Problems solved by technology
[0003] However, because the shell of the VLB and VLBL series flameproof vibration motors and the stator core with windings are assembled by press-fitting, the stator core with windings will inevitably tilt when placed during the assembly process, and the The pressure of the hydraulic press acts directly on the winding stator core through the hydraulic press block and the special press-in die, resulting in damage to the winding stator core during the press-fitting process
The scrap rate of wound stator core due to press-fit assembly is as high as 30%-50%

Embodiment Construction
[0039] The present invention implements press-fit assembly by adding a guide sleeve. The method is: add a guide sleeve between the press-in part and the pressed-in part, and use the guide sleeve to make the center line of the press-in part and the center of the press-in part The lines are consistent; during the press-in assembly process, the hydraulic press block presses the press-in parts through the press-in die, and the guide sleeve guides the press-in parts; in this way, the press-in parts and the pressed-in parts are realized. Press fit.
[0040] The present invention will be further described below in conjunction with example and accompanying drawing.
[0041] The present invention provides the application method of the guide sleeve in the press-fit assembly of the long tube parts. The method uses the guide sleeve 6 to constrain the lateral degree of freedom of the winding stator core 4 . In the process of press-fitting the winding stator core 4 and the long rod motor h...

The invention provides an application method for a guide sleeve in long-barrel part press-in assembling, which is a vertical press-in assembling method for improving the guide of the guide sleeve. The application method specifically comprises the steps of: restraining the lateral degree of freedom of a press-in part by the guide sleeve; preventing the center line of the press-in part and the center line of a pressed-in part from inclining so as to perform a guide action on the press-in part; and in the press-in assembling process, pressure is vertically acted on the press-in part of which the lateral degree of freedom is restricted by the guide sleeve via a press-in die by a hydraulic press block so as to realize the press-in assembling of the press-in part. According to the method, the operation is convenient and the master is easy. The application method comprises the specific steps of installing, press fitting and detecting. Because the application method for the guide sleeve in long-barrel part press-in assembling adopts a press fitting method that the lateral degree of freedom of a press-in part is restrained by the guide sleeve to guide, the product percent of pass in the press-in assembling process is effectively improved, and the assembling quality is guaranteed.
Description
technical field [0001] The invention relates to the field of press-fit assembly of long tube parts, especially the place where the center line of the press-in part tends to be inclined relative to the center line of the part being pressed in during the placement process. Background technique [0002] Press-fit assembly is currently used in a wide range of applications in many products. For example, the VLB and VLBL series explosion-proof vibration motors produced by Zhongxiang Xinyu Electromechanical Manufacturing Co., Ltd., the connection between the shell and the winding stator core belongs to pressure assembly. This series of explosion-proof vibration motors is a kind of slender structure vibration motor (hereinafter referred to as the long rod motor), and the distance between the point of action of the exciting force (the distance between the anchor holes) is very wide. Especially practical. This kind of vibrating motor is equipped on the vibrating machine, which can m...
