Description

Technical Field

[0001] The invention relates to the technical field of electrophoretic coating equipment, and in particular to an electrophoretic coating hanger which is convenient for height adjustment. Background Art

[0002] Electrophoretic coating is a coating method that uses an external electric field to direct the migration of pigments, resins and other particles suspended in the electrophoretic liquid and deposit them on the surface of a substrate at one of the electrodes. The resin contained in the cathode electrophoretic coating has alkaline groups, which are soluble in water after being neutralized with acid to form salts. After direct current is passed, the acid radical negative ions move toward the anode, and the resin ions and the pigment particles wrapped in them move toward the cathode with positive charge and are deposited on the cathode. This is the basic principle of electrophoretic coating. During the coating process, the components need to be hung with hangers and placed in the electrophoretic tank for coating.

[0003] However, the electrophoretic coating hanger in the prior art generally adopts a fixed structure, and its height cannot be adjusted, and it cannot adapt to workpieces of different sizes, which affects the application scope of the hanger and needs to be improved urgently.

When it is adjusted to an appropriate position, due to the weight of the adjusting plate itself, the sleeve has a tendency to move downward on the limit rod. At this time, the buckle is clamped on the limit rod and the sleeve cannot move downward; when the adjusting plate needs to be moved downward, the buckle is rotated so that the buckle is disengaged from the through hole on the sleeve, and the sleeve drives the adjusting plate to move downward on the limit rod. When the section is completed, release the buckle, and the torsion of the No. 1 torsion spring will press the buckle against the outer wall of the limit rod; when it is necessary to adjust the left and right spacing of the boom on the front side wall of the adjustment plate, rotate the elastic steel sheet on the adjustment seat that needs to be adjusted around the No. 2 rotating shaft, and insert the positioning rod into the inside of the limit hole. At this time, rotate the screw rod, and the nut block drives the adjustment seat to adjust the left and right position on the No. 2 guide rod, and the other unfixed nut blocks rotate with the screw rod and remain in position; after the adjustment is completed, hang the workpiece on the boom, and hang the entire device in the electric swimming pool through the hanging ring for painting.

[0013] After adopting the above structure, the beneficial effects of the present invention are:

[0014] 1. The height between the upper and lower adjustment plates is adjusted by the height adjustment mechanism, so as to adjust the distance between the upper and lower booms. The adjustment method is relatively simple and easy to operate.

[0015] 2. Turn the screw rod, fix the nut block and the adjustment seat through the positioning rod, adjust the distance between adjacent boom brackets, and thus adjust the distance between the workpieces on the left and right sides, which is easy to operate; at the same time, multiple or single adjustment seats can be selectively adjusted, which increases the flexibility of the device.

The rear end of the suspension arm 8-10 is rotatably sleeved on the middle part of the third rotating shaft 17 through a bearing, and a second torsion spring 18 is sleeved on the third rotating shaft 17 on the left and right sides of the suspension arm 8-10. One side arm of the second torsion spring 18 is fixedly connected to the side wall of the suspension arm 8-10, and the other side arm of the second torsion spring 18 is fixedly connected to the side wall of the suspension arm 8-10. It is fixedly connected to the inner wall of the groove 16; a limit plate 19 is fixedly welded on the lower side of the groove 16, and the limit plate 19 is set to limit the bottom surface of the boom 8-10; when the boom 8-10 is not in use, the boom 8-10 rotates around the third rotating shaft 17 under the torsion of the second torsion spring 18, so that the boom 8-10 is close to the connecting rod 15, reducing the space occupied by the boom 8-10; when the boom 8-10 is in use, the workpiece is hung at the end of the boom 8-10, and the boom 8-10 is placed on the limit plate 19; slots 20 are opened at equal intervals on the upper side of the boom 8-10; when the workpiece is hung on the boom 8-10, the slots 20 effectively prevent the workpiece from sliding on the boom 8-10;

[0030] A scale layer 10 is fixedly engraved on one side of the rear side wall of the fixing frame 1, and a slide rail 11 is fixedly provided on the right side wall of the fixing frame 1 by bolts, and several sliders 12 are slidably provided on the slide rail 11, and the number of sliders 12 is set corresponding to the number of adjustment plates 5, and positioning plates 13 are fixedly welded on the front side walls of the several sliders 12, and the upper side surface of the positioning plate 13 is flush with the top surface of the slider 12, and the positioning plate 13 is limited by the linear bearing 6 located on the right side; a locking bolt 14 is inserted on the right side wall of the slider 12 through threaded rotation, and the inner end of the locking bolt 14 is set to contact the right side wall of the slide rail 11; loosen the locking bolt 14, adjust the position of the slider 12 on the slide rail 11, and at the same time, read the spacing between adjacent positioning plates 13 through the scale layer 10, so as to facilitate the precise adjustment of the spacing between adjacent adjustment plates 5.

