Description
Technical field
The utility model relates to line mouth inner hole grinding technique fields, and in particular to a kind of tension guarantor of line mouth hole abrading machine
Hold grinding auxiliary body.
Background technique
The interior hole machined of line mouth tubing (hereinafter referred to as " line mouth ") is the important procedure of line mouth production processing, this process
Need to guarantee diameter, circularity and the finish of line mouth inner hole.Existing line mouth processing belongs to labour intensive shape industry, entire industry
Fall behind relatively all in production equipment, the state that the degree of automation is low.Therefore, this procedure manufacturing process at present in industry is equal
For handwork or semi-mechanization operation.
Wherein, handwork is exactly to use a rope or non-metal wire, is passed through the inner hole of line mouth.In rope when processing
Or abrasive material is stained on line, rope is then held respectively or the both ends of line are back and forth pullled.The method extremely falls behind, not only production efficiency
It is low, and the circularity of line mouth inner hole not can guarantee.
There are two types of semi-mechanization operations, one is line mouth to be clipped in a mechanism, can be driven by a motor line by mechanism
Mouth rotation, while still line mouth inner hole is passed through with a rope or non-metal wire.When processing, it is stained on rope or line
Abrasive material, then holds rope respectively or the both ends of line are back and forth pullled, isochrone mouth high speed rotation.The production efficiency of the method is purer
It is significantly improved by hand, but the processing quality improvement of the diameter for line mouth inner hole, circularity and finish is unobvious.
Another semi-mechanization means are to select a steel wire by the line mouth internal diameter of preprocessing, line mouth inner hole are passed through, in quilt
Mill line wheel and grinding auxiliary wheel are installed in the left and right sides of processing line mouth respectively, and steel wire is wound on mill line wheel and grinding auxiliary wheel
Above and between mill line wheel and grinding auxiliary wheel form closed loop.When grinding, it is stained with abrasive material on steel wire, is gone round and round a millstone by worker's left-right rotary
Wire reels drive steel wire for linear motion, when steel wire passes through line mouth inner hole, abrasive material are driven to grind inner hole.The method
Advantage is preferably guarantee diameter, circularity and the finish of line mouth inner hole；The shortcomings that the method, is also obvious simultaneously,
Be first worker labor intensity it is larger, followed by steel wire linear motion the amount of feeding be not easily controlled, the excessive abrasive material of the amount of feeding
