specific Embodiment approach 1

[0022] Specific implementation mode one: combine Figure 1 to Figure 8 Describe this embodiment, this embodiment is an integrated asymmetric structure bearing channel measuring device, which includes a bearing outer groove position measuring instrument, characterized in that: the measuring device includes a pressure point bracket 1, a pressure point 2 and two A steel ball fulcrum 3, pressure point bracket 1 and two steel ball fulcrums 3 are connected with the bearing outer groove position measuring instrument, the two steel ball fulcrums 3 are respectively located on the upper and lower sides of the pressure point bracket 1, and the pressure point 2 is installed on the pressure point Point support 1, and pressure point 2 is located between two steel ball fulcrums 3.

specific Embodiment approach 2

[0023] Specific implementation mode two: combination Figure 2 to Figure 4 This embodiment will be described. The pressure point support 1 in this embodiment is connected into one body from the upper end support 1-1 and the support seat 1-2 sequentially from top to bottom.

[0024] The pressure point support 1 is processed by GCr15 material and designed as an irregular pentagon structure. The support seat is fixed with the instrument by two countersunk holes 1-2-1. The upper end support 1-1 rotates 45 degrees in the horizontal direction to make the pressure point Point 45 degrees to compress the channel surface. Drill a φ12+0.020mm connection hole 1-1-1 on the bracket, the surface roughness of the hole is Ra1.6um, mill a 1.5mm wide through-through groove 1-1-3 at the end of the bracket to the connection hole 1-1-1, and the side Drill a φ6.5mm through hole, tap M6 on the other side, press the 1.5mm gap through the bolt connection, and fix the pressure point. The pressure poin...

Abstract

The invention discloses an integrated asymmetric structure bearing channel measuring device, relates to a bearing channel measuring device, and aims to solve the problems that an existing measuring device and an existing measuring method cannot meet the actual measurement requirements for asymmetric structure bearings, are tedious in measuring process and are not suitable for process control of batch processing. The device comprises a bearing outer groove position measuring instrument, a pressure point support, a pressure point and two steel ball supporting points, the pressure point support and the two steel ball supporting points are connected with the bearing outer groove position measuring instrument respectively, the two steel ball supporting points are positioned on the upper side and the lower side of the pressure point support respectively, the pressure point is mounted on the pressure point support, and the pressing point is positioned between the two steel ball supporting points.

Description

technical field [0001] The invention relates to a measuring device for a bearing channel, in particular to an integrated asymmetric structure bearing channel measuring device, which belongs to the technical field of bearing measurement. Background technique [0002] Take a certain type of bearing as an example ( Figure 8 ), the outer ring of the bearing is an elastic support structure, the width of the outer ring is 92.3mm, the distance from the groove center to the reference end face is 72.8±0.015mm, the groove swing is 0.006mm, and the maximum outer diameter is 264mm. For the groove position and groove parallelism of deep groove ball bearings, the length measuring axis meter or profiler is used, and the measurement method has the following problems: [0003] 1. The length measuring instrument adopts the flip measurement method. By comparing the distance difference between the center line of the groove and the end faces on both sides, and controlling the total width of the...
