Description

Technical Field

[0001] The utility model relates to the technical field of transformer production and processing, in particular to a turnover device for transformer semi-finished products. 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. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. It can be classified by use as: power transformers and special transformers (such as furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mine transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impulse transformers, instrument transformers, electronic transformers, reactors, and current transformers). During the production process of transformers, the assembly of magnetic cores needs to be completed, which requires the turnover and assembly of transformer semi-finished products.

[0003] The turnover device of the existing transformer production equipment has a simple structure. It clamps the middle part of the semi-finished product by two clamping arms facing each other and then implements turnover. However, due to the relatively large mass of the semi-finished product itself after the assembly of the iron core, coil, skeleton, etc., the turnover device is not firmly grasped during the turnover process and is prone to falling off. In addition, except for the clamping part of the existing turnover device that clamps the semi-finished product to implement turnover, other structural components cannot move, and the adaptability and versatility in cooperating with other equipment on the transformer production line are relatively poor.

[0038] The following combines the attached Figures 1 to 4 drawings and further illustrates the technical solution of the present utility model through specific embodiments.

[0039] A turnover device for a transformer semi-finished product, comprising a base 1, a mounting seat 2, a rotary drive assembly 3, an L-shaped support seat 41, a lower clamping sub-assembly 42, an upper clamping sub-assembly 43, and a front and rear drive assembly 5;

[0040] The mounting seat 2 is installed on the upper part of the base 1, the rotary drive assembly 3 and the L-shaped support seat 41 are respectively installed on the mounting seat 2, and the rotary drive assembly 3 is used to drive the L-shaped support seat 41 to turn up and down; the front and rear drive assembly 5 is used to drive the base 1 to move forward and backward;

[0041] The lower clamping sub-assembly 42 and the upper clamping sub-assembly 43 are respectively installed on the L-shaped support seat 41, the upper clamping sub-assembly 43 is located above the lower clamping sub-assembly 42, the lower clamping sub-assembly 42 is used to clamp and fix the lower part of the workpiece, and the upper clamping sub-assembly 43 is used to tightly press against the top of the workpiece downward.

[0042] The utility model provides a turnover device for semi-finished transformers, which is used to clamp and fix the semi-finished products obtained during the assembly and manufacturing process of transformers (hereinafter collectively referred to as "workpieces"), and turnover the workpieces to carry out the assembly and inspection of other components. The utility model forms a clamping assembly by installing the lower clamping sub-assembly 42 and the upper clamping sub-assembly 43 on the L-shaped support base 41, and the clamping assembly can clamp and fix the upper and lower parts of the semi-finished transformer at the same time.

[0043] Specifically, during the production process, the workpiece is placed on the L-shaped support base 41, and the lower clamping sub-assembly 42 clamps and fixes the lower part of the workpiece, playing a role of preliminary clamping and fixing; subsequently, the upper clamping sub-assembly 43 acts on the top of the workpiece and applies a downward force against the top of the workpiece, so that the workpiece is clamped between the upper clamping sub-assembly 43 and the L-shaped support base 41 with upper and lower limits, avoiding the workpiece from disengaging from the clamping assembly from above during the turnover process; after the clamping operation is completed, the rotation drive assembly 3 drives the L-shaped support base 41 to turn up and down, and then the subsequent assembly or inspection of the workpiece can be carried out. This way of clamping the upper and lower parts of the workpiece respectively, on the one hand, effectively disperses the gravity of the workpiece, enhances the clamping stability, and reduces the risk of falling caused by the large mass of the workpiece during the turnover process; on the other hand, the lower clamping sub-assembly 42 and the upper clamping sub-assembly 43 do not act on the middle part of the workpiece, avoiding damage to the workpiece during the clamping and turnover process. At the same time, the clamping assembly avoids the accessories and assembly stations in the middle of the workpiece, making it more convenient for the subsequent processing or observation and inspection of the workpiece.

