Description

Technical Field

[0001] The present invention relates to the technical field of luggage production, and in particular to a luggage drawbar laser processing device used in luggage production. Background Art

[0002] Luggage usually refers to portable containers with loading and storage functions and equipped with movable parts. Its core structure includes a rigid or semi-rigid box, an opening and closing system, a load-bearing mechanism and a moving component. The moving components of modern luggage generally use a drawbar as the core load-bearing component. This component is generally composed of multiple nested tubes. In the processing of luggage drawbar blanks, laser cutting equipment is widely used due to its advantages such as high cutting precision and fast speed.

[0003] In existing technology, after laser cutting, the tie rod blanks are dropped directly onto the processing table. Due to the height difference between the cutting station and the table, the ends of the tie rod raw material are subjected to impact loads, resulting in localized plastic deformation and adversely affecting subsequent assembly accuracy. Furthermore, the fallen tie rods need to be manually collected piece by piece, which reduces the production efficiency of luggage tie rods. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the prior art, the present invention provides a laser processing equipment for luggage rods used in luggage production, which can effectively solve the problem in the prior art that the cut pull rods fall directly onto the processing table. Since there is a certain height difference between the cutting station and the table, this height will cause the end of the pull rod raw material to be subjected to impact load, thereby causing local plastic deformation, which will adversely affect the subsequent assembly accuracy.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides a luggage drawbar laser processing device for luggage production, comprising:

[0007] A frame located below the laser cutting unit;

[0008] The frame is rotatably connected to a rotating shaft via a bearing seat arranged on its outer side, and the rotating shaft is fixedly connected to a cutting frame via a mounting plate arranged on its outer surface. The cutting frames are provided with a plurality of them and are distributed in an array along the center of the mounting plate. A clamping piece for fixing the pull rod is provided inside the cutting frame. A grinding piece for grinding both ends of the pull rod is provided inside the cutting frame. A collecting rack for collecting the pull rod is provided on the outer side of the frame.

[0009] When the rotating shaft drives the cutting frame to deflect along its central axis, the cutting frame can tilt and remain flush with the material collection frame, so that the cut pull rod automatically slides into the material collection frame under the action of its own gravity.

[0010] Furthermore, it also includes a driving member arranged outside the frame, the driving member includes a driving motor fixedly connected to the frame, and the driving motor is connected to the end of the rotating shaft through a transmission mechanism arranged at its output end.

[0011] Furthermore, the material collection rack includes a material guide part and a collecting part. The material guide part and the collecting part are an integrally formed structure. The material guide part is designed to be inclined, and the side of the material guide part away from the collecting part is fixedly connected to the outside of the frame. The inner walls of the collecting part and the material guide part are both provided with flexible rubber pads.

[0012] Furthermore, the grinding piece includes guide holes opened on the outside of the cutting frame, and the guide holes are provided in two groups and are symmetrically distributed along the center of the cutting frame. The guide holes include inclined holes and horizontal holes that are connected to each other. A guide rod is slidably connected in the guide hole, and a grinding block is provided on the opposite surface of the guide rod in the same group.

[0013] Furthermore, the cutting frame is slidably connected to a movable block through a slide groove opened on its outside, and the movable block is connected to the inner wall of the slide groove through a return spring arranged on its outside. A movable rod is slidably connected to the inside of the movable block, and a push block that fits the outer surface of the guide rod is fixedly connected to the top of the movable rod, and the push block is connected to the outer surface of the guide rod through a magnetic part arranged on its inner wall.

[0014] Furthermore, a slot is formed on the top of the cutting frame, and the slot includes an open slot and a through hole that are interconnected;

[0015] A T-shaped frame is slidably connected in the through hole, and a movable plate connected to the outer side of the movable block is rotatably connected to the bottom of the T-shaped frame. A sliding hole is opened inside the T-shaped frame, and a counterweight plate that fits the inner wall of the sliding hole is slidably connected in the open groove, and the top of the counterweight plate is designed with an inclined surface. The cutting frame is connected to the outer side of the counterweight plate through an elastic member arranged on its top.

