[0024] Specifically, the clamping assembly 5 includes a clamping plate 51, a fixing member 52, a cavity 53, a connecting spring 54 and a moving rod 55. The cavity 53 is provided on both sides of the interior of the mounting plate 1. The moving rod 55 is inserted into the interior of the cavity 53.

The fixing member 52 is provided between the clamping plate 51 and the mounting plate 1.

[0025] By adopting the above technical solution, the mounting plate 1 is moved and fitted to the mounting position of the laser welding head, and the laser welding head is passed through the through hole 2. During the moving and fitting process, the clamping plate 51 is moved by the squeezing effect of the mounting position of the laser welding head. The movement of the clamping plate 51 drives the moving rod 55 to move inside the cavity 53. The movement of the moving rod 55 drives the connecting spring 54 to stretch. When the mounting plate 1 is completely fitted to the mounting position of the laser welding head, the fixing member 52 is used to fix the clamping plate 51. The clamping plate 51 can be used to install the entire device to the periphery of the laser welding head, which is convenient for the disassembly and assembly of the entire device.

[0026] Specifically, both sides of the end of the moving rod 55 close to the connecting spring 54 are connected to the limit sliders, and the inner wall of the cavity 53 is provided with a limit slide groove at the position corresponding to the limit slider.

[0027] By adopting the above technical solution, the movement of the moving rod 55 drives the limiting slider to move inside the limiting slide groove. When the limiting slider moves to fit the side wall of the limiting slide groove, the limiting slider is blocked and stops moving, thereby preventing the moving rod 55 from leaving the cavity 53.

[0028] Specifically, the fixing member 52 includes a fixing screw 521, a connecting rod 522, an L-shaped rod 523, a rotating nut 524 and an end plate 525. The end plate 525 is connected to the lower side of the mounting plate 1. One end of the end plate 525 is connected to the fixing screw 521. The L-shaped rod 523 is sleeved on the periphery of the fixing screw 521. The rotating nut 524 is connected to the outer wall of the fixing screw 521 and located on one side of the L-shaped rod 523. The connecting rod 522 is connected between the clamping plate 51 and the L-shaped rod 523.

[0029] By adopting the above technical solution, the movement of the clamping plate 51 drives the connecting rod 522 to move, and the movement of the connecting rod 522 drives the L-shaped rod 523 to move on the fixed screw 521. When the clamping plate 51 is in contact with the side wall of the installation site of the laser welding head, the rotating nut 524 is rotated to rotate and move along the fixed screw 521. When the rotating nut 524 is in contact with the side wall of the L-shaped rod 523, the rotation of the rotating nut 524 is stopped. Under the action of the rotating nut 524, the L-shaped rod 523 can be fixed, and then the connecting rod 522 and the clamping plate 51 can be fixed.

[0030] When the present embodiment is used, when it is necessary to perform a protective operation on the laser welding head, the mounting plate 1 is moved and fitted to the mounting position of the laser welding head, and the laser welding head is passed through the through hole 2. During the moving and fitting process, the clamping plate 51 is moved by the squeezing effect of the mounting position of the laser welding head, and the movement of the clamping plate 51 drives the moving rod 55 to move inside the cavity 53, and the movement of the moving rod 55 drives the connecting spring 54 to stretch. When the mounting plate 1 is completely fitted to the mounting position of the laser welding head, the rotating nut 524 is rotated to rotate and move along the fixing screw 521. When the rotating nut 524 fits the side wall of the L-shaped rod 523, the rotation of the rotating nut 524 is stopped. The clamping plate 51 can be used to install the entire device to the periphery of the laser welding head, which is convenient for the disassembly and assembly of the entire device. Under the action of the protective shell 3 and the telescopic shell 4, it can be avoided that the laser welding head is not needed. The collision between the laser welding head and external objects can be avoided, thereby avoiding damage to the laser welding head.

[0031] Example 2

[0032] The present embodiment is different from the embodiment 1 in that the purification assembly 7 includes a placement cylinder 71, activated carbon 72, an annular cavity 73 and adsorption holes 76. The protective shell 3 is provided with an annular cavity 73, the annular cavity 73 is provided with a placement cylinder 71, the placement cylinder 71 is filled with activated carbon 72, and the side wall of the placement cylinder 71 is provided with a plurality of adsorption holes 76.

