[0001] This utility model relates to the technical field of roughness detection devices, and in particular to a surface roughness detection device for cold rolling rolls of titanium strip. Background Technology

[0002] In the cold rolling process of titanium strip coils, the surface roughness of the rolls directly affects the surface roughness and quality of the finished titanium strip coil. The roll width of large-coil, wide-width titanium strip coil mills is generally over 1000mm. After a certain amount of rolling, the roundness and surface roughness of the rolls will change. Currently, the method for detecting the surface roughness of the rolls is to manually hold a surface roughness meter and randomly select points at both ends and the middle of the roll surface for testing.

[0042] Reference Figures 1 to 3 This utility model discloses a surface roughness detection device for a titanium strip coil cold rolling roll 500, comprising a sleeve assembly 100, a support assembly 200, and a detection device 300. The sleeve assembly 100 is used to mount the roll 500, the support assembly 200 is mounted on the sleeve assembly 100, and the detection device 300 is mounted on the support assembly 200. The detection device 300 is used to detect the surface roughness of the roll 500. Specifically, refer to... Figure 1 , Figure 2As shown, the sleeve assembly 100 has a through hole 111 axially penetrating the sleeve assembly 100, through which the roll 500 passes. The sleeve assembly 100 can rotate around its own axis. The support assembly 200 includes a telescopic rod group 210, a first support 220, and a second support 230. The first support 220 connects the telescopic rod group 210 and the second support 230. The telescopic rod group 210 is connected to the sleeve assembly 100 and extends radially toward the sleeve assembly 100. The telescopic rod group 210 telescopically drives the second support 230 to move relative to the roll 500. The detection device 300 is mounted on the second support 230. In this embodiment, the detection device, by mounting the support assembly 200 on the sleeve assembly 100 for mounting the detection device 300, enables the detection device 300 to perform circumferential detection on the surface of the roll 500 when the sleeve assembly 100 rotates around its own axis. This results in comprehensive and efficient detection, greatly reducing human interference and improving the accuracy of the detection results.

[0043] The testing equipment 300 mentioned in this embodiment can be purchased from existing equipment according to actual needs, and is not limited in this embodiment.

[0044] The sleeve assembly 100 of this embodiment includes a first sleeve 110, a through hole 111 is provided in the first sleeve 110, a bearing 112 is preferably installed in the through hole, and preferably the bearings 112 are installed at both ends of the through hole 111 in the length direction. The roller 500 passes through the bearings 112 to improve the smoothness of the rotation of the sleeve assembly 100 relative to the roller 500.

[0045] It is conceivable that a support rod could be installed inside the through hole 111, with the support rod extending axially out of the first sleeve 110 and connecting to the roll 500. This would eliminate the need for frequent insertion and removal of the roll 500 from the first sleeve 110, improving the efficiency of roll 500 installation and removal, and thus improving inspection efficiency. At the same time, the method of connecting the roll 500 to the support rod also facilitates the inspection device of this application to inspect rolls 500 with different outer diameters, thus expanding the applicability of this application.

[0046] In the embodiments of this utility model, reference is made to Figure 2As shown, the telescopic rod assembly 210 includes a fixed rod 211, a movable rod 212, and a locking member 213. The movable rod 212 is slidably mounted on the fixed rod 211, and the locking member 213 is used to lock the relative positions of the fixed rod 211 and the movable rod 212. The fixed rod 211 is connected to the sleeve assembly 100, and the first bracket 220 is connected to the movable rod 212. Specifically, the sleeve assembly 100 is provided with a radially protruding mounting seat 122, and the fixed rod 211 is connected to the mounting seat 122 by fasteners such as bolts; the locking member 213 can be a bolt or similar structure. By extending and retracting the telescopic rod assembly 210, the distance between the bracket assembly 200 and the sleeve assembly 100 can be adjusted, thereby adjusting the distance between the detection device 300 and the roll 500. When the outer diameter of the detected roll 500 changes, the position of the detection device 300 can be adjusted by extending and retracting the telescopic rod assembly 210. The adjustment method is simple and highly reliable.

