Feeding protection mechanism for horizontal thread rolling machine

Abstract

The invention discloses a feeding protection mechanism for a horizontal thread rolling machine. The feeding protection mechanism for the horizontal thread rolling machine comprises a support, guide pillars, a movable plate, a star handle, springs and a pressing block, wherein the support is 'L'-shaped; a vertical side of the support is fixed to a thread rolling machine body; cylindrical through holes in the vertical direction are formed in a horizontal side of the support; the upper ends of the guide pillars penetrate through the cylindrical through holes of the support and are connected with the movable plate; the lower ends of the guide pillars are connected with the pressing block; one spring sleeves the outer surface of each guide pillar; the star handle is mounted on the movable plate; and a round hole is formed in the middle of the pressing block. A thread rolling station of an existing thread rolling machine does not have a feeding protection mechanism, and a worker needs to press a workpiece with hands in a thread rolling process, and is injured easily. After the feeding protection mechanism disclosed by the invention is additionally arranged on the thread rolling machine, the following effects can be achieved: firstly, jumping of the workpiece is prevented during thread rolling of the workpiece, particularly in a few seconds at the beginning of thread rolling; and secondly, the possible circumstance that the hands of the worker are pinched and the worker is injured is avoided. Feeding protection is realized by a simple connection assembly and an elastic fixing assembly, and the structure is quite simple.

Description

technical field [0001] The invention relates to a mechanical processing equipment, in particular to a horizontal thread rolling machine. Background technique [0002] At present, in the thread processing of aviation fasteners and parts, in order to improve the fatigue strength of the thread, most of them adopt thread rolling processing, and the commonly used equipment is horizontal thread rolling machine. However, on the horizontal thread rolling machine, there is currently no safety protection mechanism for the workpiece clamping function. When the operator operates the thread rolling machine, the workpiece needs to be placed on the thread rolling machine support for positioning. The wire machine support automatically falls off, and the thread rolling process cannot be completed, so the operator needs to support the workpiece with his hands. In the process of thread rolling, because the thread rolling wheel drives the workpiece to rotate at high speed, it often happens tha...

Problems solved by technology

However, the structure of the device is relatively complicated, and it cannot fundamentally solve the safety problem of workers supporting the workpiece with their hands for thread rolling processing. It can only solve the timely shutdown after an accident, which belongs to post-processing, and has no error-proof function.

And this device does not solve the protection problem of charging
