[0057] This embodiment provides a riveting device for processing a contact assembly of a circuit breaker. Specifically, the riveting device is used for riveting such as Figure 1 and Figure 2 The connecting plate 100 and the arc starting plate 200 of the contact assembly are shown.

[0058] like Figure 2 , Figure 3 and Figure 4 As shown, the riveting device includes a workbench, a driving member, a base plate 1, a mobile positioning mechanism 2 and a riveting mechanism 3, and the base plate 1 is fixed on the workbench. The mobile positioning mechanism 2 includes a limiting base 21 fixedly arranged on the base plate 1, and a mobile positioning member 22 is slidably arranged on the limiting base 21, and a positioning assembly 23 is arranged on the mobile positioning member 22.

The riveting mechanism 3 is arranged on the bottom plate 1 and is placed at one end of the limiting base 21 provided with a riveting position. The driving member is connected to the riveting mechanism 3, and the driving member is used to drive the riveting mechanism 3 to rivet the connecting plate 100 and the arc-starting plate 200 on the positioning assembly 23. The driving member can be a hydraulic press, which is not specifically limited here.

[0059] The base plate 1 is fixedly arranged on the workbench, the riveting mechanism 3 is connected to the driving member, the limiting base 21 of the movable positioning mechanism 2 is fixed on the base plate 1, and a movable positioning member 22 is slidably provided on the limiting base 21. By dragging the movable positioning member 22, the positioning assembly 23 can be moved between the riveting position and the loading position, thereby placing the connecting plate 100 and the arc-starting plate 200 on the positioning assembly 23 at the riveting position or the loading position. At the loading position, the operator places the connecting plate 100 and the arc-starting plate 200 on the positioning assembly 23, and pre-installs the arc-starting plate 200 on the connecting plate 100. At the riveting position, the driving member drives the riveting mechanism 3 to rivet the connecting plate 100 and the arc-starting plate 200 placed at the riveting position, and rivets the arc-starting plate 200 to the connecting plate 100; the first positioning member 231 and the third positioning member 233 of the positioning assembly 23 respectively position the connecting plate 100, and the second positioning member 232 positions the arc-starting plate 200, thereby realizing the positioning of the connecting plate 100 and the arc-starting plate 200. During the riveting process, the connecting plate 100 and the arc-starting plate 200 are connected. The plate 100 and the arc-striking plate 200 will not be displaced; in the process of riveting the connecting plate 100 and the arc-striking plate 200, it is only necessary to drag the movable positioning piece 22 to place the positioning assembly 23 in the loading position or the riveting position, and there is no need to drag the entire riveting device to realize the loading and unloading or riveting of the connecting plate 100 and the arc-striking plate 200, thereby improving the riveting efficiency of the contact assembly, saving time and effort, and when dragging the movable positioning piece 22, the operator's hand will not be placed in the riveting position, and the riveting mechanism 3 will not cause a safety hazard to the personal safety of the operator, thereby improving the safety of the operator's operation.

[0060] Continue to refer to Figure 1 and Figure 2 As shown, the first end of the connecting plate 100 is provided with a first hole 101, the second end of the connecting plate 100 is provided with a second hole 102, the first end of the arc-starting plate 200 is connected to the second end of the connecting plate 100, the second end of the arc-starting plate 200 is bent, and the second end of the arc-starting plate 200 is placed above the second hole 102. According to the structure of the connecting plate 100, in one embodiment, as Figure 5 and Figure 7 As shown, the first positioning member 231 is used to be inserted into the first hole 101 in the first direction, the second positioning member 232 is used to be inserted into the second hole 102 in the first direction and pressed against the second end of the arc-starting plate 200, and the third positioning member 233 is used to limit the connection plate 100 in the second direction. The first positioning member 231, the second positioning member 232 and the third positioning member 233 cooperate to limit the position of the connection plate 100 on the movable positioning member 22 in two directions. In the process of dragging the movable positioning member 22, the connection plate 100 will not be displaced, thereby ensuring the riveting quality of the connection plate 100 and the arc-starting plate 200. In addition, the second positioning member 232 also plays a role in supporting the arc-starting plate 200 upward to prevent the second end of the arc-starting plate 200 from bending and deformation.

[0061] The first direction is the height direction of the connecting plate 100 , and the second direction is the width direction of the connecting plate 100 .

