[0064] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0065] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0066] The tooling fixture 200 of the embodiment of the present utility model will be described below with reference to the accompanying drawings of the specification.

[0067] Combined as Figure 1 and Figure 2 shown, the tooling fixture 200 according to the embodiment of the present utility model includes: a support base 900 and a pressing device 210.

[0068] Among them, combined with Figure 1 , Figure 2 and Figure 3 shown, the support base 900 has a support plane 910 suitable for supporting the workpiece to be welded 2000. Here, it means that the support base 900 is provided with a support plane 910, and the support plane 910 is used to support the workpiece to be welded 2000, so as to place the workpiece to be welded 2000 on the support base 900, thereby facilitating the use of the support base 900 to support the workpiece to be welded 2000, improving the position stability of the workpiece to be welded 2000, facilitating the use of a welding tool to weld the workpiece to be welded 2000, reducing the welding difficulty, and improving the welding quality.

[0069] In some embodiments, the workpiece to be welded 2000 is a battery tray.

[0070] Combined with Figure 1 and Figure 2 shown, the pressing device 210 includes a plurality of first pressing mechanisms 211. The plurality of first pressing mechanisms 211 surround the outer periphery of the workpiece to be welded 2000. The first pressing mechanism 211 includes a first driving member 2111 and a first pressing arm 2112. The first driving member 2111 is arranged on the support base 900. The axis of the first driving member 2111 is parallel to the support plane 910. The first pressing arm 2112 is connected to the first driving member 2111. The first driving member 2111 is used to drive the first pressing arm 2112 to rotate relative to the support base 900 to press or release the workpiece to be welded 2000.

[0071] That is to say, the first driving member 2111 and the first pressing arm 2112 cooperate to enable the first pressing mechanism 211 to press or release the workpiece to be welded 2000. When the first pressing mechanism 211 presses the workpiece to be welded 2000, the workpiece to be welded 2000 can be stably arranged on the support seat 900, so as to improve the position stability of the workpiece to be welded 2000, and to a certain extent, avoid displacement of the workpiece to be welded 2000 when the welding tool welds the workpiece to be welded 2000, thereby reducing the welding difficulty and improving the welding quality. When the first pressing mechanism 211 releases the workpiece to be welded 2000, on the one hand, it is convenient to take out the welded workpiece to be welded 2000, and on the other hand, it can adjust the position of the first pressing arm 2112 relative to the workpiece to be welded 2000, so that the first pressing arm 2112 is arranged away from the workpiece to be welded 2000, thus avoiding interference between the first pressing arm 2112 and the welding tool to a certain extent, that is, avoiding the first pressing arm 2112 from hindering the welding of the welding tool to a certain extent, further reducing the welding difficulty of the workpiece to be welded 2000 and improving the welding quality.

[0072] It should be noted that during the actual welding process of the welding tool, when the first pressing arm 2112 presses the workpiece to be welded 2000 but the first pressing arm 2112 interferes with the welding tool, the first driving member 2111 drives the first pressing arm 2112 to rotate relative to the support seat 900 to release the workpiece to be welded 2000, so as to avoid the welding tool, and to a certain extent, avoid the first pressing arm 2112 from hindering the welding of the welding tool. When there is no interference, then control the first pressing arm 2112 to rotate relative to the support seat 900 and press the workpiece to be welded 2000 to achieve the purpose of fixing the workpiece to be welded 2000.

[0073] That is to say, the first pressing arm 2112 opens to avoid the welding tool when the welding tool passes by, and closes to press the workpiece to be welded 2000 after the welding tool passes by.

[0074] It is worth noting that this application is provided with a plurality of first pressing mechanisms 211, and the plurality of first pressing mechanisms 211 are arranged to surround the outer periphery of the workpiece to be welded 2000. On the one hand, it can realize the cooperation of the plurality of first pressing mechanisms 211 to press the workpiece to be welded 2000 at the same time, improving the position stability of the workpiece to be welded 2000. On the other hand, when one of the first pressing arms 2112 opens when the welding tool passes by, the remaining first pressing arms 2112 can be used to press the workpiece to be welded 2000, avoiding the reduction of the fixing strength of the workpiece to be welded 2000 due to the opening of one of the first pressing arms 2112.

[0075] It is also worth noting that since the first pressing arm 2112 needs to be opened when the welding tool passes by and then closed after the welding tool passes by, based on this, the axis of the first driving member 2111 in this application is set to be parallel to the support plane 910, that is, the first driving member 2111 is set as a horizontal driving member. In this way, the height of the first driving member 2111 can be reduced, thereby reducing the overall height of the first pressing mechanism 211. On the one hand, it can avoid increasing the overall height dimension of the tooling fixture 200 due to the setting of the first pressing mechanism 211 and reduce the assembly difficulty of the tooling fixture 200. On the other hand, when the first driving member 2111 drives the first pressing arm 2112 to open to release the workpiece to be welded 2000, the overall height of the first pressing arm 2112 can be reduced. At this time, the first pressing arm 2112 can rotate a smaller angle to avoid the welding tool, thereby avoiding interference between the first pressing arm 2112 and the welding tool when the first pressing arm 2112 releases the workpiece to be welded 2000 to a certain extent, reducing the welding difficulty, and reducing the control difficulty of the first pressing arm 2112.

[0076] Among them, the height mentioned here can be understood as the dimension of the first pressing mechanism 211 in the Figure 1 Z direction shown in the figure, that is, the vertical dimension of the first pressing mechanism 211. During the welding process of the workpiece to be welded 2000, the first pressing arm 2112 presses on the upper surface of the workpiece to be welded 2000 in the Z direction, and the welding tool is located on the upper surface of the workpiece to be welded 2000.

[0077] That is to say, the axis of the first driving member 2111 in this application is set to be parallel to the support plane 910. While facilitating the reduction of the overall height dimension of the tooling fixture 200, it can also avoid interference between the first pressing arm 2112 and the welding tool when the first pressing arm 2112 opens to release the workpiece to be welded 2000 to a certain extent, reduce the welding difficulty, and reduce the control difficulty of the first pressing arm 2112.

