[0034] The fixed fixture 11 is slidably connected to a movable fixture 12 inside, and the movable fixture 12 includes a rotating shaft 122, a rectangular block is fixedly connected to one side of the rotating shaft 122, a circular stopper is fixedly connected to one side of the rectangular block, a spring is fixedly connected to the other side of the circular stopper, the surface of the rotating shaft 122 is rotatably connected to the circular through hole of the rotating base 115, and a vertical slide 121 is fixedly connected to the other side of the rotating shaft 122, one side of the vertical slide 121 is in a reverse L shape, one side of the vertical slide 121 is fixedly connected to a rectangular groove, one side of the vertical slide 121 is fixedly connected to a top beam 123, and the front side of the top beam 123 is fixedly connected There is a rectangular rubber pad, a fixture slide box 124 is fixedly connected to the front of the vertical slide 121, the number of the vertical slide 121, the rotating shaft 122, and the fixture slide box 124 are all three and are symmetrically distributed on both sides of the top beam 123, the surface of the other side of the fixture slide box 124 is serrated, one side of the fixture slide box 124 is fixedly connected to a rectangular blind hole, the front of the fixture slide box 124 is fixedly connected to a rectangular blind hole, the rectangular blind hole on the front of the fixture slide box 124 is connected to the rectangular blind hole on one side, the inside of the fixture slide box 124 is fixedly connected to a light rod 126, and the inside of the fixture slide box 124 is rotatably connected to a sliding screw rod 125, The back of the sliding screw rod 125 is fixedly connected with a handle, and the interior of the light rod 126 is slidably connected with a clamping slide 127. The top cross-section of the clamping slide 127 is U-shaped. The back of the clamping slide 127 is slidably connected to the sliding screw rod 125, and the back of the clamping slide 127 is slidably connected to the light rod 126. The back of the clamping slide 127 is fixedly connected with a clamping pressure block 128, and the back of the clamping pressure block 128 is fixedly connected with a rubber pad. The other side of the clamping slide 127 is connected with two circular through holes. The interior of the clamping slide 127 is slidably connected to the clamping tooth plate 129 through the circular through holes. The surface of the other side of the clamping tooth plate 129 It is a sawtooth shape, and the clamping tooth plate 129 is slidably connected to the two circular through holes of the clamping slide 127 through two threaded rods. Four hexagonal nuts are threaded on the surface of the threaded rods, two of which are located on the other side of the clamping slide 127, and the other two are located on one side of the clamping tooth plate 129. There are two clamping slides 127, clamping pressure blocks 128, and clamping tooth plates 129. After the clamp clamps the plate, it is fixed with screws and nuts to fit the tooth plates, which increases the fixed contact area of ​​the clamp, increases the force-bearing area of ​​the fixed surface of the clamp, and thereby improves the stability of the clamp's clamping of the plate for a long time.

[0035] When in use, after the plate to be welded is prepared, the plate to be welded at the bottom is placed on the top of the bottom base 111. After it is placed securely, the hexagonal nut is rotated downward with a hexagonal wrench. The hexagonal nut presses the bottom pressure plate 113 downward along the vertical direction of the fixing screw 112 through the gasket. At the same time, the bottom of the bottom pressure plate 113 squeezes the spring, and the bottom of the plate is squeezed against the top of the bottom base 111. When the rubber pad at the bottom of the bottom pressure plate 113 is completely in contact with the plate and the hexagonal nut cannot be rotated downward any further, stop rotating the hexagonal nut downward to complete the fixation of the bottom plate.

[0036] After the plate at the bottom is fixed, the plate to be fixed on the movable clamp 12 is lifted, and the plate is passed through the area between the top beam 123 and the clamping block 128. After determining the position of the plate, the handle of the sliding screw rod 125 behind the top beam 123 is shaken, and the sliding screw rod 125 rotates to drive the clamping slide 127 to move, and the clamping slide 127 drives the clamping block 128 to move until the rubber pad of the clamping block 128 is squeezed with the plate, and the back of the plate is squeezed with the rubber pad of the top beam 123. When the sliding screw rod 125 cannot be shaken because the clamping slide 127 cannot continue to move, the hexagonal nut on the threaded rod of the clamping tooth plate 129 is loosened, and the position of the clamping tooth plate 129 is adjusted until the tooth plate on the clamping tooth plate 129 is fully engaged with the tooth plate of the clamping slide 127, and the hexagonal nut is tightened, which makes the clamping tooth plate 129 unable to slide, thereby fixing the clamp position of the movable clamp 12.

