Description

Technical Field

[0001] This utility model relates to the field of mechanical pressing technology, and more specifically, to a fully automatic transfer pressing device for electromagnetic valve bearings. Background Technology

[0002] A solenoid valve is a control element used to control the flow of liquids or gases. It consists of a coil, a valve core, and a valve body. Its working principle is that when current is applied to the coil, the solenoid valve generates a magnetic force that attracts the valve core, causing it to separate from the valve seat, thus allowing the medium to flow through the valve. When the coil is de-energized, the solenoid valve no longer generates a magnetic force, and the valve core returns to its original position under the action of a spring, closing the valve. The bearing installed inside the solenoid valve to support and fix the valve core is called the solenoid valve bearing. Because solenoid valves operate at high frequencies and experience significant vibrations, the bearings need to have excellent wear resistance, corrosion resistance, and fatigue resistance. Furthermore, the bearing's installation location is relatively difficult to access and operate; therefore, a specialized device is needed to accurately install the bearing inside the solenoid valve. This device is called a solenoid valve bearing press-fitting device.

[0003] For example, CN221314071U discloses a solenoid valve bearing press-fitting device, which relates to the technical field of bearing press-fitting devices. It includes a base and a support seat for supporting the base. A mounting seat is fixedly connected to the top surface of the base. The mounting seat has an internal accommodating portion for accommodating a mounting rod. A sliding plate is slidably connected inside the mounting seat. A first threaded rod is rotatably connected to the top surface of the base. The outer wall of the first threaded rod is connected to the mounting plate via internal and external threads. A guide rod is fixedly connected to the top surface of the base, penetrating the mounting plate. The outer wall of the guide rod slidably fits against the inner wall of the mounting plate. A mounting block for accommodating the bearing body is fixedly connected to the outer wall of the mounting plate. A transmission component for driving the sliding plate to slide is provided inside the mounting seat. However, although this device achieves bearing press-fitting, the process requires manual positioning of the solenoid valve before the bearing is positioned on it. This operation is time-consuming, labor-intensive, and significantly reduces work efficiency. Furthermore, manual positioning can lead to deviations or displacements, greatly affecting the yield rate and hindering mass production. Utility Model Content

[0038] The robotic arm clamps the bearing 101 into the contour groove 32 of the column 31 and clamps the solenoid valve between the positioning blocks 23. The cylinder shaft of the servo cylinder 26 extends, driving the solenoid valve 100 to abut against the protrusion 24 through the support block 27.

[0039] The drive motor 43 starts and drives the sliding plate 4 to move forward through the drive screw 42 and the drive nut until the column 31 is directly below the adsorption assembly 7. At this time, the electric cylinder 63 drives the pressing plate 5 to move downward until the adsorption nozzle 72 adsorbs the bearing 101.

[0040] After the above work is completed, the electric cylinder 63 resets. The drive motor 43 restarts, driving the sliding plate 4 to move until the solenoid valve 100 is directly below the adsorption assembly 7. At this time, the push-pull cylinder 95 is activated, causing the adsorption assembly 7 and the pressing assembly 8 to switch until the pressing assembly 8 is directly above the solenoid valve 100.

[0041] The electric cylinder 63 drives the pressing plate 5 to move downward until the pressing head 82 presses the bearing onto the solenoid valve 100.
