Abstract
The utility model relates to a clamping device, in particular to an adjustable machining chuck. The adjustable machining chuck comprises chuck bodies, positioning through holes formed in the chuck bodies, and a positioning rod, wherein the positioning rod is cooperated with the chuck bodies by the positioning through holes and is fixed by a positioning nut; each positioning through hole is a track-type through hole; the inner surface of each positioning through hole is provided with internal threads; the positioning rod is sheathed with an elastic device. After the structure is adopted, the chuck bodies and the positioning rod are cooperated, the travel of a fixture can be effectively regulated according to the size of a workpiece so as to realize favorable fixing, and the adjustable machining chuck also has strong clamping effect for an irregular-shaped special workpiece of which only the local part can be clamped.
Description
Technical field
The utility model relates to a kind of clamping device, particularly a kind of adjustable machined chuck.
Background technology
In machining process, often need to be to out-of-shape, only have part to be carried out clamping by the workpiece of the special workpiece of clamping or special material, more especially need to carry out the workpiece of multiple exchanging position clamping, traditional clamping device is due to the deficiency self designing, be not easy to realize accurate location and clamp reliably, having affected carrying out smoothly of next process.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of device that can realize accurate location and reliable clamping.
For solving above-mentioned technical problem, adjustable machined chuck of the present utility model, comprises chuck body, is located at the positioning through hole on chuck body, the backstay that coordinates by positioning through hole and fixed by positioning screw cap with described chuck body; Described positioning through hole is racetrack through hole, and described positioning through hole inner surface is provided with internal thread; On described backstay, overlap flexible device.
Further, described elastic device can be rubber sleeve.
Further, described elastic device can also be stainless steel elastic component.
Further, the medial surface that described chuck body contacts with workpiece is provided with anti-skid wearable coating.
Further, described backstay is provided with external screw thread.
Adopt after said structure, by the cooperation of chuck body and backstay, can effectively adjust according to the dimensional requirement of workpiece the stroke of fixture, thereby realize good fixing, for out-of-shape, only have part by the special workpiece of clamping, to there is equally stronger clamping effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of chuck body;
In figure: 1 is chuck body, 2 is positioning through hole, and 3 is backstay, and 4 is microscler through hole, and 6 is positioning screw cap
The specific embodiment
As shown in Figures 1 and 2, adjustable machined chuck of the present utility model, comprise two chuck bodies 1, be located at the positioning through hole 2 on chuck body 1, two backstays 3 that coordinate by positioning through hole 2 with described chuck body 1 and fixed by positioning screw cap 6, wherein, described backstay 3 is provided with external screw thread, convenient and swift when such fixed form makes to operate; Described positioning through hole 2 is racetrack through hole, and described positioning through hole 2 inner surfaces are provided with internal thread, and backstay 3 can be along positioning through hole 2 side-to-side movements, and chuck body 1 also can move up and down along backstay, reaches the object that regulates distance between two backstays.During use, to be held workpiece is placed in two chuck bodies 1 and two formed spaces of backstay 3, then adjust distance between two chuck bodies 1 and two backstays 3 to adapt to the size of workpiece, after adjusting, by positioning screw cap 6, do last adding and fasten.On described backstay 3, overlap flexible device, the setting of elastic device is played booster action for last being fixedly clamped, and makes location more accurately firm.
Further, described elastic device can be rubber sleeve.
Further, described elastic device can also be stainless steel elastic component.
Further, the medial surface that described chuck body 1 contacts with workpiece is provided with anti-skid wearable coating, anti-skid wearable coating can increase the frictional force between chuck body 1 and workpiece, and such setting has been played great facilitation for the clamping of workpiece, has also extended the service life of chuck.
