Description

Technical Field

[0001] The utility model relates to the technical field of guide plate detection, in particular to a guide plate detection jig for an automobile air intake duct. Background Art

[0002] In order to reduce the lift generated by cars when driving at high speeds, car designers have made improvements to the appearance of cars, tilting the entire car body forward and downward to generate downward pressure on the front wheels, changing the rear end of the car to a short and flat shape to reduce the negative air pressure from the roof to the rear to prevent the rear wheels from floating, and installing a downward-tilted connecting plate under the front bumper of the car. The connecting plate is integrated with the front skirt of the car body, and a suitable air inlet is opened in the middle to increase the air flow and reduce the air pressure under the car. This connecting plate is called a deflector; after the deflector is produced, in order to test the deflector effect of the deflector, it is necessary to perform a simulated deflection test on it and measure whether the test data is qualified.

[0003] When the current detection device detects the deflector, it is necessary to first fix the deflector, then blow air towards the front of the deflector, and detect the wind velocity at the rear of the deflector. After the deflector is fixed, the angle position cannot be adjusted, so it is not convenient to align the deflector at various positions around the deflector for blowing detection, which will cause errors in the detection data. Therefore, a deflector detection fixture for an automobile air intake is proposed. Utility Model Content

[0027] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0028] like Figures 1 to 4As shown, this embodiment proposes a deflector detection fixture for an automobile air intake duct, comprising a base 1, a box 2 arranged on the top of the base 1, and a U-shaped frame 3 rotatably arranged on the top of the box 2, and also comprising a fixing component, an intermittent component and a detection component. The fixing component is arranged on both sides of the U-shaped frame 3, and is used to clamp and fix the deflector. The intermittent component comprises a motor 4 arranged on the inner bottom wall of the box 2, a rotating column 5 rotatably arranged on the top of the box 2, an incomplete gear 401 arranged at the output end of the motor 4, and a complete gear 501 arranged on the rotating column 5 located inside the box 2 and meshing with the incomplete gear 401. The top of the rotating column 5 is connected to the bottom of the U-shaped frame 3. The detection components are arranged on both sides of the box 2, and are used to detect the fixed deflector.

[0029] The guide plate to be inspected is fixed on the U-shaped frame 3 through the fixing component, and then the guide plate is subjected to the blowing inspection through the set inspection component. At the same time, the starting motor 4 drives the incomplete gear 401 to rotate. When the incomplete gear 401 rotates to the toothed side and contacts the complete gear 501, the complete gear 501 and the rotating column 5 will be driven to rotate. When the incomplete gear 401 rotates to the toothless side and contacts the complete gear 501, the complete gear 501 and the rotating column 5 will gradually stop under the action of gravity, so that the U-shaped frame 3 on the rotating column 5 can be driven to rotate intermittently, and then the guide plate can be driven to rotate intermittently, which is convenient for the inspection component to perform blowing inspection in different directions, thereby improving the accuracy of the inspection data.

[0030] Among them, an anti-slip cover 201 is provided on the top of the box body 2, and the rotating column 5 extends toward both sides through the anti-slip cover 201; when the toothed side of the incomplete gear 401 separates from the complete gear 501, the anti-slip cover 201 can increase the friction with the rotating column 5, allowing the rotating column 5 to stop quickly, thereby preventing the rotating column 5 from rotating too much and affecting the guide plate detection.

[0031] like Figure 1 and Figure 5 As shown, as a preferred embodiment, based on the above method, further, the fixing assembly includes a screw rod 6 threadedly arranged on the side walls of both ends of the U-shaped frame 3 and a clamping block 7 rotatably arranged on the screw-in end of the screw rod 6 located on the inner side of the U-shaped frame 3;

[0032] The screw-in end of the screw rod 6 is provided with a mounting block 601, and the side wall of the clamping block 7 is provided with a movable block 701, and the movable block 701 is rotatably arranged on the inner wall of the mounting block 601;

[0033] The guide plate is placed between the two clamping blocks 7, and then the two screw rods 6 are rotated to drive the two clamping blocks 7 to gradually approach and abut against the two ends of the guide plate, so that the guide plate can be clamped and fixed, and through the cooperation of the mounting block 601 and the movable block 701, the clamping block 7 can be rotated freely on the screw rod 6. When the clamping block 7 contacts the guide plate, it can rotate to facilitate stable fitting with the irregular side wall of the guide plate, further improving the stability of the guide plate fixation.

