Description

Technical Field

[0001] This utility model relates to the field of assembly precision technology, and in particular to a suspension device for a paint spraying line. Background Technology

[0002] In the industrial manufacturing sector, spray painting lines are widely used to coat the surfaces of parts to achieve purposes such as corrosion protection, aesthetics, or functionality. In automated spray painting production lines, parts to be painted are typically mounted on conveyor mechanisms (such as chains or guide rails) via suspension devices, moving with the spray painting line and passing through spray painting stations.

[0003] Stable suspension and reliable fixation of the parts to be painted are key factors in ensuring painting quality. If the parts to be painted shake, shift, or fall off during the conveying or painting process, it will not only lead to defects such as uneven coating, missed spraying, or overlapping spraying, but may also cause the painting line to stop, workpiece damage, or even safety accidents.

[0004] Traditional suspension and fixing methods often employ hooks, clamps, or magnetic chucks, which have the following problems: Poor adaptability: For workpieces with through holes (such as sheet metal parts, shell-type parts, etc.), conventional suspension methods often cannot achieve center positioning, easily causing the workpiece to tilt or rotate, affecting the painting effect; Insecure fixing: Especially under high-speed movement or the impact of the spray gun airflow, the workpiece is prone to displacement or vibration; Inconvenient assembly and disassembly: Most clamps have complex structures and low clamping efficiency, which is not conducive to improving production cycle time; Easily damages workpieces: The clamping parts may obstruct the painting path or leave contact marks, requiring subsequent processing and increasing costs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the prior art by providing a suspension device for a paint spraying line. This suspension device for a paint spraying line solves the problems of poor adaptability to the parts to be painted, unstable fixation, complex clamping structure, and low clamping efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a suspension device for a paint spraying line, comprising:

[0007] The suspension unit is suspended from the conveyor mechanism;

[0008] The connecting part has its top end connected to the bottom end of the suspension part, the bottom of the connecting part is used to pass through the through hole of the part to be painted, and the bottom of the connecting part is provided with a fixing part;

[0009] A locking element, which is detachably mounted on a fixing part at the bottom of the connecting part;

[0010] When the connecting part passes through the through hole and is locked in place by the locking part and the fixing part, the painted part can be clamped and fixed between the locking part and the hanging part.

[0011] In some embodiments of this application, the outer peripheral wall of the fixing part has threads, and the locking member has a threaded hole that mates with the thread of the fixing part. By the threaded engagement between the fixing part and the locking member, the painted part can be locked or unlocked.

[0012] In some embodiments of this application, the connecting portion has an upper sealing portion that tapers from the top to the bottom; the locking member has a lower sealing portion that tapers from the bottom to the top.

[0013] The locking force applied to the painted part by the locking component causes the upper sealing part to be locked in the upper opening of the through hole, and the lower sealing part to be locked in the lower opening of the through hole.

[0014] In some embodiments of this application, the locking member further has a reinforcing portion connected to the top end of the lower sealing portion, the reinforcing portion extending into the through hole, and the reinforcing portion threadedly engaging with the fixing portion.

[0015] In some embodiments of this application, the suspension part includes a suspension plate with a suspension opening in the middle, and the suspension part is suspended on the conveying mechanism through the suspension opening.

[0016] In some embodiments of this application, the suspension part further includes a support plate connected to the bottom end of the suspension plate, and the suspension plate is fixedly connected to the connecting part through the support plate.

[0017] The present invention has the following beneficial effects: The embodiments of this application, through the cooperation of the locking component and the fixing component, improve the adaptability of the suspension device to the parts to be painted. For example, for parts to be painted with through holes (such as sheet metal parts, housing parts, etc.), it achieves center positioning of the parts to be painted, effectively preventing the parts from tilting or rotating, and ensuring the painting effect. On the other hand, it achieves reliable fixing of the parts to be painted under high-speed movement or the impact of the spray gun airflow, preventing the workpiece from falling off or shaking during conveying or painting. Furthermore, it simplifies the structure of the suspension device, improves clamping efficiency, and helps ensure production cycle time. Simultaneously, it also ensures the structural integrity of the parts to be painted, effectively preventing the clamping parts of the parts from obstructing the painting path or leaving contact marks, thus saving processing costs.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

[0028] In the description of this utility model, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.

