Detailed implementation manners

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] It should be noted that all the expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two entities or parameters with the same name but different, and it can be seen that "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present invention. This will not be elaborated one by one in the subsequent embodiments.

[0026] The directional and positional terms mentioned in the present invention, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "top", "bottom", "side", etc., are only with reference to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding the present invention, rather than limiting the protection scope of the present invention.

[0027] As Figures 1-5 shown, it is an embodiment of a component hot riveting welding machine in a circuit breaker of the present invention, including a workbench 1, a work panel 2, a first transmission mechanism 3 arranged on the workbench 1, and a turntable 21 rotatably arranged outside the work panel 2. Refer to Figures 1-2 , the arc striking piece flipping and adjusting mechanism 12 includes a third air cylinder 121 horizontally fixed on the workbench 1 and a vertically arranged fourth air cylinder 122 connected to the third air cylinder 121. The bottom of the fourth air cylinder 122 is connected with a second motor 123 through a track. The second motor 123 is connected with a flipping block 124. Two flipping arms 125 driven by air cylinders are symmetrically arranged at the end of the flipping block 124, and are used for flipping the arc striking piece and feeding it into the third clamping assembly 8. The third air cylinder 121 and the fourth air cylinder 122 drive the up-and-down and horizontal movement of the flipping block 124. The flipping arms 125 are controlled to open and close by air cylinders. After the arc striking piece and the terminal assembly are welded, the pressing claw 72 is lifted. After the flipping arms 125 clamp the arc striking piece, the second clamping block 62 in the first clamping assembly 6 withdraws. The flipping arms 125 retreat, leaving enough space to drive the flipping block 124 to rotate the arc striking piece through the second motor 123. After flipping is completed, the arc striking piece is fed into the third clamping assembly 8 for clamping. The arc striking piece flipping and adjusting mechanism 12 further includes a first clamping assembly 6, a second clamping assembly 7, and a third clamping assembly 8 fixed on the turntable 21.

[0028] A sixth abutting block 126 for abutting against the arc striking piece and fixed on the second motor 123 is arranged between the flipping arms 125; a supporting block 127 fixed on the flipping block 124 is arranged on the other side of the flipping arms 125. The supporting block 127 includes a supporting table 1271 abutting against the side wall of the terminal assembly and a supporting extension block 1272 arranged at the bottom of the supporting table 1271 and abutting against the bottom of the terminal assembly. When the arc striking piece is flipped, the terminal assembly will flip along with the arc striking piece. The arranged fifth abutting block 85 helps to limit the arc striking piece, avoiding excessive clamping by the flipping arms 125 and causing deformation of the arc striking piece. At the same time, the supporting table 1271 and the supporting extension block 1272 hold the terminal assembly, avoiding the terminal assembly being suspended and causing problems such as connection breakage between the terminal assembly and the arc striking piece.

[0029] Refer to Figure 1 and Figures 6-8, the first clamping component 6 is used to clamp the arc starting piece. The two ends of the first clamping component 6 are respectively provided with a second clamping component 7 for clamping the terminal component and a third clamping component 8 for clamping the bimetal component. The first clamping component 6, the second clamping component 7 and the third clamping component 8 are all arranged on the turntable 21.

[0030] Refer to Figures 1-8 , the first clamping component 6 includes a first clamping block 61 fixed on the base 5 and a second clamping block 62 that can be horizontally moved driven by a cylinder. The bottom of the first clamping block 61 is inclined for fitting with the arc starting piece. The second clamping block 62 is provided with a clamping jaw 63 for abutting against the bottom of the arc starting piece. The clamping jaw 63 is located below the first clamping block 61. When installing the arc starting piece, after the arc starting piece is conveyed to the corresponding position, it fits with the inclined bottom of the first clamping block 61. The second clamping block 62 moves towards the first clamping block 61 driven by the cylinder, and abuts against the bottom of the arc starting piece through the clamping jaw 63 to form a fixation. The number of clamping jaws 63 can be set to multiple, and the shape can also be set according to the shape of the arc starting piece to ensure the stability of clamping the arc starting piece.

[0031] The second clamping component 7 includes a terminal slot 71 arranged on one side of the first clamping component 6. Above the terminal slot 71, there is a pressing jaw 72 that can be moved up and down driven by a cylinder. The terminal slot 71 includes a horizontal plate 73 fixed on the base 5 and an L-shaped terminal abutting block 74 fixed on the horizontal plate 73. The terminal abutting block 74 includes a placement groove 75 for placing the flexible connecting copper wire in the terminal component. When installing the terminal component, the bottom is placed on the horizontal plate 73, the front end and the side wall of the terminal component abut against the terminal abutting block 74, and the flexible connecting copper wire is placed in the placement groove 75. The pressing jaw 72 fixes the top of the terminal component, facilitating welding with the arc starting piece and preventing the flexible connecting copper wire from shifting.

[0032] The third clamping assembly 8 includes a first abutting block 81 disposed on the other side of the first clamping assembly 6 and used for abutting against the bottom surface of the bimetal sheet, and a second abutting block 82 used for abutting against one outer wall of the bimetal sheet. Opposite to the second abutting block 82, there is a third abutting block 83 used for abutting against the other outer wall of the bimetal sheet. Below the third abutting block 83, there is a fourth abutting block 84 used for abutting against the arc ignition sheet. The third abutting block 83 and the fourth abutting block 84 are slidably disposed on the base 5 through a cylinder. The first abutting block 81 is fixed between the second abutting block 82 and the third abutting block 83. On the first abutting block 81, there is a fifth abutting block 85 used for supporting the bottom of the bimetal sheet. The second abutting block 82 and the fourth abutting block 84 are provided with receiving grooves 86 for accommodating the flipped arc ignition sheet. The third abutting block 83 is provided with a limiting claw 87 for abutting against the top of the bimetal sheet. The third clamping assembly 8 is used for clamping the arc ignition sheet and the bimetal assembly for welding. During use, the flipped arc ignition sheet is clamped by the horizontally moving fourth abutting block 84 and the second abutting block 82, and the excess part extends into the receiving groove 86. The bimetal sheet in the bimetal assembly is placed on the first abutting block 81, with the bottom abutted against the fifth abutting block 85, and both sides are clamped by the horizontally moving third abutting block 83 and the second abutting block 82. The limiting claw 87 abuts against the top of the bimetal sheet to prevent the bimetal sheet from warping and affecting the welding quality. Other components in the bimetal assembly are placed on the first abutting block 81 and the first clamping assembly 6. In order to avoid scratching the soft connection copper wire in the bimetal assembly, the top of the first clamping block 61 is provided with an inclined surface, which can ensure the integrity of the soft connection copper wire in the bimetal assembly during subsequent discharging.

Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
