Description

Technical Field

[0001] The utility model relates to the technical field of workpiece spray painting, in particular to a leveling structure for spraying painting on a lathe base. Background Art

[0002] When processing metal workpieces, in order to ensure dimensional accuracy and shape accuracy, improve processing efficiency, and meet specific functional requirements, lathes are used to process the workpieces, which also improves processing efficiency.

[0003] For the processed workpiece, in order to provide an additional protective layer to prevent corrosion and wear of the workpiece, and also to beautify the appearance and meet specific functional requirements, the workpiece needs to be painted. At the same time, in order to ensure that the paint is evenly adhered to the outer surface of the workpiece, the paint needs to be further smoothed.

[0004] However, when performing smoothing operations, the smoothing roller, whether a single curved roller or a flat roller, is difficult to adapt to different workpiece shapes and difficult to smooth the paint on different workpieces, resulting in poor adaptability of a single smoothing roller. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a leveling structure for painting a lathe base, the purpose of which is to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A leveling structure for painting a lathe base, comprising:

[0008] A first bracket, with second brackets installed on both sides of the first bracket, smoothing rollers installed on the lower sides of the first bracket and the second bracket, the bottom of the second bracket is connected to the second mounting bracket through a connecting bar, the upper end of the second mounting bracket is hinged with an adjustment bracket on the side away from the connecting bar, and sliders are slidably connected inside the two ends of the second mounting bracket.

[0009] Preferably, the first bracket and the second bracket are connected via a first hydraulic rod, the first hydraulic rod is mounted on the outer end of the first bracket, and the output end of the first hydraulic rod is fixed to the inside of the second bracket.

[0010] Preferably, the connecting bar is fixed to a side of the upper end of the second mounting bracket close to the first mounting bracket, and the other end of the connecting bar is hinged to the outer end of the second bracket.

[0011] Preferably, a second hydraulic rod is installed at the lower end of the first bracket, and the output end of the second hydraulic rod is fixed to the first mounting bracket.

[0012] Preferably, the other end of the adjustment frame is hinged with a connecting block, which is slidably connected to the inner side of the lower end of the second bracket. The internal thread of the connecting block is connected to an adjusting rod, which is rotatably connected to the inside of the second bracket.

[0013] Preferably, a support plate is installed above the first hydraulic rod, the support plate is fixed to the outer end of the first bracket, and the second bracket is slidably connected to the support plate.

[0014] Preferably, a cross block is fixed on the side of the slider close to the smoothing roller, and a screw is threadedly connected to the inner side of the end of the slider away from the cross block. The screw is rotatably connected to the inside of the second mounting frame, and a fixing cover is fixed to the end of the screw away from the slider.

[0015] Preferably, the outer sides of both ends of the smoothing roller are rotatably connected to support shafts, and a cross slot is provided on the inner side of the support shaft. When the cross block is docked with the support shaft, the cross block is engaged with the cross slot of the support shaft.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The utility model provides a smoothing structure for painting a lathe base, which rotates an adjusting rod to move a connecting block, and drives the adjusting frame to deflect through the translation of the connecting block, so that the second mounting frame can rotate with the hinge of the connecting bar and the second bracket as the axis, thereby causing the second mounting frame to drive the corresponding smoothing roller to change the angle, so that the smoothing roller corresponding to the second mounting frame can contact the outer surface of the workpiece and perform a smoothing operation on the workpiece. At this time, if the smoothing roller corresponding to the first mounting frame cannot contact the outer surface of the workpiece, the second hydraulic rod is activated to drive the first mounting frame to move, and the position of the smoothing roller corresponding to the first mounting frame is adjusted, thereby improving the adaptability to different workpiece shapes during the smoothing operation;

[0018] During the smoothing operation, the smoothing roller needs to be replaced with a flat or curved smoothing roller according to the shape of the outer surface of the workpiece. At this time, after docking with the slot of the fixed cover through a screwdriver, the screw is rotated first, and then the slider is translated to the side away from the smoothing roller. When the support shafts on both sides of the smoothing roller are not docked with the cross block, the smoothing roller can be removed from the second mounting bracket or the first mounting bracket, and the current smoothing roller can be replaced with a curved or flat smoothing roller.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 and Figure 2 The embodiment proposed in this application is: a smoothing structure for painting a lathe base, comprising a first bracket 1, a handle fixed to the upper end of the first bracket 1, second brackets 2 installed on both sides of the first bracket 1, and smoothing rollers 5 installed on the lower sides of the first bracket 1 and the second bracket 2. After placing the workpiece to be sprayed on the lathe base for painting, the staff holds the handle and smoothes the paint on the outer surface of the workpiece through the smoothing roller 5.

[0027] The first bracket 1 and the second bracket 2 are connected by a first hydraulic rod 11. The first hydraulic rod 11 is installed at the outer end of the first bracket 1, and the output end of the first hydraulic rod 11 is fixed to the inside of the second bracket 2. The extension and contraction of the first hydraulic rod 11 can drive the second bracket 2 on both sides of the first bracket 1 to move, thereby changing the positions of the two second brackets 2 and their corresponding smoothing rollers 5. The second mounting frame 4 is connected to the bottom of the second bracket 2 through a connecting bar 41. One end of the connecting bar is fixed to the second mounting frame 4, and the other end of the connecting bar 41 is hinged to the outer end of the second bracket 2, so that the second mounting frame 4 can rotate through the hinge between the connecting bar 41 and the second bracket 2 as the axis.

