Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, remote control ball crack, and the spacing between two balls is regulated in the lifting that can realize ball fast and automatically according to the distance or the voltage instruction of remote control.
Described remote control ball crack, comprise ball crack main body and remote controller, described ball crack main body comprises a hard-wired quiet ball and a moving ball that is promoted by lifting arm, described ball crack main body has receiver of remote-control sytem, embedded digital control system, stepping motor and transmission device, it is characterized in that: described transmission device comprises a stepping motor that has the punching drive lead screw, the guide rod tail end of the fixedly connected formation lifting arm of the front end of described screw mandrel.
Be fixed with contact on the described screw mandrel, described contact is between two stops, and stop is installed on the stop frame that sets firmly, and constitutes the position sensing device of ball crack main body.
Described ball crack main body comprise the base in fulcrum ball crack, the pillar that is fixed in base, pillar top on coil, be fixed in the quiet ball of dish and be fixed in guide rod seat on the base, the movable guide rod in the guide rod seat, the moving ball on guide rod top.
The utility model has been owing to used the stepping motor that has the punching drive lead screw, and combines with guide rod, makes the ball gap structure simple, directly.Unique ball drive system realizes direct, quick, the accurately transmission of ball.Position sensing device is realized the spacing and position automatic calibration function of displacement, thus guaranteed the ball stand-off distance from fast, accurately control.
Description of drawings

Fig. 2 is the electrical block diagram of the utility model embodiment.
Among the figure: 1-base, 2-grounding leg, 3-stepping motor, the last dish of 4-, the quiet ball of 5-, 6-moves ball, 7-guide rod, 8-guide rod seat, 9-stop frame, 10-stop, 11-contact, the 12-pillar, 13-ball crack main body, 14-remote controller, the 16-position sensing device, 17-screw mandrel, 18-receiver of remote-control sytem, 19-embedded digital control system, the 20-display, the 21-running parameter is set button.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified: remote control ball crack as shown in fig. 1, comprise ball crack main body 13 and remote controller 14, described ball crack main body 13 comprises a hard-wired quiet ball 5 and a moving ball 8 that is promoted by lifting arm, described ball crack main body 13 has receiver of remote-control sytem 18, embedded digital control system 19, stepping motor 3 and transmission device, described transmission device comprises a stepping motor 3 that has punching drive lead screw 17, guide rod 7 tail ends of the fixedly connected formation lifting arm of the front end of described screw mandrel 17.Owing to used the stepping motor that has the punching drive lead screw, and combined, made the ball gap structure simple, direct with guide rod.
Be fixed with contact 11 on the described screw mandrel 17, the motion between two stops 10 all the time of described contact 11, stop 10 is installed on the stop frame 9 that sets firmly, and constitutes the position sensing device 16 of ball crack main body.A kind of implementation as position sensing device.Position sensing device provides the position feedback information of lifting arm, and the system that makes can calibrate the displacement of moving ball automatically automatically according to position feedback, realize that simultaneously the two ends of guide rod displacement are spacing.
Described ball crack main body 13 comprises going up dish 4, be fixed in the quiet ball 5 of dish 4 and be fixed in the interior movable guide rod 7 of guide rod seat 8 on the base 1, guide rod seat 8, the moving ball 6 on guide rod 7 tops of the base 1 in fulcrum ball crack, the pillar 12 that is fixed in base 1, pillar 12 tops.
As shown in Figure 2, described position sensing device 16 and receiver of remote-control sytem 18 are electrically connected with the input interface of embedded digital control system 19, and stepping motor 3 directly or indirectly is connected with the output interface of embedded digital control system 19.
Described ball crack main body 13 has setpoint distance and the actual range parameter that running parameter display 20 can show work in real time, and the perhaps corresponding voltage parameter of She Dinging, ball crack main body will be moved ball 8 automatically and move to corresponding position.Ball crack main body 13 is under the control of embedded digital control system 19, and the distance that sets according to remote controller 14 or the magnitude of voltage of setting are controlled the suitable position of being elevated to of detent ball automatically, also can carry out the meticulous adjusting of distance according to setting.
During operation, set the displacement that button 21 is set moving ball 6 by the running parameter of ball crack main body 13, send the data to ball crack main body 13, ball crack main body 13 receives instruction by receiver of remote-control sytem 18 or main body keyboard, send embedded digital control system 19 to, control step motor 3 will move ball fast and move to command range.At this moment, unique ball drive system is given full play to its direct, quick, accurately effect of transmission, and by stepping motor 3 direct screw mandrels 17 motions, the contact 11 of screw mandrel 17 tail ends combines with stop 10 simultaneously, has both played the effect of limitting detent ball motion end value.Ball crack main body with display 20 real-time display setting distance and actual displacements, feed back to operator's real-time working situation and running parameter.During high voltage test, must keep certain safe distance, use a teleswitch and send the ball stand-off distance from regulating command with the ball crack.
