Abstract
Description
Technical Field
[0001] This utility model belongs to the field of laser welding cooling technology, specifically a laser welding cooling device. Background Technology
[0002] Laser welding machines, also known as laser welding machines or laser welding machines, are machines used for laser material processing. Their working principle is to use high-energy laser pulses to locally heat a small area of the material. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool.
[0003] The specific design and structure of the drawing structure for carbon steel submerged arc welding wire may vary depending on different manufacturers and application requirements, but generally they include the following key components: cooling pumps and filters, etc. The cooling pump is the power source that drives the cooling medium to circulate in the system. It usually uses a corrosion-resistant, high-head centrifugal pump or magnetic pump to ensure that the cooling medium flows in the cooling channel with a stable flow rate and pressure, achieving efficient heat dissipation. The filter is installed in the cooling medium circulation system to filter impurities and particles in the cooling medium, preventing them from entering the cooling channel and critical components, causing blockage or wear. The filter usually uses a high-precision filter screen or filter element, which needs to be cleaned or replaced regularly.
[0004] Currently, existing laser welding cooling devices do not allow for the recycling of coolant during use; instead, the coolant is used only once, resulting in significant waste and increased operating costs. During the laser welding cooling process, various impurities and waste materials, such as metal shavings and welding slag, are mixed into the coolant. These impurities accumulate in the coolant, making it difficult to recycle. Utility Model Content
[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a laser welding cooling device.
[0006] The technical solution adopted by this utility model to solve its technical problem is a laser welding cooling device, including a box body. An arc-shaped filter plate is installed inside the box body. A first motor bracket is installed on the side of the box body, and a pusher motor is installed on the first motor bracket. An auger shaft is rotatably installed inside the box body, and auger blades are installed on the auger shaft. The output end of the pusher motor is fixedly connected to the auger shaft. A discharge port is installed at the top of the auger shaft, and a waste bin is installed on the side of the discharge port. A trapezoidal guide block is installed below the arc-shaped filter plate, and a coolant tank is installed at the bottom of the trapezoidal guide block. A transmission rail is installed on the side of the box body, and a transmission screw is rotatably installed inside the transmission rail. A second motor is installed on the side of the transmission rail. The machine frame includes a drive motor mounted on the second motor bracket, a drive support slidably disposed within the drive rail, a threaded hole on the drive support, through which the drive screw rotates, an adjusting block on the drive support, a drive groove within the adjusting block, an adjusting screw rotatably disposed within the drive groove, a third motor bracket on the side of the adjusting block, an adjusting motor mounted on the third motor bracket, the output end of the adjusting motor being fixedly connected to the adjusting screw, a sliding block slidably disposed within the drive groove, a welding cylinder at the bottom of the sliding block, a welding plate at the output end of the welding cylinder, and a laser welding gun at the bottom of the welding plate.
[0007] Preferably, the laser welding gun has a liquid collection chamber on its side, and a plurality of cooling water guns are provided on the liquid collection chamber. The liquid collection chamber and cooling water guns allow the coolant to be sprayed directly onto the laser welding gun, quickly removing the heat generated during the welding process, effectively reducing the temperature of the laser welding gun, preventing it from being damaged due to overheating, extending the service life of the laser welding gun, and ensuring the stability of the welding quality.
[0008] Preferably, the housing is provided with a worktable, and a fixing cylinder is provided at each end of the worktable. A fixing plate is provided at the output end of the fixing cylinder. The fixing cylinder and fixing plate at both ends of the worktable can adjust the position of the fixing plate according to the size of the workpiece, so as to firmly fix the workpiece on the worktable. Stable workpiece fixing helps to ensure the positional accuracy of the workpiece during the welding process, avoids welding deviation caused by workpiece movement, and improves welding quality and consistency.
[0009] Preferably, the transmission bracket is provided with a mounting plate, and the mounting plate is provided with a cooling water pump. The cooling water pump is provided with a liquid extraction pipe and a cooling pipe. The other end of the liquid extraction pipe is connected to the coolant tank, and the other end of the cooling pipe is provided on the liquid collection tank. The cooling water pump draws coolant from the coolant tank through the liquid extraction pipe and then delivers it to the liquid collection tank through the cooling pipe, forming a complete coolant circulation system. This circulation supply method ensures the continuous supply and effective utilization of coolant, improves cooling efficiency, and reduces operating costs.
