Abstract
The utility model provides a cam indexing means, includes cylindrical cam and graduated disk, the quotation of graduated disk is being close a plurality of gyro wheels of circumferencial direction evenly distributed installation of graduated disk, the axis of gyro wheel with the axis of graduated disk is parallel, cylindrical cam's axis with the axis of graduated disk is perpendicularly crisscross. Above -mentioned device is in when cylindrical cam's fin is cut into between two gyro wheels, there is not the back clearance between fin and the gyro wheel.
Description
Technical field
The utility model is relevant with the transmission device of intermittent movement, in more detail, is a kind of Cam indexing device.
Background technology
As Fig. 1, a kind of known Cam indexing device, is arranged at a datum level of central processing machine, for carrying the work rotary disk of described processing machine.Described known devices comprises the force-output shaft rotary disk 10 coaxially arranged with described work rotary disk, and described force-output shaft rotary disk 10 is equidistantly provided with roller 11 in circumferential location; One cam inputting shaft 12 with the fin 14 of its cam 13 between two rollers 11, motor (not shown) turns described cam inputting shaft 12, described cam 13 is by the contact of fin 14 with roller 11, described force-output shaft rotary disk 10 is rotated according to the hand of spiral of described cam 13, a torque is exported to described work rotary disk and drives its rotation.
The shortcoming of known devices is, the axle center of roller 11 is vertical with the axle center of force-output shaft rotary disk 10, and when the fin 14 of cam 13 is cut between two rollers 11, fin 14 and roller 11 define obvious back clearance 15.What described back clearance 15 caused cam inputting shaft 12 pairs of force-output shaft rotary disks 10 enters power dispersion, and transmission efficiency reduces, and rocks, noise, and roller 11 bears excessively partially power and the problem such as easily damaged.
Utility model content
The technical problems to be solved in the utility model is: the fin of known Cam indexing device and the back clearance of roller cause disperseing into power, and transmission efficiency reduces, and rocks, noise, the problems such as roller is easily damaged.
The utility model solves the problems of the technologies described above taked scheme: a kind of Cam indexing device, comprise cylindrical cam and index dial, the card of described index dial is uniformly distributed at the circumferencial direction close to described index dial installs some rollers, the axis of described roller and the axis being parallel of described index dial, the axis of described cylindrical cam and the axis of described index dial are vertical interlaced.
The beneficial effects of the utility model are: the utility model provides a kind of Cam indexing device, when the fin of wherein said cylindrical cam is cut between two rollers, without back clearance between fin and roller.Without back clearance cooperation, the enter power of cylindrical cam to index dial is concentrated, promote transmission efficiency, without rocking, noiselessness, reduce the probability that roller damages because bearing excessive power partially, Cam indexing device has good durability.
Accompanying drawing explanation
Fig. 1 is the plane of known Cam indexing device.
Fig. 2 is the index dial stereo appearance figure of the utility model Cam indexing device.
Fig. 3 is the index dial front view of the utility model Cam indexing device.
Fig. 4 is the side view of the utility model Cam indexing device.
Detailed description of the invention
For ease of central idea of the present utility model is described, hereby express with specific embodiment.In embodiment, various different object is described in the ratio, size, deflection or the displacement that are suitable for illustrating, but not is drawn in the ratio of actual components, and conjunction is first chatted bright.
As Fig. 2, Fig. 3 and Fig. 4, the utility model Cam indexing device, comprises a cylindrical cam 20 and one division dish 30; The card 31 of described index dial 30 is uniformly distributed in circumference 32 direction close to described index dial 30 installs some rollers 33, the axis of described roller 33 and the axis being parallel of described index dial 30, the axis of described cylindrical cam 20 and the axis of described index dial 30 are vertical interlaced.
The fin 21 of described cylindrical cam 20 is cut between two rollers 33, motor (not shown) turns described cylindrical cam 20, by the contact of fin 21 with roller 33, described index dial 30 is rotated according to the hand of spiral of described cylindrical cam 20, thus export a torque.
Because of the axis of described roller 33 and the axis being parallel of described index dial 30, and the axis of the axis of described cylindrical cam 20 and described index dial 30 is the design of vertical interlaced, eliminates the back clearance between fin 21 and roller 33.Fin 21 and roller 33, without the state of back clearance, make the power that enters of cylindrical cam 20 pairs of index dials 30 concentrate, promote transmission efficiency, and without rocking, noiselessness, reduce the probability that roller damages because bearing excessive power partially, Cam indexing device has good durability.
Claims (1)
