Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing and manufacturing technology, specifically relating to a simple switching mechanism for skid positioning components in an automotive production line. Background Technology

[0002] Currently, the conveying media in automotive welding production are mainly divided into two types: skids and trolleys. Due to differences in structure and cost, trolleys generally come with a switching mechanism and related accessories to adapt to the needs of flexible production; skids, due to relevant restrictions, are generally vehicle-specific and cannot be switched, and various positioning components (such as positioning pins and positioning blocks) are mounted on the skid using rigid connecting parts.

[0003] This means that different car models, their derivatives, or model improvements and new versions all require additional dedicated skids. This hinders flexible production and storage management, increases costs, and wastes space. Utility Model Content

[0004] The purpose of this utility model is to provide a simple switching mechanism for skid positioning components in an automobile production line, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple switching mechanism for a skid positioning component in an automobile production line, comprising a positioning component, a flipping rod, a flipping pin, and a positioning base. The positioning component is fixed to the top of the flipping rod, and the positioning base is provided with an mounting groove. The bottom of the flipping rod is inserted into the mounting groove and hinged to it through the flipping pin.

[0006] Preferably, the flipping rod is provided with a strip groove, and the flipping pin cooperates with the strip groove.

[0007] Preferably, the positioning base is provided with a pin hole, and the bottom of the flipping rod is provided with a shaft head that mates with the pin hole.

[0008] Preferably, a stop plate is fixed to the side of the positioning base, and a stop groove is provided on one side of the flip pin, with the stop plate cooperating with the stop groove.

[0009] The beneficial effects of this utility model are as follows: Compared with the previous rigid skid structure, this patent has the following beneficial effects and advantages: Compared with the previous rigid connection structure, the structure of this patent has increased flexibility due to its flip-out capability, which can adapt to the need for flexible production of multiple models on a single production line; In terms of weight and size, compared with a rigid welded connection structure with the same effect, there is no significant increase, which reduces the design workload for the actual deployment of this mechanism, and avoids major changes in supporting mechanisms due to excessive changes in weight and size, allowing for quick and easy implementation and saving on design and construction labor costs; In terms of structure, because the number of parts in the entire mechanism is controlled, the structure is simple and easy to manufacture, making production costs controllable.

[0017] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0018] See Figure 1A simple switching mechanism for a skid positioning component in an automotive production line includes a positioning component 1 (taking a supporting positioning block as an example), a flipping rod 2, a flipping pin 3, a positioning base 4, a bolt 5, and a stop plate 6. The positioning component is fixed to the top of the flipping rod. The positioning base has an mounting groove 41, and the bottom of the flipping rod is inserted into the mounting groove and hinged thereto by the flipping pin. The flipping rod has a strip groove 21, and the flipping pin engages with the strip groove. The positioning base has a pin hole 42, and the bottom of the flipping rod has a shaft head 22 that engages with the pin hole. A stop plate is fixed to the side of the positioning base, and a stop groove 31 is provided on one side of the flipping pin; the stop plate engages with the stop groove.

[0019] For structural details of the positioning mechanism, please refer to [link / reference]. Figure 2 In its vertical position, the flipping rod 2 is vertically inserted into the corresponding pin hole of the positioning base 4 via the shaft head, and the flipping pin 3 passes through the elongated hole left in the flipping rod 2, ensuring that it will not accidentally detach from the positioning base 4 in any state. The positioning base 4 is a welded assembly, made of a base plate and a sleeve. The base plate has positioning pin holes and mounting bolt holes, and the sleeve has a groove to mate with the flipping rod 2. In addition, the sleeve has a hole on its side with a flat surface, which mates with the flipping pin 3. The flat surface has a threaded hole to facilitate the installation of the stop plate 6 on the positioning base 4 using bolts 5. At the same time, the flipping pin 3 has a groove with the same width as the stop plate 6, so that the stop plate 6 can be locked in the flipping pin 3 after installation, preventing the flipping pin from rotating or detaching during use. The positioning assembly 1 is assembled on the flipping rod 2 and can take various forms, such as a support block and a three-way adjusting positioning pin. Furthermore, since the flipping rod 2 is inserted into the positioning base 4 through a precision-machined hole, and the positioning base 4 is also provided with a positioning pin hole as described above, the positioning of the positioning component 1 in space can be guaranteed; it can also guarantee the positioning stability during long-term use.

[0020] For details regarding the state and characteristics of the positioning mechanism after it flips, please refer to [link / reference needed]. Figure 3 and Figure 4 Using external force, the flipping rod 2 is pulled out from the corresponding pin hole of the positioning base 4 and rotated and laid down along the side groove until it is flipped into the correct position as shown in the figure. At this time, the flipping rod 2 and its positioning component 1 are controlled by the flipping pin 3 and can only move along the long hole, realizing the flipping switch of the overall structure. When the positioning component 1 is needed, the flipping rod 2 and its positioning component 1 are flipped back in the opposite direction and inserted into the corresponding pin hole of the positioning base 4, thereby restoring the entire mechanism to its original position. Figure 1The state shown achieves the switching purpose. The flip angle of the mechanism and the form of its positioning component should be determined according to the design. In this case, the flip angle is designed to be 120°, and the upper part is a nylon support block. The length of the elongated hole and the height of the positioning base 4 can also be modified according to the actual needs of the parts to achieve adjustable angle.

[0021] In summary, this invention addresses the engineering application problem of transforming the rigid connection between the positioning component and the skid into a reversible flexible connection. The reversible connection is simple to operate, highly practical, energy-efficient, and environmentally friendly. In production, it significantly improves work efficiency and the compatibility of the skid conveyor unit with body panels from different car models, enhancing the flexibility of the production line and reducing unnecessary tooling and personnel costs. From the perspectives of economy, practicality, and ease of operation, this represents a significant advancement in the field of skid conveying for automotive welding lines.

[0022] It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
