Abstract
A high-speed plain spindle structure belongs to machine tool spindles. The utility model is characterized in that a spindle sleeve (2) is mounted on the outer ring of a front spindle bearing (4) and a rear spindle bearing (7), a front flange plate (6) is mounted at the front end of the spindle sleeve (2), a rear flange plate (9) is mounted at the rear end of the spindle sleeve (2), and powerful assembly glue (14) is arranged between a spindle box (1) and the spindle sleeve (2). By separating the spindle and a box body, the accuracy of the spindle can be adjusted independently, and the powerful assembly glue is poured between the spindle box and the spindle sleeve. Therefore, the utility model has the advantages of high transmission accuracy, good power torque characteristics, high rotational speed, low noise, steady transmission and compact structure, and is less susceptible to be affected by temperature.
Description
Technical field
The utility model belongs to machine tool chief axis, relates to a kind of High Speed Light main axle structure.
Background technology
Current, especially multifunctional high speed numerically controlled lathe of many lathes is arranged, they are very high to the required precision of main spindle box, most of main spindle boxes are installed the brearing bores place to be needed high precision apparatus to process to guarantee precision, need several equipment just can finish the processing of main shaft casing like this, increase cost, waste time and energy, also be unfavorable for energy savings
Goal of the invention
The purpose of this utility model just provides a kind of precision machined High Speed Light main axle structure of main spindle box that do not need.
The solution that realizes the utility model purpose is to comprise main spindle box 1, main shaft 3, forward spindle bearing 4, back main shaft bearing 7, preceding locking nut 5, back locking nut 8, particularly rack sleeve 2 is installed in the outer ring of forward spindle bearing 4 and back main shaft bearing 7, the front end of rack sleeve 2 is equipped with forward flange dish 6, and the rear end is equipped with rear stub 9, is powerful assembly adhesive 14 between main spindle box 1 and rack sleeve 2.
On main spindle box 1, be provided with gum-injecting port 15.
The utility model has the advantages that and adopt main shaft to separate with casing, main shaft can be adjusted precision separately, with the every precision index of main shaft adjust up to standard after, between powerful assembly adhesive injection main spindle box and rack sleeve, have the transmission accuracy height, the power torque characteristics is good, the rotating speed height, noise is low, stable drive, compact conformation, and temperature do not had advantages such as significant change.Can be installed in simply and easily in the coarse casing endoporus of any processing, can save process greatly like this, increase work efficiency, economize labor time.Main spindle box is optimized assembly structure.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-main shaft casing, 2-rack sleeve, 3-main shaft, locking nut before the 4-forward spindle bearing, 5-, 6-forward flange dish, main shaft bearing behind the 7-, locking nut behind the 8-, 9-rear stub, adjust ring flange before the 10-, adjust screw before the 11-, adjust ring flange behind the 12-, adjust screw behind the 13-, the powerful assembly adhesive of 14-, the 15-gum-injecting port.
The specific embodiment
Between the front end of main shaft 3 and rack sleeve 2, forward spindle bearing 4 is installed, preceding locking nut 5; Back main shaft bearing 7 is installed between the rear end of main shaft 3 and rack sleeve 2, back locking nut 8, front end at main shaft 3 and rack sleeve 2 is equipped with forward flange dish 6, rear end at main shaft 3 and rack sleeve 2 is equipped with rear stub 9, forward flange dish 6 is enclosed within on the main shaft 3 with rear stub 9, is fixed on the rack sleeve 2 by screw.After installing, main shaft is carried out accuracy detection.Earlier the adjustment of main shaft precision is finished, rack sleeve 2 assemblies pack into main shaft casing 1 to the precalculated position then, adjust ring flange 10, preceding adjustment screw 11, back adjustment ring flange 12 and back before being equipped with on the casing 1 and adjust screw 13, rack sleeve 2 assemblies and main shaft 3 are carried out the precision adjustment, behind to be adjusted the finishing, inject powerful assembly adhesive 14 from casing 1 top gum-injecting port 15, parch and adjust that ring flange 10, preceding adjustment screw 11, back are adjusted ring flange 12, screw 13 is adjusted in the back before can taking off etc. powerful assembly adhesive 14, this moment, main spindle box installed.
Claims (2)
1. High Speed Light main axle structure, comprise main spindle box (1), main shaft (3), forward spindle bearing (4), back main shaft bearing (7), preceding locking nut (5), back locking nut (8) is characterized in that in the outer ring of forward spindle bearing (4) and back main shaft bearing (7) rack sleeve (2) being installed, and the front end of rack sleeve (2) is equipped with forward flange dish (6), the rear end is equipped with rear stub (9), is powerful assembly adhesive (14) between main spindle box (1) and rack sleeve (2).
