Abstract
This utility model relates to the fixed structure of a kind of cylindrical pin, including crank ear mount, pressing plate, locking member and cylindrical pin, described cylindrical pin has square spindle nose and cylinder axis body, the axis hole run through for cylinder axis body is offered in described crank ear mount, and the end of this axis hole is shaped to square counterbore, described square spindle nose can be embedded just below in described square counterbore；Described pressing plate is arranged on outside the end face that square spindle nose exposes with fixed cylinder bearing pin.Cylindrical pin fixed structure of the present utility model, cylindrical pin reasonable stress, radial rotating or axial float will not occur, and fixing operation is simpler.
Description
Technical field
This utility model relates to the fixed structure of a kind of reliable cylindrical pin.
Background technology
In plant equipment Design and manufacturing process, it is often necessary to by using cylindrical pin transition to connect, allow two pieces split
Parts are connected to become a global facility, allow two monomer parts can individually complete certain action again simultaneously, with
This plays the allomeric function of equipment.Old-fashioned cylindrical pin fixed form is by opening a groove on bearing pin, passing through pressing plate
It is stuck in inside pin groove, then fixes pressing plate by bolt, be finally reached the purpose of fixed pin shaft.The straight pin of this fixed form
The following several point defects of axle existence:
When straight pin is installed, because bearing pin coordinates tension with installing hole, cause the draw-in groove on bearing pin cannot be with fixation clip
Bolt hole position alignment, it is impossible to smooth bolt, pressing plate fix.It addition, the fixing straight pin of this mode crosses conference because of stress
Produce rotation and produce longitudinally or axially play, it is impossible to meet equipment and run use requirement.
Utility model content
Technical problem to be solved in the utility model is to provide the cylindrical pin of a kind of improvement for above-mentioned prior art,
And the fixed structure mode of correspondence, simplify the fixing of cylindrical pin, allow fixed installation operability strengthen, it is simple to maintenance of equipment personnel
Maintenance change operation, the stress additionally improving bearing pin is allowed to meet the demand that equipment is properly functioning.
The technical scheme in the invention for solving the above technical problem is: the fixed structure of a kind of cylindrical pin, including
Crank ear mount, pressing plate, locking member and cylindrical pin, described cylindrical pin has square spindle nose and cylinder axis body, described crank ear
Offering the axis hole run through for cylinder axis body on seat, and the end of this axis hole is shaped to square counterbore, described square spindle nose can
It is embedded just below in described square counterbore；Described pressing plate is arranged on outside the end face that square spindle nose exposes with fixed cylinder bearing pin.
Preferably, described pressing plate is fixed in crank ear mount by locking member.
Compared with prior art, the utility model has the advantage of: provide a kind of fixing reliable cylindrical pin and fix
Structure, cylindrical pin reasonable stress, axially or radially play will not occur, and fixing operation is simpler.
Accompanying drawing explanation
Fig. 1 is the structural representation of cylindrical pin in this utility model embodiment；
Fig. 2 is the fixed structure schematic diagram of cylindrical pin in this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As illustrated in fig. 1 and 2, the cylindrical pin 4 in the present embodiment includes cylinder axis body 4.2 and square spindle nose 4.1, this cylinder
The fixed structure of bearing pin, including crank ear mount 1, pressing plate 2, locking member 3 and cylindrical pin 4, described crank ear mount 1 offers confession
The axis hole a that cylindrical pin cylinder axis body 4.2 runs through, and the end of this axis hole a is shaped to square counterbore b, square spindle nose 4.1 can
It is embedded just below in described square counterbore b.Described pressing plate 2 is to be fixed in crank ear mount 1 by locking member 3, the positive the other side of pressing plate 2
Type counterbore is so that pressing plate is tightly sticked outside the end face that square spindle nose 4.1 exposes to reach to be fixed on cylindrical pin crank ear
Purpose on seat.
Above-mentioned cylindrical pin fixed structure, cylindrical pin reasonable stress, radial rotating or axial float will not occur, and
Fixing operation is simpler.
In addition to the implementation, this utility model also includes other embodiments, all employing equivalents or equivalence
The technical scheme that substitute mode is formed, within all should falling into this utility model scope of the claims.
Claims (2)
1. the fixed structure of a cylindrical pin, it is characterised in that: include crank ear mount, pressing plate, locking member and cylindrical pin, institute
