[0002] Gears are the main components for mechanical transmission on many machines. During the production and processing of gears, in order to ensure the flatness of the gears or the smoothness of the tooth surfaces, a grinding device is required to grind the gears. The existing grinding devices for gear processing mainly complete the grinding work of gears by the friction between the gears and the grinding wheels. However, because the rotational speed of the grinding wheels is relatively fast during the grinding process, the debris generated during the grinding process will fly everywhere along with the rotation of the grinding wheels. If the flying iron filings are not processed in time, they will get stuck on the gears or the wheels, causing scratches or damage to them. Therefore, it is necessary to stop the machine regularly for cleaning work. However, because the iron filings fly everywhere and some will get stuck inside, it is very inconvenient to clean. Therefore, the existing grinding devices for gear processing have the problem of inconvenient cleaning. Content of the Utility Model

[0016] Embodiment. A gear grinding device convenient for cleaning, the structure is as Figures 1 to 3 shown, including a base 1, a grinding wheel 2, a grinding motor 3 and a positioning seat 4 for placing a gear. A chip collection groove 5 is provided at a position corresponding to between the grinding wheel 2 and the positioning seat 4 on the base 1. A left baffle 6 and a right baffle 7 located on the top surface of the base 1 are respectively arranged on both sides of the chip collection groove 5. Rotating parts are arranged at the bottom ends of the left baffle 6 and the right baffle 7, and a driving motor is installed at the end of one of the rotating parts. A chip collection plate 8 is installed between the two rotating parts. The chip collection plate 8 is arranged directly above the chip collection groove 5, and an electromagnet 9 is arranged inside the chip collection plate 8. An upper baffle 10 is installed between the top ends of the left baffle 6 and the right baffle 7, and a power supply 11 for supplying power to the electromagnet 9 is arranged on the top surface of the upper baffle 10.
[0017] On the side of the left baffle 6 facing the chip collecting plate 8, a left limit stop 12 and a positive electrode connector 13 are provided. The left limit stop 12 and the positive electrode connector 13 are arranged on the moving path of the chip collecting plate 8. The positive electrode connector 13 is electrically connected to the power supply 11 and is arranged directly below the chip collecting plate 8. The left limit stop 12 is arranged directly above the chip collecting plate 8. On the side of the right baffle 7 facing the chip collecting plate 8, a right limit stop 14 and a negative electrode connector 15 are provided. The right limit stop 14 and the negative electrode connector 15 are arranged on the moving path of the chip collecting plate 8. The negative electrode connector 15 is electrically connected to the power supply 11 and is arranged directly below the chip collecting plate 8. The right limit stop 14 is arranged directly above the chip collecting plate 8. At the positions corresponding to the positive electrode connector 13 and the negative electrode connector 15 on the bottom surface of the chip collecting plate 8, connection grooves are provided. On the inner bottom surface of each connection groove, an electrode piece electrically connected to the electromagnet 9 is provided. The positive electrode connector 13 and the negative electrode connector 15 are electrically connected to the electromagnet 9 through the electrode pieces. On both side walls of the chip collecting plate 8, grooves 16 are provided. A slide rail 17 is arranged in each groove 16. A slider 18 is slidably mounted on each slide rail 17. A scraping plate 19 located directly above the chip collecting plate 8 is arranged between the two sliders 18. The bottom surface of the scraping plate 19 is in contact with the top surface of the chip collecting plate 8. An air duct 20 is provided on the bottom surface of the upper baffle 10. A plurality of evenly distributed air nozzles 21 are provided on the air duct 20. Each air nozzle 21 faces the chip collecting plate 8. A drawer is slidably mounted in the chip collecting groove 5.
[0018] Working principle: When specifically carrying out the grinding work, first connect the entire device to the external safe mains power supply; then control the driving motor to start. After the driving motor starts, it will drive the rotating shaft to rotate. After the rotating shaft rotates, it will drive the chip collecting plate to rotate clockwise, so that the chip collecting plate becomes horizontal, and the surface of the chip collecting plate 8 with the connecting groove is set facing the chip collecting groove 5. At this time, the positive electrode connector 13 and the negative electrode connector 15 will be correspondingly stuck in the connecting grooves on the chip collecting plate 8 and contact the motor piece, so that the power supply 11 and the electromagnet 9 are in a connected state. After the electromagnet 9 is energized, a magnetic field will be formed around it, so that the iron chips generated during the subsequent grinding process will be adsorbed on the chip collecting plate by the magnetic field; then place the gear to be ground on the positioning seat 4, and then control the grinding motor 3 to start. After the grinding motor 3 starts, it will drive the grinding wheel 2 to rotate, and the grinding wheel 2 can be used to grind the surface of the gear; during the grinding process, control the external blower to input air flow into the air duct 20, and the air flow flowing into the air duct 20 will blow towards the gear and the grinding wheel 2 through the air nozzle 21. While cooling the gear and the grinding wheel 2, it can also guide the falling of the iron chips to a certain extent, so that the iron chips can move towards the chip collecting plate 8 as much as possible. Because the electromagnet 9 in the chip collecting plate 8 is in an energized state, the iron chips will be stably adsorbed on the surface energy of the chip collecting plate 8 under the action of the magnetic field; at the same time, the left baffle 6, the right baffle 7 and the upper baffle 10 can also protect around the grinding wheel 2 to prevent the iron chips from splashing everywhere.
[0019] When it is necessary to clean the iron chips on the chip collecting plate 8, or when the iron chips adsorbed on the chip collecting plate 8 reach a certain thickness, it is necessary to first control the grinding motor 3 to stop, and then control the driving motor to start in the reverse direction, so that the driving motor drives the chip collecting plate 8 to rotate counterclockwise. At this time, as the chip collecting plate 8 rotates, the negative electrode connector 15 and the positive electrode connector 13 will separate from the connecting grooves on the chip collecting plate 8, so that the electromagnet 9 is disconnected from the power supply 11. The magnetic field generated around the electromagnet 9 will gradually disappear after being powered off. As the chip collecting plate 8 rotates, the chip collecting plate 8 slowly becomes vertical. Under the combined action of the disappearance of the magnetic field and the vertical state of the chip collecting plate 8, the iron chips previously adsorbed on the chip collecting plate 8 will slowly fall into the lower chip collecting groove 5 for centralized collection; if the falling speed of the iron chips on the chip collecting plate 8 is slow, the operator can also slide the scraping plate 19 in the direction of the slide rail 17, so that the scraping plate 19 can scrape on the surface of the chip collecting plate 8, so as to accelerate the falling of the iron chips on the chip collecting plate; finally, the iron chips collected in the chip collecting groove 5 can be cleaned by pulling out the drawer in the chip collecting groove 5, and the whole cleaning work is convenient.
