Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
as shown in fig. 1-3, a spiral streak detector comprises a base 1, wherein 4 adjustable feet 14 are installed at the lower end of the base 1, so that the level of a working table can be conveniently adjusted. The spindle box part is fixed on the base 1 through bolts and comprises a spindle box body 16, a spindle box cover 8 is mounted at the upper end of the spindle box body 16, a spindle 9 is mounted in the spindle box body 16, a front end bearing 15 is mounted at the front end of the spindle 9, the outer ring of the front end bearing 15 is fastened with the spindle box body 16 through a spindle front cover 11, a rear end bearing 17 is mounted at the rear end of the spindle 9, and the outer ring of the rear end bearing 17 is fastened with the spindle box body 16 through a spindle rear cover 7. The right end face of the nut 6 is connected with the left end face of the inner ring of the rear end bearing 17 into a whole through a top sleeve 18, and the nut 6 is provided with a bolt 5 for locking the nut 6 after the position of the nut 6 is adjusted in place. The front end of the main shaft 9 is fixedly connected with a front hole type three-jaw chuck 13 through screws for clamping a workpiece to be detected, and a heavy hammer 12 is hung on the excircle of the spiral thread to be detected through cotton threads. The front end of the main shaft box cover 8 and the upper part of the front hole type three-jaw chuck 13 are provided with a three-jaw chuck protective cover 10 made of organic glass materials. The orthogonal speed regulating motor 2 is arranged on the base 1 through a support 3, a motor shaft of the orthogonal speed regulating motor 2 is connected with the rear end of the main shaft 9 through a coupler 19, and a protective cover 4 is arranged above the coupler 19 to ensure the use safety of an operator.
