Summary of the invention
Therefore, the purpose of the utility model provides a kind of high-speed main spindle, and this main shaft has high rotating speed, can carry out High-speed machining, can not produce thermal deformation, can work long hours and does not influence the precision of processing.
Another purpose of the utility model provides a kind of high-speed main spindle, and this main axle structure is reliable and stable, is convenient to realize, can be widely used in the grinding machine separately, milling machine, drilling machine of existing machinery processing.
For achieving the above object, the utility model is to realize like this.
A kind of high-speed main spindle, its outside is a housing, and inside is main shaft, and rear-end of spindle is connected with oil hydraulic cylinder; Front end is connected with cutter, it is characterized in that said main shaft is a hollow structure, is socketed with pull bar in it; The pull bar front end is connected to guide ring, and the guide ring front end is fixed with claw, claw fixed cutting tool or milling head; And the main shaft set inside has cooling oil circuit and air blowing pipeline.Through the cooling oil circuit main shaft is cooled off, can cool off main shaft in time, apace, reduce the operating temperature of main shaft, the peripheral thermal deformation of the main shaft of avoiding the main shaft long-term work to cause helps ensureing the precision and the reliability of processing; Avoid pollutant or cutting fluid to get into main shaft through the air blowing pipeline, guarantee the work of main shaft.
Outside the said main shaft, be arranged with spiral helicine cooler, so that main shaft is cooled off.
On the said main shaft, be socketed with axle, the rear end of axle has bearing, to strengthen the rock-steady structure of axle and main shaft.
Said axle, its outside also is fixed with chip and coil groups, and chip and coil groups are connected on the high-speed electric expreess locomotive, with under the drive of high-speed electric expreess locomotive, main shaft are run up.
Said high-speed main spindle, the rear end of its housing is provided with taper hole, and to blow, the housing front end has venthole, forms the air blowing pipeline between taper hole and the venthole, and gas forms air curtain in the air blowing pipeline, avoid pollutant or cutting fluid to get into main shaft.
Said high-speed main spindle, the rear end of its housing are respectively arranged with cooling oilhole inlet and cooling-oil outlet, and cooling oilhole inlet and cooling-oil outlet are connected on the cooler.Cold oil is input in the cooler after entering in the main shaft, and after fully cooling off to main shaft, again from cooling-oil outlet output, cooling oilhole and cooling-oil outlet and cooler form the cooling oil circuit, can guarantee the abundant cooling of main shaft.
The utility model adopts above-mentioned main axle structure; Can under the situation that main shaft runs up, guarantee main shaft is cooled off effectively; Avoid the main shaft periphery thermal deformation to occur, the precision that makes main shaft can keep processing works long hours, thereby working (machining) efficiency and reliability are provided.
And the utility model stable and reliable structure realizes easily, can be widely used in existing grinding machine, milling machine (carving mills machine), the drilling machine.
Description of drawings
The structural representation that Fig. 1 practices for the utility model.
Fig. 2 is the side view of A-A part among Fig. 1.
The specific embodiment
Shown in accompanying drawing, the practical implementation of the utility model is elaborated.
