Description
Technical field
The utility model belongs to Machining Technology field, particularly relates to a kind of grinding center based on Crankshaft Machining.
Background technology
Bent axle is the main rotary gadget of engine, and after loading onto connecting rod, upper and lower (back and forth) motion can accepting connecting rod becomes circulation (rotation) motion.Be the important parts of on engine one, its material is made up of carbon structural steels or spheroidal graphite cast-iron, has two significant points: trunnion, connecting rod neck.Trunnion is installed on cylinder body, and connecting rod neck is connected with crank pin end pore, and connecting rod small end hole is connected with steam-cylinder piston, is a typical slider-crank mechanism.The lubrication of bent axle mainly refers to and big end bearing shell and the lubrication of crank-shaft link neck and the lubrication of two fixing point.The rotation of bent axle is the power source of engine, is also the driving source of whole mechanical system.The crankshaft grinding center of current practical application, when bearing block positions bent axle under the effect of oil cylinder, because the active force of oil cylinder is comparatively large, easily cause damage to bent axle, and oil cylinder movement error is comparatively large, operation inconvenience.
Summary of the invention
The utility model provides a kind of grinding center based on Crankshaft Machining, to solve the larger problem of the cylinder force that proposes in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of grinding center based on Crankshaft Machining, it is characterized in that: comprise base, cavity is provided with in described base, leading screw is provided with in described cavity, described leading screw is provided with clutch shaft bearing seat, second bearing block, limited block, described limited block is positioned at clutch shaft bearing seat, between second bearing block, described clutch shaft bearing seat, bent axle is provided with between second bearing block, described clutch shaft bearing seat side is provided with the first groove, described second bearing block side is provided with the second groove, one end of described bent axle is positioned at the first groove, the other end is positioned at the second groove, the first protective sleeve is provided with between described bent axle and clutch shaft bearing seat, the second protective sleeve is provided with between described bent axle and the second bearing block, described clutch shaft bearing seat opposite side is provided with the first joint pin, described first joint pin is provided with the first oil cylinder, described second bearing block opposite side is provided with the second joint pin, described second joint pin is provided with the second oil cylinder, described base upper surface is provided with the first support column, second support column, described first support column, second support column top is connected with crossbeam, mobile cylinder is provided with above described crossbeam, lower air cylinder, described mobile cylinder, connected by carriage release lever between lower air cylinder, the bottom of described lower air cylinder is connected with down-pressed pole, described crossbeam is provided with groove, described down-pressed pole is through groove and bottom is connected with cutterhead.
Described first support column, the second support column are isometric.
Described first oil cylinder, the second oil cylinder are symmetrical arranged.
The beneficial effects of the utility model are:
The technical program is by replacing original slide bar with leading screw; because leading screw surface is threaded; the frictional force between bearing block and leading screw can be increased; and leading screw is with scale; also the degree of accuracy of cylinder movement can be strengthened; the setting of protective sleeve in addition; can protect bent axle, prevent from being damaged in the process of processing, the setting of limited block; can carry out spacing to the bearing block of both sides; avoid due to maloperation, bearing block is piled up, damage equipment; lower air cylinder can move under the effect of movement, strengthens applicability.
