Description

Technical Field

[0001] This utility model belongs to the field of motor rotor manufacturing technology, specifically a fixing device for producing flat wire oil-cooled motor rotors. Background Technology

[0002] An electric motor consists of two parts: a rotor and a stator. It is a device used to convert electrical energy into mechanical energy and vice versa. The motor rotor is the rotating part of the motor and is divided into electric motor rotor and generator rotor. During the production process, in order to ensure its stability, the motor rotor needs to be fixed to avoid shaking and affecting the installation accuracy.

[0003] For example, utility model CN213027753U discloses a fixing device for motor rotor production. Addressing the problem that existing fixing devices have low fixing efficiency for motor rotors, are time-consuming and labor-intensive, and reduce production efficiency, the following solution is proposed: It includes a fixing plate with two sliding holes on one side. A movable plate is slidably installed in each of the two sliding holes. A clamping plate is fixedly installed on one side of each of the two movable plates. A rack is fixedly installed on the side of the two movable plates that are close to each other. A gear is rotatably installed on one side of the fixing plate, meshing with the two racks. A base plate is fixedly installed on the other side of the fixing plate. A movable hole is opened on the top of the base plate, and a screw is slidably installed in the movable hole. The top end of the screw is fixedly connected to the bottom of the movable plate. This utility model has a reasonable structure, is easy to operate, and has high fixing efficiency for motor rotors, saving time and labor and improving production efficiency.

[0004] However, when the above-mentioned device uses two single moving plates to fix the motor rotor, the clamping surface of the moving plates is arc-shaped, which can only clamp and fix a single ordinary cylindrical electronic rotor. When it is necessary to fix a flat wire oil-cooled motor rotor, the flat wire oil-cooled motor rotor may have a specific shape and structure due to the integrated oil cooling system and the use of flat wire winding design, making it more compact and complex in appearance. At this time, the single arc-shaped clamp may cause unstable clamping due to the mismatch of the clamping surface shape. The existing clamping moving plates are relatively fixed and it is difficult to quickly replace them according to the shape of different electronic rotors, which can easily lead to reduced clamping accuracy and low clamping efficiency.

[0005] Therefore, a fixing device for producing flat wire oil-cooled motor rotors is proposed to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a fixing device for the production of flat wire oil-cooled motor rotors, which solves the problem that existing clamping devices are difficult to quickly replace the clamps according to the shape of different motor rotors, which easily leads to unstable clamping.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for producing flat wire oil-cooled motor rotors, comprising a base, mounting seats fixedly connected to both symmetrical sides of the top of the base, two symmetrical sliding seats slidably connected to the surface of the base, a connecting plate fixedly provided on the top of each of the two sliding seats, a slide rail fixedly connected to the surface of the connecting plate, a driving mechanism for driving the two sliding seats to move in opposite directions on the surface of the base provided on the mounting seat, a clamping block installed on the side of the two connecting plates that are close to each other, a slider fixedly connected to the surface of the clamping block, the slider being slidably connected to the slide rail, and mounting mechanisms for disassembling and assembling the clamping block provided on both symmetrical sides of the connecting plate;

[0008] The installation mechanism includes a slot and a plug. The slide and the slider are both provided with slots. The slots are slidably connected to the plug. A spring telescopic rod is fixedly connected to the side of the plug away from the slide. A fixing plate is fixedly connected to the end of the spring telescopic rod away from the plug. The fixing plate is fixedly connected to the connecting plate.

[0009] Preferably, an adjusting plate is fixedly connected to the end of the insert block away from the slot, and sliding grooves are provided on both symmetrical sides of the connecting plate, in which the adjusting plate slides.

[0010] Preferably, limiting components for limiting the adjustment plate are provided on both symmetrical sides of the connecting plate near the slide groove, and a limiting groove is provided at the end of the adjustment plate away from the insert block.

[0011] Preferably, the limiting component includes a limiting insert plate, which is fixedly connected to the connecting plate, and the limiting insert plate slides through the limiting groove and slides inside the limiting groove.

[0012] Preferably, a limiting block is rotatably connected to the side of the limiting plate near the adjusting plate, and the limiting block has the same shape and size as the limiting plate.

[0013] Preferably, the driving mechanism includes a screw, which is screwed to two sliding seats. Both ends of the screw are rotatably connected to the mounting base. One end of the screw passes through the mounting base and is fixedly connected to a control motor. The control motor is fixedly connected to the mounting base. Guide rods are fixedly connected to both symmetrical sides of the mounting base, and the guide rods are slidably connected to the sliding seats.

[0014] Preferably, the screw is fixedly connected to a sleeve at its center, and the threads of the screw on both sides of the sleeve are opposite.

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

[0016] This invention achieves rapid replacement of the clamping block through the combined use of a clamping block, a slot, an insert block, a spring telescopic rod, and a limiting component. By manually moving the adjusting plate along the slide groove away from the slider, the insert block slides out of the slot and moves out of the slider, making it easy to remove the clamping block for replacement. This solves the problem that existing clamping devices are difficult to quickly replace the clamps according to the different shapes of motor rotors, which can easily lead to unstable clamping.

[0026] 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.

