Motor frame inner circle and stop processing technology
The machining of the boring and the stop in the base is the key to the machining of the base. It can be processed on a lathe or on a trampoline. Different motor manufacturers will tailor the unique processing technology according to the specific structure of the product, but the dominant requirements of the process will not change, that is, the coaxiality between the ends of the two ends and the inner ring of the frame, the end faces of the two ends are opposite to each other. The verticality of the central axis, as well as the tolerance requirements of the mating components. Today, Ms. is involved in a rough communication, and I am willing to be able to leave a message and express my opinions.
Lathe processing machine seat technology
Motor mounts for H200 and below are generally machined on horizontal lathes or turret lathes, while H225 and above are generally machined on vertical lathes.
When processing the first end stop, the outer circle and the two ends of the blank of the base must be aligned to make the wall thickness of the machined frame after processing substantially uniform. When the other end stop is machined, the first end stop and the end face are positioned. In order to ensure the coaxiality of the ends of the two ends, a cast iron chassis is fixed on the lathe workbench, and the chassis of the fine car is fixed so as to achieve a proper tolerance with the first end of the frame. The chassis thus manufactured is a stop positioning tire. When the first end stop of the base is fixed on the positioning tire, the dust on the contact surface should be cleaned, so that the base end and the end face and the bottom plate can be closely pressed.
Because the positioning of the positioning tire is installed on the lathe to close the finishing car, the center line of the positioning tire stop is exactly the same as the center line of the lathe work table. Therefore, the positioning of the second end stop and the inner circle by positioning the tire stop can ensure the coaxiality between the end end and the inner end, and the ring runout of the end line and the end line of the end end of the end is not superior. When clamping, apply force evenly around the base in the axial direction, so that the base is pressed against the positioning tire. After roughing the car, the pressing force should be properly relaxed, and then the car should be finished to avoid deformation of the frame due to excessive pressing force.
