Description
Technical Field
The utility model relates to a steel sheet round pin axle with rich type lubricant groove belongs to the auto-parts field, the oiling pipe and the lubricant groove of in particular to steel sheet round pin.
Background
And the steel plate pin shaft is used for positioning the pin shaft of the automobile steel plate spring. The enterprise of current production heavily block steel sheet round pin axle, when processing heavily block steel sheet round pin axle, because heavily block steel sheet width broad, the length of steel sheet round pin axle > 170mm, and the oil filler point at center all need bore the degree of depth > 90mm basically, and the diameter of the fluted drill who uses must > 9mm can reach the intensity of the deep hole of bore the degree of depth > 90mm, and the oil filler point of major diameter can seriously reduce steel sheet round pin axle self intensity, current steel sheet round pin axle fuel feeding tank all is the style of calligraphy moreover, the friction position between the less and the steel sheet round pin axle of the shake range of steel plate spring when heavily blocking the full load goods only has the top, and the fuel feeding tank of style of calligraphy can't satisfy on a large scale lubrication, lead to the top of steel sheet round pin axle to abrade very fast, the condition of fracture occasionally takes place for the worn steel sheet round pin axle, the final accident. Therefore, a steel plate pin shaft with a thin oil injection hole and a large oil supply range of an oil supply groove is needed to replace the existing steel plate pin shaft of the straight-line-shaped oil supply groove.
Disclosure of Invention
The utility model relates to a steel sheet round pin axle with rich type lubrication groove has solved above-mentioned defect, adopt columniform round pin axle, below round pin axle the right sets up semicircular constant head tank, respectively set up a rectangular adjustment tank on the upper and lower of round pin axle the right top, the central authorities of round pin axle right flank have set up the circular shape oil filler point towards the upper left side, conical grease nipple has been installed on the top on oil filler point the right, the central authorities of selling epaxial side have transversely set up rich type's oil feed tank, the top on oil feed tank the right is connected with the left side of oil filler point, when steel sheet round pin axle needs the oiling, the butter gets into the oil filler point through the grease nipple, again through the oil filler point flow direction oil feed tank, then through six branches flow to the steel sheet round pin axle of oil feed tank above, make the steel sheet round pin axle above obtain abundant lubrication.
A steel plate pin shaft with a rich lubricating oil groove is characterized by comprising a pin shaft, a positioning groove, an adjusting groove, an oil filling hole, an oil outlet, an oil supply groove and a grease nipple;
the pin shaft is cylindrical, a semicircular positioning groove is formed below the right side of the pin shaft, a rectangular adjusting groove is longitudinally formed above and below the top end of the right side of the pin shaft, an oil filling hole with the diameter smaller than 5mm is obliquely formed in the center of the top end of the right side of the pin shaft towards the left upper side, an oil outlet in the top end of the left side of the oil filling hole extends to the upper side of the center of the right side of the pin shaft and is an oval groove, a Chinese character feng-shaped oil supply groove is transversely formed in the center of the upper side of the pin shaft, and the top end of the right side of the oil supply groove is connected with the oil outlet;
the grease nipple is conical and is arranged on the right side of the grease hole through threads.
Furthermore, the front parts of the three semicircular grooves longitudinally arranged at the front and the rear of the oil supply groove are all inclined towards the left, the rear parts of the three semicircular grooves are all inclined towards the left, and the inclination angle is larger than 40 degrees.
Has the advantages that: the enterprise of current production heavily block steel sheet round pin axle, when processing heavily block steel sheet round pin axle, because heavily block steel sheet width broad, the length of steel sheet round pin axle > 170mm, and the oil filler point at center all need bore the degree of depth > 90mm basically, and the diameter of the fluted drill who uses must > 9mm can reach the intensity of the deep hole of bore the degree of depth > 90mm, and the oil filler point of major diameter can seriously reduce steel sheet round pin axle self intensity, current steel sheet round pin axle fuel feeding tank all is the style of calligraphy moreover, the friction position between the less and the steel sheet round pin axle of the shake range of steel plate spring when heavily blocking the full load goods only has the top, and the fuel feeding tank of style of calligraphy can't satisfy on a large scale lubrication, lead to the top of steel sheet round pin axle to abrade very fast, the condition of fracture occasionally takes place for the worn steel sheet round pin axle, the final accident. When the steel plate pin shaft needs oil injection, butter enters the oil injection hole through the grease nipple, flows to the oil supply groove through the oil injection hole, flows to the upper surface of the steel plate pin shaft through six branches of the oil supply groove, and fully lubricates the upper surface of the steel plate pin shaft.
Drawings
FIG. 1 is a schematic structural diagram of a steel plate pin shaft with a rich lubricating oil groove;
the marks in the above figures are a pin shaft 1, a positioning groove 2, an adjusting groove 3, an oil filling hole 4, an oil outlet 5, an oil supply groove 6 and a grease nipple 7.
Detailed Description
The shape and structure of the present invention will be described in detail with reference to the accompanying drawings and the reference numerals:
a steel plate pin shaft with a rich lubricating oil groove is characterized by comprising a pin shaft 1, a positioning groove 2, an adjusting groove 3, an oil filling hole 4, an oil outlet 5, an oil supply groove 6 and a grease nipple 7;
the pin shaft 1 is cylindrical, a semicircular positioning groove 2 is arranged below the right side of the pin shaft, a rectangular adjusting groove 3 is longitudinally arranged above and below the top end of the right side of the pin shaft, an oil filling hole 4 with the diameter smaller than 5mm is obliquely arranged above the center of the top end of the right side of the pin shaft to the left, an oil outlet 5 at the top end of the left side of the oil filling hole 4 extends to the upper part of the center of the right side of the pin shaft 1 and is an oval groove, a Chinese character feng-shaped oil supply groove 6 is transversely arranged in the center above the pin shaft 1, and the top end of the right side of the oil supply groove 6 is connected with the oil outlet 5;
the grease nipple 7 is conical and is arranged on the right side of the grease hole 4 through threads.
Furthermore, the front parts of the three semicircular grooves longitudinally arranged in the front and the back of the oil supply groove 6 are all inclined towards the left, the back parts of the three semicircular grooves are all inclined towards the left, and the inclination angle is larger than 40 degrees.
When the steel plate pin shaft with the rich lubricating oil groove is used, a worker injects butter into a butter nozzle of the steel plate pin shaft by using a butter gun, the butter flows to the oil supply groove through the oil injection hole and then flows to the upper surface of the steel plate pin shaft through the six branch grooves of the oil supply groove, so that the upper surface of the steel plate pin shaft is fully covered with an oil film, and the friction between the hanging ring of the steel plate spring and the steel plate pin shaft when heavy-duty goods are clamped is fully lubricated, and the abrasion and fracture conditions are reduced.
The above-mentioned non-detailed description is prior art.
The foregoing is merely a general disclosure of the invention and is not intended to limit the invention in any way; those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the scope of the invention as defined by the appended claims.
