Description

Technical Field

[0001] The utility model relates to the technical field of worm production, in particular to a detection device for detecting the length of worm production. Background Art

[0002] A worm is a gear with one or more spiral teeth that meshes with a worm wheel to form a staggered axis gear pair. Its indexing surface can be a cylindrical surface, a conical surface or a torus surface. There are four types of worms: Archimedean worms, involute worms, normal straight flank worms, and conical envelope cylindrical worms. The length of the worm needs to be measured in worm production.

[0003] According to a Chinese patent with the announcement number "CN214702188U", a detection device for detecting the length of worm gear production is disclosed, which includes a supporting device, a positioning device, a fixing device, a moving device, a detection device and a display device. The supporting device includes a table top, a bracket and a supporting frame. The lower surfaces of the two brackets are connected to the upper surface of the table top, and the lower surfaces of the two supporting frames are connected to the upper surface of the table top. The positioning device includes a mounting plate and bolts. The upper surfaces of the two mounting plates and the upper surface of the table top are provided with threaded holes, and the two bolts are respectively connected to the threaded holes. The fixing device includes a fixing box, a first gear, a moving rod and a rotating handle. The lower surface of the fixing box is connected to the upper surface of the table top, the first gear is meshed with the moving rod, a first through hole is provided on one side surface of the fixing box, the moving rod is connected to the first through hole, a circular hole is provided on one side surface of the fixing box, and one end of the rotating handle passes through the circular hole and is connected to the outer surface of the moving rod.

[0004] Although the device can measure the length of the fixed screw through the detection head, only one screw can be fixed at a time, so only the length of one screw can be measured. Therefore, when the length of multiple screws needs to be measured, a lot of time needs to be spent on fixing the screws, which leads to low measurement efficiency. Therefore, a detection device for detecting the length of worm production is proposed to solve the above-mentioned problems. Utility Model Content
