Through testing, potential design flaws can be identified, the excavator's vibration damping performance can be optimized, and its service life extended.

[0003] To verify whether the performance of excavator components meets the requirements, components such as the floor frame, cab, engine cover, hydraulic oil tank, and diesel tank are installed on the slewing platform, and the reliability of the components is verified through a whole vehicle test.

[0004] The shortcomings of existing technology are: The existing gantry fixtures (used to replace slewing platforms) can only be used on specific models (referring to specific excavator models) and are for single use only. After the fixtures are used, they are scrapped, resulting in poor reusability, high manufacturing costs, and cumbersome design. Utility Model Content

[0005] The purpose of this utility model is to provide a flexible tooling to solve the problems of existing gantry tooling (used to replace slewing platforms) which can only be used for specific machine models (referring to specific excavator models), and is disposable. After the tooling is used, it is scrapped, resulting in poor reusability, high manufacturing costs, and cumbersome design.

[0006] To achieve the above objectives, the present invention provides a flexible tooling, including a platform mainboard. The top surface of the platform mainboard is a stepped surface, which includes a first horizontal surface, a vertical surface, and a second horizontal surface connected sequentially from front to back. The height of the first horizontal surface is higher than the height of the second horizontal surface. A slide rail and several first threaded holes are provided on the second horizontal surface. The slide rail extends forward and backward, and the several first threaded holes are distributed sequentially forward and backward. A platform cover plate is provided above the second horizontal surface. The bottom surface of the platform cover plate is provided with a sliding groove and several second threaded holes. The sliding groove extends forward and backward, and the several second threaded holes are distributed sequentially forward and backward. The sliding groove and the slide rail slide in a forward and backward manner, and the first threaded holes and the second threaded holes are connected by bolts.

[0007] Furthermore, the first horizontal plane is at the same height as the top surface of the platform cover.

[0008] Furthermore, the second horizontal plane is provided with two slide rails distributed in the left and right directions, and the bottom surface of the platform cover is provided with two slide grooves distributed in the left and right directions, and the two slide grooves are respectively slidably engaged with the two slide rails in the front and back directions.

[0010] Furthermore, one of the slide rails has a plurality of first threaded holes distributed along the front and back on its outer side, another slide rail has a plurality of first threaded holes distributed along the front and back on its outer side, one of the slide grooves has a plurality of second threaded holes distributed along the front and back on its outer side, and another slide groove has a plurality of second threaded holes distributed along the front and back on its outer side.

[0011] Furthermore, the bottom surface of the platform motherboard is provided with two combined support structures distributed along the front and back, and the length of the combined support structures extends along the left and right sides.

[0012] Furthermore, the combined support structure includes a crossbeam extending horizontally, with mounting base plates at the bottom of the left and right ends of the crossbeam, and the two mounting base plates are located on the outside and below the platform motherboard.

[0013] Furthermore, the crossbeam is a U-shaped curved plate with its opening facing downwards. The front and rear edges of the end of the U-shaped curved plate are connected to the front and rear edges of the top surface of the mounting base plate by several ribs.

[0014] Furthermore, the mounting base plate is a rectangular plate, and the four included corners of the rectangular plate are respectively provided with connecting holes.

[0015] Furthermore, the area of ​​the first horizontal plane is larger than the area of ​​the second horizontal plane, the platform motherboard and the platform cover are rectangular plates, the edge of the first horizontal plane is provided with a number of mounting holes, and the middle of the first horizontal plane is provided with two through holes of different sizes.

[0016] In summary, the application of the technical solution of this utility model has the following beneficial effects: the structure of this utility model is reasonable. (1) By setting a platform motherboard, the top surface of the platform motherboard is a stepped surface. The stepped surface includes a first horizontal surface, a vertical surface, and a second horizontal surface connected from front to back. The height of the first horizontal surface is higher than the height of the second horizontal surface. Thus, the platform motherboard is designed as a stepped surface, with the front high and the back low. (2) By setting a slide rail and several first threaded holes on the second horizontal plane, the length of the slide rail extends along the front and back, and the several first threaded holes are distributed in sequence along the front and back. A platform cover plate is provided above the second horizontal plane, and a slide groove and several second threaded holes are provided on the bottom surface of the platform cover plate. The length of the slide groove extends along the front and back, and the several second threaded holes are distributed in sequence along the front and back. The slide groove and the slide rail slide in a sliding fit along the front and back, and the first threaded holes and the second threaded holes are connected by bolts. Thus, during the vibration test, the platform cover plate can be slid to the required position along the front and back direction according to the model of the machine (referring to the model of the excavator) of different lengths. Then, the platform cover plate is fixed by bolts. Then, one or more components such as the floor frame, cab, engine cover, hydraulic oil tank, and diesel tank can be installed on the flexible tooling. The flexible tooling (also called the bench tooling, used to replace the slewing platform) is installed on the vibration test bench. Finally, the reliability of the components is verified by the bench vibration test. Analysis shows that the structure of this utility model is simple. By adopting an adjustable bolt connection method, this structure can be used for bench vibration tests of different machine length models (referring to excavator models), which can improve the utilization rate of the bench, improve the reusability of bench tooling, and reduce R&D costs, thus solving the problems of low tooling reusability and poor interchangeability.
