Detailed Embodiment

[0027] The following is combined with the attached Figures 1 - 3Further detailed description is made to this application.

[0028] The embodiment of this application discloses a strip steel welding positioning device for a galvanizing production line.

[0029] A strip steel welding positioning device for a galvanizing production line includes a frame 1, a docking platform 2 and a positioning component 3. The frame 1 is placed on the ground, and a welding device 11 is installed on the frame 1. The welding device 11 is used for welding the tail of the previous strip steel and the head of the next strip steel. The docking platform 2 is fixedly installed at a position on the frame 1 close to the welding device 11, and the docking platform 2 is located below the welding device 11. The positioning component 3 is slidably installed on the top of the docking platform 2. There are two positioning components 3, and the two strip steels correspond to the two positioning components 3 one by one.

[0030] When it is necessary to weld the tail of the previous strip steel and the head of the next strip steel, place the tail of the previous strip steel and the head of the next strip steel on the corresponding positioning component 3, perform positioning and calibration through the corresponding positioning component 3, and then make the two positioning components 3 drive the tail of the previous strip steel and the head of the next strip steel to approach and align with each other.

[0031] A docking groove is opened at the top of the docking platform 2. The length direction of the docking groove is consistent with the length direction of the strip steel, and the docking groove penetrates through both ends of the docking platform 2.

[0032] The positioning component 3 includes a positioning seat 31, a horizontal positioning part 32 and a vertical positioning part 33. The positioning seat 31 is located inside the docking groove, and the positioning seat 31 is slidably matched with the docking groove, and the inner wall of the docking groove guides and limits the positioning seat 31. A positioning hole 311 is opened on the positioning seat 31, and the positioning hole 311 penetrates through both ends of the positioning seat 31.

[0033] A limiting part 312 is further arranged on the vertical outer side wall of the positioning seat 31. The limiting part 312 includes a limiting plate 3122 and a limiting rod 3121. The limiting plate 3122 is fixedly installed on the vertical outer side wall of the positioning seat 31. The limiting rod 3121 is vertically arranged, and the limiting rod 3121 is helically penetrated through the limiting plate 3122. When it is necessary to fix the positioning seat 31 on the docking platform 2 and limit the distance between the two positioning seats 31, rotate the limiting rod 3121 to make the bottom end of the limiting rod 3121 press against the top of the docking platform 2, and limit the positioning seat 31 through the friction force between the bottom end of the limiting rod 3121 and the docking platform 2.

[0034] In order to further improve the convenience of rotating the limiting rod 3121, a rotating ear 3123 is fixedly installed on the top of the limiting rod 3121, and the staff rotates the limiting rod 3121 through the rotating ear 3123. At the same time, in order to further reduce the possibility of the limiting rod 3121 damaging the docking platform 2, an elastic pad 3124 is fixedly installed at the bottom of the limiting rod 3121.

[0035] The horizontal positioning part 32 includes a horizontal fixing block 321, a horizontal sliding block 322 and a horizontal adjusting unit 323.

[0036] Both the horizontal fixing block 321 and the horizontal sliding block 322 are located inside the positioning hole 311 of the positioning seat 31. The horizontal fixing block 321 is fixedly installed on the inner side wall of the positioning hole 311. The horizontal sliding block 322 is in sliding fit with the positioning hole 311. Positioning grooves 3211 for positioning and correcting the strip steel are provided on the sides of the horizontal fixing block 321 and the horizontal sliding block 322 that are close to each other.

[0037] The horizontal adjusting unit 323 includes a sliding rod 3231, an adjusting rod 3234, an adjusting plate 3233, a spring 3232, and a fixing plate 3235.

[0038] One end of the adjusting rod 3234 is fixedly installed on the side of the positioning seat 31 away from the limiting part 312. The adjusting rod 3234 slidably passes through the adjusting plate 3233. The sliding rod 3231 is located on the side of the adjusting plate 3233 close to the positioning seat 31. There are two sliding rods 3231. The two sliding rods 3231 are respectively located at both ends of the adjusting plate 3233. One end of each sliding rod 3231 is fixedly connected to the adjusting plate 3233. The other end of each sliding rod 3231 slidably passes through the positioning seat 31 and is fixedly connected to the horizontal sliding block 322.

