[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Please see Figures 1 to 4 A clamping device with a centering function includes a tooling body 1, in which a receiving groove 11 is provided. Multiple centering mechanisms are spaced apart along the axial direction of the receiving groove 11 on the tooling body 1. Each centering mechanism includes a first clamping plate 2 and a second clamping plate 3 symmetrically arranged on the tooling body 1. A driving member 4 connects the first clamping plate 2 and the second clamping plate 3 to drive them to clamp into the receiving groove 11. A pressing block 5 is provided on the surfaces of the first clamping plate 2 and the second clamping plate 3 facing each other, and the pressing block 5 is opposite to the elastic component of the product. A clearance groove is provided on the tooling body 1 at a position opposite to the pressing block 5. By setting multiple centering mechanisms on the tooling body 1, the tooling body 1 can simultaneously have multiple centering positions, achieving multi-point parallel centering, avoiding product skewing in the tooling body 1, ensuring that the outer shell can be smoothly fitted onto the product, and avoiding scratching with the tooling body 1; and a clamping block 5 is provided on the first clamping plate and the second clamping plate to compress the elastic element on the product during the centering process, so as to avoid the elastic element blocking the fitting of the outer shell.

[0022] Please see Figures 1 to 4 Preferably, the first clamping plate and the second clamping plate are hinged to the tooling body 1. Both the first clamping plate and the second clamping plate have meshing teeth on their outer peripheral surfaces at the hinge point, and the meshing teeth of the first clamping plate and the second clamping plate mesh with each other. The outer peripheral surfaces of the hinge point of the first clamping plate 2 and the second clamping plate 3 are also provided with meshing teeth, which mesh with each other, thus ensuring that the first clamping plate 2 and the second clamping plate 3 rotate synchronously and ensure accurate alignment.

[0023] Please see Figures 1 to 4Preferably, there are two centering mechanisms, with the centering directions of two adjacent centering mechanisms perpendicular to each other, and the planes in which the two centering mechanisms are located are parallel to each other. Having two centering mechanisms with perpendicular centering directions ensures that the axis of the product coincides with the axis of the receiving groove 11; this effectively avoids the problem that a single centering mechanism might result in centering at the centering point, but the product as a whole tilting along that point.

[0024] Please see Figures 1 to 4 Preferably, the tooling body 1 is provided with a number of connecting parts 12 corresponding to the centering mechanism, and the first clamping plate 2 and the second clamping plate 3 of the same centering mechanism are both hinged to the same connecting part 12. Providing the connecting parts 12 facilitates the rapid positioning and installation of the first clamping plate 2 and the second clamping plate 3, and reduces the processing difficulty of the tooling body 1.

[0025] Please see Figures 1 to 4 Preferably, the connecting part 12 is disposed on the outer surface of the tooling body 1, and the connecting parts 12 connecting two adjacent centering mechanisms are respectively located on two adjacent outer surfaces of the tooling body 1. The connecting part 12 can be a fixing block, which can be locked to the outer surface of the tooling body 1 with bolts.

[0026] Please see Figures 1 to 4 Preferably, one end of the first clamping plate 2 and the second clamping plate 3 of the same centering mechanism are both hinged to the connecting part 12, and the driving member 4 is disposed between the other ends of the first clamping plate 2 and the second clamping plate 3 of the same centering mechanism. The tooling body 1 is located in the space surrounded by the first clamping plate 2, the second clamping plate 3, the connecting part 12 and the driving member 4. Of course, the driving member 4 can also be disposed between the extensions extending from the hinge point of one end of the first clamping plate 2 and the second clamping plate 3. The difference from the original solution is that: when the extensions of the first clamping plate 2 and the second clamping plate 3 are gripped and brought closer to each other, the parts of the first clamping plate 2 and the second clamping plate 3 opposite to the tooling body 1 move outward away from the product. When released, the extensions are driven away from each other by the driving member 4, and the parts opposite to the tooling body 1 move inward to clamp the product.

[0027] Please see Figures 1 to 4 Preferably, the driving component 4 is a spring, with one end connected to the first clamping plate 2 and the other end connected to the second clamping plate 3. The driving component 4 is a spring, and upon release, the spring's restoring force can drive the first clamping plate 2 and the second clamping plate 3 to move closer together to clamp the product in the tooling body 1 and achieve centering.

[0028] Please see Figures 1 to 4Preferably, the clamping block 5 is detachably mounted on the first clamping plate 2 or the second clamping plate 3. The clamping block 5 is bolted to the first clamping plate 2 or the second clamping plate 3, and the side of the clamping block 5 facing the product is an arc surface. This facilitates quick replacement of the clamping block 5. The arc surface of the clamping block 5 allows the end face to push open the clamping block 5 during the downward movement of the outer shell, so that the clamping block 5, the first clamping plate 2, and the second clamping plate 3 move outward synchronously around the hinge, making room for the outer shell to smoothly fit into the product.

[0029] Please see Figures 1 to 4 Preferably, the tooling body 1 is fixed to the base 6; the base 6 has a positioning groove on its surface facing the receiving groove 11. This groove serves to limit the position of the product in the axial direction of the receiving groove 11.

[0030] The working principle of this utility model is as follows:

[0031] An external force is applied to the end of the first clamping plate 2 or the second clamping plate 3 furthest from the hinge point. Since the hinge of the first clamping plate 2 and the second clamping plate 3 has meshing teeth, the external force applied to either the first clamping plate 2 or the second clamping plate 3 can cause them to expand outwards synchronously. Then, the product body is inserted into the receiving groove 11 within the tooling body 1. When the external force is released, the first clamping plate 2 and the second clamping plate 3, under the action of the spring, rotate inwards synchronously to clamp the product, ensuring that both sides of the product are subjected to force simultaneously, maintaining a neutral state. Because the surfaces of the first clamping plate 2 and the second clamping plate 3 facing the tooling body 1 have clamping blocks 5, these clamping blocks 5 will clamp the elastic elements on the product body, preventing the outer shell from getting stuck during insertion, thus facilitating insertion. Multiple alignment mechanisms not only prevent multiple elastic elements from getting stuck on the outer shell, but also ensure that the product remains aligned with the axis of the receiving groove 11, guaranteeing accurate alignment.
