Description

Technical Field

[0001] The utility model relates to the field of micro-tiller manufacturing, and particularly relates to an assembly production line for a micro-tiller. Background Art

[0002] The production and manufacturing process of a micro-tiller mainly includes parts such as a gearbox assembly line, a running-in table, an overall machine assembly, and testing and packaging. During manufacturing, parts are placed on a workbench for assembly, and the workbench needs to be moved to different production line positions for multiple workers to operate simultaneously. After assembly, an overall test is carried out.

[0003] The existing micro-tiller assembly and test production line is divided into multiple workstations, and the equipment at each workstation is different and is used for the assembly of a single part. Parts are manually placed on the equipment for assembly, and after assembly, they are manually moved to the next equipment.

[0004] However, this method has a high labor intensity. The parts of the micro-tiller are relatively heavy, especially in the later stage of assembly, manual movement is very laborious and the efficiency is low. Summary of the Utility Model

[0005] The utility model aims to provide an assembly production line for a micro-tiller to solve the problems of high manual labor intensity and low efficiency of the existing assembly production line.

[0006] To achieve the above object, the utility model provides an assembly production line for a micro-tiller, which includes an annular slide rail. A conveying chain is arranged in the annular slide rail. A plurality of freely movable workbenches are arranged on the annular slide rail. A plurality of universal wheels are installed below the workbench. Support blocks are installed on both sides of the workbench. A sleeve is fixed below the workbench. A connecting rod is slidably arranged in the sleeve, and the other end of the connecting rod is fixedly connected with the conveying chain. A rotating shaft is arranged vertically above the workbench, and a rotating plate is fixed at the upper end of the rotating shaft. A plurality of support platforms are arranged in a row on both sides of the upper surface of the annular slide rail. Two hydraulic rods are arranged on the support platform, and a support plate is fixed at the piston rod of the hydraulic rod.

[0007] The working principle of the technical solution is as follows: The annular slide rail is used to provide a moving area for the station wagon. A conveying chain is arranged at the middle position, and a plurality of driving components are arranged inside the conveying chain. The driving components include motors and sprockets. The diameter of the sprocket is smaller than the distance between the connecting rod and the universal wheel to avoid blocking the passage of the universal wheel. After starting the motor, the sprocket is driven to rotate by the motor, and then the conveying chain is driven to move. The connecting rod is arranged in the sleeve under the station wagon and can only slide up and down. It is used to connect the station wagon and the conveying chain. When the conveying chain rotates, the station wagon is driven to move through the connecting rod and the sleeve. During normal operation, the weight of the station wagon is distributed on a plurality of universal wheels, and the conveying chain and the connecting rod are only used to drive its movement. When the station wagon moves to the support platform, the support blocks on both sides of it move above the support platform. The hydraulic rod is started to push up the support plate, and then the station wagon is lifted up by a certain height, making the universal wheels suspended and no longer supporting the station wagon, which can improve the stability of the station wagon. The connecting rod slides in the sleeve so that the conveying chain will not be pulled when the station wagon is lifted up. During assembly, the rotating plate can be horizontally rotated through the rotating shaft to facilitate adjusting the assembly angle. After the assembly is completed, the hydraulic rod retracts, and the universal wheels contact the ground again to form a support for the station wagon. During specific assembly production, various assembly equipment, grinding equipment, etc. can be installed on the annular slide rail above or on the side close to the support platform through brackets, leaving only the moving space for the station wagon. Then, when the conveying chain runs, it drives the station wagon to move. The station wagon is used to transport parts and is gradually assembled when passing through each support platform, forming an assembly line in a pipeline manner, avoiding manual handling or reducing the handling distance.

[0008] Compared with the prior art, the beneficial effects of this application are as follows: 1) During normal operation, the universal wheels provide support and moving ability. After reaching the support platform, the station wagon is lifted by the hydraulic rod and the support plate, which can effectively improve the stability of the station wagon and avoid accidental movement of the universal wheels during assembly.

[0009] 2) It can avoid manually transporting parts to the equipment for assembly, or effectively reduce the handling distance, reduce the labor intensity, and improve the assembly efficiency.

[0010] 3) The rotating plate can rotate flexibly to adjust the angle facing the worker during assembly, avoiding adjusting the angles of the assembled parts, which can be more labor-saving.

[0011] 4) The station wagon can move up and down through the hydraulic rod, which can make it more convenient for operators of different heights to perform assembly.

[0012] Preferably, it further includes a protective plate which is fixed to the side of the support table.

[0013] Beneficial effects: The protective plate is used to block the sides of the workbench cart and the hydraulic rod, preventing the support plate from pinching the operator's limbs or clothes when it moves upward, thus avoiding safety accidents.

[0014] Preferably, a guiding slide rail is vertically fixed on the protective plate, and the guiding slide rail is slidably connected to the support plate.

[0015] Beneficial effects: The guiding slide rail can limit the movement trajectory of the support plate and improve the stability of the support plate.

[0016] Preferably, it further includes a bolt. The rotating plate is provided with a plurality of jacks in the vertical direction, and the workbench cart is provided with fixing holes in the vertical direction; when the jacks and the fixing holes correspond, the rotating plate and the workbench cart can be fixed by the bolt.

[0017] Beneficial effects: After adjusting the angle of the rotating plate, the rotating plate can be quickly fixed by the bolt, preventing it from rotating during assembly.

[0018] Preferably, a fixing table and a plurality of support rods are fixed above the rotating plate. The fixing table is fixed at the central position of the upper surface of the rotating plate; the plurality of support rods are arranged outside the fixing table.

[0019] Beneficial effects: The fixing table is concave, used to limit the main body of the parts of the micro-tiller. The support rods are located outside the fixing table, used to assist in fixing various parts.

[0020] Preferably, it further includes a plurality of straps and a plurality of fixing buckles. The plurality of straps are arranged on the plurality of support rods; the plurality of fixing buckles are fixed on the plurality of support rods.

[0021] Beneficial effects: The straps are wound around the parts of the micro-tiller or can be used to bind parts and accessories such as drive shafts and connecting wires, and then pass through the fixing buckles, which can further improve the fixing of the parts of the micro-tiller and facilitate assembly.
