Description

Technical Field

[0001] The utility model relates to the technical field of retainer processing, in particular to a cutting device for processing a solid retainer. Background Art

[0002] A cage (i.e., a bearing cage, also known as a bearing retainer) refers to a bearing part that partially wraps all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually guide the rolling elements and retain them in the bearing. When the cage is processed, a cutting machine is used to cut the cage blank. This cutting device is used to cut the cage blank.

[0003] When processing the retainer, the blank needs to be cut. During the cutting process, the positions of the cutting nodes of the blank are different. The cutting nodes are sometimes close to the left end of the blank and sometimes close to the right end of the blank. On ordinary cutting devices, the clamps used will lock and limit the blank, and the lateral movement of the blank cannot be adjusted, resulting in poor flexibility during the cutting process of the blank.

[0011] Preferably, the cross plate is fixedly connected to both the pressure rod and the side seat, and the side seats are symmetrically distributed about the center of the cross plate, and the side seats and the screw bar are threadedly connected.

[0012] The utility model has at least the following beneficial effects:

[0013] 1. By rotating the screw rod, the transmission slider is driven, so that the slider displaces along the length direction of the screw rod, changing the positions of the slider and the auxiliary seat. After the auxiliary seat moves laterally, it drives the blank of the cage placed and clamped at the lateral end of the auxiliary seat to displace, changing the position of the cutting point of the blank, and conveniently and flexibly adapting to the processing and segmentation requirements of the blank. The motor on the top of the auxiliary seat runs to drive the screw rod to rotate, and the screw rod drives the sliding seat to displace along the length direction of the screw rod, changing the positions of the sliding seat and the abutment seat. After the abutment seat moves upward, it drives the blank of the cage clamped and limited inside the abutment seat to move upward, so that the blank contacts the cutting wheel driven by the motor on the top of the machine base for cutting and segmentation processing;

[0014] 2. By rotating the threaded rod, the sliding block is displaced along the length direction of the threaded rod. The sliding blocks displace towards each other or away from each other, which is used to clamp and limit the blank of the cage or release the limit on the blank. When clamping, a clamping state is formed through the pressure rod and the screw bar to clamp and limit the arc-shaped end wall of the blank of the cage. The screw bar rotates and the screw bar displaces along the vertical direction of the side seat, facilitating the adjustment of the position of the screw bar to adapt to the arc-shaped end wall of the blank for clamping and positioning.

The slider 3 and the auxiliary base 5 are fixedly connected, and the auxiliary base 5 is rotatably connected to the lead screw 6. Moreover, the lead screw 6 is driven by the motor 7. The auxiliary base 5 and the sliding seat 8 are movably connected, and the sliding seat 8 and the abutting seat 9 are fixedly connected. Moreover, the abutting seat 9 and the sliding block 11 form a sliding structure through the abutting groove 10. By rotating the screw rod 4, the slider 3 is driven, and the slider 3 is displaced along the length direction of the screw rod 4, changing the positions of the slider 3 and the auxiliary base 5. After the auxiliary base 5 is displaced laterally, it drives the cage blank placed and clamped at the side end of the auxiliary base 5 to be displaced, changing the position of the cutting point of the blank, and conveniently and flexibly adapting to the processing and segmentation requirements of the blank. When the motor 7 at the top of the auxiliary base 5 operates, it drives the lead screw 6 to rotate, and the lead screw 6 drives the sliding seat 8 to be displaced along the length direction of the lead screw 6, changing the positions of the sliding seat 8 and the abutting seat 9. After the abutting seat 9 moves upward, it drives the cage blank clamped and limited inside the abutting seat 9 to move upward, bringing the blank into contact with the cutting wheel driven by the motor 7 at the top of the machine base 1 for cutting and segmentation processing;

The motor 7 at the top of the auxiliary seat 5 operates to drive the screw rod 6 to rotate, and the screw rod 6 drives the sliding seat 8 to displace along the length direction of the screw rod 6, changing the positions of the sliding seat 8 and the abutment seat 9. After the abutment seat 9 moves upward, it drives the cage blank clamped and limited inside the abutment seat 9 to move upward, bringing the blank into contact with the cutting wheel driven by the motor 7 at the top of the machine base 1 for cutting and segmentation processing. By rotating the threaded rod 12, the sliding block 11 is displaced along the length direction of the threaded rod 12, and the sliding block 11 moves towards or away from each other, used for clamping and limiting the cage blank or releasing the limit on the blank. During clamping, a clamping state is formed through the pressure rod 14 and the screw bar 16 to clamp and limit the arc-shaped end wall of the cage blank. The screw bar 16 rotates and the screw bar 16 is displaced along the vertical direction of the side seat 15, facilitating the adjustment of the position of the screw bar 16 to adapt to the arc-shaped end wall of the blank for clamping and positioning.