[0031] The working principle of this specific embodiment is as follows: before electrophoretic coating, the spacing between adjacent booms 8-10 is adjusted by understanding the size of the workpiece to be coated; during adjustment, when the adjustment plate 5 needs to be moved upward, the adjustment plate 5 is directly pushed upward, and the buckle 7-5 slides on the limit rod 7-1. When it is adjusted to the appropriate position, due to the gravity of the adjustment plate 5 itself, the sleeve 7-2 tends to move downward on the limit rod 7-1. At this time, the buckle 7-5 is stuck on the limit rod 7-1, and the sleeve 7-2 cannot move downward; when the adjustment plate 5 needs to be moved downward, the buckle 7-5 is rotated so that the buckle 7-5 is disengaged from the through hole on the sleeve 7-2, and the sleeve 7-2 drives the adjustment plate 5 to move downward on the limit rod 7-1, and the adjustment is completed. When the buckle 7-5 is released, the torque of the No. 1 torsion spring 7-6 presses the buckle 7-5 against the outer wall of the limit rod 7-1; when it is necessary to adjust the left and right spacing between the hanging arms 8-10 on the front side wall of the adjusting plate 5, the elastic steel sheet 8-7 on the adjusting seat 8-5 that needs to be adjusted is rotated around the No. 2 rotating shaft 8-6, and the positioning rod 8-8 is inserted into the inside of the limit hole 8-9. At this time, the screw rod 8-3 is rotated, and the nut block 8-4 drives the adjusting seat 8-5 to adjust the left and right position on the No. 2 guide rod 8-2, and the remaining unfixed nut blocks 8-4 are rotated with the screw rod 8-3, and their positions remain unchanged; after the adjustment is completed, the workpiece is hung on the hanging arm 8-10, and the entire device is hung in the electric swimming pool through the hanging ring 2 for painting.

[0032] After adopting the above structure, the beneficial effects of this specific implementation are:

[0033] 1. The height between the upper and lower adjustment plates 5 is adjusted by the height adjustment mechanism 7, so as to adjust the distance between the upper and lower suspension arms 8-10, and the adjustment method is relatively simple and easy to operate;

[0034] 2. Rotate the screw rod 8-3, fix the screw nut block 8-4 and the adjustment seat 8-5 through the positioning rod 8-8, and adjust the spacing between the adjacent suspension arms 8-10 brackets, thereby adjusting the spacing between the workpieces on the left and right sides, which is easy to operate; at the same time, multiple or single adjustment seats 8-5 can be selectively adjusted, which increases the flexibility of the device;

[0035] 3. Under the torsion of the No. 2 torsion spring 18, the arm 8-10 rotates around the No. 3 rotating shaft 17, so that the arm 8-10 is close to the connecting rod 15, reducing the space occupied by the arm 8-10; when the arm 8-10 is in use, the workpiece is hung at the end of the arm 8-10, and the arm 8-10 is placed on the limit plate 19;

[0036] 4. The distance between adjacent positioning plates 13 is read out through the scale layer 10, so as to facilitate accurate adjustment of the distance between adjacent adjustment plates 5.

5. The electrophoretic coating rack that is easy to adjust in height according to claim 4, characterized in that: The upper side surface of the suspension arm (8-10) is fixedly provided with clamping grooves (20) at equal intervals; when a workpiece is hung on the suspension arm (8-10), the clamping grooves (20) effectively prevent the workpiece from sliding on the suspension arm (8-10).

6. The electrophoretic coating rack that is easy to adjust in height according to claim 1, characterized in that: Its working principle is as follows: before electrophoretic coating, the spacing between adjacent booms (8-10) is adjusted by understanding the size of the workpiece to be coated; when adjusting, when the adjustment plate (5) needs to be moved upward, the adjustment plate (5) is directly pushed upward, and the buckle (7-5) slides on the limit rod (7-1). When it is adjusted to an appropriate position, due to the weight of the adjustment plate (5), the sleeve (7-2) tends to move downward on the limit rod (7-1). At this time, the buckle (7-5) is stuck on the limit rod (7-1) and the sleeve (7-2) cannot move downward; when the adjustment plate (5) needs to be moved downward, the buckle (7-5) is rotated so that the buckle (7-5) is disengaged from the through hole on the sleeve (7-2), and the sleeve (7-2) drives the adjustment plate (5) to move downward on the limit rod (7-1). When the adjustment is completed, the buckle (7-5) is released. The buckle (7-5) and the torque of the first torsion spring (7-6) push the buckle (7-5) against the outer wall of the limit rod (7-1); when it is necessary to adjust the spacing between the hanging arms (8-10) on the front side wall of the adjustment plate (5) to the left and right, the elastic steel sheet (8-7) on the adjustment seat (8-5) to be adjusted is rotated around the second rotation axis (8-6), and the positioning rod (8-8) is inserted into the inside of the limit hole (8-9). At this time, the screw rod (8-3) is rotated, and the nut block (8-4) drives the adjustment seat (8-5) to adjust the left and right position on the second guide rod (8-2), and the remaining unfixed nut blocks (8-4) rotate with the screw rod (8-3) and remain in the same position; after the adjustment is completed, the workpiece is hung on the hanging arm (8-10), and the entire device is hung in the electric swimming pool through the hanging ring (2) for painting.
