Description

Technical Field

[0001] This utility model relates to the field of rotor clamping technology, and in particular to a rotor clamping and rotating mechanism. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy into mechanical energy based on the law of electromagnetic induction. It converts electrical energy into mechanical energy, and its main function is to generate driving torque. As a power source for electrical appliances and various machines, it is an indispensable device in our lives. The electric motor structure mainly consists of two parts: the stator and the rotor. The stator is generally composed of permanent magnets and is stationary. The rotor is the centrally rotating core, composed of a rotor core, rotor windings, and a shaft. When the motor is working, the coils on the rotor are energized, generating electromagnetic induction. This induction causes like poles to repel and unlike poles to attract with the permanent magnets on the stator, thus causing the rotor to rotate at high speed.

[0003] The clamping and rotating mechanisms currently used in the market use a traditional finger cylinder plus gripper mechanism to clamp the rotor. This structure has the problem that when clamping the rotor, due to the accumulation of tolerances in the machining and assembly of the finger cylinder parts, there will be a large deviation between the rotor center axis and the actual rotation axis. There is a risk of vibration and imbalance during rotation. If there is a large deviation between the rotor center axis and the actual rotation axis, the rotor can be easily damaged.

[0009] A rotary drive device is provided below the horizontal moving device, and the drive end of the rotary drive device is connected to the sleeve through a transmission assembly.

[0010] Preferably, the mounting head includes a plurality of locking blocks and a plurality of locking slots, wherein the plurality of locking blocks are disposed on one side of the first guide rod, and the plurality of locking slots are disposed on the corresponding inner side of the locking blocks.

[0011] Preferably, the slot is arc-shaped, and there is a gap between the plurality of the card blocks.

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

[0016] This invention, through its mounting head, allows the rotor to be installed in use. A horizontal moving device moves a first locking block within a groove, causing a first guide rod to move within a first and second connecting rod. This, in turn, moves the mounting head into the inner cavity of the second connecting rod, clamping the rotor within the second connecting rod's cavity. A rotary drive device, via a transmission assembly, rotates a sleeve, which in turn rotates the first connecting rod and the first guide rod, thus driving the rotor to rotate. Compared to existing technologies, this device, through its horizontal moving device, moves the mounting head into the inner cavity of the second connecting rod to clamp the rotor. The rotary drive device then drives the rotor to rotate, keeping it centered on the rotation axis. This solves the problem in existing technologies where a large deviation between the rotor's central axis and the actual rotation axis can easily damage the rotor. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 5 A rotor clamping and rotating mechanism includes a mounting base 1, a horizontal moving device 2 is provided on one side of the mounting base 1, a first connecting rod 3 is rotatably provided on one side of the mounting base 1, a groove 4 is provided on one side of the first connecting rod 3, a first locking block 5 is movably provided in the groove 4, the driving end of the horizontal moving device 2 movably passes through the mounting base 1 and is connected to one side of the first connecting rod 3 and the first locking block 5, and a second connecting rod 6 is installed on one side of the first connecting rod 3 through a plug-in assembly;

[0025] A first guide rod 7 is provided on one side of the first card block 5, and one side of the first guide rod 7 movably passes through the first connecting rod 3 and the second connecting rod 6. An installation head 8 is installed on the first guide rod 7, and the installation head 8 is movably disposed in the inner cavity of the second connecting rod 6.

[0026] A sleeve 9 is movably sleeved on the outer periphery of the first connecting rod 3 and the second connecting rod 6. The sleeve 9 is provided with a plurality of openings 10. The insertion component and the first locking block 5 both extend through the openings 10 to the outside of the sleeve 9, and the first locking block 5 is fixedly connected to the inner cavity of the opening 10.

[0027] A rotary drive device 11 is provided below the horizontal moving device 2. The drive end of the rotary drive device 11 is connected to the sleeve 9 through a transmission assembly. The rotary drive device 11 is a rotary motor, and the horizontal moving device 2 is a cylinder.

[0028] Compared with the prior art, the rotor can be installed at the mounting head 8. The horizontal moving device 2 drives the first locking block 5 to move within the groove 4, which in turn drives the first guide rod 7 to move within the first connecting rod 3 and the second connecting rod 6. This causes the mounting head 8 to move into the inner cavity of the second connecting rod 6, where the mounting head 8 clamps the rotor. Then, the rotary drive device 11 drives the sleeve 9 to rotate via the transmission assembly. The first locking block 5 drives the first connecting rod 3 to rotate, which in turn drives the first guide rod 7 to rotate, thus rotating the rotor. Compared with the prior art, this device, through the horizontal moving device 2, can move the mounting head 8 into the inner cavity of the second connecting rod 6 to clamp the rotor. The rotary drive device 11 then drives the rotor to rotate, keeping the rotor at the center of the rotation axis. This solves the problem in the prior art where a large deviation between the rotor's central axis and the actual rotation axis can easily damage the rotor.

[0029] Furthermore, the mounting head 8 includes several locking blocks 12 and several locking slots 13. Several locking blocks 12 are disposed on one side of the first guide rod 7, and several locking slots 13 are disposed on the corresponding inner side of the locking blocks 12. Through the provided locking slots 13, one side of the rotor can be inserted into the locking slots 13. The horizontal moving device 2 drives the first guide rod 7 to move, which in turn drives the inner cavity of the second connecting rod 6 of the mounting base 1 box to move, so that the inner cavity of the second connecting rod 6 squeezes the locking blocks 12, thereby restricting the rotor within the locking slots 13.

[0030] Furthermore, the slot 13 is arc-shaped, and there is a gap between the several locking blocks 12. Through the gap between the locking blocks 12, the inner cavity of the second connecting rod 6 can squeeze the locking blocks 12, so that the gap between the locking blocks 12 disappears and the several locking blocks 12 abut against each other, thus clamping the rotor.

[0031] Furthermore, the transmission assembly includes a first pulley 14, a second pulley 15, and a transmission belt 16. The first pulley 14 is disposed at the drive end of the rotary drive device 11, and the second pulley 15 is rotatably disposed on one side of the mounting base 1. The sleeve 9 is connected to the inner cavity of the second pulley 15 through a sliding assembly. The rotary drive device 11 drives the first pulley 14 to rotate, and then the transmission belt 16 drives the second pulley 15 to rotate. The sliding assembly drives the sleeve 9 to rotate, and the first locking block 5 drives the first connecting rod 3 to rotate, which in turn drives the second connecting rod 6 to rotate, thus driving the rotor to rotate.

[0032] Furthermore, the sliding assembly includes a groove 17 and a slider 18. The groove 17 is disposed on the outer periphery of the sleeve 9, and the slider 18 is disposed on the inner periphery of the second pulley 15. The slider 18 is slidably connected to the groove 17. When the horizontal moving device 2 drives the first clamping block to move, the slider 18 on the second pulley 15 moves along the groove 17 through the groove 17 and the slider 18.

[0033] Furthermore, the plug-in assembly includes a plug 19 and a socket 20. The plug 19 is disposed on one side of the first connecting rod 3, and the socket 20 is disposed on one side of the second connecting rod 6. The socket 20 is adapted to the plug 19. A second locking block 21 is fixedly installed on one side of the first connecting rod 3. One side of the second locking block 21 is fixedly connected to one side of the second connecting plate. The plug 19 is inserted into the socket 20, and the first connecting rod 3 and the second connecting rod 6 are fixedly connected by the second locking block 21. Thus, when the first connecting rod 3 rotates, it can drive the second connecting rod 6 to rotate, thereby driving the rotor to rotate.

[0034] 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.
