DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0021] In one embodiment, see Figure 1-Figure 3 A paint spraying device for the production of bimetallic cylinder liners includes a central column 2 and a rotatable base 1. The rotatable base 1 is located outside the central column 2 and is rotatably connected to the central column 2. At least one bracket 8 is fixed on the top of the rotatable base 1. The top of the bracket 8 is rotatably connected to a support plate 7. A vertical plate 9 is fixed on the top of the support plate 7. A horizontal plate 10 is fixed on the top of the vertical plate 9. A rotating column 6 runs through the inside of the vertical plate 9. The rotating column 6 is rotatably connected to the vertical plate 9. The rotating column 6 is connected to a top support structure and a rotating mechanism 5. The top support mechanism 4 is used to fix the bimetallic cylinder liner. The rotating mechanism 5 is used to drive the rotating column 6 to rotate. A paint spray head 11 is installed at the bottom of the horizontal plate 10. The support plate 7 is connected to a swinging mechanism 3. The swinging mechanism 3 is used to drive the support plate 7 to swing.

[0022] In this embodiment, when the device is spraying paint on the bimetallic cylinder sleeve, the external rotating device drives the rotatable base 1 to rotate with the central column 2 as the center, and the rotatable base 1 drives the support frame on its top to make a circular motion. In order to improve the painting efficiency of the bimetallic cylinder sleeve, the number of the support frames can be multiple and they are distributed in a circle with the central column 2 as the central axis. While the support frame moves in a circle, it simultaneously drives the vertical plate 9 and the horizontal plate 10 to move in a circle, wherein the vertical plate 9 drives the rotating column 6 to move in a circle, and the horizontal plate 10 drives the paint spray head 11 to move in a circle, and the spray The paint head 11 can be connected to an external paint spraying mechanism. When the rotating column 6 rotates to the working position, the staff quickly puts the bimetallic cylinder sleeve on the outside of the rotating column 6 and makes the end of the bimetallic cylinder sleeve fit with the side wall of the vertical plate 9. As the rotatable base 1 continues to rotate, the supporting mechanism 4 will support the bimetallic cylinder sleeve from the inside, thereby fixing the bimetallic cylinder sleeve and ensuring the stability of the bimetallic cylinder sleeve during the rotation process. After the bimetallic cylinder sleeve is fixed, the paint spraying head 11 at the bottom of the horizontal plate 10 can spray paint on the bimetallic cylinder sleeve. During the painting process, the rotating mechanism 5 drives the bimetallic cylinder liner to rotate through the rotating column 6, so that the paint spraying head 11 can fully spray the bimetallic cylinder liner, effectively improving the painting efficiency of the bimetallic cylinder liner. When the bimetallic cylinder liner is painted, as the rotatable base 1 continues to rotate, the supporting mechanism 4 automatically releases the supporting mechanism for the bimetallic cylinder liner, and the swing mechanism 3 drives the supporting plate 7 to swing, so that the supporting plate 7 drives the rotating column 6 to tilt downward through the vertical plate 9. At this time, the painted bimetallic cylinder liner automatically falls off from the rotating column 6. Then the purpose of automatic unloading is achieved, that is, the paint spraying device drives multiple workstations to move synchronously in a circular motion through the rotatable base 1, thereby realizing continuous loading, automatic fixation and spraying operations of the bimetallic cylinder liner. During the rotation process, the supporting mechanism 4 firmly fixes the workpiece from the inside, and the rotating mechanism 5 drives the cylinder liner to rotate, ensuring that the paint spray head 11 can achieve uniform spraying without dead angles. After the spraying is completed, the supporting mechanism 4 is automatically released and driven by the swing mechanism 3 to tilt and unload, which greatly improves the spraying efficiency, coating quality and degree of automation, while reducing the intensity of manual operation.

