Description
Technical field
The utility model belongs to bearing detection field, relates generally to a kind of two half inner ring crossed roller bearing, four-point contact ball running accuracy pick-up unit, for the finished product accuracy detection of this class bearing.
Background technology
At present, robot, radar, medical instruments field critical piece bearing require to possess high precision, high rigidity, can precise positioning (moment of friction high conformity) performance.Traditional crossed roller, four point touching ball slewing bearing were also once applied to the occasions such as joint of robot, radar, medicine equipment, but along with robot, radar, medicine equipment performance requirement further improve, this class bearing can not meet the demands.Conventional cross roller, four point touching ball slewing bearing lasso have the soft band of quenching, and bearing reliability reduces; In addition, in structure, there is stopper, plug hole in lasso, during assembling, rolling body packs bearing into by stopper, then stopper is struck to people's plug hole (cooperation of plug hole stopper is transition fit), this structure can not guarantee to pack into the position consistency of stopper at every turn, even if that is to say that bearing ring can be worked into very high precision adding man-hour, but stopper can change with the relative position of plug hole during assembling, and bearing finished products precision, moment of friction can be affected.Crossed roller bearing, the four-point contact ball of two half inner rings or double semi outer rings, full hardened steel manufacture for bearing ring, does not have the soft band of quenching of turntable bearing lasso, has improved bearing reliability, has extended bearing serviceable life; On bearing arrangement, it does not have plug hole, has eliminated the impact of stopper on bearing accuracy, moment of friction, can realize the high running accuracy of bearing, high rigidity, the good consistance of moment of friction.This class bearing is applied in the field that robot, radar, medicine equipment etc. have accurate positioning requirements more and more.
Two half inner rings or double semi outer rings bearing, its pair half lasso has uses coupling bolt part, and the product yet having does not have coupling bolt.Which kind of situation no matter, product is under negative play (high rigidity) state, and the faying face of two half lassos is difficult to realize and combines closely, and under this state, cannot realize the Measurement accuracy of product running accuracy.At present, just in process, with bearing parts accuracy guarantee Product Precision.This assessment method makes bearing products quality in kind have hidden danger.
Summary of the invention
The purpose of this utility model is to provide a kind of two half inner ring crossed roller bearing, four-point contact ball bearing rotation precision pick-up unit, realizes the accuracy detection of this class bearing.
The utility model completes the technical scheme that its invention task is taked: it comprises base and gland, hold-down bolt, meter, described base is cylindrical, its bottom has end limit, the diameter on end limit is greater than the diameter on base top, gland is positioned at the top of base, both connect by hold-down bolt, first inner ring of measured bearing and second inner ring of measured bearing are enclosed within on the external diameter of the base between gland and end limit, described meter consists of radial measurement table and axial meter, radial measurement table contacts with the outer wall of measured bearing outer ring, the end contact of axial meter and measured bearing outer ring.
Described base upper surface is lower than the end face of measured first inner ring of bearing; The inner ring internal diameter of described measured bearing is transition fit with the top external diameter of measuring base; The bottom end limit of described base and the diameter of gland are less than the outside dimension of measured bearing inner race.
The utility model is simple in structure, easy to detect, effective.The quantity of hold-down bolt, nut, according to the size of product size, is distributed on base, can be three groups, four groups or more groups; Meter is fixed with magnetic force dial framework or other servicing unit, indicator contact outer ring external diameter, end face.During detection, bolt, gland compress bearing inner race, swivel bearing outer ring, and meter shows that numerical value is diameter run-out, the axial runout of bearing outer ring, thereby realize the accuracy detection of this class bearing, (two half inner-ring bearings are when work, and inner ring is fixed, outer ring rotation; In standard, only require the running accuracy of measuring bearing outer ring).
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1, base, 2, radial measurement table, 3, axially meter, 4 glands, 5, hold-down bolt, 6, first inner ring of measured bearing, 7, measured bearing outer ring, 8, second inner ring of measured bearing, 9, clamp nut.
Embodiment
By reference to the accompanying drawings 1, specific embodiment of the utility model is illustrated:
As shown in Figure 1: the utility model comprises base 1 and gland 4, hold-down bolt 5, meter, described base 1 is cylindrical, its bottom has end limit, the diameter on end limit is greater than the diameter on base top, gland 4 is positioned at the top of base 1, in base, be provided with bolt hole, both connect by hold-down bolt 5, first inner ring 6 of measured bearing and second inner ring 8 of measured bearing are enclosed within on the outer wall of base of gland 1 bottom, described meter 1 consists of radial measurement table and axial meter 3, radial measurement table 2 contacts with the outer wall of measured bearing outer ring 7, the end contact of axial meter 3 and measured bearing outer ring 7.Described base 1 upper surface, lower than the end face of first inner ring 6 of measured bearing, guarantees that gland 4 can compress bearing; The inner ring internal diameter of described measured bearing (internal diameter of first inner ring 6 of measured bearing and second inner ring 8 of measured bearing), with the top external diameter of measuring base 1 be transition fit; The bottom end limit of described base 1 and the diameter of gland 4 are less than the outside dimension of measured bearing inner race.
During testing product, measured bearing is positioned over measurement mechanism base 1, and even fastening hold-down bolt 5, nut 9 make gland 4 compress bearing inner race; Rotation measured bearing outer ring 7, radial measurement table 2 and axially meter 3 show that numerical value is diameter run-out, the axial runout of measured bearing outer ring 7.
