Panel and Nut Supporting Device for Nut Welding Apparatus for Preventing Eccentric

摘要

The subject innovation relates to a nut and panel support device of the nut-welding which prevents the ball of the fastening nut of the ball screw panel that eccentricity is welded so as to improve the reliability of the product. The process of matching a screw hole of the fastening ball nut of the first electrode and the panel and a second electrode positioned opposite to the lower portion of the first electrode, and presses the nut welded to the panel positioned between a first electrode and a second electrode in the nut for welding machine, the top of the second electrode is fixed to a fixed portion having a receiving recess in the top, and is coupled to the upper portion, the support panel so as to cover the receiving grooves of the government. Engagement of said nut guide pins are each panel received a lower part in the receiving groove of the government is, constitutes a part the upper panel guide pin which is exposed to the panel guide pin and coaxial with the panel supporting part is exposed to the upper side through the panel guide pin and a slope portion which is inserted to the ball of the ball screw nut to maintain a close contact state without mutual clearance. Panel guide pin and guide pin nut by supplying air at a predetermined pressure into the receiving groove of the fixing portion from the air pump is always supported by the upper constant.
