Description

Technical Field

[0001] The invention relates to the technical field of automated drilling equipment, and in particular to automated drilling equipment for mechanical manufacturing. Background Art

[0002] Existing automated drilling equipment in mechanical manufacturing is mainly used for drilling operations on various materials (such as metal, wood, plastic, etc.). For mechanical parts, automated drilling equipment can accurately drill holes for installing bolts, studs and other connectors, and can ensure the positioning accuracy of the drilling.

[0003] However, when it is used, the existing equipment does not have an automated fixing and clamping function. When manually clamping the workpiece, the worker needs to manually operate the fixture, such as tightening screws, adjusting the position of the fixture, etc. This process is relatively cumbersome and time-consuming. Especially in the batch production process, the increase in clamping time each time will accumulate, resulting in a decrease in overall production efficiency. For large-scale production, it will extend the production cycle, and when manual labor is repeatedly clamped, fatigue will inevitably occur, leading to clamping errors. Summary of the invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide an automated drilling device for mechanical manufacturing. When drilling, the workpiece is placed on a sinker plate, and then the lifting plate rises. Under the action of a limit ring and a slide bar, the sinker plate will sink. At this time, the workpiece will drop to the bottom of the through hole and be located below the lifting plate. The lifting plate continues to rise until the limit ring reaches the bottom of the slide bar, and the sinker plate will be driven up. Under the action of the counterweight block, the load-bearing plate will not move. At this time, the upper connecting block will pull the connecting rod upward, and the lower slider will be pulled inward through the connecting rod. The lower slider passes through the sleeve The insert rod will pull the upper slider inward, and the upper slider will push the rubber plate inward to clamp it around the workpiece to fix it until the lower slider touches the stop block. The counterweight block will be driven up, and thus rise as a whole, bringing the workpiece to the bottom of the drill bit for drilling. The workpiece can be automatically sunk and clamped without manual operation of the fixture. Compared with the traditional manual clamping method, the clamping time is shortened, and the entire fixing process is completed automatically. Workers do not need to perform complicated fixture adjustments and workpiece clamping operations, reducing the risk of clamping errors caused by worker fatigue due to long-term repetitive operations.
