[0026] In the specific implementation process, such as Figures 1 - 8As shown in the figure, a pressure test fixture for base processing is characterized in that it includes an installation base plate 1. Multiple positioning components and multiple extrusion components 2 for limiting the side of the base are provided on the top of the installation base plate 1. The positioning components include a first cylinder 3, a movable part, a universal ball 4, and a protection part. The bottom of the first cylinder 3 is fixedly connected to the top of the installation base plate 1. One end of the movable part is movably connected to the push rod of the first cylinder 3. An installation groove 5 for installing the universal ball 4 is provided at the other end of the movable part. The universal ball 4 is located inside the installation groove 5. A fixing plate 6 is fixedly provided on the outside of the universal ball 4. A limiting groove 7 for installing the protection part is provided on the side of the fixing plate 6 away from the universal ball 4;

[0027] The protection part includes a protection pad 8 and a limiting block 9. One side of the protection pad 8 is fixedly connected to one side of the limiting block 9. Positioning rods 10 are provided on both sides of the limiting block 9. The limiting block 9 is located inside the limiting groove 7 opened on the fixing plate 6. And clamping grooves 11 matching the positioning rods 10 are provided on both sides inside the limiting groove 7. A fixing rod 12 is also provided at the end of the movable part away from the first cylinder 3. And a through hole 13 is provided at the center of the fixing rod 12. The inner side of the through hole 13 is inclined, and the outside of the universal ball 4 is in fit with the inner side of the through hole 13. The movable part includes a movable rod 14 and two connecting rods 15. A groove 16 is provided at one end of the movable rod 14. The push rod of the first cylinder 3 is located inside the groove 16. And the push rod of the first cylinder 3 is rotationally connected to the movable rod 14 through a movable column 17. The two connecting rods 15 are respectively located on both sides of the movable rod 14. And both ends of the connecting rod 15 are rotationally connected to the movable rod 14 and the top of the first cylinder 3 through two connecting columns 18 respectively. Multiple pressing components for limiting the top of the base are also provided on the top of the installation base plate 1. The pressing components include a second cylinder 19 and a pressing rod 20. The bottom of the second cylinder 19 is fixedly connected to the top of the installation base plate 1. The top of the pressing rod 20 is fixedly connected to the push rod of the second cylinder 19. A placing column 21 for placing the base is also provided on the top of the installation base plate 1;

[0028] When the first cylinder 3 is started, since the movable rod 14 is rotationally connected to the push rod of the first cylinder 3 through the movable column 17, and both ends of the connecting rod 15 are rotationally connected to the movable rod 14 and the top of the first cylinder 3 through two connecting columns 18 respectively, when the push rod of the first cylinder 3 moves up and down, the movable rod 14 will rotate along the center of the connecting column 18 connected to the movable rod 14, so that the side of the protection pad 8 away from the limiting block 9 is in fit with the outside of the base. When the outside of the base contacted by the protection pad 8 is inclined or uneven, the protection pad 8 will adjust its own angle through the universal ball 4, so that the protection pad 8 can better fit with the outside of the base, increasing the contact area between the two and improving the friction between the protection pad 8 and the base.

[0029] The working principle provided by the present utility model is as follows: Start cylinder 1. Since the movable rod 14 is rotationally connected to the push rod of cylinder 1 through the movable column 17, and both ends of the connecting rod 15 are rotationally connected to the movable rod 14 and the top of cylinder 1 through two connecting columns 18 respectively, when the push rod of cylinder 1 moves up and down, it will cause the movable rod 14 to rotate along the center of the connecting column 18 connected to the movable rod 14, so that the side of the protective pad 8 away from the limiting block 9 fits against the outer side of the base. When the outer side of the base contacted by the protective pad 8 is inclined or uneven, the protective pad 8 will adjust its own angle through the universal ball 4, so that the protective pad 8 can better fit against the outer side of the base, increasing the contact area between the two and improving the friction between the protective pad 8 and the base;

[0030] Meanwhile, through the setting of the protective pad 8, it can also provide a certain degree of protection for the outer side of the base, ensuring that the base will not be damaged prematurely due to excessive pressure. The multiple pressing components 2 provided on the top of the mounting base plate 1 can further limit and fix the side of the base;

[0031] And since the positioning rod 10 has a certain elasticity, the limiting block 9 and the protective pad 8 can be taken out from the limiting groove 7 opened on one side of the fixing plate 6 by pulling, so as to maintain or replace them. The positioning rod 10 provided on both sides of the limiting block 9 can be fixed through the card slots 11 opened on both sides inside the limiting groove 7, so that the protective pad 8 can be stably stuck on one side of the fixing plate 6;

[0032] Through the through hole 13 provided at the center of the fixing rod 12, the universal ball 4 can be limited to prevent the universal ball 4 from falling off from the installation groove 5;

[0033] Through the placement column 21 provided on the top of the mounting base plate 1, it is used to place the base to be processed. Meanwhile, by starting cylinder 2, the pressing rod 20 is driven to move towards the top of the base, and the top of the base is limited by the pressing rod 20, further improving the stability during the processing of the base.
