[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 , which is the first embodiment of the present invention, provides a tooling structure for laser welding positioning. The core of the tooling structure design is to improve the operating accuracy and efficiency of laser welding while reducing the operating complexity. This embodiment is particularly suitable for laser welding operations that require high accuracy and high repeatability.

[0038] The positioning mechanism 100 is a core component, including a base 101, on the top of which a positioning plate 102 is movably installed. A positioning groove 102a is designed on the top of the positioning plate 102, and its main function is to accurately place the copper bar to ensure that the copper bar is fixed in position during the welding process, which is very important for improving the welding accuracy. Above the copper bar, a cover plate 103 is placed on the top of the positioning plate 102 to cover the brass sheet placed on the copper bar. Through the positioning component 104, the cover plate 103 is limited and fixed directly above the positioning plate 102, so that the cover plate 103 can be stably pressed on the top of the positioning plate 102, ensuring that the copper bar and the brass sheet can be firmly clamped in the positioning groove 102a.

[0039] Connecting grooves 101a are designed on the left and right sides of the top of the base 101 to accommodate and fix the connecting plates 105 at the bottom of the positioning plate 102. These connecting plates 105 are plugged into the connecting grooves 101a and the structural stability is enhanced by the internal card slots 105a. In addition, a weight-reducing hole 103a is designed in the middle of the cover plate 103 to further reduce the overall weight and improve the flexibility of the structure. The waist holes 103b symmetrically arranged on both sides of the weight-reducing hole are located directly above the positioning groove 102a, directly corresponding to the laser welding area.

[0040] The positioning assembly 104 includes an electric cylinder 104a fixedly mounted on the top of the base 101. The electric cylinder has a high degree of dynamic response capability and is used to accurately control the vertical pressure during the welding process. The output end of the electric cylinder 104a is movably connected to a telescopic rod 104b. The telescopic rod 104b has good mechanical strength and stable telescopic performance. Its length can be adjusted according to welding requirements, thereby adjusting the distance between the pressure plate 104c at its top and the cover plate 103. The pressure plate 104c is designed to evenly distribute the pressure from the electric cylinder. A pressure block 104d is fixedly connected to its bottom surface. The pressure block directly contacts the cover plate 103 to provide the necessary downward pressure to fix and stabilize the brass sheet. The bottom surface of the pressure block 104d is against the upper surface of the cover plate 103 to form a stable contact surface. The design of this mechanism can not only dynamically adjust the pressure, but also ensure the stability of the material and the maintenance of the precise position during the welding process.

[0041] The clamping mechanism 200 provides fixation and release of the connecting plate 105 through the design inside the base 101. The overall operation is very convenient and can be completed by operating the push rod 208 at the front end of the base 101. This design makes changing product specifications or adjusting welding settings fast and efficient, reducing the complexity of operation.

[0042] The newly developed tooling structure has strong compatibility. All product specifications and models share a set of bases 101. Different specifications and sizes only need to adjust the positioning plate 102 and the cover plate 103, which is convenient for switching models. This universal design greatly saves welding time and improves production efficiency. In response to the needs of reliable and convenient product welding switching, the design adopts plug-in positioning to facilitate tooling installation. The products have six widths. For products of different widths, the same base 101 can be shared. The products have three specifications of brass sheets, and three types of cover plates 103 are designed according to the specifications of the brass sheets. When switching products, only the positioning plate 102 and the cover plate 103 need to be removed, and the brass sheet cover plate of the corresponding specifications can be selected to complete the product switching, and finally the equipment welding can be started. This flexible design solves the problem of pre-welding required for manual laser welding, and at the same time, there is no need for manual work to ensure the welding accuracy. The accuracy of the tooling ensures the welding accuracy.

