The utility model content
The purpose of this utility model is in order to address the above problem, a kind of deep Hole electricity main shaft to be provided, coming the deep hole part of working depth more than 200mm.
The technical solution of the utility model is: a kind of deep Hole electricity main shaft, contain grinding spindle and prolong mechanism and electric main shaft, this grinding spindle extending structure is installed in electric front-end of spindle, this grinding spindle prolongs mechanism and contains grinding extension bar, axle sleeve, belt shaft, connecting axle, described axle sleeve is a hollow elongated tube, end at axle sleeve is provided with the connection disk body, and the support of this connection disk body and electric main shaft links together; Described connecting axle, belt shaft are installed in described hollow elongated tube inside, and near terminal pad one end, belt shaft is at the other end in hollow pipe for connecting axle; Connect by shaft coupling between described connecting axle and the belt shaft, described connecting axle also is connected with shaft coupling near an end that connects disk body, this shaft coupling connects electric main shaft and connecting axle, and described belt shaft stretches out on the termination of hollow pipe described grinding extension bar is installed.
Described connecting axle is installed in axle sleeve inside by the axle axle, and described belt shaft also is to be installed in axle sleeve inside by bearing.
Be provided with hermetically-sealed construction between the end of described belt shaft and axle sleeve hollow pipe, the sealing structure contains sealing ring, the preceding seal cover that is contained in the hollow pipe termination and is installed in two inner seal rings that interlock mutually in the hollow pipe.
The installation bearing of described belt shaft has two groups, be set in the two ends of belt shaft, be provided with the elasticity pre-pressing structure between two groups of bearings, this elasticity pre-pressing structure contains spacer, adjustment packing ring, the spring base that is sleeved between belt shaft and the hollow pipe, spring, spring pad; Described two groups of bearings all contain two bearings and are supported on inside and outside dottle pin between the bearing; The inner end of described belt shaft is provided with the adjustment nut, is pressed on the bearing in advance.
Described connection disk body is fixedly connected on the support termination of electric main shaft by fastening bolt.
The beneficial effects of the utility model
This deep Hole electricity main shaft can make the working depth of grinding electricity main shaft prolong by installing the grinding spindle extending structure additional, makes grinding electricity main shaft can process 600mm with interior deep hole.。
