DETAILED DESCRIPTION

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] Example 1

[0020] The present application embodiment discloses a plate fixing tool suitable for a fatigue testing machine, referring to Figure 1 , Figure 2 and Figure 3 , including a mounting seat 1, on which a mounting groove 11 for vertically placing the end of a plate 10 is opened, and on the two inner side walls of the mounting groove 11, a first clamping block 2 and a second clamping block 3 for clamping both sides of the plate 10 are horizontally slidably connected, and the first clamping block 2 and the second clamping block 3 are both connected to a first driving member for driving themselves to move. A stud 5 is also welded on the mounting seat 1, and the mounting seat 1 is threadedly connected to the mounting part of the fatigue testing machine through the stud 5.

[0021] In the embodiment of the present application, two mounting seats 1 are vertically mounted opposite to each other on the mounting part of the fatigue testing machine, and then the plate 10 is placed between the two mounting seats 1, and the two ends of the plate 10 are respectively placed in the corresponding mounting grooves 11. Starting the corresponding first driving member can drive the first clamping block 2 and the second clamping block 3 to slide towards each other to clamp the end of the plate 10 together. Finally, starting the fatigue testing machine can stretch and compress the plate 10 to perform fatigue performance testing. The mounting seat 1 can be installed on the fatigue testing machine by means of threaded connection, and the end of the plate 10 can be clamped and fixed by the first clamping block 2 and the second clamping block 3, which has the effect of convenient operation and improved testing efficiency of the plate 10.

[0022] Specifically, the first driving member includes a screw rod 4, and first sliding grooves 12 for sliding the first clamping block 2 / second clamping block 3 are horizontally opened on both inner side walls of the mounting groove 11. First threaded holes communicating with the corresponding first sliding grooves 12 are horizontally opened on both side walls of the mounting seat 1, and the screw rod 4 is threadedly connected in the first threaded hole, and one end of the screw rod 4 is rotatably connected to the first clamping block 2 / second clamping block 3 on the corresponding side.

[0023] In the embodiment of the present application, rotating the screw rod 4 can drive the corresponding first clamping block 2 / second clamping block 3 to move along the depth direction of the slide groove, so that the first clamping block 2 and the second clamping block 3 can clamp the end of the plate 10 together.

[0024] Furthermore, a connecting piece is installed between the screw rod 4 and the corresponding first clamp block 2 / second clamp block 3. The connecting piece includes a connecting block 6, and a groove for accommodating the connecting block 6 is provided on one side of the first clamp block 2 / second clamp block 3 close to the screw rod 4. The connecting block 6 is rotatably arranged in the groove and is coaxially welded and fixed with the screw rod 4.

[0025] In the embodiment of the present application, the corresponding connecting blocks 6 can ensure that the first clamping block 2 and the second clamping block 3 will not separate from the corresponding screw rod 4 during the movement, thereby improving the stability of the first clamping block 2 and the second clamping block 3 during the movement.

[0026] In order to facilitate the staff to rotate the screw rod 4, a handle 7 is connected to one end of the screw rod 4 located outside the mounting seat 1. Specifically, the handle 7 can be a pin, and a mounting hole can be opened on the outer wall of the end of the screw rod 4 located outside the mounting seat 1. The pin is inserted into the mounting hole by interference fit. The staff can rotate the corresponding screw rod 4 by holding the pin.

[0027] Furthermore, a clamping member for clamping the narrow sides of the plate 10 is installed on the first clamping block 2, and the clamping member includes two clamping plates 8 slidably arranged on both sides of the first clamping block 2. One end of the clamping plate 8 is horizontally slidably connected to the first clamping block 2, and the other end of the clamping plate 8 is bent and extended to the inside of the installation groove 11 and is in active contact with the narrow side of the plate 10. The first clamping block 2 is installed with a second driving member for driving the clamping plate 8 to move.

[0028] In the embodiment of the present application, the first driving member is activated to allow the first clamping block 2 and the second clamping block 3 to clamp the two sides of the end of the plate 10 together. Since the plate 10 has a certain thickness, a gap is left between the first clamping block 2 and the second clamping block 3. Subsequently, the second driving member is activated to drive the clamping plates 8 on both sides to move into the gap in opposite directions to clamp the two narrow sides of the plate 10 together, further improving the clamping effect of the plate 10.

[0029] Specifically, the second driving member includes a fastening bolt 9. Second slide grooves 21 are provided on both sides of the first clamping block 2 along the width direction of the plate 10, the clamping plate 8 is slidably arranged in the corresponding second slide grooves 21, a second threaded hole 22 is provided on the inner bottom wall of the second slide groove 21, a through hole communicating with the second threaded hole 22 is provided on the clamping plate 8, and the fastening bolt 9 passes through the through hole and is threadedly connected in the second threaded hole 22.

[0030] In the embodiment of the present application, after the first clamping block 2 and the second clamping block 3 clamp the two sides of the end of the plate 10, rotating the fastening bolts 9 on both sides can drive the corresponding clamping plate 8 to move along the depth direction of the second slide groove 21 to jointly clamp the narrow sides of the plate 10.

[0031] The implementation principle of a plate fixing tool suitable for a fatigue testing machine in an embodiment of the present application is as follows: two mounting seats 1 are installed vertically opposite to each other on the mounting part of the fatigue testing machine, and then the plate 10 is placed between the two mounting seats 1, and the two ends of the plate 10 are respectively placed in the corresponding mounting grooves 11. By rotating the screws 4 on the two side walls of the mounting seat 1, the first clamping block 2 and the second clamping block 3 can be driven to slide towards each other to jointly clamp the ends of the plate 10. Finally, the fatigue testing machine is started to stretch and compress the plate 10 to perform a fatigue performance test on it. The mounting seat 1 can be installed on the fatigue testing machine by means of a threaded connection, and the ends of the plate 10 can be clamped and fixed by the first clamping block 2 and the second clamping block 3, which has the effect of convenient operation and improved testing efficiency of the plate 10.

[0032] Example 2

[0033] The difference between Example 2 and Example 1 is that the structure of the second driving member is different. Figure 4 The second driving member includes a bidirectional screw 91. A connecting hole 23 connected to the second slide grooves 21 on both sides is formed on the first clamping block 2 along the depth direction of the second slide groove 21. The bidirectional screw 91 is coaxially rotatably arranged in the connecting hole 23, and the two clamping plates 8 are respectively threadedly connected to the two threaded sections of the bidirectional screw 91.

[0034] In the embodiment of the present application, after inserting one end of the plate 10 into the corresponding installation groove 11, the bidirectional screw 91 can be rotated first to drive the two clamping plates 8 to slide synchronously in opposite directions, so that the plate 10 can be positioned at the center of the first clamping block 2, and then the two side screws 4 are rotated to make the first clamping block 2 and the second clamping block 3 jointly clamp the two sides of the end of the plate 10. The staff can rotate the bidirectional screw 91 with one hand to drive the two clamping plates 8 to move synchronously in opposite directions, which further improves the convenience of the plate 10 during installation.
