Summary of the invention

The purpose of this utility model seeks to solve that existing float grease seal grinding machine structure is complicated, grinding efficiency is low, It is operationally time-consuming and laborious, and the problem of be difficult to ensure product quality, a kind of car coat type float grease seal grinder is provided thus.

The concrete scheme of the utility model is: a kind of car coat type float grease seal grinder, has rack, it is characterized in that: institute It states equipped with horizontally disposed grinding rotary table on the upside of rack, downside is equipped with motor, the central axis on motor and grinding rotary table It constitutes and is drivingly connected；Several stop collars are placed on grinding rotary table；It is equipped on the rack and is circumferentially arranged in grinding rotary table At least two vertical supports in outside, each vertical support are respectively connected with one end of a horizontal cross bar, each horizontal horizontal The other end of bar stretches to grinding rotary table, and is connected with snap ring and connects, and the charging basket for containing lubricant is installed on snap ring；? The both ends of horizontal cross bar are each fitted with deck, and each deck is fastenedly connected the upper end of a sunpender, and the lower end of sunpender is equipped with water The bearing that plain cloth is set；The outer wall of the stop collar is equipped with the concave groove of annular, two bearings fastened on each horizontal cross bar Correspondence is in be in rolling contact to connect with the concave groove on a stop collar.

Rack described in the utility model is equipped with rhone, and grinding rotary table is placed in rhone；In the downside of rack Catch basin is placed on face, rhone connects catch basin by drainpipe.

It is equipped on the rack described in the utility model and is circumferentially uniformly grinding four vertical supports on the outside of rotary table.

The utility model structure is simple, ingenious in design, at work, work of each stop collar in the centrifugal force of grinding rotary table It is installed under between every group of two horizontal bearings, the float grease seal of different model can be respectively placed in as needed Horizontal grinding is carried out in different stop collars, not only grinding efficiency is high, but also is easy to implement to the float grease seal of different model Sort operation, and ensure product quality.