[0029] For ease of description below, an XYZ coordinate system is established, with the length direction of the suspension device defined as the X-axis, the width direction as the Y-axis, and the height direction as the Z-axis. It is understood that the coordinate system of the suspension device can be flexibly set according to actual needs; this application only provides an example and should not be considered a specific limitation thereof.

[0030] This application provides a suspension device for a paint spraying line; please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 This is a schematic diagram of the structure connecting the suspension device for the paint spraying line and the workpiece 100 to be painted, as provided in an embodiment of this application. Figure 2 A schematic diagram of the first angle of the suspension device for a paint spraying line provided in an embodiment of this application; Figure 3 for Figure 2 Exploded view; Figure 4This is a schematic diagram of the second angle of the suspension device for a paint spraying line according to an embodiment of this application. The suspension device includes: a suspension part 1, a connecting part 2, and a locking member 3.

[0031] The aforementioned suspension part 1 is suspended on the conveying mechanism.

[0032] The top end of the connecting part 2 is connected to the bottom end of the suspension part 1, the bottom of the connecting part 2 is used to pass through the through hole 101 of the part to be painted 100, and the bottom of the connecting part 2 is provided with a fixing part 22.

[0033] The aforementioned locking member 3 is detachably mounted on the fixing part 22 at the bottom of the connecting part 2.

[0034] When the connecting part 2 passes through the through hole 101 and is locked in place by the locking member 3 and the fixing part 22, the part to be painted 100 can be clamped and fixed between the locking member 3 and the hanging part 1.

[0035] In this way, the embodiments of this application, through the cooperation of the locking member 3 and the fixing part 22, improve the adaptability of the suspension device to the painting part 100. For example, for workpieces with through holes 101 (such as sheet metal parts, shell-type parts, etc.), the center positioning of the part to be painted 100 is achieved, effectively preventing the part to be painted 100 from tilting or rotating, and ensuring the painting effect. On the other hand, under high-speed movement or the impact of the spray gun airflow, the part to be painted 100 is reliably fixed, preventing the part to be painted 100 from falling off or shaking during the conveying or painting process. Furthermore, the structure of the suspension device is simplified, the clamping efficiency is improved, and the production cycle is improved. At the same time, the part to be painted 100 is also prevented from being damaged by the suspension device, ensuring the structural integrity of the part to be painted 100, effectively preventing the clamping part of the part to be painted 100 from blocking the painting path or leaving contact marks, and saving processing costs.

[0036] In some embodiments, the suspension part 1 may include a suspension plate 11. When a plurality of through holes 101 are arranged in parallel on the part to be painted 100, a suspension device needs to be connected to each part to be painted 100 to block the through hole 101. Therefore, the suspension plate 11 is a plate-shaped structure, so that the suspension plates 11 installed on two adjacent through holes 101 are in a parallel state, which can avoid the suspension plates 11 installed in two adjacent through holes 101 from obstructing each other, thus improving the installation efficiency. The plate-shaped structure can reduce the space occupancy rate.

[0037] Furthermore, the conveying mechanism is equipped with hooks, and the suspension plate 11 has a suspension opening 111 in the middle. The suspension device is suspended from the hooks of the conveying mechanism through the suspension opening 111, enabling rapid hoisting and positioning of the part 100 to be painted. When the suspension device is installed on the part 100 to be painted, the production line worker can pass their hand through the suspension opening 111 to grasp the suspension plate 11, facilitating the worker to apply force to tighten the locking component 3. In other examples, the top of the suspension plate 11 may have a suspension ring, and the suspension device may be suspended from the hooks of the conveying mechanism through the suspension ring.

[0038] For example, the shape of the hanging opening 111 includes, but is not limited to, rectangle, square, ellipse, circle or other irregular shape. The embodiments of this application are illustrated by example with a square shape, but this does not constitute a limitation of this application.

