Description

Technical Field

[0001] This invention relates to the field of generator processing technology, specifically a tightening device for processing automotive generators. Background Technology

[0002] An automotive alternator (usually referring to an AC alternator) is a core component of a vehicle's electrical system, primarily responsible for supplying power to onboard electrical appliances and charging the battery when the engine is running. During the machining of an automotive alternator, a tightening device is needed to limit the pulley's position, ensuring the nut connects to the rotor shaft.

[0003] A search revealed a Chinese patent with application number "CN202223479324.7", which specifically describes a tightening device for processing automotive generators. The device housing has a fixed sleeve at its lower part, and a nut sleeve at its lower part. The fixed sleeve has an internal cavity into which the nut sleeve is inserted. Symmetrically arranged on both sides of the nut sleeve are spring-loaded chambers, each containing a pressure plate. A first spring is fixedly installed on one side of the pressure plate, a pressure head is fixedly installed at the lower end of the other side of the pressure plate, and a connector plate is fixedly installed at the upper end of the other side of the pressure plate. symmetrically arranged insertion slots are provided on both sides of the cavity, and the insertion slots correspond to the positions of the connector plates.

[0004] The aforementioned patent requires workers to place the nut in the nut sleeve and control the nut sleeve to rotate and descend, connecting the nut to the output shaft of the pulley when installing the pulley in the generator. However, when the nut is placed manually in the nut sleeve, it may not be fully aligned at the beginning (e.g., it may be skewed or not fully inserted into the nut groove). This will cause eccentric rotation during high-speed tightening, resulting in periodic vibration, uneven stress on the nut and bolt, excessive pressure on some threads, causing thread damage, and long-term eccentric stress will cause bolt deformation, which is not conducive to the subsequent installation and disassembly of the pulley. Summary of the Invention

A second motor 4430, which drives the rotating rod 4429, is fixedly connected to the upper side of the mounting bracket 4427. Before tightening the nut, the worker first places the nut in the placement groove 4421. The structure of the placement groove 4421 is selected according to the shape of the nut. The placement groove 4421 initially limits the nut. Then, the second motor 4430 is controlled, which drives the rotating rod 4429 to rotate. The rotating rod 4429 drives the small gear 4428 to rotate. 8 drives the large gear 4426 to rotate, the large gear 4426 drives the rotating tube 41 to rotate, the rotating tube 41 drives the turntable 42 to rotate, the turntable 42 drives the branch plate 441 to rotate, the nut on the placement plate 4420 of the branch plate 441 rotates, and at the same time the branch plate 441 drives the abutment rod 449 to rotate. When the abutment rod 449 contacts the ramp 4410, it continues to rotate, causing the abutment rod 449 to drive the lifting block 448 to rise. The lifting block 448 drives the inclined plate 446 to rotate, the inclined plate 446 drives the slide plate 443 to move towards the nut sleeve 11, the slide plate 443 drives the moving plate 444 to move, the moving plate 444 drives the side plate 4416 to move, and the side plate 4416 drives the nut on the placement plate 4420 to move, so that the nut is aligned with the nut sleeve 11, which facilitates the nut to be installed in the correct orientation.

[0033] The lower end of the rotating rod 4429 passes through the lower side of the fixed frame 2 and is fixedly connected to the control panel 4431. The lower side of the control panel 4431 is fixedly connected to the slide rod 4432. A reciprocating frame 4433 is provided on the outer side of the slide rod 4432.

