Description

Technical Field

[0001] This invention relates to the field of aluminum tube cutting technology, and more specifically, to an aluminum tube cutting device for tent frame production. Background Technology

[0002] Tent frames are typically made up of aluminum tubes of various sizes. Therefore, the aluminum tubes need to be cut to the required size according to the needs. In order to ensure the stability of the frame and the accuracy of the assembly, the aluminum tubes need to be cut precisely to ensure that the cut aluminum tubes meet the requirements. A suitable cutting device can greatly reduce waste, avoid waste, and improve the utilization rate of materials.

[0003] Currently, the clamps in aluminum tube cutting devices used for tent frame production on the market are mostly simple top-and-bottom or left-and-right clamping structures, which leads to the following technical problems during use: When clamping, it is difficult to ensure that the central axis of the aluminum tube is precisely aligned with the feed direction of the cutting tool, which can easily lead to misalignment of the aluminum tube. When cutting, the cut of the misaligned aluminum tube is prone to tilting and unevenness. At the same time, most existing cutting devices use external clamping when clamping the end of the aluminum tube, that is, clamping from the outside of the tube wall. Although the external clamping method is simple in structure, for aluminum tubes that need to keep the outer wall intact (such as tent frames that need to be painted or decorated), the jaws can easily leave indentations or scratches on the tube wall surface, affecting the appearance of the product. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an aluminum tube cutting device for tent frame production that can convert horizontal movement into synchronous centering and clamping action of two sets of positioning plates, combined with V-shaped pressure grooves, to achieve automatic centering and clamping of aluminum tubes without the need for repeated centering adjustments, thus avoiding clamping deviation problems and providing a positioning basis for subsequent precise cutting.

[0011] The invention is further configured such that: a multi-stage hydraulic telescopic cylinder electrically connected to the controller is fixed on one side of one of the side baffles, and a through hole coaxially arranged with the multi-stage hydraulic telescopic cylinder is opened on one side of the other side baffle; a T-slot is opened on the top of the base, and a guide crossbar is fixed on one side of the other side baffle above the through hole; a sliding plate is fixed on one outer side of the rectangular frame and slidably fitted inside the T-slot, and the sliding plate and the guide crossbar are slidably fitted through, and a second sleeve is fixed on one side of the sliding plate and sleeved and fixed to the telescopic end of the multi-stage hydraulic telescopic cylinder.

While reducing the form and position tolerance of the cutting section, it also reduces the number of repeated interventions and adjustments in the later stage, thereby improving production efficiency and batch cutting consistency.

[0032] Example 1, please refer to Figures 1-11The present invention provides the following technical solution: an aluminum tube cutting device for tent frame production, specifically comprising a support mechanism 1 and a cutting positioning mechanism 2. The cutting positioning mechanism 2 includes a support member 3 and an end member 4 threaded onto the support member 3. The cutting positioning mechanism 2 also includes a cutting member 5 slidably fitted onto the support member 3 and a clamping member 6 slidably fitted onto the cutting member 5. The cutting member 5 includes a U-shaped frame 501 slidably fitted onto the support member 3. A U-shaped horizontal plate 502 is fixed to each of the two inner side walls of the U-shaped frame 501. A rectangular frame 503 is fixed to the top of the U-shaped frame 501. Two base plates 504 are fixed to one side of the rectangular frame 503. A vertical rod 50 is fixed to the top and bottom surfaces of each of the two base plates 504. 5. The vertical rods 505 located on the upper and lower sides of the same base plate 504 are coaxially arranged; the clamping component 6 includes two slide rails 601 that are slidably fitted on two U-shaped horizontal plates 502 respectively. A push plate 602 is fixed on one side of each slide rail 601. Two symmetrical oblique grooves 603 are opened through one side of the push plate 602. The clamping component 6 also includes two sets of positioning plates 604 that are symmetrically fitted on the upper and lower vertical rods 505 of the base plate 504 respectively. A corresponding V-shaped pressure groove 605 is opened on the two sets of positioning plates 604. A rubber protective pad is fixed on the inner wall of the V-shaped pressure groove 605. A toggle rod 606 that is slidably fitted inside the oblique groove 603 is fixed on the side of each set of symmetrically arranged positioning plates 604 facing the push plate 602. Each set of positioning plates 604 consists of two plates, symmetrically arranged vertically. A sliding hole 607 is formed at the top of each positioning plate 604, slidably engaging with the vertical rod 505. Two symmetrically arranged limiting grooves 608 are formed on the inner wall of the sliding hole 607. Linear ball bearing assemblies for reducing impedance and off-center load are embedded in the inner walls of both the sliding hole 607 and the limiting grooves 608. Two limiting vertical rails 506 are fixed to the circumference of the vertical rod 505, each slidably engaging with the linear ball bearings inside the two limiting grooves 608. The two sliding rails 601 are located on one side of the push... Each plate 602 has a first pin 609 fixed below it. The two first pins 609 are hinged to the sides of the two pivot arms 610. Each pivot arm 610 is rotatably connected to a second pin 611 on one side. Each second pin 611 has a lifting plate 612 fixed at its end. The bottom of the lifting plate 612 is fixed with a first fixing cylinder 613. The support member 3 includes a base 301. The top of the base 301 has two side baffles 302 fixed at intervals. One side baffle 302 has a controller 303 fixed on one side. The bottom of the U-shaped frame 501 has a first telescopic cylinder 507 that is electrically connected to the controller 303. The telescopic end of the first telescopic cylinder 507 is fixedly connected to the first fixing cylinder 613.

