Description
Technical field
The utility model relates to sander, especially relates to a kind of modified sander grinding head.
Background technology
Metal product, especially metallic aluminium goods or Al-alloy products are generally obtain crude green body by casting in a mold after metal melting, then carry out the process such as deburring punching by machined, machine-shaping, the product obtained also needs to adopt sander sanding and polishing, removes surface spikes and out-of-flatness place.
Existing sander generally comprises drive unit and grinding head, and drive unit drives grinding head to rotate, polishing product surface, and the grinding head of existing sander generally comprises plane of grinding wheel, plastic surface etc., and these are inapplicable when polishing metal surface.
Summary of the invention
The purpose of this utility model is exactly to overcome the defect and the modified sander grinding head that provides a kind of life-span high, safe and reliable that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of modified sander grinding head, sander comprises work top, be fixed on the fixed support on work top, the drive unit that fixed support is installed, the grinding head that drive unit is arranged, it is characterized in that, described grinding head comprises connecting rod, be inserted in the wire bundle of one, connecting rod, be enclosed within the sleeve in wire bundle, described connecting rod is hollow stem, its one end is arranged on drive unit, the other end is inserted with wire bundle, described jacket casing is in wire bundle, the length of wire bundle bared end is made to be 5 ~ 15mm.
Described wire bundle is made up of the wire of many equal length and diameter, is inserted in connecting rod by interference fit.
Described diameter wiry is 0.1 ~ 0.5mm, and length is 40 ~ 80mm, and the diameter of wire bundle is 12 ~ 15mm.
Described sleeve one end is inserted in bottom connecting rod, by the tensional fixation of wire bundle.
Internal diameter and the woven wire external diameter of described sleeve match.
Compared with prior art, the utility model has the following advantages: the utility model adopts wire bundle to be grinding head, when High Rotation Speed, the wire bundle of exposed portion is fan-shaped distribution, can effectively polish to metal product surface, and the length of wire bundle bared end is 5 ~ 15mm, on the one hand can wire not easy fracture, even if fracture also due to the design of sleeve, can not produce undue splashing on the other hand, improve security performance, and use birthday noodle can also be improved.
