Description

Technical Field

[0001] The invention belongs to the technical field of component welding, and in particular relates to welding equipment for component processing and a use method thereof. Background Art

[0002] Laser welding is a welding method that uses the high energy density of the laser beam to instantly melt and fuse the surface of the weldment together. When the laser beam is irradiated on the surface of the weldment, the light energy is absorbed by the weldment and converted into heat energy, causing the surface temperature of the weldment to rise rapidly to the melting point or even boiling point, forming a molten pool. As the laser beam moves, the liquid metal in the molten pool cools and solidifies to form a weld.

[0003] Welding equipment is often used in parts processing. As for the vertical tangent welding of metal pipes, there are some parts in the existing welding equipment that need to be improved: 1. The welding point cannot be automatically cleaned and dusted. Impurities and dust adhering to the parts will affect the subsequent welding quality; 2. The laser welding head cannot be quickly moved away from the welding part after welding. The temperature of the area where the welding has just been completed is relatively high. If the welding head is close to the high temperature area for a long time, it may be affected by thermal radiation, causing damage to the optical elements, sensors and other components inside the welding head, affecting the service life of the welding head.

DETAILED DESCRIPTION

[0028] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0029] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 7 As shown, a welding device for parts processing provided by an embodiment of the present invention includes a processing table 1, on which a fixing mechanism 3 and an electric slide rail 4 are provided, on which a first metal tube 7 and a second metal tube 8 are fixed, and on which an electric slider 5 is slidably connected, and on which the electric slider 5 is provided a cleaning mechanism 2, the cleaning mechanism 2 includes a rack 22, a gear 23, a ball 29 and a cleaning roller 214, the rack 22 is meshingly connected with the gear 23, a laser welding head 6 is fixedly mounted on the upper surface of the gear 23, and the ball 29 and the cleaning roller 214 are both rollingly connected to the weld between the first metal tube 7 and the second metal tube 8.

[0031] Furthermore, the fixing mechanism 3 includes a motor 33 and a fixing box 34, a guide base frame 310 is fixedly connected to the middle of the upper surface of the fixing box 34, the second metal tube 8 is placed in the guide base frame 310, the fixing box 34 is fixedly installed on the upper surface of the processing table 1, the motor 33 is fixedly installed at one end of the fixing box 34, a screw rod 35 is rotatably installed inside the fixing box 34, the output end of the motor 33 is fixedly connected to one end of the screw rod 35, screw rod sleeves 36 are threadedly sleeved on the rod body at both ends of the screw rod 35, and the upper surfaces of the two screw rod sleeves 36 are respectively fixedly connected to the first The first clamping block 31 and the second clamping block 32 are provided with beveled surfaces on both sides. The upper ends of the first clamping block 31 and the second clamping block 32 are rotatably connected with screws 37, and the screws 37 are threadedly sleeved with lifting blocks 38. The two lifting blocks 38 are respectively slidably connected to the inner walls of the upper ends of the first clamping block 31 and the second clamping block 32. The lower surface of one end of the lifting block 38 extending from the first clamping block 31 and the second clamping block 32 is fixedly connected with a pressing block 39, and the two pressing blocks 39 are respectively crimped to the two ends of the first metal tube 7.

[0032] Specifically, the second metal tube 8 is placed in the guide frame 310, and the two sides of the second metal tube 8 are tangent to the two sides of the guide frame 310, and are automatically adjusted to the middle of the guide frame 310, and then the top of the first metal tube 7 is pressed against the inner walls of the two ends of the pressing block 39, and the lifting block 38 and the pressing block 39 are pressed downward by rotating the screw rods 37 at both ends, and the pressing block 39 and the first metal tube 7 move downward until the first metal tube 7 is pressed tightly against the second metal tube 8, thereby achieving the initial fixation of the first metal tube 7 and the second metal tube 8, and then the screw rod 35 is driven to rotate by the starting motor 33, and the two screw rod sleeves 36 are driven to move synchronously toward the middle through the screw rod 35, so that the first tightening block 31 and the second tightening block 32 are close to each other.

[0033] It should be noted that the screw sleeve 36 is slidably matched with the inner wall of the screw 35, the first clamping block 31 and the second clamping block 32 are symmetrically arranged on the screw 35, the screw 37, the lifting block 38 and the pressing block 39 thereon have the same structure, the two beveled surfaces are respectively located at the end away from the first clamping block 31 and the second clamping block 32, the initial position of the laser welding head 6 is located at one end of the second clamping block 32, and the welding termination position is located at one end of the first clamping block 31.

[0034] When in use, the first clamping block 31 and the second clamping block 32 are brought close to each other, and finally the two ends of the first metal tube 7 and the second metal tube 8 are clamped together, which can further fix the first metal tube 7 and the second metal tube 8 and improve the stability of the first metal tube 7 and the second metal tube 8 during welding.

[0035] Furthermore, the cleaning mechanism 2 also includes a mounting frame 21, which is fixedly mounted on the upper surface of the electric slider 5, a rack 22 is slidably connected to the upper end of the mounting frame 21, a gear 23 is rotatably mounted on the upper end of the mounting frame 21, a connecting block 25 is fixedly connected to one side of the rack 22, a limiting rod 26 and a spring 27 are fixedly mounted on one side of the upper end of the mounting frame 21, the spring 27 is sleeved on the rod body of the limiting rod 26, the connecting block 25 is slidably sleeved on the limiting rod 26, and one end of the spring 27 is fixedly connected to the connecting block 25.

