Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-6 An automotive engine heat shield testing device mainly includes components such as a base 1, a movable plate 3, positioning wheels 4, a movable frame 6, an adjustment frame 7, and a lighting lamp 8. The base 1 is the basic support part of the entire testing device.

[0027] The base 1 has multiple rotating ports 2, each containing a transmission groove 11. A screw 14 is installed within each rotating port 2, with one end extending into the transmission groove 11. A motor 12 is installed within the transmission groove 11, and the motor 12 is connected to the screw 14 via a rotating mechanism. The motor 12 provides the power source for the entire device; its model can be selected according to actual needs to ensure sufficient power and stability.

[0028] Motor 12 is typically controlled by a specialized electrical control system to achieve precise speed and direction control. The installation location of motor 12 is carefully designed to ensure that it is not affected by external interference during operation, while also facilitating maintenance and repair.

[0029] The rotating mechanism consists of a drive gear 13 mounted on the output shaft of the motor 12 and a transmission gear 15 mounted on the screw 14. The transmission gear 15 meshes with the drive gear 13. When the motor 12 starts, the drive gear 13 drives the transmission gear 15 to rotate, thereby causing the screw 14 to rotate.

[0030] In order to ensure that the moving plate 3 moves stably on the screw rod 14 without rotating with the screw rod 14, a cross rod 16 is arranged in the rotating port 2 as a limiting mechanism. The cross rod 16 is parallel to the screw rod 14 and slides through the moving plate 3.

[0031] A heat dissipation net is also arranged on the base 1 in the transmission groove 11. The heat dissipation net is screwed in the transmission groove 11, can dissipate the heat generated by the motor 12 during operation in time, avoids overheating and damage of the motor 12, and prolongs the service life of the motor 12.

[0032] The moving plate 3 is sleeved on the screw rod 14 through a threaded sleeve and moves left and right with the rotation of the screw rod 14. The moving plate 3 is provided with four positioning wheels 4 which are distributed at equal intervals in the circumferential direction. The positioning wheels 4 are used to fix and support the automobile engine heat shield to be detected, so as to ensure that the heat shield remains stable during detection.

[0033] A protective ring is arranged on the positioning wheel 4. The protective ring is made of rubber and has anti-skid lines on the surface. The protective ring made of rubber can avoid damage caused by direct contact between the positioning wheel 4 and the heat shield, and the anti-skid lines can increase the friction force, further improving the stability of the heat shield.

[0034] The base 1 is provided with an annular groove 5, and the movable frame 6 is arranged in the annular groove 5. The movable frame 6 is provided with a movable cavity 17 inside, and the movable cavity 17 is provided with a sliding rod 19. The sliding rod 19 is provided with a limiting frame 18 through an elastic mechanism. The elastic mechanism is composed of a spring 20 sleeved outside the sliding rod 19, and the two ends of the spring 20 are connected with the two limiting frames 18 respectively. The vertical sectional view of the limiting frame 18 is U-shaped, and the vertical sectional view of the annular groove 5 is cross-shaped. This structure design enables the movable frame 6 to move and rotate stably in the annular groove 5, and the movable frame 6 cannot be separated from the annular groove 5 without external force.

[0035] The movable frame 6 is provided with an adjusting frame 7 through a mounting mechanism. The mounting mechanism includes mounting bolts 9 arranged on the adjusting frame 7 and a plurality of mounting holes 10 on the movable frame 6. The adjusting frame 7 is provided with a lighting lamp 8, which provides sufficient light for the detection of the heat shield. The lighting lamp 8 can be adjusted in angle and position according to the detection needs.

[0036] Through the movement and rotation of the movable frame 6 in the annular groove 5 and the adjustment of the mounting position of the adjusting frame 7 on the movable frame 6, the lighting lamp 8 can irradiate different parts of the heat shield, ensuring that the detection personnel can clearly observe the details of the heat shield.

[0037] The utility model discloses a detection device for the heat shield of automobile engine, which comprises a base, a movable plate, a rotating mechanism, a positioning wheel, a movable frame, an adjusting frame and a lighting lamp.

[0038] The above is only the preferred embodiment of the utility model, but the protection scope of the utility model is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
