Abstract

The utility model provides a clamping device for a ball screw of a machine tool. The clamping device is characterized in that a hydraulic oil cylinder is connected with a clamping body through a flange; the clamping body is fixed on a machine tool part corresponding to the ball screw; clamping rods and clamping blocks are fixed on the clamping body through pin shafts; and springs are fixed on the clamping body. The device is arranged on the machine tool part corresponding to the ball screw, levers of the clamping rods of the device are driven by the reciprocating movement of the hydraulic oil cylinder to move , thus, the function of clamping the ball screw of the machine tool can be achieved; and the device has a large clamping force and good stability, therefore, the machining precision of the machine tool can be improved, and the service life of the screw can be prolonged.

Description

Lathe ball-screw clamping device
Technical field
The utility model relates to a kind of lathe ball-screw clamping device.
Background technology
At present in order to improve the service precision of lathe, machine adopted the ball screw assembly, mode that drags and support process, the parts of lathe are advanced and are stopped to come transferring power and braking by driving ball-screw, Digit Control Machine Tool is a usefulness servomotor brake system hold mode.More than owing to clamp when instability causes loosening rotation phenomenon arranged, and the oscillation phenomenon that produces on guide rail during lathe work easily causes in the processing workpiece quality to descend or make the improper motion of leading screw cause machine finish to reduce because of external influence power (certain axle system) effect.
Summary of the invention
The purpose of this utility model provides a kind of lathe ball-screw clamping device, this device is installed on the corresponding machine tool component of ball-screw, reciprocating motion by the hydraulic cylinder piston axle, drive the lever motion of this device clamping bar, reach clamping action to the lathe ball-screw, because of its chucking power is big, good stability is so can improve the machining accuracy of lathe.
The technical scheme that realizes the utility model purpose is: a kind of lathe ball-screw clamping device, hydraulic jack links to each other with the clamping body by flange, clamp body by on the lathe bed or workbench that are bolted to lathe in the pin in the pinhole, the bolt hole, clamping column is fastened on the oil cylinder piston bar with clamp nut, clamping bar and clamp are fixed on by bearing pin and clamp on the body, and spring is fixed on and clamps on the body.
Wherein clamp directly clamps the ball-screw enforcement clamping action of lathe.
Advantage of the present utility model:
By the ball-screw clamping device is installed, eliminated the unstability that does not have clamping device, make lathe that a stable work system be arranged in machining, improve the crudy and the requirement on machining accuracy of workpiece.
Description of drawings
Fig. 1 is the structural representation of the utility model clamping device.
The specific embodiment
As shown in Figure 1: hydraulic jack 1 links to each other with clamping body 4 by flange 2, clamp body 4 by on the lathe bed or workbench that are bolted to lathe in the pin in the pinhole 5, the bolt hole 6, clamping bar 7 and clamping fast 8 are fixed on by bearing pin 11 and clamp on the body 4, spring 12 is fixed on and clamps on the body 4, and clamping column 13 usefulness clamp nuts 10 are fastened on the oil cylinder piston pull bar 3.
This device is by the thrust of hydraulic jack 1 turnover oil, making piston drive pull bar moves back and forth, in motion process, clamping column 13 on the pull bar compresses and loosens clamping bar 7, drive clamp 8 opening and closing movements, clamp 8 directly clamps the ball-screw 9 of lathe and implements clamping actions, finishes compressing and loosen process lathe ball-screw 9.Just when lathe began processing work, oil cylinder piston was up, drove piston rod 3, clamping column 13 and up moved, and compressed clamping bar 7 and passed through bearing pin 11 beginnings rotation inward, drove and clamped fast 8 clamping ball-screws; After machine cut machines, descent of piston, drive piston rod 3, clamping column 13 move down, and clamping bar 7 passes through spring 12 spinning reduction outward, clamps fast 8 and unclamps, and lathe ball-screw 9 is implemented relaxation states, makes lathe or workbench to move.
