[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figure 1-3 As shown, a jack assembly device includes a supporting mechanism 200 , a refueling mechanism 300 and a press-fitting mechanism 400 , wherein the supporting mechanism 200 is used to provide support for the jack 100 , the refueling mechanism 300 and the press-fitting mechanism 400 .

[0031] Specifically, the jack 100 includes a valve core 110, a cylinder 120 and a shaft 130. The valve core 110 is located on one side of the cylinder 120. The support structure includes a support platform 210. The refueling mechanism 300 and the press-fitting mechanism 400 are both located on the support platform 210. Before assembly, the cylinder 120 and the valve core 110 can be placed on the support platform 210. The cylinder 120 is first refueled through the refueling mechanism 300. After refueling, the shaft 130 is pressed into the refueled cylinder 120 through the press-fitting mechanism 400 to complete the overall assembly of the jack 100. It has a high degree of automation and can effectively improve assembly efficiency and assembly accuracy.

[0032] Specifically, the refueling mechanism 300 includes a refueling unit, a refueling pipe 320 and a first driving unit. The oil outlet of the refueling unit is connected to the refueling pipe 320. The refueling pipe 320 has a first position located directly above the opening of the cylinder 120 and a second position away from the cylinder 120. The first driving unit can drive the refueling pipe 320 to switch freely between the first position and the second position. When the cylinder 120 needs to be refueled, the first driving unit can drive the refueling pipe 320 to be located in the first position. The refueling unit can refuel the cylinder 120 through the refueling pipe 320, that is, the refueling unit transports oil into the refueling pipe 320, and then enters the cylinder 120 through the upper opening of the cylinder 120. After refueling is completed, the refueling pipe 320 is driven by the first driving unit to move to the second position to avoid the pressing mechanism 400, so as to facilitate the next operation of the pressing mechanism 400.

[0033] Specifically, the pressing mechanism 400 includes a second driving unit, a pressing plate 420 and a pressing unit. The pressing plate 420 is connected to the second driving unit, and the pressing unit is located directly above the cylinder 120. When the refueling pipe 320 is located in the second position, the lower end of the shaft rod 130 is manually placed into the cylinder 120, and then the second driving unit can drive the pressing plate 420 to connect with the top of the valve core 110 to press down the valve core 110, and then the pressing unit presses down the shaft rod 130 to drive the shaft rod 130 downward to press the shaft rod 130 into the cylinder 120, thereby completing the assembly of the jack 100. Only when the valve core 110 is in the pressed state can the shaft rod 130 be smoothly pressed into the cylinder 120.

[0034] Specifically, an assembly area is provided on the support platform 210, and a first assembly station and a second assembly station are provided in the assembly area. A press-fitting mechanism 400 is provided on both the first assembly station and the second assembly station. Two sets of cylinder barrels 120 and valve cores 110 can be respectively located and installed on the first assembly station and the second assembly station, that is, at least two jacks 100 can be assembled at the same time, which can greatly improve work efficiency.

[0035] In order to further improve work efficiency, in the present embodiment, a third assembly station is further provided in the assembly area, and the third assembly station is located between the first assembly station and the second assembly station, and a fourth assembly station, a fifth assembly station and multiple assembly stations may be further provided, so that multiple jacks 100 may be assembled simultaneously, thereby further improving assembly efficiency.

[0036] Specifically, the refueling mechanism 300 also includes an oil tank 340, which is located in the support platform 210. The oil supply unit is set as an oil pump 310. The oil pump 310 is provided with an oil inlet and an oil outlet. The oil inlet is connected to the oil tank 340, and the oil outlet is connected to the refueling pipe 320. The oil pump 310 can extract the hydraulic oil in the oil tank 340 through the oil inlet, and after extraction, the hydraulic oil is transported to the refueling pipe 320 through the oil outlet, and refueling is carried out through the refueling pipe 320.

[0037] In order to reduce environmental pollution and improve the utilization rate of oil, an oil collecting tank 211 is also provided on the support platform 210. The oil collecting tank 211 surrounds the assembly area. In the process of refueling the cylinder 120, leakage of oil is inevitable. Under normal circumstances, the oil will fall onto the surface of the support platform 210 in the assembly area, and it will spread to the entire support platform 210, and even fall to the ground. Through the design of the oil collecting tank 211, the leaked oil can be collected in the oil collecting tank 211 to improve the working environment, and a plurality of oil collecting holes 212 that penetrate the surface of the support platform 210 are provided at the bottom of the oil collecting tank 211. The oil collecting holes 212 are located directly above the oil tank 340. The oil collected in the oil collecting tank 211 can drip into the oil tank 340 through the oil collecting holes 212 to avoid oil waste.

[0038] In order to achieve the installation and positioning of the cylinder 120, a positioning hole 213 penetrating the top surface of the support platform 210 is provided at the first assembly station and the second assembly station. The lower end of the cylinder 120 can be inserted into the positioning hole 213, and the cylinder 120 is preliminarily fixed through the positioning hole 213. The supporting structure also includes a positioning frame 220. A connecting arm 140 is provided between the valve core 110 and the cylinder 120. The positioning frame 220 includes at least two symmetrically arranged positioning plates 221. The two positioning plates 221 can be respectively located on both sides of the connecting arm 140, and can be fitted with both sides of the connecting arm 140 to clamp the connecting arm 140. The cylinder 120 and the valve core 110 are completely positioned by clamping the connecting plate to prevent them from shaking during the process of pressing into the shaft rod 130.

[0039] In this embodiment, in order to prevent the positioning frame 220 from interfering with the connecting arm 140, rotating plates 230 are symmetrically arranged on both sides of the top of the support platform 210, and a rotating shaft 240 is arranged between the two rotating plates 230. Multiple positioning frames 220 are arranged on the rotating shaft 240 at intervals. Before positioning, the positioning frame 220 can be rotated to a vertical position through the rotating shaft 240. After the cylinder barrel 120 and the valve core 110 are placed, the positioning frame 220 is rotated to a position for clamping the connecting arm 140 through the rotating shaft 240, thereby achieving clamping and positioning of the cylinder barrel 120 and the valve core 110.

[0040] In order to realize the synchronous movement of multiple refueling pipes 320, the refueling mechanism 300 also includes a fixed plate 350, and the first driving unit is set as a first driving cylinder 330. The piston rod of the first driving cylinder 330 is connected to the fixed plate 350, and the multiple refueling pipes 320 are arranged on the fixed plate 350 at intervals. That is, the synchronous movement of the multiple refueling pipes 320 can be realized through the fixed plate 350, which facilitates the synchronous refueling of the multiple cylinder barrels 120.

[0041] Specifically, the second driving unit is configured as a second driving cylinder 410, the piston rod of the second driving cylinder 410 is connected to the pressure plate 420, and can drive the pressure plate 420 to move in the horizontal direction to directly above the valve core 110, the bottom of the pressure plate 420 can be fitted with the top of the valve core 110, the downward pressing unit includes a downward pressing cylinder 430, the downward pressing cylinder 430 is arranged in the vertical direction directly above the cylinder barrel 120, and the piston rod of the downward pressing cylinder 430 can be connected to the top of the shaft rod 130, the piston rod of the downward pressing cylinder 430 performs telescopic movement in the up and down directions, when it is connected to the top of the shaft rod 130, it can drive the shaft rod 130 to move downward, thereby realizing downward pressure on the shaft rod 130.
