Abstract
The utility model relates to a device for equal pressure liquid grinding and superfinishing a hydraulic motor plunger, which comprises a workpiece (3) and a grinding fluid (2), and is characterized byalso comprising a rotating shaft (1), a pressurizing piston (4) and a cylinder body (5), wherein the rotating shaft (1) is installed in a hole which is preset on the cylinder body (5), the workpiece(3) is connected to the rotating shaft (1), the pressurizing piston (4) is installed in the cylinder body (5), and the grinding fluid (2) is filled in the cylinder body. The device for equal pressureliquid grinding and superfinishing the hydraulic motor plunger enhances the surface finish of the workpiece to Ra 0.2-Ra 0.4 on the premise of not changing the original dimensional accuracy and form and position accuracy of the workpiece.
Description
Technical field
The utility model relates to a kind of lapping device, particularly a kind of device of isobaric hydro-abrasion microstoning hydraulic motor plunger.
Background technology
The fineness of designing requirement periphery and inner hole surface reaches Ra0.4, and Geometrical Tolerance Principle is higher, and the common process method is that externally disc and endoporus carry out grinding behind the finish turning.But because of twice clamping, make workpiece deformation very big, do not reach designing requirement.Another common method is to carry out polishing behind the finish turning, and general the employing shaken polishing, but finds in the practice, the piece surface of in polishing process, can damaging, and also fineness can only reach about Ra0.7.
Summary of the invention
Solve the above-mentioned technical problem that microstoning hydraulic motor plunger exists, and a kind of device of isobaric hydro-abrasion microstoning hydraulic motor plunger is provided.
For achieving the above object, the technical solution of the utility model is as follows:
The device of isobaric hydro-abrasion microstoning hydraulic motor plunger, comprise workpiece, lapping liquid is characterized in that, also comprises rotating shaft, pressurizing piston, cylinder body, rotating shaft are installed in the hole that cylinder body establishes in advance, and workpiece is connected on the rotating shaft, pressurizing piston is installed in the cylinder body, and lapping liquid is filled in the cylinder body.
Beneficial effect: the device of isobaric hydro-abrasion microstoning hydraulic motor plunger of the present utility model makes under the prerequisite that does not change the workpiece original size precision and the accuracy of form and position, and workpiece surface finish is brought up to Ra0.2-Ra0.4.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, the device of isobaric hydro-abrasion microstoning hydraulic motor plunger comprises workpiece 3, lapping liquid 2, it is characterized in that, also comprise rotating shaft 1, pressurizing piston 4, cylinder body 5, rotating shaft 1 is installed in the hole that cylinder body 5 establishes in advance, workpiece 3 is connected on the rotating shaft 1, and pressurizing piston 4 is installed in the cylinder body 5, and lapping liquid 2 is filled in the cylinder body.
Rotating shaft drives the workpiece rotation with the speed of 1500r/min, and workpiece is immersed in the lapping liquid, and lapping liquid is to have on the basis of the 600# emery grinding grease that factory produces at 60% Yangzhou Hanjiang milling tool, adds 20% kerosene and 20% lard and makes.The bottom promotes processing by hydraulic oil and presses piston to process, and makes the pressure in the cylinder body reach 100kg/cm
2Be generally 15-20min between processing is real.In process, entire equipment is in the environment of a normal temperature and pressure.
