Description

A kind of measurement mechanism of double-row bearing ditch spacing
Technical field
The utility model belongs 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.The simple surveying instrument that a convenience uses in production scene is designed based on current present situation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of measurement mechanism of double-row bearing ditch spacing, inconvenient to solve original apparatus measures, 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, base is round platform and the radians such as base end face are mounted with four foundation seat struts, described base center is mounted with a worktable, submounts side is fixed with table bar, table bar upper end is fixedly connected with clock gauge, a contact lever is had immediately below the gauge head of clock gauge, contact lever lower end is passed the mounting hole of worktable and base successively and is connected and fixed with spring leaf one end, the spring leaf pillar of the opposite side below the spring leaf other end and base is connected and fixed, spring leaf centre position is connected and fixed the lower end of a measurement take-off lever, the upper end of measurement take-off lever passes the mounting hole of base and worktable successively and the upper end of measurement take-off lever is fixed with ball contact tip, the first spring is connected with between measuring below the lower end of take-off lever and base.
Center above described worktable is placed with workpiece.
Described spring leaf has two panels and position between spring leaf is parallel relation.
Beneficial effect
The utility model is easy to install, can the dimensional parameters of accurate measurement products.
Accompanying drawing explanation
Fig. 1 is the utility model front view.
Fig. 2 is the utility model vertical view.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
Embodiment 1
As shown in Fig. 1 ~ Fig. 2, a kind of measurement mechanism of double-row bearing ditch spacing, comprises clock gauge 1, table bar 2, base 3, and worktable 4, measures take-off lever 5, ball contact tip 6, the first spring 7, spring leaf 8, spring leaf pillar 9, pedestal column 10, workpiece 11,
1) determine ball contact tip 6 diameter, select the steel ball that ditch curvature is large.
2) in order to reduce the impact of ring width parallel error, need to carry out one-point measurement on lasso.
3) between ball contact tip 6 and worktable 4, put into the gauge block such as a piece, wait the height of gauge block to be A, ball contact tip 6 can move up and down at measurement take-off lever 5, fastening ball contact tip 6 after moving ball gauge head 6 contacts with gauge block such as grade.A=a-Dw/2, a=(C-H)/2, in formula, a is hyposulculus position, and C is ring width, and H is two ditch centre distance.
4) gauge block will to be taken off etc. after clock gauge 1 pair of zero-bit.
5) put into surveyed workpiece 11, ball contact tip 6 and workpiece 11 raceway groove are matched, fixing auxiliary fulcrum after maximizing.Lasso is determined a bit, make this alignment with the ball gauge head 6, as ball contact tip 6 and channel junction reading numerical values a1 on showing after touch, the deviate a2 of another raceway groove is measured in lasso upset at same position
6) measure the height C1 of this point, then can calculate two ditch spacing is H1=C1-a1-a2.
