Embodiment Construction

[0022] see figure 1 , figure 2 with image 3 , a welding nut restorer, including a body 1, a rear cover 9 and a body cover 2. The main body of the body 1 is a cube with a bottom wall and three side walls. The rear opening is provided with the rear cover 9 . A partition 102 is provided near the front side wall in the inner cavity of the body surrounded by the bottom wall and the three side walls, so that the inner cavity of the body is divided into a front cavity 103 and a rear cavity 104 . A mouth bar 102 is arranged on the front side wall, and the mouth bar 102 is provided with a tension hole 106 communicating with the front cavity. A tension shaft 6 is slidably connected in the tension hole 106 . The front end of the pulling shaft 6 is provided with a nut gripping end 601 , and the nut gripping end 601 is provided with threads. A shaft shoulder 602 is provided on the rear end of the tension shaft 6 , and a driving hole 603 is provided on the end surface of the shaft s...

Abstract

The invention discloses a weld nut repairing device which comprises a body, wherein a mouth rod is arranged at the front end of the body; a tension hole is formed in the mouth rod; a tension shaft is connected in the tension hole in a sliding manner; the body is provided with a body inner cavity; the tension hole passes through the front wall of the body inner cavity and is communicated with the body inner cavity; a front shaft seat and a rear shaft seat are arranged in the body inner cavity; a screw rod pair comprising a screw rod and a drive nut is in pivot joint between the two shaft seats; one end of the screw rod extends out of the rear shaft seat to form an external drive end; and the drive nut is connected with the rear end of the tension shaft. Through the structure, the nut repairing device realizes nut repair through a mechanical mode, and is convenient to carry and suitable for field operation. Moreover, since the external drive end is a standard drive interface, the nut repairing device can be driven by a general spanner in field operation and by a pneumatic spanner in a repair shop or factory.

Description

technical field [0001] The invention relates to a vehicle repair tool, in particular to a vehicle weld nut restorer. Background technique [0002] Now the repair welding of the falling off nut is done by CO2 shielded welding. The use of CO2 shielded welding requires the welding machine to move to the repair welding position, which also has higher technical requirements for the personnel who perform the repair welding. The labor intensity is high, the operation is cumbersome, the process requirements are high, and the cost is high. The long preparation and operation time required for repair welding seriously affects the production cycle of the final assembly, and it is easy to cause burns and damage to other interior accessories. And even if the above-mentioned problems do not occur in welding, it is easy to cause rust and corrosion of the welded part. [0003] In the prior art, a "full-automatic pneumatic rivet gun" is usually used to repair the fallen nuts. For this type...
