Abstract

The invention discloses an adjustable hydraulic clamping device, which is an auxiliary tool for machining, and overcomes defects of other technology. The adjustable hydraulic clamping device consists of a piston nut, a gland, a clamping oil cylinder, a guide rod gland, an oil cylinder gland, guide rods, an adjusting clamping screw and a clamping plate which are connected, wherein the piston nut is arranged in the clamping oil cylinder and is fixed by the oil cylinder gland; the adjusting clamping screw is arranged in the piston nut and is connected through threads; a linear motion ball bearing is arranged in the clamping oil cylinder and is fixed by the guide rod gland; the guide rods are arranged in the linear motion ball bearing; and the clamping plate connects the two guide rods and the adjusting clamping screw into a whole through nut connection. The adjustment range can be expanded by adjusting the screw; the clamping assistance time can be shortened and the work efficiency can be improved through hydraulic clamping; and the device is suitable for mass production of bearing rings. By adopting the newly designed adjustable hydraulic clamping device, the production cost of bearings is reduced.

Description

A kind of adjustable hydraulic clamping device
One, technical field: the present invention relates to the machining aid, especially a kind of adjustable hydraulic clamping device.
Two, background technology: being clamped in the machine industry of workpiece used very extensive, especially more general in the use of field of machining.The mode of stepping up of workpiece has varied, wherein uses two kinds of screw rod clamping the most generally and hydraulic clamp.The advantage that screw rod clamps is: simple in structure, be easy to make, and adjustable extent is big, and shortcoming is that clamping is long non-cutting time, inefficiency; Hydraulic clamp can remedy the shortcoming that screw rod clamps: shorten clamping non-cutting time, increase work efficiency.It is little that but the shortcoming of hydraulic clamp is an adjustable extent.
Three, summary of the invention: the purpose of this invention is to provide a kind of adjustable hydraulic clamping device that screw rod clamps and hydraulic clamp is integrated; It has solved the shortcoming that other technology exists; The objective of the invention is to realize like this; It is to be formed by connecting on piston unt, gland, clamping oil cylinder, guide post gland, oil cylinder gland, guide post, adjusting clamping screw and clamping plate, and piston unt is installed in the clamping oil cylinder, fixes with the oil cylinder gland; Regulate clamping screw and be installed in the piston unt, with being threaded; Ball bushing is installed in the clamping oil cylinder, fixes with the guide post gland; Guide post is installed in the ball bushing; Clamping plate connect through nut, are one with two guide posts with regulating clamping screw.
Operation principle: the present invention can use in pairs, can use separately also that (fixed according to the field of employment, the shape of clamping plate can change.Because thickness of workpiece differs big (100mm-400mm), during work, can at first use the four directions of spanner rotary-piston nut to regulate clamping screw to locking near workpiece end face 10mm-20mm place; At this moment hydraulic pressure can be started working in the clamping oil cylinder; Through the hydraulic pressure turnover, promote piston unt and move back and forth, drive the adjusting clamping screw and together reciprocatingly move; Because clamping plate connect through nut; Is one with two guide posts with regulating clamping screw, regulates the variable in distance that makes between clamping plate and workpiece end face that moves back and forth of clamping screw, realizes unclamping and clamping work workpiece.
For realizing above-mentioned operation principle, each parts has different effects, realizes different functions.Specific as follows; (1), piston unt: a most important part in the structure, its effect in mechanism has two: in the clamping hydraulic cylinder body, move back and forth as piston rod, realize hydraulic clamp and unclamp; Regulate clamping screw position, the distance of control clamping plate and workpiece end face guarantees clamping reliability.
(2), the clamping oil cylinder: the fundamental parts of mechanism, its effect in mechanism is: the carrier of each part in the mechanism; Confirm the relative position of mechanism and required clamping work pieces, with being fixedly connected of lathe.
(3), gland: use two in the mechanism, its effect in mechanism is: compress two ends Yx RunddichtringO, prevent fluid seepage in the hydraulic cylinder, reduce system pressure in the hydraulic cylinder, influence clamping force.
(4), guide post gland: use two in the mechanism, its effect in mechanism is: guarantee ball bushing tram and not along the axis play in the clamping oil cylinder; J-shaped dust ring and O RunddichtringO are installed, and impurity gets into interior precision and the life-span that influences bearing of ball bushing to prevent that dust, cooling fluid, iron from cutting etc.
(5), oil cylinder gland: its effect in mechanism is: control oil cylinder stroke size; Yx RunddichtringO and O RunddichtringO are installed, are prevented fluid seepage in the hydraulic cylinder, reduce system pressure in the hydraulic cylinder, influence clamping force.
(6), guide post: use two in the mechanism, its effect in mechanism is: in ball bushing, move back and forth, drive clamping plate with the adjusting clamping screw and move back and forth; Guarantee that clamping plate have fixing direction and position, can not depart from the workpiece pressing surface location in company with rotation because of regulating clamping screw.
(7), regulate clamping screw: its effect in mechanism is: come the adjustment stroke size according to need clamping thickness of workpiece; Driving clamping plate with guide post reciprocatingly moves;
(8), clamping plate: its effect in mechanism is: under the effect of hydraulic coupling, clamp or unclamp the workpiece of need clamping.
This device can enlarge adjustable range through the adjustment screw rod; Can pass through hydraulic clamp, shorten clamping non-cutting time, increase work efficiency; Be applicable to and produce bearing ring processing in batches.Adopt newly-designed adjustable hydraulic clamp mechanism, reduced the Production of bearing manufacturing cost.
Four, description of drawings: Fig. 1 is a kind of structural representation of adjustable hydraulic clamping device, among the figure 1, piston unt 2, gland 3, clamping oil cylinder 4, guide post gland 5, oil cylinder gland 6, guide post 7, regulate clamping screw 8, clamping plate
Fig. 2 is a kind of working state figure of adjustable hydraulic clamping device.
Five, the specific embodiment: in Fig. 1 and Fig. 2, piston unt 1 is installed in the clamping oil cylinder 3, and is fixing with oil cylinder gland 5, and an end of regulating clamping screw 7 and piston unt 1 are by being threaded; Ball bushing is installed in the clamping oil cylinder 3, and is fixing with gland 2 with guide post gland 4; Guide post 6 is installed in the ball bushing; Clamping plate 8 connect as one with an end of regulating clamping screw 7 end of two guide posts 6 through nut.
