[0002] Hydraulic hose is also known as hydraulic oil hose, hydraulic hose, high-pressure hose, hydraulic pipe, steel wire high-pressure hose, wire braided hose and wire spiral hose. It is generally divided into wire braided hydraulic hose and wire spiral hydraulic hose.

[0003] The existing Chinese utility model patent with authorization announcement number CN215981340U discloses a connector for a hydraulic hose, including a connector core, a sleeve and a nut; the connector core and the sleeve are both cylindrical; the sleeve is arranged on the periphery of the connector core; and a nut is movably arranged at one end of the connector core along the axial direction.

[0004] When the above-mentioned hose connector is in use, when processing the hydraulic hose assembly, first put the sleeve 2 onto the outer wall of one end of the hydraulic hose. It does not need to be precisely positioned and can be plugged in. Then insert the joint core 1 into the nut 3, and then insert the hydraulic hose with the sleeve 2 into the end of the joint core 1 where the annular inverted groove 13 is set. Push the hydraulic hose along the axis of the hydraulic hose with force until the tightening ring 12 is pressed against the shoulder groove 14 and the shoulder ring 21 are abutted. The assembly is completed, and the hydraulic hose is inserted into the contraction device. The contraction device is started to extrude the sleeve to complete the processing.

[0005] However, in the actual production process, production personnel found that after the sleeve was squeezed by the shrinking device, the shoulder groove 14 of the joint core and the shoulder ring 21 of the sleeve often could not be tightly pressed together, resulting in failure to pass customer acceptance and affecting the product yield.

[0006] To solve the above problems, the staff carried out innovative design. Summary of the invention

[0007] The purpose of this application is to provide a positioning piece and its positioning tooling and auxiliary tooling. By setting the positioning piece, the joint core can be further positioned when the sleeve is tightened and positioned, thereby effectively ensuring the tight connection between the shoulder groove of the joint core and the shoulder ring of the sleeve after the sleeve is contracted and extruded, thereby ensuring the product qualification rate.
