Description
Technical Field
[0001] This utility model relates to the field of press-fitting, and in particular to a transformer coil press-fitting device. Background Technology
[0002] The upper end face of the transformer coil 20 needs to be installed in a bracket, which includes an upper bracket 18 and a lower bracket 19. The upper bracket 18 and the lower bracket 19 are secured together by four screws 15 and nuts 14. The upper bracket 18 and the lower bracket 19 need to be completely flush against the upper and lower end faces of the transformer coil 20 before the transformer, installed in the bracket, is transported to the press 8 for pressing. However, the transformer coil 20 is relatively heavy and large, making it difficult for operators to completely and securely fasten the upper bracket 18 and the lower bracket 19 to the upper and lower end faces of the transformer coil 20. It is also difficult for operators to move the transformer coil 20, installed in the bracket, to the press 8. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a transformer coil pressing device that facilitates the installation of upper and lower supports on transformer coils by operators, as well as the pressing process.
[0004] To achieve the above objectives, one technical solution adopted by this utility model is: a transformer coil pressing device, including a front-end frame, a rear-end frame, and further comprising: A pair of first drive chains are mounted on the front-end frame, and the first drive chains are driven by a motor; The first end baffle is fixedly installed at the beginning of the pair of first transmission chains and is higher than the first transmission chains; A third drive chain is installed on the rear rack, the third drive chain is driven by a motor, and the third drive chain is at the same height as the first drive chain; The press has a base located between a front frame and a rear frame. A hydraulic cylinder is mounted on the base, and a lifting frame is fixedly mounted on the top of the hydraulic cylinder. A pair of second drive chains are mounted on the lifting frame. The second drive chains are driven by a motor. The pair of second drive chains are located between a first drive chain and a third drive chain. A press support seat lower than the first drive chain is provided on the base between the pair of second drive chains. The second drive chains can be raised to be flush with the first drive chain and the third drive chain respectively, or lowered to be lower than the press support seat, driven by the hydraulic cylinder. The second end baffle is fixedly installed at the end of the pair of third transmission chains and is higher than the third transmission chains.
[0005] The beneficial effects of this utility model of transformer coil pressing equipment are: The pre-installed transformer coil and bracket are moved onto the first drive chain by a crane. The first drive chain then transmits the transformer coil with the bracket to the second drive chain until it is directly above the press support. The press cylinder drives the press plate to move down, pressing the upper bracket down until it is in contact with the upper end face of the transformer coil, while the lower bracket remains on the lower end face of the transformer coil. The upper and lower brackets are completely in contact with the upper and lower end faces of the transformer coil. The upper bracket is locked onto the screw with a nut, completing the locking and installation of the bracket. Afterward, the press is reset and the second drive chain transmits the coil to the third drive chain. Finally, the crane removes the coil from the third drive chain. This technical solution facilitates the installation of the upper and lower brackets on the transformer coil by operators, enabling complete fitting and pressing.
[0006] Preferably, the system further includes three pairs of side guide assemblies. These three pairs of side guide assemblies are respectively fixedly installed on the outside of a pair of first drive chains, a pair of second drive chains, and a pair of third drive chains, and are higher than their corresponding drive chains. The pair of side guide assemblies corresponding to the second drive chain is fixedly installed on the lifting frame. The three pairs of side guide assemblies are used to guide the running transformer coils and supports, ensuring the accurate running path of the transformer coils.
[0007] Preferably, each pair of side guide assemblies includes two side guide assemblies, and each side guide assembly includes: The side plate frame is perpendicular to the horizontal plane, and the inner side of the side plate frame is provided with a mounting groove. The side plate frame is higher than the corresponding transmission chain. Multiple guide rollers, each of which is perpendicular to the horizontal plane, are rotatably mounted in the mounting groove via a rotating shaft; The outer surfaces of multiple guide rollers on the same side of the side guide assembly are on the same plane.
[0008] The guide rollers are rotatable, which not only guides the transformer coils but also reduces friction, thus facilitating their movement.
[0009] Preferably, the upper surface of the side plate frame is a guide slope to guide the transformer coil in the vertical direction.
[0010] Preferably, each of the side panel frames is provided with sensors at both ends to sense whether it is in position.
[0011] Preferably, each of the side guide components is provided with a button box switch for starting the motor, and the button box switch includes an emergency stop switch, a forward switch, and a reverse switch.
