Description

Technical Field

[0001] This utility model relates to the technical field of surface processing, and in particular to a flow coating device for an outer mold surface. Background Technology

[0002] In industrial production, flow coating on the outer surface of molds is a crucial process that directly affects product quality and appearance. Traditional flow coating methods often rely on manual operation, which is not only inefficient but also makes it difficult to achieve uniform coating on the workpiece surface, thus impacting the overall product quality. Furthermore, due to the varying shapes and positions of workpieces, traditional methods often require individual adjustments for each workpiece, significantly increasing operational complexity and time costs.

[0003] With the continuous development of industrial automation, some highly automated flow coating equipment has emerged in the market. However, these equipment are often complex in structure, expensive, and poorly adaptable to workpieces of different shapes and positions. In particular, when processing workpieces with complex shapes, traditional equipment often struggles to ensure uniform flow coating on the workpiece surface. At the same time, the cumbersome adjustment process also greatly limits the improvement of production efficiency. Utility Model Content

[0040] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0041] This utility model relates to a coating device for the surface of an outer mold, such as... Figures 1 to 7 As shown, it includes:

[0042] The support mechanism 1 is independently fixed and serves as the basic structure of the entire device, providing necessary mechanical support and stability. Multiple mounting brackets 2 are equidistantly arranged on the support mechanism 1. A connecting shaft 3 is rotatably installed in the inner hole of the mounting bracket 2, and a connecting bracket 4 is fixedly installed on the connecting shaft 3. A support shaft 5 is rotatably installed on the connecting bracket 4, and a chuck 6 is coaxially installed on the support shaft 5. The chuck 6 is used to clamp the workpiece.

[0043] The adjustment mechanism 7 is mounted on the support mechanism 1 and is connected to multiple connecting shafts 3. The adjustment mechanism 7 is used to adjust the installation angle between the connecting frame 4 and the mounting frame 2 to meet the requirements of different workpiece positions and angles.

[0044] Multiple drive mechanisms 8 are respectively mounted on multiple mounting brackets 2. The drive mechanisms 8 are used to support the shaft 5 to drive the chuck 6 to rotate.

[0045] The power mechanism 9 is mounted on the support mechanism 1 and is used to adjust the work positions of multiple chucks 6. The power mechanism 9 can automatically switch between work positions according to a preset program.

[0046] The working principle of this device is as follows:

[0047] First, the support angle of the workpiece is adjusted by the adjustment mechanism. Then, the workpiece to be processed is clamped in the chuck 6. Then, the power mechanism 9 adjusts the positions of multiple chucks 6 according to the preset program to ensure smooth switching between the positions. When the workpiece rotates to the flow coating area, the drive mechanism 8 in the flow coating area is started. The support shaft 5 drives the chuck 6 and the workpiece to rotate, providing the necessary motion conditions for surface flow coating. After the workpiece flow coating is completed, the power mechanism 9 drives the workpiece to rotate at the position again.

[0048] The designed support mechanism 1 provides a stable foundation, ensuring the stability and reliability of the entire flow coating device during operation. The combined design of the mounting frame 2, connecting shaft 3, support shaft 5, and chuck 6 enables flexible clamping of workpieces at multiple angles, greatly improving the applicability and flexibility of the device. The adjustment mechanism 7 allows the installation angle between the connecting frame 4 and the mounting frame 2 to be adjusted as needed, meeting the flow coating needs of workpieces with different shapes and positions, and enhancing the versatility and efficiency of the device. The configuration of multiple drive mechanisms 8 can independently drive the rotation of each chuck 6, ensuring uniform flow coating on the workpiece surface and improving processing quality and efficiency. The introduction of the power mechanism 9 enables automatic switching between workstations, which not only simplifies the operation process but also significantly improves the degree of automation and reduces labor costs. At the same time, it executes according to the preset program, ensuring the consistency and accuracy of the flow coating operation. Overall, the external mold surface flow coating device of this utility model has a compact structure and comprehensive functions, greatly improving the flexibility and automation level of workpiece flow coating operations.

