Description
Technical Field
The utility model relates to a used revolving stage drive mechanism of machining center.
Background
The turntable is adopted in the machining center, the driving mechanism adopted by the indexing motion of the dial disc is a steel ball cam speed reducing mechanism, and the large steel balls and the small steel balls arranged in the grooves uniformly distributed in the circumferential direction of the turret rotate in a matched mode to transmit power to the turret so as to realize the indexing motion of the dial disc. However, in practical application, the small steel balls in the grooves are pushed out of the retainer by the large steel balls after being stressed, so that the transmission stability is reduced, and the indexing precision is influenced.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the utility model provides a machining center turntable transmission mechanism which can effectively improve the transmission stability.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a machining center revolving stage drive mechanism, includes the box, rotates the cambered surface cam of establishing in the box and with cambered surface cam transmission complex capstan head, installs YRT revolving stage bearing in the box, and the bearing enclosing cover is installed to the box up end, the capstan head suit is on YRT revolving stage bearing enclosing ring, and the calibrated scale that is located the box outside is installed to the rim of a circle other end of YRT revolving stage bearing, the capstan head outer peripheral face on the equipartition have the cam groove, the arc slot has been seted up to the cam groove bottom surface, the arc slot internal row has little steel ball, be equipped with in the cam groove with the big steel ball of cambered surface cam's arc slot roll complex, big steel ball extrusion little steel ball rolls.
Furthermore, in order to keep the large steel balls to roll stably, a retainer is fixed on the periphery of the turret, and the large steel balls are clamped in the retainer to roll.
The utility model has the advantages that: the utility model discloses a big steel ball promotes the sphere rolling friction mode transmission power of little steel ball, and the wearability is good, and the noise is little when high-speed moving, and little steel ball is restricted to make cyclic motion in the arc slot during atress, is difficult for being extruded outside the holder by big steel ball to driven stability and graduation precision have been improved.

In the figure: 1. the device comprises a box body, 2 parts of arc-shaped cams, 3 parts of a turret, 4 parts of a YRT turntable bearing, 5 parts of a bearing outer cover, 6 parts of a dial, 7 parts of a cam groove, 8 parts of an arc-shaped groove, 9 parts of small steel balls, 10 parts of large steel balls and 11 parts of a retainer.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-5, the machining center turntable transmission mechanism comprises a box body 1, an arc cam 2 rotatably arranged in the box body 1 and a turret 3 in transmission fit with the arc cam 2, wherein a YRT turntable bearing 4 is arranged in the box body 1, a bearing outer cover 5 is arranged on the upper end surface of the box body 1, the turret 3 is sleeved on the YRT turntable bearing 4, and a dial 6 positioned outside the box body 1 is arranged at the other end of a shaft ring of the YRT turntable bearing 4.
The outer peripheral surface of the turret 3 is uniformly provided with cam grooves 7, the periphery of the turret 3 surrounding the cam grooves 7 is fixed with a retainer 11 by adopting a countersunk screw, the bottom surface of the cam grooves 7 is provided with arc-shaped grooves 8, small steel balls 9 are arranged in the arc-shaped grooves 8, large steel balls 10 which are in rolling fit with the arc-shaped grooves of the arc-shaped cams 2 are arranged in the cam grooves 7, and the large steel balls 10 are clamped in the retainer 11 to roll.
Power is transmitted through the arc cam 2, when the arc cam 2 runs, the large steel balls tangent to the cam grooves are driven to roll in a rolling friction mode, the small steel balls 9 are extruded by the large steel balls 10 into the arc grooves 8 to roll circularly so as to drive the turret 3 to rotate, the rotation of the turret 3 drives the shaft ring of the turntable bearing 4 to rotate, and finally the dial 6 is driven to rotate so as to realize indexing motion of the turntable.
The utility model discloses a big steel ball 10 promotes the sphere rolling friction mode transmission power of little steel ball 9, and the wearability is good, and the noise is little when high-speed moving, and little steel ball 9 is restricted to be made cyclic motion in arc slot 8 during the atress, outside difficult being extruded holder 11 by big steel ball 10 to driven stability and graduation precision have been ensured.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
