Description

Technical Field

[0001] This invention relates to the field of body-in-white support technology, and in particular to a body-in-white support platform. Background Technology

[0002] The body-in-white support platform is a key process equipment in automobile manufacturing and testing. It is mainly used to support, position, and fix the unpainted body shell (i.e., body-in-white) to meet the needs of assembly, testing, or transportation.

[0003] A support platform for body-in-white inspection is disclosed in patent announcement number CN207280407U. The support platform includes a base plate, a measuring support, and a body positioning device. The base plate is covered with evenly distributed circular holes arranged in a rectangular pattern. The measuring support is fixed to the base plate by a support positioning pin and fasteners passing through a rectangular plate at its bottom and the circular holes. Because the base plate is covered with circular holes, the measuring support can be fixed at almost any position on the base plate. A single base plate can be used for inspecting body-in-white of various vehicle models, and switching between measuring supports is convenient and quick. Since the position of the body positioning device is adjustable, the accuracy of subsequent support development can be guaranteed, achieving precise positioning of the body-in-white and solving the problems of low positioning accuracy, high cost, and large space occupation caused by inconsistent body-in-white positioning in existing technologies. In addition, the support platform can also be used for measuring other components besides the body-in-white.

[0004] When the aforementioned support platform is in use, it is fixed by a series of evenly distributed rectangular circular holes on the base plate. Different circular holes can be used to fix the measuring support structure in different positions on the base plate. However, the positions of the circular holes are fixed. Therefore, there are still certain limitations when adjusting the measuring support structure. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a body-in-white support platform, the specific technical solution of which is as follows:

[0006] A body-in-white support platform includes a platform frame. A support frame is fixedly connected to the lower surface of the platform frame. Two slide rods are slidably connected to the upper surface of the platform frame, and each slide rod has a groove at both ends. A connecting rod is slidably connected to the inner wall of the groove, and a support structure is fixedly connected to one end of the connecting rod. A first bolt is threadedly connected to the outer wall of the slide rod, and one end of the first bolt passes through the slide rod and abuts against the connecting rod. A sliding sleeve is fixedly connected to the lower surface of the slide rod and slidably sleeved on the outer wall of the platform frame. A second bolt is threadedly connected to the outer wall of the sliding sleeve, and one end of the second bolt abuts against the platform frame.

[0007] In some embodiments, the support structure includes a housing fixedly connected to a connecting rod, and a threaded tube rotatably connected to the inner wall of the housing. A lead screw is threadedly connected to the inner wall of the threaded tube. One end of the lead screw passes through the housing and extends to the outside of the housing. A support assembly is threadedly connected to the other end of the lead screw located outside the housing. A strip groove is formed on the outer wall of the housing, and a limit block is slidably connected to the inner wall of the strip groove. One side wall of the limit block is fixedly connected to the lead screw. A circular hole is formed on the inner wall of the connecting rod, and a drive connector is disposed in the circular hole. A reinforcing rod is fixedly connected to the inner wall of the platform frame. A groove is formed on the upper surface of the reinforcing rod, and a drive assembly is disposed in the groove.

[0008] In some embodiments, the drive assembly includes a first rectangular rod disposed in a groove, and both ends of the first rectangular rod are fixedly connected to rotating blocks, and one end of the rotating block passes through the platform frame and extends to the outside of the platform frame.

[0009] In some embodiments, the drive connector includes a rotating shaft rotatably connected to the inner wall of a circular hole, with one end of the rotating shaft penetrating the housing and extending into the housing. A first gear is fixedly connected to one end of the rotating shaft inside the housing. A second gear is fixedly sleeved on the outer wall of the threaded tube, and the second gear meshes with the first gear. A rectangular hole is formed inside the rotating shaft, and a second rectangular rod is slidably connected to the inner wall of the rectangular hole. A limit frame is fixedly connected to the lower surface of the rod, and the limit frame is located inside a groove. A rectangular sleeve is rotatably connected to the inner wall of the limit frame. A third gear is rotatably connected to the outer wall of the slide rod. A fourth gear meshes with one side wall of the third gear, and a vertical bar is fixedly connected to one side wall of the fourth gear. One end of the vertical bar passes through the slide rod and extends into the slide rod. A fifth gear is fixedly connected to one end of the vertical bar inside the slide rod. A cavity is opened inside the slide rod, and a shaft is rotatably connected to the inner wall of the cavity. Both ends of the shaft pass through the cavity and extend into the slide groove. A sixth gear is fixedly sleeved on the outer wall of the shaft, and the sixth gear meshes with the fifth gear. The end of the shaft is fixedly connected to the second rectangular rod.

[0010] In some embodiments, the support assembly includes a support cap that is threadedly connected to a lead screw, and the outer wall of the support cap has a rotating hole.