[0078] In some embodiments, as shown in combination with Figure 1 and Figure 2 , the axis of the first driving member 2111 extends along the X direction or the Y direction, and the support plane 910 is parallel to the X direction and the Y direction, so that the axis of the first driving member 2111 is parallel to the support plane 910.

[0079] In addition, by arranging the first driving member 2111 on the support seat 900, the support seat 900 can be used to support the first driving member 2111, improve the position stability of the first driving member 2111, thereby ensuring the working performance of the first driving member 2111 to a certain extent and reducing the fixing difficulty of the first driving member 2111.

[0080] As can be seen from the above structure, the tooling fixture 200 of the embodiment of the present utility model can realize the simultaneous pressing of the workpiece to be welded 2000 by multiple first pressing mechanisms 211 through the setting of the pressing device 210 and arranging the pressing device 210 to include a plurality of first pressing mechanisms 211 surrounding the outer periphery of the workpiece to be welded 2000, improve the position stability of the workpiece to be welded 2000, thereby reducing the welding difficulty of the workpiece to be welded 2000 and improving the welding quality.

[0081] At the same time, the axis of the first driving member 2111 of the first pressing mechanism 211 is set to be parallel to the supporting plane 910, so that the first driving member 2111 is formed into a horizontal driving member, thereby realizing the reduction of the height of the first driving member 2111, that is, reducing the overall height of the first pressing mechanism 211. On the one hand, it avoids increasing the overall height dimension of the tooling fixture 200 due to the setting of the first pressing mechanism 211 and reduces the assembly difficulty of the tooling fixture 200. On the other hand, when the first driving member 2111 drives the first pressing arm 2112 to open to release the workpiece to be welded 2000, the overall height of the first pressing arm 2112 is reduced, so that the first pressing arm 2112 can rotate a smaller angle to avoid the welding tool, to a certain extent, avoiding interference between the first pressing arm 2112 and the welding tool when the first pressing arm 2112 releases the workpiece to be welded 2000, reducing the welding difficulty and reducing the control difficulty of the first pressing arm 2112.

[0082] That is to say, the tooling fixture 200 of the present application can not only press the workpiece to be welded 2000, but also effectively avoid the welding tool.

[0083] It can be understood that compared with the prior art, the present application arranges a plurality of first pressing mechanisms 211 surrounding the outer periphery of the workpiece to be welded 2000 and sets the axis of the first driving member 2111 of the first pressing mechanism 211 to be parallel to the supporting plane 910. While realizing the pressing of the workpiece to be welded 2000 by the cooperation of multiple first pressing mechanisms 211, it can also make the multiple first pressing mechanisms 211 rotate a smaller angle to effectively avoid the welding tool, reduce the control difficulty of the first pressing arm 2112, to a certain extent, avoid the pressing member 120 from hindering the welding of the welding tool, reduce the welding difficulty of the workpiece to be welded 2000, and improve the welding quality.

[0084] In some embodiments, the first driving member 2111 is a driving oil cylinder. The driving oil cylinder has significant advantages such as high efficiency, flexibility, reliability and strong bearing capacity, so that the first driving member 2111 can effectively drive the first pressing arm 2112 to rotate relative to the supporting seat 900, to a certain extent, ensuring the working performance of the first pressing mechanism 211.

[0085] Of course, in some other embodiments, the first driving member 2111 can also be a driving air cylinder.

[0086] In some embodiments, in combination with Figure 2 , Figure 4 and Figure 6 as shown, the first pressing mechanism 211 further includes a first pressing block 2113. The first pressing block 2113 is disposed at the pressing end of the first pressing arm 2112 and is arranged towards the workpiece to be welded 2000, facilitating the use of the first pressing block 2113 to press the workpiece to be welded 2000. While achieving the pressing and fixing of the workpiece to be welded 2000, the contact area between the first pressing arm 2112 and the workpiece to be welded 2000 can also be reduced, thereby avoiding the first pressing arm 2112 from damaging the workpiece to be welded 2000 to a certain extent.

[0087] Optionally, the first pressing block 2113 is made of materials such as copper and aluminum.

[0088] In some embodiments, in combination with Figure 1 , Figure 2 and Figure 4 as shown, a plurality of first pressing mechanisms 211 include a first pressing assembly 212. The first driving member 2111 of the first pressing assembly 212 has a first output end 2121. The first output end 2121 is located on the side of the first driving member 2111 of the first pressing assembly 212 facing the workpiece to be welded 2000. The first pressing arm 2112 of the first pressing assembly 212 is rotatably connected to the first output end 2121. Here, it means that the axis of the first driving member 2111 is parallel to the support plane 910, and the first output end 2121 of the first driving member 2111 of the first pressing assembly 212 extends towards the workpiece to be welded 2000, so that the first output end 2121 is arranged close to the workpiece to be welded 2000. In this way, when the first pressing arm 2112 of the first pressing assembly 212 is rotatably connected to the first output end 2121, the first pressing arm 2112 of the first pressing assembly 212 can be arranged close to the workpiece to be welded 2000, facilitating the use of the first pressing arm 2112 of the first pressing assembly 212 to press the workpiece to be welded 2000 and reducing the fixing difficulty of the workpiece to be welded 2000.

[0089] Meanwhile, through the above arrangement, when the first pressing arm 2112 rotates relative to the support base 900 and releases the workpiece to be welded 2000, the rotation angle of the first pressing mechanism 211 is small, and the overall height of the first pressing mechanism 211 is relatively low, effectively avoiding the welding tool and preventing the first pressing mechanism 211 from interfering with the welding tool, thereby facilitating the use of the welding tool to weld the workpiece to be welded 2000 and reducing the welding difficulty.

[0090] In addition, through the above settings, the first driving member 2111 of the first pressing assembly 212 can be arranged away from the first pressing arm 2112 of the first pressing assembly 212 with respect to the workpiece to be welded 2000, so that the first driving member 2111 of the first pressing assembly 212 can avoid the structure on the workpiece to be welded 2000, thereby enabling the first driving member 2111 of the first pressing assembly 212 to be effectively arranged on the support base 900, facilitating the use of the first pressing arm 2112 of the first pressing assembly 212 to press the workpiece to be welded 2000.

