Embodiment Construction

[0016] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0017] see figure 1 , a cam indexing device for realizing a large index number is mainly composed of an indexing box 1, an input shaft 2, an output shaft 3, an arc cam body 4, and an indexing plate assembly. The input shaft 2 and the output shaft 3 are staggered and perpendicular to each other, the arc cam body 4 is installed on the input shaft 2 through a key connection, and the index plate assembly is installed on the output shaft 3 through a key connection. The index plate assembly includes an index plate 5 and a plurality of rollers 6, the axes of the rollers are all perpendicular to the axis of the index plate, and all the rollers 6 are connected radially and uniformly along the circumference of the index plate through threaded connection and pin connection. Fixed on the index plate 5, the number of rolle...

Abstract

The invention relates to a cambered cam indexing device for realizing large indexing number, which mainly includes an indexing box, an input shaft, an output shaft, a cambered cam body fixed on the input shaft, and an indexing plate fixed on the output shaft components. The axes of the rollers in the indexing plate assembly all intersect with the axis of the indexing plate, and the input shaft and the output shaft are staggered and perpendicular. The ridge on the cam body meshes with the roller in the indexing plate assembly, and the contour of the ridge is divided into four stages: the first stop section - the first index section - the second stop section - the second index section , the contours of the ridges of the two indexing sections are variable-lead spiral ridges, the first stop section is a circular ridge, and the second stop section is two circular ridges. During one rotation of the cam body, the indexing plate has two indexing rotations and two intervals, and the indexing angle of the output shaft each time is equal to half of the central angle between the rollers, that is, the indexing number is equal to twice the number of rollers. , without changing the geometric size of the indexing plate, it can achieve a large number of indexing.

Description

technical field [0001] The invention relates to an intermittent transmission device, in particular to an arc cam indexing device for realizing a large index number, and belongs to the field of mechanical technology. Background technique [0002] The arc cam indexing device is mainly composed of an arc cam body and an indexing plate with rollers. The cam pushes the rollers on the indexing plate to convert the continuous rotation of the cam into periodic intermittent motion of the indexing plate. . Because of its small impact and vibration, stable and reliable operation, and good dynamic characteristics, the arc cam indexing device is often used in high-precision indexing mechanisms and high-speed automatic machines. At present, in the arc cam indexing mechanism on the market, during each indexing process, the rotation angle of the indexing plate is equal to the central angle between the rollers, that is, the number of indexing is equal to the number of rollers. When the num...
