[0041] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0042] The utility model provides a hot riveting device, which is used for riveting a structure to be riveted in an operating system of a circuit breaker, wherein the structure to be riveted comprises a riveting plate 100 and a bracket 200, wherein the bracket 200 is provided with a rivet column 201, and the riveting plate 100 is provided with a rivet hole, wherein the rivet column 201 is penetrated into the rivet hole to complete the pre-installation of the bracket 200 and the riveted plate 100, and the pre-installed bracket 200 and the riveted plate 100 are arranged in a carrier 300 to facilitate riveting.

[0043] like Figure 1-Figure 7 As shown, the hot riveting device includes a hot riveting mechanism 1 and a supporting mechanism 2. The carrier 300 moves the pre-installed bracket 200 and the riveted plate 100 along the conveying direction of the structure to be riveted to the top of the supporting mechanism 2. The supporting mechanism 2 is used to support the carrier 300 to support the bracket 200. The hot riveting mechanism 1 is pressed against the rivet column 201 to perform riveting and forming on the rivet column 201.

[0044] The hot riveting mechanism 1 includes a driving component 11 and a hot riveting component 12. The hot riveting component 12 includes a hot riveting mounting member 121, a rivet shaft 122 and a heating member 123. The rivet shaft 122 and the heating member 123 are both arranged on the hot riveting mounting member 121. The heating member 123 can generate heat to heat the hot riveting mounting member 121. The hot riveting mounting member 121 can transfer heat to the rivet shaft 122 so that the rivet shaft 122 reaches a set temperature. The driving component 11 can drive the hot riveting mounting member 121 to drive the rivet shaft 122 to move so that the rivet shaft 122 abuts against the rivet column 201, and the rivet shaft 122 is riveted and formed to achieve hot riveting connection between the bracket 200 and the riveted plate 100. It can be understood that since the rivet shaft 122 has a set temperature, when the rivet shaft 122 abuts against the rivet column 201, the end of the rivet column 201 can be softened to form a riveted portion, the operation is simple, and the forming effect is good.

[0045] The support mechanism 2 includes a support driving member 21, a push block 22 and a top block 23. The push block 22 is fixedly arranged at the output end of the support driving member 21. The top block 23 and the push block 22 are slidably abutted, and the top block 23 and the push block 22 are arranged at an angle. The support driving member 21 can drive the push block 22 to move along a first direction, and the push block 22 pushes the top block 23 to generate displacement in a second direction. A support block 232 is arranged on the top block 23, so that the top block 23 supports the carrier 300 through the support block 232, that is, the support of the bracket 200 is achieved; it should be noted that the first direction is the output direction of the output end of the support driving member 21, and the second direction and the first direction are arranged perpendicular to each other; the support mechanism 2 enables the top block 23 to decompose the force of the rivet shaft 122 pressing the rivet column 201 into the first direction and the second direction when supporting the bracket 200, so as to reduce the force acting on the support driving member 21, thereby reducing the requirements for the support driving member 21, and can effectively reduce the damage to the support driving member 21. In this embodiment, the first direction is the X-axis, the second direction is the Y-axis, and the first direction and the second direction are perpendicular to each other.

[0046] In other embodiments, the first direction and the second direction are different directions and may not be perpendicular to each other.

[0047] The hot riveting device realizes the automatic hot riveting connection between the bracket 200 and the riveted plate 100, and abuts against the end of the rivet column 201 through the rivet shaft 122, so that the end of the rivet column 201 is quickly softened to form a riveted portion. The operation is simple and reliable, and the forming effect is good; the support mechanism 2 supports the bracket 200, can provide a higher load-bearing capacity for the bracket 200, and improve the service life of the support drive member 21.

[0048] Optionally, a profiling groove 1221 is provided at one end of the rivet shaft 122 away from the hot riveting mounting piece 121. The rivet shaft 122 abuts against the rivet column 201 through the profiling groove 1221, which can soften the end of the rivet column 201 to form a riveted portion with the same shape as the profiling groove 1221, thereby improving the molding effect of the rivet column 201 and improving the aesthetics and firmness.

