[0002] After the metal workpiece is processed, it is necessary to perform a roughness test on the surface of the metal workpiece to ensure that the quality of the metal workpiece is qualified. In the process of testing the surface roughness of the metal workpiece, people often use a metal surface roughness tester for testing. In the prior art, the workpiece to be tested is generally limited by a threaded clamp. In actual use, the threaded clamp needs to be frequently twisted to clamp or loosen, which wastes a long time and is inconvenient. Therefore, a metal surface roughness detection device is needed to improve the above problem. Utility Model Content

[0003] In order to overcome the above defects, the utility model provides a metal surface roughness detection device, which solves the problem that in actual use, it is necessary to frequently twist the threaded clamp to tighten or loosen it, which wastes a long time and is relatively inconvenient.

[0012] 1. The metal surface roughness detection device is provided with a piston cylinder, a piston frame, a piston rod, a connecting pipe, a movable rod and a limit plate.

[0020] The other end of the connecting pipe 18 is connected with the piston frame 9. Two fixing blocks 2 are provided on the bottom plate 1. Two guide rods 3 are provided in the fixing block 2. A guide hole 4 is opened on the side of the detection platform 12. The guide hole 4 overlaps the guide rod 3. By setting the guide rod 3 and the guide hole 4, the guide rod 3 and the guide hole 4 cooperate with each other, so that the detection platform 12 can slide smoothly. An electric push rod 13 is provided on the bottom plate 1. A connecting block 11 is provided at the output end of the electric push rod 13.

When the piston rod 14 contacts the fixed block 2, the fixed block 2 squeezes the piston rod 14, and the piston rod 14 squeezes the piston plate 15, the first spring 16 is compressed, and the gas inside the piston cylinder 19 is squeezed;

[0023] At this time, the squeezed gas is smoothly transported to the piston frame 9 through the connecting pipe 18, so that the squeezed gas pushes the movable plate 20 and the movable rod 17 to move towards the workpiece until the movable rod 17 drives the limit plate 6 to be in close contact with the workpiece, and finally controls the support rail 10 and the roughness detector 8 to perform detection operations on the workpiece.
