Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser welding technology, and more specifically, to a laser welding clamping device. Background Technology
[0002] Laser welding is a new type of welding method with more concentrated and efficient energy. It has advantages such as fast welding speed, narrow heat-affected zone, high production efficiency and good welding quality, and is widely used in modern machining processes.
[0003] When welding workpieces, the two parts are first placed on the worktable and brought into contact with each other. Then, two electric telescopic rods are activated to press the two clamping plates against the two parts of the workpieces to fix their positions. The welding head is then activated to weld and fix the contact surfaces of the workpieces. However, in actual use, it was found that a certain gap is generated when the two workpieces are brought into contact. Moreover, the clamping plates only limit the upper position of the workpieces, and the limiting effect is weak, which leads to an increase in the gap, affecting subsequent welding, reducing the effectiveness of the clamping device and the quality of the finished workpiece. Utility Model Content
[0004] The main purpose of this utility model is to provide a laser welding clamping device.
[0005] According to a first aspect of the present invention, a laser welding clamping device is provided, including a worktable, two electric telescopic rods are fixedly connected to the surface of the worktable, and clamping plates are fixedly connected to the output ends of the two electric telescopic rods respectively. A reinforcing device is provided on the surface of the clamping plate, and the reinforcing device further limits and fixes the position of the workpiece.
[0006] When performing laser welding on a workpiece, first place the two parts of the workpiece on the worktable and make the welding points contact each other. Then, activate the two electric telescopic rods so that the two clamping plates contact and press the two parts of the workpiece respectively. Then, activate the reinforcement device to further limit and fix the workpiece. Finally, use a laser to weld and fix the contact points.
[0007] According to the laser welding clamping device of the first aspect of the present invention, the reinforcing device includes two mounting blocks, which are respectively fixedly connected to clamping plates on two electric telescopic rods. A screw is rotatably connected to each other through the two mounting blocks, with oppositely oriented threaded connections at both ends. A reinforcing column is threaded onto the arc surfaces at both ends of the screw. A limit rod is fixedly connected to the surface of both mounting blocks, and the limit rod is slidably connected to the surface of the reinforcing column. A servo motor is fixedly connected to the surface of the clamping plate, and a second gear is fixedly connected to the output end of the servo motor. A first gear is fixedly connected to the arc surface of the screw, and the first gear meshes with the second gear.
[0008] When the clamping device limits the position of the workpiece being laser welded, it can better ensure that the position of the workpiece is fixed, making it less likely to shake or produce gaps, thereby further improving the quality of the welded product and also improving the use effect and functionality of the clamping device.
[0009] According to the laser welding clamping device of the first aspect of this utility model, a reinforcing sleeve, which is a rubber sleeve, is fixedly connected to the arc surface of the reinforcing column. The reinforcing sleeve increases friction when the reinforcing column contacts and presses against the workpiece, thereby making the workpiece more stable and further improving the effectiveness of the reinforcing device.
[0010] According to the laser welding clamping device of the first aspect of this utility model, a stabilizing plate is rotatably connected through the arc surface of the screw, and the stabilizing plate is rotatably connected through the output end of the servo motor.

The outer ring of the bearing is fixedly connected to the inner wall of the mounting block, and the inner ring of the bearing is fixedly connected to the arc surface of the screw. The bearing arrangement makes the rotation of the screw on the mounting block smoother and more stable, reduces rotational wear between the screw and the mounting block, and thus better limits the positioning of the workpiece.
[0012] According to the laser welding clamping device of the first aspect of this utility model, a protective device is provided on the surface of the clamping plate. The protective device includes a protective cover, a clamping plate is fixedly connected to one side surface of the protective cover, an assembly plate is clamped to the inner wall of the clamping plate, the assembly plate is fixedly connected to the surface of the clamping plate, and a bolt is inserted through the surface of the clamping plate, the bolt being threadedly connected to the surface of the assembly plate. During use, the servo motor and surrounding components are less likely to be contacted or collided with, thus ensuring the normal operation of the clamping device and better limiting welding of the workpiece.
