DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] See also Figure 1-10 A high-precision laser detection device for component size comprises a measuring table 1 and a laser diameter measuring instrument and a laser triangulation measuring instrument 2 arranged on the measuring table 1. A support block 21 for horizontally supporting cylindrical parts is rotatably arranged on the measuring table 1, two friction wheels 25 are slidably arranged on the support block 21, a positioning block 13 for driving the friction wheel 25 to rotate is rotatably arranged on the support block 21, and a cleaning component is arranged on the measuring table 1; a driving component comprises a moving plate 56 slidably arranged on the measuring table 1, and also comprises a positioning block 13 rotatably arranged on the support block 21 for driving the friction wheel 25 to rotate, a placing plate 57 and a rotating rod 54 are slidably arranged on the moving plate 56; when the moving plate 56 moves, it pushes the parts to complete the loading, and at the same time, the rotating rod 54 drives the friction wheel 25 to rotate to clamp the parts and rotate the parts to realize the cleaning of the peripheral surface and the end surface, and drives the supporting block 21 to flip after the diameter and ovality detection; the laser diameter measuring instrument comprises a laser transmitter 3 and a laser receiver 4 arranged on the measuring table 1, and the positional relationship between the laser diameter measuring instrument and the laser triangulation measuring instrument 2 is as shown in FIG. Figure 1As shown, the support block 21 is arranged on one side of the middle position between the laser transmitter 3 and the laser receiver 4. When using the laser diameter gauge to measure the diameter of the cylinder, the cylinder is generally laid down horizontally. At this time, the axis of the cylinder is parallel to the measuring platform, and the laser beam emitted by the laser diameter gauge can be scanned along the radial direction of the cylinder. If the cylinder is in a vertical state, when measuring the diameter from the side, due to the curvature of the cylindrical surface, the reflection and scattering of the laser beam will be more complicated, which may cause large errors for high-precision diameter measurement, and it is not as convenient as the horizontal laying state in operation. When using the laser triangulation measuring instrument 2 to measure the length of a cylindrical workpiece, the cylindrical workpiece is usually placed vertically. This is because when the cylinder is in a vertical state, its height direction is consistent with the direction of gravity, which is convenient for the laser beam to be vertically irradiated along the axial direction of the cylinder. In this way, the principle of laser triangulation can be directly used to calculate the height of the cylinder by measuring the change in the imaging position of the light reflected from the top and bottom of the cylinder on the detector. If the cylinder is in a horizontal position, the laser beam needs to be adjusted to a direction perpendicular to the axis of the cylinder to measure the height, which will increase the complexity of the measurement and may introduce more errors in positioning and ensuring the verticality of the measurement direction. Therefore, in order to ensure the high accuracy of the measuring equipment, the cylindrical parts need to be placed horizontally when using the laser diameter gauge to measure the diameter and ovality, and the cylindrical parts need to be placed vertically when measuring the length;There is a V-shaped groove in the middle of the support block 21. When the component moves onto the support block 21, the friction wheel 25 moves down and abuts against the surface of the component, thereby driving the cleaning component to abut against the surface of the component. The placement plate 57 is V-shaped. When the support block 21 is in a horizontal state, the V-groove of the placement plate 57 is aligned with the V-groove of the support block 21. The length of the placement plate 57 is shorter than the length of the cylindrical workpiece. In the initial state, the friction wheel 25 is lifted. When in use, the cylindrical workpiece is placed on the placement plate 57, and one end of the workpiece is abutted against the moving plate 56. At this time, the V-groove of the support block 21 can make the end face of the workpiece fit with the moving plate 56. The moving plate 56 is moved in the direction close to the support block 21, and the moving plate 56 drives the cylindrical workpiece and the rotating plate 56 to move. The rod 54 moves, and when the workpiece on the placement plate 57 moves away from one end of the movable plate 56 to the V-groove of the support block 21, the friction wheel 25 moves down and abuts against the top of the workpiece, thereby pressing the workpiece into the V-groove of the support block 21, and the cleaning component also abuts against the outer circumference of the workpiece at this time. As the movable plate 56 moves, the rotating rod 54 drives the friction wheel 25 to rotate, and the friction wheel 25 drives the cylindrical workpiece to rotate when it rotates, so that the outer circumference of the workpiece is cleaned by the cleaning component abutting against the workpiece. When the laser diameter gauge measures the diameter and ovality of the cylindrical workpiece, it can prevent stains and dust on the outer circumference of the workpiece from affecting the detection accuracy. At the same time, as the movable plate 56 pushes the workpiece to move, the cleaned part of the workpiece gradually extends into the laser emitter 3 and the laser receiver 4, at this time, the diameter of the workpiece can be detected, and the diameter of the workpiece can be detected at different positions as the workpiece moves to ensure the accuracy of the measurement. When the movable plate 56 is completely in contact with the support block 21, the end face of the cylindrical workpiece in contact with the movable plate 56 is also aligned with the side face of the support block 21. At this time, the movable plate 56 continues to be moved in the direction close to the support block 21, and the cylindrical workpiece will not move but only rotate. At this time, changing the laser emission mode of the laser diameter gauge can detect the ovality of the rotating workpiece, and the end face of the workpiece away from the movable plate 56 is cleaned while the workpiece rotates. When the placement plate 57 is in contact with the support block 21, the movable plate 56 continues to move, and the placement plate 57 is on the movable plate 5 6 slides in the direction away from the support block 21. When the ovality detection is completed, the moving plate 56 is moved in the direction away from the support block 21. When the moving plate 56 reaches the specified position, the support block 21 flips 90 degrees. When the support block 21 flips, the friction wheel 25 clamps the workpiece in the V-shaped groove of the support block 21 to ensure the stability of the workpiece during flipping. After the support block 21 flips 90 degrees, the side surface of the support block 21 and the end surface of the workpiece are both in contact with the detection table. At this time, the cylindrical workpiece changes from a horizontal state to a vertical state and is directly under the laser triangulation measuring instrument 2. At this time, the height (i.e., length) of the workpiece can be measured by the laser triangulation measuring instrument 2. When the workpiece height measurement is completed, the workpiece is removed to complete the measurement. ;

