Abstract
The utility model provides a shaft lock device for a chain pin, belongs to the technical field of chains, and solves the problem that larger friction is generated after rotation between the conventional outer chain plate and pin shafts, and lastly, a certain gap is formed between each pin shaft and the chain plate. The shaft lock device for the chain pin comprises blocking plates, wherein each blocking plate corresponds to one pin shaft, a blocking groove is formed in each blocking plate, a limiting groove is formed in each pin shaft, each blocking plate is attached to an outer chain plate and is fastened with the outer chain plate, and when each blocking groove is correspondingly buckled in the limiting groove of the corresponding pin shaft, the rotation of the pin shaft can be stopped. According to the shaft lock device, the rotation of the pin shafts can be well limited, so that the pin shafts cannot rotate actively, thus the integral assembly precision is improved, and meanwhile, by adopting each pin shaft with a hollow structure, riveting molding on the other side is simpler, and the working efficiency and the quality of a finished product are greatly improved.
Description
Technical field
The utility model belongs to the axle lock device of chain technical field, particularly a kind of chain pin.
Background technique
In mechanical transmission fields, chaindriven application is very extensive, is characterized in not having elasticity sliding motion and skids, and can realize the between centers transmission of larger distance, and velocity ratio is very stable, and transmission efficiency is higher, and overload capacity is strong.Forming chaindriven critical piece is sprocket wheel and Transmitted chains, wherein Transmitted chains is formed by inner link, sleeve, roller, outer plate, bearing pin serial connection, traditional Transmitted chains is because bearing pin often rotates thereupon, therefore make the larger friction of generation between outer plate and bearing pin, between last bearing pin and carrier bar, produce certain gap, make bearing pin occur the situation of double swerve, but often between some special chain drives, need good precision, the bearing pin rocking can affect the normal running of machine.
Summary of the invention
The purpose of this utility model is for the excessive problem that rubs between existing above-mentioned chain hinge pin, has proposed a kind of pivoting friction that can eliminate as far as possible bearing pin, makes bearing pin location axle lock device more accurately.
The purpose of this utility model can realize by following technical proposal: a kind of axle lock device of chain pin, it is characterized in that, it comprises block board, the every corresponding bearing pin of block board, above-mentioned block board is provided with U-shaped screens groove, bearing pin is provided with restraining groove, and described block board is sticked and fixes on outer plate and with outer plate, and screens groove is buckled on bearing pin and prevents that bearing pin from rotating.
Inner link is with annular array, adjacent is connected by outer plate between inner link between two, between inner link and outer plate, be inserted with the bearing pin of connection, outer plate and inner link can relatively rotate, by after bearing pin locking, bearing pin be relative outer plate in stationary state, inner link is set on bearing pin, can realize the independent rotation of inner link, avoid the pivoting friction between bearing pin and outer plate.
In the axle lock device of above-mentioned a kind of chain pin, described restraining groove is opened in bearing pin outer side surface, perpendicular to bearing pin and Parallel Symmetric setting between two.
In the axle lock device of above-mentioned a kind of chain pin, described block board is bolted on outer plate.
In the axle lock device of above-mentioned a kind of chain pin, described bearing pin is hollow structure, is provided with for spacing riveting ring on the bearing pin of relative limit groove one end.The bearing pin one of hollow structure can be saved material, is easier to the end riveting of bearing pin simultaneously.
Compared with prior art, the rotation that this device can good spacing bearing pin, makes the bearing pin can active rotation, improved whole assembling validity, adopt the bearing pin of hollow structure to make the riveting moulding of opposite side more easy simultaneously, greatly increase work efficiency, and the quality of finished product.

Fig. 1 is the scheme of installation of the axle lock device of this chain pin.
Fig. 2 is the structural representation of the axle lock device of this chain pin.
Fig. 3 is block board structural representation.
In figure, 1, bearing pin; 2, restraining groove; 3, screens groove; 4, block board; 5, bolt; 6, inner link; 7, riveting ring; 8, outer plate.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Fig. 1～Fig. 2, chain comprises the inner link 6 of a plurality of annular array, between adjacent inner link between two 6, by outer plate 8, is connected, and is inserted with the bearing pin 1 of connection between inner link 6 and outer plate 8, bearing pin 1 is hollow structure, and described inner link 6 is set in bearing pin 1 and can rotates relative to bearing pin 1.The axle lock device of this chain pin is arranged between outer plate 8 and bearing pin 1, comprise block board 4, the every corresponding bearing pin 1 of block board 4, as shown in Figure 3, above-mentioned block board 4 is provided with U-shaped screens groove 3, and bearing pin 1 one end has riveting ring 7, and the other end is provided with restraining groove 2, described restraining groove 2 is opened in bearing pin 1 outer side surface, perpendicular to bearing pin 1 and Parallel Symmetric setting between two.
Block board 4 is sticked and by bolt 5, fixes on outer plate 8 and with outer plate 8, in being buckled in the restraining groove 2 of bearing pin 1, screens groove 3 correspondences can stop the rotation of bearing pin 1, described riveting ring 7 and block board 4 are simultaneously spacing by moving left and right of bearing pin 1, after above-mentioned bearing pin 1 is spacing, inner link 6 are rotated alone.
Should be appreciated that, in claims of the present utility model, specification, all " comprising ... " is all interpreted as open implication, and namely its implication is equal to " at least containing ... ", and should not be construed as enclosed implication, its implication should not be construed " only comprising ... ".
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
