Description

Technical Field

[0001] This utility model relates to the field of motor winding molds, specifically an adjustable motor winding mold structure. Background Technology

[0002] Wound-rotor motors are just one type of asynchronous motor. Asynchronous motors are classified into wound-rotor and squirrel-cage types according to the rotor winding form. A three-phase asynchronous motor consists of two basic parts: the stator and the rotor. The stator is the stationary part of the motor, used to generate a rotating magnetic field, and mainly consists of components such as the stator core, stator windings, and base.

[0003] In existing technologies, two types of winding machines and winding machines are generally used when producing motor stators. The winding machine requires manual insertion of the coiled wire into the winding post. The motor stator to be wound is then fitted onto the end of the winding post. A drive motor rotates and lowers a pressure rod to the end of the motor stator, limiting its position. Then, a push rod from the winding machine moves the coil and inserts it into the inside of the motor stator, completing the winding operation. However, the rotation and descent distance of the pressure rod is fixed. When winding motor stators of different lengths, winding posts of different lengths need to be replaced to match the motor stator. Based on this, this invention proposes an adjustable motor winding mold structure. Utility Model Content

[0029] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-3 In this embodiment of the utility model, an adjustable motor winding mold structure includes a main shell 1, a winding post 2 fixed on the outer wall of the main shell 1, guide rods 3 fixed on both sides of the winding post 2 on the outer wall of the main shell 1, a rotating pressing rod 4 slidably installed in the inner cavity of the guide rod 3, a movable post 5 slidably installed in the inner cavity of the end of the rotating pressing rod 4, and an adjustment mechanism 6 provided on the movable post 5.

[0031] The adjusting mechanism 6 includes a transmission unit and a limit unit;

[0032] The transmission unit is used to guide the movement of the limit unit;

[0033] The limiting unit is used to limit the connection between the rotating pressure rod 4 and the movable column 5;

[0034] The transmission unit includes a pressing block 601, a spring 602, a push rod 603, a guide block 604, a movable block 605, and a guide groove 606;

[0035] The pressing block 601 is axially slidably installed in the inner cavity of the movable column 5 and extends to the outside of the movable column 5. The pressing block 601 is used to synchronously drive the push rod 603 to move axially.

[0036] The two ends of the spring 602 are respectively engaged inside the movable column 5 and on the outer wall of the pressing block 601. The spring 602 is used to always provide the pressing block 601 with an outward squeezing force.

[0037] Push rod 603 is fixed to the end of pressing block 601, and push rod 603 is used to synchronously push guide block 604 to move axially;

[0038] The guide block 604 is fixed to the end of the push rod 603, and the guide block 604 is used to apply extrusion force to the guide groove 606;

[0039] The movable block 605 is vertically slidably installed in the inner cavity of the movable column 5. The movable block 605 is used to synchronously drive the guide groove 606 to move.

[0040] A guide groove 606 is formed on the inner side of the movable block 605, and the guide groove 606 is used to guide the passage of the guide block 604.

[0041] The limiting unit includes a limiting block 607 and a limiting annular groove 608;

[0042] The limiting block 607 is fixed to the outer wall of the movable block 605 and extends through the movable column 5 to the interior of the rotating pressure rod 4. The limiting block 607 is used to limit the connection between the movable column 5 and the rotating pressure rod 4.

[0043] The limiting ring groove 608 is formed inside the rotating pressing rod 4, and the limiting ring groove 608 is used to provide space for the insertion of the limiting block 607.

[0044] In this embodiment: Through this structure, the coil can be pushed into the inner side of the wire embedding column 2. By sleeving the motor stator on the end of the wire embedding column 2, and starting the driving unit inside the main body housing 1 to drive the rotary pressing rod 4 to rotate and press down, the movable column 5 fixed at the end of the rotary pressing rod 4 approaches and contacts the end of the motor stator fixed at the end of the wire embedding column 2, so as to perform a moving limit on the motor stator. Then, the main body housing 1 can be used to push the coil placed inside the wire embedding column 2 into the inner cavity of the motor stator to complete the wire embedding operation. When performing wire embedding operations on motor stators of different specifications, by applying a pressing force to the pressing block 601, the stressed pressing block 601 synchronously drives the push rod 603 to move and applies a squeezing force to the spring 602. The moving push rod 603 synchronously drives the guiding block 604 to move. The cylindrical rod of the guiding block 604 in the inner cavity of the guiding groove 606 will apply a squeezing thrust to the guiding groove 606, causing the guiding groove 606 to approach each other under the thrust from the guiding block 604. The moving movable blocks 605 will synchronously drive the limiting blocks 607 fixed on the outer wall to move, so that the limiting blocks 607 move out of the inner cavity of one limiting ring groove 608, thereby releasing the connection limit of the rotary pressing rod 4 and the movable column 5. At this time, an outward pulling force can be applied to the movable column 5 to drive the movable column 5 to axially move along the inner cavity of the rotary pressing rod 4, and the position of the movable column 5 can be adjusted at this angle to match motor stators of different specifications.

[0045] Please refer particularly to Figures 1-3 , the inner side of the limiting ring groove 608 matches the outer wall of the limiting block 607. The number of the limiting ring grooves 608 is set to be multiple, and the multiple limiting ring grooves 608 are evenly distributed inside the rotary pressing rod 4. The outer wall of the guiding groove 606 is integrally inclined. The two guiding grooves 606 are symmetrically distributed up and down on the outer walls of the two movable blocks 605. The outer wall of the guiding block 604 is integrally in a "square" - shaped structure. The contact surface between the guiding block 604 and the guiding groove 606 is in a cylindrical structure. The outer wall of the pressing block 601 is integrally in a "cross" - shaped structure. A chute for the vertical movement of the pressing block 601 is formed in the inner cavity of the movable column 5.

[0046] In this embodiment: When the guiding block 604 is axially moved through this structure, the end of the cylindrical guiding block 604 will contact the guiding groove 606 and apply a squeezing force to the guiding groove 606. The inclined guiding groove 606 transmits the thrust to the movable block 605, causing the movable block 605 to vertically move along the inner cavity of the movable column 5. And the limiting block 607 that moves out of the inner cavity of the rotary pressing rod 4 will no longer limit the rotation and movement of the movable column 5, so that the angle and length of the movable column 5 can be quickly adjusted.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
