Abstract
The invention discloses a cross beam reset clamping device and relates to the technical field of mechanical equipment. The cross beam reset clamping device comprises a plurality of clamping control units mounted on a cross beam press plate and a clamping base plate mounted below the cross beam press plate, each clamping control unit comprises an oil cavity arranged in the cross beam press plate, a gland is pressed on each oil cavity, a screw penetratingly arranged at the bottom of each oil cavity is arranged in the oil cavity, a spring is sleeved outside one end, penetrating into the corresponding oil cavity, of each screw, and a clamping piston is connected with the other end, extending out of the corresponding oil cavity, of each screw. The clamping pistons are mounted in a piston slide of the cross beam press plate, and the clamping base plate closes an opening of the piston slide. The cross beam reset clamping device can solve the problems that the cross beam clamping state of a large-scale gantry machine tool is not stable enough, and working efficiency is low.
Description
Technical field
The present invention relates to plant equipment manufacturing technology field, especially a kind of clamping device for large-sized gantry machine crossbeam.
Background technology
To all adopting beam movable large-sized gantry machine in a lot of situations of the processing of large-scale workpiece, this class lathe is when machining large workpiece at present, and crossbeam not only needs normal movement on column, also needs to fix; In the time of fixedly, need to use clamping device to increase lathe rigidity, the degree of clamping and state are very large to the Accuracy of part, if clamping efficiency is not difficult to guarantee crudy in higher position.And in prior art, clamping device is to adopt dish spring-lever clamping device, it be while utilizing the oil cylinder work be arranged on crossbeam below to dish spring pressure, the compression of dish spring produces the one end that acts on lever after elastic force, at the lever other end, by clamp, crossbeam is clamped on the guide pass of column.Its shortcoming and defect is that clamped condition is firm not, and operating efficiency is not high, and simultaneously dish spring-lever clamps its sealing property is had relatively high expectations, easily leak, and this type of clamping device complex structure in addition, assembly work amount is large.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of crossbeam reset clamping device, and it is firm not that it can solve large-sized gantry machine crossbeam clamped condition, the problem that operating efficiency is lower.
In order to address the above problem, technical scheme of the present invention is: this crossbeam reset clamping device, include a plurality of clamping control modules that are arranged on crossbeam pressing plate and be arranged under crossbeam pressing plate and clamp backing plate, described clamping control module includes the oil pocket being located in described crossbeam pressing plate, on described oil pocket, be pressed with gland, in described oil pocket, be provided with the screw rod interting in its bottom, its overcoat of one end that described screw rod interts in described oil pocket has spring, and the other end that described screw rod stretches out outside described oil pocket is connected with clamping piston; Described clamping piston is arranged in the piston slideway of being located at described crossbeam pressing plate, and described clamping backing plate seals described piston slideway road junction.
In technique scheme, more specifically scheme can also be: described spring is disk spring, and cover has one end of the described screw rod of described spring to be connected with the nuts and washers that compresses described spring; The wing plate of described gland is fixed on described crossbeam pressing plate, between described wing plate and described crossbeam pressing plate, is provided with sealing ring.
Further: between described clamping piston and described piston slideway, to be provided with sealing ring and back-up ring.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, the present invention not only can effectively clamp crossbeam, and can loosen fast crossbeam, increases work efficiency.
2, the present invention increases the rigidity of lathe, and not only clamping force is large, and whole clamping device is simple in structure, safe and reliable.
accompanying drawing explanation
Fig. 1 is the embodiment of the present invention 1 structural representation.
Fig. 2 is the embodiment of the present invention 2 structural representations.
Fig. 3 is Z place enlarged drawing in Fig. 1.
Fig. 4 is hydraulic structure schematic diagram of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
Crossbeam reset clamping device shown in Fig. 1 and Fig. 3, includes 6 clamping control modules that are arranged on crossbeam pressing plate 2 and is arranged on 2 times clamping backing plates 1 of crossbeam pressing plate.These clamp control module and include the gland 5 that is placed in the oil pocket in crossbeam pressing plate 2, O RunddichtringO 6, packing ring 7, disk spring 8, screw rod 9, clamping piston 10, back-up ring 11 and O RunddichtringO 12; O RunddichtringO 12 is arranged on that on clamping piston 10, to be used for sealed high pressure oily, and back-up ring 11 is arranged on and on clamping piston 10, is used for protecting sealing ring 12; Screw rod 9 one end are threaded connection on clamping piston 10, the other end of screw rod 9 is connected with the nuts and washers 7 of holddown spring 8, spring 8 is disk spring, unclamps direction move by the certain precompression of the given disk spring 8 of nut with assurance clamping piston 10 to crossbeam; The wing plate 5-1 of gland 5 is screwed on crossbeam pressing plate 2, between wing plate 5-1 and crossbeam pressing plate 2, is provided with sealing ring 6, and sealing ring 6 is O RunddichtringO, is used for sealing spilling of a small amount of fluid.At crossbeam top, place a two-bit triplet solenoid directional control valve 14 and a pressure switch 13, as Fig. 4, this pressure switch is provided with upper and lower limit pressure, and front this solenoid directional control valve of cross beam movement obtains electric, the oil return of clamping oil cylinder.When system pressure sends by pressure switch 13 signal that crossbeam has unclamped during lower than 3MPa, crossbeam can move.When two-bit triplet solenoid directional control valve 14 dead electricity, hydraulic oil, promotes clamping piston 10 and compresses respectively clamping backing plate 1 clamping crossbeam to each clamping point through solenoid directional control valve 14.When hydraulic fluid tank charge oil pressure is greater than 15MPa, by pressure switch 13, send crossbeam and clamped signal, now crossbeam can not move.Fig. 2 is another embodiment of the present invention, and crossbeam pressing plate 3 is arranged on crossbeam by screw fastening, is separately installed with 4 and clamps control module on crossbeam pressing plate 3 two ends; Crossbeam pressing plate 3 is slightly different with embodiment 1 middle cross beam pressing plate 2 structures, and the effect of crossbeam wedge 4 is identical with the effect that compresses clamping backing plate 1 in embodiment 1, and other structure is identical with embodiment 1 with control principle.
