Abstract
The utility model relates to a ball shifting mechanism of a table tennis ball pitching machine, and comprises a driving rod, a cam, a shifting fork rod and a reset spring, wherein, the driving rod is provided with the cam. The cam is provided with a curved surface of the cam to control swinging of the shifting fork rod. Fixed by a pivot point, and under the action of the curved surface of the cam, the shifting fork rod can wind round the pivot point while swinging, and is provided with the reset spring. With the ball shifting mechanism, and without blocking, all table tennis balls of different brands and the damaged table tennis balls can be accurately sent to the position where a friction gear is arranged, while the rhythm of beating is very accurate and easy to control.
Description
Existing table tenning ball servicing machine generally all is not provided with and dials ball mechanism, because table tennis is not stirred by this mechanism, ball just is difficult to be sent to exactly the batter's box of friction pulley, when having table tennis defective or that damage to be mixed in the inside slightly, card ball phenomenon will appear, simultaneously, also be difficult to guarantee the rhythm of batting and adjust the batting frequency.
The purpose of this utility model is to provide a kind of group ball mechanism of table tenning ball servicing machine.
The utility model adopts following technical scheme:
A kind of group ball mechanism of table tenning ball servicing machine, comprise drive link, it is characterized in that also including cam, shifting fork bar, back-moving spring wherein is equipped with cam on drive link, be provided with the cam curved surface of control shifting fork bar swing at cam, shifting fork bar is fixed by fulcrum, and can back-moving spring also be housed around a spot wobble under the effect of the cam curved surface of cam on shifting fork bar.
This group ball mechanism is set in service robot, can be with the table tennis that flows into by the goal passage, stir the friction pulley of delivering to out after the reinforcing before the ball passage by dialling ball mechanism, again ball is hit, dial ball mechanism and different plates and damaged table tennis all can be delivered to exactly the position of friction pulley, card ball phenomenon can not occur.Controlled by cam owing to dial ball mechanism, the rhythm of batting is very accurate to be controlled with being easy to.
Below in conjunction with accompanying drawing structure of the present utility model is done detailed explanation
Fig. 1 is that E-E of the present utility model is to view
Fig. 2 is a structural representation of the present utility model
Fig. 3 is the utility model cam structure schematic diagram
The utility model comprises drive link 1, cam 2, shifting fork bar 3, back-moving spring 4, wherein drive link 1 is driven by the motion that is located at its lower end and rotates, cam 2 is housed on drive link 1, be provided with the cam curved surface 5 of control shifting fork bar 3 swing at cam 2, shape as shown in Figure 3, shifting fork bar 3 is provided with two bifurcated A and B, a bifurcated A contacts with cam curved surface 5, another bifurcated B stirs table tennis with adopting, and shifting fork bar 3 is fixing by fulcrum 6, and can be around fulcrum 6 swings under the effect of the cam curved surface 5 of cam 2, back-moving spring 4 is housed on shifting fork bar 3, and assurance shifting fork bar 3 can be close to cam curved surface 5 and enough group ball strength is arranged.
The utility model is when work, driving drive link 1 by motion rotates, drive link 1 drives cam and rotates, a bifurcated A of shifting fork bar 3 is under the effect of elastic force, all the time the cam curved surface 5 that presses cam 2, when cam 2 rotates, drive shift fork 3 swings, will dial in out ball passage 9 by the table tennis that goal passage 8 falls into by another bifurcated B of shifting fork bar 3.Because table tennis is under the stirring of shifting fork bar 3, certain initial velocity is arranged, under the acceleration of friction pulley, speed and impulsive force are bigger again, make the sportsman who the stands in the other side difficulty of batting bigger, more help table tennis player's training.
