Description

Bearing steel ball dismounting device

Technical Field

The utility model relates to a bearing processing technology field, concretely relates to bearing steel ball's dismouting device.

Background

The assembly of the ball by the bearing is an important process link for the assembly of the rolling bearing, namely, the inner ring and the outer ring of the rolling bearing are sleeved, the steel ball is uniformly arranged in the interval between the inner ring and the outer ring, and then the outer ring is extruded to generate a tiny deformation, so that the steel ball rolls into the roller paths which are oppositely arranged on the inner ring and the outer ring, and then the steel ball is arranged in a bearing retainer; and the steel ball is disassembled only by disassembling the bearing retainer, pulling the steel ball flat, pressing the outer ring to deform the outer ring, and picking out the steel ball. Whole process all relies on staff's manual, and the size and the angle that exert force are different when carrying out extrusion operation to outer lane for the workman that is more hard and different, and the very easy misoperation of unskilled workman to lead to the steel ball to receive the extrusion with interior outer lane, cause the damage.

SUMMERY OF THE UTILITY MODEL

To current manual suit ball to the bearing, hard and make the impaired shortcoming of bearing easily, the utility model provides a dismouting device of bearing steel ball, the device is laborsaving and can avoid the bearing impaired.

The utility model provides a following technical scheme:

the utility model provides a dismouting device of bearing steel ball which characterized in that: the die core comprises a die core seat, wherein an inner ring barrier strip is arranged on the die core seat, a limiting column is pressed on the side surface of one side of the die core seat, one end of a push rod points to the die core seat, the other end of the push rod penetrates through a guide hole and is pressed on the outer edge of a cam, the rotating center of the cam is fixedly arranged on a rotating shaft, two ends of the rotating shaft are respectively rotatably arranged on a support, and one end of the rotating shaft is provided with a handle; the guide hole is arranged on the bracket.

It is further characterized in that:

a limiting groove is formed in the outer side of the guide hole, a limiting plate is arranged on the outer side of the push rod, and the limiting plate is slidably mounted in the limiting groove;

and a spring is pressed between the limiting plate and the side wall of the limiting groove.

Compared with the prior art, the beneficial effects of the utility model are as follows:

in the figure: 1, a die core seat; 11, inner ring barrier strips; 2, a limiting column; 3, pushing a rod; 31 a limiting plate; 4, guiding holes; 5, a cam; 6 a rotating shaft; 7, a bracket; 8, a handle; 9, limiting grooves; 10 spring.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a bearing steel ball dismounting device comprises a die core holder 1, wherein an inner ring barrier 11 is arranged on the die core holder 1, a limiting column 2 is pressed on one side surface of the die core holder 1, the other side of the die core holder 1 is provided with a push rod 3, one end of the push rod points to the die core holder 1, the other end of the push rod passes through a guide hole 4 and is pressed on the outer edge of a cam 5, the rotating center of the cam 5 is fixedly arranged on a rotating shaft 6, two ends of the rotating shaft 6 are respectively rotatably arranged on a support 7, and one end of the; the guide hole 4 is provided in the bracket 7. The utility model discloses a rotatory handle 8 drives cam 5 and rotates, and 5 outer fringe of cam promotes push rod 3 and presses in placing the bearing inner race on die core seat 1, and the bearing inner race atress is even, and is easy and simple to handle, therefore the device is laborsaving and can avoid the bearing impaired.

Limiting groove 9 is seted up in the guiding hole 4 outside, and the 3 outsides of push rod are provided with limiting plate 31, and limiting plate 31 slidable mounting has spring 10 in limiting groove 9, pressure between limiting plate 31 and the 9 lateral walls of limiting groove. The limiting groove 9 ensures the moving distance of the push rod 3, and the elasticity of the spring 10 ensures that the push rod 3 can automatically return to the original position after being pressed, thereby further simplifying the operation and saving labor.
