Description

Technical Field

[0001] The utility model belongs to the field of welding processing of water outlet pipe joints, and more specifically relates to a water outlet pipe joint welding device. Background Art

[0002] The elbow faucet is a relatively common faucet for kitchen and bathroom use. Compared with the traditional straight faucet, the main feature of the elbow faucet is that the water outlet is designed in a bent shape, making the water flow softer and enabling more precise control of the direction and arc of the water flow.

[0003] As Figure 1 shown, in an elbow faucet in the prior art, the pipe body and the water outlet end are butted and welded together at the butting position by a welding machine, and usually a filter element is threadedly connected to the water outlet end.

[0004] For elbow faucets similar to the above in the prior art, when welding the pipe body and the water outlet end, a full-circle welding is required. The welder needs to hold the pipe body by hand, turn the pipe body over after welding half a circle, and then perform the welding of the other half circle. During the welding process, the welder is prone to problems such as hand shaking, resulting in welding quality problems and low welding efficiency. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a water outlet pipe joint welding device, which has the advantages of convenient welding, improved welding quality and efficiency.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A water outlet pipe joint welding device includes a workbench, a laser welding machine installed on the workbench, and a base located below the laser spot welding machine;

[0008] A clamping device is installed on the base for clamping and fixing the elbow faucet. The clamping device includes: a cylinder, a rotating pipe, a clamping head and a telescopic rod. The rotating pipe is rotatably installed on the base. The clamping head is installed at one end of the rotating pipe. The cylinder is installed on the side wall of the base frame. The output end of the cylinder extends into the base, and a pushing block is rotatably installed at its output end. The telescopic rod is installed in the rotating pipe. One end of the telescopic rod is connected to the pushing block, and the other end extends out of the rotating pipe. A clamping block is fixed at the end of the telescopic rod extending out of the rotating pipe. The outer diameter of the clamping block is larger than the inner diameter of the clamping head;

[0009] A driving device is installed below the clamping device for driving and rotating the clamping device.

[0010] The advantages of this solution are at least that: when it is necessary to weld the pipe body and the water outlet end, one end of the pipe body that is connected to the water outlet end is mounted on the outer wall of the clamping head, and the cylinder is started, which drives the pushing block and the telescopic rod to move to the left. At this time, the clamping block also moves to the left to the inside of the clamping head. Since the outer diameter of the clamping block is larger than the inner diameter of the clamping head, the pipe diameter of the clamping head will expand when the clamping block enters the inside of the clamping head, thereby fixing the pipe body on the clamping head. Then the driving device is started to rotate the rotating tube and the pushing block. At this time, the laser spot welding machine welds the pipe body and the water outlet end at the docking position, making welding more convenient and quick, avoiding the problem of hand shaking of welders in the welding process of the prior art, thereby improving welding quality and welding efficiency.

[0011] The utility model is further configured as follows: the driving device includes: a motor, a reducer located at the output end of the motor and a rotating shaft, the output end of the reducer extends into the base, the output end of the reducer is connected to the rotating shaft through a coupling, the rotating shaft is rotatably installed on the base, pulleys are provided on the rotating shaft and the rotating tube, and a belt is installed between the two pulleys.

[0012] The utility model is further configured as follows: the clamping block and the telescopic rod are integrally formed, and the cross-sectional area of ​​the clamping block is trapezoidal.

[0013] The advantages of this solution are at least that the clamping block and the telescopic rod are integrally formed, which increases the connection strength between the clamping block and the telescopic rod; and the cross-sectional area of ​​the clamping block is trapezoidal, which is more convenient for the clamping block to enter the interior of the clamping head than the cross-sectional area of ​​the clamping block is rectangular, thus avoiding jamming of the clamping block when entering the interior of the clamping head.

[0014] The utility model is further configured as follows: a protruding block is provided on the outer wall of the clamping head that contacts the inner wall of the tube body.

[0015] The advantage of this solution is at least that when the clamping block enters the interior of the clamping head, the arrangement of the protruding block relative to the arrangement without the protruding block can make the tube body more firmly fixed on the clamping head.

