Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of white body detection, and particularly relates to an automobile white body detection table convenient to adjust. BACKGROUND

[0002] The automobile white body refers to the body structure after the welding process is completed and before the coating process, which is mainly assembled by stamping parts through welding, and usually does not include movable parts such as doors, engine covers and trunk lids. In order to ensure the assembly accuracy and matching quality of the subsequent interior and exterior parts, the geometric size of the white body must strictly meet the ideal state of the design requirements.

[0003] In order to realize accurate evaluation and effective control of the manufacturing precision of the white body, the three-coordinate measurement technology (CMM) becomes a key means. The three-coordinate detection of the white body is a technical process of systematically measuring the three-dimensional space size, geometric tolerance and assembly precision of the white body by using a high-precision three-coordinate measuring machine, which is widely used in the key link of verifying the geometric consistency of the body and controlling the production quality in the automobile manufacturing process. The measurement precision of the technology can reach 0.01 mm level, can comprehensively cover the key functional areas of the body (such as chassis mounting points and suspension hole positions) and appearance matching areas (such as door holes and wing panel gap surfaces), involves hundreds of key measuring points, and has high quantification and traceability.

[0004] The typical three-coordinate detection system configuration includes cantilever measuring machines located on both sides of the detection workbench, and a special detection workbench is arranged in the middle. The workbench is provided with corresponding support positioning devices according to the specific vehicle model, mainly including a plurality of customized support frames. Each support frame is provided with a positioning pin for precise cooperation with the reference hole on the body bottom longitudinal beam, and a plurality of support blocks are arranged to contact and support the key surface, so that the white body is rigidly fixed during the detection process, any slight displacement is prevented, and the stability and repeatability of the measurement result are ensured.

[0005] During detection, the white body is placed on the detection tooling by hoisting equipment, and the positioning pin is matched with the reference hole and the support block is contacted with the key surface, so that the rapid positioning and reliable clamping are completed. Subsequently, based on the body tooling main reference system (such as the positioning hole and support point on the longitudinal beam), the three-coordinate measuring head automatically collects the spatial coordinate data of 3 to 6 reference balls or reference holes, establishes an accurate space rectangular coordinate system (X / Y / Z axis) by means of a professional measurement software (such as PC-DMIS), and automatically calculates the coordinate origin, which significantly reduces the human operation error and improves the consistency and efficiency of the measurement.

[0006] However, when faced with the practical needs of mixed production lines for multiple vehicle models or frequent model changeover testing, each time the testing model is changed, multiple support frames on the testing bench must be replaced entirely. The current method relies on disassembling and retightening the fixing bolts between the support frames and the testing bench one by one. This process is cumbersome and time-consuming, increasing the preparation time for model changeovers and seriously affecting the testing cycle time and overall efficiency. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the present invention provides an easily adjustable automotive body-in-white inspection platform, the specific technical solution of which is as follows:

[0008] An easily adjustable automotive body-in-white inspection platform includes an inspection platform body located between two cantilever inspection machines and multiple support frames located above the inspection platform body. A first movable plate and a second movable plate are slidably connected to the inspection platform body. The multiple support frames for supporting the body-in-white are divided into two groups and fixedly installed on the top surfaces of the first movable plate and the second movable plate. The bottom surfaces of the first movable plate and the second movable plate are each provided with multiple sets of first sliding grooves and second sliding grooves. Each set of first sliding grooves and second sliding grooves is connected. Sliding components are connected within the second sliding grooves and the first sliding grooves. Two sets of limiting structures are connected to both ends of the inspection platform body. Guide structures are connected to both ends of the inspection platform body. A snap-fit ​​structure is connected between the first movable plate and the second movable plate.

[0009] In some embodiments, the sliding assembly includes a plurality of T-shaped plates, each of which is fixedly connected to the bottom surface of the first movable plate and the second movable plate, each of which is slidably connected to a corresponding second sliding groove, and each of which has a long groove on its bottom surface, wherein a plurality of pulleys are fixedly installed in the long groove, and the pulleys are slidably connected to the first sliding groove.