[0012] Preferably, the bottom of the base is provided with multiple reinforcing ribs to ensure the supporting strength of the base. Attached Figure Description

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0016] See Figures 1-9 As shown, this embodiment discloses a transformer coil pressing device that facilitates the installation of the upper bracket 18 and lower bracket 19 onto the transformer coil 20 by operators, and includes a front frame 1, a rear frame 21, and further includes: A pair of first drive chains 2 are mounted on the front frame 1, and the first drive chains 2 are driven by a motor; The first end baffle 3 is fixedly installed at the beginning of a pair of first transmission chains 2 and is higher than the first transmission chains 2; The third drive chain 9 is installed on the rear frame 21. The third drive chain 9 is driven by a motor and is at the same height as the first drive chain 2. The press 8 has a base 17 located between the front frame 1 and the rear frame 21. A hydraulic cylinder 6 is installed on the base 17, and a lifting frame 5 is fixedly installed on the top of the hydraulic cylinder 6. A pair of second transmission chains 4 are installed on the lifting frame 5. The second transmission chains 4 are driven by a motor. The pair of second transmission chains 4 are located between the first transmission chain 2 and the third transmission chain 9. A press support seat 7 lower than the base 17 is provided on the base 17 between the pair of second transmission chains 4. The second transmission chains 4 can be driven by the hydraulic cylinder 6 to rise to be flush with the first transmission chain 2 and the third transmission chain 9 respectively, or to fall below the press support seat 7. The second end baffle 10 is fixedly installed at the end of a pair of third transmission chains 9 and is higher than the third transmission chains 9; Three pairs of side guide assemblies 11 are respectively fixedly installed on the outside of a pair of first transmission chains 2, a pair of second transmission chains 4, and a pair of third transmission chains 9, and are higher than their corresponding transmission chains. The pair of side guide assemblies 11 corresponding to the second transmission chain 4 are fixedly installed on the base 17.
[0017] like Figures 7 to 9 As shown, each pair of side guide assemblies 11 includes two side guide assemblies 11, and each side guide assembly 11 includes: The side plate frame 11a is perpendicular to the horizontal plane. The inner side of the side plate frame 11a is provided with a mounting groove 11b. The side plate frame 11a is higher than the corresponding transmission chain. In this embodiment, the upper end surface of the side plate frame 11a is a guide slope 11d.
[0018] Multiple guide rollers 11c, each guide roller 11c being perpendicular to the horizontal plane, are rotatably mounted in the mounting groove 11b via a rotating shaft; The outer surfaces of multiple guide rollers 11c on the same side of the side guide assembly 11 are on the same plane.
[0019] Each side panel frame 11a is equipped with a sensor 12 at both ends to detect whether it is in position.
[0020] Each side guide assembly 11 is equipped with a starter switch 13 for the motor. The starter switch 13 includes an emergency stop switch, a forward switch, and a reverse switch. In this embodiment, the press switch and hydraulic cylinder switch are not on the line body, but are controlled by the touch screen of the line body. The touch screen is connected to the controller, which is in turn connected to the press and hydraulic cylinder switches. The controller is prior art and will not be described again. Furthermore, this solution is not the one that this application seeks to protect.
[0021] The base 17 has multiple reinforcing ribs 16 at its bottom to ensure the support strength of the base 17.
[0022] The working principle of this embodiment is as follows: The pre-installed transformer coil 20 and bracket are moved onto the first drive chain 2 using a crane. The pre-installed state is as follows: the upper bracket 18 and lower bracket 19 are installed on the upper and lower end faces of the transformer coil 20, respectively. The lower bracket 19 is threadedly connected to four screws 15, and the four nuts 14 of the upper bracket 18 are locked onto the screws 15. Figure 5 As shown, the upper bracket 18 is not attached to the upper surface of the transformer coil 20. The transformer coil 20 and the bracket are limited by a pair of side guide components 11 on both sides of the first transmission chain 2, and the ends are limited by the first end baffle 3. When the position is correct, and the two sensors 12 corresponding to the first transmission chain 2 sense both ends of the product, it indicates that the position is correct. The button box switch 13 of the first transmission chain 2 is activated, and the first transmission chain 2 moves the product to the second transmission chain 2. The button box switch 13 of the second transmission chain 2 is then activated until the two sensors 12 corresponding to the second transmission chain 2 sense the transformer coil 20 and the bracket. After the position is correct, the second transmission chain 2 stops running, the hydraulic cylinder switch is activated, and the lifting frame 5 is lowered until the second transmission chain 4 on the lifting frame 5 is lower than the press support seat 7. After the photoelectric switch of the transformer coil pressing equipment line senses the position, the press switch is activated, and the oil of the press 8 is turned on. The cylinder-driven press 8 moves its pressure plate downward, pressing the upper bracket 18 down until it is in contact with the upper end face of the transformer coil 20 (the upper bracket 18 is provided with a smooth through hole for the screw 15 to pass through, so that the upper bracket 18 can slide along the screw 15, and the connection between the upper bracket 18 and the screw 15 is fixed by the nut 14), while the lower bracket 19 is always on the lower end face of the transformer coil 20. The upper bracket 18 and the lower bracket 19 are completely in contact with the upper end face and the lower end face of the transformer coil 20. The upper bracket 18 is locked to the screw 15 by the nut 14, completing the locking and installation of the bracket. After that, the press 8 is reset and transmitted to the third transmission chain 9 by the second transmission chain 4. Finally, the crane removes the third transmission chain 9. With this technical solution, it is convenient for operators to completely fit and install the upper bracket 18 and the lower bracket 19 on the transformer coil 20 and to achieve pressing.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