[0033] Specifically, the purification component 7 further includes a connecting tube 74 and a connecting groove 75. The end of the placement tube 71 close to the annular cavity 73 is connected to the connecting tube 74. The connecting groove 75 is provided on the side wall of the annular cavity 73 at a position corresponding to the connecting tube 74.

[0034] By adopting the above technical solution, the placement tube 71 is inserted into the annular cavity 73, and the connecting tube 74 is then inserted into the connecting groove 75, and then force is applied to drive the placement tube 71 to rotate. The rotation of the placement tube 71 drives the connecting tube 74 to rotate and screw into the connecting groove 75, thereby facilitating the disassembly and assembly operation of the placement tube 71.

[0035] When this embodiment is used, the placement tube 71 is inserted into the annular cavity 73, and the connecting tube 74 is then inserted into the connecting groove 75, and then force is applied to drive the placement tube 71 to rotate. The rotation of the placement tube 71 drives the connecting tube 74 to rotate and screw into the connecting groove 75. When a laser welding head is needed to perform welding operations later, the welding equipment is used to drive the laser welding head to move downward, and then the telescopic shell 4 can be driven to move downward. When the telescopic shell 4 fits the side wall of the welding object, the telescopic shell 4 is squeezed and moves toward the inside of the protective shell 3. Under the action of the protective shell 3 and the telescopic shell 4, the laser welding head can be sealed. The odor generated during the welding process enters the placement tube 71 through the adsorption hole 76 and is adsorbed and purified by the activated carbon 72, thereby preventing the subsequent odor from spreading to the external environment and causing pollution to the surrounding environment, thereby improving the use effect of the entire device.

[0036] The structure and principle of the connecting mechanism 6 composed of a fastening bolt, a fixing plate, a limiting column and a compression spring in the utility model have been disclosed in a protective device for a laser welding head disclosed in Chinese patent application No. 202222696247.4, and its working principle is: a threaded hole is opened on the side of the telescopic shell 4, and the internal thread of the threaded hole is connected with a fastening bolt, the inner wall of the telescopic shell 4 and the outer wall of the protective shell 3 are fixed with a fixing plate, the surface of the fixing plate is fixed with a limiting column, and the external fixed sleeve of the limiting column is connected with a compression spring, and the compression spring can make the telescopic shell 4 contract when the fastening bolt is loosened under the condition of being subjected to an upward external force, and return to its original position through the compression spring when there is no external force.

[0037] The working principle and use process of the utility model are as follows: the utility model inserts the placement tube 71 into the annular cavity 73, and the connecting tube 74 is then inserted into the connecting groove 75, and then force is applied to drive the placement tube 71 to rotate. The rotation of the placement tube 71 drives the connecting tube 74 to rotate and screw into the connecting groove 75. When the laser welding head needs to be protected, the mounting plate 1 is moved to fit the mounting position of the laser welding head, and the laser welding head is passed through the through hole 2. During the moving and fitting process, the clamping plate 51 is moved by the squeezing effect of the mounting position of the laser welding head. The movement of the clamping plate 51 drives the moving rod 55 to move inside the cavity 53. The movement of the moving rod 55 drives the connecting spring 54 to stretch. When the mounting plate 1 is completely fitted to the mounting position of the laser welding head, the rotating nut 524 is rotated to make it rotate and move along the fixing screw 521. When the rotating nut 524 fits the side wall of the L-shaped rod 523, the rotating nut is stopped. 524. The entire device can be installed on the periphery of the laser welding head by using the clamping plate 51, which is convenient for the assembly and disassembly of the entire device. Under the action of the protective shell 3 and the telescopic shell 4, it can avoid collision between the laser welding head and external objects when the laser welding head is not needed, thereby avoiding damage to the laser welding head. When the laser welding head is needed to perform welding operations, the laser welding head is driven downward by the welding equipment, thereby driving the telescopic shell 4 downward. When the telescopic shell 4 fits the side wall of the welding object, the telescopic shell 4 is squeezed and moves toward the inside of the protective shell 3. Under the action of the protective shell 3 and the telescopic shell 4, the laser welding head can be sealed. The odor generated during welding enters the inside of the placement tube 71 through the adsorption hole 76, and is adsorbed and purified by the activated carbon 72, thereby avoiding the subsequent odor from spreading to the external environment and causing pollution to the surrounding environment, thereby improving the use effect of the entire device.
