Description

Technical Field

[0002] The body refers to the part of the vehicle used to carry people and cargo, and also refers to the vehicle as a whole. The main function of the car body is to protect the driver and create a good aerodynamic environment. In terms of form, the car body structure is mainly divided into two types: non-load-bearing and load-bearing.

[0003] Generally, a car body has three pillars, which are the front pillar, the middle pillar, and the rear pillar from the front to the back. For a car, the pillars not only play a supporting role, but also play a role of a door frame. In the process of processing the pillars, in order to prevent the surface of the pillars from being corroded, the pillars are usually coated by a coating device. For example, a Chinese patent (Announcement No.: CN219129732U) discloses a surface processing device for mechanical processing of a car body, including a base, a top end of the base is fixedly connected to a protective cover, a top end of the base is fixedly connected to a box, and one side of the box is fixedly connected to A feed pipe is connected, a discharge pipe is fixedly connected to one side of the box body, a hydraulic push rod is fixedly connected to the inner top wall of the protective cover, a fixed plate is fixedly connected to the output end of the hydraulic push rod, a guide rod is fixedly connected to the top of the fixed plate, and a motor is fixedly connected to the top of the fixed plate. The surface processing equipment for mechanical processing of automobile bodies can make the surface processing equipment have good processing efficiency, and the column is rotary dip-coated, which not only effectively improves the coating efficiency of the column, but also avoids the precipitation of the coating, thereby improving the practicability of the surface processing equipment to a certain extent.

[0004] The device drives the column to descend and be inside the box through a hydraulic push rod, then starts the motor to engage with the gears to promote the rotation of the column for painting, and finally realizes the drying operation of the paint through the cooperation of an electric fan. However, there are certain defects. After painting, the column is suspended vertically, and only the gravity factor is used to achieve the dripping of excess paint, and the position of the electric fan cannot be adjusted during the blowing operation, resulting in a low drying efficiency and reducing the progress of the work.

DETAILED DESCRIPTION

[0036] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 2 and Fig.10 In this embodiment, a surface processing equipment for automobile body mechanical processing includes a box body 1, a switch door 5 is hinged on the front of the box body 1, an observation window for observing the internal drying situation is inlaid on the front of the switch door 5, a door handle is fixed on the front of the switch door 5, a heating plate 3 is fixed to the rear side wall of the inner cavity of the box body 1, and a second tooth plate 4 is fixed at the lower ends of the left and right sides of the inner cavity of the box body 1, and a conveying mechanism 15 extending to its inner cavity is provided at the bottom of the box body 1, and the inner cavity of the box body 1 is movably connected with a liquid box 13 located on the conveying mechanism 15, and handles are fixed on the left and right sides of the top of the liquid box 13. The left side of the bottom of the liquid box 13 is fixedly connected with a drain pipe 14 extending to the outside of the box body 1, and a solenoid valve is fixed on the drain pipe 14.

[0038] Among them, the conveying mechanism 15 is composed of a base plate 151 and a linear module 152. The bottom of the linear module 152 is fixed with a mounting base with one end fixed to the bottom of the box body 1. The movable part of the linear module 152 extends to the inner cavity of the box body 1 and is fixed with the base plate 151. The top of the base plate 151 is provided with four slots. The bottom of the liquid tank 13 is fixed with four blocks engaged with the slots. The top of the base plate 151 is engaged with the liquid tank 13 through the slots and the blocks. The drain pipe 14 passes through the base plate 151 and the box body 1 from top to bottom in sequence and extends to the outside of the box body 1. The bottom of the box body 1 is provided with a long through groove for the drain pipe 14 to move, and the front of the long through groove is flush with the front of the box body 1.