[0016] The utility model is further configured as follows: a threaded hole is arranged around the outer wall of the rotating tube, a bolt is threadedly connected to the threaded hole, and the clamping head is detachably mounted on the rotating tube.

[0017] The advantage of this solution is at least that the clamping head is fixed to the rotating tube by bolts. When welding of the joints of pipe bodies and water outlet ends of different diameters is required later, the clamping head can be replaced by simply loosening the bolts, thereby increasing the applicability of the welding device.

[0018] The utility model is further configured as follows: a thread is arranged at one end of the telescopic rod away from the clamping block, and the telescopic rod is threadedly connected to the pushing block.

[0019] The advantages of this solution are at least that the telescopic rod is fixed to the pushing block by means of a threaded connection. On the one hand, when welding is required for the butt joints between the pipe body and the water outlet end of different diameters, it is convenient to replace the telescopic rod and the clamping block matched with the clamping head. On the other hand, when the telescopic rod is worn or damaged, it is convenient to repair and replace it.

[0020] The utility model is further configured as follows: two mounting plates are arranged on the base, and mounting holes are opened on the mounting plates.

[0021] The advantage of this solution is at least that the provision of the mounting plate facilitates the installation of the base on the laser spot welding machine, thereby avoiding the need for the base to be fixed by means of a pressing plate.

[0022] In summary, the utility model has at least the following advantages:

[0023] 1. By setting a clamping device and a driving device, when it is necessary to weld the pipe body and the water outlet end, one end of the pipe body that is connected to the water outlet end is sleeved on the outer wall of the clamping head, and the cylinder is started, and the cylinder drives the push block and the telescopic rod to move to the left. At this time, the clamping block also moves to the left to the inside of the clamping head. Since the outer diameter of the clamping block is larger than the inner diameter of the clamping head, the pipe diameter of the clamping head will be expanded when the clamping block enters the inside of the clamping head, thereby fixing the pipe body on the clamping head, and then starting the driving device to rotate the rotating pipe and the pushing block. At this time, the laser spot welding machine welds the pipe body and the water outlet end at the docking position, making welding more convenient and quick, avoiding the problem of hand shaking of welders in the welding process of the prior art, thereby improving welding quality and welding efficiency;

[0024] 2. By forming the clamping block and the telescopic rod into one piece, the connection strength between the clamping block and the telescopic rod is increased. The cross-sectional area of ​​the clamping block is trapezoidal, which is more convenient for the clamping block to enter the interior of the clamping head than the cross-sectional area of ​​the clamping block is rectangular, thus avoiding the clamping block from getting stuck when entering the interior of the clamping head. By setting the raised block, when the clamping block enters the interior of the clamping head, the setting with the raised block is relatively better than that without the raised block, so that the tube body can be more firmly fixed on the clamping head.

[0025] 3. The clamping head is detachably mounted on the rotating tube by bolts. When it is necessary to weld the butt joints of pipe bodies and water outlet ends of different diameters in the future, the clamping head can be replaced by simply loosening the bolts, thereby increasing the applicability of the welding device. The telescopic rod is fixed to the pushing block by threaded connection. On the one hand, when it is necessary to weld the butt joints of pipe bodies and water outlet ends of different diameters, it is convenient to replace the telescopic rod and the clamping block matched with the clamping head. On the other hand, when the telescopic rod is worn or damaged, it is convenient to repair and replace it. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0034] A water outlet pipe joint welding device, such as Figure 2 As shown, it includes a workbench 1, a laser electric welder installed on the workbench 1, and a base 3 located below the laser spot welder 2. Two mounting plates 12 are provided on the base 3, and mounting holes 13 are opened on the mounting plates 12. The laser spot welder 2 belongs to the prior art, which can weld joints remotely by laser.

