Automatic ejector pin spiral groove grinding device

The invention relates to the field of hardware dies, in particular to an automatic ejector pin spiral groove grinding device. The automatic ejector pin spiral groove grinding device mainly comprises acutting wheel and an installing base arranged in front of the cutting wheel. The installing base and the cutting wheel deflect by a certain angle to be arranged. The installing base comprises a leftclamping part, a right clamping part and an upper clamping part jointly clamping an ejector pin, and the surface of the tail of the ejector pin is right opposite to the bottom of the cutting wheel forcutting. The automatic ejector pin spiral groove grinding device is low in cost, an ejector pin spiral groove can be machined on an ordinary grinding machine, positioning is accurate and stable, clamping is rapid, person hand slight holding is not needed in the machining process, automation is completely achieved, the production efficiency is greatly improved, and the time and labor cost is saved. 本发明涉及五金模具领域，具体涉及一种顶针螺旋槽自动
