Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, and in particular to a multi-station laser welding workbench. Background Technology

[0002] Laser welding is a precision welding technology that uses a high-energy-density laser beam as a heat source to locally heat materials, melt them, and achieve a connection. It features high precision, a small heat-affected zone, and fast welding speed.

[0003] When a laser beam irradiates the surface of a metal material, the local high temperature can cause the material to melt or even vaporize. As the metal vapor escapes, it cools and condenses into tiny metal oxide particles, forming "metal fumes". Long-term exposure to such fumes may cause harm to the operator's respiratory system, skin, etc.

[0004] Currently, due to the large number of welding points on multi-station workbenches, a significant amount of fumes are typically generated. Traditional workbenches struggle to efficiently and quickly absorb and process the fumes from each station. Therefore, the inventors have proposed an improved multi-station laser welding workbench.

[0038] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0039] This utility model embodiment specifically provides a multi-station laser welding worktable; please refer to... Figures 1-5 It includes a platform 1, a fumigation pipe 2 and an air extraction channel 3. A clamping table 11 is fixed on the surface of the platform 1, and an air filter 12 is provided on the platform 1. The workpiece is clamped and welded through the clamping table 11. The air filter 12 is a common air handling equipment. It is equipped with an exhaust fan and a filter membrane assembly inside, which can filter the extracted gas before it is discharged.

[0040] The smoke extraction pipe 2 is connected to the air extraction end of the air filter 12 through the air extraction channel 3. The bottom of the air extraction pipe 3 is placed on the placement surface, and the air extraction pipe 3 is fixedly connected to the outside of the air filter 12, so that the gas inside the air extraction pipe 3 can be introduced into the air extraction end of the air filter 12, thereby filtering the smoke delivered from the air extraction pipe 3.

[0041] Specifically, the fumigation fitting 2 includes an L-shaped tube 21, a corrugated hose 22, and an adjusting tube 23. The upper and lower ends of the L-shaped tube 21 are fixedly connected to the adjusting tube 23 and the air extraction channel 3 through the corrugated hose 22, respectively, so that after the smoke is drawn in through the adjusting tube 23, it can be sent into the air extraction channel 3 along the L-shaped tube 21. According to the characteristics of the corrugated hose 22, it can be extended and adjusted for easy subsequent adjustment. The air extraction direction of the adjusting tube 23 is close to the fixture table 11. A positioning component 24 is provided between the adjusting tube 23 and the L-shaped tube 21 to adjust the distance between the adjusting tube 23 and the fixture table 11, so as to facilitate the adaptation when welding workpieces of different sizes. The lower outer side of the L-shaped tube 21 is connected to the height adjustment component 4, and the height of the L-shaped tube 21 is adjusted by the height adjustment component 4 to adapt to different welding workpieces.

[0042] Furthermore, the positioning component 24 includes a mounting frame 241 whose bottom end is fixedly connected to the L-shaped tube 21 and a positioning bracket 242 whose bottom end is fixedly connected to the adjusting tube 23. The top end of the positioning bracket 242 is detachably connected to the mounting frame 241, thereby adjusting the position of the adjusting tube 23 by connecting or separating the positioning bracket 242 from the mounting frame 241.

[0043] Specifically, the mounting frame 241 has a hollow structure inside, and the bottom of the cavity is open. Slide grooves 243 are provided on the left and right sides of the cavity. The slide grooves 243 are used to match and connect with the positioning frame 242 so that the positioning frame 24 can move linearly along the length of the mounting frame 241.

[0044] The top of the mounting frame 241 is made of iron. The top of the positioning frame 242 is fixed with magnetic plates 244 at both ends that slide in cooperation with the slide groove 243. The top of the magnetic plates 244 is magnetically connected to the positioning frame 242. When it is necessary to move the adjusting tube 23, the positioning frame 242 can be pressed down first to separate the magnetic plates 244 from the top of the mounting frame 241. Then, it can slide along the slide groove 243 to move the adjusting tube 23. After reaching the appropriate position, the positioning frame 242 is moved upward to reconnect the magnetic plates 422 with the mounting frame 241, thus fixing the positioning frame 2442 in place. This allows the smoking position of the distance between the adjusting tube 23 and the fixture table 11 to be reasonably adjusted according to the size of different workpieces and the position of the welding points.

[0045] During implementation, an exhaust fan 211 is fixedly installed inside the L-shaped pipe 21, so that the flue gas outside the regulating pipe 23 can be quickly drawn into the L-shaped pipe 21 through the exhaust fan 211. The exhaust fan 211 is preferably an electric fan.

[0046] Furthermore, the height adjustment component 4 includes a mounting plate 41 fixedly connected to the outside of the L-shaped tube 21, a guide frame 42 slidably engaged with the mounting plate 41, and a retaining component 43 connected to the guide frame 42. The end of the retaining component 43 away from the guide frame 42 is connected to the control component 44. The retaining component 43 is operated by the control component 44, so that the mounting plate 41 can drive the L-shaped tube 21 to move up and down.

[0047] The mounting plate 41 has a sliding opening 411. The guide frame 42 includes a guide frame 421 and a retaining frame 422 that are fixedly connected to the top of the platform 1. The outer sides of the guide frame 421 and the retaining frame 422 slide in contact with the sliding opening 411. By setting the guide frame 421 and the retaining frame 422, the mounting plate 41 can slide up and down stably to meet the height adjustment requirements of the L-shaped tube 21.

[0048] Specifically, the retaining frame 422 has a plurality of retaining holes 423 on the side near the retaining component 43, and the retaining holes 423 are equidistantly spaced along the height direction of the retaining frame 422.

[0049] The retaining assembly 43 includes a rod 431 with one end inserted into the retaining hole 423. The upper surface of the mounting plate 41 is fixed with a mounting sleeve 412 that is slidably connected to the rod 431, so that the rod 431 can slide stably along the mounting sleeve 412.

[0050] The insertion rod 431 is fixedly provided with a protrusion ring 432 on the outside. The outside of the protrusion ring 432 is connected to the mounting sleeve 412 through a spring 433. When the insertion rod 431 moves outward, the protrusion ring 432 can apply force to the spring 433, which can compress the spring 433 and generate elastic force, so that the insertion rod 431 can quickly return to its original position and be stably connected to the fixing hole 423.

[0051] Furthermore, the control assembly 44 includes a support frame 441 fixedly connected to the other end of the insertion rod 431 and a foot pedal 442 fixedly installed at the bottom of the support frame 441. When the worker needs to adjust the height of the L-shaped tube 21, he can operate it through the foot pedal 442.

[0052] Specifically, a force-bearing frame 443 is fixedly provided on the upper surface of the foot pedal 442. During operation, after stepping on the foot pedal 442, the foot passes through the force-bearing frame 443. Then, the ball of the foot applies an upward and backward pulling force to the force-bearing frame 443, separating the insertion rod 431 from the fixing hole 423. Then, the foot moves up and down, causing the support 441 to drive the insertion rod 431 to move up and down. Once it reaches the appropriate position, it can be inserted into the corresponding fixing hole 423.

[0053] The above describes the basic principles, main features, and advantages of this utility model. The standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, which will not be described in detail here.
