Technical Field

[0001] The utility model relates to the technical field of aluminum tube processing, in particular to an internal coating device for an aluminum tube. Background Art

[0002] In the field of new energy vehicle technology, electric vehicles generally use power battery packs as a power source. Unlike fuel engines, electric vehicles do not have a power device that generates heat sources, and cannot provide heat sources to power battery packs. At the same time, they cannot provide the warm air heat source required for air conditioning, defrosting, etc. Therefore, electric vehicles must rely on electricity to use PTC heaters for heating.

[0003] PTC heaters usually use aluminum tubes as the installation carrier of PTC heating elements. When aluminum tubes are processed as heater accessories, materials usually need to be sprayed on the inner wall of the aluminum tube during the processing. The common spraying method is to use a handheld spray gun to manually spray the inner wall of each aluminum tube. The above method not only has low work efficiency, but also manual spraying during the spraying process will make the inner wall of the aluminum tube unevenly sprayed. In addition, the sprayed material has certain toxicity, and direct contact has certain hazards to the environment and human body. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 In this embodiment, an internal coating device for an aluminum tube comprises an operating table 1 and a conveying device 2 on which a bearing block for conveying the aluminum tube is installed. A positioning component 5 and a moving component 4 for fixing the bearing block and the aluminum tube are installed on the upper surface of the table top of the operating table 1. Two groups of rotating cylinders 406 are installed on the moving end of the moving component 4. A nozzle 6 that can extend to the inside of the aluminum tube is installed on the rotating end of the rotating cylinder 406. A threaded block is fixed to the bottom of the rotating cylinder 406, and the top of the nozzle is threadedly connected to the threaded block. The nozzle pipe of the nozzle 6 is provided with spray holes arranged equidistantly from top to bottom.

[0020] In the above structure, the carrier block is pushed and moved by the conveying device, so that the aluminum tube with the carrier block can be pushed to the top of the positioning component, and the positioning of the carrier block and the aluminum tube is completed by the positioning component to avoid movement during spraying and affecting the spraying effect. The moving component drives the nozzle to extend to the inside of the aluminum tube and rotates through the rotating cylinder. Under the spraying of the spray hole, the material can be evenly sprayed on the inner wall of the aluminum tube.

[0021] In order to realize the movement of the nozzle, the moving assembly 4 includes a frame 401 fixed on the operating table 1, a propulsion cylinder 402 is installed on the left side of the frame 401, a propulsion plate 403 sliding on the frame 401 is fixed to the ejection end of the propulsion cylinder 402, a push-down cylinder 404 is installed on the top of the propulsion plate 403, a push-down plate 405 sliding on the propulsion plate 403 is fixed to the ejection end of the push-down cylinder 404, and two groups of rotating cylinders 406 are installed on the push-down plate 405. The propulsion cylinder drives the push-down plate to move, so that the nozzle moves longitudinally until the nozzle is located above the aluminum tube, and the operation of the push-down cylinder drives the push-down plate to move, so that the nozzle of the nozzle extends to the inside of the aluminum tube, so as to realize the movement of the nozzle.

[0022] At the same time, a cleaning tank 3 is installed on the operating table 1 near the conveying device 2 and on the same axis as the nozzle 6. The moving assembly can drive the nozzle to move to the cleaning tank to complete the cleaning of the nozzle, thereby preventing the sprayed paint from clogging the spray hole and affecting the quality of the spraying.

[0023] Among them, in order to achieve the nozzle to move down to a suitable position, a limit cylinder is installed on the left side of the push plate 403, and a limit plate is fixed on the left side of the push-down plate 405. The protruding end of the limit block is provided with a U-shaped notch, and the push rod of the limit cylinder is located in the U-shaped notch, and the limit block is fixed at the bottom end of the push rod, and the diameter of the limit block is larger than the diameter of the U-shaped notch. The limit block is driven to move down to a suitable position by the limit cylinder, and then when the push-down cylinder drives the push-down plate to move down, it will also drive the limit plate to move down until the limit plate contacts the limit block, thereby limiting the continuous downward movement of the push-down plate, so that when the nozzle is driven to move down, it can be ensured that the nozzle of the nozzle can be prevented from moving down too much to break the nozzle, and at the same time, it can be prevented from moving down too little to cause uneven spraying.

