Description

A turning device for machining tight hardware

Technical Field

The invention relates to the technical field of turning devices, and more specifically to a turning device for machining tight hardware parts.

Background technique

During the processing of tight hardware, the hardware needs to be fixed by a positioning device, and then cut to process the outside of the hardware to the required accuracy. During the turning process of the hardware, not only does the hardware need to be rotated to produce threads, etc., but the hardware also needs to be positioned and a cutting device needs to be used to cut longitudinal or transverse grooves.

There are some problems in the use of existing turning devices for hardware processing, as follows:

First, the existing turning device needs to position the hardware through a three-claw positioning plate during the positioning process, but during the positioning process, the worker needs to rotate the three-claw chuck through a designated handle to position the hardware, which is not convenient for quickly positioning the hardware.

Secondly, the existing turning devices are performing rotation processing and horizontal and vertical processing. Due to the different processing procedures, the positioning requirements for hardware are also different. In the process of horizontal or vertical processing of hardware, it is necessary to ensure that the hardware cannot rotate after the positioning is completed, so as to avoid the rotation of the hardware during the slotting process, resulting in the cut positioning groove not being consistent with the expectation, and the processing quality cannot be guaranteed.

Third, the existing turning device will generate a large amount of metal debris splashing during the processing, which will cause harm to the operator and is inconvenient for the user to operate. If a splash guard is provided, it will be inconvenient to clean the metal debris on the surface of the equipment after the processing is completed.
