Description

Technical Field

[0001] The utility model relates to the technical field of aluminum tube processing, in particular to a square aluminum tube feeding device. 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 square aluminum tubes as the installation carrier of PTC heating elements. When square aluminum tubes are processed as heater accessories, it is usually necessary to drill holes in the square tubes during the processing of the square aluminum tubes. When drilling holes in the square tubes, the operator usually pushes the square tubes to feed the punching machine. After the punching machine drills holes in the square tubes, the aluminum tubes are manually flipped over again, and the square tubes are moved under the punching machine so that the punching machine can drill holes in the square tubes again. This method is complicated to operate and requires operators to cooperate with each other, which wastes manpower and reduces production efficiency. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a square aluminum tube feeding device, comprising an operating table, a conveying table is arranged at the head end of the operating table, and a turning assembly and a pushing assembly installed at both ends of the turning assembly are installed on the top of the operating table, and a clamping assembly is installed at both ends of the turning assembly;

[0005] The clamping assembly includes two push-down cylinders hinged at the bottom of the operating table and two U-shaped blocks fixed thereto. The ejection ends of the two push-down cylinders are respectively hinged with clamping hooks and clamping rods hinged to the two U-shaped blocks and extending out of the operating table surface.

[0006] Furthermore, the flip assembly includes a frame plate slidably connected to the operating table and extending downward, and a propulsion cylinder installed at the bottom and connected to the frame plate. The inner side of the frame plate is rotatably connected to two rotating drums and a belt drive device is installed that is transmission-connected to the two rotating drums.

[0007] Furthermore, the pushing assembly includes a support frame fixed on the operating table and located at the head end of the rotating drum and a front pushing cylinder at the tail end, a pushing plate is fixed to the ejection end of the front pushing cylinder, a feeding cylinder is installed at the bottom of the support frame, a lower ejection cylinder slidably connected to the support frame is fixed to the ejection end of the feeding cylinder, and an adsorption block is fixed to the ejection end of the lower ejection cylinder.

[0008] Furthermore, a frame body located at the rear end of the flip assembly is fixed on the top of the operating table, an ejection cylinder is installed on one side of the frame body, and a pressure plate is fixed to the ejection end of the ejection cylinder.

[0009] Furthermore, a bottom plate is fixed at the bottom of the operating table, an oblique thrust cylinder is installed on one side of the bottom plate, and a limit block slidably connected to the bottom plate is fixed at the ejection end of the oblique thrust cylinder.

[0010] Furthermore, a stopper distributed opposite to the bottom of the clamping hook and a plurality of guide plates arranged at the head end of the flip assembly are fixed to the bottom of the operating table.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The square aluminum tube feeding device moves three groups of aluminum tubes to be aligned with the flipping assembly through a conveying table. When each group moves and aligns, the pushing assembly pushes the aluminum tubes toward the flipping assembly until one group of aluminum tubes is positioned between the clamping assemblies to complete the punching operation. The aluminum tubes can be returned to the rotating drum to complete the flipping through the cooperation of the pushing assembly and the conveying table. The above operation is repeated to complete the feeding and punching on the other side. When unloading, the cooperation of the pushing assembly and the conveying table can push the aluminum tubes one by one onto the conveying table for transportation. Therefore, automatic loading and unloading and flipping operations can be realized, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

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 1-4 A square aluminum tube feeding device in this embodiment includes an operating table 1, a conveying table 2 is installed at the head end of the operating table 1, the conveying table 2 is a partition type conveyor, and a flip component 3 and a pushing component 4 installed at both ends of the flip component 3 are installed on the top of the operating table 1, as well as two groups of clamping components 6 between the two tail ends of the flip component 3 and the tail end pushing component 4.

[0020] In the above structure, the conveyor table conveys the aluminum tube and retracts to leave space for the aluminum tube to retract. Then, with the cooperation between the pushing component and the conveyor table, the aluminum tube can be driven to move to the operating table, the flipping component and the clamping component in sequence to complete the loading operation. At the same time, the unloading operation of the aluminum tube can be completed through the cooperation between the pushing component and the conveyor table. In this process, the flipping operation of the aluminum tube can also be completed in cooperation with the flipping component, thereby realizing automatic loading and unloading and flipping operations.

