Description

Technical Field

[0001] The invention relates to a spring cover detection device, in particular to a spring cover comprehensive detection device and a detection method thereof. Background Art

[0002] Inspection, from large mechanisms to small screws, all will be inspected before being packaged and shipped out of the factory. This is not only a quality control for the product itself, but also lays the foundation for the safety of the product in the later use. Shock absorbers are indispensable components in automotive parts. They are set at the corresponding position of the car's wheel hub to cushion the bumps when the car is driving. A spring cover for fixing and supporting the spring is required on the shock absorber to suppress the shock when the spring rebounds after absorbing the vibration of the road, as well as the bumps from the road, thereby limiting the spring to a certain area and maximizing the shock absorption effect. In order to give full play to its role, the outer contour size requirements of the spring cover are very precise.

[0003] There is no special equipment for spring cover inspection. However, in some disc-shaped inspection equipment, visual inspection is mostly used to inspect the spring cover. The difference between the spring cover to be inspected and the stored image is recorded by taking pictures, so as to identify whether the spring cover to be inspected has defects and the specific location of the defects.

[0004] However, existing online monitoring equipment can only detect specific defect locations. As for the form and position tolerances of the spring cover, it is difficult to detect and determine the specific gap location. Manual judgment and product model building are still required, and problems with the production equipment are determined based on the product errors. If some high-precision three-coordinate precision testing machines are introduced, they have high requirements for the testing environment and are difficult to establish a direct connection with the production line. A separate testing environment is required, which results in high transportation costs and equipment costs.

[0005] Therefore, this case aims to provide a comprehensive detection equipment and detection method for spring covers, which can monitor the inner diameter and outer circle of the spring cover, accurately establish the workpiece contour model through a large amount of data, and analyze and calculate the outer diameter size and the form and position tolerances such as the roundness and cylindricity of the workpiece outer circle through the data model. A complete data model can be established without manual judgment, and the parameters of the production equipment can be adjusted in time according to the model, thereby improving the product yield.

[0023] The present invention also provides a spring cover comprehensive detection method, which uses the above-mentioned spring cover comprehensive detection device, and specifically comprises the following steps:

[0024] S1: Use the flip structure to flip the bottom surface of the spring cover upward and fix it in the first fixture. After the spring cover is in place, the inner diameter detection component is rotated to the top of the spring cover. The outer ring detection structure and the inner ring detection structure in the inner diameter detection component perform pneumatic detection on both sides of the inner side of the spring cover respectively. The pneumatic detection data is transmitted back to the modeling structure;

[0027] S4: The spring cover with the inner diameter and outer circle inspected is turned over to the transfer table by the turning structure. The model after modeling that is consistent with the pre-drawn model is transferred to the qualified end by the turning structure. The model after modeling that is not consistent with the pre-drawn model is transferred to the unqualified end by the turning structure.

[0028] The beneficial effects of the present invention are:

[0029] The present invention establishes a complete set of comprehensive detection structures for spring covers. First, the inner diameter detection structure is used to detect the inner side of the spring cover, and a model of the inner side of the spring is established through the modeling structure. Then, the outer side of the spring cover is monitored through the outer circle detection structure, and a model of the outer side of the spring cover is established through the modeling structure, so that a complete three-dimensional model of the spring cover can be established. In the event that the spring cover has depressions, protrusions, horizontal lines, or inaccurate dimensions, these can be fully reflected, and the difference between the actual dimension and the processed dimension can be displayed, so that the user can accurately correct the production structure, improve the product yield, and quickly modify the equipment parameters.

[0030] During the inspection of the inner diameter of the spring cover, it needs to be in a fixed state, so the present invention utilizes a first fixture for clamping. Since it needs to be loaded upside down, the inner diameter detection component is not initially set above the first fixture, but is instead arranged in an eccentric manner. When needed, the rotating table is used to rotate the inner section detection structure to the position of the first fixture corresponding to the spring cover, and then the push rod motor is used to lower it to the corresponding position, so that the inner section detection structure is in a suspended state and does not directly contact the spring cover, thereby not causing the spring cover to shift during the inspection process. Each area of ​​the inner side of the spring cover can be accurately inspected one by one to avoid repeated inspections and missed inspections.

