Description

Technical Field

[0001] The invention relates to the field of transformer shells, in particular to a transformer shell butt joint auxiliary clamp. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. During the production process of the transformer, the outer shell and the base need to be fixedly connected to form the overall shape of the transformer. During this process, a clamp is needed to fix the outer shell and the base respectively.

[0003] When the existing transformer shell docking clamp is used, it is necessary to clamp the U-shaped shell in the middle of the transformer. Therefore, when clamping the opening position of the U-shaped shell, some clamps do not have parts to support the open end of the U-shaped shell, which makes the open end of the U-shaped shell collapse inward during clamping and cannot be calibrated with other parts, and some clamps with supports can only support fixed specifications, making it inconvenient to use. Therefore, it is necessary to propose a transformer shell docking auxiliary clamp. Summary of the invention

[0025] A threaded sleeve 11 is rotatably connected to the groove wall of the fixed groove 2 through a bearing, a threaded rod 12 is internally threadedly connected to the threaded sleeve 11, one end of the threaded rod 12 extends into the fixed groove 2 and is fixedly connected to a support plate 13, one end of the threaded sleeve 11 extends outside the box body 1 and is fixedly sleeved with a driven gear 14, a rotating rod 15 is rotatably connected to the outer wall of the box body 1 through a bearing, a driving gear 16 is fixedly sleeved on the rod wall of the rotating rod 15, the driving gear 16 is meshed and connected with the driven gear 14, and a rotating handle 17 is fixedly installed on the rotating rod 15;

[0026] A box body 18 is fixedly installed on the slot of the fixing slot 2, an installation cavity 19 is opened inside the box body 18, a receiving groove 20 is opened on the outer wall of the box body 18, a first airbag 21 is fixedly installed inside the cavity wall of the installation cavity 19, a second airbag 22 is fixedly installed inside the receiving groove 20, a connecting tube 23 is fixedly installed between the installation cavity 19 and the receiving groove 20, a sliding hole 24 is opened through the cavity wall of the installation cavity 19, a push rod 25 is slidably connected in the sliding hole 24, one end of the push rod 25 extends into the installation cavity 19 and is fixedly connected to a push plate 26, and the push plate 26 is fixedly connected to the first airbag 21.

[0027] Among them, the first clamping blocks 9 and the second clamping blocks 10 are both arranged in four pieces, and the first clamping blocks 9 are arranged opposite to each other in pairs, and the second clamping blocks 10 are arranged opposite to each other in pairs. The bottom plate 27 is clamped by the first clamping blocks 9, and the top plate 28 is clamped by the second clamping blocks 10.

[0028] The mounting block 7 is slidably connected in the mounting groove 4, and the moving block 8 is slidably connected in the moving groove 3, so that the mounting block 7, the moving block 8 and the first clamping block 9 can only move in parallel.

[0029] Among them, the threaded sleeve 11 and the threaded rod 12 are both set in two, the two threaded sleeves 11 are set in parallel, and the two threaded rods 12 are set in parallel.

[0030] Among them, the two ends of the connecting tube 23 are respectively connected to the first airbag 21 and the second airbag 22. When the first airbag 21 is squeezed, the air inside it will be injected into the second airbag 22 through the connecting tube 23, and the second airbag 22 will expand outward. When the first airbag 21 stops squeezing, the first airbag 21 and the second airbag 22 will recover under their own elasticity, and the air inside the second airbag 22 will return to the first airbag 21 through the connecting tube 23.

[0031] When in use, first insert the bottom plate 27 between the first clamping blocks 9, then insert the top plate 28 between the second clamping blocks 10, and then drive the rotating rod 15 to rotate by turning the handle 17, and the rotating rod 15 will drive the driving gear 16 to rotate, and the driving gear 16 drives the threaded sleeve 11 to rotate by meshing with the driven gear 14, and the threaded sleeve 11 drives the support plate 13 to move in the fixed groove 2 by cooperating with the threaded rod 12, and the support plate 13 will abut against the top plate 28 and the bottom plate 27, and push the top plate 28 and the bottom plate 27 until they abut against the groove wall of the fixed groove 2. At this time, the fixed groove 2, the support plate 13, and the top plate 2 8 and the bottom plate 27 together form a processing space corresponding to the size of the transformer shell. At this time, the U-shaped plate 29 is inserted into the processing space in an inverted U shape, and then the driving cylinder 5 can be started. The driving cylinder 5 will pull the mounting block 7 through the piston rod 6, and the mounting block 7 will drive the moving block 8 and the first clamping block 9 to move in parallel, and the first clamping block 9 will drive the bottom plate 27 to move, and the bottom plate 27 will first abut against the U-shaped plate 29, and push the other end of the U-shaped plate 29 to abut against the top plate 28, and during the movement of the first clamping block 9, it will abut against the push rod 25 and push the push rod 25, and the push rod 25 will squeeze the first airbag 21 through the push plate 26, and the first airbag 21 will be pressed against the top plate 28. The air in the first airbag 21 is injected into the second airbag 22 through the connecting tube 23, and the second airbag 22 expands outward and pushes the side plates of the U-shaped plate 29 outward by abutting against the inner wall of the U-shaped plate 29, so that the side plates of the U-shaped plate 29 are fully opened and respectively abut against the groove wall of the fixing groove 2 and the support plate 13, and the openings at both ends of the U-shaped plate 29 completely overlap with the bottom plate 27 and the top plate 28, so as to avoid the inward collapse of the U-shaped plate 29 and the inability to calibrate the connection, thereby facilitating the calibration and docking of the interfaces of transformer shells of different sizes; after the processing of the transformer shell is completed, it is taken out, and then the support plate 13 is driven to move by turning the handle 17 To the edge of the fixed groove 2, and then start the driving cylinder 5, and the driving cylinder 5 drives the mounting block 7, the moving block 8 and the first clamping block 9 to reset through the piston rod 6, and the first clamping block 9 releases the squeezing of the push rod 25 and the push plate 26.
