The utility model provides a dustproof structure of a chuck, which includes a chuck housing and a closed structure. A chuck shell has an open installation cavity in one side of the chuck shell, and the other side of the chuck housing is provided with a feeding channel through the installation cavity. The installation cavity is equipped with a claw group around the feeding channel, and the closed structure is used to close the installation. The cavity is provided with an air inlet, and the air inlet is communicated with the closed cavity. The utility model can form a closed cavity in the installation cavity through a closed structure. At the same time, a small positive pressure is formed in the installation cavity of the claw assembly through the inlet air inlet. In other words, the internal pressure of the clamping chamber of the claw assembly is higher than the ambient atmospheric pressure to prevent the mass entry of the smoke and dust produced during the cutting and prevents the claw and the claw from the claw. Too much smoke and dust are accumulated on the matching surface of the slider, at the same time, once the inner cavity of the chuck has been prevented from accumulating too much dust, and the phenomenon of chuck card death is avoided, and the service life of the chuck is increased.

一种卡盘防尘结构
本技术涉及激光切管机
,主要涉及一种卡盘防尘结构。
技术介绍
目前,市场上的激光切管机在切割时会产生大量的烟尘,烟尘会进入到卡盘中,但是这些切管机的卡盘的封闭性较差,使得卡爪与与滑块因为其配合面上积聚了过多烟尘而导致卡爪与滑块之间的磨损较快,降低了卡盘的使用寿命,严重时会导致卡爪与滑块之间出现卡死现象;而且,卡盘内腔一旦积累了过多的粉尘,便会和润滑油混合在一起形成油灰泥状,影响了卡盘的工作,也降低了卡盘的使用寿命。
技术实现思路
本技术的目的在于克服现有技术的不足,提供一种可防止卡爪与滑块之间出现卡死现象,同时可防止卡盘内腔积尘过多的想象的卡盘防尘结构。为了解决上述技术问题,本技术采用以下技术方案:一种卡盘防尘结构,其包括卡盘壳体和封闭结构,所述卡盘壳体内设有一侧敞口的安装腔,所述卡盘壳体的另一侧设有贯穿所述安装腔的送料通道,所述安装腔内围绕所述送料通道外周设有卡爪组件,所述封闭结构用于封闭所述安装腔,使其形成封闭腔体,所述卡盘壳体上设有进风口,所述进风口与所述封闭腔体连通。与现有技术相比,本技术提供的卡盘防尘结构,其通过封闭结构使得安装腔形成了一个封闭的腔体,同时通过进风口往卡爪组件安装腔里面吹风,形成了一个微正压,即卡爪组件安装腔的内气压高于周围大气压,阻止切割时所产生的烟尘的大量进入,吹进去的风从卡爪组件与卡盘壳体的连接间隙之间排出,防止了卡爪与与滑块的配合面上积聚过多的烟尘,同时防止了卡盘内腔一旦积累了过多的粉尘,避免了出现卡盘卡死的现象,增加了卡盘的使用寿命。优选的,所述封闭结构包括第一盖板和第二盖板,所述第一盖板为动态盖板,其与 ...
