It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0031] At present, due to the special cup-shaped zinc pot sinking roller sleeve and thin wall thickness, the data obtained by directly measuring with a hardness tester is not accurate, and it may even be impossible to measure the hardness. There is currently no high-precision and high-convenience hardness testing method in the industry.

[0032] Based on this, an embodiment of the present disclosure provides a device for detecting the hardness of the sleeve of a zinc pot sinking roller. The installation portion of the present disclosure includes a working section and an installation section, wherein the working section is used to fix the sleeve. After the sleeve is installed on the working end, the interior of the sleeve is filled, and the hardness of the sleeve can be measured, avoiding the existing problem that the hardness cannot be measured; and the detection portion includes a displacement mechanism and a detection mechanism, and the displacement mechanism is used to drive the detection mechanism to move in the extension direction of the working section, which can make the position of the hardness tester and the sleeve surface more variable, provide more detection samples, and make the measured hardness more accurate.

[0033] The device for detecting the hardness of the zinc pot sinking roller sleeve is described in detail by means of a specific embodiment below:

[0034] Reference Figures 1 to 4 As shown, the present disclosure provides a device for detecting the hardness of a zinc pot sinking roller sleeve, including a detection part 1, a mounting part 2 and a base 3, wherein the mounting part 2 is arranged on the base 3, and the mounting part 2 includes a working section 21 and a mounting section 23, wherein the working section 21 is used to fix the sleeve 10; the detection part 1 includes a displacement mechanism 11 and a detection mechanism 12, wherein the displacement mechanism 11 is arranged on the mounting section 23, and wherein the displacement mechanism 11 is used to drive the detection mechanism 12 to move in the extension direction of the working section 21; the detection mechanism 12 includes a first fixing member 121 and a hardness meter mounting position 122, wherein the first fixing member 121 is used to fix the hardness meter 20 at the position of the hardness meter mounting position 122.

[0035] The mounting portion 2 disclosed in the present invention includes a working section 21 and a mounting section 23, wherein the working section 21 is used to fix the sleeve 10. After the sleeve 10 is installed in the working section 21, the interior of the sleeve 10 is filled, and the hardness of the sleeve 10 can be accurately measured, avoiding the existing problem that the hardness cannot be measured; and the detection portion 1 includes a displacement mechanism 11 and a detection mechanism 12, and the displacement mechanism 11 is used to drive the detection mechanism 12 to move in the extension direction of the working section 21, which can make the position of the hardness tester 20 and the surface of the sleeve 10 more variable, provide more detection samples, and make the hardness measurement more accurate.

[0036] Specifically, the mounting portion 2 of the present invention can be selected as an integrally formed long strip column horizontally mounted on the base 3, and the mounting portion 2 is divided into a working section 21 and a mounting section 23 in the center, and the working section 23 can be sized according to the specific model of the sleeve to obtain the best filling effect. The base 3 serves as the supporting structure of the entire equipment, and a supporting structure composed of a support frame, a supporting column or a plurality of legs can be selected. Furthermore, the base 3 and the mounting portion 2 can be connected in a detachable manner to facilitate overall storage and maintenance. The displacement mechanism 11 of the present invention can be driven by a drive member such as a lead screw stepper motor, a telescopic air cylinder, and a telescopic oil cylinder, wherein the detection mechanism 12 is provided with a hardness meter installation position 122. It should be noted that the hardness meter 20 should be perpendicular to the surface of the sleeve 10 after being assembled at the hardness meter installation position 122 to ensure accurate test results. The first fixing member 121 of the present invention can fix the hardness meter 20 by means of clamping, screwing, etc. The present invention specifically provides a bolt hole at the hardness meter installation position 122, and the first fixing member 121 is provided as a bolt. The first fixing member 121 is fixed to the hardness meter 20 through the bolt hole.

[0037] In some embodiments, the displacement mechanism 11 includes a slide 111, a slider 112 and a connecting plate 113. The slide 111 is arranged on the mounting section 23. One end of the slider 112 is slidably matched with the slide 111, and the other end is connected to the connecting plate 113. The detection mechanism 12 is arranged at one end of the connecting plate 113 close to the working section 21 to realize the convenience of operation of the device. Furthermore, the driving source of the slider 112 can be a telescopic motor. When adjusting, the driving end of the telescopic motor pushes the slider 111 to move.

[0038] In some embodiments, the base 3 includes a support plate 31 and a connecting frame 32 . The connecting frame 32 is disposed on the support plate 31 , and the connecting frame 32 is used to support the mounting portion 2 .

[0039] In this embodiment, the base 3 supports the plate 31 and the connecting frame 32 to ensure the stability of the base 3. Further, the connecting frame 32 is provided with a lifting mechanism, which is used to adjust the height of the connecting frame 32 to adapt to various use environment requirements.

[0040] In some embodiments, the working section 21 is configured as a cylinder, and the diameter of the working section 21 is adjustable. The mounting section 23 is configured as a rectangular body, and the displacement mechanism 11 is disposed on a side of the mounting section 23 opposite to the base 3 .

[0041] In this embodiment, the cylindrical working section 21 can better fit the interior of the sleeve 10, so that the interior is filled more fully to obtain more accurate detection data. As the section 21 is set as a rectangular body, its plane is more stable for the assembly of the displacement mechanism. The diameter of the working section 21 can be adjusted, for example, an inflatable device is set on the surface or inside of the working section 21 so that its shape can be changed, or the working section 21 is divided into a plurality of sub-sections as a whole, and each sub-section is connected by a telescopic rod.

[0042] In some embodiments, a limiting plate 22 is disposed on one side of the working section 21 close to the installation section 23 .

[0043] In this embodiment, a limiting plate 22 is provided on one side of the working section 21 close to the mounting section 23. The limiting plate 22 can better limit the sleeve 10, so that the sleeve 10 slides into the range of the mounting section 23 during operation. Furthermore, the limiting plate 22 can be configured as an annular plate body uniformly distributed in the axial direction of the working section 21 to improve the limiting effect.

[0044] In some embodiments, a second fixing member is further included, and the limiting plate 22 is slidably connected to the working section 21 , and the second fixing member is used to fix the position of the limiting plate 22 in the extending direction of the working section 21 .

[0045] In this embodiment, the limit plate 22 is slidably connected to the working section 21, which can better fit the sleeves 10 of various lengths. After the sleeve 10 is assembled to the working section 21, the sliding limit plate 22 abuts against the end of the sleeve 10 to limit the position, thereby reducing the detection error rate. Among them, the limit plate 22 can be set as an annular plate sleeve on the working section 21, and its internal shape is adapted to the actual shape of the working section 21. The second fixing member can be fixed by screw connection, clamping, etc.

[0046] In some embodiments, a rotating mechanism is further included, and the working section 21 is connected to the mounting section 23 via the rotating mechanism, and the rotating mechanism is used to drive the mounting section 23 to rotate along the circumferential direction of the working section 21 .

[0047] In this embodiment, the rotating mechanism is intended to drive the detection end of the hardness tester 20 to rotate along the circumference of the sleeve, providing detection samples at more positions. The rotating mechanism can be set as a rotating structure such as a rotating shaft or a rotating table.

[0048] In some embodiments, the sleeve 10 and the working section 21 are clearance-matched, and the clearance is set to 0.02 mm to 0.04 mm. In this embodiment, the clearance is set to 0.02 mm to 0.04 mm. When the clearance is less than 0.02 mm, the sleeve 10 is difficult to assemble; when the clearance is greater than 0.04 mm, the clearance between the inside of the sleeve 10 and the working section 21 is too large, and the insufficient filling degree affects the measurement.
