Elastic grinding head and grinding machine

Abstract

The invention discloses an elastic polishing head. The elastic polishing head comprises a vacuum bar, an inner cavity is formed in the vacuum bar, an elastic polishing head body is arranged at the top end of the vacuum bar and provided with a first through hole, and the first through hole is communicated with the inner cavity of the vacuum bar. The invention further discloses a polisher comprising the elastic polishing head. The inner cavity of the elastic polishing head is communicated with a vacuumizing device. By sucking air from the inner cavity of the vacuum bar or blowing air to the inner cavity of the vacuum bar, abrasive paper can be automatically replaced or removed, so that the automation degree is high. The elastic polishing head is applicable to various work-pieces, so that the cost is greatly lowered. The polisher is provided with a mechanical arm so that operating personnel can be far away from the severe operating environment.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to an elastic grinding head and a grinding machine. Background technique [0002] In the prior art, the grinding head is rigid, and the grinding head grinds on the R angle and the groove of the workpiece, and with the increase of the grinding time, the wear condition becomes more and more serious, the grinding head will be deformed, and the deformation of the grinding head will cause tolerance and shorten the service life. shortened, the effect of grinding the workpiece becomes worse. [0003] Because in the prior art, the grinding head is made of rigid material, the rigid grinding head cannot be automatically extruded and adjusted according to the shape of the workpiece, so that the grinding head cannot be well adapted to different R angles and grooves. [0004] In addition, abrasive consumables are made of sandpaper. In the prior art, the sandpaper is wrapped outside the g...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, the grinding head is rigid, and the grinding head grinds on the R angle and the groove of the workpiece, and with the increase of the grinding time, the wear condition becomes more and more serious, the grinding head will be deformed, and the deformation of the grinding head will cause tolerance and shorten the service life. shortened, the effect of the ground workpiece becomes worse

[0003] Because in the prior art, the grinding head is made of rigid materials, the rigid grinding head cannot be automatically squeezed and adjusted according to the shape of the workpiece, so that the grinding head cannot be well adapted to different R angles and grooves

[0004] In addition, abrasive consumables are made of sandpaper. In the prior art, the sandpaper is wrapped outside the grinding head. Generally, the connection between the sandpaper and the grinding head is through adhesive bonding, or the sandpaper is clamped by slotting on the grinding head. The problem brought by this method is that the process of removing the sandpaper after use is complicated, and the assembly process is complicated, time-consuming and laborious
