Embodiment Construction

[0009] The present invention will be further explained below in conjunction with the accompanying drawings.

[0010] A worm wheel central hole detection marking device is characterized in that it includes a detection plate with a central hole, a keyway corresponding to the position of the keyway in the central hole of the worm wheel to be tested, and a key mated with the keyway. There are also side holes corresponding to the positions of the side holes of the worm wheel, and there are two key grooves in the center hole, which are relatively opened on the wall of the center hole, and are relatively arranged on both sides of the two key grooves.

[0011] The center of the keyway in the side hole and the center hole forms a certain angle a on the circumference; there are two keyways in the center hole, which are relatively set on the wall of the center hole.

[0012] The above content is only a preferred embodiment of the present invention, and is not intended to limit the implem...

Abstract

The invention discloses a worm gear center hole detection marking device which is characterized by comprising a detection plate with a center hole, a key groove corresponding to the position of the key groove of the center hole of a to-be-tested worm gear, a key matched with the key slot is additionally arranged, a side hole corresponding to the position of the side hole of the worm gear is further formed in the detection board, and two key grooves in the center hole are formed and oppositely arranged on the wall of the central hole and oppositely arranged on the two sides of the two key grooves. By the adoption of the scheme, the device is compact in structure, and convenient to use, and is tidy and attractive, and the detection efficiency of the included angle between the two holes of the worm gear can be improved. The accuracy of the detection is ensured, the processing is fast, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of inspection tools, in particular to a scribing device for detecting and marking a center hole of a worm wheel. Background technique [0002] At present, the conventional method detects that the worm gear is clamped on the indexing head, the keyway of the worm wheel is fitted with a key, the reference plane is found on the key, the angle is shaken with the indexing head, and the angle is visually measured with a height ruler, which cannot guarantee the accuracy of the angle. Contents of the invention [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide a scribing device for detecting the central hole of a worm wheel. [0004] A worm wheel central hole detection marking device is characterized in that it includes a detection plate with a central hole, a keyway corresponding to the position of the keyway in the central hole of the worm wheel to be tested, a...
