Thread transfer device

Abstract

A thread transfer printing device comprises a transfer printing base, adjustable nut limiting sheets, adjustable core rod limiting sheets, a pressing device, a pin and a rotating device. The transfer printing base is in a cake shape, kidney-shaped grooves are formed in the transfer printing base in a milling mode, the vertical section of each kidney-shaped groove is in an inverted isosceles trapezoid shape, and each kidney-shaped groove is provided with an internal thread. The transfer printing base is further provided with reinforcing ribs. The adjustable nut limiting sheets and the adjustable core rod limiting sheets are respectively in an arc shape, and the bottoms of the adjustable nut limiting sheets and the bottoms of the adjustable core rod limiting sheets are respectively connected with a limiting block. The adjustable core rod limiting sheets are provided with concave and convex threads, each limiting block is arranged in the corresponding kidney-shaped groove in a sliding mode, and the surface of each limiting block is provided with a limiting thread matched with the corresponding internal thread. The pressing device is in a right-angle shape and is fixed outside the transfer printing base. The pin is arranged at the upper end of the pressing device. The rotating device is connected with the pin. The thread transfer printing device solves the problems that because a lot of machining tools are needed originally, the occupied area is large, and therefore the working environment is improved. Machining efficiency of internal threads is improved. Besides, the thread transfer printing device has the advantages of being easy to manufacture, low in cost and suitable for machining other kinds of nut workpieces.

Description

technical field [0001] The invention belongs to the field of thread processing equipment, and in particular relates to a thread transfer device which can transfer threads on the inner surface of different nuts according to the sizes of the nuts. Background technique [0002] With the development of current technology, the shape and precision of parts are required to be higher and higher in production. In various existing equipment and products, nuts can be seen everywhere. In order to make these equipment or products more sophisticated, the nuts need to be finished. [0003] In the existing method for machining internal threads of nuts, it is usually necessary to select a corresponding tool according to the size of the inner diameter of the nut, insert into the inner diameter of the nut for rotation, and process the inner thread. Due to the different sizes of the nuts, more internal thread processing tools are required, but only one processing tool is required for each inte...

AI Technical Summary

Problems solved by technology

Due to the different sizes of the nuts, more internal thread processing tools are required, but only one processing tool is required for each internal thread processing, which easily leads to the placement of processing tools everywhere, which not only increases the floor space, but also increases the work efficiency. The environment is complex, and it is easy to cause the loss of processing tools
