Description
Technical Field
[0001] The utility model relates to the technical field of coil bending processing, in particular to a coil right-angle bending structure. Background Art
[0002] Coil bending is an essential component in fields such as electronic equipment and industrial automation. In a motor's armature, the coils, wound and connected according to a specific pattern, are called rotor windings and are a key component in achieving electromechanical energy conversion. The portion of the coil embedded in the slot is called the active portion, while the portion extending outside the slot is called the connecting end (or simply, the end). The bending of these ends is crucial to the proper operation and performance of the motor.
[0003] For example, the Chinese patent application CN218395698U, "A Coil Bending and Forming Device," includes a base, a table fixedly connected to the top of the base, a through slot on one side of the top of the table, a turntable within the slot, a movable slot on the top of the front surface of the turntable, a limit rod fixedly connected to the bottom of the movable slot, and a movable rod in the middle of the movable slot. This coil bending and forming device, through the coordinated use of a screw, movable slot, movable rod, and guide plate, allows for adjustable dimensions, making it convenient for users to process coils of various diameters.
[0004] In actual use, the above-mentioned existing technology does not meet existing needs because the coil has a flat structure and is prone to twisting during the bending process, which can easily cause the bending effect to fail to meet processing requirements and easily damage the external insulation layer of the coil. In this regard, we propose a coil right-angle bending structure. Utility Model Content
[0005] The purpose of the present invention is to provide a coil right-angle bending structure to solve the problem in the above background art that the coil is easily twisted during the bending process, thereby affecting the bending effect.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a coil right-angle bending structure, comprising a first disc and a second disc, and the second disc is located above the first disc, a fixing cap is provided at the middle position of the bottom of the first disc, and the fixing cap is welded and fixed to the first disc, the upper end of the fixing cap is integrally cast with a support column, and the support column passes through the first disc and extends to the interior of the second disc, and the support column rotates with the second disc, the upper end of the support column is provided with a stud, and the stud passes through and extends to the outside of the second disc, and an adjustment cap is provided at one end of the stud located outside the second disc, and the inner screw hole of the adjustment cap is adapted to the stud.
[0007] Preferably, a spring is installed between the bottom of the adjusting cap and the upper end surface of the second disc.
[0008] Preferably, a bending portion is provided on the opposite side of the first disc and the second disc, and the bending portion is cast integrally with the first disc and the second disc respectively. The bending portion is located on the same plane as the support column and a bending column is provided. The bending column and the support column constitute the bending structure of the coil.
[0009] Preferably, an adjustment groove is provided inside the bending part, and a limiting slide groove is provided at one end of the adjustment groove close to the bending column. A nut is installed inside the limiting slide groove, and two sides of the nut are limited by the limiting slide groove, and the nut is slidably connected to the limiting slide groove. A nut is provided on the other side of the adjustment groove, and one end of the nut is fixedly provided with a threaded end, and the threaded end is slidably connected to the adjustment groove, and the threaded end is adapted to the nut, and one end of the threaded end is welded and fixed to the bending column.
[0010] Preferably, a handle is provided on one side of the bending portion, and the handle and the bending portion are integrally cast.
[0011] Preferably, the bending column and the supporting column have the same diameter.
[0012] Preferably, the length of the bending column is greater than the length of the maximum gap between the first disc and the second disc.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] 1. The utility model is provided with a coil positioning structure. The coil passes between the first disc and the second disc, and after the bent end contacts the support column, the user holds the handle and rotates the adjusting cap. The inner screw hole thereof generates friction with the stud of the fixing cap, converting the rotary motion into linear motion, causing the adjusting cap to move downward. The spring applies a downward force to the second disc, so that the lower end surface of the second disc is fitted with the upper end surface of the coil, thereby achieving the fixation of the upper and lower end surfaces of the coil between the first disc and the second disc. At the same time, in order to avoid excessive squeezing of the coil by vertical pressure, the spring is set to undergo elastic deformation when the pressure increases, thereby forming a buffer for the pressure and preventing direct transmission of pressure from damaging the coil. This structure can not only prevent the bending effect of the coil from being affected by distortion during positioning, but also protect the coil during the clamping process, thereby effectively improving practicality.
[0015] 2. The utility model adopts an adjustable structure for the bending column. Before installation, it is only necessary to clamp the nut inside the limiting slide groove, and move the nut in the limiting slide groove according to the subsequent bending requirements. After reaching the specified position, the nut is inserted into the adjustment groove from the other side of the bending part. The bending column preferably passes through the adjusting groove and the nut. When the threaded end contacts the nut, the user rotates the nut. Under the friction of the threads of the two, the limiting slide groove limits the nut, so that the nut moves toward the bending part until it fits tightly with it, thereby fixing the bending column at this position. This structure can not only meet the different bending requirements of the coil, but also the adjustment method is convenient and easy to operate, and the firmness is high.

