Abstract
The invention discloses a special-shaped pin shaft chain machining device. The device comprises a chain plate structure, a connecting pin shaft and a roller; the chain plate structure is fixedly connected to the outer side of the connecting pin shaft, and includes an outer chain plate structure and an inner chain plate structure; the inner chain plate structure is positioned on the inner side of the outer chain plate structure; the outer chain plate structure is connected to the connecting pin shaft; the outer chain plate structure includes an upper outer chain plate, and a lower outer chain plate positioned on the lower side of the upper outer chain plate; the inner chain plate structure includes an upper inner chain plate, and a lower inner chain plate positioned on the lower side of the upper inner chain plate; the roller is positioned between the upper inner chain plate and the lower inner chain plate, and is fixed on the outer side of the connecting pin shaft; a sleeve is arranged between the roller and the connecting pin shaft; and the sleeve is tightly bonded on the outer side of the connecting pin shaft. After two ends of the pin shaft are machined as steps, the step pin shaft limits a downward pressing distance of an oil press in assembly of the outer chain plate, so that the chain tightening condition caused by lower outer section is prevented.
Description
Technical field
The present invention relates to chain manufacture field, a kind of special-shaped bearing pin chain processing unit (plant) and its method are particularly related to.
Background technology
The making form of bearing pin is varied in chain makes process, and traditional bearing pin manufacture is cylinder
Body, the infinite place when bearing pin of cylinder can be such that outer plate is connected with bearing pin, situations such as easily there is chain tight mesh, in order to avoid chain
When assembling because hydraulic press depression distance excessively caused by the tight mesh problem of chain, be that we devise a kind of new bearing pin side this
Formula is special-shaped bearing pin, a kind of device and processing method for special-shaped bearing pin R ＆ D design, and bearing pin two ends are processed into step
The depression distance of outer plate is then defined during formula during group is vertical, you can to avoid causing the tight mesh situation of chain.
The content of the invention
In view of the foregoing, the invention provides a kind of special-shaped bearing pin chain processing unit (plant) and its method.
To reach above-mentioned purpose, the technical solution adopted for the present invention to solve the technical problems is：
A kind of special-shaped bearing pin chain processing unit (plant), including link plate structure, connection bearing pin and roller；Described link plate structure is fixed
It is connected to the outside of described connection bearing pin；Described link plate structure includes outer plate structure and inner plate structure, inner plate knot
Structure is located at the inner side of outer plate structure；Described outer plate structure is connected on connection bearing pin；Described outer plate structure includes
Upper outer plate and the lower outer plate on the downside of upper outer plate；Described inner plate structure includes upper inner plate and positioned at upper
Lower inner plate on the downside of inner plate；Described roller is located between upper inner plate and lower inner plate, is fixed on described connecting pin
The outside of axle；Sleeve is additionally provided between described roller and connection bearing pin, sleeve is close to the outside of connection bearing pin.
Its feature further is as follows：
Described connection bearing pin is step bearing pin.
The invention provides a kind of method of special-shaped bearing pin chain processing unit (plant) is made, comprise the following steps：
（1）Step is processed at the two ends of bearing pin first, step bearing pin is made；
（2）Then by step（1）The step bearing pin for processing is arranged in inner plate structure, by inner plate structure, roller
And the mutual cooperation of sleeve, step bearing pin is connected and cooperates with outer plate structure；
（3）Pressing action is finally carried out with the external link plate structure of hydraulic press, complete special-shaped bearing pin by repeating action above
Chain.
Due to the utilization of above-mentioned technical proposal, after step is processed into bearing pin two ends by the present invention compared with prior art, platform
Rank bearing pin defines the depression distance of outer plate hydraulic press when assembling, and can thus avoid chain occur because acromere is relatively low
Tight purpose situation.