[0039] The fixing plate 3235 is located on the side of the adjusting rod 3234 away from the positioning seat 31. The spring 3232 is sleeved on the adjusting rod 3234. One end of the spring 3232 abuts against the adjusting plate 3233, and the other end of the spring 3232 abuts against the fixing plate 3235. When the spring 3232 is in a natural state, the horizontal sliding block 322 abuts against the horizontal fixing block 321.

[0040] When it is necessary to clamp the steel strip, the staff moves the sliding rod 3231 to drive the horizontal sliding block 322 away from the horizontal fixing block 321 through the adjusting plate 3233, and inserts the steel strip into the positioning hole 311. Then, the adjusting plate 3233 is released, so that the sliding rod 3231 drives the horizontal sliding block 322 to move towards the horizontal fixing block 321 under the elastic force of the spring 3232, and the side of the steel strip in the length direction is inserted into the corresponding positioning groove 3211. The inner wall of the positioning groove 3211 positions and corrects the steel strip.

[0041] In order to facilitate the staff to pull the adjusting plate 3233, a pull ring 3236 for the staff to pull is fixedly installed on the adjusting plate 3233.

[0042] The vertical positioning part 33 includes a pressure-bearing block 331, a guide rod 332 and a pressing block 333.

[0043] The pressure-bearing block 331 is fixedly installed on the transverse fixing block 321, and the top of the pressure-bearing block 331 is flush with the bottom of the inner wall of the positioning groove 3211. The guide rod 332 is located at the top of the pressure-bearing block 331. There are two guide rods 332, and the two guide rods 332 are located at both ends of the pressure-bearing block 331, and the bottom of the guide rod 332 is fixedly connected to the top of the pressure-bearing block 331. Two guide holes corresponding to the two guide rods 332 are formed in the pressure block 333, and the guide rod 332 is slidably matched with the guide hole. After the strip steel is positioned and corrected by the transverse positioning portion 32, the strip steel is clamped by the pressure block 333 and the pressure-bearing block 331, further reducing the possibility of the strip steel moving during welding.

[0044] The implementation principle of the strip steel welding positioning device in the embodiment of the present application is as follows: when it is necessary to align the tail of the previous strip steel with the head of the next strip steel, the staff makes the adjusting plate 3233 drive the sliding rod 3231 to move through the pull ring 3236, and drives the transverse sliding block 322 to move away from the transverse fixing block 321 inside the positioning hole 311 through the sliding rod 3231. Then, the tail of the previous strip steel is inserted into the positioning hole 311. Again, the transverse positioning portion 32 is used to make the transverse sliding block 322 move towards the transverse fixing block 321, and the side of the previous strip steel in the length direction is inserted into the adjacent positioning groove 3211. The previous strip steel is positioned and corrected by the inner wall of the positioning groove 3211 on the transverse fixing block 321 and the transverse sliding block 322, so as to improve the morphological stability of the tail of the previous strip steel during welding. Then, the pressure block 333 is placed on the pressure-bearing block 331 through the guide rod 332, and the tail of the previous strip steel is pressed tightly on the pressure-bearing block 331 by the pressure block 333. The next strip steel is placed in the positioning hole 311 inside the corresponding positioning seat 31 in the same way. Then, the staff makes the two positioning seats 31 drive the previous strip steel and the next strip steel to approach each other on the docking platform 2. After the tail of the previous strip steel is aligned with the head of the next strip steel, the limiting rod 3121 is rotated so that the bottom of the limiting rod 3121 abuts against the docking platform 2, so as to reduce the stability of welding the heads of the previous strip steel and the next strip steel and the efficiency of aligning the two strip steels.

[0045] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