[0047] It is conceivable that in this embodiment... Figure 2 The telescopic rod assembly 210 shown in the example uses manual adjustment to adjust the extension length of the movable rod 212. In actual production, electric, pneumatic, hydraulic or other methods can also be used to realize the action of the telescopic rod assembly 210.

[0048] Furthermore, refer to Figure 1 , Figure 2 As shown, the telescopic rod assembly 210 can only horizontally adjust the distance between the detection device 300 and the roll 500. However, when the outer diameter of the roll 500 to be detected changes, simply adjusting the distance horizontally between the detection device 300 and the roll 500 may not ensure ideal contact between the probe of the detection device 300 and the surface of the roll 500. For example, when the outer diameter of the roll 500 decreases, simply adjusting the distance horizontally between the detection device 300 and the roll 500 may result in the probe of the detection device 300 having difficulty contacting the surface of the roll 500. To avoid the above problems, the telescopic rod assembly 210 of this application is hinged to the first support 220, and a telescopic structure 400 is provided to drive the first support 220 to rotate around the hinge point with the telescopic rod assembly 210. The two ends of the telescopic structure 400 are respectively connected to the telescopic rod assembly 210 and the first support 220. The telescopic structure 400 can be a pneumatic telescopic rod, a hydraulic telescopic rod, or other similar equipment. (Refer to...) Figure 2 As shown, the first bracket 220 is hinged to the end of the movable rod 212. The telescopic structure 400 drives the first bracket 220 to rotate around the hinge point with the movable rod 212, thereby driving the second bracket 230 and the detection device 300 to rotate synchronously, thus ensuring that the probe of the detection device 300 can make ideal contact with the surface of the rolls 500 of each outer diameter.

[0049] In an embodiment of this utility model, the first bracket 220 includes a first mounting plate 221 and a second mounting plate 222, the first mounting plate 221 being perpendicular to the second mounting plate 222; the first mounting plate 221 is hinged to the telescopic rod assembly 210, and the length extension direction of the first mounting plate 221 intersects the length extension direction of the telescopic rod assembly 210. Specifically, refer to... Figure 2 As shown, the first mounting plate 221 is hinged to the movable rod 212; the first mounting plate 221 and the second mounting plate 222 can lower the installation position of the second bracket 230, thereby lowering the detection device 300 to a position corresponding to the roll 500, so that the detection device 300 can contact the outer surface of the roll 500.

[0050] In the embodiments of this utility model, reference is made to Figure 1 , Figure 2 As shown, the second bracket 230 includes a mounting groove 233, and a limiting plate 234 is provided above the mounting groove 233. A locking bolt 235 is installed on the limiting plate 234. The detection device 300 is installed in the mounting groove 233. The locking bolt 235 passes through the limiting plate 234 to abut against the detection device 300, so as to fix the position of the detection device 300 and prevent the detection device 300 from moving relative to the mounting groove 233, which would affect the detection accuracy of the surface roughness of the roll 500.

[0051] To further improve the stability of the testing equipment 300, in this embodiment, the first mounting plate 221 of the first bracket 220 is perpendicular to the second mounting plate 222 to form a first bent portion; the second bracket 230 includes a third mounting plate 231 and a fourth mounting plate 232, the third mounting plate 231 and the fourth mounting plate 232 being perpendicular to form a second bent portion; the first bent portion and the second bent portion are fitted together, and the fourth mounting plate 232 rests on the second mounting plate 222 and is connected by fasteners. Specifically, refer to... Figure 1 , Figure 2 As shown, the fasteners connecting the fourth mounting plate 232 and the second mounting plate 222 can be bolts or similar structures. The fourth mounting plate 232 rests on the second mounting plate 222, allowing the second mounting plate 222 to support the second bracket 230 via the fourth mounting plate 232, reducing the probability of fastener loosening and improving the stability of the second bracket 230. The first bent portion and the second bent portion are in contact, allowing the first bracket 220 and the second bracket 230 to support and restrain each other, further improving the stability of the bracket assembly 200.

