Said invention can ensure continuity for cutting petroleum pipe.
Description
Technical field
The present invention relates to a kind of laser process equipment, specifically a kind of anchor clamps that are used for laser cutting are particularly useful for the laser cutting of petroleum pipeline.
Background technology
In recent years, along with Laser Processing more and more widely application in industrial circle, 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 8-10mm, pipeline is longer usually, usually between 8-12m.And the processing stroke of existing laser cutting machine has only about 3-5m, therefore, adopts the method for segmentation cutting to process usually.And Laser Processing belongs to hot-working, and the pipe fitting of this thickening of segmental machining lengthening causes the thermal stress of pipe fitting and the flexural deformation that internal stress discharges 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, and " V " shape piece multidigit point that an end is equipped with ball versatilely supports pipe, and the back of adjusting to the right place just tightens up the movable end of " V " shape piece with nut.This anchor clamps rigidity is too strong, makes the distortion of workpiece not have Free up Memory on the one hand, makes the stress distribution of workpiece inside more complicated on the other hand, 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 damaged the life-span of laser cutting machine greatly.
Summary of the invention
The object of the invention is to provide a kind of anchor clamps that are used for laser cutting that can overcome above-mentioned defective, and it has certain non-deformability, is particularly useful for cutting in the petroleum industry laser cutting machine equipment that all size is especially thickeied the lengthening seamless steel pipe.
For achieving the above object, the anchor clamps that are used for laser cutting comprise support and support member, be provided with horizontal regulating spring and symmetrically arranged horizontal support ball between support panel and the movable supporting plate, movable supporting plate is provided with symmetrical two and clamps parts, clamp the side that plate vertically is positioned at movable supporting plate that is connected and fixed on the 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 fixed head is provided with the vertical adjusting spring, its top is provided with and is connected and fixed the bracing frame gripper shoe of the upper end flexible connection of plate, and the bracing frame gripper shoe is provided with support member.
Above-mentioned support member can adopt ball or bearing.
This sleeve clamp system not only possesses the support function of general chucking appliance system, but also has the multiple free degree, make petroleum pipeline occur bending and deformation the time still can be processed, guaranteed the continuity of petroleum pipeline cutting processing preferably, improved working (machining) efficiency greatly.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structure principle chart of the present invention;
Fig. 2 is for clamping the structural representation of parts among Fig. 1;
Fig. 3 is the cutaway view of Fig. 1 along the A-A line.
The specific embodiment
As shown in Figure 1, be provided with two horizontal regulating springs 11 and symmetrically arranged four horizontal support balls 12 between support 13 and the movable supporting plate 10.Horizontal regulating 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.
Movable supporting plate is provided with symmetrical two and clamps parts 14, and its structure for clarity sake, has been left out among the figure and is 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 flexibly connects by gripper shoe connecting rod 5 and the upper end that is connected and fixed plate 8.Bracing frame gripper shoe 4 is provided with support member 2.Bracing frame gripper shoe 4 can drive bracing frame 3 and support member 2 swings up and down around gripper shoe connecting rod 5 together.
Support member 2 can adopt ball or bearing.
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 takes place 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 horizontal regulating spring 11 of that petroleum pipeline horizontal direction when rotating will deform, horizontal anomalous movement gripper shoe 10 will swing on 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 swings up and down around gripper shoe connecting rod 5 together, 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 be swung together, petroleum pipeline still can freely rotate, and makes anchor clamps of the present invention have good practicality.
