Abstract
The utility model relates to a kind of elastic deformation formula brake apparatus of building-block machine rotary table, the hydraulic jack comprising rotating shaft (2), hold-down support (1), braking flange (4) and be made up of oil cylinder seat (5), oil cylinder piston (8) and gland (7), the flange end of braking flange (4) is sandwiched between the end face of oil cylinder piston (8) and oil cylinder seat (5), and minim gap is all left, oil pocket (13) the external hydraulic oil pump of hydraulic jack in the both sides of braking flange (4) flange end.Its structure is simple, and rapidly, highly sensitive, braking moment is large in braking.When passing into pressure oil, and keep pressure, braking flange is pressed on holder by flange-type oil cylinder piston, utilizes this rotating shaft of frictional force brakes between them.When after release oil cylinder working-pressure, the elastic deformation of braking flange is recovered, the brake release of turntable shaft.
Description
Technical field
The utility model relates to a kind of annex of building-block machine, particularly a kind of elastic deformation formula brake apparatus of building-block machine rotary table.
Background technology
Rotary table is one of critical piece of building-block machine.Current rotary table is the type of drive adopting turbine and worm mostly, and because turbine and worm has auto-lock function, therefore its rotary table does not need arrestment mechanism.And the turntable adopting torque motor directly to drive, when receiving halt instruction, braking motor is carried out by dynamic brake circuit, its self-lock force is less, can be there is very low-angle mistake and turn in the especially anxious stopping time, in rotary table, thus need a set of arrestment mechanism to clamp turntable to ensure accurate positioning requirements.In addition under gravity chip, also need braking turntable shaft to ensure the machining accuracy of common workpiece.
Summary of the invention
Technical barrier to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of elastic deformation formula brake apparatus of building-block machine rotary table, accurately locate to enable workbench.
Technical solution of the present utility model is, comprise rotating shaft (2) and hold-down support (1), it is characterized in that: the axle head of rotating shaft (2) is connected with braking flange (4), the outside of braking flange (4) is provided with the hydraulic jack be made up of oil cylinder seat (5), oil cylinder piston (8) and gland (7), oil pocket (13) the external hydraulic oil pump of its hydraulic jack; The flange end of braking flange (4) is sandwiched between the end face of oil cylinder piston (8) and oil cylinder seat (5), and minim gap is all left in the both sides of braking flange (4) flange end.
Between braking flange (4) and rotating shaft (2), between oil cylinder piston (8) and gland (7), between gland (7) and oil cylinder seat (5), between oil cylinder seat (5) and hold-down support (1), be fixedly connected with respectively by screw (3,9,6,12).
Described oil pocket (13) is positioned between gland (7) and oil cylinder piston (8).
The utility model and prior art compare, and the advantage possessed is, the external hydraulic pump of oil pocket of oil cylinder, utilizes the elastic deformation of flange own material, carry out compression braking.Its structure is simple, and rapidly, highly sensitive, braking moment is large in braking.

Detailed description of the invention
The utility model comprises rotating shaft (2), hold-down support (1), braking flange (4), oil cylinder seat (5), oil cylinder piston (8) and gland (7),
The axle head of rotating shaft (2) is connected with braking flange (4) by screw (3), the outside of braking flange (4) is provided with the hydraulic jack be made up of oil cylinder seat (5), oil cylinder piston (8) and gland (7), oil pocket (13) the external hydraulic oil pump of its hydraulic jack.Described oil pocket (13) is positioned between gland (7) and oil cylinder piston (8).
The flange end of braking flange (4) is sandwiched between the end face of oil cylinder piston (8) and oil cylinder seat (5), and minim gap is all left in the both sides of braking flange (4) flange end.
Between braking flange (4) and rotating shaft (2), between oil cylinder piston (8) and gland (7), between gland (7) and oil cylinder seat (5), between oil cylinder seat (5) and hold-down support (1), be fixedly connected with respectively by screw (3,9,6,12).
Rotating shaft (2) is connected with the table top of rotary table.Junction adopts seal (10) and seal (11) to seal.
The utility model is a kind of arrestment mechanism be applied on apparatus for rotating, by the external hydraulic pump of the oil pocket of oil cylinder, utilizes the elastic deformation of oil cylinder piston and braking flange own material, brakes rotating shaft (2).When passing into the medium of certain pressure in oil pocket (13), this pressure acts on oil cylinder piston (8), the flange material of oil cylinder piston (8) itself is made to produce small elastic deformation, then compressing braking flange (4) produces elastic deformation and is pressed on oil cylinder seat (5), oil cylinder piston (8) and braking flange (4) both distortion all belong in the regime of elastic deformation of material, the flange both sides of finally braking flange (4) are pressed between oil cylinder piston (8) and oil cylinder seat (5), thus generation braking moment, reach the rotation of brake rotation shaft (2).When in oil pocket (13), cancellation passes into pressure medium, due to properties of materials, braking flange (4) and the distortion of oil cylinder piston (8) recover again original state, and braking flange (4) again can normal rotation, braking effect disappears, rotating shaft (2) normal rotation.
Claims (3)
1. the elastic deformation formula brake apparatus of a building-block machine rotary table, comprise rotating shaft (2) and hold-down support (1), it is characterized in that: the axle head of rotating shaft (2) is connected with braking flange (4), the outside of braking flange (4) is provided with the hydraulic jack be made up of oil cylinder seat (5), oil cylinder piston (8) and gland (7), oil pocket (13) the external hydraulic oil pump of its hydraulic jack; The flange end of braking flange (4) is sandwiched between the end face of oil cylinder piston (8) and oil cylinder seat (5), and minim gap is all left in the both sides of braking flange (4) flange end.
