Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

A transmission push rod 22 is movably connected inside the first cylinder 21. The other end of the transmission push rod 22 is movably connected to a bearing platform 23. Docking blocks 24 are fixedly installed on both sides of the bearing platform 23. Support rods 25 are fixedly installed on the upper surface of the bearing platform 23. The top of the support rod 25 is fixedly connected to a first limit plate 26. A positioning rod 27 is fixedly installed on the top of the first limit plate 26.

A transfer rod 210 is fixedly connected to the lower surface of the second limit plate 29. The transfer rod 210 is located at the center of the second limit plate 29. The bottom of the transfer rod 210 is fixedly connected to a calibration platform 211. The transfer rod 210 passes through the bearing platform 23. A through hole 212 is opened at the junction of the bearing platform 23 and the transfer rod 210. Second cylinders 213 are fixedly connected to both sides of the second limit plate 29. The bottom of the second cylinder 213 is fixedly connected to the upper surface of the bearing platform 23. A transfer ring 214 is fixedly installed on the top of the calibration platform 211. The transfer ring 214 is located at the center of the calibration platform 211. A first calibration rod 216 is fixedly installed on the lower surface of the calibration platform 211.

[0038] In this embodiment, the calibration device 2 calibrates the vehicle frame assembly through the calibration platform 211 and the first calibration rod 216 and the second calibration rod 215 located thereon. Before calibration, the vehicle frame assembly needs to be placed on the auxiliary positioning device 3. Subsequently, the first cylinder 21 pushes the bearing platform 23 downward through the transmission push rod 22 to approach the vehicle frame to be detected.

The second calibration rod 215 can move along the direction of the first calibration rod 216 to perform precise secondary adjustment of the calibration range. The reference benchmark 219 on the positioning block 217 can determine the rotation range of the calibration platform 211.

[0045] Example 4

[0046] like Figures 1-8 As shown, the auxiliary positioning device 3 includes a bearing base plate 31, a positioning platform 32 is movably installed on the top of the bearing base plate 31, third cylinders 33 are fixedly connected to both sides of the positioning platform 32, one end of the piston rod of the third cylinder 33 is fixedly connected to the positioning base 34, a telescopic column 35 is fixedly installed on the upper surface of the positioning base 34, the top of the telescopic column 35 is fixedly connected to the lower surface of the bearing base plate 31, a protective frame 38 is fixedly installed at the edge of the positioning base 34, a hollow sleeve 36 is fixedly installed on one side of the bearing base plate 31, a guide rod 37 is fixedly installed on one side of the positioning base 34, the hollow sleeve 36 is sleeved on the outer wall of the guide rod 37, a positioning piece 39 is fixedly installed on one side of the protective frame 38, a transfer block 310 is fixedly installed on the other side of the positioning piece 39, the other end of the transfer block 310 is rotatably connected to a rectangular limit block 311, and a spare cylinder 312 is fixedly connected to one side of the rectangular limit block 311.

[0047] In this embodiment, the bearing base plate 31 directly determines the position of the positioning platform 32, and the position of the bearing base plate 31 can be controlled by the third cylinder 33. The piston rod of the third cylinder 33 is connected to the positioning base 34. When the piston rod moves, it can push the bearing base plate 31 to move along the direction of the telescopic column 35 to further expand the distance between the proofreading platform 211 and the positioning platform 32, so that the frame assembly can be placed in various postures and angles to facilitate a comprehensive inspection of the frame assembly. During the movement of the bearing base plate 31, the hollow sleeve 36 will move along the direction of the guide rod 37 to avoid misalignment, and the positioning piece 39 can determine the position of one end of the spare cylinder 312 to further raise the height of the bearing base plate 31. When in use, the spare cylinder 312 can be pushed to rotate around the adapter block 310, and the rectangular limit block 311 will move inside the adapter block 310 to avoid bending.

[0048] The device and its working principle: when in use, the frame assembly is first placed on the positioning platform 32.

Then the first cylinder 21 pushes the bearing platform 23 downward through the transmission push rod 22 to approach the frame to be tested. The moving range of the transmission push rod 22 is the initial movable range of the bearing platform 23, and the specific moving route is limited by the positioning rod 27. Then the second cylinder 213 pushes the second limit plate 29 to move downward along the direction of the transmission rod 28. When the limit plate 29 moves downward, the calibration platform 211 can be pushed downward by the transfer rod 210, so that the calibration platform 211 moves again based on the initial moving distance, so as to be closer to the frame assembly. The top positioning plate 4 directly determines the position of the first cylinder 21, and is connected to the support platform 6 through the support frame 5 to ensure the overall structural stability. The positioning frame 7 is used to install the control cabinet 1, and the limit guide rail 9 on the reinforcement support rod 8 can determine the moving route of the slider 10. The slider 10 is connected to the docking blocks 24 on both sides of the bearing platform 23 to ensure To ensure the stability of the carrying platform 23 when it moves, the first adjustment cylinder 220 can be used to push the proofreading platform 211 to rotate in one direction through the first extension protrusion 221, and the second adjustment cylinder 222 can be used to push the proofreading platform 211 to rotate in another direction through the second extension protrusion 223, so that the proofreading platform 211 can rotate within a certain range, thereby ensuring that each proofreading rod can correct one side of the frame, and the second proofreading rod 215 can move along the direction of the first proofreading rod 216, so as to make accurate secondary adjustments to the proofreading range.
