Abstract
A lubrication structure for a pin shaft hole of a tilting pivot rod of a roughing-up pusher tilting machine comprises a tilting hook, wherein the tilting hook is in shaft connection with a switching part of the tilting pivot rod through a pin shaft, the switching part is provided with a radial oil injection hole, a pair of stepped ring-shaped bearing bushes are arranged between the bearing bushes, and the oil storage ring is connected with the oil injection hole; an oil storage tank is arranged between the bearing bush and the pin shaft and is communicated with the oil storage ring; an elastic end cover is arranged at the end part of the oil filling hole, the elastic end cover comprises an outer end cover and an inner end cover, and a spring is arranged between the outer end cover and the inner end cover; the outer ring of the outer end cover is provided with threads and is screwed on the threads at the end part of the oil filling hole; the outer ring of the inner end cover is abutted against the inner wall of the oil filling hole. The invention has the advantages that: the lubricating oil is driven by pressure to flow along the surface of the pin shaft more easily; in addition, an oil storage ring is added, so that more lubricating oil can be conveniently stored to be communicated with the oil storage tank, and sufficient lubrication is ensured.
Description
Technical Field
The invention relates to the field of machinery, in particular to a sealing structure.
Background
The turning pivot rod of the roughing push lathe turning machine is connected with a turning hook system through a pin shaft to complete the turning of a steel billet, the lubrication adopted in the prior art is glycerol lubrication, an oil filling hole is formed in the pin shaft, and the glycerol enters the oil filling hole through the pin shaft (as shown in figure 2) and reaches an oil groove of a bearing bush of the turning pivot rod to complete the lubrication. But in the in-service use has some not enough, because the oil filler point of round pin axle is just 1, and it is inhomogeneous to get into the glycerine in tilting pin axle bush, and is lubricated not good, and the oil groove of tilting pin axle bush is too shallow simultaneously, causes the oil groove to have too little, and lubricated effect is not good, causes tilting pin axle hole wearing and tearing too big, and the tilting height is shut down inadequately.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a lubricating structure, an oil injection hole originally arranged on a pin shaft is changed into a steel turnover pivot rod by changing a lubricating mode, and meanwhile, the structure and the size inside the pin shaft hole of the steel turnover pivot rod are changed, so that the problem of poor lubrication in the original design is solved, and the specific technical scheme is as follows:
a lubrication structure for a pin shaft hole of a tilting pivot rod of a roughing-up pusher tilting machine comprises a tilting hook, wherein the tilting hook is in shaft connection with a switching part of the tilting pivot rod through a pin shaft, a bearing bush is sleeved outside the pin shaft, the switching part is provided with a radial oil filling hole, the bearing bush is in a pair of stepped rings, an oil storage ring is arranged between the bearing bushes, and the oil storage ring is connected with the oil filling hole; an oil storage tank is arranged between the bearing bush and the pin shaft and is communicated with the oil storage ring; an elastic end cover is arranged at the end part of the oil filling hole, the elastic end cover comprises an outer end cover and an inner end cover, and a spring is arranged between the outer end cover and the inner end cover; the outer ring of the outer end cover is provided with threads and is screwed on the threads at the end part of the oil filling hole; the outer ring of the inner end cover is abutted against the inner wall of the oil filling hole.
The axial distance between the bearing bushes is 18-20mm, and the width of the oil groove is 4.5-5 mm.
And a sealing ring is arranged on the outer side of the elastic end cover, and a locking nut is arranged outside the sealing ring.
The invention has the advantages that: because the radial oil filling hole and the elastic end cover structure are adopted, the pressurizing distance of the lubricating oil is shortened, and the pressure direction is vertical to the axial direction of the pin shaft, so that the lubricating oil is driven by the pressure to flow along the surface of the pin shaft more easily; in addition, an oil storage ring is added, so that more lubricating oil can be conveniently stored to be communicated with the oil storage tank, and sufficient lubrication is ensured.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural diagram of the prior art.
Detailed Description
The invention is specifically described below with reference to the accompanying drawings, and as shown in fig. 1, the invention comprises a tilting hook 1, wherein the tilting hook 1 is coupled with a switching part 21 of a tilting pivot rod 2 through a pin shaft 3, the pin shaft 3 is externally sleeved with a bearing bush 5, the switching part 21 is provided with a radial oil filling hole 4, the bearing bush 5 is in a pair of stepped rings, an oil storage ring 6 is arranged between the bearing bushes, and the oil storage ring 6 is connected with the oil filling hole 4; an oil storage tank 7 is arranged between the bearing bush 5 and the pin shaft 3, and the oil storage tank 7 is communicated with an oil storage ring 6; an elastic end cover is arranged at the end part of the oil injection hole 4, the elastic end cover comprises an outer end cover 8 and an inner end cover 10, and a spring 9 is arranged between the outer end cover 8 and the inner end cover 10; the outer ring of the outer end cover 8 is provided with threads and is screwed on the threads at the end part of the oil filling hole 4; the outer ring of the inner end cap 10 abuts against the inner wall of the oil filling hole 4 to prevent the lubricating oil from flowing into the spring region from the gap between the inner end cap and the oil filling hole, so that the inner end cap 10 is ensured to press the lubricating oil down along the oil filling hole under the action of the pre-tightening elastic force of the spring, and the lubricating oil moves towards the surface of the pin shaft under the action of the pressure.
Preferably, the axial distance between the bearing bushes is 18-20mm, and the width of the oil groove is 4.5-5 mm.
In order to ensure the sealing of the oil filling hole, a sealing ring is arranged on the outer side of the elastic end cover, and a locking nut is arranged outside the sealing ring, which is a common technology and is not shown in figure 1.
