Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1, the structure of the present invention is schematically illustrated:
the utility model provides a clamping device containing right-angled block bodies for aviation part processing, which comprises a device seat body 1, a pressing block 4 and a bolt 5, wherein the upper end of the device seat body 1 is provided with a rectangular positioning groove 2, the positioning groove 2 is used for placing part block bodies, and threaded holes 3 are distributed in the upper part, the lower part, the left part and the right part of the positioning groove 2 and in the positioning groove 2; the bolts 5 penetrate through the compression blocks 4 and are in threaded connection with the threaded holes 3, and the number of the compression blocks 4 is at least three.
The principle is as follows: through the rectangular positioning groove 2, a part with a right angle is placed at one corner of the positioning groove 2, two right-angle sides of the positioning groove 2 can position the part, then the pressing block 4 is installed, one end of the pressing block 4 is pressed on the part, at least three pressing blocks 4 respectively press the part from three directions, and the part can be prevented from running in the machining process; after the device is installed on a machine tool, the origin of coordinates of the device is fixed, and the device is easy to align a cutter and a part, so that various characteristics of the end face of the part are machined. In addition, also can compress tightly in constant head tank 2 with unnecessary compact heap, contradict the part side, improve stability.
The utility model has simple structure and easy manufacture, one device can adapt to the processing of parts with different sizes, thereby reducing the processing cost and saving the processing time; the parts are positioned by the right-angle side of the positioning groove 2, so that the alignment is convenient and the processing precision is high; through distributing threaded hole 3 to compact heap 4 compresses tightly the part from a plurality of directions, and part block centre gripping is stable, does not produce the drunkenness.
The device housing 1 is rectangular plate-shaped. The magnetic force adsorption and clamping device can be fixed on a machine tool in a magnetic force adsorption and clamping mode, the position is easy to determine, the alignment is convenient, and the accuracy is high.
The pressing block 4 is provided with a long waist hole 6, and the bolt 5 penetrates through the long waist hole 6. The pressing block 4 is convenient to operate to advance and retreat, the length of the pressing block 4 lapped on a part block body is adjusted, the clamping stability is ensured, and meanwhile, the cutter interference is prevented; simultaneously, owing to fix a position through the right angle limit of constant head tank 2, the compact heap 4 at constant head tank 2 edge is used for compressing tightly the part, and compact heap 4 in the constant head tank 2 can be tighter, even consider compact heap 4 to have the slope along 6 directions in long waist hole, does not influence the stability of part yet.
And the bolt 5 is also sleeved with a compression ring 7. The pressing block 4 is pressed through the pressing ring 7, the influence of the long waist hole 6 is reduced, and the pressing block 4 at the edge of the positioning groove 2 is prevented from inclining.
