Description
- The present disclosure relates to a holding device. More particularly, the present disclosure relates to a cutting tool holding device for a road planer.
- A cutting tool holding device is used to hold a cutting tool and configured to be attached to a road planer for cutting, mining, excavating the ground or applying a surface roughness treatment to a road.
- Conventionally, the cutting tool holding device includes a base and a cutting tool holder for receiving a cutting tool. The base is fixed on a peripheral surface of a working member (such as a roller) of a machinery (such as a road planer), and the cutting tool holder is engaged with the base by some fastening members. The cutting tool received in the cutting tool holder is mounted along a tangent of the base for facilitating the excavating or cutting operations applied to the ground. In the working process of the aforementioned machinery, an excavating operation is first applied to a processed material (such as concrete or asphalt over a road) by the cutting tool, as the roller rotates, a cutting operation is then applied to the ground by the cutting tool so as to destroy the processed material.
- In general, the processed material is solid and stiff, and a reaction force generated from the processed material during the working process will exert on the cutting tool. Thus the cutting tool working on it only has a rather limited lifetime. Furthermore, when the base and the cutting tool holder are not firmly engaged, serious damages caused by the reaction force occur in the cutting tool holder and the base. As a result, the cutting tool holder and the base are also in need of the frequent replacement. Consequently, the maintenance cost of the cutting tool holding device is high in the art.
- Therefore, it is important to reinforce the engagement between the base and the cutting tool holder and increase a load value of the base and the load value of the cutting tool holder for the reaction force of the base and the cutting tool holder for prolonging the life span of the cutting tool holding device so as to reduce the maintenance cost thereof.
- Furthermore, the scrap of the road surface during the working process of the road planer will be accumulated in front of the cutting tool (e.g. the scrap is dirt, gravel, concrete or asphalt). Due to the cutting tool must be forced to continue working action against the road surface, but the accumulated scrap in front of the cutting tool will produce interference and resistance, and therefore the road planer will reduce the drilling efficiency and waste energy. In addition, the road planer must always be carried out each of the cutting tools cleaning and checking, and the work of the road planer must often wait to clean up not only wasting the human cost, also wasting of time. Therefore, the foregoing problems are the road planer industry's improvement goals,
