Specific example 7 of a bearing channel dimension measuring tool provided by the present invention:
In the bearing channel dimension measuring tool embodiment 1 of the present invention, the guide sleeve 2 comprises a plug-in block 21, the plug-in block 21 is used for plugging in a fixed jaw and is provided with an opening, a fastening block 22 is assembled in the opening, the fastening block 22 is used for fixedly connecting with the fixed jaw, and two sides of the plug-in block 21 are provided with matching blocks 23 used for sliding matching with the measuring mechanism 3. In the present embodiment, the insertion block 21 and the engagement block 23 may be fixed, and the engagement block 23 may be fastened by bolts from the side of the insertion block 21 where the engagement block 23 is not provided after being mounted on the claw, and the fastening block 22 may be omitted.
Specific example 8 of the bearing channel dimension measuring tool provided by the present invention:
In the bearing channel dimension measuring tool embodiment 1 of the present invention, the guide engaging structure is a guide rail groove structure provided between the engaging block 23 and the measuring mechanism 3. In this embodiment, the guide rail and guide groove structure may also be a structure in which a round rod and a bar-shaped through hole slide in a matched manner.
Specific example 9 of a bearing channel dimension measuring tool provided by the present invention:
in the bearing channel dimension measuring tool embodiment 1 of the present invention, the guide rail guide groove structure is provided with a plurality of guide grooves on the fitting block 23. In this embodiment, when the width specification of the bearing 4 to be measured is not greatly different, only two grooves, i.e., one measurement height, may be provided, and used for measuring the bearings having similar widths in the same width section.