[0049] As a preferred option, such as Figure 1 and Figure 2 As shown, the support mechanism 1 includes:

[0050] The base 11, as the basic part of the entire support mechanism 1, has multiple adjustable feet 12 at its bottom end for adjusting the levelness of the base 11.

[0051] Mounting post 13 is set in the inner hole of base 11, and mounting post 13 can rotate freely around the inner hole of base 11. Multiple mounting brackets 2 are equidistantly arranged at the top of mounting post 13.

[0052] The base 11, as the foundation of the entire support mechanism, provides a stable support surface, ensuring the stability of the flow coating device during operation. The multiple adjustable feet 12 at the bottom of the base 11 can flexibly adjust the level of the base, effectively dealing with uneven working surfaces, further enhancing the stability and adaptability of the device. The setting of the mounting column 13 not only realizes the equidistant distribution of the mounting frame 2, but also its characteristic of freely rotating around the inner hole of the base gives the entire support mechanism greater flexibility, making it easy to adjust the position of the chuck 6, laying a solid foundation for efficient and high-quality flow coating of the workpiece.

[0053] As a preferred option, such as Figures 1 to 6 As shown, the adjustment mechanism 7 includes:

[0054] The drive shaft 71 is disposed in the shaft cavity of the mounting column 13, and the drive shaft 71 is coaxially mounted with the mounting column 13;

[0055] The transmission gear 72 is coaxially mounted on the transmission shaft 71;

[0056] Multiple transmission shafts 73 are rotatably mounted on the mounting column 13, and each transmission shaft 73 corresponds to a mounting bracket 2. A connecting gear 74 is coaxially mounted on the transmission shaft 71, and multiple connecting gears 74 are meshed with the transmission gear 72. A worm gear 75 is coaxially mounted on the transmission shaft 73.

[0057] Multiple worm gears 76 are coaxially mounted on multiple connecting shafts 3, and the worm 75 is meshed with the worm gears 76.

[0058] An adjusting wheel 77 is coaxially mounted on the drive shaft 71;

[0059] The working principle of the adjusting mechanism 7 of this device is as follows:

[0060] First, the drive shaft 71 is started to rotate by adjusting wheel 77. The drive gear 72 on the drive shaft 71 drives multiple connecting gears 74 to rotate synchronously through meshing. The connecting gears 74 then transmit the rotational power to the worm 75 through the transmission shaft 73. Due to the cooperation between the worm 75 and the worm wheel 76, each connecting shaft 3 can be precisely adjusted according to the preset program. When it is necessary to adjust the angle of the workpiece, the user can rotate the adjusting wheel 77 to change the installation angle of the connecting frame 4 relative to the mounting frame 2. This design not only improves the flexibility of workpiece processing, but also enhances the consistency and quality of the processing effect.

[0061] As a preferred option, such as Figures 1 to 6 As shown, the drive mechanism 8 includes:

[0062] The drive motor 81, as the power source of the entire drive system, is mounted on the connecting frame 4, and the output end of the drive motor 81 is equipped with a drive gear 82.

[0063] Driven gears 83 are coaxially mounted on support shaft 5, and driving gear 82 is meshed with driven gear 83;

[0064] A connecting mechanism 84 is mounted on the mounting post 13. The connecting mechanism 84 is used to supply power to the drive motor 81 of the flow coating area.

