【正文】 just the plate, adjust the set of ponents to control the assembly size. This method is relatively easy to adjust the right choices to other ponents of the pensation error, in order to improve the manufacturing precision of the fixture. (3) structural technical Structural technical performance of the fixture for fixture parts manufacturing, assembly, missioning, measurement, and use the performance. Structural elements of the general standard of the fixture parts and castings, and so on, can access to the manual design. Fixture ponents of the processing, maintenance, assembly and measurement process. 1) Note that the processing and maintenance process Fixture connection of the main ponents of positioning screws and pins. In Figure (a) of the pin hole is made throughhole, so that maintenance can pin press out。 shown in Figure (b) pin, the pin hole at the bottom of the horizontal hole demolition。 Figure (c) is monly used with threaded taper pins (GB1182021). (A) The pin hole is made throughhole (b) A transverse hole (c) with threaded Figure pin hole connection process Fig. pin hole connection technology 2) Note that the measurement process of assembly The fixture assembly measurement is an important part of the fixture manufacturing. Assembly of the repair method or the method of adjustment assembly, or submit a test fixture accuracy, should deal with the problem of a good benchmark. In order to fixture assembly, measurement process, we should follow the benchmark uniform principles, to clip the specific surface is uniform benchmarks, in order to facilitate the assembly measurement fixture manufacturing to ensure accuracy. When the basal plane of the fixture can not meet the above requirements, you can set the process holes or craft Boss.
