However, by the eccentric rotation of the eccentric pendulum clock 92, only a vibration in a plane direction can be achieved, and vibration perpendicular to the plane direction cannot be generated at the same time, and the vibration effect is limited, and it cannot be applied to a product requiring multi-directional vibration (such as vibration feeding). Device). Therefore, it is necessary to develop new products to solve the above shortcomings and problems. SUMMARY OF THE INVENTION An object of the present invention is to provide a uniaxial three-dimensional vibration generating device, which combines the advantages and functions of generating two-dimensional vibration and controlling the amplitude of the pumping direction, so as to solve the conventional technique, only one plane can be generated. The vibration and amplitude of the direction cannot be adjusted arbitrarily. The technical means for solving the above problems provides a single-axis three-motion generating device, comprising: a base; a motor having an input portion and an output shaft, the output shaft 22 having an outer end; The axis line of the shaft is defined as a first axis; the _ is fixed on the base; the first rotating block has a center of gravity and a pivoting end, and the pivoting end is pivotally connected thereto The outer end is spaced apart from the pivot end; when the motor is rotated and the shaft rotates, the rotating block also rotates and forms an angle with the first axis, 3 IS] 201218585 a motor control unit for rotating a power signal to an input portion of the motor, and further controlling a rotational speed of the output shaft of the motor; the power signal is a periodic electric wave and has an average voltage when the output shaft is When the rotational speed is increased from zero to a peak rotational speed, the rotation of the rotating block gradually generates axial vibration. When the rotational speed of the output shaft is further increased by the peak rotational speed, the amplitude of the axial axis gradually decreases. Only pure brittle spin . The above objects and advantages of the present invention are readily apparent from the following detailed description of the preferred embodiments. The present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a first embodiment of the uniaxial three-dimensional vibration generating apparatus of the present invention, as shown in the first and second figures, It comprises: a base 10; a motor 20' having an input portion 21 and an output shaft 22, the output shaft 22 having an outer end 221, and the axis of the output shaft 22 is defined as a first axis a wire L1; the motor 20 is fixed to the base 1; a rotating block 30' has a center of gravity 3丨 and a connecting end 32, and the pivoting end 32 is pivotally connected to the outer end 221, The center of gravity 3丨 is spaced apart from the connecting end 32; when the output shaft 22 of the motor 20 rotates, the rotating block 3〇 also rotates with an angle of 0 between the first axis L1 (this) The angle can be increased or decreased by the spring speed change; a motor control unit 40 is configured to output a power signal 4〇A to the input portion 21′ of the motor 2〇 and thereby control the speed of the output shaft 2 of the motor 2〇 The power signal 40A is a periodic electric wave and has an average voltage when the speed of the output shaft 22 is When zero is increased to a peak speed (the vertical resonance frequency of the rotating block approaches the frequency of the periodic wave), the rotation block 3〇 gradually generates axial (vertical vertical) vibrations in addition to the rotation, when this output When the rotational speed of the shaft 22 is increased by the peak spreading speed (the frequency of the recording block of the hybrid block is away from the frequency of the periodic electric wave), the amplitude of the axial direction is newly reduced and only the pure brittle rotation is performed. 201218585 Since the power signal 40A is a periodic electric wave, the rotational speed of the output shaft 22 can be controlled to change periodically; when the rotational speed of the output shaft 22 rises, the rotating block 30 and the first axis li The angle of the insertion is increased; when the rotation speed of the wheel shaft 22 is lowered, the angle between the rotation block 30 and the first axis L1 is reduced; therefore, the rotation block 30 is periodically fluctuated by the rotation speed of the motor output shaft 22. The surface is rotated and oscillated up and down to generate axial vibration, and the rotation of the rotary cymbal 30 produces a conventional lateral (or "radial") vibration. If the amplitude of the power signal supplied to the motor is increased, the fluctuation of the rotational speed of the output