For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0023] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0024] Example 1

[0025] like Figure 1As shown, a switchable oil tank box fixture workbench includes a work surface 1, a robot body 2 and a positioning fixture 3 for fixing the position of the oil tank box. The robot body 2 is installed on the work surface 1, and the positioning fixture 3 is detachably installed on the work surface 1. The work surface 1 is also provided with a support block 11 for supporting the oil tank box, and a positioning structure 31 is provided on the positioning fixture. The positioning fixture 3 is detachably installed on the work surface 1. When different oil tank boxes need to be processed, it is only necessary to select a matching positioning fixture 3, install it on the work surface 1, and then place the oil tank box on the corresponding positioning fixture 3. The positioning fixture 3 is provided with a positioning structure 31, and the positioning structure 31 can cooperate with the process hole on the oil tank box to fix the position of the oil tank box in the horizontal direction. Since the bottom surface of the oil tank box is a relatively complex curved surface structure, if it is placed directly on the work surface 1, it is possible that the oil tank box will tilt due to uneven force during the processing, resulting in poor processing and certain safety hazards. If the work surface 1 is designed as a curved surface that fits the bottom surface of the fuel tank box, the processing difficulty of the work surface 1 will increase, and it cannot be adapted to fuel tank boxes with curved surface structures of other shapes. Different fuel tank boxes need to be designed with different work surfaces 1, which will greatly increase the production cost of the work surface. In order to adapt to more different fuel tank boxes, the work surface 1 should not be in surface contact with the fuel tank box. Therefore, a support block 11 is provided on the work surface, and the bottom surface of the fuel tank box placed on the positioning fixture 2 is abutted against the support block, and the surface contact between the fuel tank box and the work surface 1 is changed to point contact with the support block 11, so as to fix the vertical position of the fuel tank box. Then the robot body is started to perform processing operations on the fuel tank box.

[0026] like Figure 1 As shown, there are multiple positioning fixtures 3 arranged on the work surface 1, and the robot body 2 is arranged between the positioning fixtures 3. When the switchable fuel tank box fixture workbench is working, one positioning fixture 3 can be placed on a fuel tank. Multiple positioning fixtures 3 on the work surface 1 can enable the switchable fuel tank box fixture workbench to continuously process multiple fuel tanks at one time, thereby improving the working efficiency of the switchable fuel tank box fixture workbench. The robot body 2 is arranged between the positioning fixtures 3 to ensure that the distance between the robot body 2 and each different positioning fixture 3 is the same, so that when the robot body 2 processes fuel tanks on positioning fixtures 3 located at different positions, the program does not need to be greatly changed.

[0027] like Figure 2As shown, the positioning structure 31 is a positioning pin, and there are multiple positioning pins. The position of the positioning pin matches the position of the process hole of the fuel tank box; the positioning fixture 3 is provided with a groove structure 32 that runs from the top to the bottom, and the support block 11 is accommodated in the groove structure 32. The position of the process hole of the fuel tank box is an important feature that distinguishes different fuel tank boxes. Since the process hole is a structure designed by the fuel tank box itself, the fuel tank box is positioned using this structure, and there is no need to design a positioning structure specifically on the fuel tank box, which reduces the processing cost of the fuel tank box and avoids damage to the fuel tank box. The positioning structure 31 is a positioning pin. When the fuel tank box is placed, the positioning pin is inserted into the process hole of the fuel tank box. When the fuel tank box is offset on the horizontal plane, the process hole of the fuel tank box will conflict with the positioning pin, thereby limiting the offset of the fuel tank box. At the same time, the bottom surface of the fuel tank box is placed on the support block 11, so that the position of the fuel tank box in the vertical direction is determined. Since the support block 11 is disposed on the work surface 1, the positioning fixture 3 is also installed on the work surface 1. If the support block 11 needs to contact the oil tank box, the support block 11 needs to pass through the positioning fixture 3. Therefore, the positioning fixture 3 is provided with a groove structure 32 that runs from the top to the bottom, so that the support block 11 can pass through the positioning fixture 3.

[0028] like Figure 2 As shown, the positioning fixture 3 is provided with a locking bolt 33, which is arranged at the diagonal position of the positioning fixture 3, and the locking bolt 33 is threadedly connected to the work surface 1. The positioning fixture 3 itself abuts against the work surface 1 to fix it on one surface. A single locking bolt 33 can fix the positioning fixture 3 at a certain position on the work surface 1, and the locking bolt 33 is arranged at the diagonal position of the positioning fixture 3, so that the positioning fixture 3 will not rotate while fixing the positioning fixture 3 at a certain position on the work surface 1, and the positioning fixture 3 is completely fixed on the work surface 1. The locking bolt 33 can be directly loosened and tightened manually without the need to use other tools, which is convenient for disassembly and replacement of the positioning fixture 3.

