The invention provides a poking device of a screw tap thread mill, belongs to the technical field of machinery, and solves the problems of lower coaxiality of a screw tap and incapability of reaching the precision requirements in grinding by a traditional screw tap thread mill. The poking device of the screw tap thread mill comprises a box body; a rotating body capable of rotating is inserted in the box body; the middle part of the rotating body is fixedly connected with a tip; the outer end of the rotating body is coated with a cylindrical fixed sleeve; the outer end of the fixed sleeve is fixedly connected with an adjusting sleeve; a floating sleeve is arranged in the adjusting sleeve; the outer end of the floating sleeve is fixedly connected with a float poking plate; a positioning hole is formed in the middle part of the float poking plate for penetrating through the tail part of the screw tap; the outer side wall of the floating sleeve is vertically and fixedly connected with a transmission rod; the transmission rod is peripherally and fixedly connected with the adjusting sleeve; a pressure spring is arranged between the floating sleeve and the adjusting sleeve; and two ends of the pressure spring are respectively butted against the floating sleeve and the adjusting sleeve. The poking device of the screw tap thread mill has the advantages of capability of swinging the ejected screw tap and higher grinding precision.
Description
Technical field [0001] The invention belongs to the technical field of machinery, and relates to a tap thread mill, in particular to a toggle device of a tap thread mill. Background technique [0002] Thread is the most commonly used method for connecting mechanical parts. Tap is the most commonly used tool for processing internal threads. It has a simple structure and is easy to use. For small-sized internal threads, taps are almost the only processing tool. The production process of taps is: blanking flat head chamfering center hole → rough grinding outer circle → grinding square tail → grinding groove → fine grinding outer circle → grinding thread → shoveling, thread grinding is the final process of tap thread processing, cutting The precision of the thread is an important guarantee for the thread precision of the processed product. When the thread of a tap is being ground, two centers are needed to locate the center hole of the tap. The rotation of the tap is driven by the h...