[0037] Example 2: Please refer to Figure 1-9 , based on the first embodiment, the present invention provides a technical solution: an electromagnetic clamp 2 is fixedly connected to one side of the fixed clamp 11, the number of the electromagnetic clamps 2 is two, the other side of the electromagnetic clamp body 21 is fixedly connected to one side of the fixed clamp 11, the electromagnetic clamp body 21 is rotatably connected to the movable clamp 12, the front cross-section of the electromagnetic clamp body 21 is an inverted J-shape, the other side of the inner wall of the electromagnetic clamp body 21 is connected with a circular through hole, the other side of the inner wall of the electromagnetic clamp body 21 is fixedly connected with two circular blind holes, the surface of the circular blind hole is fixedly connected with an electromagnetic coil, one side of the electromagnetic clamp body 21 is connected with a circular blind hole, the electromagnetic clamp body 21 is rotatably connected to the surface of the rotating shaft 122 through the circular through hole on the other side, one side of the inner wall of the electromagnetic clamp body 21 is fixedly connected with a circle of cylindrical blocks, the number of rubber cylindrical block groups is thirty and they are symmetrically distributed about the axis of the rotating shaft 122;

[0038] The front cross-section of the electromagnetic clamp body 21 is an inverted J-shape, and a circular through hole is connected to the other side of the inner wall of the electromagnetic clamp body 21, and two circular blind holes are fixedly connected to the other side of the inner wall of the electromagnetic clamp body 21, and an electromagnetic coil is fixedly connected to the surface of the circular blind hole, and a circular blind hole is connected to one side of the electromagnetic clamp body 21, and the electromagnetic clamp body 21 is rotatably connected to the surface of the rotating shaft 122 through the circular through hole on the other side, and a circle of cylindrical blocks is fixedly connected to one side of the inner wall of the electromagnetic clamp body 21, and the number of rubber cylindrical block groups is thirty and is symmetrically distributed about the axis of the rotating shaft 122;

[0039] Preferably, the inside of the electromagnetic clamp body 21 is slidably connected to a clamp pressure plate 22 through a circular blind hole, and two metal round rods are fixedly connected to the other side of the clamp pressure plate 22, and the metal round rods are slidably connected to the circular blind holes on the other side of the clamp pressure plate 22, and the rectangular hole surface of the rotating shaft 122 is slidably connected to a follower disk 23, and a circle of circular blind holes is fixedly connected to the surface of one side of the follower disk 23, and the number, diameter and position of the circular blind holes on one side of the follower disk 23 correspond to the cylindrical block on one side of the inner wall of the electromagnetic clamp body 21. The friction force when the electromagnetic clamp 2 clamps the follower disk 23 limits the rotation of the movable clamp 12, thereby achieving the fixation of the welding angle of the distribution cabinet box, and at the same time, the connection between the cylindrical block on the clamp body and the circular blind hole of the follower disk 23 further improves the stability of the clamp during clamping, and reduces the probability of shaking of the movable clamp due to fatigue loosening.

[0040] When in use, after completing the fixing process of the two plates in Example 1, rotate the position of the movable clamp 12, adjust the movable clamp 12 to the angle required for welding and docking, start the driver 24, and after the driver 24 is started, control the electromagnetic clamp 2 to start. After the electromagnetic clamp 2 is started, the electromagnetic coil inside the electromagnetic clamp body 21 is energized to generate electromagnetic force, and the electromagnetic force drives the metal round rod of the clamp pressure plate 22 to slide in the direction of the follower disk 23, thereby driving the clamp pressure plate 22 to slide in the direction of the follower disk 23. After the clamp pressure plate 22 contacts the follower disk 23, the clamp pressure plate 22 drives the follower disk 23 to slide along the rectangular block of the rotating shaft 122. At this time, The surface of the moving disk 23 is squeezed against the spring of the rotating shaft 122 until the circular blind hole of the moving disk 23 is plugged into the cylindrical block of the electromagnetic clamp body 21. The electromagnetic clamp body 21 is continuously energized to maintain the squeezing state of the clamp pressure plate 22 on the moving disk 23 and the plugging state of the cylindrical block of the electromagnetic clamp body 21 and the circular blind hole of the moving disk 23, thereby achieving the fixation of the movable clamp 12. At this time, the moving disk 23 cannot rotate due to the friction between the clamp pressure plate 22 and the plugging with the electromagnetic clamp body 21, and the movable clamp 12 slidingly connected to the moving disk 23 cannot rotate either, thereby achieving the fixation of the movable clamp 12, and then welding work can be carried out.