[0031] Since the spring cover is not simply an open cylindrical structure, it has multiple levels and other inner rings inside. Therefore, it is more difficult to detect the inner side of the spring cover. To this end, the present invention proposes to divide the inner surface detection structure into an outer ring detection structure and an inner ring detection structure, so that the detection can be carried out in different areas. When forming a model, the levels between each area can be more obvious, and the generated model is closer to the physical model.

[0032] However, due to the partitioned detection, there is a problem of different detection surfaces, so there are certain differences in the detection of the outer ring area and the inner ring area, that is, the detected wall surfaces are different. In this regard, the present invention first proposes an outer ring detection structure, and the first bottom pneumatic probe and the first lateral pneumatic probe on the outer ring detection structure perform detailed detection of the outer ring of the inner side of the spring cover, thereby forming two relatively complete model surfaces. Thereafter, the present invention also proposes an inner ring detection structure, which performs special detection on the inner ring of the three-sided structure, and adopts the second bottom pneumatic probe, the second lateral pneumatic probe and the third lateral pneumatic probe to form three relatively complete model surfaces. In the process of combining the inner ring detection structure with the outer ring detection structure, a complete inner model surface is formed.

[0033] However, if the detection is only performed through an inner section detection structure, the detected structure is only a flat surface structure, not a three-dimensional structure, and it is completely unable to fit the physical model. Therefore, the present invention introduces an outer circle detection part in the second processing area. In the process of detecting the outer circle of the spring cover, the scheme adopted is completely different from the inner diameter surface detection method. Instead, it adopts a displacement sensor detection method. The displacement sensor is fitted with the outer circle of the spring cover to sense the outer circle shape of the spring cover. In this process, the spring cover needs to be in a rotating state at all times, so that the displacement sensor can be conveniently detected. The present invention introduces a power component to provide power through belt transmission. However, in this process, the spring cover needs to be fixed to the driven shaft so that the spring cover can be driven to rotate when the driven shaft rotates. Therefore, the spring cover needs to be fixed to the driven shaft. Specifically, the spring cover is clamped in a number of fan-shaped blocks, and the inner side wall of the spring cover is limited by the fan-shaped blocks to avoid slipping with the spring cover during the rotation of the driven shaft. The fan-shaped blocks can change their limiting area by adjusting the push rod, so that the spring cover can be better limited.

[0034] As a spring cover with rigidity, if it can only form a limited and fixed fit under the clamping action of the adjusting push rod and the rigid fan-shaped clamping block, it is easy to cause irreparable damage to the spring cover. Although the inspection is completed, it cannot be used again. Therefore, the present invention further proposes to provide a rubber outer fitting seat on the fan-shaped clamping block, so that the fan-shaped clamping block can be moved to a position close to the edge of the spring cover in advance by adjusting the push rod, and then the elasticity of the outer fitting seat can be used to compensate for the error.

[0035] The outer mating seat is not just an elastic rubber seat, otherwise even if the spring cover can be mated when it falls, it is not easy for the two to separate when they are separated. Therefore, the present invention divides the outer mating seat into multiple sections. The outermost section uses an outer arc-shaped piece with a rubber pad, which makes it more difficult to fit the spring cover, but relatively simple to separate. In addition, the convex rubber pad is used to allow the outer mating seat to have a certain restraining effect on the inner wall of the spring cover, and the adapter ring with a certain thickness can play a supporting and buffering role to prevent the spring cover from directly contacting the fan-shaped block, and the inner fitting piece arranged on the inside can establish a certain connection with the adjusting push rod to prevent the adjusting push rod from suddenly moving too long and damaging the spring cover.

