Matters needing attention in the installation of cam indexer

The cam indexer is a high-precision component. Its production, processing and testing are all carried out by high-precision equipment. Precise processing and correct assembly adjustments obtain the segmentation mechanism required by customers, except in the process of packaging, handling, and transportation. , Strong vibration and rough operation are strictly prohibited. Before the manufacturer is put into use, it is necessary to read the instruction manual strictly, and install and use by professionals. It is not allowed to adjust, disassemble, and assemble the internal facilities without authorization.

Before installing with the motor and other devices, first check the installation surface of the indexer to see if there is any damage on the surface. In the case of slight scratches or damage, simple trimming with oilstone sandpaper, etc.
Judge the correct position of the input shaft and output shaft, install positioning pins as required, and tighten the fastening screws evenly.
What needs to be reminded is that because the cam indexer bears the action of pulsating load moment, the static and dynamic impulse is relatively large, the assembly must be tightened, and the joint parts of the installation must be periodically checked.
The structural characteristics of the cam indexer, its installation surface is relatively perpendicular or parallel to the input and output shafts, and the installation base surface of the equipment must ensure that the input and output shaft directions of the cam indexer are coaxial with the input and output directions of the required equipment , Can not produce deviation and eccentricity. Otherwise it will affect the accuracy of the output, not only can not meet the needs of use, but also seriously damage the cam indexer. Under any circumstances, the cam indexer is strictly forbidden to work under abnormal stress conditions.
When installing the input and output shafts, all the associated connections with the input shaft and output shaft of the cam indexer should be in the direction of rotation without reverse impact and stable rotation.
Attention should be paid when installing the turntable, sprockets, pulleys, gears, flanges, etc. on the input and output shafts of the cam indexer. It is forbidden to hammer and impact vigorously with a hammer, otherwise the needle roller bearings of the cam inside the cam indexer will be affected.
When the input and output shafts are erected, sufficient center adjustment must be carried out first. The input shaft and output shaft of the cam indexer are processed by H6 level, including the hole diameter is also H6 level, so it is relatively smooth when pressed in. Pay attention to the fit of the upper and lower limit deviations between the hole and the shaft, and the fixed coupling key Can't be too loose.
After the cam indexer is installed, when parts processing, accessories, fixtures, and tools are installed, the eccentricity or step error of the working table used in conjunction with it must be detected by the instrument and adjusted and eliminated.
