Description
Technical field
The utility model relates to bearing measuring device technique field, particularly relates to a kind of measurement mechanism of double-row bearing ditch spacing.
Background technology
Double-row angular contact bal bearing is mainly used on the front hub of car, and it can bear larger radial load is main radial and axial joint load and moment load, the axial displacement of two aspects of restrictive axes.Its geometric accuracy, dimensional accuracy and running accuracy etc. are required relatively stricter, and two ditch centre distance of outer ring are the key technical indexes of this bearing.Tiltable between the inside and outside circle of double-row angular contact bal bearing is limited, reduces its pitch angle by optimizing Bearing inner design.If there is pitch angle between the inside and outside circle of bearing, will affect the life-span of bearing, and cause bearing operation precise decreasing simultaneously, running noise increases.So just seem very important for control two ditch centre distance in mill process, but there be limited evidence currently of has accurate detecting instrument.And adopting now contourgraph to carry out the measurement of ditch spacing, the reason due to this instrument is not easy to use at plant site, also just reduces ditch distance measurement frequency, increases the output of defective products.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of measurement mechanism of double-row bearing ditch spacing, easy to install, can the dimensional parameters of accurate measurement products, solves original apparatus measures inconvenient, the problem that degree of accuracy is not high.
The utility model solves the technical scheme that its technical matters adopts: the measurement mechanism providing a kind of double-row bearing ditch spacing, comprise base, described base is round platform and the radians such as its bottom surface are mounted with four foundation seat struts, described base center position is mounted with worktable, table bar is fixed with on the upside of it, described table bar upper end is fixedly connected with clock gauge, a contact lever is had immediately below the gauge head of described clock gauge, described contact lever lower end is passed the mounting hole of worktable and base successively and is connected and fixed with one end of spring leaf, the spring leaf pillar of the other end of described spring leaf and the opposite side of Its lower side is connected and fixed, this spring leaf centre position is fixedly connected with measurement take-off lever, described measurement take-off lever passes the mounting hole of base and worktable successively and its upper end is fixed with ball contact tip, the first spring is connected with between the lower end of described measurement take-off lever and base bottom surface.
One as measurement mechanism described in the utility model is supplemented, and the center position on the upside of described worktable is placed with workpiece.
One as measurement mechanism described in the utility model is supplemented, and described spring leaf has two panels and both are arranged in parallel.