[0049] Optionally, at least one of the push block 22 and the top block 23 is provided with an inclined surface, and the other one of the two slides and abuts on the inclined surface so that the top block 23 and the push block 22 are set at an angle. In this structure, one of the push block 22 and the top block 23 abuts against the inclined surface, so that when the push block 22 moves along the first direction, it can push the top block 23 to generate displacement in the second direction.

[0050] For example, only the push block 22 is provided with the first inclined surface 221, and the top block 23 slides against the first inclined surface 221; or only the top block 23 is provided with the second inclined surface 231, and the push block 22 slides against the second inclined surface 231. Both of the above structures can realize that the push block 22 pushes the top block 23 to move.

[0051] Preferably, refer to Figure 5 A first inclined surface 221 is provided on one end of the push block 22 that slides against the top block 23, and a second inclined surface 231 is provided on one end of the top block 23 that slides against the push block 22. The first inclined surface 221 and the second inclined surface 231 slide against each other. This structure enables the support driving member 21 to drive the push block 22 to move in the first direction. Due to the sliding abutment between the first inclined surface 221 and the second inclined surface 231, the push block 22 pushes the top block 23 to move more smoothly, thereby reducing the wear between the parts and improving the service life.

[0052] Optionally, the push block 22 is further provided with an extension portion 222 , and when the push block 22 retracts to the initial position, the top block 23 can abut against the extension surface of the extension portion 222 to prevent the first inclined surface 221 and the second inclined surface 231 from sliding off and causing failure.

[0053] Further, refer to Figure 6 The support mechanism 2 also includes a sliding mounting seat 24, which is provided with a first sliding groove and a second sliding groove that are interconnected. The push block 22 and the top block 23 are slidably arranged in the first sliding groove and the second sliding groove respectively, and the first inclined surface 221 of the push block 22 and the second inclined surface 231 of the top block 23 are slidably abutted. This structure makes the movement of the push block 22 and the top block 23 more stable and improves the bearing capacity.

[0054] In this embodiment, the sliding mounting seat 24 is a right-angle structure, which is provided with a first slide groove and a second slide groove which are vertically connected to each other. The first slide groove extends along the first direction, and the second slide groove extends along the second direction, that is, the top block 23 and the push block 22 are arranged at an angle of 90°; of course, in other embodiments, the top block 23 and the push block 22 may not be vertical, as long as the push block 22 can push the top block 23 to move along the second direction when it moves along the first direction.

[0055] In some embodiments, the support mechanism 2 further includes a bottom mounting seat 26 , and the sliding mounting seat 24 and the support driving member 21 are fixedly disposed on the bottom mounting seat 26 .

[0056] In some embodiments, in order to enable the top block 23 to return to its original position quickly, the support mechanism 2 also includes an elastic member 25, the two ends of which are respectively connected to the top block 23 and the sliding mounting seat 24. After the support driving member 21 drives the push block 22 to move the top block 23, the top block 23 stretches the elastic member 25. After the support driving member 21 drives the push block 22 to retreat, the top block 23 can return to its original position under the action of the elastic member 25.

[0057] Optionally, the elastic member 25 may be a spring.

[0058] In one embodiment, the elastic member 25 can be arranged on the outer side of the sliding mounting seat 24, and the outer side of the sliding mounting seat 24 and the top block 23 are both provided with hanging screws, and the two ends of the elastic member 25 are respectively connected to the two hanging screws, so that the installation is convenient; or, in another embodiment, the elastic member 25 can be hidden in the sliding mounting seat 24, and a groove can be opened in the sliding mounting seat 24, and the groove wall of the groove and the top block 23 are also provided with hanging screws. The elastic member 25 is located in the groove, and the two ends of the elastic member 25 are respectively connected to the two hanging screws to prevent the elastic member 25 from occupying the external space and avoiding interference with other components, and the structure is more compact.

