Plane（Structure shown in Figure 15）With the right angle step hole for having concentric circular requirement（Structure shown in Figure 16）Processing,
Because of the requirement of itself design, become the difficult problem for perplexing such turbine shroud part processing all the time.At present, such turbine
Housing part processing is processed using the anti-scraper of self-action mainly by machining center special fixture, the anti-scraper of self-action
Structure is more complicated, can not use on plain-milling machine, and processing cost is higher.Chinese Patent Application No. is 201220725427.4 reality
A kind of anti-scraper, including cutter head, bushing and knife bar are disclosed with new, one end clamping of the cutter head and knife bar, bushing are located at
Near one end of cutter head on knife bar.Knife bar is arranged on electric hand drill, transmission case zero is processed by way of manual operation
Part centre bore, above-mentioned anti-scraper are not appropriate for above-mentioned class turbine shroud flange reverse side spot face and the platform for having concentric circular requirement
The processing in rank hole.When anti-scraper is used, generally require and the knife bar of anti-scraper is passed through into corresponding hole in parts to be processed, then in knife
Cutter head is installed on the traversing through end of bar, be it requires cutter head clamping and dismantled fast and accurate positioning.
The content of the invention
It is an object of the invention to propose a kind of simple structure, facilitate cutter head clamping and dismounting and accurate positioning it is reverse
Scraper.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：The present invention has knife bar, cutter head and blade, described
The cylinder of knife bar is provided with the L-shaped tightening groove that the arc groove opened up by the straight trough opened up along bus and circumferentially line is constituted, tightening
The section of groove is right angled triangle, and the cutter head has centre bore, and the end face of cutter head is provided with
Embedding groove, the blade is inlaid with embedding groove, cutter head is enclosed within the head end of knife bar by centre bore, and cutter head is provided with screw thread
Hole, the holding screw that an afterbody is matched with tightening groove shape are screwed in the screwed hole of cutter head, the afterbody insertion knife bar of holding screw
On tightening groove in.
The centrage of four embedding grooves deviates the centrage in cutter head center hole, the side of all embedding groove the same sides and cutter head
Corresponding centerline on centre bore overlaps, and the blade side of blade is in embedding groove is overlapped with the centrage in cutter head center hole one
Side.
There is the opening of straight trough on the end face of knife bar.
The blade is rectangular-shaped blade.
The blade is arc-shaped blade.
The present invention has following good effect：This back scraper, is positioned with holding screw using tool bit casing on knife bar, side
Just the clamping of cutter head and dismounting.Knife bar is provided with L-shaped tightening groove, arc groove of the holding screw against L-shaped tightening groove, holding screw
Afterbody match with the tightening groove of right-angle cross-section, be similarly right angle, after tightening holding screw, will not occur between cutter head and knife bar
Displacement, can bear larger power, and accurate positioning.The part of this back scraper is few, and simple structure is easy to process, highly versatile,
Cost of manufacture is relatively low and favorably improves working (machining) efficiency, it is ensured that crudy.

Specific embodiment
Embodiment 1
See Fig. 1 to Figure 11, the back scraper of embodiment 1 has knife bar 1, cutter head 2 and blade 3, and the cylinder of the knife bar 1 is provided with
The L-shaped tightening groove 1-1, straight trough 1-1- being made up of the straight trough 1-1-1 opened up along bus and arc groove 1-1-2 that circumferentially line is opened up
1 and arc groove 1-1-2 is insertion.There is the opening of straight trough 1-1-1 on the end face of knife bar 1, the section of tightening groove 1-1 is right angle
Triangle.The cutter head 2 has centre bore 2-1, and the end face of cutter head 2 is provided with the embedding groove 2- that four radial directions are angularly distributed with
