Description

Technical Field

[0001] The utility model relates to the technical field of wind power synchronous drive motors, in particular to a stator winding detection bench for a wind power synchronous generator. Background Technique

[0002] A wind power synchronous drive motor is a special synchronous drive motor, which is mainly used to convert wind energy into electrical energy. It consists of two major parts: a fixed stator and a rotating rotor. In order to ensure the normal operation of the wind power synchronous drive motor, it is relatively important whether the stator winding is prepared qualified. Therefore, it is necessary to detect the stator winding. The qualified stator winding is assembled onto the wind power synchronous drive motor for use.

[0003] Among them, the publication number is CN202735371U, named a stator winding detection bench for a synchronous drive motor, including: a test bench frame, a support plate, a tooling rotor, a drive motor and an air pump. An opening for the tooling rotor to pass through is provided in the center of the support plate, and it is arranged on the top surface of the test bench frame and can be lifted up and down by the drive of the air pump; the tooling rotor is vertically arranged through the top surface of the test bench frame; during detection, the stator to be detected fixed on the support plate descends and fits onto the tooling rotor, and rotates in the stator to be detected under the drive of the drive motor. This stator winding detection bench for a synchronous drive motor has a simple and reasonable structure and high detection efficiency; there is no need to install the stator and rotor of the drive motor into the drive motor housing and then detect, avoiding the influence on the assembly efficiency due to disassembling the drive motor housing when detecting problems with the stator winding.

[0004] When the above-mentioned prior art fixes the stator and the rotor, its fixing components are driven one by one singly. As a result, when the stator or the rotor is assembled, position deviation will occur due to uneven force, and it cannot ensure that the vertical lines of the stator and the rotor coincide, affecting the accuracy of stator detection. Therefore, we propose a stator winding detection bench for a wind power synchronous generator to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a stator winding detection bench for a wind power synchronous generator to solve the problem in the above-mentioned background technique that when fixing the stator and the rotor in the current market, its fixing components are driven one by one singly, resulting in position deviation due to uneven force during the assembly of the stator or the rotor, and it cannot ensure that the vertical lines of the stator and the rotor coincide, affecting the accuracy of stator detection.

[0006] To achieve the above object, the utility model provides the following technical solutions: a detection bench for the stator winding of a wind synchronous generator, including a support bench. A driving motor is installed on the lower side of the support bench. The output end of the driving motor is connected to a rotating rod. A moving rod is slidably connected inside the rotating rod. An extension plate is installed at the lower end of the moving rod. A limiting rod is installed at the end of the extension plate. A limiting ring is sleeved on the outer side of the upper end of the limiting rod. A hydraulic rod a is installed on the lower side surface of the support bench. The output end of the hydraulic rod a is connected to the limiting ring;

[0007] A placing seat is installed at the upper end of the rotating rod. The inner side wall of the placing seat is connected to a first sliding rod. An inner pressing seat is slidably connected on the outer side of the first sliding rod. An adjusting rod is hinged on the outer side of the inner pressing seat. The end of the adjusting rod away from the inner pressing seat is hinged to the moving rod;

[0008] A hydraulic rod b is installed at the right end of the support bench. The output end of the hydraulic rod b is connected to a moving ring. A second sliding rod is connected inside the moving ring. A slider is slidably connected on the outer side of the second sliding rod. An outer pressing seat is installed at the upper end of the slider;

[0009] An adjusting ring is rotatably connected inside the moving ring. A dial rod is connected to the outer side of the adjusting ring. The dial rod and the moving ring are fixed by bolts. A convex block is connected to the inner side of the adjusting ring.

[0010] Preferably, the end of the extension plate penetrates through the rotating rod and is slidably connected to the rotating rod. The extension plate and the limiting ring form a rotating structure through the limiting rod. The limiting rod is a "T" - shaped structure. This design can ensure that when the extension plate rotates with the rotating rod, the extension plate and the limiting ring are continuously connected, guaranteeing that the limiting ring drives the extension plate later, thus facilitating the driving of the moving rod to move inside the rotating rod.

[0011] Preferably, the vertical center line of the limiting ring coincides with the vertical center line of the rotating rod. The inner diameter of the limiting ring is larger than the outer diameter of the rotating rod. This design can ensure the smooth rotation of the rotating rod and prevent the connection between the limiting ring and the extension plate from blocking the rotation of the rotating rod.