[0059] like Figure 7As shown, in order to prevent more heat from being transferred to the driving component 11 and thus causing the driving component 11 to overheat, the hot riveting mechanism 1 also includes a connecting frame 13, which is connected between the driving component 11 and the hot riveting mounting member 121. Specifically, the connecting frame 13 includes a large connecting plate 131, two small connecting plates 132 and two connecting rods 133. The two small connecting plates 132 are respectively connected to the large connecting plate 131 through the two connecting rods 133. The large connecting plate 131 is fixedly connected to the driving component 11, and the two small connecting plates 132 are respectively fixedly connected to the two ends of the hot riveting mounting member 121. Since the small connecting plates 132 are fixedly connected to the hot riveting mounting member 121, The contact surface area of ​​1 is small, that is, the sum of the contact surface areas of the two small connecting plates 132 and the heat riveting mounting piece 121 is smaller than the upper surface area of ​​the heat riveting mounting piece 121, and the length of the connecting rod 133 is long, and the heat on the heat riveting mounting piece 121 is transferred to the small connecting plate 132, and then transferred to the large connecting plate 131 through the connecting rod 133, and then transferred to the drive component 11 through the large connecting plate 131, which reduces the heat transfer and dissipates the heat faster, effectively preventing the drive component 11 from overheating and affecting the service life of the parts, and effectively preventing the drive component 11 from overheating and causing scalding accidents, and the connecting frame 13 has a strong bearing capacity.

[0060] In other embodiments, the large connecting plates 131 may also be configured as two small connecting plates 132 respectively fixedly connected to the connecting rods 133, so that the connecting frame 13 forms two I-shaped brackets, which can further prevent excessive heat from being transferred to the drive component 11, thereby preventing the drive component 11 from overheating and causing scalding accidents.

[0061] The hot riveting mounting part 121 includes a fixed plate 1211 and an adjusting mounting part. Two small connecting plates 132 are fixedly connected to the upper surface of the fixed plate 1211. The sum of the contact surface areas of the two small connecting plates 132 and the fixed plate 1211 is smaller than the upper surface area of ​​the fixed plate 1211. Therefore, it is possible to effectively reduce the heat transfer from the fixed plate 1211 to the driving component 11, effectively prevent the driving component 11 from overheating and affecting the service life of the parts, and effectively prevent the driving component 11 from overheating and causing scalding accidents. The rivet shaft 122 is arranged on the adjusting mounting part, and the adjusting mounting part is connected to the lower surface of the fixed plate 1211, and the adjusting mounting part is adjustable along a first direction. When the carrier 300 is moved into place along the conveying direction of the structure to be riveted, the position of the adjusting mounting part along the first direction can be adjusted so that the rivet shaft 122 on the adjusting mounting part and the rivet column 201 of the bracket 200 on the carrier 300 can be aligned, thereby improving practicality. In this embodiment, the conveying direction of the structure to be riveted is the Z axis, and the conveying direction of the structure to be riveted is perpendicular to the first direction.

[0062] Further, refer to Figure 7 Combined with Figure 3 or Figure 4As shown, the adjustment mounting member includes an adjustment plate 1213 and a connecting block 1214. The heating member 123 is a heating rod that is inserted into a heating hole on the connecting block 1214. The connecting block 1214 is provided with a stepped hole. An annular limiting portion 1222 is provided at one end of the rivet shaft 122 that is away from the profiling groove 1221. The rivet shaft 122 is inserted into the stepped hole, and the annular limiting portion 1222 is limited on the stepped surface of the stepped hole. One end face of the adjustment plate 1213 is fixedly connected to the connecting block 1214 and abuts against the stepped hole. Pressed on the rivet shaft 122, the adjustment plate 1213 can abut and limit the rivet shaft 122, and is used to withstand the reaction force when the rivet shaft 122 presses the rivet column 201. This structure makes the rivet shaft 122 easy to install and has high installation accuracy, which can ensure long-term use; the other end surface of the adjustment plate 1213 is adjustably connected to the fixed plate 1211 along the first direction to achieve the rivet shaft 122 adjustable along the first direction, so that the rivet shaft 122 can accurately abut against the rivet column 201.