shaft 22 is also increased. Therefore, adjusting the amplitude of the power signal controls the amplitude of this axial vibration. The rotation, the block 3〇 is at an angle with the first axis L1, which varies according to the rotation speed of the wheel η. In other words, when the rotation speed of the output shaft 22 is not changed, the rotation block 30 is not included. The output shaft 22 rotates, and between L1, it also changes, thereby generating a radial direction (the vibration generated by the rotation of the second moving block 3〇; therefore, compared with the conventional vibration motor, 3. The angle between the angle of 22 and 22 can be changed freely: the profit is controlled by the = sign in the period: r program control = ^^ The periodic change of the wave shape can control the private, the different waves of the three, the fourth and the fifth figure Ϊ́ίΐ of the output shaft 22; such as the first voltage per voltage of the first voltage 'voltage VH1 and the lowest voltage VL1; the period of the first ten electric power of the invention of the computer simulation results; three twist (four), and respectively The amplitude variation of the axial vibration under the 201218585 is obtained by a flute line L25 and a sixth curve L26, etc. 丄ψ second, ; 24, a fifth 曲 - an amplitude change curve; The maximum amplitude change, and the Φ3 change / 囡 this feared female: quite a change in the torque of HC magnetic 23, it gets less tuned (so the most The amplitude change will occur in a certain range of speed. When the speed is too low or too low, the amplitude effect is not good.) No. 4〇 mt丨兮m20 in the Wei periodic wave (ie, the voltage is the rotation = weight: 31 Rotate and up and down: move the tenth Γ^^31 in the series of private crane Wei _, the fine ninth figure to the ninth and tenth A picture, #重重心31 is located = will the J turn block 30 and the first The height difference between the one-axis inter-system end 32 is - the first height hi. Rotating to a second position P9 dissimilar map, when the center of gravity 31 is from the first position P1, the state is downward swinging. The angle of the rotation block 30=between the first angle (four) is smaller than the second angle ′′ and the height difference 31 between the center of gravity 31 and the pivot terminal 32 is increased to a second height buckle. As shown in the first and the tenth C, when the center of gravity 31 is from the second position Ρ2 P3, the state is downwardly oscillated, and the angle between the rotation blocks 30 is reduced by the second angle. For a third degree difference, the second high-heat pure map and the tenth D-th graph show that when the center of gravity 31 is from the third position Ρ3, the line is the upward lion shape g, and the rotating block 30 is ^ The angle is increased from the third refreshing angle 03 to a fourth degree Η3 shortened to 1: the height of the pivoting end 32 is converted from the third height. As can be seen from the above description, the present invention can be controlled by periodic radio waves. The 201218585 i drives the output shaft 22 to periodically change the rotational speed so that the rotating block 30 swings up and down at the time of 'rotating block' to generate the axial vibration of the rotating block 30 __ path, which is only the rotation ^ After the rotating block 3 〇 continues to rotate, its rotating oscillating path can be formed as m? (please refer to the tenth-picture, the rotating block 3 〇 ί 系 系 α α — — 第一 第一 及 及 及 及 及 及Oh, three-dimensional vibration). In addition, as shown in the twelfth figure, the present invention can be provided with an elastic 'can be added when the rotating block 30 ^ is swung, and the Φ is increased as described above. The efficacies of the invention can be summarized as follows: 30 s. Ϊ Ϊ: The present invention utilizes periodic radio waves to make the rotating block 3 〇, so Advantages. [2] Both axial and radial vibrations can be generated at the same time. The conventional vibration is produced by the eccentric rotation of the eccentric pendulum 92, which can only reach a plane ^ ίΕο'ίίίίΙ: The hair of the hair _ Zhou New Zealand, t rotation When the block 30 is rotated, the vibration of the upper and lower sides is generated at the same time, and the degree of freedom of vibration can generate three-dimensional vibrations such as a spiral type. 9 or more, the present invention will be described in detail by the preferred embodiment, and any simple modification is made for And the changes, without departing from the spirit of the present invention =, and the details can be made, so that the person familiar with this item can understand that the invention is indeed tangible] that the patent law has been met, and the invention patent application is filed.
