Description

Technical Field

[0001] This utility model relates to the field of production technology of machinery, specifically to a welding positioning fixture and welding equipment. Background Technology

[0002] In the production of operating machinery, the cab side panel is composed of multiple parts, and is generally manufactured through welding. In actual production, the cab side panel comprises a large number of parts, so production personnel typically perform preliminary welding assembly of these parts to obtain multiple components to be welded. However, further welding between these components requires high precision in their positioning, making direct manual welding impossible.

[0003] In existing technologies, welding equipment is generally equipped with corresponding welding positioning fixtures to position multiple parts to be welded before welding. However, existing welding positioning fixtures often simply clamp and fix multiple parts to be welded in their respective welding positions, and positional deviations may still occur when the parts to be welded are subjected to accidents such as collisions. Utility Model Content

[0004] The purpose of this invention is to overcome the problem that in the prior art, welding positioning fixtures often simply press and fix multiple parts to be welded in their corresponding welding positions, and when the parts to be welded are subjected to accidents such as collisions, positional deviations may still occur.

[0005] To achieve the above objectives, this utility model provides a welding positioning fixture for welding and positioning the side wall of the cab of a work machine. The side wall of the cab includes multiple first welded parts, and the welding positioning fixture includes: Base; Multiple first support base modules are all set on the base and together form multiple installation areas for the installation of multiple first welded parts in a one-to-one correspondence. The first support base module has a first clamping part and a second clamping part that are perpendicular to each other. Multiple first rotating arm modules are arranged one-to-one in each installation area and can rotate relative to the support base module. Each first rotating arm module has a third clamping part and a fourth clamping part that are perpendicular to each other. The third clamping part is used to cooperate with the first clamping part to clamp the first welded part from the width direction of the first welded part. The fourth clamping part is used to cooperate with the second clamping part to clamp the first welded part from the direction perpendicular to the plane where the first welded part is located. Multiple first positioning modules are set one-to-one in each installation area and are used to install and position the first welded component.

[0006] In embodiments of this application, the first rotating arm module includes: The swing arm mounting base is detachably installed on the base. A rotating arm is rotatably mounted on the top of a rotating arm mounting base, and both the third and fourth clamping parts are formed on the rotating arm.

[0007] In embodiments of this application, the first rotating arm module further includes a handle disposed on the rotating arm and used to drive the rotating arm to move.

[0008] In embodiments of this application, the cab side panel further includes a side panel connecting plate for connecting to the first column welded member among a plurality of first welded members, and the welding positioning fixture further includes: Multiple second support modules are all mounted on the base and together form a placement surface on their top for placing the side panel connecting plate; Multiple second rotating arm modules are rotatably mounted on the base and correspond one-to-one with multiple second support base modules. The second rotating arm modules and the corresponding second support base modules cooperate with each other to press the side wall connecting plate from a direction perpendicular to the side wall connecting plate.

[0009] In embodiments of this application, the cab side panel further includes a second welded component, one end of which is used to connect with the side panel connecting plate, and the other end of which is used to connect with the top pillar welded component among the plurality of first welded components. The welding positioning fixture further includes: Multiple third support modules are all set on the base and together form a receiving groove with an upward opening for placing the second welded part; Multiple third rotating arm modules are rotatably mounted on the base and correspond one-to-one with multiple third support base modules. The third rotating arm modules and the corresponding third support base modules cooperate with each other to press the second welded part from a direction perpendicular to the bottom wall of the receiving groove.

[0010] In embodiments of this application, the first support base module and / or the second support base module and / or the third support base module are movably disposed on the base.

[0011] In embodiments of this application, the cab side panel further includes a third welded member for mounting to a second column welded member among a plurality of first welded members, and the welding positioning fixture further includes: The transfer module is movably mounted on the base and is used to transfer the third weldment to a preset welding position, which is located on the side wall of the second column weldment.

