[0023] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 3 As shown, the utility model provides a mother-and-child center structure for a ball turning machine, comprising a female positioning part 1 and a male positioning part 2, the female positioning part 1 being plugged into the male positioning part 2; the male positioning part 2 comprising a male positioning column 23 and a thimble 21, the thimble 21 being arranged at one end of the male positioning column 23, and the axes of the two coincide; the female positioning part 1 comprising a female positioning column 11, the female positioning column 11 being provided with a socket 16 matching the thimble 21; the material has been processed with a through hole before surface processing, and when positioning the material, the material must first be passed through the thimble 21, and the bearing structure of the male positioning part 2 and the female positioning part 1 is adjusted so that the male positioning part 2 and the female positioning part 1 are close to each other, so that the thimble 21 is inserted into the socket 16, and the material is clamped by the male positioning column 23 and the female positioning column 11.

[0025] The male positioning post 23 is provided with a male engaging portion 22 at one end facing the female positioning post 11. The male engaging portion 22 surrounds the circumference of the ejector pin 21 and is composed of a plurality of serrations. After the male positioning post 23 and the female positioning post 11 clamp the material, one end of the material is in close contact with the male engaging portion 22, which can prevent the material from rotating and deviating from the male positioning post 23 during rotation. The specific structure of the male engaging portion 22 is not limited to the serration shape, and can be processed into a scattered anti-slip pattern or other anti-slip pattern according to actual needs, as long as it can play the role of preventing material deflection.

[0026] The male positioning post 23 is provided with a needle seat 25 at one end thereof facing the female positioning post 11. The needle seat 25 is formed with a needle hole for matching the ejector pin 21. After the ejector pin 21 is inserted into the needle hole, it is bonded to the inner wall of the needle hole. The male engaging portion 22 is provided on the end surface of the needle seat 25.

[0027] The female positioning column 11 is provided with a female bite portion 13 at one end facing the male positioning column 23. The female bite portion 13 is a plurality of serrations surrounding the circumference of the insertion hole 16. The female positioning column 11 is provided with a pin portion 14 at one end facing the male positioning column 23. The insertion hole 16 passes through the ejector pin 21 portion 14 and extends into the female positioning column 11. The female bite portion 13 has the same function as the male bite portion 22. After clamping the material, the two ends of the material can be fixed respectively by the male bite portion 22 and the female bite portion 13, thereby preventing the material from deflecting between the female positioning column 11 and the male positioning column 23 during material processing, thereby improving the stability of material processing.

[0028] The female positioning column 11 is provided with a leakage hole 12 on the circumferential surface thereof, and the leakage hole 12 is communicated with the insertion hole 16. When the material is positioned, some material powder will remain inside the through hole processed on the material. In the process of the ejector pin 21 passing through the through hole, the powder will be concentrated at the end of the ejector pin 21 and may enter the insertion hole 16 with the ejector pin 21. If too much powder is pushed into the insertion hole 16, the effective depth of the insertion hole 16 may be reduced during the process of the ejector pin 21 being inserted into the insertion hole 16, resulting in the ejector pin 21 being unable to be fully inserted into the insertion hole 16, causing the ejector pin 21 to bend or unable to clamp the material. After the leakage hole 12 is provided, the powder entering the insertion hole 16 can enter the leakage hole 12 and be thrown out during the rotation of the female positioning column 11, thereby avoiding blockage of the insertion hole 16. The leakage hole 12 is a through hole that passes through the female positioning column 11, and the powder inside the through hole can be thrown out to both sides, thereby having a better anti-blocking effect. A single-sided blind hole can also achieve the above effect.

[0029] A male limit platform 24 is formed on the surface of the male positioning column 23, and the male limit platform 24 is coaxial with the male positioning column 23, and the diameter of the male limit platform 24 is larger than that of the male positioning column 23; a female limit platform 15 is formed on the surface of the female positioning column 11, and the female limit platform 15 is coaxial with the female positioning column 11, and the diameter of the female limit platform 15 is larger than that of the female positioning column 11. During the installation process, the male positioning column 23 and the female positioning column 11 need to be installed on the bearing structure respectively. After setting the male limit platform 24 and the female limit platform 15, they can be used to identify the installation position and play a role in assisting installation positioning.

[0030] By adopting the above structure, positioning can be completed by inserting pins and utilizing the holes processed on the beads themselves. There is no need to manually adjust the material position during the positioning process. Compared with the traditional clamp, which requires manual pinching of the material until the positioning is completed before releasing the fingers, the positioning efficiency of the bead material to be processed can be greatly improved; when positioning the material, it is only necessary to thread it on the ejector pin 21, and there is no need to manually adjust the clamp to clamp the material before releasing the fingers. After the traditional clamp is installed, the clamp needs to be adjusted to clamp the material before the fingers can be released. In this process, the fingers are easily damaged after colliding with the clamp. Therefore, this structure is safer than the traditional clamp.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
