Abstract
The utility model provides a mesopore platform truck claw arm round pin axle, including round pin axle body, adapter sleeve and fastening bolt, round pin axle body is the column, and its one end center department opens along the axial has the fastening bolt hole to through fastening bolt connection adapter sleeve, central the locating of the other end inwards is equipped with the grease nipple counter bore along the axial, has the butter hole and its radial division is still followed in the surface of round pin axle body, the butter hole is link up with the grease nipple counter bore mutually. The utility model discloses a fastening bolt connects the adapter sleeve, and the fastening of being convenient for prevents effectively that it is not hard up, the grease nipple is effectively avoided being hit absolutely inside being located round pin axle body completely, and has eliminated original vulnerable area, has made it can do not not cut off by the shearing force.
Description
Technical field
The utility model belongs to link field, is specifically related to the bearing pin that a kind of SIMBA of being applicable to series chassis pawl arm is connected with pawl arm oil cylinder and other this type.
Background technique
The pawl arm of mesopore chassis is connected by pawl arm bearing pin with pawl arm oil cylinder, and in running, pawl arm oil cylinder band pawl arm puts drill steel, and pawl arm bearing pin subjects larger shearing force.There is following problem in current pawl arm pin shaft structure:
1, the fastening round nut at pawl arm bearing pin two easily loosens, and due to structural limitation after loosening, fastening difficulty again;
2, on pawl arm bearing pin, the position of grease nipple is given prominence to after mounting, fragile during use, cannot continue to play oiling effect;
3, pawl arm bearing pin is comparatively weak, is easily cut off by shearing force effect.
Therefore, developing a kind of Novel claw arm bearing pin for above-mentioned three point problem is those skilled in the art institute urgent need to solve the problem.
Summary of the invention
For solving the problem, the utility model discloses a kind of mesopore chassis pawl arm bearing pin.
In order to achieve the above object, the utility model provides following technological scheme:
A kind of mesopore chassis pawl arm bearing pin, comprises pin body, adapter sleeve and clamping bolt; Pin body is column, and its center, one end has fastening bolt holes vertically, and connects adapter sleeve by clamping bolt, and the other end center is axially inwardly provided with grease nipple counterbore, and the surface of pin body also radially has butter hole; Butter hole and grease nipple counterbore connect.
As preferably, pin body is cylindric, and radius pin body being connected with one end of adapter sleeve reduces gradually, and matches with adapter sleeve.
As preferably, pin body has one end of grease nipple counterbore and adapter sleeve are all provided with prism-shaped protection block away from the side of pin body.
The utility model provides a kind of mesopore chassis pawl arm bearing pin, is made up of pin body, adapter sleeve and clamping bolt.
Pin body in the utility model is column, and the center at its two ends is respectively equipped with grease nipple counterbore vertically and is connected with adapter sleeve by clamping bolt; And the surface of pin body radially has the butter hole connected with grease nipple counterbore.The utility model, by arranging grease nipple counterbore, makes the grease nipple after installing to be in completely in grease nipple counterbore, prevents it from being severed; And by clamping bolt, pin body is connected with adapter sleeve, instead of original structure by fastening round nut, adapter sleeve being fixed on bearing pin two ends, eliminate the vulnerable area in whole pin body, avoid it be cut off by shearing force effect; And use clamping bolt to instead of original round nut, not easily occur to loosen, run more reliable and stable.
Pin body in the utility model is preferably cylindric, and the radius it being connected with one end of adapter sleeve reduces gradually, this setting not only makes pin body be easier to be connected with adapter sleeve, and can effectively avoid adapter sleeve too give prominence to relative to pin body and cause overall operation unstable.
And the utility model also pin body will have one end of grease nipple counterbore and the adapter sleeve side away from pin body and be all provided with the protection block of prism-shaped; make the utility model can stable operation between the protection block of two prism-shaped, improve global reliability.
Compared with prior art, beneficial effect is the utility model: (1) connects adapter sleeve by clamping bolt, is convenient to fastening, effectively prevents it from loosening; (2) grease nipple is positioned at pin body inside completely, effectively avoids being severed; (3) eliminate original vulnerable area, make it can not be sheared power and cut off.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model.
Reference numerals list: pin body 1, adapter sleeve 2, clamping bolt 3, fastening bolt holes 4, grease nipple counterbore 5, butter hole 6.
Embodiment
Below with reference to specific embodiment, the technological scheme that the utility model provides is described in detail, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
Be illustrated in figure 1 structural representation of the present utility model, the utility model is a kind of mesopore chassis pawl arm bearing pin, comprises pin body 1, adapter sleeve 2 and clamping bolt 3.
Pin body 1 is in cylindric, and its center, one end has fastening bolt holes 4 vertically, and connects adapter sleeve 2 by clamping bolt 3, and the other end center is axially inwardly provided with grease nipple counterbore 5; Radius pin body 1 being connected with one end of adapter sleeve 2 reduces gradually, and matches with adapter sleeve 2; And pin body 1 has one end of grease nipple counterbore 5 and adapter sleeve 2 are all provided with prism-shaped protection block away from the side of pin body 1.
The surface of pin body 1 also radially has butter hole 6; Butter hole 6 and grease nipple counterbore 5 connect.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model and non-limiting technological scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
