At the same time, the fixing piece provided on the top of the fixing frame 10 can be used to fix the brush disc to be processed. At this time, the output can be performed through the first motor 2, which can drive the fixing rod 7 and the worm 8 on its surface to rotate.

[0022] By adopting the above technical solution, the brush disc can be placed on the fixed table 3 first, and then the cylinder 11 can be retracted, so that the multiple groups of support rods 13 rotatably connected to the limiting sleeve 12 can push the slider 14 rotatably connected at one end to slide in the inner cavity side wall of the fixed table 3, so that the inner wall of the brush disc can be supported and fixed by using several groups of fixing blocks 4 and elastic anti-skid pads 15, and the elastic anti-skid pads 15 can not only improve its anti-skid property and enhance its fixing stability, but also avoid wear and tear on the inner wall of the brush disc when fixing it, thereby affecting the overall production quality of the sanitation brush.

[0023] The implementation principle of a parts drilling device for the production of electric sanitation vehicles in an embodiment of the present application is as follows: a drilling tool and a corresponding drive control device assembly are provided on a drilling machine 1, which can perform drilling processing on the brush disc of the sanitation brush. First, the brush disc can be placed on a fixed table 3, at which time it can be retracted by the cylinder 11, so that the multiple groups of support rods 13 rotatably connected to the limiting sleeve 12 can push the slider 14 rotatably connected at one end to slide in the inner cavity side wall of the fixed table 3, so that the inner wall of the brush disc can be supported and fixed by using several groups of fixing blocks 4 and elastic anti-skid pads 15, and the elastic anti-skid pads 15 can not only improve its anti-skid property and enhance its fixing stability, but also avoid wear on the inner wall of the brush disc when fixing it. Etc., affecting the overall production quality of the sanitation brush. At this time, the first motor 2 can be used for output, which can drive the fixed rod 7 and the worm 8 on its surface to rotate. At this time, the fan-shaped worm gear 9 fixedly connected to one side of the support frame 6 can be driven to rotate. The support frame 6 can be used to drive the fixed frame 10 and the fixed brush disc to rotate, so that it can be tilted at a corresponding angle, which is convenient for adjustment according to different processing requirements. At the same time, the second motor 5 is used for output, which can drive the fixed frame 10 and the fixed brush disc to rotate, and each bristle installation point can be rotated to the bottom of the drilling tool in an orderly manner, thereby further improving its drilling processing efficiency. The cylinder can be selected from the TDA20 type, and the first motor 2 and the second motor 5 are both NEMA 17 stepper motors. The stepper motor consists of a rotor and a stator. The rotor usually contains a magnetic pole pair, and the stator contains a drive circuit and an electromagnetic coil. The stepper motor generates a magnetic field by applying an appropriate current to the electromagnetic coil, so that the rotor rotates at a certain step angle. Controlling the magnitude and direction of the current can control the speed and direction of rotation of the motor. The rotation of the stepper motor is carried out in units of fixed step angles, such as 1.8 degrees or 0.9 degrees. By controlling the number and frequency of the pulse signal applied to the electromagnetic coil, the angle of motor rotation can be controlled. The speed can be controlled by adjusting the frequency of the pulse signal. Higher frequencies usually result in faster speeds, and vice versa. The controller can adjust the frequency of the pulse signal as needed to achieve the desired speed. Stepper motors are usually locked in their current position when the pulse signal input stops because their rotors are held in their current position unless sufficient force is applied to move them. This self-locking function makes stepper motors very useful when they need to maintain position or prevent accidental movement. The overall operation is easy to use, the brush disc can be quickly fixed and disassembled, and the fixed angle of the brush disc can be adjusted according to processing requirements. At the same time, the bristle mounting point of the brush disc can be rotated to the bottom of the drilling tool. The overall operation can not only effectively improve its actual production and processing efficiency, but also further improve the processing quality of sanitation brushes.
