Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic valve body detection, in particular to an electromagnetic valve body automatic detection device and a detection system. Background Art

[0002] The solenoid valve is an industrial equipment controlled by electromagnetics. It is an automated basic component used to control fluids or gases. The basic working principle of the solenoid valve body is to control the movement of the valve core through electromagnetic force to achieve control switching. The solenoid valve usually has three terminals, two of which are the power terminals of the electromagnetic coil, and the other terminal is the power terminal. In the actual solenoid valve detection work, it is usually a manual handheld multimeter to detect the resistance of the electromagnetic coil terminal, and then detect the resistance between the ground terminal and the electromagnetic coil terminal to obtain the insulation of the ground wire. The current solenoid valve body detection equipment is not convenient for automatic switching of the project for automatic solenoid valve terminal detection. The detection efficiency is low, time-consuming and labor-intensive. At the same time, the solenoid valve terminal has poor fit, and a slight skew of the terminal can easily cause a false connection during detection. It is also not convenient for rapid detection of whether the magnetic force of the solenoid valve meets the standard. Usually, the solenoid valve is assembled and ventilated or liquid-filled for random inspection. It is difficult for traditional detection equipment to automatically prompt the results after rapid detection.

Manual work only needs to observe the resistance detection multimeter body 104, and the detection items of this structure are switched smoothly and quickly. The structure is accurate and improves the detection efficiency. At the same time, the structure can detect automatically, and can detect the electromagnetic coil and the grounding wire of the electromagnetic valve independently, which ensures the quality of the finished product of the electromagnetic valve. At the same time, the detection switching method of the structure is more direct and fast. When the sliding shaft 201 moves backward on the detection push slider 102, the contact spring 203 is further compressed. As the sliding shaft 201 moves backward on the detection push slider 102, the spiral guide groove 2011 is guided by the drag reduction ball 302, and the sliding shaft 201 will rotate in the process of moving backward, thereby driving the two contact pieces 403 to rotate, and converting the terminal for the electromagnetic coil to the fitting detection of one of the terminals of the electromagnetic coil and the grounding wire.

[0037] The terminal connector 4 includes: a terminal connection mounting column 401, a slider 402, a contact sheet 403 and a connecting rubber sheet 404.

This prevents problems such as detection errors caused by a small contact area due to direct bonding at the terminal end. At the same time, the inner edges of the two contact pieces 403 of this structure are all inclined structures. The inclined structure can facilitate the smooth insertion of the two contact pieces 403 into the side of the electromagnetic valve terminal. At the same time, the edges of the contact pieces 403 are all inclined structures, which can facilitate sliding on the outside of the terminal when the contact pieces 403 rotate to avoid jamming. The connecting rubber piece 404 uses a soft structure, which does not affect the independent bonding of the two contact pieces 403 to the electromagnetic valve terminal, and can also play a limiting role when the two contact pieces 403 rotate to switch the bonding electromagnetic valve terminals, thereby ensuring The solenoid valve terminal switches smoothly, and the structure is more reasonable, ensuring smooth detection.

At the same time, the magnetic detection structure used in this structure can quickly prompt the qualified magnetic force, which is convenient for the staff to know. At the same time, the magnetic suction alarm stroke is adjustable and can be freely adjusted according to the actual solenoid valve specifications to ensure the subsequent use of the solenoid valve. The switch control performance in use can better understand the magnetic control performance of the solenoid valve, and it is also convenient to quickly screen out defective products. The central positioning structure of the valve body clamp 5 can quickly position the solenoid valve, ensuring that the hole of the solenoid valve core in the solenoid valve is concentric with the solenoid valve core shaft 601, ensuring the installation accuracy, and avoiding problems that affect the test results. The height adjustment disk 602 can be rotated to adjust the height, and then the positioning bolt 605 can be tightened for positioning. As the height of the rotating height adjustment disk 602 is lowered, the distance between the micro switch 603 and the sliding mounting plate 105 is longer, the connecting tension spring 604 is stretched longer, and the pulling force is greater, that is, the magnetic force required by the solenoid valve is greater, which can be freely adjusted according to usage requirements.