[0036] As mentioned above, the outer circle of the spring cover is detected by a displacement sensor, but it is obvious that the spring cover has a certain height and level, so the position of the displacement sensor needs to be adjusted during the detection stage so that the displacement sensor can adapt to the level, height and thickness of spring covers of different shapes. In this regard, the present invention further proposes to set a hydraulic push rod and a lifting seat on the displacement sensor, so as to change the height and inclination of the displacement sensor fixed on the guide rod, so that it can monitor spring covers of various shapes, thereby drawing a more detailed trajectory and establishing a more precise model.

[0037] In summary, by using a displacement sensor to detect the outer circle of the spring cover and a pneumatic probe to detect the inner diameter of the spring cover, the thickness, defects, height and other dimensions of the spring cover can be detected more accurately, so as to finely establish a workpiece contour model. The outer diameter size and the form and position tolerances such as the roundness and cylindricity of the workpiece outer circle can be analyzed and calculated through the data model, and the feedback can be given to the system to adjust and set the production equipment in time, thereby improving the product yield.

[0047] All embodiments of the present invention are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0048] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as referring to the purpose, technical solutions and advantages of the methods. To be clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0049] Reference Figures 1 to 8 As shown, a spring cover comprehensive detection device includes: a shell connecting frame 10 arranged on the mounting surface, the shell connecting frame 10 includes a first processing area 11, a second processing area 12, and a third processing area 13; an inner diameter detection structure 20, the inner diameter detection structure 20 includes a first clamp 21 arranged in the first processing area 11, an inner diameter detection member 22 arranged at the rear side of the first clamp 21 and covered on the top of the first clamp 21 after rotation; an outer circle detection structure 30, the outer circle detection structure 30 includes a power assembly 31 arranged in the second processing area 12, and a third inner diameter detection member 22 arranged on the top of the power assembly 31. Two fixtures 32, outer circle detection parts 33 located on both sides of the second fixture 32; a turntable 40, the turntable 40 is located at the end of the outer circle detection structure 30 away from the inner diameter detection structure 20; a plurality of flip structures 50, the flip structures 50 are respectively arranged on the first processing area 11, the second processing area 12, and the third processing area 13, and the spring cover is gradually transferred from the feed end to the turntable 40; a modeling structure, the modeling structure is electrically connected to the inner diameter detection part 22 and the outer circle detection part 33, receives the detection data of the inner diameter detection part 22 and the outer circle detection part 33 and accurately establishes the workpiece shape contour model.

[0050] Reference Figures 1 and 2 It can be seen that the spring cover detected in this embodiment is not a regular shape, and has at least two layers on its outer side, while at least five surfaces need to be detected on the inner side to truly feedback the true structure of the spring cover.

[0051] During the overall inspection process, since pneumatic probe inspection and displacement sensor inspection are used, there are no excessive environmental requirements during inspection. It only needs to be in a windless and relatively dust-free environment and can be set in a relatively sealed shell connecting frame 10. In order to distinguish the processing areas, the shell connecting frame 10 is further divided into a first processing area 11, a second processing area 12, and a third processing area 13. The various areas are separated by partitions to avoid mutual influence between the partitions.

[0052] During the detection process, it is not like the existing technology that only detects the inner diameter or outer circle part of the cover structure, but adopts a method of simultaneous detection of the inner diameter and outer circle. Specifically, in this embodiment, by establishing a complete set of comprehensive detection structures for spring covers, the inner diameter detection structure 20 is first used to detect the inner side of the spring cover, and the modeling structure establishes a model of the inner side of the spring. Then, the outer side of the spring cover is monitored through the outer circle detection structure 30, and the modeling structure establishes a model of the outer side of the spring cover, so that a complete three-dimensional model of the spring cover can be established. In the event that the spring cover has depressions, protrusions, horizontal lines, or inaccurate dimensions, it can be fully reflected and the difference between the actual size and the processed size can be displayed, so that the user can accurately correct the production structure, improve the product yield, and quickly modify the equipment parameters.

[0053] In fact, after drawing the model, it is necessary to compare the models. During the comparison process, the spring cover is located on the transfer table 40. The transmission direction is determined by comparing the content, which eliminates the need for manual classification at a later stage and is more efficient.

