High-precision multi-shaft automatic turning process of wood

Abstract

The invention provides a high-precision multi-shaft automatic turning process of wood. The high-precision multi-shaft automatic turning process comprises the steps that firstly, one end of a rodlike wood workpiece is inserted between clamping corner blocks of a self-centering feeding mechanism, the clamping corner blocks are close to each other and do synchronous movement, and the rodlike wood workpiece is subjected to self-centering clamping; then a feeding motor drives a first supporting frame to slide close to a first sliding block along a feeding guide rod until the wood workpiece clampedby the clamping corner blocks is conveyed into the space between a first tip and a second tip, and the rodlike wood workpiece and the two clamping ends of a clamping mechanism are coaxial; then the clamping mechanism is started to operate, and the two ends of the rodlike wood workpiece are clamped; then the feeding motor is started to rotate reversely, a clamping motor is started to rotate reversely, and the self-centering feeding mechanism is reset; and finally, a spindle motor drives the rodlike wood workpiece to rotate at high speed, a transverse driving mechanism and a lifting driving mechanism cooperate to drive a turning tool to carry out feeding in the transverse direction and the longitudinal direction, and the rotary rodlike wood workpiece is cut through the turning tool.

Description

technical field [0001] The invention relates to a woodworking lathe, in particular to a high-precision multi-axis automatic turning process for wood. Background technique [0002] Woodworking lathes are used to process the outer circle, end face, grooving and boring of wood workpieces. The wood workpiece is clamped in the chuck, and the chuck performs self-centering clamping on the rod-shaped wood workpiece; the second is to support the rod-shaped wood workpiece between the two tips of the main shaft and the tailstock, and the tip passes through the center hole of the end surface of the rod-shaped wood workpiece Realize the centering of the bar material, and then the chuck / spindle drives the bar-shaped wood workpiece to rotate. There are certain defects in the clamping of ordinary woodworking lathes.

Problems solved by technology

[0002] Woodworking lathes are used to process the outer circle, end face, grooving and boring of wood workpieces. The wood workpiece is clamped in the chuck, and the chuck performs self-centering clamping on the rod-shaped wood workpiece; the second is to support the rod-shaped wood workpiece between the two tops of the main shaft and the tailstock, and the top passes through the center hole of the end surface of the rod-shaped wood workpiece Realize the centering of the bar, and then the chuck / spindle drives the bar-shaped wood workpiece to rotate. There are certain defects in the clamping of ordinary woodworking lathes. The self-centering clamping of the bar-shaped wood workpiece through the chuck is only suitable for shorter For wood workpieces, if the chuck is used to clamp a long wood workpiece, the rotation of the chuck will cause the cutting end of the wood workpiece to vibrate greatly, which will seriously affect the machining accuracy of the wood workpiece; the clamping is performed by the two tops of the main shaft and the tailstock Although it is suitable for longer rod-shaped wood workpieces, it is necessary to open a center hole on the end face of the rod-shaped wood workpiece in advance. In order to overcome the above-mentioned clamping defects, our team designed a woodworking lathe with ingenious structure and simple principle for automatic feeding and turning processing. method, which can realize self-centering clamping for longer / shorter rod-shaped wood workpieces, and does not need to open a center hole in the end face of the rod-shaped wood workpiece
