Description

Technical Field

[0001] This utility model relates to the field of winding mold technology, and in particular to a motor winding mold. Background Technology

[0002] In the manufacturing of electric motors (including industrial drive motors, automotive permanent magnet motors, micro motors for home appliances, and drive motors for new energy vehicles), the winding coil is the core component for realizing the conversion of "electrical energy to mechanical energy" or "mechanical energy to electrical energy," while the winding mold is the key tooling that determines the accuracy, consistency, and production efficiency of the winding coil. Its core function is to guide the enameled wire (or copper flat wire) to be formed according to the designed number of turns and arrangement (such as single-layer close winding, multi-layer overlapping winding, and random winding) through a preset mold core structure, slot size, and positioning reference. Ultimately, this ensures that after the coil is embedded in the motor stator / rotor, it can meet the requirements of the motor's insulation performance, electromagnetic performance, and assembly accuracy.

[0003] Traditional winding die heights cannot be universally applied to every type of chip, requiring the use of different winding dies for each chip's height. Furthermore, users need skilled personnel for debugging and installation, resulting in a significant waste of manpower, resources, and time, and reducing the device's practicality.

[0009] In a preferred embodiment of the motor winding mold of this utility model, convex sliders are symmetrically arranged on both sides of the fixed column, and limiting grooves that cooperate with the sliders are opened on both sides of the slide groove, and the sliders are slidably connected to the limiting grooves.

[0010] In a preferred embodiment of the motor winding mold of this utility model, the opposite sides of the fixing posts located at both ends of the mounting tube abut against the surfaces of the corresponding first fixing ring and second fixing ring, and the side of the fixing post away from the first fixing ring and second fixing ring is inclined.

[0011] In a preferred embodiment of the motor winding mold of this utility model, the two ends of the mounting tube are symmetrically slidably connected with movable rings, and the inner wall of the movable ring is provided with a movable groove.

[0013] (III) Beneficial Effects

[0014] This utility model provides a motor winding mold. It has the following beneficial effects:

[0015] 1. By providing sealing rings between the first and second fixing rings and their corresponding blocking rings, and under the action of the installation mechanism, the sealing performance between the installation tube, the mold sleeve, and the connecting tube can be increased, thus improving the sealing performance. The sealing rings with a larger thickness can ensure a high sealing effect with the cooperation of the installation mechanism. During use, the first fixing ring on the mold sleeve and the second fixing ring on the connecting tube press the corresponding fixing post to make it slide into the corresponding groove. When the first fixing ring, the second fixing ring, and the corresponding fixing post are separated, the fixing post slides out of the groove under the action of the fixing spring, thereby restricting the first fixing ring and the second fixing ring from sliding in opposite directions, thus completing the installation connection between the mold sleeve and the installation tube.

[0016] 2. The cooperation between the slider and the limiting groove increases the stability of the fixed column sliding within the groove and improves the installation and connection effect of the mold sleeve and connecting pipe. It also prevents the fixed column from completely sliding out of the groove when not in use, thus avoiding interference with the installation and connection of the mold sleeve and connecting pipe. The inclined structure on one side of the fixed column facilitates direct insertion of the mold sleeve and connecting pipe into the two ends of the installation pipe, completing the installation and connection work. The movable ring, lifting block, rotating rod, and rollers allow for quick disassembly of the installation pipe from the mold sleeve and connecting pipe, further enhancing the device's practicality. Simultaneously, the cooperation of the movable groove, positioning ring, and compression spring prevents the movable ring from shifting during use, thus avoiding separation between the installation pipe, mold sleeve, and connecting pipe.

