DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] As Figures 1 to 9 shown, the utility model provides a kind of automobile front floor passage upper reinforcement plate assembly gauge, including base 1, workbench 4 and infrared scanner 3, base 1 is rotatably installed with main shaft 101, main shaft 101 is fixedly connected with bearing plate 2, bearing plate 2 is installed with bearing seat 202, bearing seat 202 is rotatably installed with rotating shaft 203, workbench 4 is fixedly connected on rotating shaft 203, counterweight 409 is fixedly connected on the side of workbench 4 away from bearing plate 2.

[0022] When working, to be detected is arranged on workbench 4, and infrared scanner 3 is hung above workbench 4 to detect to-be-detected object.

[0023] In initial state, bearing plate 2 and workbench 4 are parallel to each other, and the axis of main shaft 101 is perpendicular to bearing plate 2 and workbench 4, and base 1 is in horizontal state, and the axis of main shaft 101 is in vertical state.

[0024] When base 1 is located on inclined ground, under the gravity of counterweight 409, bearing plate 2 rotates around main shaft 101, so that counterweight 409 is at the lowest point, so that workbench 4 and bearing plate 2 are parallel to the inclined ground.

[0025] As Figure 6As shown in Figure 7, the workbench 4 is equipped with a fixing structure for fixing the object to be tested. The fixing structure includes multiple internally threaded tubes 401, which are rotatably mounted on the workbench 4. The internal threads of the internally threaded tubes 401 are engaged with studs 402. A housing 403 is fixedly connected to the studs 402. A cylinder 404 is connected to one side of the housing 403. A piston 405 is slidably engaged in the cylinder 404. A second screw 407 is rotatably mounted on the piston 405. A nut seat 406 is fixedly connected to the cylinder 404. The second screw 407 is threadedly engaged in the nut seat 406. A rubber pad 408 is fixedly connected to the end face of the housing 403.

[0026] The object to be tested is placed on the rubber pad 408, and then the second screw 407 is driven to rotate. Since the second screw 407 is threaded in the nut seat 406, when the second screw 407 rotates, it will drive the piston 405 to move axially in the cylinder 404, thereby reducing the pressure in the cylinder 404 and the housing 403. Under the action of the external atmospheric pressure, the object to be tested will be adsorbed on the rubber pad 408 to complete the fixation of the object to be tested.

[0027] By causing the internally threaded tube 401 and the stud 402 to rotate relative to each other, the height of the rubber pad 408 can be adjusted, thereby allowing the rubber pad 408 to come into contact with and adsorb the object to be tested.

[0028] like Figure 3 As shown in Figure 5, a one-way bearing 205 is mounted on the rotating shaft 203. A connecting rod 209 is mounted on the one-way bearing 205 via a connecting structure. The connecting structure includes a sliding sleeve 206, which is slidably fitted onto the one-way bearing 205. A threaded hole 207 is provided on the sliding sleeve 206, and a fixing screw 208 is threaded into the threaded hole 207. The top end of the connecting rod 209 is fixed to the sliding sleeve 206. The connecting structure includes the sliding sleeve 206, which is slidably fitted onto the shaft 203. The connecting rod 209 is mounted on a one-way bearing 205. A threaded hole 207 is provided on the sliding sleeve 206, and a fixing screw 208 is threaded into the threaded hole 207. The top end of the connecting rod 209 is fixed to the sliding sleeve 206. A driving structure is provided on the load-bearing plate 2 to drive the connecting rod 209 to move. The driving structure includes a connecting plate 204, on which a first screw 213 is screwed. A sliding groove 212 is fixed to the screw 213, and the connecting rod 209 slidably fits within the sliding groove 212.

[0029] The sliding sleeve 206 is fixed to the one-way bearing 205 by the fixing screw 208, which allows for easy disassembly or installation of the sliding sleeve 206.

[0030] like Figure 5As shown in Fig. 9, the bottom of the connecting rod 209 is fixedly connected with a pendulum 210, the bearing plate 2 is fixedly connected with a limiting groove 211, the internal shape of the limiting groove 211 is matched with the external shape of the pendulum 210, the bearing plate 2 is fixedly connected with a supporting block 201 to support the workbench 4, the bearing plate 2 is provided with a driving structure to drive the connecting rod 209 to move, the driving structure comprises a connecting plate 204, the connecting plate 204 is screwed with a first screw rod 213, the first screw rod 213 is fixedly connected with a sliding groove 212, and the connecting rod 209 is slidably matched in the sliding groove 212.

