Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and in particular to a rapid matching device for a door inspection tool module. Background Technology

[0002] Automobile manufacturing is a systems integration project. With increasingly faster development cycles, minimizing the impact of design and manufacturing at each stage is crucial to shortening the matching cycle. Ensuring the matching accuracy and efficiency of each component is a key focus for automotive structural designers and process engineers. In the CUBING fixture, the traditional four-door assembly matching module uses four small platforms on a base. During use, the doors are fixed to these platforms, and the platforms and door assemblies are pushed along guide rails on the base before being assembled with a standard body module to check the matching status. However, the small platforms extend approximately 400mm beyond the body module and approximately 800mm in both directions, occupying about 5 square meters of space. 2 Furthermore, the matching status of all four doors when open cannot be visually verified during the assembly and verification of the front and rear door trim panels, which can sometimes affect the matching accuracy. Therefore, there is a need to invent a rapid matching device for the door inspection fixture module that can improve matching efficiency, save space, and avoid insufficient operating space for door trim panel matching.

Detailed Implementation

[0038] like Figures 1 to 5 The illustrated device is a rapid matching device for a door inspection module, the device comprising:

[0039] A rectangular matching platform 1 is used to install a standard vehicle body 100 (CUBING).

[0040] Guide module 2 is symmetrically and fixedly connected to the left and right sides of the matching platform 1, such as... Figures 6 to 8 As shown, the guiding module includes a guide block 21, a guide slope 22 is provided on the guide block 21, and a guide hole 23 is provided on the guide slope 22;

[0041] Door matching component 3 is used for installing the door, such as Figures 12 to 15 As shown, the door matching component 3 includes a base 31 with casters, a support frame 32 is fixedly connected to the base 31, and a lifting frame 33 is connected to the support frame 32 through a slide rail slider assembly. The lifting frame 33 is used to install the door.

[0042] Positioning module 4 is fixedly connected to base 31, such as Figure 9 and Figure 10 As shown, the positioning module 4 includes a positioning pin seat 41, on which a positioning plane 411 adapted to the guide slope 22 is provided, and a positioning pin 42 adapted to the guide hole 23 is provided on the positioning plane 411; when the positioning module 4 is connected to the guide module 2, as Figure 4 As shown, the lifting frame 33 is arranged at an angle α to the side of the matching platform 1, and this angle α is 45 degrees. Therefore, when the car door is fixed on the lifting frame 33, the connection angle between the car door and the standard car body is also 45 degrees.

[0043] To facilitate simultaneous matching of four sets of doors, the matching platform 1 has a rectangular structure, such as... Figure 6 As shown, four sets of guide modules 2 are provided on both the left and right sides of the matching platform 1; as Figure 1 As shown, the door matching assembly 3 is provided in four sets, each set of door matching assembly 3 is used to support and fix one set of doors; in order to increase the stability of positioning guidance, such as Figure 11 and Figure 12 As shown, each set of door matching components 3 is equipped with two sets of positioning modules 4, and each set of positioning modules 4 corresponds to a set of guide modules 2.

[0044] To ensure that all four sets of doors can be matched with the standard vehicle body at the same angle, the four sets of guide ramps 22 located on the same side of the matching platform 1 are all arranged in parallel, the two sets of positioning planes 411 located on the base 31 are arranged in parallel, and the two sets of positioning pins 42 located on the base 31 are arranged in parallel; Figure 11 As shown, when the positioning pin 42 is inserted into the guide hole 23, the guide slope 22 is parallel to and abuts against the positioning plane 411.

[0045] To ensure the car doors are aligned at a 45-degree angle with the standard body, and to visually verify the alignment when all four doors are open, such as... Figure 5 As shown, the guide ramp 22 is arranged at an angle β to the side of the matching platform 1, where β is 45 degrees. When the positioning pin 42 is inserted into the guide hole 23, the lifting frame 33 is perpendicular to the guide ramp 22.