[0034] It should be noted that the side wall of the U-shaped frame 3 is provided with a support assembly, which includes a slide groove 301 opened on the side wall of the U-shaped frame 3, a slide plate 8 slidably arranged on the inner wall of the slide groove 301, a spring 801 arranged between the slide plate 8 and the inner bottom wall of the slide groove 301, and a support plate 9 arranged on the top of the slide plate 8;

[0035] When fixing the guide plate, the guide plate can be placed on the support plate 9, and then the support plate 9 can be moved up and down to adjust the position of the guide plate. After the two ends of the guide plate are clamped and fixed, the bottom of the guide plate can also be supported by the support plate 9, further improving the stability of the guide plate fixation.

[0036] In addition, a placement frame 13 is provided at the bottom of the U-shaped frame 3; some guide plates that need to be tested can be temporarily placed through the placement frame 13.

[0037] like Figures 1 to 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the detection component includes a fixing frame 10 symmetrically arranged on the side walls of both ends of the box body 2, a fan 11 arranged on the side wall of one fixing frame 10, an air flow detector 12 arranged on the side wall of another fixing frame 10, and an exhaust frame 1101 arranged at the output end of the fan 11, and the exhaust frame 1101 and the air flow detector 12 are at the same horizontal height;

[0038] After the guide plate is fixed, start the fan 11 to blow air toward the front side of the guide plate through the exhaust frame 1101. After the wind passes through the guide plate, the airflow velocity passing through the guide plate is detected by the airflow detector 12, so as to evaluate whether the air guiding effect of the guide plate is qualified based on the data.

[0039] Specifically, the fixing frame 10 includes a fixing frame 1001, a fixing plate 1002 slidably arranged inside the fixing frame 1001, and a bolt 1003 threadedly arranged on the outer wall of the fixing frame 1001. A positioning groove matching the bolt 1003 is provided on the surface of the fixing plate 1002; by pulling the fixing plate 1002 up and down, the height of the fan 11 and the airflow detector 12 can be adjusted, and then the bolt 1003 is rotated to pass through the fixing frame 1001 and abut against the positioning groove on the surface of the fixing plate 1002, so that the fixing frame 10 with the adjusted height can be locked, thereby facilitating the detection of guide plates at different heights.

[0040] The working principle of the utility model is as follows: the guide plate is placed between the two clamping blocks 7, and then the two screw rods 6 are rotated to drive the two clamping blocks 7 to gradually approach and abut against the two ends of the guide plate, so that the guide plate can be clamped and fixed, and through the cooperation of the mounting block 601 and the movable block 701, the clamping block 7 can be rotated freely on the screw rod 6. When the clamping block 7 contacts the guide plate, it can rotate to facilitate stable fit with the irregular side wall of the guide plate, further improving the stability of the guide plate fixation; then the fan 11 is started to blow air toward the front side of the guide plate through the exhaust frame 1101. After the wind passes through the guide plate, the airflow velocity passing through the guide plate is measured by the airflow detector 12. The detection is carried out, so as to evaluate whether the wind guiding effect of the guide plate is qualified according to the data; at the same time, the starting motor 4 works to drive the incomplete gear 401 to rotate. When the incomplete gear 401 rotates to the side with teeth and contacts with the complete gear 501, it will drive the complete gear 501 and the rotating column 5 to rotate. When the incomplete gear 401 rotates to the side without teeth and contacts with the complete gear 501, the complete gear 501 and the rotating column 5 will gradually stop under the action of gravity, so that the U-shaped frame 3 on the rotating column 5 can be driven to rotate intermittently, and then the guide plate can be driven to rotate intermittently, which is convenient for the detection component to perform wind blowing detection in different directions, thereby improving the accuracy of the detection data.

[0041] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