[0039] The drain pipe 14 is connected to the external pipeline, and then the solenoid valve is started to facilitate the drain pipe 14 to discharge the liquid in the liquid tank 13. By opening the switch door 5, the liquid tank 13 is transported to the outside of the box body 1 through the linear module 152 on the transport mechanism 15, and then the liquid tank 13 is separated from the bottom plate 151 and replaced with a new spare tank. New coating liquid is injected into the spare tank for subsequent coating operations, and the replaced liquid tank 13 can be cleaned internally, thereby realizing the replacement of the dipping liquid and the cleaning of the liquid tank 13 as a whole.

[0040] Furthermore, four bases are fixed to the bottom of the box 1, and air holes are opened at the upper ends of the left and right sides of the box 1. Heating rods are fixed in the air holes. The left and right sides of the box 1 are detachably installed with filter screens located outside the air holes through threads. The filter screens can filter the gas entering the box 1. At the same time, the gas is preheated by the heating rod, and then the temperature in the box 1 is further increased by the heating plate 3, so as to increase the temperature in the box 1 and facilitate the drying operation.

[0041] A hydraulic cylinder 6 with a movable shaft extending to the inner cavity of the box body 1 is fixed on the top of the box body 1, and a dipping mechanism 7 for painting the automobile pillars is provided on the movable shaft of the hydraulic cylinder 6.

[0042] The left and right sides of the box body 1 are fixedly connected with an extension box 2, and a displacement mechanism 10 is provided on the inner wall of the extension box 2. The top wall and the bottom wall of the inner cavity of the extension box 2 are fixed with fixing rods 8. A drying mechanism 9 for drying the automobile pillars is fixed between the upper and lower fixing rods 8. The drying mechanism 9 is connected to the displacement mechanism 10, and the displacement mechanism 10 can drive the adjustment of the length of the drying mechanism 9.

[0043] It can be understood that the column is fixed by the dipping mechanism 7, and the hydraulic cylinder 6 is started to drive the column to descend and enter the liquid tank 13 for painting. While starting the dipping mechanism 7 to cause the column to rotate back and forth, the paint in the liquid tank 13 can be mixed through the transmission of the internal structure, which accelerates the liquid flow rate of the paint as a whole, avoids the sedimentation of the paint, and also increases the painting effect on the surface of the column.

[0044] In addition, it can be known that the displacement mechanism 10 drives the drying mechanism 9 to approach the surface of the column after painting, so that the drying path is shortened and the drying effect is enhanced, and then the drying mechanism 9 is started to effectively dry the surface of the column, and the drying mechanism 9 can adjust the amount of drying air according to the special shape of the drying machine, thereby further improving the efficiency of characteristic drying.

[0045] It is necessary to explain that the inner cavity of the extension box 2 is provided with a stabilizing structure, which is connected to the displacement mechanism 10. The stabilizing structure is used to increase the stability of the operation of the displacement mechanism 10. There are two groups of stabilizing structures, and each group of stabilizing structures has two stabilizing structures. Each stabilizing structure is composed of a stabilizing rod 11 and a stabilizing block 12. The two ends of the stabilizing rod 11 are respectively fixed to the fixed rod 8 and the inner wall of the extension box 2. The outer side of the stabilizing rod 11 is slidably connected to a stabilizing block 12 whose end is fixed to the displacement mechanism 10.

[0046] See also Figures 3 to 4 In order to achieve effective coating on the surface of the automobile pillar, the dipping mechanism 7 in this embodiment is composed of a fixed plate 71 fixed to the movable shaft of the hydraulic cylinder 6, a fixed component 72 and a stirring component 73. The fixed component 72 is used to fix the automobile pillar. The stirring component 73 cooperates with the fixed component 72 to effectively stir the coating liquid in the liquid tank 13, thereby achieving effective infiltration of the coating liquid on the pillar and avoiding the sedimentation of the coating. The bottom of the fixed plate 71 is fixed to the fixed component 72. The fixed component 72 is provided with a stirring component 73 whose one end is fixed to the bottom of the fixed plate 71. The fixed component 72 will cause the stirring component 73 to move and rotate during the driving process.