[0012] In the embodiments of this application, each first positioning module includes four positioning parts, which correspond one-to-one with the first pressing part, the second pressing part, the third pressing part and the fourth pressing part, and are respectively located on the side of the first pressing part near the first welded part, the side of the second pressing part near the first welded part, the side of the third pressing part near the first welded part and the side of the fourth pressing part near the first welded part.

[0013] In embodiments of this application, the welding positioning fixture further includes: The second positioning module is retractably mounted on the base and is used to position the perforations on the top column weldment among the multiple first welded parts.

[0014] This application also proposes a welding apparatus, comprising: The welding positioning fixture is as described above; The positioner's rotating shaft is connected to the base of the welding positioning fixture; The welding robot is positioned on one side of the welding positioning fixture.

[0015] As can be seen from the above technical solution, in this application, the welding positioning fixture supports and installs multiple first welding parts through the second clamping parts in multiple first support base modules, and positions the multiple first welding parts to the welding positions through multiple first positioning modules. In practical applications, when welding the cab side panel, it is necessary to assemble and position the various components of the cab side panel. During assembly and positioning, some components of the cab side panel are limited by other parts, and their positions are relatively fixed, so the positioning difficulty is relatively small, and positional deviation is less likely to occur. The first welding parts of the cab side panel rely entirely on the welding positioning fixture for positioning, and their positions are more prone to deviation. Therefore, the positioning accuracy requirements for the first welding parts are high, and further fixation is required after positioning is completed. In this application, the welding positioning fixture allows multiple first rotating arm modules to rotate toward their corresponding first support base modules. This allows the first clamping part on the first support base module to engage with the third clamping part on the first rotating arm module, applying a clamping force in the width direction to the first welded component. Furthermore, the second clamping part on the first support base module engages with the fourth clamping part on the first rotating arm module, applying a clamping force perpendicular to the plane of the first welded component, thus fixing the first welded component from multiple directions. The welding positioning fixture proposed in this application can fix each first welded component in multiple directions, resulting in superior fixing capability.

[0016] Other features and advantages of the embodiments of this application will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] Figures 1 to 5 This is a schematic diagram of an embodiment of the welding positioning fixture proposed in this application. Please refer to... Figure 1 and Figure 4The embodiments of this application provide a welding positioning fixture 100, which is used to weld and position the cab side panel 200 of the operating machinery. The cab side panel 200 includes a plurality of first welded parts 210. The welding positioning fixture 100 includes: a base 1, a plurality of first support base modules 2, a plurality of first rotating arm modules 3 and a plurality of first positioning modules 4. Multiple first support base modules 2 are disposed on the base 1 and together form multiple installation areas for the one-to-one installation of multiple first welded parts 210. Each first support base module 2 has a first clamping part 21 and a second clamping part 22 that are perpendicular to each other. Multiple first rotating arm modules 3 are disposed in each installation area and can rotate relative to the support base modules. Each first rotating arm module 3 has a third clamping part 31 and a fourth clamping part 32 that are perpendicular to each other. The third clamping part 31 is used to cooperate with the first clamping part 21 to clamp the first welded part 210 from the width direction of the first welded part 210. The fourth clamping part 32 is used to cooperate with the second clamping part 22 to press the first welded part 210 from the direction perpendicular to the plane where the first welded part 210 is located. Multiple first positioning modules 4 are disposed in each installation area and are used to install and position the first welded part 210.

[0021] In this application, the welding positioning fixture 100 supports and mounts multiple first welding parts 210 via the second clamping parts 22 in multiple first support modules 2, and positions the multiple first welding parts 210 to the welding position via multiple first positioning modules 4. In practical applications, when welding the cab side panel 200, it is necessary to assemble and position the various components of the cab side panel 200. During assembly and positioning, some components of the cab side panel 200 are limited by other parts, and their positions are relatively fixed, so the positioning difficulty is relatively small and positional deviation is less likely. The first welding parts 210 of the cab side panel 200 rely entirely on the welding positioning fixture 100 for positioning, and their positions are more prone to deviation. Therefore, the first welding parts 210 require high positioning accuracy and need further fixation after positioning. In this application, the welding positioning fixture 100 allows multiple first rotating arm modules 3 to rotate toward their corresponding first support base modules 2. This allows the first clamping part 21 on the first support base module 2 to engage with the third clamping part 31 on the first rotating arm module 3, applying a clamping force in the width direction to the first welded part 210. Furthermore, the second clamping part 22 on the first support base module 2 engages with the fourth clamping part 32 on the first rotating arm module 3, applying a clamping force perpendicular to the plane containing the first welded part 210, thus fixing the first welded part 210 from multiple directions. The welding positioning fixture 100 proposed in this application can fix each first welded part 210 in multiple directions, resulting in superior fixing capability.

