Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts grinding equipment, in particular to a grinding device for automobile parts. Background Art

[0002] After automobile parts are manufactured and produced, in order to improve the surface quality of the parts, workers are usually required to hold the parts and manually grind them on a grinding machine to remove burrs on the parts. Since a certain amount of metal scraps will be generated during the grinding process, in order to avoid the metal scraps from polluting the working environment and endangering the health of the workers, a vacuum cleaner is generally installed under the existing grinding machine to suck in the flying metal scraps and collect them into the dust removal box. Although the vacuum cleaner can effectively ensure the hygiene of the working environment and the health of the workers, the metal scraps passing through the vacuum cleaner fan will continuously wear the fan blades, which not only reduces the normal service life of the vacuum cleaner, but also requires the vacuum cleaner to be disassembled regularly for cleaning, which leads to a high dust removal cost for the grinding machine. Utility Model Content

[0003] The utility model aims to provide a grinding device for automobile parts, which has the effects of ensuring the service life of dust removal equipment and reducing the dust removal cost of the grinding device.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions: a grinding device for automobile parts, comprising a chassis, a double-headed motor fixedly mounted on the top of the chassis, a grinding wheel fixedly mounted on the two output ends of the two double-headed motors, a waste chip collection box fixed on the top of the chassis and located below the grinding wheel, and a dust removal mechanism arranged inside the chassis and connected to the bottom of the waste chip collection box, the dust removal mechanism comprising a dust removal cylinder fixed in the chassis, a rotating tube vertically rotating inside the dust removal cylinder, a fan-shaped column fixed on both sides of the rotating tube, a rotating assembly driving the rotating tube to rotate, a fan fixedly mounted on the bottom of the chassis and a pair of waste chip storage boxes, a pair of dust removal boxes at one end and a pair of dust removal boxes at the other end. A waste chip conveying pipe 1 is connected to the two waste chip collection boxes, and a pair of waste chip conveying pipes 2 are respectively connected to the two waste chip storage boxes at one end. The lower end of the rotating pipe rotates to pass through the bottom of the dust removal cylinder and is connected to the air inlet of the fan through a rotating joint. The fan-shaped column is in contact with the inner wall of the dust removal cylinder away from the rotating tube. The other end of the two waste chip conveying pipes 1 is connected to the top of the dust removal cylinder and is located between the gaps at the tops of the two fan-shaped columns of the rotating tube. The other end of the two waste chip conveying pipes 2 is connected to the bottom of the dust removal cylinder and is located at the bottom of the two fan-shaped columns of the rotating tube. The rotating tube is provided with a plurality of small ventilation holes in the gap between the two fan-shaped columns.

[0005] By adopting the above technical scheme, when the grinding wheels at the two output ends of the double-headed motor are to grind the workpiece, the rotating assembly is first used to control the rotation of the rotating tube, so that the fan-shaped columns on both sides of the rotating tube respectively cover the openings of the bottom of the dust removal cylinder connected to the waste chip conveying tube 2, and at the same time, the opening of the top of the dust removal cylinder connected to the waste chip conveying tube 1 is directly opposite to the gap between the two fan-shaped columns. Then the fan is started to blow air outside the rotating cylinder. Since the rotating tube has small ventilation holes in the gap between the two fan-shaped columns, and the lower end of the rotating tube is connected to the fan inlet through a rotating joint, the waste chips generated by the grinding wheel when grinding the workpiece will be sucked into the dust removal cylinder through the waste chip collection box and the waste chip conveying tube 1 in sequence under the action of the fan suction. The dust collecting cylinder is then emptied of the dust and is then blown away by the fan-shaped cylinders which are connected to the vents of the rotating tube.

[0006] The utility model is further configured as follows: the rotating assembly includes a rotating shaft 1 that rotates on the top of the dust removal cylinder, a worm gear fixedly mounted on the rotating shaft 1, a rotating shaft 2 that rotates in the chassis and is perpendicular to the rotating shaft 1, and a worm fixedly mounted on the rotating shaft 2 and meshing with the transmission worm gear; the upper end of the rotating tube rotates to pass through the top of the dust removal cylinder and is fixedly connected to the rotating shaft 1; one end of the rotating shaft 2 rotates to pass through the chassis and is fixedly connected to a handle.

[0007] By adopting the above technical solution, when it is necessary to rotate the rotating tube in the dust removal cylinder, first manually turn the handle outside the chassis, then the rotating shaft two connected to the handle will drive the worm inside the chassis to engage the worm gear, and finally the worm gear drives the rotating shaft one to rotate, so that the rotating tube connected to the rotating shaft one rotates together.

[0008] The utility model is further configured as follows: protective covers for protecting the grinding wheel are fixedly provided at both ends of the housing of the double-headed motor, and the protective covers are located inside the waste chip collection box, and a gap is left between the protective cover and the front side of the waste chip collection box for the grinding wheel to grind parts.

[0009] By adopting the above technical solution, when the grinding wheel is grinding a workpiece, the protective cover can not only prevent workers from accidentally touching the high-speed rotating grinding wheel to ensure the workers' safety, but also help the waste chip collection box collect metal waste to ensure the cleanliness of the working environment.

[0010] The utility model is further configured as follows: a discharge port is provided on one side of the waste storage box, and a drawer is slidably installed.

[0011] By adopting the above technical solution, it is convenient for workers to take out the metal scraps stored in the scrap storage box.

[0012] The utility model is further configured as follows: four universal running wheels are installed at the bottom of the chassis and are respectively close to the four corners of the chassis.

[0013] By adopting the above technical solution, it is convenient for workers to transfer and use the grinding device at any time.

[0014] The beneficial effects of the utility model are as follows: through the dust removal structure inside the chassis, not only can the metal waste generated when the grinding wheel grinds the workpiece effectively be absorbed to ensure the hygiene of the working environment and the health of the staff, but the connection structure between the dust removal cylinder, the rotating cylinder and the fan can also prevent the metal waste from directly contacting the fan blades inside the fan, thereby increasing the service life of the fan. At the same time, the fan-shaped columns on both sides of the rotating tube, and the pipes connected to the dust removal cylinder, etc., can also cooperate with the fan to work in reverse to achieve the effect of simply and quickly cleaning the ventilation holes on the rotating tube and the inside of the dust removal cylinder, thereby reducing the number of times the dust removal equipment is manually disassembled for cleaning and greatly reducing the dust removal cost of the grinding device.
