Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing, and more specifically, to a lifting tool for automobile manufacturing. Background Art

[0002] Lifting tools are mainly used for hoisting and transporting heavy objects, and play a key role in multiple links of automobile manufacturing. For example, in the stamping link and the general assembly link, various types of lifting tools are required to carry and transport various large components.

[0003] A commonly used lifting tool for automobile manufacturing in the prior art is a structure that clamps and lifts through a fixture. The fixture is controlled by a cylinder to clamp the automobile chassis, and a cross bar is also provided at the bottom of the fixture to prevent the automobile chassis from falling. Therefore, under the restriction of the cross bar, the automobile chassis clamped by the fixture can only be in a horizontal state for the assembly of components and assemblies. This also causes that when assembling components and assemblies close to the center of the automobile, the staff is easily blocked by the metal parts of the fixture, which is not convenient for assembly. A relatively common solution is to directly fix the automobile chassis on the moving table with bolts, so as to facilitate the installation of components and assemblies on the top or bottom surface of the automobile chassis onto the automobile chassis. However, this solution requires a large number of bolts to be installed when installing the automobile chassis, and after the components and assemblies on one side of the automobile chassis are installed, all the bolts need to be removed, and the automobile chassis needs to be turned over and then installed with bolts again, which is time-consuming and laborious and is not conducive to the efficiency of automobile manufacturing.

[0004] To solve the above problems, a new design that is more convenient for lifting the automobile chassis is needed. Summary of the Invention

[0018] As described above, the characteristics and advantages of a lifting tool for automobile manufacturing in the present invention are:

[0019] Through the setting of the turntable, after both ends of the vehicle chassis are fixed between the clamping plate and the rotating plate, the suspension slide rail drives the cantilever to move, causing the gear to contact and gradually mesh with the second rack, thereby driving the first rotating rod to rotate, causing the turntable to drive the vehicle chassis within the clamping plate and the rotating plate to rotate, realizing the rotation of the vehicle chassis during the assembly process, enabling the vehicle chassis to rotate into a vertically upward state, so that components and assemblies can be conveniently installed on the vehicle chassis from the side without the obstruction of metal parts, and there is no need for manual operation for rotation, saving time and effort, which is beneficial to improving the efficiency of vehicle manufacturing;

[0020] Through the setting of the second rack, the second racks are equidistantly arranged on the moving path of the gear. During the process of the suspension slide rail driving structures such as the cantilever to move forward, the gear intermittently meshes with the second rack, thereby causing the vehicle chassis between the rotating plate and the clamping plate to rotate intermittently in one direction. Thus, assembly points for different components and assemblies can be set on both sides of the moving path of the fixing frame. According to the vehicle chassis rotating to different angles, the components and assemblies that are convenient to assemble at this angle can be orderly installed on the chassis, saving time and effort;

[0021] Through the setting of the storage groove and the telescopic plate, the vehicle chassis can be conveniently placed on the unobstructed placement rack. Subsequently, when the suspension slide rail starts to drive the cantilever to move, under the meshing action of the gear and the first rack, the telescopic plate is driven to extend out of the storage groove. Then, the air cylinder drives the clamping plate to rise, enabling the clamping plate and the telescopic plate to cooperate to fix the vehicle chassis, thus completing the installation and fixation of the vehicle chassis without the need for manual screwing of bolts, saving time and effort;

[0022] Through the cooperation of the gear and the second rack, after all components and assemblies are installed on the vehicle chassis, the suspension slide rail drives the cantilever to move in the initial direction, causing the gear to contact the second rack and driving the first rotating rod to rotate in the reverse direction, enabling the moving ring to drive the telescopic plate to reset through the sliding traction rod, so that the telescopic plate returns to the storage groove, and the vehicle chassis can be removed from the top of the placement rack without the need for workers to loosen bolts one by one for disassembly. Moreover, the clamping plate can be opened when the placement rack opens upward without the need to support the bottom of the vehicle chassis when loosening the clamping plate, further improving the efficiency of vehicle chassis manufacturing.

