Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended for purposes of illustration only and is not intended to limit the scope of the present disclosure. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The utility model provides a pair of general utmost point ear fixed-position welding device, include: welding mechanism 5 and the setting is at the positioning mechanism of welding mechanism 5 below, and positioning mechanism places on workstation 1.