[0013] According to the laser welding clamping device described in the first aspect of this utility model, an operating block is fixedly connected to the surface of the bolt, and the surface of the operating block is provided with a plurality of anti-slip protrusions.

[0027] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.
[0028] Reference Figures 1 to 4As shown, a laser welding clamping device is provided, including a worktable 1. Two electric telescopic rods 2 are fixedly connected to the surface of the worktable 1. A clamping plate 3 is fixedly connected to the output end of the two electric telescopic rods 2 respectively. A reinforcing device 4 is provided on the surface of the clamping plate 3. The reinforcing device 4 further limits and fixes the position of the workpiece. When laser welding is performed on the workpiece, the two parts of the workpiece are first placed on the worktable 1 and the welding points are brought into contact with each other. Then, the two electric telescopic rods 2 are activated so that the two clamping plates 3 contact and press the two parts of the workpiece respectively. Then, the reinforcing device 4 is activated to further limit and fix the workpiece. Then, the laser is used to weld and fix the contact position.
[0029] Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the reinforcing device 4 includes two mounting blocks 41, which are fixedly connected to the clamping plates 3 on the two electric telescopic rods 2 respectively. The two mounting blocks 41 are rotatably connected to each other through screws 42. The two ends of the screws 42 are respectively provided with threaded connections in opposite directions. The two ends of the screws 42 are respectively threaded to the arc surfaces of the two ends of the screws 42. The surfaces of the two mounting blocks 41 are fixedly connected to a limit rod 44. The limit rod 44 is slidably connected to the surface of the reinforcing rod 43. The surface of the clamping plate 3 is fixedly connected to a servo motor 45. The output end of the servo motor 45 is fixedly connected to a second gear 47. The arc surface of the screws 42 is fixedly connected to a first gear 46, which meshes with the second gear 47.
[0030] When performing laser welding on a workpiece, the two parts of the workpiece are first placed on the worktable 1 and brought into contact with each other at the welding point. Then, the two electric telescopic rods 2 are activated, causing the two clamping plates 3 to press against the two parts of the workpiece respectively. Then, the servo motor 45 on the clamping plate 3 causes the second gear 47 on the output end of the servo motor 45 to rotate. Because the first gear 46 and the second gear 47 on the screw 42 mesh with each other, the screw 42 will rotate on the mounting block 41. Due to the sliding limiting effect of the reinforcing column 43 and the limiting rod 44, the reinforcing columns 43 at both ends will move closer to each other when the screw 42 rotates, until the two reinforcing columns 43 contact and press against the two parts of the workpiece respectively, making the contact position of the two workpieces more closely fit. At this time, when the clamping device limits the laser-welded workpiece, it can better ensure the fixed position of the workpiece, making it less prone to shaking or gaps, thereby further improving the quality of the welded product and improving the use effect and functionality of the clamping device.
[0031] Figure 1 , Figure 2 and Figure 3As shown, in some embodiments of this utility model, a reinforcing sleeve 48 is fixedly connected to the arc surface of the reinforcing column 43. The reinforcing sleeve 48 is a rubber sleeve. By setting the reinforcing sleeve 48, the friction of the reinforcing column 43 when it contacts and squeezes the workpiece is further increased, thereby making the position of the workpiece more stable and further improving the performance of the reinforcing device 4.
[0032] Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of this utility model, a stabilizing plate 49 is rotatably connected through the arc surface of the screw 42. The stabilizing plate 49 is rotatably connected through the output end of the servo motor 45. By setting the stabilizing plate 49, the meshing of the first gear 46 and the second gear 47 is more stable and less prone to misalignment and jamming, thereby ensuring the normal operation of the screw 42.
