Description

Technical Field

[0001] The utility model relates to the technical field of strain gauge processing, in particular to a clamping tool for processing a strain gauge with high stability. Background Art

[0002] Strain gauges are sensor devices used to measure surface strain or deformation of an object. They are usually made of metal or semiconductor materials and measure tiny deformations on the surface of the object being measured through resistance, capacitance or inductance. Strain gauges are usually used to measure tiny surface strains of objects, so very high accuracy and stability are required. Using a high-stability processing clamping fixture can ensure that the strain gauge maintains a fixed position and state during the measurement process, avoiding errors or distortion caused by external interference, so a high-stability strain gauge processing clamping fixture is required.

[0003] After searching the Chinese patent document with the announcement number of CN220593049U, a strain gauge processing fixture is disclosed, including a processing table, a strain gauge body is placed on the top of the processing table, a gear is rotatably connected to the middle of the processing table, a rack is slidably connected to the middle of the processing table, the rack is meshed with the gear, a rotating block is fixedly connected to the top of the gear, a positioning block is fixedly connected to the top of the rack, the other end of the positioning block is in contact with the strain gauge body, a fixed rod is fixedly connected to the middle of the processing table, and a movable plate is slidably connected to the middle of the fixed rod. In the utility model, through the cooperation of the gear, positioning block, limit rod, rotating block and other structures, the strain gauge body can be positioned horizontally and vertically, so as to realize the rapid positioning of the strain gauge body, and the strain gauge body is always kept in the middle of the processing table in both the vertical and horizontal directions, which is convenient for the processing equipment to process and improve the work efficiency.
