Description

Technical Field

[0001] The utility model relates to the technical field of transformer production, in particular to a pin correction device for transformer production. Background Art

[0002] Transformer is the basic equipment for power transmission and distribution, which can be widely used in industry, agriculture, transportation and other fields. Its main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. The transformer structure includes a transformer body and pins connected to the bottom of the transformer body. When the transformer pins are bent or skewed during production, the transformer pins need to be corrected to ensure the normal use of the transformer. Therefore, a pin correction device is needed. For this purpose, China has authorized a utility model patent (Announcement No.: CN220065416U) to disclose a new transformer pin correction device. Through the operation of the third electric telescopic rod, the clamping plate will move outward inside the movable plate, and then the transformer can be automatically clamped. Through the operation of the second electric telescopic rod, the slider will slide inside the slide groove, so that the movable plate can be moved downward, and the transformer pins can be automatically reciprocated to the inside of the correction hole to realize the correction work.

[0003] The above-mentioned device still has some shortcomings when in use: an adjustment mechanism is provided in each correction hole in the above-mentioned device, and each adjustment structure includes a first electric push rod, so the number of first electric push rods used is relatively large, resulting in a relatively high cost of the entire device. When the first electric push rod inside the correction hole fails, its maintenance and replacement process is relatively difficult, which not only affects the production efficiency, but also has an adverse effect on the normal operation of the production line. Therefore, in view of the above situation, a pin correction device for transformer production is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that each adjustment structure includes a first electric push rod, so a relatively large number of first electric push rods are used, resulting in a relatively high cost of the entire device, and to propose a pin correction device for transformer production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pin correction device for transformer production comprises a correction plate. Two rows of correction holes are provided on the correction plate, and the number of correction holes in each row is three.

[0007] A rectangular groove is provided on the correction plate, and a pair of first electric push rods are provided on the rectangular groove and the correction plate, and a driving rod is fixedly connected to the moving end of each first electric push rod.

[0008] The top surface of the correction plate is staggered with movable grooves connected to the correction holes, and a support rod is slidably fitted in the movable groove. The end of the support rod located in the correction hole is fixedly connected to the adjustment plate, and the end of the adjustment plate away from the support rod is fixedly connected to the driving rod.

[0009] Preferably, a pair of vertical plates are provided on the top of the correction plate, and positioning pieces are slidably fitted on the vertical plates.

[0010] Preferably, the vertical plate is in an inverted "L" shape, a cylinder is provided on the top of the vertical plate, and a piston rod of the cylinder passes through the vertical plate and is connected to the top of the positioning member.

[0011] Preferably, a slide groove is provided in the movable groove, and a rectangular block is provided at the bottom of the support rod, and the rectangular block is slidably matched with the slide groove.

[0012] Preferably, three support rods are fixedly connected to the driving rod, and the top surface of each support rod is in the same horizontal plane as the top surface of the correction plate.

[0013] Preferably, four supporting columns are arranged at the bottom of the correction plate.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model connects all the adjustment plates in the same row to the driving rod through the structural design of the support rod, the electric push rod and the driving rod, and performs synchronous operation after being driven by the electric push rod, thereby significantly reducing the number of electric push rods used, which not only reduces the production cost, but also makes the structure of the device more compact and improves the space utilization rate. At the same time, the electric push rod is arranged outside the correction hole, so that when a fault occurs, the maintenance and replacement process of the electric push rod is more convenient, which not only reduces the maintenance time and improves the production efficiency, but also reduces the maintenance cost.

[0016] 2. The utility model ensures the stability of movement during the movement of the support rod through the structural design of the moving groove and the sliding groove. At the same time, the support rod moves in the moving groove so that the support rod and the top surface of the correction plate are on the same horizontal plane, thereby providing convenience for the transformer to be lowered to achieve pin correction, ensuring that the transformer can contact the top surface of the correction plate, and ensuring the quality of the transformer pin correction.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4 , a pin correction device for transformer production, comprising a correction plate 1, such as Figure 1 As shown, four supporting columns are arranged at the bottom of the correction plate 1 .