[0044] The front and rear drive assembly 5 enables the entire turnover device to move back and forth under the drive of the base 1. This not only improves the flexibility of the device on the production line, enables it to better adapt to the requirements of different positions and spatial layouts, but also enhances the cooperation ability with other production equipment, improving the overall efficiency and automation level of the production line. The rotation drive assembly 3 and the L-shaped support base 41 are installed on the mounting base 2 instead of directly on the base, effectively reducing the influence of the front and rear movement of the base driven by the front and rear drive assembly 5 on the rotation drive assembly 3 and the L-shaped support base 41; and the rotation drive assembly 3 and the L-shaped support base 41 are both installed on the mounting base 2, making the turnover action more direct and accurate, improving the stability and accuracy of the turnover, and ensuring the safety and integrity of the semi-finished transformer during the turnover process.

[0045] The turnover device of the utility model fully considers the characteristics and production requirements of the semi-finished transformer in terms of design and function, making the entire turnover process smoother and more efficient. At the same time, by enhancing the clamping stability and improving the turnover accuracy and stability, it also effectively reduces the possible accidents and safety hazards during the production process, providing a safer and more reliable working environment for production personnel.

[0046] Further, the front and rear drive assembly 5 includes a slide rail base, a first driver 51, a first slide rail 52, a first slider 53, and a connecting rod 54;

[0047] The first driver 51 is installed on the slide rail base. One end of the connecting rod 54 is connected to the driving end of the first driver 51, and the other end of the connecting rod 54 is connected to the base 1. The first driver 51 is used to drive the connecting rod 54 and the base 1 to move in the front-rear direction;

[0048] The first slide rail 52 is installed on the slide rail base in the front-rear direction. The first slider 53 is installed at the bottom of the base 1, and the first slider 53 is slidably connected to the first slide rail 52 in a matching manner.

[0049] By introducing the front and rear drive assembly 5 composed of a slide rail base, a first driver 51, a first slide rail 52, and a first slider 53, the base 1 can move along a preset track when moving back and forth, avoiding the offset or shaking problems that may occur in the traditional method. This linear sliding design greatly improves the stability of the front-rear movement and also enhances the accuracy of the movement, ensuring that the flipping device can accurately move to the designated position.

[0050] The slidable connection in a matching manner between the first slide rail 52 and the first slider 53 not only reduces the friction and wear during the movement but also reduces the noise and vibration. Since the design of the front and rear drive assembly 5 enables the base 1 to move flexibly in the front-rear direction, the flipping device can better adapt to different production line layouts and space limitations. Whether it is a compact production line or a large production workshop, the device can easily handle it, improving the flexibility and adaptability of the production line. By seamlessly docking with other automated devices (such as robots, conveyor belts, etc.) on the production line, the full-automatic processing of the transformer semi-finished product from processing to flipping and then to the next process is realized, improving the overall efficiency and intelligent level of the production line.

[0051] Furthermore, a front limit block 55 and a rear limit block 56 are respectively provided at the front end and the rear end of the slide rail base. The front limit block 55 and the rear limit block 56 are used to limit the movement of the base 1 in the front-rear direction.

[0052] Through the precise setting of the front limit block 55 and the rear limit block 56, it can be ensured that the base 1 can accurately stop at the predetermined position after moving in place. This precise positioning not only improves the accuracy of the flipping operation but also ensures the smooth progress of the subsequent processing or assembly processes. At the same time, the presence of the limit blocks also enhances the stability of the base 1 in the stationary state, preventing accidental movement caused by external factors (such as vibration, impact, etc.), improving the safety of the device, and ensuring the stable operation of the production equipment.

[0053] Further, the base 1 includes a base bottom plate 11 and two base vertical plates 12. The base bottom plate 11 is horizontally arranged, and the two base vertical plates 12 are respectively installed at both ends of the top surface of the base bottom plate 11, and the two base vertical plates 12 extend vertically upward;

[0054] The mounting seat 2 includes a mounting bottom plate 21 and two mounting vertical plates 22. The mounting bottom plate 21 is horizontally arranged, and the two mounting vertical plates 22 are respectively installed at both ends of the top surface of the mounting bottom plate 21, and the two mounting vertical plates 22 extend vertically upward. The lower parts of the two mounting vertical plates 22 at both ends are detachably connected to the upper parts of the two base vertical plates 12 at both ends.

