Description
Technical field
The invention belongs to turf machinery tool sharpening fields, are welded more specifically to a kind of robot for cutting careless hobboing cutter
Connection device cuts the welding method of careless hobboing cutter and the processing method for cutting careless hobboing cutter.
Background technology
With the improvement of living standards, the greening level requirement that people live to life is higher and higher, city large-scale ecological
Greenery patches, house greenery patches, Road Green Space etc. are continuously increased, therefore various machineries of mowing also constantly are released, wherein hob type
Grass trimmer (also referred to as grass-mowing machine, lawn machine) is liked because of the advantages that light-weight, small, operation is flexible be subject to user.
The principle of the realization cutting of grass trimmer is to be played grass volume by hobboing cutter, and the blade on hobboing cutter cuts off weeds.
The hobboing cutter of grass trimmer includes hobboing cutter axis, cutterhead and roll blade, and hobboing cutter assembling sequence is that multi-disc cutterhead interval first is threaded through rolling
It on cutter shaft, and is welded and fixed, then will be welded and fixed in the slot of roll blade insertion cutterhead, be finally ground blade, and roll blade
Twist.
Due to roll blade twist, it is more demanding to the relative rotation angle between the cutterhead on hobboing cutter axis, ensure rolling
Blade can be smoothly inserted into the slot of cutterhead, therefore the positioning accuracy request for blade on hobboing cutter axis is higher.Just because such as
This, a kind of welding tooling for cutting careless hobboing cutter of inventor's Previous designs, corresponding Patent No.：It is 201611023786.4 public
Opening day is：On 2 15th, 2017, the welding tooling
Including pedestal and several support plates, several support plates are vertical, are placed equidistant on the pedestal；It is several
The one side of the support plate is both provided with a cutterhead locating piece, and the cutterhead locating piece is corresponding with location hole；It is several described
Support plate at the top of be both provided with a main shaft orientation slot；Several main shaft orientation slots are semi-circular groove, and same
On one axis；Several cutterhead locating pieces project to same plane after into the center of circle of the semi-circular groove described
Conplane subpoint centered on point, and array arrange.
Quickly position of the cutterhead on main shaft and angle can be positioned by above-mentioned welding tooling, then by artificial
Cutterhead is welded on main shaft by welding, meanwhile, the program gives corresponding welding method.But it is not provided with rolling
How blade is welded to the method on cutterhead, as long as this is because cutterhead position on main shaft position positioning after, directly by hobboing cutter
In slot on piece insertion cutterhead, welding is manually carried out, is the traditional easy mode of comparison, having no innovation can say.So can,
Long-term actual welding operation shows that such mode is extremely inconvenient, not only inefficiency, but also welding quality is difficult to ensure that, often
It needs secondary or even repeatedly does over again, also occur the situation of scrapping once in a while, this is because hobboing cutter is integrally cylinder, each roll blade exists
It is uniformly distributed along the circumference on cutterhead, space is more narrow and small between adjacent roll blade, the welding in so small space of worker's hand torch
It is extremely not easy, the visual field is also seriously stopped, and is spiral shape plus roll blade, and welding gun need to also move towards constantly conversion weldering with weld seam
Angle is connect, welding difficulty bigger disconnected weldering, overlap, the unequal weld defect of weld seam often occurs, substantially reduces hobboing cutter product matter
Amount.
It also has other devices for being related to hobboing cutter processing in the prior art, but is welded for roll blade, for example,
Chinese Patent Application No. is：201610791977.9 publication date is：The patent document on January 4th, 2017, discloses one kind and cuts
The roll blade inserting apparatus of careless machine hobboing cutter, it includes stent, hobboing cutter shaft fixing device, crane and device of returning sword, on crane
Equipped with multiple clamping devices, clamping device from top to bottom around assembling station helical pattern be distributed and be formed centrally within receiving it is to be added
The processing space of work semi-finished product is equipped between each clamping device and crane and drives corresponding clamping device to spiral center axis
The grafting driving mechanism of horizontal traversal, vertical and straight movement, hobboing cutter axis fix dress to crane up and down under the driving of elevating mechanism
It puts to fix vertical hobboing cutter axis and hobboing cutter axis can be driven to rotate.The program can be automatically performed the assembling of roll blade and knife rest,
The degree of automation of roll blade installation is improved, but also needs to weld after roll blade installation, is not provided with corresponding welding side
Method.
In addition, current hobboing cutter is after assembly welding, be generally directly ground blade, hobboing cutter integrally unsightly, blade intolerant to
Mill, using easy rust after a period of time, it is necessary to reconditioning, and resistance to corrosion is weak, is long placed in and gets rusty easily.And roll blade
Blade is spiral shape, and postwelding grinding is also difficult point place, and there is presently no special equipment for grinding.
The content of the invention
1st, to solve the problems, such as
The present invention provides a kind of robotic welding apparatus for cutting careless hobboing cutter, and its object is to solve existing roll blade manually to weld
It connects, due to welding narrow space, the problem of welding efficiency is low caused by the visual field is obstructed, and weldquality is poor.The welding of the present invention
Device is to cut the matched auxiliaring equipment that careless hobboing cutter uses robot welding, welding robot can be coordinated to be rapidly completed roll blade and knife
Whole welding can be completed in welding between disk, clamped one time, and high degree of automation, welding efficiency is high, and weldquality is good.
The present invention also provides the welding method for cutting careless hobboing cutter, by assembled hobboing cutter clamped one time to welder,
And coordinate the welding of efficient, high quality the completion roll blade of welding robot.
The present invention also provides the processing method for cutting careless hobboing cutter, it can process wear-resisting and corrosion resistant cut careless hobboing cutter.
2nd, technical solution
