Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] Please see Figures 1-4 This utility model discloses a gasket thickness measuring instrument, including a testing platform 1 and a fixed support 2 fixedly connected to the top surface of the testing platform 1, and also includes a placement platform assembly 3, a measuring assembly 4, and a motorized lifting assembly 5, wherein:

[0022] The testing station 1 is equipped with a display screen 11 at one end, and a power switch 12 and a calibration button 13 are provided on one side of the display screen 11.

[0023] Please refer to the appendix. Figure 2 The placement stage assembly 3 includes a raised placement stage 31 with a placement groove 32. The measuring assembly 4 includes a pressure sensor 41 with a sensor housing 411. One end of the sensor housing 411 is fitted with a measuring head 412 and is slidably engaged. Specifically, during measurement, the measuring head 412 is compressed and generates displacement, which is converted into pressure detected by the pressure sensor 41. The greater the displacement, the greater the pressure.

[0024] Please refer to the appendix. Figure 4 A calibration plate 42 is welded to the outer side of the sensor housing 411. Calibration rods 43 are symmetrically arranged on the bottom surfaces of both ends of the calibration plate 42. Displacement rods 44 are symmetrically arranged between the calibration rods 43. The displacement rods 44 pass through the calibration plate 42 and slide together. The bottom end of the displacement rods 44 is fixedly connected to the measuring disk 45. The top surface of the measuring disk 45 is provided with a docking post 46. Specifically, the calibration rods 43 can prevent the measuring head 412 from shrinking due to external downward pressure during measurement, so as to achieve accurate measurement of the pad 6.

[0025] Pressure sensor 41 is electrically connected to test stage 1. A gasket 6 is placed in the placement slot 32. The bottom surface of measuring plate 45 abuts against the gasket 6. The docking post 46 abuts against the measuring head 412. The calibration rod 43 is located directly above the placement stage 31.

[0026] In this embodiment, during measurement, the measuring disc 45 presses down on the pad 6 until the calibration rod 43 abuts against the placement platform 31. The pad 6 gives the measuring disc 45 a reaction force, which drives the docking post 46 to squeeze the measuring head 412, causing the measuring head 412 to contract and generate displacement. This causes the pressure sensor 41 to detect the pressure signal and convert the pressure signal into an electrical signal, which is then transmitted to the data processing module in the detection platform 1. After processing, the thickness value of the pad is displayed on the screen. Example 2

[0027] Based on the above embodiment 1, please refer to the appendix. Figure 2 as well as Figure 3 The placement slot 32 has a groove 33 in the center. The groove 33 is a circular groove. Specifically, the groove 33 can facilitate the removal of the gasket 6 from the groove 33.

[0028] The fixed bracket 2 includes a fixed plate 22 located at the top of the fixed shaft 21, and a bearing 23 is fixed to the top surface of the fixed plate 22 by screws.

[0029] The motorized lifting assembly 5 includes a measuring frame 51, with a fixed shaft 21 passing through one end of the measuring frame 51 and slidingly engaged.

[0030] The measuring frame 51 is penetrated by a spiral shaft 52 and rotates in a spiral manner. A rotating handle 53 is installed at the top of the spiral shaft 52. The spiral shaft 52 is locked to the bearing 23 through a bearing bushing. The bearing 23 can reduce the friction when the spiral shaft 52 rotates and improve the detection efficiency.

[0031] One end of the measuring frame 51 is provided with a threaded knob 54, and the pressure sensor 41 passes through the measuring frame 51 and is locked.

[0032] In this embodiment, rotating the handle 53 drives the spiral shaft 52 to rotate using the bearing 23. The spiral shaft 52 interacts with the measuring frame 51, generating relative displacement using the spiral force, which in turn drives the measuring frame 51 to slide downward on the fixed shaft 21. The measuring frame 51 drives the pressure sensor 41 to slide downward until the calibration rod 43 on the pressure sensor 41 abuts against the placement platform 31, thereby measuring the thickness of the pad 6.

[0033] The working principle and usage process of this utility model are as follows: First, rotate the threaded knob 54. The interaction between the threaded knob 54 and the thread at one end of the measuring frame 51 causes it to deform, thereby locking the pressure sensor 41 that passes through the measuring frame 51.

[0034] Then, crank the handle 53. The handle 53 drives the spiral shaft 52 to rotate using the bearing 23. The spiral shaft 52 interacts with the measuring frame 51, and the relative displacement is generated by the spiral force. This causes the measuring frame 51 to slide downward on the fixed shaft 21. The measuring frame 51 drives the pressure sensor 41 to slide downward until the calibration rod 43 on the pressure sensor 41 abuts against the placement platform 31. At this time, the measuring disk 45 abuts against the placement groove 32, and the docking post 46 abuts against the measuring head 412. At this time, the display screen 11 shows the reading when no pad is placed. Press the calibration button to perform zero calibration.

[0035] Then, rotate the handle 53 in the opposite direction to lift the measuring plate 45 and place the pad 6 into the placement slot 32. Repeat the calibration operation to make the measuring plate 45 press down on the pad 6 until the calibration rod 43 abuts against the placement stage 31. The pad 6 gives the measuring plate 45 a reaction force, which drives the docking column 46 to squeeze the measuring head 412, causing the measuring head 412 to contract and generate displacement. This causes the pressure sensor 41 to detect the pressure signal and convert the pressure signal into an electrical signal, which is transmitted to the data processing module in the detection stage 1. After processing, the thickness value of the pad is displayed on the screen. The operation is simple, quick, and highly accurate.
