Description

Fixed bead ring processing device

Technical Field

The utility model relates to the technical field of machining, in particular to a bead ring machining device.

Background

The fixed bead ring is used for clamping the steel balls, and a product formed by assembling the fixed bead ring and the fixed bead ring can help the vortex compressor to realize plane swing. Specifically, the main body of the bead ring is circular, and usually, 16 bead fixing holes for installing steel balls are formed in the main body, and the orifices of the bead fixing holes are provided with conical surfaces, so that part of the steel balls protrude out of the surface of the bead ring. When the steel balls are clamped by the ball fixing rings, the front ball fixing rings and the rear ball fixing rings are generally matched to clamp the steel balls in the ball fixing rings, and the steel balls are exposed from the ball fixing holes of the front ball fixing rings and the rear ball fixing rings respectively. Therefore, the accuracy of the position of the bead hole on the bead ring is particularly important, and is one of the important control sizes of products. This is because, if the positional accuracy of the ball fixing hole is not good, the front ball fixing ring and the rear ball fixing ring are likely to cause positional deviation between the front ball fixing hole and the rear ball fixing hole which clamp the same steel ball when being connected, thereby affecting the smoothness of the rotation of the steel ball in the ball fixing ring and further affecting the swinging flexibility of the scroll compressor.

Chinese patent publication No. CN209850460U discloses a servo cutting table workpiece clamp for processing the conical surface of the bead ring, the structure of the clamp is complex, the number of parts is large, and the precision of the clamp is affected due to accumulated tolerance (part processing tolerance, assembly tolerance) after assembling a plurality of parts, thereby affecting the processing precision of the bead ring. In addition, the clamp drives the main shaft to rotate through the servo motor, and when the servo motor is stopped, the rotation angle of the main shaft is inaccurate due to unstable braking. Therefore, the bead fixing ring processed by the fixture is difficult to meet the requirement of increasingly improved product precision in the position degree of the bead fixing hole.
