Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Refer to the appendix of the instruction manual Figs. 1-3 As can be seen, this application specifically designs a special tooling for a brake cylinder function testing bench, including a placement groove 2 set on the workbench 1 of the function testing bench body. A brake cylinder base 3 is movably inserted into the placement groove 2. Insertion limiting components are symmetrically arranged on both sides of the brake cylinder base 3. A drive control component is set at the bottom of the placement groove 2. The two moving ends of the drive control component are respectively connected to the insertion limiting components. The insertion limiting component includes rectangular notches 4 opened on both sides of the placement groove 2. Sliding grooves 5 are symmetrically arranged on both sides of the rectangular notches 4. Sliding blocks 6 are slidably inserted into the sliding grooves 5. A T-shaped locking block 7 is set at one end of the sliding block 6. The T-shaped locking block 7 is engaged in the limiting grooves on both sides of the brake cylinder base 3. A fixing pin 8 is set at the bottom of the sliding block 6. The fixing pin 8 is rotatably engaged with the moving end of the drive control component. The brake cylinder base 3 is provided with a support groove 9 matching the brake cylinder to be tested and bolt positioning holes 10. The brake cylinder to be tested is assembled and connected to the brake cylinder base 3 by fixing bolts 11. In use, the matching brake cylinder is selected according to the model of the brake cylinder to be tested. The base 3 is used to assemble the brake cylinder to be tested onto the brake cylinder base 3 via fixing bolts 11. The brake cylinder base 3 is placed into the placement slot 2, and the limiting slots on both sides of the brake cylinder base 3 are aligned with the T-shaped locking blocks 7. The drive control component is activated to push the sliders 20 on both sides to slide along the slide groove 5, thereby inserting the T-shaped locking blocks 7 into the limiting slots, thus achieving the limiting and locking of the brake cylinder base 3. Functional testing is performed in conjunction with the accessories on the functional testing bench. Based on the existing functional testing bench 1, the workbench 1 is improved. By using the plug-in limiting component, the limiting and locking of different models of brake cylinders can be achieved, thereby completing the corresponding functional testing operations. When using it, only the matching brake cylinder base 3 needs to be selected according to the model of the brake cylinder to be tested for assembly. Moreover, during the continuous testing of the same model of brake cylinder, it is not necessary to remove the brake cylinder base 3, which can greatly improve the efficiency of continuous testing operations. The structure is compact, the operation is convenient, and the brake cylinder base 3 can be locked with one key. The installation and disassembly are extremely convenient.

[0017] In the specific implementation process, the above-mentioned drive control component includes a fixed shaft 12 set on the lower end face of the placement groove 2. A swing arm 13 is rotatably mounted on the fixed shaft 12. Both ends of the swing arm 13 are rotatably connected to a pull rod 14. One end of the pull rod 14 is rotatably engaged with a fixed pin 8. A pneumatic control component is connected to one side of the swing arm 13. The pneumatic control component includes a mounting base 15 set on the bottom surface of the placement groove 2. The mounting base 15 is hinged to the fixed end of the pneumatic telescopic rod 16. The movable end of the pneumatic telescopic rod 16 is rotatably connected to the side of the swing arm 13. In use, controlling the movable end of the pneumatic telescopic rod 16 to retract can pull the swing arm 13 to deflect. The deflection of the swing arm 13 can then drive the pull rod 14 to move. During the movement of the pull rod 14, the fixed pin 8 pulls the sliding block 6 to slide along the slide groove 5, so that the T-shaped locking block 7 at the top of the sliding block 6 is inserted into the limiting slots on both sides of the brake cylinder base 3 to achieve one-key locking. Similarly, controlling the movable end of the pneumatic telescopic rod 16 to expand can unlock it.

One end of the adjusting bolt 23 is rotatably engaged with the side wall of the slider 20. In use, the limiting boss 17 at the front of the brake cylinder base 3 is inserted into the limiting slot 18, and then the adjusting bolt 23 is rotated. The adjusting bolt 23 pushes the slider 20 and the top block 21 to push the brake cylinder base 3 to move slowly forward. When the limiting slots on both sides of the brake cylinder base 3 are aligned with the T-shaped locking block 7, the adjusting bolt 23 is stopped, and the T-shaped locking block 7 is inserted into the limiting slots on both sides of the brake cylinder base 3. The structure is compact, the adjustment is convenient, and there is no need for the operator to repeatedly align it.
