Detailed Implementation

[0019] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Figure 1 This paper shows a schematic diagram of the structure of an automotive grille form and position tolerance detection device 10 according to this application, combined with... Figure 1 The detection device 10 includes a detection platform 100, a support frame 200, and a movable wall 300. The support frame 200 is connected to the top surface of the detection platform 100. The support frame 200 includes multiple support walls 210, which enclose a positioning space. At least one support wall 210 has a notch 220. The movable wall 300 and the notch 220 are arranged in a one-to-one correspondence. The movable wall 300 can reciprocate along the opening direction of the corresponding notch 220. The movable wall 300 can move inside or outside the corresponding notch 220, or fill the corresponding notch 220. 20, that is, the movable wall 300 has at least three positions: a first position located inside the notch 220, a second position located outside the notch 220, and a third position filling the notch 220. This allows the position of the movable wall 300 to be adjusted according to the shape of the car grille. Through the support of multiple support walls 210 of the support frame 200 and the adjustable movable wall 300, it can support car grilles of different specifications to a certain extent, especially suitable for supporting finely adjusted or modified car grilles, thus reducing the waste of cost resources. Once the movable wall 300 is adjusted to its position, it can be locked, thereby fixing the movable wall 300 relative to the inspection platform 100 for dimensional and positional tolerance inspection of the car grille of that specification. The specific details of the inspection device 10 are now further described with reference to the accompanying drawings.

[0021] The testing device 10 provided in this application can be placed on a support platform so that the testing device 10 has a certain height, which facilitates the quality inspectors to test the car grille placed on the testing device 10.

[0022] In some embodiments, each support wall 210 of the support frame 200 can be bolted to the top surface of the detection platform 100. Part of the support frame 200 can be hollowed out to reduce manufacturing costs and weight, facilitating the turnover of the detection device 10. Furthermore, the positioning space enclosed by the multiple support walls 210 can be square, circular, elliptical, etc., depending on the shape of the car grille; this application does not impose any limitations on this.

[0023] Combination Figure 1 In some embodiments, a single notch 220 is provided and is located in the middle of one side of the support frame 200 in the width direction. In other embodiments, two or more notches 220 may be provided, or the notch 220 may be provided in other positions of the support frame 200. This application does not limit this.

[0024] Combination Figure 1 In some embodiments, the detection device 10 further includes a plurality of support blocks 700, which are bolted to the top surface of the detection platform 100 to support the bottom of the car grille. The heights of the plurality of support blocks 700 may be inconsistent or consistent, depending on the shape of the car grille, which will not be elaborated in this application.

[0025] Combination Figure 1 In some embodiments, in order to enable the reciprocating movement of the movable wall 300, the detection device 10 provided in this application further includes a drive component 400 for driving the reciprocating movement of the movable wall 300. Figure 2 A schematic diagram of the assembly of the drive assembly 400 and the movable wall 300 is shown. Figure 3 It shows Figure 2 An exploded view of the drive component 400. (Combined with...) Figure 2 The drive assembly 400 includes a first fixing block 410 and a drive rod 420. The first fixing block 410 is connected to the top surface of the detection platform 100 and is disposed outside the support frame 200. The first fixing block 410 has a first through hole extending along the moving direction of the moving wall 300. One end of the drive rod 420 is connected to the moving wall 300, and the other end slides through the first through hole. When the moving wall 300 is driven to reciprocate, the movement of the drive rod 420 within the first through hole is controlled, thereby moving the moving wall 300 to adjust its position. For example, the first fixing block 410 can be bolted to the top surface of the detection platform 100, and one end of the drive rod 420 is provided with a connecting block, which can be bolted to the outer side of the corresponding moving wall 300.

[0026] Combination Figure 2After the movable wall 300 is adjusted to its position, it needs to be locked. Therefore, this application provides a second through hole vertically on the top surface of the first fixing block 410, which communicates with the first through hole. The drive assembly 400 also includes a locking rod 430, which is threadedly connected to the first through hole. When the movable wall 300 is fixed, the locking rod 430 is screwed into the second through hole, abutting against the circumferential surface of the drive rod 420. The drive rod 420 is locked by the self-locking of the threads of the locking rod 430 and the second through hole. When the position of the movable wall 300 needs to be adjusted, the locking rod 430 is at least partially unscrewed from the second through hole to lock the drive rod 420, thereby controlling the movement of the drive rod 420 within the first through hole.

