Description

Technical Field

[0001] The invention relates to the technical field of transformer coil pressing, in particular to transformer coil pressing equipment. 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). The main functions of a transformer are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields.

[0003] As an indispensable part of the transformer, during the assembly of the transformer, the coil is first placed on the workbench of the pressing equipment, and the position is reasonably adjusted according to the structure of the coil. Then the pressing equipment is started to press the coil. The pressing process is controlled according to the pressure and temperature displayed by the equipment to ensure uniform pressure and appropriate temperature. After the coil is pressed, quality inspection is carried out immediately.

[0004] The patent document with announcement number CN116631767B discloses a device for integrally encapsulating transformer coils. When the clamping assembly extends to the upper position of the inner side of the coil body, the hollow hydraulic cylinder drives the piston rod to move downward, and the clamping assembly is pushed to expand outward, so that the surface of the clamping assembly is in close contact with the inner side of the coil body. The anti-damage mechanism drives the coil body to the upper position of the transformer shell for encapsulation, which solves the problem of using a hook to lift the coil encapsulation, which may cause the iron core to scratch the coil cardboard due to coil deflection.

[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems: The transformer coil overall package equipment uses the anti-damage mechanism to open the clamping component from the inside of the coil to the outside to clamp and fix the coil, which can prevent the coil from being damaged when the relevant components are pressed onto the coil. However, in actual application, this method is not easy to quickly complete the stamping work of the coil during press-fitting because there are supports blocking the inside of the coil. Summary of the invention

The embodiment of the present application provides a transformer coil press-fitting device, which clamps and fixes the transformer coil by three clamping rods and uses two clamping arms to hold the transformer housing to achieve the fixing effect. The vertical screw rod assembly can control the support plate seat to move to the bottom, so that the support plate seat drives the pressing plate to pass between two adjacent clamping rods, and the transformer coil is pressed into the interior of the transformer housing. Since there is no obstruction on the inside of the transformer coil, it is convenient to quickly complete the press-fitting of the transformer coil and the transformer housing, thereby achieving the effect of improving the press-fitting efficiency.

[0020] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0021] Embodiment 1:

[0022] This embodiment introduces a specific structure of a transformer coil press-fitting device. Figure 1-Figure 5 As shown, it includes a vertical screw assembly 1 and a horizontal screw assembly 5 arranged at the bottom of the vertical screw assembly 1 (the horizontal screw assembly 5 and the vertical screw assembly 1 use conventional means in the screw drive technology, which will not be repeated here), a bearing table 7 is arranged on the top of the horizontal screw assembly 5, and a second clamping structure 6 is assembled and connected to the top of the bearing table 7, a press-fit structure 2 is arranged on the surface of the vertical screw assembly 1, and a first clamping structure 3 is arranged between the second clamping structure 6 and the press-fit structure 2; The bottom of the horizontal screw assembly 5 is assembled and connected with the equipment base frame 4, the top of one side of the equipment base frame 4 is assembled and connected with the gantry frame 9, both ends of the gantry frame 9 are assembled and connected with the side frame 10, and two cross bars 11 are assembled and connected between the two side frames 10, the vertical screw assembly 1 is assembled to the outside of the two cross bars 11, and the first clamping structure 3 is assembled between the two side frames 10 away from the bottom of the gantry frame 9; like Figures 3 to 5 As shown, the first clamping structure 3 includes two plates 302, one end of the two plates 302 is assembled with a connecting plate frame 303, the top of the center of the connecting plate frame 303 and the top of one end of the two plates 302 are both provided with a first clamping support 304, and one side of the three first clamping supports 304 is provided with a clamping rod 301; By assembling and fixing the other ends of the two plates 302 to the surfaces of the two side plate frames 10 away from the bottom of the gantry frame (9), the three first clamping supports 304 and the three clamping rods 301 are arranged in a regular triangle, and the transformer coil can be installed between the three clamping rods 301 from top to bottom, and the transformer coil is positioned by the three clamping rods 301; At the same time, the three clamping rods 301 are all made of a vertically oriented vertical rod and an inclined rod in one piece. When the transformer coil is installed between the three clamping rods 301 and positioned, it can be guided by the inclined rod first and then positioned by the vertical rod to ensure that the axis of the transformer coil is vertically downward. Secondly, in order to enable the three clamping rods 301 to clamp and fix transformer coils of different diameters, such as Figure 4As shown, a second spring 307 is arranged between the clamping rod 301 and the first clamping support 304, a third threaded rod 305 is processed in the middle of the clamping rod 301 near the first clamping support 304, and a second guide rod 306 is processed at the top and bottom of the clamping rod 301 near the first clamping support 304. The second guide rod 306 is slidably connected to the inside of the first clamping support 304, one end of the third threaded rod 305 passes through the inside of the first clamping support 304, and is threadedly connected to the third nut 308, so that the second spring 307 is supported between the first clamping support 304 and the clamping rod 301. When the transformer coil is installed between the three clamping rods 301, the clamping rod 301 can compress the second spring 307, so as to adapt to a variety of transformer coils within a certain diameter range; In some examples, a third guide rod 311 is processed on one side of the bottom of the first clamping support 304, and a fourth threaded rod 310 is processed on the other side of the bottom of the first clamping support 304; Among them, by making the third guide rod 311 and the fourth threaded rod 310 pass through the connecting plate frame 303, or pass through the inside of the plate 302, and threading the fourth nut 309 at one end of the fourth threaded rod 310, the first clamping support 304 can be fixed on the top of the connecting plate frame 303, or fixed on the top of the first clamping support 304.