[0033] Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments of this utility model, bearings 410 are fixedly connected to the inner walls of the two mounting blocks 41 respectively. The outer ring of the bearing 410 is fixedly connected to the inner wall of the mounting block 41, and the inner ring of the bearing 410 is fixedly connected to the arc surface of the screw 42. By setting the bearings 410, the rotation of the screw 42 on the mounting block 41 is smoother and more stable, and the screw 42 and the mounting block 41 are less prone to rotational wear, thereby better limiting the workpiece.
[0034] Figure 1 and Figure 4 As shown, in some embodiments of this utility model, the protective device 5 includes a protective cover 51. A clamping plate 52 is fixedly connected to one side surface of the protective cover 51. An assembly plate 53 is clamped to the inner wall of the clamping plate 52. The assembly plate 53 is fixedly connected to the surface of the pressure plate 3. A bolt 54 is inserted through the surface of the clamping plate 52. The bolt 54 is threadedly connected to the surface of the assembly plate 53. When the reinforcement device 4 is assembled and used, the protective cover 51 covers the surface of the servo motor 45 and simultaneously covers the surfaces of the first gear 46 and the second gear 47. The clamping plate 52 fixedly connected to the protective cover 51 is clamped to the assembly plate 53 fixedly connected to the surface of the pressure plate 3. Then, the bolt 54 passes through the surface of the clamping plate 52 until the bolt 54 is threadedly connected to the surface of the assembly plate 53, so that the position of the protective cover 51 is stable. At this time, when the reinforcement device 4 is in use, the servo motor 45 and the surrounding device components are not easily contacted or collided, thereby ensuring the normal use of the reinforcement device 4 and better limiting welding of the workpiece.
[0035] Figure 1 and Figure 4As shown, in some embodiments of this utility model, an operating block 55 is fixedly connected to the surface of the bolt 54. The surface of the operating block 55 is provided with several anti-slip protrusions. The operation block 55 makes it easier for the bolt 54 to rotate during use and makes it easier to disassemble and assemble the protective cover 51, thus improving the ease of use of the protective device 5. A washer 56 is fitted on the arc surface of the bolt 54. The washer 56 abuts against the surface of the mounting plate 53. The washer 56 makes the bolt 54 fit more securely and stably on the clamping plate 52, and it is not easy to rotate or loosen, thereby ensuring the stable assembly of the protective cover 51.
[0036] When performing laser welding on a workpiece, the two parts of the workpiece are first placed on the worktable 1 and brought into contact with each other at the welding point. Then, the two electric telescopic rods 2 are activated, causing the two clamping plates 3 to press against the two parts of the workpiece respectively. Then, the servo motor 45 on the clamping plate 3 causes the second gear 47 on the output end of the servo motor 45 to rotate. Because the first gear 46 and the second gear 47 on the screw 42 mesh with each other, the screw 42 will rotate on the mounting block 41. Due to the sliding limiting effect of the reinforcing column 43 and the limiting rod 44, the reinforcing columns 43 at both ends will move closer to each other when the screw 42 rotates, until the two reinforcing columns 43 contact and press against the two parts of the workpiece respectively, making the contact position of the two workpieces more closely fit. At this time, when the clamping device limits the laser-welded workpiece, it can better ensure the fixed position of the workpiece, making it less prone to shaking or gaps, thereby further improving the quality of the welded product and improving the use effect and functionality of the clamping device.
[0037] When the reinforcement device 4 is assembled and used, the protective cover 51 covers the surface of the servo motor 45 and the surfaces of the first gear 46 and the second gear 47. The clamping plate 52 fixedly connected to the protective cover 51 is clamped onto the assembly plate 53 fixedly connected to the surface of the clamping plate 3. Then, the bolt 54 is passed through the surface of the clamping plate 52 until the bolt 54 is threadedly connected to the surface of the assembly plate 53, so that the position of the protective cover 51 is stable. At this time, when the reinforcement device 4 is used, the servo motor 45 and the surrounding device components are not easily contacted or collided, thereby ensuring the normal use of the reinforcement device 4 and better limiting welding of the workpiece.