[0022] Specifically, please refer to Figure 1 and Figure 3 The first rotating arm module 3 includes a rotating arm mounting base 33 and a rotating arm 34. The rotating arm mounting base 33 is detachably mounted on the base 1. The rotating arm 34 is rotatably mounted on the top of the rotating arm mounting base 33. The third pressing part 31 and the fourth pressing part 32 are both formed on the rotating arm 34.

[0023] The boom mounting base 33 is detachably mounted to the base 1 via bolt assemblies. Therefore, when the welding positioning fixture 100 needs to perform welding positioning on different models of cab side panels 200, the boom mounting base 33 can be easily adjusted by disassembling and changing its mounting position. Furthermore, the boom mounting base 33 can be disassembled for maintenance and upkeep, thereby extending its service life. The boom 34 is rotatably mounted on the top of the boom mounting base 33 via a pivot. When the first boom module 3 is working, the boom 34 rotates towards the first welded part 210 and is fixed to the first welded part 210 by the third clamping part 31 and the fourth clamping part 32.

[0024] It should be noted that there are many ways for the first rotating arm module 3 to drive the rotating arm 34. For example, the first rotating arm module 3 can drive the rotating arm 34 through a cylinder, hydraulic cylinder, or motor, and the specific method can be selected and replaced according to actual needs. In this application, the rotating arm 34 generally approaches the first welded part 210 from top to bottom or bottom to top, while the third clamping part 31 clamps the first welded part 210 from the width direction. Therefore, when the first welded part 210 is misaligned, the third clamping part 31 may interfere with the first welded part 210 during the movement of the rotating arm 34. Therefore, preferably, in this application, the first rotating arm module 3 drives the rotating arm 34 to move through a cylinder controlled by a manual valve. In actual production, the worker can first manually rotate the rotating arm 34 to overlap with the first welded part 210. After confirming that the position of the first welded part 210 is correct, the worker can then control the manual valve to start the cylinder to fix the first welded part 210 in the corresponding welding position.

[0025] Further, please refer to Figures 1 to 3 The first rotating arm module 3 also includes a handle 35 disposed on the rotating arm 34 and used to drive the rotating arm 34 to move. In a preferred embodiment of this application, the first rotating arm module 3 drives the rotating arm 34 to move by a cylinder controlled by a manual valve. The worker needs to manually rotate the rotating arm 34 to overlap with the first welded part 210 first. After confirming that the position of the first welded part 210 is correct, the worker then controls the manual valve to start the cylinder. In the above production process, the worker needs to perform certain manual operations on the rotating arm 34, and the handle 35 disposed on the rotating arm 34 can assist in this, making it more convenient for the worker to operate.

[0026] Please see Figures 1 to 4 In one embodiment of this application, the cab side panel 200 further includes a side panel connecting plate 220 for connecting with the first column welding member 211 among the plurality of first welding members 210. The welding positioning fixture 100 further includes: a plurality of second support base modules 5 and a plurality of second rotating arm modules 6. The plurality of second support base modules 5 are all disposed on the base 1 and have a common placement surface 51 on their top for placing the side panel connecting plate 220; the plurality of second rotating arm modules 6 are rotatably disposed on the base 1 and correspond one-to-one with the plurality of second support base modules 5. The second rotating arm modules 6 and the corresponding second support base modules 5 cooperate with each other to press the side panel connecting plate 220 from a direction perpendicular to the side panel connecting plate 220.

