Abstract
The invention provides an improved spherical-surface double-raceway dresser, which has a free running preventing function that can ensure that a machine tool does not generate a dressing angle rotation offset under interference of an external force even in a power-off state and therefore guarantee the normal operation of the machine tool. The dresser comprises a dressing driving device and a dressing turning device, wherein the dressing driving device comprises an arc-shaped bracket and a servo motor. The dressing turning device comprises an arc-shaped spindle and a diamond pen. The dresser is characterized in that the dressing driving device also comprises a reducer, wherein the input shaft of the reducer is connected with the shaft of a servo motor through a coupler; and the output shaft of the reducer is connected with the arc-shaped spindle by a coupler.
Description
Technical field
The present invention relates to the technical field of grinding machine components, be specially the two raceway trimmers of a kind of improved sphere.
Background technology
The two raceway trimmers of existing sphere as shown in Figure 1, comprise finishing drive unit, finishing slewing equipment, the finishing drive unit comprises arched frame 1, servomotor 5, the finishing slewing equipment comprises arc main shaft 2, diamond pen 3, servomotor 5 directly drives arc main shaft 2 revolutions by shaft coupling 4, makes the diamond pen swing trimming wheel that is contained in alignment of shafts position.Because servomotor moment is less, if being subjected to external force in turning course disturbs, will make the finishing angle produce error, and when lathe cuts off the power supply, being subjected to external force disturbs, can occur equally repairing the angle rotary deviation, will cause diamond pen and emery wheel to bump against when starting shooting once more, influence the normal use of lathe.
Summary of the invention
At the problems referred to above, the invention provides the two raceway trimmers of a kind of improved sphere, it has the anti-function that walks; if when promptly in turning course, being subjected to external force interference or lathe outage; be subjected to external force and disturb, also can not produce finishing angle rotary deviation, thereby guarantee the lathe operate as normal.
Its technical scheme is such: the two raceway trimmers of a kind of improved sphere, it comprises finishing drive unit, finishing slewing equipment, described finishing drive unit comprises arched frame, servomotor, described finishing slewing equipment comprises arc main shaft, diamond pen, it is characterized in that: described finishing drive unit also comprises decelerator, described input shaft of speed reducer is connected with the axle of described servomotor by shaft coupling, and the output shaft of described decelerator is connected with described arc main shaft by shaft coupling.
Because the present invention has adopted decelerator; increased revolution finishing moment; it is little disturbed by external force; thereby prevent that trimmer from walking; when lathe is in off-position; the latching characteristics of decelerator also can be avoided can not producing finishing angle rotary deviation when being subjected to external force and disturbing, thus operate as normal when guaranteeing that lathe is started shooting once more.
(4) description of drawings
Fig. 1 is the two raceway trimmer structural representations of existing sphere;
Fig. 2 is the two raceway trimmer structural representations of the improved sphere of the present invention.
(5) specific embodiment
See Fig. 2, the two raceway trimmers of the improved sphere of the present invention, comprise the finishing drive unit, the finishing slewing equipment, the finishing drive unit comprises arched frame 1, servomotor 11, decelerator 8, the finishing slewing equipment comprises arc main shaft 2, diamond pen 3, arc main shaft 2 is installed on the arched frame 1, diamond pen 3 is loaded on the centre position of arc main shaft 2, servomotor 11 is connected with decelerator 8 by motor cabinet 10, decelerator 8 is installed on the mount pad 6, the power shaft of decelerator 8 is connected with servo motor shaft 4 by shaft coupling 5-1, the output shaft 7 of decelerator 8 is connected with arc main shaft 2 by shaft coupling 5-2, servomotor 11 drives decelerator 8 by shaft coupling 5-1 and power shaft 9, and decelerator 8 drives arc main shaft 2 by output shaft 7 and shaft coupling 5-2 and realizes swing revolution finishing action.
Because the present invention has adopted decelerator 8; decelerator 8 has enlarging function; the less moment that makes servomotor 11 outputs is by behind the decelerator 8; increased revolution finishing moment; can effectively prevent to be subjected in the dressing process influence that external force is disturbed, when lathe was in off-position, the latching characteristics of decelerator 8 also can be avoided when being subjected to the external force interference in addition; can not produce finishing angle rotary deviation, thus operate as normal when guaranteeing that lathe is started shooting once more.
Claims (1)
1. two raceway trimmers of an improved sphere, it comprises finishing drive unit, finishing slewing equipment, described finishing drive unit comprises arched frame, servomotor, described finishing slewing equipment comprises arc main shaft, diamond pen, it is characterized in that: described finishing drive unit also comprises decelerator, described input shaft of speed reducer is connected with the axle of described servomotor by shaft coupling, and the output shaft of described decelerator is connected with described arc main shaft by shaft coupling.