[0021] like Figure 2 The clamping assembly 6 includes two sets of push-down cylinders 601 that are relatively distributed and hinged at the bottom of the operating table 1, and two sets of U-shaped blocks 602 are fixed, one of which is two, and the ejection ends of the two push-down cylinders 601 are respectively hinged with clamping hooks 604 and clamping rods 605 that are hinged with the two U-shaped blocks 602 and extend from the table surface of the operating table 1, and the clamping hooks 604 and the clamping rods 605 are relatively distributed. When the aluminum tube moves between the clamping hooks and the clamping rods, the two push-down cylinders operate simultaneously, thereby being able to drive the clamping hooks and the clamping rods to clamp and position the aluminum tube, so that the external punching machine can complete the punching operation.

[0022] Among them, a frame 501 located at the tail end of the flip assembly 3 is fixed on the top of the operating table 1, and two ejection cylinders 502 are fixedly installed on one side of the frame 501 away from the tail end of the flip assembly 3. A pressing plate 503 is fixed to the ejection end of the ejection cylinder 502, and the bottom concave surface of the pressing plate 503 is trapezoidal. When the aluminum tube comes out of the flip assembly, the pressing plate is driven down to a certain height by the ejection cylinder. Under the action of the concave surface of the pressing plate, the aluminum tube can be corrected to avoid displacement and dislocation during movement. After the aluminum tube moves to the appropriate position, the pressing plate is pressed down by the ejection cylinder to be positioned, and the clamping hook and the clamping rod are used to position it, so that the firmness of the aluminum tube when punching and fixing can be effectively improved.

[0023] In addition, a bottom plate 606 is fixed to the bottom of the operating table 1, and an oblique push cylinder 607 is installed on the side of the bottom plate 606 away from the flip assembly 3. A limit block 608 slidably connected to the bottom plate 606 is fixed to the ejection end of the oblique push cylinder 607, and the limit block 608 can extend to the top of the operating table 1. When the aluminum tube is pushed between the clamp hook and the clamp rod by the end push assembly, the oblique push cylinder drives the limit block to be ejected and extended to the top of the operating table until the aluminum tube is attached to the limit block, so that the aluminum tube can be limited by the limit block, so that the aluminum tube can be moved to a suitable position.

[0024] like Figure 3 The flip assembly 3 includes a frame plate 301 that is slidably connected to the operating table 1 and extends to the bottom, and a propulsion cylinder 302 that is installed at the bottom and connected to the frame plate 301. The inner side of the frame plate 301 is rotatably connected to two rotating drums 303 and a belt driving device 304 that is installed on the frame plate 301 and is transmission-connected to the two rotating drums 303. The inner side of the rotating drum 303 is square. When the aluminum tube is pushed into the rotating drum through the pushing assembly, the inner side of the rotating drum is square and can limit the square aluminum tube. At the same time, the rotating drum is driven to rotate by the belt driving device, so as to adjust the flipping of the aluminum tube. When the aluminum tube is pushed to one side, the propulsion cylinder will drive the frame plate to move, so that the two openings of the rotating drum are aligned with the surface of the operating table respectively.

[0025] like Figure 1 and 4 The pushing assembly 4 includes a support frame 401 fixed on the table of the operating table 1 and located at the head end of the rotating drum 303, and a forward pushing cylinder 7 at the tail end. A pushing plate 8 is fixed to the ejection end of the forward pushing cylinder 7. A feeding cylinder 402 is installed at the bottom of the support frame 401. A lower ejection cylinder 403 is fixed to the ejection end of the feeding cylinder 402, which is slidably connected to the support frame 401. An adsorption block 404 is fixed to the ejection end of the lower ejection cylinder 403. Two protruding adsorption heads are formed at the bottom of the adsorption block 404. When the conveying table, the lower ejection cylinder, the adsorption block and the feeding cylinder cooperate to realize the three-stage feeding operation, the aluminum tube is first transported to the rotating drum through the conveying table, and the lower ejection cylinder drives the adsorption block to adsorb the aluminum tube, and pushes it to the operating table through the feeding cylinder, resets, and then the conveying table transports a new group of aluminum tubes to align with the aluminum tubes. After repeating the above two operations, the aluminum tubes on the operating table enter the rotating drum and are pushed between the clamping hook and the clamping rod to realize the feeding operation;

