[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0022] As attached Figures 1 to 4The welding fixture shown is convenient for removing components, including a reference plate 1, which is made of alloy steel. The reference plate 1 is provided with three groups of through holes 3 arranged in a triangle in the vertical direction for installing horizontal positioning pins 4. This geometric layout provides extremely high stability and symmetry, ensuring that the position of the workpiece is accurate during the welding process. The bottom of the reference plate 1 is provided with a receiving plate 2, which is also made of alloy steel. The vertical positioning pins 8 and the control ribs 9 arranged on the receiving plate 2 are used to realize the component 11 during welding. Three-dimensional precise positioning is performed during the process to prevent the component 11 from being misplaced during the welding process. Through holes 3 are provided on the outer wall of the reference plate 1. There are three groups of through holes 3, and the three groups of through holes 3 are arranged in a triangle along the vertical direction of the reference plate 1. The through holes 3 are drilled using a high-precision drilling machine to ensure the aperture accuracy and surface finish. The through holes 3 provide precise guidance and support for the horizontal positioning pin shaft 4 to ensure that the position of the component 11 is accurate during the welding process. At the same time, a certain gap should be reserved for the through holes 3 to adapt to the temperature changes during the welding process.

[0023] The cross positioning pin 4 is provided inside the through hole 3, and the cross positioning pin 4 is made of high-hardness metal material. This precisely machined positioning pin ensures the repeatability of each welding. The cross positioning pin 4 can quickly enter the through hole 3, realize the instant positioning of the workpiece, and greatly improve the efficiency of welding preparation. A movable plate 5 is provided on one side of the cross positioning pin 4, and the movable plate 5 is also made of alloy steel. The movable plate 5 is tightly combined with the cross positioning pin 4, and can quickly position the component 11 in the welding preparation stage. By working in coordination with the reference plate 1 and the receiving plate 2, the movable plate 5 ensures that the component 11 maintains a stable and precise position during the welding process, thereby avoiding welding defects caused by position offset. Positioning shafts 6 are provided on both sides of the movable plate 5, and a quick-plugging mechanism 7 is provided in the middle of the positioning shaft 6. The positioning shaft 6 provides a stable support point for the movable plate 5, ensuring that the movable plate 5 does not shift during the welding process, thereby ensuring the safety and reliability of the operation. The quick-plugging mechanism 7 allows the operator to quickly plug in the movable plate 5 and the workpiece. The bolt 16 on the positioning shaft 6 can be quickly released by a simple pushing action, so that the horizontal positioning pin 4 on the component 11 can be quickly removed, so that the component 11 can be quickly replaced, which greatly improves production efficiency. A vertical positioning pin 8 is provided on one side of the receiving plate 2. The vertical positioning pin 8 and the horizontal positioning pin 4 together lock the component 11, so that the component 11 is firmly positioned in both the X and Y directions when placed on the receiving plate 2, ensuring the accuracy of welding. The setting position of the vertical positioning pin 8 should correspond to the hole position of the component 11. A control rib plate 9 is provided at the bottom of the receiving plate 2. The control rib plate 9 enhances the overall rigidity of the tooling, provides stable support for the workpiece, and reduces the risk of deformation caused by uneven force. A base plate 10 is provided at the bottom of the control rib plate 9. The base plate 10 is made of high-hardness metal material. The base plate 10 serves as the basic platform of the entire welding tooling, providing a stable support, ensuring that each component can be accurately positioned thereon, and maintaining the stability and reliability of the overall structure. Example 2

[0024] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 4 As shown, see the following description for details:

[0025] As a preferred embodiment, a component 11 is provided on one side of the reference plate 1, and the component 11 is fixed to the top of the receiving plate 2 by a horizontal positioning pin 4 and a vertical positioning pin 8. Furthermore, a three-dimensional positioning system formed by the horizontal positioning pin 4 and the vertical positioning pin 8 is used to accurately control the position of the component 11 from the horizontal X, Y axis and vertical Z axis directions to ensure the accuracy of each welding.

