Drilling mechanism for upper shell of wire connecting box

Abstract

The invention discloses a drilling mechanism for an upper shell of a junction box, which includes a frame, a main support frame is fixed on the top surface of the middle part of the top plate of the frame, the middle part of the top plate of the main support frame has a main through groove, and the main support frame Lifting cylinders are fixed on both sides of the top plate, the push rod of the lifting cylinder passes through the top plate of the main support frame and the upper connecting plate is fixed, the two sides of the middle top surface of the upper connecting plate are fixed with lifting support frames, and the lifting support frame The lifting motor is fixed on the top plate, the bottom end of the vertical screw is hinged on the upper connecting plate, the top end of the vertical screw is hinged on the top plate of the lifting support frame, the output shaft of the lifting motor is a spline shaft, and the spline shaft is inserted into the sleeve In the spline hole that the top of the vertical screw rod has, the lifting plate is screwed in the two vertical screw rods, and the middle top surface of the lifting plate is fixed with a drilling motor. It can fix the workpiece and ensure that its bottom and top surfaces are supported, and realize automatic drilling to ensure the quality of drilling.

Description

Technical field: [0001] The invention relates to the technical field of hardware component manufacturing equipment, and more specifically relates to a drilling mechanism for an upper casing of a junction box. Background technique: [0002] The existing workpiece (the upper shell of the junction box) generally needs to be drilled, but the shell is relatively thin, so it needs to be internally supported and externally fixed during installation, which requires a specific fixed clamping mechanism, but it is not currently available. Without this structure, it can only be clamped and fixed by combining multiple parts, which is very troublesome and inefficient. Moreover, manual drilling is required, which easily deforms the workpiece. Invention content: [0003] The purpose of the present invention is to aim at the deficiencies of the prior art, and provide a kind of drilling mechanism for the upper casing of the junction box, which can process and fix the workpiece and ensure th...
