Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, and more specifically, it relates to a quick positioning lifting tool for engine cylinder block production. Background Technique

[0002] The cylinder block is one of the most important parts of an automobile engine and even the automobile. The machining quality of the engine directly affects the quality of the engine, and further affects the overall quality of the automobile. Therefore, the manufacturing and machining of engine cylinder blocks have long been valued by automobile production enterprises at home and abroad. The engine cylinder block is the basic part and framework of the engine, and at the same time, it is also the basic part during the general assembly of the engine. After the production of the engine cylinder block, in order to ensure the quality of the cylinder block, it is necessary for workers to perform inspection operations on the cylinder block. In order to facilitate the workers to carry out the inspection, it is necessary to use a fixture to clamp and limit the cylinder block to assist the workers in the inspection operation;

[0003] In the related technology, a lifting tool for engine cylinder block machining realizes the clamping of the lifting tool on structures of different sizes through the mutual cooperation of a first motor, a second transmission rod, a gear, a rack, a limiting rod, a first fixing frame, a slider, a sliding rod, a hydraulic rod, a clamping arm and a clamping plate, avoiding the situation that the fixture can only clamp an engine cylinder block of a certain size and cannot be universal. Through the mutual cooperation of a second motor, a worm gear, a worm, a fixed base, a first transmission rod, a top plate and a bottom plate, the rotation function of the lifting tool is realized, avoiding the situation that the lifting tool can only fixedly clamp the engine cylinder block, reducing the movement of workers, reducing the workload of workers, and improving the work efficiency at the same time;

[0032] Embodiment 1:

[0033] Please refer to Figure 1 and Figure 3 , the present utility model provides a technical solution: a quick positioning sling for engine cylinder block production, including a fixed seat 1, a torsion bearing 2 is connected to the bottom of the fixed seat 1, and a movable shaft 3 is rotatably connected inside the torsion bearing 2; the bottom end of the movable shaft 3 is connected with a fixed block 4, and both sides of the bottom of the fixed block 4 are connected with a clamping assembly 5; the clamping assembly 5 includes two rotatable pushing frames 503, the bottoms of the two pushing frames 503 are both connected with a clamping part 504, and the two clamping parts 504 cooperate with each other; the clamping assembly 5 includes a fixed block 4 that can be lifted, and a plurality of telescopic protruding blocks 515 are arranged on the fixed block 4.

By adopting the above technical solution, through the first gear 6, the motor 7, the rotating shaft 8 and the second gear 9, during the process of lifting the cylinder block, the second gear 9 drives the first gear 6 to rotate, driving the movable shaft 3 to rotate inside the torsion bearing 2, thereby driving the cylinder block clamped at the bottom to rotate synchronously, cooperating with the staff to perform the alignment and installation operation on the cylinder block. Through the first electric push rod 507, the double-end telescopic bracket 509, the push frame 503 and the clamping part 504, the double-end telescopic bracket 509 is pushed to rise, driving the two push frames 503 to rotate on the two support frames 502, thereby driving the two clamping parts 504 to approach each other and clamping the middle cylinder block.

[0035] Embodiment 2:

[0036] On the basis of Embodiment 1, please refer to Figure 2 、 Figure 4 and Figure 5 .

[0037] Specifically, a support block 511 is connected to the bottom of the double-end telescopic bracket 509, a baffle 512 is connected to the bottom of the support block 511, a fixed frame 513 is connected to the bottom of the baffle 512, four sliding frames 514 are connected to the surface of the fixed frame 513, the four sliding frames 514 are evenly distributed on the fixed frame 513, an extension block 515 is slidably connected in each of the four sliding frames 514, a sliding block 516 is slidably connected in the fixed frame 513, four push blocks 517 are connected to the outer surface of the sliding block 516, the four push blocks 517 are evenly distributed on the sliding block 516, the four push blocks 517 are respectively in one-to-one correspondence and cooperation with the four extension blocks 515, a chute 518 is formed in the support block 511, a second electric push rod 519 is connected to the top of the chute 518, the output end of the second electric push rod 519 passes through the baffle 512 and is connected to the top of the sliding block 516, and a lifting ring 11 is connected to the top of the fixed seat 1. By adopting the above technical solution, after the fixed frame 513 is inserted into the cylinder body through the baffle 512 and the fixed frame 513, the baffle 512 can block, facilitating the extension of the extension block 515 on the inner wall of the fixed frame 513 to support the inner wall of the cylinder body, so as to cooperate with the clamping part 504 to fix and limit the cylinder body, making the lifting of the cylinder body more stable. Through the lifting ring 11, it is convenient to install the fixed seat 1 on the crane for operation and use.

