Abstract
The invention relates to a measuring instrument for radial internal clearance of a medium-large rolling bearing. The measuring instrument is characterized by comprising a measuring table (2) perpendicular to the ground, wherein a locking device (5) is mounted on the measuring table (2), so that the inner ring of the bearing (4) to be measured can be locked or loosened; a bearing adjustment and location device (6) is mounted below the locking device (5), so that the outer ring of the bearing (4) to be measured can be supported, and the height of the outer ring of the bearing (4) to be measured above the ground can be adjusted; a dial gauge location device (1) is mounted above the locking device (5); and a dial gauge (3) is mounted on the dial gauge location device (1). After the measuring instrument is adopted, operators can accurately measure and control bearing radial internal clearance parameters; the inaccuracy of the traditional filler gauge measuring method is avoided; the product quality and the production efficiency are improved; the labor intensity of the operators is reduced; and the market competitiveness of a bearing product is improved.
Description
Technical field
The present invention relates to a kind of medium-and-large-sized rolling bearing radial play measuring instrument.
Background technology
At present, still there is no at home special bearing end-play surveying instrument on market, usually the measuring method that adopts is still that clearance gauge is measured, because clearance gauge is measured by artificially controlling, therefore, operating personnel are measuring the larger difference of existence on gimmick and operating experience, and the measuring error of generation is also uncontrollable.
Summary of the invention
The purpose of this invention is to provide a kind of medium-and-large-sized rolling bearing radial play measuring instrument, can measure accurately medium-and-large-sized rolling bearing end-play parameter.
A kind of medium-and-large-sized rolling bearing radial play measuring instrument, its special feature is: comprise measuring table perpendicular to the ground, on this measuring table, locking device is installed, thereby can lock or unclamp bearing inner race to be measured, bearing is installed adjusts locating device below this locking device, thereby can hold up bearing outer ring to be measured and adjust bearing outer ring terrain clearance to be measured; The dial gauge locating device is installed above aforementioned locking device, on this dial gauge locating device, dial gauge is installed.
Wherein locking device comprises threaded rod, and an end of this threaded rod is fixed on measuring table and its other end passes pressing plate and set nut successively, and threaded rod and measuring table Surface Vertical.
Its centre bearer is adjusted locating device and is comprised and be located at the vertical groove groove vertical with second of first on measuring table, also comprise the roller that passes the first vertical groove, one end of this roller is connected with roller and its other end is connected with V-block, and also hinged with an end of handle after this roller passes from V-block, and the middle part of this handle is hinged in the second vertical groove.
Wherein the dial gauge locating device comprises guide plate, and this guide plate is arranged in the T-shaped groove of measuring table upper end, thereby can move along T-shaped groove, and this guide plate also is connected with dial gauge by sleeve.
Wherein the gauge outfit of dial gauge is towards bearing outer ring to be measured.
The invention provides a kind of medium-and-large-sized rolling bearing radial play measuring instrument, through probationary certificate, after adopting this measuring instrument, operating personnel can measure, control the bearing end-play parameter accurately, avoided the inaccuracy of traditional clearance gauge measuring method, product quality and production efficiency have also been improved simultaneously, reduce operating personnel's labour intensity, strengthened the market competitiveness of bearing products.
Description of drawings
Accompanying drawing 1 is the structural representation in front of the present invention;
Accompanying drawing 2 is the structural representation of side of the present invention.
Embodiment
As shown in Figure 1, 2, the present invention is a kind of medium-and-large-sized rolling bearing radial play measuring instrument, comprise measuring table perpendicular to the ground 2, on this measuring table 2, locking device 5 is installed, thereby can lock or unclamp bearing 4 inner rings to be measured, bearing is installed adjusts locating device 6 below this locking device 5, thereby can hold up bearing to be measured 4 outer rings and adjust bearing 4 outer ring terrain clearances to be measured; Above aforementioned locking device 5, dial gauge locating device 1 is installed, on this dial gauge locating device 1, dial gauge 3 is installed.
Wherein locking device 5 comprises threaded rod, and an end of this threaded rod is fixed on measuring table 2 and its other end passes pressing plate and set nut successively, and threaded rod and measuring table 2 Surface Verticals.Bearing is adjusted locating device 6 and is comprised and be located at the vertical groove of first on measuring table 2 groove vertical with second, also comprise the roller that passes the first vertical groove, one end of this roller is connected with roller and its other end is connected with V-block, and also hinged with an end of handle 7 after this roller passes from V-block, and the middle part of this handle 7 is hinged in the second vertical groove, and the concrete articulated position on this second vertical groove can be adjusted as required.When downward depression of handle 7, according to lever principle, thereby V-block is lifted and holds up bearing to be measured 4 outer rings.
Dial gauge locating device 1 comprises guide plate, and this guide plate is arranged in the T-shaped groove of measuring table 2 upper ends, thereby can move along T-shaped groove, and this guide plate also is connected with dial gauge by sleeve.The gauge outfit of dial gauge 3 is towards bearing to be measured 4 outer rings in addition.
Principle of work of the present invention and using method are:
At first the outer ring of bearing 4 to be measured being placed in bearing adjusts on locating device 6, apply a power downwards on the handle 7 of this device, at this moment the V-block of these handle 7 other ends is with vertical upper act of bearing 4 to be measured, when bearing 4 to be measured arrives assigned address, operation locking device 5, be that the rotational lock nut compresses inner ring by pressing plate, the inner ring of bearing 4 to be measured is locked on measuring table 2.
Then unclamp bearing and adjust the handle 7 of locating device 6, make the outer ring free-falling of bearing 4 to be measured, adjust dial gauge locating device 1 this moment, the gauge outfit of dial gauge 3 is abutted against on the outer ring of bearing 4 to be measured and play the table zeroing, then operate bearing and adjust the handle 7 of locating device 6, hold up bearing 4 to be measured bottom outer ring and it is close to fully on inner ring, read the reading of dial gauge 3 by operating personnel, can learn the play of bearing 4 to be measured.
