Description

Technical Field

[0001] The utility model relates to the technical field of transformer core production equipment, in particular to a transformer core lamination mold with a measuring device. Background Art

[0002] The iron core is the main magnetic circuit part in a transformer. It is usually laminated by hot-rolled or cold-rolled silicon steel sheets with a relatively high silicon content and an insulating paint coated on the surface. The iron core composed of multiple laminated silicon steel sheets and the coil wound around it together form a complete electromagnetic induction system. The silicon steel sheets are laminated in a staggered manner, so that the joints between adjacent layers of silicon steel sheets are staggered, to reduce the air gap at the joints and the magnetic resistance of the magnetic circuit, and improve the power factor of the iron core during the operation of the transformer. Therefore, when laminating the silicon steel sheets, manual lamination is used, which can not only ensure the staggered lamination of the silicon steel sheets, but also ensure that the formed iron core column meets the later assembly standards.

[0003] To ensure the quality of the iron core after the silicon steel sheets are laminated, it is necessary to ensure that the lamination height of each level of silicon steel sheets is basically consistent with the design value. Therefore, after each level is laminated, it is necessary to separately measure the lamination height of this level of silicon steel sheets to determine whether it meets the process requirements.

[0004] The patent with the authorization announcement number CN219180349U discloses a transformer core silicon steel sheet lamination mold, which includes a base and a lamination module. The lamination module is connected to the base, and a V-shaped groove is provided on the lamination module; it also includes a height measuring component, and the height measuring component includes a bracket and a number of limit rulers. The bracket is arranged on the base, and the limit rulers are all horizontally rotatably connected to the bracket.

[0005] In the above patent, during lamination, the worker can first rotate all the limit rulers towards the outside of the base, so as to facilitate putting the silicon steel sheets into the mold. When the visual lamination height reaches the requirement, directly rotate the limit rulers above the silicon steel sheets, and then the lamination height can be checked whether it meets the requirement of the current level, making the height measurement operation convenient and fast, and improving the efficiency of manual lamination. According to its specification, the limit rulers are horizontally rotatably connected to the bracket, and the height between the bottoms of a number of limit rulers and the base meets the requirement of the level height. From this, it can be known that the limit rulers cannot be flexibly adjusted in height according to actual needs, and only the laminated silicon steel sheets with a specific height can be measured by a number of limit rulers with a specific height, which has limitations. Therefore, its versatility is relatively low; moreover, a number of limit rulers are likely to cause confusion among the staff.

[0006] Therefore, it is necessary to develop a transformer core lamination mold with a measuring device for the above-mentioned defects. Summary of the Utility Model

[0037] The base 1 and the stacking module 12 involved in the present utility model belong to the prior art and will not be elaborated here.

[0038] In a specific embodiment of the present utility model, as Figures 1 to 8 shown, it includes a base 1 and a stacking module 12. A through groove 101 is provided on the base 1, and the stacking module 12 is fixed on one side frame of the base 1. It further includes:

[0039] A slide rail 2, which is vertically fixed on the other side frame of the base 1;

[0040] A slider 3, which is slidably clamped with the slide rail 2;

[0041] A measuring rod 4, which is movably connected to the end of the slider 3. A jack 303 is horizontally provided at the central position of the end of the slider 3, and the measuring rod 4 can be horizontally inserted into the jack 303;

[0042] A scale 5, which is arranged on one side of the surface of the slide rail 2. The top surface of the slider 3 corresponds to the scale line of the scale 5. When the measuring rod 4 is inserted into the jack 303, it indirectly shows the height between the bottom surface of the measuring rod 4 and the top surface of the base 1. The scale line corresponding to the top surface of the slider 3 on the scale 5 is the height between the bottom surface of the measuring rod 4 and the top surface of the base 1.

[0043] A driving device, which is connected to the slide rail 2 and drives the slider 3 to slide in the vertical direction for guiding.

[0044] Specifically, the silicon steel sheets to be stacked are erected on two opposite side frames of the base 1, and one end of the silicon steel sheet is aligned with the V-shaped groove on the stacking module 12. Initially, the slider 3 is located at the top end of the slide rail 2. When the staff believes that the stacking height of the silicon steel sheets needs to be measured, one end of the measuring rod 4 is inserted into the jack 303, and the driving device drives the slider 3 to move downward, then the measuring rod 4 moves downward synchronously. When the bottom surface of the measuring rod 4 contacts the top silicon steel sheet, the stacking height of the silicon steel sheets can be obtained through the corresponding scale line on the top surface of the slider 3 and the ruler 5, so as to judge whether the stacking height of the silicon steel sheets meets the requirements. Or, first adjust the slider 3 to the stacking height of the silicon steel sheets required by the process, and then start stacking the silicon steel sheets. When the staff believes that the stacking height of the silicon steel sheets needs to be measured, try to insert one end of the measuring rod 4 into the jack 303. If the stacking height of the silicon steel sheets exceeds the process requirements, it will interfere with the measuring rod 4 and the measuring rod 4 cannot be inserted into the jack 303. If the measuring rod 4 can be inserted into the jack 303 and the bottom surface of the measuring rod 4 contacts the top silicon steel sheet, the stacking height of the silicon steel sheets meets the requirements. If the measuring rod 4 can be inserted into the jack 303 and there is a gap between the bottom surface of the measuring rod 4 and the top silicon steel sheet, the stacking height of the silicon steel sheets does not meet the requirements. In summary, through the present utility model, the staff can measure the height of more stacked silicon steel sheets, not limited to measuring the stacked silicon steel sheets with a specific height, with flexible use and strong versatility.