The top of the movable shaft of the air cylinder 418 passing through the placing frame 320 is fixedly connected to a clamping plate 419.

[0041] Combined with the above embodiments, the following is the entire working process and working principle of the above embodiments:

[0042] The initial state is as follows:

[0043] The gear 309 is not in contact with the first rack 310, the first rotating rod 308 is not rotated, the turntable 307 is not rotated, the placement rack 320 is in a horizontal state, the two moving seats 410 are located at one end of the two reciprocating lead screws 409 away from the fourth rotating rod 408, the moving ring 414 is in contact with the turntable 307, the telescopic plate 417 is located in the receiving groove 416, the movable shaft of the air cylinder 418 does not extend, and the bottom surface of the clamping plate 419 fits with the placement rack 320.

[0044] The working state is as follows:

[0045] Placing the vehicle chassis:

[0046] When different components and assemblies need to be installed on the vehicle chassis, the two ends of the vehicle chassis are placed on the tops of the two placement racks 320. After being placed stably, the suspension slide rail 301 is started, so that the suspension slide rail 301 drives the cantilever 302 to move towards the direction of the first rack 310 through the internal conveyor belt.

[0047] Fixing the chassis:

[0048] The cantilever 302 drives the fixing frame 305 to move through the sling 303 and the hanger 304, so that the first rotating rod 308 provided on one side of the fixing frame 305 approaches the nearest first rack 310 until the gear 309 at the top of the first rotating rod 308 meshes with the first rack 310, causing the first rotating rod 308 to drive the worm 312 to rotate under the action of the first rack 310, thereby driving the worm gear 315 to rotate. When the worm gear 315 rotates, it synchronously drives the first pulley 401 to rotate. During this process, the worm gear 315 drives the first ratchet 314 at Figure 5In the middle state, it rotates clockwise, causing the first ratchet wheel 314 to continuously push aside the first pawl 316. Therefore, the first ratchet wheel 314 does not drive the first runner 313 to rotate. Instead, the first pulley 401 drives the third rotating rod 402 to rotate through the belt and the second pulley 403. The third rotating rod 402 drives the second ratchet wheel 405 to rotate. The second ratchet wheel 405 rotates clockwise in the state shown in Figure 4, and thus drives the second runner 404 to rotate through the cooperation between the second ratchet wheel 405 and the second pawl 406. Furthermore, the fourth rotating rod 408 fixedly connected to the second runner 404 drives the reciprocating lead screw 409 to rotate. Since the moving seat 410 is in the initial state at this time and is located at the position of the reciprocating lead screw 409 close to the turntable 307, the reciprocating lead screw 409 drives the two moving seats 410 to move away from the turntable 307 through the double-thread, thereby driving the arc-shaped block 412 to move synchronously through the vertical frame 411. Furthermore, the arc-shaped block 412 drives the rotating ring 413 and the moving ring 414 to move until the moving seat 410 moves to one end of the reciprocating thread of the reciprocating lead screw 409 close to the fourth rotating rod 408. At this time, the moving ring 414 drives the telescopic plate 417 to slide out of the storage groove 416 through the traction rod 415 until most of the telescopic plate 417 slides out of the storage groove 416 and the end away from the traction rod 415 remains in the storage groove 416. At this time, the air cylinder 418 starts and pushes the clamping plate 419 to rise, so that the clamping plate 419 cooperates with the telescopic plate 417 to fix the vehicle chassis.

