The sliding rod 2015 is slidably installed on the vertical pole 209, and the fixed rod 2019 is arranged below the sliding rod 2015, and the fixed rod 2019 is fixedly installed on the side of the vertical pole 209. The sliding plate 2016 and the limit plate 2013 are symmetrically arranged at both ends of the sliding rod 2015, and the sliding plate 2016 and the limit plate 2013 are fixedly connected to the sliding rod 2015. The sliding plate 2016 is slidably installed on the fixed rod 2019. The third spring 2018 is sleeved on the fixed rod 2019, and the third spring 2018 is located between the sliding plate 2016 and the vertical rod 209. The side wall of the limit plate 2013 cooperates with the side wall of the push plate 2025.

[0074] The setting of the limit piece 208 can serve the purpose of limiting the core clamp, ensuring the safety and stability of the core clamp during the assembly and welding process, and improving the quality of assembly and welding of the welded core clamp. The setting of the limit plate 2013 can limit the side wall of the core clamp. The setting of the sliding rod 2015, the third spring 2018 and the fixed rod 2019 can ensure that the limit plate 2013 moves with the push plate 2025, thereby achieving the purpose of fixing the core clamp.

[0075] As an optimization solution of the present invention, Fig.11As shown, a limiting mechanism is also provided on the limiting plate 2013, and the limiting mechanism includes a second threaded rod 2021, a handle 2020 and a side plate 2022. The second threaded rod 2021 is threadedly connected to the limiting plate 2013, the handle 2020 and the side plate 2022 are symmetrically arranged at both ends of the second threaded rod 2021, the handle 2020 is fixedly connected to one end of the second threaded rod 2021, and the side plate 2022 is rotatably connected to the other end of the second threaded rod 2021, and a groove 2014 is opened on the limiting plate 2013, and the groove 2014 cooperates with the side plate 2022.

[0076] The setting of the limiting mechanism cooperates with the function of the blocking bar 6 to fix the core clamp on the placement plate 5, ensuring the stability of the core clamp during assembly or welding. By rotating the handle 2020, the second threaded rod 2021 is driven to rotate, and the second threaded rod 2021 rotates to drive the side plate 2022 to move toward one side of the core clamp, thereby achieving the purpose of fixing core clamps of different sizes.

[0077] Example 1

[0078] During operation, the core clamp is placed on the placement plate 5, and the motor 201 is turned on to drive the rotating rod 206 to rotate. The rotation of the rotating rod 206 drives one end of the push-pull rod 203 to move. The movement of one end of the push-pull rod 203 will pull the sliding frame 204 toward the middle of the placement plate 5, thereby achieving the purpose of positioning the core clamp. After the positioning is completed, the cylinder 701 contracts the piston rod to drive the lifting plate 708 to move downward. The downward movement of the lifting plate 708 will drive the rotating arm 703 to move around the rotating axis 7024 to the center line position away from the mounting plate 702. While the rotating arm 703 rotates, the sliding block 709 will move along the guide rod 7011. While the sliding block 709 moves, the first spring 7010 is compressed until the lower pressure plate 704 contacts the top of the core clamp, thereby achieving the purpose of fixing the core clamp on the placement plate 5, and then the core clamp is welded.

[0079] Example 2

[0080] The adjusting mechanism 705 provided on the rotating arm 703, when one side of the lower pressing plate 704 contacts the core clamp, the lower pressing plate 704 will rotate, and the lower pressing plate 704 will drive the driving wheel 7017 to rotate, and the driving wheel 7017 will mesh with the rack 7022, and the rotation of the driving wheel 7017 will drive the rack 7022 to move, and the movement of the rack 7022 will drive the connecting plate 7020 to move along the guide rod 7019, and the movement of the connecting plate 7020 along the guide rod 7019 will compress the second spring 7017. 018. The setting of the second spring 7018 is convenient for driving the rack 7022 to reset. The reset of the rack 7022 drives the driving wheel 7017 to rotate. The rotation of the driving wheel 7017 drives the rotating shaft 7016 to rotate. The rotation of the rotating shaft 7016 drives the lower pressure plate 704 to rotate, thereby ensuring that the lower pressure plate 704 is always in a tilted state to prevent the lower pressure plate 704 from causing unnecessary damage to the core clamp at the corners of the lower pressure plate 704 and the connection with the core clamp when the lower pressure plate 704 moves downward, thereby greatly ensuring the clamping quality of the core clamp by the device.

[0081] Example 3

[0082] In order to ensure that the device can position core clamps of different sizes, a positioning mechanism 207 is also installed on the positioning plate 205. Turning the knob 2023 drives the first threaded rod 2024 to rotate, and the rotation of the first threaded rod 2024 drives the pushing plate 2025 to move. The movement of the pushing plate 2025 can achieve the purpose of positioning and fixing the core clamp, thereby ensuring the safety and stability of the core clamp during assembly or welding. In the process of moving the pushing plate 2025, the limit plate 2013 will be driven to move, and the movement of the limit plate 2013 will also drive the limit mechanism to move, thereby ensuring that the limit mechanism can always limit the side wall of the core clamp, thereby ensuring the safety and stability of the limit mechanism during operation.

[0083] Example 4

[0084] When there is a deviation between the middle of the iron core clamp to be positioned and the middle of the placement plate 5, first screw the positioning mechanism 207 on one end of the positioning plate 205, turn the knob 2023 to drive the first threaded rod 2024 to rotate, and the first threaded rod 2024 rotates to drive the push plate 2025 to move, thereby pushing the push plate 2025 out, and then turn on the motor 201 to drive the rotating rod 206 to rotate, and the rotating rod 206 rotates to drive one end of the push-pull rod 203 to move, and the movement of one end of the push-pull rod 203 will pull the sliding frame 204 toward the middle of the placement plate 5, thereby achieving the purpose of positioning the iron core clamp. Since the push plate 2025 in the positioning mechanism 207 on one of the positioning plates 205 is pushed out, when the iron core clamp is positioned, there is a deviation between the iron core clamp and the middle of the placement plate 5, thereby achieving the purpose of fixing the iron core clamp.

[0085] Example 5

[0086] When it is necessary to clamp iron core clamps of different sizes, when it is necessary to clamp iron core clamps of smaller size, the iron core clamps are placed on the placement plate 5, and the lifting mechanism 4 can also be opened to drive the placement plate 5 to rise. After the placement plate 5 rises, the rotating arm 703 only needs to rotate a smaller angle (that is, the distance that the lower pressure plate 704 descends is reduced, and the distance between the lower pressure plates 704 on the rotating arms 703 on both sides of the center line of the mounting plate 702 is also reduced), so that the smaller iron core clamps can be fixed. Conversely, when it is necessary to clamp larger size, the iron core clamps are placed on the placement plate 5, and the lifting mechanism 4 can also be opened to drive the placement plate 5 to descend. After the placement plate 5 descends, the rotating arm 703 only needs to rotate a larger angle (that is, the distance that the lower pressure plate 704 descends is increased, and the distance between the lower pressure plates 704 on the rotating arms 703 on both sides of the center line of the mounting plate 702 is also increased), so that the larger lifting clamps can be fixed.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the scope defined by the structure of the present invention, they shall all fall within the protection scope of the present invention.
