[0008] As a preferred embodiment, an extrusion spring is wound around the outer peripheral surface of the spiral rod located inside the extrusion seat, and both ends of the extrusion spring are respectively fastened to the extrusion seat and the inner lining sleeve.

[0009] As a preferred embodiment, an annular gasket is further provided on the outer side of the extrusion seat, and the annular gasket is fastened to the extrusion seat via a spiral rod.

[0010] As a preferred embodiment, a positioning core rod is fixedly provided at the center of the body, and the positioning core rod is fixedly connected to the bearing core shaft.

[0011] As a preferred embodiment, hinge seats symmetrically distributed on the left and right are fixedly provided on the upper side of the treatment body, and the bottom end of the bearing seat is fixedly connected to the hinge seat.

[0012] The beneficial effects achieved by the present invention: The present invention aims at the existing metal terminal cutting which mostly adopts the direct cutting method, resulting in stress concentration of the metal terminal during the cutting process, and is also prone to defects such as cracks and burrs. There is an urgent need to develop an elastic locking jig for metal terminal cutting to solve the technical problems of stress relief and crack prevention during the metal terminal cutting process.

The centripetal locking components are connected in sequence by screwing nuts through spiral rods. The extrusion seat, extrusion spring and lining sleeve lock the load-bearing core shaft centripetally. During the cutting process of the metal terminal, the cutting machine cuts off the covering hoop together with the metal terminal. The stress or torque generated by the metal terminal after being compressed is concentrated and released on the covering hoop. The covering hoop is made of wood and is damaged by pressure to protect the metal terminal from stress concentration and cracks. This solves the problem that the existing metal terminals are mostly cut by direct cutting, which leads to stress concentration of the metal terminals during the cutting process and is also prone to defects such as cracks and burrs. It is urgent to develop elastic locking jigs for metal terminal cutting to solve the technical problems of stress relief and crack prevention in the metal terminal cutting process.

[0015] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] like Figure 1As shown, the present invention proposes an elastic locking jig for cutting metal terminals, including a jig body 1, a bearing seat 3 is fixedly arranged above the jig body 1, and the bottom end of the bearing seat 3 is fixedly connected to the jig body 1 through a bearing core shaft 2; a cutting die 4 is co-arranged in the bearing seat 3, a metal terminal 6 is arranged inside the cutting die 4, and symmetrically distributed centripetal locking components are arranged on the left and right sides of the bearing core shaft 2.

[0017] As a preferred embodiment, a covering hoop 5 is further provided inside the cutting die 4 , and the covering hoop 5 covers the outer peripheral surface of the metal terminal 6 .

[0018] As a preferred embodiment, the covering hoop 5 is made of wood.

[0019] As a preferred embodiment, the centripetal locking assembly includes an extrusion seat 11 that is symmetrically distributed on the left and right. A spiral rod 9 is provided in the center of the extrusion seat 11 and passes through it laterally. An inner lining sleeve 8 is fixedly provided on the inner side of the spiral rod 9. The inner end of the inner lining sleeve 8 is in contact with the outer surface of the load-bearing core shaft 2. A screw nut 13 is fixedly provided on the outer end of the spiral rod 9. The screw nut 13 is connected to the extrusion seat 11 through the spiral rod 9.

[0020] As a preferred embodiment, an extrusion spring 10 is wound around the outer peripheral surface of the spiral rod 9 located inside the extrusion seat 11, and both ends of the extrusion spring 10 are tightly connected to the extrusion seat 11 and the liner pressing sleeve 8 respectively.

[0021] As a preferred embodiment, an annular gasket 12 is further provided on the outer side of the extrusion seat 11 , and the annular gasket 12 is fastened to the extrusion seat 11 via a spiral rod 9 .

[0022] As a preferred embodiment, a positioning core rod 7 is fixedly provided at the center of the treatment body 1 , and the positioning core rod 7 is fixedly connected to the bearing core shaft 2 .

[0023] As a preferred embodiment, hinge seats 14 symmetrically distributed on the left and right are fixedly provided on the upper side of the treatment body 1 , and the bottom end of the supporting seat 3 is fixedly connected to the hinge seats 14 .

[0024] The working principle of the present invention is as follows: The present invention is aimed at the existing metal terminal cutting which mostly adopts the direct cutting method, which leads to stress concentration of the metal terminal during the cutting process, and is also prone to defects such as cracks and burrs. There is an urgent need to develop an elastic locking jig for metal terminal cutting to solve the technical problems of stress relief and crack prevention in the metal terminal cutting process. A bearing seat 3 is connected to the body 1 through a bearing core shaft 2, and a cutting die 4 is placed in the bearing seat 3. The metal terminal 6 to be cut is wrapped with a wooden covering hoop 5 inside the cutting die 4. At the same time, symmetrically distributed centripetal locking components are designed on the left and right sides of the bearing core shaft 2. The centripetal locking component is connected in sequence to the extrusion die 1 through a screw rod 9 by twisting the nut 13. The pressure seat 11, the extrusion spring 10, and the inner lining pressure sleeve 8 centripetally lock the load-bearing core shaft 2. During the cutting process of the metal terminal 6, the cutting machine cuts off the covering hoop 5 together with the metal terminal 6. The stress or torque generated by the metal terminal 6 after being compressed is concentrated and released on the covering hoop 5. The covering hoop 5 is made of wood and is damaged by pressure to achieve defect protection for the metal terminal 6 against stress concentration and cracks. This solves the problem that the existing metal terminals are mostly cut by direct cutting, which leads to stress concentration of the metal terminals during the cutting process and is also prone to defects such as cracks and burrs. It is urgent to develop an elastic locking jig for metal terminal cutting to solve the technical problems of stress relief and crack prevention during the cutting process of the metal terminals.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
