Description

Technical Field

[0001] The invention relates to the technical field of bearing component processing, in particular to a bearing component processing device. Background Art

[0002] The bearing seat is used to fix the outer ring of the bearing, so that the inner ring of the bearing can rotate stably, and the outer ring of the bearing remains stationary under the support of the bearing seat, always consistent with the direction of transmission. The conventional bearing seat consists of two parts, the upper part of the bearing seat is a ring structure, and the lower part is a rectangular seat. This structure makes it easy for the bearing seat to be installed in a suitable working position through its rectangular seat. The annular structure of the bearing seat is used to cooperate with the outer ring of the bearing, so the processing accuracy of the annular structure of the bearing seat directly affects its use effect.

[0003] During the existing processing of the bearing seat, it is locked on the positioning fixture, and the inner wall of the annular structure of the bearing seat is cut by controlling the rotation of the bearing seat and coordinating the movement of the cutting tool, and then the inner wall of the bearing seat is grinded by the grinding head. Although the above operation can lock the position of the bearing seat, due to the irregular structure of the bearing seat, it is easy to shake or jump when it rotates, which affects the processing effect of the inner wall of the annular structure of the bearing seat when cutting or grinding.

[0004] In addition, when locking bearing seats of different models, it is impossible to automatically lock the axis, so that the axis position of bearing seats of different models needs to be re-determined, and there is a deviation between the axis position of the bearing seat and the position of the cutting tool or the grinding head, which affects the processing accuracy of the bearing seat. In addition, the clamping operation of bearing seats of different models is more cumbersome. After the bearing seat is cut, the grinding head needs to be repositioned, which makes the grinding head have the hidden danger of position deviation. When the cutting tool or the grinding head processes the annular inner wall of the bearing seat, the cutting tool or the grinding head will shake due to its excessive extension length, further affecting the processing accuracy of the bearing seat.

A rotating ring 423 is arranged on the left side of the clamping support plate 41 and coaxially with the circular groove. An adjusting link 424 is hingedly connected to the left end of each clamping column 422 and the inner side of the rotating ring 423. The locking assembly 42 is used for Different types of bearing seats are clamped and locked in multiple directions, and the locking assembly 42 performs fixed-axis clamping on the annular structure of the bearing seat, so that the axial positions of different types of bearing seats are the same after being locked; specifically, when the bearing seat is placed on the right side of the clamping support plate 41, one end of the adjusting connecting rod 424 is driven to rotate synchronously by rotating the rotating ring 423, and the other end of the adjusting connecting rod 424 can synchronously drive the clamping columns 422 at different positions to slide in the sliding groove 421, so that the clamping columns 422 at different positions move inward or outward synchronously, so that the locking assembly 42 can clamp different types of bearing seats.

At this time, the clamping column 422 can be moved to the specified position, thereby completing the clamping and locking of the annular structure of the bearing seat. At this time, the pulling of the pulling column 427 is removed, and the blocking tooth 426 moves again between the adjusting teeth 425 at the corresponding position, so that the position of the rotating ring 423 is locked again.

The outer side of the right end of the upper clamping column 422 is an external thread structure, and the external thread structure of the upper clamping column 422 is connected to a clamping ring 43 by thread matching. The present invention uses the clamping ring 43 that matches the upper clamping column 422 to make the bearing seat tightly attached to the clamping support plate 41, thereby preventing the bearing seat from being displaced left and right during processing. Specifically, after the clamping column 422 completes the clamping of the annular structure of the bearing seat, the clamping ring 43 is tightened on the upper clamping column 422, so that the clamping of the annular structure of the bearing seat is more stable.

[0041] See also Figure 4 and Figure 6 , the two clamping columns 422 on the lower side are both rotatably sleeved with a shaft sleeve 44 on the outer side, a screw sleeve 45 is rotatably connected to the outer side of the shaft sleeve 44, and a clamping column 46 is rotatably connected to the end of the screw sleeve 45 away from the shaft sleeve 44; the present invention adjusts the position of the clamping column 46 through the screw sleeve 45 with adjustable length, thereby further increasing the stability and applicability of the bearing seat. Specifically, after the annular structure of the bearing seat is clamped, the shaft sleeve 44 is sleeved on the outer side of the two clamping columns 422 on the lower side, and the screw sleeve 45 connected to the outer side of the shaft sleeve 44 is rotated and adjusted, so that the clamping column 46 connected to the end of the screw sleeve 45 away from the shaft sleeve 44 is pressed against the intersection of the annular structure of the bearing seat and the rectangular seat, so that the stability of the bearing seat clamping is further increased.
