Description

Technical Field

[0001] This invention relates to the field of laser welding equipment technology, and in particular to a laser welding equipment with a clamping device. Background Technology

[0002] Laser welding technology, with its significant advantages such as high energy density, small heat-affected zone, fast welding speed and excellent weld quality, has been widely used in high-end manufacturing fields such as new energy vehicles, 3C electronics, aerospace, and rail transportation, becoming one of the core processing technologies driving the intelligent and precision upgrading of the manufacturing industry.

[0003] The laser welding equipment disclosed (Publication No.: CN211387347U) includes a substrate. A first guide frame is mounted on the top of the substrate. A guide block is sleeved on the outer wall of the first guide frame. A second guide frame is fixedly mounted on the left side of the guide block. A guide plate is movably mounted on the outer wall of the second guide frame. A guide rod is fixedly mounted on the left side of the guide plate, penetrating and extending to the left side of the second guide frame. A mounting base is fixedly mounted on the left side of the guide rod. A first servo motor is fixedly mounted on the left side of the mounting base. A fixing block is sleeved on the output shaft of the first servo motor. This laser welding equipment, by activating the second servo motor, drives the turntable, the first clamping plate, and the second clamping plate to rotate via the output shaft and connecting shaft, thereby facilitating the adjustment of the welding horizontal angle of the laser welding equipment and achieving a simple and convenient all-around adjustment effect.

[0004] In the aforementioned application, when workpiece clamping and positioning is achieved through the cooperation of the first clamping plate and the second clamping plate, it is difficult to solve the problem of flexible adaptation clamping function for workpieces of different thicknesses and shapes. This results in thin-walled parts and irregularly shaped parts being easily scratched or deformed by hard contact. At the same time, it cannot adapt to the clamping requirements of workpieces of various specifications, resulting in poor versatility and thus affecting the welding positioning accuracy and product qualification rate. Therefore, we propose a laser welding equipment with a clamping device. Summary of the Invention

[0005] The purpose of this invention is to provide a laser welding device with a clamping device, which solves the problem of existing flexible and adaptable clamping functions through the welding clamping mechanism.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a laser welding device with a clamping mechanism, comprising a base, a housing fixedly connected to the top of the base, a worktable fixedly connected to the top of the housing, control buttons on the side of the worktable, a support column fixedly connected to the top of the worktable, a sliding connecting seat slidably connected to the top of the support column, a lifting platform slidably connected to the top of the sliding connecting seat, welding fixtures fixedly connected to the side of the lifting platform, a display screen rotatably connected to the side of the support column, a drag chain fixedly connected to the side of the sliding connecting seat, and a welding clamping mechanism on the top of the worktable. The welding clamping mechanism includes a connecting plate, the side of which is fixedly connected to the side of the worktable. A motor is fixedly connected to the side of the connecting plate, and a drive gear is fixedly connected to the output shaft of the motor. A bidirectional screw is rotatably connected through the side of the worktable. A driven gear is fixedly connected to the top of the bidirectional screw, and the tail end of the bidirectional screw is rotatably connected to the inner wall of the worktable. A first pulley is fixedly connected to the circumferential surface of the bidirectional screw, and a connecting sleeve is threadedly connected to the circumferential surface of the bidirectional screw. A protective sleeve is fixedly connected to the top of the connecting sleeve, and a spring is fixedly connected to the inner wall of the protective sleeve. A pressure plate is fixedly connected to the end of the spring away from the inner wall of the protective sleeve, and a flexible bonding block is fixedly connected to the side of the pressure plate.

[0007] The driving gear meshes with the driven gear for transmission. Two pressure plates and two flexible bonding blocks are provided, symmetrically distributed along the vertical central axis of the bidirectional screw. The meshing of the driving and driven gears ensures the stability and accuracy of power transmission; the symmetrical distribution of the two pressure plates and two flexible bonding blocks along the vertical central axis of the bidirectional screw ensures uniform force on the workpiece, preventing workpiece displacement and guaranteeing welding accuracy.

[0008] The middle part of the pressure plate is inclined inward, and the pressure plate is slidably connected to the inner wall of the protective sleeve. The inward inclination of the middle part of the pressure plate can adapt to the clamping requirements of non-flat workpieces such as arc-shaped and irregular shapes. The slidable connection of the pressure plate to the inner wall of the protective sleeve makes the movement trajectory of the pressure plate stable and improves the smoothness and reliability of the clamping action.

