Description

Technical Field

[0001] This utility model belongs to the field of bicycle manufacturing, and specifically relates to a bicycle ring pre-assembly device. Background Technology

[0002] In traditional bicycle parts assembly production, after the parts are processed, the main body is usually pre-assembled, and then workers move it to the front of the assembly line to continue assembling the remaining parts. However, the above method has many problems.

[0003] First, manual handling of parts is inefficient and prone to errors such as missing or damaged parts and incorrect assembly sequence, leading to unstable assembly quality. Second, the circulation and storage of parts require a large amount of space and are easily damaged due to collisions or drops during storage and circulation, increasing production costs and reducing production efficiency. At the same time, if the assembly line changes product models or adjusts production plans, it is difficult to quickly adjust the storage location and circulation path of parts, resulting in poor flexibility.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a bicycle ring pre-assembly device. The chain plate conveyor design realizes the automatic and continuous conveying of pre-assembled semi-finished products, accurately conveying the semi-finished products to each workstation for assembly line workers to assemble, improving the efficiency of parts circulation, reducing labor intensity, and improving production efficiency; at the same time, through the design of guide rails and several guide wheels, the chain plate is prevented from tilting when subjected to external forces, which could lead to chain derailment or jamming, thus ensuring the stability of equipment operation.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a bicycle ring-shaped pre-installation device, including a mounting frame, a set of I-beams, a drive motor, a set of chains, several chain plates, a limiting and guiding assembly, and a pre-installation support assembly; the I-beams are respectively located at both ends of the mounting frame; the drive motor is located on the mounting frame; the drive motor is connected to the rotating shaft of the I-beams and is located beside the I-beams; the chains are respectively located on the rotating wheels of the two I-beams and are driven by the rotating wheels of the I-beams to move; the chain plates are located between the upper and lower sets of chains and are connected to the chains by bolts; the limiting and guiding assembly is located between the chain plates and the mounting frame to realize the limiting and guiding of the chain plates; the pre-installation support assembly is located on the side of the chain plates away from the mounting frame to realize the support of the product. The limit guide assembly is installed between the chain plate and the mounting frame, which effectively restricts the movement direction of the chain plate, prevents the chain plate from deviating or shaking during the conveying process, improves the stability of the conveying, and extends the service life of the chain plate and chain. At the same time, the design of the chain plate conveyor realizes the automatic and continuous conveying of pre-assembled semi-finished products, accurately conveying the semi-finished products to each workstation for assembly line workers to assemble, thereby improving production efficiency.

[0007] Furthermore, the limiting and guiding assembly includes two sets of guide rails and several guide wheels; the guide rails have upper and lower layers, respectively located on both sides of the mounting frame; the guide wheels are located on the side of the chain plate near the mounting frame and cooperate with the guide rails to complete the guidance. The guide rails have upper and lower layers, providing support for the chain plate during movement, and cooperating with the mounting frame to distribute the force on the chain plate, preventing the chain plate from tilting when subjected to external forces.

[0008] Furthermore, the guide wheels are evenly distributed on several chain plates. The guide wheels provide uniform force to the chain plates, ensuring stability during equipment operation.

[0009] Furthermore, the pre-assembled support assembly includes several sets of Y-shaped brackets and triangular brackets; the Y-shaped brackets and triangular brackets are arranged sequentially from top to bottom on the side of the chain plate away from the mounting bracket. The Y-shaped brackets and triangular brackets provide stable support for the bicycle body, ensuring that it can be transported to various workstations for assembly.

[0010] Furthermore, a Y-shaped bracket and a triangular bracket are provided on the opposite side of the chain plate with the guide wheel. The Y-shaped bracket and the triangular bracket support the main body of the bicycle, which has a large weight. The guide wheel on the opposite side of this chain plate effectively distributes the weight, preventing the chain plate from tilting and affecting production efficiency.

[0011] Furthermore, both the Y-shaped bracket and the triangular bracket are horizontally positioned. This horizontal positioning ensures that the bicycle body placed on them will not slip, guaranteeing stability during transport.

[0012] Furthermore, a component placement platform is provided above the mounting frame. This platform is used to place components to be assembled, facilitating assembly by workers at various workstations on the production line.

[0013] Furthermore, several feet are provided below the mounting bracket. The feet provide support for the stability of the entire device.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0015] 1. This utility model relates to a bicycle ring pre-assembly device. The chain plate conveyor design realizes the automatic and continuous conveying of pre-assembled semi-finished products, accurately conveying the semi-finished products to each workstation for assembly line workers to assemble, improving the efficiency of parts circulation, reducing labor intensity, and improving production efficiency.

[0016] 2. This utility model provides a bicycle ring pre-assembly device. Through the design of guide rails and several guide wheels, it avoids the chain plate from tilting when subjected to external forces, which could lead to chain derailment or jamming, thus ensuring the stability of the equipment operation.
