Description

Technical Field

[0001] This utility model belongs to the field of testing tooling technology, specifically relating to testing tooling for the production and processing of high-speed steel rolls. Background Technology

[0002] High-speed steel rolls are essential tools in the steel metallurgical industry for hot and cold rolling processes, widely used in the processing of metals such as steel, aluminum, and copper. Due to the high temperature, high pressure, and high-speed operating environment they endure, their performance and quality requirements are extremely high. The production process of high-speed steel rolls involves multiple stages, one of the most critical being the quality inspection of the rolls, ensuring that they meet the required mechanical properties, wear resistance, and surface quality during processing.

[0003] In existing technologies, when inspecting internal defects in steel rolls, the steel rolls are generally placed on a fixed support, and workers use handheld detectors to inspect them. By slowly moving the detectors along the outer wall of the steel rolls, different locations are inspected, thereby improving the accuracy of the inspection.

[0004] During the testing process, the detector needs to be in close contact with the outer wall of the steel roll to ensure effective transmission of ultrasonic signals and accurate test results. The detector may shake during manual handheld movement, causing gaps between the detector and the outer wall of the steel roll. This can lead to leakage of ultrasonic signals and distortion of the propagation path, resulting in inaccurate test data. Utility Model Content

[0005] To overcome the problem that existing steel roll inspection fixtures may cause inaccurate test data due to the shaking of the manually held detector during movement, which may lead to gaps between the detector and the outer wall of the steel roll, resulting in leakage of ultrasonic signals and distortion of the propagation path, a high-speed steel roll production and processing inspection fixture is proposed.

[0007] Preferably, the cleaning component includes a first connecting plate, with the first connecting plate fixed to both ends of the clamping block, a second connecting plate fixed to the lower end of the first connecting plate, and a cleaning block disposed at the lower end of the second connecting plate.

[0008] Preferably, the upper end of the cleaning block is fixed with a first buckle, and the left and right ends of the second connecting plate are provided with slots, and the first buckle is adapted to the slots.

[0009] Preferably, two support plates are fixedly connected to the upper end of the base plate, and two rollers are rotatably arranged between the two support plates. A first motor is fixedly connected to the left end of the support plate, and the rollers located on the front side are fixedly connected to the output end of the first motor.

[0010] Preferably, a fixing rod is fixedly connected to the inner side of the support plate, a first fixing ring is fixedly connected to the inner side of the fixing rod, a second fixing ring is rotatably provided at the upper end of the first fixing ring, and a fixing bolt is threadedly installed at the other end of the second fixing ring. The second fixing ring is fixedly connected to the first fixing ring through the fixing bolt.

[0011] Preferably, the adjustment assembly includes a damping rod, a damping rod fixed to the outside of the support plate, a support rod rotatably mounted on the outer wall of the damping rod, a guide rail fixed to the upper end of the support rod, a screw rotatably mounted on the inner wall of the guide rail, a slider threaded onto the outer wall of the screw, and a cylinder fixed to the lower end of the slider.

[0012] Preferably, a second motor is fixedly connected to the right end of the guide rail, and the screw is fixedly connected to the output end of the second motor.

The second buckle is adapted to the support rod.

[0013] The beneficial effects of this utility model are as follows: By starting the cylinder, the clamping block moves downward. Since the lower end face of the detector is lower than the lower end face of the pulley, the detector will first contact the outer wall of the steel roll body. At this time, the clamping block continues to move downward so that the outer wall of the pulley fits against the outer wall of the steel roll body. Under the action of the spring, the detector can be stably fitted against the outer wall of the steel roll body, avoiding gaps that would cause ultrasonic waves to diffuse outward. This solves the problem that when a manually held detector is moved, it may shake, causing gaps between the detector and the outer wall of the steel roll, which would lead to leakage of ultrasonic signals and distortion of the propagation path, resulting in inaccurate detection data.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-6 This utility model provides an embodiment of a high-speed steel roll production, processing, and inspection fixture, including a base plate 1; it also includes a cylinder 101 and a cleaning component; the cylinder 101 is mounted on the upper end of the base plate 1, and a clamping block 102 is fixedly connected to the output end of the cylinder 101. A first groove 103 is formed at the lower end of the clamping block 102, and a detector 104 is slidably mounted on the inner wall of the first groove 103. A spring 105 is fixedly connected between the detector 104 and the top of the inner wall of the first groove 103. The side of the clamping block 102 is arc-shaped, and two pulleys 106 are rotatably mounted at the lower edge of the clamping block 102. A steel roll body 107 is mounted at the lower end of the clamping block 102, and a cleaning component is mounted on the outer side of the clamping block 102. The cleaning component is activated by starting the cylinder. 101 drives the clamping block 102 to move downward. Since the lower end face of the detector 104 is lower than the lower end face of the pulley 106, the detector 104 will first contact the outer wall of the steel roll body 107. At this time, the clamping block 102 continues to move downward so that the outer wall of the pulley 106 fits against the outer wall of the steel roll body 107. Under the action of the spring 105, the detector 104 can be stably fitted against the outer wall of the steel roll body 107, avoiding gaps that would cause ultrasonic waves to diffuse outward. This solves the problem that the detector 104 may shake during manual handheld movement, causing gaps between the detector 104 and the outer wall of the steel roll, which would lead to leakage of ultrasonic signals and distortion of the propagation path, resulting in inaccurate detection data.