[0043] Example 2

[0044] Reference Figures 3 to 10 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment and further optimizes the design and function of the clamping mechanism 200. In this embodiment, the clamping mechanism 200 plays a key role. It is equipped with a push rod 208 that can be pressed twice, which enhances the flexibility and efficiency of the operation. The first operation of pressing the push rod 208 will drive the clamping plate 201 to be inserted into the clamping slot 105a. This action fixes the connecting plate 105 in the connecting slot 101a, thereby achieving a stable connection between the positioning plate 102 and the base 101, ensuring the positioning accuracy and stability during the welding process (such as Figure 2 , Figure 3 When pressed for the second time, the push rod 208 triggers the card plate 201 to move out of the card slot 105a, releasing the limit fixation of the connecting plate 105, so that the staff can easily remove the positioning plate 102 from the base 101 for replacement.

[0045] In addition, the push rod 208 is designed to automatically return to its initial state, that is, a state that can be pressed twice again. After the first press, the card plate 201 moves into the connecting groove 101a and is fixed; after the second press, all components return to the initial state, and the clamping end of the card plate 201 can also be moved out of the connecting groove 101a. When the positioning plate 102 is placed on the base 101 again, the staff only needs to press the push rod 208 once to enable the card plate 201 to re-clamp and fix the connecting plate 105, thereby quickly restoring the working state. This design not only improves work efficiency, but also increases the flexibility of the equipment, making replacement and maintenance more convenient and faster.

[0046] Specifically, the clamping mechanism 200 includes a clamping plate 201 inserted into the two clamping grooves 105a, and the opposite surfaces of the two clamping plates 201 are fixedly installed with movable plates 202, which are used to drive the clamping plates 201 to move horizontally when the connecting plate 105 needs to be fixed or released. The opposite surfaces of the two movable plates 202 are fixedly installed with tooth plates 203, and the two tooth plates 203 are arranged obliquely symmetrically up and down, and can achieve synchronous movement through the meshing connected annular teeth 204. A rotating cylinder 205 is fixedly installed on the inner side of the annular teeth 204, and a through hole 205a is opened inside the rotating cylinder 205. A slide groove 205b is provided on the inner wall of the hole 205a, and a slider 206 is slidably connected inside the slide groove 205b. The slide groove 205b has two parts, the first part is a spiral groove 205b1, and the second part is a straight groove 205b2, and the rear end of the spiral groove 205b1 is connected to the straight groove 205b2. The slider 206 slides in the slide groove, and one end is connected by a movable rod 207. The front end of the movable rod passes through the inner wall of the base 101 and extends to the outside, and is fixedly connected to a push rod 208 for manual operation. The rear end of the movable rod 207 is fixedly connected to a locking assembly 209.

[0047] A first cavity 101b is provided inside the base 101 and between the two connecting grooves 101a. The front and rear ends of the rotating drum 205 are rotatably connected to the front wall and the rear wall of the first cavity 101b respectively. The two movable plates 202 and the tooth plate 203 are also slidably connected in the first cavity 101b to achieve stable mechanical interaction. A second cavity 101c is provided inside the base 101 and directly behind the first cavity 101b. The rear end of the movable rod 207 passes through the first cavity 101b and extends to the second cavity 101c, and is fixedly connected to a first telescopic spring 210. The rear end of the first telescopic spring 210 is fixedly connected to the rear wall of the second cavity 101c, thereby achieving tension control of the movable rod.

[0048] The locking assembly 209 includes a fixed rod 209a fixedly mounted on the rear wall of the second cavity 101c, a first conical block 209b is fixedly connected to the front end of the fixed rod 209a, a second conical block 209c is arranged at the rear end of the first conical block 209b, and the second conical block 209c is slidably connected to the outer surface of the fixed rod 209a, the fixed rod 209a, the first conical block 209b and the second conical block 209c are all arranged on the inner side of the first telescopic spring 210, so as not to affect the normal telescopic extension of the first telescopic spring 210, there is a certain gap between the first conical block 209b and the second conical block 209c, and a magnet 209d is fixedly mounted on the rear end of the second conical block 209c, which is used to ensure that after the second conical block 209c is driven to the front end of the fixed rod 209a, in the absence of power, the magnetic attraction of the magnet 209d ensures that the second conical block 209c can return to its initial state.

