Description
Technical field
The utility model relates to distance-measuring device, is specifically related to a kind of measurement mechanism that detects hole in piece part centre to end.
Background technology
A lot of parts have two orthogonal end faces; Be designed with circular hole on one of them end face, the relative position of circular hole and other end, promptly the center, hole is most important for assembling, the use of parts to the distance of this end face; Big slightly or slightly little assembling, the result of use that all can directly have influence on parts of distance; Even make the part of processing become waste product, therefore, whether detection hole in piece part centre to end adheres to specification is very important routine work in the part processing process.Existing detection method commonly used is to adopt three coordinate measuring engine measurement.This method is measured more accurate, but because the three-dimensional chamber is far away from the scene of part processing usually, the workload of operating personnel's loading and unloading, censorship is bigger; Can't satisfy especially for the occasion that needs high frequency time, continuous coverage.
Summary of the invention
The purpose of the utility model is exactly that a kind of measurement mechanism that detects hole in piece part centre to end will be provided, and can measure the distance of hole in piece part center to end continuously, apace, can effectively reduce labour intensity.
For realizing above-mentioned purpose, the measurement mechanism of the detection hole in piece part centre to end that the utility model designed is made up of location comparison mechanism and error measure mechanism; Said location comparison mechanism comprise the sleeve of back-end closure, excellent body be positioned at sleeve and with friction tight plug of sleeve and spring; The front portion of said sleeve is cylindrical; The front end of said plug is the revolution bodily form of end diameter less than excellent body diameter; Also be provided with positioning runner on the said plug, said sleeve is provided with the jackscrew that matches with positioning runner, and said spring is between the rear end of the rear inside of sleeve and plug; Said error measure mechanism comprises slide block and is vertically fixed on the dial gauge on the slide block.
Further, the said revolution bodily form is truncated cone-shaped or taper shape.
Further, the rear end of said sleeve also is provided with end cap, and said end cap is connected with back-end sealing.
The advantage of the utility model is:
1) easy to use, can directly carry out on-line measurement or line limit and measure, measure thereby can avoid that part is transported to the three-dimensional chamber, reduced operator's labour intensity.
2) measurement result is quick, and the stand-by period is short.
3) simple in structure, manufacturing cost and use cost is lower.
Description of drawings
Fig. 1 is the utility model structure and user mode synoptic diagram.
Among the figure: 1-sleeve (11-rear end, anterior, the 13-end cap of 12-), 2-plug (21-rod body, 22-front end, 23-positioning runner, 24-rear end), 3-spring, 4-jackscrew, 5-slide block (51-right side, 52-mounting hole, 53-boss, 54-lower plane), 6-dial gauge (61-lining, 62-butterfly screw, 63-gauge head), 7-part to be measured (71-hole, 72-upper surface, 73-right side).
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail.
A kind of measurement mechanism that detects hole in piece part centre to end shown in Figure 1 is made up of location comparison mechanism and error measure mechanism; Sleeve 1, the excellent body 21 that said location comparison mechanism comprises be positioned at sleeve 1 and with sleeve 1 friction tight plug 2 and spring 3; The internal diameter of said sleeve 1 is greater than the diameter in the hole 71 of part 7 to be measured; Sleeve 1 rear end 11 be provided with end cap 13; Said end cap 13 and rear end 11 are connected through thread seal; The front portion 12 of said sleeve 1 is cylindrical, and the design load of this columniform radius and part 7 to be measured 71 centers, distance of 72 to the upper surface from the hole is identical, and the front end 22 of said plug 2 is the truncated cone-shaped of end diameter less than excellent body 21 diameters; The end diameter of this truncated cone-shaped is less than the diameter in hole 71; The excellent body 21 rear portion outer walls of said plug 2 also are provided with positioning runner 23, and said sleeve 1 is provided with the jackscrew 5 that matches with positioning runner 23, and said spring 3 is between the rear end 24 of end cap 13 inboards and plug 2; Said error measure mechanism comprises slide block 5 and is vertically fixed on the dial gauge 6 on the slide block 5, and in the present embodiment, the right side 51 of slide block 5 is provided with the boss 53 of band mounting hole 52, and dial gauge 6 is fixed on mounting hole 52 through lining 61 and butterfly screw 62.
During detection; The first step: the front end 22 that at first plug 2 is truncated cone-shaped inserts in the hole 71 of part 7 to be measured; Because the end diameter of this truncated cone-shaped is less than the diameter in hole 71, excellent body 21 diameters are greater than the diameter in hole 71, therefore; The process of plug 2 patchholes 71 is promptly for being carried out the transition to the process of interference fit by clearance fit.Then, the end cap 13 of hand sleeve 1, along with the contraction of spring 3, sleeve 1 travels forward, until its cylindrical anterior 12 be close to part 7 to be measured right side 73.At this moment, the central axis of the central axis of the center in hole 71 and plug 2 and sleeve 1 is positioned at same axis.Second step: earlier slide block 5 is placed on the calibration plane; Make the certain amount of gauge head 63 compressions of dial gauge 6; And the pointer of dial gauge 6 made zero, again the lower plane 54 of slide block 5 is fitted with the upper surface 72 of part 7 to be measured, the gauge head 63 of dial gauge 6 is contacted with sleeve 1 cylindrical anterior 12; The vertical direction of the axle in edge and hole 71 is moving slider 5 slowly; The pointer of dial gauge 6 begins to do clockwise deflection, then does counterclockwise deflection, the sensing numerical value the when pointer of dial gauge 6 becomes counterclockwise deflection by clockwise deflection; The deviation of the center that is hole 71 distance of 72 to the upper surface, and 71 centers, the hole radius value that 72 distance is sleeve 1 anterior 12 to the upper surface deducts the reading value of dial gauge 6.Therefore, if this deviation at 71 centers, hole in the design tolerance scope of the distance of upper surface 72, then 72 distance is qualified to the upper surface at 71 centers, hole of this part 7 to be measured, otherwise defective.
