DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] The integrated detection device for dynamic balance and disturbance of a rolling mill comprises: a workbench 10; a limit assembly 40, which is provided with two groups and is respectively fixedly arranged at the two ends of the workbench 10 for clamping the rolling mill, and the limit assembly 40 is provided with a detection component 1 to detect the dynamic balance of the rolling mill when rotating; a moving module 20, which is arranged on the workbench 10 and is located on one side of the limit assembly 40; a detection assembly 30, which is arranged on the moving module 20, and the detection assembly 30 is provided with two groups of moving plates 32, one group of the moving plates 32 is provided with a marking unit 33, and the other group of the moving plates 32 is provided with a detection component 2 for detecting the disturbance of the rolling mill, the detection head of the detection component 2 faces the rolling mill to be tested, the rolling mill is driven to rotate by an external force, and the moving module 20 drives the detection component 30 to move axially along the surface of the rolling mill, thereby realizing the disturbance measurement of the rolling mill at any position of the roller body.

[0030] In the present invention, two sets of limit assemblies 40 are clamped at the ends of the rollers so that the rollers are installed in a horizontal state as a whole, so as to detect the disturbance and dynamic balance of the rollers. At the same time, the movable module 20 cooperates with the detection assembly 30 to measure the disturbance at any position of the roller body of the roller, which is more flexible. When the limit assembly 40 clamps the ends of the rollers, the dynamic balance of the rollers can be detected by the detection member 1 when the rollers rotate. By integrating the dynamic balance and disturbance detection together, repeated installation and disassembly of equipment can be avoided, thereby significantly reducing the detection time. Multiple tests can be completed in one installation, which improves the work efficiency and thus improves the production efficiency of the rollers.

[0031] In one embodiment, reference Figure 1 and Figure 3 The limiting assembly includes a fixed frame 47, a fixed plate 41 is fixedly arranged on the fixed frame 47, two groups of support rollers 42 are rotatably connected to the fixed plate 41, a fixed cylinder 44 is threadedly connected to the top of the fixed frame 47, a movable rod 46 is movably inserted at the bottom of the fixed cylinder 44, and the bottom of the movable rod 46 is rotatably connected to the limiting roller 43, and a space for the roller end to be limited and carried is formed between the two support rollers 42 and the limiting roller 43;

[0032] Placing the end of the roller in the carrying space formed between the support roller 42 and the limit roller 43 and limiting the end of the roller can effectively prevent the roller from rolling to other areas after detaching from the limit assembly 40, thereby improving the safety of workers when measuring the dynamic performance values ​​of the roller. The rotating support roller 42 can reduce the friction between the roller and the roller, thereby improving the accuracy of dynamic balance detection. When the vibration force of the roller is large, the movable rod 46 will be pushed upward through the limit roller 43 to contact the detection piece for detection.

[0033] In one embodiment, reference Figure 3 The detection part 1 includes a pressure sensor 45, and the pressure sensor 45 is arranged on the top of the inner wall of the fixed cylinder 44. The top of the movable rod 46 contacts the force application point of the pressure sensor 45 to detect the dynamic balance of the roller during rotation. When the roller is tested, the vibration of the roller will be transmitted to the movable rod 46, and the movable rod 46 will apply pressure to the pressure sensor 45 through its top. The greater the amplitude of the vibration of the movable rod 46, the greater the pressure on the pressure sensor 45, thereby detecting the vibration of the roller. According to the detection of the pressure sensor 45, it is determined whether the dynamic balance of the roller is controlled within a certain range.

[0034] In one embodiment, the detection assembly 30 also includes a mounting bracket 31 and a fixed frame perpendicular to the mounting bracket 31, the mounting bracket 31 is slidably connected with two groups of sliding sleeves 36, the two groups of sliding sleeves 36 are fixedly connected with the two groups of movable plates 32 in a one-to-one correspondence, a cylinder 35 is arranged on the fixed frame, the output end of the cylinder 35 is rotatably connected with two groups of connecting rods 37, the two groups of connecting rods 37 are rotatably connected with the two groups of sliding sleeves 36 in a one-to-one correspondence, when the piston rod of the cylinder 35 is extended, the two groups of sliding sleeves 36 are driven to move away from each other through the two groups of connecting rods 37, so as to facilitate the installation or disassembly of the roller, when the roller is installed, the piston rod of the cylinder 35 retracts, and the two groups of sliding sleeves 36 are driven to move towards each other through the two groups of connecting rods 37, so as to make the marking unit and the second detection component contact with the roller, so as to facilitate subsequent detection.