[0041] Example 3: Please refer to Figure 1-12On the basis of the first and second embodiments, the present invention provides a technical solution: a loose feedback bracket 3 is slidably connected to the top of the fixed fixture 11, the number of the loose feedback brackets 3 is two, the other side of the loose feedback bracket 3 is slidably connected to one side of the movable fixture 12, the loose feedback bracket 3 includes a bracket slider 31, the top of the bracket slider 31 is connected with a circular through hole, the top of the bracket slider 31 is fixedly connected to a sliding cylinder 32, one side surface of the sliding cylinder 32 is fixedly connected to a driver 24, the interior of the sliding cylinder 32 is a hollow structure, the bottom of the inner wall of the sliding cylinder 32 is fixedly connected to a spring, the bottom of the sliding cylinder 32 is fixedly connected to a distance sensor 33, the bottom of the distance sensor 33 is electrically connected to the driver 24 through a wire, the interior of the sliding cylinder 32 is slidably connected to a feedback slide bar 34, and the feedback slide bar The bottom of 34 is fixedly connected to the top of the spring inside the sliding cylinder 32, and the top of the feedback slide rod 34 is fixedly connected to a feedback joint 35 through a cylindrical rod. The other side of the feedback joint 35 is rotatably connected to a roller, and the surface of the roller is slidably connected to the rectangular groove on one side of the vertical slide 121. The loose feedback bracket 3 applies a reaction force through the spring inside it. When the loosening amplitude of the movable clamp 12 is small, the downward movement of the movable clamp 12 can be delayed. At the same time, the slide rod distance change signal is fed back by the distance sensor 33 inside the bracket. When the distance gradually decreases, the driver 24 increases the output current, thereby increasing the pressure applied by the clamp pressure plate 22 of the electromagnetic clamp 2 on the follower plate 23, thereby achieving precise control of the adverse phenomenon of the movable clamp 12 shaking and moving downward, and improving the stability and reliability of the tooling clamping.

[0042] When in use, after executing the process of Example 1, in the process of Example 2, the bracket slide block 31 is slid along the rectangular groove at the top of the positioning slideway 114 to adjust the position of the bracket slide block 31, and the vertical relationship between the loose feedback bracket 3 and the positioning slideway 114 is maintained. After determining the position of the bracket slide block 31, the cylindrical pin is passed through the circular through hole at the top of the bracket slide block 31 and the circular blind hole at the bottom of the rectangular groove of the positioning slideway 114 to fix the position of the bracket slide block 31. When the movable clamp 12 begins to loosen due to the unstable clamping of the clamp pressure plate 22 and the follower plate 23, the movable clamp 12 will rotate downward under the action of gravity, thereby causing the vertical slide 121 and the pulley of the feedback joint 35 to slide relative to each other. At the same time, because the position of the bracket slide block 31 has been fixed, the feedback joint 35 is squeezed by the vertical slide 121. It starts to move downward, the feedback connector 35 drives the feedback slide bar 34 to slide downward, the feedback slide bar 34 squeezes the spring to delay the downward sliding process of the movable clamp 12, and the distance between the feedback slide bar 34 and the distance sensor 33 gradually decreases. The distance sensor 33 feeds back a signal of the distance change between the distance sensor 33 and the feedback slide bar 34 to the driver 24. After receiving the signal of the distance reduction, the driver 24 increases the current leading to the electromagnetic clamp body 21, thereby increasing the electromagnetic force of the electromagnetic clamp body 21, and increasing the pressure of the clamp pressure plate 22 on the follower disk 23, resulting in an increase in the friction between the clamp pressure plate 22 and the follower disk 23, until the movable clamp 12 stops moving downward, the signal fed back by the distance sensor 33 is analyzed by the driver 24 and judged to be unchanged in distance, and the driver 24 maintains the current leading to the electromagnetic clamp body 21;

[0043] When the welding cooling work is completed, loosen the hexagonal nut, and then loosen the clamping tooth plate 129 and the bottom pressure plate 113, lift the welded product out of the tooling, then pull out the cylindrical pin inside the bracket slider 31, turn off the driver 24, and cut off the power to the electromagnetic clamp body 21. The follower disk 23 drives the clamp pressure plate 22 to reset under the action of the spring, and the movable clamp 12 resumes free rotation.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
