Description
Technical Field
[0001] The utility model relates to the technical field of laser welding, and particularly relates to a temperature switch laser welding head which is convenient to replace. Background Technique
[0002] A laser welding machine can also be called a laser welder or a laser welding machine, which is a machine used for laser welding of materials. Its principle is to use high-energy laser pulses to locally heat a small area of the material. The pulse allows the energy to expand into the interior of the material through heat conduction. After melting the material, welding operations are carried out. The advantages of laser welding are precise control, high precision, and easy automation.
[0003] Regarding the above related technologies, the inventor believes that there are the following defects: After the laser welding head is used for a long time, due to long-term welding, a large amount of welding raw materials will accumulate inside the welding head, and these welding raw materials will cause blockages. The existing welding gun head is fixed to the welding gun, and the staff cleans the welding head from the outside through cleaning tools, which increases the cleaning difficulty of the staff and thus reduces the work efficiency of the staff. Content of the Utility Model
[0004] In order to solve the above problems, the utility model provides a temperature switch laser welding head which is convenient to replace.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A temperature switch laser welding head which is convenient to replace, including a welding gun body, a welding head body is installed on the bottom surface of the welding gun body, a sliding groove is opened on the bottom surface of the welding gun body, a sliding rod is slidably arranged in the sliding groove, the sliding rod is fixed to the welding head body, and a fixing component for fixing the sliding rod is arranged on the welding gun body.
[0006] By adopting the above technical solutions, when the staff needs to weld an object, the staff needs to start the welding gun body, and then the welding head body welds the object. During this process, when the staff needs to replace the welding head, the staff needs to turn off the fixing component. Subsequently, the staff slides the sliding rod to separate the sliding rod from the sliding groove, and then the disassembly of the welding head can be completed, thereby reducing the difficulty of the staff in disassembling the welding head and thus improving the work efficiency of the staff.
[0007] Furthermore, a blocking groove is opened on the side wall of the sliding rod, a fixing groove is opened on the inner wall of the sliding groove, the fixing component includes a fixing block slidably arranged in the fixing groove and a first spring fixedly arranged on the side wall of the fixing block, the other end of the first spring is fixedly arranged on the inner wall of the fixing groove, and the fixing block is slidably connected with the blocking groove.
[0008] By adopting the above technical solution, when the staff needs to install the welding head body, the staff needs to slide the sliding rod into the sliding groove. During this process, the staff needs to slide the fixing block into the fixing groove to prevent the fixing block from blocking the sliding rod. Subsequently, when the sliding rod is completely slid into the sliding groove, the fixing groove is aligned with the blocking groove, and the fixing block slides towards the direction close to the blocking groove under the action of the first spring, so that one end of the fixing block slides into the blocking groove, thereby fixing the sliding rod in the sliding groove, and thus reducing the difficulty for the staff to install the welding head body.
[0009] Further, a first inclined surface is provided on the edge where the bottom surface of the fixing block intersects with the side wall away from the first spring, and a second inclined surface is provided on the edge where the side wall of the fixing block away from the first spring intersects with one of the adjacent side walls.
[0010] By adopting the above technical solution, when the staff slides the sliding rod into the sliding groove, the sliding rod gradually approaches and finally abuts against the first inclined surface, so that the fixing block slides into the fixing groove under the action of the sliding rod. During this process, there is no need for the staff to manually slide the fixing block, thereby reducing the work difficulty of the staff. In addition, when the staff needs to disassemble the sliding rod, the staff needs to rotate the welding head body, so that the sliding rod rotates under the action of the welding head body, so that the second inclined surface abuts against the inner wall of the blocking groove, and then the fixing block slides into the blocking groove. In addition, when the staff pulls the welding head body, the sliding rod can be slid out of the sliding groove, thereby reducing the difficulty for the staff to disassemble the welding head body.
[0011] Further, a limiting block is fixedly arranged on the inner wall of the sliding groove, a limiting groove is provided on the side wall of the sliding rod, and the limiting groove is slidably connected with the limiting block.
