A remote-controlled automatic grinder specially used for surface modification of mechanical equipment

Abstract

The invention discloses a remote-control automatic grinding machine special for surface finishing of mechanical equipment. The remote-control automatic grinding machine special for the surface finishing of the mechanical equipment is provided with an annular permanent magnet, a driving mechanism, a detection mechanism, a wireless remote control device, a wireless receiving device and a switching power supply, wherein the driving mechanism comprises a motor speed reducing device, upper supporting rods, vertical guide rods, connecting rods and lower supporting rods; and the upper supporting rodsare installed on the outer side of the upper end of a shell of motor speed reducing equipment correspondingly, the upper end of each vertical guide rod is installed at the lower part of each upper supporting rod, the inner sides of the lower supporting rods are installed on the outer side of the middle of the shell of a plane grinding machine body correspondingly, guide pipes are arranged in themiddle of the outer side of the vertical guide rods in a sleeve mode, the connecting rods are installed in the annular permanent magnet and in the lower parts of the vertical guide rods correspondingly, the upper part of the detection mechanism is installed in a screw hole, an internal thread pipe is installed at the upper end of the shell of the plane grinding machine body, and external threads of a power output shaft at the lower end of the motor speed reducer is screwed into internal threads of the internal thread pipe. According to the remote-control automatic grinding machine, the surfaceof a rough metal plate can be finished by the remote control of the plane grinding machine body.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a remote-controlled automatic grinder specially used for surface finishing of mechanical equipment. Background technique [0002] Grinder is a widely used power tool in the machinery industry, which is divided into desktop grinder, plane grinder and so on. Among them, the plane grinder used for surface modification of metal sheets of mechanical equipment is mainly used for repairing the rough surface of equipment metal sheets (such as the joint of two steel plates welded on the deck of a ship, and the joint of two steel plates welded by bridge formwork), especially It is widely used in the field of machinery manufacturing equipment. When the existing flat grinder is used, it is necessary to manually hold the grinder body to trim the metal surface; or to operate the flat grinder by a machine tool or a robot, so as to trim the surface of metal plates and the like.

Problems solved by technology

[0004] In order to overcome the disadvantages of the existing plane grinder used for rough surface finishing of metal sheets of mechanical equipment due to the limitation of structure and in practical applications, the present invention provides a tool that can be conveniently attracted by three ring-shaped permanent magnets with large suction force to any work that needs to be operated. The working point, when working, the operator does not need to manually operate the grinder body to repair the rough surface of the mechanical equipment. The wireless remote control device can operate the grinder body without contact. The driving mechanism can make the grinder body gradually descend to the rough surface The surface of the metal sheet is automatically trimmed, and it also has a detection mechanism. When the metal sheet working surface and the metal sheet as a whole are on the same plane, the detection mechanism will control the grinder body to stop working, which can prevent the trimming point from being trimmed downwards too much for the finished equipment. If the quality is affected, it can also notify the operator to repair the next operation point in time through the sound of the sounder, which improves the work efficiency. It is a remote-controlled automatic grinder dedicated to the surface modification of mechanical equipment.
