[0022] In the embodiment, a driving groove 205 is provided on the top surface of the detection platform 1, a first motor is fixed on the right side of the detection platform 1, the output shaft of the first motor passes through and extends to the interior of the driving groove 205, a first bidirectional screw rod 206 is fixed to the output shaft of the first motor, the clamping plate 2 is threadedly connected to the outer wall of the first bidirectional screw rod 206, a second motor is fixed to the rear side of the clamping plate 2, the output shaft of the second motor passes through and extends to the interior of the adjusting groove 201, a second bidirectional screw rod 207 is fixed to the output shaft of the second motor, the movable bar 202 is threadedly connected to the outer wall of the second bidirectional screw rod 207, a support frame 208 is fixed to the top surface of the clamping plate 2, an electric push rod is fixed to the top surface of the support frame 208, one end of the telescopic rod of the electric push rod passes through and extends to the bottom surface of the support frame 208, and one end of the telescopic rod of the electric push rod is fixed There is a linkage frame 209, and the movable bar 202 and the outer wall of the linkage frame 209 are slidably arranged. Two limit rods 210 are fixed to the bottom surface of the linkage frame 209, and the pressure plate 204 and the outer wall of the limit rod 210 are slidably arranged. The metal product to be inspected is clamped and positioned by setting the clamping plate 2, and then the pressure plate 204 is used to press down on the top surface of the metal product, so as to press the metal product, so that the bottom of the metal product is closely fitted with the top surface of the detection table 1, thereby increasing the accuracy of flatness detection. At the same time, during the mobile detection process of the detector 101, the pressure plate 204 can be avoided according to the position of the detector 101, and the pressing force of the metal product will not disappear during the avoidance process, thereby ensuring that the surface of the detector 101 is fully detected, making the flatness detection of the metal product more comprehensive.

[0023] In the embodiment, a directional wheel 3 is fixed to the bottom surface of the pressure plate 204, and the directional wheel 3 presses the surface of the metal product so that when the pressure plate 204 drives the directional wheel 3 to move, the surface of the metal product will not be scratched, thereby preventing damage to the metal product.

[0024] In the embodiment, a connecting frame 4 is fixed to the top surface of the detection platform 1, and a gantry slide 401 is fixed to the top surface of the connecting frame 4. The detection instrument 101 and the mounting end of the gantry slide 401 are detachably fixed. Through the setting and use of the gantry slide 401, the detection instrument 101 can be driven to move forward, backward, left, right, up and down, so as to realize all-round detection of the surface of the metal product.

[0025] In the embodiment, the top surface of the testing platform 1 is provided with material taking troughs 5 near the front and rear sides. The provision and use of the material taking troughs 5 facilitates the staff to take the tested metal products off the testing platform 1 in a better manner.

[0026] In the embodiment, anti-skid grooves 6 are provided on both sides of the two clamping plates 2 close to each other. By setting and using the anti-skid grooves 6, the friction between the clamping plates 2 and the metal products can be increased, so that the clamping plates 2 can fix the metal products more tightly.

[0027] Working principle: When in use, the metal product that needs to be tested for flatness is placed on the top surface of the testing table 1, and then the first motor is started to drive the first bidirectional screw 206 to rotate. Under the action of the threaded connection of the outer wall of the first bidirectional screw 206 of the clamping plate 2, the two clamping plates 2 are respectively fitted with the two sides of the metal product. At this time, the second motor is started to drive the second bidirectional screw 207 to rotate. Under the action of the threaded connection between the movable bar 202 and the second bidirectional screw 207, the four movable bars 202 are respectively moved to the top of the four corners of the metal product. During the movement of the movable bar 202, the pressure plate 204 is driven to move. During this process, the pressure plate 204 slides on the outer wall of the limit rod 210. Then the electric push rod is started to drive the linkage frame 209 and the pressure plate 204 to move downward. At this time, the directional wheel 3 on the bottom of the pressure plate 204 is in contact with the top surface of the metal product and presses the metal product. Then the first motor is started to drive the two clamping plates 2 to clamp the metal product tightly. Then the gantry slide 401 can be started to drive the detector 101 to move forward, backward, left, right, up and down, so as to achieve all-round detection of the surface of the metal product. When the detector 101 moves to the position corresponding to the directional wheel 3, the second motor is started to drive the two movable bars 202 to drive the directional wheel 3 to move on the top surface of the metal product and avoid the detector 101, thereby completing the detection of the flatness of the metal product surface.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