[0045] Side plates 301 are provided on both sides of the end of the slider 3. A round rod 6 is horizontally erected between the two side plates 301. The round rod 6 is arranged along the width direction of the slider 3. A strip-shaped through hole 401 is provided in the middle of the measuring rod 4. The strip-shaped through hole 401 is opened along the length direction of the measuring rod 4 to both ends of the measuring rod 4. The circumferential surface of the round rod 6 is slidably matched with the inner wall of the strip-shaped through hole 401. Specifically, the round rod 6 and the side plate 301 can be welded or threadedly connected. When the measuring rod 4 is not used to measure the stacking height of the silicon steel sheets, the measuring rod 4 is adjusted to Figure 1 the state shown in the figure, which is convenient for the staff to stack the silicon steel sheets. When it is necessary to use the measuring rod 4 to measure the stacking height of the silicon steel sheets, lift the measuring rod 4 upward. When the measuring rod 4 is limited by the round rod 6, rotate the measuring rod 4 to one side. When the measuring rod 4 is in a horizontal state, insert one end of the measuring rod 4 into the jack 303.

[0046] A magnet 7 is fixedly bonded in the jack 303. The magnet 7 magnetically attracts the end of the measuring rod 4 inserted into the jack 303. Specifically, it is to prevent the measuring rod 4 from sliding out of the jack 303 during the measurement process. The measuring rod 4 is made of iron material, and the magnet 7 is made of a strong magnetic material.

[0047] One side of the sliding rail 2 is vertically penetrated with a dovetail groove 201. One end of the slider 3 is provided with a dovetail projection 302 that matches the dovetail groove 201. The dovetail projection 302 is slidably clamped with the dovetail groove 201. The driving device is in threaded transmission connection with the dovetail projection 302 and drives the dovetail projection 302 to slide in the vertical direction. Specifically, since the dovetail groove 201 limits the dovetail projection 302, the slider 3 is limited, and the slider 3 can only slide in the vertical direction for guiding.

[0048] The driving device includes a driving rod 8, an end cover 9 and a handle 10. The end cover 9 is fixed to the top end of the sliding rail 2 by bolts. The driving rod 8 vertically penetrates the end cover 9 and extends into the dovetail groove 201. The driving rod 8 is rotatably connected to the end cover 9. The bottom end surface of the driving rod 8 is in rotational contact with the top surface of the base 1. A threaded section is provided on the driving rod 8, and a threaded through hole is provided on the dovetail projection 302. The threaded section is in threaded transmission connection with the threaded through hole of the dovetail projection 302. A limiting projection 801 is provided on the driving rod 8, and the top surface of the limiting projection 801 is in contact with the bottom surface of the end cover 9. The handle 10 is horizontally fixed to the top end of the driving rod 8. Specifically, when the handle 10 is rotated, the driving rod 8 rotates, and the threaded section of the driving rod 8 drives the dovetail projection 302 to move up and down through the thread, and then the slider 3 drives the measuring rod 4 to move up and down.

[0049] It further includes a support rod 11. The support rod 11 is horizontally slidably mounted in the through groove 101, and the top surface of the support rod 11 is flush with the top surface of the base 1.

[0050] Sliding grooves 102 are horizontally provided on the inner sides of two opposite frames of the base 1. Square tenons 1101 are provided at both ends of the support rod 11. The square tenons 1101 are slidably clamped with the sliding grooves 102. Openings 103 for the square tenons 1101 to enter the sliding grooves 102 are provided on two opposite frames of the base 1. Specifically, the support rod 11 is used to support the middle part of the silicon steel sheet to prevent the two ends from warping and the middle part from sagging when the silicon steel sheets are stacked. After stacking is completed, the support rod 11 is slid to one side, and at this time, the staff can use a handling device to move the silicon steel sheet away.

[0051] The working principle of a laminated mold for a transformer core with a measuring device in the present utility model: The silicon steel sheets to be laminated are placed on two opposite frames of the base 1, and one end of the silicon steel sheet is aligned with the V-shaped groove on the lamination module 12. Initially, the slider 3 is located at the top end of the slide rail 2. When the staff believes that the lamination height of the silicon steel sheet needs to be measured, one end of the measuring rod 4 is inserted into the jack 303, and the driving device drives the slider 3 to move downward, then the measuring rod 4 moves downward synchronously. When the bottom surface of the measuring rod 4 contacts the top-layer silicon steel sheet, the lamination height of the silicon steel sheet is obtained through the corresponding scale line on the top surface of the slider 3 and the ruler 5, so as to judge whether the lamination height of the silicon steel sheet meets the requirements. Or, first adjust the slider 3 to the lamination height of the silicon steel sheet required by the process, and then start laminating the silicon steel sheet. When the staff believes that the lamination height of the silicon steel sheet needs to be measured, try to insert one end of the measuring rod 4 into the jack 303. If the lamination height of the silicon steel sheet exceeds the process requirements, it will interfere with the measuring rod 4 and the measuring rod 4 cannot be inserted into the jack 303. If the measuring rod 4 can be inserted into the jack 303 and the bottom surface of the measuring rod 4 contacts the top-layer silicon steel sheet, the lamination height of the silicon steel sheet meets the requirements. If the measuring rod 4 can be inserted into the jack 303 and there is a gap between the bottom surface of the measuring rod 4 and the top-layer silicon steel sheet, the lamination height of the silicon steel sheet does not meet the requirements. In summary, through the present utility model, the staff can measure the height of more laminated silicon steel sheets, not limited to measuring the laminated silicon steel sheets with a specific height, and it is flexible to use and has strong versatility.
