Abstract
The utility model discloses a precise pivoting support hydraulic pressure detector which comprises a workbench; the workbench is fixedly provided with a pressure plate through a screwing bolt; horizontal cushion blocks with equal height corresponding to the pressure plate are placed on the workbench; a workpiece outer ring is clamped between the horizontal cushion blocks with equal height and the pressure plate; the workbench is also provided with a cylinder; the cylinder supports a workpiece inner ring; the cylinder is connected with an external hydraulic unit by an oil pipe; the hydraulic unit is connected with a hydraulic rod through the oil pipe; the hydraulic rod is a two-head cylinder, and the two ends thereof are respectively provided with a piston rod which extends out of the workbench; and the piston rod is further provided with a dial gauge. By arranging the dial gauge that is matched with hydraulic pressure, the precise pivoting support hydraulic pressure detector can detect multiple indexes such as form and position tolerance of axial clearances, form and position tolerance of radial clearances, end-surface run-out tolerance and the like, and has simple structure, high working efficiency and high precision.
Description
Technical field:
The utility model relates generally to the technical field of quality detection of component of machine product, relates in particular to a kind of micron order pivoting support hydraulic detection device with high precision quality requirements.
Background technology:
Pivoting support (Slewing Ring) is that plant equipment is rely and rotated and the base components of power transmission, be a kind of band gear ring and multiple eyelet, can bear the large size bearing of axial force, radial force and upsetting moment, its main body is to be made of inside and outside two circles, is provided with raceway and rolling body between two circles; According to the industry standard requirement, because it is comparatively loose that the regular grade pivoting support detects index, detection mode is many to be prized, intuitively measures with manpower, and for the micron order pivoting support with high precision quality requirements, because test item is a lot, very tight to the tolerance clearance index request especially, described detection mode manpower prizes and directly perceived the measurement, measured result is not calculated through accurate, and error is inaccurate greatly, then can not satisfy request for utilization.
The trial-production micron order pivoting support starting stage, there is not pick-up unit, on assembly bench, place 3 contour cushion blocks, to examine product liftings or lift to and fill up inner ring on the contour pad with 3 people, 3 dial gauges make zero, 3 people gently lift simultaneously inspection product and contour pad is changed fill up the outer ring then, allow the unsettled generation gravity that hangs down of inner ring, make 3 dial gauge numerical value changes, detect key index-end play form and position tolerance like this, though this kind method error reduces relatively, but want to lift workpiece twice, inefficiency, and only can only measure the end play form and position tolerance, and cannot measure, so can not satisfy strict request for utilization for the radial play form and position tolerance.
The utility model content:
The purpose of the novel usefulness of this reality is in order to remedy the deficiency of defectiveness, a kind of micron order pivoting support hydraulic detection device is provided, utilize hydraulic pressure and the dial gauge device that matches, can detect many indexs such as end play form and position tolerance, radial play form and position tolerance, face runout tolerance, and simple in structure, high efficiency, the degree of accuracy height.
The utility model is achieved through the following technical solutions:
A kind of micron order pivoting support hydraulic detection device, include worktable, by screwing bolt pressing plate is installed on the described worktable, be placed with the contour cushion block of the level corresponding on the described worktable with pressing plate, the outer ring of clamping pivoting support between described contour cushion block and the pressing plate, it is characterized in that: oil cylinder also is installed on the described worktable, described oil cylinder supports the inner ring of pivoting support, described oil cylinder is connected with external Hydraulic Station by oil pipe, described Hydraulic Station is connected with hydraulic stem by oil pipe, described hydraulic stem is the double end oil cylinder, and its two ends have piston rod to stretch out respectively, and described worktable also is provided with dial gauge outward.
Described a kind of micron order pivoting support hydraulic detection device is characterized in that: described contour cushion block and pressing plate can be uniformly distributed on the worktable for three groups or four groups.
Described a kind of micron order pivoting support hydraulic detection device is characterized in that: described oil cylinder and dial gauge are respectively three or four.
The utility model is wanted to cooperate by hydraulic means and dial gauge device, can detect ten many indexs such as end play form and position tolerance, radial play form and position tolerance, face runout tolerance, outer ring inner stopper runout tolerance, pitch circle runout tolerance, position of mounting hole degree tolerance, mounting hole reference circle tolerance, inner ring sealing strip axial location tolerance, unloaded resistance test.
The utility model is the pivoting support of the various models between the raceway central diameter φ 760-φ 1410mm to the suitable sensing range of inspection product.
The utility model has the advantages that:
The utility model utilizes hydraulic pressure and the dial gauge device that matches, and can detect many indexs such as end play form and position tolerance, radial play form and position tolerance, face runout tolerance, and simple in structure, high efficiency, the degree of accuracy height.

Embodiment:
A kind of micron order pivoting support hydraulic detection device, include worktable 1, by screwing bolt pressing plate 3 is installed on the worktable 1, be placed with the level contour cushion block 2 corresponding on the described worktable 1 with pressing plate 3, holding workpiece outer ring 4 between contour cushion block 2 and the pressing plate 3, oil cylinder 6 also is installed on the worktable 1, oil cylinder 6 supporting workpiece inner rings 5, oil cylinder 6 is connected with external Hydraulic Station 7 by oil pipe, Hydraulic Station 7 is connected with a plurality of hydraulic stems 9 by oil pipe, each hydraulic stem 9 is the double end oil cylinder, and its two ends have piston rod to stretch out respectively, the worktable 1 outer dial gauge 8 that also is provided with.
The concrete method that detects end play form and position tolerance and radial play form and position tolerance:
(1), detect end play form and position tolerance method:
So-called end play form and position tolerance, when detecting the pivoting support horizontal positioned exactly, the difference gap under its inside and outside circle state of nature and the oppression state.Concrete operations are: screw pressing plate 3 and push down pivoting support outer ring 4, on pivoting support inner ring 5, place 3 dial gauges 8, every rough alignment oil cylinder 6, dial gauge 8 pointers contact outer ring 4 upper surfaces and make zero, start Hydraulic Station 7 then and give oil cylinder 6 pressurizations, record 3 of dial gauge 8 readings; To be less than or equal to tolerance index person qualified for end play for maximum reading in 3 readings.
(2), detect radial play form and position tolerance method:
So-called radial play form and position tolerance detects the difference gap of the inside and outside circle of pivoting support when a certain side is pushed exactly.Concrete operations are: screw pressing plate 3 and push down outer ring 4, on inner ring 5, place 3 dial gauges 8, pointer contacts outer ring 4 medial surfaces and makes zero, the piston rod that stretches out with the two ends of hydraulic stem 9 withstands the inboard, outer ring at dial gauge 8 places respectively then, the piston rod that stretches out with the two ends of another hydraulic stem 9 withstands the inner ring inboard at dial gauge 8 places respectively again, and fuel feeding pressurization records 3 of dial gauge 8 readings three times; To be less than or equal to tolerance index person qualified for radial play for maximum reading in 3 readings.
