Technical Field

The utility model relates to a polisher technical field, concretely relates to polish head for being used for polishing wind-powered electricity generation blade.

Background

The wind power blade needs to be polished in the production and manufacturing process so as to polish the surface of the wind power blade to obtain required roughness, thereby facilitating subsequent paint spraying operation and improving the blade manufacturing quality. At present, when wind power blades are polished, manual polishing is mostly adopted, generally 8-10 polishers are needed for polishing one impeller, the mode is adopted, the labor workload is large, the efficiency is low, and due to the existence of human factors, the polishing is often inconsistent.

Disclosure of Invention

To the technical problem that exists at present, the utility model provides a head of polishing to improve wind-powered electricity generation blade's the efficiency of polishing and the quality of polishing.

In order to achieve the purpose of the invention, the utility model provides the following technical scheme:

the grinding head comprises a rack, wherein a position on one side of the rack is rotatably connected with a grinding wheel along the horizontal direction, the material of an outer ring of the grinding wheel is the same as that of a workpiece to be ground, the rack is connected with a speed reducer through a connecting plate, the input end of the speed reducer is connected with a motor, and the output end of the speed reducer is in transmission connection with a central shaft of the grinding wheel through a transmission mechanism.

By adopting the technical scheme, the motor drives the speed reducer, the transmission mechanism and the polishing wheel to rotate to polish a workpiece to be polished during use, traditional manual polishing operation is replaced, polishing efficiency and polishing quality are improved, and meanwhile, the polishing head is simple in overall structure, convenient to replace parts and good in practicability.

Preferably, the grinding wheel is a brush roller or a brush wheel.

Preferably, two ends of the frame are respectively connected with a supporting wheel, the grinding wheel is located between the two supporting wheels, the axial line of the two supporting wheels and the axial line of the grinding wheel are on the same straight line, and the diameter of the two supporting wheels is smaller than that of the grinding wheel.

Adopt this scheme, two supporting wheels make things convenient for the removal of head of polishing on the one hand, on the other hand because the wheel of polishing can appear expanding to both sides in the use, two supporting wheels can be with the brush on the wheel of polishing when the extension between two supporting wheels, avoided the wheel brush of polishing to expand at will to both sides, guaranteed the distance of polishing and the quality of polishing, simultaneously because the supporting wheel diameter is less than the wheel diameter of polishing, two supporting wheels still can support the pressure to wind-powered electricity generation blade before polishing, avoided the random removal of the in-process wind-powered electricity generation blade of polishing.

Preferably, the transmission mechanism comprises a first transmission wheel connected to the output end of the speed reducer, a second transmission wheel connected to the central shaft of the grinding wheel, and a transmission belt connecting the first transmission wheel and the second transmission wheel.

Preferably, a protective cover is arranged at the upper end of the rack close to the connecting plate, and the part of the transmission mechanism, which is positioned at the upper end of the rack, is positioned in an area enclosed by the protective cover and the connecting plate.

By the arrangement, the safety of the operation area is improved.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses replaced traditional manual work operation of polishing, improved the efficiency of polishing and the quality of polishing, should polish head overall structure simple, durable, conveniently change simultaneously and polish wheel and other parts, have better practicality.
