Description

A handrail assembly inspection tool Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically to a handrail assembly inspection tool. Background Technology

[0002] In the automotive manufacturing industry, the armrest assembly is an important component of the interior, and its assembly precision and appearance quality directly affect the overall comfort and aesthetics of the vehicle. Therefore, rigorous inspection of the armrest assembly's dimensions, angles, and appearance defects is an essential step in the production process.

[0003] Traditional inspection methods mainly rely on manual visual inspection or single-function fixtures, which suffer from insufficient positioning accuracy and limited locking methods. Specifically, traditional fixtures typically use a single reference plane or a simple three-point positioning method, making it difficult to achieve accurate positioning of the product in its entire circumference. For locking methods, most rely on bolt fixing or clamp locking, which is cumbersome and inefficient, failing to meet the needs of mass production. Therefore, a new handrail assembly fixture needs to be designed to solve these problems. Summary of the Invention

[0004] To address the problems in the background art, this utility model proposes a handrail assembly inspection tool. This utility model adopts a locking mechanism and an integrated detection module, which improves the detection accuracy and efficiency.

[0005] To solve the above problems, this utility model adopts the following technical solution: a handrail assembly inspection fixture, including a connecting frame for mounting on a workbench, a rotating mechanism rotatably mounted below the connecting frame, a base plate supported on the connecting frame, positioning seats and support blocks spaced apart on the base plate, the positioning seats and support blocks respectively used to support and position the two ends of the product to be inspected, a reference block and a protective cover provided on the positioning seat, the reference block used to fit against the product to be inspected, the protective cover used to mate with the outer side of the product to be inspected, a composite locking mechanism provided on the base plate at the position corresponding to the positioning seat, the composite locking mechanism used to fix the product to be inspected on the positioning seat, an angle detection module provided on the base plate corresponding to the outer side of the product to be inspected, the angle detection module mating with the side of the product to be inspected.

[0006] Furthermore, the reference block is provided with a reference surface group A, which includes supporting reference surfaces A1, A2, A3 and A4, a top limiting reference surface A5, and a bottom fixing reference surface A6. A1 and A2 are symmetrically arranged with A3 and A4. The reference surface group A constitutes a six-point fully constrained positioning structure. A reference surface B is provided on the longitudinal axis of symmetry of the product to be inspected, and a reference surface C is provided on the transverse support end.

[0007] Furthermore, the composite locking mechanism includes an electric adsorption module and a manual tightening module, both of which are mounted on the positioning seat and locked together with the product to be inspected.

[0008] Furthermore, the electric adsorption module includes an electromagnet and a control circuit. The electromagnet is embedded in the positioning seat, and a ferromagnetic material is provided on the product to be inspected corresponding to the electromagnet. The electromagnet is electrically connected to the control circuit and can be magnetically attracted to the product to be inspected.

[0009] Furthermore, the manual tightening module includes a threaded locking pin and an elastic reset component. The threaded locking pin rotates through the positioning seat and is locked to the product to be inspected. The elastic reset component is disposed on the threaded locking pin and the positioning seat to automatically retract the threaded locking pin after unlocking.

[0010] The beneficial effects of this utility model are as follows: By setting a reference block to cooperate with the product to be inspected, the force positioning accuracy is improved. By setting a composite locking mechanism, the fixing and locking efficiency of the product to be inspected is improved.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This invention improves force positioning accuracy by setting a reference block 6 to cooperate with the product to be inspected, and improves the fixing and locking efficiency of the product to be inspected by setting a composite locking mechanism 8. By driving the product to be inspected to rotate through a rotating mechanism and cooperating with the angle detection module, it is possible to simultaneously detect complete appearance defects and angle detection, further improving the detection efficiency.

[0019] Specifically, as shown in Figures 1 to 4, a handrail assembly inspection fixture includes a connecting frame 2 for mounting on a workbench 1. A rotating mechanism is rotatably mounted below the connecting frame 2. A base plate 3 is supported on the connecting frame 2. Positioning seats 4 and support blocks 5 are spaced apart on the base plate 3. The positioning seats 4 and support blocks 5 are used to support and position the two ends of the product to be inspected, respectively. A reference block 6 and a protective cover 7 are provided on the positioning seat 4. The reference block 6 is used to fit against the product to be inspected, and the protective cover 7 is used to connect with the outer side of the product to be inspected. A composite locking mechanism 8 is provided on the base plate 3 at a position corresponding to the positioning seat 4. The composite locking mechanism 8 is used to fix the product to be inspected on the positioning seat 4. An angle detection module is provided on the base plate 3 corresponding to the outer side of the product to be inspected. The angle detection module is engaged with the side of the product to be inspected.

[0020] Furthermore, the reference block 6 is provided with a reference surface group A, which includes supporting reference surfaces A1, A2, A3 and A4, a top limiting reference surface A5, and a bottom fixing reference surface A6. A1 and A2 are symmetrically arranged with A3 and A4. The reference surface group A constitutes a six-point fully constrained positioning structure. A reference surface B is provided on the longitudinal axis of symmetry of the product to be inspected, and a reference surface C is provided on the transverse support end.

[0021] Furthermore, the composite locking mechanism 8 includes an electric adsorption module 9 and a manual tightening module 10, both of which are mounted on the positioning seat 4 and locked together with the product to be inspected.

[0022] Furthermore, the electric adsorption module 9 includes an electromagnet and a control circuit. The electromagnet is embedded in the positioning seat 4, and a ferromagnetic material is provided on the product to be inspected corresponding to the electromagnet. The electromagnet is electrically connected to the control circuit and can be magnetically attracted to the product to be inspected.

[0023] Furthermore, the manual tightening module 10 includes a threaded locking pin and an elastic reset member. The threaded locking pin rotates through the positioning seat 4 and is locked to the product to be inspected. The elastic reset member is disposed on the threaded locking pin and the positioning seat 4 for automatically retracting the threaded locking pin after unlocking.

[0024] Specifically, the rotating mechanism includes a rotating platform, an angle limiter, a servo motor, and a photoelectric sensor. The rotating platform is mounted on the worktable 1, and the top of the rotating platform is connected to the connecting frame 2. The angle limiter is mounted on the rotating platform. The servo motor is driven and connected to the rotating platform and supports programmed control of the rotation angle and dwell time. The photoelectric sensor is mounted on the edge of the rotating platform to detect the arrival signal of the product to be inspected and feed it back to the control system.

[0025] In use, the product to be inspected is first cleaned and placed on the inspection fixture, conforming to the A1-A6 reference surfaces. Depending on actual production needs, either an electromagnet or a threaded locking pin is used to fix and lock the product. A rotating mechanism drives the product to rotate, allowing operators to observe appearance defects at different angles. The angle detection module is then used to verify whether the product's dimensions conform to the drawing tolerances. This invention improves positioning accuracy through a six-point fully constrained reference surface design. The combination of electric adsorption and manual tightening improves work efficiency. Furthermore, it allows for mode switching during power outages or equipment failures, ensuring production continuity and reducing downtime losses. By using rotation to drive appearance and angle detection, it can meet inspection needs in multiple scenarios.
