DETAILED DESCRIPTION

[0020] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0021] As Figure 1As shown, the roughness detector of the embodiment comprises a base 1, a lower support platform 2 slidably mounted on the base 1 along the Y-axis, an upper support platform 3 slidably mounted on the lower support platform 2 along the X-axis, a workbench 4 fixedly mounted on the upper support platform 3, a clamp 5 provided on the workbench 4 for fixing a workpiece 100, a stand 6 vertically provided on one side of the base 1, a sliding table 7 movably mounted on the stand 6 along the Z-axis, and a laser 8 mounted on one side of the sliding table 7 facing the base 1, wherein the X-axis, the Y-axis and the Z-axis are perpendicular to each other. The roughness of the workpiece 100 is detected by the laser 8. During the detection, the laser 8 emits a laser beam to the measured surface of the workpiece 100, and the reflected light is received by the laser 8 to form intuitive data values through data processing. The workpiece 100 is fixed on the clamp 5 on the workbench 4. The Y-axis sliding assembly between the lower support platform 2 and the base 1 and the X-axis sliding assembly between the lower support platform 2 and the upper support platform 3 enable the workpiece 100 to move reciprocally along the Y-axis and the X-axis relative to the laser 8. Since the laser 8 is connected to the sliding table 7, the sliding table 7 can move along the Z-axis on the stand 6, so that the workpiece 100 can move reciprocally along the Z-axis relative to the laser 8. Therefore, the laser 8 can detect the roughness of complex workpieces 100, and the operation is simple, convenient and widely applicable.

In the case of relative rotation between the Z-direction lead screw 61 and the sliding table 7, a pushing force is generated along the axial direction between the Z-direction lead screw 61 and the sliding table 7, thereby driving the sliding table 7 to move along the Z-axis.

[0025] In the embodiment, a guide column 62 is further arranged on the stand 6 and penetrates the sliding table 7. In this structure, the guide column 62 guides and limits the movement of the sliding table 7.

[0026] In the embodiment, the slide table 7 is detachably mounted with a base 71 on the side of the base 1, and the laser 8 is mounted on the end of the base 71 and faces the worktable 4. In the structure, the slide table 7 and the laser 8 are connected through the base 71, so that the laser 8 is convenient to disassemble and replace.

[0027] In the embodiment, the base 1 is further provided with a second driver 13 and a third driver 14, the output end of the second driver 13 is connected with the Y-direction screw rod 12, and the output end of the third driver 14 is connected with the Z-direction screw rod 61.
