Description

Technical Field

[0001] This utility model relates to the field of motor coil manufacturing technology, specifically to an adjustable motor coil winding clamp. Background Technology

[0002] The motor coil is the core component of the motor that realizes the conversion of electrical energy to mechanical energy (or mechanical energy to electrical energy). Essentially, it is a conductive winding made of insulated wires wound according to specific rules. Its function is to generate a magnetic field through current, or to generate an induced electromotive force by cutting magnetic field lines in a magnetic field, thereby driving the motor to run or generating electricity. In the production process of motor coils, it is usually necessary to use it in conjunction with a winding fixture.

[0003] Currently, most winding fixtures can only produce motor coils of fixed sizes according to parameters such as core length and pitch. This means that manufacturers need to make multiple sets of winding fixtures when producing different models of motor coils. The parameters of the winding fixtures need to be adjusted in real time during the manufacturing process, which not only wastes time but also fails to meet the material requirements. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable motor coil winding clamp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable motor coil winding clamp, comprising: a rotating shaft for driving the clamp to rotate; a plurality of partition plates sleeved on the rotating shaft; a winding mold slidably disposed on the partition plates, the winding mold being symmetrically disposed on the partition plates and capable of moving along the length direction of the partition plates; and a base plate fixedly disposed at the bottom end of the rotating shaft, the surface of the winding mold being in contact with the surface of the adjacent partition plate or the base plate.

[0006] Preferably, it further includes: a guide groove formed on the partition plate, the guide groove being symmetrically arranged on the partition plate; an adjusting screw rotatably disposed inside the partition plate, the adjusting screw being located inside the guide groove; and a slider fixedly disposed on the winding die, the outer surface of the slider being slidably disposed with respect to the inside of the guide groove, and the outer surface of the adjusting screw being threaded with respect to the inside of the slider.

[0007] Preferably, it further includes: a docking post, fixedly disposed at one end of the adjusting screw, the docking post having a polygonal structure; an adjusting sleeve, slidably disposed on the surface of the docking post, the surface of the docking post cooperating with the interior of the adjusting sleeve; and a limiting sleeve, fixedly disposed on one side of the partition plate, one end of the adjusting sleeve cooperating with the interior of the limiting sleeve.

[0008] Preferably, it further includes: a limiting groove formed on the adjusting sleeve; a limiting bolt threaded on the outer surface of the limiting sleeve, wherein when one end of the limiting bolt is positioned inside the limiting groove, the position of the adjusting sleeve is fixed.

[0009] Preferably, it further includes: a limiting groove formed on the rotating shaft; a limiting block fixedly disposed inside the partition plate, the outer surface of the limiting block being slidably disposed with the inner surface of the limiting groove, and the adjusting screw passing through the interior of the limiting block; and a pressing plate threaded onto the top of the rotating shaft.

[0010] Preferably, it further includes: a positioning groove formed on the partition plate; and a limiting block fixedly disposed on the winding mold, wherein the outer surface of the limiting block is slidably disposed with respect to the interior of the positioning groove.

[0011] Preferably, it further includes: a counterweight block, fixedly disposed on the side of the partition plate away from the docking column; and a limiting plate, fixedly disposed at one end of the docking column.

[0012] This utility model provides an adjustable motor coil winding clamp, which has the following advantages:

[0013] (1) This utility model uses the rotating adjusting screw to drive the two winding molds located on the same partition plate to adjust their positions, so that the clamp can wind coils of different diameters. It does not require the production of a winding clamp with a straight edge for the iron core length. A set of winding clamps can be used to wind coils of different sizes, which improves its practicality.

[0014] (2) By setting up the docking post, adjusting sleeve and limiting sleeve, the position of the adjusting screw is restricted when the adjusting sleeve slides along the surface of the docking post to the inside of the limiting sleeve, so that the adjusting screw will not rotate due to the tension of the winding during the winding process, thus improving the stability of the winding mold after position adjustment.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: Referring to 1-5, in this embodiment, an adjustable motor coil winding clamp includes: a rotating shaft 1 for driving the clamp to rotate, the rotating shaft 1 being made of steel material, and having a threaded groove on its surface near the top; several partition plates 2 being sleeved on the rotating shaft 1, which can be made of wood or hollow aluminum alloy plates; a winding mold 5 being slidably disposed on the partition plates 2, the winding mold 5 being symmetrically disposed on the partition plates 2 and being able to move along the length direction of the partition plates 2; and a base plate 17 being fixedly disposed at the bottom end of the rotating shaft 1, the surface of the winding mold 5 being in contact with the surface of the adjacent partition plate 2 or the base plate 17.