[0091] In some embodiments, as Figure 4 and Figure 5 shown, the first pressing assembly 212 further includes a first transfer shaft 2126. The first output end 2121 is rotationally connected to the first pressing arm 2112 of the first pressing assembly 212 through the first transfer shaft 2126, thereby realizing the rotational connection between the first driving member 2111 of the first pressing assembly 212 and the first pressing arm 2112 of the first pressing assembly 212, and reducing the difficulty of the rotational connection between the first driving member 2111 of the first pressing assembly 212 and the first pressing arm 2112 of the first pressing assembly 212. This facilitates the use of the first driving member 2111 of the first pressing assembly 212 to drive the first pressing arm 2112 of the first pressing assembly 212 to rotate relative to the support base 900, so as to achieve the purpose of using the first pressing arm 2112 of the first pressing assembly 212 to press or release the workpiece to be welded 2000, and to a certain extent, ensure the working performance of the first pressing assembly 212.

[0092] For the convenience of description, hereinafter, the first driving member 2111 of the first pressing assembly 212 is defined as the first driving oil cylinder, and the first pressing arm 2112 of the first pressing assembly 212 is defined as the first pressing arm.

[0093] In summary, the axis of the first driving oil cylinder is parallel to the support plane 910. The first driving oil cylinder has a first output end 2121, and the first output end 2121 is located on the side of the first driving oil cylinder facing the workpiece to be welded 2000. The first pressing arm is rotationally connected to the first output end 2121.

[0094] In some embodiments, in combination with Figure 2 、 Figure 4 and Figure 5As shown, the first pressing assembly 212 includes a first mounting seat 2122. The first mounting seat 2122 is provided on the support seat 900. The first driving member 2111 and the first pressing arm 2112 of the first pressing assembly 212 are both rotatably connected to the first mounting seat 2122. Here, it means that the first driving oil cylinder and the first pressing arm are both rotatably connected to the first mounting seat 2122, so that the first driving oil cylinder and the first pressing arm can both rotate relative to the first mounting seat 2122, thereby facilitating the use of the first driving oil cylinder to drive the first pressing arm to rotate relative to the support seat 900, achieving the purpose of using the first pressing assembly 212 to press or release the workpiece to be welded 2000.

[0095] Among them, by providing the first mounting seat 2122 on the support seat 900 and rotatably connecting the first driving oil cylinder to the first mounting seat 2122, the first driving oil cylinder is installed on the support seat 900 by using the first mounting seat 2122, reducing the installation difficulty of the first driving oil cylinder, facilitating the use of the support seat 900 to support the first driving oil cylinder, and improving the position stability of the first driving oil cylinder.

[0096] In some embodiments, the first mounting seat 2122 is fixedly connected to the support seat 900 to achieve the fixed connection between the first driving oil cylinder and the support seat 900, improving the connection strength between the first driving oil cylinder and the support seat 900, thereby improving the position stability of the first driving oil cylinder.

[0097] Among them, the fixed connection between the first mounting seat 2122 and the support seat 900 mentioned here can be welding, bonding or bolt connection, etc.

[0098] In some embodiments, as Figure 4 and Figure 5 shown, the first mounting seat 2122 includes a driving member mounting seat 2123 and a pressing arm mounting seat 2124. One end of the first pressing arm is rotatably connected to the pressing arm mounting seat 2124, and the other end of the first pressing arm extends toward the workpiece to be welded 2000. One end of the first driving oil cylinder is rotatably connected to the middle section of the first pressing arm through the first output end 2121, and the other end of the first driving oil cylinder is rotatably connected to the driving member mounting seat 2123. At least part of the first driving oil cylinder is spaced from the driving member mounting seat 2123, thereby realizing that both the first driving oil cylinder and the first pressing arm are set to be rotatably connected to the first mounting seat 2122, ensuring the working performance of the first pressing assembly 212 to a certain extent.

[0099] Through the above settings, in a specific embodiment, when the first driving oil cylinder drives the first pressing arm to rotate relative to the support seat 900, the first driving oil cylinder itself rotates relative to the driving member mounting seat 2123, so that the first driving oil cylinder can effectively drive the first pressing arm to rotate, ensuring the working performance of the first pressing assembly 212 to a certain extent.

[0100] Specifically, when the other end of the first driving oil cylinder is rotatably connected to the driving member mounting seat 2123, the connection point between the other end of the first driving oil cylinder and the driving member mounting seat 2123 forms the rotation point of the first driving oil cylinder. When the first driving oil cylinder drives the first pressing arm to press the workpiece to be welded 2000, the output end of the first driving oil cylinder moves towards the first pressing arm to push the first pressing arm to rotate clockwise around the pressing arm mounting seat 2124. At the same time, the first driving oil cylinder rotates clockwise through the rotation point of the first driving oil cylinder to press the workpiece to be welded 2000 by using the first pressing assembly 212; when the first driving oil cylinder drives the first pressing arm to release the workpiece to be welded 2000, the output end of the first driving oil cylinder moves away from the first pressing arm to pull the first pressing arm to rotate counterclockwise around the pressing arm mounting seat 2124. At the same time, the first driving oil cylinder rotates counterclockwise through the rotation point of the first driving oil cylinder to release the workpiece to be welded 2000 by using the first pressing assembly 212.

[0101] Optionally, as Figure 4 and Figure 5 shown, the driving member mounting seat 2123 and the pressing arm mounting seat 2124 are spaced apart to form an avoidance space for avoiding the first pressing arm between the driving member mounting seat 2123 and the pressing arm mounting seat 2124, so that the first pressing arm can effectively rotate relative to the pressing arm mounting seat 2124.

[0102] In some embodiments, as Figure 4 and Figure 5 shown, the first pressing assembly 212 further includes a first adapter 2125. The first adapter 2125 is sleeved on the other end of the first driving oil cylinder and is rotatably connected to the driving member mounting seat 2123, thereby realizing the rotational connection between the other end of the first driving oil cylinder and the driving member mounting seat 2123 and reducing the rotational connection difficulty between the first driving oil cylinder and the driving member mounting seat 2123.

