Description

TECHNICAL FIELD

[0001] The utility model relates to a riveting equipment especially a feeding mechanism for high-reliability feeding of joint blank on oil pipe joint riveting equipment. BACKGROUND

[0002] The fish-eye joint used on the vehicle models such as motorcycles, sand buggies, off-road vehicles, electric vehicles and bicycles on the market all belong to one of the oil pipe joints, and the existing oil pipe joints of this type will be different according to different vehicle model designs and layout requirements, resulting in certain differences in the used oil pipe joints, mainly divided into straight joints and curved joints. The forming of the existing straight joints or curved joints generally involves 1, separate forming of the joint blank and the core; 2, riveting the formed joint blank and the core; the main difference between the straight joint and the curved joint is that the curved joint involves a bending process after riveting the joint blank and the core.

[0003] In the above process, the existing riveting between the joint blank and the core of the oil pipe joint is generally realized by automatic equipment, that is, the automatic equipment mostly involves two vibration discs for separately placing the joint blank and the core, and two feeding tracks connected with the two vibration discs respectively, specifically: feeding through the two feeding tracks respectively, and then riveting at the intersection;

[0004] In addition, the existing automatic equipment for riveting between the joint blank and the core of the oil pipe joint on the market involves setting a limiting piece for clamping the discharged joint blank on the side close to the joint blank in the specific riveting process, wherein the limiting piece is driven by a cylinder or the like, and the clamping of the joint blank is realized by the extension or retraction of the limiting piece on the side facing the joint blank (the limiting piece is shaped like a long U-shaped groove opened on one end of a metal plate for clamping the joint blank, and the part between the "fish eye" of the joint blank and the joint is clamped by the two sides of the groove).

[0005] The core is pushed to one side of the riveting head of the riveting equipment by the pusher, and when the pusher pushes out the core, the joint blank is clamped at the position of the limiting piece at the same time, and then the riveting head moves towards the joint blank to realize the riveting of the core on the joint blank.

[0006] However, when the above-mentioned automated equipment is used to rivet the joint blank and the core, the following situations may occur in some cases: 1. The U-shaped edge of the long U-shaped groove of the limiting part will directly hit the workpiece, and there is a certain probability that the U-shaped edge will be directly broken; 2. The long U-shaped groove of the limiting part does not fit the joint blank, resulting in material leakage, that is, in the finished product area, some of the formed oil pipe joints will appear, which are joint blanks that have not yet been riveted to the core.

The servo drive source performs a servo driving action to perform a rotational feeding action one by one on the multiple feed positions located on the blank feeding area, and the feeding position that has formed the feeding is rotated toward the riveting area to form a feeding action before riveting; the servo drive source is a servo motor, and the rotating feeding mechanism is a divider.

[0009] The present invention is further configured such that the rotating feeding mechanism also includes a multi-station turntable and a positioning mechanism distributed on one side of the multi-station turntable. The plurality of feeding positions are circumferentially and evenly distributed on the outer edge of the multi-station turntable. The positioning mechanism includes a positioning portion close to the outer edge of the multi-station turntable. The positioning portion is distributed in the area between the blank loading area and the blanking area for blanking of formed parts on the external riveting equipment, and is used to prevent material from falling on the feeding position where the joint blank has been loaded.

[0010] The utility model is further configured such that the positioning portion is an arc surface that matches the curvature of the outer edge of the multi-station turntable.
