Abstract

The invention discloses a magnesium alloy artificial limb connector and a manufacturing method thereof. The artificial limb connector is provided with a cylindrical main body, wherein the cylindrical main body is provided with two parallel lateral surfaces; the lower parts of the other two lateral surfaces of the cylindrical main body are cylindrical surfaces, the middle parts are big end down circular conical surfaces, and the upper parts are revolution surfaces similar to spherical surfaces; the upper surface of the cylindrical main body is provided with a big end up four-arris platform; the bottom surface of the cylindrical main body is provided with a triangular wedge-shaped groove; and the apex angle of the wedge-shaped groove is 90 degrees. In the manufacturing method, a formed turning tool is adopted to finish the appearance of a blank of the artificial limb connector by performing only one turning to greatly reduce the processing cost, and an aging treatment is performed to ensure that the magnesium alloy has the tensile strength of 280 to 300 MPa, the specific elongation of 12 to 14 and the Webster hardness of 13 to 14, so the magnesium artificial limb connector completely meets the requirements on service performance, and provides an effective guarantee for obtaining a portable and flexible artificial limb.

Description

technical field [0001] The invention relates to prosthetics, in particular to a magnesium alloy prosthetic connecting head and a manufacturing method thereof. Background technique [0002] Modern science and technology are changing with each passing day. Many advanced technologies have been applied to human rehabilitation. Prosthetics have also made great achievements in compensating for the missing functions of the human body. [0003] Prosthetic limbs, also known as "prosthetic limbs", are artificial limbs used by amputees to compensate for partial functions of the missing limbs. There are upper limb prostheses and lower limb prostheses. They are mostly made of aluminum plates, wood, leather, plastics and other materials, and their joints are made of metal parts. For patients with missing lower limbs, wearing lower limb prostheses can fully compensate for the missing functions of the human body, enabling patients to take care of themselves, complete work, and return to soc...
