Description
Technical field
The utility model belongs to turf machinery tool sharpening field, more specifically to a kind of machine for cutting careless hobboing cutter
People's welder and its welding method.
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 mowings machinery is also constantly 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 by 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 is first threaded through rolling
It on cutter shaft, and is welded and fixed, then roll blade is inserted into the slot of cutterhead and is welded and fixed, blade, and roll blade are finally ground
Twist.
Twist due to roll blade, the relative rotation angle between the cutterhead on hobboing cutter axis is more demanding, ensures rolling
Blade can be smoothly inserted into the slot of cutterhead, therefore higher for positioning accuracy request of the blade on hobboing cutter axis.Just because such as
This, a kind of welding tooling that cutting careless hobboing cutter of inventor's Previous designs, corresponding Patent No.：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 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 at the center of circle with the semi-circular groove described
Conplane subpoint centered on point, and array arrange.
It can quickly the position by cutterhead on main shaft and angle 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
Piece is inserted into the slot on cutterhead, artificial to carry out welding, 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, often
It needs secondary, or even repeatedly does over again, also occur scrapping situation 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 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 transformation weldering with weld seam
Angle is connect, welding difficulty bigger break weldering, overlap, the unequal weld defect of weld seam often occurs, substantially reduces hobboing cutter product matter
Amount.
Also have in the prior art it is other be related to hobboing cutter processing devices, but be seldom 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 holder, 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 sets for fixing vertical hobboing cutter axis and hobboing cutter shaft rotation can be driven dynamic.The program can be automatically performed the assembly 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 is easy rust, needs reconditioning, and resistance to corrosion is weak, be long placed in and get rusty easily after a period of use.And roll blade
Blade is spiral shape, and postwelding grinding is also difficult point place, and there is presently no special equipment for grinding.
