[0034] Specifically, the guiding mechanism includes a first guide plate 4 and a second guide plate 5. The first guide plate 4 and the second guide plate 5 are arranged between the two support seats 2. The first guide plate 4 is located to the right of the second guide plate 5.

The first guide plate 4 and the second guide plate 5 are adapted to the isostatic graphite 7.
[0035] Specifically, the first support mechanism includes a support rod 401 and a first spring 402. The same support rod 401 is fixedly installed between the first guide plate 4 and a support base 2.

[0037] Specifically, the gear mechanism includes a first rack plate 302, a gear 303, and a second rack plate 304. The gear 303 is fixedly sleeved on the rotating shaft 301. The first rack plate 302 is slidably installed on the inner wall of the bottom of the function box 3, and the second rack plate 304 is slidably installed on the inner wall of the top of the function box 3.

[0038] Specifically, the first guide plate 4 has a through hole 6, and the pressure block 204 is adapted to the through hole.
[0039] In this application, during operation, the motor 101 is first started, and its conveying shaft drives the conveying shaft 102 and the conveying roller 103 to rotate. The isostatic graphite 7 is conveyed at a constant speed via the toothed conveyor belt 104. The meshing of the teeth between the conveying roller 103 and the conveyor belt 104 prevents slippage, ensuring the workpiece smoothly enters the inspection area at a set interval. When the isostatic graphite 7 moves to the bottom of the function box 3, the position sensor is triggered, which activates the hydraulic cylinder 201 via the control system. Its output shaft pushes the pressure plate 202 to the left. The pressure plate 202 slides along the support rod 401 fixed to the left support seat, compressing the first spring 402 sleeved on the support rod. At this time, the pressure plate 202 drives the first rack plate 302 to slide at the bottom of the function box 3 via the first connecting plate 205. The first rack plate meshes with the gear 303, driving the gear 303 to rotate, which in turn drives the second rack plate 304 to slide in the opposite direction at the top of the function box. The second connecting plate 503 then... The two guide plates 5 move synchronously to the right, and the second guide plate 5 can apply a clamping force to the left side of the workpiece. At the same time, the pressure block 204 passes through the through hole 6 of the first guide plate 4 and acts perpendicularly on the surface of the isostatic graphite 7 to form a double-sided clamp. The pressure value transmitted by the pressure block 204 can be monitored in real time by the pressure sensor 203 and fed back to the control system. When the pressure reaches the preset detection value, the hydraulic cylinder 201 stops and holds the pressure for a set time to observe whether the workpiece is damaged. If the workpiece is normal, it is judged to be qualified. If the pressure drops suddenly (indicating damage), the system records that it is unqualified. This can achieve the purpose of testing the isostatic graphite 7, and further realize the purpose of automatically adjusting the spacing of the guide plates to adapt to workpieces of different sizes and improving work efficiency. After the test is completed, the hydraulic cylinder 201 retracts, and the first spring 402 and the second spring 502 release elastic potential energy respectively, so that the pressure plate 202 and the second guide plate 5 are reset, and the isostatic graphite 7 continues to be transported to the next station by the conveyor belt 104.
