Description

Technical Field

[0001] The invention belongs to the technical field of grinding machine processing, and in particular relates to a dust reduction device for a grinding machine. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders and polishing machines. The grinding process will produce a lot of iron filings and dust, which will affect the health of workers after inhalation. Therefore, grinders usually need to be equipped with corresponding dust reduction devices.

[0003] The prior art discloses some invention patents in the field of grinding machine processing technology, among which the invention patent with publication number CN115972098A discloses an automatic coolant supply device for a grinding machine, which relates to the field of grinding machine processing. Aiming at the problem that the existing grinder cannot realize automatic coolant supply when processing a workpiece, the following scheme is proposed, which includes a grinding machine body, a water tank is fixedly installed on the top of the grinding machine body through four support rods with the same structure, and a liquid collecting box is fixedly installed on one side of the bottom end of the water tank, a lower liquid port is provided between the liquid collecting box and the water tank, and a nozzle is installed on the side of the liquid collecting box close to the center line of the grinding machine body, a first mounting plate and a second mounting plate are slidably installed on the top of the grinding machine body, and a fixed The fixture for fixing the workpiece has a novel structure, and the device can automatically cool and dust the workpiece during the processing, protect the workpiece, and recycle the coolant to avoid waste of water resources. The technical solution still has some shortcomings in the process of application. The hood can effectively prevent the metal chips generated by grinding and the coolant acting on the grinding wheel from splashing everywhere, and has a good protective effect on the respiratory tract, vision and grinding bed of the staff. However, the appearance of the hood will weaken the staff's observation of the grinding process of the workpiece. At the same time, the metal chips generated in the grinding process are prone to sedimentation under the action of cooling water. The settled metal chips are located on the workpiece, and it is difficult to make the settled metal chips flow upward by suction alone, affecting the subsequent grinding accuracy.

[0048] Working principle, when using:

[0049] First, the workpiece to be polished is placed on the workbench 2, and then the built-in motor of the driving frame 402 is controlled to operate. The motor drives the grinding wheel 403 to rotate rapidly through the main shaft. Then, the main shaft box 3 is controlled to drive the slide 401 to drive the driving frame 402 to move downward. After the grinding wheel 403 comes into contact with the workpiece, the polishing operation is performed. In this process, the workpiece and the polishing wheel are driven to move relative to each other by controlling the workbench 2, so as to perform comprehensive polishing on the required processing parts of the workpiece.

[0050] A coolant spray pipe is installed on the dust cover 501 corresponding to the grinding wheel. When the grinding wheel 403 is grinding the workpiece, coolant is sprayed to the grinding wheel 403 through the coolant spray pipe to reduce friction heat and spark generation, and the dust collector 504 is controlled to work. The dust collector 504 applies suction force to the dust removal suction head 502 through the dust collection pipe 503, and the dust removal suction head 502 sucks metal chips and cooling water generated by grinding in the dust cover 501;

[0051] In the process of manipulating the workbench 2 to move the workpiece, the workbench 2 will drive the first driving wheel 6041 to roll on the top thereof, and the first driving wheel 6041 will drive the first wheel shaft to rotate. During the rotation of the first wheel shaft, the swing shaft 6043 will be driven to rotate, and the other end of the swing shaft 6043 will drive the first driving shaft 6044 and one end of the second driving shaft 6042 to perform circular motion synchronously. In this process, the swing shaft 6043 will generate a pulling force or a thrust force on the tail ends of the first driving shaft 6044 and the second driving shaft 6042. Under the action of the pulling force or the thrust force, the second cleaning rod 6054 will swing through the second rotating shaft 6052, and the second cleaning rod 6054 will move in a circular motion. The other end rotates around the end of the bridge rod 6055, and the other end of the bridge rod 6055 rotates around the first cleaning rod 6053, and pulls the first cleaning rod 6053 and the second cleaning rod 6054 to swing synchronously, thereby driving the cleaning brush 6056 to wipe the perspective lens 602, so that the perspective lens 602 maintains the perspective effect. The first lens cleaning member 605 and the second lens cleaning member 606 are combined, so that the perspective lens 602 can be fully cleaned. The dust cover 501 is provided to prevent metal chips generated by grinding and cooling water acting on the grinding wheel 403 from splashing everywhere, thereby ensuring the cleanliness of the workbench 2;

[0052] In the process of operating the workbench 2 to drive the workpiece to move, the workbench 2 will also drive the second driving wheel 8012 to roll on its top. In the process of rolling, the multiple second driving wheels 8012 drive the second wheel axle 8011, and the second wheel axle 8011 drives the U-shaped shaft 8013 to rotate. In the process of the second wheel axle 8011 driving the U-shaped shaft 8013 to rotate, the end of the piston shaft is driven through the adapter sleeve 8014, and in this process, the adapter sleeve 8014 rotates on the U-shaped shaft 8013, so that the slider 8015 can be pushed or pulled to slide in the slide groove in a circular manner, and the tooth panel 802 is driven to move on the tooth surface through the slider 8015. The gear 803 rotates and drives the pitch axis 804 to rotate, so that the nozzle 9 can be driven to pitch. The air pipe 10 is externally connected to a fan, and the fan introduces the pressurized air into the nozzle 9 through the air pipe 10. In the process of the nozzle 9 doing the pitching movement, the metal chips and cooling water generated by the grinding wheel 403 can float upward.