[0010] In some embodiments, the two sets of limiting structures include a movable block located at the outer end of the detection platform body, the first movable plate, and the second movable plate. The inner wall of the movable block is provided with a U-shaped groove, and a U-shaped insert is slidably connected in the U-shaped groove. The U-shaped insert passes through the U-shaped groove and is inserted into the outer wall of the detection platform body, the first movable plate, and the second movable plate. The bottom of the movable block is connected to a telescopic member connected to the detection platform body.

[0011] In some embodiments, the telescopic component includes a sliding sleeve, a sliding column slidably connected inside the sliding sleeve, a second spring fixedly connected to one end of the sliding column inside the sliding sleeve, the other end of the second spring fixedly connected to the bottom surface of the inner wall of the sliding sleeve, the end of the sliding column away from the second spring fixedly connected to the bottom surface of the moving block, two symmetrically arranged limiting plates fixedly connected to the bottom surface of the moving block, extension plates fixedly connected to both sides of the outer wall of the sliding sleeve, the extension plates having limiting grooves for sliding of the limiting plates, a base plate fixedly connected to the bottom surface of the sliding sleeve, a side plate fixedly connected to one side of the base plate, a second bolt threadedly connected to the side plate for connection to the detection platform body, two symmetrically arranged third springs fixedly connected to one side of the U-shaped insert block inside the U-shaped groove, the other ends of the two third springs fixedly connected to the inner wall of the U-shaped groove, a moving column fixedly connected to one side of the U-shaped insert block inside the U-shaped groove, the moving column being located between the two third springs, the end of the moving column away from the U-shaped insert block passing through the moving block and slidably connected to the moving block.

[0012] In some embodiments, the end of the movable column away from the U-shaped insert passes through the movable block and is fixedly connected to a pull plate. A horizontal groove is provided on the outer wall of the movable block, and a horizontal block is slidably connected in the horizontal groove. An inclined block is fixedly connected to the outer end of the horizontal block. The inclined surface of the inclined block is slidably connected to the inner wall of the pull plate, and a push plate for pushing the inclined block is fixedly connected to the bottom surface of the inclined block.

[0013] In some embodiments, the guide structure includes two sets of symmetrically arranged guide plates, which are located at both ends of the detection table body. An extension plate is fixedly connected to the end of the guide plate near the detection table body. A first bolt is threaded onto the top surface of the extension plate. The first bolt passes through the extension plate and is threaded into the detection table body. An inclined edge is formed on the inner wall of the end of the guide plate away from the first bolt.

[0014] In some embodiments, the snap-fit ​​structure includes a first end plate and a second end plate, which are staggered vertically. Each end plate has a vertical groove. The first end plate is fixedly connected to the end of a second movable plate near the first movable plate, and the second end plate is fixedly connected to the end of the first movable plate near the second movable plate. An insert plate is slidably connected within the vertical groove on the first end plate. The insert plate is inserted into the vertical groove on the second end plate. Enlarged plates are fixedly connected to both sides of the top of the insert plate. A first spring is fixedly connected to the bottom surface of the enlarged plate, and the other end of the first spring is fixedly connected to the top surface of the first end plate. A chamfer is formed on the side of the insert plate near the second end plate.

[0015] In some embodiments, a rotating plate is rotatably connected to the top surface of the insert plate, a convex plate for rotation is fixedly connected to the outer wall of the rotating plate, and the bottom surface of the rotating plate is in contact with the top surface of the second movable plate.

[0016] In some embodiments, the top surfaces of the first movable plate and the second movable plate are provided with grooves, and a U-shaped handle is rotatably connected in the grooves. The two longitudinal rods of the U-shaped handle are rotatably connected to a rotating shaft, and the rotating shaft is fixedly installed with the first movable plate and the second movable plate.

