Description

Technical Field

[0001] This invention relates to the field of vehicle inspection tools for dismantled parts, and more specifically, to a flipping device for inspecting dismantled parts. Background Technology

[0002] When performing repair and inspection on engines from salvaged parts, it is necessary to adjust them to different positions to complete a comprehensive inspection. At this time, using a specialized tilting device to drive the engine to tilt allows repair personnel to visually inspect the condition of various parts of the engine. At the same time, this tilting function greatly facilitates subsequent disassembly and assembly operations, making it an indispensable auxiliary tool in the engine repair process.

[0003] Existing tilting frames mostly use worm gears to drive the shaft to adjust the engine angle and rely on their self-locking characteristics to maintain posture stability. However, after long-term use, the worm gear pair wears down, resulting in increased meshing clearance and a large amount of free play. This not only makes it difficult for the engine to maintain stability but also reduces the accuracy of tilting angle adjustment.

[0004] Furthermore, during engine maintenance and inspection, poor communication among operators could lead to the engine being accidentally rotated. If tools are left between the engine and the tilting frame, continued rotation could cause the tools to jam, resulting in damage to both the engine casing and the tools, posing a significant safety hazard.

[0005] In view of this, we propose a flipping device for the inspection of disassembled vehicle parts. Summary of the Invention

[0006] (a) Technical problems to be solved To address the problems existing in the prior art, the present invention provides a flipping device for the inspection of disassembled vehicle parts, in order to solve the technical problem mentioned in the background art, which is that the wear of the worm gear and worm shaft causes a large amount of free stroke, resulting in engine instability and reduced adjustment accuracy.

An anti-accidental touch mechanism is provided on one side of the column, and the anti-accidental touch mechanism drives the worm gear to rotate; An anti-crushing mechanism is disposed between the base and the column.

[0008] Furthermore, both the piston chamber of the hydraulic motor and the oil guide pipe are filled with hydraulic oil, and there are no air bubbles in the hydraulic oil in the piston chamber of the hydraulic motor and the oil guide pipe.

[0009] Furthermore, the anti-accidental touch mechanism includes: Spline column one is fixedly connected to the worm gear. A spline sleeve is splinedly connected to the spline column one. The spline sleeve is slidably connected to the column. A handle is fixedly connected to the spline sleeve. Spring one is located inside the spline sleeve, and the two ends of spring one are respectively fixed to the spline post and the spline sleeve; Valve 2 is fixed to the inner wall of the column. Valve 2 is connected in series with the oil guide pipe. The rotating part of valve 2 is fixed to a fixing column 1.

[0010] Furthermore, the spline sleeve is rotatably connected to a rotating ring, the rotating ring is fixedly connected to a guide member, the guide member has a through groove in the middle, and the fixing post slides within the through groove of the guide member.

[0011] Furthermore, the anti-crushing mechanism includes: Valve 3 is fixed to the inner wall of the column. Valve 3 is connected in series with the oil guide pipe. The rotating part of valve 3 is fixed to fixed column 2. A hydraulic telescopic rod is fixed to the inner wall of the column. A guide member is fixed to the telescopic end of the hydraulic telescopic rod. A through groove is opened in the middle of the guide member. The fixed column slides in the through groove of the guide member.

[0012] Furthermore, the base is fixedly connected to a second hydraulic telescopic rod, the telescopic end of the second hydraulic telescopic rod is fixedly connected to a support plate, and the telescopic end of the second hydraulic telescopic rod is fitted with a second spring.

[0013] Furthermore, the base is fixedly connected to four symmetrically distributed guide pillars, and a tray is detachably connected between the four guide pillars. The first hydraulic telescopic rod and the second hydraulic telescopic rod are fixedly connected and connected by an oil pipe, and both the second hydraulic telescopic rod and the connected oil pipe are filled with hydraulic oil.

[0014] Furthermore, it also includes an installation mechanism disposed on the support shaft, the installation mechanism fixing the disassembled parts, the installation mechanism comprising: The movable column has a blind hole in the middle of the support shaft, and the movable column is slidably connected to the blind hole of the support shaft. The movable column has a stepped surface, and a spline column two is fixedly connected to the movable column. The spline column two is splinedly connected to the support shaft.

[0017] (III) Beneficial Effects Compared with the prior art, the present invention provides a flipping device for inspecting disassembled vehicle parts, which has the following advantages: 1. By combining a hydraulic motor with a worm gear drive, rigid locking is achieved using the incompressibility of hydraulic oil. When the valve is closed, the hydraulic motor shaft is locked, thus forming a reliable constraint on the support shaft. This effectively avoids the problems of unstable engine posture and decreased adjustment accuracy caused by long-term wear of the worm gear and resulting idle stroke, thereby improving the positioning accuracy and load-bearing stability of the tilting device.

