Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a high strength rivet nut's tapping device, includes briquetting 10, carousel 14, briquetting 10 includes boss 11, first arc surface 12, the first conical surface 13, the left side of briquetting 10 is provided with boss 11, the right side of briquetting 10 still is equipped with first arc surface 12, be equipped with first conical surface 13 between boss 11 and the first arc surface 12.
The rotary table 14 is provided with a plurality of feed openings 17, second arc surfaces 16 are arranged in the feed openings 17, and second conical surfaces 15 are arranged on two sides of each second arc surface 16.
The roundness of the second arc surface 16 is consistent with that of the first arc surface 12, and the taper of the second cone surface 15 is consistent with that of the first cone surface 13, so that the matching degree of the pressing block 10 and the rotating disc 14 can be better ensured, and a product can be better surrounded.
The boss 11 is matched with the edge of the rotary table 14, and the first arc surface 12 and the second arc surface 16 are both matched with the outer diameter of the nut; the idle running of the equipment can be prevented, the pressing block 10 is prevented from pressing the head to cause the wear of the screw tap, and the clearance between the boss 11 and the rotary table 14 is controlled to control the clearance between the first arc surface 12 and the product and the clearance between the second arc surface 16 and the product.
Through holes 18 are formed in the pressing block 10 and the rotary table 14; the weight of the searching device reduces the manufacturing cost.
The working principle is as follows: the nut to be processed is placed into the feed opening 17, the pressing block 10 presses the nut, and the first arc surface 12 and the second arc surface 16 are matched to surround the nut. The boss 11 is matched with the edge of the rotary table 14, the gap between the arc surface and the nut is controlled by controlling the gap between the boss 11 and the rotary table 14, the nut is circular, the screw tap has torque when tapping threads, if the pressing block 10 is not clamped tightly, the nut is easy to rotate, and the pressing block 10 is too tightly clamped, the nut is easy to press and deform. The clearance between the boss 11 of the pressing block 10 and the turntable 14 is important.
For ease of description, the orientations referred to above are now specified as follows: the up, down, left, right, and front-back directions described above coincide with the up, down, left, right, and front-back directions of the projection relation of fig. 1 itself.