[0017] In some embodiments, the outer wall of the U-shaped handle crossbar is provided with a clearance groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Firstly, this solution utilizes the coordinated design of the first and second moving plates. When inspecting different vehicle models or requiring the replacement or adjustment of support frames, the replacement and adjustment of the support frames can be pre-completed on the idle moving plates. Simply remove the currently used moving plate from the inspection area, and simultaneously move the other ready moving plate from the standby area to the inspection area, achieving precise positioning with the inspection platform. This switching process is fast and stable, completely eliminating support frame replacement and adjustment from inspection time, avoiding the prolonged downtime caused by on-site bolt removal and installation in traditional methods. Therefore, the replacement of multiple support frames no longer occupies actual inspection time, significantly improving the overall efficiency and production flexibility of the coordinate measuring machine (CMM).

[0020] Secondly, this design, through the cooperative design of the pulley and the first sliding groove, achieves smooth guidance of the first and second moving plates during movement, significantly reducing frictional resistance and facilitating smooth push-pull operations when replacing the support frame. Simultaneously, the cooperative structure of the T-shaped plate and the second sliding groove effectively constrains the movement trajectory of the moving plate, ensuring precise lateral sliding when the moving plate overlaps with the testing platform body, preventing offset or misalignment, thereby guaranteeing that the moving plate can be smoothly and accurately aligned and reliably positioned with the top surface of the testing platform body.

[0039] like Figures 1 to 10As shown, an easily adjustable automotive body-in-white inspection platform includes an inspection platform body 4 located between two cantilever inspection machines 3 and multiple support frames 45 located above the inspection platform body 4. A first movable plate 1 and a second movable plate 2 are slidably connected to the inspection platform body 4. The multiple support frames 45 for supporting the body-in-white are divided into two groups and fixedly installed on the top surfaces of the first movable plate 1 and the second movable plate 2. Multiple sets of first sliding grooves 7 and second sliding grooves 20 are formed on the bottom surfaces of the first movable plate 1 and the second movable plate 2. Each set of first sliding grooves 7 and second sliding grooves 20 is connected. Sliding components are connected in the second sliding groove 20 and the first sliding groove 7. Two sets of limiting structures are connected to both ends of the inspection platform body 4. Guide structures are connected to both ends of the inspection platform body 4. A snap-fit ​​structure is connected between the first movable plate 1 and the second movable plate 2.

[0040] like Figure 1 and Figure 10 As shown, the easily adjustable car body-in-white inspection platform of the present invention requires the replacement of the first moving plate 1 located on the inspection platform body 4 when inspecting different car models. During the inspection of the previous car body-in-white by the first moving plate 1, the support frame 45 on the second moving plate 2 can be pre-replaced and adjusted to ensure that the support frame 45 on the second moving plate 2 is adapted to the next car body-in-white to be inspected. After the previous car body-in-white is inspected, the car body-in-white is dropped out using a lifting device. Then, the limiting structures at both ends of the inspection platform body 4 are removed, so that the two ends of the first moving plate 1 on the inspection platform body 4 are no longer restricted. Then, the snap-fit ​​structure is operated to connect the first moving plate 1 and the second moving plate 2. Then, the first moving plate 1 can be pulled out of the inspection platform body 4, and the adjusted second moving plate 2 slides into the inspection area from the placement side, that is, it slides into the first sliding groove 7 and the second sliding groove 20 on the inspection platform body 4 through the sliding component, so that the second moving plate 2 is limited in lateral position on the inspection platform body 4.

[0041] Then, the snap-fit ​​assembly is released, separating the first moving plate 1 and the second moving plate 2. After that, the limiting structure is used to restrict the second moving plate 2 and the two ends of the inspection table body 4, so that the second moving plate 2 is restricted in both the horizontal and vertical directions on the inspection table body 4 and cannot move. At this time, the first moving plate 1 has moved from the inspection area to the waiting area. The worker lifts the body-in-white onto the second moving plate 2 and uses the support frame 45 for positioning and support, and then the three-coordinate inspection of the body-in-white of different models can be performed.

[0042] Subsequently, the first movable plate 1 that has been replaced is already in the standby area. At this time, the worker disassembles, replaces and adjusts the support frame 45 on the first movable plate 1. This allows the support frame 45 for the next different vehicle model to be inspected to be adjusted in advance without taking up inspection time. Each body-in-white inspection takes a certain amount of time, so there is no need to rush the replacement process of the support frame 45.

