Problems solved by technology

However, the current rivets are not easy to realize automatic assembly, resulting in the inability to play the role of fine-tuning and fastening. Secondly, the direction of the cam cannot be effectively adjusted, so that the mechanical properties that the rivet should have cannot be achieved.

Embodiment Construction

[0016] refer to figure 1 and figure 2 , an eccentric cam rivet, comprising a first cylindrical head 10, a second cylindrical head 20 is affixed to the lower part of the first cylindrical head 10, a nail rod 30 is affixed to the lower part of the second cylindrical head 20, the eccentric cam rivet It is made of carbon steel by multi-position cold heading. In this way, the eccentric cam rivet is easy to realize automatic assembly and has good mechanical properties.

[0017] The first cylindrical head 10 and the second cylindrical head 20 are connected in a non-axial structure, the first cylindrical head 10 and the nail rod 30 are in a coaxial structure, and the end of the first cylindrical head 10 is opened There is a tightening groove 80, the tightening groove 80 of the head of the eccentric cam rivet is formed by upsetting for many times with a special punching die, the shank 30 of the eccentric cam rivet is formed by upsetting the combined main mold, and the rivet formed b...

Abstract

The invention discloses an eccentric cam rivet which comprises a first column head. The lower portion of the first column head is fixedly connected with a second column head, and the lower portion of the second column head is fixedly connected with a nail rod; the first column head and the second column head are connected in a differential-axis structure manner, and the first column head and the nail rod are connected in a coaxial structure manner; and a screwing groove is formed in the end of the first column head, and the thickness of the first column head is larger than that of the second column head. The eccentric cam rivet can be automatically assembled easily, is good in mechanical property, has the fine adjusting and fastening function and can effectively adjust the direction of a cam to control the operating speed of the cam.

Description

technical field [0001] The invention relates to an eccentric cam rivet. Background technique [0002] A rivet is a nail-shaped object with a cap at one end and a fastener with a shank structure at the other end. In riveting, the riveted parts are connected by their own deformation or interference, mainly connecting two parts (or components) with through holes. . There are many types of rivets, here we mainly talk about eccentric cam rivets, also known as cam rivets. [0003] Eccentric cam rivets are mainly used on high-end furniture to fine-tune and fasten the gap between metal connectors. With the adjustment of cam rivets, the fit of the gap between metal connectors on high-end furniture can be adjusted to the ideal Scale, enhance the stability of the product; Secondly, the eccentric cam rivet is also used on the transmission rod. When the cam part is in circular motion, the eccentric cam rivet can adjust the direction of the cam, so that the time of the transmission rod ...
