Abstract
The flexible automatically centering fixture for clamping pipe features that it consists of arced clamping pieces of rigid material and capable of splicing one ring to cover the pipe. Each of the arced clamping pieces has flexible slot in the inner side to form flexible deforming part to absorb the local deformation of the clamped pipe. The flexible automatically centering fixture can absorb the local deformation of the clamped pipe for precise centering, and is especially suitable for automatic precise welding with sealed welding torch.
Description
Technical field
The present invention relates to the self centering anchor clamps of a kind of clamping pipe fitting, particularly relate to a kind of can overcome be held the pipe fitting local deformation, keep being held the pinpoint flexible automatically centering fixture of pipe fitting, be specially adapted to satisfy the accurate welding requirements of sealing welding gun.
Background technology
In the pipe fitting automatic welding technique, very high to the accurate positioning requirements of weld-end fittings, in order to guarantee pipe fitting accurately welding automatically, special requirement realize various seal weldings, must guarantee pipe fitting in whole automatic welding process, and centered positions is correct.
Yet the existing outer surface of pipe fittings that is held is not absolute circular face, can cause like this to be held pipe fitting and to depart from central shaft in the welding rotation process automatically, and it is incorrect to feel relieved.After pipe fitting is held simultaneously, can produce local deformation (as ovalizing deflection), also will cause centering inaccurate.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of flexible automatically centering fixture, these anchor clamps can absorb the distortion of pipe fitting automatically, effectively eliminate the nonconcentricity error that produces because of the pipe fitting local deformation under the clamping force effect, keep the anchor clamps precision centering, satisfy accurate welding requirements.
Technical scheme of the present invention is achieved in that
A kind of flexible automatically centering fixture, be used for the clamping pipe fitting, it is characterized in that, these anchor clamps are curved by a plurality of sections, spliced section is the capable folder composition of arc that circular rigidity material is made, this arc folder splicing back forms is convenient to coat the flexible benchmark inner headed face that is held pipe fitting, the capable folder section of this arc has one at least and is waist shape, cavity type flexible slot to this arc folder medial surface opening, form the plastic deformation district between this flexible slot and this arc folder medial surface, be convenient to absorb and be held the pipe fitting local deformation, and spliced each flexible slot of this each arc folder is evenly distributed on the endless belt with the concentricity axle of these anchor clamps.
As a further improvement on the present invention, this each arc folder has identical shaped section, and this each flexible slot has identical shaped section.
As a further improvement on the present invention, these anchor clamps are made up of the arc folder of two semi-ring faces, this two arcs folder has several cavity type flexible slots respectively, and the spliced section of this two arcs folder forms these several flexible slots and is evenly distributed on the endless belt with the concentricity axle of these anchor clamps.
As a further improvement on the present invention, this arc folder is that metal material is made.
Beneficial effect of the present invention:
These anchor clamps are made up of several arc folders, and the flexible benchmark inner headed face that this arc folder splicing back forms coats the pipe fitting that is held, and clamps pipe fitting simultaneously under the effect that adds clamping force.Because the effect of clamping force, this pipe fitting can produce local deformation, and this local deformation amount will be pushed the opening waist shape cavity type flexible slot that is provided with by this arc folder, thereby absorb this local deformation amount, and the centering that has guaranteed to be held pipe fitting is correct.
Description of drawings
Fig. 1 is a section structure schematic diagram of the present invention
Specific embodiment
Be further described below in conjunction with accompanying drawing 1:
A kind of flexible automatically centering fixture, be used for the clamping pipe fitting, it is characterized in that, these anchor clamps are curved by a plurality of sections, spliced section is capable folder 1 composition of arc that circular rigidity material is made, this arc folder splicing back forms is convenient to coat the flexible benchmark inner headed face 2 that is held pipe fitting 6, the capable folder section of this arc has one at least and is waist shape, cavity type flexible slot 4 to this arc folder medial surface opening 3, form plastic deformation district 5 between this flexible slot and this arc folder medial surface, be convenient to absorb and be held the pipe fitting local deformation, and spliced each flexible slot of this each arc folder is evenly distributed on the endless belt with the concentricity axle of these anchor clamps.This each arc folder can have identical shaped section, and this each flexible slot also has identical shaped section, and this arc folder can be made for metal material.
As shown in Figure 1, in the present embodiment, these anchor clamps are made up of the arc folder of two semi-ring faces, four identical plastic deformation districts of section configuration be evenly distributed in the coaxial annulus of this flexibility benchmark inner headed face on.
The operation principle of this flexible automatically centering fixture is such: when the pipe fitting that is held produces distortion in the circumference part, this flexible slot absorbs the distortion of pipe fitting automatically under the effect of clamping force, effectively eliminate the nonconcentricity error that produces because of the pipe fitting local deformation, keep the precision centering of these anchor clamps, thereby satisfy accurate welding requirements.Use flexible automatically centering fixture provided by the invention and can absorb the interior local deformation amount of certain limit along each different directions of pipe fitting circumference.
Claims (4)
