Description

Technical Field

[0001] The utility model relates to the technical field of riveting, in particular to a horizontal push-type riveting fixture. Background Art

[0002] In the process of product production, it is often necessary to further rivet additional components of the finished casting to meet the requirements of the final product. In the current riveting and riveting process, there is still a considerable amount of manual riveting or semi-automatic riveting. In this mode, the production efficiency is low, and the qualified rate of the finished product cannot be stably maintained at a high level due to human errors. It may also cause accidental injuries to operators, which is not worth the loss.

[0003] Of course, there are also partially automated riveting jigs, which can better cooperate with the loading and unloading devices to complete the riveting action of the product, but there are two common problems. On the one hand, it is difficult to achieve a better positioning effect when facing refined products, which makes it difficult for the finished product to meet the requirements, and the riveting action of some equipment is not stable enough, which further affects the quality of the finished product; on the other hand, this type of automated riveting equipment often requires independent loading and unloading actions, that is, both parties to be riveted need to perform a single loading, positioning after loading, and riveting after positioning. After the riveting action is completed, unloading is performed. The overall action is complicated, resulting in insufficient production efficiency.

[0004] In summary, there is a need for an automated riveting fixture that has a high-precision positioning effect and a stable riveting action, and can minimize loading and unloading, positioning, and riveting actions. Utility Model Content

[0022] 3. The utility model divides the stroke of the push-type riveting cylinder into two stages through the unloading stopper and the unloading cylinder. When the unloading stopper blocks the unloading position, the push-type riveting cylinder performs the first half of the stroke, which completes the riveting of the product. Then, the unloading stopper opens under the action of the unloading cylinder, and the push-type riveting cylinder performs the second half of the stroke to push the product out of the unloading position, thereby integrating riveting and unloading into one action. The same is true for the loading and positioning actions. Positioning is completed during the loading process, which greatly reduces the number of actions of the equipment and further improves production efficiency on the basis of automation.
