Obviously, the described embodiments are only the best embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work are within the scope of the present application.

[0019] The present embodiment provides a kind of door handle skeleton embedding tool, as shown in Figure 1 And Figure 2 It includes press fitting platform 4 and multiple press fitting units, multiple processing stations can be provided on press fitting platform 4, to process multiple handle skeletons 3 synchronously, improve processing efficiency, processing station is provided with press fitting unit, press fitting unit can share same control gas path, and multiple processing stations can be completed by one control action Synchronous press fitting;

[0020] In order to facilitate the quick positioning handle skeleton 3, positioning pin is arranged on press fitting platform 4, press fitting unit adopts clamping insert 6 to carry out down press fitting mode, which includes support plate 9 and press fitting mechanism 8, support plate 9 is arranged on press fitting platform 4 by support column, and support column is used as the positioning and assembly adjustment reference of press fitting unit, and press fitting mechanism 8 is installed on support plate 9 by adjusting plate 10;Again with reference to Figure 2 In order to adapt to the embedding of handle skeleton 3 of different size specifications, at least two parallel waist-shaped adjusting holes are formed in adjusting plate 10, since the press fitting points of handle skeleton 3 of different sizes generally have the same size change base point, therefore, with the base point as reference, each mounting point of handle skeleton 3 has corresponding specification change direction, and the waist-shaped adjusting hole is arranged along the change direction;

[0021] According to the distribution of mounting point of handle skeleton 3, press fitting mechanism 8 includes corresponding number and distribution of press fitting cylinders 82, and the press fitting cylinders 82 of multiple press fitting units are connected to the same control gas path to realize linkage press fitting;

[0022] Again with reference to Figure 1, the press-fitting cylinder 82 is provided with a press-fitting rod 81, which is vertically lifted to realize press-fitting under the drive of the press-fitting cylinder 82. In order to facilitate the positioning of the insert 6, the press-fitting rod 81 is provided with a stepped circle at the lower end, and a strong magnetic material ring 84 is fixed on the stepped circle, with the lower end surface located above the lower end surface of the press-fitting rod 81, so as to avoid damage to the strong magnetic material ring 84 under pressure during press-fitting. An integral positioning core rod 85 is formed at the end of the press-fitting rod 81, and the insert 6 is sleeved on the positioning core rod 85. Under the strong magnetic attraction of the strong magnetic material ring 84, the upper end surface of the insert 6 is attached to the lower end surface of the press rod, so as to realize the magnetic clamping and positioning of the insert 6 and provide a press-fitting force during press-fitting. The positioning core rod 85 includes a positioning section and a guide section. The middle hole of the insert 6 is in transition fit with the positioning section. In order to effectively embed and press, the length of the positioning section should be less than the thickness of the insert 6. The guide section is located below the positioning section, and the lower end is in the shape of a sharp cone. A relief hole is formed on the press-fitting platform 4 to accommodate the guide section.

[0023] In the embodiment, the handle skeleton 3 is positioned by the positioning pin, and the press-fitting rod 81 will synchronously take up the handle skeleton 3 under the strong magnetic force adsorption when the press-fitting cylinder 82 is lifted back. Therefore, the press-fitting unit is also provided with a material pressing cylinder 5. Similarly, the material pressing cylinder 5 is arranged on the support plate 9.

At the same time, in order to adapt to the adjustment of the press-fitting mechanism 8, an adaptive hole 711 in the shape of an oblong circle is arranged on the limiting cross rod 71, and the lower end of the limiting sliding rod 72 is fixedly arranged in the adaptive hole 711.