[0035] In order to prevent the sliding sleeve 36 from deflecting during the movement, refer to Figure 3 The mounting bracket 31 is provided with a convex strip, and the sliding sleeve 36 is provided with a groove matched with the convex strip. The convex strip and the groove (not shown in the figure) cooperate with each other to provide a guiding effect for the movement of the sliding sleeve 36.

[0036] In one embodiment, reference Figure 3 The second detection component includes a micrometer 34 arranged on the movable plate 32 and a probe arranged on the micrometer 34. The extension direction of the probe is perpendicular to the central axis of the roller. The roller is driven to rotate, and the movable module 20 drives the detection component to move along the length direction of the roller. The probe can be moved along the axis of the roller. The pointer of the micrometer on the entire axis changes to judge the disturbance error.

[0037] In order to facilitate subsequent correction, refer to Figure 5 , Figure 6 as well as Figure 7The marking unit 33 also includes a cylinder 331 with liquid storage arranged on the movable plate 32, a partition 332 is arranged in the cylinder 331, and the partition 332 divides the cavity of the cylinder 331 into cavity 1 and cavity 2 from top to bottom. A fixed tube 333 is fixedly arranged at the center of the cylinder 331 and along its extension direction, and a moving rod 338 is movably inserted in the fixed tube 333, and a flow channel 3381 for liquid flow is arranged in the moving rod 338. The surface of the fixed tube 333 is provided with a second through hole 335 and a first through hole 334 in the cavity 1 and the cavity 2, respectively. The side wall of the moving rod 338 is provided with a second connecting hole 337 and a first connecting hole 336 in communication with the flow channel 3381 from top to bottom. The top of the moving rod 338 penetrates the fixed tube 333 and extends to the outside of the fixed tube 333. An expanded end is integrally formed, and a spring 339 is wound around the surface of the moving rod 338 and located between the expanded end and the cylinder 331.

[0038] Different colors of pigments are placed in cavity 1 and cavity 2 respectively. In the initial state, through hole 1 334 and connecting hole 1 336 are disconnected, and through hole 2 335 and connecting hole 2 337 are disconnected. When the end of the moving rod 338 contacts the surface of the roller, when the roller body pushes the moving rod 338, when the disturbance deviation at this position of the roller body exceeds the first preset value (i.e., the first state), refer to Figure 5 At this time, the through hole 1 334 is connected to the connecting hole 1 336, while the through hole 2 335 is disconnected from the connecting hole 2 337, so that the pigment in the cavity 2 enters the flow channel 3381 through the through hole 1 334 and the connecting hole 1 336, then flows along the flow channel 3381, and finally is discharged from the end of the moving rod 338. When the disturbance deviation at this position of the roller body exceeds the second preset value (i.e., the second state), refer to Figure 6 At this time, through hole 1 334 is connected with connecting hole 1 336, and through hole 2 335 is connected with connecting hole 2 337, so that the pigment in cavity 2 enters the flow channel through through hole 1 334 and connecting hole 1 336, and the pigment in cavity 1 enters the flow channel through through hole 2 335 and connecting hole 2 337, so that the pigments in cavity 1 and cavity 2 are mixed to form other colors, and then flow along flow channel 3381, and finally discharged from the end of moving rod 338. When the disturbance deviation at this position of the roller body exceeds the third preset value (i.e., the third state), refer to Figure 7 At this time, through hole 1 334 and connecting hole 1 336 are disconnected, while through hole 2 335 and connecting hole 2 337 are connected, so that the pigment in cavity 1 enters flow channel 3381 through through hole 2 335 and connecting hole 2 337, then flows along flow channel 3381, and finally is discharged from the end of moving rod 338. Different colors of pigments can be sprayed on the parts where the disturbance deviation exceeds the required range, and pigment marking is realized, so as to facilitate the smooth progress of the subsequent correction work.

[0039] In one embodiment, the distance between the second through hole 335 and the second connecting hole 337 is greater than the distance between the first through hole 334 and the first connecting hole 336 .

[0040] In one embodiment, a driving member 50 is also included, and the driving member includes a motor arranged on the workbench 10. A transmission belt is connected between the output shaft of the motor and the roller. When the motor is started, the motor drives the roller to rotate through the transmission belt, which is convenient for dynamic balance and disturbance detection.