[0062] Optionally, combined Figure 5 and Figure 6 As shown, the first positioning member 231 includes a first positioning column 2311 and a first plug-in column 2312. One end of the first positioning column 2311 is fixed to the first plug-in column 2312, and the other end of the first positioning column 2311 is fixed to the movable positioning member 22. The first positioning column 2311 is used to be inserted into the first hole 101. The outer diameter of the first plug-in column 2312 is smaller than the outer diameter of the first positioning column 2311. The end surface of the first positioning column 2311 can play a role in supporting the connecting plate 100. The first plug-in column 2312 limits the position of the connecting plate 100 to prevent the connecting plate 100 from shaking and affecting the riveting quality. The end of the first plug-in column 2312 is provided with a chamfer so that it can be smoothly inserted into the first hole 101.

[0063] In some other embodiments, the first positioning member 231 is a column with a conical structure. The first positioning member 231 is inserted into the first hole 101. When the outer diameter of the first positioning member 231 is close to the hole diameter of the first hole 101, the connecting plate 100 no longer moves downward, thereby positioning the connecting plate 100.

[0064] The second positioning member 232 includes a second positioning column 2321 and a second plug-in column 2322, one end of the second positioning column 2321 is fixed to the second plug-in column 2322, and the other end of the second positioning column 2321 is fixed to the movable positioning member 22, the second plug-in column 2322 is used to insert the second hole 102 and press against the second end of the arc-starting plate 200, the outer diameter of the second plug-in column 2322 is smaller than the outer diameter of the second positioning column 2321, and the end face of the second positioning column 2321 can support the connecting plate 100, and the second plug-in column 2322 limits the position of the connecting plate 100 to prevent the connecting plate 100 from shaking and affecting the riveting quality. Since the second plug-in column 2322 presses upward against the second end of the arc-striking plate 200, in order to achieve effective support, the end face shape of the second plug-in column 2322 is adapted to the surface shape of the arc-striking plate 200, and the end face of the second plug-in column 2322 is in full contact with the arc-striking plate 200, thereby increasing the contact area between the second plug-in column 2322 and the arc-striking plate 200, thereby increasing the supporting force of the second plug-in column 2322 to support the arc-striking plate 200.

[0065] In some other embodiments, the second positioning member 232 is a column with a conical structure, and the second positioning member 232 is inserted into the second hole 102. When the outer diameter of the second positioning member 232 is close to the hole diameter of the second hole 102, the connecting plate 100 no longer moves downward, thereby limiting the connecting plate 100.

[0066] like Figures 5 to 10As shown, for connecting plates 100 with different structures, third positioning members 233 with different structures are provided.

[0067] In one embodiment, if Figure 2 As shown, the connecting plate 100 includes a connecting plate body 103 with a U-shaped structure, one end of the connecting plate body 103 is bent toward the outside of the connecting plate body 103 to form a first bent plate 104, and the other end of the connecting plate body 103 is bent to form a second bent plate 105. The second bent plate 105 is bent in the same direction as the first bent plate 104. The bottoms of the second bent plate 105, the first bent plate 104 and the connecting plate body 103 are parallel or approximately parallel to each other, the first hole 101 is arranged on the first bent plate 104, and the second hole 102 is arranged on the second bent plate 105. One end of the arc-striking plate 200 is plugged into the second bending plate 105, and the second end of the arc-striking plate 200 is bent in the same direction as the first bending plate 104. A long hole 106 is provided on the connecting plate body 103, and the second positioning piece 232 can pass through the long hole 106 and the second hole 102 in sequence and press against the second end of the arc-striking plate 200.

[0068] Combination Figure 2 , Figure 5 and Figure 6 As shown, for the structure of the above-mentioned connecting plate 100, the first positioning member 231 positions the first bending plate 104, the second positioning member 232 positions the second bending plate 105 and supports the arc-starting plate 200 upward. The third positioning member 233 includes positioning plates 2331, at least two positioning plates 2331 are arranged on the movable positioning member 22 at intervals along the second direction, and the connecting plate 100 is placed between the positioning plates 2331 arranged at intervals, and the arranged positioning plates 2331 limit the position of the connecting plate 100 in the second direction. Specifically, the bottom of the connecting plate body 103 is placed between the positioning plates 2331 arranged at intervals. In summary, based on the structure of the connecting plate 100, in the first direction, the first positioning member 231 and the second positioning member 232 realize the limitation of the upper structure of the connecting plate 100, and the third positioning member 233 realizes the limitation of the lower structure of the connecting plate 100, so as to prevent the connecting plate 100 from moving, tipping or rotating.

