Description

Technical Field

[0001] This utility model belongs to the technical field of rotor processing equipment, and in particular relates to a rotor locking device. Background Technology

[0002] In the manufacturing process of motors, the rotor, as the core rotating component, directly determines the motor's performance, noise, and service life through its machining accuracy (such as dynamic balancing, journal dimensions, bearing accuracy, and machining of magnetic rings or winding slots). To achieve precision machining on high-speed lathes, grinders, or dynamic balancing machines, the rotor must be securely and accurately fixed without damaging its critical surfaces. This is the core function of the rotor locking and fixing device. The production and processing of the rotor requires a winding machine. Before winding the rotor, a clamping mechanism is needed to clamp and position it, transferring it to the winding position. Then, the winding mechanism on the winding machine winds the rotor. However, existing rotor clamping mechanisms are unstable and have complex structures, making rotor loading and unloading operations during production difficult. Utility Model Content

The mounting rod is slidably mounted in the locking sleeve, and one end of the mounting rod is connected to the connecting shaft. The deformable connecting part is disposed at the other end of the mounting rod. The deformable connecting part has three elastic pieces extending away from the mounting rod. The three elastic pieces are spaced apart and surround the end of the mounting rod. Each limiting head is disposed at the end of each elastic piece. Each limiting head is located outside the locking sleeve, and each limiting head can be partially moved into the locking sleeve.

[0006] Preferably, a locking through hole is provided through the locking nozzle sleeve, and an annular guide slope is provided on the inner side of one end of the locking through hole.

[0009] Preferably, a limiting groove is provided on the side of the locking sleeve, and one end of the limiting pin extends outward through the limiting groove.

[0010] Preferably, the sliding frame further includes a front mounting plate, a rear mounting plate, and two guide rods. Both guide rods are slidably connected to the mounting frame, and the connecting shaft is located between the two guide rods. The two ends of the two guide rods are respectively fixedly connected to the front mounting plate and the rear mounting plate. The locking sleeve is rotatably mounted on the front mounting plate, and the telescopic end of the cylinder is connected to the rear mounting plate.

[0011] Preferably, the mounting bracket is provided with two sliding sleeves, which are respectively sleeved on the two guide rods, and both sliding sleeves are fixedly installed on the mounting bracket.

[0012] Preferably, the mounting bracket is provided with a protective sleeve, which covers one end of the connecting shaft. The cylinder is fixedly mounted on the protective sleeve, and the transmission belt extends into the protective sleeve and is connected to one end of the connecting shaft for transmission.

[0013] Preferably, the mounting bracket is provided with a clearance hole, and the rotary motor is located in the clearance hole.

[0014] The rotor locking device provided in this embodiment of the utility model has at least one of the following technical effects:

[0015] The rotor locking device in this application is assembled from a mounting frame, a locking rod, a sliding frame, a cylinder, a connecting shaft, and a rotary motor. The mounting frame is slidably mounted near the top. A locking sleeve is rotatably mounted on one side of the mounting frame, and a connecting through hole is provided on this side of the mounting frame. The locking through hole on the locking sleeve communicates with this connecting through hole. The locking end of the locking rod extends beyond the locking sleeve. The connecting shaft is rotatably mounted on the mounting frame, and one end of the connecting shaft extends into the connecting through hole and connects to the end of the locking rod. The other end of the connecting shaft extends and is connected to the output end of the rotary motor, which is fixedly mounted on the mounting frame, via a transmission belt. The cylinder is fixedly mounted on the mounting frame, and the telescopic end of the cylinder extends away from the locking rod. The telescopic end of the cylinder is connected to the sliding frame and is used to push the sliding frame to move back and forth, thereby driving the locking sleeve to move. Relative to the movement of the locking sleeve, the locking rod... The end of the locking rod reciprocates within the locking sleeve. When the end of the locking rod leaves the locking sleeve, it opens; when it enters the locking through hole of the locking sleeve, it contracts and closes, gripping the rotor shaft end. In use, a drive cylinder pushes the sliding frame to move, which in turn moves the locking sleeve. The movement of the locking sleeve changes the relative position between the locking sleeve and the locking rod, thereby adjusting the relative position between the locking sleeve and the end of the locking rod. As the end of the locking rod enters the locking through hole, the inner wall of the locking through hole squeezes and tightens the end of the locking rod, thus clamping the rotor shaft end. After clamping, a rotary motor drives the connecting shaft to rotate via a transmission belt. The rotation of the connecting shaft drives the locking rod to rotate, which in turn drives the locking sleeve to rotate, thus completing the rotation operation of the rotor clamped at the end of the locking rod. Through the above structural design, the rotor locking device structure is simplified. Attached Figure Description