[0021] Specifically, the cleaning component includes a cleaning column 35 rotatably connected to the friction wheel 25, a V-block 6 is fixedly arranged on the measuring table 1, and a cleaning plate 7 is fixedly arranged on the side of the V-block 6 away from the support block 21; the V-block 6 and the support block 21 are symmetrically arranged on both sides of the laser measuring instrument, when the friction wheel 25 moves down and contacts the top surface of the workpiece, the cleaning column 35 also moves down and abuts against the top surface of the workpiece, at this time, the friction wheel 25 drives the workpiece to rotate, and the cleaning column 35 does not rotate, so that the circumference of the workpiece can be cleaned, and the accuracy of diameter and ovality measurement is increased. The cleaning column 35 is arranged on the side of the support block 21 away from the moving plate 56. When the moving plate 56 pushes the end face of the workpiece to be flush with the side wall of the support block 21, the other end of the workpiece is flush with the cleaning plate 7 When the workpiece is in contact with the cleaning plate 7, the workpiece will not move during rotation, and the ovality of the workpiece can be detected. At the same time, the end face of the workpiece in contact with the cleaning plate 7 is cleaned during rotation. After the support block 21 is flipped 90 degrees, the cleaned end face of the workpiece faces upward. When the laser of the laser triangulation measuring instrument 2 is irradiated to the top of the cylindrical workpiece, the stains and dust on the end face can be prevented from affecting the measurement accuracy. When the moving plate 56 pushes the workpiece to move a certain distance, one end of the workpiece will gradually move to the V-block 6 and finally abut against the cleaning plate 7 on the V-block 6. When the workpiece abuts against the cleaning plate 7, the diameter of the workpiece between the V-block 6 and the support block 21 is measured by a laser diameter gauge, and then the workpiece is only rotated to detect the ovality of the workpiece by the laser diameter gauge.