[0047] The fixing assembly 72 includes a servo motor 721 fixed to the bottom of the fixing plate 71, a rotating rod 722 is fixed to the output shaft of the servo motor 721, a connecting box 723 is fixed to the bottom of the rotating rod 722, a threaded rod 724 which penetrates the outside of the connecting box 723 on the right side is rotatably connected to the left wall of the inner cavity of the connecting box 723 through a bearing, a disc 725 is fixed to the right side of the threaded rod 724, and two symmetrically distributed moving blocks 726 are threadedly connected to the outer surface of the threaded rod 724, and two sections of threaded strips with opposite thread rotation directions are fixed to the outer surface of the threaded rod 724, and the inner sides of the two moving blocks 726 are provided with corresponding threaded strips. The bottom of the movable block 726 passes through the outside of the connecting box 723 and is fixed with a hook 727. The automobile pillar is hung by the hook 727, and the hook 727 is adapted to the hanging hole opened on the automobile pillar. Therefore, during the hanging and rotating immersion process, the automobile pillar can be stably connected to the hook 727, thereby increasing the stability during painting. The left and right sides of the bottom of the connecting box 723 are provided with limiting long holes for the movable block 726 to pass through. The limiting long holes can limit the movable block 726 from rotating together with the threaded rod 724, thereby pushing the two movable blocks 726 to translate relative to or opposite to each other under the threaded connection force.

[0048] It can be understood that by rotating the disc 725 to drive the threaded rod 724 to rotate, the limiting long hole limits the position, causing the two moving blocks 726 to translate relative to or away from each other, thereby realizing the adjustment of the distance of the hook 727, which is convenient for adapting to the fixing work of different types of columns. When the column is completely immersed in the liquid tank 13, the servo motor 721 is started to drive the rotating rod 722 to rotate, so that the automobile column hung on the hook 727 can be driven to rotate after being immersed in the liquid tank 13, thereby promoting the effective infiltration of the paint and the surface of the automobile column. At the same time, the paint in the liquid tank 13 is also stirred through the rotation operation to prevent the paint from settling.

[0049] The cam 732 is provided with two drive channels, and the drive channels are in a curved arc state. The drive channels are movably connected with drive posts 733 at both ends extending to the outside of the cam 731. When the cam 731 rotates with the cam 722, the drive channels are also driven to rotate. Since the limit posts 734 and the limit plates 732 limit the position of the drive posts 733, the force of the drive channel rotation is transmitted to the drive posts 733, prompting the drive posts 733 to move horizontally, thereby driving other structures and the stirring rod 736 to move horizontally, so as to facilitate the stirring of the stirring rod 736 during the subsequent expansion movement. The limit plates 732 are fixed on the left and right sides of the cam 722 and at the bottom of the cam 731. The limit posts 734 are slidably connected on the inner side of the limit plates 732 with the top fixed to the drive posts 733.

[0050] It should be noted that the limiting column 734 is in an inverted T-shape, and an inverted T-shaped long groove matched with the limiting column 734 is opened on the top of the limiting plate 732. The setting of the T-shaped long groove increases the stability of the movement of the limiting column 734.

[0051] It is also necessary to explain that the stirring assembly 73 also includes a fixing frame 735 fixed to the top of the driving column 733. A mounting hole is opened on the inner side of the fixing frame 735, and a bearing is fixed in the mounting hole. The fixing frame 735 is rotatably connected to a stirring rod 736 with both ends extending to the outside thereof through the bearing. When the stirring rod 736 is driven to rotate by the meshing force of the gear 737, the bearing can eliminate the force of the rotation of the stirring rod 736 to prevent the fixing frame 735 from being affected by the rotation. A gear 737 is fixed to the outer surface of the stirring rod 736, and a first tooth plate 739 is meshed on the back side of the gear 737. A support rod 738 with one end fixed to the first tooth plate 739 is fixed to the bottom of the fixing plate 71.

