[0017] The present utility model provides a wedge mechanical efficiency detection mechanism, aiming to design a detection mechanism for detecting the mechanical efficiency of a wedge.

[0018] The wedge mechanical efficiency detection mechanism proposed by the present utility model will be described in the following specific embodiments:

[0019] In the technical solution of this embodiment, as Figure 1 shown, a wedge mechanical efficiency detection mechanism includes: a frame 10, two first pressure sensors 20, a lower sliding column 30 and a second pressure sensor 40. A cavity 11 is formed inside the frame 10; the two first pressure sensors 20 are respectively arranged on two opposite supporting cavity walls of the frame 10; the lower sliding column 30 is movably arranged on the frame 10, and one end is used to abut against the wedge 300; the second pressure sensor 40 is arranged at the other end of the sliding column and is used to abut against the push rod of the air chamber 200.

[0020] Further, the wedge mechanical efficiency detection mechanism further includes: a plurality of support columns 50, a connecting plate 60, an upper guide seat 70 and an upper sliding column 80. One ends of the plurality of support columns 50 are respectively fixed on the frame 10; the connecting plate 60 is connected to the other ends of the plurality of support columns 50; the upper guide seat 70 is arranged on the connecting plate 60; the upper sliding column 80 is movably arranged inside the upper guide seat 70, and the second pressure sensor 40 abuts against the push rod of the air chamber 200 through the upper sliding column 80.

[0021] Further, the lower sliding column 30 is movably connected to the frame 10 through a lower guide seat 90.

[0022] Further, the frame 10 includes: two bottom plates 12 and two side support plates 13. The tail end of the bottom plate 12 is connected to the head end of the side support plate 13 to form the frame 10 with the cavity 11.

[0023] Working principle: The wedge block 300 is placed in the cavity 11 of the frame 10 and connected to the lower guide seat 90 through bolts. The adjusting screws on both sides of the wedge block 300 are respectively abutted against the first pressure sensors 20. The lower sliding column 30, the second pressure sensor 40, and the upper sliding column 80 are connected together. The bottom of the lower sliding column 30 abuts against the input end of the wedge block 300 for inputting pressure. When the detection starts, the push rod of the air chamber 200 contacts the upper sliding column 80, and the force is transmitted to the input end of the wedge block 300 through the upper sliding column 80, the lower sliding column 30, and the second pressure sensor 40, prompting the mechanical structure of the wedge block 300 to move. The adjusting screws on both sides of the wedge block 300 respectively contact the two first pressure sensors 20. During the whole process, the second pressure sensor 40 between the upper sliding column 80 and the lower sliding column 30 detects the input pressure of the wedge block 300, and the data displayed by the first pressure sensor 20 is used as the output force. The ratio between the two forces is regarded as the mechanical efficiency.

[0024] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
