Description
Technical field
The utility model relates to a kind of ring groove depth detection measurer.
Background technology
In some product process of processing, often run into and show like figure one and to have end face ring groove class workpiece, this type ring groove has some common ground: groove is narrow and depth tolerances is strict.This type of picture part if consider to be to use vernier caliper or vernier depth gauge to measure its ring groove according to conventional thinking, and in operating aspect, because of vernier depth gauge card base size is bigger, should not be used for the detection of narrow groove ring groove class part; If use vernier caliper to carry out depth survey, have following drawback: (1) vernier caliper precision can not satisfy the parts measurement accuracy requirement.According to the choice criteria of measurement instrument, this part tolerance band is 0.10mm, and the uncertain permissible value of measuring appliance is 0.018mm, and the uncertain permissible value of vernier caliper is 0.02mm.(2) the measuring method operational stability is poor, is prone to produce systematic error.During the vernier caliper measurement degree of depth; As positioning reference, (1.3 * 1.7mm) length of stretching out are measured the part degree of depth, can know according to above data with secondary chi with the plane of main scale afterbody 16x3mm; The measuring basis locating surface is less; When measuring, be prone to vacillate now to the left, now to the right,, be prone to produce the data bigger than actual value so be difficult to measure vertical range.(3) be prone to produce stochastic error, measure, when the control vernier caliper is perpendicular to part, estimate the main scale and the secondary chi scale coincidence line of vernier caliper, thereby obtain measurement data, be prone to produce stochastic error with this kind measuring method.Existing that first, second, the third three ring groove that the gauger is measured
data is as shown in table 1 below:
Table 1
It is thus clear that the reading that each operator measures does not all wait, and explains that this measuring method stochastic error is bigger.
The utility model content
The utility model provides a kind of ring groove depth detection measurer, with solve the prior art operational stability poor, be prone to produce stochastic error, problem that measuring accuracy is not high.
The technical scheme of the utility model is following:
A kind of ring groove depth detection measurer comprises the magnetic force gauge stand, is fixed on the support on the magnetic force gauge stand and is installed in the dial gauge on this support, and dial gauge is made up of sounding rod and table body, and the sounding rod diameter of dial gauge is 2-1.7mm; The sounding rod front end is a sphere, and this spherical diameter is identical with the sounding rod diameter.
Above-mentioned sounding rod diameter is 1.8mm, and length is 20mm; This diameter and length dimension select to have satisfied basically the versatility of different size groove width.
Above-mentioned magnetic force gauge stand bottom can be lined with increases frock, so that satisfy higher workpiece for measurement.
The utlity model has following advantage:
1, the cubing measuring accuracy is promoted to 0.01mm by 0.02.
2, simple to operate, good stability effectively reduces measuring error.
3, can be applicable to process, the rate of reducing the number of rejects and seconds.
Description of drawings
Fig. 1 is the synoptic diagram of the sounding rod of the utility model.
Fig. 2 is the structural representation of the utility model.
The drawing reference numeral explanation:
The 1-dial gauge; The 2-sounding rod; The 21--annular knurl; The 3-measuring basis; 4-measures the bottom surface; 5-magnetic force gauge stand; 6-increases frock, 7-(on the magnetic force gauge stand) support.
Embodiment
The utility model is considered advantages such as the dial gauge measuring accuracy is high, and is easy and simple to handle, can be used for narrow type ring groove depth detection after common dial gauge sounding rod is improved.
Referring to Fig. 1, Fig. 2; The utility model ring groove depth detection measurer; Comprise magnetic force gauge stand 5, be fixed on the support 7 on the magnetic force gauge stand 5 and be installed in the dial gauge 1 on this support 7 that the sounding rod 2 of dial gauge is split type with the table body, is to be threaded through M3 or M2.5 to be integral.Sounding rod 2 diameters of dial gauge are 2-1.7mm; Sounding rod 2 front ends are sphere, and this spherical diameter is identical with the sounding rod diameter.
Select the principle of sounding rod material to be: wear-resisting, corrosion-resistant and do not receive the influence of environment temperature; Taking all factors into consideration all factors decision selection tool steel adds chrome-faced and handles and meet the demands.The sounding rod material is used tool steel T10, and modifier treatment has the fastness to rubbing that certain degree of hardness can improve sounding rod; Chrome-faced strengthens the corrosion-resistant degree of sounding rod.
Sounding rod design parameter explanation: diameter of phi 1.8mm, length 20mm (distance of sounding rod front end to annular knurl 21) is if diameter and length dimension select this group data owner in order to satisfy the versatility of different size groove width.Processing technology is considered diameter of phi 1.8 tolerances are guaranteed through cylindrical grinder, is guaranteed the smooth and roughness of termination circular arc through hand grinding at last.
Measuring staff machining process: rough turn → modifier treatment → finish turning → correct grinding cylindrical → hand grinding termination circular arc → chrome-faced.
The method of application of the utility model is as shown in Figure 2.When using the method to measure, need to prepare one on the higher platform of a flatness, one of magnetic force gauge stand if workpiece is too high, when the magnetic force gauge stand can not meet the demands, also need be prepared one and increase frock.Use: at first dial gauge is adjusted to " 0 " position at reference field, gently measuring staff is lifted then and put into measuring tank to be measured, read dial gauge numerical value again, this moment, reading was groove depth size reading, and reading accurately can satisfy the workpiece for measurement precision prescribed.
Points for attention:
1) reference field must be confirmed by correct position on surface of the work, and reference field can not be excessive to the bottom land size, in order to avoid dial gauge reading no to scale;
2) using must be fixed before the magnetic force gauge stand, must not have situation loosening or that move to take place, and prevents that gauge stand from moving to cause reading error;
3) the dial gauge measuring staff must with surface of the work Surface Vertical to be measured, inclination that must not influential measuring accuracy;
4) in the measuring process, when moving measuring staff, workpiece must not have mobile, must guarantee that measuring basis is consistent in the measuring staff moving process;
Measuring staff moves and must handle with care, stops to wrench and drags phenomenon firmly, prevents that the sounding rod vibration from causing the dial gauge reading to produce error.
Use the utility model and measure, easy and simple to handle, measured value is accurate, and precision is high; Improve production efficiency, reduced the process uncertain factor; Can extend to lathe, milling machine, detect in process, rate has realized reducing the number of rejects and seconds from the source; Original measurer (dial gauge) is not produced destructive the modification, and the part that needs is little, easy to process, and cost is low, has also improved the measurement range of measurer, can restore the original state of measurer simultaneously.
