[summary of the invention]
In order to overcome the deficiency in background technology, the utility model discloses a kind of center hole of shaft part depth measurement device, described device not only convenient operation, but also the precision that effectively can improve duplicate measurements.
For achieving the above object, the utility model adopts following technical scheme:
A kind of center hole of shaft part depth measurement device, described device comprises cubing, measurement module and sounding rod; Described cubing center is provided with through hole, and the table that the position in the corresponding aperture, through hole top of cubing is provided with for fixation measuring module presss from both sides; Described through hole bottom is set to stepped hole, and in through hole, slip is placed with sounding rod; Described sounding rod shaft is provided with gathering sill, the shaft outer casing spring of the corresponding stepped hole of sounding rod, and the termination, lower end of sounding rod is provided with spheric probe; The middle part of cubing is provided with level and is through to guider screw in gathering sill groove.
Further, described through hole top hole wall is provided with for pressing from both sides with table the screw thread that corresponding silk connects.
Further, described measurement module is digital display meter, sensor or digital display sensor.
Further, described sounding rod bottom is provided with the multidiameter corresponding with the stepped hole of through hole bottom, and the upper end of spring is corresponding with the step surface of stepped hole conflicts, and the lower end of spring is corresponding with the step surface of sounding rod multidiameter conflicts.
Further, described matched with devices is provided with an and Comparison of standards part that precision higher consistent with tested part depth of center hole.
Owing to adopting technical scheme as above, the utility model has following beneficial effect:
Center hole of shaft part depth measurement device compact conformation described in the utility model, is easy to carry, and is easy to operation, described device have employed the degree of depth being come measuring center hole by the mode of measurement module reading data, as required, described device can also fix normal data by measurement standard contrast piece, and then the data of measurement module reading and normal data are contrasted, thus draw the exact depth value in Central of the parts hole, because cubing repetitive positioning accuracy can reach 0.01mm, error when it effectively can eliminate measurement, therefore described device is not only more accurate than the measuring method of conventional apparatus, but also can directly draw data accurately by comparison Comparison of standards part, and then reach the interference effectively eliminating human factor, save the running time greatly, the corresponding object that improve production efficiency.
[accompanying drawing explanation]
Fig. 1 is schematic diagram of the present utility model.
In figure: 1, cubing; 2, through hole; 3, measurement module; 4, table folder; 5, stepped hole; 6, sounding rod; 7, gathering sill; 8, spring; 9, spheric probe; 10, guider screw.
[embodiment]
Can explain the present invention in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:
Center hole of shaft part depth measurement device by reference to the accompanying drawings described in 1, described device comprises cubing 1, measurement module 3 and sounding rod 6; Described cubing 1 center is provided with through hole 2, the position in aperture, cubing 1 corresponding through hole 2 top is provided with the table folder 4 for fixation measuring module 3, as required, digital display meter, sensor or digital display sensor can be adopted as described measurement module 3, thus reach the object utilizing measurement module 3 to measure the related data that display measurement bar 6 spheric probe 9 acquires in real time; For ease of installing, screw thread can be set out at the hole wall on through hole 2 top, thus be reached through this screw thread by corresponding with cubing 1 for table folder 4 object of fixing silk and being connected together;
Described through hole 2 bottom is set to stepped hole 5, and in through hole 2, be placed with the sounding rod 6 that can slide up and down, the shaft of this sounding rod 6 is provided with gathering sill 7, simultaneously, the middle part of cubing 1 is provided with level and is through to guider screw 10 in sounding rod 6 gathering sill 7 groove, namely can effectively limit the sense of rotation of sounding rod 6 in cubing 1 through hole 2 and the stroke of vertical direction by guider screw 10; For making sounding rod 6 can effectively conflict part and parking position accuracy, can at the shaft place outer casing spring 8 of the corresponding stepped hole 5 of sounding rod 6, thus spring 8 can be utilized to provide the acting force of conflicting and resetting for sounding rod 6; As required, the multidiameter corresponding with the stepped hole 5 of through hole 2 bottom can be set out in the bottom of sounding rod 6, and conflict corresponding with the step surface in through hole 2 lower step shape hole 5 for the upper end of spring 8 together, conflict corresponding with the step surface of sounding rod 6 multidiameter for the lower end of spring 8 together, thus ensured that sounding rod 6 can effectively utilize the acting force of spring 8 to implement the action of conflict part or parking position accuracy; For ease of the degree of depth of Parts Measurement center pit, the termination, lower end of described sounding rod 6 is provided with the spheric probe 9 can measuring induction Central of the parts hole depth.
When implementing center hole of shaft part depth measurement device described in the utility model, can directly described device be placed on part to be measured, fit corresponding with part end face for cubing 1 bottom faces, the spheric probe 9 of sounding rod 6 is contacted with the conical surface in Central of the parts hole is corresponding, and slide in cubing 1 through hole 2, thus measurement module 3 is utilized to obtain the depth value in Central of the parts hole, or, first use described device consistent with tested part depth of center hole to one, and the higher Comparison of standards part of precision is measured, make that cubing 1 is corresponding with Comparison of standards part fits, when after the spheric probe 9 of sounding rod 6 and the center pit taper-face contact of Comparison of standards part, it is made to slide in cubing 1 through hole 2, thus utilize measurement module 3 to obtain the data of Comparison of standards part center pit, now, by measurement module 3 zero setting, and remove cubing 1, sounding rod 6 is resetted under the effect of spring 8, then, re-use said method to measure part to be measured, and the data of the data obtained and Comparison of standards part are compared, finally obtain the actual grade value in accurate Central of the parts hole.
