Description
Technical field
It is more particularly to a kind of to reduce the required folder for loosening oil pressure the present invention relates to a kind of clamping structure
Locking structure.
Background technology
Heavy duty metal stock-removing machine, particularly heavy vertical lathe and heavy-duty floor-type boring machine, to ensure
Processing rigidity, its moving component is required for being fixedly clamped in process.Traditional clamping structure is adopted
Single-acting cylinder structure is used, is occurred situations such as clamp and loosen by oil pressure, and once power off, oil pressure lets out
After leakage, clamping is ineffective, causes potential safety hazard.For problem above, the present invention intends to such folder
Locking oil cylinder structure is improved.
The content of the invention
The purpose of the present invention is directed to the deficiencies in the prior art, there is provided a kind of security performance is higher
, double acting cylinder structure improves security performance to reduce the pressure of whole oil hydraulic system.In dead electricity feelings
Remain to ensure the decompression clamping structure for clamping under condition.
Decompression clamping structure described in the present invention, mainly including clamping cylinder, studdle, clamping spiral shell
Bar, head clamp, movable compact heap, packing ring etc..Clamping cylinder is placed on crossbeam, clamping screw peace
Put in one end of head clamp, movable compact heap is placed in the other end of head clamp by bearing pin, support spiral shell
Bar is fixed on crossbeam, the hole being engaged with studdle is provided with head clamp, by head clamp
Hole be placed on studdle, packing ring and clamp nut are provided with head clamp.After head clamp is installed,
Movable compact heap is in contact with column, and clamping screw reaches outside cylinder body with clamping cylinder piston A
End in contact.Described packing ring can be spherical washer.
The operation principle of decompression clamping structure：After clamping cylinder logical oil, hydraulic oil band piston A contractings
Return, piston A departs from clamping screw, now, clamp system is in relaxation state；Work as clamping cylinder
After emptying, disk spring promotes piston B and band piston A stretches out, and piston A holds out against clamping screw,
The leverage formed by head clamp and packing ring is acted on movable compact heap thrust, by living
Thrust is converted into frictional force by dynamic compact heap, and be fixed on crossbeam on column by the gravity of equalizer.
Clamping cylinder includes cylinder body, piston, baffle plate, disk spring, locking device, sealing ring, oil
Pipe joint etc..Baffle plate, piston A, piston B are all positioned in the cylinder body of clamping cylinder, are set in cylinder body
Oil circuit is equipped with, baffle plate is fixed between cylinder body inner carrier A and piston B, piston A and piston B can
Slided with cylinder body.One end of piston A is reached outside cylinder body, and the other end of piston A passes through baffle plate
It is in contact with piston B, piston A forms oil pocket A with cylinder body, and UNICOM's oil pocket is provided with piston A
The passage of B；One end of piston B is mounted with disk spring, and piston B forms oil pocket B, lock with baffle plate
Tight device is arranged on one end of clamping cylinder.
The working condition and principle of clamping cylinder be：Disk spring is placed on piston B, locking nut
It is placed in cylinder body.Locking nut compresses disk spring after installing, and disk spring promotes piston B,
Piston B ejects piston A, and now, whole clamping structure is in clamped condition.When clamping cylinder is logical
After oil, oil pocket A and oil pocket B can fill hydraulic oil, and the hydraulic oil in oil pocket A promotes piston A contractings
Return, piston A band pistons B retracts, the hydraulic oil in oil pocket B also promotes piston B to retract simultaneously,
So, piston B bears the thrust of 2 times of hydraulic oil to promote disk spring to compress, therefore this hair
Bright used decompression pressure of hydraulic oil needed for clamping structure is that the half of single cylinder structure can be pushed away
Piston is retracted.
The present invention is improved clamping cylinder structure, using double acting cylinder structure, by disk spring
Power is clamped, and oil pressure is only loosened.Disc spring force is mechanical force, it is not necessary to which being powered can complete folder
Tightly, its working condition is not influenceed in special circumstances such as power-off.As a result of double acting cylinder, institute
Oil pressure is loosened with oil cylinder and only needs to execution by the half of traditional structure, reduce whole oil pressure
The pressure of system, improves security performance.
On an equipment, decompression clamping structure of the present invention both can be used alone, and also may be used
It is applied in combination with many sets.
Brief description of the drawings
Fig. 1 is the clamping structure schematic diagram described in the present invention；
Fig. 2 is clamping cylinder schematic diagram.
Specific embodiment
Below in conjunction with accompanying drawing to the decompression clamping structure described in the present invention, it is further described and explains.
Fig. 1 is the decompression clamping structure schematic diagram described in the present invention.As shown in figure 1, described decompression
Clamping structure, installed in the crossbeam back of Digit Control Machine Tool, including crossbeam 1, clamping cylinder 2, clamping spiral shell
It is bar 3, head clamp 4, studdle 5, nut 6, packing ring 7, bearing pin 8, movable compact heap 9, vertical
Post 10 etc..Clamping cylinder 2 is arranged on crossbeam 1.Clamping screw 3 is arranged on one end of head clamp 4,
Movable compact heap 9 is connected by bearing pin 8 with head clamp 4, and movable compact heap 9 can be small around bearing pin 8
The rotation of scope.Studdle 5 is arranged on crossbeam 1, and head clamp 4 is added after assembling by advance