[0026] At this time, there are aluminum tubes in the drum and on both sides of the drum mouth. When the rightmost aluminum tube needs to be turned over, the forward push cylinder drives the push plate to advance halfway, so that the rightmost aluminum tube is pushed into the drum, and the aluminum tube in the drum is pushed out onto the operating table, and the aluminum tube on the operating table is re-entered onto the conveying table. The drum rotates to complete the turning of the aluminum tube, and then the above operation is repeated again to complete the feeding. When the remaining surfaces need to be punched, continue to repeat the above operation;

[0027] When discharging, the forward push cylinder drives the push plate to be pushed out as a whole, thereby pushing the aluminum tube between the clamp hook and the clamp rod into the rotating drum, and at the same time passing through the rotating drum until the aluminum tube is located on the operating table. During the pushing process, the aluminum tube on the far left is pushed to the conveying table, and the conveying table retreats. The processed aluminum tube on the far right pushes the middle aluminum tube back to the conveying table, and the conveying table retreats. Then the feeding cylinder drives the adsorption block to be located above the aluminum tube, and the lower top cylinder drives the adsorption block to adsorb the aluminum tube, and drives the aluminum tube to be moved to the conveying table through the return of the feeding cylinder, and then transported through the conveying table, and then the above operation is repeated to complete the automatic loading and unloading of the aluminum tube, and at the same time cooperate with the feeding operation of the aluminum tube flipping.

[0028] The bottom of the operating table 1 is fixed with a stopper 603 which is distributed relative to the bottom of the clamping hook 604, and three guide plates arranged at the head end of the flip assembly 3. The stopper can block the clamping hook, thereby limiting the position of the clamping hook to prevent the clamping hook from being excessively moved by the push-down cylinder. At the same time, under the action of the guide plate, it can play a guiding and limiting role when pushing the aluminum tube, and can prevent deviation during the pushing process.

[0029] The working principle of the above embodiment is:

[0030] The aluminum tube is transported by the conveying table to be aligned with the guide plate, and the lower push cylinder drives the adsorption block to adsorb the two aluminum tubes, and the aluminum tube is driven to move between the guide plates by the feeding cylinder, and the conveying table continues to transport, and then the above-mentioned pushing is repeated, and the aluminum tube enters the guide plate, and the aluminum tube at the guide plate enters the rotating drum, and the conveying table continues to transport. The aluminum tube is guided to push the aluminum tube in the rotating drum to between the clamping hook and the clamping rod. At the same time, the oblique push cylinder drives the limit block to lift up, and the ejection cylinder drives the pressure plate to move down to guide the aluminum tube until the aluminum tube contacts the limit block. The ejection cylinder drives the pressure plate to press the aluminum tube, and at the same time, the downward push cylinder drives the clamping hook and the clamping rod to clamp the aluminum tube and position it to complete the punching operation;

[0031] When the aluminum tube needs to be turned over, the forward push cylinder drives the push plate to advance half of the process, thereby pushing the punched aluminum tube into the rotating drum, the aluminum tube in the rotating drum is moved out and the aluminum tube on the operating table is moved to the conveying table, and then the belt drive device drives the rotating drum to rotate, thereby mobilizing the aluminum tube to turn over. After the turning is completed, the lower top cylinder drives the adsorption block to adsorb the two aluminum tubes, and the aluminum tube in the rotating drum is pushed between the clamping hook and the clamping rod by the aluminum tube pushing method to complete the punching of the other side. The above-mentioned pushing cylinder cooperates with the above-mentioned feeding to drive the frame plate to move left and right to fine-tune and align the barrel mouth of the rotating drum with the operating tables on both sides;

[0032] When punching is completed and material is required to be unloaded, the forward push cylinder drives the push plate to push it out as a whole. The processed aluminum tube is on the far right, and the far right aluminum tube will be pushed directly between the guide plates. Therefore, during the pushing process, the middle aluminum tube drives the far left aluminum tube to be pushed to the conveyor table. At this time, the conveyor table retreats to leave retreat space, and the far right aluminum tube pushes the middle aluminum tube to the conveyor table. The conveyor table retreats again, and then the feeding cylinder drives the adsorption block to be located above the far right aluminum tube, and the lower top cylinder drives the adsorption block to stick to and adsorb the aluminum tube, and then the rightmost cylinder is moved to the conveyor table by the feeding cylinder, and then it is transported through the conveyor table to complete the unloading operation.

[0033] In summary, the loading, unloading and flipping of aluminum tubes can be automated, thereby reducing manual labor and improving production efficiency.