[0016] Furthermore, the grinding block includes a fixed block fixedly connected to the outer surface of the guide rod, and the fixed block is rotatably connected to a fitting block through an annular groove opened inside it, and a fitting groove is opened on the side of the fitting block close to the pull rod, and the inner wall of the fitting groove is designed to be a rough surface.

[0017] Furthermore, the fixed block is rotatably connected to a rotating rod connected to the outside of the bonding block, and the rotating rod is fixedly connected to a gear at one end away from the bonding block. The guide rod is slidably connected to a rack engaged with the gear through a U-shaped frame arranged on its outer surface, and one side of the rack is designed with a bevel.

[0018] Furthermore, the cutting frame is slidably connected to a counterweight frame that fits the rack slope through a guide rail arranged inside it, and the counterweight frame is connected to the inner wall of the guide rail through a compression spring arranged on the outside, and the contact surface between the counterweight frame and the guide rail is designed to be a rough surface.

[0019] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] The present invention is provided with a grinding piece, which drives the cutting frame to tilt to be flush with the material collection frame through a rotating shaft. Based on the principle of gravitational potential energy conversion, the pull rod's own gravity is used to achieve unpowered sliding, eliminating the height difference impact of traditional free fall. The tilt angle of the material collection frame guide part is optimized to make the pull rod slide smoothly along the tangential direction. Combined with the elastic buffer of the flexible rubber pad on the inner wall, the impact energy is absorbed by deformation, avoiding plastic deformation of the end and ensuring assembly accuracy. In addition, during the material cutting process, the friction coefficient of the contact surface between the counterweight frame and the guide rail is greater than the friction coefficient between the counterweight plate and the open slot, ensuring first feeding and then rotation. Through the differentiated design of the material surface roughness and contact pressure, the counterweight plate starts to slide first under a smaller gravitational force component to complete the positioning and fitting of the grinding block. When the tilt angle is further increased and the force component on the counterweight frame exceeds the greater friction force, the rack movement and the fitting block rotation are triggered to achieve grinding of the two ends of the pull rod and improve the surface finish.

The contact surface between the counterweight frame 58 and the guide rail is designed to be a rough surface.

[0046] The working principle and advantages of the luggage drawbar laser processing equipment used in luggage production:

[0047] Tie rod cutting process:

[0048] During the actual operation process, the operator transfers the tie rod blank to the cutting frame 3 through the external conveying mechanism. When the tie rod blank moves to the set workstation on the cutting frame 3, the clamping part 4 will position and clamp the tie rod blank to prevent the subsequent laser cutting unit from performing cutting operations on the tie rod blank. The workpiece will be displaced and the cutting accuracy will be affected.

[0049] After positioning and clamping the tie rod blank, the operator uses an external moving mechanism to move the laser cutting unit to the cutting station. The laser cutting head within the laser cutting unit then begins cutting the tie rod blank according to pre-set process parameters. Once the cutting operation is complete, the laser cutting unit returns to its original position along a predetermined trajectory. Clamps 4 maintain a secure grip on the tie rod to prevent the finished workpiece from falling directly from cutting frame 3 onto the work surface and causing damage.

[0050] Tie rod end grinding process:

[0051] After the cutting process is completed, the built-in drive of the frame 1 drives the shaft 2 and the cutting frame 3 to rotate around the central axis of the shaft 2 to a preset grinding angle, so that the cutting frame 3 is tilted and forms a specific angle with the horizontal plane. During this process, the movement of the grinding member 5 includes two stages:

