Abstract

The utility model discloses a roller central hole inspection measuring tool. The roller central hole inspection measuring tool comprises a dial indicator and a measuring tool main body. The measuring tool main body has a cylindrical structure, a through hole is formed in the center of the measuring tool main body in the axial direction, the fixation bar of the dial indicator is arranged in the through hole and is fixedly connected with the measuring tool main body, and a groove is formed in the central position on the bottom of the measuring tool main body. According to the utility model, advantages of simple structure and easy operation are realized, the groove is arranged on the bottom of the measuring tool main body, so the good contact between the end face of the measuring tool and the end face of the roller is ensured, and the dial indicator is clamped and installed through a bush to make the fixation bar of the dial indicator bear bear an uniform force so as to ensure that the dial indicator will not be damaged in the clamping and installation process.

Description

Roller centre hole check measurer
Technical field
The utility model relates to measurer, relates in particular to a kind of roller centre hole check measurer.
Background technology
Now the society along with technology suddenly fly advance by leaps and bounds, various advanced persons' lathe meets the tendency.The running accuracy of lathe requires also more and more higher, really affects its precision 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, will directly affect the use of whole lathe.The particularly assembling of high-precision rolling bearing.
Want high-precision running in bearings at first to need the size of each parts of bearing itself is carried out maximum precision, in the assembling process of bearing roller and retainer, the degree of depth of bearing end center pit is to affect the accurately key factor of running of bearing, is very necessary to the detection of bearing roller depth of center hole therefore.
The utility model content
The technical matters that the utility model solves is: a kind of bearing roller center pit check measurer is provided, measures easily the degree of depth in roller centre hole.
For reaching this purpose, the utility model by the following technical solutions:
A kind of roller centre hole check measurer, comprise clock gauge and measurer main body, described measurer main body becomes cylindrical structure, and its central shaft is to being provided with through hole, the fixed bar of described clock gauge is arranged in the through hole and is fixedly connected with described measurer main body, and described measurer bottom part body center is provided with groove.
Further, be provided with lining in the described through hole, described lining is fixedly connected with the measurer main body, and the fixed bar of described clock gauge is fixedly connected with the measurer main body by lining.
Further, described lining adopts resilient material to make.
Further, vertical with the described center pit clamping bolt hole that is provided with on the described measurer main body.
The beneficial effects of the utility model are: simple in structure, easy to operately in the measurer bottom part body groove are set and guarantee measurer end face and roller end face good contact, and not damaged when making the stressed even assurance clock gauge clamping of clock gauge fixed bar by lining clamping clock gauge.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is roller centre hole inspected number lamps structure schematic diagram.
Fig. 2 is measurer agent structure schematic 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 the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
Such as Fig. 1, shown in 2, in the present embodiment, a kind of roller centre described in the utility model hole check measurer, it comprises measurer main body 2 and clock gauge 1, described measurer main body 2 is cylindrical structure, its center position axis to offer through hole 6, be provided with lining 3 in the described through hole 6, direction vertical with described through hole 6 on measurer main body 2 offers clamping bolt hole 7, described clamping bolt hole 7 is communicated with described through hole 6, the fixed bar 8 of described clock gauge 1 is fixedly mounted on the measurer main body 2 by lining 3, and described lining 3 adopts resilient material to make, and clamps by 3 pairs of clock gauges 1 of bolt extruding lining of clamping bolt hole 7 interior settings; Described 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 demonstrate reading at the clock gauge dial plate, 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 by 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, to guarantee that roller 5 end faces can effectively contact with measurer main body 2 lower surfaces, guarantee that measurement data is accurate.
What need statement is; above-mentioned embodiment only is preferred embodiment of the present utility model and institute's application technology principle; in technical scope disclosed in the utility model; the variation that any those skilled in the art of being familiar with easily expected or replacement all should be encompassed in the protection domain of the present utility model.
