Description

A kind of electric motor end cap dead eye form and position tolerance measuring instrument
Technical field
The utility model relates to a kind of testing tool, particularly a kind of electric motor end cap dead eye form and position tolerance measuring instrument.
Background technology
Because the dead eye on the high 63mm ~ 160mm electric motor end cap of center does not connect completely, general detection method is difficult to dial gauge to probe in dead eye and detect accurately, so electric motor end cap removes and is just difficult to detect the diameter run-out of dead eye to seam external diameter from lathe after machining.
Some detection methods are to carry out on high precision horizontal lathe, when work, by the dead eye of electric motor end cap outwardly, the claw of high precision Horizontal type lathe chuck is stuck on the seam of electric motor end cap, and the gauge head of dial gauge is against to electric motor end cap dead eye place, rotating chuck, observes beating of dial gauge indicator.This detection method is consuming time longer, therefore can not check each electric motor end cap, and can only inspect by random samples, detection efficiency is low; In addition, because electric motor end cap is Thin-shell Part, easily deform, claw is stuck on electric motor end cap seam, and Ka Lihui causes seam and a certain amount of distortion of dead eye, adds the error of horizontal lathe spindle, make the parameter that detects inaccurate, produce wrong direction, caused that this scraps do not scrap, should not scrap but scrapped, will cause like this significant wastage of material and resource.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple in structure, detection efficiency is high, testing result electric motor end cap dead eye form and position tolerance measuring instrument accurately.
The utility model solves the technical scheme that its technical matters adopts:
A kind of electric motor end cap dead eye form and position tolerance measuring instrument, comprise base, the rigid support plate that is provided with dial indicator bracket on described base and is inclined relative to horizontal, the adjustable dial gauge in position is installed on dial indicator bracket, rigid support plate away from a side of dial indicator bracket be provided with more than two position adjustable, for supporting and prop up the locating piece of seam of electric motor end cap, described rigid support plate is provided with to be convenient to dial gauge and to stretch into the through hole of measuring in the dead eye on electric motor end cap.
In the utility model, one end that described locating piece is used for the seam that supports and prop up electric motor end cap is set to arc.
In the utility model, on described locating piece, be provided with chute, chute place is provided with bolt, and described bolt thread is connected in rigid support plate.
In the utility model, described rigid support plate is hinged on base by bearing pin.
In the utility model, described base comprises pedestal and is arranged on the bearing on pedestal, and described rigid support plate is hinged on bearing by bearing pin.
In the utility model, on described base, be provided with the gag lever post of restriction rigid support plate rotational travel.
In the utility model, described dial gauge is lever indicator.
The beneficial effects of the utility model are: the utility model carrys out supporting motor end cap by plural locating piece, and it is all very convenient quick that therefore electric motor end cap is installed to location in rigid support plate and in rigid support plate.After the position of locating piece is adjusted, locating piece can prop up the outside of the seam of electric motor end cap, and while preventing from measuring, electric motor end cap rocks and affects measurement result, to ensure the accuracy of measurement result.The through hole of dial gauge rigid support plate extend in dead eye to be detected, electric rotating machine end cap, can obtain the form and position tolerance such as diameter run-out, right alignment data by beating of dial gauge, measures simple and convenient, measurement efficiency is high, and measurement result is also more accurate.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the front view while being placed with electric motor end cap on the utility model;
Fig. 2 is left view of the present utility model.
Embodiment
As shown in Fig. 1 ~ Fig. 2, a kind of electric motor end cap dead eye form and position tolerance measuring instrument, comprise base 1, the rigid support plate 3 that is provided with dial indicator bracket 2 on described base 1 and is inclined relative to horizontal, the adjustable dial gauge in position 4 is installed on dial indicator bracket 2, dial gauge 4 can slide and adjust height on dial indicator bracket 2, so that detect the form and position tolerance of dead eye.Described rigid support plate 3 is provided with the gauge head of being convenient to dial gauge 4 and stretches into the through hole 31 of measuring in the dead eye on electric motor end cap 301.As preferably, described dial gauge 4 is lever indicator.Lever indicator volume is little, lightweight, and gauge head can change direction, uses easily, can measure general measure utensil and be difficult to the position of detecting.
Rigid support plate 3 away from a side of dial indicator bracket 2 be provided with more than two position adjustable, for supporting and prop up the locating piece 5 of seam of electric motor end cap 301, as preferably, described locating piece 5 is set to arc for one end of the seam that supports and prop up electric motor end cap 301, locating piece 5 is just smaller with the contact area of the seam of electric motor end cap 301 like this, can reduce the impact of the measurement result on dial gauge 4 as far as possible.In addition, on described locating piece 5, be provided with chute 51, chute 51 places are provided with bolt 52, and described bolt 52 is threaded in rigid support plate 3.Need to adjust the position of locating piece 5 time, looser a bolt 52, to be positioned 5 slide into desired position after, then tight a bolt 52, just locating piece 5 can be fixed on to desired position.
In addition, in the utility model, the quantity of locating piece 5 is preferably three, wherein two under, one upper.Under two locating pieces 5 be mainly used for the seam of supporting motor end cap 301 rapidly, mainly play aiding support at a upper locating piece 5, prevent that rotary electric machine end cap 301 from rocking while rotation and affecting the accuracy of measurement result.
Three locating pieces 5 contact with the seam of electric motor end cap 301, and with supporting motor end cap 301, it is all very convenient quick that therefore electric motor end cap 301 is installed to location in rigid support plate 3 and in rigid support plate 3.After bolt 52 lockings are adjusted and used in the position of locating piece 5, locating piece 5 props up the outside of the seam of electric motor end cap 301, and while preventing from measuring, electric motor end cap 301 rocks and affects measurement result, to ensure the accuracy of measurement result.Dial gauge 4 extend in dead eye and with electric motor end cap 301 and contacts at the inwall at dead eye place from the through hole 31 in rigid support plate 3, electric rotating machine end cap 301, can obtain the form and position tolerance such as diameter run-out, right alignment data by the jerk value of dial gauge 4, measure simple and convenient, measurement efficiency is high, and measurement result is also more accurate.
Further, described rigid support plate 3 is hinged on base 1 by bearing pin 30.Described base 1 comprises pedestal 11 and is arranged on the bearing 12 on pedestal 11, described rigid support plate 3 is hinged on bearing 12 by bearing pin 30, therefore can reasonably regulate the gradient of rigid support plate 3, so that electric motor end cap 301 can not fall down after being placed in rigid support plate 3, be also not easy to rock.
Further, on described base 1, be provided with the gag lever post 13 of restriction rigid support plate 3 rotational travel.After electric motor end cap 301 is placed in rigid support plate 3, under Action of Gravity Field, may make rigid support plate 3 rotate, therefore need to arrange gag lever post 13, to prevent that rigid support plate 3 rotational travel are excessive and electric motor end cap 301 is dropped.