[0052] As the inclination angle of the cutting frame 3 increases, the downward force acting on the counterweight plate 57 gradually increases. When this force exceeds the static friction between the counterweight plate 57 and the open slot, the counterweight plate 57 slides relative to the open slot, stretching the elastic member. Because the top of the counterweight plate 57 is designed as a sloped structure, and the top of the internal sliding hole 562 of the T-shaped frame 56 is provided with a matching inclined surface, the linear motion of the counterweight plate 57 is converted into upward displacement of the T-shaped frame 56 along the through hole by utilizing the vertical height difference between the lowest and highest ends of the counterweight plate 57's inclined surface through the inclined surface transmission pair. In conjunction with the dual movable plates 561 at the bottom of the T-shaped frame 56, the movable block 54 is simultaneously pulled toward the center of the cutting frame 3, causing it to move in the opposite direction along the slide slot. The movable block 54 is internally installed with a freely slidable movable rod 541, and its top push block 542 is magnetically connected to the guide rod 52 through the inner wall magnetic element. When the two movable blocks 54 on the same side move toward each other, the guide rod 52 drives the grinding block 53 to perform linear motion along the guide hole 51.

[0053] Guide hole 51 is composed of a horizontal hole connected to an inclined hole. As guide rod 52 moves with push block 542, it first drives grinding block 53 along the inclined hole toward the pull rod. When guide rod 52 reaches the horizontal hole section, the center axis of grinding block 53 coincides with the center axis of the pull rod. As guide rod 52 continues to move, the mating grooves 533 in grinding block 53 achieve surface contact and mating with the ends of the pull rod.

[0054] It is worth noting that the contact surface between the counterweight frame 58 and the guide rail has been subjected to friction-increasing treatment, and its friction coefficient is greater than the friction coefficient between the counterweight plate 57 and the open groove, ensuring that the counterweight plate 57 meets the critical sliding condition while the counterweight frame 58 remains stationary.

[0055] When the inclination angle of the cutting frame 3 increases to the preset grinding angle, the downward force component on the counterweight frame 58 exceeds the maximum static friction force on the contact surface with the guide rail, and enters the critical sliding state and produces linear displacement along the guide rail. During the movement of the counterweight frame 58, its inclined surface is squeezed into contact with the inclined surface of the rack 536, pushing the rack 536 to slide horizontally along the U-shaped frame. Since the rack 536 and the gear 535 form a meshing transmission pair, the linear motion of the rack 536 is converted into the rotational motion of the gear 535, and the mating block 532 is driven to rotate synchronously through the rotating rod 534. By utilizing the large transmission ratio characteristics between the rack 536 and the gear 535, the high-speed rotation of the mating block 532 in the fixed block 531 is achieved, and the two ends of the pull rod are polished through the rough inner wall of the mating groove 533 to remove cutting burrs.

[0056] It's worth noting that the cross-section of the fitting groove 533 is trapezoidal, creating a multi-dimensional contact surface. When the grinding block 53 moves linearly along the guide hole 51 to a fitted state, the two sides of the trapezoidal fitting groove 533 form angled contact surfaces with the end of the pull rod, while the bottom side forms a planar contact with the end face, creating a three-dimensional constrained contact system. This structure distributes the normal pressure during grinding gradiently along the height of the trapezoidal cross-section, avoiding stress concentration caused by single-point or line contact and reducing local wear rates.

[0057] Tie rod blanking process:

[0058] After the grinding process is completed, the driving part cooperates with the rotating shaft 2 to drive the cutting frame 3 to continue rotating to the preset angle for unloading, so that the cutting frame 3 is flush with the inclined part of the material collection rack 11. At this time, the guide rod 52 and the grinding block 53 close to the material collection rack 11 overcome the adsorption force between the guide rod 52 and the magnetic part of the push block 542 under the action of their own gravity, and the push block 542 separates and slides to the initial position along the inclined hole of the guide hole 51. Due to the height difference of the inclined hole, the grinding block 53 is at the lowest position in the cutting frame 3 after being reset, maintaining the maximum height difference with the pull rod to avoid interfering with the movement of the pull rod. At the same time, the clamping part 4 gradually loosens the pull rod, allowing it to slide down to the material collection rack 11 under the action of its own gravity. The flexible rubber pad set inside the material collection rack 11 can prevent the pull rod from being damaged by rigid collision, thereby ensuring the quality of subsequent assembly.