[0031] When the bearing plate 2 is inclined, the pendulum 210 drives the connecting rod 209 to rotate on the one-way bearing 205 under the action of gravity, and the rotating shaft 203 will not rotate at this time.

[0032] After the connecting rod 209 rotates, the pendulum 210 is separated from the limiting groove 211, at this time, the first screw rod 213 is driven to rotate, the first screw rod 213 drives the sliding groove 212 to move in the process of rotating due to the threaded cooperation of the first screw rod 213 in the connecting plate 204, and after the sliding groove 212 contacts with the connecting rod 209, the sliding groove 212 drives the connecting rod 209 to rotate reversely.

[0033] Due to the existence of the one-way bearing 205, the connecting rod 209 reversely rotates to drive the rotating shaft 203 to synchronously rotate through the one-way bearing 205, and the rotating shaft 203 rotates to drive the workbench 4 to rotate.

[0034] When the pendulum 210 reversely rotates with the connecting rod 209 and is reset in the limiting groove 211, the workbench 4 is just rotated to the horizontal state, so that the leveling work of the workbench 4 is completed.

[0035] The working principle and use process of the utility model are as follows:

[0036] When working, the to-be-detected object is arranged on the workbench 4, and the infrared scanner 3 is hung above the workbench 4 to detect the to-be-detected object.

[0037] By relatively rotating the inner thread pipe 401 and the stud 402, the height of the rubber pad 408 can be adjusted, so that the rubber pad 408 contacts and adsorbs the to-be-detected object.

[0038] The to-be-detected object is placed on the rubber pad 408, then the second screw rod 407 is driven to rotate, the piston 405 is axially moved in the cylinder body 404 in the process of rotating of the second screw rod 407 due to the threaded cooperation of the second screw rod 407 in the nut seat 406, so that the pressure in the cylinder body 404 and the shell 403 is reduced, and the to-be-detected object is adsorbed on the rubber pad 408 under the action of the external atmospheric pressure, so that the to-be-detected object is fixed.

[0039] In the initial state, the load plate 2 and the workbench 4 are parallel to each other, the axis of the main shaft 101 is perpendicular to the load plate 2 and the workbench 4, the base 1 is in a horizontal state, and the axis of the main shaft 101 is in a vertical state.

[0040] When the base 1 is located on an inclined ground, under the action of the gravity of the counterweight 409, the load plate 2 rotates around the main shaft 101, so that the counterweight 409 is at the lowest point, thereby making the workbench 4 and the load plate 2 parallel to the inclined ground.

[0041] When the load plate 2 is inclined, under the action of gravity, the pendulum 210 drives the connecting rod 209 to rotate on the one-way bearing 205, and at this time, the rotating shaft 203 is not rotated.

[0042] After the connecting rod 209 rotates, the pendulum 210 is separated from the limiting groove 211, at this time, the first screw 213 is driven to rotate, since the first screw 213 is threadedly matched in the connecting plate 204, the first screw 213 rotates to drive the sliding groove 212 to move, until the sliding groove 212 contacts the connecting rod 209, the sliding groove 212 drives the connecting rod 209 to rotate reversely.

[0043] Since the one-way bearing 205 exists, when the connecting rod 209 reversely rotates, the one-way bearing 205 drives the rotating shaft 203 to synchronously rotate, the rotating shaft 203 rotates to drive the workbench 4 to rotate.

[0044] When the pendulum 210 reversely rotates with the connecting rod 209 and is reset in the limiting groove 211, the workbench 4 is just rotated to the horizontal state, thereby completing the leveling work of the workbench 4.

[0045] After the detection work on the to-be-detected object is completed, the fixing screw 208 is opened to enable the rotating shaft 203 to freely rotate, at this time, the rotating shaft 203 is manually rotated to enable the workbench 4 to abut against the supporting block 201; then, the first screw 213 is driven to rotate and the sliding groove 212 is reset, and the fixing screw 208 is locked again, thereby completing the resetting work of the device.

[0046] Compared with the prior art, the gravity of the counterweight 409 is used to rotate the workbench 4 and the load plate 2 on the base 1, so as to find the inclined direction of the ground, the connecting rod 209 is reversely driven to rotate the rotating shaft 203, thereby driving the workbench 4 to rotate to the horizontal position through the rotating shaft 203, so as to ensure that the infrared scanner 3 can horizontally scan and detect the to-be-detected object, thereby reducing the error of the measured data.
