Abstract
The utility model discloses a bearing internal diameter automatic measuring device. The bearing internal diameter automatic measuring device comprises a fixed plate, a movable plate, a drive device, a return spring, an inductance gauge head, a PLC controller and contact heads. The fixed plate and the movable plate are connected through a hinge. One end of the fixed plate and one end of the movable plate positioned at the same side of the hinge are respectively connected with the contact heads. The other end of the movable plate is connected with the return spring, and moves around the hinge under the driving of the drive device. The other end of the fixed plate is equipped with the inductance gauge head. The inductance gauge head is connected with the PLC controller. The bearing internal diameter automatic measuring device can satisfy automation production, and the hinge connection and wear resistant ceramic balls are formed through a spring leaf, so the bearing internal diameter automatic measuring device has higher precision and makes the measured bearing internal diameter data more stable.
Description
Technical field
The utility model belongs to the plant equipment field, relates in particular to the measuring equipment of bearing bore diameter.
Background technology
Bearing has a wide range of applications at industrial circle, and whether qualified, like bearing bore diameter if need test its mass parameter after the Production of bearing.The most hand dippings that adopt of the measurement of bearing bore diameter at present do not satisfy automated production like this, and measurement data are stable inadequately.
Summary of the invention
Goal of the invention: to the problem and shortage of above-mentioned existing existence, the purpose of the utility model provides a kind of bearing bore diameter self-operated measuring unit, thereby satisfies automated production, and measurement data is stable.
Technical scheme: for realizing the foregoing invention purpose; The utility model adopts following technical scheme: a kind of bearing bore diameter self-operated measuring unit; Comprise fixed head, portable plate, drive unit, back-moving spring, inductance probe, PLC controller and contact, said fixed head and portable plate adopt hinge to be connected, and the end that they are in the hinge homonymy is connected with contact respectively; The other end of said portable plate is connected with back-moving spring; And by drive device drives around hinge movement, the other end of said fixed head is installed inductance probe, this inductance side head is connected with said PLC controller.
The initial state of this device is, fixed head is fixed, and the drive device drives portable plate makes the contact on the portable plate draw in toward the fixed head upper contact head around hinge through; During work, drive unit quits work, portable plate under the pulling force of back-moving spring in the other direction around hinge through; Thereby the portable plate upper contact head is outwards opened and touch bearing inner wall; Portable plate can contact with the sense of touch gauge head simultaneously, makes this inductance contact produce displacement, and sends the PLC controller to measuring the floatingpotential data of coming out; The PLC controller converts potential data to numerical data and on screen, exports, and finally accomplishes the DATA REASONING of bearing bore diameter.
As preferably; The hinge of said connection fixed head and portable plate comprises spring leaf and pressing plate; These spring leaf two ends are fixedly mounted on fixed head and the portable plate through pressing plate respectively, make portable plate do hinge movement around spring leaf, and this spring leaf is processed by the thick steel spring plate of 0.3～0.8mm.Because spring leaf elasticity toughness is relatively good, its elastic deformation can be eliminated the swing gap of portable plate, and is more accurate than general linkage.
As preferably, the contact on said fixed head and the portable plate is provided with three altogether and is the wearable ceramic balls that isosceles triangle is arranged, thereby avoids the juxtaposition metamorphose of contact to influence measuring accuracy.
Said drive unit adopts cylinder, and the push rod of this cylinder passes fixed head over against the portable plate setting.
Beneficial effect: compared with prior art, the utlity model has following advantage: satisfy automated production, and form hinge through spring leaf and connect and wearable ceramic ball, thereby have higher precision, make measure the bearing bore diameter data more stable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
As shown in Figure 1; A kind of bearing bore diameter self-operated measuring unit; Comprise fixed head 1, portable plate 2, contact 6, pressing plate 8, spring leaf 7, drive cylinder 3, back-moving spring 4, pen type inductance probe 5 and PLC controller; Said fixed head 1 is fixed, establishes a boss on fixed head 1 and the portable plate 2 same horizontal levels, and a side that fixed head 1 and portable plate 2 is provided with boss is relative; And will lay on it by the spring leaf 7 that the thick steel spring plate of 0.3～0.8mm is processed; Respectively the two ends of spring leaf 7 are fixed on fixed head 1 and the portable plate 2 through pressing plate 8 then, thereby make portable plate 2 to do bar thick stick formula hinge movement around spring leaf 7, said fixed head 1 is connected upper contact head 6 with portable plate 2 respectively at an end of spring leaf 7 homonymies; Simultaneously the push rod of said driving cylinder 3 passes fixed head 1 and over against portable plate 2 other ends; Thereby push rod can promote portable plate 2 around spring leaf 7 rotations when driving cylinder 3 work; This end of fixed head 1 is provided with pen type inductance contact 6 in addition, and portable plate 2 can touch this pen type inductance contact 6 when rotating, when inductance contact 6 produces displacement; Can the floatingpotential data of trace be amplified the accurate PLC controller that sends to again, the PLC controller converts potential data to numerical data again; Said back-moving spring 4 is connected with portable plate 2, on two contacts 6, is provided with three altogether in addition and is the wearable ceramic ball 9 of isosceles triangle.
Work front shoe 1 is fixed; Driving cylinder 3 on the fixed head 1 is released and is pushed portable plate 2; Because the elasticity toughness of spring leaf 7 is all relatively good, spring leaf 7 elastic deformations and swing gap that can the elimination activity, all also more accurate than general linkage; Portable plate 2 is around spring leaf 7 swings, and fixed head 1 upper contact head 6 draws in toward portable plate 2 upper contact heads 6 directions.During work, driving cylinder 3 withdrawals on the fixed head 1, back-moving spring 4 pulling portable plates 2; Portable plate 2 is around spring leaf 7 swings; Contact 6 on the portable plate 2 outwards opens and touches the wall of bearing bore diameter, and portable plate 2 can contact with pen type inductance probe 5 simultaneously, and pen type inductance probe 5 produces displacement; Send the PLC controller to measuring the floatingpotential data of coming out, the PLC controller converts potential data to numerical data through screen output again.Measurement data is accomplished like this.When returning original position, drive cylinder 3 releases and push portable plate 2, portable plate 2 is around spring leaf 7 swings, and the contact 6 on the portable plate 2 inwardly draws in.Whole like this device all is reset to initial position, realizes measuring automatically purpose.
