Description
PERPENDICULARITY MEASURING DEVICE FOR THE INNER DIAMETER OF BEARING RINGS
Technical Field
The invention is related to a bearing ring inner diameter perpendicularity measuring assembly.
Prior Art
The inner diameter perpendicularity parameter of bearing rings is measured in the measurement laboratory during the turning operation. The measurement results take a long time. Manufacturing cannot be made until the measurement result is obtained from the measurement laboratory. There is a risk that the parts manufactured without obtaining the measurement results will be unsuitable and defective. This causes the manufacture of scrap rings.
Since the perpendicularity parameter of the bearing ring inner diameter cannot be measured on the turning lathe, valuable time is lost.
Therefore, various improvements have been made in the art in order to measure the inner diameter perpendicularity of the bearing rings on the turning lathe.
A device measuring the ring inner diameter perpendicularity is mentioned in the document number CN2076669 in the present state of the art. The fixed abutment end point and the movable measuring end points are located on different planes.
In the patent document number CN104296618A in the present state of the art, a device which is used to measure the bearing clearance from the outer diameter by taking the inner diameter of the bearing as a reference is mentioned.
In the patent document number CN101852604A in the present state of the art, a device which is used to measure the perpendicularity of the outer diameter of a bearing by taking the outer diameter as reference is mentioned.
When the perpendicularity parameter measurement techniques of the bearing ring inner diameter in the present state of the art were examined, it was determined that perpendicularity measurement cannot be made with the desired precision and accuracy due to the fact that the fixed end and the moving ends used in the measurements are not on the same plane and they are referenced from different surfaces of the bearing ring. Therefore, there is a need for developing a measuring assembly in which the fixed end and the moving ends are on the same plane and the inner surface of the bearing ring itself is taken as reference when measuring.
Purposes and Brief Description of the Invention
The object of the present invention is realizing an assembly for measuring the inner diameter perpendicularity parameter on the turning lathe during bearing ring turning operation.
Another object of the present invention is to realize an assembly in which fixed and moving ends can be measured on the same plane and the inner surface of the bearing ring itself is taken as reference.
The inventive inner diameter perpendicularity measuring assembly comprises a measuring plate, a fixed abutment end, and a movable abutment end. The fixed and movable abutment ends contact the bearing ring on the same plane from the inner diameter of the ring. After the fixed abutment end is fixed at any point on the bearing inner surface, the movable abutment end is contacted at a different point on the bearing inner surface. If there is a perpendicularity difference between the contact point of the fixed abutment end and the contact point of the movable abutment end, the movable abutment end moves on the horizontal axis as far as this perpendicularity difference. This movement is measured with the spring system to which the movable abutment end is connected, and transmitted to the comparator, thereby measuring the perpendicularity difference between the two points.

13. Bearing ring
The bearing ring inner diameter perpendicularity measuring device (1), which is the subject of the invention, comprises:
A measuring plate (2) on which a bearing ring (13) is placed,
A movement channel (3) that extends from one corner of the measuring plate (2) to the other comer,
A centering abutment end (4) that can move within the channel (3),
A fixed abutment end (5) that extends from the bottom of the measuring plate (2) to the top through the channel (3) and contacts the inner surface of the bearing ring (13), A movable abutment end (6) that extends from the bottom of the measuring plate (2) to the top through the channel (3) and contacts the inner surface of the bearing ring (13) on the same plane as the fixed abutment end (5),
A fixed abutment end connecting apparatus (7) to which the fixed abutment end (5) is connected,
A movable abutment end connecting apparatus (8) to which the movable abutment end (6) is connected,
A spring system (9) connected to the movable abutment end connecting apparatus (8),
A contact shaft (10) connected to the spring system (9),
A comparator (11) connected to the contact shaft (10),
A retainer (12) securing the comparator (11) to the measuring plate (2).
The perpendicularity measurement assembly (1), which is the subject of the invention, has a rectangular measuring plate (2). There is a centering abutment end movement channel (3) that extends through the middle of the measuring plate (2). There is a centering abutment end (4) that can move within the channel (3). The centering abutment end (4) moves within the centering abutment end movement channel (3) and is fixed by contacting the inner diameter of the bearing ring (13). The bearing ring (13) is thus centered. (Figure 1 and Figure 2)
There is a fixed abutment end connecting apparatus (7) on the lower surface of the measuring plate (2). The fixed abutment end connecting apparatus (7) has a fixed abutment end (5) that extends towards the upper surface of the measuring plate (2). The fixed abutment end (5) is positioned with the help of the fixed abutment end connecting apparatus (7) in an upward- downward movement so that it contacts the inner diameter of the bearing ring (13) from the point (B). (Figure 2 and Figure 3)
There is a movable abutment end connecting apparatus (8) next to the fixed abutment end connecting apparatus (7). The movable abutment end connecting apparatus (8) has a movable abutment end (6) that extends towards the upper surface of the measuring plate (2). The
movable abutment end (6) is located above the fixed abutment end (5). The movable abutment end (6) is positioned with the help of the movable abutment end connecting apparatus (8) in an upward-downward movement so that it contacts the inner diameter of the bearing ring (13) from the point (C). (Figure 2 and Figure 3)
If there is a perpendicularity difference (e.g., X) between the contact point (B) of the fixed abutment end (5) and the contact point (C) of the movable abutment end (6), the movable abutment end (6) moves on the horizontal axis (X) as far as this perpendicularity difference (X). (Figure 4)
There is a spring system (9) under the fixed abutment end connecting apparatus (7) and the movable abutment end connecting apparatus (8). The movement of the movable abutment end (6) in the amount of the distance (X) between the point (B) and the point (C) moves the spring system (9). The spring system (9) transmits this movement to the contact shaft (10). In turn, the contact shaft (10) transfers this movement to the comparator (11) fixed by the comparator retainer (12). Thus, perpendicularity measurement is completed in the comparator (11). (Figure 2 and Figure 4)
