Description

Grinding machine device for processing rotor shaft

Technical Field

The utility model relates to a grinding machine equipment field, in particular to a grinding machine device for processing rotor shaft.

Background

The rotor used for the vane pump, the automobile direction booster pump and the automobile air-conditioning compressor is composed of a rotor shaft, the roughness of the end face of the rotor shaft not only influences the rotating stability of the assembled rotor, but also has high noise, so that the end face of the rotor shaft needs to be ground after the rotor is machined and formed. The end face of a rotor shaft is ground by a grinding wheel in the conventional grinding machine, but the conventional rotor shaft has the following problems in the machining process:

1. burrs are easy to remain on the surface of the workpiece, and the grinding precision is low.

2. The grinding wheel is in full contact with the end face of the rotor shaft, so that the grinding end face is not convenient to be cooled by coolant and lubricant, and high temperature generated during grinding is caused, and the surface of a workpiece is burnt at high temperature; but also leads the sand on the surface of the grinding wheel to fall off, causes the quick failure of the grinding wheel, needs to continuously correct the grinding wheel and is inconvenient for batch processing.

Disclosure of Invention

The utility model aims at providing an improve the grinding machine device that is used for processing rotor shaft of rotor shaft end face precision and mass production to the not enough of prior art.

The technical scheme of the utility model is that:

the utility model provides a grinding machine device for processing rotor shaft, includes the workstation, be equipped with the head top and the tail top that are used for pressing from both sides tight location work piece on the workstation, and be used for polishing the emery wheel of work piece, its characterized in that: the end face of the grinding wheel is provided with a protruding grinding ring for grinding a workpiece, and the grinding ring is arranged along the circular ring of the grinding wheel.

Further, the width of the grinding ring is 1-3 mm, and the thickness of the grinding ring is 1-3 mm.

Further, the width of the grinding ring is 2 mm.

Furthermore, the tail center is a half-cut center, and the distance from the tip of the half-cut center to the cut surface is smaller than the radius of the central hole of the rotor shaft to be processed by 0.5-1 mm.

Further, the axis of the tail tip is lower than the axis of the head tip.

Further, the axis of the tail tip is 0.5-1 mm lower than the axis of the head tip.

Adopt above-mentioned technical scheme to have following beneficial effect:

the utility model has the advantages of simple structure, set up the convex ring of polishing that is used for polishing the work piece through the terminal surface at the emery wheel, reduce and wait to process the area of contact of rotor shaft terminal surface through the ring of polishing, the coolant liquid and the emollient of not only being convenient for cools off work piece and emery wheel fast, have avoided the emery wheel to become invalid fast, have realized rotor shaft processing in batches. And the grinding wheel dust generated during grinding of the grinding wheel can be removed in time, so that the machining precision of the rear end face of the rotor is improved. The event the utility model provides high rotor axle end face precision, rotor axle end face and axial direction line's straightness that hangs down make the rotor axle assemble into the rotation behind the rotor more steady, and dry sound is showing and is reducing.

The following description is further described in conjunction with the accompanying drawings and the detailed description.

FIG. 2 is a schematic structural view of the grinding wheel of the present invention;

fig. 3 is a sectional view taken along line a-a of fig. 2.

In the attached drawing, 1 is a head tip, 2 is a tail tip, 3 is a grinding wheel, 4 is a grinding ring, and 5 is a rotor shaft to be processed.

Detailed Description

Specific example 1:

referring to fig. 1 to 3, a grinding machine device for machining a rotor shaft includes a table, on which a head center 1 and a tail center 2 for clamping and positioning a workpiece, and a grinding wheel 3 for grinding the workpiece are provided; the head center 1 is installed on a workbench through a head frame, the tail center 2 is installed on the workbench through a tail seat, the tail center 2 adopts a half-cut center, the distance from the tip of the half-cut center to the cut surface is smaller than the radius of a central hole of a rotor shaft to be processed by 0.5-1 mm, and in the specific embodiment: the distance from the tip of the half-cut tip to the cut surface is smaller than the radius of a central hole of the rotor shaft to be processed by 0.5mm, the structure enables the grinding wheel to polish the end face of the rotor shaft as comprehensively as possible, and the precision of the end face of the rotor shaft is improved. Possibly, the axis of the tail center 2 is lower than the axis of the head center 1, and the axis of the tail center 2 is 0.5-1 mm lower than the axis of the head center 1. In this particular embodiment: the axis of the tail center 2 is 0.8mm lower than that of the head center. The axis of the tail center is lower than that of the head center, so that the grinding wheel 3 is more involved in grinding when being contacted with the end face of the rotor shaft 5 to be processed, and less involved in grinding when being separated from the end face of the rotor shaft to be processed.

The end face of the grinding wheel 3 is provided with a protruding grinding ring 4 used for grinding a workpiece, the grinding ring 4 is arranged along the circular ring of the grinding wheel 3, the width r of the grinding ring 4 is smaller than the radius of a rotor shaft to be machined, the width r of the grinding ring 4 is 1-3 mm, and the thickness h of the grinding ring 4 is 1-3 mm. In this particular embodiment: the width r of the polishing ring 4 is 2mm, and the thickness h of the polishing ring 4 is 2 mm. The grinding ring 4 and the end face of the rotor shaft 5 to be processed are in contact grinding, the contact area between the grinding wheel and the end face of the rotor shaft to be processed is reduced, the grinding wheel and the rotor shaft to be processed are cooled by the coolant and the lubricant, and meanwhile, grinding wheel ash generated in the grinding process is timely cleaned, so that the roughness of the end face of the rotor shaft to be processed is reduced.

The utility model is suitable for a realize the end face grinding on ordinary cylindrical grinder, can realize the clamping of product, each partial position grinding is once accomplished.
