Description
Technical field
The invention belongs to lathe technical field, specifically, the particularly air tightness detection apparatus on lathe.
Background technology
During lathe in machining part, clamping workpiece, on chuck, requires workpiece locating surface to be adjacent to chuck locating surface, and to guarantee that workpiece spindle is to accurate positioning, workpiece radially loading just.But in practical operation, whether workman is difficult to see clearly workpiece with naked eyes and is adjacent to, cannot guarantee that each part clamping workpiece puts in place, causing most probably the part of processing is waste product.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of lathe air tightness detection apparatus that can guarantee that clamping workpiece puts in place.
Technical scheme of the present invention 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 a plurality of jaws (5) installed of power chuck (4), right-hand member at described power chuck (4) is fixed with locating piece (7), the right side of this locating piece (7) is formed with and jaw (5) locating dowel (7a) one to one, at the center of described pull bar (2), be equipped with the bar of supplying gas (6), 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 a plurality of locating dowels (7a) circumference that surrounds, at the described bar of supplying gas (6), above along its axial line, offer passage (6a), 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 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 in the pore that enters locating piece by passage, gas finally arrives the right side of 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 present invention 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, by screw, fix 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, between supply gas bar and angling cylinder, be connected not only firmly but also reliable, can not become flexible.
On the side of described air pressure gyrator (8), be provided with anti-rotation support (10), 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 present invention can guarantee that clamping workpiece puts in place and just can process, avoided 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 invention.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
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, at this, do not repeat.
As shown in Figure 1, on the right side of described power chuck 4, be provided with locating piece 7, 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, at the center of described pull bar 2, be equipped with the 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, by screw, fix 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, along its axial line, offer passage 6a, 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, by bolt, is installed on lathe case.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.
Operation principle: during work, workpiece 11 is close on the right side of locating piece 7 each locating dowel 7a by its locating surface, and is clamped by jaw 5.Gas enters the passage 6a of the bar 6 of supplying gas from air pressure gyrator 8, then in the pore that enters locating piece 7 by passage 6a, gas finally arrives the right side of locating piece 7 each locating dowel 7a.If there is gap between workpiece 11 and locating piece, gas is from this clearance leakage, and the air gap sensors in air pressure gyrator 8 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.