[0055] The detachable connection between the base 1 and the mounting seat 2 makes the maintenance and upgrade of the equipment easier. When cleaning, repairing or replacing components are needed, the relevant parts can be conveniently disassembled without disassembling the whole equipment. In addition, this design also facilitates adjusting the layout and configuration of the equipment according to production requirements, improving the flexibility of the equipment.

[0056] The base 1 is composed of a base bottom plate 11 and two base vertical plates 12, forming a stable support structure. Similarly, the mounting seat 2 also adopts a similar design, ensuring the stable installation of key components such as the rotary drive assembly 3 and the clamping assembly. This stable support structure not only improves the overall stability of the equipment, but also enhances its load-bearing capacity, enabling the equipment to safely and reliably process heavier and larger semi-finished transformers.

[0057] Further illustration, the upper parts of the two mounting vertical plates 22 at both ends and the upper parts of the two base vertical plates 12 at both ends can be installed and connected by opening mounting holes and using screws. By opening a number of vertically arranged mounting holes on the mounting vertical plates 22 and the base vertical plates 12, the height of the mounting seat 2 can be adjusted according to production needs, improving the applicability of the flipping equipment.

[0058] Furthermore, a height adjustment component is further included. The height adjustment component includes a vertical adjustment rod 61, an upper nut 62 and a lower nut;

[0059] One end of the vertical adjustment rod 61 is fixed to the base bottom plate 11. The rod body of the other end of the vertical adjustment rod 61 is provided with threads. The other end of the vertical adjustment rod 61 vertically penetrates through the mounting bottom plate 21. The lower nut is threadedly connected to the vertical adjustment rod 61 and is located at the bottom of the mounting bottom plate 21. The upper nut 62 is threadedly connected to the vertical adjustment rod 61 and is located at the top of the mounting bottom plate 21.

[0060] The setting of the height adjustment component enables the device to adjust the height of the mounting base 2 relative to the base 1 according to actual needs, enhancing the adaptability and flexibility of the device. At the same time, it also facilitates quick adjustment on the production line to meet different production requirements. Specifically, by rotating the upper nut 62 and the lower nut to adjust the height of the mounting base 2, the height of the L-shaped support base 41 can be adjusted. During maintenance, if components need to be replaced or repaired, it can also be conveniently achieved by adjusting the height.

[0061] Furthermore, the rotation drive assembly 3 includes a second driver 31, a driving wheel 32, a driven wheel 33, a transmission belt 34, and a transmission rod 35.

[0062] The fixed end of the second driver 31 is mounted on the mounting base 2. The driving wheel 32 and the driven wheel 33 are rotatably mounted on the mounting base 2. The transmission belt 34 is wound around the outer sides of the driving wheel 32 and the driven wheel 33. The driving wheel 32 is connected to the output end of the second driver 31.

[0063] One end of the transmission rod 35 is fixedly connected to the driven wheel 33, and the other end of the transmission rod 35 is connected to the L-shaped support base 41. The second driver 31 drives the L-shaped support base 41 to flip up and down through the driving wheel 32, the driven wheel 33, the transmission belt 34, and the transmission rod 35.

[0064] The second driver 31 serves as a power source. Through the transmission of the driving wheel 32, the driven wheel 33, and the transmission belt 34, the driving force is efficiently transmitted to the transmission rod 35 and the L-shaped support base 41. This transmission method has a high transmission efficiency and can quickly realize the flipping operation of the semi-finished transformer, improving the overall efficiency of the production line. By adopting the transmission method of the driving wheel 32, the driven wheel 33, and the transmission belt 34, the stable transmission of the rotational driving force is achieved, improving the flipping stability and accuracy, enhancing the reliability and durability of the device, and simplifying the driving structure to reduce costs.

[0065] Even further, the rotation drive assembly 3 further includes a tensioning wheel 36. The tensioning wheel 36 is rotatably mounted on the mounting base 2, and the wheel surface of the tensioning wheel 36 contacts the outer surface of the transmission belt 34.

[0066] The main function of the tensioning wheel 36 is to adjust the tension of the transmission belt 34 to ensure that it is in an appropriate taut state. This helps to prevent the transmission belt 34 from slipping or becoming loose during operation, thereby improving the stability and reliability of the rotation drive assembly 3. A stable transmission belt can transmit the driving force more accurately, ensuring the accuracy and stability of the flipping operation.