[0103] In some embodiments, in combination with Figure 1 , Figure 2 , Figure 6 and Figure 7As shown in the figure, a plurality of first pressing mechanisms 211 include a second pressing assembly 213. The first driving member 2111 of the second pressing assembly 213 has a second output end 2131. The second output end 2131 is located on the side of the first driving member 2111 of the second pressing assembly 213 facing away from the workpiece to be welded 2000. One end of the first pressing arm 2112 of the second pressing assembly 213 is rotatably connected to the second output end 2131, and the other end of the first pressing arm 2112 of the second pressing assembly 213 extends in the direction close to the workpiece to be welded 2000. Thus, the first pressing arm 2112 of the second pressing assembly 213 can be arranged close to the workpiece to be welded 2000, which is convenient for pressing the workpiece to be welded 2000 by the first pressing arm 2112 of the second pressing assembly 213 and reduces the difficulty of fixing the workpiece to be welded 2000.

[0104] For the convenience of description, hereinafter, the first driving member 2111 of the second pressing assembly 213 is defined as the second driving oil cylinder, and the first pressing arm 2112 of the second pressing assembly 213 is defined as the second pressing arm.

[0105] That is to say, the axis of the second driving oil cylinder is parallel to the support plane 910. The second driving oil cylinder has a second output end 2131. The second output end 2131 is located on the side of the second driving oil cylinder facing away from the workpiece to be welded 2000. One end of the second pressing arm is rotatably connected to the second output end 2131, and the other end of the second pressing arm extends in the direction close to the workpiece to be welded 2000.

[0106] It should be emphasized that by setting the second output end 2131 on the side of the second driving oil cylinder facing away from the workpiece to be welded 2000, when the second driving oil cylinder controls the second pressing arm to open through the second output end 2131 to release the workpiece to be welded 2000, it is convenient to control the second pressing arm to rotate a large angle, reduce the rotation difficulty of the second pressing arm, so that the second pressing arm can effectively avoid the welding tool to prevent interference between the second pressing arm and the welding tool.

[0107] At the same time, because the rotation difficulty of the second pressing arm is reduced, the extension length of the second pressing arm can be adaptively increased, so that the inner structure of the workpiece to be welded 2000 can be pressed by the second pressing arm, further ensuring the working performance of the second pressing arm and being beneficial to improving the pressing quality of the first pressing mechanism 211.

[0108] Optionally, in combination with Figure 2 、 Figure 6 and Figure 7As shown, an accommodation space 2132 for accommodating the workpiece to be welded 2000 is formed between the first driving member 2111 and the first pressing arm 2112 of the second pressing assembly 213. Here, it means that the second output end 2131 is arranged on the side of the second driving oil cylinder facing away from the workpiece to be welded 2000, and one end of the second pressing arm is rotatably connected to the second output end 2131 and the other end of the second pressing arm extends towards the workpiece to be welded 2000. Then, an accommodation space 2132 for accommodating the workpiece to be welded 2000 is formed between the second driving oil cylinder and the second pressing arm. On the one hand, the accommodation space 2132 is used to avoid the second pressing arm, so that the second pressing arm can effectively rotate to press or release the workpiece to be welded 2000. On the other hand, during the assembly process of the second pressing assembly 213, the second pressing assembly 213 can be arranged close to the workpiece to be welded 2000 through the accommodation space 2132, so as to avoid increasing the size of the tooling fixture 200 too much due to the setting of the second pressing assembly 213 to a certain extent, reduce the occupied space of the tooling fixture 200, and reduce the assembly difficulty of the tooling fixture 200.

[0109] In a specific example, in combination with Figure 2 、 Figure 3 、 Figure 6 and Figure 7 As shown, the second pressing assembly 213 is arranged in the support plane 910. After the workpiece to be welded 2000 is fixed in place, at least part of the workpiece to be welded 2000 is located in the accommodation space 2132, so that at least part of the second driving oil cylinder is located below the workpiece to be welded 2000 and at least part of the second pressing arm is located above the workpiece to be welded 2000. While facilitating the pressing of the workpiece to be welded 2000 by the second pressing arm, it can also avoid increasing the size of the tooling fixture 200 in the length direction and / or width direction too much due to the setting of the second pressing assembly 213.

[0110] Among them, the length direction mentioned here can be understood as the Figure 1 X direction shown in Figure 1 , and the width direction can be understood as the Figure 1 Y direction shown in

[0111] In summary, the multiple first pressing mechanisms 211 of the present application include a first pressing assembly 212 and a second pressing assembly 213. The first driving members 2111 of the first pressing assembly 212 and the second pressing assembly 213 are both formed as horizontal driving members. The first output end 2121 of the first pressing assembly 212 is located on the side of the first driving member 2111 of the first pressing assembly 212 facing the workpiece to be welded 2000, so that the first pressing assembly 212 can effectively avoid the structure on the workpiece to be welded 2000. The second output end 2131 of the second pressing assembly 213 is located on the side of the first driving member 2111 of the second pressing assembly 213 facing away from the workpiece to be welded 2000, so that the second pressing assembly 213 can accommodate a part of the structure of the workpiece to be welded 2000.

[0112] Through the above settings, during the assembly process of the first pressing mechanism 211, the installation positions of the first pressing assembly 212 and the second pressing assembly 213 can be selected according to the structure of the workpiece to be welded 2000. While ensuring the pressing effect of the first pressing mechanism 211, the flexibility of use of the first pressing mechanism 211 can also be improved.

[0113] Specifically, when the workpiece to be welded 2000 is formed as a battery tray, a cooling channel will be provided inside the battery tray, and a coolant inlet communicating with the cooling channel will be provided below the battery tray. The coolant inlet protrudes downward. In order to avoid interference between the first driving member 2111 of the first pressing mechanism 211 and the protruding coolant inlet or the structural member supporting the coolant inlet, the first pressing assembly 212 can be provided at the position corresponding to the coolant inlet, so that the first driving member 2111 of the first pressing assembly 212 can be set away from the workpiece to be welded 2000; correspondingly, the second pressing assembly 213 can be provided at the position not corresponding to the coolant inlet, and the workpiece to be welded 2000 is pressed by the second pressing assembly 213, which can not only reduce the size of the fixture 200, but also ensure the pressing quality and reduce the pressing difficulty.

