After the production of the main and auxiliary instrument panel assemblies is completed, they will be placed in the main and auxiliary instrument assembly inspection fixture for inspection. However, since the existing main and auxiliary instrument assembly inspection fixtures are still installed manually, it takes a lot of time to install the main and auxiliary instrument assemblies during inspection. In addition, due to the influence of human factors during installation, the workers will push the deformed materials to a position that fits the inspection fixture by hand pressure during the process of tightening the screws, resulting in the situation that the product is correctly inspected during installation. However, when this product is delivered to the vehicle for installation, due to the small internal space, a slight warping of the edge will make it difficult to install.

Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 8 As shown, the main and auxiliary instrument assembly inspection fixture and its use method include:

[0035] The fuselage, placed on the ground, serves as the main body of the device;

[0036] A mounting frame 1, fixed to the fuselage, the mounting frame 1 is used to install the instrument panel assembly;

[0037] The locking device has one end fixed on the mounting frame 1 and the other end that can slide out along the mounting frame 1. The locking device is used to pull the instrument panel assembly toward the mounting frame 1 in the same direction. The locking device includes a locking head 61 that slides out of the mounting frame 1, a clamping seat 32 that clamps the locker 33 to move, and a cylinder 31 that pushes the clamping seat 32 to move.

[0038] The fitting device is fixed on the mounting frame 1 in the middle, and can slide out along the mounting frame 1 on both sides. The fitting device is used to pull the instrument panel assembly closer to the mounting frame 1; the fitting device includes two "L"-shaped power frames 22 that slide in contact with each other, a rotating motor 21 located between the two power frames 22 and meshing with the power frames 22 for transmission, and a lock 23 clamped at one end of the power frame 22 away from each other.

[0039] Both locker 1 23 and locker 2 33 use a locking head 61, and the locking head 61 is rotatably provided with an abutment device for abutting the instrument panel assembly, and the abutment device includes an abutment joint 62, a push rod 63 and a power rod 64, one end of the abutment joint 62 is rotatably connected to the locking head 61, and the other end is a free end, the power rod 64 rotates in the locking head 61, one end of the push rod 63 is rotatably connected to the free end of the abutment joint 62, and the other end slides through the locking head 61 and is rotatably connected to the abutment joint 62.

[0040] The detection device 4 is slidably mounted on the mounting frame 1. The detection device 4 is in a "U" shape and three sides thereof can slide relatively.

[0041] Since the fixing points on the main and auxiliary instrument panel assemblies are of two types: one-sided vehicle-fitting type and two-sided inward-wrapping vehicle type, this product takes into account the need to completely eliminate human involvement and simulate the actual installation situation of the product. Therefore, the product is fixed by a fitting device and a locking device to simulate the actual installation situation.

