Flexible polishing device

Abstract

The invention provides a flexible polishing device which comprises a power source unit, an output execution unit and a flexible shaft. An output shaft is arranged in the output execution unit. One end of the flexible shaft is connected with the power source unit, and the other end of the flexible shaft is connected with the output shaft. A grinding head installing part is arranged at the end of the output execution unit. The flexible polishing device further comprises an axial floating unit and / or a radial floating unit. The axial floating unit and / or the radial floating unit are / is arranged between the output execution unit and the power source unit and are / is used for achieving axial floating and / or radial floating of the output execution unit respectively. According to the flexible polishing device, the curve deviation between an absorbing machining path of the axial floating unit and / or the radial floating unit and a machined material is mainly utilized, and burrs on the machined surface are removed flexibly. Meanwhile, as the flexible shaft can transfer high-power power to polish burrs, sprues and weld seams, the range of the machining field is widened.

Description

technical field [0001] The invention relates to a grinding device, in particular to a flexible grinding device. Background technique [0002] Grinding is a very common process in industrial production. Flashes and gates of castings (such as cast iron, cast aluminum, cast steel) and welds in the middle of weldments often need to be ground. At present, most of them are polished by manpower, which is time-consuming and laborious, and the on-site working environment is poor (such as very dusty), and safety accidents occur from time to time, which makes the working environment of the polishing staff quite bad. Nowadays, it is gradually becoming a trend to use robots or other automated equipment for sanding. However, the grinding device of the prior art cannot provide high power. When grinding, the grinding head has a small swing or axial expansion and contraction range, and is generally only used for deburring, but there are still shortcomings in grinding a large number of flas...

Problems solved by technology

However, the grinding device in the prior art cannot provide high power. When grinding, the swing or axial expansion of the grinding head is relatively small. Generally, it is only used for deburring, but there are still shortcomings in grinding a large number of flashes and gates.

[0003] In addition, current grinding devices either only swing or retract
