Automatic turning mechanism on turning saw

Abstract

The invention provides an automatic turning mechanism on a turning saw, which comprises a grinding assembly consisting of a motor and a grinding wheel, wherein the grinding assembly is fixed at the front end of a main shaft through a grinding head fixing member, the main shaft is rotatably arranged on a corner supporting seat, the rear end of the main shaft is connected with a corner lever, the lower end of the corner lever is connected with a piston of a cylinder, the cylinder is horizontally and movably arranged on the corner supporting seat and drives the corner lever and the main shaft tomake a reciprocating rotating motion through a telescopic motion of the piston on the cylinder, and further the main shaft drives the grinding assembly on the grinding head fixing member to make an up-down turning motion, all parts are uniformly stressed and operate stably without being easily damaged during the turning motion and have long service life; meanwhile, the automatic turning mechanismhas simple integral structure, and is convenient for installing and debugging; in addition, because the cylinder is horizontally arranged, all moving parts have smaller volume and smaller motion radius, the integral structure has smaller volume and is convenient for installing and transporting.

Description

Technical field: [0001] The invention relates to a reversing saw for automatic grinding of a panel saw, in particular to an automatic reversing mechanism on the reversing saw. Background technique: [0002] In the prior art, as disclosed in patent 200820180499.9, there is an automatic overturning mechanism for a hand saw processing machine tool. Composed of gears, the expansion and contraction of the piston on the drive cylinder drives the drive rack to move up and down, and then drives the driving gear and driven gear to reciprocate and rotate, and the grinding device and motor connected to the driving gear and driven gear move up and down accordingly. Turning down to complete the grinding of the left and right tooth surfaces of the opponent’s panel saw. In this process, the user only needs to clamp once, which saves time and effort, improves work efficiency and reduces labor costs. However, this The structure also has disadvantages: [0003] Since the structure is driven...

AI Technical Summary

Problems solved by technology

[0003] Since the structure is driven by the cooperation of the driving rack and the driving gear and the driven gear, and the driving rack is vertically arranged, the volume of each component is relatively large, which makes the overall volume of the structure large, which is not conducive to transportation and transportation. Installation, and at the same time, due to the weight of the grinding device and the motor, the driving rack is subjected to a greater force when the grinding device and the motor are turned up, and less force when turned down, which is likely to cause unstable operation and drive the rack. In addition, the structure also has additional components such as guide sliders and anti-backlash racks, which increases the complexity of the structure and is very difficult to install and debug.
