Bearing capper

The present invention relates to a bearing manufacture equipment, particularly relates to a bearing capping machine. The capping machine includes a hydrostatic press, an air cylinder, an inner lane locater, an upper mould and a lower mould, wherein the upper mould connects with the screw rod of the hydrostatic press; the lower mould connects with the working table of the hydrostatic press; the inner lane locater locates above the lower mould in central position of the lower mould; the air cylinder locates below the lower mould and can pass the lower mould to contact with the inner lane locater and push-out the bearing work piece; the lower mould holds the outer lane of the bearing; the inner lane locater holds the inner lane of the bearing. The present invention characterized in that the shape and size of the intersecting surface of the upper and lower mould matches the outer lane of the bearing, and the upper and lower mould are provided with a T-shaped groove to adjust the central position of the upper and lower mould to align the upper and lower mould. By adopting above technical solution, the center locating of the upper and lower mould is accurate, operation is easy, hence capping speed and percent of pass are improved significantly.