[0043] By cooperating with the first moving plate 1 and the second moving plate 2, when different vehicle models require adjustment of the support frame 45, it is only necessary to replace and adjust the support frame 45 on the idle moving plate in advance, move the moving plate to be used out of the inspection area, and at the same time, the idle moving plate enters the inspection area from the standby area and is limited to the inspection table body 4, so as to achieve precise positioning of the moving plate for inspection. In this way, the replacement of multiple support frames 45 no longer takes up inspection time, greatly improving inspection efficiency.

[0044] It should be noted that the first moving plate 1 and the second moving plate 2 are used interchangeably. If the second moving plate 2 is used normally, then the first moving plate 1 is idle. Conversely, the second moving plate 2 is idle. The first moving plate 1 and the second moving plate 2 move left and right on the detection table body 4. That is, when the first moving plate 1 moves from the left standby area to the detection area, the second moving plate 2 moves from the detection area to the right standby area. The next time, the second moving plate 2 moves from the right standby area to the detection area, and the first moving plate 1 moves from the detection area to the left standby area. This process is repeated.

[0045] As a preferred embodiment of the present invention, the sliding assembly includes a plurality of T-shaped plates 8, each of the T-shaped plates 8 being fixedly connected to the bottom surface of the first moving plate 1 and the second moving plate 2, each of the T-shaped plates 8 being slidably connected to the corresponding second sliding groove 20, and each of the bottom surfaces of the T-shaped plates 8 having an elongated groove 9, wherein a plurality of pulleys 10 are fixedly installed in the elongated groove 9, and the pulleys 10 are slidably connected to the first sliding groove 7.

[0046] Specifically, when the first moving plate 1 and the second moving plate 2 move left and right, the pulleys 10 in the long grooves 9 on the bottom surface of the T-shaped plate 8 at their bottom are used for movement. The T-shaped plate 8 will be inserted into the second sliding groove 20 on the detection table body 4 during movement, and the pulleys 10 will move in the first sliding groove 7.

[0047] It should be noted that the pulley 10 can be a combination of omnidirectional and linear wheels, which facilitates the multi-directional movement of the moving plate in the waiting area. The T-shaped plate 8 and the second slide groove 20 ensure that the moving plate can smoothly slide laterally with the detection table body 4 and overlap and align.

[0048] The cooperation between the pulley 10 and the first slide groove 7 makes the first moving plate 1 and the second moving plate 2 move smoothly, which is convenient for replacement. The cooperation between the T-shaped plate 8 and the second slide groove 20 allows the moving plate to maintain lateral movement when it overlaps with the inspection table body 4, ensuring that the moving plate overlaps with the top surface of the inspection table body 4.

[0049] As a preferred embodiment of the present invention, the two sets of limiting structures include a movable block 22, which is located at the outer end of the detection platform body 4, the first movable plate 1, and the second movable plate 2. A U-shaped groove 35 is provided on the inner wall of the movable block 22, and a U-shaped insert 26 is slidably connected in the U-shaped groove 35. The U-shaped insert 26 passes through the U-shaped groove 35 and is inserted into the outer wall of the detection platform body 4, the first movable plate 1, and the second movable plate 2. A telescopic member connected to the detection platform body 4 is connected to the bottom of the movable block 22.

[0050] Specifically, after the moving plate enters the detection area, the moving block 22 can be moved upward, so that the moving block 22 drives the U-shaped plug 26 inside it to move upward at the same time. Then, the U-shaped plug 26 is inserted into the moving plate and the detection table body 4 to ensure that the two ends of the moving plate are locked and connected to the two ends of the detection table body 4, so as to ensure that the position of the moving plate on the detection table body 4 is stable during the detection process.

[0051] When the movable plate needs to be removed, first move the U-shaped insert 26 backward so that it enters the U-shaped groove 35, thus separating the U-shaped insert 26 from the detection table body 4 and the movable plate. Then press the movable block 22, and under the action of the telescopic component, the movable block 22 descends and separates from the movable plate. At this time, it can be ensured that the movable plate in the detection area is no longer restricted from the detection table body 4, thus ensuring that the movable plate can be removed smoothly.

