Background technology
Pluger type hydraulic pump is an important device of hydraulic system, and it is hydraulic pump inspiration by oil distribution casing with oil
The low pressure oil gone is transformed into the output of hydraulic oil oil duct by oil distribution casing with oil.The hydraulic oil meeting sucked via oil distribution casing, discharged
Strong active force is produced on oil distribution casing, if taking no action to the fixed generation play that would be possible to causes the performance of hydraulic pump
Decline.
Existing pluger type hydraulic pump mainly strictly controls the design size and tolerance of oil distribution casing according to static balance, still
The processing cost of oil distribution casing will so be greatly increased, it is therefore necessary to develop a kind of performance that not only can guarantee that hydraulic pump, simultaneously
The technical scheme of the difficulty of processing of hydraulic pump oil distribution casing can be reduced.
Utility model content
The purpose of this utility model is to provide a kind of stabilization fixed structure of hydraulic pump oil distribution casing solve now with effective
There is the weak point of technology.
To reach above-mentioned purpose, the utility model adopts the following technical scheme that：
The stabilization fixed structure of hydraulic pump oil distribution casing, for stationary hydraulic pump oil distribution casing, the hydraulic pump oil distribution casing
Surface is provided with high pressure hydraulic fluid port and low pressure hydraulic fluid port；The surface of hydraulic pump oil distribution casing is divided into by the first installation by a middle separated time
Face and the second mounting surface, wherein, the high pressure hydraulic fluid port is located at the first mounting surface, and the low pressure hydraulic fluid port is located at the second mounting surface；And
Including：2-3 the first fixing screws, wait angle to be arranged on the periphery of first mounting surface, and the 2-3 first is fixed spiral shell
The installation position of nail is with the central point on hydraulic pump oil distribution casing surface apart from equal；With 2 the second fixing screws, described second is arranged in
On the periphery of mounting surface, and the central point on the installation position of 2 second fixing screws and hydraulic pump oil distribution casing surface is apart from equal,
And each second fixing screws installation position and hydraulic pump oil distribution casing surface central point line and middle separated time between angle
To be less than 45 degree more than 0 degree.
Opened up preferably, the surface of the hydraulic pump oil distribution casing corresponds to each first fixing screws and the second fixing screws
There is screw hole.
Preferably, the axis of all screw holes is equal with the central point distance on hydraulic pump oil distribution casing surface.
Preferably, the screw hole is countersunk screw hole.
Preferably, the quantity of first fixing screws is 2, the installation position of each first fixing screws and hydraulic pump
Angle between the line and middle separated time of the central point on oil distribution casing surface is 45 degree.
The utility model can effectively fix the position of oil distribution casing so that oil distribution casing is working by using said structure
When will not produce shake, reduce the operating noise of hydraulic pump；Moreover, also reduce the difficult processing of hydraulic pump oil distribution casing
Degree.

In figure：
1-hydraulic pump oil distribution casing；11-high pressure hydraulic fluid port；12-low pressure hydraulic fluid port；13-the first mounting surface；14-the second installation
Face；15-screw hole；2-the first fixing screws；3-the second fixing screws；4-middle separated time.
The utility model is described in further detail in conjunction with drawings and examples.
Embodiment
As depicted in figs. 1 and 2, the stabilization fixed structure of hydraulic pump oil distribution casing described in the utility model, mainly includes
There are 1,2 the first fixing screws 2 of hydraulic pump oil distribution casing and 2 the second fixing screws 3.
The surface of described hydraulic pump oil distribution casing is provided with high pressure hydraulic fluid port 11 and low pressure hydraulic fluid port 12.Pass through a middle separated time 4
The surface of hydraulic pump oil distribution casing is divided into the first mounting surface 13 and the second mounting surface 14, two mounting surfaces are semicircle face.
Wherein, the high pressure hydraulic fluid port 11 is located at the first mounting surface 13, and the low pressure hydraulic fluid port 12 is located at the second mounting surface 14.In the first installation
Two screw holes 15 are offered on the periphery in face, two screw holes 15 have also been opened up on the periphery of the second mounting surface, this four
The axis of screw hole 15 is equal with the central point distance on hydraulic pump oil distribution casing surface, that is, falls on hydraulic pump oil distribution casing surface
On same circumference.Four screw holes 15 are countersunk screw hole.
2 described the first fixing screws 2 are arranged in a screw hole 15 on the first mounting surface 13 respectively, and each
Angle α between the line and middle separated time 4 of the installation position of first fixing screws 2 and the central point on hydraulic pump oil distribution casing surface is 45
Degree.
2 second fixing screws 3 are arranged in a screw hole 15 of the second mounting surface 14 respectively, and each first
Angle β between the line and middle separated time 4 of the installation position of fixing screws 2 and the central point on hydraulic pump oil distribution casing surface is 0 degree<β<
45 degree.
Because the high pressure hydraulic fluid port on the first mounting surface of the present utility model is evenly distributed, stressing conditions are also relatively uniform, institute
Installed with two the first fixing screws using even distribution pattern.And the low pressure hydraulic fluid port on the second mounting surface, it is corresponding with oil
Disc thickness is that centre is most thin, gradually thickeied to both sides, therefore two the second fixing screws are used in both sides close to the position of middle separated time
Put installation.
The utility model mainly according to the work stressing conditions of oil distribution casing, reasonably arranges four fixing glues, effectively
Secure the position of oil distribution casing so that oil distribution casing is fixed when work, and effective stabilization, the work for reducing hydraulic pump is made an uproar
Sound.
