Abstract
The invention discloses a slide tensioning mold for constant-speed centering spheres, relating to the field of mechanical manufacturing of constant-speed centering spheres of a four-wheel drive vehicle. When the mold is in use, constant-speed centering spheres of a four-wheel drive vehicle are placed into an expander on which a plurality of middle slots are formed, and the constant-speed centering spheres slide forward and backward through a positioning shaft with a screw nut, so that the expander can constantly perform in-situ expansion and restoration. The slide tensioning mold comprises three major parts, namely a special mold transition seat for the external spherical surface grinding of the constant-speed centering sphere parts of the four-wheel drive vehicle; the special mold spherical expander for the external spherical surface grinding of the constant-speed centering spheres of the four-wheel drive vehicle, which is designed into a special structure with slots formed at the end part and is matched with the constant-speed centering spheres; and the special mold slide screw nut positioning shaft for the external spherical surface grinding of the constant-speed centering spheres of the four-wheel drive vehicle, wherein the positioning shaft can slide forward and backward and be matched with the special mold spherical expander for the external spherical surface grinding of the constant-speed centering spheres of the four-wheel drive vehicle. In the slide process, the mold can be tightened and loosened to control the grinding of the constant-speed centering spheres. The product processed by the slide tensioning mold is high in precision and efficiency, low in cost, environment-friendly and energy-saving.