[0012] By adopting the above technical solution, when the staff needs to slide the sliding rod into the sliding groove, the staff needs to align the limiting block with the limiting groove. Subsequently, the staff slides the sliding rod into the sliding groove. During this process, when the sliding rod is completely slid into the sliding groove, the fixing groove is aligned with the blocking groove, thereby reducing the difficulty for the staff to align the fixing groove with the blocking groove.
[0013] Further, an annular groove is provided on the inner wall of the limiting groove, and the annular groove is rotatably connected with the limiting block.
[0014] By adopting the above technical solution, the annular groove reduces the probability that the limiting groove and the limiting groove are blocked when the staff rotates the sliding rod, thereby improving the stability of the device.
[0015] Further, a fixing rod is fixedly arranged on the inner wall of the blocking groove away from the fixing groove, a fixing hole is provided on the side wall of the fixing block away from the first spring, and the fixing rod and the fixing hole are matched with each other.
[0016] By adopting the above technical solution, the fixed rod and the fixed hole reduce the probability of the sliding rod shaking during use, thereby reducing the probability of the welding head body shaking, and thus improving the stability of the device.
[0017] Furthermore, the fixed rod is a fixed rod made of rubber material.
[0018] By adopting the above technical solution, the fixed rod made of rubber material reduces the probability of the fixed rod blocking the fixed block when the staff rotates the sliding rod, thereby improving the stability of the device.

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0030] As Figures 1-5 shown, an embodiment of the present application discloses a temperature switch laser welding head that is easy to replace, including a welding torch body 1, a welding head body 11, a sliding rod 13, a fixing component 3, and a limiting block 5. The welding torch body 1 (only the connection mechanism between the welding head body 11 and the welding torch body 1 is shown in the figure, so the complete form of the welding torch body 1 is not fully shown), and a sliding groove 12 is opened on the bottom surface of the welding torch body 1. The welding head body 11 is installed on the bottom surface of the welding torch body 1. The sliding rod 13 is in a round rod shape structure, its axis is vertical, the sliding rod 13 is slidably arranged in the sliding groove 12, and the sliding rod 13 is fixed to the welding head body 11.
[0031] When the staff needs to weld an item, the staff needs to start the welding torch body 1, and then the welding head body 11 welds the item. During this process, when the staff needs to replace the welding head, the staff needs to turn off the fixing component 3. Subsequently, the staff slides the sliding rod 13 to separate the sliding rod 13 from the sliding groove 12, and then the disassembly of the welding head can be completed, thereby reducing the difficulty of the staff in disassembling the welding head and improving the work efficiency of the staff.
[0032] A blocking groove 2 is formed on the side wall of the sliding rod 13, and a fixing groove 21 is formed on the inner wall of the sliding groove 12. A fixing assembly 3 is arranged on the welding torch body 1 for fixing the sliding rod 13. The fixing assembly 3 includes a fixing block 31 and a first spring 32. The fixing block 31 is slidably arranged in the sliding groove 12, and the fixing block 31 is slidably connected with the blocking groove 2. One end of the first spring 32 is fixedly arranged on the side wall of the fixing block 31, and the other end of the first spring 32 is fixedly arranged on the inner wall of the fixing groove 21.
[0033] When the staff needs to install the welding head body, the staff needs to slide the sliding rod 13 into the sliding groove 12. During this process, the staff needs to slide the fixing block 31 into the fixing groove 21 to prevent the fixing block 31 from blocking the sliding rod 13. Subsequently, when the sliding rod 13 is completely slid into the sliding groove 12, the fixing groove 21 is aligned with the blocking groove 2, and the fixing block 31 slides in the direction close to the blocking groove 2 under the action of the first spring 32. Then, one end of the fixing block 31 slides into the blocking groove 2, thereby fixing the sliding rod 13 in the sliding groove 12, and thus reducing the difficulty for the staff to install the welding head body.
[0034] A first inclined surface 4 is formed on the edge where the bottom surface of the fixing block 31 intersects with the side wall away from the first spring 32, and a second inclined surface 41 is formed on the edge where the side wall of the fixing block 31 away from the first spring 32 intersects with one of the adjacent side walls.
