Abstract
The utility model discloses oil cylinder axis pins, including pin body, limit base；Described limit base one end is great circle cambered surface, the other end is small arc surface, and the great circle cambered surface smoothly transits with small arc surface to be connect；The centrally disposed limiting through hole of small arc surface, the pin body are connect with limit base.The utility model effectively improves the reliability of axis pin connection, fastness, reduces the risk of connection, improves safety and reliability and service life that equipment uses；The costs of production and operation for effectively reducing enterprise improves the economic benefit of enterprise.
Description
Technical field
The utility model is related to oil cylinder accessories fields, more particularly to oil cylinder axis pin.
Background technology
Axis pin is the part being commonly used in the assembling process of parts.It was linked and packed in the parts of oil cylinder
Cheng Zhong, axis pin are also common connection limiting component.But axis pin used at present, the radial direction for being usually utilized in axis pin are set
Through-hole is set, limit fixation and limit to axis pin are being realized by through-hole.In use, there is connection in above-mentioned technical proposal
It is insecure, the technical problems such as reliability is low.
Utility model content
The technical problem to be solved by the present invention is to provide it is a kind of connection it is more secured, effectively improve connection reliability
Oil cylinder axis pin.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
Oil cylinder axis pin, including pin body, limit base；Described limit base one end is great circle cambered surface, the other end is small arc-shaped
Face, the great circle cambered surface smoothly transits with small arc surface to be connect；The centrally disposed limiting through hole of small arc surface, the axis pin sheet
Body is connect with limit base.
Preferably, the centrally disposed installation through-hole of the great circle cambered surface, the pin body pass through weldering after passing through installation through-hole
It connects and is welded to connect pin roll end face and great circle cambered surface.
Preferably, the pin body and the diameter of the interconnecting piece of installation through-hole minor diameter fit are less than pin body upper end
Diameter, the interconnecting piece stretch out the end face of limit base, are connect on the cylindrical surface of interconnecting piece with great circle cambered surface by welding.
Preferably, the pin body is integrally formed with limit base.
Using above-mentioned technical proposal, due to the use of technical characteristics such as pin body, limit bases.By being set on limit base
Limiting through hole is set, it is integral in use, by the limiting through hole on limit base by axis pin pin body to be connect with limit base
It is fixedly connected, effectively increases old fixed and connection the reliability of axis pin connection.
Description of the drawings
Fig. 1 is the utility model schematic front view；
Fig. 2 is the utility model schematic top plan view；
Fig. 3 is one pin body schematic front view of the utility model embodiment；
Fig. 4 is one limit base schematic front view of the utility model embodiment.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1 and Figure 2, oil cylinder axis pin, including pin body 1, limit base 2；2 one end of limit base is orthodrome
Face 3, the other end are small arc surface 4, and great circle cambered surface 3 smoothly transits with small arc surface 4 and connect in specific implementation；In small arc surface 4
Pin body 1 is connect by centrally disposed limiting through hole 5 with limit base 2.
Embodiment one：
As shown in attached drawing 3 and attached drawing 4, in 3 centrally disposed installation through-hole 6 of great circle cambered surface, pass through installation logical pin body 1
Pin roll end face and great circle cambered surface 3 are welded to connect by welding behind hole 6.The connection of pin body 1 and 6 minor diameter fit of installation through-hole
The diameter in portion 7 is less than the diameter of 1 upper end of pin body, and interconnecting piece 7 stretches out the end face of limit base 2, by welding interconnecting piece 7
Great circle cambered surface 3 connects more than cylindrical surface.
Embodiment two：
In order to further increase the intensity of axis pin, pin body 1 and limit base 2 are integrally formed in specific implementation.
Pin body 1 is passed through in specifically used and needs to connect parts, passing through limit base 2 by above-mentioned technical proposal
4 centrally disposed limiting through hole 5 of small arc surface limit base 2 is fixed.By effectively improve axis pin connection reliability, securely
Property, the risk of connection is reduced, safety and reliability and service life that equipment uses are improved.
The embodiment of the utility model is explained in detail above in association with attached drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the scope of protection of the utility model.