[0011] In some embodiments, the outer wall of the lead screw is threaded with a fixing sleeve, the outer wall of the fixing sleeve is provided with anti-slip texture, and one side wall of the fixing sleeve abuts against the support cap.

[0012] In some embodiments, a support rod is fixedly connected to one side wall of the limiting block, and a roller is rotatably connected to one side wall of the support rod.

[0013] In some embodiments, one end of the rotating block located outside the platform frame has an internal hexagonal slot.

[0014] In some embodiments, the outer wall of the connecting rod is provided with a groove, and the groove is marked with scale lines.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Firstly, this solution uses a sliding rod and connecting rod to fix the support structure. When needed, the second bolt can be loosened, and the sliding rod can be slid to move the connecting rod and support structure, adjusting the longitudinal position of the support structure. Then, the first bolt can be loosened, and the connecting rod and support structure can be pulled to adjust the lateral position of the support structure, positioning it under the body-in-white. Finally, the first and second bolts can be tightened for fixation. This method allows for unrestricted adjustment; as long as the support position is within the adjustable stroke range of this device, it can be adjusted, making the device more practical.

[0017] Secondly, this solution uses a threaded tube and a lead screw in combination. When the threaded tube rotates, the lead screw and the support assembly move upward, thereby lifting the body-in-white. This allows the support assembly to lift the body-in-white, making it easier for the inspection device to reach into the gap between the body-in-white and the platform frame for inspection, thus facilitating the inspection process of this device.

[0018] Thirdly, this solution uses a drive assembly and drive connector to work together, allowing one drive assembly to simultaneously move multiple support structures upwards, thereby stabilizing the body-in-white. Furthermore, by using a rotating shaft, rectangular sleeve, and axle, the shaft and axle do not obstruct the adjustment of the support structure, whether it is adjusted laterally or longitudinally. After the support structure is adjusted, the drive connector can also connect the drive mechanism and the lead screw, ensuring that the drive assembly can drive the lead screw to move, thus completing the erection of the body-in-white.

[0019] Fourthly, this solution uses a combination of support rods and rollers to facilitate the movement of the device and the car body. During testing, as the car body is lifted and supported, the rollers automatically move upwards. After the rollers move upwards, the device loses the support of the rollers, causing the support frame to move downwards and contact the reference surface. This stabilizes the device during testing. Furthermore, due to the stable structure of the support frame, it can be manufactured with greater precision, ensuring that the support frame makes proper contact with the reference surface. This guarantees the accuracy of the device's support during testing and avoids testing errors caused by uneven support.

[0020] Fifthly, after the test, this solution can reverse the rotating block to allow the support component to move down and reset. When the support component moves down and resets, the roller moves down to support the device. In this way, the white body can be directly pushed to the next processing step by the roller for the next processing step, which is convenient and fast. When the support component moves down, the white body loses the support of the support component, causing the white body to move down, thereby reducing the height of the white body and lowering the center of gravity of the white body, so as to ensure the stability of the white body when pushing it away.

[0038] like Figures 1 to 9 As shown, a body-in-white support platform includes a platform frame 1. A support frame 2 is fixedly connected to the lower surface of the platform frame 1. Two slide rods 3 are slidably connected to the upper surface of the platform frame 1, and each end of the two slide rods 3 has a slide groove 4. A connecting rod 5 is slidably connected to the inner wall of the slide groove 4, and a support structure is fixedly connected to one end of the connecting rod 5. A first bolt 6 is threadedly connected to the outer wall of the slide rod 3, and one end of the first bolt 6 passes through the slide rod 3 and abuts against the connecting rod 5. A sliding sleeve 7 is fixedly connected to the lower surface of the slide rod 3, and the sliding sleeve 7 is slidably sleeved on the outer wall of the platform frame 1. A second bolt 8 is threadedly connected to the outer wall of the sliding sleeve 7, and one end of the second bolt 8 abuts against the platform frame 1.

[0039] As can be seen from the above structure, by setting up the sliding rod 3 and connecting rod 5 to fix the support structure, when needed, the second bolt 8 can be loosened, and then the sliding rod 3 can be slid to move the connecting rod 5 and the support structure, adjusting the longitudinal position of the support structure. Then, the first bolt 6 can be loosened and the connecting rod 5 and the support structure can be pulled to adjust the lateral position of the support structure, so that the support structure is located in the support position under the body-in-white. Subsequently, the first bolt 6 and the second bolt 8 can be tightened to fix it. In this way, the adjustment position is not limited. As long as the support position is within the adjustment stroke range of this device, the support position can be adjusted by this device, making this device more practical.

