Background Technology

This method is very slow and not conducive to mass production. Summary of the Invention

In actual operation, when preparing sensor transmission core wires using transmission wires or fibers, simply clamp the transmission wires or fibers together with the bow-shaped movable clamp assembly and the adjustable lock. Rotating the fine-tuning manual nut causes the spline shaft within the spline shaft seat to straighten the transmission wires or fibers along their two ends. The value of the pre-tension micro-strain required by the specially designed compression spring in front of the thrust ball bearing is determined by the measuring ruler next to it, thus ensuring that the transmission wires or fibers are in a stable tensile state. This clamp is a simple method that ensures stable tensile state of the transmission wires or fibers during standardized mass production of sensor core wire products. Attached Figure Description

[0007] The present invention will now be described in detail with reference to the accompanying drawings: The present invention provides a clamp for eliminating pre-tensioned micro-strain of sensing core wire, comprising a movable clamp assembly, a shaft assembly, a shaft assembly, and a take-up reel assembly.

[0008] See Figure 1 . Figure 2 The movable clamp assembly consists of a vertical central axis 1, a fastening rotating screw 2, a movable clamp 3, an upper convex clamp 4, a lower concave clamp 5, a transmission wire or fiber 6, a working axis 7, a fastening nut 8, a horizontal central axis 9, and an adjustable lock 10. In the actual operation of preparing the transmission wire or fiber 6, simply place the transmission wire or fiber 6 into the lower concave clamp 5 at the working axis 7, position the movable clamp 3 correctly, and fasten the adjustable lock 10. Then, rotate the fastening rotating screw 2 on the movable clamp 3 at the vertical central axis 1. Alternatively, the upper convex clamp 4, under the pressure of the screw pin and the fastening rotating screw 2, clamps the transmission wire or fiber 6 between the upper convex clamp 4 and the lower concave clamp 5, tightly securing it. Finally, the fastening nut 8 at the horizontal central axis 9 secures the fixed base to the spline shaft 12.

[0009] See Figure 1 . Figure 2The shaft assembly consists of shaft seat 11, measuring straightedge 14, and chassis frame 20. Shaft 12 can slide freely within shaft seat 11. The middle part of shaft seat 11 is fastened to measuring straightedge 14 and take-up reel bracket 19 with bolts. The bottom of shaft seat 11 is fastened to chassis frame 20 with bolts. The bottom of shaft seat 11 can be adjusted to the required axial position on the long groove of chassis frame 20 as needed using bolts.

[0010] See Figure 1 . Figure 2 The shaft assembly consists of shaft 12, compression spring 13, thrust ball bearing 15, and fine-tuning manual nut 16. Shaft 12 can slide freely axially within shaft seat 11. Compression spring 13 is mounted outside shaft 12, contacting shaft seat 11 and thrust ball bearing 15 on both sides. Thrust ball bearing 15 is mounted outside shaft 12, contacting compression spring 13 and fine-tuning manual nut 16 on both sides. Fine-tuning manual nut 16 is rotatably mounted on the tail end of shaft 12, with one end contacting thrust ball bearing 15. A bow-shaped movable clamp assembly is used to clamp the transmission wire or fiber. After filament 6, rotate the fine-tuning manual nut 16. At this time, the shaft 12 moves axially within the splined bearing 11 to straighten the transmission wire or fiber filament 6. Then, continue to rotate the fine-tuning manual nut 16 to move the shaft 12 axially within the bearing 11. Under the elastic action of the compression spring 13, by simply observing the distance from the thrust ball bearing 15 to the measuring ruler 14, it is possible to completely obtain the stable pre-tensioned micro-strain and the required tensile state of the transmission wire or fiber filament 6 raw material without using instruments.

[0011] See Figure 1 . Figure 2 The take-up reel assembly consists of a manual rotating lever 17, a take-up reel 18, and a take-up reel bracket 19. The take-up reel 18 is mounted on the take-up reel bracket 19 by a shaft pin, and the take-up reel bracket 19 is fastened to the middle of the splined shaft seat 11 by bolts. Under the rotation of the manual rotating lever 17, the take-up reel 18 can rotate clockwise and counterclockwise on the take-up reel bracket 19. The take-up reel 18 is used to coil the transmission wire or fiber filament 6 that extends beyond the bow-shaped movable clamp assembly.

[0012] In one embodiment, the movable clamp 3 is an arc-shaped movable clamp.

[0013] In one embodiment, shaft 12 is a spline shaft.

[0014] In one embodiment, the upper convex chuck 4 is a replaceable upper convex chuck, and the lower concave chuck 5 is a replaceable lower concave chuck.

[0015] This invention discloses a clamp for eliminating pre-tension micro-strain in the preparation of sensor core wires. In actual operation, when preparing sensor transmission core wires using transmission wires or fiber filaments 6 as raw materials, simply clamp the transmission wires or fiber filaments 6 together with the movable clamp assembly and the adjustable lock 10, then rotate the fine-tuning manual nut 16. At this time, the shaft 12, within the shaft seat 11, will straighten the transmission wires or fiber filaments 6 along the direction of the transmission wires or fiber filaments 6 at both ends. The specially designed compression spring 13 in front of the thrust ball bearing 15, according to the measuring ruler 14 beside it, determines the value of the pre-tension micro-strain required by the compression spring 13, thus ensuring that the transmission wires or fiber filaments 6 are in a stable tensile state. This is a clamp that enables sensor core wire products to be produced in standardized mass production, and is both simple and ensures that the transmission wires or fiber filaments 6 are in a stable tensile state.