[0049] A telescopic chamber 207a is provided at the rear end of the movable rod 207, and telescopic grooves 207b are symmetrically provided inside the telescopic chamber 207a. Second telescopic springs 211 are installed inside the two telescopic grooves. Wedge blocks 212 are fixedly connected to the opposite surfaces of the two second telescopic springs 211. The first conical block 209b is arranged in the telescopic chamber 207a, and the front right-angle surfaces of the two wedge blocks 212 are tightly pressed against the rear straight surface of the first conical block 209b to realize the limit control of the movable rod (such as Figure 4 shown).

[0050] A limiting groove 101d is provided inside the base 101 and at the front end of the first cavity 101b. The limiting groove 101d is internally slidably connected to a limiting plate 213. The limiting plate 213 is fixedly mounted on the outer surface of the movable rod 207 to limit the forward and backward movement range of the movable rod to ensure the accuracy and safety of the entire clamping and releasing operation. At the same time, the limiting plate 213 is rectangular, so that the movable rod 207 will not rotate.

[0051] The clamping mechanism 200 can be divided into two working states during use: the first state is a clamping state, and the second state is a releasing state.

[0052] The first state: card connection state

[0053] like Figures 3 to 10 As shown, when in the clamping state, the connecting plate 105 is inserted into the connecting groove 101a, and the clamping plate 201 is inserted into the clamping groove 105a, thereby realizing the limiting fixation of the connecting plate 105, so that the positioning plate 102 can be stably connected above the base 101. At this time, the first telescopic spring 210 is in a semi-compressed state, and the front end right-angle surfaces of the two wedge-shaped blocks 212 are against the rear end straight surface of the first conical block 209b, thereby preventing the rebound force of the first telescopic spring 210 from pushing the movable rod 207 to move forward, so that the movable rod remains in this position, ensuring the stability of the connection.

[0054] When the staff needs to remove the positioning plate 102, they only need to press the push rod 208, which pushes the movable rod 207 to move backward, and the slider 206 slides in the straight groove 205b2 of the slide groove 205b. The rotating cylinder 205 remains stationary. As the movable rod 207 moves backward, the first telescopic spring 210 is further compressed. At the same time, the wedge-shaped block 212 in the telescopic cavity 207a approaches the second conical block 209c. When the wedge-shaped block 212 and the second conical block When the first conical block 209c contacts the second conical block 209c, the wedge block 212 is squeezed into the telescopic slot 207b, and the movable rod 207 continues to move backward until the limiting plate 213 abuts against the rear wall of the limiting slot 101d, and the wedge block 212 moves to the rear end of the second conical block 209c. Under the rebound force of the second telescopic spring 211, the two wedge blocks 212 can clamp the second conical block 209c. At this time, since the first conical block 209b is no longer blocked, the first telescopic spring 210 The rebound force can push the movable rod 207 to move forward. During the process of the movable rod 207 moving forward, the wedge block 212 will clamp the second conical block 209c and move forward together until the front end of the second conical block 209c abuts against the rear end of the first conical block 209b. At this time, the second conical block 209c is fixed at this position and cannot move forward, while the movable rod 207 continues to move forward under the thrust of the first telescopic spring 210, causing the wedge block 212 to move along the second conical block 209c. The inclined surface at the rear side of 9c is gradually squeezed into the telescopic groove 207b. When the two wedge blocks 212 are separated from the inclined surface at the rear side of the second conical block 209c, they can quickly pass through the second conical block 209c and the first conical block 209b, and completely separate from the locking assembly 209. The movable rod 207, the slider 206, the limit plate 213 and the push rod 208 all return to their initial positions. The slider 206 moves along the straight groove 205b2 and finally enters the spiral groove 205b1.

