Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
A kind of turntable brake structure as shown in Figs 1-4,20, two cylinder bodies 10 of braking vane and piston 30, braking vane 20
It is mountable on the rotary axis system of turntable.One of end face of specific cylinder body 10 is formed as brake lining, above-mentioned braking vane 20
Between the brake lining of two cylinder bodies 10.It is equipped with 30 slot of inlet channel 11 and piston in cylinder body 10, makes 30 slot of piston
One end is connected to inlet channel 11, and the other end of 30 slot of piston runs through brake lining.In inlet channel 11 when air inlet, piston 30
It can be moved towards close brake lining and stretch out in brake lining to be connected on braking vane 20.In addition, in 30 slot of piston and piston 30
Between be clamped with elastomeric element 60, which answers for providing the elasticity for moving piston 30 away from brake lining
Power.
It, can be logical in the air inlet of cylinder body 10 when on the basis of the said structure, using the turntable brake structure of the utility model
Ventilation in road 11, piston 30 can be moved towards the brake lining of cylinder body 10 after air inlet, and be connected to and connect with the rotary axis system of turntable
Braking vane 20 on, and there are two above-mentioned cylinder body 10 sets, braking vane 20 is located between the brake lining of two cylinder bodies 10, i.e., into
When row brake, braking vane 20 can abut simultaneously clamping by the piston 30 on two cylinder bodies 10, brake be completed, using Bidirectional clamping side
Formula, shaft will not influence shafting precision without additional forces.And service brake piece knot is replaced with the biggish braking vane 20 of thickness
Structure is avoided because of torsional deflection circumferential caused by the strength problem of brake block itself after brake, while being braked at work
Plate 20 will not generate axial deformation.And air inlet can be stopped after completing brake, piston 30 can answer under the action of elastomeric element 60
Position is automatically reset so that piston 30 and braking vane 20 be allowed to be detached from and unclamp the pivoting part of turntable by elastomeric element 60, is used
It is convenient.
Further, in this embodiment piston 30 can be equipped with it is multiple, it is corresponding in cylinder body 10 be equipped with multiple pistons 30
Slot makes multiple pistons 30 and 30 slot of multiple pistons around the central axis circumferentially-spaced of cylinder body 10, by multiple pistons 30
One-to-one correspondence is installed in 30 slot of piston, in this way, the air pressure in inlet channel 11 can push away simultaneously in inlet channel 11 when air inlet
It moves multiple pistons 30 and is pressed in braking vane 20 and exist, be upwardly formed counterpressure in the week of braking vane 20, make multiple pistons 30 and brake
Preferable fitting rate is kept in 20 circumferential direction of plate, brake process is more stable, and avoids the circumferential deformation of braking vane 20.
Further, also sealed groove can be offered far from the end face of brake lining in cylinder body 10, the sealed groove and piston
The perforation of 30 slots, is packaged with sealing cover 50 in sealed groove, and above-mentioned inlet channel 11, which can be spaced, to be formed in sealing cover 50 and lean on
Between 30 slot of end face and piston of 30 slot of nearly piston, in this way, the cylinder assembly assembly and maintenance that are formed are more convenient.When
So, in the case where no sealing cover 50, above-mentioned inlet channel 11, which can also be, directly to be processed in cylinder.
Further, it is clamped with the first sealing ring 70 between the outer wall of sealing cover 50 and the inner wall of sealed groove, makes to seal
Good sealing can be formed between lid 50 and sealed groove, prevent gas leakage.
More particularly, for the ease of air inlet, air inlet 12, one end perforation of the air inlet 12 can be equipped on cylinder body 10
To 10 end face of cylinder body, the other end of air inlet 12 is connected to the inlet channel 11, can import gas extremely by air inlet 12
In inlet channel 11, facilitate operation.Certainly, in the case where no air inlet 12, it can make external feeder directly and air inlet
Channel 11 is connected.
Further, end of above-mentioned 30 slot of piston far from brake lining can be equipped with limited step, in piston 30 far from brake
The end in face is equipped with limiting section 31, and when piston 30 is towards close to brake lining movement, limiting section 31 can be connected on limited step,
Prevent piston 30 from completely disengaging with 30 slot of piston.Certainly, in this structure basis, above-mentioned elastomeric element 60 is held on limiting section
Between 31 and limited step, i.e., when limiting section 31 is connected on limited step, elastomeric element 60 be can be compressed, and gas source is closed
Afterwards, elastomeric element 60, which can reset, pushes limiting section 31 to separate with limited step, and band piston 30 is moved away from brake lining, pine
Open braking vane 20.
In addition, waveform spring can be selected in the elastomeric element 60 in the present embodiment.
Further, it can be clamped with the second sealing ring 80 between the inner wall of 30 slot of outer wall and piston of piston 30, it can be more
Good raising air-tightness.
Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
