[0020] See also Figure 1-5 The utility model provides a technical solution: a roller surface hardness detection device, including a concave fixed frame 1, a first servo motor 2 is provided inside the concave fixed frame 1, and one end of the output shaft of the first servo motor 2 is connected to a first screw 3 through a coupling, a driving gear is sleeved on the first screw 3, and a driven gear is correspondingly provided on one side of the driving gear, a transmission belt 6 is sleeved on the outer wall of the driving gear and the driven gear, and the first screw 3 is also inserted inside the driven gear, a first slide bar 4 is correspondingly provided on the outer side of the first screw 3, and two groups of first movable blocks 5 are respectively inserted on the first screw 3 and the first slide bar 4. It should be additionally explained that the inner wall of the transmission belt 6 is provided with internal teeth meshing with the outer walls of the driving gear and the driven gear, so as to ensure that the driving gear can drive the driven gear to move synchronously through the transmission belt 6.

[0021] Furthermore, a linkage structure is formed between the first screw 3 through a driving gear, a driven gear, and a transmission belt 6, and the first movable block 5, under the action of the first servo motor 2, forms a limited sliding structure through the first screw 3, the first sliding rod 4 and the concave fixed frame 1, so that the limiting components of the two groups of rollers 11 can be replaced back and forth, thereby increasing the loading and unloading speed of the rollers 11 during the detection process.

[0022] The first movable block 5 is provided with an electric push rod 7 at the bottom, and the electric push rod 7 is provided with a telescopic arm 8 on the opposite surface. The other end of the telescopic arm 8 is connected to the fixed block 10, and a vacuum suction cup 9 is inserted in the fixed block 10. A rolling roller 11 is placed between the vacuum suction cups 9. It should be additionally explained that a connecting tube is provided on the vacuum suction cup 9, and the other end of the connecting tube is connected to a vacuum device. During the operation of the vacuum suction cup 9, suction can be performed by the vacuum device to generate a negative pressure in the vacuum suction cup 9, so as to adsorb the rolling roller 11. After the inspection of the rolling roller 11 is completed, the vacuum suction cup 9 is inflated to make the interior of the vacuum suction cup 9 become zero air pressure or positive air pressure, thereby making the vacuum suction cup 9 detach from the rolling roller 11.

[0023] Furthermore, under the action of the electric push rod 7, the vacuum suction cup 9 forms a horizontal pushing structure with the roller 11 through the telescopic arm 8, and the roller 11 forms a rotating structure through the vacuum suction cup 9 and the fixed block 10, so that the roller 11 is adsorbed and limited by the vacuum suction cup 9, and the limiting effect of the vacuum suction cup 9 on the roller 11 is increased by the electric push rod 7.

[0024] The concave fixing frame 1 is respectively provided with an L-shaped support rod 12 on the upper end surface, and the upper end of the L-shaped support rod 12 is connected to the fixing frame 13, the fixing frame 13 is internally provided with a second servo motor 14, and one end of the output shaft of the second servo motor 14 is connected to the second screw 15 through a coupling, the second screw 15 is correspondingly provided with a second slide bar 16 at the rear, and the second screw 15 and the second slide bar 16 are interspersed with a second movable block 17, the second movable block 17 is connected to the operating head at the bottom, and the operating head is connected to a connecting plate 18 at the lower end, and the connecting plate 18 is provided with a hardness detection head 19 on the lower end surface.

[0025] Furthermore, under the action of the second servo motor 14, the second movable block 17 forms a limited sliding structure through the second screw 15, the second slide rod 16 and the fixed frame 13, so that the hardness of the roller 11 is detected at multiple positions through the sliding hardness detection head 19, thereby ensuring the accuracy of the hardness detection data of the roller 11 by the device.

[0026] The two ends of the hardness testing head 19 are respectively provided with hollow rods 20 on the connecting plate 18, and a telescopic rod 21 is inserted into the hollow rod 20. A spring 22 is provided inside the hollow rod 20, and the other end of the spring 22 is connected to the inside of the telescopic rod 21. A rubber block 23 is provided at the lower end of the telescopic rod 21.

[0027] Furthermore, the rubber block 23 forms an elastic telescopic structure through the telescopic rod 21, the spring 22 and the hollow rod 20, so that the force applied to the hardness testing head 19 during operation is buffered by the elastic telescopic assembly.

[0028] Working principle: When using the roller surface hardness detection device, first place the roller 11 between one of the groups of vacuum suction cups 9, so that the two groups of vacuum suction cups 9 are attached to the two ends of the roller 11 through the electric push rod 7 to adsorb and limit it. After the current roller 11 is limited, the hardness detection head 19 can be driven to descend by the operating head to detect the hardness of the surface of the roller 11. At the same time, the other group of rollers 11 are limited and fixed in the same way, so that the device can continue to detect the hardness of the roller 11; during the hardness detection process of the roller 11, the rubber block 23 first contacts the roller 11, and the telescopic rod 21 is retracted into the hollow rod 20 through the spring 22, so as to buffer the force applied to the hardness detection head 19 during its operation, thereby increasing the service life of the hardness detection head 19, and the hardness detection head 19 can start the second servo motor 14 during use, so as to detect the hardness of the roller 11 through the second screw 15 and the first The second slide bar 16 drives the second movable block 17 to slide in a limited position, so that the sliding hardness detection head 19 can detect multiple surfaces of the roller 11, thereby increasing the accuracy of the device's hardness detection data of the roller 11; after the current roller 11 detection is completed, the first servo motor 2 can be started, and the first servo motor 2 drives the first movable block 5 to slide in a limited position by the same principle, thereby driving the roller 11 to rotate and move, so as to switch the position of the roller 11, and thus facilitate the hardness detection of the next group of rollers 11. During the movement of the roller 11, the electric push rod 7 applies a small force to the vacuum suction cup 9, thereby ensuring that the roller 11 rotates and moves through the vacuum suction cup 9. During the hardness detection of the roller 11, the electric push rod 7 increases the force on the vacuum suction cup 9, thereby ensuring the stability of the roller 11 during the hardness detection process. This is the use process of the roller surface hardness detection device.