[0024] In addition, in order to remove the nozzle, a replacement assembly 7 is installed on the table of the operating table 1. The replacement assembly 7 includes a side plate 701 fixed on the operating table 1, a front push cylinder 704 and a clamping cylinder 705 connected to the ejection end of the front push cylinder 704 are installed on the left side of the side plate 701, and a clamping plate 706 is fixed to the clamping end of the clamping cylinder 705, and a semicircular hole is opened on the opposite side of the clamping plate 706. When the moving assembly drives the nozzle to move to the semicircular hole of the clamping plate, the nozzle is clamped and fixed by driving the two clamping plates through the clamping cylinder, and then the nozzle is rotated by the rotating cylinder until the nozzle is separated from the thread block, and then the removed nozzle is moved to a certain place for placement by cooperating with the front push cylinder, and the new nozzle is clamped and moved to the bottom of the thread block, and the connection is completed by rotating placement, thereby realizing the removal and replacement of the nozzle.

[0025] At the same time, an upper cylinder 702 is installed on the right side of the side plate 701, and a top plate 703 is fixed to the ejection end of the upper cylinder 702. The forward cylinder 704 is installed on the left side of the top plate 703, and the clamping cylinder 705 is slidably installed on the top of the top plate 703 and fixedly connected to the ejection end of the forward cylinder 704. When there is no need to replace the nozzle, after the nozzle spraying is completed, the nozzle is lifted to a certain height by the moving assembly, and the forward cylinder drives the clamping cylinder to move, so that the nozzles of the two nozzles are both located in the semicircular hole, and the clamping cylinder drives the clamping plate to close, and then pushes up through the upper cylinder, so that the residue on the outside of the nozzle can be peeled off to avoid clogging the nozzle hole caused by adhering to the outer wall of the nozzle.

[0026] The positioning assembly 5 includes an upward push cylinder 501 installed at the bottom of the operating table 1. Two positioning pins 502 that can extend to the inside of the conveying device 2 are installed on the upward push end plate of the upward push cylinder 501. The bottom of the bearing block is provided with a plurality of positioning holes that match the positioning pins 502. When the bearing block is transported to the bottom of the nozzle by the conveying device, the positioning pins are lifted up by the upward push cylinder and extended to the bottom positioning holes of the bearing block, so that the bearing block can be positioned.

[0027] In addition, the positioning assembly 5 also includes an upper plate 503 fixed on the operating table 1, a clamping cylinder 504 is installed at the bottom of the upper plate 503, and a positioning plate 505 is fixed to the clamping end of the clamping cylinder 504. The lower surface of the positioning plate 505 is not on the same horizontal plane as the lower surface of the clamping cylinder 504, and two pairs of trapezoidal notches are opened on the opposite sides of the two positioning plates 505. When the above-mentioned push-up cylinder drives the positioning pin to position the bearing block, the positioning pin will also drive the bearing block to position, and the lifted bearing block will drive the aluminum tube to be located between the two positioning plates, and then under the action of the clamping cylinder, the two positioning plates are driven to close, and the clamping and positioning of the aluminum tube is completed at the trapezoidal notch, and then the bearing block is pushed forward by resetting, and the above-mentioned operation is repeated to complete the positioning and transportation.

[0028] The working principle of the above embodiment is:

[0029] The conveyor belt carries the load-bearing block through the conveying device until the load-bearing block drives the aluminum tube to be located above the positioning pin, and the upward push cylinder drives the positioning pin to extend into the positioning hole of the load-bearing hole, and at the same time lifts the load-bearing block so that the aluminum tube is located between the positioning plates, and the positioning plates are driven by the clamping cylinder to clamp and position the aluminum tube, thereby completing the positioning of the load-bearing block and the aluminum tube, and then the thrust cylinder drives the thrust plate to move the nozzle above the aluminum tube, and the limit cylinder drives the limit block to the appropriate position in advance, and when the push-down cylinder drives the push-down plate to move downward, the limit plate will also be driven downward until the limit plate and the limit block are connected, so that the nozzle of the nozzle can be moved down to the appropriate position, and then the rotating cylinder drives the nozzle to rotate, so that the material can be evenly sprayed on the inner wall of the aluminum tube, thereby realizing automatic spraying, reducing manual contact, and reducing the harm to manual labor.

[0030] When spraying is completed, the push-down cylinder drives the nozzle to retreat to a certain height, and the forward push cylinder drives the clamping cylinder forward until the nozzle is located between the clamping plates. The clamping cylinder drives the clamping plates to clamp the nozzle, and then the upper cylinder operates. Therefore, during the upward movement of the clamping plates, the impurities attached to the nozzle can be peeled off to prevent the attached impurities from clogging the nozzle hole. At the same time, with the cooperation of the forward cylinder and the push-down cylinder, the nozzle can be moved to the cleaning pool for cleaning, thereby increasing the service life of the nozzle. When the nozzle needs to be replaced, the nozzle is clamped by the clamping plates, and then the nozzle and the threaded block are separated by the rotation of the rotating cylinder, thereby automatically removing the nozzle.
