Technical Field

[0001] The utility model relates to the technical field of grinding wheels, in particular to a scraping device for producing grinding wheels. Background Art

[0002] Grinding wheel is also called bonded abrasive tool. Grinding wheel is a bonded abrasive tool with a certain strength. It is made of ordinary abrasives bonded into a certain shape (mostly round with a through hole in the center) by a bonding agent. It is generally composed of abrasives, bonding agents and pores. These three parts are often called the three elements of bonded abrasive tools.

[0003] As a main grinding tool, in the traditional production process, the grinding wheel is made by a multi-station semi-automatic grinding wheel forming machine, which uses manual auxiliary positioning of the grinding wheel and then scrapes the blank surface of the grinding wheel;

The inner arc surface of the insert cylinder 47 is slidably connected with the wheel cylinder 49. The lower end is provided with a chassis 48, the sealed scraper mechanism 4 also includes a scraper motor 42, the scraper motor 42 is arranged on the upper surface of the sealing cylinder 43, the output shaft of the scraper motor 42 is fixedly connected to the rotating shaft at the upper end of the arc scraper 44, the input end of the scraper motor 42 is electrically connected to the output end of the single-chip computer 7, the sealed scraper mechanism 4 also includes a vent 46, the vent 46 is evenly arranged on the outer arc surface of the sealing cylinder 43, the vent 46 is connected to the retention groove 45, the left end of the retention groove 45 on the left is connected to the external fan, and the right end of the vent The right end of the tube 46 is connected to an external dust suction mechanism. When the grinding wheel needs to be scraped, the grinding wheel is placed inside the wheel cylinder 49. At this time, the chassis 48 can be lifted by the handle 10, and then the chassis 48 is placed on the electric conveyor belt 6. At this time, the single-chip microcomputer 7 can be regulated to operate the scraping motor 42, and the output shaft of the scraping motor 42 rotates at a high speed, thereby driving the arc scraper 44 to rotate at a high speed. At this time, the first cylinder 3 of the external air pump can be regulated to operate, and the telescopic end of the first cylinder 3 extends, thereby driving the insert cylinder 47 moves downward until the wheel-setting cylinder 49 is completely inserted into the inserting cylinder 47. In this process, the arc scraper 44 scrapes the upper surface of the grinding wheel in the wheel-setting cylinder 49. Because the arc scraper 44 is curved, the dust generated when scraping the grinding wheel will hit the inner curved surface of the sealing cylinder 43 obliquely, and then fall into the retention groove 45.

When it moves to the middle of the electric conveyor belt 6, the two arc limit rods 51 tightly hold the outer arc surface of the wheel cylinder 49 to limit its position and prevent it from moving backward. After completing the operation, each electrical appliance is regulated to reset, and the electric conveyor belt 6 continues to transport the chassis 48 backward until the chassis 48 moves to the discharge plate 9. At this time, the grinding wheel can be manually taken, and then the above operations can be repeated to complete the scraping operation of the next grinding wheel.

[0029] The working principle of a scraper device for grinding wheel production provided by the utility model is as follows: when it is necessary to scrape the grinding wheel, the grinding wheel is placed inside the wheel barrel 49. At this time, the chassis 48 can be lifted by the handle 10, and then the chassis 48 is placed on the electric conveyor belt 6. At this time, the external air pump can be regulated, and the second cylinder 53 can be regulated to operate at the same time. The two second cylinders 53 are extended at the same time, and then the two arc limit rods 51 are moved to the specified position through the mounting plate 52.

At this time, the single-chip microcomputer 7 can be regulated, the scraper motor 42 can be operated, and the output shaft of the scraper motor 42 rotates at high speed, thereby driving the arc scraper. 44 rotates at high speed, at this time, the external air pump first cylinder 3 can be regulated to operate, the telescopic end of the first cylinder 3 extends, and then drives the insert cylinder 47 to move downward until the wheel cylinder 49 is completely inserted into the inside of the insert cylinder 47. In this process, the arc scraper 44 scrapes the upper surface of the grinding wheel in the wheel cylinder 49. Because the arc scraper 44 is curved, the dust generated when scraping the grinding wheel will hit the inner arc surface of the sealing cylinder 43 obliquely, and then fall into the inside of the retention groove 45. At this time, the external external fan and the external dust suction mechanism can be regulated to form an air circulation space with the retention groove 45 through the ventilation pipe 46 to discharge the dust inside the retention groove 45. After completing the operation, the various electrical appliances are reset, and the electric conveyor belt 6 continues to convey the chassis 48 backward until the chassis 48 moves to the discharge plate 9.
