Abstract
The invention discloses a measuring tool for checking a central hole of a roller. The measuring tool for checking the central hole of the roller comprises a micrometer gauge and a main measuring tool body, wherein the main measuring tool body is in a cylindrical structure, and the center of the main measuring tool body is axially provided with a through hole; a fixed rod of the micrometer gauge is arranged in the through hole to be fixedly connected with the main measuring tool body; and the central position of the bottom of the main measuring tool body is provided with a groove. The measuring tool disclosed by the invention has the advantages of simple structure and convenience for operation, ensures good contact of the end surfaces of the measuring tool and the roller by arranging the groove at the bottom of the main measuring tool body and ensures that the micrometer gauge can not be damaged when clamped by enabling the fixed rod of the micrometer gauge to be uniformly stressed in such a way that the micrometer gauge is clamped through a lining.
Description
Technical field
The present invention relates to measurer, relate in particular to a kind of roller centre hole check measurer.
Background technology
Now the society along with technology fly suddenly advance by leaps and bounds, various advanced persons' lathe meets the tendency.The running accuracy of lathe requires also increasingly high, and the precision that really influences it is with regard to several, and its centre bearer plays a part to closing.It directly affects serviceable life etc. of running accuracy, machining precision and the lathe of lathe.In case in the process of installing, make a fault, with the use that directly influences whole lathe.The particularly assembling of high-precision rolling bearing.
Want high-precision running in bearings at first need carry out maximum precision to the size of each parts of bearing itself; In the assembling process of bearing roller and retainer; The degree of depth of bearing end center pit is to influence the accurately key factor of running of bearing, and therefore the detection to the bearing roller center pit degree of depth is very necessary.
Summary of the invention
The technical matters that the present invention solves is: a kind of bearing roller center pit check measurer is provided, measures the degree of depth in roller centre hole easily.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of roller centre hole check measurer; Comprise clock gauge and measurer main body, said measurer main body becomes cylindrical structure, and its central shaft is to being provided with through hole; The fixed bar of said clock gauge is arranged in the through hole and is fixedly connected with said measurer main body, and said measurer bottom part body center is provided with groove.
Further, be provided with lining in the said through hole, said lining is fixedly connected with the measurer main body, and the fixed bar of said clock gauge is fixedly connected with the measurer main body through lining.
Further, said lining adopts resilient material to make.
Further, vertical with the said center pit clamping bolt hole that is provided with on the said measurer main body.
Beneficial effect of the present invention is: simple in structure, easy to operately in the measurer bottom part body groove is set and guarantees that the measurer end face well contacts with roller end face, be not damaged when making the stressed even assurance clock gauge clamping of clock gauge fixed bar through lining clamping clock gauge.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the roller centre hole inspected number structure synoptic diagram of signing an undertaking.
Fig. 2 is a measurer agent structure synoptic diagram.
Among the figure:
1, clock gauge; 2, measurer main body; 3, lining; 4, steel ball; 5, roller; 6, through hole; 7, clamping bolt hole; 8, fixed bar; 9, sounding rod; 10, groove.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Like Fig. 1, shown in 2, in present embodiment, a kind of roller centre of the present invention hole check measurer; It comprises measurer main body 2 and clock gauge 1, and said measurer main body 2 is a cylindrical structure, its center position axis to offer through hole 6; Be provided with lining 3 in the said through hole 6; On measurer main body 2, offer clamping bolt hole 7 with said through hole 6 vertical directions, said clamping bolt hole 7 is communicated with said through hole 6, and the fixed bar 8 of said clock gauge 1 is fixedly mounted on the measurer main body 2 through lining 3; Said lining 3 adopts resilient material to make, and clamps through the 3 pairs of clock gauges 1 of bolt extruding lining that are provided with in the clamping bolt hole 7; Said measurer main body 2 bottom centre positions offer groove 10.
In roller 5 center pits, put into the steel ball 4 of standard during work; And guarantee that steel ball 4 surperficial peaks are higher than roller 5 upper surfaces; Roller 5 center pits check measurer and roller 5 are aligned, measurer main body 2 lower surfaces are contacted with roller 5 end faces, this moment, the sounding rod 9 of clock gauge 1 will be in the effect lower compression of steel ball 4; Can on the clock gauge dial plate, demonstrate reading, can calculate the roller centre hole depth according to reading and steel ball 5 diameters.
After between clock gauge 1 and the measurer main body 2 lining 3 being set, carry out clamping through clamping bolt hole 7 again; Can be so that fixed bar 8 be stressed even; Can in clamping process, not be extruded distortion; Measurer main body 2 bottom centre positions are provided with and accommodate the steel ball 4 that is higher than roller 5 upper surfaces when groove 10 is convenient to measure, and can effectively contact with measurer main body 2 lower surfaces to guarantee roller 5 end faces, guarantee that measurement data is accurate.
What need statement is; Above-mentioned embodiment only is preferred embodiment of the present invention and institute's application technology principle; In the disclosed technical scope of the present invention, any variation that the technician expected easily or replacement of being familiar with the present technique field all should be encompassed in protection scope of the present invention.
