Description
Technical field
The present invention relates to a kind of toolroom machine structure of machining, particularly relate to a kind of processing method of tool machine spindle dust guard and the tool machine spindle of tool dust guard.
Background technology
The structure of the rotary main shaft of existing machinery machining machine and tool disposes as shown in Figure 5, and this rotary main shaft includes an axostylus axostyle 50, an axle bed 60 in order to support axostylus axostyle 50, and the CD-ROM drive motor 70 of a connection drive shaft rod 50; Wherein, axle bed 60 is installed on the board A inside of toolroom machine and is fixedly connected on CD-ROM drive motor 70, axostylus axostyle 50 is installed on axle bed 60 with rotatable form, one end of axostylus axostyle 50 directly places the rotor 71 that is fixed in CD-ROM drive motor 70, rotating by the direct drive shaft rods 50 of CD-ROM drive motor 70, and at an end that passes board A in conjunction with being provided with a process tool B.
For avoiding in process; the foreign matters such as metal fines that turning liquid, dust and processing produce; may invade between rotating axostylus axostyle 50 and the fixed axle bed 60; and then influence the smoothness and the security of axostylus axostyle 50 running, usually can axostylus axostyle 50 outwardly the processing end and axle bed 60 between one group of dust guard 90 is set.As Fig. 5 and shown in Figure 6, existing dust guard 90 comprises and abutting mutually and an end cap 91 and a dust cap 92 that contour shape is complementary; Wherein, end cap 91 is incorporated into the openend of axle bed 60 with screw thread, and pushes against the bearing 61 that is arranged between axostylus axostyle 50 and the axle bed 60; Dust cap 92 is incorporated into the processing end of axostylus axostyle 50 with screw thread, and be arranged with an annular groove 921 that embeds for end cap 91 towards the end face of end cap 91 at dust cap 92, the specification of annular groove 921 is slightly larger than end cap 91, can between end cap 91 and dust cap 92, reserve a little gap, produce contact friction in case not-go-end lid 91 and dust cap 92 are interfered mutually.
For water proof and dust proof is considered, gap between end cap 91 and the dust cap 92 should dwindle as much as possible, but be subject to following two kinds of factors, cause this gap to be difficult to dwindle effectively: (one) existing dust guard 90 is made with turning machine-shaping, and precision is subjected to certain restriction; (2) interfere the smoothness that influences rotation with axle bed 60 when avoiding axostylus axostyle 50 to rotate, this gap must be enough greatly; (3) avoiding cutting small foreign bodies such as particle invades this gap and stuck phenomenon takes place.Based on aforementioned every factor, existing labyrinth type dust guard 90 is arranged at gap between end cap 91 and the dust cap 92 greatly about about the scope of 0.15mm to 0.5mm, when general running is implemented, utilize centrifugal force and cyclogenesis, can also reach and run well and the dustproof and waterproof effect, but when the cutting environment is abominable, for example: the water yield of cutting fluid is excessive or hydraulic pressure is excessive or cutting particle during less than 0.15mm, existing dust guard 90 pollutes bearing with regard to easy generation foreign matter penetration phenomenon, be accumulated to a certain amount of after, can take place just that bearing wear was lost efficacy and problems such as smoothness are rotated in influence.
