Abstract
The utility model discloses a preheat consent lower hole depth measuring device, be equipped with the sleeve of first external screw thread, be longer than the measuring section of preheating the consent lower hole depth and the plug that the cooperation section constitutes, be equipped with the step gauge of recess and reference surface including length including the lower extreme, the upper end of cooperation section is located the sleeve, and the lower extreme is equipped with the boss, the bottom surface of recess is equipped with measures the face and measures the face down. The utility model has the advantages of being simple in structure and convenient in operation, can effectively reduce intensity of labour, can carry out the site survey frequently, immediately, in succession.
Description
Technical field
The utility model belongs to measurement mechanism, is specifically related to a kind of measurement mechanism that is used to detect hole depth under the preheating consent.
Background technology
Engine cylinder cover preheating consent is made up of last hole that is truncated cone-shaped and cylindrical hole down; The internal diameter in last hole from top to bottom diminishes gradually and the centre is provided with internal thread; The internal diameter in following hole then diminishes suddenly; Wherein, the position that the last hole of a part of preheating consent is connected with following hole is that the plane is provided with, and another part is the chamfering setting.Three-coordinates measuring machine can be used for the following hole depth of the preheating consent that measurement plane is provided with, but the following hole depth of the preheating consent that is provided with of energy measurement chamfering not.Even it is adopt three-coordinates measuring machine to measure, not enough below still existing: as 1,, to make Measuring Time long, can not in time provide measurement result to instruct produced on-site owing to need constant temperature and need set up coordinate system; 2, the three-dimensional chamber is far away apart from erecting yard, operating personnel's loading and unloading censorship, and labour intensity is big; 3, can not satisfy the needs of high frequency time, continuous coverage.
Summary of the invention
The purpose of the utility model be for overcome above-mentioned deficiency provide a kind of simple in structure, easy to use, can high frequency time, carry out hole depth measurement mechanism under the preheating consent of in-site measurement immediately, continuously.
For realizing above-mentioned purpose; The hole depth measurement mechanism comprises that the lower end is provided with the first externally threaded sleeve, is longer than the measuring section of hole depth under the preheating consent and is cooperated the plug that section constitutes, the step rule that are provided with groove and reference field by length under the preheating consent of the utility model; The said upper end of section that cooperates is positioned at sleeve; The lower end is provided with boss, and the bottom surface of said groove is provided with measurement face and following measurement face.
Further, comprise also and the said handle that cooperates the section upper end to be connected that the upper end of said cooperation section is provided with second external thread, said handle is provided with the internal thread that matches with second external thread.
Further, said cooperation section and sleeve wringing fit.
Further, said step rule also are provided with handle.
The advantage of the utility model is:
1) easy to use, can directly carry out on-line measurement or the measurement of line limit at erecting yard, can avoid engine cylinder cover is moved on the flat board between monitor station or measurement, reduced labour intensity.。
2) obtain measurement result fast, the stand-by period is short.
3) simple in structure, manufacturing cost and use cost is all lower.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model user mode synoptic diagram.
Fig. 3 is the A portion enlarged diagram of Fig. 2.
Among the figure: 1-sleeve (11-first external thread), 2-plug (21-measuring section, 22-cooperate section, 221-boss, 222-second external thread), 3-step are advised (measurement face, 32-reference field, 33-handle under 31-groove, the last measurement face of 311-, the 312-), 4-handle (41-internal thread), 5-engine cylinder cover (under the 51-preheating consent on hole, the 52-preheating consent hole).
Embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
The utility model comprises that the lower end is provided with the sleeve 1 of first external thread 11, is longer than the measuring section 21 of hole 51 degree of depth under the preheating consent and is cooperated the plug 2 that section 22 constitutes, step rule 3, the handle 4 that is provided with groove 31 and reference field 32 by length; The said lower end and the upper end of section 22 of cooperating is respectively equipped with the boss 221 and second external thread 222; Its upper end be positioned at sleeve 1 and with sleeve 1 wringing fit; Said handle 4 is provided with the internal thread 41 that matches with second external thread 222; Said step rule 3 also are provided with handle 33, and the bottom surface of said groove 31 is provided with measurement face 311 and following measurement face 312.
The said distance H that goes up between measurement face 311 and following measurement face 312 and the reference field 32
1And H
2Can obtain by following formula respectively: H
1=R (ctg α+(b-a
1)) sin α, H
2=R (ctg α+(b-a
2)) sin α, wherein, R is the radius in hole 51 under the preheating consent, and α is the angle of preheating consent axle center and surface level, and b is the length of measuring section 21, a
1Be the higher limit of hole 51 degree of depth under the preheating consent, a
2Lower limit for hole 51 degree of depth under the preheating consent.In the present embodiment, the radius R in hole 51 is 3mm under the preheating consent, and the angle of preheating consent axle center and surface level is 70.5 °, and the length b of measuring section 21 is 17.98mm, and the depth design value in hole 51 is (16.92 ± 0.2) mm, i.e. higher limit a under the preheating consent
1Be 17.12mm, lower limit a
2Be 16.72mm, the distance H between last measurement face 311 and the reference field 32
1For: 3 (ctg70.5+ (17.98-17.12)) sin70.5=1.81mm, the distance H between following measurement face 312 and the reference field 32
2For: 3 (ctg70.5+ (17.98-16.72)) sin70.5=2.19mm.
During measurement, tighten, be about to sleeve 1 and be connected with the preheating consent earlier with in the hole 51 under hole 52 and the preheating consent on the preheating consent that inserts engine cylinder cover 5 after plug 2 and sleeve 1 and handle 4 assemblings successively, and with first external thread 11 and the internal thread of preheating consent; Pin measuring section 21 that handle 4 makes plug 2 again and put in fully under the preheating consent in the hole 51, at this moment, hole 52 wringing fits on boss 221 and the preheating consent; Fitted in the lower surface in hole 51 under the reference field 32 of step rule 3 and the preheating consent at last, if the least significant end of measuring section 21 between last measurement face 311 and following measurement face 312, then survey the degree of depth in hole under the preheating consent be qualified.