[0027] like Figures 1 to 8 As shown, this utility model provides a fixing device for producing flat wire oil-cooled motor rotors, including a base 1. Mounting seats 11 are fixedly connected to both symmetrical sides of the top of the base 1. Two symmetrical sliding seats 2 are slidably connected to the surface of the base 1. A connecting plate 21 is fixedly installed on the top of each sliding seat 2. A slide rail 211 is fixedly connected to the surface of the connecting plate 21. A driving mechanism 3 is provided on the mounting seat 11 for driving the two sliding seats 2 to move towards each other on the surface of the base 1. A clamping block 4 is installed on the side of the two connecting plates 21 that is close to each other. A slider 41 is fixedly connected to the surface of the clamping block 4. The slider 41 is slidably connected to the slide rail 211. On both sides of the plate 21, there are mounting mechanisms 5 for assembling and disassembling the clamping block 4. The mounting mechanism 5 includes a slot 51 and an insert 52. The slide 211 and the slider 41 are both provided with slots 51. The slots 51 are slidably connected to the insert 52. A spring telescopic rod 53 is fixedly connected to the side of the insert 52 away from the slide 211. A fixing plate 54 is fixedly connected to the end of the spring telescopic rod 53 away from the insert 52. The fixing plate 54 is fixedly connected to the connecting plate 21. An adjusting plate 55 is fixedly connected to the end of the insert 52 away from the slot 51. Slide grooves 212 are provided on both sides of the connecting plate 21. The adjusting plate 55 slides in the slide grooves 212.

[0028] The above scheme is adopted as follows: In use, the clamping block 4 is replaced by the installation mechanism 5 according to the different shapes of motor rotors. The clamping block 4 that matches the shape of the motor rotor is used for clamping and fixing, making the fixation more stable. The adjusting plate 55 is moved manually along the slide groove 212 away from the slider 41, which drives the insert 52 to slide out of the slider 41 in the slot 51, making it easy to take out the clamping block 4 for replacement. At this time, the spring telescopic rod 53 is in a compressed state. After the replacement is completed, the adjusting plate 55 is released. At this time, the spring telescopic rod 53 is reset by its own elastic force, which drives the insert 52 to slide into the slider 41 along the slot 51. Inserting blocks 52 are provided on both sides, which can fix the slider 41 and thus complete the replacement and installation of the clamping block 4.

[0029] like Figures 1 to 8As shown, limiting components 56 for limiting the adjustment plate 55 are provided on both symmetrical sides of the connecting plate 21 near the slide groove 212. A limiting groove 551 is opened at the end of the adjustment plate 55 away from the insert block 52. The limiting component 56 includes a limiting insert plate 561, which is fixedly connected to the connecting plate 21. The limiting insert plate 561 slides through the limiting groove 551 and slides inside the limiting groove 551. A limiting block 562 is rotatably connected to the side of the limiting insert plate 561 near the adjustment plate 55. The shape and size of the limiting block 562 are the same as those of the limiting insert plate 561.

[0030] The above solution is adopted: By using the limiting component 56, in order to free up the hands during the replacement process, the adjusting plate 55 is limited. This can be achieved by moving the adjusting plate 55 towards the limiting insert plate 561, so that the limiting insert plate 561 passes through the limiting groove 551. At this time, the limiting block 562 and the limiting insert plate 561 are located on both sides of the limiting groove 551. By rotating the limiting block 562, it is made perpendicular to the limiting insert plate 561, thereby achieving the limitation and fixation of the adjusting plate 55 and preventing the spring telescopic rod 53 from rebounding during the replacement process.

[0031] like Figures 1 to 4 As shown, the drive mechanism 3 includes a screw 31, which is screwed to two sliding seats 2. Both ends of the screw 31 are rotatably connected to the mounting base 11. One end of the screw 31 passes through the mounting base 11 and is fixedly connected to a control motor 33. The control motor 33 is fixedly connected to the mounting base 11. Guide rods 32 are fixedly connected to both sides of the mounting base 11. The guide rods 32 are slidably connected to the sliding seats 2. A sleeve rod is fixedly connected to the center of the screw 31. The threads of the screw 31 on both sides of the sleeve rod are opposite.

[0032] The above scheme is adopted: the drive mechanism 3 drives the screw 31 to rotate by the control motor 33. Since the screw 31 has opposite threads on both sides of the sleeve rod, it drives the two sliding seats 2 to move in opposite directions along the guide rod 32 and the base 1. This can drive the two connecting plates 21 and the clamping block 4 to move closer or further away from each other, thereby achieving the clamping and fixing of the motor rotor.

[0033] The working principle and usage process of this utility model are as follows: When using this utility model, first, replace the appropriate clamping block 4 with the mounting mechanism 5 according to the shape of the motor rotor to be fixed. Then, manually move the adjusting plate 55 along the slide groove 212 away from the slider 41, causing the insert block 52 to slide out of the slider 41 in the slot 51, making it easy to remove the clamping block 4 for replacement. At this time, the spring telescopic rod 53 is in a compressed state. During the replacement process, the limiting component 56 limits the adjusting plate 55. By placing the motor rotor to be installed on the support plate between the connecting plates 21, the driving mechanism 3 drives the two connecting plates 21 and the clamping block 4 to clamp and fix the motor rotor, thus completing the entire usage.
