[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic components for controlling fluid automation. They are actuators and are not limited to hydraulics and pneumatics. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions of the control system. The most commonly used ones are one-way valves, safety valves, directional control valves, speed regulating valves, etc. There is a closed cavity in the solenoid valve, with through holes at different positions. Each hole is connected to a different oil pipe. There is a piston in the middle of the cavity and two electromagnets on both sides. The valve body will be attracted to which side the magnet coil is energized. By controlling the movement of the valve body to open or close different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then the piston of the oil cylinder is pushed by the oil pressure, and the piston drives the piston rod, and the piston rod drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current on and off of the electromagnet. The solenoid valve housing often needs to be polished and polished during production.

[0003] For example, the patent document with the announcement number CN 214025084 U discloses a polishing and grinding device for the solenoid valve housing for automobiles. The polishing and grinding device for the solenoid valve housing for automobiles includes: a base; a cavity, the cavity is opened on the base; a first motor, the first motor is fixedly installed in the cavity; a slide, the slide is opened on the base; a screw, the screw is rotatably installed in the slide, one end of the screw extends into the cavity and is fixedly connected to the output shaft of the first motor, and the threads on the screw are opposite on both sides; two driving strips, both driving strips are threadedly sleeved on the screw, and the top ends of the two driving strips extend outside the slide; a frame, the frame is fixedly installed on the top of the base; two hydraulic push rods, both hydraulic push rods are fixedly installed on the top of the base. The polishing and grinding device for the solenoid valve housing for automobiles provided by the utility model has the advantages of easy use and higher efficiency.

[0004] However, during actual use of this structure, due to the limitation of its own structure, the solenoid valve housing can only be positioned and clamped at one end and polished and ground at the other end. It is often necessary to switch the positioning and clamping of the two ends of the solenoid valve housing. At this time, the solenoid valve housing is located inside the clamping device, which will cause the equipment to have low efficiency in polishing and grinding the automobile solenoid valve housing. In addition, the structural design of polishing and grinding the automobile solenoid valve housing one by one is inefficient. At the same time, the equipment cannot efficiently collect waste chips during polishing and grinding the automobile solenoid valve housing. Waste chips are easily accumulated inside the polishing equipment, and efficient removal operations cannot be performed, which cannot meet daily use needs.

During use, the staff first puts the centers of the two sets of automobile solenoid valve shells that need to be polished into the solid material ring seats on both sides of the equipment, and then starts the driving push rods on both sides of the driving frame to drive the moving seats and solid material ring seats at their respective ends to adjust the activities of the automobile solenoid valve shells, and respectively sends one end of the two sets of automobile solenoid valve shells into the interior of the fastening covers at one end of the front control air frame and the rear control air frame. At this time, the suction unit inside the second fan seat is started, and in conjunction with the air inlet mesh slot and the first air control valve, an adaptive inflation operation can be performed from the air guide cover to the second air control valves of the front control air frame and the rear control air frame on both sides to fasten the air. The shrinking airbags and positioning clamping plates inside the storage cover on the four sides of the cover are adapted to the top connection operation with the four sides of the automobile solenoid valve housing to realize the positioning, clamping and fixing operation of the automobile solenoid valve housing. Then, the two-way adjustment push rods at both ends of the adjustment seat are started to drive the first overhead plate and the second overhead plate at each end to perform active adjustment, so that the front grinding hood and the rear grinding hood on both sides of the equipment are integrated to perform the adaptation hood connection operation with the positioning and clamping automobile solenoid valve housing on the solid material ring seat, and it is firmly positioned and clamped for polishing and grinding. At the same time, when the polishing and grinding of one end of the automobile solenoid valve housing is completed, the two-way adjustment push rods can be started first. The front grinding machine hood and the rear grinding machine hood are separated by adjusting the push rod, and then the driving push rod is started to separate the solid material ring seat carrying the automobile solenoid valve housing, and finally the driving motor on the surface of the driving frame is started to drive the driving frame to pass through the limit of the bearing seat and the positioning rubber pad on the surface of the rotating seat to perform vertical rotation operation. After the driving frame rotates, the automobile solenoid valve housings inside the two sets of solid material ring seats can be easily switched and adjusted at both ends of the automobile solenoid valve housing, and then the other end is reset for polishing and grinding. The design of synchronous processing of two sets of automobile solenoid valve housings greatly improves the overall processing efficiency of the equipment and reflects the practicality of the equipment design.
