Detailed Description
The present utility model is further described below with reference to the accompanying drawings for the convenience of understanding by those skilled in the art.
As shown in fig. 1 to 4, the bolt positioning tool for the supercharger comprises an annular main body 1, wherein a plurality of positioning columns 5 are fixedly arranged on one side of the annular main body 1, the positioning columns 5 can be matched with bolt holes on a supercharger air outlet flange, a height limiting positioning column 4 is further arranged on one side of the annular main body 1 on the same side as the positioning columns 5, and the height limiting positioning column 4 can be abutted on an end face 8 of the supercharger air outlet flange;
The outer side of the annular main body 1 of the utility model is provided with a plurality of support arms 2 which can extend to the shell 7 of the supercharger, the end parts of the plurality of support arms 2 are respectively provided with a taper locating hole, a locating sleeve 3 is arranged in each taper locating hole, the center of the bottom of each locating sleeve 3 is provided with a screw matching hole 31, the diameter of each screw matching hole 31 is larger than that of a screw 6 to be welded, the middle position of the outer side wall of each locating sleeve 3 is provided with a taper structure 32 which can be matched with the taper locating hole, and the diameter above the outer side wall of each locating sleeve 3 is larger than that below the outer side wall of each locating sleeve 3, so that the locating sleeve 3 can move upwards to be lifted from the taper locating hole.
The tool is matched with a bolt hole on a flange of an air outlet of the supercharger through a positioning column 5, then the height of the tool is limited through the matching of a height limiting positioning column 4 and the end face 8 of the flange of the air outlet of the supercharger, the position positioning of the tool is completed, after the positioning sleeve 3 is lifted to a certain height when screws to be welded are positioned, the screws 6 to be welded are inserted into screw matching holes 31, after the action is completed, the positioning sleeve 3 falls down under the self gravity, a taper structure 32 in the middle position of the outer side wall of the positioning sleeve 3 is matched with the taper positioning holes, the positioning sleeve 3 stops falling down, at the moment, the end part of the screws 6 to be welded is limited in the screw matching holes 31, the head part of the screws 6 to be welded is contacted with a shell 7 of the supercharger, the positioning of all the screws 6 to be welded is realized by workers, and finally, the tool is taken down after all the screws 6 to be welded are welded.
In order to ensure the stability during positioning, the positioning columns 5 are at least three, the circumferences of the three positioning columns 5 are uniformly distributed on the annular main body 1, and meanwhile, the height limiting positioning columns 4 are also at least three, and the height limiting positioning columns 4 and the positioning columns 5 are arranged in a staggered mode.
Because the lengths of the screws welded at different positions of the welding screws are different, in order to avoid welding errors, the utility model is arranged on the annular main body 1 close to the position of the support arm 2, or the size mark of the screw 6 to be welded is arranged on the support arm 2.