[0018] 2. An anti-accidental-touch mechanism is installed at the worm gear drive end, controlling the opening and closing of valve two through the axial movement of the spline sleeve. During operation, valve two must be opened by pushing or pulling the handle before the worm gear can be rotated; after releasing the handle, valve two automatically closes, and then valve one can be manually closed. This design enforces a safe sequence in the operation process, eliminating the risk of the support shaft overturning due to accidental contact or misoperation of the handle, thus improving operational safety.

[0019] 3. A linkage protection system is formed by the hydraulic telescopic rod under the pallet and valve three connected in series in the hydraulic circuit. When a tool or other foreign object accidentally gets stuck between the engine and the pallet, the pallet is pressed down, driving the hydraulic telescopic rod to extend. This quickly closes valve three through the guide, locking the hydraulic motor and stopping the support shaft immediately. This mechanism achieves automatic response and emergency braking in the event of a crushing accident, effectively preventing damage to the engine housing and tools, and ensuring the safety of equipment and personnel.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] This invention provides a flipping device for inspecting disassembled vehicle parts, such as... Figures 1-5 As shown, it includes: base 1, column 2, support shaft 3, worm gear 4, support plate 5, worm 6, connecting frame 7, hydraulic motor 8, valve 1 9, connecting parts, anti-accidental contact mechanism and anti-crushing mechanism; A base 1 is fixedly connected to a column 2, which is rotatably connected to a support shaft 3. A worm gear 4 is fixedly connected to the support shaft 3. Two support plates 5 are fixedly connected to the column 2, and a worm 6 is rotatably connected between the two support plates 5. The worm 6 meshes with the worm gear 4. A connecting frame 7 is fixedly connected inside the column 2, and a hydraulic motor 8 (the hydraulic motor 8 is an existing mechanical structure, and its specific internal structure is not shown in the attached drawings) is fixedly connected to the column 2. The hydraulic motor 8 and the valve 9 are connected in series through an oil guide pipe 10, which is filled with hydraulic oil. An anti-accidental contact mechanism is located on one side of the column 2, which drives the worm 6 to rotate. An anti-extrusion mechanism is located between the base 1 and the column 2. The piston chamber of the hydraulic motor 8 and the oil guide pipe 10 are both filled with hydraulic oil, and there are no air bubbles in the hydraulic oil in the piston chamber of the hydraulic motor 8 and the oil guide pipe 10.

[0026] The disassembled engine is installed on the support shaft 3. Rotating the worm gear 6 drives the worm wheel 4, which in turn rotates the support shaft along the column 2. During the rotation of the support shaft 3, the support shaft drives the shaft of the hydraulic motor 8 to rotate. As the shaft of the hydraulic motor 8 rotates, the piston inside the hydraulic motor 8 reciprocates, causing the hydraulic oil to circulate along the guide pipe 10. The hydraulic motor 8 is a standard structure, and its working principle will not be elaborated here. In the initial state, valve 9 is open, and the hydraulic oil in the guide pipe 10 flows along the guide pipe 10. When the support shaft 3 rotates to the appropriate angle, valve 9 is closed. After valve 9 is closed, the hydraulic oil can no longer flow along the oil guide pipe 10. When the hydraulic oil stops flowing, the volume of the working chamber of the hydraulic motor 8 can no longer change. Therefore, the shaft of the hydraulic motor 8 cannot rotate. The shaft of the hydraulic motor 8 limits the support shaft 3, preventing the support shaft 3 from rotating. The hydraulic motor 8, in conjunction with the worm gear 4 and worm 6, locks the support shaft 3, preventing the worm gear 4 and worm 6 from wearing and causing a large free stroke, thus improving the stability of the support shaft 3 and the engine on it.

[0027] like Figure 4 and Figure 6 As shown, the anti-accidental touch mechanism includes: spline post 11, spline sleeve 12, spring 13, valve 14, fixed post 15, rotating ring 16, and guide member 17. Spline column 11 is fixed to worm gear 6. Spline column 11 is splinedly connected to spline sleeve 12. Spline sleeve 12 is slidably connected to column 2. A handle is fixedly connected to spline sleeve 12. Spring 13 is located inside spline sleeve 12. The two ends of spring 13 are fixedly connected to spline column and spline sleeve 12 respectively. Valve 2 14 is fixedly connected to the inner wall of column 2. Valve 2 14 is connected in series with oil guide pipe 10. Fixed column 15 is fixedly connected to the rotating part of valve 2 14. Spline sleeve 12 is rotatably connected to rotating ring 16. Rotating ring 16 is fixedly connected to guide member 17. A through groove is provided in the middle of guide member 17. Fixed column 15 slides in the through groove of guide member 17.