[0114] In some embodiments, as shown in Figure 2 、 Figure 6 and Figure 7 The second pressing assembly 213 further includes a second mounting seat 2134. The second mounting seat 2134 is provided on the support seat 900, and the second driving oil cylinder is fixedly connected to the second mounting seat 2134. Thereby, the second driving oil cylinder is fixedly connected to the support seat 900, the connection difficulty between the second driving oil cylinder and the support seat 900 is reduced, so that it is convenient to use the support seat 900 to support the second driving oil cylinder, improve the position stability of the second driving oil cylinder, and ensure the working performance of the second driving oil cylinder.

[0115] Among them, the fixed connection here can be welding, bonding or bolt connection, etc.

[0116] In some embodiments, in combination with Figure 6 , Figure 7 and Figure 8 As shown, the second pressing assembly 213 further includes a second transfer shaft 2135 and a second transfer member 2137. One end of the first pressing arm 2112 of the second pressing assembly 213 is rotatably connected to the second output end 2131 through the second transfer shaft 2135, and the middle section of the first pressing arm 2112 of the second pressing assembly 213 is also rotatably connected to the first driving member 2111 of the second pressing assembly 213 through the second transfer member 2137, so as to realize the rotational connection between the first driving member 2111 of the second pressing assembly 213 and the first pressing arm 2112 of the second pressing assembly 213, and reduce the difficulty of the rotational connection between the first driving member 2111 of the second pressing assembly 213 and the first pressing arm 2112 of the second pressing assembly 213, facilitating the use of the first driving member 2111 of the second pressing assembly 213 to drive the first pressing arm 2112 of the second pressing assembly 213 to rotate relative to the support base 900, so as to achieve the purpose of using the second pressing assembly 213 to press or release the workpiece to be welded 2000, and to a certain extent ensure the working performance of the second pressing assembly 213.

[0117] In some embodiments, in combination with Figure 1 and Figure 2 As shown, both the first pressing assembly 212 and the second pressing assembly 213 include a plurality of them. The cooperation of the plurality of first pressing assemblies 212 and the plurality of second pressing assemblies 213 can effectively improve the pressing effect of the pressing device 210, thereby improving the position stability of the workpiece to be welded 2000.

[0118] In some embodiments, in combination with Figure 6 , Figure 7 and Figure 8 As shown, the second pressing assembly 213 further includes a limiting member 2133. The limiting member 2133 is arranged in the accommodating space 2132, and the limiting member 2133 is used for abutting and cooperating with the first pressing arm 2112 of the second pressing assembly 213 to limit the rotation angle of the first pressing arm 2112 of the second pressing assembly 213 towards the workpiece to be welded 2000. Since the first pressing arm 2112 of the second pressing assembly 213 of the present application has a relatively large rotation angle, by setting the limiting member 2133, while realizing the use of the first pressing arm 2112 of the second pressing assembly 213 to press the workpiece to be welded 2000, it can also, to a certain extent, prevent the first pressing arm 2112 of the second pressing assembly 213 from damaging the workpiece to be welded 2000 and ensure the service life of the workpiece to be welded 2000.

[0119] Among them, the limiting member 2133 mentioned here can be made of materials such as steel, aluminum, and copper to ensure that the limiting member 2133 has a certain structural strength, thereby ensuring the limiting effect of the limiting member 2133.

[0120] In some embodiments, in combination with Figure 6 、 Figure 7 and Figure 8 As shown, the second pressing assembly 213 further includes a support member 2136. The support member 2136 is disposed in the accommodation space 2132 and fixedly connected to the second driving oil cylinder. The limiting member 2133 is provided on the support member 2136 to support the limiting member 2133 by means of the support member 2136, improve the position stability of the limiting member 2133, and thus ensure the limiting effect of the limiting member 2133.

[0121] In some embodiments, in combination with Figure 1 and Figure 2 As shown, the tooling fixture 200 further includes a pressing plate 220. The pressing plate 220 is pressed against the side of the workpiece to be welded 2000 away from the support seat 900. The first pressing assembly 212 is used to press the pressing plate 220, and the second pressing assembly 213 is used to press the pressing plate 220 or the workpiece to be welded 2000. Here, it means that the second pressing assembly 213 can press the pressing plate 220 or the workpiece to be welded 2000. In this way, when there are multiple second pressing assemblies 213, multiple second pressing assemblies 213 can be used in cooperation to press the pressing plate 220 and the workpiece to be welded 2000 respectively, so as to achieve the purpose of pressing the workpiece to be welded 2000, improve the position stability of the workpiece to be welded 2000, and ensure the welding effect.

[0122] In addition, by providing the pressing plate 220, setting the first pressing assembly 212 to press the pressing plate 220, and setting the second pressing assembly 213 to press the pressing plate 220 or the workpiece to be welded 2000, it is possible to avoid the first pressing mechanism 211 from damaging the workpiece to be welded 2000 to a certain extent.

[0123] In some embodiments, the extension length of the first pressing arm 2112 of the second pressing assembly 213 can be adjusted to control the second pressing assembly 213 to press the pressing plate 220 or the workpiece to be welded 2000.

[0124] In some embodiments, as Figure 9 shown, a rubber pad 221 is provided on the side of the pressing plate 220 facing the workpiece to be welded 2000. In this way, when the workpiece to be welded 2000 is fixed on the support seat 900 by using the pressing plate 220, it is possible to provide the rubber pad 221 between the pressing plate 220 and the workpiece to be welded 2000, and to avoid the pressing plate 220 from damaging the workpiece to be welded 2000 to a certain extent.

[0125] In some embodiments, in combination with Figure 1 and Figure 2As shown, the pressing device 210 further includes a plurality of second pressing mechanisms 214. The plurality of second pressing mechanisms 214 surround the outer periphery of the workpiece to be welded 2000, and the second pressing mechanism 214 is used to press or release the workpiece to be welded 2000, so as to further improve the position stability of the workpiece to be welded 2000 and ensure the welding effect.

