Technical Field

The invention belongs to the technical field of moso bamboo chip processing, and particularly relates to a profile modeling self-adaptive tool rest assembly.

Background

At present, along with the continuous improvement of the living standard of people, the decoration demand of wooden furniture, wooden floors and the like in the life of people is higher and higher, the demand is also larger and larger, the global timber shortage is caused, a large amount of forests are felled, and the global environment on which the human beings rely to live is increasingly severe.

The moso bamboo has the characteristics of short growth cycle, hardness similar to that of wood, excellent toughness and the like, so that the moso bamboo is gradually valued by people, and is made into bamboo integrated wood by processing the moso bamboo, so that living appliances such as bamboo furniture, bamboo floors, bamboo cutting boards and the like can be manufactured, the chopping of wood can be indirectly reduced, the ecological environment of the earth is improved, and the moso bamboo is multifunctional.

As shown in fig. 10, however, when the moso bamboo chips are processed by the existing moso bamboo processing equipment, the most salient point of the outer circle diameter is used as a positioning reference, when a milling cutter mills the green surfaces of the moso bamboo, because the center of the milling cutter and the positioning reference surface of the tool holder body are fixed values, as shown in fig. 11, when the green surfaces of the moso bamboo chips with small diameters are cut, the green surfaces of the moso bamboo may be "remained green" due to too small cutting amount; as shown in fig. 12, when the green surface of the large-diameter moso bamboo sheet is cut, the available thickness of the moso bamboo is reduced due to excessive cutting amount, which causes waste of materials; as shown in fig. 13, when the green surface of the irregular round bamboo is cut, the "shade surface" is formed on the bamboo chips due to the insufficient cutting amount.

The three processing conditions can cause the bamboo laminated wood to be unaesthetic in splicing and even cause waste products.
