Embodiment Construction

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] as attached figure 1 A femoral condyle fatigue test device tooling fixture of the present invention as shown includes a base, and the base 1 is fixedly connected with the fixing frame 2 by bolts, and is spaced left and right on the base 1 on the front and rear sides of the fixing frame 2 respectively. There are two elongated holes, such as Figure 4 shown. The bolts are screwed through the elongated holes on the threaded holes of the base of the femoral condyle fatigue testing machine. When it is not tightened, the whole tooling fixture can move left and right along the elongated hole. When tightening, the base 1 and the surface of the femoral condyle fatigue testing machine (existing device) closely fit, and the tooling fixture can be fixed on the femur due to the effect of friction. condyle fatigue testing machine.

Abstract

The invention discloses a tool clamp of a femoral condyle fatigue test device, which comprises a horizontal deflection angle adjusting block, the angle position between the horizontal deflection angle adjusting block and a fixed frame body can be adjusted by taking a horizontal deflection angle adjusting bolt as the center, and the angle position between the vertical deflection angle adjusting block and the horizontal deflection angle adjusting block can be adjusted by taking a vertical deflection angle adjusting bolt as the center. The locking fixing bolt can fix the horizontal deflection angle and the vertical deflection angle of the vertical deflection angle adjusting block and the horizontal deflection angle adjusting block relative to the base table of the femoral condyle fatigue testing machine and the horizontal direction and the vertical direction positions of the vertical deflection angle adjusting block and the horizontal deflection angle adjusting block relative to the base table, and the aim of locking the femoral condyle simulation test piece is achieved. The problem that the femoral condyle is difficult to install and position before a test due to irregularity of the shape of the femoral condyle can be effectively solved.

Description

technical field [0001] The invention relates to a tooling fixture of a fatigue test device, in particular to a tooling fixture of a femoral condyle fatigue test device. Background technique [0002] At present, the demand for artificial knee joint prostheses is increasing year by year. The mechanical testing of knee joint prostheses is mainly based on fatigue tests, which mainly focus on the tibial component and the femoral condyle. Due to the irregular shape of the femoral condyle, it is a technical problem to install and position it before the test, and the positioning deviation of the angles in all directions often leads to the lack of reference for the test results. There are currently no known femoral condyle fatigue test device fixtures. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a fixture for a femoral condyle fatigue test device which is helpful for realizing the precise positioning of the femoral condyle in the fatigue te...