[0126] Among them, when the second pressing mechanism 214 presses the workpiece to be welded 2000, the workpiece to be welded 2000 can be stably arranged on the support base 900, so as to improve the position stability of the workpiece to be welded 2000. To a certain extent, it can avoid the displacement of the workpiece to be welded 2000 when the welding tool welds the workpiece to be welded 2000, thereby reducing the welding difficulty and improving the welding quality. When the second pressing mechanism 214 releases the workpiece to be welded 2000, it is convenient to take out the welded workpiece to be welded 2000.

[0127] In some embodiments, in combination with Figure 2 and Figure 10 As shown, the second pressing mechanism 214 includes a second driving member 2141 and a second pressing arm 2142. The second driving member 2141 is arranged on the support base 900. The axis of the second driving member 2141 intersects the support plane 910. The second pressing arm 2142 is connected to the third output end 2143 of the second driving member 2141 and extends toward the workpiece to be welded 2000. The second driving member 2141 is used to drive the second pressing arm 2142 to rotate relative to the workpiece to be welded 2000, so as to facilitate pressing or releasing the workpiece to be welded 2000 by using the second pressing mechanism 214, reduce the pressing difficulty of the workpiece to be welded 2000, and improve the position stability of the workpiece to be welded 2000 to ensure the welding effect.

[0128] It should be noted that since the second pressing mechanism 214 is used to press the workpiece to be welded 2000, compared with the pressing plate 220, the position of the second pressing mechanism 214 can be adaptively adjusted, so that the second pressing mechanism 214 is arranged farther away from the workpiece to be welded 2000 than the first pressing mechanism 211. In this way, while realizing the pressing of the workpiece to be welded 2000 by using the second pressing mechanism 214, it can also avoid the interference between the second pressing mechanism 214 and the welding tool, and there is no problem of interference between the second pressing mechanism 214 and the welding tool due to its relatively high height. In this way, during the welding process of the welding tool, it is not necessary to control the rotation of the second pressing arm 2142 to avoid the welding tool.

[0129] Based on this, in the present application, the axis of the second driving member 2141 of the second pressing mechanism 214 is set to intersect the support plane 910, so that the second driving member 2141 of the second pressing mechanism 214 is formed into a vertical driving member, reducing the installation difficulty of the second pressing mechanism 214, and further reducing the assembly difficulty of the tooling fixture 200.

[0130] In some embodiments, in combination withFigure 1 and Figure 2 As shown, the axis of the second driving member 2141 extends along the Z direction.

[0131] Among them, by arranging the second driving member 2141 on the support base 900, the support base 900 can be used to support the second driving member 2141, improving the position stability of the second driving member 2141, thus ensuring the working performance of the second driving member 2141 to a certain extent and reducing the fixing difficulty of the second driving member 2141.

[0132] In some embodiments, the second driving member 2141 is a driving oil cylinder, which has significant advantages such as high efficiency, flexibility, reliability, and strong load-bearing capacity, enabling the second driving member 2141 to effectively drive the second pressing arm 2142 to rotate relative to the support base 900, thus ensuring the working performance of the second pressing mechanism 214 to a certain extent.

[0133] Of course, in some other embodiments, the second driving member 2141 can also be a driving air cylinder.

[0134] In some embodiments, as Figure 10 shown, the second pressing mechanism 214 further includes a second pressing block 2145, which is arranged at the pressing end of the second pressing arm 2142 and faces the workpiece to be welded 2000, facilitating the use of the second pressing block 2145 to press the workpiece to be welded 2000. While realizing the pressing and fixing of the workpiece to be welded 2000, the contact area between the second pressing arm 2142 and the workpiece to be welded 2000 can also be reduced, thus avoiding damaging the workpiece to be welded 2000 by the second pressing arm 2142 to a certain extent.

[0135] Optionally, the second pressing block 2145 is made of materials such as copper and aluminum.

[0136] In some embodiments, in combination with Figure 2 and Figure 10 shown, the second pressing mechanism 214 includes a third mounting base 2144 and a third transfer shaft 2146. The third mounting base 2144 is arranged on the support base 900, and the second driving member 2141 is fixedly connected to the third mounting base 2144. Thus, the second driving member 2141 is fixedly connected to the support base 900, facilitating the use of the support base 900 to support the second driving member 2141 and improving the position stability of the second driving member 2141.

[0137] Optionally, as Figure 10As shown, the second pressing arm 2142 is rotatably connected to the third output end 2143 of the second driving member 2141 through the third transfer shaft 2146, thereby realizing the rotational connection between the second driving member 2141 and the second pressing arm 2142, reducing the difficulty of the rotational connection between the second driving member 2141 and the second pressing arm 2142, facilitating the use of the second driving member 2141 to drive the second pressing arm 2142 to rotate relative to the support base 900, so as to achieve the purpose of using the second pressing arm 2142 to press or release the workpiece to be welded 2000, and ensuring the working performance of the second pressing arm 2142 to a certain extent.

[0138] Optionally, as Figure 10 shown, the second pressing mechanism 214 further includes a fourth mounting base 2147 and a third transfer member 2148. The fourth mounting base 2147 is fixedly connected to the second driving member 2141. One end of the third transfer member 2148 is rotatably connected to the fourth mounting base 2147, and the middle section of the second pressing arm 2142 is rotatably connected to the other end of the third transfer member 2148. Thus, when the second driving member 2141 drives one end of the second pressing arm 2142 to rotate, the second pressing arm 2142 can effectively rotate relative to the support base 900 to ensure the working performance of the second pressing arm 2142.

