Description

Technical Field

[0001] The present invention relates to the technical field of transformer coil pressing, and specifically, it is a transformer coil pressing device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). The main functions of a transformer are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are basic power transmission and distribution equipment and are widely used in industries, agriculture, transportation, urban communities, and other fields.

[0003] As an indispensable part of a transformer, during the assembly of a transformer, first place the coil on the workbench of the pressing device, reasonably adjust the position according to the structure of the coil, then start the pressing device to start pressing the coil, and then control the pressing process according to the pressure and temperature displayed by the device to ensure uniform pressure and appropriate temperature. After completing the coil pressing, immediately conduct quality inspection.

[0004] In the patent document with the publication number CN116631767B, for a clamping assembly of a transformer coil integral sleeving device, when it extends to a position above the inner side surface 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 surface of the coil body. The anti-damage mechanism drives the coil body to a position above the transformer housing for sleeving, solving the problem that when using a hook to lift and sleeve the coil, the coil is prone to skew and cause the iron core to cut the coil cardboard.

[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0006] This transformer coil integral sleeving device uses the clamping assembly on the anti-damage mechanism to expand from the inside to the outside of the coil to clamp and fix the coil, which can prevent the coil from being damaged when related components are pressed onto the coil. However, in actual application, due to the presence of a support object blocking the inside of the coil, it is not easy to quickly complete the stamping work of the coil during pressing. Summary of the Invention

[0007] In order to overcome the deficiency that the existing overall sleeving equipment for transformer coils uses the clamping component on the anti-damage mechanism to expand from the inside to the outside of the coil to clamp and fix the coil. In the actual application process, due to the obstruction of the support on the inside of the coil, it is not easy to quickly complete the stamping work of the coil during press-fitting. The embodiment of the present application provides a transformer coil press-fitting device. By using three clamping rods to clamp and fix the transformer coil and using two clamping arms to hold the transformer housing tightly, a fixing effect can be achieved. When the vertical screw rod assembly controls the support plate seat to move downward, and the support plate seat drives the press-fitting plate to pass through between two adjacent clamping rods, the transformer coil can be press-fitted into the inside 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.

[0016] In a possible implementation, the second clamping structure includes two symmetrically arranged support seat blocks, driving rods are slidably connected inside the two support seat blocks, clamping arms are hingedly connected inside one corner of the two support seat blocks, a pin rod is pin-connected inside one end of the clamping arm, and a first strip-shaped groove is formed inside one end of the driving rod; the two clamping arms are arranged symmetrically left and right, the pin rod passes through the inside of the first strip-shaped groove, and the driving rod slides inside the support seat block, and the clamping arm is controlled to rotate around its hinge point with the support seat block through the pin rod.

On the other hand, by adjusting the distance between the two support seat blocks when assembled to the top of the bearing table plate, the angle at which the two clamping arms hold the transformer coil can be controlled according to the diameter of the transformer coil, so as to adapt to the pressing work of different types of transformer coils and the corresponding transformer housings.

[0041] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0042] Embodiment 1:

[0043] This embodiment introduces the specific structure of a transformer coil pressing device, specifically referring to Figures 1 - 5 As shown, it includes a vertical lead screw assembly 1 and a horizontal lead screw assembly 5 provided at the bottom of the vertical lead screw assembly 1 (the horizontal lead screw assembly 5 and the vertical lead screw assembly 1 use conventional means in the lead screw drive technology, which will not be elaborated here). A loading table board 7 is provided at the top of the horizontal lead screw assembly 5. A second clamping structure 6 is assembled and connected to the top of the loading table board 7. A pressing structure 2 is provided on the surface of the vertical lead screw assembly 1. A first clamping structure 3 is provided between the second clamping structure 6 and the pressing structure 2;

[0044] The bottom of the horizontal lead screw assembly 5 is assembled and connected to an equipment chassis 4. A gantry 9 is assembled and connected to the top of one side of the equipment chassis 4. Side plate frames 10 are assembled and connected to both ends of the gantry 9. Two cross bars 11 are assembled and connected between the two side plate frames 10. The vertical lead screw assembly 1 is assembled outside the two cross bars 11. The first clamping structure 3 is assembled between the two side plate frames 10 on the side away from the bottom of the gantry 9;

