[0024] like Figure 1-Figure 4 As shown, the present embodiment provides a surface smoothness detection device, comprising a base plate 1 and a workbench 2 located on the top of the base plate 1, a motor 7 is installed on the top of the base plate 1, a rectangular slide rod 6 is vertically installed on the output end of the motor 7, a support rod 3 is vertically slidably provided on the top of the rectangular slide rod 6, a rectangular slide hole 5 is provided at the bottom of the support rod 3, the rectangular slide rod 6 is located inside the rectangular slide hole 5, a lifting mechanism is provided on the outer side of the support rod 3, the top of the support rod 3 extends to the top of the workbench 2, a through hole is provided on the support rod 3 for the workbench 2 to pass through, a three-jaw chuck 4 is fixed on the top of the support rod 3, a micrometer 8 is installed at one end of the top of the workbench 2, and the detection end of the micrometer 8 faces the top of the three-jaw chuck 4, a translation mechanism is provided at the bottom of the micrometer 8, and a cleaning mechanism 21 is provided at the other end of the top of the base plate 1.

[0025] The overall working principle is as follows: during the inspection, the thrust rod ball seat is placed on the top of the three-jaw chuck 4, and then the three-jaw chuck 4 is used to locate the position. Then the translation mechanism is used to control the micrometer 8 to move toward the position of the thrust rod ball seat, and fit on the surface of the thrust rod ball seat. The micrometer 8 has a certain value displayed, and then the motor 7 is started to control the thrust rod ball seat on the three-jaw chuck 4 to rotate. The micrometer 8 detects the surface of the thrust rod ball seat. The smoothness of the surface of the thrust rod ball seat is determined by the change of the value on the micrometer 8. In addition, in the process of controlling the rotation of the thrust rod ball seat, the lifting mechanism is used to drive the support rod 3 to perform an upward adjustment, and the detection surface position of the thrust rod ball seat is automatically changed to ensure the accuracy of the inspection.

[0026] In this embodiment, the lifting mechanism includes a horizontal plate 9, a vertical rod 10, a cylindrical rod 11, a rotating rod 12, a retaining ring 13, an inclined plate 14 and a through-hole 15. The horizontal plate 9 is horizontally rotatably installed on the outer side of the support rod 3. The vertical rod 10 is vertically fixed to the bottom of the workbench 2. The vertical rod 10 is slidably connected to the horizontal plate 9. A cylindrical rod 11 is fixed to one end of the horizontal plate 9. The rotating rod 12 is rotatably installed on the top of the bottom plate 1. The retaining ring 13 is evenly fixed on the top of the rotating rod 12. An inclined plate 14 is obliquely provided between the upper and lower sets of retaining rings 13. The retaining rings 13 below the inclined plate 14 are all provided with through-holes 15. The cylindrical rod 11 is inserted between the retaining rings 13, and a rotating component is provided at the bottom end of the rotating rod 12.

[0027] Local working principle: In the process of controlling the rotation of the thrust rod ball seat, the support rod 3 will also rotate at the same time. At this time, the rotation of the rotating rod 12 is controlled by the rotating assembly, and the cylindrical rod 11 slides between the two sets of retaining rings 13, and then passes through the inclined plate 14 and slides upward along the inclined plate 14 to enter another plane. At this time, the position of the support rod 3 and the thrust rod ball seat will also be raised to change the detection plane.

[0028] In this embodiment, the rotating assembly includes a main gear 16 and a driven gear 17. The main gear 16 is fixed to the bottom end of the rectangular slide rod 6, and the driven gear 17 is fixed to the rotating rod 12. The main gear 16 and the driven gear 17 are of the same size and mesh with each other.

[0029] Local working principle: Through the transmission control between the main gear 16 and the driven gear 17, the angular velocity of the support rod 3 and the rotating rod 12 is the same. After the thrust rod ball seat rotates one circle, the rotating rod 12 also completes one circle of rotation. Then the cylindrical rod 11 automatically enters another plane along the inclined plate 14, and the detection surface of the thrust rod ball seat also changes, ensuring the accuracy of the data during detection.

[0030] In this embodiment, the translation mechanism includes a slide rail 18, a slider 19 and a screw 20. The slide rail 18 is fixed on the top of the workbench 2 and along the length direction of the workbench 2. The slider 19 is slidably provided inside the slide rail 18. The top of the slider 19 is fixedly connected to the micrometer 8. A screw 20 is rotatably installed between the two ends of the slide rail 18, and the screw 20 and the slider 19 are threadedly connected.

[0031] Partial working principle: After the thrust rod ball seat is positioned, the screw rod 20 is rotated to control the slider 19 to slide inside the slide rail 18, and the movement of the slider 19 drives the micrometer 8 to move horizontally.

[0032] In this embodiment, an adjusting wheel is fixed to the end of the screw rod 20, and anti-slip grooves are provided on the outer side of the adjusting wheel.

[0033] Partial working principle: The use of the adjusting wheel at the end of the screw 20 makes the rotation of the screw 20 more labor-saving and convenient.

[0034] In this embodiment, the cleaning mechanism 21 includes a vertical plate 22, a cross bar 23, a brush plate 24 and a spring 25. The vertical plate 22 is vertically arranged on the top of the workbench 2, and a cross bar 23 is horizontally slidably provided on the vertical plate 22. A brush plate 24 is fixed to one end of the cross bar 23 close to the support rod 3. A spring 25 is provided between the brush plate 24 and the vertical plate 22, and the cross bar 23 passes through the inside of the spring 25.

[0035] Partial working principle: After the thrust rod ball seat is installed, the brush plate 24 is controlled by the elastic force of the spring 25 to fit on the surface of the thrust rod ball seat, and the thrust rod ball seat is automatically cleaned during its rotation.

[0036] In this embodiment, a pull ring is fixed to one end of the cross bar 23 away from the brush plate 24 , and the diameter of the pull ring is greater than the diameter of the sliding hole on the vertical plate 22 .

[0037] Partial working principle: During the disassembly and assembly of the thrust rod ball seat, the sliding of the cross bar 23 is conveniently controlled by using the pull ring, so as to facilitate the disassembly and assembly of the thrust rod ball seat.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
