solenoid valve 17 are energized and closed, thus sealing the interior of the first piston cylinder 12 and depriving the air inside the second piston cylinder 16 of its flow space. This allows for the positioning of the top plate 7 and the L-shaped push rod 9, preventing the top plate 7 from moving relative to the support plate 6 and the L-shaped push rod 9 from moving relative to the support frame 24. This also enables the positioning of the porcelain insulator, preventing the porcelain insulator from moving relative to the support plate 6 during rotation and repositioning, thereby avoiding data deviations caused by misalignment between the workpiece and the positioning device. Furthermore, the top plate 7 cannot move relative to the support plate 6. Then, the height of the porcelain insulator is detected by the horizontal movement of the laser measuring instrument 5. Since the distance from the laser measuring instrument 5 to the central axis of the rotating shaft 8 is fixed, the length of the porcelain insulator can be obtained by subtracting the distance measured by the laser measuring instrument 5 from the distance from the laser measuring instrument 5 to the central axis of the rotating shaft 8. S3: The laser measuring instrument 5 is moved horizontally by the linear module 4, so that the laser measuring instrument 5 moves away from the bottom center of the porcelain insulator. During this process, the distance from the edge of the shed of the porcelain insulator to the top of the porcelain insulator can be measured. S4: The operation of the first motor 3 causes the rotating shaft 8 to rotate the support plate 6 by 90 degrees, thereby turning the porcelain insulator to a horizontal position. At this time, the distance between the laser measuring instrument 5 and the central axis of the rotating shaft 8 remains unchanged. When the laser beam emitted by the laser measuring instrument 5 irradiates the side of the porcelain insulator, the diameter of the porcelain insulator can be obtained by subtracting the distance measured by the laser measuring instrument 5 from the distance between the laser measuring instrument 5 and the central axis of the rotating shaft 8. Similarly, the diameter of the porcelain insulator at different positions can be measured by the horizontal movement of the laser measuring instrument 5. In conjunction with the rotation of the rotating transposition component, the laser beam emitted by the laser measuring instrument 5 irradiates different positions of the porcelain insulator, thus allowing the diameter of the porcelain insulator at different positions to be measured.

10. A laser measurement method for porcelain insulators, characterized in that, The laser measuring device for porcelain insulators according to any one of claims 1-9 includes the following steps: S1: First, place the porcelain insulator skirt to be measured upside down on the top of the support plate (6), and press the porcelain insulator skirt so that the top of the porcelain insulator is flush with the top of the support plate (6). S2: The porcelain insulator is clamped and limited by the operation of the rotating transposition component. Then the laser measuring instrument (5) is started. At this time, the laser beam emitted by the laser measuring instrument (5) illuminates the center of the bottom of the porcelain insulator. Since the distance from the laser measuring instrument (5) to the central axis of the rotating shaft (8) is fixed, the length of the porcelain insulator can be obtained by subtracting the distance measured by the laser measuring instrument (5) from the distance from the laser measuring instrument (5) to the central axis of the rotating shaft (8). S3: The laser measuring instrument (5) is moved horizontally by the linear module (4) so ​​that the laser measuring instrument (5) moves away from the bottom center of the porcelain insulator. During this process, the distance from the edge of the porcelain insulator skirt to the top of the porcelain insulator can be measured. S4: The operation of the first motor (3) causes the rotating shaft (8) to rotate the tray (6) by 90 degrees, thereby turning the porcelain insulator to a horizontal state. At this time, the distance between the laser measuring instrument (5) and the central axis of the rotating shaft (8) remains unchanged. When the laser beam emitted by the laser measuring instrument (5) irradiates the side of the porcelain insulator, the diameter of the porcelain insulator can be obtained by subtracting the distance measured by the laser measuring instrument (5) from the distance between the laser measuring instrument (5) and the central axis of the rotating shaft (8). Similarly, the diameter of the porcelain insulator at different positions can be measured by the horizontal movement of the laser measuring instrument (5). The rotation of the porcelain insulator is driven by the rotating transposition component to make the laser beam emitted by the laser measuring instrument (5) irradiate different positions of the porcelain insulator. In this way, the diameter of the porcelain insulator at different positions can be measured.
