Abstract
The utility model provides a device for boring an inner hole of a spindle, which comprises a machine tool chuck, a tailstock and a carriage. One end of a boring rod is clamped by the machine tool chuck, the other end of the boring rod is abutted by the tailstock, a boring tool is fixedly arranged on the boring rod, a cushion block is fixedly arranged on the carriage, a flat plate is arranged on the cushion block, a support seat is arranged on the flat plate, a slip holder is arranged on the support seat, a workpiece to be machined is fixed onto the slip holder by the aid of a pressing plate, a limit block is arranged at one end of the flat plate, a travel switch is fixedly arranged on a machine tool, and a positioning pin is arranged on one side of the support seat. The device solves the problem of coaxiality of the machined inner hole and an outer circle of the spindle, meets the requirement of the spindle on dynamic balance, and is convenient in clamping, fast in boring speed, time-saving and high in quality, the workpiece can be bored by means of one-step clamping, machining efficiency is improved, and cost is reduced.
Description
Technical field
The utility model belongs to mechanical field, specifically a kind of main shaft endoporus boring processing device.
Background technology
Conventional main shaft method for machining bore is directly to drill through from an end with special-purpose deep hole drilling machine; Because the endoporus draw ratio of machine tool chief axis is all very big; Belong to elongated orifices; So adopt the endoporus that this processing mode processes and the axiality of main shaft cylindrical to guarantee, when main shaft rotates at a high speed, can't satisfy dynamically balanced requirement.At present the processing method of high-speed main spindle endoporus is first roughing, stays the 1-2mm surplus, again with general car right boring to the size that requires, owing to the hole is longer; Need with the lengthening knife bar from two ends boring, clamping at twice, efficient is lower; And boring place is connect cutter, and its dynamic balancing does not reach requirement, is prone to waste product.
Summary of the invention
The utility model provides a kind of main shaft endoporus boring processing device, has solved the shortcoming that processing high-speed main spindle endoporus efficient is low in the background technology, percent defective is high.
The technical scheme of the utility model is achieved in that a kind of main shaft endoporus boring processing device, comprises machine chuck, tailstock, planker, and machine chuck clamps boring bar one end; The boring bar other end holds out against with tailstock; Fixedly be equipped with boring cutter on the boring bar, fixedly be equipped with cushion block on the planker, be equipped with flat board on the cushion block; Be equipped with supporting seat on the flat board, be equipped with a watt seat on the supporting seat;
Need the workpiece of processing to be fixed on watt seat with pressing plate;
A dull and stereotyped end is equipped with limited block, fixedly is equipped with travel switch on the lathe;
Supporting seat one side is equipped with alignment pin.
The beneficial effect of the utility model is: the utility model has solved the axiality problem of machining spindle endoporus and cylindrical, reaches the main shaft requirement for dynamic balance, convenient mounting and clamping; No. one time clamping just can be accomplished, and boring speed is fast, saves time; Quality is high, has improved working (machining) efficiency, has reduced cost.
