A front screw and a rear screw are provided on the base; the wedge connecting plate is fixed on the front screw; the bushing is provided on the front screw and located on the upper side of the wedge connecting plate; the butterfly spring top plate is movably disposed on the front screw and the rear screw and located on the side of the bushing away from the wedge connecting plate; the butterfly spring sleeve plate is fixed on the front screw and the rear screw, and a track is provided in the middle of the butterfly spring sleeve plate; the top block is fixed on the butterfly spring top plate and abuts against the butterfly spring sleeve plate through a butterfly spring disposed in the track.

[0004] Furthermore, the device for verifying the fatigue strength of the wedge block further includes: a plurality of hexagonal nuts, one hexagonal nut fixed on each of the front screws, one hexagonal nut fixed on each of the rear screws, and the hexagonal nuts are abutting against the disc spring sleeve.

[0005] Furthermore, the top block is provided with an internal hexagonal head screw for engaging with the locking plate of the wedge block.

[0006] The technical solution of this utility model involves setting movable butterfly spring sleeves and top blocks on the front and rear screws, and using the butterfly springs for repositioning operations to achieve reciprocating motion of the wedge block, thereby testing the fatigue level of the wedge block.

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0013] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0014] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "several" or "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0017] This invention proposes a device for verifying the fatigue strength of a wedge block, aiming to design a testing device that can be used to detect the fatigue strength of a wedge block.

[0018] The device for verifying the fatigue strength of a wedge block proposed in this utility model will be described below in specific embodiments:

[0019] In the technical solution of this embodiment, such as Figure 1 , Figure 2 As shown, a device for verifying the fatigue strength of a wedge includes: a base 10, a wedge connecting plate 20, a bushing 30, a butterfly spring top plate 40, a butterfly spring sleeve plate 50, and a top block 60. A front screw 11 and a rear screw 12 are mounted on the base 10. The wedge connecting plate 20 is fixed to the front screw 11. The bushing 30 is mounted on the front screw 11 and located above the wedge connecting plate 20. The butterfly spring top plate 40 is movably mounted on the front screw 11 and the rear screw 12, and is located on the side of the bushing 30 away from the wedge connecting plate 20. The butterfly spring sleeve plate 50 is fixed to the front screw 11 and the rear screw 12, and a track is provided in the middle of the butterfly spring sleeve plate 50. The top block 60 is fixed to the butterfly spring top plate 40 and abuts against the butterfly spring sleeve plate 50 via a butterfly spring 51 disposed within the track.

[0020] Furthermore, the device for verifying the fatigue strength of the wedge block also includes: a plurality of hexagonal nuts 70, one hexagonal nut 70 fixed on each front screw 11, one hexagonal nut 70 fixed on each rear screw 12, and the hexagonal nuts 70 abutting against the disc spring sleeve 50.

[0021] Furthermore, the top block 60 is provided with an internal hexagonal head screw 61 for engaging with the locking plate of the wedge block.

[0022] Working principle: The air chamber and the wedge are respectively installed on the left and right sides of the wedge connecting plate 20 and are connected and fixed. The locking plate of the wedge is connected to the hexagonal head screw 61 on the top block 60. When the wedge moves, the two sides of the wedge push the top block 60 to move. The top block 60 drives the deflected spring top plate to move along the length direction of the front screw 11 and the rear screw 12, and compresses the deflected spring 51. When the wedge stops working, the reverse force of the deflected spring 51 pushes the top block 60 and the deflected spring sleeve 50 back to their original positions and acts on the wedge. This operation is repeated to verify the fatigue strength of the wedge.

[0023] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
