Tapping machine

Abstract

A tapping machine is provided with a machine body, the machine body is provided with a main shaft capable of up-down movement, a rotary shaft capable of rotation and synchronous movement is pivoted in the main shaft, one end of the machine body is provided with a driving element capable of controlling rotation speed and rotation direction; a rotary shaft middle section of the main shaft is provided with a shaft sleeve pivoted on the machine body; the machine body is provided with a fixed seat for going-through of an upper end of the rotary shaft corresponding to the upper part of the main shaft; a cylinder body is disposed in the machine body, and the cylinder body is provided with a telescopic rod capable of rising and falling due to gas pressure or oil pressure source. The tapping machine is easy to disassemble, relative components are exposed, maintenance, component change and detachment assembly of the tapping machine are facilitated, stability and accuracy of action are improved, service lifetime is prolonged, rapid movement can be performed, movement time of knife feeding and retracting idle running can be shortened, unnecessary abrasion is reduced, and machining accuracy is ensured.

Description

technical field [0001] The invention relates to a feed driving technology of a tapping machine, in particular to a tapping machine capable of quick action in an empty stroke, which further has the convenience of disassembly and maintenance. Background technique [0002] The general tapping machine is mainly improved from the drilling machine. Its operation process: first, let the spindle move the tapping tool to the top of the workpiece [commonly known as the empty stroke of the tool]. Then, make the tapping knife rotate and feed at a slow speed to perform the tapping action [generally called the working stroke of the knife]. Afterwards, after the predetermined working depth is completed, the tapping tool is reversed and withdrawn from the workpiece [generally referred to as the retracting working stroke]. Finally, let the spindle drive the tapping tool back to its original position [generally called the empty stroke of tool retraction]. [0003] In order to take into acco...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned method can make the empty stroke of the knife advance and retract move quickly, it needs to drive the rack through the worm gear regardless of manual feed or automatic feed. To meet the needs of fast movement, at the same time, the connection and drive of the mechanism will cause wear of the components, which will affect its subsequent service life and processing accuracy

In addition, the main components of the existing tapping machine are all installed inside the machine body, which is a closed design, so it is extremely inconvenient to assemble, and when there is a need for maintenance and replacement of parts, there are also many troubles and even damage. , Invisibly increase the maintenance cost and shorten its service life

[0005] The reason is that the inventor aims at the problem that the moving speed of the aforementioned tapping machine is limited and easy to wear and difficult to disassemble when advancing and retracting the empty stroke, based on years of experience in related industries, and actively seeks a solution. Through hard research and development, we finally successfully invented a tapping machine to overcome the troubles and inconveniences caused by insufficient moving speed, easy wear, and difficult disassembly and assembly.