[0063] Furthermore, if Figure 8-Figure 9 As shown, a track groove is provided on the end surface of the fixed plate 1211 facing the adjusting plate 1213, and a slide rail is provided on the end surface of the adjusting plate 1213 facing the fixed plate 1211. The slide rail and the track groove are slidably connected to realize an adjustably connected adjustment plate 1213 and the fixed plate 1211; the hot riveting mounting member 121 also includes a first locking block 1212 and a locking member, the first locking block 1212 is fixedly connected to the fixed plate 1211, and when the adjustment of the adjusting plate 1213 relative to the fixed plate 1211 is completed, the locking member is passed through the first locking block 1212 and connected to the adjusting mounting member to fix the adjusted adjusting mounting plate to the fixed plate 1211.

[0064] In other embodiments, a slide rail may also be provided on the fixing plate 1211 , and a track groove may be provided on the adjusting plate 1213 .

[0065] The first locking block 1212 is provided with an extension plate, and the extension plate is provided with a U-shaped groove. When the first locking block 1212 is fixedly connected to the fixing plate 1211 by the first standard screw, there is a set interval between the extension plate and the adjustment plate 1213. The locking member includes a locking screw 1215 and a locking nut 1216. The locking screw 1215 is passed through the U-shaped groove and is threadedly connected to the adjustment plate 1213. The locking nut 1216 is threadedly connected to the screw rod of the locking screw 1215. The locking nut 1216 is tightened so that the extension plate is clamped between the locking nut 1216 and the nut of the locking screw 1215 to achieve positioning and fixation of the adjustment plate 1213.

[0066] In order to further improve the connection firmness between the fixed plate 1211 and the adjusting plate 1213, the hot riveting mounting part 121 also includes a second locking block 1217, which is arranged on one side of the fixed plate 1211 along the conveying direction of the structure to be riveted, and a countersunk hole is arranged on the portion of the second locking block 1217 corresponding to the fixed plate 1211, and a long slot hole is arranged on the portion of the second locking block 1217 corresponding to the adjusting plate 1213, and the long slot hole extends along the first direction, and the second locking block 1217 is connected to the fixed plate 1211 by passing a second standard screw through the countersunk hole, and is also connected to the adjusting plate 1213 by passing a third standard screw through the long slot hole.

[0067] When the rivet shaft 122 needs to be replaced, the first standard screw and the third standard screw can be removed to disassemble the adjustment mounting part, and then the adjustment plate 1213 and the connecting block 1214 can be separated to disassemble and assemble the rivet shaft 122. After installing the new rivet shaft 122, there is no need to adjust the position, and the first standard screw and the third standard screw can be directly installed to achieve quick disassembly and assembly.

[0068] Refer to Figure 7 The driving assembly 11 includes a heat riveting bracket 111, a heat riveting driving member 112 and a heat-insulating sliding member. The heat riveting driving member 112 is fixedly arranged on the heat riveting bracket 111. The heat-insulating sliding member is arranged at the output end of the heat riveting driving member 112, and the heat-insulating sliding member is slidably connected to the heat riveting bracket 111. The two ends of the connecting frame 13 are respectively connected to the heat-insulating sliding member and the fixing plate 1211 of the heat riveting mounting member 121. The structure makes the riveting shaft 122 more stable when moving by arranging the heat-insulating sliding member, and prevents the heat on the connecting frame 13 from continuing to transfer.

[0069] Specifically, the heat-insulating sliding member includes an L-shaped sliding plate 113, a first heat-insulating plate 114 and a second heat-insulating plate 115. The vertical plate 1131 of the L-shaped sliding plate 113 is slidably connected to the heat-riveting bracket 111 through a guide rail slider structure. The first heat-insulating plate 114 and the second heat-insulating plate 115 are respectively fixedly connected to the two sides of the horizontal plate 1132 of the L-shaped sliding plate 113, and the first heat-insulating plate 114 is fixedly connected to the output end of the heat-riveting driving member 112, and the second heat-insulating plate 115 is fixedly connected to the connecting frame 13.
