[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-Figure 2As shown, a clamping mechanism for continuous silicon nitride fiber filaments includes two clamping modules arranged opposite to each other, each clamping module includes a base 10, a fixing column 11, a fixing clamp plate 20, a movable clamp plate 30, a fixing plate 40 and an adjusting bolt 50.

[0029] The fixing column 11 is integrally connected or fixedly connected to one side of the base 10. A connecting hole 111 is provided on the fixing column 11. The fixing column 11 is used to connect the clamping module to the traction tensile machine. In this embodiment, a cylindrical pin is used in conjunction with the connecting hole 111 to connect the clamping module to the traction tensile machine. Other fixed connection methods may also be used.

[0030] The fixed column 11 of this embodiment is connected with a knurled nut 60, which is used to correct or compensate for the gap between the traction tensile machine and the fixed column 11 to prevent the connection hole 111 from deforming after the clamping mechanism is used for a long time, thereby reducing the maintenance cost and working hours of the clamping mechanism.

[0031] The fixed clamp plate 20 is fixedly connected to the upper end surface of the base 10 by bolt locking, and the fixed plate 40 is fixedly connected to the base 10, and the fixed plate 40 is located above the fixed clamp plate 20. In this embodiment, two connecting columns 70 are also included, one end of each connecting column 70 is fixedly connected to the base 10, and the other end of each connecting column 70 is fixedly connected to the fixing plate 40, and the fixing plate 40 is fixedly connected to the base 10 through the connecting column 70. In this embodiment, a threaded connection or a fixed connection method of a bolt and a nut can be used to achieve the connection between the connecting column 70 and the fixing plate 40 and the base 10.

[0032] The fixed plate 40 is provided with a threaded through hole, and the adjusting bolt 50 is threadedly connected to the threaded through hole. The end of the adjusting bolt 50 close to the fixed nipper plate 20 is fixedly connected to the movable nipper plate 30, and the movable nipper plate 30 is driven to rise or fall by the adjusting bolt 50. In this embodiment, the movable nipper plate 30 is provided with two guide holes, and the two connecting columns 70 respectively pass through the corresponding guide holes in a one-to-one correspondence, and the connecting columns 70 also play a guiding role.

[0033] A handle 80 is connected to one end of the adjusting bolt 50 away from the fixing plate 40 to facilitate the rotation of the adjusting bolt 50 .

[0034] A plurality of evenly distributed clamping grooves a are provided on one side of the movable clamp plate 30 facing the fixed clamp plate 20 and / or on one side of the fixed clamp plate 20 facing the movable clamp plate 30. The longitudinal section of the clamping groove a is trapezoidal. By providing the clamping groove a, the silicon nitride fiber filaments are more securely restrained and not easily pulled out.

[0035] To sum up, when the clamping mechanism is in use, the clamping module is first fixed to a conventional traction tensile testing machine through the fixing column 11, and then the two ends of the silicon nitride fiber filament are clamped one by one on the corresponding clamping modules, and then the two clamping modules are driven to move in opposite directions by the traction tensile testing machine to test the tensile strength of the silicon nitride fiber filament. The clamping mechanism is easy and simple to operate. The movable clamp plate 30 is driven to rise or fall by rotating the adjusting bolt 50 through the handle 80, which is convenient for clamping the silicon nitride fiber filament, and effectively improves the detection efficiency and accuracy.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
