[0026] This utility model provides a driving mechanism for a roughness tester, including a measuring instrument 101 and a mounting assembly. The mounting assembly includes a fixed plate 102, a movable lead screw 103, a movable slider 104, a connecting plate 105, a rotating component, and a reinforcing plate 106. The rotating component includes a fixed frame 107, a rotating rack 108, a movable gear 109, a drive shaft 110, a guide block 111, a mounting base 113, and a telescopic component 114. The fixed frame 107 has a sliding groove 112, and the guide block 111 has an extension portion 115. The aforementioned solution solves the problem that the second electric push rod in the driving unit of existing roughness testers has a limited range, making it unable to perform longer-length detections on longer objects and thus lacking practicality. It is understood that the aforementioned solution can also be used to solve problems related to circumferential rotation.

[0027] In this specific embodiment, the movable lead screw 103 is rotatably connected to the fixed plate 102 and located on one side of the fixed plate 102. The movable slider 104 is connected to the movable lead screw 103. One end of the connecting plate 105 is fixedly connected to the movable slider 104, and the other end of the connecting plate 105 is connected to the rotating component. The rotating component is connected to the measuring instrument 101. The fixed plate 102 is used for support. The movable lead screw 103 is rotatably arranged on both sides of the fixed plate 102. The two movable lead screws 103 are arranged opposite each other and are driven to rotate together by synchronous motors. The movable sliders 104 are respectively connected to the two movable lead screws 103. The two movable sliders 104 correspond to each other. The connecting plate 105 is fixed to the outer wall of the two movable sliders 104 respectively. The rotating component is fixed between the two connecting plates 105. The rotating component drives the measuring instrument 101 to move in a circle. The measuring instrument 101 is used for roughness detection.

[0028] One end of the reinforcing plate 106 is fixedly connected to the movable slider 104, and the other end of the reinforcing plate 106 is fixedly connected to the rotating component. Multiple reinforcing plates 106 are used, each fixed to both the movable slider 104 and the rotating component, thereby enhancing the stability of the rotating component's installation.

[0029] Secondly, the fixed frame 107 is fixedly connected to the connecting plate 105 and the reinforcing plate 106 respectively. The rotating rack 108 is fixedly connected to the fixed frame 107 and is located inside the fixed frame 107. The moving gear 109 meshes with the rotating rack 108 and is located inside the rotating rack 108. The drive shaft 110 is fixedly connected to the moving gear 109. The fixed frame 107 is fixed between the two connecting plates 105, and the rotating rack 108 is fixed inside. The rotating rack 108 meshes with the moving gear 109 inside. The drive shaft 110 passes through the moving gear 109, and one end is connected to a micro motor. The motor drives the drive shaft 110 to rotate, thereby driving the moving gear 109 to rotate. The moving gear 109 moves along the rotating rack 108.

[0030] Simultaneously, the guide block 111 is rotatably connected to the drive shaft 110 and slidably connected to the fixed frame 107. The fixed frame 107 has a sliding groove 112, which is located on the inner side of the fixed frame 107 and cooperates with the guide block 111. The guide block 111 has an extension 115, which is located on the side of the guide block 111 away from the drive shaft 110 and extends into the interior of the fixed frame 107. Guide blocks 111 are respectively provided on both sides of the drive shaft 110. The guide blocks 111 allow the drive shaft 110 to rotate. The bottom of the guide block 111 extends into the slide groove 112 of the fixed frame 107 and moves along the slide groove 112 to guide the movement. The extension 115 extends into the inner side of the fixed frame 107 to limit the guide block 111 and prevent it from moving out of the fixed frame 107, thereby ensuring the stable movement of the moving gear 109 on the rotating rack 108.

[0031] Additionally, the mounting base 113 is fixedly connected to the guide block 111 and is located on the side of the guide block 111 away from the drive shaft 110. The telescopic member 114 is connected to the mounting base 113, and the output end of the telescopic member 114 is connected to the measuring instrument 101. The mounting base 113 moves along the fixed frame 107 and the rotating rack 108 following the guide block 111. The telescopic member 114 is an electric telescopic rod, and its output end is connected to the measuring instrument 101, driving the measuring instrument 101 to extend and retract, approaching the workpiece for roughness detection.

[0032] Using the drive mechanism of a roughness tester according to this embodiment, the workpiece is passed through the rotating rack 108 and then fixed from both ends. At this time, the moving lead screw 103 is started to rotate, driving the moving slider 104 to move. Then, the connecting plate 105 and the reinforcing plate 106 drive the fixed frame 107 to move along the length direction of the workpiece. During the movement, the drive shaft 110 is driven to rotate, driving the moving gear 109 to rotate. Then, the moving gear 109 moves along the rotating rack 108, driving the mounting base 113 and the telescopic member 114 to move along the rotating rack 108, driving the measuring instrument 101 to move. During the movement, the guide block 111 moves along the slide groove 112, and the telescopic member 114 drives the measuring instrument 101 to extend and retract, adjusting its distance from the workpiece to perform roughness detection. Thus, it is possible to perform longer-length detection on longer objects, improving practicality.
