Steel heat-insulation fireproof door angle grinder capable of continuously grinding fillets

Abstract

The angle grinder comprises an angle grinder body and a grinding wheel, a connecting cover is fixed to the upper end of the angle grinder body in a threaded mode, integrally-formed connecting columns are arranged in the middles of the left side and the right side of the connecting cover, and the angle grinder body is mounted in a mounting groove of a supporting seat through the two connecting columns; the right connecting column extends out of the right side of the supporting seat and is connected with an angle adjusting mechanism, the angle adjusting mechanism is covered with a protective shell, a first angle limiting groove is formed in the protective shell, an adjusting handle is arranged on the angle adjusting mechanism and rotates along the first angle limiting groove on the outer side of the protective shell, and a rotating nail is installed on the rear side of the supporting seat and located at the adjusting handle in a threaded mode. A supporting nail is inserted in the side face of the rotating nail and extends to the position below the adjusting handle for limiting, and a handle is fixed to the middle of the lower end of the supporting base; the angle of the angle grinder body is adjusted through the gear-driven angle adjusting mechanism, 90-degree rotation of the grinding face above the grinding wheel is achieved, and round corner grinding is facilitated.

Description

technical field [0001] The invention belongs to the technical field of angle grinding equipment, and in particular relates to an angle grinder for steel heat-insulating and fire-proof doors that can continuously grind rounded corners. Background technique [0002] Angle grinder, referred to as angle grinder, also known as grinder or disc grinder, is an abrasive tool used for cutting and grinding FRP. Angle grinder is a portable electric tool that uses fiberglass for cutting and grinding. It is mainly used for cutting, grinding and brushing metal and stone. [0003] However, due to the thick wall of the steel heat-insulated fire door, the door body is very heavy, especially for the temporary grinding of rounded corners when the fire door is installed and used. The large angle grinder for fire doors is inconvenient to carry and transport, and the workers usually carry Portable angle grinders are conventionally used for cutting and grinding. However, when this angle grinder gr...

Problems solved by technology

[0003] However, due to the thick wall of the steel heat-insulated fire door, the door body is very heavy, especially for the temporary grinding of rounded corners when the fire door is installed and used. The large angle grinder for fire doors is inconvenient to carry and transport, and the workers usually carry Portable angle grinders are conventionally used for cutting and grinding. However, when this angle grinder grinds rounded corners, the angle cannot be adjusted, and it is difficult to determine the grinding angle. It can only be adjusted by turning the wrist, but it cannot be rotated repeatedly for continuous grinding. Therefore, it is necessary An angle grinder for steel heat insulation and fire doors that can continuously grind rounded corners