[0027] To improve the locking effect on the drive rod 420, the drive assembly 400 of this application also includes a first disc 440 and a second disc 450. Figure 3 It shows Figure 2 The exploded diagrams of the first disk 440 and the second disk 450 are shown in the figure. Figure 2 as well as Figure 3 The first disc 440 is sleeved on the locking rod 430 and located on the first fixing block 410; the second disc 450 is also sleeved on the locking rod 430 and is located on the first disc 440; wherein: the opposing surfaces of the first disc 440 and the second disc 450 are provided with a plurality of wedge-shaped grooves 460, and the plurality of wedge-shaped grooves 460 are spaced apart around the central axis of the locking rod 430. During the process of controlling the locking rod 430 to be screwed into the second through hole, the nut at the end of the locking rod 430 pushes the second disc 450 to move towards the top of the first fixing block 410 until the second disc 450 abuts against the first disc 440. As the locking rod 430 continues to rotate, the wedge grooves 460 of the second disc 450 and the first disc 440 engage and lock. The first disc 440 drives the second disc 450 to move to the top surface of the first fixing block 410. The expansion of the first disc 440 and the second disc 450 along their thickness direction leads to an increase in clamping force.

[0028] Combination Figure 3 In addition, the mating surfaces of the first disc 440 and the second disc 450 are provided with a plurality of friction grooves 470, which are spaced apart around the central axis of the locking rod 430. This arrangement can improve the friction between the second disc 450 and the nut at the end of the locking rod 430, as well as the friction between the first disc 440 and the first fixing block 410.

[0029] It should be noted that the wedge groove 460 and the friction groove shown in this application are arranged radially with respect to the central axis of the corresponding disc.

[0030] Combination Figure 2In some embodiments, each movable wall 300 is configured with two drive components 400, that is, the reciprocating movement of the movable wall 300 is achieved by the synchronous operation of the two drive components 400. In other embodiments, one or more drive components 400 may be configured, depending on the size of the movable wall 300, and this application does not impose any restrictions on this.

[0031] Combination Figure 1 In some embodiments, the detection device 10 further includes a first clamping component 500, which may be disposed between two drive components 400. The first clamping component 500 is connected to the top surface of the detection platform 100. The first clamping component 500 and the moving wall 300 are correspondingly disposed to restrict the positioning of the grid portion placed on the corresponding moving wall 300 by the first clamping component 500. Figure 4 A schematic diagram of the assembly of the first clamping assembly 500 and the movable wall 300 is shown. Figure 4 The first clamping assembly 500 includes a second fixing block 510, a first operating lever 520, a first connecting rod 530, a second connecting rod 540, and a first pressing rod 550. The second fixing block 510 is connected to the top surface of the detection platform 100 and is located outside the notch 220. The first operating lever 520, the first connecting rod 530, and the second connecting rod 540 each have a first end and a second end. The first end of the first operating lever 520 is rotatably connected to the second fixing block 510, and the second end of the first operating lever 520 is directed towards the second fixing block 550. Extending upwards from 10, a first operating space 521 is provided in the middle of the first operating lever 520; the first end of the first connecting rod 530 is rotatably connected to the top of the second fixing block 510, and the second end of the first connecting rod 530 passes through the first operating space 521; the first end of the second connecting rod 540 is rotatably connected to the middle of the first connecting rod 530, and the second end of the second connecting rod 540 is rotatably connected to the first operating lever 520; the first pressing rod 550 is connected to the second end of the first connecting rod 530 to press against the car grille placed on the support frame 200. When it is necessary to place the car grille onto the support frame 200 and the movable wall 300, the first operating lever 520 is controlled to rotate outward. The first operating lever 520 drives the first connecting rod 530 to flip outward through the second connecting rod 540, thereby lifting the first pressing rod 550 and providing space for the placement of the car grille. When the car grille is placed onto the support frame 200 and the movable wall 300, the first operating lever 520 is controlled to rotate inward. The first operating lever 520 drives the first connecting rod 530 to flip inward through the second connecting rod 540, thereby lowering the first pressing rod 550 and pressing the car grille onto the movable wall 300, thereby positioning the car grille on the movable wall 300.

[0032] Combination Figure 4In some embodiments, the first end of the first operating lever 520 is provided with a first U-shaped groove 522 with its opening facing downwards, and a portion of the top of the first fixing block 410 is disposed within the first U-shaped groove 522; the first pressing assembly 500 also includes a first rotating shaft 560 and a second rotating shaft 570, the two ends of the first rotating shaft 560 are respectively connected to the two side walls of the first U-shaped groove 522, and the first rotating shaft 560 rotates through the top of the first fixing block 410 to realize the rotational connection between the first operating lever 520 and the first fixing block 410; the second rotating shaft 570 is located above the first rotating shaft 560, the two ends of the second rotating shaft 570 are respectively connected to the two side walls of the first U-shaped groove 522, and the rotation of the second rotating shaft 570 passes through the second end of the second connecting rod 540 to realize the rotational connection between the second connecting rod 540 and the first operating lever 520.

