Description

Technical Field

[0001] The utility model relates to the technical field of valve sleeve processing equipment, in particular to a drilling and milling device for valve sleeve processing. Background Art

[0002] The valve sleeve is an important component in the valve. It is located in the center of the valve and plays the role of controlling the fluid flow and pressure. It also plays a sealing role. The main purpose of the valve sleeve is to prevent the valve from leaking air, oil, water, etc., thereby ensuring the normal operation and service life of the valve.

[0003] Valve sleeve drilling and milling is the process of drilling and milling a specific workpiece such as a valve sleeve. In the process of valve sleeve processing, the operator usually uses a handheld drilling and milling machine to drill and mill the valve sleeve. At the same time, the handheld drilling and milling machine also has the characteristics of portability and flexibility.

[0004] In the process of drilling and milling the valve sleeve, although the valve sleeve can be drilled and milled by a handheld drilling and milling machine, for a workpiece such as a valve sleeve, processing accuracy and complexity may be key factors that need to be considered. The handheld drilling and milling machine lacks accuracy and stability, so there may be limitations when performing high-precision or complex processing. Some drilling and milling devices for valve sleeve processing drive the drill and milling cutter to rotate through a driving device, and then the staff presses the rotating operating lever to push the drill and milling cutter downward, thereby making the drill and milling cutter process the valve sleeve. Although this method improves accuracy and stability, the operation is cumbersome. If the operation is improper, it is also easy to cause harm to the staff. For this reason, we propose a drilling and milling device for valve sleeve processing. Utility Model Content