[0067] Further, the L-shaped support base 41 includes a first horizontal plate 411, a vertical plate 412, and a second horizontal plate 413. The first horizontal plate 411 and the second horizontal plate 413 are parallel to each other. The lower end and the upper end of the vertical plate 412 are respectively connected to the rear end of the first horizontal plate 411 and the rear end of the second horizontal plate 413;

[0068] The lower clamping sub-assembly 42 is installed at the front end of the first horizontal plate 411, and the upper clamping sub-assembly 43 is installed at the top of the second horizontal plate 413.

[0069] By designing the L-shaped support base 41 as a double-layer structure (i.e., the first horizontal plate 411, the vertical plate 412, and the second horizontal plate 413), and installing the lower clamping sub-assembly 42 and the upper clamping sub-assembly 43 on horizontal plates at different levels respectively, the clamping points are distributed at different heights, clamping and fixing different positions of the workpiece, which helps to better disperse and balance the weight of the transformer semi-finished product during the flipping process, improve the clamping stability, and reduce the shaking or tilting caused by uneven weight.

[0070] Furthermore, the lower clamping sub-assembly 42 includes a lower clamping driver 421, two clamping plates 422, and a bottom plate. The lower clamping driver 421 and the bottom plate are installed at the rear end of the first horizontal plate 411. The bottom plate is horizontally arranged and used for placing the workpiece. The clamping plates 422 extend upward. The two clamping plates 422 are parallel to each other and arranged oppositely. The lower clamping driver 421 is used to drive the two clamping plates 422 to move closer to or away from each other.

[0071] The bottom plate is horizontally arranged and used for placing the workpiece, providing a stable support surface for the workpiece. The two clamping plates 422 are parallel to each other and arranged oppositely, forming a stable clamping structure. During the clamping process, the two clamping plates 422 can apply clamping forces simultaneously and evenly, avoiding the problems of workpiece tilting or slipping that may be caused by single-point clamping, and further improving the clamping stability. By introducing the lower clamping driver 421 to drive the two clamping plates 422 to move closer to or away from each other, more precise and controllable clamping of the lower part of the workpiece is achieved.

[0072] Furthermore, the upper clamping sub-assembly 43 includes an upper clamping driver 431, a clamping arm 432, a support 433, a rack 434, a gear 435, a second slide rail 436, and a second slider 437. The upper clamping driver 431, the support 433, and the second slide rail 436 are arranged on the top surface of the second horizontal plate 413;

[0073] The second slide rail 436 is arranged to extend in the front-rear direction. The second slider 437 is slidably connected with the second slide rail 436 in a matching manner. The rack 434 is arranged on the second slider 437 in the front-rear direction. The second slider 437 is connected to the driving end of the upper clamping driver 431. The upper clamping driver 431 is used to drive the second slider 437 and the rack 434 to move back and forth.

[0074] The support 433 extends vertically upward. The gear 435 is installed at one end of the clamping arm 432. One end of the clamping arm 432 where the gear 435 is provided is hinged to the support 433. The gear 435 meshes with the rack 434.

[0075] Components such as the upper clamping driver 431, the support 433, and the second slide rail 436 are reasonably arranged on the top surface of the second horizontal plate 413 to limit and clamp the upper part / top of the workpiece. On the one hand, the clamping part of the upper clamping sub-component 43 is optimized. On the other hand, the spatial layout of the functional components of the equipment is optimized, and there is no interference between them.

[0076] The upper clamping driver 431 drives the second slider 437 and the rack 434 to move back and forth along the second slide rail 436. Then, through the meshing relationship between the gear 435 and the rack 434, the rotation of the clamping arm 432 is realized. When the clamping arm 432 rotates and moves to abut against the top of the workpiece, downward pressure is applied to cooperate with the bottom plate of the lower clamping sub-component 42 to clamp the workpiece up and down.

[0077] The technical principle of the present utility model has been described in combination with specific embodiments above. These descriptions are only for explaining the principle of the present utility model and cannot be construed as any limitation to the protection scope of the present utility model in any way. Based on the explanations herein, those skilled in the art can think of other specific embodiments of the present utility model without creative labor, and these embodiments will fall within the protection scope of the present utility model.