[0027] The welding positioning fixture 100 proposed in this application is used to position the cab side panel 200. The cab side panel 200 includes multiple first welded components 210, such as a first pillar welded component 211 (B-pillar), a second pillar welded component 213 (A-pillar), a top pillar welded component 212 (top pillar), and a bottom rod welded component 214 (bottom rod). The cab side panel 200 also includes a side panel connecting plate 220, which is essentially the side panel itself. During actual installation, the top pillar welded component 212 is connected to the same end of the first pillar welded component 211 and the second pillar welded component 213, while the bottom rod welded component 214 is connected to the other end of the first pillar welded component 211 and the second pillar welded component 213. One side of the side panel connecting plate 220 is connected to the first pillar welded component 211.

[0028] The side panel connecting plate 220 has a plate-like structure, making it difficult to fix it in the width direction. Therefore, the welding positioning fixture 100 additionally provides multiple second support base modules 5 and multiple second rotating arm modules 6 to position the side panel connecting plate 220. The multiple second support base modules 5 together form a placement surface 51 for placing the side panel connecting plate 220, while the multiple second rotating arm modules 6 are rotatably mounted on the base 1. The multiple second rotating arm modules 6 can rotate toward the placement surface 51, and when rotating toward the placement surface 51, the second rotating arm modules 6 can press the side panel connecting plate 220 against the placement surface 51 of the second support base modules 5. The welding positioning fixture 100 fixes the relatively uniform first welded part 210 in multiple directions and angles to ensure that the first welded part 210 is in the corresponding welding position, while adapting to the more unique side panel connecting plate 220 to formulate the most suitable fixing structure and ensure the fixing effect.

[0029] It is important to note that during actual installation, the side panel connecting plate 220 is not on the same plane as other workpieces; the plane containing the side panel connecting plate 220 is angled to the plane containing other workpieces. This is determined by the actual structure of the cab side panel 200. Therefore, the extension direction of the placement surface 51 formed by the multiple second support base modules 5 is consistent with the extension direction of the side panel connecting plate, rather than extending horizontally. The multiple second swing arm modules 6 do not press the side panel connecting plate vertically, but rather press it from a direction perpendicular to the side panel connecting plate 220, thus avoiding the pressing effect being affected by the tilt angle of the side panel connecting plate 220. In fact, when other parts to be welded are in the same situation as described above, the corresponding support base modules and swing arm modules can also be adjusted for compatibility to ensure the fixing effect of the swing arm modules and support base modules on the parts to be welded.

[0030] Please see Figure 1 , Figure 3 and Figure 4 In some embodiments, the cab side panel 200 further includes a second welded component 230. One end of the second welded component 230 is used to connect with the side panel connecting plate 220, and the other end is used to connect with the top column welded component 212 among the plurality of first welded components 210. The welding positioning fixture 100 also includes a plurality of third support base modules 7 and a plurality of third rotating arm modules 8. The plurality of third support base modules 7 are all disposed on the base 1 and together form a receiving groove 71 for placing the second welded component 230 with an upward opening. The plurality of third rotating arm modules 8 are rotatably disposed on the base 1 and correspond one-to-one with the plurality of third support base modules 7. The third rotating arm modules 8 and the corresponding third support base modules 7 cooperate with each other to press the second welded component 230 from a direction perpendicular to the bottom wall of the receiving groove 71.

[0031] In practice, the second welded component 230 is the rear side pillar of the cab side panel 200, and the top pillar welded component 212 is the top pillar of the cab side panel 200. Therefore, in practical applications, one end of the second welded component 230 can be directly connected to the side panel connecting plate 220, and the second welded component 230 can be directly connected to the top pillar welded component 212. Thus, after installation in the welding positioning fixture 100, the second welded component 230 has relatively low freedom in its length direction, and the possibility of displacement or positional deviation in its length direction is low. It does not have high requirements for its fixing effect. The welding positioning fixture 100 accommodates the second welded component 230 through the receiving groove 71 on the third support module 7, thereby limiting the second welded component 230 in the width direction and preventing displacement.