[0022] In another embodiment of the present invention, a push plate 51 is slidably arranged on the measuring table 1, L-shaped grooves 41 are provided on both sides of the support block 21, and a flip column 42 is slidably arranged in each L-shaped groove 41, and a fixed rod 50 is fixedly arranged on both sides of the push plate 51, and a movable sleeve 43 is fixedly arranged at one end of each fixed rod 50 away from the push plate 51, and each flip column 42 is slidably arranged in each movable sleeve 43 in a one-to-one corresponding manner; the long arm end of each L-shaped groove 41 is opened, such as Figure 2As shown, in the initial state, the support block 21 is in a vertical state, at this time, the short arm end of the L-shaped slot 41 is parallel to the measuring table 1, and the long arm end of the L-shaped slot 41 is perpendicular to the measuring table 1. At this time, the flip column 42 is at the end of the short arm end of the L-shaped slot 41, and the measuring table 1 is fixedly provided with a hydraulic cylinder 5, and the moving end of the hydraulic cylinder 5 is fixedly connected to the push plate 51. When it is necessary to measure the size of the cylindrical workpiece, the hydraulic cylinder 5 is started, and the hydraulic cylinder 5 pushes the push plate 51 to move in the direction close to the support block 21. When the push plate 51 moves, it drives the fixed rod 50 and the movable sleeve 43 to move, and when the movable sleeve 43 moves, it drives The flip column 42 moves, and when the flip column 42 moves to the turning point of the L-shaped groove 41, the push plate 51 continues to move. As the push plate 51 moves, the support block 21 is flipped 90 degrees through the abutment between the flip column 42 and the inner wall of the long arm end of the L-shaped groove 41, so that the support block 21 becomes horizontal. At this time, the hydraulic cylinder 5 is stopped, and the cylindrical workpiece is placed on the placement plate 57. Then, the hydraulic cylinder 5 is started again to push the push plate 51 to move the workpiece to the support block 21 in the horizontal state, thereby completing the loading. In the horizontal state, the support block 21 is rotatably connected to the measuring table 1 near the bottom edge of the moving plate 56.

[0023] Furthermore, a third spring 59 is fixedly provided between the push plate 51 and the movable plate 56, two cross bars 58 are fixedly provided on the side of the placement plate 57 close to the push plate 51, and two reset columns 11 are fixedly provided on the measuring table 1; when the push plate 51 moves, the movable plate 56 can be driven to move by the third spring 59, and the reset columns 11 are respectively arranged on the outer sides of the corresponding fixed rods 50, and the distance between the two reset columns 11 is greater than the width of the push plate 51. In the initial state, the flip column 42 is at the end of the short arm end of the L-shaped groove 41. At this time, the two cross plates abut against the corresponding reset columns 11, so that the placement plate 57 extends out from the side of the movable plate 56 away from the push plate 51. At this time, there is a certain distance between the end of the placement plate 57 away from the push plate 51 and the vertical support block 21, and the hydraulic cylinder 5 is started, and the push plate 51 moves in the direction close to the support block 21, and drives the movable plate 56 and the extended placement plate 57 moves. When the fixing rod 50 flips the support block 21 through the cooperation of the movable sleeve 43 and the flip column 42, the cylindrical workpiece is placed on the extended placement plate 57. As the push plate 51 drives the movable plate 56 to push one end of the workpiece onto the horizontal support block 21, the placement plate 57 gradually moves in the direction close to the push plate 51, and the workpiece gradually moves toward the support block 21. When the movable plate 56 and the support block 21 are fitted together, the placement plate 57 is completely retracted into the movable plate 56, and there is still a distance between the two cross plates and the push plate 51. When the diameter and ovality of the workpiece are measured and the end is cleaned, the hydraulic cylinder 5 is started to reset the push plate 51. At this time, the movable plate 56 is reset driven by the third spring 59. During the resetting process of the movable plate 56, the cross plate abuts against the reset column 11. As the push plate 51 moves, the placement plate 57 extends out from the movable plate 56 again and returns to the initial position.

[0024] Furthermore, a lifting plate 22 is slidably provided on the support block 21, two first springs 23 are fixedly provided between the lifting plate 22 and the support block 21, two fixed plates 24 are fixedly provided at the bottom of the lifting plate 22, one of the friction wheels 25 is rotatably provided between the two fixed plates 24, and the cleaning column 35 is rotatably provided on the side wall of one of the fixed plates 24; the lifting plate 22 slides up and down on the support block 21, and the lifting plate 22 always has a tendency to approach the support block 21 through the two first springs 23. When the support block 21 is flipped from the initial vertical state to the horizontal state, the lifting plate 22 is lifted, and at this time, there is a large distance between the friction wheel 25 and the V-groove of the support block 21, Thereby, cylindrical workpieces of different diameters can be placed. When one end of the cylindrical workpiece is pushed under the friction wheel 25, the lifting plate 22 is released, and the lifting plate 22 is made to fall by the two first springs 23, so that the friction wheel 25 can abut and clamp the cylindrical workpieces of different diameters. The cleaning column 35 is rotatably arranged on the side wall of the fixed plate 24 away from the movable plate 56. There is a large friction between the cleaning column 35 and the fixed plate 24. When the workpiece rotates, the abutment with the workpiece does not drive the cleaning column 35 to rotate, so that the peripheral surface of the workpiece can be better cleaned. After using it for a period of time, the cleaning column 35 is manually rotated to a certain angle, so that the utilization rate of different positions of the cleaning column 35 can be improved.

