Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically to a pressing device for motor stator. Background Technology

[0002] The stator is an important component of motors such as generators and starters. It consists of three parts: the stator core, stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force within this rotating magnetic field, thereby generating (outputting) current. Currently, when pressing the stator into the iron housing of a brushless DC motor, a stator pressing device is required.

[0003] Existing motor stator pressing devices suffer from several drawbacks. Firstly, the stator is not properly positioned before pressing, leading to uneven pressing, uneven force distribution, damage to the winding coil, and poor dimensional consistency. This results in product quality and operational safety risks. Secondly, the device cannot quickly reset the structure or remove the stator after pressing, resulting in low efficiency, inconvenient operation, and poor applicability. Utility Model Content

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1-5As shown, this utility model provides a pressing device for a motor stator, including a support plate 1, a control box 3, and a pressing mechanism 4. A fixing frame 2 and a fixing plate 6 are fixedly installed on the top of the support plate 1. The control box 3 is fixedly installed on the top of the fixing frame 2. The pressing mechanism 4 is located at the bottom of the control box 3, and a pressing mold 5 is provided at one end. A support assembly 8 is provided on the top of the fixing plate 6. The support assembly 8 includes a fixing seat 801, and a positioning mechanism 9 is provided on the top of the fixing seat 801. The positioning mechanism 9 includes a socket 903, several buffer springs 905, a pressing block 909, and a second buffer spring 900. When the socket 903 and the pressing block 909 move vertically downwards, they respectively press the first buffer spring 905 and the second buffer spring 900. Two positioning rods 910 and a foolproof block 914 are fixedly installed on the top of the socket 903, and a foolproof rib 911 is fixedly installed on the inner wall. The positioning mechanism 9 also includes a support seat 901, and a lower mold base 906 is fixedly installed on the top of the support seat 901. The top of the positioning mechanism 9 is provided with a groove 913, and the anti-fooling rib 911 slides in cooperation with the groove 913. The positioning mechanism 9 also includes several fixing rods 902, which are all fixedly installed on the top of the bearing seat 901. The sleeve seat 903 is slidably sleeved on the fixing rods 902, and one end of the sleeve seat 903 is threaded with a limit nut 904. The buffer spring 905 is sleeved on the fixing rods 902, and one end is connected to the top of the bearing seat 901. The positioning mechanism 9 also includes a centering block. 907, the centering block 907 is fixedly installed inside the lower mold base 906, the top of the centering block 907 is provided with a fixing rod 908, the fixing rod 908 slides with the centering block 907 and the lower mold base 906, the extrusion block 909 is fixedly installed at one end of the fixing rod 908, the buffer spring 900 is sleeved on the fixing rod 908, and its two ends are respectively connected to the centering block 907 and the extrusion block 909. The pressing mechanism 4 includes a presser 401, a connecting piece 403 and a pressing cylinder 402.

[0024] The operator first places the stator onto the anti-fooling rib 911, and then inserts it onto the two positioning rods 910, so that the positioning rods 910 and the anti-fooling rib 911 can position the stator. Then, the stator after positioning is locked onto the socket 903. After the stator is fixed, the press-in machine 401 is started. After the press-in machine 401 operates, it can push the connector 403 and the lower pressing cylinder 402 vertically downward. When the lower pressing cylinder 402 moves, it pushes the lower pressing mold 5 to move through the chuck 506 and the disc 505, so that the lower pressing mold 5 cooperates with the lower mold base 906 after moving a certain distance and squeezes the stator. By positioning the stator, the accuracy of the stator during pressing can be effectively improved, and the production quality of the stator can be improved.

[0025] During stator extrusion, the stator can push the extrusion block 909 and the socket 903 to move under the extrusion force. When the extrusion block 909 is pushed, it can drive the fixed rod 908 to slide and compress the buffer spring 900. When the socket 903 moves, it compresses several buffer springs 905. When the stator extrusion is completed and the press machine 401 is closed, several buffer springs 905 and buffer spring 900 release pressure, so that the socket 903 and the extrusion block 909 return to their initial positions, which is convenient for the next work. It also allows the stator to move vertically upward a certain distance, which is convenient for the staff to take out the stator. It can effectively improve work efficiency and has strong applicability.

[0026] like Figure 2 As shown, in one embodiment, the support assembly 8 further includes two fixing blocks 802, which are fixedly installed on the top of the fixing base 801. Guide rods 803 are fixedly installed on the top of the fixing blocks 802. The pressing mold 5 is slidably sleeved on the two guide rods 803. The pressing machine 401 is fixedly installed at the bottom of the control box 3. The two ends of the connector 403 are fixedly connected to the output end of the pressing machine 401 and the top of the pressing cylinder 402, respectively. The bottom of the pressing cylinder 402 abuts against the top of the chuck 506.

[0027] The guide rod 803 can limit the movement of the lower die 5, improving the accuracy of the movement of the lower die 5.

[0028] like Figure 4-5 As shown, in one embodiment, a limiting fixture 503 is fixedly installed on the top of the pressing mold 5. A docking groove 504 is provided at the bottom of the limiting fixture 503. A disc 505 is provided in the docking groove 504. A chuck 506 is fixedly installed on the top of the disc 505. A fixing post 507 is fixedly installed on the top of the chuck 506.

[0029] The chuck 506 and disc 505 can be removed at any time by horizontal sliding, making them easy to replace, reducing maintenance difficulty, and making them highly versatile.

[0030] The working principle of the stator pressing device for this motor will be explained in detail below:

[0031] The operator first places the stator onto the anti-fooling rib 911, and then inserts it onto the two positioning rods 910, so that the positioning rods 910 and the anti-fooling rib 911 can position the stator. Then, the stator after positioning is locked onto the socket 903. After the stator is fixed, the press-fit machine 401 is started. After the press-fit machine 401 is running, it can push the connector 403 and the lower pressing cylinder 402 vertically downward. When the lower pressing cylinder 402 moves, it pushes the lower pressing mold 5 to move through the chuck 506 and the disc 505, so that the lower pressing mold 5 cooperates with the lower mold base 906 after moving a certain distance and squeezes the stator.

[0032] During stator extrusion, the stator can push the extrusion block 909 and the socket 903 to move under the extrusion force. When the extrusion block 909 is pushed, it can drive the fixed rod 908 to slide and compress the buffer spring 900. When the socket 903 moves, it compresses several buffer springs 905. When the stator extrusion is completed and the press machine 401 is closed, several buffer springs 905 and buffer spring 900 release pressure, so that the socket 903 and the extrusion block 909 return to their initial positions, which is convenient for the next work. It also allows the stator to move vertically upward a certain distance, which is convenient for the staff to take out the stator. It can effectively improve work efficiency and has strong applicability.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
