Abstract

The utility model relates to an internal complex round measuring device of a cylindrical roller bearing of a drawn cup, which is composed of a detection ring and a bracket, wherein the bracket is composed of a stanchion, a base and a working table; an internal complex round ring gauge group composed of internal complex round ring gauges are arranged on the stanchion of the bracket, and the internal complex round ring gauges of each group are arranged in the descending order according to the diameter dimensions of the internal complex round ring gauges; the internal complex round ring gauge with the maximum dimension is arranged at the bottom of the stanchion, the internal complex round ring gauge with the minimum dimension is arranged on the top of the stanchion, and the internal complex round ring gauges are fixedly connected by socket head screws. The utility model has the measuring method that a bearing is pressed in the detection ring first; then the bearing pressed in the detection ring and the detection ring are sheathed on the ring gauge group together; the bearing and the detection ring freely fall; when the bearing stops on any of internal complex round ring gauge rings, the utility model can measure the exact value of the internal complex round diameter of the bearing. The utility model can be extensively used for the assembly and the stamping production of bearings.

Description

The device that fourth contact is measured in a kind of drawn cup cylinder roller bearing
Technical field
The utility model belongs to the bearing measuring technical field, the device that fourth contact is measured in especially a kind of drawn cup cylinder roller bearing.
Background technology
The drawn cup cylinder roller bearing is to be pressed in the bearing seat of certain size to work, the bearing seat internal diameter is little than bearing outside diameter, bearing outer ring in use is compressed, so outer raceway that provides among the product figure, some dimensional characteristics such as interior fourth contact are meant that bearing is pressed into the dimensional characteristic in the specific dimensions detection ring, rather than the size of bearing under free state, this has just determined that the fourth contact diameter detects different with conventional cylinder roller bearing in this class bearing, it is bearing to be pressed into to detect interior fourth contact in the detection ring earlier, thereby be not suitable for absolutely checking, every batch can only be by the selective examination of technology sampling, and just the accuracy requirement to assembling trap precision and detection is very high for this.Interior fourth contact diameter detection method has usually: 1, cooperate the percentage sheet to take out interior fourth contact diameter with supporting sample circle; 2, with the logical no-go gage inspection of interior fourth contact diameter; 3, measure with the circular cone axle.Take out the play method with the percentage sheet for first kind and detect, the factor that influences its testing result is a lot, and it is big to detect error, does not adopt; Second method detects with logical no-go gage, can only do qualitative detection, can only judge whether it is qualified, but the concrete size of fourth contact diameter in can not detecting, and, can only be used for finished product detection, and inapplicable assembling trap because of error appears in everyone gimmick Different Results often; Measure with the circular cone axle, can be according to bearing fourth contact diameter in the position calculation of circular cone axle goes out, but circular cone axle manufacture difficulty is big, and the interior fourth contact diameter of measuring need calculate.
Summary of the invention
The utility model proposes the device that fourth contact is measured in a kind of drawn cup cylinder roller bearing, can directly obtain the exact value of fourth contact diameter in the bearing, thereby the roller size of fourth contact deviation when the tolerance intermediate sizes in can determining provides roller flowing water tolerance.
The technical scheme that its technical matters that solves the utility model adopts is, the device that fourth contact is measured in a kind of drawn cup cylinder roller bearing is made up of detection ring 2, support 3, support 3 is made of pillar, base, worktable, the interior fourth contact ring gauge group that is made of interior fourth contact ring gauge 1 is installed on the pillar of support 3, fourth contact ring gauge 1 is more than totally ten in one group, every group interior fourth contact ring gauge 1 is arranged from big to small by its diameter dimension, full-size is in a column bottom, minimum dimension is connected and fixed with socket head cap screw 5 in post top portion.Screw 5 can not kill, avoid influencing testing result because of the coaxiality error of ring gauge external diameter and internal diameter, it uses measuring method, at first bearing 4 is pressed in the detection ring 2, the bearing 4 that will be pressed into again in the detection ring 2 is enclosed within on the ring gauge group with detection ring 2, bearing 4 is under the weight effect of own wt and detection ring 2, free-falling, bearing 2 is parked on the interior fourth contact ring gauge 1 of which piece, just can measure the exact value of fourth contact diameter in this bearing 4, remember size, with hand bearing 4 and detection ring 2 be lifted down again, avoided testing result to vary with each individual, this kind detection method through practice test accurately and reliably.Can in bearing assembling and punching production, use widely.This class bearing is general all very big in batches, bearing 4 is assemblied on the automatic assembly line and carries out, productive temp is fast, detect with interior fourth contact ring gauge 1, can directly obtain the exact value of fourth contact diameter in the bearing 4, thereby the roller size of fourth contact deviation when the tolerance intermediate sizes in can determining provides roller flowing water tolerance, accurately and reliably.Fourth contact ring gauge 1 in the stamping procedure of outer ring, using, can control the drawn cup size, exactly same outer ring is pressed into respectively in the detection ring 2 before thermal treatment, after the thermal treatment, measure outer raceway size and adorn the interior fourth contact size of unidimensional roller measurement all constant, fourth contact ring gauge 1 can directly accurately provide die size in utilizing, can determine raceway punching press size, and the wear condition of energy supervision molding.
The beneficial effects of the utility model are: can directly obtain the exact value of fourth contact diameter in the bearing, thereby the roller size of fourth contact deviation when the tolerance intermediate sizes in can determining provides roller flowing water tolerance, accurately and reliably.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, interior fourth contact ring gauge, 2, detection ring, 3, support, 4, bearing, 5, screw.
Embodiment
Fourth contact tolerance in the bearing is divided into several groups, and we make one group of interior fourth contact ring gauge 1 by 3 μ grouping, fourth contact ring gauge 1 is totally ten in one group, and during making, the correct grinding size makes same size, grind out each ring gauge 1 size by lappingout then, after ring gauge 1 had been made, marking, size also sent metering to identify.Fourth contact ring gauge group on the pillar of support 3, installing then, interior fourth contact ring gauge 1 is arranged from big to small by its diameter dimension, and full-size is in a column bottom, and minimum dimension is connected and fixed with socket head cap screw 5 in post top portion.At first bearing 4 is pressed in the detection ring 2, the bearing 4 that will be pressed into again in the detection ring 2 is enclosed within on the ring gauge group with detection ring 2, bearing 4 is under the weight effect of own wt and detection ring 2, free-falling, bearing 2 is parked in fourth contact ring gauge 1 encircles in which piece, and we just can measure the exact value of fourth contact diameters in this bearing 4.
