background technology
The application holds patent CN101816967B formerly, title " cone sand making machine and sand method processed ", bevel gear wheel is enclosed within on excentric sleeve, excentric sleeve is enclosed within by copper overcoat in the axis hole at lower casing center, main shaft is positioned at excentric sleeve and is promoted spindle swing by excentric sleeve by interior copper sheathing, spheric seating is arranged on the housings support circle of positioning shaft hole of lower casing, mantle is enclosed within on main shaft and is promoted mantle by main shaft by sphere brasses and swings, movable sleeve bushing is enclosed within on the conical surface of mantle, anti-wear movable sleeve is enclosed within on the conical surface of movable sleeve bushing, the tight device of embedding is enclosed within on main shaft and adopts locking nut that tight embedding device is locked, upper casing coordinate with lower casing and upper casing flanging and lower casing flanging between be provided with the above adjustment oil cylinders of three or three, upper casing inwall sawtooth helical form and being meshed with the toroidal helical sawtooth of adjusting swivel nut outer wall ringwise, adjust swivel nut and be double horn shape structure, its lower loudspeaker wall is connected with anti-wear fixed sleeve by fixed sleeve bushing, upper loudspeaker wall is used for supporting hopper assembly.Its place requiring further improvement is: the one, and because touching face mutually, main shaft and interior copper sheathing (main shaft copper sheathing) be oil film face dynamic support, and roll process in gravity all the time with the stress surface (half of main shaft copper sheathing inwall) of main shaft copper sheathing in the process that main shaft gyration rotates, cause main shaft, main shaft copper sheathing all the time in the condition of high temperature, cause oil film to lose efficacy; The 2nd, because main shaft copper sheathing is made up of copper, tin, lead, when main shaft, main shaft copper sheathing, excentric sleeve are during in the condition of high temperature, tin (or tin and lead) fusing that forms main shaft copper sheathing is overflowed from main shaft copper sheathing wall, eccentric shaft jacket wall, cause main shaft copper sheathing, excentric sleeve to become alveolate texture, intensity is lost to the greatest extent, main shaft copper sheathing and excentric sleeve fracture, fragmentation, cause sand machine processed to work.
Summary of the invention
Purpose of design: avoid the weak point in background technology, design a kind of from according to solving in excentric sleeve and overheated the caused excentric sleeve of main shaft copper sheathing circular cone sand making machine, main shaft copper sheathing material because institute is stanniferous, lead overflows, the main shaft copper sheathing causing, the circular cone sand making machine excentric sleeve cooling structure with water cooling function that excentric sleeve fracture phenomena occurs.
Design: in order to realize above-mentioned purpose of design.1, the periphery of excentric sleeve has spindle mounted shaft hole inner wall in multi-ring annular groove and excentric sleeve periphery and circular cone sand making machine lower casing and matches and form the design in multi-turn water cooling chamber, is one of technical characterictic of the present utility model.The object of doing is like this: form multi-turn water cooling chamber because the periphery of excentric sleeve and spindle mounted shaft hole inner wall match, on this multi-turn water cooling chamber corresponding spindle mounted axis hole wall, have inlet opening and apopore and inlet opening and apopore and be respectively vertical arrangement, the inlet opening that this is vertically arranged and apopore adopt respectively vertical groove to be communicated with, its water inlet groove is communicated with water-cooling circulating device delivery port by water inlet pipe and connecting leg, water outlet groove is communicated with water-cooling circulating device water inlet by outlet pipe and connecting leg, under water-cooling circulating device effect, cooled water injects water inlet groove by the water inlet pipe of the groove of intaking, injected in multi-turn water cooling chamber by the inlet opening on spindle mounted axis hole wall by water inlet groove again, not only realize completely cooling to excentric sleeve, and by excentric sleeve, water-cooled energy is passed to main shaft copper sheathing and carries out continuously cooling to main shaft copper sheathing, cooling main shaft copper sheathing carries out cooling to main shaft again, thereby reach excentric sleeve, the object that main shaft copper sheathing and main shaft are cooling, the more important thing is and fundamentally solved formation excentric sleeve, the excentric sleeve that the material of main shaft copper sheathing causes due to high temperature, tin or tin and plumbous and overflow formed excentric sleeve in main shaft copper sheathing material, main shaft copper sheathing is the generation of alveolate texture, avoid the excentric sleeve that caused thus, main shaft copper sheathing intensity is lost to the greatest extent, the generation of phenomenon of rupture.2, the design of water-cooling circulating device is two of technical characterictic of the present utility model.The object of doing is like this: because water-cooling circulating device had both had water filling device with pressure, there is again water cooling system, it can either force cooled water to inject in multi-turn water cooling chamber, can continuously conduct cooling to copper sheathing, main shaft inside and outside main shaft by excentric sleeve again, thereby respectively with make to reach the operating temperature that reduces copper sheathing and main shaft inside and outside main shaft, guarantee that the temperature rise of the inside and outside copper sheathing of main shaft can not exceed the molten point of its tin, avoids the generation of the inside and outside copper sheathing honeycomb of main shaft.
Technical scheme: a kind of circular cone sand making machine excentric sleeve cooling structure with water cooling function, comprise circular cone sand making machine lower casing, in described circular cone sand making machine, the periphery of excentric sleeve has in multi-ring annular groove and excentric sleeve periphery and circular cone sand making machine lower casing spindle mounted shaft hole inner wall and matches and form multi-turn water cooling chamber, multi-turn water cooling chamber is interconnected and multi-turn water cooling chamber upper water cooling chamber is communicated with the water inlet pipe being arranged on lower casing, and water cooling chamber, bottom, multi-turn water cooling chamber is communicated with outlet pipe.
The utility model is compared with background technology, excentric sleeve periphery has multi-ring annular groove, excentric sleeve periphery and spindle mounted shaft hole inner wall match and form multi-turn water cooling chamber, both realized excentric sleeve directly cold, realize again the excentric sleeve after water-cooled to main shaft copper sheathing, the conduction of main shaft is cooling, not only reduce the operating temperature of main shaft copper sheathing and main shaft, and guarantee to form excentric sleeve, in main shaft copper sheathing material, the temperature rise of tin can not exceed the molten point of tin, avoid excentric sleeve, the generation of main shaft copper sheathing honeycomb, and then avoid excentric sleeve, the fracture of main shaft copper sheathing, broken, guarantee the normal work of circular cone sand making machine.
