Description

Technical Field

[0001] This utility model mainly relates to the field of automotive parts technology, specifically a multi-functional fixture for processing metal automotive parts. Background Technology

[0002] Automotive parts processing refers to the process of transforming raw materials such as metals and plastics into parts that meet automotive assembly standards through a series of processes including casting, forging, stamping, welding, machining, and surface treatment. It covers multiple categories such as engine parts, chassis components, body trim parts, and interior parts. Among them, a large number of small-sized automotive parts (such as small connecting rods, micro frame parts, and irregularly shaped small decorative parts) are the core links in the automotive manufacturing industry chain. In the automotive parts processing flow, the painting process is a key surface treatment step. It mainly refers to the uniform spraying of paint onto the surface of the workpiece through specific processes to form a coating with protective, decorative, or special functions (such as high temperature resistance and corrosion resistance). This not only improves the appearance and texture of automotive parts but also enhances their anti-aging and anti-wear capabilities, extending the service life of the parts.

[0003] Currently, the mainstream method for painting these small parts in the industry is manual handheld spray gun operation. Operators usually place a few small parts directly on a regular spray paint tray and then move the handheld spray gun back and forth to spray and cover the surface of the parts. However, this traditional painting mode for small parts has many core defects. As the variety of small parts increases, the lack of a special mold head for fixing the small parts results in extremely poor clamping stability. Because the small parts are small and light, and are placed directly on a regular spray paint tray without a specially adapted mold head for positioning and fixing, when the operator holds the spray gun back and forth during the painting process, airflow disturbance or slight collision can easily cause the small parts to shift or tip over, seriously affecting the painting quality. Utility Model Content

[0004] This utility model addresses the problem of overly simplistic solutions in existing technologies by providing a multi-functional fixture for processing metal automotive parts. This fixture solves the problem mentioned in the background that the small size and light weight of the parts, when placed directly on a standard paint spraying tray, make them susceptible to displacement or tipping due to airflow disturbances or minor collisions during painting, severely affecting the quality of the paint application.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A multi-functional fixture for processing metal automotive parts includes a base, a turntable rotatably connected to the top of the base, and a connector fixedly connected to the top of the turntable. The connector can selectively mount a first mold head, a second mold head, or a third mold head.

[0006] Furthermore, the top of the base is provided with a rotating mounting structure, and the turntable is mounted on the top axis of the base through the rotating mounting structure to form a horizontal rotating structure. The rotating mounting structure is a bearing assembly or a shaft assembly.

[0007] Furthermore, the central region of the turntable has several slots spaced at equal angles along the circumference, and multiple connectors are fixed to the surface of the turntable at equal angles.

[0008] Furthermore, the first mold head includes a square base made of metal and a strip-shaped structure fixed at the center of the surface of the square base. The strip-shaped structure is made of high-hardness plastic and has rounded chamfers at the four corners. The bottom of the square base of the first mold head has a slot for insertion into the top of the connector.

[0009] Furthermore, the second mold head is made of metal and has an overall frame structure with a horizontally extending rod and two side uprights. The two side uprights are arranged opposite each other, and a snap-fit ​​groove is opened in the middle area of ​​each upright along its height direction. At the bottom of the strip-shaped metal insertion part at the bottom of the second mold head, a slot is opened to cooperate with the top of the connector.

[0010] Furthermore, the third mold head is made of high-hardness plastic material, and its outer periphery is surrounded by smooth curves to form a closed contour with unequal lengths of major and minor axes, and a hollow cavity with the same shape as its outer contour is opened inside the shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This multi-functional fixture for machining metal automotive parts features three structurally differentiated die heads, adaptable to various types of small automotive parts to meet diverse processing needs. The first die head, with a square metal base and a high-hardness plastic strip structure, is suitable for square column workpieces with grooves and hollow interiors. It provides stable positioning through insertion and protects the workpiece surface from scratches thanks to the plastic material and its curved shape. The second die head uses a metal frame structure, with horizontal extension rods and interlocking slots on both side plates to create a three-dimensional fixation for small frame-like workpieces, ensuring no blind spots during processing. The third die head, with a high-hardness plastic irregular-shaped shell and hollow cavity, is suitable for small decorative shells, irregularly shaped sensor shells, and other specially curved contour parts. Furthermore, each die head can be customized according to the specifications of the processed product, and the mating interface between the die head and the workpiece is slightly larger than the workpiece's mating area, facilitating loading and unloading while further enhancing the adaptability to different parts. This effectively prevents workpiece displacement during processing, ensures uniform paint coverage during painting, and improves processing quality.

