[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figure 1-3 As shown, a jack assembly device includes a support mechanism 200, an oiling mechanism 300, and a pressing mechanism 400. The support mechanism 200 is used to provide support for the jack 100, the oiling mechanism 300, and the pressing 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 lubrication mechanism 300 and the pressing 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 lubrication mechanism 300 lubricates the cylinder 120. After lubrication, the pressing mechanism 400 presses the shaft 130 into the lubricated cylinder 120, thus completing the overall assembly of the jack 100. It has a high degree of automation and can effectively improve assembly efficiency and accuracy.

[0032] Specifically, the refueling mechanism 300 includes an oil supply unit, a refueling pipe 320, and a first drive unit. The oil outlet of the oil supply 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 located away from the cylinder 120. The first drive unit can drive the refueling pipe 320 to freely switch between the first position and the second position. When the cylinder 120 needs to be refueled, the first drive unit can drive the refueling pipe 320 to the first position. The oil supply unit can refuel the cylinder 120 through the refueling pipe 320. That is, the oil supply unit delivers oil into the refueling pipe 320, and then enters the cylinder 120 through the upper opening of the cylinder 120. After the refueling is completed, the first drive unit drives the refueling pipe 320 to move to the second position to avoid the pressing mechanism 400 and facilitate the next operation of the pressing mechanism 400.

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

[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. Both the first assembly station and the second assembly station are equipped with a pressing mechanism 400. Two sets of cylinders 120 and valve cores 110 can be installed on the first assembly station and the second assembly station respectively, that is, at least two jacks 100 can be assembled at the same time, which can greatly improve work efficiency.

[0035] To further improve work efficiency, in this embodiment, a third assembly station is provided in the assembly area. The third assembly station is located between the first assembly station and the second assembly station. Furthermore, multiple assembly stations such as a fourth assembly station and a fifth assembly station can be added, thereby enabling multiple jacks 100 to be assembled simultaneously, further improving assembly efficiency.

[0036] Specifically, the refueling mechanism 300 also includes an oil tank 340, which is located inside the support platform 210. The oil supply unit is a pump 310, which has 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 pump 310 can draw hydraulic oil from the oil tank 340 through the oil inlet, and after drawing, it can deliver the hydraulic oil to the refueling pipe 320 through the oil outlet for refueling.

[0037] To reduce environmental pollution and improve oil utilization, an oil collection trough 211 is provided on the support platform 210. The oil collection trough 211 surrounds the assembly area. During the process of adding oil to the cylinder 120, oil leakage is inevitable. Under normal circumstances, the oil will fall onto the surface of the support platform 210 in the assembly area and spread throughout the entire support platform 210, or even fall to the ground. The design of the oil collection trough 211 allows the leaked oil to be collected in the oil collection trough 211, improving the working environment. At the bottom of the oil collection trough 211, there are multiple oil collection holes 212 penetrating the surface of the support platform 210. The oil collection holes 212 are located directly above the oil tank 340. The oil collected in the oil collection trough 211 can drip into the oil tank 340 through the oil collection holes 212, avoiding oil waste.

[0038] To achieve the installation and positioning of the cylinder 120, positioning holes 213 penetrating the top surface of the support platform 210 are provided at both the first and second assembly stations. The lower end of the cylinder 120 can extend into the positioning hole 213, and the cylinder 120 is initially fixed through the positioning hole 213. The support 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 located on both sides of the connecting arm 140 and can fit against both sides of the connecting arm 140 to clamp the connecting arm 140. By clamping the connecting plates, the cylinder 120 and the valve core 110 are completely positioned to prevent them from shaking during the pressing of the shaft 130.

[0039] In this embodiment, to avoid interference between the positioning frame 220 and the connecting arm 140, rotating plates 230 are 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 at intervals on the rotating shaft 240. Before positioning, the positioning frame 220 can be rotated to a vertical position through the rotating shaft 240. After the cylinder 120 and valve core 110 are placed, the positioning frame 220 is rotated to the position of clamping the connecting arm 140 through the rotating shaft 240 to achieve clamping and positioning of the cylinder 120 and valve core 110.

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

[0041] Specifically, the second drive unit is configured as a second drive cylinder 410. The piston rod of the second drive cylinder 410 is connected to the pressure plate 420 and can drive the pressure plate 420 to move horizontally to directly above the valve core 110. The bottom of the pressure plate 420 can fit against the top of the valve core 110. The pressing unit includes a pressing cylinder 430. The pressing cylinder 430 is arranged vertically directly above the cylinder 120, and the piston rod of the pressing cylinder 430 can be connected to the top of the shaft 130. The piston rod of the pressing cylinder 430 performs telescopic movement in the up and down direction. When it is connected to the top of the shaft 130, it can drive the shaft 130 to move downward, thereby pressing down on the shaft 130.
