Abstract

The present invention proposes a CNC precision thread rolling machine and a multi-head screw for automobiles. The invention includes a base and a workbench arranged on the base for processing the lead screw. The workbench is provided with a transmission unit for rolling the lead screw. The transmission unit is arranged on both sides of the lead screw, and a feed unit is arranged on one side of the workbench. The power output end of the feed unit is connected to one of the transmission units. The worktable is provided with a straight line for the feed unit to move linearly. Guide rail, the feed unit moves linearly on the linear guide rail, driving one of the transmission units to approach or move away from the other transmission unit. The present invention realizes three-axis interlocking and repeatable precise positioning, each axis performs differential compensation, small repeated positioning error, low product defect rate, simple control, and realizes the precision of multi-head screw processing.

Description

technical field

[0001] The invention belongs to the field of thread rolling machines, in particular to a numerically controlled precision thread rolling machine. Background technique

[0002] The thread rolling machine is a multi-functional cold extrusion forming machine tool. The thread rolling machine can process the thread, straight grain, and oblique grain rolling of the workpiece in a cold state within its rolling pressure range; straight teeth, helical teeth and helical spline gears rolling; straightening, reducing, rolling and various forming rolling. The machine has a safe and reliable electro-hydraulic execution and control system, allowing each working cycle to be selected from three modes: manual, semi-automatic and automatic.

[0003] Chinese utility model patent CN 203791545 U discloses a thread rolling machine, the auxiliary shaft of the thread rolling machine is fixedly mounted with a first motor, one end of the first motor is provided with a first gear, and ...