[0023] The winding mold 5 can be moved along the axis of the partition plate 2, and the distance between the winding molds 5 can be adjusted to realize winding operations of different sizes. By setting the partition plate 2, multiple winding molds 5 can be isolated, which facilitates the simultaneous winding of multiple sets of coils and can simultaneously wind coils of different sizes.

[0024] It also includes: a guide groove 3, which is formed on the partition plate 2 and can be integrally formed with the partition plate 2. The guide groove 3 is symmetrically arranged on the partition plate 2; an adjusting screw 4, which is rotatably set inside the partition plate 2 and is located inside the guide groove 3; and a slider 8, which is fixedly set on the winding mold 5 and can be connected and fixed to the winding mold 5 by welding or threaded connection. The outer surface of the slider 8 is slidably set inside the guide groove 3, and the outer surface of the adjusting screw 4 is threaded inside the slider 8.

[0025] The guide groove 3 is designed to position the winding mold 5 in conjunction with the slider 8. The slider 8, in conjunction with the adjusting screw 4, can simultaneously move the two winding molds 5, achieving synchronous adjustment.

[0026] It also includes: a docking post 9, which is fixedly installed at one end of the adjusting screw 4 and connected and fixed by welding. The docking post 9 has a polygonal structure, specifically a pentagon, a hexagon, etc., depending on the adjustment accuracy. The higher the accuracy, the more sides there are; an adjusting sleeve 10, which is slidably installed on the surface of the docking post 9 and the surface of the docking post 9 cooperates with the inside of the adjusting sleeve 10; and a limiting sleeve 11, which is fixedly installed on one side of the partition plate 2 and one end of the adjusting sleeve 10 cooperates with the inside of the limiting sleeve 11.

[0027] The adjusting sleeve 10 can both rotate the adjusting screw 4 by cooperating with the docking column 9 and fix the adjusting screw 4 by cooperating with the limiting sleeve 11.

[0028] It also includes: a limiting groove 12, which is formed on the adjusting sleeve 10 and can be integrally formed with the adjusting sleeve 10; a limiting bolt 13, which is threaded on the outer surface of the limiting sleeve 11. When one end of the limiting bolt 13 is set to be inside the limiting groove 12, the position of the adjusting sleeve 10 is fixed.

[0029] By setting the limiting groove 12 and the limiting bolt 13, the position of the adjusting sleeve 10 can be limited so that it will not fall out of the limiting sleeve 11 when it rotates with the partition plate 2.

[0030] It also includes: a limiting groove 19, which is opened on the rotating shaft 1; a limiting block 18, which is fixedly set inside the partition plate 2 and can be connected by welding or other means. The limiting block 18 is hollow and its outer surface slides on the inner surface of the limiting groove 19. The adjusting screw 4 passes through the inside of the limiting block 18; and a pressing plate 16, which is threaded on the top of the rotating shaft 1.

[0031] By setting the limiting block 18, the partition plate 2 can be positioned by cooperating with the limiting groove 19, so that it can rotate together with the rotating shaft 1.

[0032] It also includes: a positioning groove 6, which is formed on the partition plate 2; and a limiting block 7, which is fixedly set on the winding mold 5. The outer surface of the limiting block 7 is slidably set with the inside of the positioning groove 6, which can position the winding mold 5 and prevent it from being skewed or other situations.

[0033] It also includes: a counterweight 15, which is fixedly installed on the side of the partition plate 2 away from the docking column 9; and a limiting plate 14, which is fixedly installed at one end of the docking column 9. By setting the counterweight 15, the balance of the partition plate 2 can be maintained when it rotates.

[0034] This utility model provides an adjustable motor coil winding clamp, the specific working principle of which is as follows:

[0035] When winding the motor coil, the operator first adjusts the position of the winding mold 5 according to the required winding size. The operator first pulls the adjusting sleeve 10 out of the limiting sleeve 11, then rotates the adjusting sleeve 10 to drive the adjusting screw 4 to rotate. During the rotation of the adjusting screw 4, the winding mold 5 is driven to move and reach the designated position. Then, the adjusting sleeve 10 is inserted into the limiting sleeve 11 to limit the adjusting screw 4. Finally, the operator turns the limiting bolt 13 so that one end enters the limiting groove 12 to fix the adjusting sleeve 10 for the second time. After the fixation is completed, the operator puts the partition plate 2 on the rotating shaft 1 in sequence, and then rotates the pressing plate 16 to press the partition plate 2.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
