[0002] Since the skeleton sealing ring is composed of rubber inside and a steel ring, it is soft and has a certain hardness, especially the outer circle is large in size and small in thickness. It is difficult to make it concentric with the installation hole during manual installation. Once it is not concentric, the skeleton After the sealing ring is pressed in, its end face is not parallel to the axis of the installation hole
Due to the small margin in the installation position of the motor skeleton sealing ring, it is easy to cause friction with other parts, causing the temperature of the motor to rise rapidly

Embodiment Construction
[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0012] Such as figure 1 As shown, the motor frame sealing ring press-in device includes a hydraulic press, an upper tire 1, a lower tire 2 and a bottom tire 3, the bottom tire 3 is fixed on the hydraulic press workbench 7, and the lower tire 2 is stacked on the bottom tire 3 , the upper tire 1 is fixed with the hydraulic press main shaft 6.
[0013] Such as figure 2 As shown, the upper tire 1 is a cylinder, and the bottom surface of the cylinder is concentric with the center of the bottom surface to form two-stage convex posts. The first-stage convex posts form a skeleton sealing ring sleeve column 1-1, and the surface of the first-stage convex posts forms a positioning platform 1- 3. The second-stage boss forms an insertion shaft 1-2 on the positioning platform 1-3.
[0014] Such as image 3 As shown, the lower tire 2 becomes cylindrical, and the ...

In order to solve the technical problem that a framework sealing ring is difficultly concentric with an installation hole when pressed in a motor at present, the invention provides a device for pressing the framework sealing ring in the motor. The device comprises an oil press, an upper tire, a lower tire and a bottom tire, wherein the bottom tire is fixed on a workbench of the oil press; the lower tire is stacked above the bottom tire; the upper tire is fixed with a spindle of the oil press; the framework sealing ring is sleeved on the upper tire; a bearing outer cover is arranged on the lower tire; and the framework sealing ring is pressed in the bearing outer cover when the oil press works. The device has a simple structure, is convenient to operate, is simply and flexibly replaced, and effectively avoids the phenomena of non-concentricity and deformation when the framework sealing ring is pressed in the motor.
Description
technical field [0001] The invention relates to a pressing-in device for a motor frame sealing ring. Background technique [0002] Since the skeleton sealing ring is composed of rubber inner and steel ring, it is soft and has a certain hardness, especially the outer circle is large in size and small in thickness. It is difficult to make it concentric with the installation hole during manual installation. Once it is not concentric, the skeleton After the sealing ring is pressed in, its end face is not parallel to the axis of the mounting hole. Due to the small margin in the installation position of the motor frame sealing ring, it is very easy to cause friction with other parts, causing the temperature of the motor to rise rapidly. Contents of the invention [0003] In order to overcome the current technical problem that the seal ring and the mounting hole are difficult to be concentric when the motor skeleton seal ring is pressed in, the invention provides a motor skeleto...
