Description

Technical Field

[0001] The invention relates to the technical field of rotary riveting machines, in particular to a rotary riveting machine with a positioning mechanism. Background Art

[0002] Riveting machine is also called riveting machine, rotary riveting machine, riveting machine and rolling riveting machine. The rotary riveting machine is a new type of riveting equipment developed based on the principle of cold rolling. It refers to mechanical equipment that can rivet objects together with rivets. The equipment has a compact structure, stable performance, and convenient and safe operation.

[0003] When the existing rotary riveting machine is in use, the main body of the rotary riveting machine cannot be moved, which has limitations and is inconvenient to use.

[0004] The existing patent (publication number: CN213701641U) discloses a positioning mechanism for a rotary riveting machine, which is provided with a plurality of trapezoidal grooves on the top of the rotary riveting table. According to the size of the workpiece, the movable block is slid into the trapezoidal groove, and the workpiece is placed on the rotary riveting table. The bottom of the workpiece contacts the rubber damping pad on the top of the slide plate. At the same time, the workpiece presses the slide plate downward and drives the spring to contract. The spring drives the slide plate to provide elastic force upward, and then the screw is rotated so that the screw drives the positioning pressure plate to move downward and position the workpiece. The positioning pressure plate provides pressure downward, and the spring provides elastic force upward. Under the action of the rubber damping pad, the two movable blocks are prevented from moving with the workpiece, thereby ensuring the stability during positioning. The device not only can adjust the position of the workpiece during positioning, which is convenient for positioning workpieces of different sizes, but also provides an upward elastic force to the workpiece through the spring. The rubber damping pad increases the friction between the workpiece and the workpiece, thereby avoiding displacement of the workpiece, ensuring the stability during positioning, and being convenient to use.

[0005] However, the above technical solution still has certain defects. When the main body of the rotary riveting machine is in use, the workpiece is positioned by the movable block, the screw rod and the positioning plate, and then the workpiece is processed by the main body of the rotary riveting machine. When the height of the rotary riveting table needs to be adjusted, the toggle lever needs to be manually rotated, and the toggle lever drives the threaded sleeve to rotate forward and backward, so as to adjust the height of the rotary riveting table. The operation is relatively cumbersome, which increases the workload of the staff, and the main body of the rotary riveting machine cannot be moved, which has limitations in use. Therefore, a rotary riveting machine with a positioning mechanism is proposed. Summary of the invention