[0040] In some embodiments, the support structure includes a housing 9 fixedly connected to the connecting rod 5, and a threaded tube 10 is rotatably connected to the inner wall of the housing 9. A lead screw 11 is threadedly connected to the inner wall of the threaded tube 10. One end of the lead screw 11 passes through the housing 9 and extends to the outside of the housing 9. A support assembly is threadedly connected to one end of the lead screw 11 located outside the housing 9. A strip groove 12 is formed on the outer wall of the housing 9, and a limit block 13 is slidably connected to the inner wall of the strip groove 12. One side wall of the limit block 13 is fixedly connected to the lead screw 11. A circular hole 14 is formed on the inner wall of the connecting rod 5. A drive connector is provided inside the 4. A reinforcing rod 15 is fixedly connected to the inner wall of the platform frame 1. A groove 16 is provided on the upper surface of the reinforcing rod 15, and a drive assembly is provided in the groove 16. By setting a threaded tube 10 to cooperate with the lead screw 11, when the threaded tube 10 rotates, the lead screw 11 and the support assembly can move upward, thereby causing the support assembly to lift the body-in-white. This allows the support assembly to lift the body-in-white, so that when inspecting the body-in-white, the inspection device can easily be inserted into the gap between the body-in-white and the platform frame 1 for inspection, thus facilitating the inspection of this device.

[0041] In some embodiments, the drive assembly includes a first rectangular rod 17 disposed in the groove 16, and both ends of the first rectangular rod 17 are fixedly connected to rotating blocks 18, and one end of the rotating block 18 passes through the platform frame 1 and extends to the outside of the platform frame 1; by setting the rotating block 18 and the first rectangular rod 17 to cooperate, when rotating the rotating block 18 and the first rectangular rod 17, the threaded tube 10 can be driven to rotate by the drive connector.

[0042] In some embodiments, the drive connector includes a rotating shaft 20 rotatably connected to the inner wall of the circular hole 14, with one end of the rotating shaft 20 penetrating through the housing 9 and extending into the housing 9. A first gear 21 is fixedly connected to one end of the rotating shaft 20 located inside the housing 9. A second gear 22 is fixedly sleeved on the outer wall of the threaded tube 10, and the second gear 22 meshes with the first gear 21. A rectangular hole 23 is formed inside the rotating shaft 20, and a second rectangular rod 24 is slidably connected to the inner wall of the rectangular hole 23. A limit frame 25 is fixedly connected to the lower surface of the slide rod 3, and the limit frame 25 is located inside the groove 16. A rectangular sleeve is rotatably connected to the inner wall of the limit frame 25. 26, and the outer wall of the rectangular sleeve 26 is rotatably connected to a third gear 27. A fourth gear 28 meshes with one side wall of the third gear 27, and a vertical bar 29 is fixedly connected to one side wall of the fourth gear 28. One end of the vertical bar 29 passes through the slide rod 3 and extends into the interior of the slide rod 3. A fifth gear 30 is fixedly connected to one end of the vertical bar 29 located inside the slide rod 3. A cavity 38 is opened inside the slide rod 3, and a shaft 31 is rotatably connected to the inner wall of the cavity 38. Both ends of the shaft 31 pass through the cavity 38 and extend into the slide groove 4. A sixth gear 32 is fixedly sleeved on the outer wall of the shaft 31, and the sixth gear 32 and the fifth gear 30 are... The end of shaft 31 is fixedly connected to the second rectangular rod 24. By using a rotating shaft 20, rectangular sleeve 26, and shaft 31 in conjunction with each other, the rotating shaft 20 and shaft 31 will not obstruct the adjustment of the support structure, whether the support structure is adjusted laterally or longitudinally. After the support structure is adjusted, the drive connector can also connect the drive mechanism and the lead screw 11, ensuring that the drive assembly can drive the lead screw 11 to move. During drive, an internal hex wrench is used in conjunction with the internal hex socket 19 to rotate the rotating block 18, causing the rotating block 18 to drive the rectangular sleeve 26 and the third gear 27 to rotate. 7 drives the fourth gear 28, the vertical bar 29 and the fifth gear 30 to rotate. The rotating fifth gear 30 drives the sixth gear 32 to rotate. The rotating sixth gear 32 drives the shaft 31 to rotate. The rotating shaft 31 drives the second rectangular bar 24 to rotate. The rotating second rectangular bar 24 drives the rotating shaft 20 to rotate. The rotating shaft 20 drives the first gear 21 to rotate. The rotating first gear 21 drives the second gear 22 and the threaded tube 10 to rotate. Since the lead screw 11 is limited, when the threaded tube 10 rotates, the threaded tube 10 drives the lead screw 11 to move. The moving lead screw 11 drives the support assembly to move, thereby causing the support assembly to lift the body-in-white.

