Abstract
Description
Technical Field
[0001] This utility model relates to a machining device, specifically a material feeding swing arm mechanism. Technical Background
[0002] Slender shafts have wide applications in many technical fields, such as grinding and turning in machining; aerospace, including certain components of aircraft engines and structural parts of spacecraft; and automotive manufacturing, where they can be used in critical components such as engines, transmissions, and steering systems. Induction tempering of slender shafts typically involves scanning quenching, cooling, and then tempering followed by natural cooling. Induction tempering is suitable for mass production of various products. Considering productivity, quenching quality, energy efficiency, and production costs, induction tempering offers significant advantages over traditional furnace tempering.
[0003] For induction tempering of slender shafts, a horizontal continuous quenching machine is typically used. First, the shaft is heated to the quenching temperature, then water-cooled, and then induction-heated to the tempering temperature before being unloaded onto a cooling bed for natural cooling. However, the slender shafts are too long (typically 6 meters), making loading and unloading inconvenient. Existing devices mostly require manual operation to move the workpiece from the loading rack to the roller assembly. This method is inefficient and compromises equipment stability and safety. Therefore, inventing a loading swing arm mechanism would be highly beneficial. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing slender shaft induction tempering equipment by providing a feeding swing arm mechanism, which improves the stability and safety of the equipment, and ultimately increases its efficiency.
[0005] The technical solution of this utility model is implemented as follows: it comprises a drive motor (1), a chain tensioning component (2), a rotating component (3), a swing arm component (4), and a workbench (7). Its features are: the drive motor (1) is fixed on the workbench (7), the drive motor (1) is connected to the rotating component (3) via a chain (5) and a sprocket (6), a bearing seat (3.1) is fixed on the workbench (7), the rotating component (3) is mounted on the bearing seat (3.1) and fixed to the inner ring of the bearing, and several swing arm components (4) are mounted on the rotating component (3), with swing arm forks (4.4) mounted on both sides of the swing arm components (4).
[0006] The preferred technical solution of this utility model is as follows: a chain tensioning component (2) is provided between the chains (5); the rotating component (3) includes a rotating shaft (3.2), a double-row sprocket (3.2) is sleeved on the rotating shaft (3.2), and the double-row sprocket (3.3) is connected to the swing sprocket (8) of the swing arm component (4) through the chain respectively; the swing arm component (4) includes a swing arm bearing (9), a swing arm shaft (10) is fixed inside the swing arm bearing (9), a swing arm fork (4.4) is mounted on the swing arm shaft (10), and a swing arm tensioning sleeve (11) is sleeved between the swing arm shaft (10) and the swing arm fork (4.4).
[0007] The working principle and process of this utility model:
[0008] The drive motor (1) provides power, which drives the rotating component (3) to rotate via a chain and sprocket. The chain tensioning component (2) stabilizes the power output. The tensioning component tightens to stabilize the power output. The rotating component (3) then drives the swing arm component (4) to rotate, but the direction of the swing arm's fork always remains upward, realizing the workpiece transport action from the lower left side to the higher right side.
[0009] This invention has the advantages of simple structure and stable operation, which improves the stability and safety of the equipment and ultimately improves the efficiency of the equipment. Attached Figure Description