[0054] In this embodiment, the flipping structure 50 is a robot arm, and can also be set to a more complex flipping structure, as long as it can achieve the effects of rotation and position change.

[0055] In the process of detecting the inner diameter of the spring cover, it needs to be in a fixed state, so the present invention utilizes a first fixture 21 for clamping, and the first fixture 21 includes a clamping member 211 locked on the first processing area 11, and a clamping claw 212 connected to the clamping member 211, and an inner groove 2121 adapted to the curvature of the spring cover is provided on the inner side of the clamping claw 212, and the spring cover is directly supported by the inner groove 2121. Since it needs to be loaded upside down, the inner diameter detection member 22 is not initially arranged above the first fixture 21, but is arranged in an eccentric manner. The inner diameter detection member 22 includes a mounting seat 221 vertically fixed on the first processing area 11, and a rotating table locked on the top of the mounting seat 221. 222, a push rod motor 223 welded on the rotating table 222, a straight arm 224 locked above the push rod motor 223, and an inner section detection structure 225 located at the bottom of the straight arm 224. The inner section detection structure 225 corresponds to the inner section of the spring cover. The rotating table 222 is used to rotate the inner section detection structure 225 to the position of the spring cover corresponding to the first clamp 21, and then it is lowered to the corresponding position by the push rod motor 223, so that the inner section detection structure 225 is in a suspended state and does not directly contact the spring cover, thereby not causing the spring cover to shift during the detection process. Each area of ​​the inner side of the spring cover can be accurately detected one by one to avoid repeated detection and missed detection.

[0056] As mentioned above, since the spring cover is not simply an open cylindrical structure, it has multiple layers and there are other inner rings inside, so it is more difficult to detect the inner side of the spring cover. In this regard, the inner surface detection structure 225 of the present invention includes an output motor 2251 welded below the end of the straight arm 224, a lower loading plate 2252 locked at the bottom of the output motor 2251, an outer ring detection plate 2253 arranged below the lower loading plate 2252, an outer ring detection structure 2254 arranged inside the outer ring detection plate 2253, an inner ring detection plate 2255 located on the inner side of the outer ring detection plate 2253, and an inner ring detection structure 2256 arranged inside the inner ring detection plate 2255. The outer ring detection structure 2254 and the inner ring detection disk 2255 are connected and fixed by a connecting ring 2257, and the inner surface detection structure 225 is specifically divided into the outer ring detection structure 2254 and the inner ring detection structure 2256, so that the detection can be carried out in different areas. When forming the model, the hierarchy between the various areas can be more obvious, and the generated model is closer to the physical model. Both the outer ring detection structure 2254 and the inner ring detection structure 2256 use the same output motor 2251 as the power part, and its rotation drives the outer ring detection structure 2254 and the inner ring detection structure 2256 to rotate, so that the spring cover does not move, and the outer ring detection structure 2254 and the inner ring detection structure 2256 rotate around the inner diameter surface of the spring cover.

[0057] However, due to the problem of different detection surfaces caused by the partitioned detection, there is a certain difference in the detection of the outer ring area and the inner ring area, that is, the detected wall surfaces are different. In this regard, the present invention first proposes an outer ring detection structure 2254, wherein the outer ring detection structure 2254 includes a first quick connector 22541 clamped in the outer ring detection disk 2253, a first bottom pneumatic probe 22542 vertically fixed below the first quick connector 22541, and a first transverse pneumatic probe 22543 perpendicular to the first bottom pneumatic probe 22542 and parallel to the outer ring detection disk 2253. The first bottom pneumatic probe 22542 and the first transverse pneumatic probe 22543 are both connected to an external air source. The outer ring of the inner side surface of the spring cover is detected in detail by the first bottom pneumatic probe 22542 and the first transverse pneumatic probe 22543 on the outer ring detection structure 2254, thereby forming two relatively complete model surfaces. Subsequently, the present invention further proposes an inner ring detection structure 225 6. The inner ring detection structure 2256 includes a second quick connector 22561 clamped in the inner ring detection plate 2255, a second bottom pneumatic probe 22562 fixed vertically below the second quick connector 22561, a second transverse pneumatic probe 22563 perpendicular to the second bottom pneumatic probe 22562 and parallel to the inner ring detection plate 2255, and a third transverse pneumatic probe 22564 in the same line as the second transverse pneumatic probe 22563. The second bottom pneumatic probe 22562, the second lateral pneumatic probe 22563, and the third lateral pneumatic probe 22564 are all connected to an external air source to perform special inspection on the inner ring of the three-sided structure. The second bottom pneumatic probe 22562, the second lateral pneumatic probe 22563, and the third lateral pneumatic probe 22564 are used to form three relatively complete model surfaces. In the process of combining the inner ring detection structure 2256 with the outer ring detection structure 2254, a complete inner model surface is formed.

