Description

Technical Field

[0001] The invention relates to the technical field of tolerance laser detection, in particular to a tolerance laser detector for a shock absorber. Background Art

[0002] Shock absorbers, also known as dampers, absorb or dissipate vibration energy to reduce the impact of external vibration on products and prevent product damage. Shock absorbers are widely used in construction, bridges, automobiles, and mechanical equipment. During the production and processing of shock absorbers, tolerance laser detectors are required to detect the dimensions of piston rods, cylinders, and later assembled shock absorbers to determine whether the dimensions of the shock absorber and its components are within the tolerance range, thereby ensuring the accuracy and performance of the shock absorber during manufacturing or use. Since laser detectors are non-contact measurement, they do not touch the surface of the measured part to avoid damage, making them particularly suitable for the inspection of precision shock absorber components. For example, the patent name disclosed in the prior art with the announcement number "CN207779354U" is "An Intelligent Detector for Form and Position Tolerance of Insulators", which discloses turning on the laser light source, and at the same time the control console controls the motor to work, thereby driving the turntable to rotate, the laser light source will irradiate the rotating insulator, the parallelism formed by the rotation of the insulator will be imaged on the parallelism imaging processor, and the parallelism imaging processor will collect data at the same time, and the coaxiality formed will be imaged on the coaxiality imaging processor, and the coaxiality imaging processor will collect data. The insulator form and position tolerance data collected by the parallelism imaging processor and the coaxiality imaging processor will be transmitted to the data processing device, thereby performing data conversion processing on the insulator form and position tolerance, making the detection result more accurate, and the prior art with the announcement number "CN119 The patent disclosed in Patent No. 043165A is titled "A Laser Testing Platform for Automotive Shock Absorbers." It discloses that before a hydraulic cylinder pulls a piston rod to move, four groups of laser emitters and laser receivers are arranged in the east, west, south, and north directions, forming four regions: southeast, northeast, southwest, and northwest. Each group of laser emitters emits laser light in a straight line, which is received by the same group of laser receivers. The linear laser light is arranged in the tangent direction of the piston rod. The four adjacent laser groups are perpendicular to each other and are located in the four tangent points of the piston rod: east, west, south, and north. When the hydraulic cylinder pulls the piston rod to move, if the piston rod deflects, the laser light is blocked by the deflected piston rod. If the piston rod moves in a straight line normally, the laser light is not blocked. This allows the determination of whether the piston rod deflects during reciprocating motion, and further the determination of whether the shock absorber being tested is properly installed.

[0003] When the above-mentioned tolerance laser detector for shock absorbers in the prior art is in use, since the laser emitter and the laser receiver are limited by the position adjustment range, the laser detector can only detect whether the piston rod is deflected during movement, and cannot meet other detection requirements, which makes the applicability of the tolerance laser detector poor. Therefore, we propose a tolerance laser detector for shock absorbers to solve the problems raised above. Summary of the Invention

[0015] Compared with the existing technology, the present invention has the following beneficial effects: the shock absorber tolerance laser detector can detect the inner diameter size, inner diameter surface quality and cylindricity of the shock absorber cylinder, and can detect the diameter, surface roughness and cylindricity of the shock absorber piston rod. It can meet different testing requirements, significantly reduce the outflow of defective products, and improve the applicability of the tolerance laser detector. The specific contents are as follows: (1) By inserting the first laser distance measuring mechanism and the second laser distance measuring mechanism, which are arranged opposite to each other, into one end of the shock absorber cylinder, the inner diameter of the shock absorber cylinder can be detected to determine whether the inner diameter of the shock absorber cylinder is within the tolerance range and whether it meets the production and processing requirements; Furthermore, through the cooperation of the first threaded rod and the rotating rod, the mounting plate drives the shock absorber cylinder to rise and rotate at the same time, thereby detecting the inner diameter surface quality and cylindricity of the shock absorber cylinder, thereby meeting different detection requirements.

[0017] (3) When the entire tolerance laser detector is not in use, the support frame is lowered by a manual telescopic rod, which not only reduces the height of the entire tolerance laser detector and reduces the occupied area, making it easier to carry and transport the tolerance laser detector in the future, but also allows the lower end of the left support block and the lower end of the connecting block to be inserted into the protective tube, and then the protective tube cooperates with the inflatable airbag to shield and protect the outer sides of the first laser ranging mechanism and the second laser ranging mechanism, so as to prevent external dust from adhering to the surface of the first laser ranging mechanism and the second laser ranging mechanism when in use, thereby affecting the accuracy of subsequent detection.