[0069] In order to facilitate the connection plate 100 to be placed between the positioning plates 2331, a chamfer is provided on the inner side of the end of each positioning plate 2331. The positioning plate 2331 and the movable positioning member 22 are an integrally formed structure.

[0071] Combination Figure 1 , Figure 7 and Figure 8 As shown, for the structure of the above-mentioned connecting plate 100, the first positioning member 231 positions the first end of the connecting plate 100, and the second positioning member 232 positions the extension plate 107 and supports the arc-starting plate 200 upward. The third positioning member 233 includes a positioning seat 2332, and the first positioning member 231, the second positioning member 232 and the positioning seat 2332 are sequentially arranged on the movable positioning member 22, and the positioning seat 2332 is provided with a positioning groove 2333, and the positioning groove 2333 is used to accommodate the second end of the connecting plate 100. Further optionally, the shape of the inner groove wall of the positioning groove 2333 matches the shape of the second end of the connecting plate 100 to improve the stability of the fixed connecting plate 100. In addition to supporting the second end portion of the connecting plate 100, the positioning seat 2332 also supports a portion of the extension plate 107 upward, but does not affect the second hole 102 provided by the second positioning member 232, thereby avoiding deformation of the extension plate 107. The shape of the surface of the positioning seat 2332 supporting the extension plate 107 can be adapted to the extension plate 107, which is not specifically limited here.

The movable positioning member 22 is also provided with a positioning seat 2332, so as to be suitable for the above-mentioned Figure 1In the second structure of the connecting plate 100 shown, the positioning plate 2331 will not affect the installation of the second connecting plate 100, and the positioning seat 2332 will not affect the installation of the first connecting plate 100. The positioning seat 2332 is fixedly connected to the movable positioning member 22, or the positioning seat 2332 is detachably connected to the movable positioning member 22. When the second structure of the connecting plate 100 needs to be processed, the positioning seat 2332 can be installed.

[0074] Continue to refer to Fig.10 As shown, the movable positioning member 22 is slidably connected with the limiting base 21. In some embodiments, a slide groove 211 is provided on the limiting base 21. The two ends of the slide groove 211 are respectively provided with a riveting position and a loading position. The movable positioning member 22 is slidably arranged in the slide groove 211. A limiting member 212 is provided in the slide groove 211. The limiting member 212 is used to limit the position of the movable positioning member 22 in the slide groove 211 so that the positioning assembly 23 is placed in the riveting position, thereby improving the riveting quality and reducing the defective product rate. Optionally, the side wall of the slide groove 211 close to the loading position is penetrated, and the movable positioning member 22 can slide out or slide in, which is convenient for loading and unloading the connecting plate 100 and the arc-starting plate 200. The limiting member 212 is the side wall of the slide groove 211 close to the riveting position. When the movable positioning member 22 slides against the side wall of the slide groove 211, the positioning assembly 23 is placed in the riveting position. The structure of the limiting member 212 is simple, and no additional parts are required. In some other feasible embodiments, a slide rail is provided on the limiting base 21, a slider is provided on the movable positioning member 22, the slider is slidably provided on the slide rail, and the limiting member is provided on the slide rail, thereby realizing a sliding connection between the movable positioning member 22 and the limiting base 21.

[0075] like Fig. 9 As shown, in order to facilitate the movement of the movable positioning member 22 between the riveting position and the loading position, the movable positioning member 22 includes a movable positioning block 221 and a handle 222. The movable positioning block 221 is slidably connected to the limiting base 21, and the handle 222 is connected to the movable positioning block 221.

The movable positioning block 221 can be an L-shaped structure, the vertical part of the movable positioning block 221 is connected to the handle 222, and the positioning assembly 23 is arranged on the horizontal part of the movable positioning block 221.

