[0033] Multiple gasket placement frames 2 can be provided, mainly depending on actual technical requirements. The stopper 2-2 is installed at the lower end of the gasket placement sleeve 2-1 and fixed. The gasket placement sleeve 2-1 after the above installation is fixed to the frame 1. The gasket thickness nameplate 2-3 is installed on the frame 1. Its function is mainly to facilitate manual labor to find the gasket placement sleeve 2-1 of gaskets 2-5 of different thicknesses more quickly.

Manual labor can quickly select the corresponding gasket 2-5. The gasket 2-5 is placed in the gasket placement sleeve 2-1 below the corresponding gasket thickness nameplate 2-3 according to the material thickness. The upper end of the gasket placement sleeve 2-1 adopts a V-shaped opening form, which is mainly convenient for manual placement of gaskets.

[0034] The housing 4-1 is mounted on the frame 1, the cylinder 4-2 is fixed to the upper end of the cylinder mounting seat 4-3, the cylinder joint 4-4 is installed at the front end of the piston rod of the cylinder 4-2, and the fixing part 4-5 and the pressing block 4-6 are installed at the same time. The fixing part 4-5 is first connected to the cylinder joint 4-4, and then the pressing block 4-6 is fastened to the fixing part 4-5, and then the support block 4-7 is installed to the lower end of the cylinder mounting seat 4-3, one on each side, first fix the pressing block anti-rotation shaft 4-18 to the lower end of the cylinder mounting seat 4-3, and then install the reference block 4-10 to the lower end of the support block 4-7, and at the same time The block anti-rotation shaft 4-18 is clamped, wherein the block anti-rotation shaft 4-18 is mainly used to prevent the block 4-6 from rotating through the piston rod of the cylinder 4-2, and the support shaft 4-9 is installed to the lower end of the reference block 4-10, and three are installed respectively, and then the bushing 4-17 is inserted into the positioning hole on the reference block 4-10, and three are installed respectively, and at the same time, the probe mounting seat 4-8 is installed to the lower end of the support shaft 4-9, and then the probe mounting sleeve 4-12 is installed into the mounting hole of the probe mounting seat 4-8, and three are installed respectively, and at the same time, the probe 4-11 is inserted into the probe mounting sleeve 4-12, and The probe installation sleeve 4-12 is locked, and 3 are installed respectively; first install the contact head 4-16 into the bushing 4-17, pass the guide shaft 4-13 through the hole at the bottom of the probe installation sleeve 4-12, and then install the spring sleeve 4-14 into the guide shaft 4-13, and finally insert the spring 4-15 into the guide shaft 4-13, and then pass the guide shaft through the hole at the lower end of the contact head 4-16 and lock it with the lower end of the reference block 4-10, and install the left and right sides according to the above steps.

Its working principle is as follows: the gasket 2-5 is placed on the upper end surface of the reference block 4-10, and after positioning through the anti-rotation shaft 4-18 of the pressure block, the cylinder 4-2 drives the pressure block 4-6 to press down, and the lower end surface of the pressure block 4-6 contacts with the upper end surface of the contact head 4-16 and moves the contact head 4-16 downward, and the head of the probe 4-11 moves downward through the downward movement of the contact head 4-16 until the gasket 2-5 is pressed tightly, and the probe 4-11 can measure the corresponding value. Conversely, the pressure block 4-6 is driven to move up to the corresponding position after being compressed by the spring 4-15. Then the probe mounting seat 4-8 is installed inside the housing 4-1.
