Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a rotor clamp suitable for different specifications. Background Technology

[0002] Currently, a generator is a mechanical device that converts other forms of energy into electrical energy. Generators have wide applications in industrial and agricultural production, national defense, science and technology, and daily life. There are many types of generators, but their working principles are all based on the laws of electromagnetic induction and electromagnetic force. Therefore, the rotor is an important component of the generator. During the production process, processes such as dynamic balancing measurements require clamping the rotor, and in some cases, the rotor also needs to be able to rotate.

[0003] However, existing fixtures are generally only used for one type of rotor. If a different model is needed, the fixture also needs to be changed, which is inefficient and inconvenient for production. Utility Model Content

[0005] To achieve the above objectives, the technical solution of this utility model is a rotor clamp suitable for different specifications, including a base, and further comprising:

[0006] An octagonal frame is installed on the base. Its interior is an octagonal groove. Movable baffles are set on both sides of the four corners inside the frame. An electric push rod is installed between the movable baffles and the octagonal frame. The electric push rod is located at both ends of one side of the movable baffle.

[0007] An adjusting sleeve is installed at the center of one side of the movable baffle. An adjusting bolt is threaded onto one end of the sleeve, and a pressing baffle is installed inside it.

[0011] The drive groove is located inside the clamping telescopic rod, and a micro geared motor is installed inside it. A square shaft is installed on the rotating end of the micro geared motor, and the square shaft is slidably inserted into the square transmission groove.

[0012] As a rotor clamp suitable for different specifications, the compression spring is always in a compressed state.

[0013] As a rotor clamp suitable for different specifications, the electric push rod pushes the movable baffle to move, so that the clamp seat or rolling clamp seat approaches and contacts the rotor assembly.

[0014] As a rotor clamp suitable for different specifications, after the clamp seat or rolling clamp seat comes into contact with the rotor assembly, it pushes the clamping telescopic rod to fully retract into the adjusting sleeve, thereby clamping the rotor assembly.

[0028] 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.

[0029] This utility model provides a technical solution, such as Figures 1-4 As shown; a rotor clamp suitable for different specifications includes a base 1 and an annular frame 2, which is installed above the base 1. The frame is octagonal in shape and has an octagonal clamping groove inside. Movable baffles 21 are provided on both sides of the four corners inside the frame. An electric push rod 22 is installed between the movable baffle 21 and the annular frame 2. The electric push rod 22 is located at both ends of one side of the movable baffle 21.

[0030] In this embodiment of the utility model, the octagonal ring frame 2 allows the rotor assembly to be inserted into the octagonal clamping groove when fixed, and then the adjustable clamping mechanism 3 clamps the rotor assembly, which effectively facilitates the use of the operator and improves the aesthetics and practicality of the device.

[0031] In this embodiment of the utility model, the electric push rod 22 is used to push the movable baffle 21 to move, so that it can drive the adjustable clamping mechanism 3 to approach and clamp the rotor assembly, so that the device can clamp rotor assemblies of different diameters and improve the application range of the device.

[0032] Adjusting sleeve 23 is installed at the center of one side of movable baffle 21. One end of it is threaded with adjusting bolt 231, and a compression baffle 232 is provided inside it. The compression baffle 232 is movably connected to the adjusting bolt 231. The other end of it is movably inserted with clamping telescopic rod 233. One end of clamping telescopic rod 233 is equipped with clamping baffle 234. Clamping baffle 234 is located inside adjusting sleeve 23. Compression spring 235 is provided between clamping baffle 234 and compression baffle 232.

[0033] In this embodiment of the utility model, the compression baffle 232 and the clamping baffle 234 are configured to compress the compression spring 235. The compression of the compression spring 235 keeps the clamping telescopic rod 233 under a certain compressive force, thereby ensuring the clamping force of the rotor assembly, preventing it from being deformed due to excessive force, and ensuring the clamping effect of the rotor assembly and improving the clamping efficiency.

[0034] In this embodiment of the utility model, the threaded connection between the adjusting bolt 231 and the adjusting sleeve 23 is used to adjust the position of the extrusion baffle 232, thereby adjusting the clamping force of the rotor assembly and avoiding excessive or insufficient clamping force.

[0035] An adjustable clamping mechanism 3 is located at one end of the clamping telescopic rod 233. It includes: a clamping seat 31, which is installed at one end of the clamping telescopic rod 233. It is U-shaped, with anti-slip clamping blocks 311 installed at both ends of its lower surface. Clamping pads 312 are provided on the outer side of the anti-slip clamping blocks 311; a rolling clamping seat 32, which is slidably installed in the clamping seat 31. Clamping rollers 321 are provided at both ends of its lower interior. Roller pads 322 are provided on the outer surface of the clamping rollers 321. An adjusting screw 323 is movably installed at its upper end. The adjusting screw 323 is threaded into the clamping telescopic rod 233. A square transmission groove 324 is opened at the center of the adjusting screw 323; and a driving groove 33, which is opened inside the clamping telescopic rod 233. A micro geared motor 331 is installed inside the groove. A square rotating shaft 332 is installed at the rotating end of the micro geared motor 331. The square rotating shaft 332 is slidably inserted into the square transmission groove 324.