[0052] In a preferred embodiment of the present invention, the telescopic component includes a sliding sleeve 28, within which a sliding column 27 is slidably connected. One end of the sliding column 27 within the sliding sleeve 28 is fixedly connected to a second spring 34. The other end of the second spring 34 is fixedly connected to the bottom surface of the inner wall of the sliding sleeve 28. The end of the sliding column 27 away from the second spring 34 is fixedly connected to the bottom surface of a moving block 22. Two symmetrically arranged limiting plates 37 are fixedly connected to the bottom surface of the moving block 22. Extension plates 32 are fixedly connected to both sides of the outer wall of the sliding sleeve 28. Each extension plate 32 has a limiting groove 33 for sliding of the limiting plates 37. A base plate 29 is fixedly connected to the bottom surface of the 8. A side plate 30 is fixedly connected to one side of the base plate 29. A second bolt 31 connected to the detection table body 4 is threaded onto the side plate 30. Two symmetrically arranged third springs 40 are fixedly connected to one side of the U-shaped insert 26 located in the U-shaped groove 35. The other ends of the two third springs 40 are fixedly connected to the inner wall of the U-shaped groove 35. A movable column 41 is fixedly connected to one side of the U-shaped insert 26 located in the U-shaped groove 35. The movable column 41 is located between the two third springs 40. The end of the movable column 41 away from the U-shaped insert 26 passes through the movable block 22 and is slidably connected to the movable block 22.

[0053] As a preferred embodiment of the present invention, the end of the movable column 41 away from the U-shaped insert 26 passes through the movable block 22 and is fixedly connected to a pull plate 25. A horizontal groove 38 is provided on the outer wall of the movable block 22. A horizontal block 42 is slidably connected in the horizontal groove 38. An inclined block 24 is fixedly connected to the outer end of the horizontal block 42. The inclined surface of the inclined block 24 is slidably connected to the inner wall of the pull plate 25. A push plate 39 for pushing the inclined block 24 is fixedly connected to the bottom surface of the inclined block 24.

[0054] As a preferred embodiment of the present invention, the guide structure includes two sets of symmetrically arranged guide plates 5, which are located at both ends of the detection table body 4. An extension plate 44 is fixedly connected to the end of the guide plate 5 near the detection table body 4. A first bolt 6 is threadedly connected to the top surface of the extension plate 44. The first bolt 6 passes through the extension plate 44 and is threadedly connected to the detection table body 4. An inclined edge 43 is provided on the inner wall of the end of the guide plate 5 away from the first bolt 6.

[0055] Specifically, when the moving block 22 needs to be moved down and separated from both ends of the moving plate, the push plate 39 can be pushed. The push plate 39 drives the inclined block 24, and the inclined block 24 drives the horizontal block 42 to slide in the horizontal groove 38. When the inclined block 24 moves laterally, its inclined surface will squeeze the pull plate 25 to move backward, driving the moving column 41 to move backward on the outer wall of the moving block 22. The moving column 41 drives the U-shaped insert 26 to move backward in the U-shaped groove 35. The U-shaped insert 26 squeezes the third spring 40 to compress. At this time, the U-shaped insert 26 has separated from the moving plate and the detection table body 4.

[0056] At this time, after the U-shaped insert 26 is located in the U-shaped groove 35 of the moving block 22, the moving block 22 is no longer restricted, the second spring 34 will contract, and drive the sliding column 27 to slide down in the sliding sleeve 28, thereby driving the moving block 22 to descend. In this way, the moving block 22 is no longer restricted by the outer end of the moving plate. By performing the above operation on all four moving blocks 22, both ends of the moving plate will be unrestricted, and the moving plate can be moved out.