[0029] Example 2

[0030] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 2As shown, a guide block 12 is also provided on the work surface 1, and there are multiple guide blocks 12, each guide block 12 is fixed around the positioning fixture 3, and a downwardly inclined guide surface is provided on the guide block 12, and the guide surface faces the positioning fixture 3. When the positioning fixture 3 is quickly replaced, how to efficiently find the installation position of the positioning fixture 3 is a key factor affecting the replacement of the positioning fixture 3. The guide block 12 is used to assist the position of the positioning fixture 3 on the work surface. There are multiple guide blocks 12, which are fixed around the preset position of the positioning fixture 3 on the work surface 1. When installing the positioning fixture 3, it is only necessary to ensure that the positioning fixture 3 is located between the guide blocks 12, and the positioning fixture 3 can be roughly determined to be in the preset position. In the process of quickly replacing the positioning fixture 3, it is difficult for workers to align the position of the guide block 3 in a short time, and the guide block 12 may conflict with the positioning fixture 3, resulting in the positioning fixture 3 being installed unsmoothly, affecting the installation efficiency of the positioning fixture 3. To solve this problem, a downwardly inclined guide surface is provided on the guide block 12, and the guide surface faces the positioning fixture 3. When placing the positioning fixture 3, if the positioning fixture 3 conflicts with the guide block 12, since the guide block 12 is provided with a downward inclined guide surface, when the positioning fixture 3 contacts the guide surface, under the combined action of the supporting force of the guide surface, the gravity of the positioning fixture 3 itself and the downward force when the positioning fixture 3 is manually placed, the positioning fixture 3 slides downward along the guide surface, and finally slides to the preset position between the guide blocks 12, that is, the positioning fixture 3 is installed.

[0031] like Figure 2 As shown, switching handles 34 are also provided at both ends of the upper surface of the positioning fixture 3. Since the positioning fixture 3 is a plate-like structure, it is inconvenient to take it, which is not conducive to the operation of quickly replacing the positioning fixture 3, especially when the positioning fixture 3 is picked up from the work surface 1, due to the lack of an ideal force point for lifting the positioning fixture 3, it is difficult to pick it up manually, which reduces the efficiency of replacing the positioning fixture 3. Therefore, it is necessary to design a structure that is easy to take the positioning fixture 3. The switching handles 34 are provided at both ends of the positioning fixture 3 to provide convenient force points for workers to carry the positioning fixture 3. When replacing the positioning fixture 3, the worker only needs to grab the switching handles 34 at both ends of the positioning fixture 3 with both hands to conveniently lift or put down the switching handles 34.

[0032] like Figure 2As shown, the support block 11 is magnetic. Since the switchable tank box fixture workbench uses the robot body 2 to process the tank box, whether the tank box is fixed stably directly affects the processing quality and product quality. Since the support block 11 has a limited contact surface with the tank box, it is difficult to ensure that the tank box will not move relative to the support block 11 if only relying on the friction between the contact surface between the support block 11 and the bottom surface of the tank box. Therefore, in addition to the gravity of the tank box 11 itself, other forces are required to fix the tank box on the support block 11 to ensure the stability of the position of the tank box. According to the physical property that the material of the tank box can be attracted by magnetic substances, the support block 11 is set to be magnetic. When the tank box is placed on the support block 11, the tank box is attracted by the magnetism of the support block 11 and is fixed on the support block 11 and is difficult to move, thereby achieving the fixation of the position of the tank box and ensuring the quality of the tank box processed by the robot body 2.

[0033] Example 3

[0034] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 1 As shown, a placement cabinet 4 for placing positioning fixtures 3 of different specifications is provided below the work surface 1. Since different fuel tank boxes have different specifications, they require matching positioning fixtures 3 to ensure that the fuel tank box can be fixed after being placed to ensure the accuracy of the subsequent processing of the robot body 2, so a large number of positioning fixtures 3 are required. When switching the positioning fixture 3, in order to improve the switching efficiency, the positioning fixture 3 should be placed closer to the work surface 1 to reduce the time required to take and place the positioning fixture 3 back and forth, improve the working efficiency of the positioning fixture 3, and reduce the labor load of the workers. A placement cabinet 4 is provided below the work surface 1 for placing different positioning fixtures 3. When replacing the positioning fixture 3, the worker does not need to move, but only needs to take out the positioning fixture 3 in the placement cabinet 4 below the work surface 1 and place it on the work surface 1, which makes the worker's operation simple and convenient and reduces the worker's labor load.

[0035] like Figure 1 As shown, the work surface 1 is surrounded by an enclosure structure 5. When the robot body 1 processes the oil tank box, it is necessary to ensure that there are no other structures in the space near the robot body 2 that hinder the movement of the robot body 2 to avoid interference with the work of the robot body 2 and potential safety hazards. The work surface 1 is surrounded by an enclosure structure 5, which surrounds the work surface 1 and the robot body 2 to form a relatively independent space, isolating it from the outside world, and preventing other objects from entering the enclosure structure 5 during the working process of the robot body 2 to interfere with the robot body 2, thereby ensuring the safety of the processing process.

[0036] like Figure 1As shown, an operating table 6 for operating the robot body 2 is also provided outside the switchable oil tank box and the glue box workbench, and the operating table 6 is electrically connected to the robot body 2. When the robot body 2 is used for work, the worker only needs to control the robot body 2 on the operating table 6, and does not need to be close to the switchable oil tank box and the glue box workbench.

[0037] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here.