[0025] In another embodiment of the present invention: a support frame 30 is fixedly arranged on the support block 21, a first pulley 26 and a compensation wheel 28 are rotatably arranged in the support frame 30, a second pulley 27 is fixedly arranged between the two friction wheels 25, a transmission belt 29 is transmitted on the first pulley 26, the second pulley 27 and the compensation wheel 28, an alignment block 13 is rotatably arranged on the support frame 30, and the alignment block 13 is fixedly connected to the first pulley 26; the support frame 30 is fixedly arranged on a side of the lifting plate 22 close to the moving plate 56, one of the two friction wheels 25 extends from the side of the lifting plate 22 and is located below the support frame 30, when the end of the cylindrical workpiece on the placement plate 57 moves to a certain distance on the support block 21 in a horizontal state, The end of the rotating rod 54 abuts against the alignment block 13 to achieve interlocking. At this time, the rotating rod 54 no longer moves after abutting against the alignment block 13. As the moving plate 56 and the push plate 51 continue to move, the rotating rod 54 rotates, thereby driving the alignment block 13 to rotate. When the alignment block 13 rotates, it drives the first pulley 26 to rotate. When the first pulley 26 rotates, it drives the compensation wheel 28 and the second pulley 27 to rotate through the transmission belt 29, and then drives the two friction wheels 25 abutting against the circumferential surface of the workpiece to rotate, so that the workpiece rotates, realizing rotation and cleaning while the workpiece is loaded. The second pulley 27 is rotationally connected to one of the fixed plates 24, and the two friction wheels 25 are fixedly connected to the two sides of the second pulley 27 respectively.

[0026] Specifically, transverse grooves 301 are provided on both sides of the support frame 30, and a slider 31 is slidably arranged in each transverse groove 301. The compensation wheel 28 is rotatably arranged between the two sliders 31. A driving block 33 is fixedly arranged on the lifting plate 22, and a driving groove 34 is provided on the driving block 33. A driving rod 32 is slidably arranged in the driving groove 34, and the driving rod 32 is fixedly connected to one of the sliders 31. Since the lifting plate 22 drives the friction wheel 25 to fall, it can adapt to workpieces of different diameters. When the diameter of the workpiece is large, the height of the lifting plate 22 and the friction wheel 25 will become larger, and at this time the transmission belt 29 will become loose, and the lifting plate 22 can adapt to the workpieces of different diameters. Figure 6 and Fig.10 In the initial state, each slider 31 is on the right side of the transverse groove 301. At this time, the lifting plate 22 and the friction wheel 25 move downward to the limit. When the support block 21 flips from the vertical state to the horizontal state, the lifting plate 22 is lifted. At this time, the lifting plate 22, the friction wheel 25 and the driving block 33 move upward relative to the support frame 30, and the compensation wheel 28 moves to the left through the transverse groove 301, the driving groove 34, the slider 31 and the driving rod 32. When the lifting plate 22 is released, the lifting plate 22 moves downward through the first spring 23. When the lifting plate 22 moves downward, the driving plate and the friction wheel 25 also move downward, thereby driving the compensation wheel 28 to move rightward, so that the transmission belt 29 is always in a taut state, thereby ensuring that the first pulley 26 can drive the two friction wheels 25 to rotate when inspecting workpieces of different diameters.

[0027] Furthermore, a rotating plate 52 is fixedly provided on the push plate 51, a spiral groove is provided on the outer circumference of the rotating rod 54, a contact ball 53 adapted to the spiral groove is fixedly provided in the rotating plate 52, a plurality of alignment rods 55 are fixedly provided on one end of the rotating rod 54 close to the support block 21, a plurality of alignment holes 14 adapted to the alignment rods 55 are provided on the alignment block 13, and a reset plate 12 is fixedly provided on the measuring table 1; the rotating rod 54 can both slide on the top of the moving plate 56 and can rotate, such as Figure 4As shown, in the initial state, the rotating rod 54 is completely extended from the rotating plate 52, and the rotating rod 54 is driven to move together with the push plate 51 when it moves. When a part of the workpiece on the placement plate 57 moves to the support block 21 in the horizontal state, the placement plate 57 and the end thereof abut against the support block 21, and at this time, the end of the rotating rod 54 abuts against the alignment block 13, and as the push plate 51 moves, each alignment rod 55 is inserted into the corresponding alignment hole 14, and the rotating rod 54 cannot move with the push plate 51. When the push plate 51 continues to move, the rotating rod 54 rotates through the cooperation of the abutting ball 53 and the spiral groove, thereby driving the alignment block 13 to rotate, and then driving The first pulley 26 is driven to rotate, so that the friction wheel 25 also rotates. When the placement plate 57 is fully retracted into the moving plate 56, there is still a distance between the end of the placement plate 57 and the push plate 51. At this time, the push plate 51 continues to be moved toward the support block 21, and the third spring 59 is compressed. At this time, the workpiece no longer moves, but the cooperation between the abutment ball 53 and the spiral groove enables the rotating rod 54 to still rotate. When the rotating rod 54 rotates, the end away from the support block 21 will extend from the side of the rotating plate 52 away from the support block 21. When the push plate 51 moves back, the abutment between the rotating rod 54 and the reset can make the rotating rod 54 return to its initial position.

