Detailed description of the invention
Fig. 1 is the tomograph of the utility model；
Fig. 2 is the cross-sectional view of the utility model；
Fig. 3 is the A-A cross-sectional view of Fig. 2；
In the figure, it is marked as screw thread gauge head 1, top 2, detection handle 3, blind hole 4, detection slot 5.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1, Figure 2 with camshaft head end thread coaxiality cubing shown in Fig. 3, including screw thread gauge head 1 and top 2, institute
The front end for stating screw thread gauge head 1 is provided with screw thread, and the end of the screw thread gauge head 1 is provided with cylindrical detection handle 3, described top
2 front end is provided with blind hole 4, and the detection handle 3 is inserted into the blind hole 4 of top 2 front end, and the top of the blind hole 4 is provided with
The detection slot 5 communicated with blind hole 4.The camshaft head end thread coaxiality cubing of the application is broadly divided into screw thread gauge head 1 and top 2
Two parts, wherein screw thread gauge head 1, which designs, cylindrical detection handle 3, and the gauge head for dial gauge carries out taking a detection, and is pushing up
Sharp 2 front ends are provided with blind hole 4, so that cylindrical detection handle 3 is inserted into crack tip with can be convenient and are connected with top 2, the position of axle journal
Setting design has the detection slot 5 communicated with blind hole 4, and the gauge head of dial gauge is put in and is contacted with cylindrical detection handle 3.
The camshaft head end thread coaxiality cubing of the application is first packed into top 2 on deflection instrument when in use, and presses camshaft overall length
The position of adjustment deflection instrument tail centre 2, then screw thread gauge head 1 is screwed into camshaft head end threaded hole, then camshaft is filled
Enter onto deflection instrument, then it is detected with the dial gauge with gauge stand, dial indicator measuring head is protruded into top 2 axle journal when detection
On detection slot 5 in and be in contact with the cylindrical detection handle 3 of screw thread gauge head 1, then slowly rotation cam axis, percentage list index
Start to swing, one circle of rotation reads the difference of reading of dial gauge, which is the concentricity or bounce of camshaft head end screw thread.
The design of screw thread gauge head 1 matches with camshaft head end internal thread hole when specific implementation, and the thread tolerance of screw thread gauge head 1 presses pole
Limit design, production can also require the special circumstances relaxed can be by the model of super 0.005~0.02mm of limit inferior in coaxial accuracy
It encloses to design and produce.
In addition, top 2 back end outer surface of the application camshaft head end thread coaxiality cubing is the conical surface, and the conical surface
Taper is identical as top 2 taper of deflection instrument, is conducive to using identical design of the taper of the conical surface and top 2 taper of deflection instrument
Camshaft head end thread coaxiality cubing is accurate to the heart when being installed on deflection instrument, to further increase the precision of detection.
The application is also arranged fluted on detection handle 3, tightens in order to will test handle 3 with tool with camshaft.
The position that the application can also be located at below blind hole 4 in detection handle 3 is provided with mark point, so as to testing staff's grasp
Detect the angular position of rotation of handle 3.
The application is also provided with the conical surface, and the taper phase of the taper of the conical surface and camshaft center hole in top 2 front end
Together, conical surface design identical with the taper in camshaft center hole is provided with using front end, is conducive to camshaft head end threaded coaxial
It is accurate to the heart when spending cubing with cam axis connection, to further increase the precision of detection.
Using the camshaft head end thread coaxiality cubing of the application, it is only necessary to by camshaft to be detected and cam spindle nose
End thread coaxiality cubing is packed on deflection instrument together, will be convex by the screw thread gauge head 1 of camshaft head end thread coaxiality cubing
The radial dimension of variation of axle end screw thread is transmitted at cylindrical detection handle 3, makes testing staff using dial gauge in cam
Axis drives detection handle 3 to detect camshaft head end thread coaxiality or bounce while rotation, using the camshaft of the application
The detection of head end thread coaxiality cubing detects camshaft head end internal screw thread concentricity, and entire detection process is convenient, fast, detection
Precision is high.