[0045] As Figures 3 - 5 shown, the first clamping structure 3 includes two plates 302. A connecting plate frame 303 is assembled and connected between one ends of the two plates 302. First clamping supports 304 are provided at the top of the center of the connecting plate frame 303 and at the top of one end of the two plates 302. Clamping rods 301 are provided on one side of the three first clamping supports 304;

[0046] Among them, by respectively assembling and fixing the other ends of the two plates 302 to one side surface of the two side plate frames 10 away from the bottom of the gantry (9), after arranging the three first clamping supports 304 and the three clamping rods 301 in a regular triangular arrangement, the transformer coil can be installed between the three clamping rods 301 from top to bottom, and the three clamping rods 301 are used to position the transformer coil;

[0047] At the same time, the three clamping rods 301 are integrally processed by a vertical upright rod and an inclined rod. When the transformer coil is installed and positioned between the three clamping rods 301, it can be guided by the inclined rod first and then positioned by the upright rod to ensure that the axis of the transformer coil is vertically downward;

[0048] Secondly, in order to enable the three clamping rods 301 to clamp and fix transformer coils with different diameters, as Figure 4 shown, a second spring 307 is provided between the clamping rod 301 and the first clamping support 304. A third threaded rod 305 is processed in the middle of the side of the clamping rod 301 close to the first clamping support 304. Second guide rods 306 are processed at both the top and bottom of the side of the clamping rod 301 close to the first clamping support 304. By slidingly connecting the second guide rods 306 inside 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 a 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, and it can adapt to a variety of transformer coils within a certain diameter range;

[0049] 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;

[0050] Among them, by passing both the third guide rod 311 and the fourth threaded rod 310 through the connecting plate frame 303 or through the inside of the plate 302, and threading a 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.

[0051] Embodiment 2:

[0052] Based on Embodiment 1, as Figures 1 - 3 、 Figures 6 - 8As shown, this embodiment introduces the specific structures of the second clamping structure 6 and the press-fitting structure 2. The second clamping structure 6 includes two symmetrically arranged support seat blocks 601. Inside both of the two support seat blocks 601, there is a driving rod 603 connected in a sliding manner. Inside one corner of each of the two support seat blocks 601, there is a clamping arm 602 connected in a hinged manner. Inside one end of the clamping arm 602, there is a pin rod 604 connected in a pin-jointed manner. Inside one end of the driving rod 603, there is a first strip-shaped groove 8;

[0053] Among them, by controlling the top of the press-fitting structure 2 to move from top to bottom by the vertical lead screw assembly 1, when the press-fitting plate 201 on the press-fitting structure 2 passes through between the three clamping rods 301, it can push the transformer coil fixed inside the first clamping structure 3 to move downward. When the transformer coil moves to the top of the transformer housing, it can enter the inside of the transformer housing;

[0054] As Figure 6 and Figure 7 shown, the press-fitting structure 2 includes a support plate seat 202. On the top of the support plate seat 202, there is a fixed seat 203. On one side surface of the fixed seat 203, there is a press-fitting plate 201 integrally formed. On one side of the bottom of the support plate seat 202, there is a sliding back plate 208. On one side of the bottom of the sliding back plate 208, there is a leaning seat block 207;

[0055] Among them, the leaning seat block 207 is located at the bottom of the support plate seat 202. One end of each of the two driving rods 603 is processed with an inclined surface. The cross-section of the leaning seat block 207 is an isosceles trapezoid. The two clamping arms 602 are symmetrically arranged left and right. The pin rod 604 passes through the inside of the first strip-shaped groove 8. When the horizontal lead screw assembly 5 drives the carrier plate 7 to drive the second clamping structure 6, and the transformer housing located inside 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 the bottom of the press-fitting structure 2. With the support of the leaning seat block 207, the inclined surface on the leaning seat block 207 can cooperate with the inclined surface at one end of the driving rod 603, causing the driving rod 603 to slide inside the support seat block 601 (the two driving rods 603 move away from each other), and controlling the clamping arm 602 to rotate around its hinge point with the support seat block 601 through the pin rod 604, so as to clamp and fix the transformer housing with the two clamping arms 602;

