Description

A kind of multi-functional automatic line cutter sweep

It is anchor point with the garden heart that the utility model belongs to a kind of, does the automatic line of garden week curvilinear motion, blanking cutting class instrument.

In pressure visitor's device manufacturing and pipeline installation process, often meeting some is line, the blanking cutting work that anchor point is done garden week curvilinear motion with the garden heart.The for example line of end socket end face, pipeline end face and equipment upper connecting tube tapping, operations such as blanking and bevel cut.The conventional pipelines baiting method: be on a soft-body, as malthoid and so on, use compasses, ruler marks the plane outspread drawing of pipeline, presses model under the developed curve, more counter being rolled in of model is marked required blanking line of cut on the pipeline.Then by the manual line cutting stock of pressing.This method blanking error is big, and the cut surface precision is low, time-consuming taking a lot of work.In addition at end socket end face baiting method: be the general SBI type end socket automatic gas cutting machine that adopts Changshu City electroplating equipment wielding machine factory to produce, analyze this machine from its operation principle and mainly have following deficiency: first this machine is that required cutting processing end socket is put on three rolling support points on the end socket automatic gas cutting machine rotating disk.Find out the horizontal end face of end socket by end socket weight, like this owing to act on the end socket outer wall rubbing on three support points by the power difference, some end sockets often occur and be cut inclined to one side phenomenon, second because the end socket volume is big, Heavy Weight, therefore the volume of SBI end socket automatic gas cutting machine is big, driving motor power is big, the manufacturing cost height.

The purpose of this utility model is: provide a kind of and can directly pass through end socket, the cylindrical camber line of pipeline, accurately find out their center of circle or axial line, then with the center of rotation anchor point of this circle center type axial line as multi-functional automatic line cutter sweep.The end socket that is cut or the axial line of pipeline are overlapped with multi-functional automatic line cutter sweep axial line, thereby realized concentric co-axial motion between the two.Fundamentally reach line, cutting accuracy height, error be little, this device has that volume is little, widely applicable, easy to use, low cost of manufacture simultaneously.

The utility model is achieved in that

With reference to Fig. 1, it is provided with a scale 2 and at the mid point of scale 2 horizon equipment 1 and laser alignment device 3 scales 2 two ends is housed and has on two locating pieces, 1 locating piece 1 fastening bolt 6 is arranged.

With reference to Fig. 2, install and be equipped with a central turnplate 8 and on 7 of micromachines a pinion 11 be housed and engage with gear wheel on the gear positioning disk 9 being connected with a ground way card 6 horizon equipments 17 and miniature variable speed electric motors, particularly 7 on the central turnplate 8, central turnplate 8 links to each other with gear positioning disk 9 with thrust bearing by bolt.The center, lower end of gear positioning disk 9 has been installed 12 3 supporting legs 12 of three supporting legs that can stretch are installed on the inclined-plane, lower end of laser alignment device 10 gear positioning disks 9 is to be contained in the semi-girder 5 by the semi-girder 4 that three positive left-hand threads 13 link to each other with being connected of three magnet locating pieces 14, and semi-girder 5 is fixed on the central turnplate 8 by slipway clamp 6.Semi-girder 4 connection displacement bars 3 displacement bars 3 connection springs benefits are tasted device 2 springs benefit and are tasted device 2 connection cutting torch 1 and directive wheels 15.

It is line, the cutting tool that fixed point is done the circular order motion with the center of circle that advantage of the present utility model just is to do end socket or pipeline etc.It is not limited by the construction site, easy to use, simple to operate, volume is little, simultaneously the line, the cutting accuracy height.

Concrete structure of the present utility model can be shown by following embodiment and accompanying drawing.

Accompanying drawing 1: be end socket alignment working state figure of the present utility model.

Accompanying drawing 2: be end socket line cutting working state figure of the present utility model.

With reference to Fig. 1 is the end socket alignment, and it is to utilize on the circular arc look for the principle in the center of circle to design at any 3.It is provided with scale 2, in scale 2 central spot horizon equipment 1 and laser alignment device 3 is installed, and is marked with size scale at scale 2.Be provided with two locating pieces 1 at scale 2 two ends, two ends locating piece 1 abutted against on the end socket outer wall center of adjusting scale 2 to the distance of two ends locating piece when equal, fastening bolt 6, find out scale 2 and end socket 5 same levels by scale 2 upper end horizon equipments 1 again, find out the end socket summit by laser alignment device 3 on end socket 5 again, the summit of end socket or end socket axial line have just accurately been found out like this.

With reference to Fig. 2, be put in the end socket according to the above-mentioned end socket summit of finding out or the end socket axial line cutting mechanism of will ruling automatically, by three magnet locating pieces 14 this mechanism is fixed on the end socket inwall, adjust this mechanism by the positive left-hand thread on three supporting legs 12 13 again, make horizon equipment 17 and end socket 16 axialities and levelness, that is to say to adjust to make laser alignment device 10 and end socket summit projection horizontal registration.The rotary middle spindle of so just having finished this mechanism overlaps consistent with the end socket axle.Making that this mechanism and end socket are organic combines as a whole, and satisfies the end socket cutting-height by the height of regulating displacement bar 3 again, in order to dwindle this mechanism's volume.The utility model has adopted the semi-girder structure, and it is to satisfy different end socket 16 diameter requirements by semi-girder 5 and stretching of semi-girder 4.Simultaneously since end socket in manufacture process error or local deformation, this device has been taked spring to mend to taste device 2, it is by baffle plate 20, spring 19, key 18, telescopic arm 17 is formed.Owing to give 19 1 pressure of spring in advance, make telescopic arm 17 inwardly compress certain distance like this.This distance is mainly used to mend tastes the radial displacement that is produced because of end socket foozle and local deformation, makes directive wheel 15 all the time near end socket 16 inwalls.Thereby reaching cutting torch 1 remains a constant distance with cut surface and has so fundamentally guaranteed line, the quality of cutting.
