[0001] This utility model belongs to the field of welding fixture technology, and in particular relates to a novel high-stability tooling quick-change base device. Background Technology

[0002] With technological advancements, the automotive manufacturing industry is experiencing rapid growth. As car models increase and production processes optimize, automated robotic production of automotive sheet metal parts has become the mainstream technology in the modern automotive industry. Small and medium-sized automotive sheet metal parts manufacturers, while possessing overall advantages, face economic disadvantages compared to larger manufacturers and lack the capacity for large-scale robotic production lines. Therefore, flexible production with robotic workstations has become the optimal choice for these manufacturers. When producing multi-state products flexibly, the accuracy of fixture positioning becomes crucial. To ensure product qualification rates, highly stable tooling quick-change mechanisms have received unprecedented attention.

[0003] Currently, there are few and simple quick-change modules for welding fixtures in robot workstations. They mostly rely on other mechanical assistance for switching, and the positioning accuracy is poor when switching frequently, with a high probability of mispositioning and loss of robot origin.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-4 As shown, this utility model is a novel high-stability tooling quick-change base device, including a fixed base 1, a welding fixture body 5 disposed above the fixed base 1, and a movable platform body 3 disposed between the top of the fixed base 1 and the bottom of the welding fixture body 5, and further including:

[0026] Bearing slides 2 are located on both sides of the top of the fixed base 1. Height locking mechanisms 10 are located near the center on both sides of the top of the fixed base 1. Position locking mechanisms 6 are located at the rear ends of both sides of the top of the fixed base 1. Front positioning mechanisms 4 are located at the front ends of both sides of the top of the fixed base 1. A coarse guide mechanism 7 is located at the center of the top of the fixed base 1, which is responsible for quickly switching the coarse guide for the moving platform's advancement. Precision guide mechanisms 12 are located on both sides of the rear ends of the top of the fixed base 1, which provide further precise guidance when advancement is about to be completed. Advancement position contact detection mechanisms 14 are located between the position locking mechanism 6 and the rear positioning mechanism 13 at the rear ends of the top of the fixed base 1. After advancement to the correct position, the advancement position contact detection mechanism 14 detects that advancement has reached the correct position. The release signal controls the locking mechanism 6 to lock the fast switching mobile platform. The middle position of the top two sides of the fixed base 1 is provided with a height positioning contact detection mechanism 11. After the height positioning contact detection mechanism 11 detects whether the position is in place, it releases a signal. The middle position of the rear two sides of the top of the fixed base 1 is provided with a rear positioning mechanism 13. When the front positioning mechanism 4 and the rear positioning mechanism 13 are activated, the fast switching mobile platform is precisely positioned and locked. When each contact detection mechanism detects the position signal, the height locking mechanism 10 is activated to fully control the fast switching mobile platform. The middle position of the top two sides of the fixed base 1 is provided with a moving wheel ground groove 9. The two sides of the front of the fixed base 1 are provided with guide grooves 8. The mobile platform body 3 can be positioned and guided to move onto the fixed base 1 through the guide grooves 8.

[0027] The movable wheels 15 are located at the four corners of the bottom of the main body 3 of the mobile platform. The main body 3 can be moved by the movable wheels 15. Front positioning seats 16 are located on both sides of the front end of the main body 3. Rear positioning seats 18 are located on both sides of the rear end of the main body 3 near the middle. A coarse guide seat 21 is located at the middle of the bottom of the main body 3. The coarse guide seat 21 cooperates with the coarse guide mechanism 7 to provide coarse guidance for the main body 3. Precision guide seats 17 are located on both sides of the rear end of the main body 3. The precision guide seats 17 cooperate with the precision guide mechanism 12 to precisely guide and position the main body 3 onto the fixed base 1. The rear positioning seats 18 on both sides of the rear end of the main body 3... A push-in contact 19 is provided between the 8 and the precision guide seat 17. A height positioning contact 22 is provided at the middle position of the bottom of both sides of the mobile platform body 3. The mobile platform body 3 can be accurately positioned by using the push-in contact 19 and the height positioning contact 22 in conjunction with the push-in contact detection mechanism 14 and the height positioning contact detection mechanism 11. A positioning locking seat 20 is provided at the rear end of both sides of the mobile platform body 3. After the mobile platform body 3 moves into position, the front positioning mechanism 4, the rear positioning mechanism 13, the positioning locking mechanism 6, and the height locking mechanism 10 lock the front positioning seat 16, the rear positioning seat 18, the positioning locking seat 20, and the mobile platform body 3 to fix and quickly replace the platform.

[0028] Working principle: During operation, the mobile platform body 3 is pushed to the top of the fixed base 1 by the moving wheels 15. The guide groove 8 limits the position of the moving wheels 15. Simultaneously, the coarse guiding mechanism 7 and coarse guiding seat 21 quickly switch the coarse guiding of the mobile platform's movement. During the pushing of the mobile platform body 3, the bearing slide 2 assists in the pushing process. When the pushing is almost complete, the coarse guiding mechanism 12 and precision guiding seat 17 provide further precise guidance. After the pushing is completed, the pushing-in contact detection mechanism 14 detects that the pushing-in contact 19 has reached the correct position and releases a signal. When the activation locking mechanism 6 engages, it locks the main body 3 of the mobile platform. At this time, the moving wheels 15 are located within the wheel-to-ground groove 9, quickly switching the mobile platform off the ground. The height positioning contact detection mechanism 11 detects that the height positioning contact 22 is in place and releases a signal. The front positioning mechanism 4 and the rear positioning mechanism 13 then engage, locking the front positioning seat 16 and the rear positioning seat 18. Simultaneously, the aforementioned locking mechanisms are triggered, and the contact detection mechanisms detect the activation of the positioning signal. The height locking mechanism 10 then operates, fully controlling the main body 3 of the mobile platform. Releasing the complete locking signal completes the switching operation of the mobile platform. When switching welding fixtures, pressing the release button releases the locking mechanisms, allowing the moving wheels 15 to push out and quickly switch the mobile platform.

[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
