Description

Technical Field

[0001] This utility model relates to the field of transformer production testing, specifically a transformer production testing device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. During the production of a transformer, it is necessary to test it, including a withstand voltage test.

[0003] Existing transformer production testing devices, such as the transformer production testing equipment proposed in patent application number "CN202221585191.9", include a base, side plate, bearing, screw, fixed clamp, and other structures. The transformer to be tested is placed on the support block, and the throttle is turned to make the screw rotate. When the screw rotates, it can cooperate with the screw hole, driving the movable clamp to move to the left, and then cooperate with the fixed clamp to fix transformers of different sizes. It has a wide range of applications.

[0004] However, existing technology has its drawbacks. It can only fix the two sides of the transformer, and cannot position the front and rear ends of the transformer. This causes the front and rear positions of the transformer to shift, the center of the withstand voltage test to shift, and the test results to be biased. Therefore, a transformer production testing device is proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] A transformer production testing device, such as Figures 1-4 As shown, it includes a base 1, a test mounting bracket 2 for installing a test mechanism is fixedly connected to one side of the base 1, a side clamping mechanism is slidably connected to the upper end of the base 1, the side clamping mechanism is used to squeeze and position the two sides of the transformer, and two sets of positive clamping mechanisms are fixedly connected to the upper end of the base 1, the positive clamping mechanisms are used to squeeze and position the front and rear ends of the transformer, and the two ends of the side clamping mechanism are squeezed and cooperated with the positive clamping mechanism.

[0024] The test equipment for compressing the transformer is installed through the test mounting bracket 2. This test equipment is existing technology. The side clamping mechanism is operated manually or mechanically. The side clamping mechanism compresses both sides of the transformer. At the same time, the operation of the side clamping mechanism drives the front clamping mechanism, so that the front clamping mechanism compresses the transformer from front to back. This ensures that all four sides of the transformer are compressed, making the transformer centered. The center of the transformer is directly below the test equipment, which improves the accuracy of the transformer test results.

[0025] like Figures 1-2 As shown, a sliding groove 3 is provided in the middle of the upper end of the base 1. The side clamping mechanism includes a double-headed screw 4, which is rotatably connected to the sliding groove 3. A handle 5 is fixed to one end of the double-headed screw 4, and the handle 5 is rotatably connected to the base 1. Both ends of the double-headed screw 4 are threadedly connected to a lower pressure plate 6. The threads at both ends of the double-headed screw 4 are in opposite directions, and the lower ends of the two sets of lower pressure plates 6 are slidably connected to the sliding groove 3.

[0026] The groove 3 is recessed into the base 1 to accommodate the double-ended screw 4. The thread lengths and pitches at both ends of the double-ended screw 4 are the same, only the rotation directions of the threads are opposite. The lower ends of the two sets of lower pressure plates 6 are threaded to both ends of the double-ended screw 4, and both sets of lower pressure plates 6 are slidably connected to the base 1. They are symmetrical about the center of the double-ended screw 4. When the handle 5 is turned, the double-ended screw 4 rotates, driving the two sets of lower pressure plates 6 to move in opposite directions. This causes the two sets of lower pressure plates 6 to press against both sides of the transformer, pushing the transformer to move and centering it left and right. The transformer does not exert any gravity on the lower pressure plates 6, and does not increase the resistance to the movement of the lower pressure plates 6.

[0027] like Figures 1-4 As shown, the positive clamping mechanism includes a bearing seat 9, which is fixedly connected to the upper end of the base 1. A vertical plate 10 is fixedly connected to the upper middle part of the bearing seat 9. A positive extrusion mechanism is inserted and installed on the vertical plate 10. Both ends of the bearing seat 9 are slidably connected to a driving mechanism, which is rotatably connected to the positive extrusion mechanism.

[0028] The positive compression mechanism of the two sets of positive clamping mechanisms compresses the front and rear ends of the transformer, driving the transformer to be centered at the front and rear, and the driving mechanism drives the positive compression mechanism to move.

[0029] like Figures 1-3 As shown, the positive compression mechanism includes a column 11, which is inserted and installed on the vertical plate 10. One end of the column 11 is fixedly connected to an upper pressure plate 12, which is located above the lower pressure plate 6. The other end of the column 11 is fixedly connected to a compression spring 13, which is sleeved on the column 11 and has its end fixedly connected to the vertical plate 10.

[0030] The compression spring 13 is always in a compressed state, squeezing one end of the column 11, so that the upper pressure plate 12 is away from the transformer. The drive mechanism drives the upper pressure plate 12 to slide. The upper pressure plate 12 is above the lower pressure plate 6 and will not affect the sliding of the lower pressure plate 6.

[0031] like Figures 1-3 As shown, the driving mechanism includes a slide 14, which is slidably connected to the bearing 9. The lower end of the slide 14 slides on the base 1. A connecting arm 16 is rotatably connected to one side of the slide 14. The end of the connecting arm 16 is rotatably connected to the upper pressure plate 12. Return springs 15 are fixedly connected to both sides of the vertical plate 10. Both sets of return springs 15 are sleeved on the bearing 9. The ends of the two sets of return springs 15 are fixedly connected to the two sets of slides 14 respectively. The angle between the connecting arm 16 and the spring is an acute angle.

[0032] The slide 14 is pressed by the side clamping mechanism, causing the slide 14 to slide. The connecting arm 16 rotates and supports the upper pressure plate 12, bringing the upper pressure plate 12 closer to the transformer. The angle between the connecting arm 16 and the spring is always an acute angle to avoid the structure getting stuck due to a right angle or higher. When the upper pressure plate 12 is close to the transformer and the slide 14 is close to the vertical plate 10, the return spring 15 is compressed, and the compression spring 13 is compressed more. When the slide 14 is no longer pressed by the side clamping mechanism, the return spring 15 presses the slide 14, the angle between the connecting arm 16 and the spring decreases, and the upper pressure plate 12 moves away from the transformer. At the same time, the compression spring 13 restores its compression, promoting the upper pressure plate 12 to move away from the transformer.

[0033] like Figures 1-4 As shown, both ends of the lower pressure plate 6 are fixedly connected to the drive plate 7, and the drive plate 7 is pressed into one side of the slide block 14.

[0034] The lower pressure plate 6 drives the slide block 14 to slide via the drive plates 7 at both ends.

[0035] The working principle of the transformer production testing device provided by this utility model is as follows:

[0036] The transformer is placed between the side clamping mechanism and the front clamping mechanism. By turning the handle 5, the double-headed screw 4 drives the two sets of lower pressure plates 6 to approach the transformer and push the transformer to center left and right. At the same time, the drive plates 7 at both ends of the lower pressure plates 6 push the slide 14 to slide on the bearing 9, so that the connecting arm 16 rotates and supports the upper pressure plate 12, so that the upper pressure plate 12 approaches the transformer and pushes the front and back of the transformer to center it. Therefore, the side clamping mechanism and the front clamping mechanism operate at the same time, so that the transformer is centered and positioned in four directions: front, back, left, and right. The operation is simple and improves the accuracy of the transformer test results.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
