CN2827637Y - Formed knife disc dressing device for milling of bevel gear - Google Patents

Abstract

The utility model relates to a formed knife disc dressing device for milling of a bevel gear, which belongs to the mechanical processing class. The utility model comprises a bed body, a box for a main shaft, the main shaft, a grinding head, a seat for the grinding head and a knife disc for milling. The utility model is characterized in that the seat for the grinding head is arranged on a transverse guide rail which is arranged on a longitudinal guide rail; a dressing knife is fixed on the bed body on one side of the grinding head, and the other side is provided with the knife disc for milling; the transverse guide rail and the longitudinal guide rail are controlled by a digital control motor and are matched with each other to make the grinding head form a required shape under the dressing of the dressing knife, and then, the movement of the dressed grinding head is controlled to carry out dressing to the shape of a section of the knife disc for milling. The utility model has the advantages of reasonable structure and convenient adjustment.

Description

Bevel gear mill teeth shaping cutterhead correction of the flank shape device

Technical field

The utility model belongs to the machining class.

Background technology

In half generating method machining of bevel gears process, when cutting out the bull wheel flank of tooth with forming process, need earlier the mill teeth cutterhead to be repaired, promptly must adjust the shape of cutter according to the requirement of contact zone on short transverse, because it is bigger to adjust difficulty, the adjustment effect is not ideal enough, often influences the machining accuracy of gear.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, and a kind of bevel gear mill teeth shaping cutterhead correction of the flank shape device rational in infrastructure, that can repair the shape of mill teeth cutterhead easily is provided.

The technical solution of the utility model is as follows:

A kind of bevel gear mill teeth shaping cutterhead correction of the flank shape device, comprise lathe bed, main spindle box, main shaft, bistrique, bistrique seat, mill teeth cutterhead, the mill teeth cutterhead is contained on the main shaft, main spindle box is fixed on the lathe bed, it is characterized in that: the bistrique seat is contained on the cross slide way, cross slide way is contained on the longitudinal rail, on the lathe bed of a side of bistrique, be fixed with finishing knife, the mill teeth cutterhead is housed on the main shaft of bistrique opposite side, main shaft, bistrique seat axis at grade, cross slide way and longitudinal rail are controlled by numerical-control motor.

When the utility model uses, bistrique is adjusted the position by cross slide way and longitudinal rail under the control of numerical-control motor, according to the shape of the required cutterhead of mill teeth, repaired the shape of bistrique earlier by finishing knife, again bistrique is moved to the mill teeth cutterhead, make the correction of the flank shape of mill teeth cutterhead to required shape.

The utility model is adjusted the position of bistrique easily by the motion of numerical-control motor control bistrique in cross slide way, longitudinal rail, adopts trimmed bistrique to repair the mill teeth cutterhead, and is rational in infrastructure, easy to operate.

The drawing explanation

Fig. 1 is the utility model structural representation.

The specific embodiment

As shown in Figure 1, a kind of bevel gear mill teeth shaping cutterhead correction of the flank shape device, comprise lathe bed 1, main spindle box 2, main shaft 3, bistrique 5, bistrique seat 6, mill teeth cutterhead 4, mill teeth cutterhead 4 is contained on the main shaft 3, main spindle box 2 is fixed on the lathe bed 1, it is characterized in that: bistrique seat 6 is contained on the cross slide way 7, cross slide way 7 is contained on the longitudinal rail 8, on the lathe bed of a side of bistrique 5, be fixed with finishing knife 9, on the main shaft 3 of bistrique opposite side mill teeth cutterhead 4 is housed, main shaft 3, bistrique seat 6 axis at grade, cross slide way 7 and longitudinal rail 8 are respectively by numerical-control motor 10,11 controls.

Finishing knife 9 of the present utility model is the diamond grinding wheel dressing cutter.

Cross slide way 7 of the present utility model and longitudinal rail 8 are by the numerical-control motor controlled motion, both cooperations make bistrique form required shape under the finishing of diamond grinding wheel dressing cutter 9, then, the motion of the bistrique 5 after the control correction of the flank shape is repaired the cross sectional shape of mill teeth cutterhead 4.

Claims (2)

1, a kind of bevel gear mill teeth shaping cutterhead correction of the flank shape device, comprise lathe bed (1), main spindle box (2), main shaft (3), bistrique (5), bistrique seat (6), mill teeth cutterhead (4), mill teeth cutterhead (4) is contained on the main shaft (3), main spindle box (2) is fixed on the lathe bed (1), it is characterized in that: bistrique seat (6) is contained on the cross slide way (7), cross slide way (7) is contained on the longitudinal rail (8), on the lathe bed of a side of bistrique (5), be fixed with finishing knife (9), be contained in mill teeth cutterhead (4) on the main shaft of bistrique opposite side (3), main shaft (3), bistrique seat (6) axis at grade, cross slide way (7) and longitudinal rail (8) are respectively by numerical-control motor (10), (11) control.

2, bevel gear mill teeth according to claim 1 shaping cutterhead correction of the flank shape device, it is characterized in that: finishing knife (9) is the diamond grinding wheel dressing cutter.