[0012] 2. The top of the base uses a bearing assembly or a rotating shaft assembly as a rotating mounting structure. The turntable is installed at the center of the shaft to form a horizontal rotating structure, which allows the turntable to rotate smoothly and uniformly around the base, avoiding jamming and offset. This ensures that the mold head and workpiece on the turntable maintain a stable rotation trajectory, so that all surfaces of the workpiece are evenly contacted with the paint, eliminating the problem of excessive paint thickness or missed areas. The turntable has slots at equal angles along the circumference in the middle, which can reduce the accumulation and residue of paint on the turntable surface during painting. At the same time, multiple connectors are fixed to the turntable surface at equal angles, which can be quickly adapted and installed with the slots or plugs at the bottom of each mold head. This ensures that the mold head is installed firmly and allows for quick switching between different mold heads, supporting the simultaneous or batch processing of multiple types of accessories.

[0016] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0017] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Please refer to the appendix carefully. Figure 1-4A multi-functional fixture for processing metal automotive parts includes a base 1, a turntable 2 rotatably connected to the top of the base 1, and a connector 3 fixedly connected to the top of the turntable 2. The connector 3 can selectively install a first mold head 4, a second mold head 5, or a third mold head 6.

[0019] In this embodiment, as Figure 1 and Figure 2 As shown, the top of the base 1 is provided with a rotating mounting structure. The turntable 2 is mounted on the top axis of the base 1 through the rotating mounting structure, forming a horizontal rotating structure. The rotating mounting structure is a bearing assembly or a shaft assembly.

[0020] With the above structure, the top of the base 1 uses a bearing assembly or a rotating shaft assembly as a rotating mounting structure, and the turntable 2 is installed at the top axis to form a horizontal rotating structure. This allows the turntable 2 to rotate smoothly and uniformly around the base 1, ensuring that the mold heads installed on the turntable 2 and the workpieces held on it always maintain a stable rotation trajectory. This allows the workpieces to be evenly contacted with the paint on each surface during the painting process, avoiding situations where the paint is too thick in some areas or there are missed areas.

[0021] In this embodiment, as Figure 1 and Figure 2 As shown, in the central area of ​​the turntable 2, several slots are provided at equal angular intervals along the circumference, and multiple connectors 3 are fixed to the surface of the turntable 2 at equal angular intervals.

[0022] With the above structure, several slots are opened at equal angles along the circumference in the central area of ​​the turntable 2, which can reduce the accumulation and residue of paint on the surface of the turntable 2 during the painting process. The multiple equally spaced connectors 3 can be quickly adapted and installed to the slots or plugs at the bottom of the three mold heads. This unified and convenient installation method not only ensures the stability of each mold head after installation, but also enables the rapid switching of different mold heads. It can simultaneously or in batches process various types of small car parts for painting, thus improving processing efficiency.

[0023] In this embodiment, as Figure 3 and Figure 4 As shown, the first mold head 4 includes a square base made of metal and a strip-shaped structure fixed at the center of the surface of the square base. The strip-shaped structure is made of high-hardness plastic and has rounded chamfers at the four corners. The bottom of the square base of the first mold head 4 has a slot for insertion into the top of the connector head 3.

[0024] The second mold head 5 is made of metal and has a frame structure with a horizontal extension rod and two side uprights. The two side uprights are arranged opposite each other, and the middle area of ​​each upright is provided with a snap-fit ​​groove along its height direction. The bottom of the strip metal insertion part at the bottom of the second mold head 5 is provided with a slot that matches the top of the connector 3.

[0025] The third mold head 6 is made of high-hardness plastic. Its outer perimeter is surrounded by smooth curves to form a closed contour with unequal lengths of major and minor axes. A hollow cavity with the same shape as the outer contour is opened inside the shell.