[0033] Figure 5 It shows Figure 4 A schematic diagram of the structure of the first clamping component 500. (Combined with...) Figure 4 as well as Figure 5 In some embodiments, two second connecting rods 540 are arranged side by side; the first pressing assembly 500 also includes a pressing member 580, which is U-shaped and has two ends connected to the two second connecting rods 540 respectively. The middle part of the pressing member 580 can press against the top of the first connecting rod 530. When the first operating lever 520 is rotated inward, the first operating lever 520 drives the pressing member 580 to press against the top of the first connecting rod 530 and drives the first connecting rod 530 to flip inward, thereby lowering the first pressing rod 550 so that the first pressing rod 550 presses against the car grille on the movable wall 300, thereby positioning the car grille on the movable wall 300.

[0034] Combination Figure 4 as well as Figure 5 In addition, the first pressing rod 550 and the first connecting rod 530 are perpendicular to each other. The pressing end of the first pressing rod 550 may be covered with a first elastic layer 590, which may be rubber or velvet, so that the first pressing rod 550 can make elastic contact with the car grille and reduce the risk of damage to the appearance of the car grille.

[0035] Combination Figure 1 In some embodiments, the detection device 10 further includes a plurality of second clamping components 600, which are connected to the top surface of the detection platform 100 and are arranged around the periphery of the support frame 200. Figure 6 A schematic diagram of the structure of the second clamping assembly 600 is shown, in conjunction with... Figure 6Each second clamping assembly 600 has a rotatable second clamping rod 660 to clamp the car grille placed on the support frame 200. By setting up multiple second clamping assemblies 600, the periphery of the car grille placed on the support frame 200 can be positioned, so that the car grille is stably positioned on the support frame 200.

[0036] Combination Figure 6In some embodiments, the second clamping assembly 600 includes a third fixing block 610, a second operating rod 620, and a third connecting rod 630. The third fixing block 610 is connected to the top surface of the detection platform 100 and is located outside the support frame 200. The second operating rod 620 and the third connecting rod 630 each have a first end and a second end. The first end of the second operating rod 620 is provided with a second U-shaped groove 621 with its opening facing downwards. The top of the third fixing block 610 is disposed in the second U-shaped groove 621, and the top of the third fixing block 610 is rotatably connected to the two side walls of the second U-shaped groove 621 via a third rotating shaft 670. The first end of the third connecting rod 630 is provided with two opposing connecting walls 640. The top is located between two connecting walls 640, which are rotatably connected to the top of the third fixing block 610 via a fourth rotating shaft 680. The fourth rotating shaft 680 is located outside the third rotating shaft 670. The second pressing rod 660 is connected to the second end of the third connecting rod 630. The two connecting walls 640 are located in the second U-shaped groove 621. A transition portion 650 is provided between each connecting wall 640 and the first end of the third connecting rod 630. The distance between the ends of the two transition portions 650 facing the connecting wall 640 is L1, the distance between the ends of the two transition portions 650 facing the third connecting rod 630 is L2, and the distance between the two side walls of the second U-shaped groove 621 is L3, where L1 < L3 < L2. When the car grille needs to be placed on the support frame 200 and the movable wall 300, the second operating lever 620 is controlled to rotate outward. The two side walls of the second U-shaped groove 621 of the second operating lever 620 press against the connecting wall 640 of the third link 630, thereby driving the third link 630 to flip outward to lift the second pressing rod 660, thus providing space for the placement of the car grille. When the car grille is placed on the support frame 200 and the movable wall 300, the second operating lever 620 is controlled to rotate inward. The two side walls of the second U-shaped groove 621 of the second operating lever 620 press against the transition portion 650 of the third link 630, thereby driving the third link 630 to flip outward to lower the second pressing rod 660, so that the second pressing rod 660 presses against the car grille on the movable wall 300, thereby positioning the car grille on the movable wall 300. Meanwhile, since L1 < L3 < L2, the two side walls of the second U-shaped groove 621 of the second operating lever 620 can be clamped on the transition part 650 of the third connecting rod 630, so that the second operating lever 620 and the third connecting rod 630 are locked together, so that the second pressing rod 660 is kept in the locked position, ensuring that the car grille is stably positioned on the support frame 200.

[0037] In some embodiments, the inner sides of the two sidewalls of the second U-shaped groove 621 of the second operating lever 620 are V-shaped, and the two transition portions 650 are also V-shaped. The second pressing rod 660 is also perpendicular to the third connecting rod 630. The pressing end of the second pressing rod 660 may be covered with a second elastic layer 690, which may be rubber or velvet, so that the second pressing rod 660 makes elastic contact with the car grille, reducing the risk of damage to the appearance of the car grille.

[0038] In summary, the automotive grille form and position tolerance detection device 10 provided in this application, through the support of multiple support walls 210 of the support frame 200 and the adjustable movable wall 300, can support automotive grilles of different specifications to a certain extent. It is particularly suitable for supporting automotive grilles that have undergone minor adjustments and modifications, thereby reducing the waste of cost resources to a certain extent. Through the cooperation of the first clamping component 500 and the second clamping component 600, the automotive grille can be stably positioned on the detection platform 100, so as to facilitate the smooth inspection of automotive grilles by quality inspectors.
