Background technique
Cycloid hydraulic motor is a hydraulic pressure execution device commonly used of realizing liquid-function conversion.Flat porting cycloid hydraulic pressure motor is a class wherein.During work, after pressured fluid enters housing from liquid entering hole, enter the secondary expansion engagement chamber that forms of cycloidal-pin wheel, its volume is constantly enlarged, and liquid then refluxes from refluxing opening in the secondary contraction engagement chamber that forms of cycloidal-pin wheel simultaneously, meanwhile, thrust plate in the flow-distribution mechanism is also by the synchronous driven rotary of flow couple axle, the continuous switching connected state that goes round and begins again, the continuous flow of the duct valve body by thrust plate, make expansion engagement chamber with shrink the engagement chamber and constantly change; In this process, the rotor of cycloidal-pin wheel pair is expanded the engagement chamber and orders about rotation with the pressure difference of shrinking the engagement chamber, and this rotation is delivered to output shaft output by couple axle, thereby realizes that hydraulic pressure can be to the conversion of mechanical energy.
A kind of typical thrust plate as shown in Figure 1, its middle part be a splined hole, the upper-end surface circumference is regularly arranged petal groove (referring to Fig. 3), these petal grooves are respectively with the assignment hole of bottom---interior inclined hole is communicated with outer inclined hole.For a long time, thrust plate adopts the material all in one piece manufacturing all the time, and processing petal groove mills by numerical control when reaching the assignment hole that communicates with it always or machining center carries out precision cutting processing.Because petal groove and assignment hole quantity are many, and need the conversion station to process step by step, so its manufacturing efficiency is very low, manufacture cost is very high.
Summary of the invention
The objective of the invention is to: the problem that manufacturing efficiency is low, manufacture cost is high that exists according to above-mentioned thrust plate, by architecture advances, a kind of thrust plate of flat porting cycloid hydraulic pressure motor easy to process, easy to manufacture is proposed, provide its manufacture method simultaneously.Thereby significantly reduce manufacture cost, manufacturing efficiency is provided, for mass industrialized production lays the foundation.
In order to achieve the above object, technological scheme of the present invention is: the thrust plate of flat porting cycloid hydraulic pressure motor, the center is a splined hole, dark petal groove such as the circumferential arrangement that the upper-end surface splined hole is outer, described petal groove is communicated with the inclination assignment hole of bottom respectively, it is characterized in that: described thrust plate is formed by stacking by upper and lower disk body; Described upward disk body thickness equals the degree of depth of petal groove, is shaped on the described petal groove of circumferential arrangement; Described lower wall system has the inclination assignment hole corresponding respectively with each petal groove; The superposed surfaces soldering of described upper and lower amphidisc connects.
The present invention further improves, and described splined hole runs through described disk body down, and the described disk body center of going up is shaped on the center hole of diameter greater than the big footpath of described splined hole.
Its manufacture method may further comprise the steps:
1, go up the disk body blanking---obtain processing the required sheet material blank of disk body by the overall sizes blanking;
2, go up the disk body punching out---on last disk body blank, go out the petal slotted eye of circumferential arrangement with shaping die;
3, disk body under the processing---process down the disk body blank, draw out the center hole spline;
4, disk body seam up and down
4-1, superimposed---above-mentioned upper and lower disk body location is superimposed, and add brazing material;
4-2, heating---be warming up to the above temperature of brazing material fusing point gradually;
Solid 4-3, insulation---make the superposed surfaces place form solid-liquid-not homophase body, kept temperature 20-36 minute;
4-4, cooling---naturally cool to room temperature;
5, fine finishing---finish following process, form finished product.
More than further to improve be to go out the center hole of diameter greater than the big footpath of described splined hole in last disk body punching out simultaneously in the described step 2.
Be understood that the present invention has broken the traditional overall structure of thrust plate, thereby make the petal groove be adopted punch process to replace cutting, so work efficiency improves greatly, cost significantly reduces.Facts have proved that no matter dimensional accuracy, join strength, sealability all can satisfy the quality of product requirement.
