Description

Technical Field

[0001] The utility model relates to the technical field of roller laser cladding repair, in particular to a detection device for H13 hot working die steel roller laser cladding repair. Background Art

[0002] H13 hot working die steel rolls play a vital role in industrial production. Their performance directly affects product quality and production efficiency. However, as the use time increases, defects such as wear and cracks often appear on the roll surface, which not only reduces the service life of the roll, but may also have a serious impact on production. Therefore, it is particularly important to repair the roll in a timely and effective manner.

[0003] As an efficient and accurate repair method, laser cladding repair technology has been widely used in the repair of rolling mill rolls. The cladding material is melted by a laser beam and deposited on the surface of the rolling mill roll to fill and repair defects. However, during the laser cladding repair process, key factors such as the quality, thickness, and uniformity of the cladding layer directly affect the repair effect. Therefore, accurate detection and control of the repair process is crucial. Traditional detection methods often have problems such as low accuracy and complex operation, and it is difficult to meet the high-precision and high-efficiency requirements of laser cladding repair. With the development of science and technology, especially the continuous progress in laser technology, computer vision technology, sensor technology and other fields, it is possible to develop new detection devices.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A further improvement of the technical solution of the utility model is that the workbench structure includes a support plate, a slide groove is provided in the middle of the upper end of the support plate and extends through the upper end of the support plate to the lower part, and the outer surfaces of two sliders are slidably connected to the inner cavity of the slide groove.

[0008] The above technical solution is adopted, in which a slide groove 1 is opened on the upper end of a support plate 1, so that the moving trajectory of two sliders 1 can be limited. When the fixing member 1 and the fixing member 2 need to fix the roller, the center position of the roller can be determined more accurately due to the limiting effect of the slide groove 1 on the moving trajectory of the slider 1. This not only simplifies the operation process and reduces the skill requirements for the operator, but also greatly improves the accuracy and efficiency of positioning.

[0009] A further improvement of the technical solution of the utility model is that the horizontal moving structure includes two sliders 2, the opposite surfaces of the two sliders 2 are rotatably connected with a threaded rod, the opposite surfaces of the two sliders 2 are fixedly connected with a guide rod, one end of the threaded rod is fixedly connected with a motor 1, the side of the motor 1 close to the slider 2 is fixedly connected with the slider 2, the upper ends of the two sliders 2 are fixedly connected with a connecting plate, the upper end of the connecting plate is fixedly connected with the output end of the hydraulic cylinder, the outer surface of the threaded rod is threadedly connected with a connecting block, the middle part of the connecting block is slidably connected with the outer surface of the guide rod, and the lower end of the connecting block is fixedly connected with a sensor.

[0010] The above technical scheme is adopted, in which the threaded rod is driven to rotate by an output end of the motor, so that the threaded rod can be used to drive the connecting block and the sensor to move, so that the sensor can be moved horizontally, so as to fully detect the roller. Through the cooperation of the connecting plate and the hydraulic cylinder, the horizontal moving structure can be driven to rise and fall, and then the sensor can be moved vertically, so that the sensor can detect rollers of different sizes. The combination of the horizontal and vertical movement capabilities of the sensor provides great flexibility and adaptability for the device, so that it can not only ensure comprehensive detection of the roller surface, but also automatically adjust according to the actual size of the roller, thereby improving detection efficiency and accuracy.

[0014] The above-mentioned technical solution is adopted, in which the slider 2 is slidably connected by utilizing the inner cavities of the two slide grooves on the same side, thereby avoiding the use of complex fixing devices or limiting mechanisms, thereby simplifying the overall structure and reducing manufacturing costs; in addition, since the slider 2 is evenly and stably supported during the lifting process, the risk of wear and damage is effectively reduced, thereby extending the service life of the device.

[0015] A further improvement of the technical solution of the utility model is that the driving structure includes a shell, the lower end of the shell is fixedly connected to the upper end of the support plate, a gear is rotatably connected to the middle of the inner cavity of the shell, and both ends of the gear pass through the inner cavity of the shell and extend to the outer surface of the shell, a motor 2 is fixedly connected to one side of the outer surface of the shell, the output end of the motor 2 is fixedly connected to the gear, a rack 2 is meshedly connected to the upper part of the outer surface of the gear, the rack 2 is slidably connected to the upper part of the shell, and a rack 1 is meshedly connected to the lower part of the outer surface of the gear, and the rack 1 is slidably connected to the lower part of the shell.

[0016] The above technical solution is adopted, in which the gear is driven to rotate in the inner cavity of the shell through the output end of motor 2, thereby driving the gear to mesh with the adjacent rack 1 and rack 2, thereby driving the movement of rack 1 and rack 2.

[0018] The above technical solution is adopted. In this solution, during the movement of rack one and rack two, two sliders one can be driven to move together, so that the distance between fixing part one and fixing part two can be indirectly adjusted. This distance adjustment mechanism enables fixing part one and fixing part two to flexibly adapt to rollers of different sizes, whether it is a larger roller or a smaller roller, by meshing the adjacent rack one and rack two through the gears, driving rack one and rack two to move, thereby ensuring that fixing part one and fixing part two can fix the roller tightly and stably, thereby ensuring the accuracy and reliability of the detection process.

[0019] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
