Description

Technical Field

[0001] This utility model relates to the field of tool setting technology, and in particular to an automatic tool setting mechanism for machining. Background Technology

[0002] Tool setting is a core process term in lathe machining for determining the position of the program origin in the machine tool coordinate system. It establishes the workpiece machining datum by aligning the tool setting point with the tool position point. Its principle is based on the tool trial cutting or the measurement of the mechanical origin and the workpiece coordinate system by the tool setter.

[0003] Currently, tool setting methods mainly include trial cutting and automatic tool setting. However, they still have the following shortcomings: during the tool setting process, trial cutting mainly relies on the operator's experience, which has low accuracy and is prone to errors. Automatic tool setting uses sensors to automatically record the tool position, but if the tool setting fails on the first attempt, the tool position is not recorded. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing an automatic tool setting mechanism for machining, thereby reducing tool setting errors and improving tool setting accuracy and efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic tool setting mechanism for machining, comprising: A lateral moving part is installed on the processing equipment; A longitudinal moving part is disposed on a transverse moving part, and the transverse moving part is used to drive the longitudinal moving part to move laterally; A lifting part is provided at the bottom of the longitudinal moving part. The bottom of the lifting part is provided with a cutting tool. The longitudinal moving part and the lifting part are used to drive the cutting tool to approach the workpiece in the longitudinal and vertical directions. The lifting component is located at the bottom of the longitudinally moving part; The tool setting unit is located at the bottom of the lifting component. Its lateral movement part, longitudinal movement part, and lifting component are used to drive the tool setting unit closer to the workpiece to assist the tool in tool setting with the workpiece.

[0007] Furthermore, the transverse tool setting member includes an outer tube disposed on a connecting rod and an inner tube disposed on the outer tube, and the outer tube is provided with a spring for connecting the inner tube; It also includes a pressure plate installed on the inner tube and a first displacement sensor installed on the pressure plate.

[0008] Furthermore, the lateral moving part includes a first fixed box and a mounting plate disposed on the first fixed box; It also includes first support members symmetrically arranged on the first fixed box; It also includes a drive unit disposed at the end of the first fixed box and a first lead screw disposed on the first fixed box for being driven by the drive unit, wherein the first lead screw is provided with a first lead block.

[0009] Furthermore, the first support member includes a first slide rail body disposed on the first fixed box and a first slider body disposed in the first slide rail body; It also includes a first L-shaped rod disposed on the first slider.
