Abstract

The utility model discloses a welding mechanical hand, which is characterized in that a long spring is arranged in the outer shell; two spring connectors are arranged in two ends of the spring; a hole is arranged in the spring connector; at least three insulating frames are arranged in the external end of the long spring; a bending tube is arranged in one end of the spring connector. Automatic operation is realized with the combination of the utility model and the mechanical hand for the welding flux transportation. Therefore the deep hole welding with the diameter of 300mm to 600mm and the depth of 6m is realized. No distortion occurs when the temperature is less than 250 DEG C after long period work. The utility model has simple structure and light weight, which resolves the difficulties of repairing and processing in the wearing part of the deep hole for many years.

Description

Welding manipulator

Technical field:

The utility model relates to the technical field of welding equipment, is vitals on the deep hole built-up welding machine, specifically a kind ofly is used to replace artificial the deep hole welding manipulator that can't finish.

Background technology:

For after the deep-borehole component wearing and tearing, how to repair and re-use, one to the important topic of inquiring into, study, developing for people.Several years ago Shanghai factory to external import a dark mouthful built-up welding machine (below 1.2 meters, and being domestic most advanced) through on-the-spot investigation, there is following problem in it:

1,1.2 meters and following deep hole built-up welding can only be solved, deep hole built-up welding more than 1.2 meters can not be solved;

2, it is unreasonable that structure is robbed in weldering, this structure adopt three long be 0.4 meter, diameter is the hole of 0.04 meter the middle 6mm of boring of garden post steel, and form (three length overall 1.2 meters) with thread connection, so just causing weldering to rob can not be long, because oversize, it is unstable to cause weldering to rob the head location, in welding process, rob the head shake, cause welding quality to descend;

3, since this structure to cause weldering to rob weight heavier, and use thread connection, rob saggingly, and fragile so in use can cause, can use after often will keeping in repair.Can not under 250 ℃ of temperature, work long hours.

Summary of the invention:

The purpose of this utility model is to provide a kind of welding manipulator, and it can adopt the manipulator mode of using, and substitutes the deep hole built-up welding that manually can't carry out, and realizes automated production.

The technical solution of the utility model is achieved in that welding manipulator, it mainly comprises the welding gun shell, the bend pipe that is connected with the welding gun shell, be contained in the ignition tip on the bend pipe, it is characterized in that: in the welding gun shell, adorn a long spring, the spring coupling is housed, in the spring coupling, be provided with the hole at the two ends of long spring, in the outer end of long spring at least three insulating frames are housed, bend pipe are housed at an end of spring coupling.

The utility model matches with flux delivery manipulator (separate case application), can realize automation mechanized operation, can solve diameter is 300mm to 600mm, length is the deep hole welding of 6m, it is indeformable to work long hours under 250 ℃, and simple in structure, in light weight, solve the reparation of deep hole wear-out part for many years, processed this difficult problem.

Description of drawings:

Fig. 1 is the structural representation of the utility model one embodiment

The specific embodiment:

The utility model will be further described below in conjunction with drawings and Examples.

The utility model mainly comprises welding gun shell 5, the bend pipe 2 that is connected with welding gun shell 5, be contained in the ignition tip 1 on the bend pipe 2, it is different from prior art and is: adorn a long spring 7 in welding gun shell 5, at the two ends of long spring 7 spring coupling 3 is housed, in spring coupling 3, be provided with hole 11, in the outer end of long spring 7 at least three insulating frames 6 are housed, end at spring coupling 3 is equipped with bend pipe 2, in the enforcement in order to make the fixed-site of spring coupling and insulating frame, skin at spring coupling 3 is installed coupling overcoat 4, between spring coupling 3 and insulating frame 6, insulating sleeve 8 is housed, for the ease of regulating the degree of tightness of long spring 7, adorn a bearing 10 and seal nut 9 at the other end of spring coupling 3, on the garden 11 spring insulating frames 6 are installed altogether outside the spring of present embodiment between the spring coupling 3 at two ends, shape is evenly distributed, the external diameter of insulating frame equates with the coupling overcoat, between spring coupling and spring insulating frame, install 12 altogether and thoroughly do away with the edge sleeve pipe, make 11 spring insulating frame fixed-site, coupling overcoat and spring insulating frame are installed in the shell, and their internal diameter matches with the shell of welding gun.

Owing to select the material of the required usefulness of welding manipulator parts for use, and must adaptation under 250 ℃ temperature, work long hours indeformable, and this welding manipulator has an overlength, the characteristics of ultralight, therefore rob length at weldering, the aperture is little (can't to be processed, endoporus must be wear-resisting, intensity is arranged, hardness, characteristics such as heatproof, welding wire is constantly operation in the hole, cause welding wire and endoporus constantly to rub), having designed one among the embodiment is the spring steel machine-shaping of 3mm with diameter, quench, hardness is the small-bore spring of the overlength of HR50 (internal diameter is 6mm), the assembling back is strong, when welding wire passes through, because bore wall is made up of many circular arcs, welding wire and bore area contact-making surface are little like this, welding wire is good by time spring property, be difficult for being worn, concrete ignition tip 1 and bend pipe 2 thread connection of being fixedly connected as, bend pipe 2 and spring coupling 3 thread connection, spring coupling 3 is stationary fit with coupling overcoat 4, coupling overcoat 4 and welding gun shell 5 tight fits, spring coupling 3 and spring 7 are by thread connection (thread size is exactly a spring appearance and size), insulating sleeve 8 and spring 7 are movingly, spring insulating frame 6 and welding gun shell 5 are movingly, insulating frame 6 and spring 7 movingly, insulating frame 6 and insulating sleeve 8 movingly, welding wire is sent into the hole of spring coupling in the use by wire feeder, again through the spring endoporus, arrive ignition tip 1 outlet at last, this welding manipulator length is 3.6 meters, and diameter is 0.05 meter.
