[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0027] Example 1

[0028] like Figures 1 to 4 As shown, a circuit breaker component assembly hot riveting device is used for riveting a circuit breaker 3, and is provided with a positioning seat 1 and a hot riveting mechanism 2. The hot riveting mechanism 2 is provided with a hot riveting head 21 and a punching mechanism 22. The hot riveting head 21 is movably provided above the positioning seat 1, and the punching mechanism 22 is used to drive the hot riveting head 21 to move; the hot riveting head 21 is provided with a heating rod 211 and a shaping die sleeve 212, and the heating rod 211 is provided at the center of the shaping die sleeve 212.

[0029] The circuit breaker 3 is placed on the positioning seat 1, and the stamping mechanism 22 is used to drive the hot rivet head 21 to move downward until the part to be riveted enters the shaping die sleeve 212. The heating rod 211 heats the riveted part so that it melts into the shape inside the positioning die sleeve 212, making the connection firm and not easy to fall off.

[0030] The stamping mechanism 22 is provided with a stamping cylinder 221 and an air pump 222. The stamping cylinder 221 is provided with a stamping cylinder barrel 2211 and a stamping piston 2212. A stamping air path 223 is provided between the air pump 222 and the inner cavity of the stamping cylinder barrel 2211. The air pump 222 is used to drive the stamping piston 2212 to move and control the moving speed of the stamping piston 2212. The hot rivet head 21 is linked to the stamping piston 2212.

[0031] When the hot rivet head 21 is away from the circuit breaker 3, the air pump 222 pushes the hot rivet head 21 linked with the punching piston 2212 to move downward at high speed; when approaching the hot rivet head 21, the hot rivet head 21 slows down and keeps pressing down at a slow speed; this can not only shorten the riveting time and improve the assembly efficiency, but also ensure that the hot rivet head 21 and the circuit breaker 3 will not be damaged due to impact.

[0032] The punching gas path 223 includes a first gas path 2231 and a second gas path 2232 . The gas transmission speeds of the first gas path 2231 and the second gas path 2232 are different.

[0033] The hot riveting mechanism 2 is also equipped with a temperature sensor 23, which is located in the positioning die sleeve 212. If the temperature in the setting die sleeve 212 is too high, the part to be riveted will melt, become wire-drawn, or even burn. If the temperature in the setting die sleeve 212 is too low, the part to be riveted will deform slowly or slightly. The temperature sensor 23 is used to monitor the temperature in the positioning die sleeve 212 and maintain a moderate temperature in the positioning die sleeve 212 by precisely controlling the operating power and time of the heating rod 211.

[0034] There are two hot riveting heads 21. The number of hot riveting heads 21 can be adjusted according to the needs of workpiece production to improve production efficiency.

[0035] A slide 11 and a slide rail 12 are also provided. The slide 11 is movably arranged on the slide rail 12 ; the positioning seat 1 is linked to the slide 11 .

[0036] A pushing cylinder 13 is also provided, and the slide 11 is linked with the piston of the pushing cylinder 13 to realize automatic transportation and positioning of the circuit breaker 1.

[0037] Example 2

[0038] Figure 5 A second embodiment of a circuit breaker component assembly hot riveting device is shown. The second embodiment of the circuit breaker component assembly hot riveting device is substantially the same as that of Example 1, and the similarities are not repeated here. The differences are that the inner cavity of the stamping cylinder 2211 is provided with an upper cavity 22111 and a lower cavity 22112 that are interconnected. The upper cavity 22111 and the lower cavity 22112 are both cylindrical, and the bottom surface size of the upper cavity 22111 is smaller than the bottom surface size of the lower cavity 22112. The stamping piston 2212 is provided with an upper portion 22121 and a lower portion 22122 that are both cylindrical. The shape of the upper portion 22121 matches that of the upper cavity 22111, and the bottom surface shape of the lower portion 22122 is the same as that of the lower cavity 22112. The stamping air path 223 is connected to the top of the upper cavity 22111.

[0039] The air pump 222 pushes the hot rivet head 21 linked with the punching piston 2212 to move downward. Without changing the gas flow rate, before the upper part 22121 slides out of the upper cavity 22111, the hot rivet head 21 moves downward at a fast speed; after the upper part 22121 slides out of the upper cavity 22111, the hot rivet head 21 moves downward at a slow speed.

[0040] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the scope of protection of the present application.
