Description

Technical Field

[0001] This utility model relates to the field of hanging racks, and in particular to a coating spraying hanger. Background Technology

[0002] As a key process equipment in industrial production, spraying fixtures are mainly used to accurately position and reliably fix sprayed parts during surface treatment (such as spraying, electroplating, etc.). The performance of these tools directly affects the coating uniformity, process efficiency and product quality.

[0003] Traditional spraying fixtures generally adopt a rigid connection design. Their structural characteristics are mainly manifested in the following ways: the main body of the fixture and the support frame are rigidly connected by welding or bolts; the parts to be sprayed maintain a fixed spatial posture during the process, which means that the parts to be sprayed cannot be adjusted to adapt their angle according to the spraying requirements. This leads to quality problems such as uneven coating thickness and insufficient coverage of masking areas on complex curved workpieces. Secondly, when multiple workpieces are loaded on the fixture at the same time, the traditional rotating mechanism cannot achieve selective rotation. That is, all workpieces must rotate synchronously, even if some parts of some workpieces do not need to be sprayed. This results in energy waste and unnecessary coating contamination on the surface of non-sprayed workpieces. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a coating spraying fixture that solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a coating spraying hanger, comprising a frame composed of multiple independent supports, each of which is equipped with a hanger, and at least one support is provided with a rotating component, the rotating component having a connecting part, one end of which is connected to the hanger, so that the hanger can rotate with the rotating component.

[0006] Furthermore, a rotatable disc is connected to the lower end of the frame.

[0007] Furthermore, the hanger includes a container and a cover, with the connecting part connected to the cover.

[0008] Furthermore, a positioning block is provided between the bracket and the hanger, and multiple through holes are provided radially on the bracket for the positioning block to be fixed by a knob.

[0009] Furthermore, one side of the receiving device is provided with a recessed / protruding locking portion, and the positioning block is connected to the locking portion.

[0010] Furthermore, there are at least two rotating components, located on the same horizontal plane, and the two rotating components are connected by a rod.

[0011] Furthermore, the rotating assembly includes a support block mounted on a bracket, a rotatable rotating rod mounted on the support block, a rod body connected to the rotating rod, and a connecting part connected to the rod body.

[0012] Furthermore, a dust cover is fitted onto the bearing block, and the dust cover has an opening for the rotation trajectory of the rod.

[0013] Furthermore, the independent support includes a first rod, a second rod, and a third rod. The corresponding hangers set on each rod are divided into a first part, a second part, and a third part, and the rotating component is located on the first part.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, during the spraying process, the rotating component can be controlled to drive the connecting part to rotate the fixture according to the actual needs of the fixture on the bracket (such as whether the workpiece needs to be sprayed, the spraying angle requirements, etc.). This selective rotation mechanism can accurately control the spraying range, thereby optimizing the spraying uniformity, reducing paint waste, and improving the overall process efficiency.

Detailed Implementation

[0020] Please refer to Figure 1-3As shown, this illustrates the specific structure of a preferred first embodiment of the present invention, which is a coating spraying fixture. It includes a frame 10 composed of multiple independent supports 1, each support 1 having a fixture 20 mounted on it. At least one support 1 has a rotating component 30, which has a connecting portion 31. One end of the connecting portion 31 is connected to the fixture 20, allowing the fixture 20 to rotate with the rotating component 30. During the spraying process, the rotating component 30 can be controlled to drive the connecting portion 31 to rotate the fixture 20 according to the actual needs of the fixture 20 on the support 1 (such as whether the workpiece needs spraying, the required spraying angle, etc.). This selective rotation mechanism can precisely control the spraying range, thereby optimizing spraying uniformity, reducing paint waste, and improving overall process efficiency.

[0021] For example, a rotatable disc 40 is connected to the lower end of the frame 10. The disc 40 can rotate under the drive of the drive cylinder, thereby driving multiple supports 1 on the frame 10 to rotate synchronously, so that the workpiece on the hanger 20 can be evenly covered during the spraying process.

