Implement four: composition graphs 1 illustrates the present embodiment, the dynamical system of the present embodiment comprises pneumatic supply (9), pneumatic control valve D1, D2, D3 and choke valve J1, J2, J3 are formed, described choke valve J1 connects and regulable control pneumatic control valve D1 and air motor (10), described choke valve J2 connects and regulable control pneumatic control valve D2, described J3 connection control adjustable pressure control valve D3, thus can stroke pressure be realized and speed is adjustable.
Implement five: composition graphs 4-Fig. 8 and the present embodiment is described, the emission system of the present embodiment comprises bulb road (6), reversing cylinder (7) and service cylinder (8).The one end going out bulb road (6) close service cylinder (8) is the flexible pipe (17) connecting described goal pipeline (4), one end close to ball mouth is that hard goes out ball thorax (12), at flexible pipe (17) with go out between ball thorax (12) to be provided with one section of double-skin duct (5), this double-skin duct (5) skin is hard material sleeve (14), inside establish one deck liner (15), double-skin duct (5) with go out ball thorax (12) and flexible pipe (17) is connected for be detachably socketed, dismounting can be needed according in training; Go out ball thorax (12) inwall side arrange one piece shaggy go out ball thorax inner lining plate (13), this structure can make the ball sent have different direction of rotation, obtain top spin, chop, side spin, meet tennis practitioner different phase, the training of different difficulty; Air motor (10) drives standby ball dish (11) to rotate by a rotating shaft (19).Tap into bulb road (4) under standby ball dish (11), tennis, in standby ball (18), controls tennis by Valve controlling cylinder (3) and enters goal pipeline (4); Standby ball dish (11) has a ring of blocking (20) below, and tennis is temporarily trapped in all the other in ball under ring of blocking (20) intercepts, and this ball mode of getting of this structure not only can not cause tennis stuck in ball-storing box (1), but also need not hinder ball sheet; Pneumatic control valve D1 controls service cylinder (8), realizes tennis and launches with larger kinetic energy, and built-in spring can realize cylinder and reset; Reversing cylinder (7) connects and controls out the angle of bulb road (6), realizes tennis to different directions to move; Described Valve controlling cylinder (3) by-pass valve control (2) switch, taps into bulb road (4) under standby ball dish (11), double-skin duct (5) taps into bulb road (4), under pick out bulb road (6); Reversing cylinder (7) controls out the angle of bulb road (6), and service cylinder (8) controls the dynamics that tennis is launched, and realizes the once transmitting of tennis.
Implement six: composition graphs 6 and Fig. 7 illustrate the present embodiment, and the ball thorax structure function that goes out of the present embodiment is described as follows: tennis is taken into and after entering goal pipeline, under the pressure of low pressure air pressure, enters into out ball thorax along goal pipeline in supply and demand system.To when going out the fastening spring circle place of ball thorax, be clamped and stop.Now sensor sensing to tennis arrival and send a signal to the control valve of blow cylinder, make control valve action, ball got.Going out ball thorax mouth place and have a slice spring leaf, stick, for controlling the direction of rotation of tennis, certainly, also can not stick.The junction anti-attrition ball going out bulb road and goal pipeline stops, and the connection of two parts can not be too tight, with the direction of rotation facilitating the rotation in bulb road to control tennis.Meanwhile, in order to ensure out that bulb road does not loosen in the axial direction, designing an axial location groove in the fixed position going out bulb road, coordinating with retainer plate to prevent out the movement in the axial direction of bulb road.
Operation principle:
1) start power supply, set the working time, serving side to (directed service or break-in service), serve speed; Press " beginning " key, spend half a minute, program enters operation automatically.
2) to be that D1 obtains electric for initial actuating, and valve cylinder 3 piston is to left movement, and valve 2 is opened, and the ball in standby ball dish falls into goal pipeline, sensor S1 inspires, S1 control D1 dead electricity, and valve 2 is closed, goal pipeline pressurizes, and tennis is pushed to double-skin duct place and clamps, and sensor S2 inspires;
3) after S2 inspires, the D2 of dead electricity controls electric by S2, service cylinder 8 action, piston rod high-speed impact tennis and make tennis obtain very high speed outwards to penetrate.Tennis inspires sensor S3 when going out ball thorax by hard;
4), after S3 actuates, control D2 dead electricity, service cylinder 8 piston rod is regained.Simultaneously by software control after setting-up time, D1 obtains electric, repeats next circulation.Conversion time after setting-up time has frequency setting in fact herein controls.
5) for tennis after preventing machine operation stays in service pipeline, when also having one point of end from knocking-off time, software control enters machine and enters another working procedure, this program implement is: unconditionally make D1 power-off, and after crossing 5s, D2 obtains electric, after 5s, D2 power-off, its elsewhere normality.
6) D3 is by software control, if be set as directed service when starting, then D3 is failure to actuate; If setting break-in service when starting, then D3 obtains dead electricity by software control.
