Abstract
The invention relates to the technical field of mechanical part measuring devices, and in particular to a symmetry degree measuring device for a shaft keyway. The symmetry degree measuring device for the shaft keyway comprises a chassis, a stand revolved body column arranged on the chassis and a measuring device arranged in a screw hole on the top of the revolved body stand column, wherein the measuring device comprises an adjusting screw capable of moving in the screw hole, a lever indicator is arranged at the end part of the adjusting screw. The symmetry degree measuring device for the shaft keyway is simple and convenient in measuring process and high in measuring accuracy.
Description
Technical field
The present invention relates to machine parts measurement device technique field, particularly relate to key-groove symmetry tester on axle.
Background technology
Keyway processes a groove matched with key on axle or in hole, is used for fitting key, with transmitting torque; During the keyway that at present precision is higher in milling or mill axle, keyway generally has symmetry requirement, but due to the restriction of shape shaft structure, when measuring keyway symmetry on axle, measure comparatively difficulty, and measuring accuracy is not high, affects product quality.
Summary of the invention
The object of this invention is to provide a kind of measuring process easy, and key-groove symmetry tester on the high axle of measuring accuracy.
Technical scheme of the present invention is as follows:
Key-groove symmetry tester on axle, comprises chassis, the solid of revolution column that chassis is arranged, and is provided with measurement mechanism in the screw at solid of revolution column top; Described measurement mechanism comprises can the adjusting screw(rod) of movement in screw, and this adjusting screw(rod) end is provided with lever indicator.
Described solid of revolution column end face is provided with the through hole being communicated with screw.By screwing in hold-down bolt in through hole, after being convenient to regulate adjusting screw(rod) position, adjusting screw(rod) is locked.
Described adjusting screw(rod) right-hand member is provided with dovetail groove; Described lever indicator and adjusting screw(rod) contact jaw be provided with dovetail groove with the use of some flanges.The position of dovetail groove truck dead lever dial gauge is inserted by flange, thus the upper-lower height of adjustment (adjusting) lever dial gauge, to make, when measuring, lever indicator to be adjusted to suitable position.
On described axle, key-groove symmetry tester also comprises " L " shape supporter supporting workpiece.By " L " shape support body supports measured axis, improve accuracy of detection.
The workplace of described lever indicator measuring head is coated with and is coated with one deck titanium nitride layer, improve the wearing quality of this measuring head.
The invention has the beneficial effects as follows: by solid of revolution upright supports measurement mechanism, be convenient to measure; Can be moved forward and backward in screw by adjusting screw(rod), thus the front and back position of the lever indicator of adjusting screw(rod) end, make the measuring staff of lever indicator better contact measured axis, improve accuracy of detection; The symmetry of keyway on axle is measured by lever indicator; By " L " shape support body supports measured axis.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
Fig. 2 is side structure schematic diagram of the present invention;
In accompanying drawing, 1 is chassis, and 2 is solid of revolution column, and 3 is screw, and 4 is adjusting screw(rod), and 5 is lever indicator, and 6 is through hole, and 8 is flange, and 9 is " L " shape supporter, and 10 is measured axis, and 11 is iron block.
Embodiment
Shown in Fig. 1-Fig. 2, key-groove symmetry tester on axle, comprises chassis 1, and the solid of revolution column 2 that chassis is arranged is provided with measurement mechanism in the screw at solid of revolution column top; Described measurement mechanism comprises can the adjusting screw(rod) 4 of movement in screw 3, and this adjusting screw(rod) end is provided with lever indicator 5; On described axle, key-groove symmetry tester also comprises " L " shape supporter 9 supporting workpiece.
By solid of revolution upright supports measurement mechanism, can be moved forward and backward in screw by adjusting screw(rod), thus the front and back position of the lever indicator of adjusting screw(rod) end, make the measuring staff of lever indicator better contact measured axis; The symmetry of keyway on axle is measured by lever indicator; By " L " shape support body supports measured axis 10.
During measurement, pin the chassis below solid of revolution column, and carry out back rotation along its workpiece bus side, and write down the minimum value that lever indicator measures, then again solid of revolution column is placed on the opposite side bus of workpiece, measures with method, find out the minimum value of opposite side with lever indicator; Finally according to difference both workpiece keyway symmetry errors of lever indicator twice measurement.
Preferably, described solid of revolution column end face is provided with the through hole 6 being communicated with screw.By screwing in hold-down bolt in through hole, after being convenient to regulate adjusting screw(rod) position, adjusting screw(rod) is locked.
Preferably, described adjusting screw(rod) right-hand member is provided with dovetail groove; Described lever indicator and adjusting screw(rod) contact jaw be provided with dovetail groove with the use of some flanges 8.The position of dovetail groove truck dead lever dial gauge is inserted by flange, thus the upper-lower height of adjustment (adjusting) lever dial gauge, to make, when measuring, lever indicator to be adjusted to suitable position.
Preferably, described undersurface of bottom disc is embedded with iron block 11.By arranging iron block in chassis, increase the weight on chassis, when avoiding measuring, chassis is rocked, and causes measuring error.
Preferably, the workplace of described lever indicator measuring head is coated with and is coated with one deck titanium nitride layer, improve the wearing quality of this measuring head, make improve more than three times its serviceable life.
Preferably, described titanium nitride layer thickness is 1.5mm.Ensure wearing quality, ensure the sensitivity of measuring head simultaneously.
Preferably, described " L " shape supporting body surface is coated with and is coated with one deck titanium nitride layer, improves the wearing quality of this " L " shape supporter, makes improve more than three times its serviceable life.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
