Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of blade cutting, specifically an automatic burr cutting device for wind turbine blades. STATE OF THE ART

[0002] Currently, the Chinese wind turbine blade market has formed a diversified investment landscape, encompassing foreign-funded enterprises, private companies, research institutes, and listed companies. Foreign-funded enterprises mainly include GE, LM, GAMESA, and VESTAS, while domestic companies are represented by Times New Material, Sinoma Science & Technology, AVIC Huiteng, and Zhongfu Lianzhong. During the processing of wind turbine blades, it is necessary to trim burrs on their surfaces.

[0003] A burr cutting device for wind turbine blades is known from the Chinese patent document with the disclosure number CN210678869U. An electric hydraulic cylinder installed at the bottom of a U-shaped frame pushes and moves a pressure plate. This is useful for limiting and fixing a wind turbine blade whose burr needs to be trimmed, and preventing the blade from shaking during the cutting process and thus damaging the wind turbine blade. The rotation of an installed stepper motor drives a threaded rod to rotate. The rotation of the threaded rod causes a connecting block to reciprocate on the surface of the threaded rod, and the connecting block moves a fixing block, thus facilitating the burr cutting process with the aid of a rotating wheel.

[0004] There are still certain shortcomings in use. When deburring blades, the phenomenon of chip splashing occurs. If chips splash onto the surface of the human body, it will cause damage to the human body and reduce the safety of the cutting device during use. At the same time, the temperature of the part of the blade in contact with a blade will rise sharply during cutting. If the blade and blade cannot be cooled in time, this will result in the surface temperature of the blade being high and easy to cause damage, thus limiting the practicality of the cutting device.

[0018] In the present embodiment, as shown in Fig. 1 and Fig. 4, the nozzle 28 penetrates the through groove 10. A drive motor 12 is mounted on a side surface of the protective cover 5. An output end of the drive motor 12 is fixedly connected to a disc 13, and the surface of the disc 13 is fixedly connected to a circular rod 14. A side surface of the sliding plate 11 is fixedly connected to a support rod 16, the side surface of which is fixedly connected to a slide-on ring 15 arranged on the outer side of the circular rod 14 and slidably connected to the circular rod 14. The surface of the support plate 18 is fixedly connected to a vertical plate 19, the top surface of which is screwed with a screw 20, the bottom of which is fixedly connected to an extrusion plate 21.At this time, the protective cover 5 can be lowered by the air cylinder 17 so that the protective cover 5 abuts the support plate 18, and then the splashing of chips during cutting can be avoided and the safety of using the cutting device can be improved. At the same time, the connecting pipe 7 is cooled by the ice block 27, and then the gas in the connecting pipe 7 can be cooled, so that the cooled gas can be sprayed out via the air pump 9 and the nozzle 28. In addition, the cold air can be evenly sprayed onto the surface of the cutting plate 24 and the blade body 22 to cool the blade body 22 and the cutting plate 24, thus preventing damage to the blade body 22 due to high temperature.

[0019] In the present embodiment, as shown in Fig. 2 and Fig.3, the vertical plate 19 is provided internally with a blade body 22, against the surface of which the extrusion plate 21 rests, with a groove 26 formed in the support plate 18. An electric telescopic rod 4 is mounted on one side surface of the support plate 18, the side surface of which is fixedly connected to a movable plate 25, on the upper side of which a stepping motor 23 is mounted.