[0028] In another embodiment of the present invention: downward pressing rods 36 are fixedly arranged on both sides of the bottom of the lifting plate 22, two mounting plates 38 are fixedly arranged on the measuring table 1, and connecting rods 39 are slidably arranged on each mounting plate 38, and second springs 40 are fixedly arranged one by one between each connecting rod 39 and each mounting plate 38, and a moving frame 37 is fixedly arranged on one side of each connecting rod 39 close to the support block 21; the mounting plates 38 are located on both sides of the support block 21, and when the support block 21 is in a vertical state and the workpiece is removed, the first spring 23 drives the friction wheel 25 to move in the direction close to the support block 21, and when the push plate 51 pushes the support block 21 to flip through the fixed rod 50, the friction wheel 25 moves in the direction close to the support block 21. During the rotation process, the two lower pressure rods 36 on the lifting plate 22 respectively abut against the top end of the moving frame 37. As the support block 21 flips, the lifting plate 22 moves upward relative to the support frame 30 through the lower pressure rod 36. When the support block 21 is completely flipped into a horizontal state by the fixed rod 50, the space between the friction wheel 25 and the V-shaped groove of the support block 21 is completely opened. At this time, cylindrical workpieces of different diameters can be placed on the support table for inspection. None of the components on the support block 21 are exposed from the side of the support block 21 close to the moving plate 56. When the flip column 42 moves to the inflection point of the L-shaped groove 41, the placement plate 57 and the rotating rod 54 will not interfere with the rotation of the support block 21.

[0029] Specifically, two guide frames 46 are fixedly arranged on the measuring table 1, and each guide frame 46 has a guide groove 47, and each guide groove 47 includes an outer oblique portion 48. A moving rod 45 is slidably arranged in each guide groove 47, and a push rod 44 is slidably arranged on each flip column 42, and each push rod 44 is fixedly connected with each moving rod 45 in a one-to-one correspondence; when the support block 21 flips, the lifting plate 22 is lifted by the abutment between the lower pressure rod 36 and the top of the moving frame 37. When one end of the cylindrical workpiece on the placement plate 57 is pushed onto the support block 21, as the push plate 51 continues to move toward the direction close to the support block 21, the moving rod 45 enters the outer oblique portion 48 from one side of the outer oblique portion 48 of the guide groove 47, and the push rod 44 is moved outward by the guidance of the outer oblique portion 48, thereby moving each moving frame 37 away from the lower pressure rod 3 6, with the movement of the moving rod 45, each moving frame 37 is separated from the corresponding pressing rod 36, and at this time, the lifting plate 22 is moved down by the first spring 23. When the diameter and ovality detection of the workpiece are completed and the end is cleaned, the push plate 51 is driven to move back by the hydraulic cylinder 5, so that the fixed rod 50 drives the flip column 42 to move from the long arm end of the L-shaped groove 41 to the short arm end of the L-shaped groove 41, and the support block 21 is driven to flip through the flip column 42 at the intersection of the long arm end and the short arm end. When the support block 21 flips, the workpiece is clamped by the first spring 23, the friction wheel 25 and the V-shaped groove of the support block 21 to ensure that the workpiece will not be displaced when the support block 21 flips, so that the end of the workpiece fits with the measuring table 1, which is convenient for the laser triangulation measuring instrument 2 to measure the height of the workpiece, such as Figure 8 As shown, the push rod 44 slides in the guide frame 46. When the lower pressure rod 36 abuts against the top of the moving frame 37, the cooperation between the guide frame 46 and the push rod 44 causes the flip wheel to press down the long arm end of the L-shaped groove 41, thereby making the support block 21 fit the surface of the measuring table 1.

[0030] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
