[0014] Preferably, the movable block is provided with sliding grooves on both upper and lower sides, and the driving block is fixedly connected with limiting rods on both upper and lower sides, and the limiting rods are slidably connected to the inside of the sliding grooves.

[0015] Working principle: When grinding, first start the motor. When the output end of the motor rotates, it can drive the grinding belt to rotate, so that the manipulator can be used to clamp the metal parts to the grinding belt for grinding. Before using the grinding belt for grinding, it is necessary to adjust the tightness of the grinding belt. When adjusting the tightness, first start the hydraulic cylinder. When the output end of the hydraulic cylinder outputs, it drives the triangular block to rotate. When driving the triangular block to rotate, it can drive the connecting rod to move in the slide groove, thereby driving the mounting shell to move, and then the tightness of the grinding belt can be adjusted. When the grinding belt is tightened, the pressure on the grinding belt will be transmitted to the support block, and the support block will transmit the pressure to the movable block, and the elastic force on the adjustment spring can be used to adjust the tightness of the grinding belt. The cam is then rotated to move the drive plate in a counterclockwise direction, and then the drive rod is driven to move outwards, and the drive block is driven to move outwards, and after the drive rod moves outwards, the drive block is driven to move outwards, and after the drive block moves outwards, the drive block is driven to move outwards, and since the drive block is in contact with the grinding belt, the grinding belt can be used to block the drive block, and thus the drive block can be used to squeeze the adjusting spring, thereby increasing the elasticity of the adjusting spring, and then increasing the rigidity between the support block and the grinding belt, and vice versa. At the same time, when the output end of the motor rotates, it can drive the sector gear to rotate, and after the sector gear rotates, it can drive the gear ring plate to move back and forth, and after the gear ring plate moves back and forth, it can drive the push-pull rod to move back and forth, and when the push-pull rod moves back and forth, it can drive the piston to move back and forth. When the piston moves in the direction of the sector gear, the one-way valve two is closed and the one-way valve one is opened, so that the air inside the dust collecting bucket can be sucked away. When the piston moves to one side of the dust collecting bucket, the one-way valve two is opened and the one-way valve one is closed, so that the air in the air cylinder can be discharged through the one-way valve two. When an air pressure difference is generated inside the dust collecting bucket, the suction force can be transmitted to the hose, so that the suction force can be expanded by using the dust collecting head. At this time, the dust generated during grinding can be sucked away by the dust collecting head, thereby preventing dust from polluting the working space. When the pressure difference in the dust bucket is too large, the top cap will be sucked to move downward, thereby compressing the reset spring. When the air vent is aligned with the air inlet, the inside of the dust bucket can be connected to the outside world, so that the outside air can be sucked into the inside of the dust bucket, thereby balancing the air pressure of the dust bucket and the outside world, and then protecting the dust bucket. When the internal pressure of the dust bucket decreases, the top cap is reset under the elastic action of the reset spring, so that the air inlet is blocked by the top cap, and then the internal pressure of the dust bucket can be prevented from decreasing. When the dust inside the dust bin needs to be cleaned, the clamping sleeve is rotated outwardly so that the clamping sleeve can pull the locking column out of the outside of the locking column. At this time, the clamping sleeve is loosened, and the movable sleeve is driven to move in the direction of the mounting column under the action of the tension spring, so that the rotating door can be loosened, and then the rotating door can be opened, so that the dust inside the dust bin can be cleaned conveniently. When closing the rotating door, the rotating door is first closed, and then the clamping sleeve is pulled outward, and the movable sleeve is driven by the movement of the clamping sleeve, so that the tension spring can be stretched. At this time, the clamping sleeve is buckled on the locking column, so the tension spring can be used to pull the rotating door to prevent the rotating door from opening, and then the sealing of the dust bin can be maintained.

[0016] The present invention provides a metal parts grinding device for automobile manufacturing, which has the following beneficial effects: 1. The present invention adjusts the elasticity of the spring so that the support block contacts the grinding belt flexibly, so that when the grinding belt is tightened, it will have a certain elasticity during grinding, so that the grinding belt will not break during the grinding process, thereby avoiding economic losses and preventing workers from being injured when the grinding belt breaks, thereby preventing accidents.

[0017] 2. The present invention uses a vacuum suction mechanism to suck the dust generated during grinding into the interior of the dust collecting bucket, thereby preventing the dust from floating in the working space, thereby keeping the working space clean and tidy, and further ensuring the health of the staff.

The outside of the connecting rod 504 is fixedly connected to a mounting shell 505. The mounting shell 505 can provide an installation space. The top of the internal top of the mounting shell 505 is rotatably connected to a driving disk 506. The inside of the driving disk 506 is provided with an inclined groove 507. The top of the driving disk 506 is fixedly connected to The movable rod 509 can drive the driving disk 506 to rotate. The top of the mounting shell 505 is rotatably connected with a threaded rod 510. Twisting the threaded rod 510 can drive the driving disk 506 to rotate. An arc groove 511 is provided inside the top of the mounting shell 505. A fixed sleeve 512 is fixedly connected to the middle of the mounting shell 505. The fixed sleeve 512 can play a limiting role.

The adjusting spring 514 can provide elastic force. A driving block 515 is slidably connected to the inside of the movable block 513. The driving block 515 can provide an extrusion effect. The adjusting spring 514 is fixedly connected to the driving block 515 on the side close to the connecting rod 504. Inside the block 515, the top of the driving block 515 is fixedly connected with a driving rod 508, and the driving rod 508 provides a driving function. The top of the driving rod 508 is arranged inside the inclined groove 507. The side of the movable block 513 away from the driving block 515 is fixedly connected with a support block 518. The top of the fixed plate 501 is rotatably connected with a hydraulic cylinder 520. The top of the fixed plate 501 is rotatably connected with a driving triangular block 519. One end of the driving triangular block 519 is rotatably connected to the outside of the connecting rod 504, and the other end of the driving triangular block 519 is rotatably connected to the output end of the hydraulic cylinder 520. The outside of the moving rod 509 is slidably connected to the inside of the arc groove 511, and the side of the threaded rod 510 close to the arc groove 511 is rotatably connected to the top of the moving rod 509.

One end of the tension spring 803 is fixedly connected to the mounting column 801 near the clamping sleeve. The other end of the tension spring 803 is fixedly connected to one side of the movable sleeve 804 near the mounting post 801, and the clamping sleeve 806 is rotated outward, so that the clamping sleeve 806 can pull the locking post 807 out of the locking post 807. At this time, the clamping sleeve 806 is loosened, and the movable sleeve 804 is driven to move toward the mounting post 801 under the action of the tension spring 803, so that the rotating door 808 can be loosened, and then the rotating door 808 can be opened, so that It is convenient to clean the dust inside the dust bin 613. When closing the rotating door 808, first close the rotating door 808, and then pull the clamping sleeve 806 outward, and use the movement of the clamping sleeve 806 to drive the movable sleeve 804, so that the tension spring 803 can be stretched.
