DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further explained and illustrated by means of specific embodiments below.

[0019] As attached Figure 1 As shown, an embodiment of the present application provides an offline high-precision copper and copper alloy strip rolling roller accuracy detection system, which includes a load-bearing platform 1, a first rotating base 2, a second rotating base 3, and a dial indicator fixture 4. The load-bearing platform 1 is a component on which the first rotating base 2, the second rotating base 3, the dial indicator fixture 4, and the rollers 5 are mounted. It is formed by welding profile materials and is a load-bearing frame with strong deformation and yield resistance.

[0020] The first rotating body 2 and the second rotating body 3 are components for bearing and rolling the roller 5, and both are arranged on the load-bearing platform 1. Specifically, the inner ring of the bearing of the roller 5 is arranged in the first rotating body 2 and the second rotating body 3, so that the roller 5 can rotate relative to the axis of the first rotating body 2 and the second rotating body 3 through the inner ring of the bearing.

[0021] To ensure that the offline high-precision copper and copper alloy strip rolling roll accuracy inspection system is adaptable to rolls 5 of varying sizes, a first movable support plate 13 and a second movable support plate 14 are adjustable on the load-bearing platform 1 via positioning bolts 17. The first rotating base 2 is mounted on the first movable support plate 13, and the second rotating base 3 is mounted on the second movable support plate 14. Both the first and second movable support plates 13, 14 are provided with strip-shaped holes, through which positioning bolts 17 secure the first and second movable support plates 13, 14 to the load-bearing platform 1.

[0022] When measuring the rolling tolerance of the roller 5, the first movable support plate 13 and the second movable support plate 14 are placed on the load-bearing platform 1 according to the roller surface height of the roller 5 to be measured, and the distance between the two is adjusted to achieve the adjustment of the distance between the first rotating seat body 2 and the second rotating seat body 3, and then the corresponding roller 5 is placed.

[0023] The dial indicator fixture 4 is a component for measuring the rolling tolerance of the roller 5 and is installed on the load-bearing platform 1. The dial indicator fixture 4 is provided with a dial indicator 8, which is attached to the roller surface of the roller 5 to facilitate the measurement of the circular runout value of the roller surface of the roller 5 during the rolling process of the roller 5, thereby realizing the measurement of the rolling tolerance.

[0024] In the embodiment of the present application, the dial indicator fixing device 4 includes a strip bottom plate 401, a fixing plate 402 horizontally slidingly arranged on the strip bottom plate 401, and a dial indicator 8 vertically slidingly arranged on the fixing plate 402. Figure 2 Specifically, the strip bottom plate 401 is a long strip-shaped component that is installed in a threaded hole on the load-bearing platform 1. A slide groove 403 is provided on the strip bottom plate 401, and a slider 404 is provided at the bottom of the fixed plate 402. The slider 404 is placed in the slide groove 403 to enable the fixed plate 402 to slide horizontally on the strip bottom plate 401. To prevent the fixed plate 402 from slipping out of the slide groove 403 when sliding horizontally on the strip bottom plate 401, a pressure plate 405 is provided below the slider 404. The width of the pressure plate 405 is greater than the width of the slide groove 403.

[0025] In addition, in the vertical direction, a through slot 406 is provided on the fixed plate 402, and a micrometer 8 is slidably set in the through slot 406. Therefore, the micrometer 8 can be set at any position of the fixed plate 402 through the through slot 406, thereby realizing the measurement of the roller surface circular runout value of the roller 5.

[0026] Furthermore, to facilitate the vertical arrangement of the through slot 406 and the horizontal sliding arrangement within the slide slot 403, the fixed plate 402 is an L-shaped fixed plate or a bent fixed plate. Preferably, the dial gauge 8 in the embodiment of the present application is a self-locking digital dial gauge, which can be locked to the fixed plate 402 in a self-locking manner, and at the same time facilitates the simple measurement of rolling tolerances through reading.

[0027] In the embodiment of the present application, in order to realize the rotation of the roller 5, a reducer 7 is further provided on the load-bearing platform 1, and the reducer 7 is connected to the shaft end of the roller 5 through the adjustment screw 6. Figure 3 Specifically, a dial ring 9 is provided on the shaft end of the roller 5, and a rotating coupling disk 10 is provided on the output shaft of the reducer 7. The rotating coupling disk 10 and the dial ring 9 are connected by an adjusting screw 6. Therefore, when the reducer 7 as the power end rotates, the roller 5 can be driven to rotate through the rotating coupling disk 10, the adjusting screw 6, and the dial ring 9.

[0028] Furthermore, a plurality of slots 11 are provided on the rotating coupling disk 10, and the adjusting screw 6 is fixed in the slot 11 through the adjusting nut 12, so that the rotating diameter of the roller 5 can be adjusted up and down in the slot 11 according to the size of the axial end of the roller 5, thereby driving the roller 5 to rotate.

[0029] To increase the stability of the reducer 7 during operation, the load-bearing platform 1 is further provided with a reducer base 15, on which the reducer 7 is mounted. To facilitate rotation of the reducer 7, a corrugated handwheel 16 is also provided on the reducer 7, allowing the operator to manually operate the reducer 7. The reducer 7 in the embodiment of the present application is a cycloid pinwheel reducer, which is a high-transmission-ratio power output device.

[0030] The working process of the offline high-precision copper and copper alloy strip rolling roller accuracy detection system in the embodiment of the present application is as follows: Place the roller 5 horizontally between the first rotating body 2 and the second rotating body 3, and adjust the rolling elements of the rotating body to support the bearings of the roller 5. Open the positioning nuts 17, and adjust the positions of the first and second movable support plates 13 and 14 by measuring the positions of the first and second rotating bodies 2 and 3, so that the bearings of the roller 5 can rest on the first and second rotating bodies 2 and 3. After tightening the positioning nuts 17, place the adjusted first and second rotating bodies 2 and 3, and the roller 5 above the first and second movable support plates 13 and 14.

[0031] Install the dial ring 9 on the shaft end of the roller 5 and fix it, rotate the adjusting nuts 12 on both sides counterclockwise to loosen the adjusting screw 6, move the adjusting screws 6 on both sides in the slots 11 of the rotating coupling disk 10, so that the adjusting screws 6 on both sides are close to the shaft end side of the roller 5 and are respectively close to the dial ring 9, and rotate the adjusting nuts 12 on both sides clockwise to fix the adjusting screws 6.

[0032] Loosen the fastening bolts on both sides of the strip base plate 401, adjust the dial indicator fixture 4 so that the needle of the dial indicator 8 is close to the roller body 5, and then tighten the fastening bolts on both sides of the strip base plate 401. Adjust the vertical position of the dial indicator 8 so that the dial indicator 8 slides within the through slot 406 of the fixing plate 402, and align the needle with the most convex point on the horizontal side of the roller body 5. The longitudinal position adjustment is now complete. According to the measurement requirements, move the slide 404 and the pressure plate 405, and align the needle of the dial indicator 8 with the left end, middle, and right end of the roller body of the roller 5, respectively, to select three points. Manually rotate the corrugated handwheel 16 and the reducer 7 to rotate the roller 5. After one rotation, record the fluctuation value of the dial indicator 8. After the measurement is completed, confirm whether the roundness of the roller 5 is qualified and how to adjust the proportions based on the recorded value.

[0033] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
