Embodiment Construction

[0039] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0040] A sander is a mechanical device used to smooth a plate, an equipment surface or a building surface. Existing sanders mainly include circular sanders and flat sanders. like Figure 1 to Figure 5 As shown, the present invention provides a sander, which includes a housing 1 , a power mechanism 4 , a grinding mechanism 2 and a damping mechanism 5 . The bottom end of housing 1 has installation opening, and the shape of installation opening can be circular, square or other shape, and the setting of installation opening is for the convenience that power mechanism 4 is installed in the inside of housing 1, and grinding mechanism 2 is arranged on installation port. In order to facilitate the user's hand-held operation, such as figure 1 As shown, an annular handle 101 is provided on the housing 1, a...

Abstract

The invention discloses a sanding machine, and belongs to the technical field of grinding equipment. The sanding machine comprises a shell, a motor shaft, a grinding mechanism and damping mechanisms,wherein the motor shaft can rotate relative to the shell by taking a first axis as an axis, the grinding mechanism is fixedly connected with the motor shaft, and the damping mechanisms elastically abut against the upper surface of the grinding mechanism. The damping mechanisms are arranged to comprise pressing pins and buffering pieces, when the grinding mechanism and the abutting pins rub with each other, the buffering pieces are used for providing buffering for the abutting pins, so that the mutual abrasion between the grinding mechanism and the damping mechanisms can be effectively reduced,the service life of the damping mechanisms and the grinding mechanism is prolonged, the grinding quality of the grinding mechanism is improved and the damping effect of the damping mechanisms is improved.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a sander. Background technique [0002] A sander is a mechanical device used to complete sanding work. Sanding is a synonym for grinding, which refers to processing some materials and objects that are uneven, uneven in thickness, or do not meet the process requirements into standard parts with smooth surface, uniform thickness, and meeting various process requirements through mechanical equipment. Optomechanics are widely used in many fields such as machinery and home decoration. [0003] The sanding machine includes a power mechanism and a grinding mechanism, and the grinding mechanism rotates under the drive of the power mechanism. When the existing sanding machine is in initial contact with the workpiece to be polished, the speed of the grinding mechanism is faster and the resistance received is smaller. At the moment of contact with the workpiece, it is easy to c...
