Description

Technical Field

[0001] This utility model relates to the technical field of nut processing equipment, and in particular to an automatic nut tapping device. Background Technology

[0002] In general, automatic tapping of nuts involves tapping the nuts one by one with a single tapping head. This is obviously not very efficient. In addition, while a large number of automatic taps may increase efficiency, the accuracy of the machining process will be reduced accordingly.

[0003] Chinese Patent Publication No. CN221910135U, authorized on October 29, 2024, discloses a nut tapping device with anti-chip-splashing capability, relating to the technical field of nut tapping equipment. It aims to solve the problem of chip-splashing during existing machining processes causing injury and affecting machining accuracy. The device includes a base, a column at the rear of the base, a tapping head vertically slidably connected to the column, a tap at the bottom of the tapping head, a machining table on the base, and a turntable rotatably connected to the machining table. The turntable has evenly spaced positioning grooves along its edge. A cylinder is mounted on the column, and a push block is located on the telescopic section of the cylinder. A cover is located on the front of the push block. This invention uses the cylinder to push the cover onto the top surface of the machining table, effectively capturing and intercepting metal chips generated by the tap's rotation, preventing chip-splashing and injury to operators, and avoiding interference with machining accuracy. This significantly improves the safety and quality of the machining process, reduces safety hazards caused by metal chip-splashing, and ensures machining accuracy. The shortcomings of this invention are insufficient machining efficiency and inadequate alignment accuracy during machining. Utility Model Content