[0039] In some embodiments, the suspension part 1 may further include a raised plate 12 connected to the bottom end of the suspension plate 11, and the suspension plate 11 is fixedly connected to the connecting part 2 via the raised plate 12. Furthermore, the dimension of the raised plate 12 in the X-axis direction is smaller than the dimension of the suspension plate 11. The raised plate 12 increases the distance between the suspension plate 11 and the upper surface of the part to be painted 100, avoiding interference between the suspension plate 11 and the part to be painted 100, and improving the space utilization of the suspension device.

[0040] In some examples, the dimension of the raised platform 12 in the X-axis direction can be equal to or slightly larger than the dimension of the upper surface of the connecting part 2. This increases the connection area between the raised platform 12 and the connecting part 2, ensuring the connection strength between the two.

[0041] In some embodiments, the outer peripheral wall of the fixing part 22 of the connecting part 3 has threads, and the locking member 3 has a threaded hole 33 that mates with the thread of the fixing part 22. By the threaded engagement between the fixing part 22 and the locking member 3, the workpiece 100 to be painted can be locked or unlocked. This design features a simple and reliable structure and convenient adjustment; furthermore, the threaded connection provides continuous preload, adapting to workpieces of different thicknesses; the threads are self-locking, making them less prone to loosening under vibration; and operation is simple, requiring no additional tools for manual locking.

[0042] In some embodiments, the connecting portion 2 has an upper sealing portion 21 that tapers from top to bottom. The locking member 3 has a lower sealing portion 31 that tapers from bottom to top.

[0043] The locking force applied to the part to be painted by the locking member 3 causes the upper sealing part 21 to be engaged in the upper opening of the through hole 101 and the lower sealing part 31 to be engaged in the lower opening of the through hole 101.

[0044] In this way, both the upper sealing part 21 and the lower sealing part 31 are tapered designs, meaning that the diameters of the upper sealing part 21 and the lower sealing part 31 are different in each cross-section. This allows the suspension device to be used with through holes 101 of different diameters. The one-to-many design makes the suspension device structurally versatile and adaptable to various specifications of through holes 101, saving processing costs. The upper sealing part 21 can seal the upper end of the through hole 101, and the locking part 3 can seal the lower end of the through hole 101, preventing paint from flowing into the through hole 101. Furthermore, the tapered design facilitates insertion into the through hole 100 and centering. The tapered design can form a seal and limit at the opening of the through hole 101, effectively preventing paint from seeping into the through hole 100, reducing cleaning difficulty and paint waste. The upper sealing part 21 and the lower sealing part 31 clamp the part to be painted 100 in opposite directions, improving clamping accuracy and enhancing fixing stability.

[0045] In some embodiments, the locking member 3 may further have a reinforcing portion 32 connected to the top end of the lower sealing portion 31. The reinforcing portion 32 extends into the through hole 101 and is threadedly engaged with the fixing portion 22. The threaded engagement within the through hole 101 protects the threaded hole from paint contamination. Furthermore, the reinforcing portion 32 increases the thread engagement length between the locking member 3 and the fixing portion 22, improving their connection strength and reinforcing the connection between the locking member 3 and the connecting portion 2. It also saves space occupied by the suspension device in the Z-axis direction, resulting in a compact structure and ease of operation.

[0046] In some embodiments, the suspension part 1 and the connecting part 2 can be integrally molded, that is, the suspension part 1 and the connecting part 2 are a single structural unit. This simplifies the manufacturing process of the suspension device, improves the manufacturing efficiency of the suspension device, reduces the production cost of the suspension device, and also improves the structural strength and durability of the suspension device.

[0047] In other embodiments, the connecting part 2 can be a one-piece molded part. This simplifies the processing technology of the connecting part 2, improves the processing efficiency of the connecting part 2, reduces the production cost of the connecting part 2, and also helps to improve the structural strength and durability of the connecting part 2.

[0048] In some examples, the lower sealing part 31 and the reinforcing part 32 can be integrally molded. This simplifies the processing technology of the locking part 3, improves the processing efficiency of the locking part 3, reduces the production cost of the locking part 3, and also improves the structural strength and durability of the locking part 3.

[0049] The preferred embodiments of this utility model have been described in detail above. However, this utility model is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this utility model, various equivalent modifications can be made to the technical solution of this utility model, and all such equivalent modifications fall within the protection scope of this utility model.
