Embodiment 1

[0033] see Figure 1-9 , in an embodiment of the present invention, a stirring type saw chain fatigue test device includes a chassis, a box body, a box cover and a chainsaw 22, the box is filled with wood blocks, and the chainsaw 22 is inserted into the box. The chainsaw 22 is constantly sawing wood so that it is tested for fatigue.

[0034] The fatigue test device also includes a stirring mechanism driven by the motor 23, and the stirring mechanism is used to drive the block when the chain saw 22 is stuck in the process of sawing wood, so as to drive the block to shake, so as to overcome the blockage of the chain saw and the block The problem.

[0035] The underframe includes an underframe angle steel 1, an underframe channel steel 2, an underframe supporting plate 3, an underframe bearing block 4 and an underframe bearing 5, and the underframe angle steel 1, underframe channel steel 2, and underframe supporting plate 3 and the bottom frame bearing seat 4 are formed by weld...

Embodiment 2

[0040] Please refer to the stirring shaft 10 in the figure, in the embodiment of the present invention, a stirring type saw chain fatigue test device, on the basis of embodiment 1, an electrical control system is also connected under the cover, and the electrical control system includes control button, programmable logic controller (PLC), analog-to-digital converter (A / D), speed governor and acceleration sensor, and the programmable controller and control button, analog-to-digital converter, speed governor and acceleration sensor are both By electrical connection, the control button and the speed governor are all electrically connected with the motor 23, and the programmable controller is used as the main control device to control the start / stop of the chain saw 22, the start / stop, speed regulation and operation of the motor 23. Forward and reverse control: the acceleration sensor is arranged on the support plate 21, and by performing real-time detection of the vibration accele...

Abstract

The invention discloses a stirring saw chain fatigue test device, comprising a bottom frame, a box body, a box cover and a chain saw. The fatigue test device further comprises a stirring mechanism driven by a motor, the lower part of the box cover is also connected with an electrical control system, and the electrical control system comprises a control button, a programmable controller, an analogto digital converter, a speed governor and an acceleration sensor. According to the scheme of the invention, the phenomenon of frequent shutdown caused by the blockage of wood blocks in a saw chain fatigue test is eliminated, and the test efficiency is obviously improved; and the steering and rotating speed of a stirring motor can be controlled during the test, so that the test conditions can be more stable; and the test device can automatically perform timing and judge the test state.

Description

technical field [0001] The invention relates to the technical field of forestry machinery, in particular to a stirring type saw chain fatigue test device. Background technique [0002] Chainsaws, including chainsaws, electric chainsaws and sawing mechanisms in the working heads of logging machines, are essential production tools in the forest harvesting and gardening industries. The cutting part of the chain saw is called the saw chain. The saw chain is a closed chain that is arranged in a certain order by the saw teeth, connecting pieces and guide teeth, and hinged by the chain shaft. The performance of the sawtooth has a great influence on the energy consumption of the chain saw, sawing efficiency, labor intensity of the staff and production safety. Forestry production is temporary and decentralized, and it is not convenient for equipment maintenance during the production process. These production characteristics require the durability of saw chain teeth to be very high,...
