Abstract
The invention relates to a brake device of a combined machine tool rotating working table. The brake device comprises a rotating shaft (2), a fixed support (1), a brake flange (4) and a hydraulic oil cylinder, wherein the hydraulic oil cylinder is composed of an oil cylinder seat (5), an oil cylinder piston (8) and a gland (7). The flange end of the brake flange (4) is clamped between the end faces of the oil cylinder piston (8) and the oil cylinder seat (5). Tiny gaps are reserved in the two sides of the flange end of the brake flange (4) respectively. An oil cavity (13) of the hydraulic oil cylinder is connected with an external hydraulic oil pump. The brake device is simple in structure, rapid in braking, high in sensitivity and large in brake torque. When pressure oil is injected in and pressure is kept, the brake flange is pressed to the fixed support through the flange type oil cylinder piston, and the rotating shaft is braked through the friction force between the brake flange and the fixed support. After oil cylinder pressure is released, the elastic deformation of the brake flange can recover, and the braking of the rotating shaft is relieved.
Description
Technical field
The present invention relates to a kind of adnexa of building-block machine, particularly a kind of elastic deformation formula of building-block machine rotary table
Brake unit.
Background technology
Rotary table is one of critical piece of building-block machine.Rotary table is using turbine and worm mostly at present
Type of drive, because turbine and worm has auto-lock function, therefore its rotary table does not need arrestment mechanism.And adopt moment electricity
The turntable of machine direct drive, when being connected to halt instruction, carrys out braking motor by dynamic brake circuit, its self-lock force is less, especially
During jerk, to occur very low-angle mistake to turn, thus need in rotary table a set of arrestment mechanism to clamp turntable with
Ensure accurate positioning requirements.In addition it is also desirable to braking turntable axle to ensure the machining accuracy of common workpiece under gravity chip.
Content of the invention
Technical barrier to be solved by this invention is to overcome the deficiencies in the prior art, provides a kind of building-block machine revolution work
The elastic deformation formula brake unit of station, so that workbench can be accurately positioned.
The technical solution of the present invention is, including rotary shaft (2) and hold-down support (1) it is characterised in that: rotary shaft
(2) axle head is connected with braking flange (4), and the outside of braking flange (4) is provided with by oil cylinder seat (5), oil cylinder piston (8) and gland
(7) hydraulic jack constituting, the external hydraulic oil pump of oil pocket (13) of its hydraulic jack；The flange end of braking flange (4) is sandwiched in oil
Between the end face of 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 rotary shaft (2), between oil cylinder piston (8) and gland (7), gland (7) and oil cylinder seat
(5) between, between oil cylinder seat (5) and hold-down support (1), it is fixedly connected by screw (3,9,6,12) respectively.
Described oil pocket (13) is located between gland (7) and oil cylinder piston (8).
The present invention is compared with prior art, and the advantage possessing is, the external hydraulic pump of oil pocket of oil cylinder, using flange from
The elastic deformation of stature material, carries out compression braking.Its structure is simple, and braking is rapid, and sensitivity is high, and braking moment is big.

Specific embodiment
The present invention includes rotary shaft (2), hold-down support (1), braking flange (4), oil cylinder seat (5), oil cylinder piston (8) and pressure
Lid (7),
The axle head of rotary shaft (2) is passed through screw (3) and is connected with braking flange (4), and the outside of braking flange (4) is provided with by oil
The hydraulic jack that cylinder seat (5), oil cylinder piston (8) and gland (7) are constituted, the external hydraulic oil pump of oil pocket (13) of its hydraulic jack.
Described oil pocket (13) is located between gland (7) and oil cylinder piston (8).
The flange end of braking flange (4) is sandwiched between oil cylinder piston (8) and the end face of oil cylinder seat (5), and brakes flange (4)
Minim gap is all left in the both sides of flange end.
Between braking flange (4) and rotary shaft (2), between oil cylinder piston (8) and gland (7), gland (7) and oil cylinder seat
(5) between, between oil cylinder seat (5) and hold-down support (1), it is fixedly connected by screw (3,9,6,12) respectively.
Rotary shaft (2) is connected with the table top of rotary table.Junction adopts sealing member (10) and sealing member (11) to enter
Row sealing.
The present invention is a kind of arrestment mechanism being applied on apparatus for rotating, by the external hydraulic pump of the oil pocket of oil cylinder, utilizes
Oil cylinder piston and the elastic deformation of braking flange own material, rotary shaft (2) is braked.When being passed through one in oil pocket (13)
During the medium of constant-pressure, this pressure acts on oil cylinder piston (8) above so that the flange material generation of oil cylinder piston (8) itself is micro-
Little elastic deformation, then compressing braking flange (4) produces elastic deformation being pressed on oil cylinder seat (5), oil cylinder piston (8) and system
Both deformation of dynamic flange (4) broadly fall in the regime of elastic deformation of material, and finally the flange both sides of braking flange (4) are compacted
Between oil cylinder piston (8) and oil cylinder seat (5), thus producing braking moment, reach the rotation of brake rotation shaft (2).Work as oil pocket
(13) when cancellation is passed through pressure medium in, due to properties of materials, brake flange (4) and the deformation of oil cylinder piston (8) recovers again
State originally, braking flange (4) again can be with normal rotation, and braking effect disappears, rotary shaft (2) normal rotation.
