Description

The portable pipe beveling machine

Affiliated technical field

The utility model relates to a kind of portable pipe beveling machine, the bigger beveling machine of especially a kind of suitable conduit scope.

Background technology

At present, existing tube groove machine, because the restriction of its structure, its diameter range that adapts to pipeline has certain limitation. when multiple pipeline is carried out groove, select the beveling machine of multiple model possibly for use, reduced efficient, increased cost.

The patent No. ZL200420104471.9 of State Intellectual Property Office of the People's Republic of China discloses a kind of beveling machine.Its tension mechanism adopts the mode tensioner of tightening piece, voussoir seat and voussoir at pipe interior.Because the sliding scale of voussoir is limited, when surpassing certain limit, different pipe diameters to realize fixing by the replacing piece that rises, complex operation, efficient is lower.This structure also defines the size of cutter diameter simultaneously, causes this adaptable pipe diameter scope of beveling machine institute less.Working ability is less.

The ZL of the State Intellectual Property Office of the People's Republic of China patent No. 00255833.5 discloses a kind of beveling machine.Its tension mechanism is provided with fixture block and support thereof more than three groups or three groups, the fixture block support is made of two bars that are hinged at the middle part, one rod member, one end and moving axis cover are hinged, the other end and workpiece fixture block are hinged, another rod member one end and core sleeve are hinged, and the other end is hinged with the bearing pin that is located in the workpiece fixture block guide groove.Because the mode that has adopted two bars to be hinged at the middle part makes it must use workpiece grip mechanism and pipeline tensioner, has increased the weight of beveling machine.Production technology is comparatively numerous and diverse, has increased production cost.Unlike material, the groove of different pipe diameters need carry out under the cutting speed that is fit to.More than 2 patented products because speed can not be adjusted, just limited the kind of processed pipeline material and the diameter range of pipeline.

Summary of the invention

In order to overcome the technical deficiency of existing tube groove machine, the utility model has adopted the motor of a kind of adjustable speed and torque and a kind of new tension mechanism is provided, and makes a machine can be suitable for the tube groove of caliber in a big way.Both solve the different pipelines replacing different model beveling machines and the loaded down with trivial details of piece of rising in certain caliber scope, saved time and financial cost for the user simultaneously.Improved efficient.In order to overcome the deficiency of existing tube groove machine technology, the utility model solves the technical scheme that its technical problem adopts and is: adopt adjustablely turn round, the motor of speed governing.So that satisfy, the groove of the different pipe diameters that machining unlike material pipeline and span are bigger is to the requirement of speed.

Globoidal structure is all adopted in its piece outside of rising, and is a plane at the tube wall contact-making surface with processed pipeline.Guaranteed the firmness of tensioner.This machine adopts three groups of support bars, every group of support bar is connected on corresponding of two corner blocks, connect the piece that rises on every group of support bar, three piece tensioners simultaneously that rise, 3 determine a plane, guaranteed that its main shaft is vertical with the machined surface of processed pipeline, guaranteed the concentric of its main shaft and pipeline.

The tension mechanism structure is made up of main shaft (the main shaft below is leading screw), corner block, support bar, the piece that rises.Wherein Shang Mian corner block does not have the local of screw thread and can center on main shaft to rotate in the middle of being connected main shaft by circlip, and following corner block links to each other with leading screw by the screw thread of centre bore.Three of corner blocks are respectively connecting 1 group of support bar, and every group of support bar connects by the piece that rises.Corner block moved up and down under the rotation of axle drove, and made support bar drive rise piece tensioner or contraction in a big way.Avoided caliber in more among a small circle, just to need to change the piece that rises.This swelling device has solved the problem of beveling machine adaptation tube groove in a big way equally simultaneously, by the piece fixed-piping that rises, neutral and fastness all is greatly improved, and makes structure simpler, has saved cost simultaneously, has improved operating efficiency.

The beneficial effects of the utility model are that simple in structure, a machine both can adapt to the pipeline of unlike material and the groove of wide range of diameters, need not change the piece that rises in tensioner.
