Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
By Fig. 1 in conjunction with shown in Fig. 2,3; a kind of oil return apparatus of clamping mechanism; comprise bearing pin 1 and lining 2; described lining 2 is sheathed on bearing pin 1; described lining 2 is provided with fuel feed hole 21; on the inwall at described lining 2 two ends, be equipped with seal 22; described lining 2 inwalls are provided with multiple tracks and hold oil groove 23; described appearance oil groove 23 is corresponding with fuel feed hole 21; the footpath of described bearing pin 1 is upwards provided with the intercommunicating pore corresponding with holding oil groove 23 11; the axial direction of described bearing pin 1 is provided with the oil outlet 12 being connected with fuel tank, and described intercommunicating pore 11 is connected with oil outlet 12.The beneficial effects of the utility model are, on the inwall of lining, seal are set, and are convenient to lubricating oil to be locked in lining, and in lining, are provided with appearance oil groove, are convenient to set up oil film between lining and bearing pin, make the proper lubrication of product energy.On bearing pin, be provided with intercommunicating pore and tap, be convenient to the recovery of lubricating oil, avoid the waste of clamping mechanism or injection machine pollution and lubricating oil.Meanwhile, that the utility model also has is simple in structure, easy for installation, energy consumption is low, pollutes the advantages such as little.
Described lining 2 is outer is arranged with toggle link 3, and described toggle link 3 is provided with rationed hole 31, and described rationed hole 31 is corresponding with fuel feed hole 21.The outer wall of described lining 2 is provided with cannelure 24, and described fuel feed hole 21 is located in cannelure 24.Specifically, described fuel feed hole 21 is multiple, and fuel feed hole 21 is circumferentially distributed in cannelure 24.In particular, adjacent fuel feed hole 21 is equally spaced in cannelure 24.Specifically, described appearance oil groove 23 twist.In particular, described appearance oil groove helix at least comprise a right-handed screw and a backpitch.The oil-feed of being more convenient for of such structure, as long as squeeze in cannelure when the rationed hole oil-feed on toggle link, lubricating oil just can enter in lining reliably.Multiple tracks is held being arranged so that of oil groove and multiple fuel feed holes, has reduced the difficulty of processing of product, lubricating oil can be entered reliably and hold in oil groove.Certainly, what hold oil groove can be also the figure of eight, other shapes such as rectangle.
