Abstract
A kind of structure of bearing pin, it comprises a columned bearing pin main body, the limit, one end of this bearing pin main body is provided with the bevel edge with certain guiding function, the other end limit is provided with outer flange collar and forms a bearing pin head, this bearing pin head with define one between pin body and be vertically connected shoulder, the perpendicular joints between described bearing pin head and pin body be at least provided with one oblique in make in 60-120 tool withdrawal grooves of spending; Described tool withdrawal groove to translation in bearing pin head be formed one wide, be conducive to the valley gutter that lubricant oil stops; The contiguous sidewall being provided with bevel edge offers at least one horizontal pin-and-hole perpendicular to axle center to described pin body; It is simple, easy to process that it has structure, and the closely cooperating of bearing pin head right angle when can realize Assembly of the parts, can get rid of because chamfering burr does not go to the greatest extent and produce fit up gap, being conducive to the features such as lubrication wet goods stop.
Description
Technical field
The utility model relates to a kind of pin shaft structure for assisted mining machine, belong to the fixed block technical field of mechanical connection.
Background technique
Bearing pin is the fastening piece of a class standard, widely uses in shovel crawler and other crawler equipment.It mainly comprises a columned bearing pin main body, the limit, one end of this bearing pin main body is provided with the bevel edge with certain guiding function, the other end limit is provided with outer flange collar and forms a bearing pin head, this bearing pin head with define a shoulder be connected between pin body; At concrete processing bearing pin and when being made into finished product, can occur being connected chamfering circle in the reason of the right angle vertically crossed of pin body and bearing pin head because of machining tool, this bearing pin is used for Assembly of the parts, the right angle of bearing pin head will there is chamfering circle and produce the obstruction of fit on, the cooperation of compaction cannot be carried out.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provide a kind of structure simple, easy to process, when can realize Assembly of the parts, bearing pin head right angle closely cooperates, can get rid of because chamfering burr does not go to the greatest extent and produce fit up gap, being conducive to the structure of lubricating the bearing pin that wet goods stops.
The purpose of this utility model has been come by following technical solution, described pin shaft structure, it comprises a columned bearing pin main body, the limit, one end of this bearing pin main body is provided with the bevel edge with certain guiding function, the other end limit is provided with outer flange collar and forms a bearing pin head, this bearing pin head with define one between pin body and be vertically connected shoulder, the perpendicular joints that it is characterized in that between described bearing pin head and pin body be at least provided with one oblique in make in 60-120 tool withdrawal grooves of spending.
Described tool withdrawal groove to translation in bearing pin head be formed one wide, be conducive to the valley gutter that lubricant oil stops.
The contiguous sidewall being provided with bevel edge offers at least one horizontal pin-and-hole perpendicular to axle center to described pin body.
The utility model belongs to improvements over the prior art, it is simple, easy to process that it has structure, the closely cooperating of bearing pin head right angle when can realize Assembly of the parts, can get rid of because chamfering burr does not go to the greatest extent and produce fit up gap, being conducive to the features such as lubrication wet goods stop.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlargement structural representation in B portion in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: Fig. 1, shown in 2, the structure of bearing pin described in the utility model, it comprises a columned bearing pin main body 1, the limit, one end of this bearing pin main body 1 is provided with the bevel edge 2 with certain guiding function, the other end limit is provided with outer flange collar and forms a bearing pin head 3, define one between this bearing pin head 3 with pin body 1 and be vertically connected shoulder 4, perpendicular joints between described bearing pin head 3 and pin body 1 be at least provided with one oblique in make in 60-120 tool withdrawal grooves of spending 5, this tool withdrawal groove with 45 degree for the best.
The preferred technological scheme of the present invention is: described tool withdrawal groove 5 to translation in bearing pin head 3 be formed one wide, be conducive to the valley gutter 6 that lubricant oil stops.
The present invention also in described pin body 1, the contiguous sidewall being provided with bevel edge 2 offers at least one horizontal pin-and-hole 7 perpendicular to axle center.
