Metal winding gasket outer ring lathe groove chuck

Abstract

A metal winding gasket outer ring lathe groove chuck comprises a three-jaw chuck and fan shaped paws, wherein the fan shaped jaws are three in number which are fixed on three jaws of the three-jaw chucks respectively; the three fan shaped jaws form a hollow circular ring shape and the intervals range from 8 mm to 13 mm; the fan shaped jaw upper lathe is provided with sequentially descending arc steps; the arc steps are 10 to 15 in number. According to the metal winding gasket outer ring lathe groove chuck, steps needed of various sizes are formed on the fan shaped jaws sequentially towards inner lathe, and outer rings of various models can be clamped through loosening or tightening the three-jaw chucks; when wingding gasket outer ring is processed, contact area of the fan shaped jaws and work pieces is increased, so that deformation of work pieces is reduced, the clamping is reliable, flexible and convenient, jumping do not occur on the end surface, speed of clamping parts is faster, time is saved greatly, and parts processing accuracy can be more guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical automation manufacturing, in particular to a metal winding pad outer ring groove chuck. Background technique [0002] Generally, the outer ring of the wound mat on the market is generally stamped, welded or welded before washing the tank, and according to the standard requirements, the outer ring of the wound mat should be flat, and the flatness tolerance should be less than 1%; the ring groove It should be concentric with the inner and outer circles, and should be symmetrical with the two ends; in the past, a three-jaw or four-jaw chuck was used to process the outer ring of the metal winding pad on a lathe, and a v-shaped groove should be made on the inner diameter of the thin ring of 2-3 mm. The part cannot be reliably clamped, and the force is slightly larger to make it distorted and deformed. The force is small but the part cannot be reliably clamped, so that the V-groove made by the car is not on th...

[0002] Generally, the outer ring of the wound mat on the market is generally stamped, welded or welded before washing the tank, and according to the standard requirements, the outer ring of the wound mat should be flat, and the flatness tolerance should be less than 1%; the ring groove It should be concentric with the inner and outer circles, and should be symmetrical with the two ends; in the past, a three-jaw or four-jaw chuck was used to process the outer ring of the metal winding pad on a lathe, and a v-shaped groove should be made on the inner diameter of the thin ring of 2-3 mm. The part cannot be reliably clamped, and the force is slightly larger to make it twisted and deformed. The force is small but the part cannot be reliably clamped, so that the V-groove made by the car is not on the center of the ring, which is very difficult and cannot guarantee the processing accuracy at all.
