Description

Technical Field

[0001] This application relates to the field of automotive manufacturing technology, and in particular to a standard workbench. Background Technology

[0002] In automobile manufacturing production lines, the body-in-white and various sub-assemblies undergo multiple processing steps, including welding, painting, and final assembly. Each processing station requires a dedicated support platform or process tray to support and position the product to be processed, meeting the needs of robotic or manual operations. However, the product structure, support point locations, and positioning requirements vary depending on the vehicle model and the specific process. In traditional production models, each process station is typically equipped with a dedicated support platform corresponding to a specific product at that process. When a product moves to the next process, lifting equipment or handling devices are needed to transfer the product from the current support platform to another support platform at the next station.

[0003] Because the support and fixing points differ for each vehicle model, whenever a new model is prototyped or a model is redesigned, the fixing points of the original bodywork support platform need to be modified or even redesigned and manufactured, resulting in wasted time and increased costs in production. Furthermore, when products move between different processes, they require repeated hoisting, transfer, and repositioning. Additionally, after hoisting into place, the installation of water, electricity, and communication lines is necessary, which not only reduces the production cycle time but also affects overall production efficiency. Summary of the Invention

The hinge end of the first gripper is hinged to the housing. The clamping end of the first gripper extends to both sides of the first insertion hole. An inclined strip hole is provided in the middle of the first gripper. The edge of the lifting plate rolls with the strip hole. The telescopic device drives the lifting plate to rise and fall, thereby causing the first grippers on both sides to open or retract synchronously, so that the clamping end of the first gripper releases or clamps the first pin inserted into the first insertion hole.

[0015] In an optional or preferred embodiment, the first locking mechanism further includes a base plate, which is fixed to the bottom of the housing, and the hinged end of the first gripper is hinged to the base plate.

The other end of the second gripper extends to both sides of the second insertion hole. The telescopic drive component is used to drive the translation plate to move closer to or away from the fixed plate in the horizontal direction, so that the second gripper can release or clamp the second pin inserted into the second insertion hole.

[0023] In an optional or preferred embodiment, the second locking mechanism further includes a third telescopic damping rod, the cylinder of which is fixedly connected to the translation plate, and the telescopic rod of which is connected to the fixed plate.

[0024] In an optional or preferred embodiment, a second return spring is sleeved on the telescopic rod of the third telescopic damping rod. One end of the second return spring is connected to the fixed plate, and the other end is connected to the cylinder of the third telescopic damping rod.

[0025] Based on the above technical solution, the embodiments of this application have at least the following beneficial effects: By placing the product on a quick-change workbench and allowing it to circulate as a whole between processes, this application avoids repeated hoisting and repositioning of the product between different support platforms, thereby improving production cycle time and increasing production efficiency.

[0043] In automobile manufacturing production lines, the body-in-white and various sub-assemblies undergo multiple processing steps, including welding, painting, and final assembly. Each processing station requires a dedicated support platform or process tray to support and position the product to be processed, meeting the needs of robotic or manual operations. However, the product structure, support point locations, and positioning requirements vary depending on the vehicle model and the specific process. In traditional production models, each process station is typically equipped with a dedicated support platform corresponding to a specific product at that process. When a product moves to the next process, lifting equipment or handling devices are needed to transfer the product from the current support platform to another support platform at the next station.

[0044] Because the support and fixing points are located differently for each vehicle model, whenever a new model is prototyped or a model is redesigned, the fixing points of the original body process support platform need to be modified or even redesigned and manufactured, resulting in wasted time and increased costs in production. In addition, when the product flows between different processes, it needs to be repeatedly hoisted, transferred, and repositioned, which reduces the production cycle and affects overall production efficiency.

[0045] Reference Figures 1 to 8 This application provides a standard workbench, including a fixed base 100, a platform 200, and a quick-change workbench 300.

[0046] The fixed base 100 is embedded and fixed in the ground, serving as the supporting foundation for the entire standard workbench. The platform 200 is detachably mounted on the fixed base 100. The quick-change workbench 300 is used to directly support the workpiece to be processed, and it can quickly dock with and separate from the platform 200.

[0047] In one embodiment of this application, four fixing bases 100 are provided, and the four fixing bases 100 are distributed in a rectangular array on the ground.

