Description
Technical Field
The utility model relates to a cylindrical roller hydraulic pressure chucking device especially relates to a large-scale cylindrical roller hydraulic pressure chucking device.
Background
At present, the drilling process of large cylindrical rollers (such as RU80, 150-ELP1) adopts a numerical control lathe three-jaw chuck for clamping, a tailstock is provided with a twist drill, workers manually shake a lead screw for drilling and forming, the drilling cooling mode of the twist drill is a water pump external cooling mode, the drill is worn quickly during drilling, the working efficiency is low, the size of a drilled hole is unstable, the deviation ratio is large, the workers drill about 120 pieces per time, one piece is drilled in 4 minutes on average, the drilling time of the workers manually shake the lead screw is long, the workers are tired, the production efficiency is reduced, and the qualified rate of finished products is also reduced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem overcome prior art not enough, provide one kind and can use on vertical machining center workstation, accomplish the cylindrical roller hydraulic pressure chucking device that carries out drilling processing to large-scale cylindrical roller.
The technical scheme of the utility model be a cylindrical roller hydraulic pressure chucking device, the backing plate is fixed on the workstation, backing plate side and bent plate fixed connection, fixed mounting hydraulic cylinder on the bent plate, screw and positioning seat fixed connection are passed through to the backing plate upper surface, guide block and positioning seat fixed connection are equipped with the slider in the guide way of guide block, and hydraulic cylinder's ejector pin passes the guide block, pushes up on the slider. And a spring is arranged between the positioning seat and the sliding block. The positioning seat on be processed and to have left V type groove, left V type groove V-arrangement angle is 90. The slider on process have right V type groove, right V type groove V-arrangement angle is 90.
The hydraulic clamping device for the cylindrical roller is fixedly installed on a workbench of a machining center, the cylindrical roller is placed in a 90-degree left V-shaped groove and a 90-degree right V-shaped groove of the positioning seat, an ejector rod of a hydraulic oil cylinder pushes a sliding block in the guide groove to move, the sliding block and the positioning seat clamp the cylindrical roller, a main shaft drives a drill bit to rotate and move downwards, drilling and machining of the cylindrical roller are completed, the drill bit adopts a U drill, a front edge of the U drill is of a hard alloy material inner-cooling structure, the hard alloy material of the front edge of the U drill is wear-resistant, inner-cooling is smoothly arranged and machined, and drilling machining quality. After drilling is completed, the main shaft drives the drill bit to return to the working original point, the hydraulic oil cylinder retracts into the ejector rod, the sliding block loosens the cylindrical roller under the action of the spring force, and after the cylindrical roller is replaced, the machining is repeated according to the steps.
The beneficial effects of the utility model are that no longer need the manual lead screw of shaking of workman to carry out drilling processing, reduced workman's intensity of labour, improved product percent of pass and production efficiency.
