Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, specifically a motor stator clamping and fixing device. Background Technology

[0002] The motor stator is one of the core components of a motor. During stator production, various accessories, such as insulating slot wedges, end binding pieces, terminals, or temperature sensors, need to be pressed or installed onto the stator core or windings. The installation accuracy and clamping force of these accessories directly affect the motor's insulation performance, heat dissipation, and operational reliability. With the increasing automation in motor manufacturing, higher demands are placed on the efficiency, consistency, and flexible changeover capabilities of stator accessory pressing.

[0003] Currently, the pressing of motor stator components mostly employs a single-station press combined with manual feeding. Operators place the stator on the press fixture, manually place the components, start the press to complete the pressing, and then remove the finished product. This method has the following drawbacks: First, single-station sequential operation requires loading, unloading, and pressing to be performed serially, resulting in low production efficiency and difficulty in meeting the needs of mass production; second, the stator needs to be moved and re-clamped multiple times between different processes, easily causing accumulated positioning errors and affecting pressing accuracy; third, different fixtures and jigs need to be changed for different stator and component models, making changeover adjustments cumbersome and reducing equipment flexibility; fourth, the consistency of manually placed components is difficult to guarantee, easily leading to skewing or misalignment, resulting in poor pressing or stator damage.

[0004] Therefore, there is an urgent need for a clamping and fixing device that can achieve multi-station continuous pressing, automatic stator repositioning, precise alignment of accessories, and quick adaptation to stators and accessories of different specifications, so as to improve the efficiency and quality of motor stator assembly.

[0043] The workflow of this invention is as follows: The working process of the motor stator clamping and fixing device can be divided into six stages: stator clamping, accessory clamping, press-fit alignment, press-in operation, station switching and continuous production, and finished product unloading. The actions of the components involved in each stage are detailed below.

[0044] I. Stator clamping stage The motor stator of the component to be installed is placed into the rotating sleeve 303 of the stator fixing mechanism 3 corresponding to the press-fitting station. The first linear motor 309 of this station is started, and the first linear motors 309 on both sides extend synchronously, pushing the arc-shaped clamping plate 310 to move towards the center, clamping the stator from the outer circle. The baffle 311 at the bottom of the arc-shaped clamping plate 310 axially limits the end face of the stator, completing the stator fixing.

[0045] II. Parts Clamping Stage According to the specifications of the component to be pressed, select the appropriate position and number of elastic ferrule mechanisms 7, insert their insertion rods 702 into the corresponding vertical through holes 603 on the lifting disc 602, and screw in the locking bolts 703 from below to secure them. Place the component to be pressed onto the elastic ferrule mechanism 7: pull the pull plate 708 outward, stretch the tension spring 707, and the pull rod 709 drives the side clamping plate 710 and the wedge block 711 to move outward, placing the component between the top ring 705 and the side clamping plate 710. Release the pull plate 708, the tension spring 707 pulls back, the wedge block 711 engages with the side wall hole of the sliding sleeve 706 to achieve one-way self-locking, and the side clamping plate 710 clamps the component laterally. The compression spring 704 applies a downward elastic preload to the component through the top ring 705, ensuring that the component is reliably clamped.

[0046] II. Press-fitting and alignment stage The second motor 502 of the displacement adjustment mechanism 5 starts, driving the threaded rod 503 to rotate. The adjusting block 504 drives the lifting plate mechanism 6 and the elastic sleeve mechanism 7 to move laterally, so that the accessories on the elastic sleeve mechanism 7 are moved directly below the pressure plate 1003 of the feeding and pressing mechanism 10. The second linear motor 601 starts, adjusting the height of the lifting disc 602 so that the accessories are at the appropriate pressing height.

[0047] The first motor 202 of the rotating mounting plate mechanism 2 starts and drives the rotating disc 204 to revolve around the horizontal axis through the first rotating shaft 203, rotating the stator fixing mechanism 3 containing the stator to the pressing position, so that the stator is located between the pressure plate 1003 and the accessory.

[0048] The third motor 802 of the rotary drive mechanism 8 starts, and the drive shaft 803 rotates. The power is output in two paths: one path drives the third rotating shaft 401 of the fixed linkage mechanism 4 to rotate through the engagement of the fourth bevel gear 804 with the third bevel gear 403. The second gear 402 on the third rotating shaft 401 drives the first gear 306 to rotate, and through the transmission of the second rotating shaft 305, the first bevel gear 307 and the second bevel gear 308, it drives the rotating sleeve 303 and the stator to rotate around their own axis. The other path drives the drive sleeve 902 to rotate through the cooperation of the drive groove 805 and the drive bar. Through the transmission of the fifth bevel gear 903, the sixth bevel gear 904, the fourth rotating shaft 905, the seventh bevel gear 906 and the eighth bevel gear 907, it drives the second linear motor 601 and the lifting disc 602 to rotate around the vertical axis. The rotation of the stator cooperates with the rotation of the accessories on the elastic ferrule mechanism 7 to ensure that the accessories are precisely aligned with the installation positions on the stator.

[0049] IV. Pressing Operation Stage The pneumatic telescopic rod 1002 of the feed clamping mechanism 10 is activated, driving the pressure plate 1003 to move downward. The pressure plate 1003 presses down on the accessory on the elastic sleeve mechanism 7, overcoming the elastic force of the clamping spring 704, and presses the accessory into the corresponding installation position on the lower stator. After being pressed into place, the pneumatic telescopic rod 1002 retracts, and the pressure plate 1003 rises to reset.

[0050] V. Workstation Switching and Continuous Production Stage After the current pressing station is completed, the first motor 202 drives the rotating disk 204 to revolve again, moving the pressed stator out of the pressing station. At the same time, the stator fixing mechanism 3, which contains the next stator to be pressed, rotates to the pressing station. While the pressing operation is being performed at the pressing station, the operator can perform stator clamping, accessory placement, or finished product unloading operations at other stations, realizing multi-station parallel operation and improving production efficiency.

[0051] VI. Finished Product Cutting Stage After the press-fitted stator revolves with the rotating disk 204 to the unloading station, the first linear motor 309 of the corresponding stator fixing mechanism 3 retracts in the opposite direction, and the arc-shaped clamping plate 310 releases the stator. The finished stator is then removed from the rotating sleeve 303. The freed-up stator fixing mechanism 3 can then clamp new stators to be press-fitted, entering the next work cycle.
