Description

TECHNICAL FIELD

[0001] The application relates to the field of gear production, and in particular to a gear production article discharging mechanism. BACKGROUND

[0002] A gear refers to a mechanical element with gear teeth on a wheel rim for continuously meshing transmission of motion and power. The application of gears in transmission has appeared very early. In the late 19th century, the principle of generating tooth cutting and special machine tools and cutters for tooth cutting based on the principle appeared successively. With the development of production, the smoothness of gear operation is valued. During the "Tenth Five-Year Plan" period, the Chinese gear industry has developed rapidly: the annual output value of the gear industry in 2005 increased from 24 billion yuan in 2000 to 68.3 billion yuan, with a compound annual growth rate of 23.27%, and has become the largest industry in China's mechanical basic parts. In terms of market demand and production scale, China's gear industry has ranked fourth in the world, surpassing Italy. Gear processing needs a discharging mechanism to facilitate the discharge of gears. The traditional gear production article discharging mechanism often uses a conveying plate to convey and process gears. Since the gears slide down from the top end of the conveying plate at a high speed, the impact force is large when they fall into the collection box, which can easily cause damage to the gears.

[0003] The existing gear production article discharging mechanism with the publication number CN210412896U comprises a supporting bottom plate and a conveying table. The top end of the supporting bottom plate is bolted with a hydraulic cylinder and a second rotating shaft seat. The output end of the hydraulic cylinder is connected with an extension supporting rod. The bottom of the conveying table is bolted with a first rotating shaft seat at the other end. Two hinges are both hingedly connected with a buffer protection plate. The inner side of the buffer protection plate is connected with the end face of a discharging bottom plate through a spiral damping spring. The two ends of the spiral damping spring are both connected with the inner side of the buffer protection plate and the end face of the discharging bottom plate through bolts. When the gears slide down from the top end of the discharging bottom plate, the spiral damping spring can absorb the impact force generated when the gears hit the buffer protection plate, reduce the sliding speed of the gear discharging, avoid damage when falling into the collection box, and at the same time, the inner side of the buffer protection plate is provided with a wear-resistant buffer rubber pad to prevent the gears from being worn and damaged, and ensure the integrity of the gears.

[0004] In view of the above prior art, the inclination angle of the conveying table is adjusted by the hydraulic cylinder, and the buffer protection plate is provided to buffer the gears sliding down. Although the speed of the gear discharging sliding can be reduced, the gears still fall into the collection box when discharging. However, the collection box often has a depth, and the depths of collection boxes of different specifications may be different. Therefore, when the gears directly fall into the collection box, the angle and direction of falling are uncertain, which can still cause damage to the gears, and thus reduce the qualified rate of gear discharging. In order to solve the above problems, the present application provides a gear production article discharging mechanism.

[0005] The above information disclosed in this BACKGROUND section is only for increasing the understanding of the background of the application, and therefore, it can include information that is not prior art known to those of ordinary skill in the art. Utility model content
