Positioning device for adjusting saw blade shafts of multi-saw-blade woodworking machine

Abstract

The invention relates to a positioning device for adjusting saw blade shafts of a multi-saw-blade woodworking machine. The positioning device comprises an eccentric wheel mechanism arranged on a box body of the multi-saw-blade woodworking machine. The first saw blade shaft and the second saw blade shaft are vertically and oppositely arranged on the box body. The portions, corresponding to the front mounting shaft hole position and the rear mounting shaft hole position of the first saw blade shaft, on the box body are correspondingly provided with assembling circular holes with the same diameter and tolerance. The two assembling circular holes are correspondingly provided with eccentric wheels matched with the assembling circular holes. A mounting hole for mounting the first saw blade shaft is formed in the eccentric shaft position of each eccentric wheel. The assembling circular holes of the eccentric wheels are internally in a rotatable transition fit. A clamping hole is formed in the outer side of the first saw blade shaft. The side, corresponding to the clamping hole, of the outer side of the box body is provided with a positioning device body for positioning the first saw blade shaft when the saw blade shafts of the multi-saw-blade woodworking machine are adjusted. The positioning device has the beneficial effects that the efficiency of adjusting the saw blade shafts of the multi-saw-blade woodworking machine can be improved, and the time and labor are saved.

Description

technical field [0001] The invention relates to the field of wood processing equipment, in particular to a positioning device for adjusting the saw blade shaft of a multi-saw blade woodworking machine. Background technique [0002] The patent number is 201320075326.1, and the patent name is "A Saw Blade Shaft Eccentric Wheel Adjustment Mechanism for Multi-Saw Blade Woodworking Machine", which discloses a method for adjusting one saw blade shaft of a multi-blade woodworking machine to a set position. , so that the saw blade shaft can be at the farthest position or the closest position relative to the other saw blade shaft, so that saw blade groups of corresponding diameters can be replaced on the two saw blade shafts to process logs of different wood diameters. However, in the process of adjusting the saw blade shaft, it is necessary to manually rotate the eccentric wheel to the corresponding position, and then manually fix the position of the eccentric wheel and install it i...

AI Technical Summary

Problems solved by technology

However, in the process of adjusting the saw blade shaft, it is necessary to manually rotate the eccentric wheel to the corresponding position, and then manually fix the position of the eccentric wheel and install it into the fixing screw to finally locate the saw blade shaft on the eccentric wheel. The saw blade set requires a large external force to stabilize the eccentric wheel, and then another person is needed to install the fixing screw. The whole process is time-consuming and laborious.
