Description
Technical field
The utility model relates to technical field of mechanical transmission, particularly relates to a kind of measuring instrument for projection of angular contact ball bearing.
Background technology
The high-precision bearing used in modern precision instrument and equipment, most angular contact ball bearing using pairing.Angular contact ball bearing can bear radial load and axial load simultaneously.Can work at higher rotational speeds.Contact angle is larger, and axial carrying capacity is higher.High precision and high-speed bearing get 15 degree of contact angles usually.Under responsive to axial force, contact angle can increase.And measured angular contact ball bearing end face bulge quantity determines that can two covers or many cover bearings form the crucial option of duplex or multi-joint bearing, it not only affects precision, the rigidity of instrument and equipment.And directly affect the serviceable life of bearing.Thus the end face bulge quantity accurately measuring angular contact ball bearing has a very important role.
Utility model content
To the present situation of above-mentioned prior art, technical problem to be solved in the utility model is that providing a kind of measures the measuring instrument for projection of angular contact ball bearing that efficiency is high, accuracy is high.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of measuring instrument for projection of angular contact ball bearing, comprise base, described base is provided with column, this column upper end is provided with instrument dial framework, described base is provided with connected measurement mechanism and leverage, described measurement mechanism comprises push rod and inductance probe, described push rod upper end is provided with pallet, described inductance probe lower end is provided with surveys lid and gland, workpiece calibration place is provided with between described gland and pallet, described pallet side is provided with hand handle, is provided with linear bearing outside described push rod.
Further, described leverage comprises lever.
Further, described lever one end is provided with lever support, and this lever support relies on revolving shaft bearing to contact with push rod, for applying pretightning force to bearing.
Further, described lever is provided with load block, makes lever can align applying load.
Further, be provided with tip-lever support outside described linear bearing, for installing linear bearing, fixed mandril makes push rod accurately move up and down.
Compared with prior art, the utility model has the advantage of: the utility model by arranging measurement mechanism, for measured angular contact ball bearing bulge quantity, by arranging leverage, for applying pretightning force to bearing, the utility model is reasonable in design, can large-scale promotion.
Accompanying drawing explanation
Fig. 1 is a kind of measuring instrument for projection of angular contact ball bearing structural representation of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of measuring instrument for projection of angular contact ball bearing, comprise base 1, described base 1 is provided with column 13, this column 13 upper end is provided with instrument dial framework 12, described base 1 is provided with connected measurement mechanism and leverage, described measurement mechanism comprises push rod 2 and inductance probe 11, described push rod 2 upper end is provided with pallet 5, described inductance probe 11 lower end is provided with surveys lid 10 and gland 9, the centre of described survey lid 10 is provided with measuring head 17, described pallet 5 side is provided with hand 6, linear bearing 4 is provided with outside described push rod 2, described leverage comprises lever 15, described lever 15 one end is provided with lever support 16, the end of this lever support 16 contacts with push rod 2, for applying pretightning force to bearing, described lever 15 is provided with load block 14, make the adjustable applying load of lever 15, tip-lever support 3 is provided with outside described linear bearing 4, for installing linear bearing 4, fixed mandril 2, push rod 2 can accurately be gone up, lower movement.
Angular contact ball bearing inner ring surveying work principle illustrates:
The measuring process of measuring instrument is carried out in two steps, first inductance probe 11 is aimed at and to survey in lid 10 in the heart, first load bearing standard ring, rotate hand 6 several times to zero, then standard ring is taken off, load bearing 7, load gland 9 subsequently and survey lid 10, and lock gland 9, inductance probe 11 to be aimed at survey in lid 10 in the heart, then the preloading that push rod 2 pairs of inner rings are specified by lever drive applying standard is made, rotate hand subsequently 6, inner ring is constantly made to rotate 90 ° or 120 °, by the numerical value of the end face of inner ring several times bulge quantity recorded, get its mean value, this mean value and the difference of standard ring to the numerical value of zero are the inner ring end face bulge quantity of the bearing 7 recorded, because load moves hand 6, by the ratio of gear of lever 1: 1, load is added on inner ring, this load should give with the inner ring that specifies in standard that to add load equal.
Compared with prior art, the utility model has the advantage of: the utility model by arranging measurement mechanism, for measured angular contact ball bearing bulge quantity, by arranging leverage, for giving push rod clamping force upwards, the utility model is reasonable in design, can large-scale promotion.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in previous embodiment, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment technical scheme of the utility model.
