Description

Technical Field

[0001] The invention belongs to the technical field of electrical machinery, and in particular relates to a large-scale variable frequency motor iron core pressing device. Background Art

[0002] In the past, in the field of motor stator production, the stator clamping method of variable frequency motors was an external independent clamping mechanism. With the breakthrough of variable frequency motor technology, the size of motors has continued to increase, and the required clamping force has also increased accordingly. Continuing to use an external independent clamping mechanism will make the equipment too large, resulting in reduced equipment efficiency and a significant increase in manufacturing costs. Summary of the invention

[0003] In order to overcome the above technical deficiencies, the present invention provides a large-scale variable frequency motor core clamping device.

[0004] The technical solution adopted by the present invention is: a large-scale variable frequency motor iron core clamping device, characterized in that: the guide sleeve is fixedly connected to the support plate by screws, the guide column is slidably connected to the guide sleeve and is fixedly connected to the clamping inner ring by screws, the positioning seat equipped with the iron core is fixedly connected to the clamping inner ring, a reset spring is provided between the clamping inner ring and the support plate, the reset spring is installed on the outside of the guide sleeve, the driving plate equipped with the roller assembly is installed on the clamping outer ring, the roller assembly is composed of a pressure wheel and a wheel axle supported by the roller seat, the clamping inner ring can rotate with the clamping outer ring through a steel ball, the clamping outer ring is fixedly connected to the clamping guide plate by a connecting rod, and the clamping drive plate is installed in the clamping guide plate groove The cam is provided with an air filter which is fixed to the base through a fixing member and the guide seat is provided with a locking member, the guide seat is provided with a locking member, the support plate is provided with an air filter which is fixed to the base through a fixing member, the guide seat is provided with a locking member, the support plate is provided with an air filter which is fixed to the base through a fixing member, the guide plate ...

[0005] Due to the adoption of the above technical solution, after the iron core is installed in the positioning seat, the positioning cylinder pushes the locking block to slide in the guide seat and insert it into the driving handle groove, and the driving disk is fixed. At this time, the driving wheel drives the outer ring to rotate, and the needle roller and the outer bushing installed on the limit block move along the outer ring slide track, extending the limit block to block the right side of the iron core. The clamping cylinder drives the hinge to rotate the clamping drive disk. There is a sloped boss on the tight drive disk. As the tight drive disk rotates, the roller is squeezed, so that the pressure plate fixed to the roller squeezes the clamping outer ring. The positioning seat installed with the iron core is installed on the clamping inner ring, and the clamping inner ring is connected to the clamping outer ring through the steel ball. Therefore, the pressure plate squeezes the clamping outer ring to drive the iron core to move axially and finally contact the limit block to realize the clamping function. The device has the characteristics of simple and compact structure, low production cost, strong clamping force, etc. It is particularly suitable for the production of large-scale variable frequency motor products and greatly improves production efficiency.

[0006] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