[0048] The platform 200 includes a support platform 210 and support columns 220. Four support columns 220 are provided. The support platform 210 has a rectangular platform structure, and a support column 220 is vertically installed at each of the four corners of the support platform 210. The bottoms of the four support columns 220 correspond one-to-one with the four fixed seats 100 and cooperate with each other, thereby stably supporting the platform 200 on the ground.

[0049] Of course, in other embodiments, three fixed bases 100 can be provided, arranged in a triangular pattern on the ground. Correspondingly, the support platform 210 can be set as a triangle, and three support columns 220 can also be provided.

[0050] The top of the mounting base 100 is provided with a first socket 121 and a first water and electricity communication interface 140. The first water and electricity communication interface 140 is used to realize the water, electricity and communication connection between the platform 200 and the mounting base 100. A first locking mechanism 130 is provided inside the mounting base 100 at the position corresponding to the first socket 121.

[0051] The bottom of the support column 220 is provided with a first pin 221, the position and shape of which match the first socket 121, and the first pin 221 can be inserted into the first socket 121. After the first pin 221 is inserted into the first socket 121, the first pin 221 is locked by the first locking mechanism 130, thereby fixing the support column 220 to the fixed base 100. The bottom of the support column 220 is also provided with a second water and electricity communication interface 222. When the platform 200 is docked with the fixed base 100, the second water and electricity communication interface 222 and the first water and electricity communication interface 140 are docked to achieve the connection of water, electricity and signal paths.

[0052] In this embodiment, the support column 220 of the platform 200 has a hollow structure. For example, the support column 220 can be made of square hollow steel. The support column 220 not only provides support but also serves as a cable receiving channel.

[0053] Specifically, the second water and electricity communication interface 222 is located on one side of the bottom of the support column 220. The side of the bottom of the support column 220 is provided with a cable routing hole. The cable led out from the second water and electricity communication interface 222 enters the internal cavity of the support column 220 through the cable routing hole and runs upward along the internal cavity of the support column 220. This simplifies the external pipeline layout of the entire platform 200 and avoids the risk of cable entanglement and wear.

[0054] To prevent damage to the second hydroelectric communication interface 222 and the wiring hole from external dust or impact, a protective shell 223 is provided on the outside of the second hydroelectric communication interface 222. The protective shell 223 is fixedly connected to the support column 220 and completely covers the wiring hole.

[0055] The top of the support platform 210 is provided with a second socket 211, and a second locking mechanism 240 is provided inside the support platform 210 at the position corresponding to the second socket 211. The support platform 210 is also provided with a third water and electricity communication interface 230, which is connected to the second water and electricity communication interface 222 through the space inside the support platform 210 and the hollow support column 220.

[0056] The quick-change worktable 300 is an independent modular component, with its top surface used to support the object to be processed. The bottom of the quick-change worktable 300 is equipped with a second pin 310, the position and shape of which match the second socket 211 on the top of the support platform 210. The bottom of the quick-change worktable 300 also has a fourth water and electricity communication interface 320. When the quick-change worktable 300 is installed on the support platform 210, the second pin 310 is inserted into the second socket 211 and locked by the second locking mechanism 240. Simultaneously, the fourth water and electricity communication interface 320 connects with the third water and electricity communication interface 230 on the support platform 210, achieving mechanical fixation between the quick-change worktable 300 and the carrier platform 200, as well as communication of water, electricity, and signals.

[0057] The quick-change worktable 300 is a carrier specifically designed for different products. When switching between different products, only the quick-change worktable 300 needs to be replaced, without any modification to the fixed base 100 and the platform 200. Since the platform 200 provides a unified mechanical interface (i.e., the second socket 211) and a unified energy communication interface (i.e., the third water and electricity communication interface 230), all different specifications of the quick-change worktable 300 use the same bottom interface (i.e., the second pin 310 and the fourth water and electricity communication interface 320), thus achieving a plug-and-play effect when switching between different products.

[0058] This application integrates a product-specific positioning and support structure onto a quick-change workbench 300. When the vehicle model on the production line changes, only the corresponding quick-change workbench 300 needs to be designed and manufactured according to the support point position of the new model; the existing fixed base 100 and platform 200 can be reused. This not only shortens the cycle of model changeover and modification but also avoids a large amount of repetitive investment in basic equipment, significantly reducing production costs. By carrying the product on the quick-change workbench 300 and allowing it to circulate as a whole between processes, repeated lifting and repositioning of the product between different support platforms is avoided, improving production cycle time and increasing production efficiency. This application integrates water, electricity, and communication interfaces. When the platform 200 is installed on the fixed base 100 and the quick-change workbench 300 is placed on the platform 200, the water, electricity, and communication connections are completed simultaneously, without any manual wiring operations. This not only greatly shortens product changeover time but also eliminates safety hazards caused by manual wiring errors, improving production efficiency.

