A positioning drilling rotary table

Abstract

The invention relates to the field of motor drilling tooling structures, in particular to a positioning drilling rotary table; including a base, a turntable and an end cover positioning device; the turntable includes a driving mechanism, a main shaft, a ratchet and a turntable; the base includes a base and the bearing seat set on the upper part of the base; it realizes multiple drilling in one clamping, avoiding the deviation of the drilling position accuracy caused by multiple disassembly and assembly of the end cover; the original single mechanical operation is replaced by the turntable, so that the drilling The process is more convenient, which greatly shortens the processing time of drilling a flange surface of an end cover and improves production efficiency; the designed quarter-point rotary table can accurately realize the drilling of four uniformly distributed holes on the same circumference; this design The structure is distributed vertically, and each part has a simple structure, which is convenient for subsequent maintenance.

Problems solved by technology

When drilling, the blanks of stainless steel motor end covers are mostly made of 304 or 316 stainless steel, and their machining performance such as turning and drilling is poor. Especially in the drilling process, for multiple uniformly distributed holes, it is necessary to Single mechanical action and long-term operation are time-consuming and labor-intensive, and the processing of evenly distributed flange faces on the flange surface requires high technological requirements to ensure that customers can properly assemble the motor on the working machine

For a stainless steel motor end cover with multiple holes evenly distributed, the existing tooling equipment generally has the following deficiencies: most of them only realize the positioning and clamping of the end cover when drilling, and do not solve the problem of one-time clamping. Drilling multiple times requires repeated disassembly and assembly of the workpiece, which leads to deviations in the position accuracy of the drilling and poor process quality; the operation is complicated, the installation is difficult, and the production efficiency is not high in actual production applications.
