Axial adjusting device of grooving saw for board cutting of woodworking

Abstract

The invention discloses an axial adjusting device of a grooving saw for board cutting of woodworking. The axial adjusting device comprises a support and an adjusting mechanism arranged on the support. The adjusting mechanism comprises a pull rod, a flat gasket, a wedge-shaped plate, a fixing sleeve, a locking nut, a grooving saw fixing shaft, a grooving saw fixing base and a pressing spring. One side of the wedge-shaped plate is provided with an inclined groove, and the pull rod is arranged at the lower end of the inclined groove of the wedge-shaped plate. The pressing spring, the flat gasket, the wedge-shaped plate, the fixing sleeve and the locking nut are sequentially arranged on the grooving saw fixing shaft, and the wedge-shaped plate is arranged on a sliding groove on the grooving saw fixing shaft. The grooving saw fixing shaft is arranged on the grooving saw fixing base and fixed on the support. The axial adjusting device overcomes the defect that an eccentric structure is small in adjusting range and inconvenient to adjust, overcomes the shortcoming that a threaded transmission mechanism is large in an adjusting gap, is convenient for operators to use, increases an adjusting range, reduces unstable factors of adjusting, enables adjusting to be correct and labor-saving, and is wide in the adjusting range.

Description

technical field [0001] The invention relates to a woodworking machine, in particular to an axial adjustment device for a woodworking board grooving saw. Background technique [0002] Woodworking enthusiasts have higher and higher requirements for woodworking machines. They hope that the machines are easy to operate, stable in performance, durable, and safe. At the same time, the requirements for the accuracy of the machines are gradually increasing. As the existing woodworking factories are facing problems such as lack of skilled labor and increased labor costs, woodworking factories have higher and higher requirements for the precision of woodworking machines, and require the machines to be easy to operate, stable in performance, durable and safe. Under the requirements of these two groups, the requirements for woodworking panel saws with slotting saw structures are getting higher and higher. Grooving Saw The slotting function of the woodworking panel saw can avoid the phe...

AI Technical Summary

Problems solved by technology

The disadvantage of eccentric mechanism adjustment is that the adjustment amount is relatively small, and sometimes it cannot be adjusted until the slotting saw blade and the main saw blade are on the same plane. The work efficiency is low, the wood surface quality is not high, and the wood consumption is high

The greater the deviation between the two, the lower the work efficiency, the worse the wood surface quality, and the higher the wood consumption

At the same time, due to the limited space of the machine, it takes time and effort to adjust, and the adjustment resistance is also very large

The disadvantage of the thread transmission adjustment mechanism is that the mechanism is complex, the processing is difficult, and the clearance of the thread transmission itself will be unstable. Although the adjustment speed is faster than that of the eccentric mechanism, the clearance of the thread transmission itself will cause the saw blade to be stressed during use. saw blade becomes unstable
