Description

Technical Field

[0001] This invention relates to the field of inspection fixtures, and more specifically to a lifting inspection fixture for the rear floor and front panel assembly. Background Technology

[0002] Automobiles are one of the most important means of transportation. Automobiles have many components. In order to ensure the quality of automobiles and driving safety, the components of the vehicle need to be further tested after assembly. The test is to check whether the relative offset of the holes and grooves of the whole after installation is within the acceptable range.

[0003] For the inspection of sheet metal parts, there is an existing rear floor front section inspection fixture assembly with publication number CN217654411U, which includes a worktable, a positioning contour block, an edge clamping mechanism, and a transverse clamping detection mechanism. The positioning contour block is set on the worktable and is used for supporting and positioning the front section of the rear floor to be tested. The edge clamping mechanism is used to clamp the four sides of the front section of the rear floor to be tested. The transverse clamping detection mechanism includes two vertical beams, a horizontal beam, two pins, four clamping detection frames, and four first detection pins. The two vertical beams are fixed on the worktable and are spaced apart on the left and right. The two ends of the horizontal beam are connected to the upper ends of the two vertical beams respectively through two pins. The four clamping detection frames are fixed on the horizontal beam and are used to clamp the periphery of the four seat holes of the front section of the rear floor to be tested. Each of the four clamping detection frames is provided with four first detection holes, which correspond one-to-one with the positions of the four seat holes of the front section of the rear floor to be tested. The first detection pin is used to pass through the seat holes of the front section of the rear floor to be tested and then insert into the first detection hole.

[0004] The rear floor and front panel assembly is one of the components of a vehicle. Existing inspection tools cannot inspect the bottom surface of the rear floor and front panel assembly. Another inspection tool is needed to inspect the bottom surface of the rear floor and front panel assembly. If a coordinate measuring machine is used for inspection, the inspection time is long and the efficiency is low. Therefore, a lifting inspection tool for the rear floor and front panel assembly is needed. Summary of the Invention

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] refer to Figures 1-4The rear floor front panel assembly lifting inspection fixture shown includes a base 1, on which contour-following blocks 2 are disposed, forming a closed contour. Multiple flip-detection components 3 and multiple quick-clamping clamps 4 are disposed on the base 1 around the contour-following blocks 2. An inwardly extending boss is disposed on the base 1 inside the contour-following blocks 2, and a first positioning detection seat 5 and a second positioning detection seat 6 are disposed on the boss. Guide seats 10 are disposed on both sides of the base 1 below the contour-following blocks 2. Each guide seat 10... A first lifting detection component 7 and a second lifting detection component 8 are provided on both sides. The first lifting detection component 7 includes a support base 701, a connecting base 702, a top rod 703, and an elastic push rod 704. The second lifting detection component 8 includes an instrument socket 801, a swing arm 802, a first hinge base 803, and a detection rod 804. An upper detection pressure plate 9 is detachably connected to the base 1 above the contour contour block 2. Detection holes are opened on the first positioning detection seat 5, the second positioning detection seat 6, the instrument socket 801, the upper detection pressure plate 9, and the guide seat 10.

[0020] The flip detection assembly 3 includes a second hinge 301, a rotating bracket 302, and a detection block 303. The second hinge 301 is fixedly connected to the base 1. One end of the rotating bracket 302 is hinged to the second hinge 301. The rotating bracket 302 can flip around the second hinge 301 to make way for the rear floor front panel assembly. The rotating bracket 302 can be fixed to the second hinge 301 with screws. The detection block 303 is fixedly connected to the other end of the rotating bracket 302. The detection block 303 has a hole.

[0021] The contouring block 2, quick clamp 4, and guide seat 10 are all fixedly connected to the base 1. The contouring block 2 is provided with a clearance groove, which can make way for the protruding sheet metal part on the rear floor front panel assembly.

[0022] The support base 701 is fixedly connected to the base 1. The support base 701 is provided with a groove. The middle section of the push rod 703 is hinged to the connecting seat 702. One end of the push rod 703 is tangent to the end of the movable rod of the elastic push rod 704. The other end of the push rod 703 is located in the groove. The push rod of the elastic push rod 704 is slidably connected to the guide seat 10. The guide seat 10 can guide the sliding of the push rod and prevent the push rod from deviating during the sliding process. The spring of the elastic push rod 704 is located between the push rod and the guide seat 10.

[0023] The instrument socket 801 is fixedly connected to the base 1. The middle section of the swing arm 802 is hinged to the instrument socket 801. Both the instrument socket 801 and the guide seat 10 are provided with strip grooves. The detection hole on the instrument socket 801 communicates with the strip groove. One end of the swing arm 802 is fixedly connected to the top rod 703. The other end of the swing arm 802 is located in the strip groove of the instrument socket 801. The top rod 703 is located in the strip groove on the guide seat 10. The strip groove can make way for the top rod 703 during the swing of the swing arm 802.

[0024] The upper detection pressure plate 9 includes a crossbeam and a seat plate. The crossbeam is detachably connected to the base 1. The crossbeam is used to install the seat plate. The seat plate can limit the upper end face of the rear floor front panel assembly. The seat plate is fixedly connected to the crossbeam. The insertion hole is located on the seat plate.

[0025] The working principle of this invention is as follows: In use, the rear floor front panel assembly is first placed along the contour block 2, the first positioning detection seat 5, and the second positioning detection seat 6. Then, the rear floor front panel assembly is pressed tightly using a clamping clamp 4. Next, the rotating bracket 302 is flipped so that the detection insert 303 is flipped above the rear floor front panel assembly. Then, the rotating bracket 302 is fixed to the second hinge seat 301 using screws. Subsequently, a plug gauge is used to check whether the gap between the rear floor front panel assembly and the contour block 2 is qualified. Then, a dial indicator and a plug gauge are inserted into the corresponding detection holes to perform hole and groove detection on the upper surface of the rear floor front panel assembly (when using the dial indicator, observe that the dial indicator is fully inserted). (If the value is within the normal range, then there is a surface defect.) Then, the bottom surface of the rear floor and front panel assembly is inspected. At the first lifting detection component 7, the elastic pusher 704 is pried upward by holding the push rod 703. The elastic pusher 704 will rise to inspect the holes and grooves on the bottom surface of the rear floor and front panel assembly. If the elastic pusher 704 cannot be pried, the hole and groove inspection is unqualified. Next, at the second lifting detection component, a dial indicator is inserted into the detection hole of the instrument socket 801. The swing arm 802 will drive the detection rod 804 upward to inspect the hole and groove under the placement of the dial indicator. If the detection rod 804 can be inserted into the corresponding hole and groove, the inspection is qualified; otherwise, it is unqualified.