[0036] In this embodiment of the utility model, the anti-slip clamping blocks 311 at the lower ends of both sides of the clamping seat 31 can be used to clamp the rotor assembly after the clamping seat 31 comes into contact with it, so that the rotor assembly is in a fixed state. At the same time, the clamping pads 312 can be used to protect the rotor assembly, so as to prevent the rotor assembly from being worn and deformed after clamping, and to ensure the integrity of the rotor assembly.

[0037] In this embodiment of the utility model, the rolling clamp seat 32 provided inside the clamp seat 31 can extend out of the clamp seat 31, so that the clamping roller 321 clamps the rotor assembly. The rolling property of the clamping roller 321 allows the rotor assembly to rotate after clamping, so as to perform dynamic balancing measurement and other processes, thereby improving the application range of the device.

[0038] In this embodiment of the utility model, a micro geared motor 331 is used to drive the rotation of a square rotating shaft 332, and the square rotating shaft 332 is slidably connected to a square transmission groove 324, so that it can drive the adjusting screw 323 to rotate, thereby controlling the lifting and lowering of the rolling clamp seat 32, making it more convenient for workers to use.

[0039] In this invention, the compression spring 235 is always in a compressed state; this ensures the clamping force when the rotor assembly is clamped, and also prevents the adjustable clamping mechanism 3 from shaking, thus ensuring the stability of the device.

[0040] In this invention, the electric push rod 22 pushes the movable baffle 21 to move, so that the clamp seat 31 or the rolling clamp seat 32 approaches and contacts the rotor assembly; this allows it to quickly clamp the rotor assembly, and the appropriate clamping method can be selected according to the actual situation.

[0041] In this invention, after the clamp seat 31 or the rolling clamp seat 32 comes into contact with the rotor assembly, it pushes the clamping telescopic rod 233 to fully retract into the adjusting sleeve 23, thereby clamping the rotor assembly; ensuring the clamping force of the rotor assembly, preventing it from being deformed due to excessive clamping force, and improving clamping efficiency.

[0042] In this utility model, strip-shaped adjustment holes 24 are opened on both sides of the annular frame 2, and the strip-shaped adjustment holes 24 correspond to the positions of the adjustment sleeve 23; this allows the staff to conveniently use tools to adjust the adjustment bolt 231 in order to adjust the elasticity of the compression spring 235.

[0043] In this invention, when the rolling clamp seat 32 is retracted into the clamp seat 31, the clamping roller 321 is completely retracted into the clamp seat 31; this ensures that when the anti-slip clamping block 311 clamps the rotor assembly, the clamping roller 321 will not affect the clamping of the anti-slip clamping block 311.

[0044] When using this utility model, the staff installs the base 1 in the corresponding position and connects the device to the external power supply and controller, thereby using the power supply from the external power supply and controlling the operation of the electric push rod 22 and the micro geared motor 331 through the controller.

[0045] When the rotor assembly needs to be clamped, depending on the actual situation, if the rotor assembly does not need to rotate after clamping, the operator can directly control the electric push rod 22 to move the clamp seat 31 close to the rotor assembly and make contact with the rotor assembly through the anti-slip clamping block 311. Then, by continuing to work with the electric push rod 22, the rotor assembly squeezes the clamp seat 31, causing the clamp seat 31 to drive the clamping telescopic rod 233 to gradually retract into the adjusting sleeve 23. This causes the clamping baffle 234 to push the compression spring 235 to retract, gradually increasing its elastic force. When the clamping telescopic rod 233 is fully retracted, the elastic force provided by the compression spring 235 causes the clamping telescopic rod 233 to push the clamp seat 31 to clamp the rotor assembly, so that the anti-slip clamping block 311 and the clamping pad 312 clamp the rotor assembly.

[0046] When the rotor assembly needs to be rotated after clamping, the operator first controls the micro-motor 331 to drive the U-shaped rotating shaft 332 to rotate. Then, the square rotating shaft 332 drives the adjusting screw 323 to rotate. The adjusting screw 323 is connected to the clamping telescopic rod 233 by a thread, so that the adjusting screw 323 gradually extends out of the clamping telescopic rod 233, thereby driving the rolling clamp seat 32 to descend and gradually extend out of the clamp seat 31. The clamping roller 321 gradually moves out of the clamp seat 31. When a certain part of the clamping roller 321 is exposed, the micro-motor 331 can be controlled to work.

[0047] Then, the electric push rod 22 is operated to make the clamp seat 31 drive the rolling clamp seat 32 to approach and contact the rotor assembly. Subsequently, the electric push rod 22 continues to operate, causing the rotor assembly to squeeze the rolling clamp seat 32. Then, by the contraction of the clamping telescopic rod 233, the compression spring 235 is contracted. After the clamping telescopic rod 233 is fully contracted, the compression spring 235 provides sufficient elastic force, which in turn causes the clamping roller 321 to fully squeeze the rotor assembly and clamp it. By utilizing the free rotation property of the clamping roller 321, the rotor assembly can rotate after being clamped.