[0010] Preferably, the coolant tank is equipped with a delivery pipe and a drain valve. The coolant tank serves as a storage container for coolant, and the delivery pipe facilitates the replenishment of coolant. The drain valve allows for the replacement of coolant or equipment maintenance when needed. The cooling water pump circulates the coolant in the system, continuously providing cooling for the laser welding gun, forming a complete cooling cycle system, which improves the utilization rate of coolant and reduces operating costs.
[0011] Preferably, the pusher motor, drive motor, regulating motor, welding cylinder, laser welding gun, stationary cylinder, and cooling water pump are all connected to an external controller. The controller is used to start and stop the pusher motor, drive motor, regulating motor, welding cylinder, laser welding gun, stationary cylinder, and cooling water pump. This centralized automated control method makes the operation of the entire laser welding cooling device more convenient and efficient. Operators only need to set the corresponding parameters and programs on the controller, and the equipment can automatically complete the welding and cooling process, reducing manual intervention, improving production efficiency, and also reducing the impact of human factors on welding quality.
[0012] The advantages of this invention are as follows: the arc-shaped filter plate inside the housing can filter the coolant, intercepting impurities and waste. The pusher motor drives the auger shaft and auger blades to rotate, which can transport the filtered waste to the discharge port and discharge it into the waste bin. This automatic waste cleaning method avoids the accumulation of impurities in the coolant, ensures the cleanliness of the coolant, and thus improves the cooling effect. It also reduces the risk of impurities clogging the cooling pipes or damaging equipment such as the cooling water pump. The cooling water pump makes the coolant circulate in the system, continuously providing cooling for the laser welding gun, forming a complete cooling cycle system, improving the utilization rate of the coolant and reducing operating costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0021] Please see Figure 1-5 As shown, a laser welding cooling device includes a housing 1, an arc-shaped filter plate 20 inside the housing 1, a first motor bracket 21 on the side of the housing 1, a pusher motor 22 on the first motor bracket 21, an auger shaft 23 rotatably mounted inside the housing 1, an auger blade 24 mounted on the auger shaft 23, the output end of the pusher motor 22 being fixedly connected to the auger shaft 23, a discharge port at the top of the auger shaft 23, a waste bin 35 on the side of the discharge port, a trapezoidal guide block 25 below the arc-shaped filter plate 20, and a coolant tank 26 at the bottom of the trapezoidal guide block 25.
[0022] During operation, in order to filter the coolant mixture after welding, when the coolant flows into the tank 1, it first passes through the arc-shaped filter plate 20. The arc-shaped filter plate 20 intercepts impurities and waste in the coolant, playing a preliminary role in purifying the coolant. At this time, the pusher motor 22 starts, which drives the auger shaft 23 connected to it to rotate. Since the auger shaft 23 is equipped with auger blades 24, as the auger shaft 23 rotates, the auger blades 24 push the waste intercepted by the arc-shaped filter plate 20 to move upward along the auger shaft 23 until it reaches the discharge port at the top of the auger shaft 23. Finally, the waste is discharged into the waste box 35 on the side of the discharge port. The filtered coolant then flows through the arc-shaped filter plate 20 and is guided by the trapezoidal guide block 25 into the coolant tank 26 at its bottom for storage.

[0024] During operation, in order to weld the workpiece, before the welding operation, the workpiece is placed on the worktable 32 on the housing 1. The fixed cylinders 33 at both ends of the worktable 32 are activated, pushing the fixed plate 34 at its output end to move towards the workpiece until the workpiece is firmly fixed on the worktable 32. The transmission motor 31 is activated, driving the transmission screw 4 in the transmission rail 2 to rotate. The rotation of the transmission screw 4 is converted into the linear motion of the transmission bracket 5 in the transmission rail 2, thereby realizing the horizontal position adjustment of the laser welding gun 19. The adjustment motor 10 is activated, driving the adjustment screw 13 in the transmission slide groove 12 in the adjustment block 11 to rotate. The sliding block 14 slides in the transmission slide groove 12 and cooperates with the adjustment screw 13. The rotation of the adjustment screw 13 causes the sliding block 14 to move left and right in the transmission slide groove 12. At the same time, the welding cylinder 15 is activated, driving the laser welding gun 19 to move downward to the appropriate position through the welding plate 16. Then the welding gun is activated to weld the workpiece.

