In actual use, the staff places the armrest box at the center of the fixed seat 304, and then rotates the positive and negative screw rods 305. The rotation of the positive and negative screw rods 305 drives the limit plates 306 at both ends to move synchronously towards each other, and the limit plates 306 at both ends move towards each other to achieve the positioning and clamping of the armrest box. When the armrest box is clamped and fixed, start the hydraulic cylinder 205. Through the drive of the hydraulic cylinder 205, the piston end drives the first test block 206 to move downward, and through the compaction of the first test block 206, the pressure resistance test of the armrest box cover is achieved.

[0026] By cooperating with the multiple parts in the set limit assembly 300, different types of armrest box covers can be limited and fixed. In actual use, the set limit assembly 300, compared with the traditional positioning cavity, can adapt to armrest box covers of different models and sizes, ensuring that various types of armrest box covers can be accurately fixed and tested, thereby improving the versatility of the testing machine.

[0027] Second embodiment:

[0028] like Figure 2-3 As shown, a slider is provided under the fixed seat 304, and the slider passes through the threaded rod 302 and is installed in the sliding groove provided by the adjustment seat 301 and the positioning seat 303. The fixed seat 304 moves within the travel range set in the sliding groove of the adjustment seat 301 and the positioning seat 303 through the threaded rod 302. When it is necessary to detect the armrest box cover in different directions, the staff adjusts the threaded rod 302, and the rotation of the threaded rod 302 drives the fixed seat 304 and the limit plate 306 to move forward and backward. The front and rear adjustment of the armrest box cover is achieved through the front and rear movement of the fixed seat 304 and the limit plate 306. Combined with the use of the first test block 206, the armrest box cover can be detected in different directions.

[0032] By using the limit plate 306 in conjunction with the rubber plate 307, the armrest box cover can be stably clamped. In actual use, since the rubber plate 307 has good elasticity and softness, it can reduce damage to the surface of the armrest box during the clamping process and maintain its appearance quality. At the same time, the rubber plate 307 can increase friction and provide better grip, thereby ensuring the stability of the armrest box cover during the test and preventing sliding or displacement.

[0033] Fourth embodiment:

[0034] like Figure 3 As shown, positioning holes are symmetrically provided at the end of the limiting plate 306, and the rubber plate 307 is detachably fixed in the mounting groove of the limiting plate 306 through the positioning bolt 308. In actual use, the rubber plate 307 is engaged with the mounting groove of the limiting plate 306 so that the two are completely fitted together. At this time, the rubber plate 307 can be firmly installed through the positioning bolt 308.

[0035] By using the positioning bolt 308 in conjunction with the limiting plate 306 , the rubber plate 307 can be quickly installed and fixed. In addition, the positioning bolt 308 can be used to make the rubber plate 307 more firmly installed, thus avoiding displacement during the clamping process.

In actual use, the staff starts the hydraulic cylinder 205, and the second test block 207 is moved downward by the drive of the hydraulic cylinder 205. At this time, with the use of the threaded rod 302, the upper end face and the side of the second test block 207 are pressed against the armrest box cover, and then the threaded rod 302 is adjusted to drive the armrest box cover to be squeezed toward the side of the second test block 207, thereby completing the inspection of the side of the armrest box cover.

[0041] By using the shaft seat 203 in cooperation with the fixing bolt 204, the hydraulic cylinder 205 can be quickly installed and disassembled. Meanwhile, by using the second test block 207 in cooperation with the threaded rod 302, the side pressure test of the armrest box cover can be performed.

[0042] Working principle: The staff places the armrest box at the center of the fixed seat 304, and then rotates the positive and negative threaded rods 305. The rotation of the positive and negative threaded rods 305 drives the limit plates 306 at both ends to move synchronously in opposite directions. The limit plates 306 at both ends move in opposite directions to achieve the positioning and clamping of the armrest box. When the armrest box is clamped and fixed, the hydraulic cylinder 205 is started. The piston end drives the first test block 206 to move downward through the drive of the hydraulic cylinder 205. The compaction of the first test block 206 is achieved. For the pressure resistance test of the armrest box cover, it is also necessary to perform a pressure test on the edge. In actual use, the staff starts the hydraulic cylinder 205, and the second test block 207 is moved downward by the drive of the hydraulic cylinder 205. At this time, with the use of the threaded rod 302, the upper end face and the side of the second test block 207 are pressed against the armrest box cover, and then the threaded rod 302 is adjusted to drive the armrest box cover to be squeezed toward the side of the second test block 207, thereby completing the inspection of the side of the armrest box cover.
