DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 to Figure 5 , which is the first embodiment of the utility model, and this embodiment provides a metal surface roughness measuring device, which includes a main body component 100 and a rotating component 200, which can rotate the needle without turning over the entire instrument. The operator does not need to turn over the heavy instrument with effort, but only needs to press simply to rotate the needle, which greatly reduces the operating burden.

[0030] The main component 100 includes a detector 101, a control board 102 and a measuring needle 103. The control board 102 is fixed to one side of the detector 101. The measuring needle 103 is plugged into the top of the detector 101. The measuring needle 103 and the detector 101 are movably connected.

[0031] The detector 101 is responsible for receiving and processing the information about the metal surface collected by the measuring needle 103, and converting the physical quantity obtained by the measuring needle 103 into a roughness parameter that can be quantified and analyzed. The control board 102 is used to control the various operations and functions of the detector 101. The measuring needle 103 directly contacts the metal surface and senses the changes in its microscopic morphology. When the measuring needle 103 moves on the metal surface, the displacement change of its needle tip reflects the ups and downs of the surface.

[0032] The rotating assembly 200 is disposed on the detector 101 , and includes a rotating member 201 and a measuring member 202 . The rotating member 201 is disposed at the bottom of the measuring needle 103 , and the measuring member 202 is sleeved on the outer side of the measuring needle 103 .

[0033] When testing metal, the measuring needle 103 can be rotated once by the setting of the rotating member 201, and one rotation is completed after four rotations. The measuring needle 103 rotates four times to complete one rotation, and the metal surface can be tested from multiple directions and angles to obtain more comprehensive and representative roughness data. It avoids omissions and deviations that may be caused by single-direction detection. Multiple small-angle rotation measurements can average possible local errors, make the measurement results closer to the true value, and improve the accuracy and reliability of the measurement. When the rotating member 201 drives the measuring needle 103 to rotate four times, it can drive the measuring member 202 to move once, so that the measuring needle 103 can be recorded to rotate once. In this way, the measuring needle 103 can be counted by reciprocating, so that the number of rotations of the measuring needle can be accurately recorded, avoiding the errors that may be caused by manual counting and improving the accuracy of counting.

The movement of the driving bar 201c can squeeze the inclined surface of the driving groove X, so that the rotating rod 201b can rotate once.

[0040] Specifically, the rotating member 201 further includes a moving sleeve 201d and a spring 201e. The moving sleeve 201d is sleeved on the outside of the rotating rod 201b.

[0044] Specifically, the measuring member 202 includes a rotating disk 202 a movably connected to the top of the detector 101 .

[0045] When the measuring needle 103 rotates one circle, it can drive the rotating disk 202a to rotate once. By rotating the rotating disk 202a once, the number of rotations of the measuring needle 103 can be counted.

[0046] Specifically, the measuring member 202 further includes a scale frame 202b and an indicator block 202c. The scale frame 202b is fixed to the top of the detector 101, and the indicator block 202c is fixed to one side of the rotating disk 202a.

[0047] Corresponding numbers are set on the scale frame 202b. By rotating the rotating disk 202a once, the indicator block 202c can be driven to rotate. Before the indicator block 202c rotates to the designated number on the scale frame 202b, the staff can intuitively see the recorded number of laps.

[0048] Example 3

[0049] Reference Figure 3 to Figure 5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0050] Specifically, the measuring member 202 further includes a driving block 202d and a driving frame 202e. The driving frame 202e is fixed to the top of the rotating disk 202a, and the driving block 202d is disposed on the top of the rotating disk 202a.

[0051] There are four driving frames 202e, all fixed on the top of the rotating disk 202a. When the measuring needle 103 rotates one circle, it can drive the driving block 202d to rotate one circle. The rotation of the driving block 202d will squeeze the driving frame 202e to make it move, and the movement of the driving frame 202e can drive the rotating disk 202a to rotate.

The rotation of the driving rod 202f can drive the driving block 202d to rotate and squeeze the driving frame 202e to move the driving frame 202e.

[0054] Specifically, the measuring member 202 further includes a gear 202h and a gear ring 202i. The gear 202h is fixed to the top of the rotating block 202g, and the gear ring 202i is arranged on one side of the gear 202h. The gear ring 202i is meshed with the gear 202h.

[0055] The gear ring 202i is sleeved on the outer side of the measuring needle 103.

When the driving bar 201c is reset, the driving slot X can guide the driving bar 201c to enter the inclined surface of the driving slot X. The driving slot X on the inclined surface can be squeezed by the movement of the driving bar 201c, so that the rotating rod 201b can be rotated once. The rotation of the rotating rod 201b can drive the support column 201a to rotate. The rotation of the support column 201a can drive the measuring needle 103 to rotate.
