Abstract
The invention discloses a turning technology for a bearing bush part, and the turning technology can be used solving the technical problem disclosed in the following drawing. A mandrel (2) and a tensioning sleeve (5) are in close fit with each other and are formed into a sealed cavity by a small piston (3), a sealing ring (4) and a bolt (7). The cavity is filled with liquid plastic (6); a mandril (1) can push the small piston (3) to move in the mandrel (2); when the mandril (1) moves left, the elastic recovery of the liquid plastic (6) pushes the small piston (3) to move left; and the radial size of the tensioning sleeve (5) is recovered to loose a workpiece. The tensioning sleeve (5) is made of 40Cr, the wall thickness of the tensioning sleeve (5) is 3mm after tempering treatment, the external diameter of the tensioning sleeve (5) is the standard size of a drawing by virtue of the self machining of an assembled machine tool; during turning machining, the bearing bush part is installed on the mandrel (2) and the tensioning sleeve (5); the pressure of a hydraulic cylinder configured by the mandril is 1.2Mpa; and a machining tool is selected according to the configurations, such as the material, roughness requirement and the like of a machined part.
Description
Affiliated technical field
The present invention relates to the turning processing technology of the Vehicle Processing technology, particularly bearing shell class part of thin sleeve part.
Background technology
Thin walled cylinder body class part is because its wall thickness is thinner; But dimensional accuracy of products, Geometrical Tolerance Principle are also high especially; Particularly the size of bearing shell class part and other required precisions are all very high; This type of part also is easily-consumed products, and traditional turning process can not satisfy the instructions for use and the designing requirement of mass production.
Summary of the invention
The present invention provides a kind of new turning recruitment skill, uses such turning process can satisfy the dimensional accuracy of cylinder class parts such as mass production bearing shell and the requirement of form and position tolerance.
It is to adopt a kind of new fluidity expander anchor clamps and new processing technology that the present invention solves the technical method that its technical problem adopts.
The dimensional accuracy of turning processing that the invention has the beneficial effects as follows product under the condition of mass production is high, cylindricity and axiality all can satisfy design and operational requirement.
Description of drawings.
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing is the structure chart of the used anchor clamps of this turning process.
1. push rods, 2. axle, 3. valve piston, 4. sealing ring, 5. ringfeder, 6. liquid plastics, 7. bolt in the drawings.
The specific embodiment
As shown in the figure, axle (2) and ringfeder (5) closely cooperate, and form the cavity of a sealing through valve piston (3), sealing ring (4) and bolt (7); Inside cavity is filled with liquid plastics (6), and push rod (1) is connected on the hydraulic jack of lathe spindle, and push rod (1) can promote valve piston (3) and in axle (2), move; Valve piston (3) is when moving right, and the liquid plastics (6) in the extrusion chamber is to such an extent as to ringfeder (5) radial dilatation is come the tensioner workpiece to be processed, when push rod (1) when being moved to the left; The elastic recovery of liquid plastics (6); Promote valve piston (3) and move to left, ringfeder (5) radial dimension is replied, and unclamps workpiece.
Ringfeder (5) material is selected 40Cr for use; And through modifier treatment, its wall thickness adopts 3mm, and inner chamber is not more than 0.05mm with respect to beating of main shaft; Its external diameter is that assembling back lathe is from the dimension that is machined to drawing; Turning adds and man-hour bearing shell class part is mounted on axle (2) and the ringfeder (5) like this, and the pressure of the hydraulic cylinder of push rod configuration is at 1.2Mpa, and process tool is according to selection of configuration such as the material of part to be processed and roughness requirements.Dimensional accuracy through such product processed can reach requirement, and endoporus can clampedly not destroy yet.Superiority for this processes of bearing shell of the thin-walled that particularly is difficult to processing is more outstanding.
Claims (1)
1. the turning process of bearing shell class part is characterized in that ringfeder adopts modifier treatment, and the turning clamping pressure is at 1.2Mpa.
