Abstract
The utility model discloses an adjustable workpiece spindle, belonging to the field of grinder component devices. The existing workpiece box and grinding wheel box have a defect of inconvenient assembly. The adjustable workpiece spindle disclosed by the utility model comprises a spindle and a sleeve, wherein the sleeve is fixedly mounted in a box body of a spindle box by a screw; a through hole is formed in the sleeve; the spindle is supported and mounted in the through hole of the sleeve through a bearing group; the centre line of the outer ring of the sleeve is not on the same straight line with the centre line of the spindle; the two ends of the sleeve are fixed by a gland. According to the adjustable workpiece spindle, the sleeve on the spindle box is adjusted, and the grinding wheel box does not need to be dismantled, thereby simplifying the assembly process of a grinder and improving the assembly efficiency of the grinder.
Description
Technical field
The utility model belongs to grinding machine components device field, and is especially relevant with the work spindle on a kind of workpiece box.
Background technology
In the process of assembling numerical control bearing grinding machine, the height of the center line of the main shaft on workpiece spindle box need to remain in certain size range with the height of the center line of emery wheel case main shaft.Existing mounting technology is to realize by set up adjusting pad bottom the emery wheel case, at first the emery wheel case is installed on bed piece, then calculate difference in height between the spindle centerline of emery wheel case spindle centerline and workpiece spindle box with height gauge, then pull down the emery wheel case adjusting pad of suitable dimension is installed to emery wheel case bottom, thereby reach the dimensional requirement of the spindle centerline of emery wheel case spindle centerline and workpiece spindle box, the process of assembling extremely bothers like this, greatly reduces the efficiency of assembling of lathe.
The utility model content
The purpose of this utility model overcomes the defective of the assembling inconvenience of existing workpiece box and the existence of emery wheel case, and a kind of convenient adjustable work spindle of installing is provided.
For this reason, the utility model is by the following technical solutions: a kind of adjustable work spindle, comprise main shaft, it is characterized in that, also comprise sleeve, sleeve is fixedly installed in the axis hole of spindle box body by screw, sleeve is provided with through hole, main shaft supports by bearing group in the through hole that is installed on sleeve, and the center line of described sleeve outer ring and the center line of main shaft be not on the same straight line, and the two ends of sleeve are fixed by gland.When needs are regulated the center line height of work spindle, unclamp the screw on sleeve, pass through regulating sleeve, this moment, the center line height of work spindle changed along with the rotation of sleeve, after being adjusted to correct position, sleeve is fixed and can be completed by screw, improved efficiency of assembling.
As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.
Radially locking by the locking double-screw bolt of described sleeve lateral wall.
Use the utility model can reach following beneficial effect: the utility model passes through to regulate the sleeve on main spindle box, thereby does not need the emery wheel case is pulled down, and has simplified the program of grinding machine assembling, has improved the efficiency of assembling of grinding machine.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises main shaft 3 and sleeve 2, sleeve 2 is fixedly installed in the axis hole of spindle box body 1 by screw, sleeve 2 is provided with through hole, main shaft 3 supports in the through hole that is installed on sleeve 2 by bearing group, the center line 6 of described sleeve outer ring and the center line 7 of main shaft be not on the same straight line, and the two ends of sleeve 2 are fixing by gland 5, and the locking double-screw bolt 4 that radially passes through of sleeve lateral wall locks.When needs are regulated center line 7 height of main shaft, unclamp the screw on sleeve 2, by regulating sleeve 2, this moment, center line 7 height of main shaft changed along with the rotation of sleeve 2, after being adjusted to correct position, sleeve 2 is fixed and can be completed by screw, improved efficiency of assembling.