[0026] As a preferred embodiment, the control ribs 9 include height control ribs 12 and length control ribs 13. There are three groups of height control ribs 12, and the three groups of height control ribs 12 are evenly arranged obliquely along the top horizontal direction of the base plate 10. A length control rib 13 is arranged in the middle of the height control ribs 12. Furthermore, by arranging the three groups of height control ribs 12 obliquely and evenly, a stable support structure is formed, which effectively avoids the displacement or tilt of the workpiece during the welding process, thereby significantly improving the positioning accuracy of the welding. The layout of the height control ribs 12 and the close combination with the base plate 10 enhance the rigidity of the overall structure. The setting of the length control ribs 13 can adapt to workpieces of different lengths, providing more flexibility. The design of this length control rib 13 adopts a modular concept, which is convenient for rapid replacement and adjustment according to different welding tasks, thereby enhancing the adaptability and flexibility of the equipment.

[0027] As a preferred embodiment, a bolt bayonet 14 is provided on the outer wall of the positioning shaft 6. The bolt bayonet 14 is provided in several groups, and each group of bolt bayonet 14 is evenly arranged along the horizontal direction of the positioning shaft 6. Furthermore, the operator can quickly insert or remove the bolt 16 to achieve rapid clamping and disassembly of the workpiece. The design of multiple groups of bolt bayonet 14 allows the most suitable bayonet to be selected for positioning according to the size and shape of different workpieces. The design of the bolt bayonet 14 fully considers people's gestures and usage habits, making the insertion and removal actions natural and smooth, reducing the labor intensity of the operator.

[0028] As a preferred embodiment, the quick plug-in and pull-out mechanism 7 includes a base 15, a plug 16, a spring 17 and a push plate 18. Plugs 16 are provided in the two groups of hollow holes on the outer wall of the base 15. A spring 17 is provided on one side of the plug 16. The plug 16 is connected to the base 15 through the spring 17. A push plate 18 is provided on the other side of the plug 16. Furthermore, the main components are made of high-quality alloy steel or high-performance plastic to ensure the durability and reliability of the mechanism. When the push plate 18 is not subjected to force, the plug 16 is fully inserted into the hollow hole of the base 15 through the elastic force of the spring 17. At this time, the plug 16 is in a locked state and can achieve stable positioning. When the plug 16 needs to be pulled out, the operator pushes the push plate 18, and the push plate 18 transmits force to the plug 16, overcoming the elastic force of the spring 17, so that the plug 16 is partially or completely withdrawn from the hollow hole of the base 15 to achieve release.

[0029] As a preferred embodiment, the bolt 16 can compress the spring 17 through the push of the push plate 18, so that the bolt 16 is away from the positioning shaft 6, so that the movable plate 5 drives the three groups of horizontal positioning pins 4 to move horizontally along the positioning shaft 6. After the displacement stops, the push plate 18 is released so that the bolt 16 is connected to the positioning shaft 6 under the drive of the spring 17. Furthermore, the push plate 18 is designed to be easy to hold by hand so that it can smoothly transmit force to the bolt 16 when it is under force. During the connection process, it is necessary to ensure that the connection between the push plate 18 and the bolt 16 is not loose to ensure effective transmission of force. The movable plate 5 drives the horizontal displacement of the horizontal positioning pin 4 along the positioning shaft 6 to ensure the consistency and accuracy of each positioning of the workpiece.

[0030] The working process of the present invention is as follows: first, the drill head arm (component 11) to be welded is placed on the receiving plate 2, and the component 11 is preliminarily positioned by the transverse positioning pin 4 set on the reference plate 1. Once the component 11 is preliminarily positioned, the operator pushes the movable plate 5 toward the component 11. As the movable plate 5 is pushed forward, the transverse positioning pin 4 is inserted into the positioning hole of the component 11 to achieve fine positioning. After the movable plate 5 pushes the transverse positioning pin 4 to the final position, the quick plug-in mechanism 7 is started, and the operator pushes the push plate 18. This action transmits force through the plug 16, compresses the spring 17 and retracts the plug 16 to produce fixation. Then the welding equipment is started and the component 11 that has been fully positioned and locked is welded. After welding is completed, the operator operates the quick plug-in mechanism 7 again, pushes the push plate 18 and compresses the spring 17 to retract the plug 16, thereby releasing the transverse positioning pin 4 on the movable plate 5. As the positioning pin is released, the component 11 can be taken out. The above is the working principle of a welding tool that is convenient for removing components.