[0028] 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.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 9 This is the first embodiment of the present invention, which provides a motor winding mold, including a winding template 6. The winding template 6 is arranged in an I-shape. An insert template 7 is arranged inside the winding template 6 through a cross roller guide rail 9. An inner mold 10 is arranged inside the insert template 7. A pressure spring 11 is arranged between the outer surface of the inner mold 10 and the insert template 7. A winding stator 8 is arranged on the outer surface of the insert template 7. A connecting pipe 3 is arranged on the rear side of the winding template 6. An installation pipe 1 is arranged at the other end of the connecting pipe 3. The other end of the installation pipe 1 is inserted into the winding template 6. A mold sleeve 2 is provided, and a first fixing ring 21 is fixedly sleeved on one end of the mold sleeve 2 that extends into the interior of the mounting tube 1. A second fixing ring 31 is fixedly sleeved on one end of the connecting tube 3 that extends into the interior of the mounting tube 1. Barrier rings 101 are symmetrically arranged at both ends of the interior of the mounting tube 1. A sealing ring 102 is provided between the first fixing ring 21, the second fixing ring 31 and the corresponding barrier ring 11. The distance between the first fixing ring 21, the second fixing ring 31 and the corresponding barrier ring 101 is less than the thickness of the sealing ring 102. An installation mechanism 4 is provided at the end of the mounting tube 1.

[0031] Specifically, the installation mechanism 4 includes an installation ring 41 fixedly connected to the end of the installation tube 1. Several grooves 44 are evenly distributed around the inner wall of the installation ring 41. A fixed post 42 is slidably connected inside the groove 44. A sliding rod 43 is provided on the fixed post 42. One end of each sliding rod 43 extends to the outside of the installation ring 41 and is fixedly connected to the rotating rod 45. The sliding rod 43 is slidably connected to the installation ring 41. A fixed spring 46 is sleeved on one end of the sliding rod 43 inside the groove 44. One end of the fixed spring 46 is fixedly connected to the fixed post 42, and the other end of the fixed spring 46 is fixedly connected to the inner wall of the groove 44. A convex slider 47 is symmetrically arranged on both sides of the fixed post 42. Limiting grooves 48 that cooperate with the slider 47 are opened on both sides of the groove 44, and the slider 47 is slidably connected to the limiting groove 48.

[0032] Furthermore, by providing sealing rings 102 between the first fixing ring 21 and the second fixing ring 31 and the corresponding blocking ring 101, and under the action of the installation mechanism 4, the sealing performance between the installation tube 1, the mold sleeve 2 and the connecting tube 3 can be increased, thus improving the sealing performance. The sealing rings 102 with a larger thickness can ensure a high sealing effect with the cooperation of the installation mechanism 4. During use, the first fixing ring 21 on the mold sleeve 2 and the second fixing ring 31 on the connecting tube 3 squeeze the corresponding fixing post 42 to make it slide into the corresponding sliding groove 44. When the first fixing ring 21, the second fixing ring 31 and the corresponding fixing post 42 are separated, the fixing post 42 slides out from the sliding groove 44 under the action of the fixing spring 46, thereby restricting the first fixing ring 21 and the second fixing ring 31 from sliding in opposite directions, thus completing the installation connection between the mold sleeve 2 and the installation tube 1.

[0033] Example 2

[0034] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] The two ends of the mounting tube 1 are symmetrically slidably connected with movable rings 5, and the inner wall of the movable ring 5 is provided with a movable groove 51. The mounting tube 1 is symmetrically fitted with positioning rings 103 that are slidably connected with the corresponding movable grooves 51. Several compression springs 104 are evenly arranged on the circumference of the two positioning rings 103 on the side away from each other, and the other end of each compression spring 104 is fixedly connected to the side wall of the corresponding movable groove 51. Several lifting blocks 52 located between the two slide rods 43 are fixedly connected to the ends of the two movable rings 5 ​​that are away from each other.

[0036] Specifically, a roller 49 is rotatably sleeved on the rotating rod 45, the lifting block 52 has an L-shaped structure, and the top of the lifting block 52 is slidably connected to the corresponding roller 49. The outer surface of the moving ring 5 is provided with an anti-slip ring 53. The opposite sides of the fixing posts 42 located at both ends of the mounting tube 1 abut against the surfaces of the corresponding first fixing ring 21 and second fixing ring 31. The side of the fixing post 42 away from the first fixing ring 21 and second fixing ring 31 is inclined.