[0033] The specific application of this embodiment is as follows: In the initial state, the first telescopic cylinder 507 is in the retracted state, and the lifting plate 612 is driven to a low position through the first fixed cylinder 613. The lifting plate 612 is connected to the rotating arm 610 via the second pin 611, and the other end of the rotating arm 610 is connected to the slide rail 601 via the first pin 609. At this time, the slide rail 601 and the push plate 602 are located on the outer side of the U-shaped horizontal plate 502. The inclined groove 603 on the push plate 602 pulls the two sets of positioning plates 604 away from each other through the actuating rod 606, that is, the two sets of positioning plates 604 are in the open state, and the distance between the V-shaped pressure grooves 605 is greater than the outer diameter of the aluminum tube to be cut, which facilitates the insertion of the aluminum tube to be cut. The diameter of the aluminum tube to be cut is in the range of 20-50mm. During the initial feeding stroke, the aluminum tube to be cut passes along the main axis through two sets of positioning plates 604 at their maximum opening until it reaches the end reference position. The specific structure and working principle of the end component 4 are described in Embodiment 2. When clamping is required later, the controller 303 responds to the trigger signal and actuates the first telescopic cylinder 507 to extend. Here, the horizontal thrust of the first telescopic cylinder 507 is... The inclination angle is The inclined slot 603 performs mechanical vector conversion and outputs a high-frequency synchronous vertical clamping force component. (satisfies the relation) This creates a highly stable V-shaped centering reference at the physical execution layer, thereby pushing the lifting plate 612 upward. The lifting plate 612 drives the lower end of the rotating arm 610 to rise via the second pin 611. The upper end of the rotating arm 610 pushes the slide rail 601 along the U-shaped horizontal plate 502 inward, i.e., towards the direction of the aluminum tube to be cut, via the first pin 609. This forces the push plate 602 to move along the linear displacement of the slide rail 601, causing the actuating rod 606 to overcome static friction and slide along the inclined groove 603. Ultimately, this forces the two sets of positioning plates 604 to simultaneously press against the outside of the aluminum tube to be cut. Since the inclined groove 603 is inclined, its inclination angle is set to... The preferred parameter range This included angle range ensures a limited amount of horizontal drive displacement. Below, it can be effectively converted into a vertical synchronous displacement that meets the compatibility requirements of various pipe diameters. and satisfy the formula To prevent the device from locking itself due to the thrust component, the groove wall exerts an inward and simultaneously inward thrust on the actuating rod 606. The actuating rod 606 is fixed to each positioning plate 604, so the two sets of positioning plates 604 slide relative to each other along the vertical rod 505 under the drive of the actuating rod 606, causing the upper positioning plate 604 to move downward and the lower positioning plate 604 to move upward. The V-shaped grooves 605 on the two sets of positioning plates 604 move towards the center of the aluminum tube to be cut simultaneously from both top and bottom directions, ultimately clamping the aluminum tube between the V-shaped grooves 605. The rubber protective pads fixed to the inner wall of the V-shaped grooves 605 are made of anti-slip rubber with a high coefficient of friction, and the surface of the rubber pads has micro anti-slip textures. Its hardness is set to Shore A 60-70 degrees, which can increase the friction to prevent the aluminum tube from slipping during the cutting process, and avoid direct contact with the outer wall of the aluminum tube to be cut, thus avoiding indentation. The sliding holes 607 on the positioning plates 604 slide in conjunction with the vertical rod 505. The limiting groove 608 in the sliding hole 607 cooperates with the limiting vertical rail 506 on the vertical rod 505. At the same time, the inner walls of the sliding hole 607 and the limiting groove 608 are both embedded with linear ball bearing assemblies for reducing resistance and off-center load. This allows the two limiting vertical rails 506 fixed on the circumferential side of the vertical rod 505 to slide and cooperate with the two limiting grooves 608 through the linear ball bearing assemblies. This ensures that the positioning plate 604 can only move smoothly in the vertical direction and will not rotate or shift. This ensures that the upper and lower V-shaped pressure grooves 605 are always accurately aligned, realizing automatic centering and clamping of the aluminum tube to be cut. Once the dual rigid locking state of the middle and end sections of the aluminum tube to be cut is confirmed, the main program in the controller 303 immediately adaptively issues the cutting feed sequence, linking the second telescopic cylinder 510 and the cutting motor 514 to perform a seamless cutting operation. The cutting action is completed by components such as the second telescopic cylinder 510, the cutting motor 514, and the cutting electric saw 515, as detailed in Embodiment 2. After the cutting is completed, the controller 303 controls the first telescopic cylinder 507 to retract, the lifting plate 612 to descend, and the rotating arm 610 to pull the slide rail 601 and the push plate 602 outward in the opposite direction. The inclined groove 603 pulls the upper and lower positioning plates 604 apart through the toggle rod 606, and the V-shaped pressure groove 605 releases the cut aluminum tube, allowing the cut tube to be removed and the next aluminum tube to be cut to be placed in. In summary, during the entire cutting process, the horizontal sliding is converted into the synchronous centering and clamping action of the upper and lower positioning plates 604 by the extension and retraction drive of the first telescopic cylinder 507, and the transmission conversion through the rotating arm 610, slide rail 601, push plate 602, inclined groove 603 and actuating rod 606. The V-shaped pressure groove 605 realizes the automatic centering and clamping of the aluminum tube to be cut, eliminating the need for repeated subsequent centering adjustments, improving clamping accuracy and efficiency, and providing a reliable positioning basis for subsequent cutting.

