In addition, have now in the used sensor unit of instrument for measuring bearings, adopt the drum type brake spring structure, not only volume is big, and in test process resonance effect takes place easily, influences the bearing test mass.
[summary of the invention]
The object of the present invention is to provide a kind of instrument for measuring bearings that has vertical spindle transmission and upper and lower materials device, can be used for the vibration values of bearing measuring taper roll bearing, angular contact ball bearing, deep groove ball bearing.
The objective of the invention is to be achieved through the following technical solutions.
A kind of instrument for measuring bearings, comprise body, drive system, thrust device, bearing measuring device, lubricating system and electronic box, it is characterized in that on the platform of body of said thrust device both sides upper and lower materials device being installed, feeding device is made up of last flitch on the mounting platform and the scraping wings that is fixed on flitch one side stand; Blanking device is made up of the blanking road that is arranged on the platform.Carry flitch and be arranged between the upper and lower materials device, move up and down by the thrust device drive.
In order to make the bearing that this vialog can the bearing measuring different inner diameters, scraping wings one side on the above-mentioned feeding device medium-height trestle is provided with the adjustable location-plate of scraping wings, is used for adjusting and fixing scraping wings position.
For fear of sensor resonance effect taking place in test process, leaf spring is installed in this sensor unit, to substitute drum type brake spring structure in the existing sensor unit, improves this vialog measuring accuracy.
Consider the segregative characteristics of overcoat in the taper roll bearing, instrument for measuring bearings provided by the present invention adopts vertical spindle and upper and lower materials device, and improved acceleration sensor structure used for a long time, thereby solved taper roll bearing vibration values bearing measuring problem, improved this vialog measuring accuracy.Simultaneously, utilize this vialog also can take into account the vibration values of bearing measuring angular contact ball bearing, deep groove ball bearing.This vialog entire machine design uniqueness, compact conformation, easy to operate, and be provided with monitoring and definite value indicating device, by sound or the definite value pilot lamp that loudspeaker sends, also can judge and evaluate the quality of bearing.
[description of drawings]
Fig. 1 is an embodiment of the invention complete machine structure synoptic diagram;
Introduce the present invention in detail below in conjunction with the drawings and specific embodiments.
[specific embodiment] this vialog structure is seen shown in Figure 1, dress drive motor 13, lube oil pump 11, fuel tank 12 and control circuit thereof in its body 1 comprises, and body 1 is provided with platform 3, and it is the mounting base of complete machine.Drive system 2 comprises upper and lower vertical spindle and detachable mandrel 21, and it is to drive the power source that bearing inner race rotates, and also is the main part of instrument.Thrust device 6 comprises column 64, thrust slide 63, big handwheel 62, thrust spring 65 and thrust disc 61, and its effect is that bearing is applied axial load.Feeding device 9 comprises scraping wings 91, location-plate 92, goes up flitch 93 and support 94 thereof.Scraping wings 91 1 sides on the support 94 are provided with to be adjusted and the fixing adjustable location-plate 92 of scraping wings 91 positions, and support 94 is provided with locating shaft 921, and location-plate 92 is provided with moving slider 922.Scraping wings 91 is provided with bearing 911, and this bearing 911 is connected location fork 914 by axle 912 with adjustment nail 913, and moving handle 915 is fixed on the scraping wings 91.Blanking device 4 comprises the blanking road that is arranged on the platform 3.Carrying flitch 5 is thrust disc 61 belows that are horizontally set on thrust device 6 by screw rod 51, and the last crossbearer 52 of screw rod 51 is fixed on the coupling shaft of thrust disc 61, carries flitch 5 and is moved up and down by thrust device 6 drives.Bearing measuring device 8 comprises horizontal slide plate 81 and vertical slide 82 and adjustment handwheel 83, pendulum plate 84, sensor unit 85, is the device that converts vibration signal to electric signal and be transported to the bearing measuring amplifier.The sensor unit 85 of bearing measuring device 8 comprises contact 851 and vibration-sensing rod 852, is fixed on the leaf spring 854 by connecting support 853; Pendulum plate 84 front ends are equipped with sensor unit 85, the rear end is assemblied in vertical slide 82 by coupling shaft 841.Lubricating system comprises oil pump 11, fuel tank 12 and pipeline, and main shaft is carried lubricating oil.Electronic box 7 comprises electrical equipments such as built-in prime amplifier, bandpass amplifier, is the electric signal process that sensor transmits is handled the assembly that finally represents to user's vibration values.Loudspeaker or definite value pilot lamp are housed in the electronic box 7.Tone and the volume of utilizing loudspeaker to send, the operator can judge the reason that influences bear vibration: the spot and the scuffing on dust particle or raceway and rolling body surface.The vibration signal amplitude that these factors cause is big and the time is very short or take place at random, even the instrument indication value reaction is not come out.But loudspeaker but can send tangible sound and can distinguish out.When using this jewel to measure bearing vibration value, when only doing certified products and unacceptable product sorting, use " definite value pilot lamp " on this instrument electronic box more convenient, and can improve detection efficiency not needing to do the accurate values bearing measuring.