[0059] The mounting base 100 includes a housing 110 and a top plate 120. The top of the housing 110 has an opening, and the top plate 120 is installed on the top of the housing 110 to block the opening. A first socket 121 is provided on the top plate 120, and the top plate 120 is exposed to the ground surface. A first water and electricity communication interface 140 is provided on the top plate 120.

[0060] In one embodiment of this application, the first locking mechanism 130 includes a telescopic device 131, a lifting plate 132, and a first gripper 133.

[0061] The telescopic device 131 is disposed inside the housing 110. The fixed end of the telescopic device 131 is connected to the housing 110, and the telescopic movable end of the telescopic device 131 extends toward the top plate 120. In this embodiment, the telescopic device 131 is a first telescopic damping rod, which can be a hydraulic damping rod, a pneumatic damping rod, or a spring damping rod. The cylinder of the first telescopic damping rod is connected to the bottom of the housing 110, and the piston rod of the first telescopic damping rod is connected to the lifting plate 132. When the piston rod of the first telescopic damping rod extends, it pushes the lifting plate 132 toward the top plate 120.

[0062] The lifting plate 132 is installed at the telescopic movable end of the telescopic device 131. The lifting plate 132 is roughly a horizontal flat plate that can slide freely in the vertical direction within the housing 110. The vertical projection of the first insertion hole 121 is located on the lifting plate 132, that is, the lifting plate 132 is positioned directly below the first insertion hole 121.

[0063] The first gripper 133 is disposed on both sides of the lifting plate 132. Specifically, there are two first grippers 133, which are disposed opposite to each other on the left and right sides of the lifting plate 132. One end of the first gripper 133 is a hinge end, and the other end is a clamping end. The hinge end of the first gripper 133 is hinged to the housing 110, and the clamping end of the first gripper 133 extends to both sides of the first insertion hole 121. An inclined extending strip hole 1331 is provided in the middle of the first gripper 133, and a roller or pin is provided on the edge of the lifting plate 132. The roller or pin is embedded in the strip hole 1331 and forms a rolling engagement with the strip hole 1331.

[0064] When the telescopic device 131 drives the lifting plate 132 to rise and fall, the rollers or pins on the edge of the lifting plate 132 roll within the slotted hole 1331. Since the slotted hole 1331 is inclined relative to the vertical direction, when the lifting plate 132 moves upward, the rollers push the inner wall of the slotted hole 1331, causing the clamping ends of the two first grippers 133 to synchronously retract inward around the hinge end. Conversely, when the lifting plate 132 moves downward, the rollers or pins drive the slotted hole 1331 to move in the opposite direction, causing the clamping ends of the two first grippers 133 to synchronously open outward.

[0065] By cooperating with the above-mentioned strip hole 1331 and the lifting plate 132, the clamping and releasing action of the first gripper 133 in the horizontal direction is controlled by a vertical telescopic movement, which can ensure that the first pin 221 is clamped with uniform force and will not be deflected.

[0066] Furthermore, the first locking mechanism 130 also includes a base plate 134, which is fixed to the bottom of the housing 110. The hinged end of the first gripper 133 is hinged to the base plate 134. By setting an independent base plate 134, the hinged base of the first gripper 133 is made more stable, and the entire first locking mechanism 130 can be pre-assembled and debugged outside the housing 110 as an independent module before being installed into the housing 110, thus improving manufacturing and assembly efficiency.

[0067] As a further improvement to this embodiment, a first return spring 135 is sleeved on the piston rod of the first telescopic damping rod. One end of the first return spring 135 is connected to the lifting plate 132, and the other end is connected to the cylinder of the first telescopic damping rod. The first telescopic damping rod and the first return spring 135 provide additional damping force, making the first gripper 133 move smoothly during clamping or releasing, avoiding impact. In addition, when the first pin 221 is released, the telescopic rod of the first telescopic damping rod extends, and the first telescopic damping rod and the first return spring 135 rebound together, pushing the lifting plate 132 upward, thereby opening the first gripper 133.