[0022] For example, the hanger 20 includes a receiving device 21 and a cover plate 22, with a connecting part 31 connected to the cover plate 22. The connecting part 31 is detachable and connected to the upper surface of the cover plate 22 by screws. This connection method allows the rotating component 30 to rotate synchronously with the connecting part 31 and the connected cover plate 22 when the rotating component 30 rotates under the drive cylinder or human torsion. During the spraying operation, as the rotating component 30 continues to operate, the cover plate 22 can open and close according to a preset trajectory: when the cover plate 22 rotates to the closed position, it can form a cover with the receiving device 21, ensuring that the exposed area of ​​the workpiece can be uniformly covered by the spray. On the other hand, it can effectively shield and protect specific parts of the workpiece (such as threaded holes, assembly surfaces, and other finely machined areas), thereby significantly improving the quality stability of the spraying process and reducing the workload of subsequent cleaning processes.

[0023] For example, a positioning block 50 is provided between the bracket 1 and the hanger 20, and the bracket 1 has multiple through holes 60 radially provided for fixing the positioning block 50 by a knob. The positioning block 50 is fixed to the bracket 1 by a knob (such as a screw or bolt). The specific assembly method is as follows: the knob (taking a screw as an example) passes through the mounting hole on the positioning block 50 and forms a threaded fastening connection with the through hole 60 on the bracket 1. By tightening the screw, the positioning block 50 can be firmly pressed between the bracket 1 and the hanger 20, thereby eliminating assembly gaps and improving the rigidity of the overall structure. The cooperation between the positioning block 50 and the through hole 60 can accurately control the installation position of the hanger 20, ensuring that the workpiece maintains a stable spatial posture during the spraying process, avoiding displacement caused by vibration or rotation, thereby improving the uniformity of spraying.

[0024] For example, one side of the receiving device 21 is provided with a concave / protruding snap-fit ​​portion 211, and the positioning block 50 is connected to the snap-fit ​​portion 211. The snap-fit ​​portion 211 can be a concave groove or two oppositely arranged protrusions, and the gap between the two protrusions is adapted to the positioning block 50, so that the mating structure of the snap-fit ​​portion 211 and the positioning block 50 can effectively suppress the relative displacement caused by rotation or vibration during the spraying process and ensure the positioning accuracy of the workpiece.

[0025] For example, there are at least two rotating components 30 located on the same horizontal plane, and the two rotating components 30 are connected by a rod 32. The two rotating components 30 are linked together by a high-rigidity rod 32 to form a stable frame-type transmission structure, which effectively eliminates the eccentric torque that may be generated by single-point drive, thereby avoiding the cover plate 22 from shaking or jamming during movement. This allows the rod 32 to evenly transmit the driving force to the rotating components 30 on both sides, which reduces the load on a single rotating component and suppresses the risk of mechanism deformation through the action of a couple.

[0026] For example, the rotating assembly 30 includes a support block 33 mounted on the bracket 1, a rotatable rotating rod 34 mounted on the support block 33, a rod body 32 connected to the rotating rod 34, and a connecting part 31 connected to the rod body 32. The rotation of the rotating rod 34 can drive the rod body 32 to rotate, so that the connecting part 31 drives the cover plate 22 to cover or expose the cavity of the accommodating device 21.

[0027] For example, a dust cover 35 is fitted onto the support block 33, and the dust cover 35 has an opening 351 for the rotation trajectory of the rod 32. The dust cover 35 reduces the contact between the rod 32 and dust, and the inside of the dust cover 35 can be pre-coated with grease to reduce the friction at the connection between the rod 32 and the rotating rod 34, further reducing the dryness during rotation.

[0028] The bracket 1 includes a first rod 11, a second rod 12 and a third rod 13. The hangers 20 corresponding to each rod are divided into a first part 23, a second part 24 and a third part 25. The rotating component 30 is located on the first part 23.

[0029] In summary, the key design feature of this utility model is that... The workpiece is loaded into the container 21, and the cover plate 22 is aligned with the positioning block 50 through the snap-fit ​​part 211. The knob is tightened to eliminate the assembly gap. Choose whether to enable the rotating component based on process requirements (e.g., when the finishing surface needs to be shielded). The disc 40 drives the frame 10 to rotate, and all the hangers 20 move synchronously to achieve basic coating coverage; When the rotating component is activated, the rotating rod 34 drives the cover plate 22 to open and close periodically via the rod body 32, exposing / covering specific areas (such as threaded holes), while its rotation improves the uniformity of spraying.

[0030] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
