Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing detection equipment, in particular to a rear floor assembly detection carrier. Background Art

[0002] After manufacturing, new energy vehicle parts require various inspection methods for quality control. The rear floor is a crucial component of the vehicle. Workers typically mount the rear floor on a measuring fixture before performing various dimensional inspections. However, the rear floor's large size makes it difficult to locate and measure. Chinese utility model patent application number CN217058572U discloses a vehicle rear floor positioning and measurement jig. The jig features multiple inspection holes on both ends and in the middle of a simulated block. After the rear floor is clamped to the jig, inspection pins can be used to inspect each hole. Multiple clamps are located at both ends of the jig, securing the ends of the rear floor to the pads of the simulated block. Multiple clamps are also located on both sides of the jig, with their pressure heads extending into the middle of the rear floor, pressing it against the pads of the simulated block. This eliminates the problem of insufficient rear floor adhesion, provides a good clamping effect, and improves trimming accuracy. Surface detectors are also installed on both ends and sides of the jig. Each pressure plate of the surface detector accurately corresponds to the position of each surface of the rear floor, providing extensive coverage of the rear floor surface and improving surface accuracy at all locations. However, this solution does not inspect the surface contour of the rear floor. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a detection fixture fixing structure which is convenient for detecting the surface contours of rear floors of different models of cars.

[0004] The present invention solves the technical problem by adopting the following technical solution: a rear floor assembly inspection carrier, comprising a front stand, a rear stand, a crossbeam, and a plurality of rear floor inspection blocks. The two ends of the crossbeam are respectively connected to the front stand and the rear stand. The left and right sides of the crossbeam are respectively provided with a groove body arranged from front to back. A plurality of adjustment bolts are installed in the groove body so as to slide back and forth. Each rear floor inspection block comprises a connecting plate and a profile inspection block. One end of the connecting plate is provided with a mounting hole for the adjustment bolt. The other end of the connecting plate is connected to the profile inspection block. The profile inspection block is provided with a detection portion that matches the surface contour of a standard automobile rear floor. When in use, the corresponding rear floor inspection block is installed at the corresponding position of the crossbeam according to the design standard. The crossbeam is then fixed above the rear floor of the automobile to be inspected through the front stand and the rear stand. By comparing the matching degree between the profile inspection block and the rear floor of the automobile to be inspected, it is determined whether the rear floor of the automobile to be inspected is qualified.

[0005] Furthermore, the connecting plate is in an "L" shape, which is convenient for installation.

[0006] Furthermore, two handles are installed on the upper end surface of the beam to facilitate holding and testing.

[0007] Furthermore, the cross section of the trough body is in an inverted "T" shape, so that the screw end of the adjusting bolt can extend out of the trough body, which is convenient for installation.

[0008] Furthermore, the crossbeam is made of aluminum alloy profiles, which is light and easy to produce.

[0009] The beneficial effects of the utility model are: the measuring tool has a simple structure, is easy to use, and improves measurement efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 and Figure 2 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION

[0011] The following is a further description of the present invention in conjunction with the accompanying drawings. Figure 1 As a reference standard.

[0012] A rear floor assembly detection carrier, such as Figure 1 and Figure 2 As shown, the system comprises a front stand 1, a rear stand 2, a crossbeam 3, and several rear floor inspection blocks. The two ends of the crossbeam 3 connect the front stand 1 and the rear stand 2, respectively. The left and right sides of the crossbeam 3 are provided with front-to-back slots, each containing several adjustment bolts that can slide back and forth. Each rear floor inspection block comprises a connecting plate 41 and a profile inspection block 42. One end of the connecting plate 41 has mounting holes for the adjustment bolts, and the other end of the connecting plate 41 connects to the profile inspection block. Each profile inspection block has a detection portion that matches the surface contour of a standard automobile rear floor. During use, the corresponding rear floor inspection block is installed on the corresponding position of the crossbeam 3 according to the design standard. The crossbeam 3 is then secured above the rear floor of the vehicle to be inspected via the front stand 1 and the rear stand 2. The conformity of the profile inspection block with the rear floor of the vehicle to be inspected is then determined by comparing the conformity of the profile inspection block with the rear floor of the vehicle to be inspected.

[0013] Furthermore, the connecting plate 41 is L-shaped, and the mounting holes are provided on the vertical surface of the connecting plate 41 to facilitate installation. In addition, the vertical surface of the connecting plate 41 is also provided with a plurality of locking holes, which can be fastened with screws to fix the rear floor detection block to the crossbeam 2.

[0014] Furthermore, the connecting plate 41 may be provided with a plurality of positioning pins so as to detect the holes on the rear floor of the vehicle to be inspected.

[0015] Furthermore, two handles are installed on the upper end surface of the beam 3 to facilitate holding and testing.

[0016] Furthermore, the cross section of the trough body is in an inverted "T" shape, so that the screw end of the adjusting bolt can extend out of the trough body, which is convenient for installation.

[0017] Furthermore, the crossbeam 3 is made of aluminum alloy profiles, which is light and easy to produce.

[0018] The above description is only a preferred embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. In other words, any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the utility model description are still within the scope of the present utility model patent.