[0042] When using this product, first place the main and auxiliary instrument panel assemblies on the corresponding parts of the mounting frame 1. Since the shape of the mounting frame 1 imitates the shape of the corresponding position of the vehicle interior, after the main and auxiliary instrument panel assemblies are placed, they will be attached to the mounting frame 1 due to the influence of gravity. At this time, the main and auxiliary instrument panel assemblies have not been fixed, so they cannot be tested. Traditional inspection tools require workers to intervene at this time to fix the main and auxiliary instrument panel assemblies with bolts. However, due to the subjective consciousness of workers, when encountering a slightly deformed main and auxiliary instrument panel assembly, they often rely on manual pressure to push the main and auxiliary instrument panel assemblies. Then, the bolts are tightened again, resulting in the main and auxiliary instrument panel assemblies with small deformations that cannot be detected. To avoid this situation, this product stops manual intervention after the workers place the main and auxiliary instrument panel assemblies in the corresponding positions. At this time, it is only necessary to start the device, and the cylinder 31 on the device will push the clamping seat 32, so that the clamping seat 32 drives the lock 2 33 to pass through the surface of the main and auxiliary instrument panel assemblies, and then start the abutment device, and the power rod 64 inside the abutment device rotates, prompting the push rod 63 to move, and the push rod 63 moves outward to push the abutment joint 62 to release The abutment head 62 rotates to protrude from the surface of the locking head 61, so that the axial distance between the abutment head 62 and the locking head 61 is greater than the aperture of the fixing hole of the main and auxiliary instrument panel assemblies. At this time, the cylinder 31 can retract. During the retraction, the abutment head 62 abuts against the main and auxiliary instrument panel assemblies, so that the main and auxiliary instrument panel assemblies are fixed. If the deformed main and auxiliary instrument panel assemblies do not meet the standards when the locking head 61 is extended, they will not be abutted by the abutment head 62. At this time, it can be known that this product does not meet the standards, and the materials that meet the standards are fixed. After that, the edge of the material can be detected by the detection device 4, and the detection data can be generated at the same time. If the edge thickness and the fit gap size meet the product requirements, it is judged as a qualified product, otherwise it is a defective product. After the detection is completed, the cylinder 31 pushes the clamping seat 32 to move again. After the abutment joint 62 is separated from the main and auxiliary instrument panel assembly, the abutment device is started again to make the abutment joint 62 shrink into the locking head 61, and then the clamping seat 32 is pulled by the cylinder 31 to make the locking head 61 shrink into the main and auxiliary instrument panel assembly. At this time, unloading can be carried out.

[0043] An action rod 65 is slidably sleeved in the push rod 63, and an inverted hourglass-shaped guide groove 651 is provided on the action rod 65. A guide pin 641 is passed through the push rod 63, and a sliding shuttle 67 that slides in the guide groove 651 is rotatably provided on the guide pin 641. The action rod 65 is moved axially along the locking head 61, so that the guide groove 651 on the action rod 65 pushes the push rod 63, thereby causing the push rod 63 to rotate. By utilizing the characteristic that the locking head 61 itself needs to move in the axial direction, the kinetic energy of the axial movement is converted into a rotation direction, thereby causing the action rod 65 to rotate, so as to achieve the effect of allowing the action rod 65 to push the push rod 63 to extend the abutment head 62.

[0044] The locking head 61 is provided with a guide head 66 for removal. The guide head 66 can make it easier for the locking head 61 to pass through the main and auxiliary instrument panel assemblies and can also play a slight correction effect. A spring is provided between the actuating rod 65 and the locking head 61. A pull rope 5 for pulling the actuating rod 65 to overcome the elasticity of the spring is provided between the mounting frame 1 and the actuating rod 65. The pull rope 5 has the characteristics of high strength in tension and no force in thrust, so that when the pull rope 5 is stretched straight, the locking head 61 continues to move, which will prompt the pull rope 5 to pull the actuating rod 65, thereby causing the actuating rod 65 to slide. After the actuating rod 65 slides, it is restricted along the circumferential direction of the locking head 61, so that the actuating rod 65 can only move axially. Since the actuating rod 65 has a guide groove 651 and the sliding shuttle 67 slides in the guide groove 651, when the actuating rod 65 moves, the sliding shuttle 67 is located in the guide groove 651. The movable shuttle 67 will be subjected to the axial force to slide along the guide groove 651, causing the power rod 64 to rotate, so that the power rod 64 pushes the push rod 63, causing the abutment 62 to extend out of the locking head 61. When the abutment 62 extends out of the locking head 61, since the locking head 61 needs to pull the main and auxiliary instrument panel assemblies to fit the mold, the locking head 61 retracts at this time, and the pull rope 5 changes from a stretched state to a loose state. The spring loses the tension of the pull rope 5 and begins to reset. When the spring resets, it pushes the action rod 65 to move. Since the guide groove 651 is hourglass-shaped and a drop is formed at the junction of each area, the sliding direction of the sliding shuttle 67 in the guide groove 651 is always kept in a fixed direction. The length of the sliding shuttle 67 is greater than the width of the guide groove 651, so that the sliding shuttle 67 will not slide to other directions when passing the intersection of the guide groove 651.

