Description

A kind of combination process tool of processing electric motor end cap

Technical field

The utility model relates to a kind of process tool of motor component, belongs to motor component machining tool technical field.

Background technology

Electric motor end cap is mounted in the parts that driven equipment is accepted in the motor end, and it is to cooperate with seam on the electric machine stand through the seam on the end cap to connect the location.Be provided with bearing chamber in the electric motor end cap, be provided with bearing in the bearing chamber, the end that bearings motor shaft, motor shaft stretch out end cap connects with driving parts.It is thus clear that each connects the height of machining accuracies such as end face, bearing chamber end cap, be directly connected to product quality, price grade and the service life of motor.So when the processing end cap, the axiality of the depth of parallelism, end cap and the bearing of each end face of assurance end cap, end face run-out, the round precision of beating etc. are all very important.

At present, to the processing of end cap, be after through turning attachment end cap being carried out the above clamping location of twice or twice in the industry, carry out repeatedly the multiplex (MUX) and go on foot turning and form.Its processing technology generally comprises following steps: at first with the claw of machine chuck technology lug clamping location with end cap, and rough turn, finish turning bearing chamber internal diameter, bearing one transverse plane, seam cylindrical and end face and chamfering; Then end cap is transferred face, connect the location through the end cap seam with the frock clamp of lathe, finish turning another bearing chamber end face and chamfering are accomplished end cap processing.Because just there is trueness error in the frock clamp of every lathe itself, and the locating surface work in-process of anchor clamps, also can produces wearing and tearing in various degree and cause error.Adding the man-hour end cap turns and carries out clamping location processing more again; Certainly will cause the end cap machining accuracy to reduce, and the end cap that adopts this processes to go out do not have interchangeability, production efficiency is low; Especially to the bigger motor of seat No., need bigger lathe to process.If occur vibration in the transportation or ressemble after need dismantling because of a variety of causes, then end face run-out and circular runout all can't guarantee.

The utility model content

To the technical problem of above-mentioned existence, the purpose of the utility model is: proposed a kind of assurance machining accuracy, the combination process tool and the method for using thereof of the processing electric motor end cap of a clamping location.

The technical solution of the utility model is achieved in that a kind of combination process tool of processing electric motor end cap, comprises circular cutter holder, facing tool, hole boring cutter and 45 ° of inclined to one side lathe tools of mounting cutter; Said knife rest is a rectangle, and four angles on the knife rest are four stations of mounting cutter; Said facing tool, hole boring cutter and 45 ° of inclined to one side lathe tools are installed on the station of circular cutter holder respectively at interval; Said facing tool and hole boring cutter are installed on two adjacent stations, and the knife bar of the knife bar of hole boring cutter and facing tool is perpendicular; Said 45 ° of inclined to one side lathe tools are installed on the station adjacent with facing tool through a lengthening knife bar; Said lengthening knife bar is perpendicular to the knife bar of facing tool; The knife bar of said 45 ° of inclined to one side lathe tools is vertically fixed on the top of lengthening knife bar.

Preferably, said facing tool is 45 ° of end face finishing tools.

Because the utilization of technique scheme, the utility model compared with prior art has advantage:

The combination process tool of the processing electric motor end cap of the utility model scheme; During use with behind the disposable clamping of the end cap location; Adopt the combination process tool, the multiplex (MUX) goes on foot fine finishining and accomplishes, and has avoided the error because of transferring face clamping location to produce in the end cap processing; Improved the machining accuracy of end cap, effectively guaranteed circular runout and the axial runout of machine shaft the support seam.