[0035] like Figure 3 ,Figure 4 As shown in the figure, a clamping device 4 is installed on the base 3 for clamping and fixing the elbow faucet. The clamping device 4 includes: a cylinder 401, a rotating tube 402, a clamping head 403, and a telescopic rod 404. The rotating tube 402 is rotatably installed on the base 3. The clamping head 403 is installed at one end of the rotating tube 402. The cylinder 401 is installed on the side wall of the base frame. The output end of the cylinder 401 extends into the base 3, and a pushing block 405 is rotatably installed at its output end. The telescopic rod 404 is installed in the rotating tube 402. One end of the telescopic rod 404 is connected to the pushing block 405, and the other end extends out of the rotating tube 402. A clamping block 406 is fixed at the end of the telescopic rod 404 extending out of the rotating tube 402. The outer diameter of the clamping block 406 is larger than the inner diameter of the clamping head 403.

[0036] It is worth mentioning that the clamping block 406 and the telescopic rod 404 are integrally formed, which increases the connection strength between the clamping block 406 and the telescopic rod 404. Moreover, the cross-sectional area of the clamping block 406 is trapezoidal. The cross-sectional area of the clamping block 406 being trapezoidal is more convenient for the clamping block 406 to enter the inside of the clamping head 403 compared to a rectangular cross-sectional area, avoiding jamming when the clamping block 406 enters the inside of the clamping head 403.

[0037] As Figure 4 shown, a driving device 5 is installed below the clamping device 4 for driving the clamping device 4 to rotate. The driving device 5 includes: a motor 501, a reducer 502 located at the output end of the motor 501, and a rotating shaft 503. The output end of the reducer 502 extends into the base 3. The output end of the reducer 502 is connected to the rotating shaft 503 through a coupling 6. The rotating shaft 503 is rotatably installed on the base 3. Pulley 7 is provided on both the rotating shaft 503 and the rotating tube 402, and a belt 8 is installed between the two pulleys 7.

[0038] As Figure 5 、 Figure 6As shown in the figure, in order to fix the pipe body 14 more firmly on the clamping head 403, in some embodiments, a raised block 9 is provided on the outer wall of the clamping head 403 that contacts the inner wall of the pipe body 14. A threaded hole 10 is provided around the outer wall of the rotating pipe 402, and a bolt 11 is threadedly connected to the threaded hole 10. The clamping head 403 is detachably installed on the rotating pipe 402, which facilitates the replacement of the clamping head 403 when welding the docking positions of pipe bodies 14 with different diameters and the water outlet end 15 in the subsequent process. One end of the telescopic rod 404 away from the clamping block 406 is threaded, and the telescopic rod 404 is threadedly connected to the pushing block 405. Fixing the telescopic rod 404 to the pushing block 405 by means of threaded connection, on the one hand, when welding the docking positions of pipe bodies 14 with different diameters and the water outlet end 15, it is convenient to replace the telescopic rod 404 and the clamping block 406 that are matched with the clamping head 403; on the other hand, when the telescopic rod 404 is worn or damaged, it is convenient to repair and replace it.

[0039] The working process and beneficial effects of the present utility model are as follows:

[0040] When welding the pipe body 14 and the water outlet end 15, the end of the pipe body 14 that is docked with the water outlet end 15 is sleeved on the outer wall of the clamping head 403. By starting the cylinder 401, the cylinder 401 drives the pushing block 405 and the telescopic rod 404 to move leftward. At this time, the clamping block 406 also moves leftward into the interior of the clamping head 403. Since the outer diameter of the clamping block 406 is larger than the inner diameter of the clamping head 403, when the clamping block 406 enters the interior of the clamping head 403, the diameter of the clamping head 403 will be expanded, and under the action of the raised block 9, the pipe body 14 is fixed more firmly on the clamping head 403. Then, start the driving device 5 to make the rotating pipe 402 and the pushing block 405 rotate on the base 3. At this time, the laser spot welder 2 welds the docking position of the pipe body 14 and the water outlet end 15, making the welding more convenient and fast, avoiding problems such as the welder's hand shaking easily during the welding process in the prior art, thereby improving the welding quality and welding efficiency.

[0041] When welding the docking positions of pipe bodies 14 with different diameters and the water outlet end 15, loosen the bolt 11 to remove the clamping head 403 from the rotating pipe 402, and screw the telescopic rod 404 and the clamping block 406 off the pushing block 405, so as to replace the clamping head 403 and the telescopic rod 404 and the clamping block 406 that are matched with it, thereby increasing the applicability of the welding device.

[0042] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
