Embodiment Construction

[0027] The technical solution in the embodiment of this application is to solve the technical problem that the internal thread is not easy to change in the above-mentioned prior art, and the general idea is as follows:

[0028] The present invention provides an internal thread modification device, which includes a connecting piece 1, and the connecting piece 1 is provided with a boss 2, and the structure of the boss 2 matches the through hole on the base part 5 , so that the boss 2 can be sleeved in the through hole on the base part 5; and the boss 2 is provided with an internal thread. The structure of the above connector 1 , the structure of the boss 2 and the size and structure of the internal thread of the boss 2 can all be designed according to the actual needs of the base part 5 . That is, when the thread structure on the base part 5 needs to be changed, the connecting piece 1 and the boss 2 in the required internal thread changing device can be designed according to the...

Abstract

The invention discloses an internal thread changing device and method. The internal thread changing device comprises a connecting piece and a boss, and the connecting piece is provided with the boss;the structure of the boss is matched with a through hole in a matrix part, and the boss can sleeve the through hole in the matrix part; and the boss is provided with an internal thread. According to the internal thread changing device and method, the technical problem that the position and the size of internal threads in the prior art are not prone to being changed is solved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a device and method for modifying internal threads. Background technique [0002] In the field of engineering applications, internal threads are widely used. At present, there are many methods for internal thread processing, such as turning thread, milling thread, tapping thread, etc., but once the thread processing has been completed and installed on the product, if you want to change the size of the internal thread or adjust the position of the threaded hole, there are Changes are difficult, costly to change, long to change, and risky to change. In addition, when the axis of the internal thread is not perpendicular to the end face of the thread, it is difficult to change the internal thread; when the operating space required for the change of the internal thread is limited, and the tools required for the change are limited, it is also difficult to cha...
