The left end of separation disc connected unit is installed on separator.The utility model combination after, in ball basal plane equipment, by with sand
Wheel coordinates, and can effectively process the ball basal plane radius less than 90mm.
It is non-, it is necessary to repeatedly be processed during being processed using above-mentioned frock to the ball basal plane of taper roller
Normal trouble, processing are inconvenient.
The content of the invention
The technical problem to be solved in the present invention is to provide the taper roller ball that a kind of ball basal plane for facilitating taper roller is processed
Basal plane processing technology.
In order to solve the above technical problems, the technical scheme is that：A kind of machining technology for spherical fiducial surface of tapered roller, it is created
New point is：The processing technology comprises the steps：
a）Roller is installed：First, taper roller to be processed is positioned on special processing tool, the processing tool includes
One roller lays unit, and the roller, which lays unit, includes a roller placement rack, and the roller placement rack is in rectangular-shape, in roller
The upper end of placement rack has the V-shaped groove for holding taper roller and placing in a cross section, is also set on two inwalls of groove
Scuff-resistant coating is equipped with, taper roller is positioned in groove, and is rotated by motor driven；
b）The processing of ball basal plane prepares：Roller placement rack is pushed at grinding unit, the grinding unit is arranged on roller including one
The grinding knife tool of placement rack side, when roller placement rack moves, it is to be ensured that the center line of taper roller and the sword of grinding knife tool
Angle between face is between 30 ° -40 °, until the blade surface of the fitting grinding knife tool in end face to be processed of taper roller, is completed accurate
Standby work；
c）Ball basal plane is processed：Rotated by motor driven taper roller, while rotating, using grinding knife tool to taper roller
End face carries out grinding, and during grinding, the rotating speed of taper roller is in 1200r/min, until processing ball base
Untill face, the processing of spherical base surface of tapered roller is completed.
Further, in the step a, scuff-resistant coating is diamond abrasionproof backing plate.
The advantage of the invention is that：The machining technology for spherical fiducial surface of tapered roller of the present invention leads to during being processed
The angle crossed between the center line of control taper roller and the blade surface of grinding knife tool is between 30 ° -40 °, so as to time processing
Go out the whole ball basal plane of taper roller, without secondary operation, improve operating efficiency；Moreover, processing method as using so that
Taper roller is fixed without complicated structure, therefore need to can only be carried out using simple roller placement rack to place roller
Follow-up processing, it enormously simplify the complexity of whole frock so that processing also becomes convenient.
Diamond abrasionproof backing plate is used for scuff-resistant coating, using the wear-resisting characteristic of diamond itself, avoids and is rolled in circular cone
Son causes to wear during rotating to roller placement rack, improves its service life, and diamond abrasionproof backing plate can mass
Production, replacing are also convenient for.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the schematic diagram of the spherical base surface of tapered roller processing tool of the present invention.
Fig. 2 is the schematic diagram of the roller placement rack of the present invention.
Embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among described scope of embodiments.
As shown in Figure 1 and Figure 2, spherical base surface of tapered roller processing tool of the invention includes
One roller lays unit, and the roller, which lays unit, includes a roller placement rack 1, and schematic diagram as shown in Figure 2 is understood, the rolling
Sub- placement rack 1 is in rectangular-shape, what the appearance taper roller 4 for having a cross section V-shaped in the upper end of roller placement rack 1 was placed
