Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, specifically a pressure reducing valve body machining center fixture. Background Technology

[0002] As a key component ensuring the safe operation of various equipment, the performance of pressure reducing valves directly affects whether the equipment can operate stably. Therefore, it requires extremely high processing precision. The drilling process, as a core link in the production process, plays a crucial role in it.

[0003] Currently, in the drilling of pressure reducing valves, due to the wide variety of valve specifications and sizes, the conventional clamping devices on ordinary lathes lack flexibility and adaptability. They struggle to achieve stable clamping for valves of different sizes. During drilling, unstable clamping can easily cause the valve to shift or wobble, leading to deviations in the drill bit's position from the intended path. This not only poses a serious safety hazard, potentially causing leakage during subsequent use, but also significantly impacts the overall quality and reliability. Furthermore, when drilling at different positions on the pressure reducing valve, existing lathes typically rely on operators to manually adjust the valve angle. This process is time-consuming and labor-intensive, and manual adjustments are rarely accurate. The complex operating procedures not only significantly reduce production efficiency but also increase the possibility of drilling position deviations, failing to meet current requirements.
