The detection device is used for detecting the inner step hole formed on the ceramic plunger with small diameter, and is inserted into the inner step hole through the extended measuring end on the detection shaft, and the numerical value of the depth of the inner step hole is obtained by the plug piece of unchanged specification added at the gap, the original measuring mode of using a vernier caliper is substituted, and generation of errors in measurement is avoided. The detection device is simple in design, fast in detection and suitable for rapid detection on batches of ceramic plungers.
Description
Technical field:
The utility model relates to a kind of pick-up unit, relates in particular to the depth detection apparatus of stepped hole in a kind of elongated ceramic plunger processing.
Background technology:
Generally be applied to the porcelain bushing on agricultural pump, the high pressure cleaning pump, the diameter of its porcelain bushing itself is less, in porcelain bushing, also offer high-precision interior stepped hole, whether stepped hole closely is directly connected to the impermeability of pump in being somebody's turn to do when socket, do not allow to such an extent that produce any error when supporting in socket, no side affects the use of pump.
During original interior stepped hole on the processing ceramic plunger, all be directly to measure by vernier caliper, in measurement, the depth offset of stepped hole is 0～0.15mm in being somebody's turn to do, owing to there is artificial many factors, is easy to cause the measurement of interior stepped hole inaccurate, and the material of this ceramic plunger is pottery, vernier caliper puts in to be measured, and is easy to scratch interior stepped hole, causes the generation of defective products.
Summary of the invention:
The technical matters that the utility model solves provide stepped hole in a kind of elongated ceramic plunger depth detection, and can be fit to fast detecting in enormous quantities, guarantee that the interior stepped hole of ceramic plunger of precision processes pick-up unit.
The technical scheme in the invention for solving the technical problem is: stepped hole processing pick-up unit in a kind of ceramic plunger, comprise and detect axle, patch, described detection axle is stepped, detects the front end of axle for stretching out measuring junction, and the rear end of detecting axle is the lever position; This patch can be socketed in and stretch out on the measuring junction; The described front end face width that stretches out measuring junction is D1, and the extension elongation of stretching out measuring junction is D2, and wherein, D1 equals the aperture d1 in hole, ceramic plunger upper inner platform rank, and D2 is greater than the depth d 2 of stepped hole in the ceramic plunger.
In order to prevent the meeting landing in testing process of this pick-up unit, offer screw thread at this lever position, be convenient to staff and hold on the lever position.
Further, the quantity of described patch is at least one.
Simultaneously, for can directly embody on the quantity of patch detect in the degree of depth of stepped hole, described patch have thickness be 0.1mm several, 0.2mm several, 0.05mm several.
The beneficial effects of the utility model are: this pick-up unit is for the detection of the interior stepped hole of offering on the ceramic plunger of tiny diameter, be inserted in the interior stepped hole by the measuring junction that stretches out that detects on the axle, and the patch by the fixedly specification of adding at gap location, to obtain the depth value of interior stepped hole, perhaps, the one-tenth-value thickness 1/10 of patch need the stepped hole of processing to exist in the tolerance value, as long as also can directly be measured the machining precision of stepped hole less than this error amount; Replace former useful vernier caliper measurement, produce error when avoiding measuring, this mechanism simplicity of design detects fast, can be fit to the fast detecting of ceramic plunger in enormous quantities.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the synoptic diagram of the utility model pick-up unit in concrete the use.
Among the figure: 1, detect axle 11, screw thread 12, stretch out measuring junction 13, lever position 2, patch 3, ceramic plunger.
Embodiment:
Stepped hole processing pick-up unit in a kind of ceramic plunger comprises and detects axle 1, patch 2 as shown in Figure 1, and described detection axle 1 is stepped, detect the front end of axle 1 for stretching out measuring junction 12, the rear end of detecting axle 1 is lever position 13, and simultaneously, this detection axle 1 is the shaft that pottery is made for material; This patch 2 can be socketed in and stretch out on the measuring junction 12; The described front end face width that stretches out measuring junction 12 is D1, the extension elongation of stretching out measuring junction 12 is D2, and wherein, D1 equals the aperture d1 in hole, ceramic plunger upper inner platform rank, D2 is greater than the depth d 2 of stepped hole in the ceramic plunger, and it is the thickness sum of N patch that D2 deducts the numerical value that d2 obtains.
In order to prevent the meeting landing in testing process of this pick-up unit, offer screw thread 11 at this lever position 13, be convenient to staff and hold on the lever position.
Further, the quantity of described patch 2 is at least one.
Simultaneously, for can directly embody on the quantity of patch 2 detect in the degree of depth of stepped hole, described patch 2 have thickness be 0.1mm several, 0.2mm several, 0.05mm several.
This pick-up unit is for the detection of the interior stepped hole of offering on the ceramic plunger 3 of tiny diameter, be inserted in the interior stepped hole by the measuring junction 12 that stretches out that detects on the axle, and the quantity of the patch 2 by the fixedly specification of adding at gap location, to obtain the depth value of interior stepped hole, replace former useful vernier caliper measurement, produce error, this mechanism simplicity of design when avoiding measuring, detect fast, can be fit to the fast detecting of stepped hole in ceramic plunger 3 processing in enormous quantities.
The method of this device Quick Measurement also is applicable to: need the stepped hole of processing to have the tolerance value, as long as the one-tenth-value thickness 1/10 of patch also can directly be measured the machining precision of stepped hole less than this error amount.
Example: the interior step dimension of converted products is ￠ 15*10, the tolerance of height 10 is+0.15, that is to say that the step segment length is 10.15 to 10, the lower part of the pick-up unit of doing is of a size of ￠ 15*10.15, during detection, puts into the step of product, as long as the slit is arranged, and be no more than 0.15 just in margin tolerance, therefore as long as take 0.15 patch, and plug does not enter the slit and gets final product.
It is emphasized that, it more than is better implementation column of the present utility model, be not that this pick-up unit is done any type of restriction in appearance, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