[0021] See also Figures 1-11 , the present invention provides the following technical solutions: Example 1: The shock absorber tolerance laser detector in this embodiment can meet different detection requirements, thereby making the tolerance laser detector more applicable. For the specific structure, please refer to the attached Figure 1-Figure 7 And attached Figure 9-10 As shown, it includes a testing platform 1, and manual telescopic rods 2 symmetrically installed on the left and right sides above it, and the upper ends of the manual telescopic rods 2 are connected to the supporting frame 3. A mounting plate 4 is provided in the middle position of the upper surface of the testing platform 1, and a support ring plate 5 is rotatably installed on the outer side of the mounting plate 4, and four groups of clamping mechanisms 9 are connected to the upper interior of the mounting plate 4. A first threaded rod 6 is symmetrically installed on the front and back of the upper surface of the testing platform 1, and the outer side of the first threaded rod 6 is threadedly connected to the support ring plate 5. The interior of the supporting frame 3 is installed with a left support block 7 and a right support block 8 through a direction finding adjustment component, and a first laser ranging mechanism 71 is installed in the arc surface below the left support block 7, and the lower side of the right support block 8 is connected to the connecting block 81 through an electric push rod 82, and a second laser ranging mechanism 83 is installed in the arc surface below the connecting block 81.

[0022] Four groups of second threaded rods 91 are installed at equal intervals inside the mounting plate 4, and the inner ends of the four groups of second threaded rods 91 are connected by a bevel gear set, and the outer end of one of the second threaded rods 91 passes through the outer side surface of the mounting plate 4, and the outer side of the second threaded rod 91 is threadedly connected to the clamping mechanism 9, and the lower ends of the two first threaded rods 6 are connected by a sprocket assembly. The left support block 7, the right support block 8 and the connecting block 81 are all semicircular, and the left support block 7 fits tightly with the right support block 8 and the connecting block 81. The left support block 7 and the connecting block 81 are symmetrically arranged about the vertical center line of the mounting plate 4. The direction measurement adjustment assembly includes a bidirectional screw rod 12 installed in a groove opened on the bottom surface of the carrier frame 3. The right end of the bidirectional screw rod 12 passes through the right side surface of the carrier frame 3, and the outer side of the bidirectional screw rod 12 is threadedly connected to two adjustment The node block 13 and the adjusting block 13 are rotatably installed at the bottom of the connecting rod 15, and the outer key of the upper vertical end of the connecting rod 15 is connected to the transmission gear 16. The lower vertical end of one connecting rod 15 is connected to the top of the left support block 7, and the lower vertical end of the other connecting rod 15 is connected to the top of the right support block 8. Two rack assemblies 14 are symmetrically installed on the lower surface of the rear side of the carrier 3, and the front side of the rack assembly 14 is meshed with the transmission gear 16. The bottom surface of the mounting plate 4 is rotatably connected to the self-rotating rod 11, and the outer side of the upper end of the self-rotating rod 11 is nested and connected with a vortex spring 111, and one end of the vortex spring 111 is connected to the support ring plate 5, and the lower outer side of the self-rotating rod 11 is wrapped with a self-control rope 112, and the lower end of the self-control rope 112 is connected to the detection table 1 through a guide wheel.

