Problems solved by technology

In spinning production, in order to ensure the accuracy indicators such as straightness and roundness of spinning parts, the blank clamping requires good neutrality. The neutrality refers to the coincidence degree of the blank axis and the mold axis. Neutrality is not easy to grasp, the quality of the parts produced by spinning is poor, and it cannot meet the design requirements, which increases the processing difficulty of the subsequent process. There is no device for centering the blank on the market.

Abstract

The invention discloses a blank centering device. The blank centering device comprises a hydraulic cylinder with a piston rod, two gears, two gear mounting plates and two blank oscillating rods, wherein the two gears are meshed with each other and separately fixed on one end of each gear mounting plate, the other end of each gear mounting plate is hinged with one end of each blank oscillating rod through a hinge pin, a hole is formed on the other end of each blank oscillating rod; a material support rod is fixed in each hole and perpendicular to the corresponding blank oscillating rod; and the piston rod of the hydraulic cylinder is hinged with one blank oscillating rod through a hinge pin. The centering device can effectively solve the problem that the centering property is poor when the blank is arranged and clamped manually, and ensure the spinning quality of the spinned part; and the device can be used in the numerical control machine tools such as the numerical control lathe and the milling machine and have high adaptability.

Description

technical field [0001] The present invention relates to a centering device, in particular to a blank centering device. Background technique [0002] Spinning technology, as a manufacturing process for parts forming, is now more and more widely used in the automobile industry, construction machinery industry and military enterprises. The application of spinning technology can produce products that are closer to the final shape of the parts, which can effectively improve the strength of materials, shorten processing hours, and improve production efficiency. The development of design and manufacturing of spinning machines is the premise and basis for the development of spinning technology. In spinning production, in order to ensure the accuracy indicators such as the straightness and roundness of the spinning parts, the blank loading requires good alignment, which refers to the coincidence of the blank axis and the die axis. Neutrality is not easy to master, and the quality of...
