Abstract
The utility model discloses a precise sleeve type spindle which comprises a spindle body and a spindle sleeve outside the spindle body. A spindle seat is arranged at the tail of the spindle body, a spindle cap is arranged at the head of the spindle, the spindle sleeve is connected with the spindle body through a bearing, a driving wheel is arranged between the spindle seat outside the spindle body and the spindle sleeve, and a connecting flange is arranged on the spindle seat. The precise sleeve type spindle is directly fixedly connected with a mounting base body by the integrated spindle body, thereby being high in rigidity and better in stability. Besides, the spindle body is fixed by the high-load bearing, can be dragged by a servo motor directly and can be driven by a synchronous pulley or gear, so that high rotating speed is guaranteed while acceleration and deceleration can be adjusted, and further milling accuracy and machining efficiency are improved.
Description
Technical field
The utility model belongs to field of machining, is specifically related to a kind of accurate sleeve-type main shaft.
Background technology
Milling machine is that cutter is direct and main shaft is fixed, provide cutting force by the rotation of main shaft band cutter, so, main shaft spacing very important, general milling machine is to adopt gear or belt wheel to be rigidly connected with main shaft, can produce certain gap at belt wheel or gear and main shaft junction like this, and main shaft has throw slightly when rotation, milling is produced unfavorable factor, affect the precision of the processing of workpiece.And the transmission mechanism operated by rotary motion is at spindle nose, uses V belt to connect, and the speed of mainshaft is low, and moment of torsion is little, and it is rough to add the man-hour plane, and cutting speed is slow, and cutting depth slightly belt creep may well occur, the main shaft stuck phenomenon, and fault rate is high.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of accurate sleeve-type main shaft of accurate milling workpiece to be provided.
Technical scheme: accurate sleeve-type main shaft described in the utility model, its objective is such realization: a kind of accurate sleeve-type main shaft, comprise the axle sleeve that main shaft and main shaft are outer, main shaft tail also is provided with axle bed, spindle nose also is provided with shaft-cup, be provided with bearing between described axle sleeve and the main shaft and be connected, main shaft outside axle bed and axle sleeve centre position also are provided with drive, and described axle bed is provided with adpting flange.
Described bearing is located at two ends and the centre position of axle sleeve, and shaft-cup and main shaft junction also are provided with bearing.
Described drive is belt wheel or gear.
Described bearing is the high load capacity bearing, and bearing closely is connected with main shaft.
Beneficial effect: accurate sleeve-type main shaft described in the utility model adopts integral one-piece mainshaft directly to be fixedly connected with the installation matrix, good rigidly, and better stability is arranged, main shaft adopts the high load capacity bearing to fix, can directly drag by servomotor, also can use synchronous pulley or gear drive, both guarantee that high rotating speed also can regulate acceleration and deceleration, thereby improved precision and the working (machining) efficiency of milling.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
Referring to accurate sleeve-type main shaft shown in Figure 1, comprise main shaft 1, the afterbody of main shaft 1 is fixing axle bed 2, and main shaft 1 outside is provided with axle sleeve 3, axle sleeve 3 is fixed at flange 5 places with installation matrix 4, axle sleeve 3 fronts also are provided with shaft-cup 6, and main shaft 1 is fixing with axle sleeve 3 and shaft-cup 6 by bearing 7, is equipped with bearing 7 in two ends and the centre position of axle sleeve 3, Selection of Bearings high load capacity bearing, and closely be connected with main shaft 1, also be provided with transmission mechanism 8 between axle bed 2 and the axle sleeve 3, the diagram transmission mechanism is belt wheel.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
