Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.But the purposes of these exemplary embodiments and purpose Only being used for enumerating the present invention, not the real protection scope to the present invention constitutes any type of any restriction, more non-by this Bright protection domain is confined to this.
In the present invention, when parts are referred to as " being fixed on " another parts, it can be directly at another zero On part, or parts placed in the middle can also be there are.When parts are considered as " connection " another parts, and it is permissible It is directly to another parts or may be simultaneously present parts placed in the middle.When parts are considered as " to arrange In " another parts, it can be to be set directly on another parts or may be simultaneously present parts placed in the middle.
Suitably with reference to shown in Fig. 1 and Fig. 2, the actuating device of the basic embodiment that the present invention provides, including air supporting part and Housing parts;Air supporting part includes: screw rod 1, ring-shaped graphite 3, gas source connector 4 and air supporting fixture 6, ring-shaped graphite 3 is relatively Being arranged on the both sides of air supporting fixture 6, gas source connector 4 is arranged on air supporting fixture 6, and air supporting fixture 6 is provided with connection gas Source joint 1 and the air flue of ring-shaped graphite 3, screw rod 1 and air supporting fixture 6 drive connection;Housing parts includes: left end cap 7, c-type Ring 8 and right end cap 9;Left end cap 7 and C-shaped ring 8 and right end cap 9 form the space accommodating air supporting part.
Preferably, air supporting fixture 6 is provided with annular groove, and ring-shaped graphite 3 is arranged in annular groove.
Preferably, also include that pipe joint 5, pipe joint 5 are connected with gas source connector 4.
Preferably, gas source connector 4 is through C-shaped ring 8.
The central axis of screw rod 1 passes left end cap 7 and right end cap 9.The axis of ring-shaped graphite 3 passes left end cap 7 and the right side End cap 9.
Housing parts is positioned on feed screw nut seat, and offers M5 via and M5 screw thread in connecting rod 10 on feed screw nut seat Hole is fixed, and the other end long slot bore of connecting rod 10 is fixed with right end cap 9, and left end cap 7 and right end cap 9 are fixed in C-shaped ring 8, also Including connecting rod 10, connecting rod 10 and screw rod 1 are separately positioned on left end cap 7 and form receiving air supporting portion with C-shaped ring 8 and right end cap 9 Point the both sides in space, and connecting rod 10 is connected with left end cap 7 or right end cap 9.
Preferably, also include that oscillating bearing 2, air supporting fixture 6 are connected by oscillating bearing 2 with screw rod 1.
Double air supporting parts are positioned on slide carriage, and the screwed hole offering a M6 on slide carriage surface is connected with M6 screw rod 1, M6 Screw rod 1 is attached with oscillating bearing 2 female thread, and the other end M6 screw rod 1 of oscillating bearing 2 is connected with air supporting fixture 6, two Ring-shaped graphite 3 is fixed on the both sides of air supporting fixture 6, and M6 pipe joint adaptor is arranged at the side of air supporting fixture 6, PC6-M5 Pipe joint is attached with M6 pipe joint adaptor.
Preferably, housing upper is provided with dust excluding plate 11, and left end cap 7 is formed by dust excluding plate 11 with C-shaped ring 8 and right end cap 9 Accommodating the space-closed of air supporting part, dust excluding plate 11 offers circular hole on surface, and this circular hole is carried out with left end cap 7 and right end cap 9 Connecting, prevent in the gap that dust and flying chip enter between graphite and end cap, above structure just constitutes housing parts.
When source of the gas is passed on air supporting fixture 6 by PC6-M5 pipe joint and pipe joint adaptor, air supporting fixture 6 In source of the gas is just assigned to the cannelure of both sides by through hole and then pass on ring-shaped graphite 3, the ring-shaped graphite 3 of such both sides just with a left side Defining one layer of gas mould between end cap 7, right end cap 9, this layer of gas mould thickness is about 0.01mm, and this connected mode has broken routine Part and part between rigid connection mode, eliminate the vibrations brought of feed screw nut seat, slide carriage passes through joint shaft Holding 2 to be connected with air supporting fixture 6, above structure just constitutes double air supporting part.Therefore when feed screw nut seat advances, housing section The slide carriage promoting double air supporting part to be connected inside the right end cap divided advances, when feed screw nut seat retreats, and a left side for housing parts The slide carriage pulling double air supporting part to be connected inside end cap 7 retreats.
