[0002] Oil cylinder generally refers to hydraulic cylinder, which is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] The hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. The buffer device and the exhaust device depend on the specific application occasion, and the other devices are indispensable. The cylinder is mainly used in machinery and is the most important component of engineering machinery. It is mainly an important core component that provides power for machinery.

[0004] The assembly of the cylinder generally adopts automatic assembly equipment or manual assembly through a clamping platform. Generally, for the assembly of cylinders with low precision requirements, the most common assembly method is manual assembly by staff. This assembly method is suitable for many small and medium-sized traditional manufacturing industries. Its advantages of low assembly cost and low technical requirements are widely used.

[0005] When the oil cylinder is manually assembled, a clamping device is required. Generally, a universal bench vise is used as the clamping device of the oil cylinder. However, the clamping of the bench vise requires manual adjustment, which is extremely labor-intensive and inefficient. In addition, it is easy to loosen or deviate when clamping a round oil cylinder, which has a significant impact on the assembly accuracy. Therefore, special equipment for clamping the oil cylinder is required to assemble the oil cylinder. Although the existing equipment can clamp the oil cylinder effectively and stably, the equipment and the work station are fixed, and it is not suitable for assembly line operations. After processing, it needs to be manually disassembled and transported to the next process, which is time-consuming, labor-intensive and inefficient. Utility Model Content

It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines.

[0024] The hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. The buffer device and the exhaust device depend on the specific application occasion, and the other devices are indispensable. The cylinder is mainly used in machinery and is the most important component of engineering machinery. It is mainly an important core component that provides power for machinery.

[0025] The assembly of the cylinder generally adopts automatic assembly equipment or manual assembly through a clamping platform. Generally, for the assembly of cylinders with low precision requirements, the most common assembly method is manual assembly by staff. This assembly method is suitable for many small and medium-sized traditional manufacturing industries. Its advantages of low assembly cost and low technical requirements are widely used.

[0026] When assembling the oil cylinder manually, a clamping device is required. Generally, a universal bench vise is used as the clamping device of the oil cylinder. However, the clamping of the bench vise requires manual adjustment, which is extremely labor-intensive and inefficient. Moreover, it is easy to loosen or deviate when clamping a round oil cylinder, which has a significant impact on the assembly accuracy. Therefore, a special equipment for clamping the oil cylinder is required to assemble the oil cylinder. Although the existing equipment can effectively and stably clamp the oil cylinder, the equipment and the workstation are fixed, which is not suitable for assembly line operation. After the processing is completed, it needs to be manually disassembled and transported to the next process, which is time-consuming, labor-intensive and inefficient. In order to solve the above problems, this embodiment is provided.

Figure 2 is a schematic top view of the overall structure of this embodiment 1, Figure 3 This is a schematic front view of the overall structure of Example 1. Example 1 is a double-station cylinder assembly platform, including a main frame, which is a frame structure. The top surface is provided with a table plate, and the table plate is provided with a plurality of guide grooves parallel to each other. The guide grooves are provided with an assembly mechanism that can slide freely along the guide grooves. The assembly mechanism includes a guide rail, a center plate is fixed in the middle of the guide rail, and clamping plates are slidably fixed on the guide rails at both ends of the center plate.

[0028] The inner side of the clamping plate is provided with anti-skid grooves to increase the friction with the surface of the oil cylinder and ensure stability during the assembly process. In addition, the clamping plate is also provided with an adjustment mechanism that can be adjusted according to oil cylinders of different sizes to ensure the accuracy and reliability of clamping.

[0029] On both sides of the main frame, a driving device is also provided to drive the assembly mechanism to move on the guide groove. The driving device includes a motor and a transmission mechanism. The motor drives the transmission mechanism, and then drives the assembly mechanism to move back and forth on the guide groove, which facilitates the assembly and disassembly operations of the oil cylinder.

[0030] In addition, the bottom of the main frame is also equipped with support feet to support the entire assembly platform to ensure its stability and load-bearing capacity. The support feet are also equipped with adjustment devices, which can be adjusted in height according to different working environments and needs, making the assembly platform more adaptable to various working environments.

[0031] In summary, the device of this embodiment has the effects of simple structure, convenient operation, stable clamping, and strong adaptability, thereby improving work efficiency and product quality.

[0032] Reference Figure 2 and Figure 3 , Figure 2 is a schematic top view of the overall structure of this embodiment 1, Figure 2 This is a front view schematic diagram of the overall structure of the present embodiment 1, in which: the assembly mechanism also includes a sliding plate, and the sliding plates are two, and the two sliding plates are respectively located on the guide rails at both ends of the center plate, and the two sliding plates are slidably fixed on the guide rails, and the two sliding plates can slide relative to each other along the guide rails.

[0033] Each slide plate is finely machined to ensure a tight fit with the rails. This design allows the slide plates to slide smoothly along the rails without sticking or shaking. At the same time, the anti-slip design on the slide plates also ensures that they can be stably fixed at any position on the rails when needed.

[0034] In addition to the design of the sliding plate itself, the assembly mechanism is also equipped with an advanced control system. This system can accurately control the movement trajectory and speed of the sliding plate to ensure that each step of the assembly process can be carried out in accordance with the preset requirements. At the same time, the control system can also monitor various parameters in the assembly process in real time, such as temperature, pressure, etc., to ensure the stability and reliability of the assembly quality.

The vertical plates are perpendicular to the sliding plates, and a clamping plate is fixed on one side of the vertical plates close to the central plate.

