Swing device for eccentric arc grinding

Abstract

The invention discloses a swing device for eccentric arc grinding. The swing device comprises a driving part, a transmission structure and a swing structure, wherein the transmission structure is connected with the driving part and the swing structure; the transmission structure comprises a transmission wheel, a transmission rod and a connecting rod; the transmission wheel sleeves an output shaftof the driving piece, and a notch is formed in the transmission wheel; the swing structure comprises a deflection frame, a deflection frame fixing piece and a wedge block fixing piece. The swing device disclosed by the invention is simple in structure and convenient to use, the purpose of concentricity by eccentric adjustment is achieved through the deflection frame; a motor is started to do cam motion; the swing arc length is adjusted through the arc length of up-down deflection, and grinding machining of the eccentric arc of the wedge block is achieved; the small ends of the two ends of thewedge block and the deflection frame are fastened and clamped through the wedge block fixing piece, and the positioning precision of the swing device is guaranteed.

Description

technical field [0001] The invention relates to the field of backstop processing, in particular to an oscillating device for eccentric arc grinding. Background technique [0002] The backstop is a raceway formed by several heterosexual wedges distributed in the inner and outer rings according to certain rules. Each wedge adopts two unique torsion springs, which can ensure the backstop without gap and the safety of each wedge when the force is applied. Stress synchronicity, driven by the lifting gravity of the material, the inner ring of the backstop is reversed to drive the special-shaped wedge to deflect, and the wedge of the backstop and the inner and outer rings are tightly wedged into one, realizing the backstop function without gaps, according to the backstop Due to factors such as the performance and structural characteristics of the special-shaped wedge block, the wedge block has a special-shaped structure and high precision requirements. Power performance, etc. [...