[0037] Furthermore, the cooperation between the slider 47 and the limiting groove 48 increases the stability of the fixed column 42 sliding in the slide groove 44 and the installation connection effect of the mold sleeve 2 and the connecting pipe 3. At the same time, it can prevent the fixed column 42 from completely sliding out of the slide groove 44 when the device is not in use, thus affecting the installation connection of the mold sleeve 2 and the connecting pipe 3. The inclined structure on one side of the fixed column 42 makes it easy for the mold sleeve 2 and the connecting pipe 3 to be directly inserted into the inside of both ends of the installation pipe 1 and complete the installation connection. The moving ring 5, lifting block 52, rotating rod 45 and roller 49 can quickly complete the disassembly of the installation pipe 1, the mold sleeve 2 and the connecting pipe 3, further increasing the practicality of the device. At the same time, the cooperation of the moving groove 51, the positioning ring 103 and the compression spring 104 can prevent the moving ring from moving during the use of the device, thus preventing the separation of the installation pipe 1, the mold sleeve 2 and the connecting pipe 3.

[0038] Working principle: During use, the main body of the mold adopts a high-precision linear slide rail as the guide base. The two side insert templates 7 are connected to the cross roller guide rail 9 through sliders to form an adjustable structure that can slide freely along the vertical stator height direction. When there is an error in the stator chip height, the insert template 7 can automatically rise and fall synchronously with the actual stator height. Before winding, the mold fits against the outer circle of the winding stator 8 through the positioning reference. The two side insert templates 7 contact the end face of the winding stator 8 under the pre-tightening force of the pressure spring 11, automatically compensating for the height error. During the winding process, the rigid guidance of the cross roller guide rail 9 ensures that the insert template 7 only moves in the vertical direction, avoiding the offset of the wire laying position due to height adjustment.

[0039] One end of the mold sleeve 2 and one end of the connecting pipe 3 are respectively inserted into the two ends of the installation pipe 1. During the insertion process, the first fixing ring 21 on the mold sleeve 2 and the second fixing ring 31 on the connecting pipe 3 press the corresponding fixing post 42 to slide into the corresponding sliding groove 44. When the first fixing ring 21, the second fixing ring 31 and the corresponding fixing post 42 are separated, the fixing post 42 slides out from the sliding groove 44 under the action of the fixing spring 46, thereby restricting the first fixing ring 21 and the second fixing ring 31 from sliding in opposite directions, thus completing the installation connection between the mold sleeve 2 and the connecting pipe 3, thereby making the installation more efficient and convenient. At the same time, during the insertion process of the mold sleeve 2 and the connecting pipe 3, the first fixing ring 21 and the second fixing ring 31 will effectively compress the sealing ring 102 with a larger thickness, thereby increasing the sealing performance between the installation pipe 1, the mold sleeve 2 and the connecting pipe 3, making the device have a higher sealing performance.

[0040] When it is necessary to disassemble the mold sleeve 2, the user pushes the moving rings 5 ​​at both ends of the mounting tube 1 toward the middle through the anti-slip ring 53, which drives the lifting block 52 on the moving ring 5 to move. The surface of the lifting block 52 slides with the roller 49. As the lifting block 52 moves continuously, it drives the rotating rod 45 to move upward. The sliding rod 43 moves upward with the rotating rod 45. The sliding rod 43 drives the fixed column 42 to slide in the sliding groove 44. With the cooperation of the slider 47 and the limiting groove 48, the fixed column 42 is more stable when sliding in the sliding groove 44. When the fixed column 42 separates from the first fixed ring 21 and the second fixed ring 31, the mold sleeve 2 is pulled out of the mounting tube 1. At this time, the fixed column 42 is reset in the sliding groove 44 by the elasticity of the fixed spring 46. The moving ring 5 is reset in the mounting tube 1 by the compression spring 104.
