Description

Technical Field

[0001] The utility model relates to the technical field of automobile inspection tools, in particular to an automobile door guide rail inspection tool. Background Art

[0002] Generally, the door guide rail is an important part of the door. In the past, the inspection of the door guide rail was carried out by testing the data of the pallets at different positions. Due to the differences in the material of the pallets and the measurement, measurement errors would occur. The measurement auxiliary tooling was complex, inefficient and had high errors.

[0003] A Chinese patent discloses a vehicle door guide rail inspection fixture and vehicle (authorization publication number CN205002698U). This patented technology utilizes a receiving space on the fixture body to accommodate the door guide rail body, with the door guide rail's mounting portion extending from an opening in the receiving space. A first detection mechanism then detects the hole position of the mounting portion; a second detection device detects the size of the guide rail body and the mounting portion, thereby enabling inspection of the door guide rail. The fixture is compact, easy to operate, and low-cost, improving efficiency and ensuring high accuracy and reliability in door guide rail inspection.

[0004] However, it has certain disadvantages: after completing the inspection of one automobile door rail, the debris and impurities left on the automobile door rail will adhere to the inspection tool body. When the next door rail is inspected, these residues will interfere with the normal operation of the inspection tool, resulting in increased errors in the test results and reduced test accuracy. In addition, the accumulation of debris and impurities will cause wear on the contact surface or moving parts of the inspection tool, thereby affecting the performance of the inspection tool. Over time, this wear will gradually increase, resulting in a significant reduction in the accuracy and service life of the inspection tool. Utility Model Content

DETAILED DESCRIPTION

[0021] See also Figure 1 In an embodiment of the present utility model, a vehicle door guide rail inspection fixture includes a base plate 1, a first inspection platform 2 is installed on the upper surface of the base plate 1, a storage groove 3 is opened on the upper surface of the first inspection platform 2, and a vehicle door guide rail 4 is placed inside the storage groove 3. A clamp 5 is installed on the upper surface of the first inspection platform 2 on the left side of the storage groove 3, and a second inspection platform 6 is installed on the right side surface of the first inspection platform 2. The right side surface of the vehicle door guide rail 4 is in contact with the left side surface of the second inspection platform 6. A detection pin 7 is movably connected to the interior of the second inspection platform 6;

[0022] The clamp 5 is manually pulled to press the upper surface of the automobile door guide rail 4 to fix it;

[0023] The car door guide rail 4 is placed in the storage slot 3. If the car door guide rail 4 fits in the slot and its right side surface fits the second testing platform 6, it means that the size of the car door guide rail 4 is appropriate.

[0024] The detection pin 7 can be inserted into the hole of the automobile door guide rail 4 to detect the size and specific position of the hole to be detected, ensuring the accuracy of the position of each hole on the door guide rail, thereby ensuring the assembly accuracy and stability of the entire guide rail; in addition to basic size and position detection, the detection pin 7 can also be used to detect technical indicators such as roundness and coaxiality of the automobile door guide rail 4.

[0025] exist Figures 1 to 3 Middle: A blowing pipe 8 is installed above the second testing table 6, and a blowing hole 9 is opened on the lower surface of the blowing pipe 8, and a connecting pipe 10 is connected to the front surface of the blowing pipe 8, and one end of the connecting pipe 10 is provided with a blowing mechanism 11, and the blowing mechanism 11 includes a fan 12, and a first wind cover 13 is installed at the lower end of the fan 12. The lower end of the first wind cover 13 is installed on the upper surface of the base plate 1, and a filter plate 14 is connected to the one side surface of the first wind cover 13. A second wind cover 15 is installed at the upper end of the fan 12, and one end of the connecting pipe 10 is connected to the upper surface of the second wind cover 15;

[0026] The fan 12 is used to draw air from the outside, so that the air flow is ejected through the blowing hole 9 to clean the surface of the storage slot 3 and the bottom plate 1, thereby preventing the debris and impurities left after the inspection of the current automobile door guide rail 4 from affecting the inspection accuracy of the next automobile door guide rail 4, and also preventing the accumulation of debris and impurities from wearing the contact surface or moving parts of the inspection tool, which will reduce the accuracy and service life of the inspection tool in the long run;

[0027] The filter plate 14 filters the dust in the air to prevent the dust from entering the fan 12;
