Detailed ways

Referring to Figures 1-3, the invention proposes a new material development and introduction assembly jig, which includes: a base 1 and a limiting column 2, wherein: the material of the base 1 is an acrylic plate, and the material of the limiting column 2 is polyether ether. Ketone, polyetheretherketone is a plastic material with high wear resistance, self-lubrication, mechanical properties and processing stability. The combined structure of the base 1 made of acrylic material and the limiting column 2 made of polyetheretherketone achieves a long service life that acrylic material does not have, while ensuring the controllability of the jig processing cost and meeting the requirements of assembly jig processing. The precision greatly reduces the cost of fixture preparation.

The base 1 is preset with a placement area in the shape of a mobile phone cover and a number of positioning holes 3 arranged in sequence along the edge of the placement area.

There are multiple limiting posts 2, and each limiting post 2 is inserted into each positioning hole 3 one by one, and its top is higher than the upper surface of the base 1 to prevent the mobile phone cover in the restricted placement area from moving. Ensure that the mobile phone cover is in a stable position within the placement area. In order to increase the contact area between the limiting column 2 and the peripheral wall of the mobile phone cover, this embodiment also provides a radial section 4 on the side wall of the limiting column 2 that is higher than the base 1, and all the limiting columns 2 are The radial sections 4 all face the placement area.

Specifically: the positioning hole 3 includes an upper hole segment with a circular cross-sectional shape and a lower hole segment with a regular quadrilateral cross-sectional shape, and the diameter of the inscribed circle formed by the lower hole segment is smaller than the inner diameter of the upper hole segment. The limiting column 2 includes a middle section 21 whose cross-sectional shape matches the upper hole section and is located in the upper hole section, a polygonal column section 22 whose cross-sectional shape matches the lower hole section and is located in the lower hole section, and is higher than the surface of the base 1 and has a limiting section 23 with a radial section 4 . The design of this structure makes the limiting post 2 directional and will not rotate when cooperated with the positioning hole 3, and the connection between the upper hole section and the lower hole section forms a limit that can prevent the middle section 21 from entering the lower hole section. position, so that the limiting column 2 can quickly complete the directional assembly.

In addition, in this embodiment, in this embodiment, the connecting surface of the limiting section 23 and the middle section 21 is flush with the upper surface of the base 1, and the lower edge of the radial section 4 is located where the limiting section 23 and the middle section 21 meet. on the surface, so that the lower edge of the radial cut surface 4 is also in the same plane as the base 1.

Embodiment 4-5, refer to the figure, the cross-sectional shapes of the upper hole section and the lower hole section are both quadrangular, and the diameter of the upper hole section is larger than the diameter of the lower hole section, and there are multiple positioning pins on the base 1 that can be screwed in and out. 5. Each positioning pin 5 corresponds to each limiting column 2 one-to-one, and one end of each positioning pin 5 is screwed radially into the limiting column 2 respectively. When the corresponding limiting column 2 needs to be removed or replaced, the corresponding positioning pin 5 only needs to be unscrewed.

The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technical field can, within the technical scope disclosed in the present invention, implement the technical solutions of the present invention.
