The working principle and the advantages of the invention are as follows: when the device is used, the microcontroller controls the first electromagnet and the second electromagnet to be electrified to clamp a threaded workpiece, the end of the cleaning rod is placed in a threaded gap of the end of the threaded workpiece, then the microcontroller controls the motor to rotate forwards, so that the rocker fixedly connected to the output shaft of the motor drives the sliding block to slide along the side wall of the air cylinder, and the cleaning rod moves along the threaded gap of the threaded workpiece in the sliding process of the sliding block, so that the threaded workpiece moves towards the direction of the hydraulic cylinder; in the moving process of the threaded workpiece, a piston of the air cylinder slides towards the air cylinder, negative pressure is generated in the air cylinder, external air enters the air cylinder from the vent hole, meanwhile, the piston of the hydraulic cylinder moves towards the hydraulic cylinder, so that liquid in the hydraulic cylinder is extruded, the liquid in the hydraulic cylinder flows out from a flushing pipeline, and substances such as dust or oil and the like on the threaded workpiece are cleaned;
if the depth of a thread gap on a threaded workpiece is originally required to be consistent, once the depth of the thread on the threaded workpiece to be cleaned is changed, the cleaning rod moves upwards or downwards to change the distance between the first capacitor plate and the second capacitor plate, the electric charge quantity detected by the second current sensor is changed after the distance between the first capacitor plate and the second capacitor plate is changed, and at the moment, the second current sensor sends a corresponding electric signal to the microcontroller; when the piston of the hydraulic cylinder abuts against the second button, the second button sends an electric signal to the microcontroller, and then the microcontroller controls the first electromagnet and the second electromagnet to be powered off according to the electric signal sent by the second current sensor and the electric signal sent by the second button, so that the workpiece falls into a second placing frame below the hydraulic cylinder; if the depth of the threads on the threaded workpiece to be cleaned is consistent, when the piston of the hydraulic cylinder abuts against the second button, the second button sends an electric signal to the microcontroller, and then the microcontroller controls the motor to rotate reversely, so that the threaded workpiece moves to one side of the cylinder;
when the threaded workpiece moves to one side of the cylinder, gas in the cylinder is extruded and comes out from the vent hole on the piston of the cylinder, so that evaporation of residual moisture on the threaded workpiece is accelerated; meanwhile, a piston of the hydraulic cylinder moves towards one side of the air cylinder, so that the water level in the hydraulic cylinder is reduced, water in the water accumulation cylinder enters the hydraulic cylinder from the one-way valve, meanwhile, the water in the hydraulic cylinder cannot enter a flushing pipeline, and once the motor rotates reversely, the flushing pipeline stops flushing the threaded workpiece;
when the thread is cleaned by the flushing pipeline, substances such as dust and the like cleaned from the thread workpiece are remained on the water for flushing the thread workpiece, the water receiving frame arranged on the air cylinder collects the water for cleaning the thread workpiece, and due to the existence of the substances such as dust and the like in the water, compared with the clear water, the conductivity of the water is changed, and the size of the change of the conductivity of the water represents the dust content in the water; the change of the conductivity of the water causes the current amount in the loop of the first current sensor to change;
when the piston of the air cylinder continues to move towards the air cylinder until the piston abuts against the first button, the first button sends an electric signal to the microcontroller, if the current variation of a loop where the first current sensor is located is not large after the water receiving frame receives water, the thread workpiece is cleaned, and at the moment, the microcontroller controls the first electromagnet and the second electromagnet to be powered off according to the electric signal transmitted by the first current sensor and the signal transmitted by the first button, so that the thread workpiece falls into the first placing frame; if the first current sensor detects that the current change in the loop where the first current sensor is located is still large, when the piston of the air cylinder touches the first button, the microcontroller controls the motor to rotate forwards according to the electric signal transmitted by the first current sensor and the electric signal transmitted by the first button, and the threaded rod is cleaned continuously; in addition, when the piston on the cylinder touches the first button, the microcontroller controls the electromagnetic valve at the bottom of the water receiving frame to be opened and then closed, so that water in the water receiving frame flows out, and water can be stored for the next time.
The scheme realizes the detection on whether the depths of the thread gaps in the thread workpieces are consistent through the first capacitor plate, the spring, the second capacitor plate, the power supply and the second current sensor, and solves the problem that the thread gaps are difficult to detect by the thread workpieces requiring consistent thread gap depths; meanwhile, the spring has certain elasticity, so that the cleaning rod can be prevented from damaging the threaded workpiece when the cleaning rod cleans the threaded workpiece; whether the threaded workpiece is clean or not is detected through the water receiving frame, the power supply and the first current sensor, and the threaded workpiece is repeatedly cleaned before being cleaned, so that the threaded workpiece is ensured to be cleaned; the threaded workpieces with the thread gap depths meeting and not meeting the requirements are respectively and automatically placed through the microcontroller, the first electromagnet, the second electromagnet, the first placing frame and the second placing frame;
rotate through the clearance pole and drive the screw thread work piece and rotate, rotate with the screw thread work piece and drive the clearance pole action and compare, will clear up each screw thread gap in the screw thread work piece when the clearance pole rotates, and if use the threaded rod to rotate and drive the action of clearance pole, the clearance pole still probably acts on along with the screw thread work piece because of the friction when the screw thread gap of the screw thread work piece that drops so, causes the screw thread gap clearance of screw thread work piece not to arrive in place.
Further, a waste water storage box is arranged under the cleaning rod.
Waste water for cleaning the threaded workpiece is collected through the waste water storage box, so that water is prevented from flowing everywhere.
Furthermore, the middle of the wastewater storage box is provided with a separation fence higher than the side wall of the wastewater storage box, and a sieve plate is arranged between the separation fence and the wastewater storage box.
Water for cleaning the threaded workpiece falls onto the sieve plate, and then enters the wastewater storage box from the sieve plate for storage; when the first electromagnet and the second electromagnet are powered off, the threaded workpiece falls onto the sieve plate and then slides into the first placing frame or the second placing frame along with the inclined sieve plate.
Further, a bearing is arranged on the output shaft of the motor, and the cylinder is fixedly connected with the bearing.
The bearing is arranged on the output shaft of the motor, so that the air cylinder does not rotate along with the rotation of the output shaft of the motor.
Furthermore, the contact end of the cleaning rod and the threaded workpiece is matched with the threaded gap of the threaded workpiece.
The end that clearance pole and screw thread work piece contact cooperatees with the screw thread gap of screw thread work piece and can make the clearance pole all clean up each corner of screw thread gap when clearing up the screw thread gap.
Further, a waterproof sleeve is arranged on the second button.
The waterproof sleeve is arranged on the second button, so that the second button can be prevented from being damaged due to the fact that water enters the second button.