[0028] At the same time, a second hydraulic rod 31 is installed at the lower end of the first bracket 1, and the output end of the second hydraulic rod 31 is fixed to the first mounting frame 3. The first mounting frame 3 and the corresponding smoothing roller 5 are moved by the extension and retraction of the second hydraulic rod 31. Hollow telescopic rods can also be installed on both sides of the second hydraulic rod 31 to connect the first mounting frame 3 with the first bracket 1. The hollow telescopic rod is used to keep the first mounting frame 3 stable when moving by the second hydraulic rod 31.

[0029] Specifically, an adjusting frame 23 is hinged on the side of the upper end of the second mounting frame 4 away from the connecting strip 41, and a connecting block 21 is hinged on the other end of the adjusting frame 23. The connecting block 21 is slidably connected to the inner side of the lower end of the second bracket 2, and the internal thread of the connecting block 21 is connected to the adjusting rod 22. The adjusting rod 22 is rotatably connected to the inside of the second bracket 2. The rotation of the adjusting rod 22 can drive the connecting block 21 to translate, and the translation of the connecting block 21 can drive the adjusting frame 23 to deflect, and then push one end of the second mounting frame 4 through the adjusting frame 23. At this time, the second mounting frame 4 rotates around the hinge with the second bracket 2 as the axis, so that the angle of the second bracket 2 and its corresponding smoothing roller 5 changes.

[0030] Furthermore, a support plate 12 is installed above the first hydraulic rod 11, and the support plate 12 is fixed to the outer end of the first bracket 1, and the second bracket 2 is slidably connected to the support plate 12. When the first hydraulic rod 11 drives the second bracket 2 to move by telescoping, the second bracket 2 can slide on the outside of the support plate 12. The support plate 12 reduces the supporting load of the first hydraulic rod 11 on the second bracket 2, thereby extending the service life of the device.

[0031] After the workpiece is placed on the lathe base for spray painting, the paint is smoothed by using the smoothing structure. The worker holds the handle at the upper end of the first bracket 1 to move the smoothing structure, and smoothes the paint on the outer surface of the workpiece by the smoothing roller 5, so that the paint adheres more evenly to the outer surface of the workpiece. When the outer surface of the workpiece is a curved surface, such as the smoothing rollers 5 on the second mounting bracket 4 and the first mounting bracket 3 are at the same level, the smoothing roller 5 corresponding to the second mounting bracket 4 is difficult to contact the paint on the outer surface of the workpiece. At this time, the first hydraulic rod 11 is first started to drive the second bracket 2 to translate to the side away from the first bracket 1, and then the adjusting rod 22 is rotated to move the connecting block 21, and the connecting block 21 is moved. The translation of the connecting block 21 drives the adjustment frame 23 to deflect, so that the second mounting frame 4 can rotate with the hinge of the connecting strip 41 and the second bracket 2 as the axis, thereby causing the second mounting frame 4 to drive the corresponding smoothing roller 5 to change its angle, so that the smoothing roller 5 corresponding to the second mounting frame 4 can contact the outer surface of the workpiece and smooth the workpiece. At this time, if the smoothing roller 5 corresponding to the first mounting frame 3 cannot contact the outer surface of the workpiece, the second hydraulic rod 31 is started to drive the first mounting frame 3 to move, and the position of the smoothing roller 5 corresponding to the first mounting frame 3 is adjusted. By adjusting the angle of the smoothing roller 5, the adaptability to different workpiece shapes during the smoothing operation is improved.

[0032] In another embodiment, see Figure 3 、 Figure 4 and Figure 5 , sliders 6 are respectively slidably connected to the inside of the two ends of the second mounting frame 4, and the positioning of the smoothing roller 5 is adjusted by the slider 6. A cross block 61 is fixed on the side of the slider 6 close to the smoothing roller 5, and a screw 7 is threadedly connected to the inside of the end of the slider 6 away from the cross block 61. The screw 7 is rotatably connected to the inside of the second mounting frame 4, and a fixing cover 71 is fixed to the end of the screw 7 away from the slider 6. The rotation of the screw 7 can drive the slider 6 to translate in the second mounting frame 4, and the support shaft 51 is rotatably connected to the outside of the two ends of the smoothing roller 5, and is docked with the support shaft 51 through the cross block 61 to position the smoothing roller 5.

[0033] A cross slot is provided on the inner side of the support shaft 51 so that after the slider 6 is translated close to the support shaft 51, it can be engaged with the cross slot of the support shaft 51 through the cross block 61 to complete the docking of the cross block 61 and the support shaft 51, so that the slider 6 can position the smoothing roller 5. At the same time, a "cross" or "one" shape should be provided on the outer side of the fixed cover 71 so that the screw 7 can be rotated after docking with the fixed cover 71 through a screwdriver.

[0034] The connection method between the second mounting frame 4 and the smoothing roller 5 is the same as the connection method between the first mounting frame 3 and the smoothing roller 5, and the same operation can be performed.

[0035] During the smoothing operation, the smoothing roller 5 needs to be replaced with a flat or curved smoothing roller 5 according to the shape of the outer surface of the workpiece. At this time, after docking with the slot of the fixed cover 71 through a screwdriver, the screw 7 is first rotated to make the slider 6 translate to the side away from the smoothing roller 5. When the support shafts 51 on both sides of the smoothing roller 5 are not docked with the cross block 61, the smoothing roller 5 can be removed from the second mounting frame 4 or the first mounting frame 3, and the current smoothing roller 5 can be replaced with a curved or flat smoothing roller 5.
