Embodiment
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment 1
By reference to the accompanying drawings, the oil-leakage-prevention pipeline (this peripheral milling is full-automatic numerical control peripheral milling espespecially) of a kind of peripheral milling of the present embodiment, comprise sleeve 1, housing 2, cover plate 3, emery wheel 4 and sliding bearing, it is inner that described housing 2 is arranged at sleeve 1, and the two ends of this housing 2 are by cover plate 3 reliable sealing.Described sliding bearing laterally runs through housing 2, and this sliding bearing comprises grinding wheel spindle 5 and bearing shell, and one end of grinding wheel spindle 5 is connected with the emery wheel 4 of high speed rotating.
The present embodiment adopts lubricant oil in rubber seal seal oil chamber for solving traditional peripheral milling, prevents the scheme of peripheral milling leakage of oil.Because rubber seal is easily aging, Sealing changed by machine of need frequently tearing open, grinds the problems such as internal components infringement is large to foreign round, is provided with oil-leakage-prevention pipeline in housing 2 inside.
Referring to Fig. 2, described oil-leakage-prevention pipeline comprises the first main oil circuit 61 and the second oil circuit 63, and wherein, the first main oil circuit 61 is embedded in the housing 2 on grinding wheel spindle 5 top, and the second oil circuit 63 is embedded in the housing 2 of grinding wheel spindle 5 bottom.First main oil circuit 61 and the second oil circuit 63 are separated by oil sealing 62, described oil sealing 62 comprises stage clip and copper ring, copper ring is placed on grinding wheel spindle 5, one end of stage clip is against cover plate 3, the other end is connected with copper ring, the housing 2 of the thrust that the pressured spring of copper ring provides and the first main oil circuit 61 both sides is fitted, and blocks the port of the first main oil circuit 61.Because copper ring has wear-resisting, that material is softer advantage, therefore copper ring well can be fitted with housing 2, thus ensure that the reliability of the first main oil circuit 61 and the second oil circuit 63 separated by oil sealing 62.
Referring to Fig. 1, the oil outlet 71 that described sleeve 1 outside sets gradually the main oil circuit 61 of oil outlet tube 81, oil inlet pipe 82 and return tube 83, first is from top to bottom opened in the highest point of the first main oil circuit 61, and this oil outlet 71 is connected with oil outlet tube 81.The filler opening (not shown) of the first main oil circuit 61 is then connected with oil inlet pipe 82.The return opening 72 of described second oil circuit 63 is opened in the lowest part of the second oil circuit 63, and this return opening 72 is connected with return tube 83.In the present embodiment, the caliber of oil outlet tube 81 is greater than the caliber of oil inlet pipe 82, and oil outlet tube 81, oil inlet pipe 82 are all connected with lubricating oil tank with return tube 83, are also provided with oil strainer between oil inlet pipe 82 and lubricating oil tank.
The present embodiment lubricant oil can realize zero negative-pressure cyclic circulation at oil-leakage-prevention channel interior, thus reaches lubrication object, and adopts this oil-leakage-prevention pipeline peripheral milling long-time running also to there will not be leakage of oil situation, and its principle is as follows:
Lubricant oil enters the main oil circuit 61 of the first main oil circuit 61, first through oil inlet pipe 82 and lubricant oil is delivered to the inner each lubricant housings of peripheral milling, thus reaches lubrication object.Lubricant oil is full of whole first main oil circuit 61 gradually, flow out finally by the oil outlet 71 being positioned at the first main oil circuit 61 highest point, caliber due to oil outlet tube 81 is greater than the caliber of oil inlet pipe 82, the fuel-displaced speed of lubricant oil is more than or equal to oil-feed speed, so lubricant oil can realize zero negative-pressure cyclic circulation in the first main oil circuit 61.Because though copper ring reliably can be fitted with housing 2, still have a small amount of lubricant oil to overflow, the present embodiment devises the second layer barrier of the second oil circuit 63 as sealing, the a small amount of lubricant oil overflowed from the first main oil circuit 61 leans on the physical flow characteristic of liquid to flow in the second oil circuit 63, flows out finally by return tube 83.Because the lubricant oil refluxed through oil outlet tube 81, return tube 83 carries impurity, again circulate so the lubricant oil in lubricating oil tank needs first to enter the first main oil circuit 61 again through oil strainer filtration.
The oil-leakage-prevention pipeline of a kind of peripheral milling described in embodiment 1, abandon the old scheme using rubber seal sealing, prevent leakage of oil, according to peripheral milling own structural characteristics, for peripheral milling devises brand-new oil-leakage-prevention pipeline, this oil-leakage-prevention pipeline structure simplicity of design makes the reforming cost of peripheral milling low, achieve lubricant oil zero negative-pressure cyclic lubrication in oil pocket simultaneously, and can long-time running safeguard without the need to tearing machine open, greatly reduce maintenance cost.
Schematically above be described the utility model and mode of execution thereof, this description does not have restricted, and also just one of the mode of execution of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the mode of structure similar to this technological scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
