[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0030] like Figure 1-5As shown, this embodiment provides a fixture for detecting the flatness of a large automobile plate surface, comprising a base plate 1, a detection mechanism 2 is provided on the top of the base plate 1, and an adjustment component 3 is provided on one side of the detection mechanism 2;

[0031] like Figure 3 and Figure 4 As shown, the detection mechanism 2 includes a support portion 201, a first screw rod 202, a clamping portion 203, a vertical plate 204, a connecting plate 205, an annular portion 206, a slide groove 207, a slider 208 and a laser sensor 209. The support portion 201 is bolted to the top of the base plate 1, the first screw rod 202 is threadedly connected to the inside of the support portion 201, the clamping portion 203 is rotatably connected to one end of the first screw rod 202, the vertical plate 204 is bolted to the top of the base plate 1, the connecting plate 205 is arranged on one side of the vertical plate 204, and the annular portion 206 is screwed to the inside of the support portion 201. 06 is bolted to the side wall of the connecting plate 205, the annular portion 206 is located directly above the vehicle disk to be detected, the slide groove 207 is opened at the bottom of the annular portion 206, the slide groove 207 is arranged along the circumference of the annular portion 206, and the slide groove 207 is coaxial with the annular portion 206, the slide groove 207 is a T-shaped groove, and the slider 208 is a shape that matches the T-shaped groove. The slider 208 is slidably connected to the inside of the slide groove 207, and the bottom of the slider 208 extends to the outside of the slide groove 207. The laser sensor 209 is bolted to the bottom of the slider 208. There are two supporting parts 201, first screw rod 202 and clamping part 203, which are arranged opposite to each other. The shape of the clamping part 203 is semicircular. The two clamping parts 203 can be close to each other to form a complete circle, or they can be far away from each other to form enough space for placing the car's large plate. The supporting part 201 is in the shape of an arc plate. The two supporting parts 201 are symmetrical about the center of the clamping part 203. A threaded hole is provided at the center of the arc length direction of the supporting part 201. The first screw rod 202 is installed in the threaded hole. The central axis of the first screw rod 202 passes through the diameter of the clamping part 203. One end of the first screw rod 202 is against the outer wall of the middle section of the clamping part 203 in the arc length direction. A rotating handle is fixed to the other end of the first screw rod 202 located on the side of the supporting part 201 facing away from the clamping part 203. When in use, place the car plate between the two clamping parts 203, then rotate the two first screw rods 202, so that the two clamping parts 203 clamp the car plate, thereby limiting the car plate, and then manually push the laser sensor 209 to make the slider 208 slide inside the slide groove 207. The laser sensor 209 works by emitting a laser beam and receiving the light signal reflected back. When the laser beam shines on the surface of the car plate, the reflected light signal will change. These changes are captured by the laser sensor 209 and converted into electrical signals. By processing these electrical signals, the laser sensor 209 can calculate the flatness of the surface of the car plate, thereby performing all-round detection of the car plate.

[0032] like Figure 3As shown, the adjustment component 3 includes an adjustment slot 301, a motor 302 and a second screw rod 303. The adjustment slot 301 is vertically opened on the side wall of the vertical plate 204, the motor 302 is bolted to the side wall of the vertical plate 204, and the second screw rod 303 is coaxially arranged at the output end of the motor 302. The second screw rod 303 is vertical, and one end of the connecting plate 205 extends to the interior of the adjustment slot 301 and is slidingly connected to the adjustment slot 301. The motor 302 can drive the second screw rod 303 to rotate. One end of the second screw rod 303 passes through the connecting plate 205 and is threadedly connected to the connecting plate 205. The bottom end of the second screw rod 303 is rotatably connected to the top of the base plate 1. When in use, the motor 302 drives the second screw rod 303 to rotate, thereby causing the connecting plate 205, the annular portion 206 and the laser sensor 209 to descend, reducing the time required for the laser sensor 209 to capture the laser beam.

[0033] like Figure 1 As shown, an arc-shaped portion 4 is provided on the top of the base plate 1, and the number of the arc-shaped portions 4 is several. The annular portion 206 is projected with a center on the upper surface of 1, and all the arc-shaped portions 4 are distributed in a circle around the center, and the diameter of the circle formed by connecting the outer walls of all the arc-shaped portions 4 is the same as the inner diameter of the car plate. When in use, the outer wall of the arc-shaped portion 4 fits with the inner circle of the car plate, thereby determining the position of the car plate, which is convenient for the clamping portion 203 to accurately clamp the car plate.

[0034] like Figure 5 As shown, a support ring 5 is provided on the outer side of the arc-shaped portion 4 for facilitating the removal of the car's pan. The support ring 5 is made of stainless steel. When in use, the car's pan is placed on the support ring 5, which can create a distance between the car's pan and the surface of the base plate 1, making it convenient to remove the car's pan from the base plate 1.

[0035] like Figure 1 As shown, a storage frame 6 is bolted to the bottom of the base plate 1, and a sealing plate 7 is hinged on the side wall of the storage frame 6. When in use, the storage frame 6 can store tools used for inspecting the car's disk to keep the top of the base plate 1 clean.

[0036] like Figure 1 As shown, four supporting legs 8 are bolted to the bottom of the base plate 1. The four supporting legs 8 are respectively located at the four corners of the base plate 1. When in use, the supporting legs 8 can support the base plate 1 so that the base plate 1 is at a certain height from the ground, making it convenient for workers to operate the device.

[0037] Specifically, when the present automobile plate surface flatness detection fixture is used: the inner ring of the automobile plate is moved downward along the outer wall of the arc-shaped portion 4 until the bottom of the automobile plate contacts the top of the support ring 5, and then the motor 302 and the laser sensor 209 are connected to the external power supply, and then the two first screw rods 202 are rotated, so that the two clamping parts 203 clamp the automobile plate, thereby limiting the automobile plate, and then manually push the laser sensor 209 to make the slider 208 slide inside the slide groove 207, and the laser sensor 209 emits laser light. The laser sensor 209 works by receiving the light signal reflected from the laser beam. When the laser beam hits the surface of the car plate, the reflected light signal will change. These changes are captured by the laser sensor 209 and converted into electrical signals. By processing these electrical signals, the laser sensor 209 can calculate the flatness of the surface of the car plate, thereby performing a full-scale inspection of the car plate. After the inspection is completed, the first screw rod 202 is rotated in the opposite direction to disengage the clamping part 203 from the car plate, and then the inspected car plate is removed and replaced with the next car plate that needs to be inspected.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