[0038] The working principle of the utility model is as follows: during use, the staff installs the lifting ring 11 on the top of the fixed seat 1 on the crane. Through the operation of the crane, the lifting tool is lifted and moved above the engine cylinder block to be lifted, and then the crane operates to lower, driving the fixed seat 1 to descend. During the gradual descent of the fixed seat 1, the fixed frames 513 at the bottoms of the two clamping assemblies 5 are simultaneously aligned with the holes on the cylinder block, and the clamping parts 504 at the two sides of the bottom are respectively located on both sides of the cylinder block. During the continuous descent, the two fixed frames 513 synchronously enter the holes of the cylinder block. After the bottom of the baffle 512 contacts the top of the cylinder block, the fixed frame 513 stops descending, and the baffle 512 cannot enter the hole of the cylinder block. After the baffle 512 contacts the top of the cylinder block, the fixed seat 1 continues to descend, driving the clamping parts 504 on both sides to continue to descend. By operating through an external power supply and the first electric push rod 507, the first electric push rod 507 shortens, driving the locking clamp 508 to rise. The double-end telescopic bracket 509 fixed by the locking clamp 508 rises, driving the push frames 503 at both ends of the double-end telescopic bracket 509 to rotate on the support frame 502. During the rotation of the push frame 503 on the support frame 502, the two ends of the double-end telescopic bracket 509 gradually extend, so that the push frames 503 on both sides can smoothly rotate on the two support frames 502, driving the clamping parts 504 at the bottoms of the two push frames 503 to gradually approach. After the two clamping parts 504 at the bottom are close to both sides of the cylinder block, the crane stops working, the fixed seat 1 stops descending, the first electric push rod 507 stops working, and no longer drives the double-end telescopic bracket 509 to rise. The clamping plates on both sides stop rotating and clamp the cylinder block by approaching both sides of the cylinder block. After the clamping parts 504 on both sides approach the cylinder block and clamp it, the second electric push rod 519 operates. The second electric push rod 519 shortens, driving the sliding block 516 to slide and rise in the fixed frame 513, driving the push block 517 on the surface of the sliding block 516 to rise, pushing the protruding blocks 515 in the sliding frame 514, so that the surrounding protruding blocks 515 slide and extend in the sliding frame 514, supporting the inner wall of the cylinder block and assisting the clamping parts 504 to clamp the cylinder block. After the protruding blocks 515 contact the inner wall of the cylinder block, the second electric push rod 519 stops working.

[0039] After clamping the cylinder block, the crane works to drive the fixed seat 1 to rise, thereby driving the clamped cylinder block to rise and move to the assembly position. During the hoisting and installation process, according to requirements, the staff can control the motor 7 to work, drive the rotating shaft 8 to rotate, drive the second gear 9 to rotate in the limit groove 10, meshing to drive the first gear 6 to rotate, drive the movable shaft 3 to rotate in the torsion bearing 2, thereby driving the fixed block 4 at the bottom to rotate, driving the clamping assemblies 5 on both sides at the bottom to rotate, thereby driving the clamped cylinder block to rotate, assisting the staff in the installation operation of the engine. After the adjustment is completed, after placing the cylinder block down at a suitable position, the first electric push rod 507 extends, pushing the double-end telescopic bracket 509 to descend and shorten, driving the push frames 503 at both ends to rotate on the two support frames 502, driving the two clamping parts 504 to leave both sides of the cylinder block. The second electric push rod 519 extends, driving the sliding block 516 to slide and descend in the fixed frame 513, driving the push block 517 to descend, so that the push block 517 no longer exerts a thrust on the protruding block 515, so that the fixed block 4 can be smoothly pulled out of the hole of the cylinder block, and then the lifting tool is lifted, thereby clamping a new cylinder block again for operation.

[0040] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
