Description
Technical Field
The utility model relates to machining, in particular to an immediately-adding tool for a speed reducer cover.
Background
The blank of the reducer cover 100 shown in fig. 1-3 is required to be cut into a stepped hole 104 shown in fig. 3 after 2 round tables 101 on the inner end surface are cut to a set height as shown in fig. 1-2, and a through hole 105 shown in fig. 3 is also required to be drilled in the center of the countersink 102. However, since the decelerator cover 100 is a kind of revolution body, no suitable structure can achieve circumferential positioning except that the center hole 103 in the center thereof is suitably positioned as the center. If a limiting block is arranged on one of the round tables 101 for circumferential positioning, however, the limiting block will interfere with the cutter due to the small height of the round table 101 after cutting. The existing solution is to use a common machine tool and manually clamp a single piece for processing, and the processing efficiency is very low. If a numerical control machine such as a vertical machining center is used, the tool is required to be consistent with the circumferential positioning of the same batch of reducer covers 100, so that the unified original coordinates of the tool are determined.
