Among them, the main detection part 4 is installed on the base 1, and the main detection part 4 is composed of a first guide rod 401, a first connecting block 402, an electric cylinder A403, a second guide rod 404, an electric cylinder B405, a second connecting block 406, a first mounting block 407, a coil spring A408, a first detection rod 409, a retaining ring A410, a coil spring B411, a second mounting block 412, a scale A413, a retaining ring B414 and a detection seat 415. Two first guide rods 401 are welded on the top surface of the base 1, and a first connecting block 402 is slid on the two first guide rods 401. An electric cylinder A403 is fixed on the top surface of the base 1, and the protruding end of the electric cylinder A403 is fixed on the bottom end surface of the first connecting block 402.

Among them, two second guide rods 404 are slid on the first connecting block 402, and a retaining ring B414 is welded on each second guide rod 404.

When the detection piece 3 is subjected to an extrusion test from top to bottom, the electric cylinder A403 is controlled to contract. Driven by the electric cylinder A403, the lower end of the first detection rod 409 contacts the top surface of the detection piece 3, and the electric cylinder A403 is continuously controlled to contract. At the same time, the top of the first mounting block 407 is observed to be aligned with the scale on the scale A413. When the scale is reached, the electric cylinder A403 is controlled to stop contracting, and at this time, it is observed whether the detection piece 3 is bent.

Among them, an auxiliary detection part 5 is installed on the base body 201, and the auxiliary detection part 5 is composed of a third guide rod 501, a force block 502, a plug-in block 503, a second detection rod 504, a spring rod 505, a threaded rod 506, a connecting rod 507 and a scale B508. A third guide rod 501 is welded to the outside of each base body 201, a force block 502 is welded at one end of the inner side of each third guide rod 501, and a spring rod 505 for resetting the force block 502 inward is welded to the inner side of each base body 201. A plug-in block 503 is slidably arranged on each third guide rod 501, and a second detection rod 504 with a cylindrical rod-shaped structure is plugged into each plug-in block 503. The two second detection rods 504 are located on the left and right sides of the detection piece 3. During use, the left and right limit of the detection piece 3 can be achieved through the two second detection rods 504, which facilitates the rapid centering of the detection piece 3.

Among them, each plug-in block 503 is threadedly connected to a threaded rod 506, and the two threaded rods 506 are respectively rotated on the two force-bearing blocks 502. The thread directions of the two threaded rods 506 are opposite. A connecting rod 507 with a hexagonal structure is welded to the right end of the left threaded rod 506, and the right end of the connecting rod 507 slides in the right threaded rod 506.

Among them, the inner sides of the two force blocks 502 are in contact, and the inner sides of the two force blocks 502 are both inclined; a detection seat 415 is welded on the second mounting block 412, and the lower half of the detection seat 415 is located between the two force blocks 502. When the detection seat 415 moves upward, it contacts the inclined parts of the two force blocks 502.

A scale B508 is fixed on the top end surface of the first mounting block 407 , and the bottom end surface of the scale B508 contacts the top end surface of the second connecting block 406 .

Working principle: When testing from top to bottom by squeezing, place the test piece 3 on the two first rollers 202, and control the electric cylinder A403 to contract. Driven by the electric cylinder A403, the lower end of the first test rod 409 contacts the top surface of the test piece 3, and the electric cylinder A403 is controlled to contract. At the same time, observe the alignment between the top of the first mounting block 407 and the scale on the scale A413. When the scale is reached, control the electric cylinder A403 to stop contracting, and observe whether the test piece 3 is bent.

When testing from back to front by squeezing, the electric cylinder B405 is controlled to extend. Under the push of the electric cylinder B405, the second connecting block 406, the second guide rod 404, the first mounting block 407, the first detection rod 409 and the detection seat 415 move forward until the detection seat 415 contacts the rear end surface of the detection member 3. The electric cylinder B405 is controlled to extend continuously. When the detection seat 415 squeezes the detection member 3, the spiral spring A408 is compressed. The indication of the second connecting block 406 on the scale B508 is observed. When the scale is reached, the electric cylinder B405 is controlled to stop extending. At this time, it is sufficient to observe whether the detection member 3 is bent.

When the tensile test is performed on the detection piece 3, the two second detection rods 504 are pulled out from the plug-in block 503, clamped on the connecting rod 507 with a wrench and rotated. Driven by the connecting rod 507, the two threaded rods 506 rotate synchronously. Driven by the two threaded rods 506, the two plug-in blocks 503 and the two second detection rods 504 move inward. When the sockets on the plug-in block 503 are aligned with the through holes on the detection piece 3, the two second detection rods 504 are passed through the two through holes on the detection piece 3 and plugged into the two plug-in blocks 503, and the electric cylinder A403 is controlled to extend. When the electric cylinder A403 extends, it drives the first connecting block 402 and the detection seat 415 to move upward. The detection seat 415 squeezes the inclined parts of the two force blocks 502, and the two force blocks 502 move outward synchronously. When the two force blocks 502 move outward, they drive the two threaded rods 506, the two plug-in blocks 503 and the two second detection rods 504 to move outward. Observe the top of the first mounting block 407 and the scale aligned with the scale A413. When the scale is reached, control the electric cylinder A403 to stop extending. At this time, observe whether the two circular holes on the detection piece 3 are damaged.

The above are only specific implementations of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and the protection scope of the present disclosure shall be based on the protection scope of the claims.