[0028] Pushing the handle on the spline sleeve 12 causes the spline sleeve 12 to slide along the spline post 11, compressing the spring 13. The spline sleeve 12 then moves the rotating ring 16. In the initial state, valve 14 is closed. The rotating ring 16 moves the guide 17, which in turn moves the fixed post through the through groove, opening valve 14. Then, rotating the handle on the spline sleeve 12 causes the spline sleeve 12 to rotate the worm gear 6 through the spline post 11, thereby driving the support shaft 3 to rotate. When the handle on the spline sleeve 12 is released, the spring force of the spring 13 causes the spline sleeve 12 to reset the connecting ring, which in turn resets the guide 17, closing valve 14. Then, manually closing valve 9 allows valve 14 to open through the movement of the spline sleeve 12, preventing accidental rotation of the handle on the spline sleeve 12 and potential serious safety accidents.

[0029] like Figure 5 , Figures 7-9 As shown, the anti-pinch mechanism includes: valve 3 18, fixed column 2 19, hydraulic telescopic rod 1 20, guide 2 21, hydraulic telescopic rod 2 22, support plate 23, spring 2 24, guide column 25 and tray 26; Valve 18 is fixed to the inner wall of column 2 and is connected in series with oil guide pipe 10. Valve 9, valve 14, and valve 18 are all existing parts and will not be described in detail here. The rotating part of valve 18 is fixed to fixed post 19. Hydraulic telescopic rod 20 is fixed to the inner wall of column 2. The telescopic end of hydraulic telescopic rod 20 is fixed to guide member 21. A through groove is opened in the middle of guide member 21, and fixed post 19 slides in the through groove of guide member 21. Hydraulic telescopic rod 22 is fixed to the base 1. The telescopic end of the hydraulic telescopic rod 22 is fixedly connected to a support plate 23, and the telescopic end of the hydraulic telescopic rod 22 is fitted with a spring 24; the base 1 is fixedly connected to four symmetrically distributed guide posts 25, and a tray 26 is detachably connected between the four guide posts 25; an oil pipe is fixedly connected and connected between the hydraulic telescopic rod 1 20 and the hydraulic telescopic rod 22; both the hydraulic telescopic rod 22 and the connected oil pipe are filled with hydraulic oil; the hydraulic telescopic rod 1 20 and the hydraulic telescopic rod 22 are existing structures, and their internal structures are not shown in the attached drawings.

[0030] In the initial state, tray 26 is placed between the four guide posts 25. Tray 26 is used to collect engine oil dripping from the engine. Under the elastic force of spring 24, the telescopic end of hydraulic telescopic rod 22 supports tray 26 through support plate 23. Valve 3 18 is initially in the open state. However, if communication between operators is not timely when rotating spline sleeve 12 to drive support shaft 3, the tool may fall off the engine and become stuck between tray 26 and the engine. Continued rotation of support shaft 3 will damage the tool and engine casing. When tray 26 is compressed, tray 26 moves along the four guide posts 25. As column 25 moves downward, tray 26 presses the telescopic end of hydraulic telescopic rod 22, spring 24 is compressed, and the telescopic end of hydraulic telescopic rod 22 retracts. Hydraulic oil in hydraulic telescopic rod 22 flows along the oil pipe into hydraulic telescopic rod 20, causing the telescopic end of hydraulic telescopic rod 20 to drive guide 21 to move downward. Guide 21 drives fixed column 19 to move through the through groove, causing valve 3 18 to close urgently. The rotating shaft of hydraulic motor 8 cannot rotate, thereby locking support shaft 3 in an emergency to prevent support shaft 3 from continuing to rotate and causing the falling tool to jam the engine, resulting in damage to the tool and engine housing.

[0031] like Figure 10 and Figure 11 As shown, it also includes an installation mechanism, which is mounted on the support shaft 3. The installation mechanism secures the disassembled parts. The installation mechanism includes: a moving column 27, a spline column 28, a cover plate 29, a connecting plate 30, a mounting plate 31, a guide shell 32, a wedge block 33, a sliding rod 34, and a spring 35. A blind hole is provided in the middle of the moving column 27 supporting the shaft 3. The moving column 27 is slidably connected to the blind hole of the supporting shaft 3. The moving column 27 is provided with a stepped surface. A spline column 28 is fixedly connected to the moving column 27. The spline column 28 is splinedly connected to the supporting shaft 3. The cover plate 29 is bolted to the supporting shaft 3. The moving column 27 passes through the cover plate 29 and the two are slidably connected. A connecting plate 30 is fixedly connected to the moving column 27. A mounting plate 31 is bolted to the connecting plate 30. The mounting plate 31 has multiple through slots. A guide shell 32 is fixedly connected to the supporting shaft 3. A wedge block 33 is slidably connected to the guide shell 32. The wedge block 33 passes through the supporting shaft 3 and limits the stepped surface of the moving column 27. A sliding rod 34 is slidably connected to the guide shell 32. The sliding rod 34 is fixedly connected to the wedge block 33. A spring 35 is fixedly connected between the wedge block 33 and the guide shell 32.