[0052] In an embodiment of this utility model, the sleeve assembly 100 is equipped with a stop block 131, which is movable relative to the sleeve assembly 100 in the radial direction. The stop block 131 is used to abut against the roll 500 passing through the sleeve assembly 100 to reduce the rotational speed of the roll 500. Specifically, refer to... Figure 1 , Figure 2As shown, the end of the first sleeve 110 is equipped with a support lug 130, which is bolted to a bolt. A stop block 131 is installed on the bolt. By rotating the bolt, the stop block 131 can be driven to move closer to or away from the roll 500 that passes through the sleeve assembly 100. The stop block 131 can be made of nylon block or other structures. It is preferable to provide two supports 130, which are symmetrically arranged to avoid radial displacement of the roll 500 and affecting the detection accuracy of the surface roughness of the roll 500.

[0053] In the embodiments of this utility model, reference is made to Figure 1 , Figure 2 As shown, the sleeve assembly 100 in this embodiment also includes a second sleeve 120, which is sleeved on the outer periphery of the first sleeve 110 and can slide along the first sleeve 110. Specifically, the mounting base 122 is disposed on the second sleeve 120, and the second sleeve 120 slides axially along the first sleeve 110, which can drive the support assembly 200 and the detection device 300 to slide synchronously, thereby changing the detection position of the detection device 300 on the roll 500 in the axial direction. Through multi-position detection, the detection accuracy of the surface roughness of the roll 500 is further improved.

[0054] Furthermore, the first sleeve 110 is provided with a radially protruding first structural member 113, and the second sleeve 120 is provided with a second structural member 121. The first structural member 113 is connected to one of the second structural members 121 to fix the relative positions of the first sleeve 110 and the second sleeve 120. (Refer to...) Figure 1 , Figure 2 As shown, the first structural component 113 and the second structural component 121 can be connected by studs. For example, the first structural component 113 protrudes radially from the outer surface of the first sleeve 110 and has a through hole for bolts to pass through. The second structural component 121 is a threaded hole and is located on the end face of the second sleeve 120. The first structural component 113 and the second structural component 121 are connected by studs, and nuts or clamping structures are installed on the studs to fix the relative positions of the first structural component 113 and the second structural component 121. The first structural component 113 and the second structural component 121 can also be connected by telescopic cylinders or telescopic hydraulic cylinders depending on the actual situation. After the first structural component 113 and the second structural component 121 are connected, the second sleeve 120 cannot continue to slide along the axial direction of the first sleeve 110, thereby improving the accuracy of the surface roughness detection results of the roll 500.

[0055] It is conceivable that the second sleeve 120 in this embodiment can be configured to be unable to rotate relative to the first sleeve 110 around its own axis, or it can be configured to rotate relative to the first sleeve 110 around its own axis. The appropriate solution can be selected according to the actual situation, and no limitation is made in this embodiment. If the second sleeve 120 is configured to be able to rotate relative to the first sleeve 110 around its own axis, it is preferable that after the first structural member 113 and the second structural member 121 are connected, the second sleeve 120 can be restricted from sliding along the axial direction of the first sleeve 110 and rotating relative to the first sleeve 110 at the same time. For example, taking the first structural member 113 as mentioned above as radially protruding from the outer surface of the first sleeve 110 and the second structural member 121 as a threaded hole, multiple threaded holes can be provided around the circumference, and the first structural member 113 is connected to one of the second structural members 121 by bolts. Alternatively, multiple first structural members 113 can be provided around the circumference, and the second structural member 121 is connected to one of the first structural members 113 by bolts. After the first sleeve 110 and the second sleeve 120 are connected by the first structural component 113 and the second structural component 121, it does not affect the rotation of the first sleeve 110 relative to the roll 500.