[0055] When the slider 206 moves from the straight groove 205b2 to the spiral groove 205b1, due to the lateral limiting effect of the limiting plate 213 and the limiting groove 101d, the movable rod 207 and the slider 206 keep moving forward in a straight line. In this process, the lateral cutting force of the slider 206 and the spiral groove 205b1 causes the rotating drum 205 to rotate, thereby driving the annular gear 204 and the upper and lower tooth plates 203 to move in opposite directions. The upper tooth plate 203 moves to the right, and the lower tooth plate 203 moves to the left. The two tooth plates 203 drive the clamping plate 201 to move horizontally toward each other through the moving plate 202. Finally, the clamping plate 201 moves out of the connecting groove 101a and the clamping groove 105a, releasing the limiting fixation of the connecting plate 105, so that the positioning plate 102 can be removed.

[0056] The second state: Unfixed state

[0057] When in the unfixed state, the clamping end of the clamping plate 201 moves out from the connecting groove 101a, and part of the clamping plate 201 enters the first cavity 101b. The right side of the upper tooth plate 203 abuts against the right movable plate 202, and the left side of the lower tooth plate 203 abuts against the left movable plate 202. At this time, the rear end of the movable rod 207 and the locking assembly 209 are in a separated state, the limit plate 213 moves to the front end of the limit groove 101d, most of the push rod 208 is exposed outside the base 101, and the first telescopic spring 210 is in a fully extended state.

[0058] When the fixing is released, the staff can place the new positioning plate 102 on the base 101, and the two connecting plates 105 at the bottom of the positioning plate 102 can be smoothly inserted into the connecting groove 101a. At this time, the staff only needs to press the push rod 208, and the push rod 208 drives the movable rod 207 to move backward, and the slider 206 moves in the spiral groove 205b1. The lateral cutting force causes the rotating drum 205 to rotate, and the rotation of the rotating drum 205 drives the annular gear 204 to rotate, thereby driving the upper tooth plate 203 to move horizontally to the left, and the lower tooth plate 203 to move horizontally to the right. The two tooth plates 203 drive the movable plate 202 and the card plate 201 to move toward each other, and the card end of the card plate 201 moves into the connecting groove 101a, and finally completely passes through the card groove 105a of the connecting plate 105, thereby realizing the limit fixation of the connecting plate 105 and completing the installation of the positioning plate 102.

[0059] When the slider 206 continues to move to the intersection of the spiral groove 205b1 and the straight groove 205b2, the two wedge-shaped blocks 212 in the telescopic cavity 207a at the rear end of the movable rod 207 begin to contact with the first conical block 209b. This abutment process can be described in detail as follows: when the movable rod 207 moves backward, the first conical block 209b gradually extends into the telescopic cavity 207a and abuts against the rear wall of the wedge-shaped block 212. Since the front end of the first conical block 209b is designed as an inclined surface, As the rod 207 continues to move backward, the wedge blocks 212 are gradually squeezed into their respective telescopic grooves 207b, which causes the two second telescopic springs 211 to be compressed accordingly. When the two wedge blocks 212 at the rear end of the movable rod 207 move to the rear end of the first conical block 209b, without the obstruction of the inclined surface of the first conical block 209b, the two wedge blocks 212 are ejected to abut against each other under the action of the rebound force of the second telescopic spring 211, and tightly against the rear end of the first conical block 209b. This state of abutment keeps the movable rod 207 in a fixed position, and the rebound force of the first telescopic spring 210 cannot push the movable rod 207 forward, forming a locking effect to ensure the stability of the movable rod 207.

[0060] In this state, the clamping end of the clamping plate 201 completely passes through the clamping groove 105a of the connecting plate 105, thereby achieving the limiting fixation of the connecting plate 105, thereby completing the installation of the positioning plate 102 and ensuring its stable connection with the base 101. At the same time, the locking assembly 209 plays a key role at the rear end of the movable rod 207. Through the cooperation of the first conical block 209b and the wedge block 212, the locking state of the movable rod 207 can be achieved, thereby ensuring the firmness and reliability of the entire tooling structure during the working process.

[0061] Through this locking mechanism, the movable rod 207 can achieve precise and stable locking and unlocking after pressing the push rod 208, ensuring the repeatability and reliability of each operation and reducing the impact of human factors on the installation quality of the workpiece. This process not only makes the installation of the positioning plate 102 more convenient, but also greatly improves the equipment stability and process accuracy during the welding process.
