[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a burr-removing mechanism for automotive connecting rods, including a grinding box 1, with a movable wheel 2 fixedly connected to the bottom outer wall of the grinding box 1, characterized in that: a dust filter baffle 3 is fixedly connected to the inner wall of the grinding box 1, and a movable structure 4 is fixedly connected to the top outer wall of the dust filter baffle 3, with a clamping structure 5 provided on the movable structure 4, and an automotive connecting rod 6 clamped and fixed on the clamping structure 5;

[0027] An electric telescopic push rod 11 is fixedly connected to the top outer wall of the grinding box 1. A mounting bracket 12 is fixedly connected to the lower end of the electric telescopic push rod 11. A motor 13 is fixedly connected to the inner wall of the mounting bracket 12. A grinding head 14 is fixedly connected to the output end of the motor 13. A primary dust collection device and a secondary dust collection device are provided in the grinding box 1.

[0028] The primary dust collection device includes a dust collection box 7, which is fixedly installed inside the grinding box 1. The dust collection box 7 is located below the dust filter baffle 3. A dust conveying pipe 10 is inserted through the inner wall of the dust collection box 7. A vacuum cleaner 8 is fixedly connected to the outer wall of the grinding box 1. A fan 9 is fixedly connected to the top of the vacuum cleaner 8. The end of the dust conveying pipe 10 away from the dust collection box 7 is fixedly connected to the fan 9.

[0029] The primary dust collection device also includes a dust collection protective cover 15. The dust collection protective cover 15 is fixedly connected to the four outer walls of the mounting frame 12. Dust collection pipes 16 are inserted through the four inner walls of the dust collection protective cover 15. The four dust collection pipes 16 are interconnected. A connecting pipe 17 is fixedly connected to the outer wall of the dust collection pipe 16. The other end of the connecting pipe 17 is connected to the dust conveying pipe 10.

[0030] In this embodiment, the car connecting rod 6 is fixed to the movable structure 4 by the clamping structure 5. The movable structure 4 is located above the dust filter baffle 3. The electric telescopic push rod 11 adjusts the height of the mounting bracket 12 and the grinding head 14 according to the set program so that they contact the car connecting rod 6. The motor 13 is started, and the motor 13 drives the grinding head 14 to rotate at high speed. At the same time, the grinding operation on the burrs of the car connecting rod 6 begins. The position of the car connecting rod 6 can be adjusted by the movable structure 4 to perform all-round grinding.

[0031] During the polishing process, the vacuum cleaner 8 and the fan 9 work together. The fan 9 generates suction, which draws out the air from the dust collection box 7 through the dust conveying pipe 10, creating a negative pressure inside the dust collection box 7. The dust and debris generated during polishing are then sucked in through the dust conveying pipe 10. The dust suction pipes 16 on the four sides of the dust suction protective cover 15 suck in the dust and debris generated during polishing, and then transport them to the dust collection box 7 through the connecting pipe 17 and the dust conveying pipe 10.

[0032] The movable structure 4 consists of a slide rail, a lead screw, a drive mechanism, and a movable block. The lead screw is rotatably connected inside the slide rail, and the movable block is threadedly connected to the outer wall of the lead screw. The drive mechanism provides power for the rotation of the lead screw, and a clamping structure 5 is provided on the top of the movable block.

[0033] In this embodiment, the drive structure is activated to rotate the lead screw, which in turn drives the moving block to move left and right. The moving block then drives the clamping structure 5 to move left and right, causing the car connecting rod 6 on the clamping structure 5 to change position accordingly.

[0034] The inner wall of the grinding box 1 is fixedly connected to a dust filter baffle 18. The inner wall of the grinding box 1 and the outer side of the dust filter baffle 18 are fixedly connected to a dust collection box 19. The bottom of the dust collection box 19 is fixedly connected to a dust conveying pipe 20. The rear side wall of the grinding box 1 is fixedly connected to a vacuum cleaner 21. The top outer wall of the vacuum cleaner 21 is fixedly connected to a fan 22. The end of the dust conveying pipe 20 away from the dust collection box 19 is connected to the fan 22.

[0035] In this embodiment, some dust and debris that are not completely collected by the dust collection shield 15 will float in the grinding box 1. Under the action of the fan 22 and the vacuum cleaner 21, the air is drawn into the dust collection box 19 through the dust conveying pipe 20 after passing through the dust filter baffle 218.

[0036] Among them, dust collection box 17 is wider at the top and narrower at the bottom, and its bottom is sloping. Dust collection box 219 is wider on the left and narrower on the right, and its right side is sloping.

[0037] In this embodiment, dust collection box 7 is inclined with a wider top and a narrower bottom, and dust collection box 19 is inclined with a wider left and a narrower right, so that dust and debris can be easily collected at the bottom under the action of gravity and airflow, making it easy to clean.

[0038] Both the dust filter baffle 3 and the dust filter baffle 18 have several mesh holes, which are evenly distributed in an array on the dust filter baffle 3 and the dust filter baffle 18.

[0039] Working principle: In use, the car connecting rod 6 is fixed to the movable structure 4 via the clamping structure 5. The movable structure 4 is located above the dust filter baffle 3. The electric telescopic push rod 11 adjusts the height of the mounting bracket 12 and the grinding head 14 according to the set program, so that they contact the car connecting rod 6. The motor 13 is started, and the motor 13 drives the grinding head 14 to rotate at high speed, and at the same time, the burrs on the car connecting rod 6 are ground. The position of the car connecting rod 6 can be adjusted by the movable structure 4 to perform all-round grinding. During the grinding process, the vacuum cleaner 8 and the fan 9 work together. The fan 9 generates suction, and the dust collection box 7 is drawn through the dust conveying pipe 10. The air inside is extracted, creating a negative pressure inside the dust collection box 7. Dust and debris generated during grinding are sucked in through the dust conveying pipe 10. The dust and debris generated during grinding are sucked in by the dust suction pipes 16 on all four sides of the dust suction shield 15 and transported to the dust collection box 7 through the connecting pipe 17 and the dust conveying pipe 10. Some dust and debris that are not completely collected by the dust suction shield 15 will float in the grinding box 1. Under the action of the fan 22 and the vacuum cleaner 21, the air is sucked into the dust collection box 19 through the dust conveying pipe 20 after passing through the dust filter baffle 218, further purifying the air environment inside the grinding box 1 and reducing the impact of dust on the internal components of the equipment and the pollution to the external environment.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
