Description

Technical Field

[0001] This utility model relates to the field of automotive interior parts testing technology, specifically to a tooling for testing automotive air vents. Background Technology

[0002] During the assembly of automotive air conditioning vents, the dimensional accuracy of the vent body's edge directly affects its matching quality with the dashboard. If the edge contour deviates from tolerances (such as width, height, or curvature deviations), the following problems will occur: Assembly interference: excessively thick edges or protruding parts cannot be fitted into the dashboard's pre-drilled holes; Uneven gaps: irregular edges cause gaps of varying widths between the vent and the dashboard, affecting aesthetics and duct sealing; Risk of abnormal noise: assembly stress concentration can cause vibration and abnormal noise during vehicle operation. Therefore, strict dimensional accuracy testing is necessary. Current testing methods typically use coordinate measuring machines (CMMs) to inspect automotive parts. The high precision and intelligence of this tool have led to its widespread use. However, CMMs are expensive, require highly skilled operators, and are time-consuming to inspect, which does not meet actual production needs. Utility Model Content

[0003] The purpose of this utility model is to provide a tooling for inspecting automotive air vents, in order to solve the technical problems of existing coordinate measuring machines being expensive, requiring high operator skill, and taking a long time to inspect parts, which do not meet the needs of actual production.

[0004] A vehicle air vent testing fixture includes a base frame and a mounting block assembly mounted on the base frame. The mounting block assembly includes a clamping part and a contour positioning block. The clamping part is used to support and position the vehicle air vent body on the base frame. The contour positioning block has a testing area for the vehicle air vent body to be tested to extend into. A testing gap is provided between the testing area and the vehicle air vent body. A go / no-go gauge is provided in the testing gap. The go / no-go gauge has at least one through end and one stop end for testing the vehicle air vent body.

[0005] Preferably, the clamping part includes a clamping arm and a locking head. One end of the clamping arm is hinged to the contour positioning block, and the other end of the clamping arm abuts against the vehicle air vent body. The locking head is loosely and tightly installed on the contour positioning block to adjust the clamping strength on the vehicle air vent body.

[0006] Preferably, there are at least two contour positioning blocks, and both contour positioning blocks are mounted on the base frame in an adjustable manner.

[0007] Preferably, the diameter of the through end of the go / no-go gauge corresponds to the lower limit of the minimum allowable opening tolerance, and the diameter of the no-go end corresponds to the upper limit of the maximum allowable opening tolerance.

[0008] Preferably, both the through end and the stop end of the go / no-go gauge are detachable.

[0009] Preferably, the base frame is provided with a mounting seat, and the go / no-go gauge is placed in the mounting seat.

[0010] The advantages of this utility model are as follows: by positioning the car air vent body on the contour positioning block to simulate the real assembly state, and then positioning the car air vent body by the clamping part to prevent displacement, so as to ensure that the detection gap position between the detection area and the car air vent body is constant, and then the go / no-go gauge is used to determine whether the edge size of the car air vent body is within the tolerance zone. The detection result can directly reflect the assembly qualification rate, which is convenient, fast and meets the actual production needs. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figures 1 to 3 As shown, a vehicle air vent testing fixture includes a base frame 1 and a mounting block assembly mounted on the base frame 1. The mounting block assembly includes a clamping part and a contour positioning block 2. The clamping part is used to support and position the vehicle air vent body 3 on the base frame 1. The contour positioning block 2 is provided with a testing area for the vehicle air vent body 3 to be tested to extend into. A testing gap 4 is provided between the testing area and the vehicle air vent body 3. A go / no-go gauge 5 is provided in the testing gap 4. The go / no-go gauge 5 has at least one through end and one stop end for testing the vehicle air vent body 3.

[0017] In this embodiment, the clamping part includes a clamping arm 6 and a locking head 7. One end of the clamping arm 6 is hinged to the contour positioning block 2, and the other end of the clamping arm 6 abuts against the car air vent body 3. The locking head 7 can be loosely or tightly installed on the contour positioning block 2 to adjust the clamping strength of the car air vent body 3. It can detect various models of car air vent bodies 3 and has strong adaptability.

[0018] In this embodiment, there are at least two contour positioning blocks 2, and both contour positioning blocks 2 are mounted on the base frame 1 in an adjustable manner to further enhance the adaptability of the detection.

[0019] In this embodiment, the diameter of the through end of the go / no-go gauge 5 corresponds to the lower limit of the minimum allowable opening tolerance, and the diameter of the no-go end corresponds to the upper limit of the maximum allowable opening tolerance.

[0020] In this embodiment, both the through end and the stop end of the go / no-go gauge 5 are detachable and can be replaced with go / no-go gauges of appropriate specifications according to the batch of car air vent bodies 3 to be inspected.

[0021] In this embodiment, the base frame 1 is provided with a mounting base 8, and the go / no-go gauge 5 is placed inside the mounting base 8 to avoid confusion or loss.

[0022] Working process and principle: In this embodiment, the car air vent body 3 to be tested is first inserted into the detection area on the contour positioning block 2. The curved contour of the contour positioning block 2 matches the edge of the car air vent body 3, so that the edge of the car air vent body 3 can be completely embedded in the detection gap 4 to simulate the real assembly state. Then, the car air vent body 3 is positioned by the clamping part to prevent displacement, so as to ensure that the position of the detection gap 4 between the detection area and the car air vent body 3 is constant. Then, the go / no-go gauge 5 is used to determine whether the edge size of the car air vent body 3 is within the tolerance zone. The detection result can directly reflect the assembly qualification rate. If the through end of the go / no-go gauge 5 can be inserted into the detection gap 4 but the stop end cannot be inserted into the detection gap 4, then the quality of the car air vent body 3 is deemed to be qualified. However, if the through end of the go / no-go gauge 5 cannot be inserted, there may be a risk of assembly interference. If the stop end of the go / no-go gauge 5 can be inserted, there may be a risk of air leakage.

[0023] Based on the above, this utility model simulates the actual assembly state by positioning the car air vent body 3 on the contour positioning block 2, and then positioning the car air vent body 3 by the clamping part to prevent displacement, so as to ensure that the position of the detection gap 4 between the detection area and the car air vent body 3 is constant. Then, the go / no-go gauge 5 is used to determine whether the edge size of the car air vent body 3 is within the tolerance zone. The detection result can directly reflect the assembly qualification rate, which is convenient, fast and meets the actual production needs.

[0024] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
