Abstract
The utility model provides a linear guide rail clamping device of a machine tool, which is characterized in that a hydraulic cylinder is connected with a clamping body via a flange, the clamping body is fixed on a body or worktable of the machine tool, a clamping column is fastened on a piston rod of the cylinder by a gland nut, a clamping rod and a clamping block are fixed on the clamping body via a pin shaft, and a spring is fixed on the clamping body. The device is arranged on the worktable or a stand column of the machine tool, the lever motion of the clamping rod of the device is driven by the reciprocating motion of the hydraulic cylinder so as to clamp the linear guide rail of the machine tool, and due to the large clamping force and good stability, the machining accuracy of the machine tool is improved.
Description
Technical field
The utility model relates to a kind of lathe line slideway clamping device.
Background technology
At present in order to improve the service precision of lathe, greatly machine adopted line slideway guiding and the mode that supports, the advancing and stop to come transferring power and braking of lathe, and Digit Control Machine Tool is to carry out hold mode with servomotor by ball-screw.More than loosening phenomenon is arranged owing to clamping unstable causing, cause in the processing workpiece quality to descend or produce the cutter phenomenon.
Summary of the invention
The purpose of this utility model provides a kind of clamping device of line slideway, this device is installed on workbench or the machine pillar, reciprocating motion by hydraulic jack, drive the lever motion of this device clamping bar, reach clamping action to the lathe line slideway, 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 line slideway 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.Implement clamping action in the dovetail groove of clamp embedding lathe line slideway.
Advantage of the present utility model:
By on platen or lathe bed, installing the line slideway clamper additional, eliminated the unstability that does not have clamper, make lathe that a stable work system be arranged in machining, improve the crudy and the required precision 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 clamp 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, lathe line slideway 9 is provided with dovetail groove, and clamping column 13 usefulness clamp nuts 10 are fastened on the oil cylinder piston bar 3.
This device is by the thrust of hydraulic jack turnover oil, make piston drive pull bar and move back and forth that in motion process, the clamping column 13 on the pull bar compresses and loosens clamping bar 7, drive the opening and closing movement of clamp 8, finish compressing and loosen process lathe line slideway 9 dovetail grooves.Just oil cylinder piston is up when lathe begins processing work, drives piston rod 3, clamping column 13 and up moves, and compresses clamping bar 7 and passes through bearing pin 11 beginnings rotation inward, drives the dovetail groove enforcement clamping action that clamp 8 embeds lathe line slideway 9; After machine cut machines, descent of piston, drive piston rod 3, clamping column 13 move down, clamping bar 7 passes through spring 12 spinning reduction outward, clamp 8 leaves dovetail groove, and lathe line slideway 9 is implemented relaxation state, makes lathe or workbench to move.