The housing 1 is provided with a workbench 32, and a fixed cylinder 33 is provided at each end of the workbench 32. A fixed plate 34 is provided at the output end of the fixed cylinder 33.
[0026] The transmission bracket 5 is provided with a mounting plate 6, the mounting plate 6 is provided with a cooling water pump 7, the cooling water pump 7 is provided with a liquid extraction pipe and a cooling pipe 8, the other end of the liquid extraction pipe is connected to the coolant tank 26, the other end of the cooling pipe 8 is provided on the liquid collection chamber 17, and the coolant tank 26 is provided with a liquid delivery pipe 29 and a liquid drain valve 28.
[0027] The pusher motor 22, drive motor 31, regulating motor 10, welding cylinder 15, laser welding gun 19, fixed cylinder 33 and cooling water pump 7 are all connected to an external controller. The controller is used to control the start and stop of the pusher motor 22, drive motor 31, regulating motor 10, welding cylinder 15, laser welding gun 19, fixed cylinder 33 and cooling water pump 7.
[0028] During operation, in order to cool the workpiece during laser welding, the cooling water pump 7 is started. The cooling water pump 7 draws coolant from the coolant tank 26 through the extraction pipe, and then delivers the coolant to the collection chamber 17 on the side of the laser welding gun 19 through the cooling pipe 8. Several cooling water guns 18 are installed on the collection chamber 17. The coolant is sprayed out from the cooling water guns 18 to directly cool the laser welding gun 19 and the workpiece being welded, remove the heat generated by welding, and ensure the normal operating temperature of the laser welding gun 19 and the quality of the workpiece welding interface.
[0029] Working principle: In order to weld the workpiece, before the welding operation, the workpiece is placed on the worktable 32 on the housing 1. The fixed cylinders 33 at both ends of the worktable 32 are activated, pushing the fixed plate 34 at its output end to move towards the workpiece until the workpiece is firmly fixed on the worktable 32. The transmission motor 31 is activated, driving the transmission screw 4 in the transmission rail 2 to rotate. The rotation of the transmission screw 4 is converted into the linear motion of the transmission bracket 5 in the transmission rail 2, thereby realizing the horizontal position adjustment of the laser welding gun 19. The adjustment motor 10 is activated, driving the adjustment screw 13 in the transmission slide groove 12 in the adjustment block 11 to rotate. The sliding block 14 slides in the transmission slide groove 12 and cooperates with the adjustment screw 13. The rotation of the adjustment screw 13 causes the sliding block 14 to move left and right in the transmission slide groove 12. At the same time, the welding cylinder 15 is activated, driving the laser welding gun 19 to move downward to the appropriate position through the welding plate 16. Then the welding gun is activated to weld the workpiece.
[0030] To cool the workpiece during laser welding, the cooling water pump 7 is started. The cooling water pump 7 draws coolant from the coolant tank 26 through the extraction pipe, and then delivers the coolant to the collection chamber 17 on the side of the laser welding gun 19 through the cooling pipe 8. Several cooling water guns 18 are installed on the collection chamber 17. The coolant is sprayed out from the cooling water guns 18 to directly cool the laser welding gun 19 and the workpiece being welded, remove the heat generated by welding, and ensure the normal operating temperature of the laser welding gun 19 and the quality of the welded joint of the workpiece.
[0031] To filter the coolant mixture after welding, the coolant first passes through the arc-shaped filter plate 20 after flowing into the tank 1. The arc-shaped filter plate 20 intercepts impurities and waste in the coolant, thus purifying it initially. At this time, the pusher motor 22 starts, which drives the auger shaft 23 connected to it to rotate. Since the auger shaft 23 is equipped with auger blades 24, as the auger shaft 23 rotates, the auger blades 24 push the waste intercepted by the arc-shaped filter plate 20 upward along the auger shaft 23 until it reaches the discharge port at the top of the auger shaft 23. Finally, the waste is discharged into the waste box 35 on the side of the discharge port. The filtered coolant then flows through the arc-shaped filter plate 20 and is guided by the trapezoidal guide block 25 into the coolant tank 26 at its bottom for storage.
