[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] The existing press-fitting equipment cannot ensure the concentricity of the conductive ring core 1 and the conductive ring seat 2 when press-fitting the conductive ring core 1 and the conductive ring seat 2, thereby causing the conductive ring seat 2 and the conductive ring to be cut. How to provide a device that can ensure that the conductive ring core 1 and the conductive ring seat 2 do not deviate and maintain concentricity during the press-fitting process is the main problem that technicians in this field have to solve.

[0032] like Figure 1-3 As shown, the utility model provides a press-fitting tool for press-fitting a conductive ring core 1 and a conductive ring seat 2, the press-fitting tool comprising a support column 3, an elastic component 4 and a positioning component 5, the support column 3 extends along a first direction A, and has a support end 31 at its top for supporting the conductive ring core 1; the elastic component 4 is coaxially sleeved on the bottom of the support column 3, and the elastic component 4 can be telescopic along the first direction A; the positioning component 5 comprises a receiving cavity 514 and an annular groove 513 coaxially arranged with the receiving cavity 514, the receiving cavity 514 is adapted to the support end 31 and the conductive ring core 1, and is used to receive and position the conductive ring core 1, the annular groove 513 is adapted to the convex ring portion at the bottom of the conductive ring seat 2 and is used to position the conductive ring seat 2; wherein the positioning component 5 is coaxially and movably sleeved on the support column 3, the positioning component 5 is in contact with the elastic component 4 and can reciprocate relative to the support column 3 along the first direction A.

[0033] Specifically, the height, diameter and material of the support column 3 can be set according to actual needs, and are not specifically limited here; the top of the support column 3 has a support end 31, and the shape and size of the support end 31 are adapted to the shape and size of the conductive ring core 1, and are used to support the conductive ring core 1. The positioning component 5 is coaxially and movably sleeved on the support column 3, and the positioning component 5 can slide relative to the support column 3 along the first direction A. The positioning component 5 includes a receiving cavity 514 adapted to the conductive ring core 1, and the receiving cavity 514 is adapted to the size of the conductive ring core 1 to limit the horizontal movement of the conductive ring core 1. In addition, the shape and size of the annular groove 513 of the positioning component 5 are set according to the shape and size of the convex ring portion at the bottom of the conductive ring seat 2 that is pressed and installed according to actual needs. The elastic component 4 is coaxially sleeved on the bottom of the support column 3. The bottom of the elastic component 4 is fixed to the bottom of the support column 3 by welding or other fixing methods. The upper end of the elastic component 4 is clamped on the bottom of the positioning component 5. The elastic component 4 can be a spring or other elastic component with a relatively large expansion ratio, so as to provide a longer compression stroke for press-fitting.

[0034] The present invention discloses a press-fitting tool, which includes a support column 3, an elastic component 4 and a positioning component 5. First, the operator places the conductive ring core 1 on the support end 31, and the accommodating cavity 514 accommodates the conductive ring core 1 and limits its moving trajectory, limiting its horizontal movement perpendicular to the first direction A. After that, the operator aligns the bottom convex ring portion of the conductive ring seat 2 with the ring groove 513 of the positioning component 5. After the operator places the conductive ring core 1 and the conductive ring seat 2, the conductive ring core 1 and the conductive ring seat 2 are in an aligned state, that is, a state of maintaining concentricity. When the operator applies a pressure to the conductive ring seat 2 through the pressure head 7, the positioning component 5 transmits the pressure to the elastic component 4 and slides along the first direction A toward the bottom of the support column 3 with the conductive ring seat 2, the elastic component 4 is compressed, and the conductive ring core 1 is pressed into the inner cavity of the conductive ring seat 2, that is, the press-fitting of the conductive ring core 1 and the conductive ring seat 2 is completed. When the pressure disappears, the elastic component 4 stretches from the compressed state along the first direction A due to its own elasticity and quickly recovers its initial state and drives the positioning component 5 to slide toward the top of the support column 3, restoring the initial position of the positioning component 5, so as to place the next conductive ring core 1 and conductive ring seat 2 to be installed. The device positions the conductive ring core 1 and the conductive ring seat 2 respectively through the coaxially arranged support end 31 and the annular groove 513, thereby ensuring the concentricity of the conductive ring core 1 and the wire ring seat 2. The conductive ring core 1 is positioned by accommodating the cavity 514, which can further prevent the conductive ring core 1 and the conductive ring seat 2 from offsetting during the press-fitting process. The elastic component 4 is provided to provide the positioning component 5 with a supporting force to quickly restore the initial state after press-fitting, so as to facilitate the next press-fitting. Therefore, the device has the advantages of high precision and rapid positioning.
