Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and more specifically, to an engine cylinder head drilling device. Background Technology

[0002] After the engine cylinder head is cast or forged, key structures such as water passages, oil passages, valve stem holes, and camshaft holes need to be machined using CNC machine tools. Secondly, it features custom hole positions: for special needs, the drilling device can process non-standard hole positions to optimize performance or reduce weight.

[0003] In existing published literature, patent publication number CN221639570U discloses a drilling device for engine cylinder head production. This technology uses a connecting plate with a protrusion fixedly connected to the other end. The protrusion fits into a groove in a track. A first threaded motor drives a first slider slidably mounted on the outside of a first threaded rod to move. The first slider then moves the connecting plate fixedly connected to one side, thereby moving the drill bit back and forth. This allows the drill bit to be adjusted according to the required drilling position when drilling holes in the cylinder head. However, this technology still has the following problems;

[0004] When using an engine cylinder head, a drilling device is required for drilling operations. However, it is difficult to drill holes in different directions according to the position of the engine cylinder head during the drilling process, which results in poor adaptability of the drilling. Therefore, an engine cylinder head drilling device is needed. Utility Model Content
