Tool setting shaft adjusting device for numerical control spark erosion drilling machine

Abstract

The invention relates to the technical field of numerical control machine tools, and discloses a tool setting shaft adjusting device for a numerical control spark erosion drilling machine. The tool setting shaft adjusting device comprises a base, a workbench, a tool shaft, a fixing column, a power assembly, a deburring assembly and an electrode wire, the top end of the base and the bottom end of the workbench are fixedly installed, the top end of the workbench is movably connected with the bottom end of the tool shaft, and the inner wall of the fixing column is movably connected with the outer wall of the power assembly. According to the tool setting shaft adjusting device for the numerical control spark erosion drilling machine, a user controls the tool shaft to move so as to drive a guide rod to move, so that a telescopic rod and a reset spring which are extruded in the perforating stage return to the original positions, and when an electric sliding block makes contact with the outer wall of a clamping block, the electric sliding block moves to enter the inner wall of a connecting ring, the electric sliding block moves to drive a rotating disc to rotate, and rotary grinding is performed by means of extrusion matching of a ball ejecting rod and a machined part, so that the effect that in the punching process of the machined part, the outer surface of the machined part is deburred after machining is finished is achieved.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a tool setting shaft adjustment device for a numerical control electric spark punching machine. Background technique [0002] Today's EDM piercing machines generally use EDM technology, which is usually aimed at workpieces with high machining accuracy and small aperture. Now, for the drilling, milling and boring process of traditional lathes, EDM piercing is not affected by the hardness of the workpiece itself. Limitation, use the vertical reciprocating movement of the knife shaft and the electrode wire to drill holes. In view of the high temperature generated by the continuous discharge between the electrode and the metal, the effect of corroding and perforating through the high temperature surrounding release is usually required during the operation. Protective measures to avoid direct contact of the human body with electricity. [0003] At present, the...

Problems solved by technology

[0003] At present, there are many types of EDM piercers on the market, which are subdivided according to the different size requirements of the piercing. Since most piercing is realized by high temperature, when the piercing process is completed, as the temperature accumulates and decreases, it contains a small amount of melting. This situation not only reduces the processing quality, but also causes a kind of damage to the workpiece. Therefore, the tool setting shaft adjustment device for CNC EDM piercing machine is required, which has the ability to adjust the workpiece. In the process of drilling, the function of deburring the surface of the workpiece after the end of the processing
