Description
Technical field
The invention belongs to technical field of board processing more particularly to a kind of cutting auxiliary devices of the plate circle of contact.
Background technique
Currently, since technical field of mechanical processing and technical field of buildings may require that the round plate of all size, this
The plate at place refers to the metal plate of forging, glass, the standard that technical field of mechanical processing and construction and installation technical field need more
Round plate is chiefly used in the installation of standard device, the positions such as steel construction accessory in industrial premises construction, building construction process.
Such plate has the characteristics that precise requirements are high, size coverage is wide, quantity demand is big.Current existing plate is being cut into
When circle material, by crossing on plate, then cut according to scribing line trace.The cutting task of these plates substantially by
Man-hour manually hand-held cutter device is operated, and a large-scale plate cutting, which generally requires multiple person cooperational, to be completed, and is operated
In the process because of the shake of operator's body or hand, causes the plate accuracy of cutting that cannot meet the requirements, cause resource
A large amount of wastes.The low efficiency operated such simultaneously, operator needs prolonged to keep close with plate in operation process
Distance contact, so that the injury to human body is very big
Chinese patent (CN204700369U) discloses a kind of cutting auxiliary tool of plate circle of contact, including the support being used to support
Device, and the pressure pin of fixed cutter device, the pressure pin may be implemented to stretch by locking device, to realize to circle of contact radius
Adjusting.But the cutting auxiliary tool of the above-mentioned circle of contact does not have measuring function, needs to measure the length for adjusting pressure pin by ruler
Degree, in the process, one is this tool operation can generate large error, the mistake during error and people's measurement from ruler
Difference can seriously affect the accuracy of round plate, and a large amount of round plates is caused to be unable to satisfy the precise requirements of technique and washed in a pan
It eliminates, causes the waste of a large amount of manpower and material；The second is the magnitude range that this tool meets incising circular plate is very limited, nothing
Method is by selecting the combination of different length pressure pin to realize the cutting of a wide range of radius plate.
Summary of the invention
