Description

Technical Field

[0001] The utility model relates to the technical field of drilling and tapping devices, in particular to an adjustable multi-head drilling and tapping device. Background Art

[0002] Drilling and tapping devices are devices used to perform drilling and tapping operations on workpieces. Drilling and tapping devices are commonly used in the manufacturing industry to process various metal and non-metal workpieces, such as mechanical parts, automotive parts, aviation parts, etc. They can improve processing efficiency and product quality and reduce manual operations, especially in mass production.

[0003] An existing automatic drilling and tapping device (Announcement No.: CN208099795U) has at least the following disadvantages:

[0004] When the above patent is in use, the rotating frame is controlled by the driving shaft to rotate, and the rotating frame drives the drilling head to rotate. The drilling head can be used to conveniently drill and tap objects on the lifting platform. Since the threaded holes of some flanges are evenly distributed in the circumferential direction of the outer surface of the flange, the drilling machine in the above patent needs to drill holes one by one and then tap. The efficiency of drilling and tapping is too low, which greatly reduces the production efficiency in mass production. Utility Model Content
