Simple processing method of removing burrs of non-metal holder inner hole and end face junction

Abstract

Disclosed is a simple processing method of removing burrs of a non-metal holder inner hole and a end face junction. The external diameter of a non-metal holder (1) is D, and the width of the non-metal holder (1) is L. burr removing needs special tools. A push rod (3) is placed in a through hole of a jig (2) and the non-metal holder is arranged inside a clamping hole. The method includes the following steps: when a left hand or right hand turns the external diameter of the jig, the left hand or the right hand holds the special tools and removes the burrs of the inner hole at one end of the non-metal holder and the end face junction, pushes the push rod out of the non-metal holder from the clamping hole after burr-removing of one side is finished, relocating the non-metal holder into the clamping hole after burr-removing of the other side is finished, and the whole process of burr-removing of the inner hole at one end of the non-metal holder and the end face junction is finished by repeat of the above steps. Accuracy of the non-metal holder is not influenced, no scratch of a human finger is caused, labor intensity is lowered and working efficiency is improved.

Description

[0001] technical field [0002] The invention belongs to the technical field of bearing processing, and in particular relates to a simple processing method for removing burrs at the junction of an inner hole and an end face of a non-metallic cage. [0003] Background technique [0004] For non-metallic cages such as cages made of polytetrafluoroethylene, in the case of small size, due to the contact with the steel balls, the surface roughness of the parts that are in contact with the steel balls is required to be high, and non-metallic cages are not allowed. There are burrs at the joint between the inner hole of the frame and the end face. [0005] There are two methods for deburring the joint between the inner hole and the end face of the non-metallic cage: [0006] The first is the string light processing method, that is, put the non-metallic cage and the string light material into the string light machine, and use vibration and tumbling methods to remove sharp corners a...

Problems solved by technology

[0006] The first is the string light processing method, that is, put the non-metallic cage and the string light material into the string light machine, and use vibration and tumbling methods to remove sharp corners and burrs. Due to the small size and light weight of the non-metallic cage, During light processing, it is almost impossible to collide and rub with the string light material, and the burr cannot be completely removed, and it is easy to cause deformation and indentation during processing to destroy the original size and geometric accuracy of the non-metallic cage. , It is extremely difficult to separate the non-metallic cage from the string light material, which increases the labor intensity of the workers and reduces the processing efficiency

[0007] The second is to adopt the manual processing method, that is, to use the hand to pinch the cage and process it with a special tool. Because the angle and strength of the fingers are not easy to grasp, it is easy to deform and pinch the non-metallic cage with nails, which will affect the quality of the non-metallic cage. Dimensional and geometric accuracy, resulting in scrap

In addition, because the non-metallic cage itself is too small and light and the special knives are extremely sharp, workers' fingers are often scratched, causing safety hazards
