Embodiment 1

[0015] Such as figure 1 As shown, a semicircular keyway symmetry checker includes a plugboard 1 inserted into the semicircular keyway on the camshaft, and the upper surface and the lower surface of the plugboard 1 are attached to the groove wall of the semicircular keyway 2, so A support frame 3 is fixedly installed on the upper or lower surface of the insert plate 1, and a dial indicator 4 is detachably installed on the support frame 3, and the measuring head 5 of the dial indicator 4 abuts on the camshaft 6 , the inserting plate is inserted into the semicircular keyway so that the upper surface of the inserting plate faces upwards, the measuring head of the dial indicator is pressed against the camshaft, and the reading of the dial indicator is read, and then the upper surface of the inserting plate faces downwards, and the dial indicator is pressed against the camshaft. The measuring head of the sub-meter touches the camshaft, reads the reading of the dial indicator, and ca...

Embodiment 2

[0017] Embodiment 2: The structure of Embodiment 2 is basically the same as that of Embodiment 1, the difference is: as Figure 2 to Figure 4 As shown, the inserting board includes an upper plate 9 and a lower plate 10, a guide rod 11 is provided between the upper board 9 and the lower board 10, and a first hinge seat 12 is provided at the first end of the guide rod 11, The first hinged seat 12 is hinged with a first connecting rod 13 and a second connecting rod 14 which are arranged symmetrically to each other and have equal lengths. The second end of the guide rod 11 is provided with a second hinged seat 15. The second A third connecting rod 16 parallel to the first connecting rod and a fourth connecting rod 17 parallel to the second connecting rod are hinged on the hinge seat, and the third connecting rod 16 is hinged on the upper plate 9, so The fourth connecting rod 17 is hinged on the lower plate 10, the first connecting rod 13, the second connecting rod 14, the upper pl...

Abstract

The invention discloses a symmetry gauge of a semi-circular keyway. The gauge comprises a plugging plate plugged into a semi-circular keyway of a camshaft. The upper surface and the lower surface of the plugging plate are in contact with the wall of the semi-circular keyway. A support frame is fixedly installed on the upper surface or the lower surface of the plugging plate; a dial gauge is detachably mounted on the support frame; and the measuring head of the dial gauge is abutted against the camshaft. The plugging plate is inserted into the semi-circular keyway and thus the upper surface ofthe plugging plate is arranged upwardly. The measuring head of the dial gauge is abutted against the camshaft and the number on the dial gauge is read; the upper surface of the plugging plate is arranged downwardly and the measuring head of the dial gauge is abutted against the camshaft, and the number on the dial gauge is read; and the difference between the numbers of the two measurement resultsis calculated, so that the symmetry of the semi-circular keyway can be detected. The operation becomes convenient; and the measurement is accurate and reliable.

Description

technical field [0001] The invention relates to a semicircular keyway symmetry inspection tool. Background technique [0002] In the prior art, when testing the symmetry of the semicircular keyway on the camshaft, only general-purpose checking tools can be used. During the testing, there are defects of cumbersome operation and low measurement accuracy, which affects the efficiency of batch testing. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a semicircular keyway symmetry inspection tool that can efficiently detect the position of the semicircular keyway, has strong versatility, and has various functions. [0004] The technical solution of the present invention is: a semicircular keyway symmetry inspection tool, including a plugboard inserted into the semicircular keyway on the camshaft, the upper surface and the lower surface of the plugboard are attached to the groove wall of the semicircular keyway, ...
