Problems solved by technology
The original assembly mold has 41 arc-shaped grooves without steel balls and no counting template. There has been a phenomenon that steel balls or spacers are installed incorrectly (two steel balls or spacers are arranged in parallel). This hidden danger, the wrong product will appear uneven force when used, so it will reduce the service life of the bearing

Embodiment Construction
[0032] In order to better understand the technical solution of the present invention, it will be described in detail below through specific embodiments in conjunction with the accompanying drawings:
[0033] see figure 1 , the conventional angular contact ball bearing includes an inner ring 31, an outer ring 34, a plurality of steel balls 32 and spacers 33 with the same number of steel balls. There is a channel, steel balls 32 and spacer blocks 33 are arranged in the channel on the outer peripheral surface of the inner ring 31 at intervals, and the outer ring 34 is thermally sleeved on the periphery of the steel balls 32 and spacer blocks 33 after being heated.
[0034] The assembly mold of the angular contact ball bearing of the present invention includes a counting template and an error-proofing mold, and the material of the counting template and the error-proofing mold is bakelite or a plastic plate.
[0035] see again Figure 2 to Figure 4 , the counting template 1 is us...

Abstract
The invention discloses an assembly mould of an angular contact ball bearing, which comprises a counting template and an error-proofing mould, wherein the counting template is a flat plate, the edge of the flat plate is surrounded by a stripper plate, one surface of the flat plate is uniformly provided with steel ball grooves (the number of the steel ball groove is same as that of steel balls forassemble a bearing, and the diameter of the steel ball groove is less than that of the steel ball), and the other surface of the flat plate is longitudinally provided with two grooves for placing isolation blocks; and the error-proofing mould is a torus, the upper end face of the torus is provided with a positioning ring groove, the positioning ring groove is a two-step-shaped groove (the inner part is lower than the outer part), an internal groove of the positioning ring groove is a straight groove for positioning an inner ring, an external groove of the positioning ring groove is an inverted-ladder-shaped groove for accommodating the steel balls and the isolation blocks, and the external wall of the inverted-ladder-shaped groove is uniformly and radially provided with arc grooves (the number of the arc groove is same as that of the steel balls). The invention also discloses a method for assembling the angular contact ball bearing. By adopting the assembly mould and the assembly method in the invention, the phenomenon of missing loading and misloading of the steel balls and the isolation blocks can be prevented.
Description
technical field [0001] The invention relates to an assembly mold of an angular contact ball bearing and an assembly method thereof. Background technique [0002] Angular contact ball bearings have an outer ring, an inner ring, steel balls and spacers. A plurality of steel balls and spacers are evenly spaced and embedded in the pockets on the peripheral surface of the inner ring. After the outer ring is heated, it is thermally sleeved on the steel balls. and isolate the perimeter of the block. If the product requires forty-one steel balls and spacers to be installed crosswise in the bearing groove. In the assembly process, people will inevitably make mistakes, such as under-installation or wrong installation of steel balls and spacers. The original assembly mold has 41 curved grooves without steel balls and no counting template. There have been a phenomenon of misinstallation of steel balls or spacers (two steel balls or spacers are arranged in parallel). If it is not ruled...