[0043] In some embodiments, the support assembly includes a support cap 33 threadedly connected to the lead screw 11, and the outer wall of the support cap 33 is provided with a rotating hole 34. By setting the support cap 33 and the rotating hole 34, a pin can be inserted into the rotating hole 34 to rotate the support cap 33, thereby adjusting the height of the support cap 33 and making fine adjustments to ensure that the multiple support caps 33 support the level of the body-in-white.

[0044] In some embodiments, a fixing sleeve 35 is threadedly connected to the outer wall of the lead screw 11. The outer wall of the fixing sleeve 35 is provided with anti-slip texture, and one side wall of the fixing sleeve 35 abuts against the support cap 33. By setting the fixing cap 35, the support cap 33 can be fixed and the support cap 33 can be prevented from rotating at will.

[0045] In some embodiments, a support rod 36 is fixedly connected to one side wall of the limiting block 13, and a roller 37 is rotatably connected to one side wall of the support rod 36. By setting the support rod 36 and the roller 37 to work together, it is convenient to push the device and the body-in-white to move. During the test, when the body-in-white is moved up and the body-in-white is supported, the roller 37 can automatically move up. After the roller 37 moves up, the device loses the support of the roller 37, causing the support frame 2 to move down and contact the reference surface. This can stabilize the device during the test. At the same time, because the structure of the support frame 2 is stable, it can be manufactured more precisely, so that the support frame 2 contacts the reference surface. This can ensure the accuracy of the device's support during the test and avoid the test error caused by uneven support of the device.

[0046] In some embodiments, one end of the rotating block 18 located outside the platform frame 1 is provided with an internal hexagonal slot 19; by providing the internal hexagonal slot 19, when rotating the rotating block 18, an internal hexagonal wrench can be used to cooperate with the internal hexagonal slot 19 to rotate the rotating block 18.

[0047] In some embodiments, the outer wall of the connecting rod 5 is provided with a groove 39, and the groove 39 is marked with a scale line 40; by setting the scale line 40, the length of the connecting rod 5 pulled out can be determined by the scale line 40, and thus the position of the longitudinal adjustment of the support structure can be determined.

[0048] In this invention, during use, the second bolt 8 can be loosened, and then the sliding rod 3 can be slid to move the connecting rod 5 and the support structure, adjusting the longitudinal position of the support structure. Then, the first bolt 6 can be loosened, and the connecting rod 5 and the support structure can be pulled to adjust the lateral position of the support structure, so that the support structure is located in the support position under the body-in-white. Subsequently, the first bolt 6 and the second bolt 8 can be tightened for fixation. In this way, the adjustment position is not limited. As long as the support position is within the adjustment stroke range of this device, the device can adjust the support position, making this device more practical.

[0049] After the device supports the body-in-white, the body-in-white can be moved to the required position for inspection using the rollers 37. Before inspection, an Allen wrench can be used in conjunction with the Allen socket 19 to rotate the rotating block 18, causing the rotating block 18 to drive the rectangular sleeve 26 and the third gear 27 to rotate. The rotation of the third gear 27 drives the fourth gear 28, the vertical bar 29, and the fifth gear 30 to rotate. The rotation of the fifth gear 30 drives the sixth gear 32 to rotate. The rotation of the sixth gear 32 drives the shaft 31 to rotate. The rotation of the shaft 31 drives the second rectangular bar 24 to rotate. The second rectangular rod 24 drives the rotating shaft 20 to rotate, the rotating shaft 20 drives the first gear 21 to rotate, the rotating first gear 21 drives the second gear 22 and the threaded tube 10 to rotate. Since the lead screw 11 is limited, when the threaded tube 10 rotates, the threaded tube 10 drives the lead screw 11 to move. The moving lead screw 11 drives the support assembly to move, thereby causing the support assembly to lift the body-in-white. This makes it easier for the detection device to insert into the gap between the body-in-white and the platform frame 1 for detection when inspecting the body-in-white, thus facilitating the detection of this device.

[0050] When the lead screw 11 moves upward, the upward-moving lead screw 11 drives the limit block 13, support rod 36 and roller 37 to move upward. After the roller 37 moves upward, the device loses the support of the roller 37, causing the support frame 2 to move downward and contact the reference surface. This can stabilize the device during testing. At the same time, because the structure of the support frame 2 is stable, it can be manufactured more precisely, so that the support frame 2 contacts the reference surface. This can ensure the accuracy of the device's support during testing and avoid testing errors caused by uneven support of the device.

[0051] After the inspection, the rotating block 18 can be reversed to allow the support component to move down and reset. When the support component moves down and resets, the roller 37 moves down to support the device. In this way, the white body can be directly pushed to the next processing step by the roller 37 for the next processing step, which is convenient and fast. When the support component moves down, the white body loses the support of the support component, causing the white body to move down, thereby reducing the height of the white body and lowering the center of gravity of the white body, so as to ensure the stability of the white body when pushing it away.

[0052] 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.