[0023] Embodiment 2:

[0024] Based on Example 1, Figures 1 to 3 , Figures 6 to 8 As shown, this embodiment introduces the specific structure of the second clamping structure 6 and the press-fitting structure 2. The second clamping structure 6 includes two mutually symmetrical support blocks 601. The interiors of the two support blocks 601 are both slidably connected with driving rods 603. The interiors of one corner of the two support blocks 601 are both hingedly connected with clamping arms 602. The interiors of one end of the clamping arms 602 are pin-connected with a pin rod 604. The interiors of one end of the driving rod 603 are provided with a first strip groove 8. The top of the press-fit structure 2 is controlled by the vertical screw assembly 1 to move from the top to the bottom. When the press-fit plate 201 on the press-fit structure 2 passes through the three clamping rods 301, the transformer coil fixed to the inside of the first clamping structure 3 can be pushed to move toward the bottom. When the transformer coil moves to the top of the transformer housing, it can enter the inside of the transformer housing. like Figure 6 and Figure 7 As shown, the press-fit structure 2 includes a support plate seat 202, a fixing seat 203 is arranged on the top of the support plate seat 202, a press-fit plate 201 is formed integrally on one side surface of the fixing seat 203, a sliding back plate 208 is arranged on one side of the bottom of the support plate seat 202, and a leaning seat block 207 is arranged on one side of the bottom of the sliding back plate 208; The support block 207 is located at the bottom of the support plate seat 202, and one end of the two driving rods 603 are processed with inclined surfaces. The cross-section of the support block 207 is an isosceles trapezoid. The two clamping arms 602 are symmetrically arranged, and the pin rod 604 passes through the inside of the first strip groove 8. When the horizontal screw assembly 5 drives the bearing table 7 to drive the second clamping structure 6, so that the transformer housing located on the inner side of the second clamping structure 6 moves to the bottom of the first clamping structure 3, the two driving rods 603 on one side of the second clamping structure 6 contact with the bottom of the press-fitting structure 2. With the support of the support block 207, the inclined surface on the support block 207 can be matched with the inclined surface of one end of the driving rod 603, so that the driving rod 603 slides inside the support block 601 (the two driving rods 603 move away from each other), and the clamping arm 602 is controlled to rotate around the hinge point between it and the support block 601 through the pin rod 604, so that the transformer housing is clamped and fixed by the two clamping arms 602; Secondly, in order not to affect the up and down movement of the press-fit structure 2, during the process of press-fitting the transformer coil from between the three clamping rods 301 into the inside of the transformer housing, the two clamping arms 602 hold the transformer housing tightly, such as Figure 6 and Figure 7 As shown, first threaded rods 205 are processed on both side surfaces of the top of the sliding back plate 208, and second strip grooves 12 are opened on both sides of the bottom of the support plate seat 202. By making the two first threaded rods 205 pass through the inside of the two second strip grooves 12 respectively, and threading the first nut 204 at one end of the first threaded rod 205, the sliding back plate 208 can be placed on the bottom surface of the support plate seat 202. When the support plate seat 202 is controlled to move up and down by the vertical screw rod assembly 1, the pressing plate 201 is driven to move up and down to press the transformer coil into the inside of the transformer housing. Because the first threaded rod 205 on the sliding back plate 208 is inside the second strip groove 12, the sliding back plate 208 can rely on its own gravity to maintain a state of being located at the top of the bearing platform 7, which is conducive to ensuring that the seat block 207 is stably supported between the two driving rods 603, and the driving rod 603 controls the clamping arm 602 to hold the transformer housing tightly through the pin rod 604; Furthermore, in order to enable one end of the press-fit plate 201 to press-fit transformer coils of different lengths into the interior of the transformer housing, Figure 7 As shown, positioning bolts 209 are provided inside both sides of the fixing seat 203, and a plurality of longitudinally arranged positioning threaded holes 13 are processed on both sides of the top of the support plate seat 202. By threading one end of the positioning bolts 209 into the positioning threaded holes 13 at different heights, the position of the press-fit plate 201 inside the support plate seat 202 can be controlled as required to control the movable height of the press-fit plate 201. At the same time, by adjusting the distance between the two support blocks 601 assembled to the top of the bearing platform 7, the angle of the two clamping arms 602 to embrace the transformer coil can be controlled according to the diameter of the transformer coil, so as to finally adapt to transformer coils of different diameters; In some examples, a second threaded rod 212 is processed at the center of the side of the leaning seat block 207 away from the inclined surface, a first guide rod 210 is processed at the top and bottom of the side of the leaning seat block 207, and a first spring 206 is sleeve-connected to the outside of the second threaded rod 212; Among them, by allowing one end of the second threaded rod 212 to pass through the bottom of the sliding back plate 208 and threadably connect the second nut 211, when the first spring 206 is supported between the sliding back plate 208 and the leaning seat block 207, the horizontal screw assembly 5 can drive the bearing platform 7 to drive the second clamping structure 6, so that the two driving rods 603 on one side of the second clamping structure 6 are in contact with the leaning seat block 207 at the bottom of the press-fitting structure 2, and the first spring 206 is compressed to the surface of the sliding back plate 208 (the first guide rod 210 is slidably connected to the inside of the sliding back plate 208), so as to avoid the two clamping arms 602 from applying a large pressure to the leaning seat block 207 through the two driving rods 603 when hugging the transformer housing, causing the sliding back plate 208 supporting the leaning seat block 207 to deform, thereby achieving the effect of elastic support.

