Technical Field
The invention relates to the technical field of machining centers, in particular to a universal fixture for a machining center.
Background
The machining center is a numerical control machine tool capable of performing various machining operations on a workpiece within a certain range. However, the surface of the machined workpiece may be an inclined surface, the shape is irregular, the workpiece is difficult to be clamped by the existing clamp, a set of special clamp is developed aiming at the workpieces with different shapes, the cost is high, the time is long, the raw materials of the machined workpiece are various, the development speed of the clamp is far beyond the speed of the shape change of the workpiece, and the clamp which is universal aiming at the workpieces with different shapes is not available at present.
Disclosure of Invention
To the not enough of above-mentioned prior art, the technical problem that this patent application will solve provides a simple structure, and the commonality is strong, and is with low costs, the machining center that facilitates the use uses universal fixturing.
In order to solve the technical problems, the invention adopts the following technical scheme:
the utility model provides a universal fixturing for machining center, includes 2 at least centre gripping subassemblies, the centre gripping unit mount is on machining center's body, the centre gripping subassembly includes the centre gripping cylinder, the cylinder body fixed mounting of centre gripping cylinder has the U-shaped frame, the piston rod of centre gripping cylinder passes the U-shaped frame and is located the U-shaped frame and installs the gear through the wheel carrier rotation, the inside wall fixed mounting of U-shaped frame has the guide way, sliding fit has the guide block in the guide way, fixed surface that the guide block is relative installs first rack and second rack with gear engagement, the clamp splice is installed through the mount pad in the outer end of guide block.
Wherein, the surface of the guide groove provided with the rack is arranged to be inwards protruded.
The clamping block is fixedly connected with the mounting seat and the guide block through bolts through the flange seat.
The cylinder body outer side of the cylinder is fixedly provided with a cylinder seat, and the cylinder seat is fixedly connected with the body of the machining center.
In conclusion, the invention has the advantages of simple structure, strong universality, low cost and convenient use.
Drawings
Fig. 1 is a schematic structural diagram of a universal fixture for a machining center according to the present invention.
Fig. 2 is a front view of fig. 1.
Fig. 3 is a schematic view of two clamps in a state of clamping a workpiece.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings. In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "upper, lower" and "top, bottom" etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be interpreted as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.
As shown in fig. 1-3, a universal fixture for machining center, includes 2 at least centre gripping subassemblies, the centre gripping subassembly is installed on machining center's body, the centre gripping subassembly includes centre gripping cylinder 1, centre gripping cylinder's cylinder body fixed mounting has U-shaped frame 2, centre gripping cylinder's piston rod passes U-shaped frame and is located U-shaped frame and rotates through wheel carrier 3 and install gear 4, U-shaped frame's inside wall fixed mounting has guide way 5, sliding fit has guide block 6 in the guide way, the relative fixed surface of guide block installs first rack 7 and second rack 8 with gear engagement, clamp splice 9 is installed through the mount pad in the outer end of guide block.
Wherein, the surface of the guide groove provided with the rack is arranged to be inwards protruded.
The clamping block 9 is fixedly connected with the mounting seat 12 and the guide block through bolts through a flange seat 11.
The cylinder body outer side of the cylinder is fixedly provided with a cylinder seat, and the cylinder seat is fixedly connected with the body of the machining center.
When carrying out the centre gripping to the work piece, at first the piston rod of centre gripping cylinder stretches out, promote the gear and remove, gear and two rack toothing, move to the work piece simultaneously under the effect of guide block, behind a surface of one of them clamp splice butt work piece, the piston rod of centre gripping cylinder continues to be released, the gear then rotates, promote another rack and drive another clamp splice and remove, until another clamp splice and work piece contact, realize the centre gripping to 2 azimuths of work piece, dispose two anchor clamps at least, realize the centre gripping to dysmorphism piece, convenient processing.
Finally, it should be noted that: various modifications and alterations of this invention may be made by those skilled in the art without departing from the spirit and scope of this invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
