Problems solved by technology

However, when the cross-sectional shape of the workpiece is relatively complex, the design of the cold extrusion die is difficult and costly, so many shaft components with complex shapes are not suitable for the cold extrusion process.

Embodiment Construction

[0022] Please refer to figure 1 and figure 2 As shown, the rotating shaft element according to the first embodiment of the present invention includes a bracket 11 and four first shaft seats 13 .

[0023] The bracket 11 includes a main body 110 , the main body 110 has opposite sides 112 , and arms 114 protrude from two ends of each side 112 . The support arm 114 has an end 115 protruding from the main body 110. The edge of the end 115 has a protruding portion 116 protruding from two opposite edges of the end 115. The end 115 is approximately “T” shaped.

[0024] Please also refer to image 3 As shown, the first shaft seat 13 includes a shaft portion 131 and two clamping arms 132 , and a shaft hole 133 is defined in the center of the shaft portion 131 . The two locking arms 132 are arranged side by side on the shaft edge of the shaft portion 131 , and the locking arms 132 are disposed along the axial direction of the shaft portion 131 . A clamping cavity 134 is defined betw...

Abstract

A rotating shaft element, including a bracket and a shaft seat, with a support arm protruding from one side of the bracket; the shaft seat includes a shaft part and two clamping arms, and the clamping arms are juxtaposed along the axial direction of the shaft part It is arranged on the axial edge of the shaft part, and a clamping cavity is defined between the clamping arms, and the protruding end of the support arm is clamped in the clamping cavity, and the support arm and the clamping The joints of the arms are welded by welding. The invention also provides a manufacturing method of the rotating shaft element.

Description

technical field [0001] The invention relates to a rotating shaft element and a manufacturing method thereof. Background technique [0002] The rotating shaft components used in electronic devices such as mobile phones and personal digital assistants (P7personal Digital Assistant, PDA) require high precision and strength to meet the needs of the mechanical properties of the products. [0003] In the prior art, metal injection molding (Metal Injection Molding, MIM) or precision stamping is usually used to manufacture the rotating shaft element, so as to achieve the required precision and strength. [0004] However, due to design requirements, the shape of the shaft is usually complicated. When the hardness of the rotating shaft is high and the shape is relatively complex, the precision of the product produced by the stamping process is poor, which cannot meet the precision and hardness requirements of the rotating shaft. For the metal injection molding process, many shaft co...
