Device for pressing ball bearing into stator and operation method of device

Abstract

The invention discloses a device for pressing a ball bearing into a stator and an operation method of the device. The device is used for pressing the ball bearing into the stator, and the device comprises an upper die, an upper die holder, a lower die, a pressing block, a core rod, a bearing sleeve and an inner ball bearing; the lower die is provided with a stator mounting groove, the stator is placed in the stator mounting groove, and a bearing sleeve is arranged in the middle of the stator; the bearing sleeve is arranged outside the inner ball bearing in a sleeving mode and connected with anouter ring of the inner ball bearing; the upper die comprises a main body part and a shaft part, the shaft part penetrates through the main body part and is hollow; the shaft part comprises an upperend shaft and a lower end shaft at the two ends of the main body part, and the inner ball bearing is located outside the upper end shaft and connected with the upper end shaft. The pressing block is located on the top face of the inner ball bearing and connected with the top face of the upper end shaft, the upper die base is connected with the bearing sleeve, the core rod is located in the lower end shaft and connected with the lower end shaft, the free end of the core rod extends out of the lower end shaft, and the to-be-installed ball bearing is installed at the free end of the core rod. Andglue is prevented from overflowing to the end face of the ball bearing to be mounted in the manual gluing operation process.

Description

technical field [0001] The invention relates to the technical field of motor assembly, in particular to a device for pressing a ball bearing into a stator and an operation method thereof. Background technique [0002] The ball bearings used in micro motors are small in size and limited by the shape of the ball bearings, so the inner and outer rings are designed to be very thin. The interference fit between the motor case and the ball bearings cannot be used, and the outer ring will appear in the interference fit. Deformation caused by force causes noise or jamming of the ball bearing, so it can only be fixed with loose fit design and glue. In the existing production process, glue is generally used on the outer surface of the ball bearing by hand, and then loaded into the stator bearing hole. The operation process is difficult and the production efficiency is low. During the operation process, it is easy to overflow the glue to the end surface of the ball bearing and cause th...

Problems solved by technology

[0003] In order to solve the problems in the prior art, the present invention provides a ball bearing pressing into the stator device, which solves the problem that the glue overflows to the end surface of the ball bearing and causes the ball bearing to stick to death during the existing operation process.