[0139] In some embodiments, as shown in combination with Figure 1 and Figure 11 shown, the tooling fixture 200 further includes a slide table assembly 100. The slide table assembly 100 is movably arranged on the support base 900 along the first direction. A pressing member 120 that moves along the second direction is provided on the slide table assembly 100. The pressing member 120 is used to press the workpiece to be welded 2000. When the pressing member 120 moves along the second direction, it rotates synchronously. The second direction intersects with the first direction. Herein, the first direction can be understood as the Y direction shown in Figure 11 , and the second direction can be understood as the Z direction shown in Figure 11 . That is to say, the slide table assembly 100 is arranged on the support base 900 and can move relative to the support base 900 along the Y direction, thereby realizing the adjustment of the position of the slide table assembly 100 on the support base 900. Since the pressing member 120 is provided on the slide table assembly 100, when the slide table assembly 100 moves and adjusts its position along the Y direction, it can drive the pressing member 120 to move along the Y direction. Since the pressing member 120 can move along the Z direction, it is convenient to use the pressing member 120 to press and fix the workpiece to be welded 2000 at different positions in the Y direction. While reducing the fixing difficulty of the workpiece to be welded 2000, it can also improve the position stability of the workpiece to be welded 2000 during welding by the welding tool, which is beneficial to improving the welding quality of the welding tool.

[0140] Meanwhile, by setting the pressing member 120 to rotate synchronously during the movement along the Z direction, the extending direction of the pressing member 120 can be adjusted, so as to facilitate controlling the pressing member 120 to avoid the welding tool, to a certain extent avoiding the pressing member 120 from hindering the welding of the welding tool, thereby reducing the welding difficulty of the workpiece 2000 to be welded and improving the welding quality.

[0141] In some embodiments, as shown in Figure 11 and Figure 12 the sliding table assembly 100 includes a sliding table 110, the sliding table 110 is movably arranged on the support base 900 along a first direction, the pressing member 120 is arranged on the sliding table 110. While realizing the support of the pressing member 120 by the sliding table 110, the sliding table 110 can also drive the pressing member 120 to move along the first direction, so as to facilitate pressing and fixing different positions of the workpiece 2000 to be welded in the first direction by the pressing member 120. While avoiding the welding tool, the position stability of the workpiece 2000 during welding by the welding tool can also be improved.

[0142] In some embodiments, as shown in Figure 11 and Figure 12 the sliding table 110 includes two vertical columns 112 and a cross beam 111. The two vertical columns 112 are arranged at intervals and are respectively movably arranged on the support base 900 of the welding station 1000 along the first direction. The cross beam 111 is connected to one ends of the two vertical columns 112 far from the support base 900, so as to form the sliding table 110 into a gantry structure, thus facilitating movably arranging the sliding table 110 on the support base 900.

[0143] Meanwhile, by connecting the cross beam 111 to one ends of the two vertical columns 112 far from the support base 900, an avoidance space can be formed between the sliding table 110 and the support base 900. The workpiece 2000 to be welded is arranged on the support base 900 and located between the sliding table 110 and the support base 900. While realizing the support of the workpiece 2000 to be welded by the support base 900, the workpiece 2000 to be welded can also be prevented from hindering the movement of the sliding table 110 to a certain extent, so as to facilitate pressing the workpiece 2000 by the pressing member 120 on the sliding table 110.

[0144] In some embodiments, as shown in Figure 11 and Figure 12 the two vertical columns 112 are arranged at intervals in a third direction, and the cross beam 111 extends along the third direction, so that the opposite ends of the cross beam 111 can be respectively connected to the two vertical columns 112, thus facilitating supporting the cross beam 111 by the two vertical columns 112, improving the position stability of the cross beam 111, and thus ensuring the working performance of the cross beam 111.

[0145] Wherein, the third direction mentioned here can be understood as Figure 11 andFigure 12 the X direction shown

[0146] In the description of the present utility model, the features defined as "first", "second", "third" may explicitly or implicitly include one or more of such features, which are used to distinguish and describe features, without order or importance.

[0147] In some embodiments, in combination with Figure 11 and Figure 12 as shown, the pressing member 120 is provided on the cross beam 111 and on the side of the cross beam 111 facing the support base 900. In this way, while realizing that the pressing member 120 is provided on the sliding table 110, the pressing member 120 can be set to face the workpiece to be welded 2000 in the second direction, so as to facilitate pressing the workpiece to be welded 2000 by the pressing member 120 and reduce the fixing difficulty of the workpiece to be welded 2000.

[0148] In some embodiments, in combination with Figure 12 、 Figure 13 and Figure 14 as shown, the sliding table assembly 100 further includes a third driving member 130. The third driving member 130 is provided on the sliding table 110, and the pressing member 120 is connected to the third driving member 130. The third driving member 130 is used to drive the pressing member 120 to move in the second direction and control the pressing member 120 to rotate synchronously when moving. Thus, the pressing member 120 can effectively move relative to the sliding table 110 in the second direction, and the pressing member 120 can rotate synchronously when moving in the second direction, so as to facilitate pressing the workpiece to be welded 2000 by the pressing member 120 and avoiding the welding tool, and reducing the control difficulty of the pressing member 120.

[0149] Wherein, by providing the third driving member 130 on the sliding table 110, the sliding table 110 can be used to support the third driving member 130. While reducing the fixing difficulty of the third driving member 130, the position stability of the third driving member 130 can also be improved, so as to ensure the working performance of the third driving member 130 to a certain extent.

[0150] In some embodiments, in combination with Figure 12 and Figure 13 as shown, both the pressing member 120 and the third driving member 130 include a plurality of them. The plurality of pressing members 120 are arranged on the sliding table 110 at intervals in the third direction. The third driving member 130 corresponds to the pressing member 120 one by one, and the third direction intersects with the first direction and the second direction. Wherein, the third direction mentioned here can be understood as Figure 11 and Figure 12The X direction shown in the figure is the extension direction of the beam 111. The one-to-one correspondence between the third driving member 130 and the clamping member 120 means that each third driving member 130 is connected to a corresponding clamping member 120, so that each clamping member 120 can be controlled by a separate third driving member 130, reducing the difficulty of controlling the clamping member 120.

[0151] Through the above-mentioned arrangement, on the one hand, a plurality of clamping members 120 can be used to simultaneously clamp the workpiece 2000 to be welded, thereby improving the position stability of the workpiece 2000 to be welded; on the other hand, when one of the clamping members 120 avoids the workpiece 2000 to be welded, the workpiece 2000 to be welded can be clamped by other clamping members 120, thereby effectively ensuring the position stability of the workpiece 2000 to be welded during welding and reducing the difficulty of welding.

