Problems solved by technology

The current radius of curvature template generally makes a ring first, grinds the inner hole according to the curvature radius of the template, and then cuts it out in pieces. The current sample can only be processed into a circular arc surface on one side. Upper and lower curvature templates cannot be made together
Once the inner hole of the ring is worn too large, it will only be scrapped, and it is difficult to process to the required dimensional accuracy of the radius of curvature

Embodiment Construction

[0023] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

[0024] as attached figure 1 , 2 As shown, the present invention discloses a processing technology for a radius of curvature template of an outer spherical ball bearing. 1) Carry out longitudinal and transverse forging on the blank until the thickness of the blank is 6.5-7mm. The blank is preferably high-carbon chromium bearing steel, Of course, this list is not limited, and other materials can also be used;

[0025] 2) Spheroidizing annealing, the hardness of spheroidizing annealing is Brinell hardness HBS190-210, which can be specifically Brinell hardness HBS190, or Brinell hardness HBS200, or Brinell hardness HBS210.

[0026] 3) Milling, put the blank after spheroidizing and annealing on the milling machine for milling into a sample, mill the thickness of the sample to 5.35-5.45mm, and process it...

Abstract

The invention relates to a processing technology of a curvature radius template of an outer spherical surface ball bearing. The processing technology comprises the following steps: 1) striking and forging blanks; 2) spheroidizing; 3) milling; 4) turning; 5) marking on two ends of a steel plate; 6) carrying out stress relief annealing; 7) quenching; 8) putting a template on a surface-grinding machine for processing; 9) coarsely grinding a circular arc camber; 10) extra tempering; and 11) accurately grinding the circular arc camber to obtain the finished product of the template. The invention also discloses a clamping device of the curvature radius template of the outer spherical surface ball bearing, and the clamping device is convenient in clamping and easy to process. The curvature radius template processed according to the invention can be ground for a plurality of times, has higher accuracy, is more accurate when detecting the spherical surface of the outer spherical surface ball bearing, and ensures the yield of products.

Description

technical field [0001] The invention relates to a processing technology of a curvature radius template of an outer spherical ball bearing and a clamping device thereof. Background technique [0002] When the outer spherical ball bearing is produced, because its outer diameter is a spherical shape, it is necessary to test the spherical surface before leaving the factory to check whether the spherical surface meets the requirements, so as to ensure that the products that meet the requirements flow into the market and ensure that consumers can rest assured. Use, while improving the reputation of the manufacturer. Existing methods of testing whether the spherical surface of the outer spherical ball bearing meets the requirements generally use the light gap method. When measuring, the curvature radius sample is buckled on the spherical surface, and the light leakage between the spherical surface and the curved surface of the sample is observed to determine the degree of agreement...
