Description
Technical field
It the utility model is related to a kind of welding positioner.
Background technology
Positioner be it is a kind of it is general, efficiently to realize the common welding equipment based on girth welding, be by workpiece
Revolution, tilt, and the weld seam on workpiece is placed in the Welding positioner tool of favourable welding position.Can adapted argon arc welding machine (fill silk or
Do not fill silk), gas metal-arc welder (C02/MAG/MIG welding machines), plasma welding machine, the welding machine such as laser-beam welding machine, and can
Robot welding system is formed with its machine.Traditionally it is mainly used for the upset of the non-elongate workpiece such as rack, engine base, flange, end socket
Deflection welding, cutting, with the development of Numeric Control Technology, a part of the positioner as multi-shaft interlocked equipment, starts to apply
With the welding and cutting of space curved surface workpiece, the axisymmetric workpiece such as non-length such as sphere, vertebra face, class vertebra face is especially largely used to
Automatic welding of shape workpiece etc..
Positioner is mainly made of rotating head, modified gear and controller.Rotating head rotating speed is adjustable, displacement
Mechanism is used to adjust angle of inclination, welding gun head liftable.
Laser melting coating is similar to plasma surfacing, is a kind of continuous technique for overlaying, is that one kind of laser welding technology is prolonged
Stretch.Laser melting coating refers to place selected coating material through laser spoke on by cladding matrix surface with different adding material modes
It is extremely low that dilution factor is formed according to being allowed to melt at the same time with matrix surface a thin layer, and after quickly solidifying, with matrix into metallurgical binding
Face coat, significantly improves wear-resisting, anti-corrosion, heat-resisting, anti-oxidant and electrical characteristic the process of matrix surface, so as to reach
Surface modification or the purpose repaired, had not only met the requirement to material surface particular characteristic, but also saved substantial amounts of noble element.
Ball for ball valve, the part of irregular cone are in order to improve the wearability on surface, corrosion resistance, impact resistance, improve the property of part
Can, increase the service life of part, laser melting coating can be used to carry out surface peening.
Generally use is coaxial in laser melting coating or paraxonic automatic powder feeding system, in order to ensure powder feeding position and laser in process
Focus does not deviate, and process powder sending quantity and powder using efficiency stable and consistent, and laser light incident is generally required in process
The angle of workpiece is constant, so adapting to the incidence angle of laser by varying the posture of workpiece.
And traditional positioner, due to lacking rotation axis axial-adjustment unit, realize rotating head central axis with
The central axis orthogonal points of modified gear, processing starting point, 3 points of coincidences of benchmark numeral origin of workpiece are then extremely difficult.It is solved
Method certainly is usually that directly axial direction of the adjustment workpiece on chuck is loaded position, or does a dedicated positioning work that is loaded
Dress.
Directly adjustment is loaded the method for position, should by work piece and chuck, again so that the central point of workpiece with
The center line alignment of modified gear, since the distance of its adjusting is limited, and is rule of thumb adjusted, not clear and definite
Adjusting quantity, thus, it can be difficult to even accurately the center of workpiece can not be adjusted onto the center line of modified gear, because
This, when its laser melting coating, causes the laser melting coating of sphere or the conical surface uneven, influences performance, and adjusts and expend time length, pole
The big efficiency for influencing work.
The dedicated positioning tool that is loaded is a kind of effective means for batch machining, does not apply to single-piece economically and adds
Work.And rotation axis axial length is caused to lengthen because addition of the dedicated positioning tool that is loaded, it is desirable to which welding equipment has bigger
Effective impulse stroke, the installation space of bigger, simultaneously because the arm of force lengthens, the higher proposed to the bearing capacity of modified gear
Requirement, be not a kind of scheme of economical rationality.
The content of the invention
To solve the above problems, the purpose of this utility model is to provide one kind can welding when effectively, quick regulation
Workpiece zero point is overlapped with positioner orthogonal points, simplifies sphere or the conical surface movement locus when curved surface axisymmetric workpiece is welded, and is improved
The welding positioner of welding efficiency and welding quality.
To achieve the above object, the utility model provides following technical solution：A kind of welding positioner, including swing arm
Formula rotating head and modified gear, the arm oscillating type rotation head central axis is orthogonal with the central axis of modified gear, described
Arm oscillating type rotation head and the modified gear are driven by motor respectively, it is characterised in that the modified gear, which is equipped with, to be slided
Rail, the sliding block being matched therewith is equipped with the slide, the arm oscillating type rotation head is connected with the sliding block, described
Sliding block is connected with transmission device.
The transmission device has screw rod, and the screw rod is rotatably installed on slide, is set on the sliding block
There is threaded hole, the screw rod is passed through out of described threaded hole.
The slide section is in dovetail shaped, and the sliding block is equipped with the dovetail groove to match with the slide, described
Dovetail groove on sliding block is caught on the slide.
This structure of the utility model, after workpiece is installed on arm oscillating type rotation head, then by sliding block along slide
Mobile adjustment, it is the central axis of the digital origin and modified gear of workpiece is laterally aligned, it is easy to so that the numeral of workpiece is former
Put and be changed into the central axis of mechanism and overlapped with the central axis orthogonal points of arm oscillating type rotation head, its is easy to operate, and adjusting can
Lean on, simplify sphere or the conical surface movement locus when curved surface axisymmetric workpiece is welded, improve welding efficiency and welding quality.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and detailed description.
Fig. 1 is the structure chart of the utility model；
After Fig. 2 rotates 90 degree for the utility model arm oscillating type rotation head and take the structure chart after workpiece away.