[0034] Example 2, please refer to Figures 1-11This second embodiment is an improvement on the first embodiment as follows: Specifically, two symmetrical threaded posts 304 are fixed to the top of the base 301; the end component 4 includes a column 401 threaded onto the two threaded posts 304, an L-shaped plate 402 is fixed to one side of the column 401, a first motor 403 electrically connected to the controller 303 is fixed to one outer side of the L-shaped plate 402, and a drive gear 404 is fixed to the output shaft of the first motor 403; a connecting shaft 405 is fixed to one side of the column 401 above the L-shaped plate 402, and a rotating disk 406 is rotatably fitted to the circumferential side of the connecting shaft 405, with the end of the rotating disk 406 penetrating through. A plurality of inclined slots 407 are provided. An expanded diameter circular plate 408 is fixed to the end of the connecting shaft 405 away from the rotating disk 406. A plurality of straight slots 409 are provided through one end face of the expanded diameter circular plate 408. I-shaped sliders 410 are slidably fitted inside each of the straight slots 409. An extension plate 411 is fixed to one side of each of the I-shaped sliders 410. A gripper plate 412 is fixed to one side of each of the extension plates 411. A flexible rubber plate 413 is fixed to one side of each gripper plate 412. A gear ring 414 meshing with a drive gear 404 is fixed to the opposite end face of the rotating disk 406. The I-shaped sliders 410 are fixed to the opposite side... Each surface is fixed with levers 415 that slide within several inclined slots 407; one side of one side baffle 302 is fixed with a multi-stage hydraulic telescopic cylinder 305 electrically connected to the controller 303, and another side baffle 302 has a through hole 306 coaxially arranged with the multi-stage hydraulic telescopic cylinder 305; a T-slot 307 is provided on the top of the base 301, and a guide crossbar 308 is fixed above the through hole 306 on one side of the other side baffle 302; a sliding plate 508 is fixed on one outer side of the rectangular frame 503, slidingly engaged within the T-slot 307, and the sliding plate 508 and the guide crossbar 308 are connected through... A sliding fit is provided, and a second sleeve 509 is fixed to one side of the sliding plate 508 and sleeved to the telescopic end of the multi-stage hydraulic telescopic cylinder 305; a second telescopic cylinder 510 electrically connected to the controller 303 is fixed to the top inside the rectangular frame 503; two symmetrical guide rods 511 are fixed to the top inside the rectangular frame 503; a cutting mounting plate 512 is slidably fitted between the two guide rods 511; a motor mounting plate 513 is fixed to one side of the cutting mounting plate 512; a cutting motor 514 electrically connected to the controller 303 is fixed to one side of the motor mounting plate 513; and a cutting electric saw 515 is provided on the output shaft of the cutting motor 514.