[0024] The correction plate 1 is provided with two rows of correction holes 102 , and each row of correction holes 102 has three correction holes 102 .

[0025] like Figure 1 As shown, a pair of vertical plates 6 are arranged on the top of the correction plate 1, and a positioning member 7 is slidably fitted on the vertical plate 6. The vertical plate 6 is in an inverted "L" shape. A cylinder is arranged on the top of the vertical plate 6, and the piston rod of the cylinder passes through the vertical plate 6 and is connected to the top of the positioning member 7. Furthermore, the positioning member 7 includes a horizontal plate with a groove, and a pair of second electric push rods are arranged in the groove of the horizontal plate. A clamping block is fitted in the groove of the horizontal plate, and the moving ends of the pair of second electric push rods are fixedly connected to the clamping block. First, the transformer to be corrected is taken between the two clamping blocks, and the second electric push rod in the groove of the horizontal plate is started to work, which will cause the clamping block to move outward, thereby clamping and fixing the transformer, and making the pins of the transformer correspond to the correction holes 102 opened on the upper surface of the correction plate 1.

[0026] After adjustment, the cylinder is started to lower the horizontal plate, so that the clamped transformer moves downward and the transformer pin moves toward the inside of the correction hole 102, thereby achieving the purpose of automatic correction of the transformer pin.

[0027] A rectangular groove 101 is provided on the correction plate 1 , and a pair of first electric push rods 4 are provided on the rectangular groove 101 and the correction plate 1 . A driving rod 5 is fixedly connected to the moving end of each first electric push rod 4 .

[0028] The top surface of the correction plate 1 is staggered with movable grooves 103 connected to the correction hole 102, and a support rod 2 is slidably fitted in the movable groove 103. The end of the support rod 2 located in the correction hole 102 is fixedly connected to an adjustment plate 3, and the adjustment plate 3 is an arc-shaped structure. The end of the adjustment plate 3 away from the support rod 2 is fixedly connected to the driving rod 5.

[0029] The size of the correction hole 102 is adjusted according to the size of the transformer pin. At this time, the first electric push rod 4 is started to work. At this time, the two first electric push rods 4 located on both sides of the same row of correction holes 102 work, but the working directions are opposite, that is, the piston rod of one of the first electric push rods 4 extends, and the piston rod of the other first electric push rod 4 contracts, so that the two driving rods 5 move in opposite directions, so that the two adjustment plates 3 inside the correction hole 102 move relative to each other inside the correction hole 102, thereby achieving the purpose of adjusting the size of the correction hole 102.

[0030] Since all the adjustment plates 3 in the same row are connected to the driving rod 5 and driven by the electric push rod 4 to run synchronously, the number of electric push rods 4 used is significantly reduced, which not only reduces the production cost, but also makes the structure of the device more compact and improves space utilization. At the same time, the electric push rod 4 is arranged outside the correction hole 102, so that when a fault occurs, the maintenance and replacement process of the electric push rod 4 is more convenient, which not only reduces the maintenance time and improves the production efficiency, but also reduces the maintenance cost.

[0031] like Figure 3 and Figure 4 As shown, a slide groove 104 is opened in the movable groove 103, and a rectangular block is arranged at the bottom of the support rod 2. The rectangular block slides in cooperation with the slide groove 104, thereby ensuring the stability of movement during the movement of the support rod 2. Three support rods 2 are fixedly connected to the driving rod 5, and the top surface of each support rod 2 is in the same horizontal plane as the top surface of the correction plate 1. At the same time, the support rod 2 moves in the movable groove 103, so that the support rod 2 and the top surface of the correction plate 1 are in the same horizontal plane, thereby providing convenience for the transformer to be lowered to realize pin correction, ensuring that the transformer can contact with the top surface of the correction plate 1, and ensuring the quality of the transformer pin correction.

[0032] Furthermore, all electrical equipment in the device are connected to external power supplies and switches.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
