Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of structure simple, compact, easy to install and use, quality of fit is high, the wearing and tearing of cutter can be reduced, improve cutting-tool's used life, reduce the combination tool rest of the pavement milling machine of use cost.
The object of the invention is to have come by following technical solution, a kind of combination tool rest of pavement milling machine, it is formed primarily of the tool rest for laying cutter head with for the pedestal be fixed on by tool rest on milling machine, offer a triangle in the middle of described pedestal and connect slotted eye, inclined-plane, described pedestal top one offers triangle connects slotted eye, for the tool rest connector uncovered hypotenuse from top grafting, this uncovered hypotenuse is as the fitting face of tool rest and pedestal; Described tool rest is a class triangle, be plugged on by leading portion tool post obliquely and back segment the tool rest connector that triangle is connected in slotted eye to form, the leading section of tool post offers the cutter head installing hole for cutter grafting, and described tool rest connector is a triangle tenon block being connected that with triangle slotted eye matches.
The inner side edge edge of described triangle connection slotted eye offers the filler rod groove to both sides indent, and on the outer side edges edge of corresponding triangle tenon block, be provided with the filler rod block to both sides projection; Described triangle tenon block and tool post joint are formed with the step surface being matched with the uncovered hypotenuse in pedestal side; Described tool rest upper surface offers the oblique cutter head being communicated with cutter head installing hole and unload cutter groove.
The opposite side described pedestal being positioned at triangle connection slotted eye offers and tilts from the top down and fixing duct that triangle connects slotted eye, that be configured with set bolt of going directly, on the respective outer limit of triangle tenon block, be provided with tilting fixing slotted eye accordingly, and make fixing duct and described holddown groove hole form a complete bolt fixing hole road.
The invention belongs to and improve the one of prior art, it is simple, compact that it has structure, easy to install and use, and quality of fit is high, can reduce the wearing and tearing of cutter, improves cutting-tool's used life, reduces the features such as use cost.
Accompanying drawing explanation
Fig. 1 is integrally-built decomposition texture schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, the combination tool rest of a kind of pavement milling machine of the present invention, it is formed primarily of the tool rest 1 for laying cutter head with for the pedestal 2 be fixed on by tool rest on milling machine, offer a triangle in the middle of described pedestal 2 and connect slotted eye 3, inclined-plane, described pedestal 2 top one offers the uncovered hypotenuse 4 that triangle connects slotted eye 3, tool rest 1 as the fitting face of tool rest and pedestal, can be located on the base 2 from top grafting for tool rest connector 5 by this uncovered hypotenuse 4 easily; Described tool rest 1 is a class triangle, be plugged on by leading portion tool post 6 obliquely and back segment the tool rest connector 5 that triangle is connected in slotted eye to form, the leading section of tool post 6 offers the cutter head installing hole 7 for cutter grafting, described tool rest connector 5 is a triangle tenon block being connected that with triangle slotted eye matches, can be plugged on triangle easily connects in slotted eye, being fixedly connected with of both realizations.
Shown in figure, the inner side edge edge of described triangle connection slotted eye 3 offers the filler rod groove 8 to both sides indent, and the filler rod block 9 be provided with on the outer side edges edge of corresponding triangle tenon block to both sides projection, connect slotted eye when the triangle tenon block on tool rest is inserted triangle from uncovered hypotenuse, realize according to the mutual interlocking of filler rod block 9 along filler rod groove 8, they play positioning action, ensure installation quality of fit each other; Described triangle tenon block and tool post 6 joint are formed with the step surface 10 being matched with the uncovered hypotenuse in pedestal side; Described tool rest 1 upper surface offers the oblique cutter head being communicated with cutter head installing hole 7 and unload cutter groove 11.
Opposite side pedestal 1 of the present invention being positioned at triangle connection slotted eye 3 offers and tilts from the top down and fixing duct 13 that triangle connects slotted eye 3, that be configured with set bolt 12 of going directly, tilting fixing slotted eye 14 is provided with accordingly on the respective outer limit of triangle tenon block, and make fixing duct 13 form a complete bolt fixing hole road with described fixing slotted eye 14, injected in described fixing duct 13 and fixing slotted eye 14 by set bolt 12, tool rest 1 is securely fixed on pedestal 2.
The present invention is provided with circle drum locating hole 15 in the middle of the bottom surface of pedestal 2 and triangle described in being communicated with connects slotted eye 3 in addition; Described pedestal 2 bottom surface is the curved mounting surface 16 of one and circle drum fitting face.