[0035] The specific application of this second embodiment is as follows: In the first embodiment, the rear part of the aluminum tube to be cut is clamped by the positioning plate 604, while the front end of the aluminum tube to be cut needs to be assisted by the end component 4 for clamping and centering to prevent the tube end from shaking during cutting. In the initial state, the first motor 403 is in standby mode. The relative angle between the rotating disk 406 and the expanding circular plate 408 causes the I-shaped slider 410 to be located on the radial inner side of the straight groove 409, that is, multiple gripper plates 412 move closer to each other. After they are closed, the outer diameter is smaller than the inner diameter of the aluminum tube to be cut. Then, the start controller 303 starts the first motor 403, drives the gear 404 to rotate, and drives the gear ring 414 meshing with it to rotate. The gear ring 414 is fixed on the rotating disk 406, so the rotating disk 406 starts to rotate relative to the connecting shaft 405. The inclined groove 407 on the rotating disk 406 also rotates, and the groove wall of the inclined groove 407 pushes the lever 415, causing the I-shaped slider 410 to slide radially outward along the straight groove 409 on the expanded diameter circular plate 408. The I-shaped slider 410 drives the gripper plate 412 to expand outward synchronously through the extension plate 411. As multiple gripper plates 412 expand evenly from the center outwards, the flexible rubber plates 413 on their outer sides gradually contact and internally support and press against the inner wall of the aluminum tube to be cut. The flexible rubber plates 413 are made of anti-slip rubber with a high coefficient of friction, which can increase the internal support friction to prevent the tube end from slipping, and avoid direct contact between the metal grippers to prevent indentations. Since all gripper plates 412 move radially in sync, automatic centering and clamping of the end of the aluminum tube to be cut is achieved. After the cutting is completed, the first motor 403 rotates in the opposite direction, driving the gear 404 to drive the gear ring 414 and the rotating disk 406 to reverse, and the inclined groove 407 pushes the lever 415 to make the I-shaped slider 410 slide radially inwards. The gripper plates 412 release the inner wall of the cut aluminum tube, thereby removing the tube. To meet the cutting requirements of aluminum tubes of different lengths or to achieve continuous fixed-length cutting, the cutting component 5 can move axially on the support component 3. The specific axial movement process is as follows: the controller 303 controls the extension or retraction of the multi-stage hydraulic telescopic cylinder 305. The multi-stage structure is used to achieve a larger extension stroke within the compact space of the base 301, thus accommodating the cutting of aluminum tubes of different lengths from 0.5m to 2m. The extension end of the multi-stage hydraulic telescopic cylinder 305 is fixedly connected to the sliding plate 508 via the second sleeve 509. The bottom of the sliding plate 508 slides within the T-slot 307, and the upper part of the sliding plate 508 is fixedly connected to the outer bottom of the rectangular frame 503. The sliding plate 508 also slides through the guide crossbar 308. When the multi-stage hydraulic telescopic cylinder 305 is activated, the sliding plate 508 slides horizontally along the T-slot 307 and the guide bar 308, thereby driving the entire cutting component 5, including the U-shaped frame 501, clamping component 6, second telescopic cylinder 510, cutting motor 514, etc., to move axially along the aluminum tube to be cut, achieving precise adjustment of the cutting position. The guide bar 308 and the T-slot 307 together ensure the straightness and stability of the movement, preventing deviation during the cutting process. When adjusting the cutting position, the software system in controller 303 first sends a command to release the clamping member 6 from the middle and rear clamping state of the positioning plate 604. The system only maintains the inner cantilever positioning constraint of the end gripper plate 412. Subsequently, the software system in controller 303 drives the multi-stage hydraulic telescopic cylinder 305 to smoothly slide the cutting part 5 to the preset cutting position. After reaching the target position, the software system executes a second clamping command to close the positioning plate 604. After completing the double centering and fixing, the cutting operation is then performed. During the later stages of the cutting operation: the cutting motor 514 is started by controller 303. The output shaft of the cutting motor 514 drives the cutting electric saw 515 to rotate. At the same time, controller 303 controls the second telescopic cylinder 510 to extend. The telescopic end of the second telescopic cylinder 510 pushes the cutting mounting plate 512 to slide vertically downward along the two guide rods 511. The cutting mounting plate 512 drives the motor mounting plate 513, cutting motor 514, and cutting saw 515 to descend synchronously, causing the rotating cutting saw 515 to contact the outer wall of the aluminum tube to be cut. During the continuous descent, the radial cut of the aluminum tube is completed. The guide rod 511 ensures the vertical feed trajectory of the cutting saw 515, preventing tilting and uneven cuts. After cutting, the second telescopic cylinder 510 retracts, lifting the cutting mounting plate 512 and cutting saw 515 upwards to reset. At this time, the cutting motor 514 stops running or remains ready for the next cut.