[0023] First, when it is necessary to test the inner diameter of the shock absorber cylinder, one end of the shock absorber cylinder is placed in the middle position above the mounting plate 4. At this time, since the inner diameter of the shock absorber cylinder is larger than the diameter of the protective tube 10, the protective tube 10 is inserted into the shock absorber cylinder. Then, one end of one of the second threaded rods 91 is manually rotated. When the second threaded rod 91 rotates, the other three second threaded rods 91 can be driven to rotate together through the outer bevel gear set. Therefore, the four second threaded rods 91 rotate together. When the four second threaded rods 91 rotate, the clamping mechanism 9 connected to the outer thread moves inward, so that the cooperation of the four groups of clamping mechanisms 9 clamps and fixes one end of the shock absorber cylinder. Then, the servo motor in the testing platform 1 is started, and the servo motor drives one of the first threaded rods 6 to rotate. Since the lower ends of the two first threaded rods 6 are connected by a sprocket assembly, the two first threaded rods 6 rotate at the same time. When the first threaded rod 6 rotates, it drives the support ring plate 5 connected to the outer thread to rise, and the support ring plate 5 drives the mounting plate 4 to move upward, as shown in the attached figure. Figure 7As shown, when the mounting plate 4 drives the shock absorber cylinder to a certain height position, the lower ends of the tightly fitting left support block 7 and connecting block 81 will be inserted into the upper end of the shock absorber cylinder, so that the first laser ranging mechanism 71 and the second laser ranging mechanism 83 are arranged back to back and inserted into the upper end of the shock absorber cylinder. At this time, the first laser ranging mechanism 71 detects the distance between the left side surface of the left support block 7 and the left inner wall of the shock absorber cylinder. The distance value at this time is D1. The second laser ranging mechanism 83 detects the distance between the right side surface of the connecting block 81 and the right inner wall of the shock absorber cylinder. The distance value at this time is D2. The radii of the left support block 7 and the connecting block 81 are both D3. Then, it can be known that the inner diameter of the shock absorber cylinder is D=D1+D2+D3+D3, and then the inner diameter size of the shock absorber cylinder can be detected to determine whether the inner diameter size of the shock absorber cylinder is within the tolerance range and whether it meets the production and processing requirements.

[0024] At the same time, when the mounting plate 4 rises, the lower end of the self-control rope 112 is pulled, causing the self-control rope 112 to automatically drive the rotation rod 11 to rotate, and the vortex spring 111 begins to accumulate force, and the vortex spring 111 drives the mounting plate 4 to rotate together, so that the mounting plate 4 rotates in the support ring plate 5, and then the mounting plate 4 drives the shock absorber cylinder to rise and rotate at the same time, thereby allowing the first laser ranging mechanism 71 and the second laser ranging mechanism 83 to measure the inner diameters of different positions in the shock absorber cylinder. If the inner diameter values ​​at different positions are the same, it means that the inner diameter surface of the shock absorber cylinder is smooth and the cylindricity meets the standard. If the inner diameter values ​​at different positions are different, it means that the inner diameter surface of the shock absorber cylinder is rough and the cylindricity does not meet the standard.

[0025] When the diameter of the shock absorber piston rod needs to be tested, Figure 9-10As shown, first manually rotate the bidirectional screw rod 12, or use a motor to drive the bidirectional screw rod 12 to rotate. When the bidirectional screw rod 12 rotates, it drives the two adjustment blocks 13 connected by the outer thread to move outward at the same time. Then the two adjustment blocks 13 respectively drive the left support block 7 and the right support block 8 to move outward through the two connecting rods 15, so that the left support block 7 and the right support block 8 are separated. When the connecting rod 15 moves to a certain position, the transmission gear 16 on the outer side of the connecting rod 15 is engaged with the rack assembly 14, so that the transmission gear 16 drives the connecting rod 15 to rotate 180 degrees, and then One of the connecting rods 15 drives the left supporting block 7 and the first laser ranging mechanism 71 to rotate 180°, and the other connecting rod 15 drives the right supporting block 8, the connecting block 81, the electric push rod 82 and the second laser ranging mechanism 83 to rotate 180° together, so that the first laser ranging mechanism 71 and the second laser ranging mechanism 83 are arranged opposite to each other, and the electric push rod 82 is started at the same time, so that the electric push rod 82 drives the connecting block 81 and the second laser ranging mechanism 83 to move upward, so that the second laser ranging mechanism 83 and the first laser ranging mechanism 71 are not on the same horizontal plane.

