Description

Technical Field

[0001] This utility model belongs to the field of pressure gauge clamping technology, specifically a pressure gauge machining positioning clamp. Background Technology

[0002] A pressure gauge is an instrument used to measure the pressure of fluids (gas, liquid, or steam). It converts pressure into mechanical displacement or electrical signals through elastic elements or sensors to display the pressure value directly. Its applications are extremely widespread, found in almost all industrial processes and scientific research fields. It is ubiquitous in areas such as heat pipe networks, oil and gas transmission, water and gas supply systems, and vehicle repair and maintenance shops. Especially in industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used due to the high mechanical strength and ease of production of their elastic sensing elements. A positioning fixture is a process equipment used to precisely fix the position of workpieces during mechanical manufacturing, assembly, and testing. Its core function is to ensure the positional accuracy and stability of the workpiece during processing or assembly through a positioning and clamping mechanism, thereby improving production efficiency and ensuring product quality. Since pressure gauges require positioning fixtures during processing, a pressure gauge machining positioning fixture is needed.

[0003] Existing pressure gauge machining positioning fixtures have certain drawbacks in use. Pressure gauge machining includes surface deoxidation, sandblasting, and spraying. During machining, the outer wall of the pressure gauge is usually clamped by a clamping mechanism. However, when machining the outer wall of the pressure gauge, the clamping mechanism hinders the machining process, and the clamped part of the outer wall cannot be sprayed in one go. The pressure gauge needs to be disassembled and clamped to other parts for reprocessing, which reduces the machining efficiency of the pressure gauge and the effectiveness of the positioning fixture. Furthermore, multiple machining operations on the outer wall of the pressure gauge will reduce the yield rate of the machined pressure gauge, failing to meet people's needs. Utility Model Content
