Description
Technical field
The utility model is related to a kind of fixture, specifically a kind of clamping tool for machine work.
Background technology
Fixture refers to being used for fixing processing object during machine-building, is allowed to occupy correct position, to receive to apply
Work or the device of detection.When machining a workpiece on a machine tool, to make the surface energy of workpiece reach size, geometry as defined in drawing
And required with technologies such as the relative-position errors of other surfaces, workpiece must be installed to (positioning) before processing, clip (folder
Tightly).
Fixture in the prior art is also easy to produce inclination or shift phenomenon when work piece is clamped, and reduces processing production
The precision of product, in processing some ring-shaped work pieces, especially bearing, positioning accuracy inconvenient to use using general fixture or hanger
It is not high, influence Workpiece Machining Accuracy, it is easy to the end face of axle sleeve to be processed be weighed wounded, the quality of axle sleeve processing is affected.
Invention content
The technical problem to be solved by the present invention is to provide a kind of clamping tool for machine work, realize more stable fixation.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of clamping tool for machine work, including frame, frame are equipped with guide rail, and guide rail is equipped with active chuck, is set on frame
There are the fixed chuck for facing active chuck, the active chuck to be equipped with withstanding tight block, elastic collet is installed on fixed chuck,
It is equipped in elastic collet and squeezes slot, the side wall upper part of elastic collet is equipped with step screens, the both sides respectively setting one of elastic collet
Regulating mechanism, the regulating mechanism include screw rod, nut and rotating handle, and fixed chuck is equipped with groove, and it is recessed that screw rod is installed in this
In slot, nut is sleeved on screw rod, and screw rod one end is exposed to be connect outside fixed chuck and with rotating handle, screw rod other end face
The step screens of elastic collet, the withstanding tight block of active chuck faces elastic collet.
One end that the screw rod faces step screens is installed with rubber sheet gasket.
The extruding slot is conical hole slot.
The side wall for squeezing slot is equipped with workpiece screens.
Banking stop is equipped in the groove of the fixed chuck.
The front end face of the withstanding tight block is equipped with elastic buffering pad.
The utility model utilizes the clamping of upper grip and lower collet, while using the fixation of elastic collet, realizing to workpiece
Stabilization fixation, improve the accuracy of processing.
Description of the drawings
Attached drawing 1 is the utility model section schematic diagram.
Specific implementation mode
For that can further appreciate that the feature, technological means and the specific purposes reached, function of the utility model, below
The utility model is described in further detail with specific implementation mode in conjunction with attached drawing.
As shown in Fig. 1, the utility model discloses a kind of clamping tool for machine work, including frame 2, and frame 2 is equipped with and leads
Rail 1, guide rail 1 are equipped with active chuck 4, and frame 2 is equipped with the fixed chuck 14 for facing active chuck 4, the active chuck 4
It is equipped with withstanding tight block 5, elastic collet 13 is installed on fixed chuck 14, is equipped in elastic collet 13 and squeezes slot 11, elastic collet
13 side wall upper part is equipped with step screens 15, and respectively one regulating mechanism of setting, the regulating mechanism include for the both sides of elastic collet 13
Screw rod 8, nut 9 and rotating handle 10, fixed chuck 14 are equipped with groove 1, and screw rod 8 is installed in the groove 1, and nut 9 is set with
On screw rod 8,8 one end of screw rod is exposed outer in fixed chuck 13 and is connect with rotating handle 10, and 8 other end of screw rod faces elasticity
The withstanding tight block 5 of the step screens 13 of collet 14, active chuck 4 faces elastic collet 13.Active chuck is moved along guide rail, real
Now between fixed chuck it is close with it is separate.
One end that the screw rod 8 faces step screens 15 is installed with rubber sheet gasket 7, passes through rubber sheet gasket 7 and step card
Position 15 contacts, and avoids being in direct contact for screw rod and step screens, is damaged to be not easy to generate elastic collet.
The extruding slot is conical hole slot, can preferably be deformed.
The side wall for squeezing slot 11 is equipped with workpiece screens 12, can be by the more firm placement of workpiece.
It is equipped with banking stop 16 in the groove 1 of the fixed chuck 14, prevents screw rod from falling off from groove.
The front end face of the withstanding tight block 5 is kept away equipped with elastic buffering pad 6 by the good workpiece of elastic buffering pad compression fit
Exempt from that workpiece is caused to damage.
In the utility model, workpiece is first squeezed into assembly in the extruding slot of elastic collet, slot is squeezed and is squeezed by workpiece
It presses and extends out.For a part of workpiece, it is only necessary to by the elasticity of elastic collet itself can stablize by Workpiece clamping；For
Part workpiece then also needs to the compression that horizontal direction is realized by the effect of screw rod.Rotating handle is rotated, so that screw rod is rotated, band
Dynamic screw rod moves and then is resisted towards elastic collet step screens and realize and holds out against.Active chuck is set to be moved to fixed chuck again,
The workpiece squeezed in slot for being clamped at elastic collet is realized from vertical direction and is compressed.
It should be noted that these are only the preferred embodiment of the utility model, it is new to be not limited to this practicality
Type, although the utility model is described in detail with reference to embodiment, for those skilled in the art, still
It can modify to the technical solution recorded in previous embodiment or equivalent replacement of some of the technical features,
But within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the scope of protection of the utility model.
