Embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of embodiment.It will be appreciated that, mentioned in following embodiment of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side " be all taking the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technical scheme of the present invention.
Cylinder head oblique surface machining depth check tool of the present invention is by being positioned cylinder head on this cubing base plate, and detection through hole is offered in the position on corresponding cylinder head to be detected inclined-plane on support plate, make the center line that detects through hole perpendicular to cylinder head to be detected inclined-plane, if need to carry out position probing perpendicular to the machining hole on inclined-plane in addition on inclined-plane, the center line that detects through hole also needs to overlap with the machining hole center line on cylinder head to be detected inclined-plane; Then detecting assembling and positioning survey cover on through hole, and it is parallel with cylinder head to be detected inclined-plane to make location survey the outer face of overlapping, the last supporting scanning rule through calibration, whether the outer face working depth that detects cylinder head to be detected inclined-plane to the distance on cylinder head to be detected inclined-plane of surveying cover by detection and location is consistent with theoretical size, and whether the working depth that can detect cylinder head to be detected inclined-plane is qualified.
As depicted in figs. 1 and 2, the concrete structure of this cylinder head oblique surface machining depth check tool comprises: base plate 1, support plate 2, scanning rule 3 and measuring staff 4, wherein, base plate 1 is for supporting and location cylinder head to be detected, support plate 2 is vertically set on a side of base plate 1, scanning rule 3 and measuring staff 4 are located on support plate 2, for detection of the working depth on cylinder head inclined-plane.
Base plate 1 is rectangular plate shape, and four jiaos of bottom surfaces are respectively arranged with vertical leg 11, and the left and right sides is separately installed with bridge type handle 12.The end face of base plate 1 is also laid with rhombus reference column 13, back-up block 14 and the circular reference column 15 with cylinder head bottom supporting to be detected location.Wherein, back-up block 14 is three, and triangularity is arranged, with more stable support cylinder head to be detected.Rhombus reference column 13 and circular reference column 15 form the detent mechanism of " plane and two pits ", to cylinder head to be detected bottom surface accurate positioning, quick, make to after the accuracy of detection of the cylinder head oblique surface machining degree of depth higher.
Can be found out by vertical view, support plate 2 is two, is vertically set on respectively the end face upside of base plate 1; Rhombus reference column 13, back-up block 14 and circular reference column 15 are distributed in the cylinder head to be detected bottom surface locating area of the end face downside of base plate 1.Spaced apart several detection through holes 21 that is provided with of upper lateral of support plate 2, the corresponding cylinder head incline position of this detection through hole 21 is offered, and detect the center line of through hole 21 perpendicular to cylinder head inclined-plane, if need detection position perpendicular to the machining hole on inclined-plane in addition on inclined-plane, the center line that detects through hole 21 also needs to overlap with the center line of machining hole to be detected.Each outside of detecting through hole 21 is equipped with location and surveys cover 22, and the accommodation hole that cover 22 is surveyed in location overlaps with the center line that detects through hole 21, and outer face is parallel with cylinder head to be detected inclined-plane.
As shown in Figure 3, scanning rule 3 comprises: dial gauge 31, cubing body 32 and gauge head 33.Wherein, cubing body 32 is tubulose, and lateral wall middle part has radial protrusion, and the lower surface of this radial protrusion is the cooperating face of surveying cover 22 outer faces with location; Top is fixed with end cap 35 by bolt 34.The measuring staff of dial gauge 31 wears in end cap 35 by resilient sleeve 36, and resilient sleeve 36 is passed through lock-screw 37 from end cap 35 side surface lockings.Gauge head 33 is bolt shape, the screw rod of bolt shape gauge head 33 is stretched into by the lower end of cubing body 32, prop up the measuring staff lower end gauge head of dial gauge 31, between screw tip and end cap 35, be also provided with Compress Spring 38, make bolt shape gauge head 33 self-returns of the measuring staff lower end gauge head that pushes against dial gauge 31, detect to complete again; The head bottom surface of bolt shape gauge head 33 is the detection faces contacting with cylinder head to be detected inclined-plane; While detecting cylinder head inclined-plane, scanning rule 3 is located in location by cubing body 32 and surveys on cover 22, prop up cylinder head to be detected inclined-plane by the head bottom surface of bolt shape gauge head 33, the measuring staff lower end gauge head that the screw rod of bolt shape gauge head 33 props up dial gauge 31 detects reading.Scanning rule 3 also comprises: stop screw 39, screwed in by the side of cubing body 32, and the spacing head of the head of stop screw 38 stretches into the sidewall stopper slot of gauge head 33 screw rods, and gauge head 33 and cubing body 32 are relatively moved while detection, unlikelyly from cubing body 32, comes off.
Before detection, need to calibrate scanning rule 3 by calibrating device 5.Calibrating device 5 is tubular structure, and top is survey cover outer face, location to the distance of cylinder end inside surface and arrives the distance of Standard Gases cylinder cap inclined-plane (bevel depth processing is qualified).When scanning rule 3 is calibrated, cubing body 32 inserts in calibrating device 5, the lower surface backstop of cubing body 32 radial protrusions is in calibrating device 5 tops, an inside surface at the bottom of the head bottom surface of bolt shape gauge head 33 props up tin, now, the reading of dial gauge 31 is survey cover outer face, location and arrives the distance of Standard Gases cylinder cap inclined-plane (bevel depth processing is qualified).Equally, in the time that the cubing body 32 insertion location survey covers of scanning rule 3 detect, the lower surface backstop of cubing body 32 radial protrusions is surveyed cover outer face in location, the head bottom surface of bolt shape gauge head 33 props up cylinder head to be detected inclined-plane 6, if the reading of dial gauge 31 is consistent with the reading of calibration, illustrate that the working depth on cylinder head to be detected inclined-plane 6 is qualified.
As shown in Figure 4, measuring staff 4 is the large multidiameter small in ends in middle part, and upper end is the handle 41 with burr, and middle part is the positioning section 42 of surveying the adaptive plug-in mounting of accommodation hole of cover 22 with location, and lower end is the detection head 43 detecting with the adaptive plug-in mounting in oblique surface machining to be detected hole.Overlap with cylinder head oblique surface machining centerline hole to be detected because detect the center line of through hole, if oblique surface machining to be detected hole Working position is qualified, the positioning section 42 of measuring staff 4 inserts location and surveys while overlapping, and detection head 43 should just in time insert oblique surface machining to be detected hole.
This cylinder head oblique surface machining depth check tool is simple and reasonable, easy and simple to handle, whether the outer face working depth that detects cylinder head to be detected inclined-plane to the distance on cylinder head to be detected inclined-plane of surveying cover by the scanning rule detection and location of cylinder head being determined and pass through calibration is qualified, detection efficiency and quality are all high, and testing cost is low.
Disclosed is above only several specific embodiment of the present invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