[0049] Rotary assembly:

[0050] After both ends of the vehicle chassis are fixed between the clamping plate 419 and the telescopic plate 417, the suspension slide rail 301 continues to drive the cantilever 302 to move, causing the gear 309 to disengage from the first rack 310 and contact and gradually engage with the second rack 311, thereby driving the first rotating rod 308 to rotate reversely, so that the first rotating rod 308 drives the worm wheel 315 to rotate through the worm 312 at the bottom, causing the worm wheel 315 to drive the first ratchet wheel 314 to rotate counterclockwise in the Figure 5 middle state, so that the first ratchet wheel 314 cooperates with the first pawl 316 to drive the first runner 313 to rotate, and further drives the second rotating rod 317 to rotate, so that the second rotating rod 317 drives the two first sprockets 318 to rotate, thereby driving the second sprocket 319 to rotate through the chain, so that the second sprocket 319 drives the turntable 307 to rotate through the rotating shaft 306. During this process, the second ratchet wheel 405 will continuously push aside the second pawl 406, so that the second runner 404 will not rotate, thereby driving the vehicle chassis in the clamping plate 419 and the telescopic plate 417 to rotate through the turntable 307. When the turntable 307 rotates, the moving ring 414 and the rotating ring 413 rotate synchronously with the turntable 307. The rotating ring 413 rotates through the sliding cooperation with the arc-shaped block 412, thus realizing the rotation of the vehicle chassis without manual operation, which is convenient for the assembly of the vehicle chassis.

[0051] Intermittent rotation:

[0052] After the gear 309 contacts and meshes with the second rack 311, the gear 309, the first rotating rod 308, the worm 312, the worm gear 315, the first sprocket 318, the chain and the second sprocket 319 will drive the turntable 307 to rotate, causing the vehicle chassis to rotate. Since the connecting frames 2 are equidistantly arranged on the hanging beam 1, the second rack 311 is equidistantly arranged on the moving path of the gear 309. Thus, during the process of the suspension slide rail 301 driving the structures such as the cantilever 302 forward, the gear 309 intermittently meshes with the second rack 311, causing the vehicle chassis between the telescopic plate 417 and the clamping plate 419 to rotate intermittently in one direction. Therefore, assembly points for different components and assemblies can be set on both sides of the moving path of the fixing frame 305. According to the vehicle chassis rotating to different angles, the components and assemblies that are convenient to assemble at this angle can be orderly installed on the chassis, saving time and effort.

[0053] Prevent loosening:

[0054] When the gear 309 meshes with the second rack 311 and causes the first rotating rod 308 to rotate, the worm 312 drives the worm gear 315 and the first pulley 401 to rotate, causing the first pulley 401 to drive the second pulley 403, the third rotating rod 402 and the second ratchet 405 to rotate through the belt. However, at this time, the second ratchet 405 rotates counterclockwise in Figure 4 and cannot drive the second runner 404 to rotate, thus not driving the connecting rod 407, the fourth rotating rod 408 and the reciprocating lead screw 409 to rotate. Therefore, the telescopic plate 417 and the clamping plate 419 continuously clamp the vehicle chassis during the rotational assembly process.

[0055] Remove the vehicle chassis:

[0056] After all the components and assemblies are installed on the vehicle chassis, the suspension slide rail 301 drives the cantilever 302 to move in the initial direction, causing the gear 309 to contact the first rack 310 on the connecting frame 2 at the other end of the hanging beam 1 and driving the first rotating rod 308 to rotate in the reverse direction. Thus, through the worm 312, the worm gear 315, the first pulley 401, the belt, the second pulley 403, the third rotating rod 402, the second ratchet 405, and the second pawl 406, the second runner 404 is driven to rotate. Therefore, the connecting rod 407 and the fourth rotating rod 408 drive the reciprocating lead screw 409 to rotate, causing the two moving seats 410 to slide towards the side close to the turntable 307 under the action of the reciprocating thread, thereby driving the vertical frame 411, the arc-shaped block 412, the rotating ring 413 and the moving ring 414 to reset. The moving ring 414 drives the telescopic plate 417 back into the storage groove 416 through the traction rod 415, and the vehicle chassis can be removed from the top of the placement rack 320. There is no need for workers to loosen the bolts one by one for disassembly. And compared with the method of using a fixture, there is no need to set a support at the bottom of the vehicle chassis when the telescopic plate 417 resets, further improving the efficiency of vehicle chassis manufacturing.

[0057] The above are only embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
