Description
Technical field
The present invention relates to a kind of drilling-hole positioning device, more particularly to a kind of mechanical processing is filled with bearing outer ring boring positioning
It puts, belongs to technical field of mechanical processing.
Background technology
Bearing is a kind of important spare part in contemporary mechanical equipment.Its major function is the mechanical rotary body of support, is reduced
Friction coefficient in its motion process, and ensure its rotating accuracy, the linear motion bearing form of early stage is exactly in row's skid plate
One row's rod of lower placement.Modern linear motion bearing uses same operation principle, only replaces roller with ball sometimes.
Simplest swivel bearing is axle sleeve bearing, it is a bushing being clipped between wheel and wheel shaft.It is this to design then quilt
Rolling bearing substitutes, and is exactly to substitute original bushing with many cylindrical rollers, each rolling element is just as an individual vehicle
Wheel, according to national statistics office data, Chinese bearing mnanufacture industry size (20,000,000 yuan of annual sales revenue or more) enterprise in 2011
1416 enterprises are shared, whole year realizes 1932.11 hundred million yuan of total industrial output value, increases by 27.59% on a year-on-year basis；Income from sales is
1910.97 hundred million yuan, increase by 30.30% on a year-on-year basis；125.23 hundred million yuan of total profit, it is 26.54% to increase compared with last year.Expect 2015
Year, China's bearing yield is expected to more than 28,000,000,000 sets, and main business income is expected to reach 210,000,000,000 yuan, becomes global maximum axis
It holds and produces and sells base.
Bearing is classified as sliding bearing：Sliding bearing regardless of Internal and external cycle also without rolling element, usually by wear-resistant material system
Into.It is usually used in low speed, underloading and filling lubricating oil and mechanical rotation position difficult in maintenance, oscillating bearing：The cunning of oscillating bearing
Dynamic contact surface is spherical surface, is primarily adapted for use in pendulum motion, banking motion and rotary motion, rolling bearing：Rolling bearing presses it
The loading direction or the difference of nominal contact angle that can bear are divided into radial bearing and thrust bearing.Wherein radial contact bearing is
Nominal contact angle is 0 radial bearing, and centripetal angular contact bearing is more than 0 to 45 radial bearing for nominal contact angle.Axially connect
Contact bearing is the thrust bearing that nominal contact angle is 90, and thrust angular contact bearing is more than 45 but pushing away less than 90 for nominal contact angle
Power bearing, wherein rolling bearing are relatively broad in application in machine equipments.
Existing bearing is typically used in automatically or semi-automatically equipment, these right equipment are required for needing boring positioning,
General positioning device bearing is different from installation specification, can not change with the variation of bearing, and positioning is unstable, often replaces one
Secondary to need to edit parameter again, labor intensity is big, and very troublesome, running accuracy is bad, if supported flange makes bearing load
Ability is excessive, leverages development and application of the bearing in production technology.
