[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 the material in a linear or dot-shaped area. The pulse allows the energy to expand into the interior of the material through heat conduction, melts the material and then performs the welding operation. The advantages of laser welding are that it can be precisely controlled, has high precision and is easy to automate.

The laser head of the laser welding machine is the part with the greatest wear and tear in the whole equipment and its function is also the most important. The existing laser head replacement is relatively complex and not easy to install, with a long replacement time and consuming a lot of manpower, resulting in troublesome maintenance. At the same time, after the laser head is removed, dust and other impurities are likely to enter the lower end of the laser seat, affecting the components inside the laser seat and leading to a decrease in service life.

[0060] As Figure 20 shown, the shape of the formed product 54 after winding is a conical barrel shape, and the formed product 54 is located in the semi-conical groove 40 of the forming seat 37. When the formed product 54 is formed, the conical barrel-shaped formed product 54 is kept inclined, and the originally inclined outer wall is set horizontally to facilitate the extrusion forming and welding work.

[0061] The welding assembly 30 is provided with a laser base 61 and a laser head 55. At the lower end of the laser base 61, an installation chamber 62 is formed. The installation chamber 62 can install the laser head 55 and a limiting member 63, and at the same time can keep the limiting member 63 rotating therein. When the laser head 55 is not inserted into the internal installation of the laser base 61, at this time, the limiting member 63 closes the opening of the installation chamber 62, that is, the guiding block 64 of the limiting member 63 acts on the bottom plate 65, and the limiting member 63 is supported by the bottom plate 65, and at the same time, the effect of dust-proof sealing is achieved.

[0062] A limiting member 63 is hinged in the installation chamber 62. The limiting member 63 is composed of a limiting plate 66 and an elastic arm 67. An elastic region 68 is formed between the elastic arm 67 and the limiting plate 66. One end of the limiting plate 66 is provided with a hinged end 69, and the other end is provided with a locking end 70. The locking end 70 cooperates with a locking groove 71. The laser base 61 is provided with a hinged hole 72, and the hinged end 69 is provided with a hinged rod 73 that cooperates with the hinged hole 72. The limiting member 63 can rotate in the installation chamber 62 of the laser base 61 through the hinged rod 73. When the laser head 55 is installed, only the limiting member 63 needs to be pushed, so that the limiting member 63 rotates around the hinged rod 73, and with the cooperation of the elastic arm 67, the limiting member 63 is forced to contact the inner wall of the installation chamber 62. After the laser head 55 is inserted, the locking end 70 can enter the locking groove 71 to support and limit the laser head 55 so that it will not fall off, and at the same time, the installation operation of the laser head 55 is completed.

[0063] The laser head 55 is provided with an unlocking member 74 and a locking groove 71 that cooperates with the limiting member 63. The laser head 55 is inserted into the installation chamber 62 from the bottom of the laser base 61, and the limiting member 63 is pushed to rotate through the laser head 55, and the limiting member 63 is kept in cooperation and limited with the locking groove 71.

The rubber ring 77 can limit the position of the unlocking member 74. At the same time, when the laser head 55 is installed inside the installation chamber 62, it can be elastically buffered. At the same time, it is also convenient to push the laser head 55 upward by a certain distance when disassembling the laser head 55, so that the rubber ring 77 is forced to be extruded and deformed, and the limiting member 63 can be pushed by the unlocking member 74 to disengage from the locking groove 71.

[0065] A sliding groove 79 is provided on one side of the docking end 75. The unlocking member 74 is arranged in the sliding groove 79. The locking grooves 71 are arranged on both sides of the sliding groove 79. The depth of the sliding groove 79 is greater than the depth of the locking groove 71, which is convenient for the unlocking member 74 to push the locking end 70, so that the unlocking member 74 can push the limiting member 63 to rotate around the hinged rod 73 and push the locking end 70 out of the locking groove 71.

[0066] The unlocking member 74 is composed of a sliding portion 80 and a pushing portion 81, and the sliding portion 80 is perpendicularly arranged with the pushing portion 81. The sliding portion 80 is arranged in the sliding groove 79, and symmetrically arranged T-shaped grooves 82 are provided on the sliding portion 80, and T-shaped blocks 83 matched with the T-shaped grooves 82 are provided in the sliding groove 79. Through the cooperation of the T-shaped grooves 82 and the T-shaped blocks 83, it is realized that the position of the unlocking member 74 can only move up and down and will not move out of the sliding groove 79.

[0067] A blocking surface 84 is provided in the locking groove 71, and a guiding surface 85, an arc surface 86, a contact surface 87 and a mating surface 88 in contact with the blocking surface 84 are provided on the locking end 70. A horizontal surface 89 and a guiding inclined surface 90 are provided on the unlocking member 74, and the guiding inclined surface 90 is matched with the guiding surface 85. When the unlocking member 74 is pushed upward, it can move along with the guiding inclined surface 90, push the guiding surface 85 on the locking end 70, and then move the entire locking end 70 out of the locking groove 71, so that the limiting member 63 no longer blocks the laser head 55, and the laser head 55 can be taken out and replaced.

[0068] The elastic arm 67 is composed of an arc section 91, a contact section 92 and a limiting section 93. The limiting section 93 is perpendicularly arranged with the contact section 92, and an activity gap 94 is formed between the limiting section 93 and the limiting plate 66. The activity gap 94 can prevent the limiting plate 66 from being pushed excessively and limit the moving stroke of the limiting plate 66.

[0069] Guide blocks 64 are provided on both sides of the limiting plate 66, and guide arc grooves 95 matched with the guide blocks 64 are provided on the inner wall of the installation chamber 62. A bottom plate 65 is provided at the lower end of the laser seat 61, and a through hole 96 matched with the laser head 55 is provided in the middle of the bottom plate 65. The guide blocks 64 are placed on the bottom plate 65. The guide blocks 64 can enable the limiting member 63 to move along the track of the guide arc groove 95, ensure the stability of rotation, and at the same time, cooperate with the guide blocks 64 to be placed on the bottom plate 65, support the limiting member 63 through the bottom plate 65, and play a sealing role to prevent dust and impurities during external welding from entering the laser seat 61 after the laser head 55 is disassembled, affecting the normal operation of laser welding.