[0026] Then place one end of the shock absorber piston rod on the protective cylinder 10 in the middle position above the mounting plate 4, and manually rotate one end of one of the second threaded rods 91. Similarly, as shown above, the operating steps are the same and therefore will not be repeated in detail, so that the cooperation of the four clamping mechanisms 9 clamps and fixes one end of the shock absorber piston rod. Then start the servo motor in the detection platform 1, and the servo motor drives one of the first threaded rods 6 to rotate. When the first threaded rod 6 rotates, it drives the supporting ring plate 5 and the mounting plate 4 to move upward. When the mounting plate 4 drives the shock absorber piston rod to a certain height position, the first laser measuring The distance mechanism 71 detects the distance between the right side of the left support block 7 and the left side of the shock absorber piston rod. The distance value at this time is L1. The second laser ranging mechanism 83 detects the distance between the left side of the connecting block 81 and the right side of the left support block 7. The distance value at this time is L2. Since the left support block 7 and the connecting block 81 are symmetrically arranged about the vertical center line of the mounting plate 4, it can be known that the diameter of the shock absorber piston rod is L=L2-L1-L1. Then, the diameter size of the shock absorber piston rod can be detected to determine whether the diameter size of the shock absorber piston rod is within the tolerance range and whether it meets the production and processing requirements.

[0027] At the same time, as shown above, the mounting plate 4 drives the shock absorber piston rod to rise and rotate at the same time, thereby allowing the first laser ranging mechanism 71 and the second laser ranging mechanism 83 to measure the diameters of the shock absorber piston rod at different positions. If the diameter values ​​at different positions are the same, it means that the diameter surface of the shock absorber piston rod is smooth and the cylindricity meets the standard. If the diameter values ​​at different positions are different, it means that the diameter surface of the shock absorber piston rod is rough and the cylindricity does not meet the standard. This can meet different detection requirements and significantly reduce the outflow of defective products.

[0028] Embodiment 2: The shock absorber tolerance laser detector in this embodiment is convenient for carrying and transporting the tolerance laser detector when not in use, and is also convenient for protecting the first laser distance measuring mechanism 71 and the second laser distance measuring mechanism 83. For specific structure, please refer to the attached Figures 8-11 As shown, a protective cylinder 10 is installed in the middle position above the mounting plate 4, and a cover plate 17 connected to the return spring 171 inside the protective cylinder 10 is fitted on the upper inner wall thereof, and an air storage bag 18 is installed inside the bottom surface of the protective cylinder 10. An expansion bag 182 is embedded in a groove on the upper inner wall of the protective cylinder 10, and a connecting pipe 181 is symmetrically installed on the bottom surface of the air storage bag 18. One end of the connecting pipe 181 passes through the side wall of the protective cylinder 10 and is connected to the expansion bag 182. The upper end diameter of the protective cylinder 10 is larger than the lower end diameter of the protective cylinder 10, and half of the lower end diameter of the protective cylinder 10 is larger than the radius of the left support block 7. The cover plate 17 forms a lifting structure through the left support block 7, and the air storage bag 18 is arranged in a circular shape.

[0029] On the basis of the first embodiment, when the entire tolerance laser detector is as shown in the attached Figure 1After the use shown is over, the locking mechanism of the manual telescopic rod 2 is manually unlocked (since the manual telescopic rod 2 is a prior art, it will not be described in detail here). The manual telescopic rod 2 is manually controlled to drive the carrier 3 to descend, so that the carrier 3 drives the left support block 7 and the right support block 8 to descend together, and then the lower ends of the left support block 7 and the connecting block 81 contact the cover plate 17 and apply a downward thrust. At this time, the return spring 171 accumulates force, and when the cover plate 17 descends to contact the air storage bag 18, the air storage bag 18 is squeezed, and the gas in the air storage bag 18 enters the ring-shaped expansion bag 182 through the connecting pipe 181, so that the volume of the expansion bag 182 expands inward, and then the inner side of the expansion bag 182 is tightly attached to the cover plate 17. The outer side surfaces of the left support block 7 and the connecting block 81 are in close contact with each other to prevent external dust from entering the protective tube 10, so that the first laser ranging mechanism 71 and the second laser ranging mechanism 83 are well placed in the protective tube 10, which is convenient for shielding and protecting the first laser ranging mechanism 71 and the second laser ranging mechanism 83, and prevents external dust from adhering to the surface of the first laser ranging mechanism 71 and the second laser ranging mechanism 83 when in use and affecting the subsequent detection accuracy. Then manually lock the locking mechanism of the manual telescopic rod 2 to fix the height position of the carrier frame 3 after it is lowered. Then the height of the entire tolerance laser detector is low, which makes it easy to carry and transport the tolerance laser detector to meet different needs, thereby completing a series of tasks.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
