[0021] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0022] As Figures 1-3As shown, the embodiment of the present application provides a metal ring press mechanism, which comprises a press column 1 for pressing the metal ring 3 and a connecting column 2 for connecting with an external driving mechanism, the press column 1 is connected with the connecting column 2, one end of the press column 1 away from the connecting column 2 is provided with a press head 11 matched with the metal ring 3, a magnet 12 for sucking the metal ring 3 and a pressing assembly 13 for pressing the assembled product are slidably arranged in the press column 1, the press column 1 is provided with a first accommodating groove 14 for the magnet 12 and the pressing assembly 13 to move up and down and a second accommodating groove 15 for the pressing assembly 13 to move up and down, the diameter of the second accommodating groove 15 is smaller than that of the first accommodating groove 14.

[0023] Specifically, one end of the press column 1 is connected with the connecting column 2, the connecting column 2 is connected with the external driving mechanism, when the metal ring 3 is manually installed on the press head 11 of the press column 1, the magnet 12 in the first accommodating groove 14 of the press column 1 adsorbs the metal ring 3, the driving mechanism drives the press column 1 to move towards the product, and the metal ring 3 is pressed on the mounting column of the product, the mounting column of the product extends into the first accommodating groove 14 of the press column 1 to lift the magnet 12 and the pressing assembly 13, the magnet 12 releases the metal ring 3, and the pressing assembly 13 buffers and presses the product. When the metal ring 3 is pressed on the mounting column of the product, the driving mechanism drives the press column 1 to move upwards and separates from the product and the metal ring 3.

[0024] In the above structure, by arranging the magnet 12 in the press column 1, the adsorption and feeding of the metal ring 3 by the press head 11 are realized, and the pressing efficiency of the metal ring 3 is improved. By arranging the pressing assembly 13, the buffering and pressing operation of the product is realized, and the pressing accuracy of the metal ring 3 and the mounting column of the product is improved. By arranging the magnet 12 and the pressing assembly 13 in the press column 1, the occupied space of the press mechanism is greatly saved. The metal ring press mechanism not only has a simple structure and small occupied space, but also can be directly used for pressing in a limited space.

[0025] As Figures 2-4As shown in the drawings, in one of the embodiments, the pressing assembly 13 of the metal ring press mechanism includes a sliding shaft 131 and a spring 132. The one end of the sliding shaft 131 is provided with a step 133 which is in sliding fit with the first accommodating groove 14. The other end of the sliding shaft 131 extends into the second accommodating groove 15 through the first recess. The spring 132 is sleeved on the sliding shaft 131. One end of the spring 132 abuts against the step 133, and the other end of the spring 132 abuts against the first accommodating groove 14. When the driving mechanism drives the riveting column 1 to rivet the metal ring 3 on the mounting column of the product, the mounting column of the product extends into the first accommodating groove 14 of the riveting column 1 to lift the magnet 12 and the pressing assembly 13. The sliding shaft 131 of the pressing assembly 13 moves towards the second accommodating groove 15. The step 133 of the sliding shaft 131 compresses the spring 132. The spring 132 abuts against the first accommodating groove 14 to provide a counterforce to the sliding shaft 131, so that the sliding shaft 131 is pressed on the product. This arrangement facilitates the buffering and pressing of the product during the riveting process, and prevents the product from loosening during the riveting process.

[0026] As shown in the drawings, Figure 1 and Figure 3 As shown in the drawings, in one of the embodiments, the one end of the sliding shaft 131 of the metal ring press mechanism is provided with a limiting column 134. Two limiting through holes 16 are symmetrically arranged on the riveting column 1 to limit the movement stroke of the sliding shaft 131. The two ends of the limiting column 134 extend into the two limiting through holes 16 and are in sliding fit with the two limiting through holes 16. When the mounting column of the product extends into the first accommodating groove 14, the magnet 12 and the sliding shaft 131 are lifted. The sliding shaft 131 moves towards the second accommodating groove 15 under the force. The limiting column 134 on the sliding shaft 131 moves along the two limiting through holes 16. The limiting through holes 16 limit the movement stroke of the limiting column 134 and the sliding shaft 131. This arrangement facilitates the limiting of the movement stroke of the sliding shaft 131, and prevents the sliding shaft 131 from moving excessively.

[0027] As shown in the drawings, Figure 2 As shown in the drawings, in one of the embodiments, the connecting column 2 of the metal ring press mechanism is provided with a plurality of connecting holes 21 which are connected with the external driving mechanism. Three connecting holes 21 are arranged on the connecting column 2, and the three connecting holes 21 are connected with the externally arranged mounting holes. This arrangement facilitates the mounting of the connecting column 2 on the external driving mechanism.

[0028] As shown in the drawings, Figure 1 As shown in the drawings, in one of the embodiments, the riveting column 1 of the metal ring press mechanism is in a cylindrical structure, and the connecting column 2 is in a rectangular structure. The rectangular connecting column 2 facilitates the connection of the connecting column 2. The cylindrical riveting column 1 facilitates the positioning fit with the metal ring 3.

[0029] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model.
