[0019] Example 1

[0020] Please see Figures 1 to 2 The present invention provides the following technical solution: a journal flatness thickness detection device, which is suitable for the detection of journal flatness thickness.

[0021] Specifically, such as Figure 1 and Figure 2 As shown, a journal flatness thickness detection device includes a dial indicator 1, which includes a dial indicator body 11 and a detection probe 12; it also includes a pressing component 3 and a positioning component 4; the top end of the detection probe 12 extends out of the dial indicator body 11 and is connected to the outer wall of the dial indicator body 11 through the pressing component 3; the bottom end of the detection probe 12 extends out of the dial indicator body 11 and enters the positioning component 4.

[0022] The specific implementation process is as follows: the positioning component 4 is fixed on the flat area of ​​the journal being measured to ensure that the detection probe 12 can be accurately aligned with the measurement position; further, a certain pressing force is applied to the detection probe 12 by the pressing component 3 to make it in close contact with the flat area of ​​the journal being measured; at this time, the pointer of the dial indicator will start to rotate and display the measurement value; after the pointer stabilizes, the measurement value on the dial indicator 1 is read and recorded for subsequent analysis; by using the pressing component 3 and the positioning component 4, the stability of the detection probe 12 during the measurement process is ensured, and measurement errors caused by shaking or offset are avoided; by replacing different positioning components 4 and adjusting the parameters of the pressing component 3, the detection device can adapt to the measurement needs of the flat thickness of journals with different shapes, sizes and materials, thereby expanding the application range of the detection device.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, the positioning component 4 includes an inverted U-shaped groove 41 and a telescopic member 42; one end of the detection probe 12 is vertically inserted into the inverted U-shaped groove 41; the telescopic member 42 is disposed within the inverted U-shaped groove 41 and extends horizontally towards the detection probe 12. The positioning component 4 also includes an operating handle 43; the operating handle 43 is disposed outside the inverted U-shaped groove 41 near the end of the telescopic member 42 and extends towards the pressing component 3.

[0024] In this embodiment, the pressing component 3 can be adjusted by holding the operating handle 43, which saves time and effort.

[0025] In this embodiment, the telescopic component 42 includes a memory spring post and a pressing head 421; the positioning component 4 also includes a limiting base 44 opposite to the detection probe 12; the pressing head 421 is connected to the inverted U-shaped groove 41 via the memory spring post; the pressing head 421 extends towards the limiting base 44. The pressing head 421 can press against the side of the limiting journal. Furthermore, a limiting baffle 5 is provided at one end of the pressing head 421 near the detection probe 12. This presses and fixes the top of the journal, further improving the stability during detection and ensuring the accuracy of the detection; wherein, the limiting baffle 5 is vertically connected to the pressing head 421 via a telescopic spring.

[0026] Specifically, such as Figure 1 and Figure 2As shown, the pressing assembly 3 includes a pressing handle 31 and a hinge 32; the pressing handle 31 has a sliding opening at one end near the watch body 11 for the detection probe 12 to pass through; the pressing handle 31 extends towards the operating handle 43 at the other end away from the watch body 11; the middle part of the pressing handle 31 is connected to the watch body 11 through the hinge 32.

[0027] In this embodiment, the hinge 32 includes a slanted rod connected to the top outer wall of the watch body 11 and a hinge buckle hinged to the slanted rod; by pressing one end of the pressing handle 31, the sliding mouth of the other end of the pressing handle 31 moves, thereby realizing the lifting and lowering adjustment of the detection probe 12; wherein, the end of the pressing handle 31 with the sliding mouth is arc-shaped, so as to quickly generate a height difference to adjust the position of the detection probe 12.
