[0029] It is worth noting that the inspection fixture for automobile bumper decoration in the present application is an existing structure, in which the decoration will be placed inside the simulated placement block 11. By using the detection bolt and the detection block inside the simulated placement block 11, the flatness, position and other important positions and dimensions of the decoration are detected. By setting the protective seat 3 and several protective components on the lower side of the placement frame 2, it is convenient to provide protective support for the lower side of the decoration to avoid the occurrence of breakage during the detection of the decoration. By using the hydraulic cylinder 18 and the pressure-resistant detection plate 19, the surface of the decoration can be squeezed to realize the pressure resistance detection of the decoration by the detection device. The driving slide rail 14 and the bracket body support the position of the hydraulic cylinder 18, which is convenient for automatically moving the hydraulic cylinder 18 to different positions of the decoration to realize the detection of the surfaces of the decoration at different positions.

[0030] like Figure 1 and Figure 3As shown, the protection component includes a main groove 4 and a sub-groove 5 which are arranged on the protection seat 3, a buffer spring 6 which is arranged in the main groove 4, a plurality of damping pads 8 which are arranged on the buffer spring 6, and a buffer tube 7 which is sleeved on the top of the buffer spring 6 and slides with the main groove 4. The main groove 4 and the sub-groove 5 are filled with hydraulic oil, wherein several protection components are evenly arranged on the protection seat 3, and a through opening is opened on the surface of the placement rack 2. When the detected decorative part is deformed and passes through the through opening, the decorative part will squeeze the protection component, and the buffer tube 7 can be pressed toward the main groove 4 to cause deformation. The hydraulic oil in the main groove 4 is pressed into the sub-groove 5, and the diameter of the damping pad 8 is the same as the inner diameter of the buffer tube 7. The telescopic buffer spring 6 will drive the friction between the damping pad 8 and the buffer tube 7 and the inner wall of the main groove 4, which can weaken the pressure on the buffer tube 7 and protect the lower end of the decorative part.

When the buffer tube 7 is pressed into the main groove 4, the hydraulic oil in the main groove 4 will flow into the auxiliary groove 5. When there is no external pressure on the top of the buffer tube 7, the buffer spring 6 elastically resets, and the hydraulic oil flows back to the main groove 4, weakening the external pressure on the buffer tube 7. The rubber pad 9 can increase the elastic friction between the buffer tube 7 and the pressure-applying object, avoid the displacement of the decorative parts, and increase the detection stability of the decorative parts.

The slide seat can drive the electric push rod 15 to move to the left or right on the placement rack 2.

[0036] like Figure 1 and Figure 2 As shown, a plurality of pressure sensors 20 connected to the electrical control cabinet 10 are provided at the lower end of the pressure detection plate 19. By applying the pressure detection technology of the existing sensors, the hydraulic cylinder 18 squeezes the pressure detection plate 19 downward to detect the pressure resistance of the decorative parts. The connection between the pressure detection plate 19 and the electrical control cabinet 10 can transmit the detection data of the pressure sensor 20 to the base 1 in the electrical control cabinet 10 for display, so as to facilitate the quality screening of the pressure resistance of the decorative parts.

The electric push rod 15 is moved to a suitable position, and then the electric control cabinet 10 is used to control the telescopic length of the electric push rod 15, and the hydraulic cylinder 18 is raised and lowered to the upper side of the decorative part. Then the hydraulic cylinder 18 is used to fit the pressure resistance detection plate 19 to the upper surface of the decorative part. Through the continuous squeezing of the hydraulic cylinder 18, the pressure sensor 20 can detect the pressure on the surface of the decorative part in real time, and then transmit the detection data to the electric control cabinet 10. The electric control cabinet 10 uses a pressure display module to display the detection data on the display screen 12, and can read the data of the surface pressure resistance of the decorative part, which is convenient for the staff to screen the quality of the decorative parts, increase the pressure resistance detection function of the inspection tool, reduce the pressure resistance detection steps of the decorative parts, reduce the detection cost, and increase the comprehensiveness of the inspection tool and decorative parts detection.
