Oil injector and sliding device thereof

Abstract

The oil injector of this invention includes a first body and a second body. The first body has a first oil inlet, a first lower channel communicating with the first oil inlet and having a communicating groove, and two through holes penetrating the upper and lower surfaces of the first body. The second body is tightly fitted to the first body and has an upper channel. The upper channel has an oil inlet portion communicating with the communicating groove and two oil outlet portions respectively communicating with each of the through holes. Each oil outlet portion and the oil inlet portion have the same channel length. Thus, the oil injector of this invention can collect lubricating oil into the oil inlet portion, and then uniformly inject oil into each slider of the linear drive module through equal-length channels. Furthermore, this invention also provides a sliding device having the aforementioned oil injector and a platform for accommodating the oil injector.

Claims

1. An oil injector, comprising: a first body having at least one first oil inlet located on a side of the first body, a first lower flow channel communicating with the at least one first oil inlet, and two through holes penetrating the upper and lower surfaces of the first body and not communicating with the first lower flow channel, the first lower flow channel having a connecting groove with an opening located on the upper surface of the first body; and a second body disposed on the upper surface of the first body and having an upper flow channel, the upper flow channel having an oil inlet portion communicating with the connecting groove, and two oil outlet portions respectively communicating with each of the through holes, wherein each oil outlet portion and the oil inlet portion have the same flow channel length.

2. The oiler as described in claim 1, wherein, The first body has at least one second oil inlet located on the side of the first body, a second downstream channel communicating with the at least one second oil inlet but not communicating with the first downstream channel and each of the perforations, and an oil outlet communicating with the second downstream channel; the second body has an oil receiving member communicating with the oil outlet.

3. The oiler as described in claim 1, wherein, Both the first body and the second body have a transverse cross-section resembling the letter "I".

4. A sliding device with an oiler, comprising: an oiler having a first body and a second body, the first body having at least one first oil inlet located on the side of the first body, a first lower flow channel communicating with the at least one first oil inlet, and two through holes penetrating the upper and lower surfaces of the first body and not communicating with the first lower flow channel, the first lower flow channel having a connecting groove with an opening located on the upper surface of the first body, and the second body being disposed on the upper surface of the first body and having an upper flow channel, the upper flow channel having an oil inlet communicating with the connecting groove, and two oil outlets respectively communicating with each of the through holes, wherein each oil outlet and the oil inlet have the same flow channel length; A platform having a mounting groove for receiving the oiler, the mounting groove having two openings that extend through the mounting groove and through the lower surface of the platform, such that when the oiler is received in the mounting groove, each of the openings is exposed to the lower surface of the platform; and a plurality of sliders located below the platform, each having a slider oil inlet communicating with one of the openings.

5. The sliding device with an oiler as described in claim 4 further includes an oiling conduit having an inlet end and an outlet end; the first body having at least one second inlet located on the side of the first body, a second downstream channel communicating with the at least one second inlet but not communicating with the first downstream channel and each of the perforations, and an outlet communicating with the second downstream channel; the second body having an oil receiving member communicating with the outlet and the inlet end of the oiling conduit; the platform having a nut located below the platform, the nut having a nut oiling port communicating with the outlet end of the oiling conduit.

6. The sliding device with an oiler as described in claim 5, wherein, The platform has at least two oil injection channels that extend from the mounting groove through the side of the platform. When the oil injector is placed in the mounting groove, the at least one first oil inlet and the at least one second oil inlet are respectively accommodated in the at least two oil injection channels.

7. The sliding device with an oiler as described in claim 5, wherein, The platform has an oil outlet channel that extends from the mounting slot through the side of the platform. When the oil injector is housed in the mounting slot, the oil injection conduit is placed in the oil outlet channel.

8. The sliding device with an oiler as described in claim 4, wherein, The first body has at least one latching part located on the side of the first body, and the mounting groove has a latching groove, so that the oil injector and the platform are fastened together by the latching part in the latching groove.

9. The sliding device with an oiler as described in claim 4, wherein, Each slider has an annular groove surrounding the oil inlet of the slider, and an O-ring disposed within the annular groove.

10. The sliding device with an oiler as described in claim 9, wherein, The lower surface of the first body has two limiting grooves for each of the O-rings to fit into.
