Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and in particular to a drilling device equipped with an automatic material feeding component. Background Technology

[0002] In the production process of steel pipe fittings, the feeding and drilling equipment, as a core link in automated or semi-automated production, can further improve processing efficiency and reduce the inconsistent processing quality caused by traditional manual drilling compared to traditional manual drilling.

[0003] Chinese patent CN209532192U discloses a loading and unloading device for a drilling machine, which realizes basic automated loading and unloading functions. However, its overall adaptability and accuracy are not high, and it requires regular maintenance. It is not suitable for production environments that require high accuracy and yield.

[0004] Existing equipment is difficult to adapt quickly to pipe fittings of different diameters and lengths. When changing products, a lot of manual adjustment is required. In actual use, insufficient clamping force of the fixture will cause the pipe fitting to shift during processing; excessive clamping force may cause thin-walled pipe fittings to deform. Moreover, when the drill bit penetrates the pipe wall, it will produce severe burrs on the inner wall, which will need to be cleaned afterward. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a drilling device equipped with an automatic feeding component.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a drilling device equipped with an automatic feeding component, including a connecting frame; The connecting frame is provided with a set of transmission grooves, and each transmission groove is provided with a conveying block for connecting the transmission guide rail. The bottom of the transmission guide rail is provided with a docking seat, which is snapped into one side of the connecting frame and is provided with an electric drilling mechanism at the top. The connecting frame is provided with a unloading rack located above the transmission guide rail. The unloading rack is equipped with a sliding seat, and the top of the sliding seat is equipped with a telescopic rod connecting to the rotating plate. The outer side of the rotating plate is equipped with a positioning pressure plate for clamping the pipe fittings. The device adapts to different pipe fittings and precisely controls the drilling depth through replaceable limit pads and blocking plates. The automatic separation of the feeding and positioning mechanisms ensures processing accuracy. During unloading, it integrates a hole burr cleaning function to reduce subsequent processes. The internal buffer support structure can effectively prevent the deformation of thin-walled pipe fittings during clamping, thereby improving product quality and production efficiency.

[0007] A further preferred embodiment of this utility model is as follows: a limiting pad is provided on the side of the transmission guide rail near the conveying block, and a plastic pad is provided on the top of the limiting pad. A through groove corresponding to the docking seat position is opened on the side of the transmission guide rail away from the conveying block, and a blocking plate is movably provided inside the through groove. By setting a quickly replaceable limiting pad and combining it with a movable blocking plate, the device can flexibly adapt to the processing of pipe fittings of different specifications.

This can integrate the deburring process into the processing cycle, reduce the safety hazards caused by protruding burrs, and flatten or push off the burrs.

[0013] A further preferred embodiment of this utility model is: a buffer plate is installed at the bottom of the telescopic shaft. The buffer plate is U-shaped and has an elastic pad inside, which is used to press against the inner wall of the pipe to play a buffering role.

With the adjustable positioning frame and buffer end block, it can accurately position pipe fittings of different sizes, effectively prevent drilling errors caused by pipe fitting size fluctuations or position offsets, ensure the consistency of processing hole positions, and lay the foundation for realizing continuous automated production. This invention uses a dual-motor drive to expand the elastic ring frame, so that the buffer grinding block grinds and cleans the edge of the drilled hole before unloading. This integrates the deburring process into the processing cycle, significantly reducing the workload of subsequent separate grinding, and reducing safety hazards and labor costs in the production process. This utility model employs a positioning pressure plate with a buffer clamp and an internal retractable support buffer plate working together. During processing, the arc-shaped buffer clamp can help correct the pipe fitting and prevent tilting. During unloading, the internal buffer plate unfolds to provide support, effectively dispersing the clamping force and avoiding the deformation problem caused by excessive clamping force during the transfer of thin-walled pipe fittings, thus ensuring the finished product quality of the workpiece.