[0031] In one embodiment of this utility model, such as Figures 1-2 As shown, a rotor locking device is provided, which is assembled from a mounting frame 10, a locking rod 20, a sliding frame 30, a cylinder 40, a connecting shaft 50, and a rotary motor 60. The mounting frame 10 contains a carrier plate located at its bottom. A vertical plate is mounted on the carrier plate, and the vertical plate has a clearance hole, a rotating mounting hole, and two assembly holes. The clearance hole is located near the center of the vertical plate, while the rotating mounting hole and the two assembly holes are located near the top of the vertical plate. The rotating mounting hole is located below the two assembly holes, and the two assembly holes are located near the sides of the vertical plate. An assembly plate is fixedly mounted on the mounting frame 10, located at the clearance hole. The rotary motor 60 is fixedly mounted on this assembly plate. A through hole is provided on the assembly plate, through which the rotating shaft of the rotary motor 60 passes, and the rotary motor 60 is located within the clearance hole. An auxiliary wheel is provided on the rotating end of the rotary motor 60. Figure 2 As shown, the locking lever 20 is rotatably mounted in the rotary mounting hole. An auxiliary wheel is also provided at one end of the locking lever 20, and the two auxiliary wheels are located on the same side of the mounting bracket 10. A transmission belt is fitted onto the two auxiliary wheels. The rotating end of the rotary motor 60 rotates, driving one auxiliary wheel to rotate. The transmission belt causes the two auxiliary wheels to rotate synchronously, thereby driving the locking lever 20 to rotate. Figure 1As shown, a protective sleeve 11 is fixedly installed on the side of the mounting bracket 10. The protective sleeve 11 covers one end of the locking rod 20 where the auxiliary wheel is located. The cylinder 40 is fixedly installed on the outer surface of the protective sleeve 11, and the protective sleeve 11 is located between the mounting bracket 10 and the cylinder 40. The telescopic end of the cylinder 40 is set away from the mounting bracket 10. Two sliding sleeves 12 are provided on the mounting bracket 10. The two sliding sleeves 12 are located on the same side as the protective sleeve 11, and the two sliding sleeves 12 respectively cover and connect two assembly holes. The two guide rods 33 of the sliding bracket 30 pass through one sliding sleeve 12 and one assembly hole respectively, and the guide rods 33 are slidably connected to the sliding sleeve 12 and the assembly hole. The front mounting plate 3 of the sliding bracket 30 1. The rear mounting plate 32 is located at both ends of the two guide rods 33. One end of each guide rod 33 is connected to a side of the front mounting plate 31 near both ends, and the other end of each guide rod 33 is connected to a side of the rear mounting plate 32 near both ends. The telescopic end of the cylinder 40 is connected to the side of the rear mounting plate 32. The telescopic end of the cylinder 40 pushes the rear mounting plate 32 to move. The rear mounting plate 32 drives the two guide rods 33 to slide on the two assembly holes of the mounting bracket 10 and the sliding sleeve 12. A connecting hole is opened on the front mounting plate 31. A locking sleeve 311 is rotatably mounted on the front mounting plate 31. The front mounting plate 31 is located between the locking sleeve 311 and the mounting bracket 10. Figure 2 As shown, a locking through hole is provided through the locking sleeve 311, which is connected to the connecting hole. One end of the locking rod 20 extends into the locking through hole and slides between it and the locking through hole. A limiting hole is opened on the side wall of the locking sleeve 311, which is connected to the locking through hole. A limiting pin 211 is inserted into the locking rod 20, with one end of the limiting pin 211 passing through the limiting hole. On the one hand, the end of the locking rod 20 located in the locking through hole is connected to the end of the connecting shaft 50. The rotation of the connecting shaft 50 drives the locking rod 20 to rotate, which in turn drives the locking sleeve 311 to rotate through the limiting pin 211. On the other hand, the cylinder 40 pushes the rear mounting plate 32 to move, which causes the locking rod 20 in the locking sleeve 311 mounted on the front mounting plate 31 to change position. The limiting pin 211 is restricted to move through the limiting hole, thereby limiting the relative position change stroke between the locking sleeve 311 and the locking rod 20.

[0032] like Figure 3As shown, one end of the mounting rod 21 on the locking rod 20 is connected to the connecting shaft 50, and the limiting pin 211 is inserted into the mounting rod 21. The other end of the mounting rod 21 is provided with a deformable connecting part 22, on which three elastic pieces 221 are formed. One end of the elastic piece 221 extends away from the locking sleeve 311, and the other end is provided with the deformable connecting part 22. The three elastic pieces 221 are arranged in a circle. A limiting head 23 is provided at the other end of each of the three elastic pieces 221. After the three limiting heads 23 are tightly closed together, they are engaged at the opening of the locking through hole. When the three limiting heads 23 move in the opposite direction to the outside of the locking sleeve 311, the three limiting heads 23 are spaced apart from each other. At this time, the rotor shaft can be detached and removed.

[0033] like Figure 2 As shown, an annular guide slope is formed on the inner side of the opening of the locking through hole. The annular guide slope is inclined outward in the direction of the opening. An outer slope that is in close contact with the annular guide slope is formed on the outer side of the three enclosing limit heads 23. The three limit heads 23 form a frustum shape after being enclosed.

[0034] In use, one end of the rotor shaft is inserted between the three limiting heads 23. The cylinder 40 pushes the mounting plate 32, which in turn moves the entire sliding frame 30 to retract the locking rod 20 into the locking sleeve 311. During the retraction of the locking rod 20, the three limiting heads 23 retract along the annular inclined plane to clamp the rotor shaft. After the rod is in place, the moving end of the cylinder 40 stops moving, and the rotary motor 60 is started to drive the connecting shaft 50 to rotate via the transmission belt. The connecting shaft 50 then drives the locking rod 20 to rotate. The rotation of the locking rod 20 drives the locking sleeve 311 to rotate, thus preventing the locking rod 20 from being restricted in rotation after entering the locking sleeve 311. This causes the rotor clamped at the end of the locking rod 20 to rotate at a certain angle, thereby simplifying the structure of the rotor locking device.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
