Description
Technical field
The present invention relates to a kind of location and measurement mechanism, particularly relate to a kind of turbine and evenly locate and measurement mechanism, belong to assembling and measure frock.
background technology:cooling turbine unit is the refrigeration annex of the air-conditioning system of many plant equipment, forms primarily of the turbine disk and turbine cover; During assembling, the tolerance clearance between the turbine disk and turbine cover must control the job requirement that could meet cooling turbine unit within 0.45 ~ 0.7mm.But due to the turbine disk and turbine cover complex structure, tolerance clearance is between the two hidden in turbine cover inside, general measurer cannot be adopted directly to measure; Therefore a kind of can measurement above-mentioned gap and the specific purpose tool of assembling and positioning is needed.
summary of the invention:in order to overcome the defect existed in prior art, the present invention aims to provide a kind of turbine radial clearance uniformity location and measurement mechanism, and the fit-up gap between the turbine disk and turbine cover meets designing requirement to utilize this device to guarantee.
To achieve these goals, the present invention is by the following technical solutions: it comprises on locating piece in epsilon-type structure, this locating piece and is diametrically evenly equipped with three kidney grooves, be fixed on the screw rod on this locating piece, be enclosed within this screw rod is evenly equipped with three chutes rotating disk, be located at this rotating disk compresses by screw rod nut, be each passed through each kidney groove and insert measuring piece in fish hook formation in corresponding chute, be located in each chute and the sliding pin be fixedly connected with this measuring piece, the cover plate that is fixed on disc surfaces; Each chute is helically line distribution centered by the axis of screw rod.
Spring is provided with between locating piece and rotating disk; Each measuring piece is provided with gathering sill, is fixed with the guide finger through described gathering sill in each kidney groove; The external cylindrical surface of locating piece is evenly equipped with three clamping screws; Rotating disk or cover plate are fixed with handle.
Compared with the prior art, the present invention is owing to have employed technique scheme, utilize the locating piece of epsilon-type structure to insert in turbine cover to position, by stretching into the radial and axial motion of three measuring pieces in turbine cover, thus the tolerance clearance that ancistroid,ancistrous measuring piece front end is inserted between the turbine disk and turbine cover can be measured, then can converse the tolerance clearance between the turbine disk and turbine cover by the distance measured between screw rod end face and cover plate.Structure of the present invention is simple, easy to use, measure and positioning precision high.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the A direction view in Fig. 1;
Fig. 4 is working state structure schematic diagram of the present invention.
In figure: clamping screw 1 kidney groove 2 sliding pin 3 handle 4 screw rod 5 nut 6 cover plate 7 rotating disk 8 locating piece 9 spring 10 measuring piece 11 gathering sill 12 guide finger 13 chute 14 turbine cover 15 turbine disk 16
embodiment:below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As shown in Figures 1 to 3: the locating piece 9 in epsilon-type structure is fixed with screw rod 5, the end face of this locating piece has three kidney grooves 2 diametrically uniform centered by this screw rod, and the rotating disk 8 be enclosed within screw rod 5 is compressed by the nut 6 be located on this screw rod; Rotating disk 8 end face is evenly equipped with three chutes 14, and each chute 14 is helically line distribution centered by the axis of screw rod 5.Be provided with sliding pin 3 in each chute 14, three measuring pieces 11 in fish hook formation are fixedly connected with the sliding pin 3 in corresponding chute 14 through kidney groove 2.In order to prevent measuring piece 11 from moving around along axis side, the surface of rotating disk 8 is fixed with cover plate 7.
In order to easy to use, be provided with between locating piece 9 and rotating disk 8 and be enclosed within spring 10 on screw rod 5.In order to avoid measuring piece 11 deflects, guarantees the accurate inserted into gap in ancistroid,ancistrous working position, its front end, each measuring piece 11 is provided with gathering sill 12, in each kidney groove 2, is fixed with the guide finger 13 through described gathering sill.In order to ensure that location is reliable, the external cylindrical surface of locating piece 9 is evenly equipped with three clamping screws 1.For the ease of stirring rotating disk 8, this rotating disk or cover plate 7 are fixed with handle 4.
As shown in Figure 4: during work, rotate counterclockwise rotating disk 8, make each measuring piece 11 draw in minimum position along locating piece 9 radial direction under the effect of chute 14; Then apparatus of the present invention are inserted in the outlet of turbine cover 15 by locating piece 9, ensure to fit at the bottom of the end face of this outlet and the ring groove of locating piece 9, tighten clamping screw 1.Stir rotating disk clockwise, each measuring piece 11 is moved to outside radial direction and between the turbine disk 16 with turbine cover 15, coordinates gap place, unclamp nut 6 rear spring 10 just can by rotating disk 8 drive the ancistroid,ancistrous working position of measuring piece 11 insert described in cooperation gap, then the distance adjusted between screw rod 5 end face and cover plate 7 can determine the tolerance clearance between the turbine disk 16 and turbine cover 15 indirectly.After this tolerance clearance is determined, by adjustment, also fixed turbine dish 16 and the relative position of turbine cover 15 can guarantee the homogeneity coordinating interval between the two; Finally, suitable fastening nut 6, measuring piece 11 working position is exited coordinate gap, then stir rotating disk 8 counterclockwise, unclamp clamping screw 1 and this device can be taken out from the outlet of turbine cover 15.
