Embodiment Construction

[0018] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0019] see figure 1 with figure 2 , A cylindrical cam indexing device is mainly composed of an indexing box 1, an input shaft 2, an output shaft 3, a cylindrical cam body 4, an indexing plate 5 and a plurality of rollers 6. The indexing box 1 is a casting, and the output shaft hole sleeve 10 is cast inside, and the output shaft hole sleeve runs through the box body, and is connected with the box body arm through a plurality of reinforcing ribs 11 to increase the rigidity of the output shaft hole sleeve; Bosses 12 are also cast on the two side arms of the box, and input shaft holes are provided in the bosses, and the axes of the input shaft holes and the output shaft holes are staggered and perpendicular to each other. The input shaft 2 and the output shaft 3 are staggered and perpendicular to each other. One...

Abstract

The invention relates to a cylindrical cam indexing device, which mainly comprises an indexing box, an input shaft, an output shaft, a cylindrical cam body, an indexing disc and rollers, wherein the cylindrical cam body is fixedly connected onto the input shaft; the input shaft and the output shaft are staggered and perpendicular; a peach-shaped groove raceway is processed in the ring surface of the outer side of the indexing disc, and the indexing disc is supported on the indexing box through a four-point contact ball bearing; the axis of each roller is parallel with that of the indexing disc; the cylindrical cam body is formed by encircling a cylindrical matrix with a cam lobe crest; the cam lobe crest comprises four stages: a first intermittent section, a first indexing section, a second intermittent section and a second indexing section; the first intermittent section is a circular ring cam lobe crest, the second intermittent section is two circular ring cam lobe crests, and each indexing section is two spiral cam lobe crest. In a process that the cam body rotates one cycle, indexing rotation and intermittence are separately performed by the indexing disc for two times, and an indexing number is twice the number of the rollers; and without changing a geometric size of the indexing disc, a large indexing number can be realized.

Description

technical field [0001] The invention relates to an intermittent transmission device, in particular to a cylindrical cam indexing device, which belongs to the technical field of machinery. Background technique [0002] The cylindrical cam indexing device is formed by meshing the cylindrical cam body on the input shaft and the indexing disc roller on the output shaft. The cam pushes the roller on the indexing disc to convert the continuous input rotary motion into indexing. The periodic intermittent rotary motion of the disc. Cylindrical cam indexing device, although the high speed and precision are not as good as arc cam indexing device, but because of the lower price of cylindrical indexing cam, it is easier to manufacture, and this type of indexing mechanism can realize multi-index output, suitable for medium and low speed Under the circumstances, it is required to stop more times within a week, such as light bulb machinery, ceramic machinery, tobacco machinery, large infu...