[0045] like Figure 6 , Figure 7As shown, the guide groove 651 of the product is divided into a steering groove and a sliding groove, a magnet 1 71 is arranged at the connection between the steering groove and the sliding groove, a magnet 2 72 is arranged inside the steering groove, and a magnet 3 73 is arranged at the tail end of the sliding shuttle 67 along the sliding direction, the magnet 3 73 and the magnet 1 71 repel each other, and the magnet 3 73 and the magnet 2 72 attract each other, through the cooperation of the magnet 1 71, the magnet 2 72 and the magnet 3 73, the sliding shuttle 67 can turn quickly when entering the steering groove, thereby avoiding the situation of getting stuck during the next sliding, and the sliding shuttle 67 is set to be large at both ends and small in the middle and has a streamlined design.

[0046] A push-pull force sensor is arranged between the second lock 33 and the clamping seat 32, and a push-pull force sensor is also arranged between the first lock 23 and the power frame 22. The push-pull force sensor is used to monitor the force generated when the abutment joint 62 and the main and auxiliary instrument assemblies are in contact, so as to detect the degree of deformation of the main and auxiliary instrument assemblies. Since the main and auxiliary instrument assemblies themselves are elastic, when they receive the pulling force toward the mounting frame 1, they will instinctively generate resistance. At this time, the magnitude of the resistance is known through the pulling force. When the resistance is higher than the threshold, it is obtained that the product thickness is too thick and does not meet the standard requirements or the deformation is excessive. When the resistance is less than the threshold, it is obtained that the product thickness is too thin. Both are marked as defective products and require secondary inspection. When the pulling force data does not fluctuate, it is determined that the installation aperture of the main and auxiliary instrument assemblies is too large or the product deformation seriously exceeds the standard, resulting in the inability of the abutment joint 62 to normally abut the main and auxiliary instrument assemblies. At this time, the product is marked as unqualified.

[0047] like Figure 8 As shown, the detection device 4 includes a detection seat 41, two clamping probes 42 sliding on both sides of the detection seat 41 and a detection head 43 sliding in the middle of the detection seat 41. Displacement sensors independently connected to the detection head 43 and the clamping probe 42 are arranged in the detection seat 41. The detection device 4 is arranged in a U-shape, so that when the detection seat 41 moves to the point where the detection head 43 contacts the main and auxiliary instrument assemblies, the detection head 43 detects the distance between the main and auxiliary instrument assemblies and the mounting frame 1, thereby obtaining the gap that will be generated after the main and auxiliary instrument assemblies are installed on the vehicle. After the detection head 43 contacts the main and auxiliary instrument assemblies, the clamping probes 42 located on both sides of the detection seat 41 approach each other. When the clamping probe 42 contacts the main and auxiliary instrument assemblies, the thickness of the main and auxiliary instrument assemblies can be detected. Then the detection device 4 moves around along the bottom of the mounting frame 1. At this time, the thickness of the overall edge of the main and auxiliary instrument assemblies can be detected, as well as whether there is deformation, and whether wavy edges will appear after the installation is completed.

[0049] S1 loading, placing the components of the instrument panel assembly on the mounting frame 1 according to their positions;

[0050] S2 positioning, start positioning, the control center starts the rotation motor 21 and the cylinder 31 to extend, so that the locking head 61 extends out of the assembly surface;

[0051] S3 Fixing, starting fixing, the control center starts the rotating motor 21 and the cylinder 31 to retract, so that the locking head 61 abuts against the assembly surface;

[0052] S4 detection, start detection, the control center starts the detection device 4, the detection device 4 detects the edge of the assembly and generates a result;

[0053] S5 unloading, the control center starts the rotating motor 21 and the cylinder 31 extends and then retracts immediately, so that the locking head 61 is retracted into the interior of the assembly, and the assembly can be manually removed at this time.
