Assistant locating device of numerical control lathe spindle

Abstract

The invention discloses an assistant locating device of a numerical control lathe spindle. The assistant locating device comprises an adjusting clamp, a mounting part, a locating shaft and a long barrel, wherein the locating shaft and the long barrel are each of a hollow structure. The locating shaft is coaxially mounted in the long barrel, and the length of the locating shaft is larger than that of the long barrel. A flange device used for synchronously fixing the long barrel and the locating shaft is arranged at one end of the long barrel. The mounting part and the adjusting clamp are sequentially arranged at the other end of the long barrel. One end of the adjusting clamp is clamped on the long barrel, and the other end of the adjusting clamp is clamped on the locating shaft. According to the assistant locating device, the locating shaft can be adjusted according to different workpieces, and then locating of different lengths can be achieved by locking the adjusting clamp and the mounting part. Compared with the prior art, when workpieces different in length are machined on a large scale, the stretching length of the workpieces can be adjusted fast, the time of clamping and locating is saved, operation is convenient and fast, and therefore machining efficiency is greatly improved.

Description

technical field [0001] The invention relates to a tooling tool for a numerically controlled lathe, in particular to an auxiliary positioning device for a spindle of a numerically controlled lathe, belonging to the technical field of mechanical processing equipment. Background technique [0002] CNC lathes are large-scale modern machining equipment, generally divided into cutting machine tools and tooling machine tools. With the rapid development of science and technology, CNC machine tools continue to develop towards the trend of intelligence, high speed and precision. When processing the workpiece, the workpiece is placed on the spindle of the CNC lathe, and then the processing operation can only be performed after positioning by the workpiece fixture matched with the spindle. In the prior art, in the field of CNC lathe processing, there are already many and mature tools for positioning and clamping workpieces. For example, the Chinese invention patent application with app...

Problems solved by technology

However, it cannot quickly adjust the protruding length of the workpiece during processing. When a large number of workpieces with different lengths are processed, it is necessary to measure the protruding length of the workpiece every time it is clamped.

The measurement process will not only take a long time and reduce production efficiency, but also the machining accuracy of the workpiece is difficult to guarantee
