Description
Technical Field
The invention belongs to the technical field of grinding, and particularly relates to a method for machining an end face of a double-end-face asymmetric bearing.
Background
In daily production, the double-end-face asymmetric bearing is widely applied in production and life, but because the two end faces of the inner and outer rings of the double-end-face asymmetric bearing are different in size, the machining allowance of a general large end face is larger than that of a small end face, and the position of a channel cannot be guaranteed by changing the rotating speed and the granularity of a grinding wheel by adopting a double-end-face grinding process, the end face of the double-end-face asymmetric bearing is ground in a single-face grinding mode in the prior industry, so that the machining is difficult, and time and labor are wasted.
Disclosure of Invention
The invention provides a method for processing an end face of a double-end-face asymmetric bearing in order to solve the problems, and aims to solve the problem that the traditional method for processing the end face of the double-end-face asymmetric bearing only can be used for single-side grinding.
In order to realize the purpose, the invention adopts the technical scheme that:
a method for processing the end face of a double-end-face asymmetric bearing is characterized by comprising the following steps:
the machining allowance of the first end face of the original lathed blank of the double-end-face asymmetric bearing is smaller than that of the second end face of the original lathed blank;
and (3) changing the blank to enable the machining allowance of the first end face to be the same as that of the second end face, and grinding the double end faces of the double-end-face asymmetric bearing by using a double-end-face grinding method.
Preferably, the first end face is calculated to increase the machining allowance compared with the original first end face of the machined blank.
Preferably, the machining allowance of the second end face is equal to the machining allowance of the original machined blank second end face.
Preferably, the grinding time of the first end face is the same as that of the second end face.
Preferably, the area of the first end face is smaller than the area of the second end face.
Preferably, the area of the first end face of the original lathed blank is smaller than the area of the second end face of the original lathed blank.
Preferably, the first end face and the second end face are machined by a double-ended grinding machine.
Preferably, the double-ended grinding machine is particularly a vertical double-ended grinding machine.
Preferably, the double-end-face asymmetric bearing is an angular contact ball bearing.
The invention has the advantages that: the method for machining the end face of the double-end-face asymmetric bearing overcomes the defects that the existing double-end-face asymmetric bearing end face machining can only be used for single-face machining and is complex in process, saves machining time, reduces labor cost, and is very convenient and practical.

FIG. 2 is a turning schematic of an unmodified double-ended grinding turning blank embodiment of a double-ended asymmetric bearing end-face machining method of the present invention.
Detailed Description
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
It should be noted that the embodiments described below and the technical features in the embodiments may be combined with each other without conflict.
See FIGS. 1-2 for the following:
specifically, the method comprises the following steps:
a method for processing the end face of a double-end-face asymmetric bearing comprises the following steps:
the machining allowance of the first end face 3 of the original lathed blank of the double-end-face asymmetric bearing is smaller than that of the second end face 4 of the original lathed blank;
and (3) changing the blank to enable the machining allowance of the first end face 1 to be the same as that of the second end face 2, and grinding the double end faces of the double-end-face asymmetric bearing by using a double-end-face grinding method.
The first end face 1 is calculated to increase the machining allowance compared with the original machined blank first end face 3.
The machining allowance of the second end face 2 is equal to the machining allowance of the original turning blank second end face 4.
The grinding time of the first end face 1 is the same as that of the second end face 2.
The area of the first end face 1 is smaller than the area of the second end face 2.
The area of the first end face 3 of the original turning blank is smaller than the area of the second end face 4 of the original turning blank.
The first end face 1 and the second end face 2 are machined by a double-ended grinding machine.
The double-end surface grinding machine refers in particular to a vertical double-end surface grinding machine.
The double-end-face asymmetric bearing particularly refers to an angular contact ball bearing.
After calculating the machining allowance of the second end face of the original machined blank, calculating the machining allowance of the first end face 3 of the original machined blank, which is less than the machining allowance of the second end face 4 of the original machined blank, and then changing the machining allowance of the first end face 1 of the blank produced next time to enable the machining allowances of the first end face 1 and the second end face 2 to be the same, so that the machining allowances with the same two end faces can be removed in one-time machining by using a double-end-face grinding machine, and one-time machining forming of the double-end-face asymmetric bearing is completed.
