[0002] In the field of tobacco equipment, the rocker-arm vibrating conveyor has a simple structure, is inexpensive, and can spread the material loosely and evenly. It is widely used in the silk-making workshop of cigarette factories. However, after long-term operation, the rubber rod of the rocker arm loses its function due to wear and looseness, and the vibrating conveyor makes abnormal noises. The rocker arm needs to be disassembled in time, and the rubber rod needs to be pressed back in, and the rocker arm pressing process needs to be completed by a special rocker arm pressing machine.

[0003] In the process of pressing the rocker arm of the existing rocker arm pressing machine, the rocker arm must be accurately placed just above the square slot on the plane of the frame of the rocker arm pressing machine. The existing method is to judge whether the position of the rocker arm is appropriate based on naked eye observation and experience, which easily leads to a large deviation of the rocker arm position on the plane of the frame. The rocker arm pressing block cannot smoothly pass through the square slot during the pressing process and collides with the frame, which easily leads to deformation of the frame and even damage to the rocker arm pressing machine. Therefore, the utility model provides a high-precision positioning device for the rocker arm pressing machine to solve the above-mentioned problems. Utility Model Content