[0012] Preferably, the inner pressing seat is a side "T" - shaped structure. The inner pressing seats are equally - angularly distributed about the longitudinal center line of the placing seat. This design can use the equally - angularly distributed inner pressing seats to fix the rotor with balanced force.

[0013] Preferably, the inner diameter of the moving ring is larger than the outer diameter of the placing seat. The outer pressing seats with an "L" - shaped structure are equally - angularly distributed on the moving ring. This design can ensure that the moving ring moves smoothly and is sleeved outside the placing seat for positioning, and thus use the equally - angularly distributed outer pressing seats to fix the stator with balanced force.

[0014] Preferably, the slider passes through the upper side surface of the movable ring and is slidably connected to the movable ring. The position of the slider and the position of the protrusion are set in a one-to-one correspondence. The contact between the protrusion and the movable ring is a smooth arc structure. This design can utilize the protrusion to drive the slider and control the slider to drive the external pressure seat to move.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The wind synchronous generator stator winding test bench can drive the extension plate to move downward by controlling the hydraulic rod a to push the limit ring downward, thereby controlling the moving rod to move downward, pulling the hinged adjustment rod to rotate, and then pulling the inner pressure seats to move closer to each other. The inner pressure seats distributed at equal angles simultaneously squeeze and fix the rotor, so that the rotor is subjected to balanced force, avoiding rotor deviation, and making the vertical center of the rotor coincide with the vertical center of the rotating rod, so that the subsequent stator can be stably and adaptably mounted on the outside of the rotor, and the magnetic flux lines generated by the rotation of the rotor can be ensured to be stable;

[0017] (2) The wind synchronous generator stator winding detection bench can drive the adjusting ring to rotate by driving the lever, so as to drive the convex block to push the slider, thereby synchronously driving the outer pressure seat with equal angle distribution to move, and squeezing and fixing the stator, so that the stator is subjected to balanced force, the vertical center of the stator and the vertical center of the rotor coincide, and further ensure that the stator is perfectly fitted to the outside of the rotor, and the distance between the stator and the rotor is the same, so as to avoid detection errors caused by position deviation and improve the accuracy of stator winding detection.

[0029] The end of the extension plate 5 passes through the rotating rod 3 and is slidably connected to the rotating rod 3. The extension plate 5 forms a rotating structure with the limiting rod 6 and the limiting ring 7 through the limiting rod 6, and the limiting rod 6 is a "T"-shaped structure; the vertical center line of the limiting ring 7 coincides with the vertical center line of the rotating rod 3, and the inner diameter of the limiting ring 7 is larger than the outer diameter of the rotating rod 3; the inner pressure seat 10 is a side "T"-shaped structure, and the inner pressure seat 10 is distributed at equal angles with respect to the longitudinal center line of the placement seat 20; the inner diameter of the moving ring 13 is larger than the outer diameter of the placement seat 20, and the outer pressure seats 16 of "L"-shaped structure are distributed at equal angles on the moving ring 13; the slider 15 passes through the upper side surface of the moving ring 13 and is slidably connected to the moving ring 13, and the position of the slider 15 and the position of the protrusion 19 are set one by one, and the contact between the protrusion 19 and the moving ring 13 is a smooth arc structure.

[0030] Working principle: when using the wind synchronous generator stator winding inspection bench, the rotor is placed on the inner pressure seat 10, the hydraulic rod a8 is opened, and the limit ring 7 is pushed down, thereby pressing the extension plate 5 to drive the moving rod 4 to move down, and the moving rod 4 pulls the hinged adjusting rod 9 to rotate, thereby pulling the inner pressure seat 10 to move to a position close to the center of the moving rod 4, and at the same time, the inner pressure seat 10 slides on the first slide bar 11 to ensure the horizontal movement of the inner pressure seat 10. The inner pressure seats 10 distributed at equal angles synchronously squeeze and fix the rotor so that the rotor is balanced in force, the hydraulic rod b12 is opened, the moving ring 13 is pushed up, and the stator is placed in the middle position of the moving ring 13.

At this time, it can be observed from the electronic instrument whether the electromotive force emitted by the output line meets the requirements, thereby judging whether the winding inside the stator is wound properly;
