Description

TECHNICAL FIELD

[0001] The utility model relates to polishing device technical field, specifically an arc manual polishing device suitable for aluminium round pipe. BACKGROUND

[0002] In the production process of aluminium round pipe, burrs or unevenness can be left on the surface due to the processing technology, and polishing is needed to improve it. Polishing includes manual polishing or mechanical polishing. Manual polishing can be used for fine processing of specific parts of the aluminium pipe to ensure that the surface quality meets the standard. Manual polishing can also help improve the reflectivity and corrosion resistance of the aluminium pipe. Through polishing, the surface of the aluminium pipe becomes smoother, which can better reflect light and improve its reflectivity and decorative effect.

[0003] However, the existing manual polishing is mostly through handheld abrasive sheet / plate for polishing. However, the abrasive sheet / plate does not fit the arc surface of the aluminium round pipe well, and the contact area is small, so the polishing efficiency is low, the polishing time is long, and the labor intensity is high, which needs to be improved.

The outer frame is fixed with the replaceable polishing plate through the screw. The two sides of the replaceable polishing plate are pressed by the two pressing blocks. An operating handle is installed on the outer frame.

[0007] As a further scheme of the utility model, the bottom surface of the pressing block is inclined, and the two pressing blocks are oppositely arranged.

[0008] As a further scheme of the utility model, a sliding head for limiting sliding cooperation with the guide rail is installed in the sliding groove of the pressing block.

[0009] As a further scheme of the utility model: the surface of the replaceable polishing plate is a circular arc surface.

[0010] As a further scheme of the utility model: the bottom surface of the operation handle is provided with anti-skid protrusions.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] 1, the utility model discloses a replaceable polishing plate is designed in a circular arc shape, which can be more closely attached to the surface of an aluminum round pipe, making the polishing more uniform.

[0013] 2, the utility model discloses a threaded hole and a screw, the screw and the threaded hole can be quickly disassembled and combined with the exoskeleton, so that personnel can replace the polishing plate to adapt to aluminum round pipes of different specifications.

[0014] 3, the utility model discloses a screw rod adjusting assembly and a pressing block, the screw rod adjusting assembly can drive the pressing block to move horizontally at the bottom of the exoskeleton, and the distance between the two pressing blocks can be adjusted to press the replaceable polishing plate on both sides, so that the replaceable polishing plate is not easy to shake and deviate during manual polishing, and the polishing effect is better.