[0035] When the staff slides the sliding rod 13 into the sliding groove 12, the sliding rod 13 gradually approaches and finally abuts against the first inclined surface 4, so that the fixing block 31 slides into the fixing groove 21 under the action of the sliding rod 13. During this process, there is no need for the staff to manually slide the fixing block 31, thus reducing the work difficulty of the staff. In addition, when the staff needs to disassemble the sliding rod 13, the staff needs to rotate the welding head body, so that the sliding rod 13 rotates under the action of the welding head body, thereby making the second inclined surface 41 abut against the inner wall of the blocking groove 2, and then making the fixing block 31 slide into the blocking groove 2. In addition, the staff can pull the welding head body to make the sliding rod 13 slide out of the sliding groove 12, thus reducing the difficulty for the staff to disassemble the welding head body.
[0036] A limiting groove 51 is formed on the side wall of the sliding rod 13, and a limiting block 5 is fixedly arranged on the inner wall of the sliding groove 12. The limiting groove 51 is slidably connected with the limiting block 5.
[0037] When the staff needs to slide the sliding rod 13 into the sliding groove 12, the staff needs to align the limiting block 5 with the limiting groove 51. Subsequently, the staff slides the sliding rod 13 into the sliding groove 12. During this process, when the sliding rod 13 is completely slid into the sliding groove 12, the fixing groove 21 is aligned with the blocking groove 2, thus reducing the difficulty for the staff to align the fixing groove 21 with the blocking groove 2.
[0038] To improve the stability of the device, a circular groove 6 is formed on the inner wall of the limit groove 51, and the circular groove 6 is rotatably connected to the limit block 5. The circular groove 6 reduces the probability that the limit groove 51 and the limit groove 51 block each other when the staff rotates the sliding rod 13, thereby improving the stability of the device.
[0039] To improve the stability of the device, a fixing rod 7 is fixedly arranged on the inner wall of the blocking groove 2 far from the fixing groove 21. A fixing hole 71 is formed on the side wall of the fixing block 31 far from the first spring 32, and the fixing rod 7 and the fixing hole 71 are mutually matched. The fixing rod 7 and the fixing hole 71 reduce the probability that the sliding rod 13 shakes during use, and further reduce the probability that the welding head body 11 shakes, thereby improving the stability of the device.
[0040] To improve the stability of the device, the fixing rod 7 is made of rubber. The fixing rod 7 made of rubber reduces the probability that the fixing rod 7 blocks the fixing block 31 when the staff rotates the sliding rod 13, thereby improving the stability of the device.
[0041] The working principle of a temperature switch laser welding head that is easy to replace in this embodiment is as follows: When the staff needs to weld an item, the staff needs to start the welding torch body 1, and then the welding head body 11 welds the item. During this process, when the staff needs to replace the welding head, the staff needs to rotate the welding head main body, and then the sliding rod 13 rotates under the action of the welding head main body, so that the second inclined surface 41 abuts against the inner wall of the blocking groove 2, and then the fixing block 31 slides into the blocking groove 2. In addition, when the staff pulls the welding head main body, the sliding rod 13 can be slid out of the sliding groove 12 to complete the disassembly of the welding head body 11. Subsequently, when the staff needs to install the welding head main body, the staff needs to slide the sliding rod 13 into the sliding groove 12. The sliding rod 13 gradually approaches and finally abuts against the first inclined surface 4, and then the fixing block 31 slides into the fixing groove 21 under the action of the sliding rod 13. Subsequently, when the sliding rod 13 completely slides into the sliding groove 12, the fixing groove 21 and the blocking groove 2 are aligned. The fixing block 31 slides in the direction close to the blocking groove 2 under the action of the first spring 32, and then one end of the fixing block 31 slides into the blocking groove 2, thereby fixing the sliding rod 13 in the sliding groove 12, and further reducing the difficulty for the staff to install the welding head main body.
[0042] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