[0076] Combination Figure 3 and Fig.11As shown, the riveting mechanism 3 is used to rivet the connecting plate 100 and the arc-starting plate 200 on the positioning assembly 23. In some embodiments, the riveting mechanism 3 includes a top plate 31, a riveting assembly 32 and a pre-pressing assembly 33. The top plate 31 is arranged above the mobile positioning mechanism 2, and the top plate 31 is used to connect with the driving member. The riveting assembly 32 includes a transmission member 321 and a riveting member 322, the transmission member 321 is connected to the top plate 31, the riveting member 322 is located on one side of the limiting base 21, and is slidably arranged on the bottom plate 1 along the second direction, and the transmission member 321 and the riveting member 322 are arranged one by one. The pre-pressing assembly 33 is connected to the top plate 31, and the pre-pressing assembly 33 is arranged above the riveting position. The top plate 31 can move downward along the first direction. Specifically, the top plate 31 is driven by the driving member to move downward along the first direction. The transmission member 321 moves downward along the first direction with the top plate 31. The pre-pressing assembly 33 moves downward and presses against the arc-striking plate 200. The transmission member 321 moves downward and drives the corresponding riveting member 322 to move the riveting member 322 toward the positioning assembly 23 located at the riveting position. The transmission member 321 cooperates with the riveting member 322 to convert the force in the first direction into the force in the second direction. The riveting member 322 is used to rivet the connecting plate 100 and the arc-striking plate 200. At the same time, the pre-pressing component 33 is pressed against the arc-striking plate 200, and the pre-pressing component 33 cooperates with the second positioning member 232 to position the arc-striking plate 200. When the riveting member 322 rivets the connecting plate 100 and the arc-striking plate 200, the arc-striking plate 200 will not be displaced or deformed relative to the connecting plate 100, thereby improving the riveting quality of the connecting plate 100 and the arc-striking plate 200 and reducing the defective rate.

[0077] Optionally, a positioning block 323 and a retaining block 324 are fixedly provided at intervals along the second direction on the base plate 1, the positioning block 323 is arranged close to the limiting base 21, the first end of the riveted member 322 passes through the positioning block 323 for riveting the connecting plate 100 and the arc-starting plate 200, the second end of the riveted member 322 is placed between the positioning block 323 and the retaining block 324, a first elastic member 325 is connected between the second end of the riveted member 322 and the positioning block 323, the second end face of the riveted member 322 is a first inclined surface 3221, the transmission member 321 can be placed between the retaining block 324 and the second end of the riveted member 322, and the transmission member 321 is provided with a second inclined surface 3211 which cooperates with the first inclined surface 3221. The positioning block 323 provides a guide installation for the movement of the riveted component 322. The positioning block 323 and the retaining block 324 cooperate to provide a guide for the movement of the transmission component 321. During the gradual engagement of the second inclined surface 3211 with the first inclined surface 3221, the transmission component 321 moves between the retaining block 324 and the positioning block 323, and one side of the transmission component 321 engages with the retaining block 324, ensuring that the second inclined surface 3211 can stably engage with the first inclined surface 3221 to push the riveted component 322 to move in the second direction toward the positioning assembly 23. During the movement of the riveted component 322 toward the positioning assembly 23, the first elastic component 325 is compressed. When the transmission member 321 moves upward along the first direction, the second inclined surface 3211 gradually separates from the first inclined surface 3221, and the transmission member 321 no longer applies force to the riveting member 322, the first elastic member 325 resets the riveting member 322 and presses against the retaining block 324, and the retaining block 324 also limits the riveting member 322.

[0078] Since both opposite sides of the arc-striking plate 200 need to be riveted to the connecting plate 100, two positioning blocks 323 are provided, and each positioning block 323 is respectively provided with a holding block 324, a riveting member 322 and a transmission member 321. The two positioning blocks 323 are spaced apart in the second direction, and a limiting base 21 is provided between the two positioning blocks 323. The two riveting members 322 move in opposite directions to act on the opposite sides of the arc-striking plate 200, and exert force on the arc-striking plate 200 so that the arc-striking plate 200 is riveted to the connecting plate 100.