[0026] Through the above structure, three different mold heads can be matched with different types of small automotive parts. The square base and high-hardness plastic strip structure of the first mold head 4 are suitable for square column workpieces with grooves and hollow interiors. It can not only stably insert and position, but also protect the workpiece surface through plastic material and arc design. The metal frame structure of the second mold head 5 is suitable for small frame-type workpieces, and can form a three-dimensional fixation from the sides and bottom. There are many automotive parts with special curved contours, such as small decorative shells and irregularly shaped sensor shells. The shape of the third mold head 6 is designed according to these special-shaped parts, which can provide a precise installation base and stable clamping guarantee for these parts. This multi-mold head adaptation structure enables various small automotive parts to achieve stable clamping in the painting process, effectively avoids displacement during processing, ensures that the paint evenly covers the workpiece surface, reduces scratch damage to the workpiece surface, improves painting quality and processing efficiency, and meets the processing needs of automotive parts with different structures.

[0027] The specific operating procedure of this utility model is as follows: When using this multi-functional fixture for machining small-sized metal automotive parts, the corresponding die head should be selected according to the structural type of the part to be machined, and the following procedure should be followed: When processing a square column with a groove and a hollow internal structure, the first mold head 4 is used. The operator first aligns the groove at the bottom of the first mold head 4 with the connector head 3 and inserts it vertically downwards until it is fully engaged, ensuring that the mold head is stable and not loose. Then, the square column with the groove is aligned with the long strip structure on the surface of the first mold head 4 through its own groove and fitted along the length of the long strip structure. The initial positioning of the workpiece is achieved by the insertion and cooperation of the two. At the same time, the bottom of the workpiece is attached to the square base to further limit lateral displacement. During the processing, the operator can hold the paint gun in one hand and aim it at the surface of the workpiece, while turning the turntable 2 with the other hand to drive the workpiece to rotate at a uniform speed to ensure that the paint is evenly covered.

[0028] For small frame-type workpieces, a second mold head 5 is required. The second mold head 5 is made of metal. The operator first aligns the slot at the bottom of the second mold head 5 with the connector head 3 and inserts it to ensure that the two side plates are symmetrical and the opening of the snap-fit ​​groove is facing upward. Then, the two side edges of the small frame-type workpiece are aligned with the snap-fit ​​groove of the side plate and slowly inserted along the height direction of the snap-fit ​​groove until the bottom of the workpiece contacts the horizontal extension rod. Through the limiting of the snap-fit ​​groove and the support of the horizontal extension rod, the workpiece is stably clamped, and the hollow area of ​​the frame-type workpiece is unobstructed. Similarly, during subsequent processing, the operator holds a spray gun in one hand to spray the surface of the workpiece and the hollow edges, and can flexibly rotate the turntable 2 with the other hand to ensure that all surfaces are evenly painted.

[0029] The third mold head 6 is used to install and connect automotive parts whose shape matches the closed protrusion structure at its opening, such as small shell parts commonly used in automotive parts, small wiring protection shells in the engine compartment, etc. During operation, first connect the bottom of the third mold head 6 with the connector 3 at the top of the turntable 2 and install it firmly, ensuring that the closed protrusion at its opening faces the processing direction. Then, align the automotive part to be processed with the closed protrusion at the opening of the third mold head 6, and use the unique edge part of the closed protrusion to achieve snap-fit, and install it on the top of the third mold head 6. During the processing stage, after starting the paint gun, the operator holds the paint gun with one hand to spray evenly on the exposed surface of the part, and slowly rotates the turntable 2 with the other hand, so that the part rotates at a uniform speed around the axis of the base 1 with the third mold head 6, ensuring that all parts such as the curved surface and edges of the part can be evenly covered with paint, avoiding paint dead corners, thereby achieving comprehensive processing of the automotive part.

[0030] It should be noted that the structures of the first mold head 4, the second mold head 5, and the third mold head 6 can be customized to fit the specific specifications of the processed products. In order to facilitate the loading and unloading of workpieces, the fitting port between the mold head and the workpiece should be slightly larger than the joint of the workpiece. This allows the workpiece to be loaded into or removed from the mold head more easily, so as to meet the processing requirements of metal automotive parts of different specifications and give full play to the multi-functional adaptability of the fixture.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
