Embodiment

[0020] see Figure 1 to Figure 3 , the present invention provides a kind of technical scheme:

[0021] A hundred grid test device, comprising a test table 1, an X-Y-Z drive assembly 2 and a suspension scratch assembly 3, wherein:

[0022] The X-Y-Z drive assembly 2 is set on the test bench 1, wherein the X-Y-Z drive assembly 2 is composed of two cross-arranged linear drive assemblies and hydraulic cylinders, wherein the horizontal linear drive assembly is connected with the longitudinal linear drive assembly. The hydraulic cylinder is connected with the execution part of the horizontal linear drive assembly, wherein the three-degree-of-freedom drive assembly is a conventional technical means for those skilled in the art, and will not be repeated here. The suspension scratch assembly 3 is arranged on the X-Y-Z drive assembly 2. On the execution part, then the X-Y-Z drive assembly 2 can drive the suspension scratch assembly 3 to move along the three directions of X-Y-Z;

Abstract

The invention provides a cross-cut testing device which comprises a testing table, an X-Y-Z driving assembly and a suspension scratching assembly, a suspension frame of the suspension scratching assembly is connected with an execution part of the X-Y-Z driving assembly, a linear bearing is vertically installed on the suspension frame, a cross-cut cutter is installed in the linear bearing in a matched mode, and a lever pressure applying assembly is arranged at the top of the cross-cut cutter. And the suspension traction assembly pulls the cross-cut knife. The lever pressing assembly is in the zero-gravity suspension state when no weight is placed, the acting force of the cross-cut knife on the workpiece can be adjusted by changing the normal pressure generated by the lever pressing assembly on the cross-cut knife, the acting force of the cross-cut knife on the workpiece comes from the lever pressing assembly, and the normal pressure generated by the lever pressing assembly is constant. Therefore, the acting force of the cross-cut knife on the workpiece can be accurately controlled, the cross-cut knife can freely move in the vertical direction, the normal force is fixed, and the position of the cross-cut knife does not need to be adjusted when a scratch test is carried out on the non-planar workpiece.

Description

technical field [0001] The invention relates to the field of bone implant testing, in particular to a 100 grid testing device. Background technique [0002] Orthopedic implants mainly include bone joint implants and joint implants, such as bone plates, bone screws, intramedullary nails, spinal internal fixation implants, artificial joints, etc. According to the different parts of use, it can be divided into trauma, spine, joint and others, and bone implants need to be scratched during actual use. [0003] Publication number CN108548777B provides an automatic one-hundred-grid testing device for corrosion-resistant workpieces, which relates to the field of tooling aids, and includes a hundred-grid knife, a machine base and a controller. The interior of the machine base is provided with a moving mechanism, and the upper end of the machine base is fixed A bracket is connected, the upper end of the moving mechanism is fixedly connected with a placing mechanism, the center positi...