[0052] It should be added that a fixing strip is fixed to one end of the first tooth plate 739 away from the support rod 738, and a fixing groove matching the fixing strip is opened on the second tooth plate 4, and the top surface of the fixing groove is flush with the top surface of the second tooth plate 4. Through a pre-set program, when the hydraulic cylinder 6 drives the dipping mechanism 7 to drop in height until the automobile pillar fixed on the hook 727 is completely immersed in the liquid tank 13, the fixing strip on the first tooth plate 739 is engaged with the fixing groove on the second tooth plate 4, so that the first tooth plate 739 is connected to the second tooth plate 4 to form a whole long strip, thereby extending the travel path of the gear 737, and then facilitating the lengthening of the path for the stirring rod 736 to rotate, thereby improving the stirring effect of the stirring rod 736 on the liquid.

[0053] In addition, the stirring rod 736 is composed of a thick rod and a thin rod. The thick rod passes through the fixing frame 735 and is fixed to the gear 737. The thin rod is fixed to the bottom of the thick rod, and a plurality of stirring blades are fixed to the outer surface of the thin rod.

[0054] See also Figures 5 to 9In order to accelerate the drying operation of the automobile mechanical surface, the drying mechanism 9 in this embodiment includes an air storage cylinder 91 fixed between the upper and lower fixing rods 8, and a heating strip 92 distributed in an annular manner is fixed on the inner wall of the air storage cylinder 91. A plurality of longitudinally equidistantly arranged positioning blocks 93 are fixed to the inner cavity of the air storage cylinder 91. The positioning blocks 93 are U-shaped, which can firmly fix the connecting pipe on the air outlet hose 97 to prevent the air outlet hose 97 from being separated from the positioning blocks 93 when being pulled and displaced. The outer surface of the air storage cylinder 91 is movably connected with an extension cylinder 94, and the inner wall of the extension cylinder 94 is fixed with a heating strip 92 distributed in an annular manner. There are four pushing blocks 95 slidingly connected to the outer surface of the air storage cylinder 91, and a side of the extension cylinder 94 facing the dipping mechanism 7 is fixedly connected to a plurality of nozzles 96 distributed in a circular array. The opposite sides of the nozzles 96 on the left and right sides extend into the extension cylinder 94 and are fixedly connected to an air outlet hose 97. The end of the air outlet hose 97 away from the nozzle 96 passes through the air storage cylinder 91 and is fixed to the positioning block 93. An air pump 99 is fixed to the side of the air storage cylinder 91 away from the extension cylinder 94, and an air inlet rod 910 that passes through the inner cavity of the air storage cylinder 91 is fixedly connected to the air outlet of the air pump 99.

[0055] It can be understood that the hot air flow in the box 1 is sucked in by the air pump 99 and transported from the air inlet rod 910 to the air storage cylinder 91, and the temperature of the hot air is preheated again by the heating strip 92. The hot air is then transmitted to the nozzle 96 by the air outlet hose 97, prompting the nozzle 96 to blow and dry the clamped and suspended automobile pillars, and the extension tube 94 can be driven to extend, so that the nozzle 96 can be closer to the position of the automobile pillar, thereby accelerating the drying efficiency.

[0056] Furthermore, a plurality of mounting grooves distributed in a ring shape are provided on the inner wall of the air storage cylinder 91, the heating strip 92 is fixed in the mounting groove, and four translation grooves for displacement of the push block 95 are provided on the outer surface of the air storage cylinder 91. The air outlet hose 97 is composed of a corrugated hose and a connecting pipe. The corrugated hose is fixedly connected to the nozzle 96, and a one-way valve 98 is fixed on the corrugated hose. The other end of the corrugated hose is fixedly connected to the connecting pipe. The corrugated hose has an extensible property, so that when the extension tube 94 is pushed and translated, the corrugated hose is stretched, and the connection between the corrugated hose and the connecting pipe will not be separated, thereby increasing the stability of the air outlet. The other end of the connecting pipe passes through the positioning block 93 and is fixed to the positioning block 93.

