Description

Technical Field

[0001] This utility model relates to the field of welding head disassembly technology, and in particular to a welding device based on a detachable welding head for equipment manufacturing. Background Technology

[0002] Welding devices based on detachable welding heads for equipment manufacturing are widely used welding equipment in the equipment manufacturing field. They utilize the current output by the welding host to form a circuit through the electrodes of the detachable welding head, generating an electric arc between the electrode and the workpiece. The high temperature of the electric arc causes the workpiece to melt locally. At the same time, according to the needs of the welding process, the wire feeding mechanism feeds the welding wire into the welding area. The welding wire also melts under the action of the electric arc and fills the weld seam of the workpiece, forming a strong connection.

[0003] Detachable welding heads are fixed to other components via threaded and snap-fit ​​connections. However, these connections can loosen under the long-term effects of vibration and impact during the welding process. Loosening of the welding head changes its position and angle during welding, leading to unstable welding parameters and affecting welding quality. Existing technologies use high-strength bolts and nuts as fasteners, along with anti-loosening washers and thread-locking agents to ensure a secure and reliable connection between the welding head and other components. However, in actual use, the lack of a positioning device during welding head installation can cause the welding head to shift, resulting in decreased welding quality and affecting the product itself.

The connecting plate 9 is fixed to the bottom of the connecting block 6. The top of the outer wall of the two locking pins 10 is provided with round holes 11. The connecting rods 12 are slidably connected inside the two round holes 11. The connecting rods 12 pass through the round holes 11 to fix the locking pins 10 to the bottom of the connecting block 6. Fixing plates 13 are provided on the front and rear sides of the connecting rods 12. Multiple bolts 14 are threaded to the opposite sides of the two fixing plates 13. The fixing plates 13 are fixed to the outer wall of the connecting block 6 by the bolts 14, so that the connecting rods 12 will not fall off, thus allowing the welding head 15 to be installed quickly. The welding head 15 is fixedly connected to the bottom of the connecting plate 9. The top rear side of the base plate 1 is provided with an adjustment mechanism 2, which is used to adjust the height of the welding head 15.

[0033] Specifically, a controller 3 is installed on the top of the base plate 1. A telescopic rod 4 is fixedly connected to the top inner side of the controller 3. Under the control of the controller 3, the telescopic rod 4 can control the connecting sleeve 5 to move up and down. The bottom of the connecting sleeve 5 is fixedly connected to the connecting block 6. Two positioning holes 7 are opened at the bottom of the connecting block 6. When installing the welding head 15, two positioning pins 8 are inserted into the positioning holes 7 respectively to achieve initial positioning. The bottom of the positioning pins 8 is fixedly connected to the connecting plate 9. The bottom of the connecting plate 9 can be slidably connected to the locking pins 10 on both the front and rear sides. When the locking pins 10 slide into place, the connecting plate 9 can be fixed to the bottom of the connecting block 6. The top of the outer wall of column 10 is provided with a round hole 11. The connecting rod 12 passes through the round hole 11 to further stabilize the position of the column 10 at the bottom of the connecting block 6. To prevent the connecting rod 12 from falling off, fixing plates 13 are provided on its front and rear sides. Multiple bolts 14 are threaded to the opposite side of the two fixing plates 13. By tightening these bolts 14, the fixing plates 13 are fixed to the outer wall of the connecting block 6, and the connecting rod 12 is fixed. The whole installation process is convenient and efficient, thus realizing the rapid installation of the welding head 15. The bottom of the connecting plate 9 is fixedly connected to the welding head 15. After the installation is completed, the welding head 15 can be put into welding work.

[0034] Reference Figure 3 and Figure 6 The adjustment mechanism 2 includes a guide column 201. The bottom of the guide column 201 is fixedly connected to the top rear side of the base plate 1. The front and rear sides of the outer wall of the guide column 201 are fixedly connected to slide rails 202. The outer walls of the two slide rails 202 are slidably connected to fixing rings 203. The front and rear sides of the inner sides of the two fixing rings 203 are provided with grooves 204. The top rear side of the base plate 1 is fixedly connected to a hydraulic rod 205. The hydraulic rod 205 pushes the controller 3 to move up and down, so that the fixing rings 203 connected to the controller 3 can move on the slide rails 202 through the grooves 204, thereby adjusting the height of the welding head 15.

[0035] Specifically, a guide post 201 is fixed to the top rear side of the base plate 1. Slide rails 202 are installed on the front and rear sides of the outer wall of the guide post 201. Two fixing rings 203 are fitted on the slide rails 202 and can slide along them. The front and rear sides of the fixing rings 203 have grooves 204 that are adapted to the slide rails 202. At the same time, a hydraulic rod 205 is also provided on the top rear side of the base plate 1, which is connected to the controller 3. When the hydraulic rod 205 works and pushes the controller 3 to move up and down, the fixing rings 203 connected to the controller 3 will move on the slide rails 202 through the grooves 204, thereby realizing the precise adjustment of the height of the welding head 15 to meet different welding requirements.

