Abstract
The fit structure of cylinder block and port connection, including cylinder body, port connection, wherein, an annular groove is opened up in advance in cylinder interior, the drill-through oilhole in position being suitble on annular groove, oil-through hole position welding port connection is opened up on cylinder body guarantees that oil-through hole is communicated with port connection inner cavity, the groove width of the annular groove is greater than the diameter of oil-through hole, two bias transition of slot, the groove depth of the annular groove, which is no more than, survives internal diameter, the utility model is suitable for the oil cylinder of various head sides weldering port connection, structure is simple, it is easy to operate, the problem of can solve burr residual again, it is a kind of simple and practical structure, guarantee the out of roundness and machining accuracy of cylinder interior, promote cleaning inside degree.
Description
Technical field:
The utility model relates to technical field of hydraulic oil cylinder, are related to the fit structure of cylinder block and port connection, for
In the various cylinder bodies that need to weld hydraulic fluid port joint structure, cleaning inside degree is promoted.
Background technique:
In the various cylinder blocks that need to weld hydraulic fluid port joint structure, as shown in Figure 1, generally opening up hydraulic fluid port on cylinder body A
B welds port connection C positioned at the position of oil-through hole B, for the out of roundness and machining accuracy for guaranteeing cylinder interior, generally requires elder generation
Weld port connection, then finished inside diameter, last drill-through oilhole again.The fit structure of this cylinder block and port connection, in cylinder
The gap of body and port connection junction easily remains the burr that drilling generates, cleaning, and the means such as polishing can not effectively be gone
It removes.Burr is remained during cylinder efficient, cylinder body is entered easily under the drive repeatedly of high pressure oil, causes piston to block, can also
Sealing element is scratched, major accident is caused.
Summary of the invention:
The utility model aim is to overcome disadvantages mentioned above, provides that a kind of structure is simple, easy to operate cylinder block with
The fit structure of port connection guarantees the out of roundness and machining accuracy of cylinder interior, promotes cleaning inside degree.
To reach above-mentioned purpose, the utility model adopts the following technical solution:
The fit structure of cylinder block and port connection, including cylinder body, port connection, wherein opened in advance in cylinder interior
If an annular groove, the drill-through oilhole in position being suitble on annular groove opens up oil-through hole position welding port connection on cylinder body and guarantees
Oil-through hole is communicated with port connection inner cavity.
Further, the groove width of the annular groove is greater than the diameter of oil-through hole, two bias transition of slot.
Further, the groove depth of the annular groove, which is no more than, survives internal diameter.
By adopting the above technical scheme, the utility model is suitable for the oil cylinder of various head sides weldering port connection, and structure is simple,
It is easy to operate, and can solve the problem of burr remains, it is a kind of simple and practical structure, guarantees the true of cylinder interior
Circularity and machining accuracy promote cleaning inside degree.
Detailed description of the invention:
Attached drawing described herein is used to provide a further understanding of the present invention, and constitutes one of the utility model
Point, the exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the utility model
Improper restriction.In the accompanying drawings:
Fig. 1 is the utility model prior art construction schematic diagram；
Fig. 2 is the utility model structure diagram.
Specific embodiment:
In order to be clearer and more clear technical problem to be solved in the utility model, technical solution and beneficial effect, with
Under in conjunction with the accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein
Example is applied only to explain the utility model, is not used to limit the utility model.
As shown in Fig. 2, being the embodiments of the present invention, the fit structure of cylinder block and port connection, including cylinder body
1, port connection 2, wherein an annular groove 3 is opened up in advance in 1 inside of cylinder body, the drill-through oilhole 4 in position being suitble on annular groove 3,
4 position of oil-through hole welding port connection 2 is opened up on cylinder body 1 guarantees that oil-through hole is communicated with port connection inner cavity.
The groove width of the annular groove 3 is greater than the diameter of oil-through hole, two bias transition of slot.Groove depth, which is no more than, survives internal diameter.
In specific process, step 1: in cylinder interior oil-through hole position one of annular groove of vehicle, groove width ratio is excessively oily
The big 1mm in hole (unilateral 0.5mm), two bias are excessive.Groove depth, which is no more than, survives internal diameter.Step 2: drill-through oilhole, after polishing
Inside and outside burr is removed easily.Step 3: welding port connection.Step 4: finished inside diameter, since the evacuation position of annular groove is imitated
Fruit, blade and oil-through hole will not hit knife when finishing.
The utility model is suitable for the oil cylinder of various head sides weldering port connection, and structure is simple, easy to operate, and can be very well
Solve the problems, such as that burr remains, be a kind of simple and practical structure, guarantee the out of roundness and machining accuracy of cylinder interior, mention
Rise cleaning inside degree.
The preferred embodiment of the utility model has shown and described in above description, as previously described, it should be understood that this is practical new
Type is not limited to forms disclosed herein, and should not be regarded as an exclusion of other examples, and can be used for various other groups
Conjunction, modification and environment, and above-mentioned introduction or the technology of related fields can be passed through within the scope of the inventive concept described herein
Or knowledge is modified.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, then
It all should be in the protection scope of the appended claims for the utility model.