[0057] In addition, the displacement mechanism 10 includes an electric push rod 101 fixed to the inner wall of the extension box 2, and the movable axis of the electric push rod 101 is fixed with a movable plate 102. The top and bottom of the movable plate 102 are fixed with a driving rod 103 that passes through the fixed rod 8. The fixed rod 8 is provided with a through hole for the driving rod 103 to pass through. The driving rod 103 is L-shaped, and the driving rod 103 is fixed to the stabilizing block 12. A connecting plate 104 with one end fixed to the extension tube 94 is fixed to the side of the driving rod 103 away from the movable plate 102.

[0058] In this embodiment, the electric push rod 101 can drive the movable plate 102 to move, and under the transmission of force, it prompts the driving rod 103 to drive the connecting plate 104 to move, and then drives the extension tube 94 to be driven by the connecting plate 104 to move horizontally, so that the nozzle 96 located on the extension tube 94 can gradually approach the surface of the column, shortening the path of the drying gas spraying and increasing the drying effect.

[0059] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0060] The working principle of the above embodiment is:

[0061] (1) The disc 725 is rotated to adjust the relative position between the two moving blocks 726 so that the two hooks 727 can be fixed on the column, and then the hydraulic cylinder 6 is started to cause the overall height of the dipping mechanism 7 to drop, so that the column and the stirring rod 736 and other structures are immersed in the liquid tank 13. At this time, the first tooth plate 739 and the second tooth plate 4 are fully engaged, and then the servo motor 721 is started to cause the servo motor 721 to rotate back and forth to a certain extent, thereby driving the column to rotate in the coating liquid and mix the coating, thereby accelerating the wetting degree of the coating and the column surface. At the same time, the turntable 731 located on the outer side of the rotating rod 722 rotates forward and reversely. The driving column 733 on the left and right sides is driven to move back and forth in opposite directions and relative to each other through the driving channel, thereby driving the stirring rods 736 on both sides to follow the reciprocating movement. During the movement of the stirring rod 736, the gear 737 on its outer side moves on the first tooth plate 739 and the second tooth plate 4. Under the meshing force, the driving gear 737 and the stirring rod 736 with its axis fixed rotate and are connected as a whole, so that the stirring rod 736 can rotate while moving back and forth, effectively stirring the coating liquid, cooperating with the rotation operation of the column, accelerating the flow of the coating liquid, thereby avoiding the sedimentation of the paint, and further realizing the high efficiency of the surface coating of the instrument.

[0062] (2) After the surface coating of the machine is completed, the dipping mechanism 7 is lifted up as a whole by the hydraulic cylinder 6 and returned to its original position. Then the electric push rod 101 is started to push the movable plate 102 to drive the rod 103 to move, so that the extension tube 94 is driven to approach the surface of the column to facilitate close drying by air blowing. Then the air pump 99 is started to inhale the hot air in the box 1 and transport it to the air storage cylinder 91 through the air intake rod 910. According to the outer frame contour of the column, multiple one-way valves 98 corresponding to the contour can be started, and then the corresponding nozzles 96 can be opened to perform special-shaped jet drying operations. Since the number of nozzles 96 is reduced, the gas flow rate is enhanced, which further increases the drying efficiency. The overall structure is simple, and the nozzles 96 can be adjusted according to the different models of the machine surface, thereby increasing the adaptability and efficiency of the drying.

[0063] (3) When the coating liquid in the drain box 13 needs to be replaced, the drain pipe 14 is connected to the external pipeline, and then the solenoid valve is started to cause the liquid in the drain box 13 to be discharged, and then the switch door 5 is opened, and the conveying mechanism 15 is started, so that the movable part on the linear module 152 transports the bottom plate 151, causing the liquid box 13 located on the bottom plate 151 to be moved to the outside of the box body 1, and then the liquid box 13 is moved away from the bottom plate 151 and replaced with a new liquid box, and then the liquid box 13 is transported back to the box body 1 through the linear module 152 for subsequent operations, and the moved liquid box 13 can be cleaned. The overall structure is simple, and the replacement and cleaning of the liquid box 13 can be achieved.
