Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a high-efficiency transformer core flipping device. Background Art

[0002] The iron core is the core part of the transformer used to conduct and concentrate the magnetic field. A well-designed iron core structure can reduce these losses. By stacking thin iron cores, the length of the magnetic flux path can be increased, thereby increasing the magnetic permeability of the transformer and reducing iron losses, thereby improving energy transmission efficiency. After stacking, the iron core needs to be flipped to facilitate subsequent processing steps such as coil installation.

[0003] A Chinese patent discloses a transformer core flipping device (authorization announcement number CN216562747U), which includes a supporting base plate, an L-shaped flipping platform is arranged above the supporting base plate, a transformer core is placed on the top of the L-shaped flipping platform, two support rods arranged symmetrically in front and back are fixed on the top of the supporting base plate, the support rods are arranged vertically upward, a flip shaft is fixed between the tops of the two support rods, two hinge seats arranged symmetrically in front and back are fixed on the outer side of the lower part of the vertical section of the L-shaped flipping platform, the hinge seats are sleeved outside the flip shaft and are rotatably connected to the flip shaft, a flipping cylinder is arranged between the bottom of the horizontal section of the L-shaped flipping platform and the top of the supporting base plate, and the two ends of the flipping cylinder are respectively hinged to the L-shaped flipping platform and the supporting base plate; a clamping mechanism for clamping the top of the transformer core is arranged on the inner side of the upper part of the vertical section of the L-shaped flipping platform. The flipping efficiency is high, manpower is saved, and the transformer core can be clamped and fixed during the flipping process to prevent the transformer core from tipping over during flipping, which is convenient to use.

[0004] This patented technology has the advantage of preventing tipping when in use, but it still has shortcomings when in use. Since the core stacking process is manual stacking, the stacked cores have problems of offset and looseness, which affects subsequent processing and causes uneven distribution of the transformer magnetic field, increases eddy current loss and hysteresis loss, and affects the transmission characteristics and efficiency of the transformer. Therefore, those skilled in the art provide a high-efficiency transformer core flipping device to solve the problems raised in the above background technology. Utility Model Content

[0042] Example 1

[0043] See also Figure 1-Figure 5 As shown, this embodiment is a high-efficiency transformer core flipping device, including a mounting base 100,

[0044] The clamping structure 200 includes a mounting frame 216, a clamping plate 1 201 located inside the front and rear sides of the mounting frame 216, a clamping plate 209 located at the front and rear ends of the mounting frame 216, a screw hole 205 opened inside the clamping plate 1 201, a motor 1 203 located at the front end of the mounting frame 216, a screw rod 1 206 located at the output end of the motor 1 203 and rotatably plugged into the screw hole 205, a motor 204 located at the rear end of the mounting frame 216, a nut 212 located at one end of the clamping plate 209, a screw rod 213 located at the output end of the motor 204 and rotatably plugged into the nut 212, and an extension plate 202 located at the lower end of the clamping plate 1 201;

[0045] The second clamping plate 209 has a travel groove 210 formed inside, and the first clamping plate 201 is located inside the travel groove 210;

[0046] Both ends of the mounting frame 216 are provided with travel openings 207, and both ends of the clamping plate 1 201 pass through the travel openings 207;

[0047] A slider 211 is disposed at the lower end of the clamping plate 201, and a slide groove 208 is provided on the inner wall of the lower end of the travel opening 207, and the slider 211 is slidably installed inside the slide groove 208;

The threads on the outer walls of the screw rod 1 206 and the screw rod 213 are relatively distributed.

[0049] Using the clamping structure 200;

[0050] The transformer cores are placed inside the placement frame for stacking. After stacking, the motor 204 drives the screw 213 to rotate, and the clamping plate 209 is guided by the sliding sleeve 215. The screw 213 pushes the nut 212 to drive the clamping plate 209 to move relatively, clamping the front and rear ends of the stacked transformer cores. The motor 203 drives the screw 206 to rotate. When the clamping plate 201 moves horizontally inside the installation frame 216 through the slider 211, it is guided by the sliding guide. The screw 206 pushes the screw hole 205, so that the clamping plate 201 clamps the two ends of the stacked cores, and the extension plate 202 contacts the lower end of the stacked cores. The four sides of the stacked cores are clamped. In this process, the misplaced and misaligned cores are regularized, and the stacked cores avoid manual secondary alignment, thereby realizing efficient correction of the stacked cores. While ensuring the stability of the stacked cores, effective, automatic and efficient correction processing is obtained before subsequent processing before flipping.
