Problems solved by technology

[0003] Most of the traditional drop impact test platforms are single-track or double-track, which has the problems of simple structure and inaccurate punch constraints, resulting in unstable mass falling; in addition, the design of the traditional structure has certain restrictions on the shape of the punch. The scope of use is limited; moreover, the height of the mass block in the traditional rope-drawn impact device is constrained by the gear slot, and the lifting and release of the mass block are operated manually. It is difficult to accurately set the height of the mass block, which makes the impact speed difficult to be accurate.
Most of the traditional drop impact test process is tedious and time-consuming, and there are certain safety hazards in the device, which makes the test data not accurate enough and cannot meet the requirements of simulation calculation

Embodiment Construction

[0020] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0021] Such as Figure 1~6 As shown, the present invention mainly includes a base 1 on which four base supports 2 are connected by bolts, and the four base supports 2 are evenly distributed at the four corners of the base 1 . The front end of each base bracket 2 is connected with a guide rail bracket 4 , and every two adjacent guide rail brackets 4 are connected by a plurality of transverse connecting rods 11 , and four guide rail supports 4 are connected into a rectangular body through the transverse connecting rods 11 .

[0022] The base 1 is provided with a two-dimensional coordinate line, and the origin of the two-dimensional coordinate line is set directly below the punch assembly 5 .

[0023] The space (length, width, height) between the base bracket 2 and the base 1 should be large enough to meet the structural impact test requirements of certa...

Abstract

The invention relates to a dropping impact test platform, particularly relates to an impact-resistant performance test used for testing the level of material and parts and components used for automobiles, and belongs to the technical field of mechanical test. The dropping impact test platform comprises a pedestal. Four pedestal supports are connected on the pedestal via bolts. One guide rail support is connected at the front end of each pedestal support. The internal side of each guide rail support is provided with a slide guide rail from the top to the bottom. The internal side of each guide rail support is provided with a punch assembly which is slidably connected with the slide guide rail arranged at the internal side of the guide rail support. The top part of each guide rail support is provided with a guide wheel assembly. The external side of the lower end of each guide rail support is provided with a numerical control release motor. Wight and height of the punch assembly can be accurately set so that accuracy of the test result can be guaranteed; and various impact test requirements for the level of the material, the parts and components and products can be completed so that test efficiency is high and test safety is guaranteed.

Description

technical field [0001] The invention relates to a drop impact test platform, in particular to an impact resistance test for testing materials and parts used in automobiles, and belongs to the technical field of mechanical testing. Background technique [0002] In the design and processing of automotive materials and parts, many materials, parts and products are required to meet certain impact resistance properties, such as energy-absorbing foam pads for carpets, coat racks, ceilings, door sheet metal and Airbags etc. Therefore, an impact test platform that can meet the needs of materials, components and product levels is needed to complete the relevant impact resistance test. [0003] Most of the traditional drop impact test platforms are single-track or double-track, which has the problems of simple structure and inaccurate punch constraints, resulting in unstable mass falling; in addition, the design of the traditional structure has certain restrictions on the shape of th...
