Abstract
The utility model relates to a flexible automatic centering clamping device which is used for clamping pipe joints, and the clamping device is composed of a plurality of arced clamping components of which the cross sections are arced, the spliced cross sections are annular and the arced clamping components are made of rigidity material. The arced clamping component can form a flexible reference inner circular surface which is convenient to be covered by the clamping pipe joints after splicing, the cross section of the arced clamping component is at least provided with a crescent-shaped cavity type flexible slot which is opened to the inner side surface of the arced clamping component. A flexible deformation zone can be formed between the flexible slot and the inner side surface of the arced clamping component and is convenient to absorb the local deformation of clamped pipe joints, and the flexible slots are uniformly distributed on a ring belt of the clamping device and a central shaft after the splicing of the arced clamping components. The utility model can automatically absorb the local deformation quantity of the pipe joints with a clamping force function, effectively eliminate eccentricity error generated from the local deformation of the pipe joints and keep the accurate centering of the clamping device and the utility model can specially satisfy the automatic precise welding requirements of sealing welding guns.
Description
Technical field
The utility model 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.
Technical background
In the pipe fitting automatic welding technique, the accurate positioning requirements of soldered pipe fitting is very high, and 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 utility model 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.
The technical solution of the utility model is achieved in that
A kind of flexible automatically centering fixture, be used for the clamping pipe fitting, 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 further improvement of the utility model, this each arc folder has identical shaped section, and this each flexible slot has identical shaped section.
As further improvement of the utility model, 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 further improvement of the utility model, this arc folder is that metal material is made.
The beneficial effects of the utility model:
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.

Specific embodiment
Embodiment: be further described below in conjunction with Fig. 1:
A kind of flexible automatically centering fixture, be used for the clamping pipe fitting, 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.The flexible automatically centering fixture that using the utility model provides can absorb the local deformation amount along each different directions of pipe fitting circumference in the certain limit.
Claims (4)
