Abstract
The utility model discloses a grinding clamper of a slipper of an inclined disk type plunger pump, comprising a working disk and a clamper handle, wherein a lower end of the clamper handle is coaxially connected with an upper end of the working disk, a working hole set is arranged on the working disk, a plurality of working holes are radially uniformly distributed on the working disk, the diameter of the working hole is larger than the diameter of the head part of the slipper and smaller than the diameter of the bottom of the slipper; the radius of the clamp handle is set as R, the radius of the working hole is set as r, the distance between the centers of the working hole and the working disk is set as L, the relationship satisfies the following formula: L>R+r. The slipper in one plunger pump can be placed into one working hole set to be grinded, so as to increase the grinding working efficiency and the flatness difference between the slippers of one plunger pump is small to ensure the quality of the plunger pump.
Description
Technical field
The utility model relates to a kind of anchor clamps of machining, and the grinding clamp of the piston shoes of a kind of swash plate plunger pump of more specifically saying so belongs to the Machining Technology field.
Background technology
The swash plate plunger pump that on hydraulic crawler excavator, uses through the rotation of cylinder body, drives the rotation of each plunger that is arranged on the cylinder body axial direction, is provided with piston shoes in plunger end; Piston shoes comprise head and bottom, during the head of piston shoes ball-and-socket are arranged, and are connected with the bulb ball pivot of plunger; The bottom of piston shoes is a plane, and this plane is tight against on swash plate, through piston shoes moving at swash plate; Make plunger that axial reciprocating motion take place, realize the plunger displacement pump oil suction and press oil, for hydraulic crawler excavator provides power.
Can find out that in above-mentioned introduction the planarization of piston shoes bottom is crucial to the work of whole swash plate plunger pump.For this reason, in the manufacture process of swash plate plunger pump, need carry out milled processed to the piston shoes bottom.Existing to very simple to the anchor clamps of piston shoes bottom grinding; Be merely a cylinder object; The internal diameter of cylinder is greater than the head of piston shoes, less than the bottom of piston shoes; The head of piston shoes and the plunger that is connected pass the hole of cylinder like this, and the head of piston shoes is stayed the original end in hole of cylinder, the bottom of piston shoes is placed on the abrasive disk down grinds like this.The grinding clamp of the piston shoes of said structure can only grind piston shoes, on the one hand, and its inefficiency; On the other hand, owing in a plunger displacement pump several plungers are arranged, just have several piston shoes; The quantity of plunger and piston shoes is generally nine; Piston shoes are carried out single grinding, cause the poor flatness opposite sex of several piston shoes of a plunger displacement pump bigger easily, influence the quality of plunger displacement pump.
The utility model content
To above-mentioned situation, the problem that the utility model quasi-solution is determined provides a kind of its high efficiency, and the grinding clamp of the piston shoes of the swash plate plunger pump that the poor flatness opposite sex of several piston shoes of a plunger displacement pump is little is to guarantee the quality of plunger displacement pump.
For achieving the above object; The utility model adopts following technical scheme: a kind of grinding clamp of piston shoes of swash plate plunger pump; It comprises scratch diskette and chuck arbor, and the lower end of said chuck arbor links to each other with the upper end of scratch diskette is coaxial, and said scratch diskette is provided with the working hole group; Said working hole group is at same radially equally distributed several working holes of scratch diskette, and the diameter of said working hole is greater than the diameter of the head of piston shoes, less than the diameter of the bottom of piston shoes; The radius of setting said chuck arbor is R, and the radius of said working hole is r, and said working hole center is L to the distance at scratch diskette center, then satisfies L＞R+r.
Working hole group on the said scratch diskette is a group or more.The working hole quantity of working hole group is nine.The upper end of said chuck arbor also is connected with balancing frame.
Adopt said structure, the grinding clamp of the piston shoes of the swash plate plunger pump of the utility model is because scratch diskette is provided with the working hole group; And the working hole group has several working holes, therefore, the assembly of piston shoes and plunger can be installed in each working hole; Just can grind the bottom of a plurality of piston shoes simultaneously, in general the working hole quantity of a working hole group equates with the interior piston shoes quantity of a plunger displacement pump, like this; The piston shoes that plunger displacement pump is interior can be put and prevent grinding into a working hole group, have not only improved the high efficiency of grinding; And the poor flatness opposite sex of several piston shoes of a plunger displacement pump is little, has guaranteed the quality of plunger displacement pump.If one group of above working hole group is arranged on the scratch diskette, then can grind all piston shoes of more than one plunger displacement pump simultaneously.
Description of drawings
Fig. 1 is the structural representation of grinding clamp of the piston shoes of the utility model swash plate plunger pump;
Fig. 2 is the structural representation of scratch diskette end face.
Among the figure: 1-scratch diskette, 2-chuck arbor, 3-working hole, the head of 4-piston shoes, the bottom of 5-piston shoes, 6-balancing frame, 7-plunger.
The specific embodiment
Fig. 1, shown in Figure 2, the grinding clamp of the piston shoes of the swash plate plunger pump of the utility model, it comprises scratch diskette 1 and chuck arbor 2, the lower end of said chuck arbor 2 links to each other with the upper end of scratch diskette 1 is coaxial.
Said scratch diskette 1 is provided with the working hole group, and the working hole group on the said scratch diskette 1 is a group or more.A said working hole group is that working hole 3 quantity of said working hole group are nine at scratch diskette 1 same radially equally distributed several working holes 3.The radius of setting said chuck arbor 2 is R, and said working hole 3 radiuses are r, and said working hole 3 centers are L to the distance at scratch diskette 1 center, then satisfy L＞R+r.
The diameter of said working hole 3 is greater than the diameter of the head 4 of piston shoes, less than the diameter of the bottom 5 of piston shoes.The head 4 of piston shoes and the plunger 7 that is connected pass working hole 3 like this, and the head 4 of said piston shoes is stayed the original end of working hole 3.
The upper end of said chuck arbor 2 also is connected with balancing frame 6.