The inner side of the air box 4435 is provided to the piston plate 4438. The piston plate 4438 is fixedly connected to the reciprocating plate 4434. The front side of the air box 4435 is fixedly connected to the air inlet pipe 4436. A delivery pipe 4437 is fixedly connected between the air box 4435 and the rotating pipe 41. The upper side of the turntable 42 is fixedly connected to the top pipe 4. 3. An air box 4422 is fixedly connected to the outer side of the side plate 4416. A piston plate 4423 is installed inside the air box 4422. A control rod 4425 is fixedly connected to the upper side of the piston plate 4423. The upper end of the control rod 4425 passes through the upper side of the air box 4422 and is fixedly connected to the guide block 4418. A branch pipe 4415 is fixedly connected between the top pipe 43 and the air box 4422. A spring 4424 is fixedly connected between the outer side of the piston plate 4423 and the inner wall of the air box 4422. An exhaust pipe is fixedly connected to the outer side of the air box 4422. Solenoid valves are installed on the outer sides of both the exhaust pipe and the branch pipe 4415. An intake pipe 4436 and a delivery pipe 4437 are connected. One-way valves are installed on the outer sides of the plate. An infrared sensor is installed on the lower side of the placement plate 4420. The infrared sensor illuminates the working plate 1 with infrared light. When the illuminated position is directly below the nut sleeve 11, it indicates that the nut has moved to the position to be raised. At the same time, the rotating rod 4429 drives the control plate 4431 to rotate. The control plate 4431 drives the sliding rod 4432 to rotate. The sliding rod 4432 drives the reciprocating frame 4433 to move left and right repeatedly. The reciprocating frame 4433 drives the reciprocating plate 4434 to move. The reciprocating plate 4434 drives the piston plate 4438 to move left and right repeatedly. When the piston plate 4438 moves to the left, the one-way valve on the intake pipe 4436 allows external gas to enter the air box 4. In section 435, when piston plate 4438 moves to the right, gas is introduced into rotary pipe 41 through the one-way valve on delivery pipe 4437. Since rotary pipe 41 is connected to top pipe 43, the solenoid valve on branch pipe 4415 is controlled to allow gas to enter gas box 4422. The gas pushes piston plate 4423 to rise, piston plate 4423 drives control rod 4425 to rise, control rod 4425 drives guide block 4418 to rise, guide block 4418 drives connecting block 4419 to rise, connecting block 4419 drives placement plate 4420 to rise, placement plate 4420 drives nut to rise, so that nut moves into nut sleeve 11, completing the installation of nut and preventing nut installation misalignment.

[0034] Example 2

[0035] Based on Example 1, such as Figure 3-Figure 5 As shown, the stabilizing component 45 includes a fixed cylinder 451, which is fixedly connected to the upper side of the branch plate 441. A lifting rod 455 is fixedly connected to the upper side of the lifting block 448. The upper end of the lifting rod 455 passes through the upper side of the branch plate 441 and is fixedly connected to a piston disc 452. An airbag 454 is fixedly connected to the inner side of the placement groove 4421. A fixing tube 453 is fixedly connected between the airbag 454 and the fixed cylinder 451. When the nut is installed, the lifting block 448... The lifting rod 455 is raised, which in turn raises the piston disc 452. The piston disc 452 pushes the gas out of the fixed cylinder 451 and fills the airbag 454 with gas through the fixed pipe 453, causing the airbag 454 to expand and making the nut of the airbag 454 more secure. After installation, the gas in the second air box 4435 is discharged through the solenoid valve on the exhaust pipe of the second air box 4435. Under the action of the second spring 4424, the placement plate 4420 is lowered and reset. Then, the turntable 42 is controlled to rotate, so that the placement plate 4420 moves horizontally and resets.

[0036] Working principle: In use, the operator first places the nut in the placement slot 4421, then controls the motor 4430 to drive the rotating rod 4429 to rotate. Under the action of the small gear 4428 and the large gear 4426, the turntable 42 is controlled to rotate. Under the action of the branch plate 441 and the placement plate 4420, the nut is controlled to rotate. Through the abutment rod 449, the ramp 4410, the inclined plate 446, and the moving plate 444, the nut is easily moved to directly below the nut sleeve 11. At the same time, the rotating rod 4429... The control panel 4431 rotates, and under the action of the slide rod 4432, reciprocating frame 4433, reciprocating plate 4434, piston plate 4438, air box 4435, air inlet pipe 4436, and delivery pipe 4437, gas enters the jacking pipe 43. Through the branch pipe 4415, air box 4422, piston plate 4423, control rod 4425, guide block 4418, and connecting block 4419, the nut on the placement plate 4420 is raised, aligning with the nut sleeve 1. In step 1, simultaneously, the lifting rod 455 drives the piston disc 452 to rise. Under the action of the fixed cylinder 451 and the fixed tube 453, the airbag 454 inflates, facilitating the airbag 454 to limit the nut and increase the stability of the nut installation. The solenoid valve on the exhaust pipe of the air box 4422 is controlled to discharge the gas from the air box 4422, causing the placement plate 4420 to descend. Then, the turntable 42 is continuously controlled to rotate, causing the stop rod 449 to separate from the ramp 4410. Under the action of the spring 4411, the placement plate 4420 descends. 420 is reset to facilitate the installation of another nut. Then, the generator is placed on the working plate 1. Then, the electric push rod 13 is controlled to move the clamping plate 14, so that the clamping plate 14 limits the generator. Then, the electric push rod 8 is controlled to lower the mounting plate 9. The mounting plate 9 lowers the nut sleeve 11 on the control box 10, so that the nut on the nut sleeve 11 is lowered. At the same time, the motor 15 is controlled to drive the nut sleeve 11 on the conveyor shaft to rotate, so that the nut on the nut sleeve 11 limits the pulley.