[0058] However, if the detection is only performed through an inner section detection structure 225, the detected structure is only a flat surface structure, not a three-dimensional solid structure, and it is completely unable to fit the physical model. Therefore, the present invention introduces an outer circle detection part 33 in the second processing area 12. In the process of detecting the outer circle of the spring cover, the scheme adopted is completely different from the inner diameter surface detection method. Instead, a displacement sensor 337 is used for detection. The displacement sensor 337 fits with the outer circle of the spring cover to sense the outer circle shape of the spring cover. In this process, the spring cover needs to be in a rotating state at all times to facilitate the detection of the displacement sensor 337. Therefore, the present invention introduces a power component 31, which includes an active motor 311 and a fixed pile 312 vertically fixed on the second processing area 12, a driven shaft 313 movably inserted in the fixed pile 312, a belt 314 connected between the output shaft of the active motor 311 and the driven shaft 313, and a second clamp 32 including a locking The plurality of adjusting push rods 321 at the top of the driven shaft 313, the sector-shaped clamping block 322 fixed on the adjusting push rod 321, the outer matching seat 323 of the clamp on all the sector-shaped clamping blocks 322, the outer matching seat 323 is movably connected with the descending spring cover, and during the detection process, the active motor 311 drives the driven shaft 313 on the fixed pile 312 to rotate through the belt 314, and the power is provided by the transmission of the belt 314. However, in this process, the spring cover needs to be fixed to The spring cover is on the driven shaft 313, so that the spring cover can be driven to rotate when the driven shaft 313 rotates. Therefore, the spring cover needs to be fixed to the driven shaft 313. Specifically, the spring cover is clamped in a plurality of fan-shaped blocks 322, and the inner side wall of the spring cover is limited by the fan-shaped blocks 322 to avoid slipping with the spring cover during the rotation of the driven shaft 313. The fan-shaped blocks 322 can change their limiting area by adjusting the push rod 321, so that the spring cover can be better limited.

[0059] The spring cover in this embodiment has not only a certain rigidity but also a certain elasticity. As a spring cover with rigidity, if it can only form a limited and fixed fit under the clamping action of the adjusting push rod 321 and the rigid fan-shaped clamping block 322, it is easy to cause the spring cover to be irreparably damaged. Although the inspection is completed, it cannot be used again. Therefore, the present invention further proposes to provide a rubber outer fitting seat 323 on the fan-shaped clamping block 322, so that the fan-shaped clamping block 322 can be moved to a position close to the edge of the spring cover in advance by adjusting the push rod 321, and then the elasticity of the outer fitting seat 323 can be used to compensate for the error. However, the outer fitting seat 323 is not just an elastic rubber seat. Otherwise, even if the spring cover can form a fit when it falls, it is not easy for the two to separate when they are separated. Therefore, the outer fitting seat 323 of the present invention includes an adapter ring 3231 tightened on the outside of all the fan-shaped clamping blocks 322, an outer arc piece 32 glued to the outside of the adapter ring 3231 32, the outer arc-shaped piece 3232 is integrally formed with the adhesive pad 3233 on the inner wall of the spring cover, and the inner fitting piece 3234 is glued to the adapter ring 3231. The inner fitting piece 3234 is a folded piece set at an obtuse angle. The end of the inner fitting piece 3234 is nailed to the adjustment rod of the adjustment push rod 321. The outer matching seat 323 is divided into multiple sections. The outermost section uses the outer arc-shaped piece 3232 with the adhesive pad 3233 to make the spring cover more stable when fitting. The outer fitting seat 323 has a certain restraining effect on the inner wall of the spring cover, and the adapter ring 3231 with a certain thickness can play a supporting and buffering role, preventing the spring cover from directly contacting the fan-shaped block 322, and the inner fitting piece 3234 arranged on the inside can establish a certain connection with the adjusting push rod 321, preventing the adjusting push rod 321 from suddenly moving too long and damaging the spring cover.

