Thread transfer printing device

Abstract

The invention provides a thread transfer printing device.The thread transfer printing device comprises a transfer printing base, adjustable nut limiting pieces, adjustable mandrel limiting pieces, a pressing device, a dowel and a rotating device.The transfer printing base is in a cake shape, kidney-shaped slots are milled, and the vertical section of the transfer printing base is a reverse isosceles trapezoid.Inner threads are arranged.The transfer printing base is further provided with reinforcing ribs.The adjustable nut limiting pieces and the adjustable mandrel limiting pieces are each in an arc shape, and the bottoms of the adjustable nut limiting pieces and the bottoms of the adjustable mandrel limiting pieces are connected with limiting blocks.The adjustable mandrel limiting pieces are provided with concave-convex threads.The limiting blocks are installed in the kidney-shaped slots in a sliding mode, and limiting threads matched with the inner threads are arranged on the surfaces of the limiting blocks.The pressing device is in a right angle shape and is fixed outside the transfer printing base.The dowel is installed at the upper end of the pressing device, and the rotating device is connected with the dowel.The problem that the occupied area is too large due to the fact that a large number of machining tools are needed in the prior art is solved, and the working environment is improved; the machining efficiency of the inner threads is improved; the advantages of being easy to manufacture, low in cost and suitable for machining other nut-like workpieces are achieved.

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
