Differential connection structure of laser guiding arm

Abstract

The invention relates to a differential connection structure of a laser guiding arm. The differential connection structure structurally comprises a reducing connector and a light guiding extension pipe; one end of the reducing connector forms a connection female taper tap end, one end of the light guiding extension pipe forms a connection male taper tap end, and the connection male taper tap end of the light guiding extension pipe can stretch into the connection female taper tap end and can be correspondently matched with the connection female taper tap; the outer wall of the reducing connector corresponding to the connection male taper tap end is provided with a third tightening thread, the outer wall of the light guiding extension pipe is provided with a fourth tightening thread, and the fourth tightening thread is adjacent to the connection male taper tap end; and a differential nut is sleeved on the light guiding extension pipe, the light guiding extension pipe is connected with the differential nut in a tightening way through the fourth tightening thread, the connection female taper tap end of the reducing connector is sleeved on the connection male taper tap end and stretches into the differential nut, the reducing connector is connected with the differential nut in tightening way through the third tightening thread, and the axes of the reducing connector, the differential nut and the light guiding extension pipe stay on the same straight line. The differential connection structure has a simple and compact structure, and the stability and reliability of the laser guiding arm can be improved.

Description

technical field [0001] The invention relates to a connection structure, in particular to a differential connection structure of a laser light guide arm, and belongs to the technical field of laser light guide arms. Background technique [0002] At present, in the laser light guide arm, the connection method between the solid-line refraction head and the light guide tube can be a threaded connection with a lock nut or a flange connection, but these connection methods cannot guarantee the coaxial accuracy after the connection and provide sufficient connection strength. In large-scale mechanical processing, in order to ensure the assembly accuracy of processing tools (such as machining centers) and transmit large rotational moments, "taper shank" connections are used, and some nuts are added outside the taper shank connections to strengthen The pull-off strength of the connection. However, none of the above-mentioned upper processing methods can meet the working requirements ...
