Industrial automation equipment, how to choose the manufacturing process of connecting automatic assembly machines

The choice of cooperation in the manufacturing process of connection automatic assembly machine

The selection of the tolerance level of the datum system connected to the automatic assembly machine determines the tolerance zone of the datum hole or the datum shaft, and the size of the tolerance zone of the non-reference part, so the selection of the fit is actually to determine the position of the tolerance zone of the non-reference part, that is Select the basic deviation of non-standard parts to pass.

For the interference fit, according to the size of the transmitted load, according to the plastic theory to calculate the allowable minimum and maximum interference, so as to select the appropriate type of fit, GB/T 5371-2O04 limit and the calculation and selection of the interference fit has been made detailed regulations. For transition fits, there is currently no suitable calculation method.

The basic deviations of various codes represent various coordinations under certain conditions, so the choice of coordination is also a question of how to choose the basic deviations. There are three methods for selecting and matching automatic assembly machines: calculation method, experimental method and analogy method.

The calculation method determines the required clearance or interference according to certain theories and formulas, so as to carry out the design of limit and fit, mainly used for automatic assembly machine clearance fit and interference fit. For example, for the clearance fit of plain bearings, the minimum allowable inter-ring should be calculated according to the theory of liquid lubrication. Then select the standard fit type.

The test method is to determine the clearance or interference by experiment or statistical analysis. This method is reasonable and reliable, but the cost is high, so it is only used for the key cooperation of the main products of the automatic assembly machine.

After researching, analyzing and comparing similar machines and parts, and selecting limits and coordination based on the experience of predecessors, this is the most widely used and the main method at present. In the actual work of automatic assembly machine, the most widely used is the analogy method, that is, referring to the existing similar machines or similar structures, the cooperation verified by practice is compared with the use conditions of the designed parts, and after correction, the matching is determined.
