Two above-mentioned counterbalance weights at the mounting structure on two connecting rods are: the through hole of equal intervals is arranged on two connecting rods, and every counterbalance weight has the through hole inserting installation of inserting on axle and the connecting rod.
Two above-mentioned connecting rod lower ends with the vertical syndeton of output shaft of two motors are: two cylinders of difference wringing fit socket on the output shaft of two motors, the side direction of two cylinders have through hole respectively with the lower end wringing fit inserting of two connecting rods, and be connected have in the section of inserting in cylinder perforation just in time also with the inserting of motor output shaft wringing fit.
The structure of above-mentioned connection framework is: the fixedly connected end cap in the rear end of a sleeve, and front end is by the fixedly connected clamp device of flange; Described motor mounting plate is fixedlyed connected with end cap, makes two motors and sleeve coaxial cable; There is the semilune groove at the middle part of sleeve, make two connecting rods and on two counterbalance weights extend in outside, and two connecting rods can be swung in 180 ° of scopes.
Above-mentioned clamp device is scroll chuck or four-jaw chuck; The clamping surface of its claw is a curved surface.
The utility model compared with prior art, have following conspicuous outstanding substantive distinguishing features and remarkable advantage: the connection framework is arranged in the utility model, one end of its clamp device can clamp with the rotating shaft that is balanced rotor and connect, and the end cap of the other end can connect with the rotating shaft of equilibrator, by controlling two motors in this automatic balancing device, then can adjust the phasing degree of two counterbalance weights, by the different insertings hole of counterbalance weight on connecting, adjustable leveling weighing apparatus moment.Of the present utility model simple in structure, easy to use, can guarantee right alignment, the production efficiency height.

Embodiment
Details are as follows in conjunction with the accompanying drawings for a preferred embodiment of the present utility model:
As shown in Figure 1, present embodiment has two motors 6,9, motor shaft conllinear and be installed on the motor mounting plate 8 in relative mode, and the distance between them is by connecting rod 5,3 and counterbalance weight 2,4 decisions.The motor shaft line should intersect with end cap 1 center pit.Because in the trim process, need to calculate the phase place of amount of unbalance, what therefore select for use is magneto, not only can control angle, and bulk is little, can be with bigger torque work.Motor is powered by slip ring, and slip ring is not arranged in the whole device, and data line penetrates the control motor from the center pit of end cap.Connecting rod 5,3 one ends can be connected with motor output shaft, and the other end connects counterbalance weight 2,4, as Fig. 2.In the present embodiment, connecting rod 3 passes earlier in the cylinder 10, and motor output shaft is inserted in cylinder 10 and connecting rod 3 more successively, and here each part both can wringing fit, also can be to spile to connect by web member.Equally, counterbalance weight can be connections such as pin, bolt, screw with being connected of connecting rod.Motor 6,9 drives the counterbalance weight 2,4 on motor shaft drivening rod 5,9 connecting rods.Counterbalance weight 2,4 is made circular motion around electrical axis within the specific limits, and their maximum angle differences are 180 °.The through hole of default equal intervals on the connecting rod 5,3 is used for the position of adjustment piece 2,4.The center of two counterbalance weights 2,4 is on the same one side perpendicular to axis.Counterbalance weight 2,4 adopts the bigger derby of density, and volume is little like this, and quality is relatively concentrated.Mass of balance block can not be too big, because excessive counterbalance weight may increase the weight of the destruction to other parts.2～3 times that generally should choose this rotor allowable amount of unbalance get final product.In addition, for the ease of installing connecting rods 5,3, can punch corresponding on connecting rod 5,3 and the position that motor shaft is connected at motor mounting plate 8 and sleeve 11.
As Fig. 3, end cap 1 connects a sleeve 11 at the homonymy that motor mounting plate 10 is installed, and sleeve 11 central authorities open a groove, can expose connecting rod 5,3 and counterbalance weight 2,4 like this.Sleeve 11 other ends connect clamp device 13 by flange 12.In the present embodiment, clamp device 13 is a scroll chuck, can certainly be the anchor clamps of four-jaw chuck and so on, and excessive so that damage the surface of rotor for fear of clamping force, the working surface of clamping element 14 is curved surfaces 15 on the anchor clamps.
Anchor clamps one end of two automatic balancing devices 16 is connected with rotor 17 respectively, and the rotating shaft in the fixedly connected dynamic balancing machine support of the other end so structurally just can realize full-automatic balance.As shown in Figure 4.
