Description

Technical Field

[0001] This utility model relates to the field of lifting fixture technology, and in particular to an internal and external spraying lifting fixture. Background Technology

[0002] In the stainless steel cookware manufacturing industry, spray coating plays a crucial role in improving the quality, aesthetics, and durability of cookware. However, current cookware spray coating technologies and related fixtures suffer from numerous limitations that restrict production efficiency and quality improvement.

[0003] In traditional cookware spraying processes, lifting the cookware is mostly done manually or using complex lifting equipment. Manual lifting is not only labor-intensive but also extremely inefficient. Workers need to place each cookware individually into the appropriate spraying position, a process that is time-consuming, labor-intensive, inefficient, and prone to damaging the sprayed surface. While some automated spraying equipment incorporates lifting mechanisms, these mechanisms are often complex, consisting of numerous components, multiple power sources, and intricate control systems. For example, some lifting mechanisms use hydraulic or pneumatic systems, requiring dedicated pump stations or air pumps, resulting in high equipment costs and significant maintenance difficulties. These complex systems have stringent environmental requirements; leaks or component damage lead to high repair costs and long repair times, severely impacting production schedules.

[0004] In addition, most fixtures lack mobility and are difficult to use with automated conveyor lines or multi-station spraying equipment. This results in the need for manual intervention when transferring workpieces between different spraying processes, increasing labor costs and limiting the realization of continuous production.

[0005] Therefore, developing a simple, stable, and compatible internal and external spraying lifting fixture that can be adapted to automated production lines is key to solving the pain points of existing technologies and improving the efficiency and quality of spraying processes.

[0006] The purpose of this utility model is to provide an internal and external spraying lifting fixture to solve the technical problems existing in the prior art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0008] An internal and external spraying lifting fixture includes a base that serves as the basic support for the entire fixture, a sleeve fixedly installed on the upper part of the base, a conical disc and a spring sleeved on the outside of the sleeve, and a lifting rod sleeved inside the sleeve. The conical disc and the lifting rod are connected by a connecting pin. A circular tray is provided on the upper part of the sleeve. The base is installed in the middle of a sliding guide rail with protrusions and can be connected to a power device to drive the entire fixture to slide on the sliding guide rail. The protrusions of the sliding guide rail can act on the conical disc to achieve a lifting effect.

[0009] Preferably, the base is cylindrical, with a fixed limiting plate fixedly installed on its upper part. The fixed limiting plate is circular and can restrict the vertical movement of the base.

[0025] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an internal and external spraying lifting fixture.

[0026] like Figure 1-6As shown, this utility model provides an internal and external spraying lifting fixture, including a base 1 that serves as the basic support for the entire fixture. The base 1 is cylindrical and is installed in the middle of a sliding guide rail 16 with protrusions. It can be connected to a power device to drive the entire fixture to slide laterally on the sliding guide rail 16. A fixed limiting plate 15 is fixedly installed on the upper part of the base 1. The fixed limiting plate 15 is circular and can limit the vertical movement of the base 1. A sleeve 4 is fixedly installed on the upper part of the base 1. The sleeve 4 is a hollow long cylinder. The lower end is fixedly connected to the base 1 and the upper end is fixedly connected to a circular tray 8. A conical plate 2 and a spring 3 are sleeved on its outside, and a lifting rod 6 is sleeved on its inside. A sliding groove 5 is provided on the outer wall of the sleeve 4 to allow the connecting pin to slide up and down between it.

[0027] The conical disk 2 is generally inverted cone shape, with its lower part fixedly connected to the first ring 13 and sleeved on the outside of the sleeve 4. It can move up and down along the outer wall of the sleeve 4. The first ring 13 has a first connecting hole 10 for inserting a connecting pin. The lifting rod 6 is a long cylinder that is sleeved inside the sleeve 4 and can move up and down along the inner wall of the sleeve 4. The upper part of the lifting rod 6 is fixedly mounted with a top plate 7, and the lower part has a third connecting hole 12 for inserting a connecting pin. The conical disk 2 and the lifting rod 6 are connected through the connecting pin. The up and down movement of the conical disk 2 can drive the lifting rod 6 and the top plate 7 to move in the same direction.

[0028] The circular tray 8 is a two-layer stepped tray. A second ring 14 is fixedly connected to the lower part of the circular tray 8. Eight magnet fixing holes 9 are evenly arranged on the circular tray 8 for installing magnets. These magnets can fix the stainless steel sprayed parts to the circular tray 8. The second ring 14 is provided with a second connecting hole 11 for installing fixing bolts. The circular tray 8 is fixedly connected to the upper part of the sleeve 4 by fixing bolts.

[0029] The spring 3 is sleeved on the outside of the sleeve 4, with its upper end installed on the lower part of the second ring 14 and its lower end installed on the upper part of the conical disk 2. When the conical disk 2 moves upward, it can compress the spring 3. After the upward movement ends, the conical disk 2 can be reset by the elastic force of the spring 3.

[0030] In use, the stainless steel cookware to be coated is first placed on the circular tray 8. The magnetic force generated by the magnets installed in the magnetic fixing holes 9 on the circular tray 8 secures the stainless steel workpiece to the tray 8, ensuring that the workpiece will not shift during subsequent coating. The power unit is activated, and the base 1 drives the clamp to move laterally along the sliding guide rail 16, thereby transporting the entire clamp and the fixed workpiece to the designated coating station. After the coating operation is completed, the clamp slides along the sliding guide rail 16 to the protrusion. When the protrusion contacts the conical disc 2 and acts on it, the conical disc 2 moves upward along the outer wall of the sleeve 4. Since the conical disc 2 is connected to the lifting rod 6 via a connecting pin, the upward movement of the conical disc 2 drives the lifting rod 6 to move synchronously upward along the inner wall of the sleeve 4, thereby pushing the top plate 7 upward. The top plate 7 lifts the workpiece, causing it to automatically detach from the circular tray 8 and complete the unloading process. During this process, the upward movement of the conical disc 2 compresses the spring 3, and the spring 3 accumulates elastic potential energy. After unloading, the fixture leaves the protrusion of the sliding guide rail 16. Under the action of the spring force of the spring 3, the conical disk 2 moves downward along the outer wall of the sleeve 4 to reset. At the same time, the lifting rod 6 and the top plate 7 move downward synchronously through the connecting pin, and the workpiece returns to the initial placement position.

[0031] The beneficial effects of this utility model are:

[0032] 1. This utility model can be seamlessly integrated with automated conveyor lines. A power unit drives the base 1, moving the entire fixture along the sliding guide rail 16 to achieve automatic workpiece transport between different workstations. Simultaneously, a lifting mechanism composed of a conical disc 2, lifting rod 6, and other components enables automatic lifting and resetting of workpieces without manual intervention, forming a continuous production process. Compared to the inefficient operation of manual lifting and the risk of production interruptions due to the complex structure of traditional automated equipment, this fixture significantly reduces auxiliary time, substantially improves overall production efficiency, and meets the needs of large-scale mass production.

[0033] 2. The core structure of this utility model consists of only a few components, such as the base 1, sleeve 4, conical disc 2, and lifting rod 6. It lacks complex hydraulic, pneumatic, or precision control systems, resulting in a simple overall structure. This design not only reduces manufacturing difficulty and cost but also decreases the probability of malfunctions. Furthermore, the connection methods for each component are simple, such as the fit between the connecting pin and the slide groove 5, and the direct fitting of the spring 3. When equipment malfunctions, maintenance personnel can quickly locate and replace or repair the faulty component, significantly shortening maintenance time and improving equipment utilization.