[0065] The working principle of the drive mechanism 8 of this device is as follows:

[0066] When the workpiece rotates to the flow coating zone, the drive motor 81 in the flow coating zone starts. The drive motor 81, through the drive gear 82 at its output end, meshes with the driven gear 83 on the support shaft 5, transmitting rotational power to the support shaft 5. At this time, the support shaft 5 drives the chuck 6 and the workpiece clamped on it to rotate, providing the necessary motion conditions for surface flow coating. Since each drive motor 81 can be controlled independently, the rotational speed and direction of each chuck 6 can be adjusted according to the preset program to ensure the uniformity and consistency of the flow coating on the workpiece surface. At the same time, the connecting mechanism 84 is responsible for supplying power to the drive motor 81 in the flow coating zone to ensure its normal operation. Since power is only supplied to the drive motor 81 in the flow coating zone, not only is energy saving achieved for the device, but workpieces in non-flow coating zones can also be disassembled and replaced.

[0067] As a preferred option, such as Figure 3 As shown, the connecting mechanism 84 includes:

[0068] A conductive post 84a is disposed on the base 11 and passes through the inner cavity of the transmission shaft 71. A connecting rod 84b is disposed on the conductive post 84a.

[0069] Multiple connecting posts 84c are respectively disposed on the mounting post 13, and the multiple connecting posts 84c pass through the through cavity of the transmission shaft 73. The connecting posts 84c are electrically connected to the adjacent drive motor 81, and the connecting rod 84b contacts the connecting posts 84c in the flow coating area.

[0070] The working principle of the connecting mechanism 84 of this device is as follows:

[0071] When the mounting column 13 rotates to bring a certain station into the flow coating zone, the connecting rod 84b will automatically contact the corresponding connecting column 84c. At this time, the conductive column 84a transmits power to the drive motor 81 located in the flow coating zone through the connecting rod 84b and the connecting column 84c, causing it to start and drive the chuck 6 and the workpiece to rotate, providing the necessary motion conditions for surface flow coating. Meanwhile, since the connecting rod 84b only contacts the connecting column 84c in the flow coating zone, the other drive motors 81 not in the flow coating zone remain de-energized. This design not only achieves precise power supply to the drive motors 81 in the flow coating zone, but also avoids unnecessary power waste, achieving energy saving. In addition, for workpieces outside the flow coating zone, they can be safely disassembled and replaced in the power-off state, further improving the safety and convenience of operation.

[0072] As a preferred option, such as Figures 3 to 7 As shown, the power mechanism 9 includes:

[0073] The power motor 91 is located inside the base 11. The power motor 91 serves as the core power source of the entire power mechanism, and a sector gear 92 is provided at the output end of the power motor 91.

[0074] The auxiliary gear 93 is coaxially mounted on the mounting column 13, and the sector gear 92 meshes with the auxiliary gear 93. A single meshing of the sector gear 92 and the auxiliary gear 93 drives multiple chucks 6 to rotate one station.

[0075] Multiple arc grooves are equidistantly arranged on the auxiliary gear 93, and the arc grooves correspond one-to-one with the mounting bracket 2;

[0076] A limiting component 94 is coaxially mounted on the output end of the power motor 91, and the limiting component 94 is slidably connected to the arc groove. When the sector gear 92 meshes with the auxiliary gear 93, the limiting component 94 is disengaged from the arc groove.

[0077] The working principle of the power mechanism 9 in this device is as follows:

[0078] When a workstation needs to be switched, the power motor 91 starts and engages with the auxiliary gear 93 through the sector gear 92 at its output end, driving the mounting column 13 to rotate. Since the auxiliary gear 93 is coaxially mounted with the mounting column 13, the rotation of the mounting column 13 will drive multiple chucks 6 to rotate synchronously at one workstation. Each time the sector gear 92 and the auxiliary gear 93 engage once, the limiting piece 94 will disengage from the current arc groove and reposition itself in the arc groove of the next workstation. This design not only achieves precise workstation switching but also avoids error accumulation caused by excessive rotation, ensuring the accuracy and consistency of each workstation switch. After the workpiece has completed the flow coating process, the sector gear 92 and the auxiliary gear 93 engage again to prepare for the next round of flow coating or workpiece replacement.

[0079] The surface coating device for an outer mold of this utility model can be installed, connected or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effect.

[0080] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