[0040] A detection system for an automatic detection device for a solenoid valve body:

[0041] The resistance detection multimeter body 104 is used for resistance detection of the electromagnetic coil in the solenoid valve. The resistance detection multimeter body 104 is also used for insulation detection of the grounding wire of the solenoid valve. The resistance detection multimeter body 104 is electrically connected to two contact pieces 403; when the two contact pieces 403 rotate and switch, the resistance detection of the electromagnetic coil of the solenoid valve is converted to the insulation detection of the grounding wire; the two contact pieces 403 are externally connected to a power cord with a switch, which is used to power on the solenoid valve; the micro switch 603 is used to detect the height of the solenoid valve core shaft 601 being electromagnetically driven by the solenoid valve, that is, the electromagnetic force, and the micro switch 603 is electrically connected to the alarm light 106.

[0042] The working principle of this embodiment is as follows: first, insert the valve core jack of the solenoid valve into the solenoid valve core shaft 601, insert the lifting slide column 502 into the sliding installation cylinder 501, and the four inclined surfaces of the positioning frame 503 correspond to the edge of the solenoid valve for positioning. Tightening the pressing bolt 504 can drive the positioning frame 503 to press and position the solenoid valve. When the electric screw 103 drives the detection push slider 102 to move, the detection push slider 102 drives the sliding shaft 201 to move at the same time. The terminal connector 4 on the sliding shaft 201 can fit the power terminal of the solenoid valve through two contact sheets 403. The contact spring 203 will be compressed and perform elastic fitting work to ensure that the terminal and the contact sheet 403 are tightly fitted. At this time, the electromagnetic coil of the solenoid valve can be detected. Resistance value, observe the reading through the resistance detection multimeter body 104, as the electric screw 103 continues to drive the detection push slider 102 to move, the sliding shaft 201 moves backward on the detection push slider 102, and the contact spring 203 is further compressed. During the process, as the sliding shaft 201 moves backward on the detection push slider 102, the spiral structure of the spiral guide groove 2011 is guided by the drag reduction ball 302, and the sliding shaft 201 will rotate during the backward movement, driving the two contact pieces 403 to rotate, and the terminal for the electromagnetic coil is converted into the fitting detection work for one of the terminals of the electromagnetic coil and the grounding wire. At this time, observe the resistance detection multimeter body 104 to determine whether it is insulated; when the terminal is connected When the connection mounting column 401 is driven by the sliding shaft 201 to approach the terminal, the contact piece 403 can use the inclined structure on its front side to facilitate insertion into the outside of the terminal for fitting. During the fitting process, the fitting drive spring 405 can elastically squeeze the slider 402 to ensure that the contact piece 403 stably fits the solenoid valve terminal. After the two contact pieces 403 complete the electromagnetic coil detection, the sliding shaft 201 drives the terminal connection mounting column 401 to rotate. At this time, the two contact pieces 403 can fit and move outside the solenoid valve terminal. At this time, the contact pieces 403 are respectively fitted to the ground terminal and one of the terminals of the electromagnetic coil to achieve switching work. The detection push slider 102 moves back slightly, and the two contact pieces 403 are controlled to fit the electromagnetic wire of the solenoid valve. The two terminals of the circle are connected by opening the switch of the external power cord of the contact piece 403. At this time, the solenoid valve controls the solenoid valve core shaft 601 through electromagnetic force. The solenoid valve core shaft 601 slides upward by magnetic force. At this time, the connecting tension spring 604 is stretched, and the micro switch 603 can be driven to squeeze the sliding mounting plate 105 during the process. The micro switch 603 can control the alarm light 106 to light up as a prompt. The height adjustment disk 602 can be rotated to adjust the height, and then the positioning bolt 605 is tightened for positioning. As the height of the rotating height adjustment disk 602 is lowered, the distance between the micro switch 603 and the sliding mounting plate 105 is longer, and the stretching stroke of the connecting tension spring 604 will be longer, that is, the required pulling force will be greater, which can be freely adjusted according to usage requirements.
