Abstract

The invention provides a double-layer punching tool for a control valve deck. The double-layer punching tool comprises a bottom layer circular ring, a top layer circular ring, a connecting armature, a bottom layer drill jig, a locating groove, a top layer drill jig, a fixing screw rod, a weight and a locating pile. The bottom layer circular ring is an iron circular ring, the ring surface of the bottom layer circular ring is provided with the bottom layer drill jig, and the locating groove is formed in the ring surface. The top layer circular ring is an iron circular ring and is connected with the bottom layer circular ring through the connecting armature, and the top layer drill jig is arranged on the ring surface of the top layer circular ring. The locating pile is arranged on the bottom layer circular ring. The control valve deck and the tool are connected through the fixing screw rod and pressed and fixed through the weight. The double-layer punching tool is simple in structure, accurate in location and high in practicality, and improves the production efficiency to a great extent.

Description

technical field [0001] The invention relates to a tool, in particular to a double-layer punching tool for controlling a valve cover. Background technique [0002] At present, some small casting processing factories use scribe positioning to punch holes one by one when punching some workpieces. This not only has large shape and position tolerances, but also has cumbersome procedures and high labor intensity, making it difficult to achieve mass production. Contents of the invention [0003] In view of the problem of large tolerances in the positioning of workpiece punching and marking lines, the technical problem to be solved by the present invention is to provide a double-layer punching tool for controlling the valve cover. The utility model has the advantages of simple structure, precise positioning and strong practicability, and greatly improves production efficiency. [0004] In order to achieve the above object, the technical scheme that the present invention take...