[0032] Multiple third support modules 7 are spaced apart along the length of the second welded component 230, and each third support module 7 has an upward-facing receiving groove 71. The receiving groove 71 is through-shaped along the length of the second welded component 230, so that the receiving grooves 71 on the multiple third support modules 7 can communicate with each other to accommodate the second welded component 230. When the second welded component 230 is installed in the receiving groove 71, the second welded component 230 will not shift too much in its width direction, and the multiple third rotating arm modules 8 can all rotate toward the second welded component 230, thereby pressing the second welded component 230 tightly into the receiving groove 71.

[0033] Furthermore, the first support module 2, the second support module 5, and the third support module 7 can be movably mounted on the base 1, or optionally fixedly mounted on the base 1. When the first support module 2, the second support module 5, and the third support module 7 are movably mounted on the base 1, their positions on the base 1 can be adjusted, thereby positioning different models of the cab side panel 200 to meet more diverse usage needs. When the first support module 2, the second support module 5, and the third support module 7 are fixedly mounted on the base 1, the fixing effect of the first support module 2, the second support module 5, and the third support module 7 is more stable, and positional deviations caused by frequent movements can be avoided.

[0034] The base 1 can be provided with multiple different mounting points, such as multiple sets of mounting threaded holes, corresponding to the first support base module 2, the second support base module 5, and the third support base module 7. The base 1 can also be provided with multiple sliding mounting seats, and the first support base module 2, the second support base module 5, and the third support base module 7 are then installed onto their respective sliding mounting seats. The above is an example of a specific implementation method when the first support base module 2, the second support base module 5, and the third support base module 7 require movable installation. The first support base module 2, the second support base module 5, and the third support base module 7 can adopt different configuration methods, and the specific configuration method can be selected according to actual needs.

[0035] Specifically, please refer to Figure 1 and Figure 3 The cab side panel also includes a guide rail mounted above the welded part of the second column, and the welding positioning fixture also includes a guide rail positioning module. The guide rail positioning module includes a positioning rotating arm unit and a guide rail positioning component. The positioning rotating arm unit is rotatably mounted on the base and is used to rotate to the top of the second column during positioning operations; the guide rail positioning component is mounted on the positioning rotating arm unit and is used to install and position the guide rail placed on the top of the second column during positioning operations.

[0036] During the positioning operation, the positioning arm unit rotates towards the second column. As the positioning arm unit rotates, the guide rail positioning component moves along with it. After the positioning operation is complete, the positioning arm unit carries the guide rail positioning component to the top of the second column, allowing it to contact and position the guide rail placed on top of the second column. Furthermore, the positioning arm unit also includes an arm mounting base and an arm mounted on the mounting base, and the guide rail positioning component can be a positioning block mounted on this arm. When the guide rail positioning component moves to the top of the second column with the positioning arm unit, it positions the guide rail by abutting against it. Through the movement of the positioning arm unit, the guide rail positioning component avoids the location of the second column and completes the positioning of the guide rail, improving the comprehensiveness of the welding positioning fixture's positioning function.

[0037] It should be noted that there is no limit to the number of positioning arm units and guide rail positioning components. The specific number can be adjusted according to the number of guide rail positioning components required by the guide rail.

[0038] Please see Figures 1 to 3 The cab side panel 200 comprises several small components, which are often difficult to position and fix due to their size limitations, and welding points are difficult to avoid. Therefore, in one embodiment of this application, the cab side panel 200 also includes a third welded component 240 for mounting to a second column welded component 213 among a plurality of first welded components 210. The welding positioning fixture 100 also includes a transfer module 110, which is movably mounted on the base 1 and used to transfer the third welded component 240 to a preset welding position located on the side wall of the second column welded component 213.

