Description

A kind of hydraumatic chucking device

Technical field

The utility model belongs to field of machining, relates in particular to a kind of hydraumatic chucking device.

Background technology

The chucking of tailstock mainly is a pressing plate bolt and nut artificial mechanism chucking on lathe at present, and automaticity is low, and labor strength is big, and can't measure clamping force.When the lathe carrying was big, required clamping force was bigger, operation inconvenience.

The utility model content

The purpose of this utility model provides a kind of safe and reliable, and is easy to operate, can alleviate a kind of hydraumatic chucking device of labor strength.

The utility model comprises pressing plate, tailstock body, bed ways, plate, piston, oil cylinder and disk spring, is characterized in: pressing plate is housed below the tailstock body, fixes with it with screw, be provided with the plate that contacts with bed ways above the pressing plate.Oil cylinder is housed on the pressing plate, piston is housed in the oil cylinder, sealing ring is housed on the piston successively, disk spring is housed below the piston, oil cylinder lower end inner chamber is screwed with the plug screw of band screw, is screwed with double-screw bolt in its screw.Plate is provided with two opening dowel holes, and pin is housed in the hole, and plate and pressing plate are fixed, and plate can move up and down along two pins.

The utility model has the advantages that: simple to operate, clamping force is big, and is safe and reliable, can alleviate working strength of workers, enhances productivity.Not only can be used for tailstock tool longitudinal register chucking and loosen, also can be used for the chucking of other mechanical devices and loosen.

The specific embodiment

In Fig. 1,2,3: pressing plate 2 is housed below the tailstock body 3, fixedlys connected with tailstock body 3 with screw 1.Be provided with the plate 5 that contacts with bed ways 4 above the pressing plate 2, plate 5 is provided with two opening dowel holes, and pin 13 is housed in the hole, is fixed on the pressing plate 2 with pin 13 during assembling, and palette 5 can move up and down along two pins 13.The material of plate 5 adopts 60Si2MnA.Oil cylinder 9 is housed on pressing plate 2, in order to make oil cylinder not bear bigger pressure, adopted serial oil cylinders, piston 7 is housed in each oil cylinder, lip-

type packing

6,8 is housed on the piston 7 successively, 6 disk springs 10 are equipped with in piston 7 lower ends, oil cylinder 9 lower end inner chambers are screwed with the plug screw 11 of band screw, be screwed with double-screw bolt 12 in the screw, its effect is an initial position of adjusting piston 7 and disk spring 10, and whole cylinder seals with sealing ring.When hydraulic oil enters oil-in 15 from pipe joint 14, during to oil cylinder 9, piston 7 moves down 10 distortion of compressing butterfly spring, makes the gap about formation 0.3mm between plate 5 and the bed ways 4, realizes loosening.When in the oil cylinder 9 during not oil-feed, disk spring 10 recovers distortion, promoting piston 7 moves up, tailstock is clamped, at this moment the tensile force of disk spring 10 acts on 4 of plate 5 and the bed ways equably, produces very big frictional force simultaneously, makes the location, position of tailstock tool at needs, under the maximum carrying situation of lathe, length travel can not take place yet.

Shown in Fig. 5 and Fig. 6: Pressure gauge 20 in parallel in tailstock body 3 hydraulic circuits, its effect is to show operating pressure at any time, decide according to the concrete structure of equipment its position.When the electromagnetic actuation of the electromagnet of solenoid directional control valve YVI21 and pressure switch SPI 22, hydraulic oil in the fuel tank 16 arrives check valve 19,23, solenoid directional control valve YVI 21, pressure switch SPI 22 through oil pump 17, at this moment hydraulic oil is from oil-in 15 oiling in oil cylinder 9, piston 7 moves down, 10 distortion of compressing disk spring, it is removable that tailstock tool is loosened.When the electromagnet of the electromagnet of reversal valve YVI 21 and pressure switch SPI 22 disconnects, hydraulic oil is intercepted by check valve 23,19, flow back to fuel tank 16 through overflow valve 18, this moment can't be to oil cylinder 9 oilings, and original hydraulic oil flows back to fuel tank 16 through pressure switch SPI 22, solenoid directional control valve YVI 21 in the oil cylinder 9, at this moment disk spring 10 recovers distortion, promotes piston 7 and moves up, and this moment, the tensile force of disk spring 10 recovery distortion forced the tailstock tool chucking.
