specific Embodiment approach 1

[0024] Specific Embodiment 1: A device for making the thickness of the cage lock claw consistent, including No. 2 control motor 1-2, No. 1 motor frame 1-3, No. 2 motor frame 1-4, power supply 2, cage 7, Tool 8, base 12, machine base 14, No. 1 control motor 1-1, air pump 3, No. 1 mechanical arm 4, No. 2 mechanical arm 5, alignment mechanism 5-1, telescopic cylinder 6 and knife rod 9;

[0025] The base 14 is arranged on the upper end surface of the base 12 and is fixedly connected with the base 12. The upper end surface of the base 14 is provided with a power supply 2 and an air pump 3. The front end of the base 14 is provided with a cylinder, and one end of the cylinder Fixedly connected with the base 14, the side of one end of the cylinder is provided with a No. 1 motor frame 1-3, and the No. 1 control motor 1-1 is fixedly connected with the No. 1 motor frame 1-3 by screws, and the No. 1 control motor 1-3 is fixedly connected with the No. 1 motor frame 1-3 by screws. 1 is conn...

specific Embodiment approach 2

[0028] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: a device that makes the thickness of the locking claw of the cage consistent, and also includes a screw 10, a screw arm 11, a control motor 13 on the 3rd, and a transmission belt 13- 1. The driving wheel 13-2 and the driven wheel 13-3. The other side of the base 12 is provided with a No. 3 control motor 13. The No. 3 control motor 13 is positioned and connected with the driving wheel 13-2 through a transmission shaft. The driving wheel 13- 2. Connect the driven wheel 13-3 through the transmission belt 13-1, and the driven wheel 13-3 is positioned and connected with one end of the lead screw 10. One end of the lead screw arm 11 is provided with a threaded through hole in the axial direction, and the other end of the lead screw 10 is connected to the screw. The threaded through hole of the screw arm 11 is threadedly connected, and the other end of the screw arm 11 is provided with t...

specific Embodiment approach 3

[0030] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that: the inside of the through hole at one end of the No. 1 mechanical arm 4 is provided with a keyway, and is provided with a positioning key, and No. 1 is controlled by the positioning key. The transmission shaft of the motor 1-1 is positioned and connected to one end of the No. 1 mechanical arm 4, which limits the degree of freedom of the No. 1 mechanical arm 4 and the transmission shaft along the axis of the circumference.

Abstract

The invention discloses a device and method for enabling the thickness of retainer locking claws to be consistent, and relates to the technical field of bearing structure machining. For solving the problem that when the cutter is aligned with the centers of the retainer locking claws manually, and the thicknesses of two sides of a part of the locking claws of 12 pairs of the locking claws in the machined single retainer are inconsistent, the device comprises a second control motor, a power supply, the retainer, the cutter, a bottom base, a machine base, a first control motor, an air pump, a first mechanical arm, a second mechanical arm, an alignment mechanism, a telescopic air cylinder and a cutter bar, wherein before the bearing retainer is machined, centering and positioning are carriedout on the cutter and the retainer through the alignment mechanism, after the centering and positioning is confirmed, the locking claws of the bearing retainer is machined, and the situation that dueto the fact that the cutter is not consistent with the centers of the retainer locking claws, the thickness of the two sides of the part of the locking claws of the machining completed retainer are caused to be inconsistent is avoided. The device and the method are suitable for the centering and positioning the cutter and the retainer locking claws and enabling the thickness of the two sides of the machined retainer locking claws to be consistent.

Description

technical field [0001] The invention relates to the technical field of bearing structure processing. Background technique [0002] Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling body and cage. The function of the inner ring is to cooperate with the shaft and rotate together with the shaft; the function of the outer ring is to cooperate with the bearing seat to play a supporting role; the rolling body The locking claws of the cage evenly distribute the rolling elements between the inner ring and the outer ring, and its shape, size and quantity directly affect the performance and life of the rolling bearing; the locking claws of the cage can evenly distribute the rolling elements, Prevent the rolling body from falling off, and guide the rolling body to rotate to lubricate. [0003] At present, in the process of machining the cage of the bearing, it is usually necessary to manually align the tool with the center of the lock claw of the c...
