The dust collection mechanism is set above the grinding mechanism to collect the dust generated during grinding, thus solving the technical problem that a large amount of dust in existing grinding machines causes damage to operators and grinding machine parts during operation.

[0038] Working principle:

[0039] Before use, the grinding box 2 is positioned above the workbench 1. Open the protective door 414 at the front of the grinding box 2, and place the tricycle spindle to be ground into the grinding box 2. One end of the tricycle spindle is inserted into the limiting groove 408 on the surface of the fixed mounting turntable 402, and the other end is inserted into the limiting groove 408 on the surface of the movable mounting turntable 406. The mounting cylinder 407 on one side of the grinding box 2 pushes the movable mounting plate 405 to slide along the surface of the mounting groove 404, causing the movable mounting turntable 406 on the surface of the movable mounting plate 405 to move along the tricycle spindle. The other end is fixedly clamped. The tilting motor 403 on the other side of the grinding box 2 drives the fixed mounting turntable 402 on the surface of the fixed mounting plate 401 to rotate, so that the tricycle main shaft rotates along the axis, which is convenient for grinding. The adjustment motor 3 on the surface of the grinding box 2 drives the adjustment screw 301 inside the grinding box 2 to rotate. One end of each of the two adjustment screws is provided with an adjustment bevel gear 303. Both ends of the connecting shaft 306 are provided with connecting bevel gears 305, which are respectively connected to the surface of the two adjustment bevel gears 303 for transmission, so that the two adjustment screws 301 rotate synchronously. The adjusting sliders 302 on the surfaces of the two adjusting screws 301 move synchronously, ensuring the smooth movement of the mounting box 307 above the two adjusting sliders 302. A dust cover 304 is provided on the outside of the adjusting screws 301 to protect their surfaces and prevent damage from grinding dust. A grinding motor 309 on the surface of the mounting box 307 drives the grinding screw 308 inside the mounting box 307 to rotate, causing the grinding slider 310 on the surface of the grinding screw 308 to move along the length of the mounting box 307 for grinding. The grinding strip 311 on the surface of the slider 310 performs a full grinding of the surface of the tricycle's main shaft. The explosion-proof fan 410 above the grinding box 2 discharges the dust generated inside the grinding box 2 upward through the dust suction hopper 409 on the top of the grinding box 2. External air enters the grinding box 2 through the ventilation slots 415 on both sides of the grinding box 2, which in turn drives the dust inside the grinding box 2 into the guide pipe 411 through the explosion-proof fan 410. A dust collection bag 412 is installed at the end of the guide pipe 411 for collection. The bottom of the dust collection bag 412 is supported by the shelf 413 on the surface of the grinding box 2.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
