In this embodiment, as shown in fig. 1, engine cylinder head portable concentricity inspection stick, including first inspection section 2, changeover portion 10 and second inspection section 9, first inspection section 2 and second inspection section 9 pass through changeover portion 10 and connect, the diameter of first inspection section 2 is greater than the diameter of changeover portion 10, can prevent that changeover portion 10 from causing wearing and tearing to the processing hole pore wall, the one end that is close to changeover portion 10 on the second inspection section 9 is the toper platform, insert the back, toper platform cooperates with the bell mouth, after toper platform can cooperate with the bell mouth, then show that first inspection section 2 can insert to wait to detect downtheholely, thereby then show that the concentricity of waiting to detect the hole is qualified. The other end of the second inspection section 9 is provided with a limiting plate 3, the diameter of the limiting plate 3 is larger than that of the second inspection section 9, and the limiting plate 3 is connected with the holding end. Furthermore, the insertion end of the first inspection section 2 forms an insertion head 1 through a chamfer, so that the design is convenient for the inspection rod to be inserted into a processing hole to be detected, and the abrasion to the hole wall when the insertion head 1 is inserted into the processing hole can be avoided. Because the inspection stick is a standard component, the cost of processing is higher, during the detection, insert the inspection stick with strength, limiting plate 3 and workpiece surface contact back, the inspection stick then can't continue to insert before, at this moment, first inspection section 2 just also can not insert forward, and first inspection section 2 then enters into completely waiting to detect downthehole, transition section 10 can not take place to interfere with the pore wall of machined hole if the concentricity of machined hole is qualified so, the wearing and tearing have been avoided, transition section 10 takes place to interfere with the pore wall if the concentricity is unqualified so, the staff takes out the inspection stick and takes out the record result. At first place the work piece that waits to detect on examining test table, the handheld end of holding of staff, at first insert first inspection section 2 and wait to detect downthehole, insert changeover portion 10 and second inspection section 9 afterwards, the concentricity in hole about first inspection section 2 and second inspection section 9 detect respectively, it is qualified that the concentricity detects then to explain when all can inserting completely downthehole, the staff takes out the inspection stick, can in time carry out the concentricity detection like this, and check-out time is short, the manufacturing efficiency of engine is provided.
In this embodiment, the holding end includes connecting rod 4 and holding rod, and the holding rod quadrature is installed in the one end of connecting rod 4, and the other end and the limiting plate 3 of connecting rod 4 are connected. Further, the holding rod includes screw thread section 5 and smooth section 6, and screw thread section 5 and smooth section 6 are installed in the both sides of connecting rod 4, and further again, smooth section 6's one end still is provided with top cap 7, installs hood 8 on the top cap 7, and hood 8's surface is provided with a plurality of recesses. The screw thread section 5 can provide two kinds of detection mode for the staff, and one of them is that the screw hole on the staff is qualified to the machined part with screw thread section 5 on the inspection stick detects, and is downthehole with screw thread section 5 rotation insertion screw thread, if do not take place to interfere then to explain the screw hole qualified, if take place to interfere then unqualifiedly. And secondly, the operator holds the holding rod to detect the concentricity of the workpiece. Wherein the top cap 8 surface on smooth section 6 is provided with the recess, is in order to increase the friction, and the inspection stick is difficult for the landing in the testing process.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
