Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor technology, and more specifically, to a motor rotor rotation synchronization clamp. Background Technology
[0002] The motor rotor is the core rotating component of an electric motor, mainly composed of a rotor core, windings (or permanent magnets), shaft, and fan. Its function is to convert electrical energy into mechanical energy. Based on its structure, it can be divided into three main categories: squirrel-cage, wound-rotor, and permanent magnet. It is widely used in industrial motors, new energy vehicle drive systems, and household appliances. When the motor rotor is being machined, a rotary synchronous fixture is needed to hold the motor rotor.
[0003] For example, Chinese patent disclosure: A rotor clamp for a dynamic balancing machine, application number: CN201521053315.9, which includes a hinge bolt, a pressure cap, a support body, a cylindrical pin and a clamping nut. The support body and the pressure cap are fixedly connected by the cylindrical pin, the support body and the hinge bolt are fixedly connected by the cylindrical pin, and the hinge bolt and the pressure cap are detachably connected by the clamping nut.
[0004] However, in the above technical solutions, during the machining and manufacturing process of the motor rotor, especially during cutting processes such as turning and milling, the high-speed rotating rotor will generate a large amount of cutting waste. These wastes are easily splashed everywhere under the action of centrifugal force, which will not only pollute the working environment around the machine tool and increase the difficulty of cleaning, but may also pose a threat to the safety of operators. At the same time, the scattered wastes also bring inconvenience to the subsequent classification, collection, treatment and recycling. Utility Model Content
[0005] The main objective of this invention is to provide a synchronous clamping fixture for rotating motor rotors, which can effectively solve the problem in the background art where, during the processing and manufacturing of motor rotors, especially during cutting processes such as turning and milling, the high-speed rotating rotor generates a large amount of cutting waste. This waste is easily scattered everywhere under the action of centrifugal force, which not only pollutes the working environment around the machine tool and increases the difficulty of cleaning, but also may pose a threat to the safety of operators. At the same time, the scattered waste also brings inconvenience to the subsequent classification, collection, treatment and recycling.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a motor rotor rotation synchronization clamp, including a base, on which two support plates are fixedly mounted. A three-jaw chuck and a first through slot are provided on the support plates. The three-jaw chuck is rotatably connected to the support plates. The first through slot is located directly above the three-jaw chuck. An upper baffle is slidably mounted within the first through slot. A second through slot is provided on the upper baffle. A groove and two lower baffles are provided between the two support plates. The upper baffle and the two lower baffles together form a hollow cylinder. A handle is fixedly mounted on the outer wall surface of one side of the lower baffle. A collection frame is provided within the groove.
[0007] Preferably, the length of the upper baffle is greater than the length of the lower baffle, the two sides of the lower baffle are fixedly connected to the support plate, and the groove is located on the base.
[0008] Preferably, the lower baffle is located directly below the upper baffle, and the groove is located directly below the lower baffle.
[0009] Preferably, the lower baffle includes a lower baffle base, a rotating column is provided on one side of the lower baffle base, two threaded holes are provided on the side of the lower baffle base away from the rotating column, a screw is provided in any one of the threaded holes, and several sealing layers are provided on the outer wall surfaces of both sides of the lower baffle base.
[0010] Preferably, the rotating column is rotatably connected to the support plate.
