Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a pin drilling device. Background Art

[0002] The pin is a type of standardized fastener that can be used for static fixed connection or relative movement with the connected parts. It is mainly used for the hinged joint of two parts to form a hinge connection. The pin is usually locked with a cotter pin, which is reliable in operation and easy to disassemble. For example, the patent with publication number CN218946435U discloses a pin drilling positioning device, including a processing table, a drilling machine is arranged on the top of the processing table, a mounting plate is sleeved on the outer side of the drilling machine head, a movable plate is arranged below the mounting plate, four groups of telescopic rods are arranged between the movable plate and the mounting plate, the outer side of the telescopic rod is sleeved with a spring, and the left and right ends of the bottom of the movable plate are each provided with a first fixed block, and the two groups of the first fixed blocks are arranged on the left and right ends of the bottom of the movable plate. A second fixed block and a third fixed block are respectively arranged below the fixed block and on the top of the processing table, a baffle is arranged on the left side of the second fixed block, a fixed plate is arranged on the right side of the third fixed block, and a cylinder is arranged on the right side of the fixed plate. Compared with the existing pin shaft drilling positioning device, this device is provided with a mounting plate on the outer side of the drilling rig head, and a movable plate is installed under the mounting plate, and the pin shaft is fixed by pressing down with a telescopic rod and a spring. Although it can play a certain fixing role, when the pin shaft is small, the spring cannot be compressed to a certain extent, resulting in a small elastic force. Therefore, during the drilling process, the pin shaft drives the spring to be squeezed, which causes the pin shaft to shake, thereby affecting the accuracy of positioning.

[0003] To this end, the utility model provides a pin drilling device. Utility Model Content