[0046] To ensure that the positioning module 4 is locked in place after assembly with the guide module 2, preventing the module from loosening and detaching, such as... Figure 9 and Figure 10 As shown, a locking mechanism is fixedly connected to the side wall of the positioning pin seat 41. The locking mechanism includes a T-shaped block 43, which is hinged to one end of a Y-shaped pull rod 44. A rotating shaft 45 passes through the pull rod 44, and the upper and lower ends of the rotating shaft 45 are fixedly connected to the two ends of a U-shaped locking rod 46, respectively. Figure 7 and Figure 8 As shown, a locking hook fixing plate 24 is fixedly connected to the guide block 21, and a locking hook 25 is fixedly connected to the locking hook fixing plate 24. The locking hook 25 is used to hook the U-shaped locking rod 46 for locking. In order to make the locking more stable, the locking hooks 25 on the two adjacent sets of guide blocks 21 face opposite directions, and the two sets of locking mechanisms on the same base 31 face opposite directions.

[0047] To facilitate production and processing, and to facilitate the raising and lowering of the car doors, such as Figure 14 and Figure 15 As shown, the support frame 32 has a U-shaped structure, and the slide rail slider assembly is vertically arranged on the left and right sides of the support frame 32. Its slide rail is vertically fixed to the front side of the support frame 32, and the slider is fixedly connected to the rear side of the lifting frame 33. The left and right sides of the support frame 32 can also be connected to the base 31 via diagonal braces to increase structural stability. To prevent the lifting frame 33 from being accidentally raised too high after reaching its position, causing instability after the car door is installed, a limit block 36 is fixedly connected to the side wall of the support frame 32. A limit post 37 is screwed onto the limit block 36, and the limit post 37 is used to limit and block the lower slider.

[0048] To facilitate production and processing, and to make it easier to secure the left and right sides of the car door with bolts, such as Figure 14 and Figure 15 As shown, the lifting frame 33 has a rectangular structure. Two sets of fixing plates 331 are fixedly connected to both the left and right sides of the lifting frame 33. Quick-release bolts 332 are screwed onto the fixing plates 331 and are used to connect with the mounting holes on the left and right sides of the car door.

[0049] Since the matching platform 1 has different heights for different car models, a handwheel lifting mechanism 5 is provided on the door matching assembly 3 to facilitate manual raising and lowering of the lifting frame 33 and better adjust the matching height of the door. Figure 16 As shown, the handwheel lifting mechanism 5 includes a handwheel 51, and a handwheel shaft 52 is fixedly connected to the lower end of the handwheel 51. A threaded section is provided in the middle of the handwheel shaft 52, and a threaded bushing 55 is fitted on the threaded section of the handwheel shaft 52. The threaded bushing 55 is fixedly connected to the lifting frame 33, and the lower end of the handwheel shaft 52 is rotatably connected to the support frame 32.

[0050] To facilitate the assembly and fixation of the lifting mechanism 5, an upper fixing block 56 is fixedly connected to the threaded bushing 55, and the upper fixing block 56 is fixedly connected to the lifting frame 33; a chuck 54 is provided at the lower end of the handwheel shaft 52, and a spherical surface is provided at the lower end of the chuck 54; an annular groove 53 is provided at the part of the handwheel shaft 52 above the chuck 54; the chuck 54 is engaged and rotatably connected in the inverted T-shaped groove 58 of the lower fixing block 57; a circular hole adapted to the spherical surface of the chuck 54 is provided at the bottom of the groove 58; and the lower fixing block 57 is fixedly connected to the support frame 32.

[0051] To provide a buffering effect, upper mounting blocks 333 are fixedly connected to the left and right sides of the upper part of the lifting frame 33, and lower mounting blocks 334 are fixedly connected to the left and right sides near the middle of the support frame 32. The upper mounting blocks 333 and lower mounting blocks 334 are respectively connected to the upper and lower ends of the gas spring 335.

[0052] When using this device, the following steps can be followed:

[0053] First, fix the door to be matched onto the lifting frame 33 using quick-release bolts 332;

[0054] 2. Push the door matching component 3 with the door installed to the side of the matching platform 1, and connect and fix the positioning module 4 to the guide module 2 to complete the guiding positioning. At this time, the connection angle between the door and the standard body is about 45 degrees.

[0055] 3. Turn the handwheel lifting mechanism 5 to adjust the door to the required height, and connect and assemble the hinges on the door to the standard body;

[0056] 4. After the door assembly is completed, unscrew the quick-release bolt 332 to unlock the connection between the door and the lifting frame 33, and unlock the positioning module 4 and the guide module 2. Push away the door matching component 3, and then only the subsequent testing and matching operation needs to be performed.