[0036] The inner side of the clamping plate is provided with anti-slip grooves to increase the clamping force on the workpiece and prevent the workpiece from slipping during processing. The length of the clamping plate can be adjusted according to workpieces of different sizes to meet different processing requirements. In addition, an elastic element, such as a spring, is provided between the vertical plate and the clamping plate to ensure that the clamping plate has a certain buffering effect when clamping the workpiece to prevent the workpiece from being damaged due to excessive clamping force.

[0037] Assembly end rollers are also provided on both sides of the sliding plate, and two assembly end rollers are provided on each side of the sliding plate, and the two assembly end rollers are coaxial and installed vertically with the guide groove.

[0038] In addition, the assembly end roller is a thin-walled cylindrical structure made of plastic material. The lightweight design makes the device of this embodiment lighter and more convenient to disassemble and replace. They are connected to the sliding plate through special bearings, so that the roller can rotate freely, reduce friction, and reduce the resistance of the sliding plate during movement. At the same time, the design of the bearing also takes into account the sealing and maintenance convenience, ensuring that the assembly end roller can maintain a good operating state during long-term use.

[0039] In order to further improve the stability and reliability of the sliding plate, an adjustment mechanism is also provided at the axial position of the assembly end roller. Through the adjustment mechanism, the position of the assembly end roller can be fine-tuned.

[0040] Main frame end rollers are also provided on both sides of the table plate, and two main frame end rollers are provided on each side of the table plate, and the two assembly end rollers are coaxially installed and parallel to the assembly end rollers. The main frame end rollers are the same as the assembly end rollers, and are both thin-walled cylindrical structures. In this embodiment, the main frame end rollers and the assembly end rollers are used to fix the cylinder barrel, which is convenient for assembling the oil cylinder at the center plate. Therefore, lightweight materials help save costs and are convenient for disassembly, installation and replacement. In addition, in this embodiment, the two ends of the main frame end rollers and the assembly end rollers are respectively fixed to the table plate and the sliding plate, so that the main frame end rollers and the assembly end rollers can rotate freely on their own axes, and then the cylinder barrel can be loaded and unloaded by utilizing the self-axial rotation of the main frame end rollers and the assembly end rollers, so that the cylinder body with higher quality can utilize the self-axial rotation of the main frame end rollers and the assembly end rollers to achieve lighter loading and unloading, thereby saving workers' physical strength and improving assembly efficiency.

[0041] The opposite ends of the two main frame end rollers and the two assembly end rollers on the same side are respectively provided with a fixed end one and a fixed end two, and the fixed end one and the fixed end two are both truncated cone-shaped, and the fixed end one is composed of the opposite ends of the two main frame end rollers on the same side and the same axis, and the opposite ends of the two main frame end rollers are both truncated cone-shaped, so that the opposite ends of the two main frame end rollers form a funnel shape, and the two formed funnel-shaped truncated cones are the fixed end one, and the composition of the fixed end two is the same as that of the fixed end, and the fixed end one, the fixed end two and the center plate are all located on the same straight line, and the fixed end one and the fixed end two are used to accommodate and limit the fixed cylinder, and the main frame end rollers and the assembly end rollers of different sizes of the fixed end one and the fixed end two can be disassembled and replaced according to the size of the cylinder. In addition, the two assembly-end rollers and the two main-frame-end rollers on the same side can be adjusted for relative displacement along their respective axes, and the coaxial assembly-end rollers or main-frame-end rollers on the same side can be moved coaxially relative to each other, and can move closer or farther away. This movement can adjust the size of fixed end one and fixed end two, and thus can adapt to more cylinders of different sizes within the adjustment range, thereby having a larger adaptation range without disassembling and replacing the assembly-end rollers or the main-frame-end rollers, thereby improving adaptability, improving assembly efficiency, and reducing the frequency of disassembling and replacing the assembly-end rollers or the main-frame-end rollers.

[0042] The two clamping plates respectively located on the two sliding plates are parallel to each other, and the opposite surfaces of the two clamping plates are covered with rubber pads. In this embodiment, the thickness of the rubber pads is 5 mm and has high elasticity. When clamping the cylinder, the clamping plates can fit the outer periphery of the cylinder to avoid slipping and falling off, and have high anti-slip performance.

Clamping plates are slidably fixed on the guide rails at both ends of the center plate. The clamping plates are driven by a cylinder or a motor to fix the oil cylinder for assembly.

[0044] In this embodiment, the clamping plate is connected to the vertical plate as a whole and fixed by bolts. The vertical plate is made of a material with higher strength. The vertical plate and the clamping plate are driven by a motor to move together. The clamping plate is replaced with a matching clamping plate according to the shape of the part to be processed. The surface of the clamping plate is coated with highly elastic anti-slip rubber to improve the anti-slip performance and clamping performance.

The main frame end roller and the assembly end roller can rotate freely on their own axes, and then the cylinder barrel can be loaded and unloaded by utilizing the self-axis rotation of the main frame end roller and the assembly end roller, so that a cylinder body with higher quality can be used by utilizing the main frame end roller The self-axial rotation of the roller and the assembly-end roller realizes lighter loading and unloading, thereby saving workers' physical strength and improving assembly efficiency. The coaxial assembly-end rollers or main frame-end rollers on the same side can perform coaxial relative movement, and can move close to or away from each other. This movement can adjust the size of fixed end one and fixed end two, and thus can adapt to more cylinders of different sizes within the adjustment range, thereby having a larger adaptation range without disassembling and replacing the assembly-end roller or the main frame-end roller, thereby improving adaptability, improving assembly efficiency, and reducing the frequency of disassembling and replacing the assembly-end roller or the main frame-end roller.