[0079] Combination Figure 3 and Fig.12As shown, the pre-pressing assembly 33 is used to position the arc-striking plate 200. Optionally, the pre-pressing assembly 33 includes a fixed block 331 and a pre-pressing block 332. The fixed block 331 is fixedly connected to the top plate 31, one end of the pre-pressing block 332 is slidably connected to the fixed block 331, and the other end of the pre-pressing block 332 is placed above the riveting position and is used to press the arc-striking plate 200. A second elastic member 333 is connected between the pre-pressing block 332 and the fixed block 331. The pre-pressing block 332 is connected to the fixed block 331 through the second elastic member 333. The force applied by the pre-pressing block 332 to the arc-striking plate 200 is a buffer force to prevent the arc-striking plate 200 from being damaged by excessive force applied to the arc-striking plate 200. Further optionally, a through hole is provided on the fixed block 331, and the second elastic member 333 is placed in the through hole, and one end of the second elastic member 333 is connected to the top plate 31, one end of the pre-pressing block 332 is placed in the through hole, and the other end of the second elastic member 333 is connected to one end of the pre-pressing block 332, and the pre-pressing block 332 can move in the through hole. The through hole is provided on the fixed block 331, which provides a guide for the expansion and contraction of the second elastic member 333 and the movement of the pre-pressing block 332, so that the pre-pressing block 332 can be accurately pressed against the arc-starting plate 200.

[0080] Combination Figure 3 and Fig.13 As shown, in order to improve the stability of the top plate 31 moving in the first direction, ensure that the transmission member 321 can stably drive the riveting member 322 to accurately rivet the connecting plate 100 and the arc-starting plate 200, and improve the riveting quality, in some embodiments, a limiting assembly 34 is provided between the top plate 31 and the bottom plate 1, and the limiting assembly 34 is used to ensure that the riveting assembly 32 accurately rivets the connecting plate 100 and the arc-starting plate 200. The limiting assembly 34 includes a positioning column 341 and a guide column 342. The positioning column 341 is fixedly connected to the top plate 31, and the guide column 342 is fixedly connected to the bottom plate 1. A guide sleeve 343 and a limiting post 344 are sleeved on the guide post 342. The guide sleeve 343 is slidably connected to the guide post 342. The limiting post 344 abuts against the bottom plate 1 and is fixedly connected to the guide post 342. The positioning post 341 is slidably sleeved on the outer side of the guide post 342 and is connected to the guide sleeve 343. The limiting post 344 is used to limit the downward displacement of the positioning post 341. The positioning post 341 moves along the axial direction of the guide post 342 under the guidance of the guide sleeve 343 and the guide post 342. When the positioning post 341 contacts the limiting post 344, it indicates that the riveted part 322 is riveted in place, the top plate 31 cannot continue to move downward, and then the transmission part 321 cannot continue to move downward, and the riveted part 322 cannot continue to move toward the positioning assembly 23 in the second direction, which effectively prevents the riveted part 322 from over-riveting the arc-starting plate 200.

[0081] There are multiple groups of limiter assemblies 34, and the multiple groups of limiter assemblies 34 are arranged at intervals along the circumference of the top plate 31. Exemplarily, the top plate 31 and the bottom plate 1 are both rectangular plates, and a group of limiter assemblies 34 are respectively arranged at the four corners of the top plate 31, which not only supports the top plate 31, but also guides the movement of the top plate 31 in the first direction, ensuring that the top plate 31 can move stably.

[0082] Further optionally, the positioning column 341 is connected to the top plate 31 by bolts 345, and a gasket 346 is sleeved on the bolts 345.

[0085] Step 2: The operator starts the driving member, which drives the top plate 31 to move downward in the first direction, so that the second inclined surface 3211 of the transmission member 321 gradually contacts the first inclined surface 3221 of the riveting member 322, and then drives the riveting member 322 to move toward the positioning assembly 23 in the second direction, and the riveting member 322 applies force to the arc-starting plate 200.

[0086] Step 3: When the positioning column 341 moves upward and downward in the first direction and abuts against the limiting column 344 , the riveting process is completed and the arc-starting plate 200 is riveted to the connecting plate 100 .

[0087] Step 4: Control the driving member to drive the top plate 31 to move upward in the first direction, and the riveting member 322 is reset under the action of the first elastic member 325 .

[0088] Step 4, after the top plate 31 is moved into place, the driving member stops working, drags and moves the positioning member 22, places the positioning assembly 23 in the loading position, and the operator takes out the riveted connecting plate 100 and the arc-starting plate 200.
