[0040] Example

[0041] Reference Figure 1 , a positioning mechanism for bus duct manufacturing and welding, comprising a moving mechanism 10, a welding machine 12, a conveying frame 13 and a positioning mechanism 20;

[0042] The welding machine 12 is placed on the side of the conveying frame 13, wherein the welding machine 12 is used to weld the bus duct, and the moving mechanism 10 is located above the welding machine 12 and the conveying frame 13, wherein the moving mechanism 10 is a common X-axis and Y-axis conveying mechanism, and a hydraulic component 11 is installed on the moving mechanism 10, and the movable part of the hydraulic component 11 is connected to the positioning mechanism 20;

[0043] The above contents can be used to achieve: relying on the positioning mechanism 20 to limit the bus duct, and using the Y-axis transmission mechanism of the moving mechanism 10 to transfer the positioning mechanism 20 and the bus duct to the welding station of the welding machine 12. The transportation to the welding station can ensure the hygiene of the conveying frame 13, and the welding machine 12 can also perform welding work on the two sections of the bus duct.

[0044] Reference Figure 2 The positioning mechanism 20 includes a bearing platform 21, a hydraulic component 210 and a positioning block 211. A pair of hydraulic components 210 are arranged on the bearing platform 21 in a reciprocating telescopic manner. The pair of hydraulic components 210 are distributed in a mirror-image manner. The movable part of the hydraulic component 210 is provided with a positioning block 211. A U-shaped channel 212 is milled on one side of the positioning block 211 that deviates from the hydraulic component 210. A bearing module 22 is rotatably arranged in the U-shaped channel 212. The two adjacent sides of the positioning block 211 close to the hydraulic component 210 are both provided with expansion modules 23.

[0045] Reference Figure 3 and 5 The bearing module 22 includes a first motor 220 and a second motor 223. The first motor 220 and the second motor 223 are both installed on the inner edge of the U-shaped channel 212. The second motor 223 is located below the first motor 220. A first cylindrical sleeve 221 is installed on the moving part of the first motor 220. A curved pad 222 is disposed on the surface of the first cylindrical sleeve 221. A second cylindrical sleeve 224 is installed on the moving part of the motor 223. A bearing frame 1 225 is disposed on the surface of the second cylindrical sleeve 224. A linkage unit 226 is installed at the position of the positioning block 211 close to the U-shaped channel 212. The bearing frame 1 225 is a bending type with a bending angle of 90°. When a section of the bearing frame 1 225 close to the second cylindrical sleeve 224 is consistent with the angle of the positioning block 211, the other end of the bearing frame 1 225 is outside the positioning block 211.

[0046] Reference Figure 4 and 9 The linkage unit 226 includes a telescopic cavity 227, a linkage column 228, a linkage platform 229, an elastic member 2210 and an opener and closer 2211. The telescopic cavity 227 is reserved inside the positioning block 211 near the U-shaped channel 212. A linkage column 228 is provided in the telescopic cavity 227 for telescopic movement. A linkage platform 229 is provided at the position where the linkage column 228 extends into the telescopic cavity 227. An elastic member 2210 is provided between the linkage platform 229 and the inner edge of the telescopic cavity 227. The elastic member 2210 surrounds the surface of the linkage column 228. The opener and closer 2211 is provided on the inner edge of the telescopic cavity 227. An arc-shaped protrusion is provided on the edge of the linkage platform 229 to contact with the opener and closer 2211.

[0047] Through the above content, it can be achieved that: relying on the pair of hydraulic parts 210 to move relative to each other, and the positioning block 211 to move along the radial direction of the hydraulic part 210, it can be applied to bus ducts of different specifications and can ensure the stability of the bus duct during welding;

[0048] When a pair of positioning blocks 211 corresponds to the position of the bus duct, when the whole moves toward the bus duct, the positioning blocks 211 are fitted with the conveying frame 13 at the edge of the bus duct, and the linkage column 228 is acted to move toward the telescopic cavity 227, and the linkage platform 229 touches the shutter 2211, wherein the shutter 2211 is divided into upper, middle and lower sections. When 3232 is in telescopic movement, 3233 touches the upper section of the shutter 2211. At this moment, the motor 223 runs, and the carrier frame 1 225 is made to perform a rotary motion together under the linkage of the second cylindrical sleeve 224, and the movement direction is toward the back of the positioning block 211. After the position stopper 211 limits the edge position of the bus duct, the hydraulic component 210 is used to lift the positioning stopper 211. During the rising process of the positioning stopper 211, the linkage column 228 is no longer in contact with the conveying frame 13. Under the action of the elastic component 2210, the linkage platform 229 and the linkage column 228 are linked to reset. The linkage platform 229 is in contact with the lower section of the opening and closing device 2211. The motor 223 is reset and rotates. The inner edge of the support frame 1 225 can be linked to move toward the direction of the bus duct. The support frame 1 225 supports the bus duct to ensure the stability of the bus duct during welding.

