Description

Polisher of removable subassembly of polishing

Technical Field

The utility model relates to a grinding machine with a replaceable grinding assembly, and belongs to the technical field of machining equipment.

Background

In the mechanical processing, after each part is machined, a lot of burrs appear on the surface, and the roughness of the surface cannot meet the requirement of polishing treatment. This requires the use of grinders, many of which are currently used, the most commonly used for grinding planes are wheel grinding and sanding belts, which are inefficient and not uniform enough. The abrasive belt polishing needs to be provided with a tension wheel, the existing tension wheel is inconvenient to adjust and not accurate enough, the abrasive belt needs to be tightened when a workpiece is polished, the polishing contact place cannot collapse, and the polishing effect can be guaranteed.

The utility model aims to solve the defects in the prior art, and provides the polishing machine with the replaceable polishing assembly, the tensioning wheel is convenient and accurate to adjust, the abrasive belt at the polishing contact position cannot collapse, and the polishing effect is better.

The utility model is realized by the following technical scheme:

namely a polisher with a replaceable polishing component, which comprises a vertical plate, wherein the vertical plate is fixed on a base, two rollers are arranged at the upper end of the vertical plate and are respectively an upper driven roller and an upper driving roller, the upper driving roller is connected with a motor to provide power, a lower driven roller is arranged below the upper driven roller, a sanding belt is wound on the three rollers, an operation table is fixedly arranged on the left side of the vertical plate, a mounting frame is fixedly arranged on the front end surface of the vertical plate, a slideway is arranged on the mounting frame, a slideway is also arranged on the vertical plate at the position corresponding to the position of the slideway on the mounting frame, a tensioning roller is arranged between the two slideways, a guide plate is arranged at the right end of the mounting frame, a threaded rod is arranged through the guide plate, a hand wheel is arranged at the right end of the threaded rod, a spring is connected between the threaded rod and a rotating shaft of the tensioning roller, and a roller frame positioned between the two driven rollers is fixed on the vertical plate, a row of rollers are arranged in the roller carrier.

The tensioning roller is convenient and accurate to adjust and can adapt to the abrasive belt with larger error in length; the abrasive belt at the grinding contact position can not collapse, and the grinding effect is better.

Preferably, the outer end of the rotating shaft of the tension roller is sleeved with a ring, the left end of the threaded rod is also sleeved with a ring, the ring is provided with an annular groove, and two ends of the spring are sleeved on the two rings.

Further preferably, the left ends of the upper driven roller and the lower driven roller and the left end of the roller are located on the same vertical plane.

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