Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
本发明的提供一种用于砻谷机的摆臂测量装置，该摆臂测量装置包括，横向移动轴，与胶辊平行设置；The invention provides a swing arm measuring device for a grain hulling machine. The swing arm measuring device includes a lateral movement shaft, which is arranged in parallel with the rubber roller;
舵机，设置在所述横向移动轴上，能够沿着横向移动轴移动；The steering gear is arranged on the lateral movement axis and can move along the lateral movement axis;
摆臂，一端可转动地设置在所述舵机上；a swing arm, one end of which is rotatably arranged on the steering gear;

测速轮，安装在所述摆臂的另一端，用于测量胶辊的转速；A tachometer wheel, installed at the other end of the swing arm, is used to measure the rotational speed of the rubber roller;
控制单元，与所述角度传感器和测速轮通信连接，基于测量的角度信号和转速信号计算。A control unit, connected in communication with the angle sensor and the tachometer wheel, calculates based on the measured angle signal and the rotational speed signal.
如图1所示，可以通过角度传感器测量出摆臂的转动角度α，O1为摆臂的转轴中心，O2为测速轮的转轴中心，O3为胶辊的转轴中心。O1与O2之间的距离时固定的，O1与O3之间的距离时固定的，O3与O2之间的距离由于胶辊磨损所以是未知的。测量出摆臂的转动角度α后，可以通过Sinα，计算出O3与O2之间的距离，减去测速轮体的半径，获得胶辊此位置处的半径，与胶辊标准半径相减，能够计算出胶辊的半径减少量。As shown in Figure 1, the rotation angle α of the swing arm can be measured by the angle sensor, O 1 is the center of the swing arm's rotation axis, O 2 is the center of the rotation axis of the tachometer wheel, and O 3 is the center of the rotation axis of the rubber roller. The distance between O 1 and O 2 is fixed, the distance between O 1 and O 3 is fixed, and the distance between O 3 and O 2 is unknown due to rubber roller wear. After measuring the rotation angle α of the swing arm, you can calculate the distance between O 3 and O 2 through Sinα, subtract the radius of the tachometer wheel body, and obtain the radius of the rubber roller at this position, which is subtracted from the standard radius of the rubber roller. , the radius reduction of the rubber roller can be calculated.
进一步地，舵机在横向移动轴上运动(通过控制单元控制舵机左右运行)，测量不同位置处的摆臂转动角度，计算出该位置处的胶辊的直径减少量。这样就可以测出胶辊纵向每一位置的直径减少量。Further, the steering gear moves on the lateral movement axis (the steering gear is controlled by the control unit to run left and right), the rotation angle of the swing arm at different positions is measured, and the diameter reduction of the rubber roller at the position is calculated. In this way, the diameter reduction of each position in the longitudinal direction of the rubber roller can be measured.
进一步地，所述舵机包括摆臂驱动装置和电磁离合器，所述摆臂驱动装置通过电磁离合器驱动所述摆臂正向摆动或反向摆动。所述测速轮表面设置有接触传感器，与所述控制单元通信连接；所述电磁离合器与所述控制单元通信连接，所述控制单元基于接触传感器检测的信号控制所述电磁离合器的分离与闭合。Further, the steering gear includes a swing arm driving device and an electromagnetic clutch, and the swing arm driving device drives the swing arm to swing forward or reversely through the electromagnetic clutch. The surface of the speed measuring wheel is provided with a contact sensor, which is communicatively connected to the control unit; the electromagnetic clutch is communicatively connected to the control unit, and the control unit controls the separation and closing of the electromagnetic clutch based on the signal detected by the contact sensor.
进一步地，所述测速轮包括：测速轮体，内部为中空结构，设置有两块对称分布的弧形磁铁；动生电金属网，安装在所述测速轮体的内部，所述动生电金属网为圆筒形，两端设置有集流金属圈，集流金属圈通过导线连接到外部电流表。所述测速轮体可转动地安装在所述摆臂的另一端，所述动生电金属网固定地安装在所述摆臂的另一端。Further, the speed measuring wheel includes: a speed measuring wheel body, the interior is a hollow structure, and two symmetrically distributed arc-shaped magnets are arranged; The metal mesh is cylindrical, and the current collecting metal rings are arranged at both ends, and the current collecting metal rings are connected to the external ammeter through wires. The speed-measuring wheel body is rotatably mounted on the other end of the swing arm, and the motion-generated electric metal mesh is fixedly mounted on the other end of the swing arm.
测速轮体部分与胶辊接触时，测速轮体与胶辊达到线速度同步状态。测速轮体带动弧形磁铁转动，内部的动生电金属网固定不动，因而动生电金属网的金属线相对两块弧形磁铁产生的磁感线发生切割运动，产生电动势进而从两端的导线与外部电流表形成通路，根据已知的磁感应强度大小，切割金属线的长度，可以计算出测速轮的转速。根据测速轮体半径计算得出测速轮体的线速度，由于测速轮体与胶辊的线速度相同，因此可以得到胶辊的线速度，根据胶辊的半径可计算出胶辊的转速。When the speed-measuring wheel body is in contact with the rubber roller, the speed-measuring wheel body and the rubber roller reach the state of line speed synchronization. The tachometer wheel drives the arc-shaped magnet to rotate, and the internal dynamic electric metal mesh is fixed, so the metal wire of the dynamic electric metal mesh cuts relative to the magnetic field lines generated by the two arc-shaped magnets, generating electromotive force and then from the two ends. The wire forms a path with the external ammeter, and the speed of the tachometer wheel can be calculated according to the known magnetic induction intensity and the length of the cut metal wire. According to the radius of the tachometer wheel body, the linear speed of the tachometer wheel body is calculated. Since the tachometer wheel body and the rubber roller have the same linear speed, the linear speed of the rubber roller can be obtained, and the rotation speed of the rubber roller can be calculated according to the radius of the rubber roller.
根据本发明的另一个方面，提供一种用于砻谷机的摆臂测量方法，其特征在于，该方法包括：According to another aspect of the present invention, there is provided a swing arm measurement method for a grain hulling machine, characterized in that the method comprises:
步骤1：舵机驱动摆臂偏转，使得测速轮体的表面接触胶辊；Step 1: The steering gear drives the swing arm to deflect, so that the surface of the speed measuring wheel body contacts the rubber roller;

