The technical solution of the utility model is as follows: a kind of lathe air tightness detection apparatus, in main shaft (1), wear pull bar (2), the left end of this pull bar (2) is connected with the piston rod of angling cylinder (3), the right-hand member of pull bar (2) is connected with the upper multiple jaws (5) installed of power chuck (4), be fixed with locating piece (7) at the right-hand member of described power chuck (4), the right side of this locating piece (7) is formed with and jaw (5) locating dowel (7a) one to one, be equipped with the bar of supplying gas (6) at the center of described pull bar (2), the left end of this bar of supplying gas (6) stretches out angling cylinder (3), and fix with the cylinder body of angling cylinder (3), the right-hand member of bar (6) of supplying gas extends to the center of multiple locating dowels (7a) circumference that surrounds, above offer passage (6a) along its axial line at the described bar of supplying gas (6), the air inlet of this passage (6a) is communicated with the outlet of air pressure gyrator (8), in air pressure gyrator (8), air gap sensors is housed, the gas outlet of described passage (6a) is communicated with the import of the upper pore arranging of locating piece (7), the number of described pore outlet equates with locating dowel (7a), each outlet is positioned at the right side of corresponding locating dowel (7a).
Adopt above technical scheme, workpiece is close on the right side of the each locating dowel of locating piece by its locating surface, and is clamped by jaw.Gas enters the passage of the bar of supplying gas from air pressure gyrator, then is entered by passage in the pore of locating piece, and gas finally arrives the right side of the each locating dowel of locating piece.If there is gap between workpiece and locating piece, gas is from this clearance leakage, and the air gap sensors in air pressure gyrator detects atmospheric pressure lost, be that alarm workpiece is unkitted and clips to position, lathe does not enter procedure yet, until clamping puts in place again, can process.As can be seen here, the utility model detects workpiece by instrument and numerical control program, and whether clamping puts in place, and gives alarm, can guarantee that clamping workpiece puts in place just can process, and has avoided the waste product producing because clamping workpiece is incorrect completely.
The left end of the described bar of supplying gas (6) is formed with annular boss, the right side of this annular boss and locking nut (9) fit, fix by screw between the two, described locking nut (9) is set on the cylinder body of angling cylinder (3), both threaded engagement.Above structure is simple compact on the one hand, and the bar of can being convenient to supply gas is connected with angling cylinder; On the other hand, supplying gas is connected between bar and angling cylinder not only firmly but also reliable, can not become flexible.
Be provided with anti-rotation support (10) on the side of described air pressure gyrator (8), the tracheae connecting on air pressure gyrator when preventing work rotates; Anti-rotation support (10) is " L " shape, and not only moulding is simple, processing and fabricating is easy, and anti-rotation support on lathe case, install convenient, firm.
Between described locating piece (7) and the bar of supplying gas (6), be provided with O-ring seals, gas does not leak when guaranteeing work.
Beneficial effect: the utility model can be guaranteed that clamping workpiece puts in place and just can process, avoid the waste product producing because clamping workpiece is incorrect completely, have ingenious, simple in structure, easy to detect, the testing result of design accurately and reliably, transformation easily, the feature such as improvement cost is low, be specially adapted to semifinishing and finishing step that accessory size and positional precision are higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, in main shaft 1, wear pull bar 2, both matched in clearance.The left end of pull bar 2 stretches out the left side of main shaft 1, and is connected with the piston rod of angling cylinder 3, and the right-hand member of pull bar 2 is connected with three jaws 5 installing on power chuck 4.The structure of each parts and mounting means are same as the prior art above, do not repeat at this.
As shown in Figure 1, be provided with locating piece 7 on the right side of described power chuck 4, the left side of this locating piece 7 and power chuck 4 fit, and be fixed together, the right side of locating piece 7 is formed with three locating dowel 7a, these three locating dowel 7a press even circumferential and distribute, and corresponding one by one with jaw 5.
As shown in Figure 1, be equipped with at the center of described pull bar 2 bar 6 of supplying gas, this left end of supplying gas bar 6 stretches out angling cylinder 3, the left end of bar 6 of supplying gas is formed with annular boss, the right side of this annular boss and locking nut 9 fit, fix by screw between the two, described locking nut 9 is set on the cylinder body of angling cylinder 3, both threaded engagement.The right-hand member of the described bar 6 of supplying gas is through the centre bore of locating piece 7 and extend to the center of three locating dowel circumference that 7a surrounds, at described locating piece 7 and supply gas and be provided with O-ring seals between bar 6.
As shown in Figure 1, on the described bar 6 of supplying gas, offer passage 6a along its axial line, the air inlet of this passage 6a left end is communicated with the outlet of air pressure gyrator 8.Air pressure gyrator 8 is installed on the left part of the bar 6 of supplying gas, both axis, are equipped with air gap sensors point-blank in air pressure gyrator 8, and are provided with anti-rotation support 10 on the side of air pressure gyrator 8, this anti-rotation support 10 is " L " shape, is installed on lathe case by bolt.The gas outlet of described passage 6a right-hand member is communicated with the import of the pore arranging on locating piece 7, and the number of described pore outlet equates also corresponding one by one with locating dowel 7a, and each outlet is positioned at the right side of corresponding locating dowel 7a.