[0009] The number of springs is set to eight, and they are distributed in a linear array on the inner wall of the protective sleeve. The bottom of the pressure plate is slidably connected to the top of the worktable. The interior of the worktable has a hollow structure, and several support bars are fixedly connected to the inner top wall. The eight springs are distributed in a linear array to provide uniform and adjustable buffer clamping force for the pressure plate, further reducing the risk of workpiece damage. The pressure plate is slidably connected to the top of the worktable to ensure the translation accuracy of the pressure plate during clamping. The hollow structure of the worktable, together with the support bars on the inner top wall, reduces the weight of the equipment while ensuring the load-bearing strength of the worktable, and facilitates the falling of welding debris.

[0010] The workbench is equipped with a debris cleaning device, which includes a reciprocating screw. Both ends of the reciprocating screw are rotatably connected to the inner wall of the workbench. A second pulley is fixedly connected to the circumferential surface of the reciprocating screw, and a belt is fitted onto the circumferential surface of the second pulley. A fixing plate is threaded onto the circumferential surface of the reciprocating screw, and a cleaning push plate is fixedly connected to the bottom of the fixing plate. A sliding groove is provided on the inner wall of the workbench, and the end of the cleaning push plate away from the fixing plate is slidably connected to the inner wall of the sliding groove.

[0011] The inner bottom wall of the workbench is provided with a groove, which is inclined, and an anti-splatter baffle is fixedly connected to the inner wall of the groove. The inclined groove on the inner bottom wall of the workbench can guide the debris to slide down quickly and avoid debris accumulation. The anti-splatter baffle on the inner wall of the groove can block the rebound of high-temperature debris splashed during welding and reduce the probability of debris residue.

[0012] The bottom of the cleaning push plate is located on the displacement trajectory of the inner bottom wall of the workbench, and the second pulley is connected to the first pulley via a belt. The bottom of the cleaning push plate covers the displacement trajectory of the inner bottom wall of the workbench, ensuring that there are no blind spots in debris cleaning; the second pulley is connected to the first pulley via a belt, realizing the power linkage between the welding clamping mechanism and the debris cleaning device, eliminating the need for an additional drive source and saving equipment costs and installation space.

[0013] The side of the box is provided with a debris collection device, which includes a high-pressure air pump. The side of the high-pressure air pump is fixedly connected to the side of the box. A collection box is fixedly connected to the bottom of the workbench. A nozzle is fixedly connected to the inner wall of the collection box. A second collection groove is opened on the inner wall of the box. A collection plate is slidably connected to the side of the box. An observation plate is rotatably connected to the side of the box. An air pipe is fixedly connected to the side of the nozzle.

[0014] The collecting plate is used to collect debris from the collecting box and the second collecting trough. The inner wall of the collecting box is inclined. The collecting plate can collect debris from the collecting box and the second collecting trough simultaneously, reducing the number of times debris is transferred. The inclined inner wall of the collecting box accelerates the sliding of debris onto the collecting plate, preventing debris from accumulating in the collecting box.

[0015] The nozzle is connected to a high-pressure air pump via an air pipe on its side. This direct connection ensures the stability and sufficient pressure of the purging airflow, improves the removal of residual debris, and prevents debris from affecting the quality of subsequent welding operations.

[0016] The present invention has the following beneficial effects: 1. The welding clamping mechanism of the present invention uses a combination structure of spring, pressure plate and flexible bonding block on the inner wall of the protective sleeve. The spring can automatically adjust the compression amount according to the size of the workpiece to generate an adaptive buffer clamping force. Combined with the soft contact characteristics of the flexible bonding block, it can avoid scratches and deformation of the workpiece caused by hard contact, and can adapt to workpieces of different thicknesses and shapes, greatly improving the versatility of the device.

[0017] 2. The debris cleaning device of the present invention uses a reciprocating screw to drive the fixed plate and the cleaning push plate to perform reciprocating linear motion. Combined with the design of the bottom of the cleaning push plate covering the full displacement trajectory of the inner bottom wall of the workbench, it can thoroughly clean the welding debris inside the workbench and avoid cleaning blind spots. Compared with manual cleaning, the automated cleaning method does not require interruption of welding operation, which greatly improves the overall operating efficiency of the equipment.

[0018] 3. The debris collection device of the present invention has a partitioned collection structure of a collection box and a second collection trough. Debris sliding down from the trough directly enters the collection box, while the second collection trough is specifically used to collect debris pushed by the cleaning pusher during the back and forth cleaning process. This achieves partitioned collection of debris from different sources, avoids debris from randomly scattering inside the device, and reduces pollution and blockage to the internal transmission components and circuit system of the device.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The driving gear 803 meshes with the driven gear 804 for transmission.

