[0026] Specifically, when the automatic feeding and assembly equipment for pins for assembling hydraulic valves is working / in use: in the initial state, the pin workpieces 2 are stacked inside the guide rail 1, and the pin workpieces 2 of the bottom layer are blocked by the limit plate 8 and cannot fall freely. The blocking plate 16 is also located on the top of the pin workpieces 2 of the bottom layer. When the pin workpieces 2 need to be fed, the first motor 14 is started to drive the screw 10 to rotate. The rotation of the screw 10 causes the screw sleeve 11 to move inside the connecting frame 9, and at the same time drives the sleeve plate 12 and the limit plate 8 to move together. Since the sliding rod 13 is fixedly connected to the front of the screw sleeve 11 and is slidably connected to the sleeve plate 12 The shaft 7 and the limit plate 8 are connected to ensure the stable movement of the shaft 7 and the limit plate 8.

The gear 34 at the output end of the second motor 33 pushes the driven wheel 35 meshing with the sleeve block 29 to rotate. When the sleeve block 29 rotates, the thread pushes the pressure rod 28 limited by the transmission plate 27 to release the driving force. Through the reverse supporting force of the pressure rod 28 and the support plate 30, the carrying frame 22 moves horizontally to the next flipping position. At this time, the pressure rod 28 is in the The length of the left end of the transmission plate 27 is increased, while the length of the pressure rod 28 on the right side of the transmission plate 27 is shortened. When the right end of the pressure rod 28 is out of contact with the support plate 24, the support plate 24 is flipped with the pin shaft inside the vertical plate 25 as the axis, carrying the pin workpiece 2 to slide down and plug it into the hydraulic valve to be installed. At this time, the preliminary plugging of the pin workpiece 2 is completed, and then the receiving component 5 is reset and moved.

The above process is repeated continuously to form an automated pin loading and assembly cycle.
