Description
Technical field
The utility model belongs to the instrument for measuring bearings technical field, and what relate generally to is the improvement of a kind of bearing measuring instrument location fulcrum.
Background technology
In the Production of bearing process, the equipment of end face flexibility (CuB, CuC) that is used to measure all types of bearing rings of external diameter Φ 60mm～Φ 200mm mainly contains G 803 measuring instruments.As shown in Figure 4, this measuring instrument mainly is made up of movable buting iron 2, obturating plug 3, base 8, flat board 7, column 11, cantilever 12, location buting iron 9 etc.On flat board with HRC60 hardness, have the dovetail groove that is mutually 120 °, can be by a movable buting iron 2, two location that location buting iron 9 is realized surface level reliably, and two location fulcrums of side and fulcrum of spring are then realized control workpiece moving in surface level.During measurement, instrument by 10 dozens of gauge heads on the end face of workpiece 1, one week of rotational workpieces, the variation of instrument indication, i.e. the flexibility of workpiece end face for this reason, this measurement is the key point that guarantees bearing (particularly thrust bearing) planar processing precision.Yet, existing G 803 instrument for measuring bearings, the minimum outer diameter of measurement axis bearing ring is φ 60mm.For small-sized thrust bearing ring (for example 51103), its outside dimension is mostly less than φ 60mm, during with this apparatus measures, because the stroke of movable buting iron 2 and location buting iron 9 cramp bar length are fixed, and the size of three buting iron is bigger, make that three end face fulcrums that are separately fixed on three buting iron can not be further close, be that these three determined diameter of a circles of fulcrum in the same plane can not further reduce, its measurement range is restricted, can't effectively measures above-mentioned small size lasso.
Summary of the invention
The purpose of this utility model is the improvement that proposes a kind of bearing measuring instrument location fulcrum.Solved G 803 measuring instruments can't measurement axis bearing ring external diameter less than the problem of φ 60mm bearing face flexibility, increased its measurement range, and enlarged the center setting range, simplified the adjustment difficulty.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: it is positioned at flat board on the base and is provided with a movable buting iron, two location buting iron and cantilever, on cantilever, be fixed with the gauge head lever, the below end face of one end in contact workpiece of this gauge head lever, the other end contacts with measurement instrument; On flat board, have three dovetail grooves that are mutually 120 °, in each dovetail groove, be provided with the location fulcrum of forming by obturating plug, push rod, slide block and locknut, push rod is a sleeve structure, its upper end is provided with the connection boss and is threaded with obturating plug, the lower end has internal thread hole and is threaded with the top of slide block, dovetail groove on slide block bottom and the flat board is slidingly connected, and also is provided with two locknuts on the screw rod on slide block top.
The utility model is by the improvement to G 803 surveying instruments location fulcrum, makes it carry out flexibility to the bearing ring of large scale scope more and measures, and is able to measure the purpose of the bearing ring of external diameter φ 30～φ 200mm.Self just can finish accurate location this fulcrum, makes things convenient for the height control on the vertical direction, has enlarged the center setting range, has simplified the adjustment difficulty.By field experiment, satisfy on-the-spot request for utilization fully.Through the comparison of measured value, the measured value of its measured value and G803 is in full accord.It can satisfy the needs of production and processing thus, and precision has reached the technology controlling and process requirement.

Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 1: present embodiment is on the architecture basics of existing G 803 measuring instruments, on the flat board that is arranged on the base 8, have three dovetail grooves that are mutually 120 °, in each dovetail groove, be provided with the location fulcrum of forming by obturating plug 3, push rod 4, slide block 6 and locknut 14, (as shown in Figure 2) push rod 4 is a sleeve structure, its upper end is provided with the connection boss and is threaded with obturating plug 3, and the lower end has internal thread hole.(as shown in Figure 3) top of slide block 6 is screw rod, the bottom is a slide block, the upper screw of slide block 6 is connected with the threaded hole of push rod 4 lower ends, the slide block of slide block 6 bottoms and the dovetail groove on the flat board are slidingly connected, on the screw rod on slide block 6 tops, also be provided with two locknuts 14, the locknut of below is used for being connected of fastening slide block and flat board, and the locknut of top is used for being threaded of fastening push rod 4 and slide block 6, and can make things convenient for push rod 4 height control in vertical direction.Also be provided with a movable buting iron 2, two location buting iron 9 (fixing by buting iron clamper 15) on flat board, gauge head lever 10 is hinged on the support that is fixed on the cantilever, the below end face of one end in contact workpiece 1, and the other end contacts with measurement instrument.During measurement, instrument by 10 dozens of gauge heads on the end face of workpiece 1, one week of rotational workpieces, the variation of measurement instrument 13 indications, the i.e. flexibility of workpiece end face for this reason.
