Abstract
The invention relates to a device for machining the sealing face of a manhole cover plate on a numerical control milling machine and a clamping method. When the sealing face of a traditional manhole cover plate is machined on the numerical control milling machine, a workpiece must be tightened on a working table, and the tightening mode is characterized in that box iron needs to be welded to the back face of the workpiece, the workpiece is supported on the working table of the milling machine through cushion blocks, the box iron penetrates through a steel plate to pull the workpiece downwards, and then the workpiece is fastened to the working table through fasteners; due to the fastening mode, the manhole cover plate is prone to deformation after being machined, and product quality is influenced. The device comprises a working table (4); the upper plane of the working table (4) is connected with the lower plane of a magnetic suction cup (3) through a T-shaped bolt, the upper plane of the magnetic suction cup (3) is magnetically connected with the manhole cover plate (1), and the sealing face (2) is arranged on the outer side of the upper plane of the manhole cover plate (1) and attached to a milling cutter (6). The scheme is used for the device for machining the sealing face of the manhole cover plate on the numerical control milling machine.
Description
technical field:
the present invention relates to a kind of cover plate for manhole on CNC milling machine, process sealing surface device and chucking method.
background technology:
when sealing surface processed by traditional cover plate for manhole on CNC milling machine, must on the table by tight for workpiece handle, tight mode be need back of work welding channel-section steel, milling machine table supports workpiece with cushion block, workpiece is pulled down through channel-section steel with steel plate, be tightened on workbench with securing member handle again, this fastening means easily makes cover plate for manhole add post-construction deformation, affects product quality.
adopt that traditional there are the following problems tight mode, the careful front cover of NC Milling, finds after pulling down screwde on, originally processes the sealing surface of having put down and occurs distortion, distortion is at about 0.2mm, the careful front cover of NC Milling, when removing auxiliary channel-section steel, adopts gas cutting to assist channel-section steel, reconditioning scarfing mode, after operation there is again distortion in finder's blind patch, distortion is at about 0.3mm, and twice distortion is accumulated at about 0.5mm, affects the sealing effectiveness of sealing surface.
summary of the invention:
the object of this invention is to provide a kind of cover plate for manhole on CNC milling machine, process sealing surface device and chucking method.
above-mentioned object is realized by following technical scheme:
