Description
Technical field
The utility model belongs to the mechanical measurement technique field, is specifically related to a kind of superdeep holes depth measurement device.
Background technology
TU5JP4 cylinder cap mail gallery holes length is 390.7 ± 0.3mm, and diameter is φ 8(+0.43/-0.15) mm, belong to superdeep holes.Usually the ratio of hole depth and diameter reaches 5 times, just belongs to deep hole, and the ratio of this main oil gallery degree of depth and diameter surpasses 48 times, is typical superdeep holes.In prior art, the measuring method of hole depth is split type measuring staff to be inserted in oil hole measure.
But there is following defective in prior art:
1, in use, the operator repeatedly forgets split type measuring staff in mail gallery holes, caused forge a knife, measuring staff is scrapped, part is scrapped phenomenon;
2, manufacturing cycle of reordering after measuring staff is scrapped is long, and because measuring staff is elongate rod, axial dimension is difficult to processing, guarantees the dimensional tolerence difficulty, work easily occurs useless in manufacture process;
3, can directly affect the quality monitoring of manufactured parts.
Summary of the invention
The purpose of this utility model is exactly for defects, provide a kind of measurement accurately, efficient is high, the quality of part played the superdeep holes depth measurement device of effective monitoring.
The technical solution adopted in the utility model is: a kind of superdeep holes depth measurement device, comprise measuring staff and the logical stops that can be enclosed within on measuring staff, measuring staff is comprised of with the bar core that is connected with the bar handle the bar handle, and logical stops comprises go side and not-go-end, and the go side thickness of logical stops is greater than not-go-end thickness.
Further, be equipped with groove in the middle part of the go side of described logical stops and not-go-end, logical stops coordinates with measuring staff by groove.
Further, described bar handle surface is provided with netted screw thread, and because of measuring staff size overlength, measuring staff needs certain effect power when extracting out from hole in piece part, thereby the netted thread surface of design can increase the anti-stopping bar handle landing from hand of the friction force of holding the bar handle.
By auxiliary logical stops, judge whether hole depth is qualified during the measured hole degree of depth.Actual measurement length with measuring staff in manufacture process is prepared logical stops, has reduced the manufacturing accuracy requirement of measuring staff length, and the difficulty of measuring staff manufacturing tolerance is transferred on logical stops, and the size of logical stops is than the easy assurance of measuring staff.
During manufacturing,
Go side gauge L1 satisfies: the mm of bar core size measured value-L1=390.4(-0.0525/-0.0775); Not-go-end gauge L2 satisfies: the mm of bar core size measured value-L2=391(+0.0425/+0.0175).
The utility model design monoblock type measuring staff, alternative measuring staff adds the split-type structural of gauge stand, avoided split type measuring staff to be retained in causing in hole in piece part forge a knife, measuring staff is scrapped, part is scrapped phenomenon.Design assistant leads to stops, and the manufacturing tolerance of Extra-Long Measuring Bars is transferred on logical stops, has reduced manufacturing requirement and the difficulty of Extra-Long Measuring Bars, judges by logical stops whether part is qualified in use procedure, and it is high that logical stops replaces meter reading efficient.Only need after wearing and tearing to change or the logical stops of reconditioning, save cost, the manufacturing cycle is short.This cubing fundamentally solved superdeep holes depth check tool manufacture difficulty large, forge a knife when using, measuring staff is scrapped, part is scrapped and the inefficient problem of parts measurement.
The utility model superdeep holes depth measurement device successfully uses on cylinder cap, measures accurately, efficient is high, and the quality of part is played effective monitoring, uses good.This measurement mechanism is equally applicable to the depth survey of other superdeep holes, simultaneously, can also extend to the little hole depth of similar tolerance and detect, substitutes to touch to advise and measure.

Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments, be convenient to be well understood to the present invention, but they do not consist of restriction to the present invention.
As shown in Fig. 1-4, the utility model comprises measuring staff 1 and the logical stops 4 that can be enclosed within on measuring staff 1, and measuring staff 1 is comprised of with the bar core 3 that is connected with bar handle 2 bar handle 2, and logical stops 4 comprises go side 6 and not-go-end 5, and go side 6 thickness of logical stops 4 are greater than not-go-end 5 thickness.The go side 6 of logical stops 4 and not-go-end 5 middle parts are equipped with groove 7, and during use, logical stops 4 is connected with measuring staff 1 by the groove 7 on go side 6 or not-go-end 5.Bar handle 2 surfaces are provided with netted screw thread 8, and because of measuring staff size overlength, measuring staff need to act on certain hour when extracting out from hole in piece part, thereby the netted thread surface of design can increase the anti-stopping bar handle landing from hand of the friction force of holding the bar handle.
The degree of depth of hole in piece part has definite range of size, and whether the degree of depth that detect the hole meets the demands, and needs specific pick-up unit, and available technology adopting split-type structural measuring staff detects hole depth, and the processing request of this measuring staff is higher and be difficult to guarantee dimensional tolerence.The utility model Design assistant leads to stops 4, prepare logical stops 4 with the length of the bar core 2 of measuring staff 1 in manufacture process, the manufacturing tolerance of Extra-Long Measuring Bars is transferred on logical stops, the size of logical stops is than the easy assurance of measuring staff, the manufacturing accuracy that has reduced Extra-Long Measuring Bars requires and difficulty, by auxiliary logical stops, judge whether hole depth is qualified during the measured hole degree of depth.During manufacturing, the gauge L1 of go side satisfies: bar core size measured value-L1=390.4(-0.0525/-0.0775); The gauge L2 of not-go-end satisfies: bar core size measured value-L2=391(+0.0425/+0.0175).
The method that the utility model detects hole depth is: as shown in Figure 5, at first measuring staff 1 is put in tested part hole 9, more logical fast 4 the go side 6 of stopping is inserted between the end face of measuring staffs 1 and part 10, go side 6 can not be passed through; The not-go-end 5 of logical stops 4 is inserted between measuring staff 1 and part 10 end faces, not-go-end 5 can pass through again, and part is qualified.If carry out same operation, logical, the not-go-end of logical stops all can not pass through, and the processing of the hole depth of part is dark, is that the not-go-end of measurement mechanism is overproof, and hole in piece part processing is dark defective, has not reprocessed surplus; If carry out same operation, logical, the not-go-end of logical stops all can pass through, and the processing of the hole of part is shallow, is that the go side of measurement mechanism is defective, and the hole depth of part should be reprocessed, and can do over again.
