In addition, the projection welding machine is not easy to replace the hajig due to the type and wear of the door strike to be obtained because the hajig which needs to be replaced by the center difference of the U-shaft is integrated with the lower tip. .

In addition, as the first inspection of the u-shaft is performed by the naked eye, the defective rate of the finished product is high and even when the defect occurs, even if the whole number can be recovered by using the rod number, even the finished product is inspected by the manual inspection gauge. Not only can not be inspected also can not be done properly because the defects will continue to have a number of problems, such as the possibility of a fatal injury to the occupants due to the failure of the door strike.

The present invention improves productivity by unmanned automation of the process from the single part supply of the base plate and the u-shaft to the inspection of the finished product in order to solve the above-mentioned problems. It is easy to replace the tip due to the wear and the type of door strip to be obtained, and the u-shaft removes the defect by measuring the height and deviation by digital gauge in the supplying process, and also the dimensions and verticality of the finished product Its purpose is to provide an automobile door strike manufacturing apparatus that minimizes the incidence of defects and removes them in the event of failures, as a result of overall defect inspection, which leads to height defect inspection during upsetting due to breakage of the upper tip during welding. have.

In order to achieve the above object, the present invention has a stopper for controlling the supply of the u-shaft between the parts feeder for supplying the u-shaft and the rail guide among the parts feeder for supplying the u-shaft and the base plate. Based on the height set in the master gauge, two digital gauges independently measure the left and right heights of the u-shaft and install a u-shaft inspection unit that detects defects.The part feeder that supplies the base plate has a type punch. One rod number rudder unit is installed, and on the other side, a base plate transfer unit with finger parts connected to the base operating up and down along the LM guide is installed to transfer the base plate on which the rod number is swept forward to step by step along the rail guide. It is assembled with the u-shaft which is transferred to the Several guide plates with different intervals are installed along the LM guide to move the product transfer unit operated by the front and rear cylinders and the left and right cylinders to transfer the individual parts, assemblies and finished products to the finished product inspection unit step by step.