[0023] See also Figure 1 and Figure 4 The swing mechanism 3 includes a guide block 31 fixedly connected to the rotatable base 1, a slide 32 is passed through the guide block 31, and the slide 32 is slidably connected to the guide block 31. The end of the slide 32 away from the center column 2 is rotatably connected to the connecting rod 33, and the other end of the connecting rod 33 is rotatably connected to the bottom of the support plate 7. A connecting block 34 is installed at the bottom of the support plate 7, and the connecting block 34 is rotatably connected to the top of the bracket 8 through a torsion spring 35. An extrusion block 311 capable of extruding the slide 32 is fixed on the side wall of the center column 2, and a fixing component capable of fixing the slide 32 is provided inside the guide block 31; After the bimetallic cylinder sleeve is painted, as the rotatable base 1 rotates, the supporting mechanism 4 first releases the fixation of the bimetallic cylinder sleeve, and then the fixing assembly releases the fixation of the push rod 42. At this time, the support plate 7 drives the rotating column 6 to tilt downward through the vertical plate 9 under the action of the torsion spring 35, and the painted bimetallic cylinder sleeve automatically falls off from the rotating column 6, thereby achieving the purpose of automatic unloading. After the bimetallic cylinder sleeve falls off from the rotating column 6, as the rotatable base 1 continues to rotate, the extrusion block 311 squeezes the slide plate 32, and the slide plate 32 drives the support plate 7 to rotate through the connecting rod 33, so that the support plate 7 becomes horizontal again, and when the support plate 7 becomes horizontal again, the fixing assembly inside the guide block 31 will automatically fix the support plate 7, thereby ensuring the stability of the support plate 7.

[0024] See also Figure 1 and Figure 4 The fixing assembly includes a pin rod 36 that passes through the top of the guide block 31. The pin rod 36 is connected to the top of the guide block 31 through a first elastic member 37. A first magnet 38 is fixed to the top of the pin rod 36. A fixing block 39 is fixed to the side wall of the center column 2. A second magnet 310 is fixed to the bottom of the fixing block 39. The first magnet 38 and the second magnet 310 have the same magnetic properties. When the bimetallic cylinder sleeve falls off the rotating column 6, as the rotatable base 1 continues to rotate, the extrusion block 311 squeezes the slide plate 32, and the slide plate 32 drives the support plate 7 to rotate through the connecting rod 33. When the support plate 7 becomes horizontal again, the end of the pin rod 36 automatically enters the pin groove under the action of the first elastic member 37. At this time, the pin rod 36 fixes the slide plate 32 through the pin groove, effectively ensuring the stability of the support plate 7. The first elastic member 37 can be a spring, and when the bimetallic cylinder sleeve is painted, as the rotatable base 1 rotates, when the first magnet 38 rotates to below the second magnet 310, the second magnet 310 and the first magnet 38 attract each other and drive the pin rod 36 to move upward, thereby releasing the fixed state of the pin rod 36 on the slide plate 32, so that the support plate 7 can swing automatically under the action of the torsion spring 35.

[0025] See also Figure 2 and Figure 5 The supporting mechanism 4 includes a push rod 42 that passes through the end of the rotating column 6. The push rod 42 is slidably connected to the end of the rotating column 6. One end of the push rod 42 located inside the rotating column 6 is rotatably connected to a symmetrically distributed movable rod 43. The other end of the movable rod 43 is rotatably connected to a support rod 44. The support rod 44 passes through the side wall of the rotating column 6 and is slidably connected to the side wall of the rotating column 6. An arc block 41 that can squeeze the push rod 42 is fixed on the side wall of the central column 2; When spraying paint on the bimetallic cylinder sleeve, the rotatable base 1 is driven to rotate with the central column 2 as the center by an external rotating device, and the rotatable base 1 drives the support frame on its top to make a circular motion. When the rotating column 6 rotates to the working position, the staff quickly puts the bimetallic cylinder sleeve on the outside of the rotating column 6, and makes the end of the bimetallic cylinder sleeve fit with the side wall of the vertical plate 9. As the rotatable base 1 continues to rotate, the arc block 41 applies pressure to the push rod 42, and the push rod 42 drives the support rod 44 to move outward through the movable rod 43. When the pressure applied by the arc block 41 to the push rod 42 no longer changes, the end of the support rod 44 fits tightly with the inner wall of the bimetallic cylinder sleeve. At this time, the support rod 44 fixes the bimetallic cylinder sleeve, thereby effectively improving the stability of the bimetallic cylinder sleeve during the painting process.

[0026] See also Figure 5 A limiting rod 45 is fixed on the inner wall of the rotating column 6, and the limiting rod 45 extends into the interior of the push rod 42 and is slidably connected to the push rod 42. A second elastic member 46 is provided on the outside of the limiting rod 45, and both ends of the second elastic member 46 are fixedly connected to the end of the push rod 42 and the inner wall of the rotating column 6 respectively; After the bimetallic cylinder liner is painted, as the rotatable base 1 continues to rotate, the pressure exerted by the arc block 41 on the push rod 42 causes the push rod 42 to automatically reset under the action of the second elastic member 46, so that the support rod 44 no longer supports the bimetallic cylinder liner. The second elastic member 46 can be a spring, and the limit rod 45 can limit the push rod 42, thereby effectively improving the stability of the push rod 42 when moving.

