Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0015] like Figs. 1-2As shown, the engine casing spraying equipment includes a workbench 1, a cantilever 2, a lead screw assembly 3, and a nozzle assembly 4. The cantilever 2 includes a first cylinder 21, a second cylinder 22, a third cylinder 23, an upper cantilever 24, a lower cantilever 25, a base 26, and a guide rail seat 27. The guide rail seat 27 is vertically mounted on the side wall of the workbench 1. The base 26 is movably engaged with the guide rail seat 27. The output end of the first cylinder 21 is movably connected to the base 26, and the fixed end of the first cylinder 21 is hinged to the guide rail seat 27. The lower cantilever 25 is movably mounted between the upper cantilever 24 and the base 26. The fixed end of the second cylinder 22 is hinged to the upper surface of the base 26, and its output end is movably connected to the middle of the lower cantilever 25. The fixed end of the third cylinder 23 is hinged to the lower cantilever 25, and its output end is movably connected to the rear end of the upper cantilever 24. The front end of the upper cantilever 24 is connected to the lead screw assembly 3, and the nozzle assembly 4 is mounted on the lead screw assembly 3. Specifically, in this embodiment, the workbench 1 is used to load and clamp the workpiece (not shown in the figure) to prevent workpiece displacement during the spraying process. Meanwhile, since the workpieces are mostly irregularly shaped, to achieve large-area, multi-angle spraying operations, we use a cantilever 2 in conjunction with a lead screw assembly 3 to install the nozzle assembly 4. This allows the nozzle assembly 4 to move over a large range during spraying, achieving spraying of the workpiece at a fixed angle and position, avoiding missed areas. The cantilever 2 includes a first cylinder 21, a second cylinder 22, a third cylinder 23, an upper cantilever 24, a lower cantilever 25, a base 26, and a guide rail 27. The first cylinder 21 can drive the base 26 to move vertically along the guide rail 27, while the second cylinder 22 and the third cylinder 23 work together to drive the lower cantilever 25 and the upper cantilever 24 to rotate, thereby adjusting the angle and height of the nozzle assembly 4, enabling multi-angle spraying operations on workpieces of different sizes and shapes. The lead screw assembly 3 can drive the nozzle assembly 4 to move laterally, completing large-area operations and preventing missed areas on the edges of the workpiece.

[0016] like Figs. 1-2As shown, the lead screw assembly 3 includes a base plate 31, a drive motor 32, a housing 33, a lead screw 34, and a sliding sleeve 35. The base plate 31 is mounted on the upper cantilever 24. The drive motor 32 and the housing 33 are mounted side-by-side on the base plate 31, and the output end of the drive motor 32 is movably connected to a pulley at the end of the lead screw 34 via a belt. The lead screw 34 is movably mounted inside the housing 33 via a bearing. The sliding sleeve 35 is movably fitted onto the lead screw 34. The nozzle assembly 4 is connected to the sliding sleeve 35. Specifically, we arrange the drive motor 32 and the housing 33 side-by-side to avoid directly connecting the drive motor 32 to the lead screw 34, thereby reducing the overall length of the lead screw assembly 3 and preventing the drive motor 32 from colliding with other equipment and being damaged during spraying operations in confined spaces. The drive motor 32 drives the lead screw 34 to rotate inside the housing 33 via a belt, which in turn causes the sliding sleeve 35 to reciprocate linearly along the axial direction of the lead screw 34. Understandably, the opening on one side of the housing 33 allows the end of the sliding sleeve 35 to protrude, facilitating connection with the nozzle assembly 4. At the same time, the housing 33 also serves as a limit to prevent the sliding sleeve 35 from deviating during reciprocating motion.

[0017] like Figs. 1-2 As shown, the nozzle assembly 4 includes a nozzle body 41 and a bracket 42. One end of the bracket 42 is connected to the sliding sleeve 35, and the other end of the bracket 42 is connected to the nozzle body 41. Specifically, the bracket 42 is used to mount the nozzle body 41, which can be connected to the paint tank (not shown in the figure) via a corrugated hose.

[0018] like Figs. 1-2 As shown, a rotary table 11 is provided at the center of the upper end of the worktable 1. The output end of the rotary table 11 is connected to the glass plate 12, driving the glass plate 12 to rotate. A magnetic block for magnetically attracting the workpiece is provided on the lower end surface of the glass plate 12. Specifically, in this embodiment, the rotary table 11 can drive the glass plate 12 for placing the workpiece to rotate, thereby actively adjusting the orientation of the workpiece. The surface of the glass plate 12 is extremely smooth. To prevent the workpiece from slipping during rotation, we use magnetic attraction to fix the workpiece. That is, a magnetic block is provided on the lower end surface of the glass plate 12. The magnetic block is magnetically connected to the iron positioning pin on the workpiece, thereby magnetically positioning the workpiece and preventing it from slipping during rotation. Moreover, no other clamping fixtures are required, greatly reducing the tooling cost.

[0019] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