[0021] 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 the embodiments.
[0022] See also Figure 1-4 The utility model provides an embodiment: a coil right-angle bending structure, comprising a first disc 1 and a second disc 2, and the second disc 2 is located above the first disc 1, and a fixing cap 3 is provided at the middle position of the bottom of the first disc 1, and the fixing cap 3 is welded and fixed to the first disc 1, and a support column 11 is integrally cast at the upper end of the fixing cap 3, and the support column 11 passes through the first disc 1 and extends to the interior of the second disc 2, and the support column 11 rotates with the second disc 2, and a stud 4 is provided at the upper end of the support column 11, and the stud 4 passes through and extends to the outside of the second disc 2, and an adjusting cap 5 is provided at one end of the stud 4 located outside the second disc 2, and the inner screw hole of the adjusting cap 5 is adapted to the stud 4.
[0023] During use, the coil 15 passes between the first disk 1 and the second disk 2, and after the bent end contacts the support column 11, the user holds the handle 16 and rotates the adjusting cap 5. The inner screw hole thereof generates friction with the stud 4 of the fixing cap 3, converting the rotational motion into linear motion, causing the adjusting cap 5 to move downward, and applying a downward force to the second disk 2 through the spring 6, so that the lower end surface of the second disk 2 is fitted with the upper end surface of the coil 15, thereby achieving the upper and lower end surfaces of the coil 15 being fixed between the first disk 1 and the second disk 2.
[0024] See also Figure 2 and Figure 3 A spring 6 is installed between the bottom of the adjusting cap 5 and the upper end surface of the second disc 2. In order to prevent the vertical pressure from causing excessive extrusion of the coil 15, the setting of the spring 6 can undergo elastic deformation when the pressure increases, thereby forming a buffer for the pressure and preventing the direct transmission of pressure from damaging the coil 15. This structure can not only prevent the coil 15 from being twisted during positioning and affecting the bending effect, but also can protect the coil 15 during the clamping process.
[0025] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A bending portion 7 is provided on the opposite side of the first disc 1 and the second disc 2, and the bending portion 7 is cast integrally with the first disc 1 and the second disc 2 respectively. A bending column 10 is provided on the same plane as the support column 11 of the bending portion 7. The bending column 10 and the support column 11 constitute the bending structure of the coil. The bending column 10 and the support column 11 have the same diameter. The length of the bending column 10 is greater than the length of the maximum gap between the first disc 1 and the second disc 2. A handle 16 is provided on one side of the bending portion 7, and the handle 16 is cast integrally with the bending portion 7, which solves the problem that the coil is easily twisted during the bending process, thereby affecting the bending effect.
[0026] See also Figure 2 and Figure 3 The interior of the bending part 7 is provided with an adjusting groove 9, and a limiting slide groove 14 is provided at one end of the adjusting groove 9 close to the bending column 10. A nut 13 is installed inside the limiting slide groove 14, and the two sides of the nut 13 are limited by the limiting slide groove 14, and the nut 13 is slidably connected to the limiting slide groove 14. A nut 8 is provided on the other side of the adjusting groove 9, and one end of the nut 8 is fixedly provided with a threaded end 12, which is slidably connected to the adjusting groove 9, and the threaded end 12 is adapted to the nut 13, and one end of the threaded end 12 is welded and fixed to the bending column 10. This structure can not only meet the different bending requirements of the coil 15, but also the adjustment method is convenient and easy to operate, and the firmness is high.
[0027] Working principle: Before installation, the nut 13 needs to be clamped in the inside of the limiting slide 14, and the nut 13 is moved in the limiting slide 14 according to the subsequent bending requirements. After reaching the specified position, the nut 8 is inserted into the adjusting groove 9 from the other side of the bending portion 7. The bending column 10 preferably passes through the adjusting groove 9 and the nut 13. When the threaded end 12 contacts the nut 13, the user rotates the nut 8. Under the friction of the threads of the two, the limiting slide 14 limits the nut 13, so that the nut 8 moves toward the bending portion 7 until it is tightly fitted with it, forming a fixation of the bending column 10 at this position. Figure 4 , then the user passes the coil 15 from under the bending column 10 of the second disk 2 into the gap between the first disk 1 and the second disk 2, and after passing through the top of the support column 11, the user adjusts the direction of the coil so that it moves out from under the bending column 10 of the first disk 1, and by rotating the adjusting cap 5, the first disk 1 and the second disk 2 clamp the upper and lower end surfaces of the coil. Finally, the user closes the handles 16 to cause relative rotation between the first disk 1 and the second disk 2, and under the joint action of the bending column 10 and the support column 11, the coil 15 is bent at a right angle.
[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