[0025] Specifically, when the transformer coil press-fitting device is used to press-fit the transformer coil into the interior of the transformer housing: First, install the transformer coil from the top between the three clamping rods 301, and use the inclined rods on the three clamping rods 301 to guide it first, so that the clamping rods 301 compress the second spring 307 on one side of the first clamping support 304, and the transformer coil can be clamped and fixed after it moves to the vertical rods on the clamping rods 301; Then, the transformer housing is installed between the two clamping arms 602. When the horizontal screw assembly 5 drives the bearing platform 7 to drive the second clamping structure 6 to move to the bottom of the first clamping structure 3, the two driving rods 603 on the second clamping structure 6 contact the leaning seat block 207 at the bottom of the press-fitting structure 2. With the help of the inclined surface on the leaning seat block 207 and the inclined surface at one end of the driving rod 603, the two driving rods 603 slide inside the two supporting seat blocks 601 respectively and move away from each other, so that the driving rods 603 can control the clamping through the pin rod 604. The holding arm 602 rotates around the hinge point between the holding arm 602 and the supporting seat block 601. After the two clamping arms 602 clamp and fix the transformer housing (in this state, the transformer coil fixed by the three clamping rods 301 and the transformer housing are coaxial up and down), one end of the two driving rods 603 supports the leaning seat block 207, so that the leaning seat block 207 can compress the first spring 206 to avoid the rigid connection between the leaning seat block 207 and the sliding back plate 208. When receiving the pressure applied by the driving rod 603 to the leaning seat block 207, the sliding back plate 208 is broken. Subsequently, the vertical screw assembly 1 controls the support plate seat 202 on the press-fitting structure 2 outside the cross bar 11 to move toward the bottom. When the support plate seat 202 drives the press-fitting plate 201 to pass between two adjacent clamping rods 301, the transformer coil is pressed into the interior of the transformer housing. During the press-fitting process, the transformer coil and the press-fitting plate 201 will not slip (similar to the sliding connection state between the clamping rod 301 and the transformer coil). Since there is no obstruction on the inner side of the transformer coil, it is convenient for the transformer coil and the transformer housing to be quickly pressed, which is beneficial to improving the press-fitting efficiency.

[0026] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