The meshing of the driving gear 803 and driven gear 804 ensures the stability and accuracy of power transmission; the symmetrical distribution of the two pressure plates 810 and two flexible bonding blocks 811 along the vertical central axis of the bidirectional screw 805 ensures uniform force on the workpiece clamping, prevents workpiece displacement, and guarantees welding accuracy.

[0026] The middle part of the pressure plate 810 is inclined inward, and the pressure plate 810 is slidably connected to the inner wall of the protective sleeve 808. The inward inclination of the middle part of the pressure plate 810 can adapt to the clamping requirements of non-flat workpieces such as curved and irregular shapes.

The interior of the worktable 3 has a hollow structure, and several support bars are fixedly connected to the inner top wall. The eight springs 809 are arranged in a linear array to provide uniform and adjustable buffer clamping force for the pressure plate 810, further reducing the risk of workpiece damage. The pressure plate 810 is slidably connected to the top of the worktable 3 to ensure the translation accuracy of the pressure plate 810 during clamping. The hollow structure of the worktable 3, together with the support bars on the inner top wall, reduces the weight of the equipment while ensuring the load-bearing strength of the worktable 3, and facilitates the falling of welding debris.

[0028] The workbench 3 is equipped with a debris cleaning device 9. The debris cleaning device 9 includes a reciprocating screw 901. Both ends of the reciprocating screw 901 are rotatably connected to the inner side wall of the workbench 3. A second pulley 902 is fixedly connected to the circumferential surface of the reciprocating screw 901. A belt 903 is sleeved on the circumferential surface of the second pulley 902. A fixing plate 904 is threadedly connected to the circumferential surface of the reciprocating screw 901. A cleaning push plate 905 is fixedly connected to the bottom of the fixing plate 904. A sliding groove 906 is opened on the inner side wall of the workbench 3.

[0029] The inner bottom wall of the workbench 3 is provided with a groove, which is inclined. An anti-spatter baffle 907 is fixedly connected to the inner wall of the groove. The inclined groove on the inner bottom wall of the workbench 3 can guide the debris to slide down quickly and avoid debris accumulation; the anti-spatter baffle 907 on the inner wall of the groove can block the rebound of high-temperature debris splashed during welding and reduce the probability of debris residue.

[0030] The bottom of the cleaning push plate 905 is located on the displacement trajectory of the inner bottom wall of the workbench 3. The second pulley 902 is connected to the first pulley 806 via the belt 903. The bottom of the cleaning push plate 905 covers the displacement trajectory of the inner bottom wall of the workbench 3, ensuring that there are no blind spots in debris cleaning. The second pulley 902 is connected to the first pulley 806 via the belt 903, realizing the power linkage between the welding clamping mechanism 8 and the debris cleaning device 9. No additional drive source is required, saving equipment costs and installation space.

[0031] A debris collection device 10 is provided on the side of the box 2. The debris collection device 10 includes a high-pressure air pump 1001. The side of the high-pressure air pump 1001 is fixedly connected to the side of the box 2. A collection box 1002 is fixedly connected to the bottom of the workbench 3. A nozzle 1003 is fixedly connected to the inner wall of the collection box 1002. A second collection groove 1004 is opened on the inner wall of the box 2. A collection plate 1005 is slidably connected to the side of the box 2. An observation plate 1006 is rotatably connected to the side of the box 2. An air pipe 1007 is fixedly connected to the side of the nozzle 1003.

[0032] The collecting plate 1005 is used to collect debris in the collecting box 1002 and the second collecting tank 1004. The inner wall of the collecting box 1002 is inclined. The collecting plate 1005 can collect debris in the collecting box 1002 and the second collecting tank 1004 simultaneously, reducing the number of times debris is transferred. The inclined inner wall of the collecting box 1002 accelerates the sliding of debris onto the collecting plate 1005, preventing debris from accumulating in the collecting box 1002.

[0033] The side of the nozzle 1003 is connected to the high-pressure air pump 1001 via the air pipe 1007. The direct connection between the nozzle 1003 and the high-pressure air pump 1001 via the air pipe 1007 ensures the stability and sufficient pressure of the purging airflow, improves the purging effect of residual debris, and prevents debris from affecting the quality of subsequent welding operations.