[0152] In a specific example, when the welding tool moves along the third direction and the pressing member 120 is arranged opposite to the welding tool in the third direction, the pressing member 120 can be controlled in sequence to avoid the welding tool.

[0153] It should be noted that when one of the clamping members 120 avoids the welding tool, the other clamping members 120 all clamp the workpiece 2000 to be welded, so that the slide assembly 100 also has the function of clamping the workpiece 2000 to be welded in the process of avoiding the welding tool, thereby improving the position stability of the workpiece 2000 to be welded.

[0154] In some embodiments, in combination Figure 13 and Figure 14 As shown, the third driving member 130 includes a housing 131, a first output shaft 132 and a second output shaft 133. The first output shaft 132 is fixedly connected in the housing 131 and extends along the second direction. One end of the second output shaft 133 is connected to the first output shaft 132 through a first guide member 134, so that the second output shaft 133 can rotate synchronously when moving along the second direction. The other end of the second output shaft 133 extends out of the housing 131 to connect with the pressing member 120. Thus, the third driving member 130 is connected with the pressing member 120, so that the pressing member 120 can be driven to move by the third driving member 130, and the difficulty of moving the pressing member 120 is reduced.

[0155] Among them, by making the third driving member 130 include a shell 131 and fixing the first output shaft 132 in the shell 131, the shell 131 can be used to support and protect the first output shaft 132, so as to extend the service life of the first output shaft 132 and improve the position stability of the first output shaft 132, thereby improving the working performance of the first output shaft 132.

[0156] Meanwhile, the first output shaft 132 is arranged to extend along the second direction, and one end of the second output shaft 133 is connected to the first output shaft 132 through the first guide member 134. In this way, when the second output shaft 133 is controlled to move along the extending direction of the first output shaft 132, the pressing member 120 can be controlled to move along the second direction, which is convenient for pressing the workpiece to be welded 2000 by the pressing member 120 and reducing the control difficulty of the pressing member 120.

[0157] In some embodiments, as Figure 14 shown, the first guide member 134 includes a guide groove 1341 and guide balls 1342. The guide balls 1342 are movably arranged in the guide groove 1341. One of the guide groove 1341 and the guide balls 1342 is arranged on the first output shaft 132, and the other is arranged on the second output shaft 133. The guide groove 1341 extends along the second direction and at least part of the guide groove 1341 extends circumferentially along the first output shaft 132 or the second output shaft 133. Here, it means that when the guide balls 1342 are arranged on the first output shaft 132, the guide groove 1341 is arranged on the second output shaft 133 and at least part of the guide groove 1341 extends circumferentially along the second output shaft 133; correspondingly, when the guide balls 1342 are arranged on the second output shaft 133, the guide groove 1341 is arranged on the first output shaft 132 and at least part of the guide groove 1341 extends circumferentially along the first output shaft 132. In this way, when the second output shaft 133 moves relative to the first output shaft 132, the guide balls 1342 can be driven to move along the extending path of the guide groove 1341. Since the guide groove 1341 extends along the second direction and at least part of the guide groove 1341 extends circumferentially along the first output shaft 132 or the second output shaft 133, the cooperation between the guide balls 1342 and the guide groove 1341 can drive the pressing member 120 to move along the second direction and rotate synchronously, which is convenient for controlling the rotation of the pressing member 120 relative to the sliding table 110 to avoid the welding tool.

[0158] In some embodiments, as Figure 14 shown, the guide balls 1342 are arranged on the second output shaft 133, and the guide groove 1341 is arranged on the first output shaft 132 and at least part of the guide groove 1341 extends circumferentially along the first output shaft 132, so as to drive the pressing member 120 to rotate synchronously when moving along the second direction by the cooperation of the guide balls 1342 and the guide groove 1341, and reduce the control difficulty of the pressing member 120.

[0159] Of course, in some other embodiments, the guide balls 1342 can also be arranged on the first output shaft 132, and the guide groove 1341 is arranged on the second output shaft 133 and at least part of the guide groove 1341 extends circumferentially along the second output shaft 133. In this way, the cooperation between the guide balls 1342 and the guide groove 1341 can also drive the pressing member 120 to rotate synchronously when moving along the second direction.

[0160] In some embodiments, there are multiple guiding balls 1342 and multiple guiding grooves 1341. The multiple guiding grooves 1341 and the multiple guiding balls 1342 correspond to each other one by one, which can increase the matching strength between the first output shaft 132 and the second output shaft 133. As a result, when the guiding balls 1342 and the guiding grooves 1341 cooperate, they can effectively drive the pressing member 120 to rotate synchronously when moving in the second direction, ensuring the working performance of the pressing member 120 to a certain extent.

[0161] In some embodiments, as Figure 14 shown, the first guiding member 134 further includes an elastic member 1343. The elastic member 1343 is used to drive the guiding ball 1342 to move towards the guiding groove 1341, enabling the guiding ball 1342 to effectively cooperate within the guiding groove 1341. Thus, the guiding ball 1342 can effectively move along the extending direction of the guiding groove 1341, realizing the guiding cooperation between the guiding ball 1342 and the guiding groove 1341, facilitating the synchronous rotation of the second output shaft 133 when moving in the second direction, and reducing the control difficulty of the pressing member 120.

[0162] Among them, the elastic member 1343 mentioned here can be a spring, a rubber member, or the like.

[0168] Optionally, as Figure 15 shown, the tool changing mechanism 700 and the grinding device 800 are arranged on one side of the tooling fixture 200.

The grinding device 800 solves the problem of aluminum chips adhering to the welding tool during the welding process, further improving the welding efficiency and quality.

[0169] In some embodiments, as Figure 15 shown, the welding station 1000 includes two welding robots 600. The two welding robots 600 cooperate to improve the welding efficiency, solve complex welding trajectories, and improve the rhythm of the entire welding station 1000 and the appearance quality of the product.

During the specific welding process, the slide table assembly 100 cooperates with the two welding robots 600 and exchanges signals with each other, and they cooperate with each other to weld the workpiece to be welded 2000 to achieve fully automated welding.
