Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts inspection tools, in particular to an automobile air deflector assembly inspection tool. Background Art

[0002] The quality of air deflectors significantly impacts a vehicle's driving speed. Currently, deflector quality testing is primarily performed after the injection molding and hole-drilling processes, where the deflectors are mounted on a test bench and their surfaces inspected using a test fixture. However, during the actual injection molding process, deflectors, freshly removed from the mold, are still in a hot, soft state when placed on the test fixture. This can easily cause deformation due to thermal expansion and contraction, leading to quality deviations. Therefore, it is necessary to design a test fixture capable of fine-tuning the deflector's profile after injection molding. Utility Model Content

[0003] The purpose of the utility model is to provide a vehicle air deflector assembly inspection tool to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a vehicle air deflector assembly inspection fixture, comprising a test platform for fixing the deflector, the test platform being provided with a track, a plurality of fixing seats being slidably installed on the track along the length direction, the fixing seat being provided with a mounting groove, a screw being provided in the mounting groove, one end of the screw passing through the top of the fixing seat being connected to a motor, and an electric telescopic rod being sleeved on the screw, the outer end of the electric telescopic rod being rotatably connected to an arc-shaped pressure plate, the test platform being further provided with a positioning component for placing and supporting the deflector, and a laser probe being embedded in the fixing seat.

[0005] The following improvement is made in the solution of the present application: a slide groove is provided on the track along the length direction, a slider is installed in the slide groove, and the top end of the slider is fixedly connected to the bottom end of the fixed seat.

[0006] The present invention provides the following improvements: a second motor is mounted on the electric telescopic rod, and a through slot is defined at the outer end of the electric telescopic rod. The rotating shaft of the second motor extends into the through slot, and a sleeve is mounted on the rotating shaft. One side of the sleeve extends outward from the through slot and is fixedly connected to the arc-shaped pressure plate. By coordinating the arrangement of the second motor and the sleeve, the second motor is started, and the rotating shaft drives the sleeve to rotate within the through slot, thereby driving the arc-shaped pressure plate to rotate, thereby adjusting the contact angle between the arc-shaped pressure plate and the guide plate, ensuring a close fit between the arc-shaped pressure plate and the guide plate.

[0007] The following improvements are made in the present application: the guide plate includes a main body and a connecting ear, the positioning assembly includes a supporting back plate and a base, the inner end face of the supporting back plate is fitted with the outer end face of the main body, and a positioning hole is provided on the base to match the connecting ear.

[0008] The following improvement is made in the solution of the present application: side panels are provided at both ends of the support back panel along the length direction, and the inner end surfaces of the side panels are in contact with the side edges of the main body.

[0009] Compared with the prior art, the present invention provides a vehicle air deflector assembly inspection fixture, which has the following beneficial effects:

[0010] The utility model can play a role of fine-tuning the shaping of the guide plate in a hot and soft state while performing surface detection on the guide plate after injection molding through the coordinated arrangement between the fixing seat, the arc-shaped pressure plate and the positioning assembly, so as to prevent the guide plate from being deformed under the action of thermal expansion and contraction, thereby affecting the production quality. By sliding the position of the fixing seat on the track and then starting the motor to drive the screw to rotate, the electric telescopic rod and the arc-shaped pressure plate can be moved to the appropriate position, and the front end of the arc-shaped pressure plate is pressed against the guide plate to cooperate with the supporting back plate to shape it. At the same time, the thickness of the guide plate is detected by the laser ranging probe to ensure that the surface quality meets the standards. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] like Figure 1-4 As shown, a vehicle air deflector assembly inspection fixture includes a test platform 1 for fixing the deflector 2, wherein the test platform 1 is provided with a track 11, and a fixing seat 3 is slidably mounted on the track 11 along the length direction. The number of the fixing seats 3 can be set according to the degree of thermal softness of the deflector 2. The deflector 2 includes a main body 21 and a connecting ear 22.

[0018] A slide groove 12 is provided on the track 11 along the length direction, and a slider 13 is installed in the slide groove 12. The top of the slider 13 is fixedly connected to the bottom end of the fixed seat 2. The fixed seat 2 can move left and right on the track 11 through the slider 13. A mounting groove 31 is provided on the fixed seat 3, and a screw 32 is provided in the mounting groove 31. One end of the screw 32 passes through the top of the fixed seat 3 and is connected to a motor 1 33, and an electric telescopic rod 34 is sleeved on the screw 32. The outer end of the electric telescopic rod 34 is rotatably connected to an arc pressure plate 35. The outer end surface of the arc pressure plate 35 can fit with the guide plate body 21. A motor 2 37 is installed on the electric telescopic rod 34, and a through groove 3 is provided on the outer end of the electric telescopic rod 34. 41. The rotating shaft of motor 2 37 extends into the through slot 341. A sleeve 38 is mounted on the rotating shaft.

One side of the sleeve 38 extends to the outside of the through slot 341 and is fixedly connected to the arc pressure plate 35. When in use, the arc pressure plate 35 is moved and adjusted in the horizontal direction with the cooperation of the slide groove 12 and the slider 13, and is moved and adjusted in the vertical direction with the cooperation of the screw 32 and motor 1 33.
