Description
Technical field
This utility model relates to the fixture of a kind of plunger contouring for hydraulic inclined-axis motors, belongs to hydraulic motor zero
The clamp for machining technical field of part.
Background technology
Plunger is a strength member of hydraulic inclined-axis motors.As it is shown in figure 1, plunger 4 one end is provided with contouring 4-1, separately
One end is provided with outer conical surface 4-2.
The grinding technique being typically used in batch even high-volume hydraulic inclined-axis motors plunger at present is generally: double
Location, top formed grinding wheel, simultaneously the grinding conical surface and sphere, ensure the grinding of plunger.This just wants for lathe and emery wheel
Asking higher, from the point of view of small serial production, the equipment and the cost of charp tool that put into great number are not calculated.
Formed grinding wheel is for the inclined-axis motors plunger grinding of small serial production, and tool wear also can larger production
Production cost.
Utility model content
The technical problems to be solved in the utility model is in the grinding of hydraulic inclined-axis motors plunger, during small serial production such as
The cost of what reduction equipment.
In order to solve above-mentioned technical problem, the technical solution of the utility model is to provide a kind of for hydraulic inclined-axis motors
The fixture of plunger contouring, plunger at one end is provided with contouring, and the other end is provided with outer conical surface；It is characterized in that: fixture includes fixed
Position set, positioning sleeve is with being located in outside the outer conical surface of plunger, and positioning sleeve one end is located in pedestal, and the positioning sleeve other end is by lock
Jack panel is fixed with pedestal.
Preferably, it is provided with, inside described positioning sleeve, the taper hole that the outer conical surface with plunger matches, it is ensured that the location of plunger.
Preferably, described positioning sleeve is made up of two identical semicircle sets, in order to clamping and dismounting plunger.
Preferably, the cylindrical of described positioning sleeve matches with the endoporus of described pedestal, it is ensured that the position of positioning sleeve is accurate.
Preferably, the endoporus step surface that the end face with plunger matches it is provided with in described pedestal.
Preferably, the female thread of described locking nut matches with the external screw thread of pedestal.
By tightening locking nut so that the end face of plunger matches with the endoporus step surface of pedestal, thus ensures plunger
Accurate with the relative position of pedestal, it is ensured that the machining accuracy of plunger.
The device that this utility model provides overcomes the deficiencies in the prior art, simple in construction, low cost, and operation is quick, peace
Entirely, positioning precision is high, reliable and stable, is particularly suited for the grinding of the hydraulic inclined-axis motors plunger of small serial production.

Fig. 1 is the plunger schematic diagram of hydraulic inclined-axis motors；
The fixture schematic diagram of the plunger contouring for hydraulic inclined-axis motors that Fig. 2 provides for the present embodiment.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.Should be understood that these embodiments are merely to illustrate this
Utility model rather than limit scope of the present utility model.In addition, it is to be understood that reading the content that this utility model is lectured
Afterwards, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within this Shen equally
Please appended claims limited range.
The fixture schematic diagram of the plunger contouring for hydraulic inclined-axis motors that Fig. 2 provides for the present embodiment, described use
Fixture in the plunger contouring of hydraulic inclined-axis motors is made up of locking nut 1, positioning sleeve 2 and pedestal 3 etc..
Positioning sleeve 2 is made up of two identical semicircle sets, by entirety circle set from spaced intermediate, forms two identical semicircles
Set, in order to clamping and dismounting plunger 4.The internal taper hole being provided with of positioning sleeve 2 matches with outer conical surface 4-2 of plunger 4, it is ensured that post
The location of plug 4.
Plunger 4 is located in positioning sleeve 2, and positioning sleeve 2 one end is arranged in pedestal 3, and the cylindrical of positioning sleeve 2 is interior with pedestal 3
Hole matches, it is ensured that the position of positioning sleeve 2 is accurate.Pedestal 3 and plunger 4 junction are provided with endoporus step surface.Positioning sleeve 2 other end
Being fixed with pedestal 3 by locking nut 1, the female thread of locking nut 1 matches with the external screw thread on pedestal 3.Locking nut 1 is worn
Cross plunger 4.
By tightening locking nut 1 so that the end face of plunger 4 matches with the endoporus step surface of pedestal 3, thus ensures post
Plug 4 is accurate with the relative position of pedestal 3, it is ensured that the machining accuracy of plunger 4.
