Description

Lathe Z axle positioning jig

Technical Field

The utility model relates to a lathe work piece processing technology field specifically is a lathe Z axle positioning jig.

Background

When a lathe workpiece is machined, the clamping length cannot be accurately controlled, and the vernier caliper needs to be used for repeated clamping measurement. When a long workpiece is subjected to segmented processing, multiple clamping cannot be guaranteed; for example:

1. clamping the workpiece for the first time, wherein the length of the workpiece is 30mm, and processing the workpiece for 28mm (Z-28.);

2. clamping the workpiece for the second time, wherein the length of the workpiece is 60mm, and processing is 58mm (28 mm is finished in the first clamping);

3. clamping the workpiece for the third time, wherein the workpiece is 90mm in length and 88mm in processing (58 mm is already finished in the first and second processing);

thus, a workpiece with the length of 88mm is machined. However, during machining, the length of each clamping is not well controlled, a vernier caliper is needed for preliminary measurement, trial cutting is conducted by a cutter for accurate measurement, efficiency is low, operation difficulty is high, accuracy is low, errors are large, and product defects are increased.
