Abstract
A clamp for laser cutting comprises a support. A horizontal adjusting spring and symmetrical horizontal support balls are disposed between the support and a movable support plate. Two clamp parts which are in left-right symmetry are disposed on the movable support. A connection fixing plate of each clamp part is vertically disposed on one side of the same. A spring guide rod fixing plate is disposed between each connection fixing plate and the movable support plate. The included angle alpha of each spring guide rod fixing plate ranges from 30 degrees to 60 degrees. A vertical adjusting spring is sleeved outside each spring guide rod disposed on the corresponding spring guide rod fixing plate. A support frame support board which is movably connected with the upper end of each connection fixing plate is disposed above each vertical adjusting spring. A support part is disposed on each support frame support board. The clamp has the advantages that the clamp has a support function as common clamps and has multiple freedom degrees, petroleum pipes with bending deformation can still be machined by the clamp, petroleum pipe cutting continuity is well guaranteed, and machining efficiency is increased greatly.
Description
Technical field
The present invention relates to a kind of fixture for laser cutting.
Background technology
In recent years, along with Laser Processing is used in industrial circle more and more widely, the laser process equipment that variety of functions is different comes out one after another.Laser cutting machine, laser-beam welding machine and laser marking machine etc. are typically arranged.This just requires design to produce a series of high accuracy, high performance frock clamp is supporting with it.
Because the petroleum pipeline tube wall is thicker, about 8-lOmm, pipeline is longer usually, usually between 8-12m.And the processing stroke of existing laser cutting machine only has about 3-5m, therefore, usually adopts the method for segmentation cutting to process.And Laser Processing belongs to hot-working, and the pipe fitting that this thickening of segmental machining lengthens causes the thermal stress of pipe fitting and the flexural deformation of internal stresses release easily, causes difficulty to processing, and is serious even make the tube bending that processes excessive and scrap.General anchor clamps adopt an end to fix, an end be equipped with actively ball " V ' ' shape piece multidigit point supports pipe, after adjusting to the right place just the movable end with nut handle " v " shape piece tighten up.This anchor clamps rigidity is too strong, on the one hand so that the distortion of workpiece does not have Free up Memory, makes on the other hand the stress distribution of inside workpiece more complicated, is difficult to find rule, is difficult to workpiece is made corresponding adjustment.Therefore, behind the segmental machining part pipe, because the local buckling of pipe distortion, the moment of torsion that the pipe rotation is needed increases rapidly, is easy to cause the deadlock of laser cutting machine rotary part, has greatly damaged the life-span of laser cutting machine.
Summary of the invention
The technical problem that the present invention solves is, a kind of fixture for laser cutting is provided so that petroleum pipeline occur bending and deformation the time still can be processed, guaranteed preferably the continuity of petroleum pipeline cutting processing, greatly improved working (machining) efficiency.
The technical solution used in the present invention is:
A kind of fixture for laser cutting, comprise support, be provided with Level tune spring and symmetrically arranged horizontal support ball between this support and the movable supporting plate, be provided with symmetrical two on the movable supporting plate and clamp parts, each clamps the side that plate is vertically installed in respectively movable supporting plate that is connected and fixed of parts, be connected and fixed and be provided with the spring conductor rod fixed head between plate and the movable supporting plate, 30 °≤α of its angle≤60 °, the spring conductor rod that arranges on the spring conductor rod fixed head is set with the vertical adjusting spring outward, vertical adjusting spring top is provided with the bracing frame gripper shoe that is connected with the movable upper end that is connected and fixed plate, is provided with support member on the bracing frame gripper shoe.
Beneficial effect of the present invention is:
The present invention not only possesses the support function of general chucking appliance system, but also has the multiple free degree so that petroleum pipeline occur bending and deformation the time still can be processed, guaranteed preferably the continuity of petroleum pipeline cutting processing, greatly improved working (machining) efficiency.
Description of drawings
Fig. 1 is structure principle chart of the present invention.
Fig. 2 is the structural representation that clamps parts among Fig. 1.
Fig. 3 is that Fig. 1 is along the cutaway view of A-A line.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment:
As scheme shown in the l, fixture for laser cutting comprises support 13, is provided with two Level tune springs 11 and symmetrically arranged four horizontal support balls 12 between support 13 and the movable supporting plate 10.Level tune spring 11 is formed by the connecting rod serial connection by two springs, and connecting rod also passes the spring Connection Block that lays respectively on support 13 and the movable supporting plate 10.Horizontal support ball 12 is fixed on the panel of support 13.
Be provided with symmetrical two at movable supporting plate and clamp parts 14, its structure for clarity sake, has been left out among the figure and has been connected and fixed plate 8 as shown in Figure 2.Be connected and fixed the side that plate 8 vertically is positioned at movable supporting plate 10, be connected and fixed between plate 8 and the movable supporting plate 10 and be provided with spring conductor rod fixed head 9,30 °≤α of angle between spring conductor rod fixed head 9 and the movable supporting plate 10≤60 °, be fixed with spring conductor rod on the spring conductor rod fixed head 9, vertical adjusting spring 7 is sleeved on this spring conductor rod.Vertical adjusting spring 7 tops are provided with the bracing frame gripper shoe 4 that is connected with the movable upper end that is connected and fixed plate 8 by gripper shoe connecting rod 5.Be provided with support member 2 on the bracing frame gripper shoe 4.Bracing frame gripper shoe 4 can drive bracing frame 3 and support member 2-and rise around gripper shoe connecting rod 5 and swing up and down.
During cutting petroleum pipeline 1, petroleum pipeline rotates according to the requirement of program with certain speed on anchor clamps under the drive of motor, while the shaven head of laser instrument then moves along axial cutting of petroleum pipeline.Like this, just the outer round surface at petroleum pipeline cuts out satisfactory joint-cutting.Because Laser Processing is hot-working, so behind the joint-cutting of having processed some, flexural deformation to a certain degree occurs in petroleum pipeline easily, if using a general end fixes, the anchor clamps of " V " shape piece that ball is housed of one end activity support, be stuck when petroleum pipeline after the distortion is rotated in follow-up process, cause the motor of lathe to burn out.But after using anchor clamps of the present invention, the distortion of petroleum pipeline will " be eaten up ".For instance, if petroleum pipeline deforms in the horizontal direction, the Level tune spring 11 of that petroleum pipeline horizontal direction when rotating will deform, horizontal anomalous movement gripper shoe 10 will swing at horizontal support ball 12, petroleum pipeline still can freely rotate, if petroleum pipeline occurs bending and deformation at vertical direction, the vertical regulating spring 7 of that petroleum pipeline vertical direction when rotating will deform, bracing frame gripper shoe 4 will drive bracing frame 3 and support member 2-and rise around gripper shoe connecting rod 5 and swing up and down, petroleum pipeline still can freely rotate, if petroleum pipeline occurs bending and deformation simultaneously with vertical direction in the horizontal direction, that movable supporting plate 10 and bracing frame gripper shoe 4 will swing together, and petroleum pipeline still can freely rotate.
