Description

Technical Field

[0001] The invention relates to the technical field of chain processing, in particular to an automatic assembly machine for D-shaped pins for welding chains. Background Art

[0002] The D-shaped pin for welding chains is a specially designed pin primarily used for connecting and securing chains. This is particularly true in welding chain systems that must withstand heavy loads or special operating conditions. Due to its unique shape and structure, the D-shaped pin offers improved connection strength and stability, making it suitable for applications requiring high safety.

[0003] The traditional D-shaped pin has complicated steps during installation and is very likely to affect the installation quality. Summary of the Invention

[0004] (1) Technical problems solved In view of the shortcomings of the existing technology, the present invention provides an automatic assembly machine for D-shaped pins for welding chains, which solves the problem that the traditional D-shaped pins have complicated steps and are easily affected by the installation quality during the installation process.

[0005] (2) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: A D-shaped pin automatic assembly machine for a welding chain, comprising a feeding rack, a feeding rack, a pushing rod and a fixed rack, the tails of the fixed rack and the feeding rack are connected and vertically distributed, a discharge tray is provided at the connection position of the tails of the fixed rack and the feeding rack, a discharge slot is provided at the inner bottom of the discharge tray, two feed channels are provided on the side wall of the discharge tray, the positions of the two feed channels are symmetrically distributed about the center position of the discharge tray, the two feed channels pass through the side wall of the discharge tray, the feeding rack is fixedly connected to a mounting plate near the side wall of the discharge tray, the mounting plate is fixedly connected to a propulsion head near the side wall of the discharge tray, and the propulsion head is controlled by a sensor.

[0006] Preferably, the inner bottom of the discharge slot is inlaid with multiple strong magnets.

[0007] Preferably, two mounting racks are installed on the top of the unloading rack, and a plurality of adsorption hydraulic presses are installed on the bottom of the two mounting racks.

[0008] Preferably, a push rod is installed inside the fixing frame.

[0009] Working principle: When in use, the D-shaped pin to be installed is loaded through the loading rack. When the D-shaped pin passes the tail of the fixed rack, the push rod will push the material into the discharge channel on the side wall of the discharge tray, and the position of the material will be limited by a strong magnet. At this time, the discharge tray will rotate to align the discharge channel with the unloading rack. When the sensor at the pushing head recognizes the big head of the D-shaped pin, it will push the material into the unloading rack. As the unloading rack is transported, when it passes under the first mounting rack, it will be installed through the adsorption hydraulic press to pre-install the D-shaped pin. When it passes under the second mounting rack, the second set of adsorption hydraulic machines will perform the final installation. This mechanism can merge the original three processes, which significantly improves efficiency and the assembled chain is of good quality.

[0010] (3) Beneficial effects The present invention provides an automatic assembly machine for D-shaped pins for welding chains. It has the following beneficial effects: This welding chain uses an automatic assembly machine for D-shaped pins. When the sensor at the push head identifies the large end of the D-shaped pin, it will push the material into the unloading rack. As the unloading rack is transported, when it passes under the first mounting rack, it will be installed by an adsorption hydraulic press to pre-install the D-shaped pin. When it passes under the second mounting rack, the second set of adsorption hydraulic machines will perform the final installation. This mechanism can merge the original three processes, significantly improving efficiency and ensuring that the assembled chain is of good quality. BRIEF DESCRIPTION OF THE DRAWINGS