[0057] When the movable plate is pushed onto the testing platform body 4, it pulls the movable block 22 upward, causing the sliding column 27 to move within the sliding sleeve 28. At the same time, the second spring 34 is stretched. Simultaneously, the limiting plates 37 on both sides of the bottom surface of the movable block 22 slide upward within the limiting grooves 33 in the extension plate 32. During the upward movement of the movable block 22, the inclined block 24 is reset, causing the horizontal block 42 to move and reset within the horizontal groove 38. At this time, the elastic potential energy of the third spring 40 is reset, pulling the pull plate 25 and the movable column 41 back. When the movable block 22 slides to a certain position, the U-shaped insert 26 will be inserted into the movable plate and the testing platform body 4 under the action of the third spring 40, completing the positioning. The other three movable blocks 22 are operated in the same way to complete the four-corner positioning of the movable plate.

[0058] As a preferred embodiment of the present invention, the snap-fit ​​structure includes a first end plate 12 and a second end plate 18, which are staggered vertically. Both the first end plate 12 and the second end plate 18 have vertical grooves 19. The first end plate 12 is fixedly connected to the end of the second movable plate 2 near the first movable plate 1, and the second end plate 18 is fixedly connected to the end of the first movable plate 1 near the second movable plate 2. An insert plate 13 is slidably connected within the vertical groove 19 on the first end plate 12. The insert plate 13 is inserted into the vertical groove 19 on the second end plate 18. Enlarging plates 14 are fixedly connected to both sides of the top of the insert plate 13. A first spring 15 is fixedly connected to the bottom surface of the enlarging plate 14. The other end of the first spring 15 is fixedly connected to the top surface of the first end plate 12. A chamfer is formed on the side of the insert plate 13 near the second end plate 18.

[0059] Specifically, when it is necessary to replace the movable plate, the first end plate 12 and the second end plate 18 can be brought close to each other, with the outer end of the second end plate 18 abutting against the chamfer at the lower end of the insert plate 13. As the first end plate 12 and the second end plate 18 continue to move closer, the chamfer of the insert plate 13 is squeezed and rises in the vertical groove 19. When it rises, it will cause the first spring 15 on the bottom surface of the enlarged plate 14 to stretch. After the insert plate 13 rises, the first end plate 12 and the second end plate 18 can continue to move. Because the first end plate 12 and the second end plate 18 are staggered vertically, when the insert plate 13 encounters the vertical groove 19 on the second end plate 18, under the elastic potential energy of the first spring 15, the insert plate 13 automatically inserts into the vertical groove 19, so that the first movable plate 1 and the second movable plate 2 form a whole. No matter which movable plate is moved, it can drive the other movable plate to move.

[0060] As a preferred embodiment of the present invention, the top surface of the insert plate 13 is rotatably connected to a rotating plate 16, the outer wall of the rotating plate 16 is fixedly connected to a convex plate 17 for rotation, and the bottom surface of the rotating plate 16 is in contact with the top surface of the second moving plate 2.

[0061] Specifically, when it is necessary for the insert plate 13 to disengage from the vertical groove 19, the insert plate 13 can be pulled up to disengage from the vertical groove 19 in the second end plate 18 and rise within the sliding vertical groove 19. Then, the rotating plate 16 at the top of the insert plate 13 is rotated until it abuts against the top surface of the second moving plate 2. Under the tension of the first spring 15, the rotating plate 16 will always exert downward force and abut against the top surface of the second moving plate 2 to limit its movement. This ensures that the insert plate 13 no longer moves and is limited. The protrusion plate 17 facilitates the rotation of the rotating plate 16.

[0062] As a preferred embodiment of the present invention, the top surfaces of the first movable plate 1 and the second movable plate 2 are both provided with grooves 21, and a U-shaped handle 11 is rotatably connected in the grooves 21. The two longitudinal rods of the U-shaped handle 11 are rotatably connected to a rotating shaft 23, and the rotating shaft 23 is fixedly installed with the first movable plate 1 and the second movable plate 2.

[0063] As a preferred technical solution of the present invention, the outer wall of the crossbar of the U-shaped handle 11 is provided with a clearance groove 36.

[0064] Specifically, when the movable plate needs to be moved, the U-shaped handle 11 is rotated out of the groove 21 by rotating the relief groove 36, and then the movable plate is moved by using the U-shaped handle 11. Since the two movable plates have been connected by the insert plate 13 and the vertical groove 19 to form a whole, the movable plate can be moved easily.

[0065] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the claims of the present invention.
