A positioning mechanism for processing large-size logs for agriculture and forestry

Abstract

The invention discloses a positioning mechanism for processing large-size logs used in agriculture and forestry, which relates to the technical field of wood processing and includes a support bracket, an outer sleeve, an inner sleeve, a liquid inlet pipe, a piston, a thimble and a driving mechanism. The support bracket is fixed, and the inner sleeve moves to realize the clamping and positioning of one end of the log. Compared with the traditional tailstock positioning method, there is no need to manually shake the handle to realize the movement of the tailstock, only need to pass in hydraulic oil It can be realized, which simplifies the positioning process and saves manpower. At the same time, the top plate first contacts the log, then locks it with the thimble, and finally pressurizes until the pressure reaches the set value to realize the clamping and positioning of the log. The clamping force is more precise, and it also prevents the log from turning due to excessive torque.

Description

technical field [0001] The invention belongs to the technical field of wood processing, and in particular relates to a positioning mechanism for processing large-size logs used in agriculture and forestry. Background technique [0002] In the existing log processing process, machine tools or lathes or similar equipment are often used for clamping and positioning, and subsequent surface processing operations such as peeling and finishing are performed manually or mechanically. [0003] In the process of clamping and positioning large-sized round logs (large diameter and large length) by machine tools, manual rotation of the screw is often used. Although the purpose of clamping can also be achieved, the magnitude of the clamping force is difficult. To be sure, relying more on experience, it is not easy to control, and manual operation is less efficient. Especially for new employees, it is easy to happen that the clamping force of the log is too small to cause eccentricity dur...

Problems solved by technology

[0003] In the process of clamping and positioning large-sized round logs (large diameter and large length) by machine tools, manual rotation of the screw is often used. Although the purpose of clamping can also be achieved, the magnitude of the clamping force is difficult. Definitely rely on experience, it is not easy to control, and manual operation, the efficiency is low

Especially for new employees, it is easy to happen that the clamping force of the log is too small to cause eccentricity during the rotation process, or the clamping force is too large, the hand-cranking process is very laborious, and it is easy to damage the log in the morning

In addition, due to the large size of such logs, during processing, the logs are easily deflected in the axial direction due to excessive torque, or even eccentric, which affects the processing accuracy