[0036] Reference Figure 1 , Figure 2 and Figure 3A control panel 16 is fixedly connected to the front side of the base plate 1. Multiple buttons 17 are fixedly connected to the front side of the control panel 16 for controlling the device. Support columns 18 are fixedly connected to the four corners of the bottom of the base plate 1. Anti-slip sleeves 19 are fixedly connected to the bottom of the multiple support columns 18 to prevent the device from moving when it is started. An insertion sleeve 20 is fixedly connected to the rear right end of the controller 3. Multiple inserts 21 are fixedly connected to the front side of the inside of the insertion sleeve 20 for connecting wires.

[0037] Specifically, the control panel 16 is connected to the front of the base plate 1, and multiple buttons 17 are distributed on its surface. The operator can easily and accurately control the operation of the device through these buttons 17. Support columns 18 are installed at the four corners of the bottom of the base plate 1, and each support column 18 is covered with an anti-slip sleeve 19. This effectively prevents the device from shifting when it starts up and ensures stability. The rear right end of the controller 3 is connected to the insertion sleeve 20, and multiple inserts 21 are fixed inside the front, which facilitates connection with the power cord to connect the power supply and allow the device to operate smoothly.

[0038] Reference Figure 4 , Figure 5 and Figure 6 The controller 3 has a pressure groove 22 in the middle of the front side. The pointer 23 is rotatably connected to the rear side of the pressure groove 22 to show the pressure. The top of the two slide rails 202 is fixedly connected to the baffle 24 to prevent the fixing ring 203 from sliding out of the slide rail 202. The outer wall of the multiple bolts 14 is threaded with a washer 25 to prevent the bolts 14 from being tightened and unable to be opened. The diameter of the two positioning pins 8 is smaller than the diameter of the positioning hole 7. The two slide rails 202 match the groove 204.

[0039] Specifically, the controller 3 has a pressure groove 22 in the middle of the front side, and a pointer 23 is rotatably connected to the rear side inside it. The operator can intuitively read the current pressure value through the pointer 23 and control the welding status. A baffle 24 is installed on the top of the slide rail 202 of the guide column 201 to effectively prevent the fixing ring 203 from accidentally slipping out and to ensure the stability of the height adjustment structure. When installing the bolt 14, a washer 25 is threaded on its outer wall to avoid difficulty in disassembly due to over-tightening. The diameter of the two positioning pins 8 is smaller than that of the positioning hole 7, which makes it easy to insert and position. The slide rail 202 and the groove 204 are perfectly matched to ensure that the fixing ring 203 moves smoothly.

[0040] Working principle: The operator controls the telescopic rod 4 on the inner top through the controller 3, so that it can precisely control the up and down movement of the connecting sleeve 5. This is to prepare for the installation and position adjustment of the welding head 15. When installing the welding head 15, the connecting plate 9 with the positioning pin 8 is brought close to the connecting block 6, and the positioning pin 8 is inserted into the positioning hole 7 at the bottom of the connecting block 6 to achieve initial positioning. The locking pins 10 on the front and rear sides of the bottom of the connecting plate 9 are slid to lock into the corresponding position of the connecting block 6 to complete the initial fixation. The connecting rod 12 is passed through the round hole 11 at the top of the outer wall of the locking pin 10 to further fix the locking pin 10. Then, by tightening the bolts 14 on the fixing plate 13, the fixing plate 13 is fixed to the outer wall of the connecting block 6, thereby fixing the connecting rod 12 and completing the quick installation of the welding head 15.

[0041] Furthermore, when the hydraulic rod 205 is working, it generates thrust or pull through the internal hydraulic system. When the hydraulic rod 205 extends or retracts, it pushes or pulls the controller 3 connected to it to move up and down. Since the fixed ring 203 is connected to the controller 3, when the controller 3 is pushed up and down by the hydraulic rod 205, the fixed ring 203 also moves synchronously. The fixed ring 203 slides smoothly on the slide rail 202 through the groove 204, thereby driving the entire structure associated with the fixed ring 203, including the welding head 15, to move up and down. This achieves precise adjustment of the height of the welding head 15. Operators can flexibly adjust the height of the welding head 15 by controlling the working state of the hydraulic rod 205 according to different requirements such as the thickness of the welding workpiece and the welding position, so as to meet diverse welding process requirements and ensure welding quality and efficiency.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
