Description

Technical Field

[0001] This utility model belongs to the field of rotor testing technology, specifically relating to an auxiliary device for rotor testing in generator production. Background Technology

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. The generator needs to have a rotor inside. After the rotor is manufactured, it needs to be tested. The rotor needs to be fixed before testing.

[0003] When fixing the rotor, two clamps are needed to hold both ends of the rotor. Since the rotors of some large generators are heavy, they need to be suspended by lifting equipment. The rotor will swing when it is suspended, which makes it inconvenient to align the clamps and hold them, and makes it difficult to fix the rotor quickly.

[0004] Therefore, an auxiliary device for rotor testing in generator production is proposed. Summary of the Invention

[0005] This utility model provides an auxiliary device for rotor testing in generator production, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a rotor testing auxiliary device for generator production, including a base; a rotor support assembly and a rotor clamping and lifting assembly disposed on the top of the base, the rotor support assembly being located on one side of the rotor clamping and lifting assembly; wherein, the rotor support assembly includes: a spring disposed on the top of the base; a support platform disposed on the top of the spring; a slot opened at the center of the top of the support platform; and a fixed guide platform disposed on the outer wall of the support platform; and a lower inclined surface opened at one end of the top of the fixed guide platform; wherein, the rotor clamping and lifting assembly includes: an electric three-jaw chuck disposed on one side of the support platform; a movable guide platform disposed on the outer wall of the electric three-jaw chuck; and an upper inclined surface opened at one end of the bottom of the movable guide platform.

[0007] Furthermore, the rotor clamping and lifting assembly also includes a pressure plate located at the bottom of the electric three-jaw chuck. A support platform is provided on one outer wall of the pressure plate. A movable seat is slidably connected to the top of the base. An electric push rod is provided on the top of the movable seat. The output end of the electric push rod is fixedly connected to the bottom of the support platform.

[0008] Furthermore, the rotor support assembly also includes a fixing sleeve located on the top of the base near the spring side, with a lifting column embedded in the center of the top of the fixing sleeve, and the top of the lifting column being fixedly connected to the bottom of the support platform.

[0009] Furthermore, the cross-section of the slot is an isosceles trapezoid;

[0010] By adopting the above technical solution, the isosceles trapezoidal slot can be used to support and limit rotors of different models, preventing rotor swaying and ensuring the limiting position of the rotor support.

[0011] Furthermore, the lower inclined surface and the upper inclined surface are horizontal and fit together;

[0012] By adopting the above technical solution, the upper inclined surface can be pressed against and squeezed during horizontal movement, thereby causing the upper inclined surface to undergo relative displacement.

[0013] Furthermore, the movable seat is moved by an external linear drive structure;

[0014] By adopting the above technical solution, the movable seat can be moved, which in turn drives the rotor clamping and lifting assembly to move horizontally in a straight line, thereby causing the three-jaw chuck to move toward one end of the rotor.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention provides support for a suspended rotor after lifting using a rotor support assembly, and limits the rotor to prevent it from swinging in mid-air. It also provides a straight clamping path for subsequent clamping of the rotor, ensuring that one end of the rotor can be inserted into an electric three-jaw chuck. Through the cooperation of the moving guide table and the fixed guide table, when the electric three-jaw chuck moves towards the rotor, under the guidance of the inclined surface, the inclined pressure causes the support table to move vertically downward, ensuring that the electric three-jaw chuck fits on the outside of one end of the rotor, achieving precise clamping. The clamping operation is simple and convenient, and can achieve rapid clamping and fixation.

[0017] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1-4 This utility model embodiment proposes a rotor testing auxiliary device for generator production, including a base 1. The top of the base 1 is provided with a fixing sleeve 21 of the rotor support assembly 2. A lifting column 22 is embedded in the center of the top of the fixing sleeve 21. The top of the lifting column 22 is provided with a support platform 23. A slot 24 is opened in the center of the top of the support platform 23. The cross-section of the slot 24 is an isosceles trapezoid. Using the isosceles trapezoidal slot 24, different models of rotors 4 can be supported and limited to prevent the rotors 4 from shaking and ensure the limited position of the rotors 4. A spring 25 is provided between the bottom of the support platform 23 and the top of the base 1 near the fixing sleeve 21. Two fixed guide platforms 26 are symmetrically arranged on the outer side wall of the support platform 23. A downward inclined surface 27 is opened on one side of the top of the two fixed guide platforms 26.

[0026] A movable seat 31 of the rotor clamping and lifting assembly 3 is slidably connected to the top of the base 1 near the fixed sleeve 21. The movable seat 31 is moved by an external linear drive structure, which can push the movable seat 31 to move, thereby pushing the rotor clamping and lifting assembly 3 to move horizontally and linearly, so that the electric three-jaw chuck 35 moves toward one end of the rotor 4. Two electric push rods 32 are symmetrically arranged on the top of the movable seat 31. The two electric push rods 32 are fixedly connected to a support platform 33 through the output end on one side. A pressure plate 34 is arranged on one side of the outer wall of the support platform 33. An electric three-jaw chuck 35 is arranged on the top of the pressure plate 34 near one side. Two moving guide platforms 36 are symmetrically arranged on the outer wall of the electric three-jaw chuck 35. An upper inclined surface 37 is opened on one side of the bottom of the moving guide platform 36. The lower inclined surface 27 and the upper inclined surface 37 are horizontal and cooperate with each other, so that the upper inclined surface 37 can fit and squeeze the upper inclined surface 37 during horizontal movement, thereby causing the upper inclined surface 37 to move relative to the other side.

[0027] A rotor 4 is disposed above the rotor support assembly 2.

[0028] The specific implementation method is as follows: Before testing the rotor 4, the rotor 4 needs to be assisted in fixing. The rotor 4 is lifted by external lifting equipment and placed on the rotor support assembly 2. The rotor 4 falls into the slot 24 at the top of the support platform 23. The isosceles trapezoidal slot 24 is used to support and limit the rotor 4. After the rotor 4 is supported.

[0029] The rotor clamping and lifting assembly 3 is moved horizontally in a linear motion by an external linear drive structure. The moving seat 31 moves toward the rotor 4, and the electric three-jaw chuck 35 moves synchronously. As the electric three-jaw chuck 35 moves, the moving guide table 36 moves synchronously. When the moving guide table 36 contacts the fixed guide table 26 on the support platform 23, under the guidance of the lower inclined surface 27 and the upper inclined surface 37, and under the vertical guidance of the fixed sleeve 21 and the lifting column 22, the moving guide table 36 presses against the fixed guide table 26 as it moves linearly, causing the fixed guide table 26 to move downwards. When the spring 25 is compressed, the electric three-jaw chuck 35 presses the support platform 23 down, and the pressure plate 34 applies pressure to the support platform 23 so that it cannot move upward. The electric three-jaw chuck 35 is fitted onto one end of the rotor 4, and the electric three-jaw chuck 35 is used to clamp one end of the rotor 4. After the two ends of the rotor 4 are clamped, the electric push rod 32 is controlled to drive the support platform 33 to move upward through its output end on one side. The electric three-jaw chuck 35 moves upward synchronously. The rotor 4 is in a clamped and suspended state. Subsequently, the rotor 4 is tested for circumference, length and other parameters.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