[0060] As mentioned above, the outer circle of the spring cover is detected by the displacement sensor 337, but it is obvious that the spring cover has a certain height and level, so the position of the displacement sensor 337 needs to be adjusted during the detection stage, so that the displacement sensor 337 can adapt to the level, height and thickness of spring covers of different shapes. In this regard, the outer circle detection member 33 of the present invention includes a clamping seat 331 locked on the second processing area 12, a hydraulic push rod 332 provided on the clamping seat 331, a hinge seat 333 fixed to the top of the hydraulic push rod 332, and a welding A clamping sleeve 334 is provided at the bottom of the rotating shaft of the articulated seat 333, a guide rod 335 is provided in the clamping sleeve 334, a lifting seat 336 is provided below the middle position of the guide rod 335, and a displacement sensor 337 is provided at one end of the inner side of the guide rod 335. By further proposing to provide a hydraulic push rod 332 and a lifting seat 336 on the displacement sensor 337, the height and inclination of the displacement sensor 337 fixed on the guide rod 335 can be changed, so that it can monitor spring covers of various shapes, thereby drawing a more detailed trajectory and establishing a more precise model.

[0061] In summary, by using the displacement sensor 337 to detect the outer circle of the spring cover and the pneumatic probe to detect the inner diameter of the spring cover, the thickness, defects, height and other dimensions of the spring cover can be detected more accurately, so as to finely establish the workpiece contour model. The outer diameter size and the form and position tolerances such as the roundness and cylindricity of the outer circle of the workpiece are analyzed and calculated through the data model, and the feedback can be given to the system to adjust and set the production equipment in time, thereby improving the product yield.

[0062] In another embodiment of the present invention, a spring cover comprehensive detection method is provided, which uses the above-mentioned spring cover comprehensive detection device, and the specific steps include:

[0063] S1: Use the flipping structure 50 to flip the bottom surface of the spring cover upward and fix it in the first fixture 21. After the spring cover is in place, rotate the inner diameter detection member 22 to the top of the spring cover. The outer ring detection structure 2254 and the inner ring detection structure 2256 in the inner diameter detection member 22 respectively perform pneumatic detection on both sides of the inner side of the spring cover. The pneumatic detection data is transmitted back to the modeling structure;

[0064] S2: Use the flip structure 50 to flip the top surface of the spring cover upward and fix it in the second clamp 32. Adjust the second clamp 32 so that it can flexibly fix the spring cover. Rotate the entire second clamp 32 to rotate the spring cover accordingly. Move the outer circle detection member 33 to detect the outer side of the spring cover. The displacement trajectory data is transmitted back to the modeling structure.

[0065] S3: The modeling structure gathers the data obtained from the inner diameter detection part 22 and the outer circle detection part 33 to build a model, and finely establishes the workpiece contour model, and compares and screens it with the pre-drawn three-dimensional model of the spring cover;

[0066] S4; The spring cover with the inner diameter and outer circle inspected is flipped onto the transfer table 40 by the flipping structure 50. The model after modeling that is consistent with the pre-drawn model is transferred to the qualified end by the flipping structure 50. The model after modeling that is consistent with the pre-drawn model is transferred to the unqualified end by the flipping structure 50.

[0067] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