[0039] In actual production, the third welded component 240 can be installed on the transfer module 110, and the rotation module drives the third welded component 240 to move, thereby transferring the third welded component 240 to the preset welding position. In the actual application of the welding positioning fixture 100 proposed in this application, the preset welding position of the third welded component 240 is set on the second column welded component 213. Specifically, the third welded component 240 is a sheet metal part with a central opening that needs to be erected on the second column welded component 213. Therefore, the positioning difficulty of the third welded component 240 and the difficulty of avoiding welding points are both relatively high.

[0040] Therefore, the transfer module 110 includes a telescopic rod corresponding to the third welded component 240. The cross-sectional shape of the telescopic rod is the same as the shape of the hole in the middle of the third welded component 240, and the diameter of the telescopic rod gradually increases from the end near the third welded component 240 to the end away from the third welded component 240, so that the third welded component 240 can be sleeved onto the telescopic rod from its end. When the telescopic rod extends, it carries the third welded component 240 to the preset welding position. The telescopic rod itself is smaller and farther away from the welding position of the third welded component 240, thereby avoiding interference with the welding of the third welded component 240. After the welding of the third welded component 240 is completed, the telescopic rod can be directly retracted from the third welded component 240 without any additional operation.

[0041] Specifically, please refer to Figure 5 Each first positioning module 4 includes four positioning parts 41, which correspond one-to-one with the first pressing part 21, the second pressing part 22, the third pressing part 31 and the fourth pressing part 32, and are respectively located on the side of the first pressing part 21 near the first welded part 210, the side of the second pressing part 22 near the first welded part 210, the side of the third pressing part 31 near the first welded part 210 and the side of the fourth pressing part 32 near the first welded part 210.

[0042] Each of the four positioning parts 41 is specifically designed as a block structure, ensuring relatively stable contact with the first welded component 210. When the first rotating arm module 3 rotates towards the first welded component 210, the first positioning module 4 contacts the first welded component 210 through the four positioning parts 41. Driven by the third pressing part 31 and the fourth pressing part 32, the positioning parts 41 apply a pushing force and a pressing force to the first welded component 210, thereby cooperating to fix the first welded component 210 in the corresponding welding position. The first positioning module 4 positions the first welded component 210 to the corresponding welding position through the four positioning parts 41, and fixes the first welded component 210 in the corresponding welding position through the first pressing part 21, the second pressing part 22, the third pressing part 31, and the fourth pressing part 32, resulting in better and more stable positioning.

[0043] Please see Figure 1In the components of the cab side panel 200, some of the parts to be welded have hole-like or groove-like structures. When the welding positioning fixture 100 uses the hole-like or groove-like structures on the parts to be welded for positioning, the positioning effect is better and the stability is also better. Therefore, in one embodiment of this application, the welding positioning fixture 100 also includes a second positioning module 9. The second positioning module 9 is telescopically mounted on the base 1 and is used to position the through holes on the top column welded parts 212 among the multiple first welded parts 210. The top column welded parts 212 have through holes, and the telescopic positioning part 41 of the second positioning module 9 (such as a telescopic cylinder) (the telescopic positioning part 41 can be rod-shaped or column-shaped) can be inserted into the through holes of the top column welded parts 212 to complete the positioning. Of course, other parts to be welded with hole-like or groove-like structures can also be positioned in this way. Here, the top column welded parts 212 are only used as an example. In specific applications, the second positioning module 9 can be set according to the actual situation.

[0044] This application also proposes a welding device, which includes a welding positioning fixture 100, a positioner, and a welding robot. The welding positioning fixture 100 is a welding positioning fixture 100 for the side panel 200 of the cab of the operating machinery as described in any of the above embodiments; the rotating shaft of the positioner is connected to the base 1 of the welding positioning fixture 100; the welding robot is located on one side of the welding positioning fixture 100.

[0045] The welding equipment uses a welding positioning fixture 100 to position the various components of the cab side panel 200. A positioner rotates the welding positioning fixture 100 to adjust it to a suitable welding angle. Finally, a welding robot welds the cab side panel 200. The welding positioning fixture 100 provides accurate and stable positioning, thereby improving the welding accuracy of the welding equipment and increasing the production qualification rate.
