The utility model has the following advantages and beneficial effect compared to existing technology: very conveniently can accurately detect cylinder head valve sealing line and conduit concentricity, accuracy of detection is high, structure is simple, reliability is strong, convenience is applicable.
Accompanying drawing explanation
Fig. 1 is a kind of apparatus structure schematic diagram for detecting cylinder head valve sealing line and conduit concentricity of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the present embodiment provides a kind of device for detecting cylinder head valve sealing line and conduit concentricity, comprises locating device and pick-up unit, and described locating device comprises locating sleeve 1, lower centration axis 4 and upper centration axis 6; Be used for feeling relieved and the concentricity of measuring guide, described lower centration axis 4 slip cap is loaded in tested conduit 3, realizes point cantact with the centering ball 2 be arranged in described locating sleeve 1; Be used for feeling relieved and measuring guide, lower centration axis 4 and upper centration axis 6 are by locating sleeve 1 fixed position; And pick-up unit comprises measurement pivoted housing 5 and display 10; Described display 10 is connected to by travelling carriage 12 to be measured on pivoted housing 5; Measure pivoted housing 5 outside surface and be provided with screw thread, measure pivoted housing 5 and be provided with tested valve retainer 7, measure in pivoted housing 5 and be provided with place kick 8; Described upper centration axis 6 slip cap is loaded on to measure in pivoted housing 5 and realizes point cantact with place kick 8; Upper centration axis 6 is coordinated with tested valve retainer 7 by upper end, and during use, upper centration axis 6 is inserted and measured in pivoted housing 5, and place kick 8 makes centration axis 6 very little with the tolerance clearance of tested valve retainer 7, thus reduces the measuring error of beating.
Described display 10 is connected with contact 9 by detecting block 13; Detect the single-chip microcomputer of the preferred model AD μ C843 of block 13, the described contact 9 lower end conical surface contacts with all tramlines of valve retainer 7.Contact 9 around in all tramlines contact of valve retainer 7, detect block 13 can the jerk value of Real-Time Monitoring valve retainer 7 and conduit whether accurate, information is directly shown on display 10, undesirable for jerk value, we can adjust at any time, very practical, convenient; For satisfactory measurement data, then reflect on display 10 intuitively very much, such measurement is very intuitively easy, and the data of measurement accurately and reliably.
Be described the utility model and embodiment thereof above, this description does not have restricted, and shown in accompanying drawing is also one of embodiment of the present utility model, and actual structure is not limited thereto.Generally speaking, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the structure similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