[0023] Please see Figures 1-4In this embodiment, the cleaning component includes a first connecting plate 201. The first connecting plate 201 is fixed to the left and right ends of the clamping block 102. A second connecting plate 202 is fixed to the lower end of the first connecting plate 201. A cleaning block 203 is provided at the lower end of the second connecting plate 202. A first buckle 204 is fixed to the upper end of the cleaning block 203. Slots 205 are provided at the left and right ends of the second connecting plate 202. The first buckle 204 is adapted to the slots 205. Since the cleaning block 203 and the detector 104 are on the same plane, the cleaning block 203 will clean the impurities on the surface of the steel roll body 107 during the movement of the clamping block 102, so as to avoid the impurities affecting the transmission of ultrasonic waves and causing inaccurate detection results. Two support plates 2 are fixed to the upper end of the base plate 1. Two rollers 3 are rotatably arranged between the two support plates 2. The left end of the support plate 2 is fixed to A first motor 4 is provided, and the front idler roller 3 is fixedly connected to the output end of the first motor 4. A fixing rod 5 is fixedly connected to the inner side of the support plate 2, and a first fixing ring 6 is fixedly connected to the inner side of the fixing rod 5. A second fixing ring 7 is rotatably set at the upper end of the first fixing ring 6, and a fixing bolt 8 is threadedly installed at the other end of the second fixing ring 7. The second fixing ring 7 is fixedly connected to the first fixing ring 6 through the fixing bolt 8. The steel roll body 107 is placed between the two idler rollers 3, and the rotating rod of the steel roll body 107 will be in contact with the inner wall of the idler roller 3. Then, the second fixing ring 7 is rotated to close with the first fixing ring 6. The fixing bolt 8 limits the steel roll body 107 to prevent shaking during the rotation of the steel roll body 107, which would affect the test results. The first motor 4 is started to drive the front idler roller 3 to rotate, which in turn drives the steel roll body 107 to rotate.

[0024] Please see Figures 1-6 In this embodiment, the adjustment assembly includes a damping rod 301. The damping rod 301 is fixedly connected to the outer side of the support plate 2. A support rod 302 is rotatably mounted on the outer wall of the damping rod 301. A guide rail 303 is fixedly connected to the upper end of the support rod 302. A screw 304 is rotatably mounted on the inner wall of the guide rail 303. A slider 305 is threaded onto the outer wall of the screw 304. A cylinder 101 is fixedly connected to the lower end of the slider 305. A second motor 306 is fixedly connected to the right end of the guide rail 303. The screw 304 is fixedly connected to the output end of the second motor 306. The second motor 306 is used to drive the screw 304 to rotate. A limiting plate 307 is fixed to the outer side of the support plate 2. The side of the limiting plate 307 is L-shaped. The outer wall of the support rod 302 fits against the inner wall of the limiting plate 307. A second buckle 308 is fixed to the inner wall of the limiting plate 307. The second buckle 308 is adapted to the support rod 302. By starting the second motor 306, the screw 304 is driven to rotate, so that the slider 305 drives the clamping block 102 to move along the outer wall of the screw 304. This allows the detector 104 to move and detect along the outer wall of the steel roll body 107. By detecting different positions, the accuracy of the detection data can be improved.

[0025] In use, the steel roll body 107 is first placed between two support rollers 3. The rotating rod of the steel roll body 107 will be in contact with the inner wall of the support roller 3. Then, the second fixing ring 7 is rotated to close with the first fixing ring 6. The steel roll body 107 is limited by the fixing bolt 8 to prevent shaking during the rotation of the steel roll body 107, which would affect the detection results. The first motor 4 is started to drive the front support roller 3 to rotate, which in turn drives the steel roll body 107 to rotate, so that the detector 104 can detect each position of the steel roll body 107.

[0026] Then, the support rod 302 is rotated to move the clamping block 102 above the steel roll body 107. Under the action of the second buckle 308, the support rod 302 is limited. Then, the cylinder 101 is started to drive the clamping block 102 to move downward. Since the lower end face of the detector 104 is lower than the lower end face of the pulley 106, the detector 104 will first contact the outer wall of the steel roll body 107. At this time, the clamping block 102 continues to move downward so that the outer wall of the pulley 106 is in contact with the outer wall of the steel roll body 107. Under the action of the spring 105, the detector 104 can be stably attached to the outer wall of the steel roll body 107, avoiding the problem of gaps causing ultrasonic waves to diffuse outward and affecting the detection results.

[0027] During testing, the second motor 306 is started to drive the screw 304 to rotate, causing the slider 305 to move the clamping block 102 along the outer wall of the screw 304. This allows the detector 104 to move and test along the outer wall of the steel roll body 107. By testing different positions, the accuracy of the test data can be improved. Since the cleaning block 203 and the detector 104 are on the same plane, the cleaning block 203 will clean the impurities on the surface of the steel roll body 107 during the movement of the clamping block 102, thus preventing impurities from affecting the transmission of ultrasonic waves and causing inaccurate test results.

[0028] Through the above steps, the cylinder 101 drives the clamping block 102 to move downward. Since the lower end face of the detector 104 is lower than the lower end face of the pulley 106, the detector 104 will first contact the outer wall of the steel roll body 107. At this time, the clamping block 102 continues to move downward so that the outer wall of the pulley 106 is in contact with the outer wall of the steel roll body 107. Under the action of the spring 105, the detector 104 can be stably attached to the outer wall of the steel roll body 107, avoiding gaps that would cause ultrasonic waves to diffuse outward. This solves the problem that the detector 104 may shake during manual handheld movement, causing gaps between the detector 104 and the outer wall of the steel roll, which would lead to leakage of ultrasonic signals and distortion of the propagation path, resulting in inaccurate detection data.