[0011] Preferably, the screws in the two lower baffles are staggered.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] (1) When the motor rotor is cut, the two lower baffles and the upper baffle are used to shield the waste generated by cutting, preventing the waste from splashing to various places. Since the length of the upper baffle is greater than that of the lower baffle, the upper baffle and the two lower baffles can still wrap the motor rotor when the upper baffle moves with the external cutter, preventing the waste from splashing to various places and improving the working environment. After the motor rotor is processed, the screw is turned to make the screw leave the threaded hole, and the fixed connection between the two lower baffles is released. Then, the lower baffle base is moved by the handle, so that the lower baffle base rotates around the rotating column, so that the outer wall surfaces of one side of the two lower baffle bases are no longer attached together, thereby separating the two lower baffles. At this time, the waste blocked by the two lower baffles will fall into the collection box under the action of gravity, and the waste is collected, which is convenient for waste disposal and recycling.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0019] like Figure 1 and Figure 2 As shown, a motor rotor rotation synchronization clamp includes a base 1, on which two support plates 2 are fixedly mounted. A three-jaw chuck 4 and a first through slot 5 are mounted on the support plates 2. The three-jaw chuck 4 is rotatably connected to the support plates 2. The first through slot 5 is located directly above the three-jaw chuck 4. An upper baffle 6 is slidably mounted within the first through slot 5. A second through slot 7 is mounted on the upper baffle 6. A groove 9 and two lower baffles 8 are located between the two support plates 2. The upper baffle 6 and the two lower baffles 8 together form a hollow cylinder. A handle 10 is fixedly mounted on the outer wall surface of one side of the lower baffle 8. A collection frame 3 is mounted within the groove 9.
[0020] like Figure 3 As shown, in another embodiment of the present invention, the lower baffle 8 includes a lower baffle base 801, a rotating column 802 is provided on one side of the lower baffle base 801, two threaded holes 803 are provided on the side of the lower baffle base 801 away from the rotating column 802, a screw 804 is provided in any of the threaded holes 803, and a plurality of sealing layers 805 are provided on the outer wall surfaces of both sides of the lower baffle base 801.
[0021] When it is necessary to separate the two lower baffles 8, first turn the screw 804 so that the screw 804 leaves the threaded hole 803, thereby releasing the fixed connection between the two lower baffles 8. Then, move the lower baffle base 801 by the handle 10 so that the lower baffle base 801 rotates around the rotating column 802, so that the outer wall surfaces of one side of the two lower baffle bases 801 are no longer in contact, thereby separating the two lower baffles 8. At this time, the waste debris blocked by the two lower baffles 8 will fall into the collection frame 3 under the action of gravity, and the waste debris will be collected.
[0022] After collection is complete, rotate the lower baffle base 801 again to return it to its original position. Then, use screws 804 and threaded holes 803 to fix the two lower baffle bases 801 together, thereby using the two lower baffles 8 to seal off one side of the motor rotor and block the waste debris below the motor rotor.
[0023] The working principle of this type of motor rotor rotation synchronization clamp:
[0024] In use, first, the upper baffle 6 is moved to one side, so that it no longer closes the space between the two three-jaw chucks 4. Then, the two shafts on both sides of the motor rotor are inserted into the three-jaw chucks 4, and the three-jaw chucks 4 are used to fix the two shafts on both sides of the motor rotor. Then, the upper baffle 6 is returned to its original position, and the two lower baffles 8 and the upper baffle 6 are used to wrap the motor rotor. Then, the external machine drives the three-jaw chuck 4 to rotate, and then the external cutter passes through the second through slot 7 and approaches the motor rotor to cut the motor rotor. The two lower baffles 8 and the upper baffle 6 are used to shield the waste generated by cutting to prevent the waste from splashing everywhere. When the external cutter moves to one side to cut the motor rotor comprehensively, the external cutter pushes the upper baffle 6 to move. The upper baffle 6 is longer than the lower baffle 8. Therefore, when the upper baffle 6 moves with the external cutter, it can still wrap the motor rotor with the two lower baffles 8 to prevent waste chips from splashing everywhere and improve the working environment. After the motor rotor is processed, the screw 804 is turned so that the screw 804 leaves the threaded hole 803, and the fixed connection between the two lower baffles 8 is released. Then, the lower baffle base 801 is moved by the handle 10 so that the lower baffle base 801 rotates around the rotating column 802. This causes the outer wall surfaces of the two lower baffle bases 801 to no longer stick together, thus separating the two lower baffles 8. At this time, the waste chips blocked by the two lower baffles 8 will fall into the collection frame 3 under the action of gravity, and the waste chips are collected for easy waste chip processing and recycling.
[0025] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
