Operation principle and using method of the present invention：Set in impact tennis area twice concentric semicircles arc track 4120,
4130, semicircular arc track 4120,4130 is open towards tennis net, the machine is placed on track, the first sheave 411 and second
Individual sheave 412 is placed on large radius semicircular arc track 4120, and the 3rd sheave 413 is placed on minor radius semicircular arc track 4130
On, then start the machine, three motors 1 are under the programme-control of setting, and the driving sheave 411 of the 3rd frequency conversion motors 13 exists
Reciprocated on semicircular arc track 4120, also drive the equipment and reciprocated on two tracks；Second stepper motor
12 drive the hemispherical ball mould 31 in ox horn formula funnel 3 to rotate through angular wheel 121,33, and the ball mould 31 in ox horn formula funnel 3 will
Tennis is put into the service robot 111 in snail sandwich type element 2 one by one, and service robot 111 is made in the driving of the first frequency conversion motors 11
Tennis is set to be moved to from the bigger diameter end of service robot 111 at the oval mouth of the miner diameter end of service robot 111 by spring with the centrifugal force of lower generation
Formula right angled triangle controlling switch 1113 is controlled, when the miner diameter end of service robot 111 turns to the upper side of 2 ball mouth of snail sandwich type element 22
On rectangular opening 24 when, right angled triangle controlling switch 1113 is touched by the firing device 122 on second axle of stepper motor 12
On sliding shoe 11136, sliding shoe 11136 along rectangle guide groove 11137 slide be pressed into right angled triangle controlling switch
In rectangular opening on 1113 right angles end, the big acute angle moment of the right angled triangle controlling switch 1113 stretched into service robot 111 becomes
Greatly, stretch to outside service robot 111, tennis departs from service robot 111 and enters bulb 25 through the ball mouth 22 of snail sandwich type element 2, is going out ball
The lower drive belt tooth turning rolls 2505 of gear 123 produced on rotation, second axle of stepper motor 12 of the helix of pipe 25 effect is rotated,
Under the effect of large size roller, the isometrical roller of medium size and small size isometrical roller 250, go out bulb 25 and produce twisting, make impact to training
The tennis direction of member with and change, the also adjustable high ball of adjustable bead, the cunning in right angled triangle controlling switch 1113
Motion block 11136 sets back under the spring effect of its one end, and the big acute angle 11132 of right angled triangle controlling switch 1113 diminishes
It extend into again in service robot 111, control next ball, repeat said process, the equipment can continues training mate ball.Due to the 3rd groove
There is eccentric shaft to be flexibly connected through drive link 42 with the small axle 23 of the one side of the ball mouth 22 of snail sandwich type element 2 on wheel 413, impact tennis
Angle can continuously change, and driven to trainer's offer service, froehand-backhand, adjust the highly difficult training actions such as ball, impact smash, plus
The twisting for going out bulb 25, output direction of ball is combined consecutive variations, can train athletes respond and flexible ability,
The skill improvement of trainer is fast.If some action to trainer is trained, by the machine be parked in some position on track,
And the ball launch angle of the action is adjusted with drive link, the gear of the 3rd stepper motor shaft end is unloaded again, bulb 25 is conceded and twists
The position needed to the training action.