[0036] Furthermore, a support frame 24 is detachably mounted on one end of the upper surface of the rack 22, a fixing frame 28 is fixedly connected to one side of the end of the support frame 24, a ball 29 is rotatably connected to the inside of one end of the fixing frame 28, a rotating roller 210 is rotatably connected to the end of the support frame 24, the rotating roller 210 abuts against the ball 29, a first I-shaped shaft 211 is fixedly sleeved in the middle of the rotating roller 210, a connecting frame 215 is fixedly connected to the side of the end of the support frame 24 away from the fixing frame 28, a cleaning roller 214 is rotatably mounted on one end of the connecting frame 215 away from the support frame 24, a second I-shaped shaft 212 is fixedly sleeved in the middle of the cleaning roller 214, and a transmission belt 213 is sleeved on the second I-shaped shaft 212 and the first I-shaped shaft 211.

[0037] Specifically, the rack 22 is slidably connected to the inside of the upper end of the mounting frame 21, and the gear 23 and the connecting block 25 are respectively located on both sides of the rack 22. By moving the rack 22 inward or outward, the gear 23 can be driven to rotate, thereby driving the laser welding head 6 to rotate. The spring 27 is set to connect with the connecting block 25. When one end of the support frame 24 is pressed to drive the rack 22 to move outward, the connecting block 25 moves accordingly, causing the spring 27 to stretch. When the pressure at one end of the support frame 24 is eliminated, the spring 27 rebounds, driving the rack 22 to reset.

[0038] It should be noted that the mounting position of the support frame 24 on the rack 22 is adjustable, and can be adjusted accordingly according to the weld distance of parts of different specifications, ensuring that one end of the laser welding head 6 rotates to the best welding point when the ball 29 abuts against the weld, thereby improving the scope of application.

[0039] In the initial state, the ball 29 is located on the side of the second abutting block 32 away from the first abutting block 31. When the first metal tube 7 and the second metal tube 8 are fixed, the ball 29 is driven to move by the electric slider 5. The ball 29 moves along the inclined surface of the second abutting block 32, and the support frame 24 and the rack 22 are driven to move outward under pressure, so that the gear 23 drives the laser welding head 6 to rotate in the direction close to the second abutting block 32. When the ball 29 moves to the weld, the rack 22 no longer moves outward, and the gear 23 no longer drives the laser welding head 6 to rotate. When the welding end of the laser welding head 6 is located at one end of the weld, the welding work starts. As the electric slider 5 continues to move, the ball 29 rolls along the weld, and the rotating roller 210 rotates synchronously when the ball 29 rotates by abutting against the ball 29. The cleaning roller 214 is driven to rotate synchronously by the first I-shaft 211, the second I-shaft 212 and the transmission belt 213, so as to clean the weld, avoid the influence of dust or impurities at the weld on the welding, and improve the welding quality.

[0040] When the ball 29 and the cleaning roller 214 move to the first clamping block 31, the laser welding head 6 is close to the tail end of the weld. When the cleaning roller 214 slides out from the beveled surface of the first clamping block 31, the laser welding head 6 completes welding, and the rack 22 is driven inward by the spring 27, so that the gear 23 drives the laser welding head 6 to rotate outward, so that the laser welding head 6 is away from the welding point, avoiding damage to the optical elements, sensors and other components at the end of the laser welding head 6 due to the influence of thermal radiation, thereby extending the service life of the laser welding head 6 and avoiding accidental touch and burns when personnel are unloading.

[0041] like Figure 1-Figure 7 As shown, a method for using a welding device for parts processing provided by an embodiment of the present invention comprises the following steps:

[0042] S1: Fix the second metal tube 8 and the first metal tube 7 by the fixing mechanism 3, so that the first metal tube 7 is located above the second metal tube 8 and the two are tangent to each other;

[0043] S2: Start the electric slide 5 to move along the electric slide rail 4, drive the cleaning mechanism 2 and the laser welding head 6 to move, so that the cleaning mechanism 2 moves from one end of the fixing mechanism 3 to the welding seam between the first metal tube 7 and the second metal tube 8. During this process, the cleaning mechanism 2 drives the laser welding head 6 to rotate, so that the welding end of the laser welding head 6 gradually rotates to the welding seam;

[0044] S3: The ball 29 and the cleaning roller 214 roll along the weld, and the cleaning roller 214 cleans the dust and debris at the weld to ensure the welding quality;

[0045] S4: When the ball 29 and the cleaning roller 214 move to one end of the fixing mechanism 3, the laser welding head 6 is close to the welding tail end. After the cleaning roller 214 is separated from the fixing mechanism 3, the rack 22 drives the laser welding head 6 to rotate in the direction away from the weld, so that the welding is automatically moved away, reducing the thermal damage of the laser welding head 6.

[0046] To sum up: this kind of welding equipment for parts processing can firmly fix the first metal tube 7 and the second metal tube 8 through the fixing mechanism 3, thereby improving the stability and reliability of the equipment for welding processing of tubular parts, and driving the cleaning mechanism 2 and the laser welding head 6 to perform mobile cleaning and welding through the electric slider 5, which can effectively remove dust and impurities at the welding site to ensure the welding quality, and can also make the laser welding head 6 automatically move away from the welding site at the end of welding, thereby avoiding damage to the optical elements, sensors and other components at the end of the laser welding head 6 due to the influence of thermal radiation, thereby extending the service life of the laser welding head 6, and avoiding accidental touch and burns when personnel are unloading.