[0032] During engine installation, the mounting plate 31 is removed from the connecting plate 30, and then the mounting plate 31 is fixed to the engine with bolts. The engine is then lifted using lifting equipment, and the mounting plate 31 is positioned facing the connecting plate 30. The wedge block 33 is then pulled outward, causing it to slide along the guide shell 32. The wedge block 33 releases its restriction on the moving column 27, which then slides along the cover plate 29. The splined column 28 loses its spline connection with the support shaft 3, and the moving column 27 moves the connecting plate 30 closer to the mounting plate 30. Mounting plate 31, the bolts on mounting plate 31 are passed through connecting plate 30 and connected. During the above process, moving column 27 can rotate circumferentially within support shaft 3, thereby improving the installation efficiency of fixing mounting plate 31 and connecting plate 30. Then, the engine is pushed to make moving column 27 drive spline column 28 to move. Then, the worm gear 6 is rotated to make support shaft 3 rotate until spline column 28 and support shaft 3 are splined again. Under the elastic force of spring 35, wedge block 33 is reset and the moving column 27 is limited.

[0033] Working principle of the invention: During operation, rotating the worm gear 6 drives the worm wheel 4, causing the support shaft 3 and the disassembled parts on it to rotate around the column 2. The worm gear 6 is assisted in locking by the hydraulic motor 8: the rotating shaft of the hydraulic motor 8 is linked to the support shaft 3, and its piston chamber and oil guide pipe 10 are filled with air-free hydraulic oil, with a normally open valve 9 connected in series in the oil guide pipe 10. When the support shaft 3 rotates, it drives the rotating shaft of the hydraulic motor 8 to rotate, forcing the hydraulic oil to circulate in the oil guide pipe 10; when the support shaft 3 rotates to the required angle, the valve 9 is closed, the hydraulic oil circulation is interrupted, the working chamber volume of the hydraulic motor 8 is locked, and the rotating shaft cannot rotate, thus achieving rigid locking of the support shaft 3, avoiding the idle stroke caused by the wear of the worm wheel 4 and worm gear 6, and improving positioning stability.

[0034] To prevent accidental rotation of the support shaft 3 due to unintended contact, an anti-accidental contact mechanism is installed at the end of the worm gear 6. Under normal conditions, valve 14, connected in series with the oil guide pipe 10, is closed. During operation, the handle on the spline sleeve 12 must first be pushed, causing the spline sleeve 12 to compress the spring 13 and slide along the spline post 11. Simultaneously, this moves the rotating ring 16 and the guide member 17. The through groove of the guide member 17 moves the fixed post 15, opening valve 14. Rotating the handle then drives the spline sleeve 12 through the spline post 11, causing the support shaft 3 to rotate. Releasing the handle resets the spring 13, automatically closing valve 14. Valve 9 can then be manually closed. This design ensures that the worm gear 6 can only be operated after actively opening valve 14, preventing accidental contact and potential safety accidents.

[0035] Under normal conditions, valve 318 is open, and hydraulic telescopic rod 22, under the action of spring 24, supports tray 26 (used to collect engine oil) via support plate 23. If a tool falls and becomes stuck between the engine and tray 26 during the rotation of support shaft 3, tray 26 is pressed down along guide post 25, compressing hydraulic telescopic rod 22. The hydraulic oil inside enters hydraulic telescopic rod 120 through the oil pipe, causing hydraulic telescopic rod 120 to extend and drive guide member 21 down. The through groove of guide member 221 moves fixing post 29, quickly closing valve 318, locking hydraulic motor 8, and stopping support shaft 3 in an emergency, thus preventing damage to tools and engine housing.

[0036] To facilitate the installation of disassembled parts, a movable mounting mechanism is provided on the support shaft 3. Before installation, the mounting plate 31 is removed from the connecting plate 30 and fixed to the engine. The mounting plate 31 is aligned with the connecting plate 30 using a lifting device. The wedge block 33 is pulled outward to compress the spring 35, releasing the restriction on the stepped surface of the moving column 27. After the moving column 27 is unrestrained, it slides along the cover plate 29 (the spline column 28 disengages from the spline connection with the support shaft 3), bringing the connecting plate 30 closer to the mounting plate 31 for quick bolt connection. After installation, the engine is pushed to reset the moving column 27 until the spline column 28 re-spline-fits the support shaft 3. At the same time, the wedge block 33 resets and locks the moving column 27 under the action of the spring 35, ensuring reliable fixing of the disassembled parts.

[0037] In all the solutions mentioned above, for connections between two components, welding, bolt and nut connection, bolt or screw connection, or other known connection methods can be selected according to the actual situation. These will not be elaborated here. For all fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
