Technical Field
[0001] This utility model relates to the field of water pump manufacturing and processing technology, specifically a water pump manufacturing welding device. Background Technology
[0002] A water pump is a machine that can be used to transport or pressurize liquids. During the manufacturing process of a water pump, it needs to be welded using a welding device.
[0003] Welding equipment generally consists of a workbench, welding torch, cylinder, and moving assembly. The water pump is placed on the workbench, the cylinder is started to adjust the height of the welding torch, and the moving assembly drives the welding torch to move, welding the water pump during the movement.
[0004] However, welding torches produce strong light during use, which can irritate the eyes of workers and cause damage. Workers need to wear protective masks for protection, which is inconvenient and affects welding efficiency. Therefore, a water pump production welding device is proposed to address the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, and considering the problem that welding torches produce strong light that can irritate workers' eyes and cause damage, requiring workers to wear protective masks for protection, which is inconvenient and affects welding efficiency, this utility model proposes a water pump production welding device.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A water pump production welding device of this utility model includes a workbench and a welding torch; support legs are installed around the bottom side of the workbench, the welding torch is installed on the bottom side of the slider, a protective component is installed on one side of the slider, a fixing component is provided on the top side of the workbench, a first cylinder is fixed on the top side of the workbench, a first piston rod is installed on the working end of the first cylinder, a first connecting plate is fixed on the top side of the first piston rod, and a moving component is provided on the bottom side of the first connecting plate;
[0007] The protective assembly includes a slider, a second connecting plate fixed to one side of the slider, a mounting bracket fixed to the bottom side of the second connecting plate, and sleeves fixed to both sides of the mounting bracket. A groove is formed on one side of each sleeve. A first rotating rod is mounted inside one of the sleeves via a bearing. A light-shielding film is rotatably fitted onto the outer side of the first rotating rod. The other end of the light-shielding film passes through the groove and is fixed to the second rotating rod. Both ends of the second rotating rod are mounted on the inner side of the other sleeve via bearings. One end of the second rotating rod is connected to the output end of a drive motor via a coupling. The drive motor is mounted on a first support plate. A support plate is fixed on the mounting frame. In order to reduce the harm caused by the strong light generated by the welding torch to the eyes of the workers and improve welding efficiency, a protective component is used. When the welding torch is used to weld the water pump, the strong light generated by the welding is blocked by the light shielding film on one side of the mounting frame, so as to avoid the strong light irritating the eyes of the workers. If the light shielding film is damaged by the sparks generated by the welding, the drive motor can be started. The damaged light shielding film can be rolled up by rotating the second rotating rod, and the light shielding film on the first rotating rod can be pulled out. The damaged light shielding film can be quickly replaced, thus providing a better protective working environment for the workers.
[0008] Preferably, the distance between the two sleeves is greater than the range of the strong light generated by the welding torch, which can better block the strong light generated by the welding torch and avoid irritating the eyes of the workers and causing damage.
[0009] Preferably, the fixing assembly includes a worktable and a drive assembly. A first fixing plate is fixed to the top side of the worktable. A second cylinder is installed on one side of the first fixing plate. A second piston rod is installed on the working end of the second cylinder. A first moving plate is fixed to the other end of the second piston rod. A clamping plate is fixed to one side of the first moving plate. Steel wire ropes are fixed to both sides of the first moving plate. When the second cylinder is activated to extend the second piston rod, the first moving plate pulls the steel wire ropes as it moves. Under the action of the pulley, the second moving plate moves towards the center simultaneously, fixing the water pump. This allows for the fixing and clamping of water pumps of different sizes, improving the practicality of the device and preventing the water pump from moving during welding and affecting the welding effect. When the second cylinder is activated to shorten the second piston rod, the steel wire ropes are no longer under force and will return to their position under the action of the return spring, releasing the fixing and clamping of the water pump.
[0010] Preferably, the drive assembly includes steel wire ropes, which are sleeved on a pulley on one side. A rotating shaft is fixed in the middle of the pulley, and both ends of the rotating shaft are mounted on a first U-shaped plate via bearings. The first U-shaped plate is fixed to a workbench, and the other ends of the two steel wire ropes are fixed to one side of a second moving plate. A clamping plate is fixed to one side of the second moving plate, and a telescopic rod is fixed to the other side of the second moving plate. The other end of the telescopic rod is fixed to a second fixed plate, and a return spring is sleeved on the outside of the telescopic rod. The two ends of the return spring are welded to the second moving plate and the second fixed plate, respectively. When the first moving plate moves, it pulls the steel wire ropes, which, under the action of the pulley, drive the second moving plate to move towards the center simultaneously. The telescopic rod extends, and the return spring is stretched, thus clamping the water pump. When it is necessary to release the clamping of the water pump, the second cylinder is activated to shorten the second piston rod. The steel wire ropes are no longer under force and will return to their position under the action of the return spring.
[0011] Preferably, the first and second movable plates are symmetrically distributed on the top side of the workbench, which can better fix and clamp water pumps of different sizes and improve the practicality of the device.
[0012] Preferably, the moving component includes a first connecting plate, a second U-shaped plate fixed to the bottom side of the first connecting plate, a lead screw mounted on the second U-shaped plate via a bearing, one end of the lead screw being connected to the output end of a servo motor via a coupling, the servo motor being mounted on a second support plate, the second support plate being fixed to the second U-shaped plate, a slider slidably mounted on the lead screw, a guide rod inserted into the bottom side of the slider, and both ends of the guide rod being fixed to the second U-shaped plate. Thus, after the water pump is fixed, starting the first cylinder and shortening the first piston rod can adjust the height of the welding torch. Then, starting the servo motor, the welding of the water pump is achieved by moving the slider on the lead screw.
[0013] The advantages of this utility model are:
[0014] 1. This utility model provides a welding device for water pump production. Through the structural design of the protective components, when welding a water pump with a welding torch, the strong light generated by welding can be blocked by a light-shielding film on one side of the mounting bracket, preventing the strong light from irritating the eyes of the workers. If the light-shielding film is damaged by the sparks generated by welding, the drive motor can be started, and the damaged light-shielding film can be rolled up by the rotation of the second rotating rod, and the light-shielding film on the first rotating rod can be pulled out, so that the damaged light-shielding film can be quickly replaced, thereby providing a better protective working environment for the workers.
[0015] 2. This utility model provides a water pump production welding device. Through the structural design of the fixing component, when the second cylinder is activated to extend the second piston rod, the first moving plate pulls the steel wire rope while moving. Under the action of the pulley, the second moving plate is driven to move towards the center at the same time to fix the water pump. This can fix and clamp water pumps of different sizes, improve the practicality of the device, and prevent the water pump from moving during welding and affecting the welding effect. When the second cylinder is activated to shorten the second piston rod, the steel wire rope is not under force and will return to its position under the action of the return spring, releasing the fixing clamp on the water pump.
