Abstract
The utility model relates to the field of manual flame cutting, in particular to an auxiliary device for the manual flame cutting of a circular hole in a steel product. The auxiliary device is characterized by comprising a base, a rolling bearing and a rotary table, wherein an outer ring of the rolling bearing is connected with the base; an inner ring of the rolling ring is connected with the rotary table; a cutting torch hole is formed on a radius part of the rotary table and opposite to the circular hole to be cut; a reference hole is formed in the center of the rotary table; a rotary handle is arranged on the rotary table; and a magnet is arranged at the bottom of the base. Compared with the prior art, the auxiliary device is simple and practical and can be flexibly and conveniently used, the manual flame cutting of the circular holes with different apertures in a steel plate at different cutting positions can be realized on a steel structure device under the condition of engineering maintenance, and the quality of the manual flame cutting can reach the quality of numerical control cutting.
Description
Technical field
The utility model relates to Manual flame cutting field, relates in particular to a kind of servicing unit of Manual flame cutting steel circular hole.
Background technology
At present, the Manual flame cutting of steel circular hole is the difficult point in Construction of Steel Structure and the engineering maintenance, the drilling operation has realized Numerical control cutting and digital control hole drilling substantially in the production of modernization structure steel fabrication, but in particular cases still need hand cut at some: such as steel construction in the hole that needs interim cutting than macropore and in the overhaul of the equipments process that is not suitable for machining that needs secondary operations after the erection welding, because to improving constantly of work progress quality requirement, directly the Manual flame cutting can't be satisfied quality and required precision.
Summary of the invention
The purpose of this utility model is to provide a kind of servicing unit of Manual flame cutting steel circular hole, guarantees to realize flexibly and easily high-quality steel circular hole hand cut in the situations such as steel structure device and engineering maintenance.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of servicing unit of Manual flame cutting steel circular hole, comprise pedestal, rolling bearing and rotating disk, the outer ring of rolling bearing is connected with pedestal, and the inner ring of rolling bearing is connected with rotating disk, corresponding circle hole radius to be cut place is provided with the cutting torch hole on the rotating disk, and center of turntable is provided with datum hole.
Described rotating disk is provided with swing handle.
Described base bottom is provided with magnet.
Compared with prior art, the beneficial effects of the utility model are: simple and practical, flexible and convenient to use, in the situations such as steel structure device and engineering maintenance, can realize various different pore sizes, carry out Manual flame cutting steel plate circular hole at different cutting positions, and cut quality can reach the effect of Numerical control cutting.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
Among the figure: the 5-swing handle 6-magnet 7-datum hole of 1-pedestal 2-rolling bearing 3-rotating disk 4-cutting torch hole
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, it is the servicing unit example structure schematic diagram of a kind of Manual flame cutting of the utility model steel circular hole, comprise pedestal 1, rolling bearing 2 and rotating disk 3, the outer ring of rolling bearing 2 is connected with pedestal 1, the inner ring of rolling bearing 2 is connected with rotating disk 3, corresponding circle hole radius to be cut place is provided with cutting torch hole 4 on the rotating disk 3, and center of turntable is provided with datum hole 7.Pedestal 1 bottom is provided with magnet 6.Rotating disk 3 is provided with swing handle 5.
Need to cut the hole of three different radiis such as embodiment, radius is respectively R1, R2 and R3, the center of circle in the hole to be cut on the steel is overlapped with datum hole 7, magnet 6 is fixed this device and steel, burning torch is lighted, cutting torch is put into the cutting torch hole 4 of relevant radii, utilizes swing handle 5 to rotate rotating disk and can cut.Can realize various apertures by this device, the cutting of the circular hole flame of various positions, cutting effect can be good as the surface trimming.
