[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] EMBODIMENT

[0029] Please refer to Figures 1-6 The present application is a special tooling fixture for processing special steel chain, which comprises a combined fixture. The combined fixture comprises an outer mold 100 for clamping and positioning the special steel chain body 200, and a replaceable inner mold 300. The combined fixture can adapt to the processing requirements of special steel chains of different sizes and types by combining the outer mold 100 and the inner mold 300. The outer mold 100 provides overall structural support to ensure stability during processing. The replaceable inner mold 300 improves the versatility of the fixture to meet the processing requirements of special steel chains of different specifications.

[0030] The outer mold 100 includes a positioning plate 101, an outer ring 102 fixed to the upper side of the positioning plate 101, a support plate 104 fixed to the lower side of the positioning plate 101, and a support leg 103 fixed to the outside of the support plate 104 by fasteners. The support plate 104 has vertically arranged limiting holes for fastener installation on its side. The support leg 103 has a cavity inside to accommodate the support plate 104. The support plate 104 and the support leg 103 form an adjustable support system to assist the external support surface in supporting the fixture. The positioning plate 101 assists in the positioning of the inner mold 300 and, together with the outer ring 102, achieves the positioning of the special steel chain body 200.

[0031] The inner mold 300 includes a mold base 302 embedded inside the positioning plate 101, a template 303 fixed to the upper side of the mold base 302, and a mold core 301 fixed to the upper side of the template 303. The special steel chain body 200 is sleeved on the outside of the mold core 301, and the special steel chain body 200 is located in the inner ring of the outer ring 102. The outer side of the mold core 301 is uniformly provided with anti-slip textures, and the mold core 301 has various sizes. The size of the mold core 301 determines the specifications of the inner mold 300. The integral structure composed of the mold core 301, the mold base 302, and the template 303 is used for internal support of the special steel chain body 200. The anti-slip textures increase the friction between the mold core 301 and the special steel chain body 200, preventing displacement during processing.

[0032] The outer ring 102 has evenly spaced screw holes 102a, and each screw hole 102a is threaded to fit a positioning knob 102b. The inner end of the positioning knob 102b abuts against the outer surface of the special steel chain body 200. The installation position and number of positioning knobs 102b are determined according to the actual positioning requirements. The positioning knobs 102b adopt a simple tightening contact method to achieve rapid positioning of the special steel chain body 200.

[0033] Specifically, the positioning plate 101 has a slot 101a in the middle, which is adapted to the mold base 302. The periphery of the mold core 301 is parallel to the inner side of the outer ring 102. The bottom of the inner wall of the outer ring 102 is in contact with the side of the template 303. The bottom of the template 303 is in contact with the upper side of the positioning plate 101. The slot 101a is used to assist the assembly and positioning of the mold base 302. After the mold base 302 is adapted and installed with the slot 101a, the inner mold 300 and the outer mold 100 maintain a fixed relative position in the horizontal direction. The positional relationship between the template 303, the positioning plate 101, and the outer ring 102 further restricts the position of the inner mold 300.

[0034] Furthermore, the positioning plate 101 has mounting holes at its corners. These mounting holes have internal threads and are connected to the outer mounting surface (such as a machine tool worktable) via fasteners to ensure the stability of the entire fixture during the machining process.

[0035] The operation process of the embodiment is as follows: when the fixture is used for machining the special steel chain, first, the corresponding inner mold 300 is selected according to the specification of the special steel chain body 200 to be machined (the selection of the inner mold 300 is mainly the size of the mold core 301, and the mold core 301 of different specifications corresponds to the special steel chain body 200 of different sizes), and then the inner mold 300 is installed on the positioning plate 101; then, the special steel chain body 200 is sleeved outside the mold core 301 and placed in the inner ring of the outer ring 102; finally, the positioning knob 102b is used to apply appropriate pressure to the special steel chain body 200, so that the special steel chain body 200 is tightly attached to the surface of the mold core 301 and remains stable, and in the subsequent machining process, the special steel chain body 200 can always maintain the correct posture, ensuring the machining quality and efficiency.
