1、 maximize availability - first of all, consider avoiding single specificity, sharing as much as possible, and consider the convenience of changing type.
2、 the simplicity of the mechanism - - the complexity of the mechanism, the frequency of failures, and the shortening of the service life of the equipment; therefore, the most simplified mechanism should be adopted on the basis of guaranteeing its function.
3、minimize manufacturing expenses.
4、as far as possible the use of standard parts, the use of standard parts can save maintenance time, improve equipment operation rate, shorten manufacturing time, reduce product cost.
Attention should be paid to the design of the gauge for body welding assembly (1) the shape of the body is irregular, so the workpiece is taken / released smoothly. (2) ensure the welding operation, welding tongs to facilitate the operation. (3) the clamping direction takes into account the interference between the units and the clamping action is easy. (4) minimizing the clamping / releasing angle can save energy and reduce the volume of equipment, so as to reduce the cost. (5) all the clamping mechanisms shall select the units that are fast and correct and meet the requirements of the clamping force. (6) to ensure sufficient stiffness, under external forces can not be deformed. (7) the manufacture of jigs is easy. - using easy to buy materials. To ensure the accuracy and possibility of manufacturing process. The possibility of the threaded hole - drilling test and bolt dismounting the possibility of drilling. (8) checking the carrying capacity of heavy weights such as rings. (9) consider the maintainability of equipment, such as wear, heat treatment, lubrication, etc.. (10) consider the safety - take security bar, emergency stop switch and other security related measures, to ensure the safety of the operator. (11) to avoid feeding and assembling of defective products。
