Description
Technical Field
[0001] This utility model relates to the field of vehicle body conversion technology, and in particular to a vehicle body floor conversion device. Background Technology
[0002] In the automotive manufacturing industry, the automated final assembly line is a crucial link in the automotive manufacturing process. It requires various conveying and transfer equipment to move and transfer automotive parts and vehicles. The body floor transfer equipment is paramount in this process. Existing body floor transfer equipment consists of a lateral trolley with an eccentric lifting structure and the body floor mounted on it, driven along a track. This equipment has significant drawbacks: it requires a large footprint, lacks precise positioning, is difficult to operate, and poses safety risks.
[0003] CN201821212686.0 discloses a vehicle body transfer device, including a transfer fork mechanism, a telescopic mechanism for driving the transfer fork mechanism to extend and retract, a lifting drive mechanism for driving the telescopic mechanism to rise and fall, and a horizontal moving mechanism for driving the lifting drive mechanism to move horizontally. The horizontal moving mechanism is connected to the lifting drive mechanism, the lifting drive mechanism is connected to the telescopic mechanism, and the telescopic mechanism is connected to the transfer fork mechanism. This vehicle body transfer device has a compact structure, is easy to install and disassemble, and the installation process does not require modification to any equipment on the production line, thus not delaying normal production. The forward and backward movement, up and down lifting, and horizontal movement of the transfer fork mechanism are independently controlled, ensuring safe and accurate movement in each direction and facilitating control. However, the motion control coordination is insufficient, the space occupation is large, and the positioning accuracy is insufficient. Utility Model Content
[0004] The purpose of this utility model is to overcome the defects of the existing technology and provide an automobile body floor transfer device with high space utilization, high degree of automation and precise positioning.
[0005] This invention is fully automated, achieved through a combination of a transfer fork and an eccentric lifting mechanism. It occupies a small area, enables precise positioning, and provides reliable technical support for subsequent process connections. It significantly improves work efficiency and safety, and enhances accuracy. It not only reduces the factory's fixed asset investment costs but also increases production efficiency and capacity, and enables highly repetitive, low-skill tasks.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] An automotive body floor adapter includes:
[0008] A transfer fork assembly is used to carry and transfer the vehicle body floor; the transfer fork assembly is driven to move by a transfer fork drive assembly;
[0009] An eccentric lifting assembly, connected to a transfer fork assembly, is used to lift the vehicle's floor.
[0010] The sprocket and chain drive assembly drives the eccentric lifting assembly to rise and fall, thereby driving the transfer fork assembly to move; the sprocket and chain drive assembly is driven by the sprocket and chain drive assembly.
[0011] The electrical control components are communicatively connected to the transfer fork drive assembly and the sprocket and chain drive assembly, respectively; the automatic transfer of the vehicle floor is achieved through the coordinated action of the transfer fork assembly and the eccentric lifting assembly.
[0012] Furthermore, it also includes a guide component to guide the movement direction of the transfer fork assembly and ensure movement accuracy.
[0013] Furthermore, it also includes sensor components for detecting the position of the transfer fork assembly and the positioning status of the vehicle chassis floor.
[0014] Furthermore, it also includes maintenance supports, used for supporting and fixing equipment during maintenance.
[0015] Furthermore, it also includes framework components, which are used to support and secure the various functional components.
[0016] Furthermore, the eccentric lifting assembly includes: an eccentric wheel, a connecting rod, and a support frame; the sprocket and chain drive assembly transmits power to the eccentric wheel, the rotation of the eccentric wheel drives the connecting rod to move, and the connecting rod pushes the transfer fork assembly to perform lifting and lowering movements.
[0017] Furthermore, the transfer fork drive assembly is a drive motor.
[0018] Furthermore, the transfer fork assembly includes at least two pairs of parallel fork arms, with anti-slip rubber pads at the ends of the fork arms to increase friction with the vehicle floor.
[0019] Furthermore, the sprocket and chain drive assembly adopts a double-row chain drive structure, symmetrically arranged on both sides and connected in the middle by a rigid drive shaft, to ensure that the eccentric lifting assembly lifts and lowers synchronously on both sides and avoids uneven loading.
[0020] Furthermore, the frame assembly adopts a modular welded steel structure and is equipped with adjustable anchor bolts at the bottom to facilitate the installation and positioning of the equipment.
[0021] The workflow is as follows:
[0022] When the upstream conveyor line transports the vehicle body floor to the transfer station, the sensor assembly detects that the vehicle body floor is in place, the electrical control assembly issues a command, the sprocket and chain drive assembly starts, the sprocket and chain transmission assembly drives the eccentric lifting assembly to move, and the transfer fork assembly rises to the receiving height.
[0023] The transfer fork assembly is precisely moved to the underside of the vehicle body floor. The transfer fork drive assembly is activated, pushing the transfer fork assembly to move along the guide assembly. The fork arm is accurately inserted into the support point under the vehicle body floor. After the sensor assembly confirms that the fork arm is in place, the eccentric lifting assembly slightly raises, causing the vehicle body floor to detach from the conveyor line.
[0024] After the vehicle chassis is stably supported, the electrical control components coordinate the transfer fork drive components and the sprocket and chain drive components. While the transfer fork components move horizontally, the eccentric lifting components rise and fall according to a preset trajectory. The frame components provide stable support to ensure smooth movement. The entire process is monitored in real time by the sensor components.
[0025] When the transfer fork assembly approaches the target position, the system switches to precise positioning mode, the speed decreases, the guide assembly's limit device activates, the sensor assembly confirms the final position, and the eccentric lifting assembly adjusts to the target height.
[0026] Upon reaching the target position, the eccentric lifting assembly slowly descends, placing the vehicle floorboard onto the downstream equipment. The transfer fork assembly retracts slightly to ensure the fork arms are completely detached from the vehicle floorboard. The sensor assembly confirms the release is complete, and the transfer fork assembly returns to its initial position, ready for the next transfer.
[0027] Compared with the prior art, the present invention has the following advantages:
[0028] (1) High space utilization. This utility model reduces the floor space occupied by the compact design of the transfer fork assembly and the eccentric lifting assembly compared with the traditional transverse trolley transfer equipment; the frame assembly adopts a three-dimensional layout, making full use of vertical space, which is particularly suitable for modern automobile production lines with limited space.
[0029] (2) High degree of automation. The electrical control components realize intelligent coordinated control of the transfer fork drive components and the sprocket and chain drive components, requiring no manual intervention. The sensor components monitor the position status of each component in real time, automatically completing the entire process of gripping, transferring and releasing the vehicle chassis.
[0030] (3) Precise positioning. The equipment is equipped with high-precision sensor components and guide components, combined with a servo control system, to achieve high positioning accuracy. The double-sided synchronous design of the sprocket and chain drive components effectively eliminates the off-center load problem of traditional single-sided drive, ensuring a smooth and precise lifting process.
