However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0012] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0013] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0014] To solve the above technical problems, such as Figure 1-3 As shown, this utility model designs a metal part spraying device, including a workpiece support mechanism. The workpiece support mechanism is used to send the workpiece to the spraying station for spraying by a spray gun (not shown in the figure). The workpiece support mechanism includes a lifting cylinder 1, a lifting plate 2, a fixed plate 3, a support plate 4, and a synchronous rotation drive assembly. The piston rod of the lifting cylinder 1 faces upward and is fixedly connected to the lifting plate 2. A support rod 5 is provided at each of the four corners of the lifting plate 2. The support rod 5 passes through the through hole of the fixed plate 3 and its top is connected to the support plate 4. The lifting cylinder 1 is used to drive the lifting plate 2 to move up and down. The cooperation between the lifting cylinder 1 and the lifting plate 2 can accurately send the workpiece to the spraying station, and the structure of the support rod 5 and the fixed plate 3 can achieve stable up and down driving of the support plate.

[0015] The synchronous rotation drive assembly is mounted on the fixed plate 3. The synchronous rotation drive assembly includes four symmetrically arranged support shafts 6 that can rotate synchronously. Each support shaft 6 has a support plate 7 on its top. The support plate 7 is used to support the workpiece. By setting four symmetrically arranged support shafts 6 and support plates 7, multiple workpieces can be supported at the same time and rotated synchronously. This design breaks through the limitations of traditional single workpiece spraying and greatly improves spraying efficiency. It is especially suitable for mass production scenarios. The synchronous rotation drive assembly ensures that the workpiece can rotate evenly during the spraying process, so that the spray gun can spray the workpiece surface in all directions and evenly, effectively avoiding the problems of spraying dead corners and inconsistent coating thickness, and significantly improving the spraying quality.

[0016] It is worth mentioning that the corresponding spray guns are preferably set to four, which are set on the four sides facing the corresponding positions of their respective workpieces, so as to achieve all-round, no dead angle spraying coverage and significantly improve spraying efficiency and quality.

[0017] In this embodiment, it is further preferred that the synchronous rotation drive assembly includes a driven gear 8, a driving gear 9, and a drive motor 10. Each support shaft 6 is fixedly engaged with a driven gear 8 and coaxially arranged. The drive motor 10 is located at the bottom of the support plate 4, and the output shaft of the drive motor 10 is fixedly engaged with the driving gear 9 and coaxially arranged. The four driven gears 8 are symmetrically arranged in pairs around the center of the driving gear 9. The driven gears 8 and the driving gear 9 mesh to achieve transmission, realizing efficient power transmission from the drive motor 10 to each support shaft 6. The meshing transmission between the driving gear 9 and the driven gear 8 ensures that the four support shafts 6 can rotate precisely and synchronously, thereby ensuring that multiple workpieces maintain a consistent rotation speed and angle during the spraying process, further improving the uniformity and consistency of the spraying. In addition, the gear transmission system has high torque transmission capability and stable mechanical performance, and can withstand large loads, ensuring the stability and reliability of the equipment during long-term operation. At the same time, the compact structural design of the gear transmission further optimizes the overall layout of the equipment and reduces space occupation.

[0018] By using a single drive motor 10 to simultaneously drive the rotation of multiple workpieces, energy consumption and equipment costs are significantly reduced compared to configuring a separate drive device for each workpiece. This design not only improves the economic efficiency of the equipment but also aligns with the industrial development trend of energy conservation and emission reduction.

[0019] In this embodiment, it is further preferred that the bottom of the support plate 4 is provided with a bearing seat 11, and a bearing is installed in the bearing seat 11. The bottom end of the support shaft 6 cooperates with the bearing in the bearing seat 11. The use of the bearing can significantly reduce the friction between the support shaft 6 and the support plate 4, reduce the loss of mechanical energy, and effectively reduce the wear of the support shaft 6 and the support plate 4, extend the service life of the equipment, and reduce the maintenance cost of the equipment.

[0020] In this embodiment, it is further preferred to include guide sleeves 12. The fixing plate 3 is used to fix and cooperate with the equipment frame. A guide sleeve 12 is provided at each of the four corner through holes of the fixing plate 3. The inner hole of the guide sleeve 12 coincides with the axis of the through hole. The bottom of the guide sleeve 12 is provided with a convex plate portion. The convex plate portion is provided with several bolt holes. The guide sleeve 12 is connected to the fixing plate 3 by bolt connection. This detachable connection method makes the installation and replacement of the guide sleeve 12 more convenient and quick. The support rod 5 passes through the inner hole of the guide sleeve 12 and slides with it. The inner hole of the guide sleeve 12 coincides with the axis of the through hole, which can accurately guide the lifting and lowering movement of the support rod 5, ensuring that the support rod 5 always maintains linear movement during the lifting and lowering process, and avoiding swaying or deflection.

[0021] In this embodiment, it is further preferred that the pallet 7 is frustum-shaped, and two arc-shaped limiting blocks 13 are symmetrically arranged around the center of the pallet 7. The arc-shaped limiting blocks 13 protrude from the upper surface of the pallet 7, which can effectively limit the radial movement of the workpiece, ensure that the workpiece remains in a fixed position during the spraying process, and avoid the workpiece from shifting due to rotation or external force during the spraying process. The arc-shaped limiting blocks 13 are preferably installed by bolts, so they can be selectively disassembled and assembled according to actual needs.

[0022] In this embodiment, it is further preferred that a protective cover 14 is provided above the support plate 4. The protective cover 14 is used to cover the synchronous rotation drive component inside. The protective cover 14 is provided with a clearance hole for the support shaft 6 to pass through. The protective cover 14 can effectively prevent the operator from accidentally contacting the rotating drive component, avoid personnel injury caused by misoperation or accidental contact, and improve the safety of the equipment. At the same time, the protective cover 14 can prevent dust, debris and other objects from entering the drive component, reduce equipment failure caused by foreign object interference, and improve the operational stability of the equipment.

[0023] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
