Description

Technical Field

[0001] The utility model relates to the technical field of crankshaft processing, in particular to an automatic loading crankshaft quenching machine tool. Background Art

[0002] The crankshaft is the most important component in the engine. It bears the force transmitted from the connecting rod, and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, work evenly and have good balance. When the existing crankshaft quenching machine tool quenches the crankshaft, the staff needs to stay in front of the machine tool and frequently load the material manually, which not only greatly increases the workload of the staff, but also after the machine tool quenches the crankshaft, the ambient temperature is high, which can easily cause the staff to be burned when loading the material, causing safety accidents.

[0028] A loading assembly 4 for automatic loading is installed on the upper surface of the operating table 1;

[0029] A drainage groove 101 is provided in the middle of the upper surface of the operating table 1 .

[0030] When the crankshaft needs to be quenched, the staff uses the loading assembly 4 to move the crankshaft between the clamping drive assembly 2, and then the staff activates the clamping drive assembly 2 to clamp the crankshaft and rotate it. Then the staff controls the first electric guide rail 301, the cylinder 302 and the quencher 303 to quench the rotating crankshaft. Compared with the manual loading method, the staff does not need to stay in front of the machine tool to frequently load manually, which not only reduces the workload of the staff, but also avoids the staff from being burned during loading, causing safety accidents.

[0031] In another embodiment of the utility model, the clamping drive assembly 2 includes two hydraulic cylinders 201, which are respectively fixedly mounted on both sides of the upper surface of the operating table 1, and the output ends of the two hydraulic cylinders 201 are arranged opposite to each other. The output ends of the two hydraulic cylinders 201 are fixedly mounted with a moving plate 202, and the two moving plates 202 are rotatably mounted with a pin shaft 203 on the opposite side, and the two pin shafts 203 are fixedly mounted with a three-axis clamp 204 on the opposite end;

[0032] A first motor 205 is fixedly mounted on one side of one of the moving plates 202 away from the three-axis clamp 204, and an output shaft end of the first motor 205 passes through the corresponding moving plate 202 and is fixedly connected to the corresponding three-axis clamp 204;

[0033] The feeding assembly 4 includes two partitions 401, which are fixedly mounted on both sides of the upper surface of the operating table 1, respectively.

An electric push rod 404 is fixedly mounted on one side of the rotating plate 403, and a supporting plate 405 is fixedly mounted on the output end of the electric push rod 404. Two clamping claw cylinders 406 are arranged on one side of the supporting plate 405 close to the three-axis clamp 204, and clamping plates 407 are fixedly mounted on the moving ends of the two clamping claw cylinders 406.

[0034] A bracket 408 is fixedly installed on the side of the two partitions 401 away from the three-axis clamp 204, a horizontal plate 409 is fixedly installed between the two brackets 408, a cylinder 410 is fixedly installed on the lower surface of the horizontal plate 409, the output end of the cylinder 410 passes through the horizontal plate 409 and is fixedly installed with a mounting plate 4101, and fixed plates 411 are fixedly installed on both sides of the upper surface of the mounting plate 4101, and a plurality of limit blocks 412 are tiltedly arranged on the side of the two fixed plates 411 close to the three-axis clamp 204;

The moving end of the second electric guide rail 6 is fixedly installed with a rack 601, which meshes with the gear 4021.

[0036] The staff starts the second electric guide rail 6, so that its moving end drives the rack 601 to move. Under the meshing action of the moving rack 601 and the gear 4021, the rotating rod 402 rotates to drive the rotating plate 403 to rotate, so that the electric push rod 404 moves to the crankshaft position. Then the staff starts the electric push rod 404 and the clamping claw cylinder 406, and then controls the moving end of the second electric guide rail 6 to move in the opposite direction, so that the clamping plate 407 clamps the crankshaft and moves it between the two three-axis clamps 204. Then the staff starts the hydraulic cylinder 201, so that its output end drives the three-axis clamp 204 to move. Then the staff enables the three-axis clamp 204 to clamp the crankshaft. Then the staff controls the clamping plate 407 to reset. Then the staff starts the first motor 205, so that its output shaft drives the three-axis clamp 204 to rotate.

[0041] The staff rotates the rotating wheel 503 to drive the screw rod 502 to rotate. The rotating screw rod 502 drives the clamping cylinder 406 to move along the slide groove 5 by screwing in the thread, which makes it convenient for the staff to adjust the position of the clamping cylinder 406 according to the length of the crankshaft, thereby increasing practicality.

[0042] The working principle of this automatic loading crankshaft quenching machine:

[0043] When in use, the staff starts the second electric guide rail 6, so that its moving end drives the rack 601 to move. Under the meshing action of the moving rack 601 and the gear 4021, the rotating rod 402 rotates to drive the rotating plate 403 to rotate, so that the electric push rod 404 moves to the crankshaft position, and then the staff starts the electric push rod 404 and the clamping claw cylinder 406, and then controls the moving end of the second electric guide rail 6 to move in the opposite direction, so that the clamping plate 407 clamps the crankshaft and moves it between the two three-axis clamps 204. Then the staff starts the hydraulic cylinder 201, so that its output end drives the three-axis clamp 204 to move, and then the staff enables the three-axis clamp 204 to clamp the crankshaft, and then the staff controls the clamping plate 407 to reset, and then the staff starts the first motor 205, so that its output shaft drives the three-axis clamp 204 to rotate, and then the staff controls the first electric guide rail 301, the cylinder 302 and the quencher 303 to quench the rotating crankshaft.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
