The end cover of the oil storage cylinder placed on the conveying plate 103 can slide along the inclined surface of the conveying plate 103 into the circular hole on the placement plate 205.

[0047] Preferably, the conveying rack 201 is a concave groove, and the two side walls of the conveying rack 201 are attached to the support legs of the workbench 102; there are two parallel racks 202, and the gears 206 at the bottom of the sliding plate 203 can mesh with the racks 202. Driven by the moving motor 208, the sliding plate 203 moves on the conveying rack 201, and the racks 202 extend to both ends of the conveying rack 201; rectangular bumps are provided on the two side walls of the conveying rack 201, and corresponding grooves are provided on the side wall of the sliding plate 203. The sliding plate 203 is slidably connected to the rectangular bumps on the conveying rack 201.

[0048] Preferably, the oil storage cylinder body is fixed in advance on the sliding plate 203 at the front end of the conveying rack 201. After press-fitting, the press-fitted oil storage cylinder is removed from the sliding plate 203, and the sliding plate 203 can be removed from the conveying rack 201, so that the sliding plate 203 can be recycled.

[0049] Preferably, two rectangular rods 209 are fixed on the upper side of the placing plate 205, and the rectangular rods 209 are arranged in a funnel shape; the ends with a small distance between the rectangular rods 209 are located on both sides of the circular holes on the placing plate 205; after the oil storage cylinder end cover slides from the conveying plate 103 to the workbench 102, due to its own inertia, the oil storage cylinder end cover can continue to slide forward, and the rectangular rods 209 can guide the oil storage cylinder end cover into the circular holes on the placing plate 205.

[0050] Preferably, the fixing mold 204 is fixedly connected to the upper side of the sliding plate 203 by bolts. When press-fitting the oil storage cylinder, the lengths of different oil storage cylinder bodies are different. Therefore, multiple fixing molds 204 with different heights can be selected. According to the length of different oil storage cylinder bodies, a fixing mold 204 with a suitable height is selected, so as to facilitate the press-fitting of different oil storage cylinders.

[0051] Preferably, there is a gap between the bottom of the sliding plate 203 and the support frame; a cavity for placing the moving motor 208 is provided at a position near the bottom of the sliding plate 203; two rectangular grooves for placing the gears 206 are provided at the bottom of the sliding plate 203, and the gears 206 are rotatably connected in the rectangular grooves; there are two gears 206, one of which is fixed on the rotating shaft of the moving motor 208, and the other gear 206 can play a supporting role during the movement of the sliding plate 203.

[0052] Preferably, there are multiple spring pins 207, and the spring pins 207 are located on the inner side wall of the circular holes on the placing plate 205. The oil storage cylinder end cover entering the circular holes on the placing plate 205 will not fall under the support of the spring pins 207; the spring pins 207 are cylindrical pins, and an arc chamfer is provided at one end of the spring pin 207 in contact with the oil storage cylinder end cover, so that the spring pin 207 can be pressed into the placing plate 205 when the pressing plate 105 is pressed down.

[0053] Preferably, the bottom surface of the low-pressure workbench 102 at the bottom of the placement tray 205 is such that when the main body of the oil storage cylinder moves below the workbench 102, there is a distance for the end cover of the oil storage cylinder between the main body of the oil storage cylinder and the bottom of the placement tray 205, so that the end cover of the oil storage cylinder will not shift when it falls off the placement tray 205, ensuring that the end cover of the oil storage cylinder can fit with the round hole of the main body of the oil storage cylinder.

[0054] Preferably, sensors are fixed on both sides of the moving direction of the sliding plate 203 at the bottom of the placement tray 205. The sensors can contact the upper end of the main body of the oil storage cylinder. When the main body of the oil storage cylinder moves to a suitable position below the workbench 102, the sensors contact the main body of the oil storage cylinder. When the sensors send signals to the moving motor 208, the sliding plate 203 stops moving, so that the end cover of the oil storage cylinder can be pressed onto the main body of the oil storage cylinder.

[0055] Preferably, the fixing frame 101 is L-shaped, and the hydraulic cylinder 104 is fixed to the bottom of the fixing frame 101 by bolts; the diameter of the round hole on the pressing tray 105 is the same as that on the placement tray 205, and the thickness of the pressing tray 105 is greater than that of the placement tray 205. During pressing, the spring pin 207 in the placement tray 205 will contact the side wall of the pressing tray 105. After pressing is completed, the pressing tray 105 rises under the drive of the hydraulic cylinder 104. At this time, the spring pin 207 pops out again, stopping the next end cover of the oil storage cylinder entering the round hole of the placement tray 205 in the placement tray 205.

[0056] When the shock absorber oil storage cylinder pressing device of the embodiment of the present application is actually used:

[0057] First, the main body of the oil storage cylinder is vertically fixed on the fixed mold 204. The moving motor 208 drives the sliding plate 203 to move on the conveying frame 201. When the sliding plate 203 drives the main body of the oil storage cylinder to move to a suitable position below the workbench 102, at this time, the axis of the round hole for assembling the end cover of the oil storage cylinder on the main body of the oil storage cylinder and the round hole on the placement tray 205 are on the same straight line. The moving motor 208 stops running, and the hydraulic cylinder 104 pushes the pressing tray 105 downward. Under the pressure of the pressing tray 105, the spring pin 207 is pressed into the placement tray 205, so that the end cover of the oil storage cylinder in the round hole of the pressing tray 105 falls onto the main body of the oil storage cylinder. The pressing tray 105 continues to move downward, so that the end cover of the oil storage cylinder and the main body of the oil storage cylinder are fitted together. After pressing is completed, the sliding plate 203 drives the oil storage cylinder to continue to move forward, the pressing tray 105 resets, and the next end cover of the oil storage cylinder slides from the conveying plate 103 into the round hole of the placement tray 205. The spring pin 207 keeps it in the placement tray 205. The next sliding plate 203 moves to the lower side of the workbench 102 again, and then the above process is repeated.

[0058] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