[0027] See also Figure 3 The rotating mechanism 5 includes a first bevel gear 51 fixed to the outside of the rotating column 6, the first bevel gear 51 is meshed with a second bevel gear 52, a rotating rod 53 is fixed to the top of the second bevel gear 52, the rotating rod 53 passes through the horizontal plate 10 and is rotatably connected to the horizontal plate 10, and the upper end of the rotating rod 53 is connected to a rotating assembly, which is used to drive the rotating rod 53 to rotate; When spraying paint on the bimetallic cylinder liner, as the rotatable base 1 continues to rotate, the rotating assembly drives the rotating rod 53 to rotate, and the rotating rod 53 drives the second bevel gear 52 to rotate. The engagement of the first bevel gear 51 and the second bevel gear 52 drives the rotating column 6 to rotate, so that the paint spraying head 11 can comprehensively spray paint on the bimetallic cylinder liner, ensuring the uniformity of the paint spraying.

[0028] See also Figure 2 and Figure 3 The rotating assembly includes a circular gear 54 fixed to the top of the rotating rod 53, and an arc-shaped toothed plate 55 capable of meshing with the circular gear 54 is fixed to the side wall of the central column 2; When the bimetallic cylinder liner is being sprayed with paint, as the rotatable base 1 continues to rotate, the circular gear 54 at the end of the rotating rod 53 will engage with the arc-shaped tooth plate 55 on the side wall of the center column 2. The engagement between the arc-shaped tooth plate 55 and the circular gear 54 drives the rotating rod 53 to rotate, thereby enabling the rotating column 6 to drive the bimetallic cylinder liner to rotate.

[0029] Working principle: When the device is spraying paint on the bimetallic cylinder sleeve, the external rotating device drives the rotatable base 1 to rotate with the central column 2 as the center, and the rotatable base 1 drives the support frame on its top to make a circular motion, and the support frame drives the vertical plate 9 and the horizontal plate 10 to make a circular motion, wherein the vertical plate 9 drives the rotating column 6 to make a circular motion, and the horizontal plate 10 drives the spray head 11 to make a circular motion. When the rotating column 6 rotates to the working position, the staff quickly puts the bimetallic cylinder sleeve on the outside of the rotating column 6, and makes the end of the bimetallic cylinder sleeve fit with the side wall of the vertical plate 9. As the rotatable base 1 continues to rotate, the arc block 41 applies pressure to the push rod 42, and the push rod 42 drives the support rod 44 to move outward through the movable rod 43. When the pressure exerted by the arc block 41 on the push rod 42 no longer changes, the end of the support rod 44 is tightly fitted with the inner wall of the bimetallic cylinder sleeve. At this time, the support rod 44 has a fixing effect on the bimetallic cylinder sleeve. After the bimetallic cylinder sleeve is fixed, the paint spraying head 11 at the bottom of the cross plate 10 can spray paint on the bimetallic cylinder sleeve. During the painting process, the circular gear 54 at the end of the rotating rod 53 will mesh with the arc-shaped tooth plate 55 on the side wall of the center column 2. The meshing of the arc-shaped tooth plate 55 and the circular gear 54 drives the rotating rod 53 to rotate, and the rotating rod 53 drives the second bevel gear 52 The engagement of the first bevel gear 51 and the second bevel gear 52 drives the rotating column 6 to rotate, so that the paint spraying head 11 can fully spray the bimetallic cylinder sleeve, ensuring the uniformity of the paint spraying. When the bimetallic cylinder sleeve is painted, the pressure exerted by the arc block 41 on the push rod 42 automatically resets the push rod 42, and the support rod 44 no longer supports the bimetallic cylinder sleeve. As the rotatable base 1 rotates, when the first magnet 38 rotates to below the second magnet 310, the second magnet 310 and the first magnet 38 attract each other and drive the pin rod 36 to move upward, thereby releasing the fixing state of the pin rod 36 on the slide plate 32. At this time, the support plate 7 drives the rotating column 6 to tilt downward through the vertical plate 9 under the action of the torsion spring 35, and the painted bimetallic cylinder sleeve automatically falls off from the rotating column 6, thereby achieving the purpose of automatic unloading. After the bimetallic cylinder sleeve falls off from the rotating column 6, as the rotatable base 1 continues to rotate, the extrusion block 311 squeezes the slide plate 32, and the slide plate 32 drives the support plate 7 to rotate through the connecting rod 33. When the support plate 7 becomes horizontal again, the end of the pin rod 36 automatically enters the pin groove. At this time, the pin rod 36 fixes the slide plate 32 through the pin groove, effectively ensuring the stability of the support plate 7.
