Description
Technical Field
The utility model relates to a digit control machine tool milling process anchor clamps.
Background
In the field of numerical control milling, two clamping modes are generally adopted at present:
firstly, a white positioning block is bonded on a machine tool, then a plane is milled on the white positioning block through the machine tool, then a part is placed on the machine tool and aligned to a milled reference surface, and then the part is bonded and fastened through glue. The disadvantages of this method are: the positioning can not be repeated, and the glue treatment is troublesome.
And secondly, customizing the stool for clamping the lower drawing, fastening the lower end of the stool with a T-shaped groove through bolts, fastening the part on the stool through a pressing plate at the upper end, and aligning and presetting coordinates before fastening. The disadvantages of this method are: the relative time spent of flare-outing is longer, and personnel's operation level requires highly, and displacement takes place easily in the fixed process, leads to the precision to reduce, especially in the used repeatedly, can cause the life-span influence to the anchor clamps itself to the anchor clamps external force that apply of flare-outing process repeatedly.
Disclosure of Invention
The utility model aims at solving the problem that the existing numerical control milling machine carries out non-batch large-scale part processing, the alignment clamping operation is complicated, the period is long, and the error is large.
The utility model discloses the technical scheme who adopts specifically as follows:
a numerical control machine tool fixture: mainly comprises a main body module, a replaceable reference block 5, a cast aluminum square box 8, a square box fixed pressing plate 9 and a tensioning nut 12,
the main body module is in a strip shape, round holes are formed in two ends of the main body module, the outer contour of the main body module is in a concentric arc shape, the high-precision sliding bearing 2 is installed in the round holes, the magnetic base 7 is installed in the high-precision sliding bearing 2, and a coordinate setting hole 6 is formed beside the magnetic base 7; the main body module is arranged in a T-shaped groove 10 of a processing platform 11, a chip removal flow groove is formed in the lower bottom surface of the main body module, a replaceable reference block 5 is arranged on the upper surface of the main body module, a boss is arranged on the side surface of the main body module, and a plurality of mounting reference holes 3 which are equidistant are formed in the boss;
the side surface of the aluminum casting square box 8 is provided with a sliding chute which is matched and connected with the side surface of the main body module by a boss; the lower surface of the cast aluminum square box 8 is opened and is fixedly arranged in a T-shaped groove 10 on a processing platform 11 through a square box fixing pressure plate 9 and a tensioning nut 12.
Has the advantages that:
1. through the utility model discloses the reducible strike of the other side case in-process of flare-outing of anchor clamps flare-outing prolongs square chest life.
2. The main part module need not the secondary calibration when rotating, and the coordinate can be flare-outed in single lathe motion, and new staff is last to hand fast, easy operation.
3. The loading and unloading are convenient, no machining interference exists on five axes of the numerical control machining tool, and secondary disassembly and assembly are convenient.
4. The clamp is also suitable for other equipment, and can be matched for use by simply transforming the original square box.
5. After the model is disassembled, the module can not be disassembled, and the original coordinates can be directly used in secondary processing;
6. the magnetic base is fixed by the main body module in machining, the magnetic base has no acting force, and the magnetic base can be loosened after the model is fixed by a single-time machined part.
