[0006] In the above-mentioned auxiliary clamping jaws applied to the hydraulic chuck, the standard hydraulic jaws and the auxiliary jaws are both provided with three, and the standard hydraulic jaws are provided with two mounting holes for connection.

[0007] In the above-mentioned auxiliary clamping jaws applied to the hydraulic chuck, each of the auxiliary jaws is arranged in a square structure as a whole, and the standard hydraulic jaws can be arranged in a square structure or in a trapezoidal structure.

[0008] In the above-mentioned auxiliary clamping jaw used for hydraulic chuck, the upper end of the auxiliary jaw is provided with an installation groove for installing a positioning member, the auxiliary jaw is provided with a plurality of installation holes 2 matching the standard hydraulic jaws, and the positioning member and the sliding member are provided with installation holes 3.

[0009] In the above-mentioned auxiliary clamping jaw applied to a hydraulic chuck, the standard hydraulic jaw is fixedly mounted on the auxiliary jaw by means of fixing bolts, and the auxiliary jaw is fixedly mounted on the sliding member by means of fixing bolts.

[0010] Compared with the prior art, the auxiliary jaws used in the hydraulic chuck are arranged on the auxiliary jaws through standard hydraulic jaws, and multiple products of different sizes can be clamped using only standard hydraulic jaws. The scope of use is wider, the stability of product clamping and the reuse rate of standard hydraulic jaws are increased, and the cost is greatly saved. BRIEF DESCRIPTION OF THE DRAWINGS