[0056] Secondly, in order not to affect the up and down movement of the press-fitting structure 2, during the process of pressing the transformer coil from between the three clamping rods 301 into the transformer housing, the two clamping arms 602 tightly hold the transformer housing, as Figure 6 and Figure 7As shown, first threaded rods 205 are machined on both side surfaces at the top of the sliding back plate 208, and second strip-shaped grooves 12 are formed on both sides at the bottom of the support plate seat 202. By passing the two first threaded rods 205 through the interiors of the two second strip-shaped grooves 12 respectively and threading first nuts 204 onto one ends of the first threaded rods 205, the sliding back plate 208 can be positioned on the bottom surface of the support plate seat 202. When the support plate seat 202 moves up and down under the control of the vertical lead screw assembly 1, driving the pressing plate 201 to move up and down to press-fit the transformer coil into the transformer housing, since the first threaded rods 205 on the sliding back plate 208 are inside the second strip-shaped grooves 12, the sliding back plate 208 can maintain its position on top of the bearing plate 7 by virtue of its own gravity, which helps ensure that the leaning seat block 207 is stably supported between the two driving rods 603 and that the driving rods 603 control the clamping arms 602 to tightly hold the transformer housing through the pin rods 604;

[0057] Furthermore, in order to enable one end of the pressing plate 201 to press-fit transformer coils of different lengths into the transformer housing, as Figure 7 shown, positioning bolts 209 are provided inside both sides of the fixed seat 203, and a plurality of longitudinally arranged positioning threaded holes 13 are machined on both sides at the top of the support plate seat 202. By threadedly connecting one end of the positioning bolt 209 to the positioning threaded holes 13 at different heights, the position of the pressing plate 201 inside the support plate seat 202 can be controlled according to requirements to control the height at which the pressing plate 201 can move;

[0058] Meanwhile, by adjusting the distance between the two support seat blocks 601 when assembled on top of the bearing plate 7, the angle at which the two clamping arms 602 hold 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;

[0059] In some examples, a second threaded rod 212 is machined at the center of the leaning seat block 207 on the side away from the inclined surface, and first guide rods 210 are machined at the top and bottom of one side of the leaning seat block 207. A first spring 206 is sleeved on the outside of the second threaded rod 212;

[0060] Among them, by passing one end of the second threaded rod 212 through the bottom of the sliding back plate 208 and threadedly connecting the second nut 211, when the first spring 206 is supported between the sliding back plate 208 and the leaning seat block 207, when the horizontal screw rod assembly 5 drives the bearing table plate 7 to drive the second clamping structure 6, and the two driving rods 603 on one side of the second clamping structure 6 contact the leaning seat block 207 at the bottom of the pressing structure 2 and compress the first spring 206 to the surface of the sliding back plate 208 (the first guide rod 210 is slidably connected inside the sliding back plate 208), it is possible to avoid applying a large pressure to the leaning seat block 207 through the two driving rods 603 when the two clamping arms 602 hold the transformer housing tightly, resulting in deformation of the sliding back plate 208 that supports the leaning seat block 207, thereby achieving the effect of elastic support.

[0061] Specifically, when using this transformer coil pressing device to press the transformer coil into the interior of the transformer housing:

[0062] First, install the transformer coil between the three clamping rods 301 from the top, and use the inclined rods on the three clamping rods 301 for guiding first, so that the clamping rods 301 compress the second spring 307 on one side of the first clamping support 304, and after the transformer coil moves to the vertical rod on the clamping rod 301, it can be clamped and fixed.

[0063] Then, install the transformer housing between the two clamping arms 602. When the horizontal screw rod assembly 5 drives the bearing table plate 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 pressing structure 2. By means of the cooperation between 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 support seat blocks 601 respectively and move away from each other, so that the driving rod 603 can control the clamping arm 602 to rotate around its hinge point with the support seat block 601 through the pin rod 604. 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 coaxially arranged 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, avoiding the rigid connection between the leaning seat block 207 and the sliding back plate 208, and breaking the sliding back plate 208 when receiving the pressure applied by the driving rod 603 to the leaning seat block 207.

[0064] Subsequently, the vertical lead screw assembly 1 controls the support plate seat 202 on the external pressing structure 2 of the cross bar 11 to move downward. When the support plate seat 202 drives the pressing plate 201 through the space between two adjacent clamping rods 301, the transformer coil is pressed into the interior of the transformer housing. During the pressing process, there will be no slippage between the transformer coil and the pressing plate 201 (similar to the sliding connection state between the clamping rod 301 and the transformer coil). Moreover, since there is no obstruction inside the transformer coil, it is conducive to quickly completing the pressing of the transformer coil and the transformer housing, which is beneficial to improving the pressing efficiency.

[0065] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, 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 manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
