Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a device for machining and positioning a positioning groove on a bearing outer ring. Background Art

[0002] As we all know, a bearing must be assembled into its corresponding bearing seat to operate. The bearing outer ring and the bearing seat are fixed together to achieve circumferential and axial positioning. Circumferential positioning is usually achieved by creating a pair of symmetrical locating grooves on the bearing outer ring. These grooves cooperate with adaptive structures in the bearing seat to prevent relative rotational displacement between the outer ring and the bearing seat. The machining quality of the locating grooves directly affects the quality of assembly with the bearing seat. Due to the high symmetry requirements of the locating grooves, the scrap rate of the bearing outer ring is high. Utility Model Content

DETAILED DESCRIPTION

[0015] The utility model is described in detail according to the accompanying drawings.

[0016] like Figure 1 、 Figure 2 As shown, the bearing outer ring positioning groove processing positioning device includes a table 2, and the angle between the upper surface of the table 2 and the horizontal plane is 45 degrees.

[0017] A pendulum block locating seat 12 is fixed to the center of the upper portion of the tabletop 2. This locating seat 12 is connected to the pendulum block 11 via a rotating shaft 13. Two positioning posts 8 are located on the left and right sides of the lower portion of the tabletop 2, symmetrically distributed horizontally on the left and right sides of the pendulum block 11. A tool alignment groove 14 is provided on the lower edge of the tabletop 2, corresponding to the pendulum block 11.

[0018] In this embodiment, the vertical plates 1 are fixed to both sides of the back of the table 2 using positioning screws 9. A connecting plate 5 is fixed between the lower ends of the two vertical plates 1 using screws 6. The connecting plate 5 is provided with a positioning pin 7. The pendulum block positioning seat 12 is a U-shaped seat with a stud 4 at the bottom. The table 2 is provided with a through hole corresponding to the stud 4. The lower end of the stud 4 passes through the through hole and connects to the locking nut 3. The rotating shaft 13 on the pendulum block positioning seat 12 is parallel to the horizontal plane, and the positioning post 9 is perpendicular to the upper surface of the table 2. The rotating shaft 13 is a positioning bolt pair.

At this point, the tool-setting groove 14 is aligned with the machining position of the next positioning groove 1001 to be machined. The bottom slope of the machined positioning groove 1001 is 45 degrees.