步骤7：控制舵机沿横向移动轴移动到不同位置，重复步骤1-5。Step 7: Control the servo to move to different positions along the lateral movement axis, repeat steps 1-5.
在舵机中有电磁离合器，此电磁离合器受控制单元控制，摆臂的一端与舵机转动连接，另一端与测速轮体转动连接，测速轮体的内部是测速电机，测速轮体的表面有接触传感器。当电源打开时舵机开始工作，驱动摆臂偏转，当测速轮体表面的接触传感器接触胶辊后，控制单元控制电磁离合器分离，此时摆臂保持此状态不动，角度传感器测出摆臂的转动角度，测速电机测出此时胶辊的速度，并将此信息反馈给控制单元进行计算。之后，舵机逆转，控制电磁离合器闭合，驱动摆臂反转，(可设置挡板防止摆臂回转过大)，测速轮体脱离胶辊。然后舵机沿着横向移动轴移动到另一位置，控制单元重复上述测量操作，角度传感器测出角度，测速电机测出速度，并将此信息反馈给控制单元，反复执行上述过程可以得到胶辊每个位置的直径减少量。There is an electromagnetic clutch in the steering gear. This electromagnetic clutch is controlled by the control unit. One end of the swing arm is rotationally connected to the steering gear, and the other end is rotationally connected to the tachometer wheel body. The inside of the tachometer wheel body is a tachometer motor. touch sensor. When the power is turned on, the steering gear starts to work and drives the swing arm to deflect. When the contact sensor on the surface of the speed measuring wheel body contacts the rubber roller, the control unit controls the electromagnetic clutch to separate. At this time, the swing arm remains in this state, and the angle sensor detects the swing arm. The speed of the rubber roller at this time is measured by the speed measuring motor, and this information is fed back to the control unit for calculation. After that, the steering gear is reversed, the electromagnetic clutch is controlled to close, the swing arm is driven to reverse, (a baffle can be set to prevent the swing arm from turning too much), and the speed measuring wheel body is separated from the rubber roller. Then the steering gear moves to another position along the lateral movement axis, the control unit repeats the above measurement operation, the angle sensor measures the angle, the speed measuring motor measures the speed, and feeds this information to the control unit, and repeating the above process can get the rubber roller Diameter reduction at each location.

当测速轮体的表面接触胶辊时，控制电磁离合器分离，使得摆臂与胶辊保持接触状态，利用角度传感器测出摆臂的转动角度，利用测速轮的测速电机测出测速轮体的速度，控制单元根据摆臂的转动角度计算出接触位置处的胶辊直径，根据测速轮体的速度计算出胶辊速度；When the surface of the tachometer wheel body contacts the rubber roller, the electromagnetic clutch is controlled to separate, so that the swing arm and the rubber roller are kept in contact, the rotation angle of the swing arm is measured by the angle sensor, and the speed of the tachometer wheel body is measured by the tachometer motor of the tachometer wheel. , the control unit calculates the diameter of the rubber roller at the contact position according to the rotation angle of the swing arm, and calculates the speed of the rubber roller according to the speed of the speed measuring wheel;
接下来，控制电磁离合器闭合，使得摆臂反转，测速轮体的表面脱离胶辊；Next, the electromagnetic clutch is controlled to close, so that the swing arm is reversed, and the surface of the speed measuring wheel body is separated from the rubber roller;
控制舵机沿横向移动轴移动到不同位置，重复之前的测量步骤，控制单元再次启动控制过程，由此测量胶辊各个位置处的直径和速度。The steering gear is controlled to move to different positions along the lateral movement axis, the previous measurement steps are repeated, and the control unit starts the control process again, thereby measuring the diameter and speed of the rubber roller at each position.
最后，测量完成，关闭砻谷机。Finally, when the measurement is completed, the grain husker is turned off.
