Abstract
The invention relates to the technical field of measuring equipment, in particular to inner cavity planeness measuring equipment. A reference block can be embedded in an inner cavity. A positioning block is arranged above the reference block. A dial indicator penetrates through the reference block. At least three stabilizer blades are arranged on the bottom surface of the reference block. At least three rows of through holes are formed in the reference block. A conical measuring head is in threaded connection with the bottom of a measuring bar of the dial indicator. The inner cavity planeness measuring equipment can be used for measuring the planeness of the bottom surface of an inner cavity conveniently, and is high in measurement accuracy.
Description
Technical field
The present invention relates to measurement mechanism technical field, particularly relate to inner chamber flatness inspection devices.
Background technology
Part is the single product that can not break in machinery, is the underlying dimension of machine, is also the elementary cell in machine-building process; Current design of part is more and more diversified, wherein to the part with semiclosed inner chamber, due to the restriction of its structure, measures comparatively difficulty to this inner cavity of component soffit plane degree.
Summary of the invention
The object of this invention is to provide one to be convenient to measure inner chamber soffit plane degree, and the inner chamber flatness inspection devices that measuring accuracy is high.
Technical scheme of the present invention is as follows:
Inner chamber flatness inspection devices, comprises the reference block that can embed inner chamber, is arranged on the locating piece above base block, and runs through the dial gauge of locating piece; Described reference block bottom surface is at least provided with three legs, and base block is provided with three exhausting holes; Described dial gauge measuring staff bottom thread is connected with taper gauge head.
Described locating piece side wall surface is provided with mounting hole, is provided with the bolt of fixing dial gauge in this mounting hole.
Described locating piece faying face is embedded with magnet, and described base block faying face surface is laid with metal iron layer.
Described taper gauge head bottom is provided with steel ball.
The invention has the beneficial effects as follows: because reference block is consistent with cavity shape, being convenient to reference block to put into workpiece lumen when measuring; And locating piece is in order to the support to dial gauge; Arrange leg in order to support reference block in reference block bottom surface further, and in base block, arrange three exhausting holes, when reference block is placed in inner chamber, the position different at inner chamber is measured, thus adopts relative measurement method, realizes the measurement to inner chamber flatness.
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 base block structural representation of the present invention;
In accompanying drawing, 1 is reference block, and 2 is locating piece, and 3 is dial gauge, and 4 is leg, and 5 is through hole, and 6 is measuring staff, and 7 is taper gauge head, and 8 is mounting hole, and 9 is bolt, and 10 is magnet, and 11 is metal iron layer, and 12 is steel ball, and 14 is pushbutton switch, and 15 is small electric bulb.
Embodiment
Embodiment 1
Shown in Fig. 1-Fig. 2, inner chamber flatness inspection devices, comprises the reference block 1 that can embed inner chamber, is arranged on the locating piece 2 above base block, and runs through the dial gauge 3 of locating piece; Described reference block bottom surface is at least provided with three legs 4, and base block is provided with three exhausting holes 5 (flatness of three leg bottom surfaces is higher than the flatness of inner chamber); Described dial gauge measuring staff 6 bottom thread is connected with taper gauge head 7.
Because reference block is consistent with cavity shape, be convenient to reference block to put into workpiece lumen when measuring; And locating piece is in order to the support to dial gauge; Arrange leg in order to support reference block in reference block bottom surface further, and in base block, arrange three exhausting holes, when reference block is placed in inner chamber, the position different at inner chamber is measured, thus adopts relative measurement method, realizes the measurement to inner chamber flatness.
During measurement, first base block is positioned on flat board, taper gauge head is inserted in the through hole of base block upper surface, locating piece bottom surface is contacted with reference block upper surface; The relative position of adjustment locating piece and dial gauge, when gauge head is contacted with flat board, measuring staff is positioned at the centre position of total travel; Tight a bolt, locating piece is fastened on dial gauge; Finally dial gauge is returned to zero; Base block loaded in workpiece lumen, then inserted successively in each through hole by gauge head, make reading after locating piece bottom surface and reference block end face reliable contacts, the difference of the maxima and minima in read off is as the flatness error value of bottom surface.
Embodiment 2
On the basis of previous embodiment, in order to make dial gauge and locating piece fix, described locating piece side wall surface is provided with mounting hole 8, is provided with the bolt 9 of fixing dial gauge in this mounting hole.Number percent is arranged in mounting hole by the mode be bolted, and can prevent dial gauge from moving up and down after bolt tightening.
Embodiment 3
On the basis of embodiment 1, in order to make locating piece bottom surface and reference block end face reliable contacts, described locating piece faying face is embedded with magnet 10, and described base block faying face surface is laid with metal iron layer 11.By the generation attractive force of magnet to iron, locating piece is contacted more reliable, firm with reference block.
Embodiment 4
On the basis of embodiment 1, in order to make survey agllutination fruit more accurate, described taper gauge head bottom is provided with steel ball 12.Taper gauge head bottom employing planar shaped is easy and measuring surface is crooked, cause measuring accurate, and taper gauge head bottom adopts the design of steel ball, avoids the problems referred to above.
Embodiment 5
On the basis of embodiment 1, in order to also use above-mentioned measurement mechanism when light is darker, dial gauge inside is provided with button cell, shows to add on pushbutton switch 14, dial plate outside body to add small electric bulb 15; Described button cell, pushbutton switch, small electric bulb three serial connection.Owing to being provided with small electric bulb, the brightness that small electric bulb produces, is enough to see dial gauge surface, inner chamber flatness inspection devices also can be used when light is darker.
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.
