Abstract
Title: An Auxiliary Tooling for Drilling Holes on Annular Wall of Motor End Cover Abstract The invention discloses auxiliary tooling for drilling holes on the annular wall of a motor end cover. The auxiliary tooling comprises a base on which an upright post is fixed, the middle part of the front of the upright post is provided with a mandrel which is perpendicular to the upright post, the upright post is provided with a positioning pin above and below the mandrel respectively, the center connecting lines of the mandrel and the positioning pins are on the same straight line, and the top of the upright post is provided with a drill plate on which a fixing drill bush is fixed. With the above technical scheme, the invention can rapidly and accurately position a motor end cover through the mandrel and the positioning pins which are respectively arranged above and blow the mandrel. .. . . . . . . .. . . . . ..N . . . .. .. . . .. . . . . . .. . . . . .. . . . . lA FIG.1 FIG.2
Description
Description An Auxiliary Tooling for Drilling Holes on Annular Wall of Motor End Cover Technical Field The invention relates to a drill jig for a motor end cover, in particular to auxiliary tooling for drilling holes on the annular wall of a motor end cover. Background of the Invention As shown in FIG.1 and FIG.2, a motor end cover has a side wall and a bottom end, holes are drilled on the bottom end, and the side wall is provided with radial through holes. The method commonly used for forming radial through holes is to drill on a hole-punching mold by a punch. However, because one end of the motor end cover is of a planar surface, and the other end is of a non-planar surface, it is difficult to be positioned. At present, although special auxiliary tooling for drill jigs is available, the positioning is not fast and accurate enough and thus affects the machining efficiency of the motor end cover. Summary of the Invention The object of the invention is to provide auxiliary tooling for drilling holes on the annular wall of a motor end cover, which can realize fast and accurate positioning. In order to realize the object, the invention employs the following technical scheme: auxiliary tooling for drilling holes on the annular wall of a motor end cover is characterized in that a base is included, an upright post is fixed on the base, the middle part of the front of the upright post is provided with a mandrel which is perpendicular to the upright post, the upright post is provided with a positioning pin above and below the mandrel respectively, the center connecting lines of the mandrel and the positioning pins are on the same straight line, and the top of the upright post is provided with a drill plate on which a fixing drill bush is fixed. Preferably, the upright post is fixed on the base by a screw. The drill plate is fixed on the upright post by a screw. The manufacture and assembly are convenient. Preferably, the mandrel and the positioning pins extend out of the rear of the upright post and form a positioning plane behind the upright post, and the drill plate is provided with the fixing drill bush above the mandrel corresponding to the rear of the upright post. Operations of positioning a motor end cover to proceed machining can be simultaneously carried out in front of and behind the upright post, and thus, the machining efficiency is improved. With the above technical scheme, the invention can rapidly and accurately position a motor end cover through the mandrel and the positioning pins which are respectively arranged above and blow the mandrel. Brief Description of the Drawings The invention will be further described by combining the following drawings and embodiment: 1 HG. 1 is a schematic diagram of a motor end cover; HG2 is an A-A sectional view in FIG. 1; and HG3 is a structural diagram of the invention. Detailed Description of the Invention HG3 shows an embodiment of the invention of auxiliary tooling for drilling holes on the annular wall of a motor end cover. The auxiliary tooling comprises a base 7 on which an upright post 4 is fixed, the middle part of the front of the upright post is provided with a mandrel 6 which is perpendicular to the upright post, the upright post is provided with a positioning pin 5 above and below the mandrel respectively, the center connecting lines of the mandrel and the positioning pins are on the same straight line, and the top of the upright post is provided with a drill plate 2 on which a fixing drill bush 3 is fixed. The upright post is fixed on the base by a screw 1. The drill plate is fixed on the upright post by a screw 1. The mandrel 6 and the positioning pins 5 extend out of the rear of the upright post 4 and form a positioning plane behind the upright post, and the drill plate is provided with the fixing drill bush above the mandrel corresponding to the rear of the upright post. 2
