Abstract
The utility model discloses a tool for measuring the hole distance of a generator main shaft connecting hole. The tool comprises a taper core shaft (1) which is internally provided with a screw rod (2) which passes through the taper core shaft (1). Two ends of the screw rod (2) are respectively provided with a pressing plate (3) and a nut (4). An elastic taper sleeve sleeves the outer wall of the taper core shaft (1). The tool has the advantages of simple structure and convenient use, the hole distance can be quickly measured by using the tool, the relative position size between holes is ensured, and the working efficiency is raised.
Description
Technical field
The utility model relates to a kind of hole distance measuring device, particularly a kind of for generator shaft connecting hole hole distance measuring device.
Background technology
At present, on generator shaft, for the connecting hole being connected with other parts, that the method that adopts the part that is connected with other simultaneously to process is manufactured in normal circumstances, but, owing to being subject to accessory size, the restriction of weight and equipment, the connecting hole of the connecting hole on generator shaft and the part that is connected cannot be processed simultaneously, can only adopt the method for processing respectively to manufacture, now, position dimension for the connecting hole of correlated parts just must carry out strict control, in this control procedure, just must measure the relative position between connecting hole and connecting hole.
Utility model content
The purpose of this utility model is just to provide a kind of survey instrument for generator shaft connecting hole pitch-row that can fast and easy, carry out accurately pitch-row measurement.
The purpose of this utility model is to realize by such technical scheme, a kind of survey instrument for generator shaft connecting hole pitch-row, described instrument comprises taper core axle, the screw rod that runs through tapering mandrel is set in tapering mandrel, be respectively arranged with pressing plate and nut at the two ends of described screw rod, on the outer wall of tapering mandrel, be arranged with elastic conical drogue.
Further describe, described tapering mandrel comprises tapered section and measuring section, and described elastic conical drogue is arranged on tapered section, and the two ends of described pressing plate are corresponding with the small end of described elastic conical drogue.
Owing to having adopted technique scheme, the utlity model has advantage simple in structure, easy to use, adopt it to measure pitch-row fast, guarantee the relative position size between each hole, improve work efficiency.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any improvement on the present embodiment essence spirit or substitute, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of survey instrument of generator shaft connecting hole pitch-row, it is characterized in that: described instrument comprises taper core axle 1, run through the screw rod 2 of tapering mandrel 1 in the interior setting of tapering mandrel 1, be respectively arranged with pressing plate 3 and nut 4 at the two ends of described screw rod 2, on the outer wall of tapering mandrel 1, be arranged with elastic conical drogue 5.
Wherein, described tapering mandrel 1 comprises tapered section 6 and measuring section 7, and described elastic conical drogue 5 is arranged on tapered section 6, and the two ends of described pressing plate 3 are corresponding with the small end of described elastic conical drogue 5.
The utility model is to use like this: first elastic conical drogue 5 is packed in the connecting hole of the main shaft 7 processing, tapering mandrel 1 is penetrated in elastic conical drogue 5, then screw rod 2, pressing plate 3 and nut 4 are installed, fastening nut 4 after installing, under the tapering effect of tapering mandrel 1, elastic conical drogue 5 external diameters increase, and make whole survey instrument tensioner in connecting hole.When measurement, take two survey instruments as one group, detect the distance between survey instrument and the survey instrument in connecting hole by milscale.
