Abstract
Disclosed is a locking method of a ball connector. A locking tool of the ball connector is mounted on the working table (7) of a drilling press, the concave connecting shaft (1) a workpiece to be processed is mounted on the main shaft of the drilling press and meanwhile is concentric with an R-surface roller (5) of the locking tool of the ball connector, and the convex rotation shaft (2) of the workpiece to be processed is mounted inside the R-surface roller (5) of the locking tool of the ball connector and presses the rotating main shaft of the drilling press downwards. Under the pressure, the R of the R-surface roller (5) abrades the convex rotation shaft (2) of the workpiece to be processed and rotates, when the rotating main shaft of the drilling press continues to move downwards, the concave connection shaft (1) of the workpiece to be processed deforms along the R of the R-surface roller (5) under the action of extrusion force, and further SR locking can be gradually achieved. The locking method of the ball connector can guarantee stable dimension and achieve high efficiency.
Description
Technical field
The present invention relates to ball adapter, particularly a kind of locking method of ball adapter.
Background technology
In machine-building, the connection of some workpiece, because of structure specific (special) requirements, need connect by the mode of spherical locking, and this connected mode is to realize by the locking as shown in Figure 1 of spherical coupling assembling.Single roller that has that conventional method is conventional pushes, the method is that workpiece is fixed on lathe chuck, the cold deformation that is contained in the recessed connecting axle a of workpiece shown in roller on small tool extruding Fig. 1 by radial feed reaches and the connecting of workpiece protruding rotating shaft b spheroid, because the method is single roller extruding, by operator, controlling small tool radial feeds realizes, size repeatable accuracy is low, the size of the recessed connecting axle SR of workpiece is unstable, therefore cannot guarantee the unstability that packs tightly of the connection gap t of ball-and-socket and the protruding rotating shaft b of workpiece spheroid in the recessed connecting axle a of the workpiece shown in Fig. 1 and ball adapter.What the recessed connecting axle a of workpiece shown in Fig. 1 was subject in the process of single roller crimp is single radial load, and recessed connecting axle a is yielding for workpiece, and particularly, when the neck of the recessed connecting axle of workpiece is elongated, the method cannot be carried out.
Summary of the invention
The object of the present invention is to provide a kind of locking method of ball adapter.
The present invention, by special-purpose instrument, according to the concentric principle of three circle Φ D, utilizes three circle Φ D to rotate automatically and shrink with one heart, realizes the auto lock of ball adapter, and reach ball adapter locking size and the controlled object of clearance t on common driller.
Formation of the present invention: a kind of locking method of ball adapter, it is characterized in that: the locking tool of ball adapter is contained on Drilling machines bench, the recessed connecting axle of workpiece to be machined is contained on drill press spindle, simultaneously with the locking tool of ball adapter on R profile roller concentric, the protruding rotating shaft of workpiece to be machined is contained in the R profile roller on the locking tool of ball adapter, highly by adjusting push rod, determine, main shaft during drilling machine is rotated is to pressing down, under the effect of pressure, R in R profile roller occurs rub and rotate with the protruding rotating shaft of workpiece to be machined, when drilling machine rotary main shaft continues to move downward, the recessed connecting axle of workpiece to be machined in the locking tool of ball adapter R in R profile roller under the effect of extruding force deforms, form gradually SR and realize locking.
What the locking tool of ball adapter adopted is that three R profile rollers push workpiece to be machined simultaneously, and the R size of roller R profile is identical with the R in recessed connecting axle SR.
R profile roller is arranged on moving block by screw, moving block is positioned on Drilling machines bench and around pin and is rotated by pin, in rotation process, the R profile of three R profile rollers gradually changes to pin centre distance, realized the Automatic continuous extrusion process to ball adapter assembly concave connecting axle SR profile, alignment pin plays the positioning action to moving block, and after moving block is encountered alignment pin, extrusion process finishes.
Compared with the prior art, innovative point of the present invention mainly contain following some:
1) what at the locking tool of the ball adapter shown in Fig. 2, adopt is that three R profile rollers push workpiece simultaneously, and the R size of roller R profile is identical with the R in recessed connecting axle SR.
2) in the locking tool of the ball adapter shown in Fig. 2, three R profile rollers are realized the rolling extrusion to the recessed connecting axle of workpiece to be machined under the effect of extrusion friction power, owing to being that three R profile rollers push workpiece to be machined simultaneously, the recessed connecting axle neck of workpiece to be machined radial force is zero, therefore the recessed connecting axle neck of workpiece to be machined radial deformation is zero, and the ball adapter assembly that neck is elongated is unaffected with the method processing.
3) in the locking tool of the ball adapter shown in Fig. 2 three R profile rollers along with moving block 10 axially rotates around pin 9 downwards at drill press spindle, in rotation process, three R profile roller R profiles gradually change to pin 9 centre distances, realized the Automatic continuous extrusion process to ball adapter assembly concave connecting axle SR profile, be extruded R profile roughness and be less than Ra3.2.
4) in the locking tool of the ball adapter shown in Fig. 2, the effect of support is played in 3 pairs of protruding rotating shafts of workpiece of push rod, and alignment pin 12 plays the positioning action to moving block 10, and after moving block 10 is encountered alignment pin 12, extrusion process finishes as shown in Figure 3.
5) workpiece to be machined spherical coupling assembling extruding size determines, we push measure-alike steel ball with a size and workpiece to be machined and adjust as shown in Figure 2, steel ball is expressed to behind position as shown in Figure 3, and adjust size and the clearance t of the correlated parts in the locking tool of ball adapter, realize spherical coupling assembling locking dimensionally stable.
6) the method dimensionally stable, efficiency are high.Can realize the batch machining of spherical coupling assembling locking.
Accompanying drawing explanation: Fig. 1 is traditional method of attachment schematic diagram, and Fig. 2 is the A-A cutaway view of Fig. 3, and Fig. 3 is schematic diagram of the present invention.
In figure 1, the recessed connecting axle of workpiece to be machined, 2, the protruding rotating shaft of workpiece to be machined, 3, push rod, 4, spring A, 5, R profile roller, 6, screw, 7, Drilling machines bench, 8, drilling machine three-jaw, 9, pin, 10, moving block, 11, spring B, 12, alignment pin
The specific embodiment: as shown in Figure 2, a kind of locking method of ball adapter, it is characterized in that: the locking tool of ball adapter is contained on Drilling machines bench 7, the recessed connecting axle 1 of workpiece to be machined is contained on drill press spindle, simultaneously with the locking tool of ball adapter on R profile roller 5 concentric, the protruding rotating shaft 2 of workpiece to be machined is contained on the locking tool of ball adapter in R profile roller 5, highly by adjusting push rod 3, determine, main shaft during drilling machine is rotated is to pressing down, under the effect of pressure, R in R profile roller 5 occurs rub and rotate with the protruding rotating shaft 2 of workpiece to be machined, when drilling machine rotary main shaft continues to move downward, the recessed connecting axle 1 of workpiece to be machined R in R profile roller 5 under the effect of extruding force in the locking tool of ball adapter deforms, form gradually SR and realize locking.