[0059] After the drawbar slides down to the collection rack 11, the driver resets the cutting rack 3 to its horizontal initial position. During this reset, the downward force of the counterweight plate 57 gradually decreases, causing the elastic member on the cutting rack 3 to return to its initial position. The counterweight plate 57 then resets, and the T-shaped rack 56 moves downward along the through-hole. The movable block 54, under the action of the external return spring, resets the push block 542 and reattaches it to the guide rod 52. The guide rack, simultaneously reset to its initial position by the compression spring, thus achieving a continuous processing cycle for the drawbar blank.

[0060] The present invention adopts the grinding piece 5, which has the following advantages:

[0061] Advantage 1: Gravity-driven automatic unloading mechanism prevents impact deformation. Rotating shaft 2 drives cutting frame 3 to tilt flush with material collection rack 11. Based on the principle of gravitational potential energy conversion, the pull rod's own weight achieves unpowered sliding, eliminating the height difference impact of traditional free fall. The optimized tilt angle of the material collection rack 11 guide allows the pull rod to slide smoothly along the tangent direction. Combined with the elastic cushioning of the flexible rubber pad on the inner wall, the deformation absorbs impact energy, preventing plastic deformation at the end and ensuring assembly accuracy.

[0062] The second advantage is that the multi-station array cutting frame 3 improves processing efficiency. Multiple cutting frames 3 are distributed in a circumferential array on the mounting plate, and multi-station cycle processing is realized in conjunction with the rotation of the rotating shaft 2. By matching the speed of the driving motor with that of the transmission mechanism, the cutting frame 3 passes through the loading, cutting, grinding, and unloading stations in sequence to form a continuous processing line. The parallel operation of multiple stations shortens the single batch processing cycle, which is beneficial to improving the production efficiency of the pull rod.

[0063] Advantage three: the friction coefficient between the contact surface of the counterweight frame 58 and the guide rail is greater than the friction coefficient between the counterweight plate 57 and the open groove, ensuring first feeding and then rotation. Through the differentiated design of material surface roughness and contact pressure, the counterweight plate 57 starts sliding first under a smaller gravity component force to complete the positioning and fitting of the grinding block 53. When the inclination angle is further increased and the component force received by the counterweight frame 58 exceeds the greater friction force, the rack 536 is triggered to move and the fitting block 532 is rotated, avoiding the risk of interference in synchronous movement and ensuring the orderly execution of the grinding process.

[0064] Advantage four: the fitting groove 533 adopts a trapezoidal cross-section, forming a three-dimensional constraint system with inclined contact on the two waist sides and flat contact on the bottom side. The trapezoidal cross-section makes the grinding pressure decrease gradually along the height direction, avoiding stress concentration of single-point contact. Through the multi-dimensional surface contact between the fitting block 532 and the end of the pull rod, the grinding area is expanded and the normal force is evenly distributed. Combined with the micro-cutting effect of the rough surface of the inner wall of the fitting groove 533, the cutting burrs are efficiently removed while reducing the local wear rate.

[0065] Advantage five: The inclined surface of rack 536 rotates gear 535, achieving high-speed rotation and grinding of bonding block 532 through a large transmission ratio. Based on the meshing transmission principle of gear 535 and rack 536, the linear motion of rack 536 is converted into rotational motion of gear 535, and the differential number of teeth creates a speed-increasing effect. The increased rotation speed of bonding block 532 enhances the grinding linear velocity. Combined with the optimized friction coefficient of the rough surface, kinetic energy is converted into grinding energy, effectively removing molten residue and micro-bumps from the cut edge of the drawbar, improving surface finish.

[0066] Advantage six: the magnetic part on the inner wall of the push block 542 is magnetically connected to the guide rod 52. When the cutting frame 3 is tilted to the unloading angle, gravity overcomes the magnetic force to separate the two, and the grinding block 53 is reset to the low position. By utilizing the vector superposition principle of the magnetic attraction of the magnetic material and the gravity, the magnetic force maintains the stable position of the grinding block 53 during normal processing. In the unloading stage, the gravity component of the guide rod 52 along the inclined hole is greater than the magnetic attraction, realizing non-contact automatic separation and ensuring that the sliding path of the pull rod is unobstructed.
