The specific embodiment
Come the utility model is described in more detail below in conjunction with specific embodiment.It will be appreciated by those skilled in the art that these embodiments have only enumerated some specific embodiment of the utility model, the utility model and protection domain thereof are not had any restriction.
Please refer to Fig. 2, a pneumatic chip removal device that embodiment provided of the present utility model mainly comprises sealing drum and air inlet pipe 50.The sealing tube can comprise upper sleeve gasket 30 and lower sleeve gasket 40, and this upper sleeve gasket 30 and lower sleeve gasket 40 are fixed together after sealing gasket (for example, Rubber washer) 60 is set between them.This fixedly connected the connection by for example screw realizes.
Upper sleeve gasket and lower sleeve gasket in the sealing tube are respectively charged into sealing ring (for example, rubber matrix sealing ring) 31 and 41.Especially, sealing circle 31 can be arranged in the upper sleeve gasket 30, and sealing circle 41 can be arranged in the lower sleeve gasket 40.The bearing (for example, ball bearing) 32 and 42 of also can between sealing ring 31 and 41, packing into, and the spacing collar 70 with peripheral groove separates between these two bearings 32 and 42.
This air inlet pipe 50 can be installed on the lower sleeve gasket 40 by sealing means.For example, air inlet pipe 50 is welded on the lower sleeve gasket 40.Certainly, this air inlet pipe 50 also can be installed on the upper sleeve gasket 30 by sealing means.The air inlet 51 of this air inlet pipe 50 can be connected with flexible pipe (figure does not show), and this flexible pipe then is connected with compressed air source (figure does not show).
In the use of pneumatic chip removal device of the present utility model, the upper end can be shut and the hollow knife bar 25 of the side perforate sealing tube of packing into from the lower end, and 40 sealings contact with lower sleeve gasket with this hollow knife bar 25 and this upper sleeve gasket 30 with 41 to make sealing ring 31.The upper end of knife bar 25 is contained on the collet 23 of drilling machine or milling machine.Cold cutter (for example, drill bit or boring and milling cutter) 21 in the band is installed in the lower end of knife bar 25.Like this, make to form between the endoporus 211 of the hollow bulb 251 of inner chamber, knife bar 25 of air inlet pipe 50, sealing drum and cutter 21 and be communicated with.The sealing tube can be leaned against on the slide bar (figure does not show) that is fixed on the lathe by air inlet pipe 50.After lathe started, knife bar 25 rotated in sealing drum.This bearing 32 and 42 can be used for preventing that this knife bar 25 from driving the sealing tube and rotating together.The sealing tube can lean against and only do slide mobile (for example, moving up and down) on the slide bar under the drive of sealing tube.Compressed air enters sealing drum from compressed air source through flexible pipe and air inlet pipe 50, and and then enters the hollow bulb 251 of knife bar 25 and the endoporus 211 of cutter 21.Compressed air is finally sprayed by the puff prot 213 of cutter 21 heads, thereby cools off cutter 21, and the machining hole 101 of smear metal from alloy material (for example, carbide alloy semi-finished product) 100 blown out.
Can be understood that pneumatic chip removal device of the present utility model promptly forms hole of the present utility model process equipment after fitting together with knife bar 25.
Again referring to Fig. 3 and Fig. 4, shown the schematic diagram that adopts the carbide alloy workpiece 300 that hole of the present utility model process equipment processed.As an example, in order to be that 50 millimeters, high (H) are that to process four degree of depth (D1) on 30 millimeters the carbide alloy semi-finished product be that 15 millimeters, diameter (D2) are 10 millimeters tapped blind hole 301 at a block length (L) and wide (W), pneumatic chip removal device of the present utility model can be installed in model for example on the hollow knife bar for the CNC milling machine of XK6325B, forms the hole process equipment.Compressed air enters knife bar by pneumatic chip removal device of the present utility model, and by the cutter head ejection, processing is finished in clean powder is blown out in the hole in brill or boring at last, obtains four required tapped blind holes 301 again.
It will be apparent to those skilled in the art that hole process equipment, can add man-hour, smear metal is discharged from the aperture of blind hole or deep hole the carbide alloy semi-finished product by adopting above-mentioned pneumatic chip removal device and adopting this pneumatic chip removal device.Thereby, avoided can not discharging the damage that is caused to workpiece or cutter because of smear metal.
Above with reference to description of drawings embodiment more of the present utility model, but only otherwise deviate from essence of the present utility model and scope, those skilled in the art can carry out modifications and changes on the various forms to it.