[0034] A specific application of this embodiment is as follows: the two pressure plates 810 of the welding clamping mechanism 8 are in the maximum spacing position, which facilitates the operator to place the workpiece to be welded. When it is necessary to clamp and position the workpiece, the motor 802 is started. The output shaft of the motor 802 drives the drive gear 803 to rotate. The drive gear 803 meshes with the driven gear 804, thereby driving the bidirectional screw 805 to rotate on the side wall of the worktable 3. When the bidirectional screw 805 rotates, the two connecting sleeves 807 connected by the thread on its circumferential surface are moved towards each other along the axial direction of the bidirectional screw 805 due to the action of the thread rotation direction. The connecting sleeves 807 synchronously drive the top protective sleeve 808, spring 809 and pressure plate 810 to move synchronously. When the flexible bonding block 811 on the side of the pressure plate 810 contacts the workpiece surface, then... The bidirectional screw 805 continues to rotate, and the connecting sleeve 807 further pushes the protective sleeve 808 to move. At this time, the spring 809 on the inner wall of the protective sleeve 808 undergoes elastic deformation under the pressure of the pressure plate 810, generating a reverse buffer clamping force. This buffering force is transmitted to the flexible bonding block 811 through the pressure plate 810, which can not only ensure that the workpiece is firmly clamped and avoid displacement during welding, but also avoid hard contact that could cause scratches or deformation on the workpiece surface. It is suitable for clamping workpieces of different sizes and materials. After the welding operation is completed, the motor 802 rotates in the opposite direction, driving the drive gear 803, driven gear 804 and bidirectional screw 805 to rotate in the opposite direction. The two connecting sleeves 807 drive the pressure plate 810 to move in opposite directions, releasing the clamping of the workpiece, and the operator can then take out the welded workpiece.

[0035] The debris cleaning device 9 and the welding clamping mechanism 8 are linked by a power linkage structure. When the equipment is in standby mode, the cleaning push plate 905 is in the initial position inside the worktable 3. When the welding clamping mechanism 8 is started, the motor 802 drives the bidirectional screw 805 to rotate, and at the same time, the first pulley 806 on the circumference of the bidirectional screw 805 rotates synchronously. The first pulley 806 drives the second pulley 902 to rotate through the belt 903, which in turn drives the reciprocating screw 901 to rotate on the inner wall of the worktable 3. When the reciprocating screw 901 rotates, the fixed plate 904 connected by its circumferential thread is subjected to the action of the reciprocating thread and makes a reciprocating linear motion along the axis of the reciprocating screw 901. The fixed plate 904 synchronously drives the cleaning push plate 905 at the bottom to move. During the welding operation, high-temperature metal debris is generated. The debris will fall onto the inner bottom wall of the workbench 3. At this time, the cleaning push plate 905 cleans and pushes the debris on the inner bottom wall of the workbench 3 during its reciprocating movement. The bottom of the cleaning push plate 905 is in contact with the inner bottom wall of the workbench 3, and its displacement trajectory covers the entire bottom wall area, which can ensure cleaning without dead corners. The sliding groove 906 on the inner wall of the workbench 3 limits and guides the end of the cleaning push plate 905 to ensure the stability of the movement trajectory of the cleaning push plate 905 and avoid jamming or deviation. The debris pushed by the cleaning push plate 905 will be guided to the inclined trough on the inner bottom wall of the workbench 3. The anti-splash baffle 907 on the inner wall of the trough can prevent the debris splashed during the welding process from rebounding back to the working area of ​​the workbench 3, and at the same time, it helps to guide the debris to slide down the trough and enter the subsequent debris collection device 10.

[0036] During the welding operation, on the one hand, the debris sliding down from the inclined groove on the inner bottom wall of the workbench 3 will fall directly into the collection box 1002 under the action of gravity. On the other hand, the cleaning push plate 905 of the debris cleaning device 9 will continuously push the debris inside the workbench 3 into the second collection tank 1004 during its reciprocating movement, preventing debris from the two sources from mixing and accumulating inside the equipment or from being scattered randomly. After the welding operation is completed, if it is necessary to clean the residual debris attached to the collection box 1002, the high-pressure air pump 1001 can be started: the high-pressure airflow generated by the high-pressure air pump 1001 is delivered to the nozzle 1003 through the air pipe 1007. The nozzle 1003 directs the high-pressure airflow towards the inner wall of the collection box 1002, so that the attached debris is cleaned up. The residual debris detaches from the wall and slides down onto the collection plate 1005 below under the combined action of gravity and airflow. The debris in the second collection tank 1004 will slide directly onto the collection plate 1005 by its own gravity without additional blowing. The operator can check the amount of debris accumulated on the collection plate 1005 in real time through the observation plate 1006 on the side of the box 2. When the debris accumulates to the preset amount, there is no need to disassemble other parts of the equipment. The plug-in collection plate 1005 can be directly pulled out to complete the centralized cleaning of debris. After cleaning, the collection plate 1005 is re-inserted into its original position, the observation plate 1006 is turned off, and the debris collection device 10 returns to the initial standby state, ready to wait for the next round of welding debris collection.
