Embodiment
In order to explain technological scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
Refer to Fig. 1 to Figure 6 shows that the graphic of the first preferred embodiment, the present invention is a kind of linear slide rail of tool lubricating structure, comprises:
One rail bar 1, it extends to strip structure along a direction, and defining this bearing of trend is axle direction X, and this rail bar 1 is provided with the sliding channel 11 of four axially X settings; One slide block 2, be sheathed on this rail bar 1, and be provided with the rolling groove 21 of this sliding channel 11 relatively, respectively this sliding channel 11 forms four load paths 90 with rolling groove 21, the present embodiment is with four load paths 90 for example, but more than two all can be applied technology of the present invention, and this slide block 2 is provided with four return ports 22, this return port 22 be arranged in parallel with this rolling groove 21 substantially, and arranging as non-parallel may for the error in processing; Two end cap 3, be arranged at the both ends of the surface of the axle direction X of this slide block 2 respectively, two these end caps 3 are respectively equipped with four backflow roads, this backflow road formed in the half backflow mutual assembly in road 311,321 of the present embodiment set by the body 31 of end cap 3 and cover plate 32, this backflow road is a U-shape, its two ends are connected this load path 90 and this return port 22 respectively, and two these backflow roads, a load path 90 and return port 22 form a circulating path, therefore have four circulating paths in the present embodiment; And this end cap 3 is provided with oil duct 33, one end of this oil duct 33 is connected with outside oil supplying device, and this oil supplying device provides below lubricant oil or lubricating grease to use lubricant oil to explain, and the opening 331 of the other end is adjacent to this load path 90 and arranges towards axle direction X; Multiple roll piece 7, it is arranged at respectively this circulating path; In the present embodiment, departing from rail bar 1 in order to allow those roll pieces 7 in slide block 2 can also be held on rolling groove 21, therefore be provided with three retainers in slide block 2, be respectively retainer 4, middle retainer 5 and lower retainer 6, need re-assembly again to avoid roll piece 7 to drop.
More than illustrate the present embodiment each element structure and between configuration, the enforcement aspect of lubricating structure of the present invention is below described:
Refer to shown in Fig. 3 to Fig. 6, the both sides of this slide block 2 are respectively equipped with the spaced rolling groove 21 of two row, between two these rolling grooves 21, there is an inner plane 23, in this, retainer 5 has a guiding face 51, a spacing is kept to arrange between this guiding face 51 and this inner plane 23, define between this inner plane 23 and this guiding face 51 is lubricant oil delivery section 80, this lubricant oil delivery section 80 is communicated with the opening 331 of this oil duct 33, when this opening 331 carries lubricant oil to this lubricant oil delivery section 80, lubricant oil can be fled along this lubricant oil delivery section 80, namely axially X flees, and gradually flee the load path 90 to both sides toward the Normal direction of axle direction X, respectively this roll piece 7 of load path 90 is positioned at lubrication.
Moreover, refer to Fig. 7 to Figure 9 shows that the graphic of the second preferred embodiment, the present embodiment is different from the first preferred embodiment to be: in this, the guiding face 51 of retainer 5 is fitted with this inner plane 23 and arranged, but because middle retainer 5 is plastic ejection moulding, be out of shape to some extent because of the longer relation of length unavoidably, therefore local may be had to fit completely but this part is not drawn and rung last lubrication effect, and the guiding face 51 of this retainer 5 is arranged with the shaft orientation flowing channel 511 of an axially X setting, this shaft orientation flowing channel 511 is connected with this opening 331, Normal direction separately in axle direction X is provided with multiple spaced lateral channel 512, this lateral channel 512 is communicated with this shaft orientation flowing channel 511, therefore this shaft orientation flowing channel 511 and lateral channel 512 form a lubricant oil delivery section 80 with this inner plane 23, when lubricant oil injects this shaft orientation flowing channel 511 by this opening 331, lubricant oil can gradually be fled toward lateral channel 512 again, lubricant oil to be delivered to respectively this roll piece 7 being positioned at load path 90, in addition, respectively the size of this lateral channel 512 can be difference, to control the lubricant oil oil pump capacity of each section, the structure of all the other elements, configuration and effect are identical with the first preferred embodiment, no longer to repeat at this more.
Finally, refer to Figure 10 to Figure 12 shows that the graphic of the 3rd preferred embodiment, the present embodiment is different from the first preferred embodiment to be: in this, the guiding face 51 of retainer 5 is a V-shaped structure, that is this guiding face 51 is made up of the plane that two have angle Q mutually, also can be the cambered surface formation that multiple plane mutually with angle forms or also can be arc-shaped, therefore keep a spacing to arrange between this guiding face 51 and this inner plane 23, because the design of guiding face 51 makes this spacing be of a size of gradual change, the size of each section of the project organization depending on guiding face 51 may have difference, and in this plane of the present embodiment two be symmetric design, therefore the size of the spacing of two these plane same positions is the same, and the guiding face 51 of this retainer 5 is arranged with the shaft orientation flowing channel 511 of an axially X setting, this shaft orientation flowing channel 511 is connected with this opening 331, this shaft orientation flowing channel 511 and guiding face 51 form a lubricant oil delivery section 80 with this inner plane 23, when lubricant oil injects this shaft orientation flowing channel 511 by this opening 331, lubricant oil can gradually be fled toward between guiding face 51 and inner plane 23 again, lubricant oil to be delivered to respectively this roll piece 7 being positioned at load path 90, subsidiary one carry be, in the present embodiment, because this guiding face 51 and inner plane 23 are less and gradually become large toward neutral position in the size of the spacing near opening 331 place, as shown in figure 12, such design main purpose to allow lubricant oil be uniformly distributed in load path 90, because larger the closer to the injection pressure of the lubricant oil of opening 331, therefore more closely spaced size can allow lubricant oil flee toward this spacing, and remaining lubricant oil is fled towards lubricant oil delivery section 80 intermediate portion again, make the acquisition lubricant oil that the load path 90 of intermediate portion can be real-time, the structure of all the other elements, configuration and effect are identical with the first preferred embodiment, no longer to repeat at this more.
Above-described embodiment and accompanying drawing non-limiting product form of the present invention and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present invention.
