Description

Technical Field

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

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems, with functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems, from the simplest shut-off valves to various valves used in extremely complex automatic control systems, have a wide variety of varieties and specifications. During the production process of the valve, it is necessary to open a hole at the end of the valve body to facilitate the fixed connection between the valve and the pipe end. Therefore, a drilling device is required to process the valve during the production and processing of the valve.

[0003] Existing drilling devices for valve production usually use a clamp to fix the valve, and then use a drilling device to perform the drilling work. However, the hole opening positions of different valves are not the same. Therefore, it is necessary to frequently adjust the relative position between the clamp and the drill bit during use, and the operation is relatively cumbersome. It is true that there are some drilling devices that can automatically adjust the hole opening position, but the cost of use is usually high. Therefore, in view of the above problem, a drilling device for valve production is proposed. Utility Model Content
