Detailed Description
The following is a specific embodiment of the present invention, which will be further described with reference to the accompanying drawings.
As shown in fig. 3 to 5, in the auxiliary fixing tool for semi-automatic welding of the earrings, the lifting rod and the telescopic rod have the same structure; the telescopic rod is taken as an example for explanation: the telescopic rod is horizontally arranged, the telescopic rod comprises a sleeve 8 and a support rod 7 which is slidably arranged in the sleeve 8, and the sleeve 8 is in clearance fit with the support rod 7; the sleeve 8 is provided with a positioning screw 9 and a positioning nut 10 for positioning the support rod 7. After the horizontal position of the three-face fixing cover 1 is adjusted through sliding of the supporting rod 7, the supporting rod 7 and the sleeve 8 are fastened through a positioning screw 9 and a positioning nut 10.
An inclined bracket fixing plate 11 is fixedly connected between the lifting rod and the telescopic rod and used for enhancing the stability of the lifting rod and the telescopic rod. The lower end of the lifting rod is fixed with an inclined supporting leg 12, and the lower end of the lifting rod and the lower end of the supporting leg 12 are fixed on the floor through expansion screws or welded.
The telescopic link is kept away from the one end of lifter and is installed bearing 6, and the through-hole is seted up at 1 bottom plate middle part of trilateral fixed cover, and 1 through-hole suit of trilateral fixed cover is on bearing 6, and trilateral fixed cover 1 can rotate along the telescopic link axle center. Two opposite side plates of the three-side fixed cover 1 are provided with symmetrical locking screws 4 and locking nuts 3. The conical nylon block 2 is provided with a reverse threaded hole, and the conical nylon block 2 is connected and installed at the inner end of the locking screw 4 through threads; the outer end of the locking screw 4 is fixed with a locking handle 5, so that an operator can conveniently and manually tighten the screw. The conical nylon block 2 is controlled to clamp the earring by screwing in and out the locking screw 4. The conical nylon block is adopted to fix the earrings, so that the precision is high, workpieces cannot be scratched, and the earrings are suitable for earring bodies with different apertures.
The side surface of the three-surface fixed cover 1 is fixed with a reinforced tightening plate 13, and the reinforced tightening plate 13 is provided with a tightening screw 14 and a tightening nut 15.