[0068] Furthermore, a second telescopic damping rod 136 is provided between the lifting plate 132 and the base plate 134. The cylinder of the second telescopic damping rod 136 is connected to the lifting plate 132, and the piston rod of the second telescopic damping rod 136 is connected to the base plate 134. By providing two damping rods with opposite installation directions, additional damping force is provided, making the first gripper 133 move more smoothly during clamping or releasing, and avoiding impact.

[0069] Furthermore, to improve the locking reliability of the first locking mechanism 130 on the first pin 221, a first annular groove is provided on the first pin 221. Correspondingly, a protruding triangular plate 1332 is provided on the inner side of the clamping end of the first gripper 133. When the first gripper 133 is in the clamping state, the triangular plate 1332 is embedded in the first annular groove. Through the cooperation between the triangular plate 1332 and the annular groove, the first pin 221 is locked in the axial direction, preventing the first pin 221 from coming out of the first insertion hole 121.

[0070] In some embodiments, the second locking mechanism 240 is disposed inside the support platform 210. The second locking mechanism 240 is mainly used to lock the second pin 310 at the bottom of the quick-change worktable 300 into the second socket 211 on the support platform 210.

[0071] Specifically, refer to Figure 8 The second locking mechanism 240 includes a telescopic drive component 241, a fixed plate 242, a translation plate 243, and a second gripper 244.

[0072] The telescopic drive component 241 is horizontally disposed inside the support platform 210. Exemplarily, the telescopic drive component 241 can be a cylinder, a hydraulic cylinder, or an electric actuator. The cylinder body of the telescopic drive component 241 is fixedly connected to the interior of the support platform 210 via a connecting seat 245, ensuring that the telescopic drive component 241 does not shift during operation. The telescopic movable end of the telescopic drive component 241 extends or retracts horizontally.

[0073] The fixing plate 242 is vertically fixed inside the support platform 210, and the fixing plate 242 is positioned in front of the telescopic drive component 241. The translation plate 243 is installed at the telescopic movable end of the telescopic drive component 241. Under the drive of the telescopic drive component 241, the translation plate 243 can move closer to or away from the fixing plate 242 in the horizontal direction.

[0074] The second gripper 244 is disposed on both sides of the translation plate 243. Specifically, there are two second grippers 244, which are respectively disposed on the left and right sides of the translation plate 243. The middle part of the second gripper 244 is hinged to the fixed plate 242 via a hinge shaft. One end of the second gripper 244 is provided with an inclined extending stroke hole 2441, and a pin or roller is provided on the side of the translation plate 243, which rolls into the stroke hole 2441. The other end of the second gripper 244 extends to both sides of the second insertion hole 211.

[0075] When the piston rod of the telescopic drive component 241 extends, it pushes the translation plate 243 to move horizontally towards the fixed plate 242. Due to the inclined arrangement of the stroke hole 2441, during the horizontal movement, the rollers on the side of the translation plate 243 roll within the stroke hole 2441, forcing the two second grippers 244 to rotate around their central hinge axis. This causes the ends of the second grippers 244 to expand outwards synchronously, thereby releasing the second pin 310 inserted into the second insertion hole 211. Conversely, when the piston rod of the telescopic drive component 241 retracts, it drives the translation plate 243 to move horizontally away from the fixed plate 242, causing the ends of the second grippers 244 to retract inwards synchronously, thereby clamping the second pin 310.

[0076] Through the above structure, the horizontal movement of the telescopic drive component 241 is converted into the clamping and releasing movement of the second gripper 244. Unlike the vertical drive of the first locking mechanism 130, the second locking mechanism 240 adopts a horizontal drive, which allows the height dimension of the support platform 210 to be designed to be thinner, which is beneficial to lowering the center of gravity of the entire standard worktable and improving load-bearing stability.

[0077] Furthermore, the second pin 310 is provided with a second annular groove, and the end of the second gripper 244 is provided with a locking block 246 for engaging with the second annular groove. When the second gripper 244 is in the clamping state, the locking block 246 engages with the second annular groove, thereby locking the second pin 310 in the vertical direction. The engagement of the locking block 246 with the second annular groove prevents the quick-change worktable 300 from accidentally detaching from the support platform 210.

[0078] As a further improvement to this embodiment, the second locking mechanism 240 also includes a third telescopic damping rod 247. The cylinder of the third telescopic damping rod 247 is fixedly connected to the translation plate 243, and the telescopic rod of the third telescopic damping rod 247 is connected to the fixed plate 242.

