[0015] In the diagram: 1-base, 11-slide groove, 2-connecting plate, 21-bolt, 22-washer, 3-base plate, 4-first clamping member, 41-first base, 42-first fixing member, 43-second fixing member, 5-second clamping member, 51-second base, 52-third fixing plate, 53-fourth fixing plate, 54-protrusion, 6-third clamping member, 61-third base, 62-fifth fixing plate. Detailed Implementation
[0016] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.
[0017] Example:
[0018] like Figure 1 As shown, a torque testing fixture includes a base 1, a connecting plate 2, and a clamping assembly. The base 1 is located at the bottom of the connecting plate 2, and a sliding groove 11 is provided on the base 1. The fixture is connected to the test bench through the base 1 and is fixed by connecting to the clamp of the test bench through the sliding groove 11. The clamping assembly is located at the top of the connecting plate 2, and the connecting plate 2 is connected to the base 1 by bolts 21. A washer 22 is provided on the bolts 21.
[0019] The clamping assembly includes a base plate 3, a first clamping member 4, a second clamping member 5, and a third clamping member 6. The base plate 3 is mounted on the connecting plate 2 and is fastened to the connecting plate 2 by screws. The first clamping member 4, the second clamping member 5, and the third clamping member 6 are respectively mounted on the base plate 3. The first base 41, the second base 51, and the third base 61 are fastened to the base plate 3 by screws, facilitating the replacement of the positions of the first clamping member 4, the second clamping member 5, and the third clamping member 6 according to different models of torque test pieces.
[0020] The first clamping member 4 includes a first base 41, a first fixing member 42, and a second fixing member 43. The first base 41 is disposed on the base plate 3. The first fixing member 42 and the second fixing member 43 are sequentially disposed on the first base 41 from bottom to top and are connected and fastened to the first base 41 by screws. The first fixing member 42 protrudes from the side of the first base 41 near the second clamping member 5 and is used to fix the torque test piece. The width of the second fixing member 43 is smaller than the width of the first fixing member 42 and is used to limit the torque test piece.
[0021] The second clamping member 5 includes a second base 51, a third fixing plate 52 and a fourth fixing plate 53. The second base 51 is disposed on the base plate 3. The third fixing plate 52 and the fourth fixing plate 53 are disposed on the second base 51 from bottom to top and are connected and fastened to the second base 51 by screws. The third fixing plate 52 protrudes from the side of the second base 51 near the third clamping member 6 and is used to cooperate with the fifth fixing plate 62 to fix the torque test piece.
[0022] The fourth fixing plate 53 is provided with a protrusion 54, which is arc-shaped and is used to adapt to the corresponding groove shape of the torque test piece and to play a positioning role.
[0023] The third clamping member 6 includes a third base 61 and a fifth fixing plate 62. The fifth fixing plate 62 is disposed on the base plate 3 and on the third base 61, and is connected and fastened to the third base 61 by screws.