[0049] When the inner edge of the positioning stop 211 touches the edge of the bus duct, the first motor 220 can be driven and the curved pad 222 can be linked to the first cylindrical sleeve 221 to perform a rotary motion. The curved pad 222 moves from bottom to top. The curved pad 222 is made of a rough flexible material. When the curved pad 222 is facing the edge of the bus duct, the resistance between the positioning stop 211 and the bus duct can be increased, and the stability of the bus duct during processing can be further improved. The curved pad 222 can avoid scratching the surface of the bus duct due to its own flexible characteristics.

[0050] Reference Figure 2 and 6 The expansion module 23 includes a second carrier frame 230, a stretching frame 231 and a cross member 232. The second carrier frame 230 is connected to the edge of the positioning block 211. The stretching frame 231 is arranged on the side of the second carrier frame 230 that deviates from the positioning block 211. A plurality of stretching frames 231 are arranged, and a cross member 232 is arranged between the plurality of stretching frames 231. A storage cavity 233 is reserved on the cross member 232, and a telescopic cylinder 234 is arranged in the storage cavity 233. The telescopic cylinder 234 is surrounded by an elastic member 3. A square cylinder 235 is arranged on the telescopic cylinder 234. The square cylinder 235 telescopes in the storage cavity 233. A square column 236 is arranged in the square cylinder 235 relying on the elastic member 1.

[0051] Through the above content, it can be achieved that: when a pair of positioning blocks 211 correspond to the position of the bus duct, when the whole moves toward the bus duct, the positioning blocks 211 fit with the conveying frame 13 at the edge of the bus duct, and the surface of the conveying frame 13 acts on the square tube 235, and the square tube 235 acts on the telescopic tube 234 to move into the storage cavity 233, and when the positioning block 211 approaches the bus duct, the square column 236 touches the edge of the bus duct, and as the positioning block 211 gradually restricts the edge of the bus duct, the square column 236 shrinks to the square tube 235. In the embodiment, when the bus duct is longer, several extension frames 231 will be unfolded under the action of the cross member 232. This is because the specifications of a single positioning block 211 are limited, and the extension and unfolding can be applicable to bus ducts of different lengths. After the positioning mechanism 20 is linked upward, the square cylinder 235 will be separated from the surface of the bus duct under the long-term action of the telescopic cylinder 234. At this time, the square column 236 is reset and located at the lower corner of the bus duct, which provides a load-bearing effect for the bus duct and ensures that the longer bus duct can still maintain a stable effect during welding.

[0052] Reference Figure 2 , 7 8, a limiting module 24 is installed on the opposite surface of a pair of positioning blocks 211, and the limiting module 24 includes a long strip 240, a telescopic seat 241 and a friction protrusion 243. The long strip 240 is installed on the surface of the positioning block 211, and the long strip 240 is distributed in a pair on the positioning block 211, and the pair of long strips 240 are distributed in a mirror image with respect to the U-shaped channel 212. A channel 1 is milled in the long strip 240, and a plurality of telescopic seats 241 are telescopically installed in the channel 1. A friction protrusion 243 is installed on the opposite surface of the telescopic seat 241 on the pair of positioning blocks 211, and an elastic member 242 is installed between the telescopic seat 241 and the channel;

[0053] The above content can be used to achieve the following: when a pair of positioning stops 211 move toward the edge of the bus duct, the bus duct will push the friction protrusion 243 and act on the telescopic seat 241 to enter channel one. When the thickness spacing of the bus duct is small, the friction protrusion 243 in the upper position will limit the upper position of the bus duct, that is, the friction protrusion 243 that is not pushed by the edge of the bus duct can limit the upper position of the bus duct, thereby further improving the stabilizing effect of the bus duct welding, and the friction protrusion 243 pushed by the edge of the bus duct can increase the resistance between the bus duct and the bus duct.

[0054] It should be understood that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but for those of ordinary skill having the benefit of this disclosure, without undue experimentation, the development effort will be a routine task of design, fabrication, and production.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
