[0038] Example:

[0039] See Figures 1 to 4 The embodiment of the present utility model discloses a gauge block 400 adjustment test device, which includes a test assembly 100, a first control rod 200 and a second control rod 300. The test assembly 100 includes two test seats 110 arranged opposite to each other, and the two test seats 110 are respectively connected to the first control rod 200 and the second control rod 300. The first control rod 200 and the second control rod 300 can move along the axial direction. When the first control rod 200 and the second control rod 300 move relative to each other, they can drive the two test seats 110 to move closer to or away from each other, thereby performing a tensile test. Each test seat 110 includes a slidable sliding seat 130, and the sliding seat 130 can be fixed to the test seat 110 using a second fixing rod 140. A first fixing rod 120 is also provided on the test seat 110. On the one hand, the first fixing rod 120 cooperates with the sliding seat 130 and the second fixing rod 140 to fix the gauge block 400. On the other hand, the first fixing rod 120 can apply tension to the gauge block 400 when moving with the test seat 110.

[0040] The gauge block 400 adjustment test device disclosed in this embodiment can install and fix various gauge blocks 400 by cooperating with the first fixing rod 120, the sliding seat 130 and the second fixing rod 140, so that one test device can be used for multiple gauge blocks 400, thereby achieving the purpose of cost saving.

[0041] See Figure 1 and Figure 2 The test assembly 100 includes two test seats 110 arranged opposite to each other. The two test seats 110 can be close to or far away from each other. When close to each other, it is convenient to install and remove the gauge block 400. When far away from each other, tension can be applied to the gauge block 400.

[0042] The test base 110 is provided with a first fixing rod 120, a sliding base 130, and a second fixing rod 140. The first fixing rod 120 is mounted on the first end of the test base 110, and the sliding base 130 is located at the second end of the test base 110. The sliding base 130 slides in cooperation with the test base 110, and the sliding direction of the sliding base 130 is perpendicular to the direction of the connecting line between the two test bases 110.

[0043] The second fixing rod 140 is installed on the sliding seat 130 . In this embodiment, the second fixing rod 140 can fix the sliding seat 130 to fix the position of the sliding seat 130 at a preset position of the test seat 110 , thereby fixing the gauge block 400 .

[0044] See Figure 3 In this embodiment, a guide groove 150 may be provided on the test socket 110. The guide groove 150 is provided in a direction from the second end to the first end of the test socket 110, and one end of the guide groove 150 extends to the end surface of the second end of the test socket 110. Of course, extending the guide groove 150 to the end surface of the second end of the test socket 110 is only one implementation of this embodiment. In other implementations, extending the guide groove 150 to the first end of the test socket 110 or extending both ends of the guide groove 150 to both ends of the test socket 110 is also possible.

[0045] In this embodiment, the second fixing rod 140 is engaged with the rotating rod of the sliding seat 130, and one end of the second fixing rod 140 extends into the guide slot 150. A nut 160 is disposed at the end of the second fixing rod 140 that extends into the guide slot 150, and the nut 160 slides in engagement with the guide slot 150. During use, rotating the second fixing rod 140 forward causes the nut 160 to press against the test seat 110, thereby securing the sliding seat 130 to the test seat 110. Rotating the second fixing rod 140 backward reduces the pressure between the nut 160 and the test seat 110, thereby allowing the sliding seat 130 to move back and forth on the test seat 110.

[0046] In this embodiment, in order to facilitate the installation of the nut 160, the guide groove 150 can be set to a shape such as a T-slot or a dovetail slot, in which the opening width is smaller than the bottom thereof.

[0047] See Figure 1 and Figure 4 The first control rod 200 and the second control rod 300 are respectively connected to the two test seats 110 in a one-to-one correspondence, and the first control rod 200 and the second control rod 300 can drive the two test seats 110 to move together when they move relative to each other.

[0048] The first control rod 200 and the second control rod 300 are movably connected. In this embodiment, the first control rod 200 and the second control rod 300 can be configured as a threaded connection. This allows for more precise control of the positions of the two test sockets 110, thereby ensuring more accurate test results. Of course, to ensure that the two test sockets 110 only undergo relative displacement and do not deflect when the first control rod 200 and the second control rod 300 rotate relative to each other, a guide rod can be provided between the two test sockets 110.

[0049] See Figure 5 The second control lever 300 includes a rotating portion 330 and a fixed portion 320. The fixed portion 320 is connected to the test socket 110. After the fixed portion 320 is connected to the test socket 110, the fixed portion 320 is fixed to the test socket 110. The cross-section of the fixed portion 320 can be configured as a non-circular shape such as a square or hexagonal shape to prevent the fixed portion 320 from rotating when the rotating portion 330 rotates. This ensures that the two test sockets 110 can move closer to or farther from each other when the second control lever 300 rotates relative to the first control lever 200. The rotating portion 330 is rotatably connected to the fixed portion 320, and the rotating portion 330 is threadedly connected to the first control lever 200.

[0050] See Figure 4 The first control rod 200 is provided with a threaded hole, a through hole 210 and a clearance groove 220. The through hole 210 is coaxially arranged with the threaded hole, and the clearance groove 220 is arranged on the side wall of the through hole 210. The first control rod 200 is also provided with a rotating piece 230 and an elastic member 240. The rotating piece 230 is located in the clearance groove 220, and the rotating piece 230 is rotatably connected to the first control rod 200. The two ends of the elastic member 240 are respectively connected to the rotating piece 230 and the first control rod 200. The elastic member 240 makes the rotating piece 230 have a tendency to rotate toward the through hole 210.

[0051] The elastic member 240 may be a spring or a torsion spring.

[0052] See Figure 4 A ratchet tooth 310 is provided on the rotating portion 330 at a position corresponding to the rotating piece 230. The ratchet tooth 310 is annular along the circumference of the rotating portion 330. When the rotating piece 230 enters the through hole 210, it engages with the ratchet tooth 310, allowing the rotating portion 330 to rotate only in the first direction relative to the first control rod 200. When the rotating portion 330 rotates in the first direction relative to the first control rod 200, the distance between the two test sockets 110 increases.

[0053] The ratchet teeth 310 cooperate with the rotating piece 230 to allow the rotating portion 330 to rotate only in the first direction. Because the force is mutual, when the test seat 110 applies an outward pulling force to the gauge block 400, it also applies an inward pulling force to the test seat 110. Therefore, when twisting the rotating portion 330 to rotate in the first direction, a large force needs to be applied. When the force is stopped, the ratchet teeth 310 cooperates with the rotating piece 230 to restrict the rotating portion 330, thereby maintaining the pulling force applied by the test seat 110 on the gauge block 400, thereby making the test results more accurate.

[0054] In this embodiment, the width of the ratchet 310 is greater than or equal to twice the width of the rotating piece 230 , so that when the rotating portion 330 rotates relative to the first control rod 200 , the rotating portion 330 can also move freely relative to the first control rod 200 .

[0055] In addition, a control block 250 and a control rope 260 are provided on the first control rod 200. The control block 250 is slidably connected to the first control rod 200, and the two ends of the control rope 260 are respectively connected to the control block 250 and the rotating piece 230. The sliding control block 250 allows the rotating piece 230 to enter or leave the through hole 210.

[0056] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