[0079] Furthermore, a second return spring is fitted onto the telescopic rod of the third telescopic damping rod 247. One end of the second return spring is connected to the fixed plate 242, and the other end is connected to the cylinder of the third telescopic damping rod 247. When the piston rod of the telescopic drive component 241 retracts, the third telescopic damping rod 247 and the second return spring rebound together, assisting in pushing the translation plate 243 to move away from the fixed plate 242.

[0080] Meanwhile, the third telescopic damping rod 247 and the second return spring act as buffer elements, so that the second gripper 244 will not damage the surface of the second pin 310 due to excessive impact when clamping the second pin 310.

[0081] In one embodiment of this application, the quick-change worktable 300 has a rectangular structure, and the support platform 210 also has a rectangular structure. Four second locking mechanisms 240 are arranged inside the support platform 210, and the four second locking mechanisms 240 are respectively distributed in the four corner areas of the support platform 210. Correspondingly, the second insertion holes 211 are also distributed at the four corners of the top of the support platform 210. When the quick-change worktable 300 is placed on the support platform 210, the second insertion pins 310 at its four corners are simultaneously inserted into the corresponding second insertion holes 211, and are synchronously locked by the four second locking mechanisms 240.

[0082] The fourth water and electricity communication interface 320 is located at the bottom of the quick-change workbench 300. When the second pin 310 is inserted into the second socket 211 on the support platform 210, the fourth water and electricity communication interface 320 is exactly aligned with the third water and electricity communication interface 230 on the support platform 210.

[0083] In one embodiment of this application, the first water-electricity communication interface 140, the second water-electricity communication interface 222, the third water-electricity communication interface 230, and the fourth water-electricity communication interface 320 all adopt the same interface standard, that is, each water-electricity communication interface includes a water inlet, a power outlet, and a communication interface. Taking the first water-electricity communication interface 140 and the second water-electricity communication interface 222 as examples: the first water-electricity communication interface 140 is located on the lower side of the top plate of the fixed base 100, and it includes a first water inlet 141, a first power outlet 142, and a first communication interface 143. The second water-electricity communication interface 222 is located at the bottom of the supporting column 220, and it includes a second water inlet, a second power outlet, and a second communication interface.

[0084] When the support column 220 of the platform 200 is inserted into the fixed base 100, the first water and electricity communication interface 140 connects with the second water and electricity communication interface 222. At this time, the first water inlet interface 141 connects with the second water inlet interface to achieve water circuit connection; the first power inlet interface 142 connects with the second power inlet interface to achieve electrical signal connection; and the first communication interface 143 connects with the second communication interface to achieve communication connection.

[0085] Similarly, when the quick-change workbench 300 is placed on the support platform 210, the third water and electricity communication interface 230 connects with the fourth water and electricity communication interface 320. The cable between the second water and electricity communication interface 222 and the third water and electricity communication interface 230 passes through the cavity inside the support column 220 and the internal space of the support platform 220. Therefore, water, electricity and signals introduced from the fixed base 100 can be transmitted to the quick-change workbench 300 via the carrier 200, providing comprehensive energy and information supply for the objects to be processed on the quick-change workbench 300.

[0086] This embodiment integrates the water interface, power interface, and communication interface into a standardized interface. When the quick-change workbench 300 is placed on the carrier platform 200, all energy and signal connections are completed simultaneously, eliminating the need for any manual wiring operations. This not only significantly shortens product changeover time but also eliminates safety hazards caused by manual wiring errors.

[0087] It is understood that, in the embodiments of this application, the structure of the quick-change worktable 300 can be designed in various ways according to the specific shape and support points of the object to be processed. However, no matter how the upper structure of the quick-change worktable 300 changes, the layout and size of the second pin 310 and the fourth water and electricity communication interface 320 at its bottom remain strictly consistent.

[0088] In addition, chamfered guide structures are provided at the entrance of the first socket 121 and the entrance of the second socket 211 to assist the first pin 221 and the second pin 310 in being inserted smoothly.

[0089] Furthermore, a first guide sleeve 137 is provided on the inner side of the top plate 120 corresponding to the position of the first insertion hole 121, to further facilitate the insertion of the first insertion pin 221. Similarly, a second guide sleeve 248 is provided inside the support platform 210 corresponding to the position of the second insertion hole 211, to further facilitate the insertion of the second insertion pin 310.

[0090] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
