[0029] Example 1
[0030] A cartridge bottom cover compression valve contact point depth measuring tool, such as Figure 1 , comprising a workbench 1, a sensor fixing seat 2, a positioning body 4, a displacement sensor 3, a ruler seat 5 and a detection probe 6.
[0031] The displacement sensor 3 comprises a sensor main body 33, a ruler body 32 and a display assembly 31.

[0033] The displacement sensor 3 further comprises a display assembly 31, which is a digital display screen and is connected to the equipment outside through a cable, and can be installed at a position convenient for the employee to read.
[0034] The ruler body 32 is arranged in the positioning body 4, the ruler seat 5 is connected with the ruler body 32, the ruler seat 5 is provided with a groove for installing the ruler body 32, and after the ruler seat 5 is clamped into the upper limit position of the positioning body 4, the detection surface of the ruler seat 5 will be just at the detection point, such as Figure 3 , wherein A is the detection point, and the positioning body 4 is a cylinder in the embodiment, the positioning body 4 is provided with guide groove bodies 41 symmetrically arranged on both sides, and the ruler seat 5 moves along the guide groove bodies 41.
[0035] The positioning body 4 is provided with an elastic assembly 7, preferably a spring, which is used for supporting and resetting the ruler seat 5, so that the employee can automatically rebound when taking out the product after completing the detection by sleeving and pressing down, thereby achieving the purpose of simplifying the detection operation.
[0036] The detection probe 6 is installed on the positioning body 4, and the detection probe 6 is a valve body profiling structure, which is used to simulate the cooperation of the valve body and the cartridge assembly. Specifically, the detection probe 6 includes a compression valve structure simulation block 61 and a cartridge positioning ring 62, both of which are detachably arranged. By replacing the compression valve structure simulation block 61 of various valve body structures and the cartridge positioning ring 62 suitable for various pipe diameters, the measurement of different types of products can be realized.
[0037] The detection probe 6 is arranged and combined through various standard blocks, so that the gauge can simulate the cooperation of various valve bodies and cartridge assemblies. After the product is welded, the situation can be effectively detected. The displacement sensor 3 with a cooperation accuracy of 0.01 mm can satisfy the purpose of improving the detection accuracy.
[0038] Preferably, the compression valve structure simulation block 61 and the cartridge positioning ring 62 are both provided with a groove body cooperating with the ruler seat 5, respectively groove one 511 and groove two 621, for the ruler seat 5 to pass through, so that the ruler seat 5 can satisfy the measurement of various products with different pipe diameters, and the applicability is improved.
[0039] The positioning body 4 is provided with a positioning structure 42, and the compression valve structure simulation block 61 and the cartridge positioning ring 62 are both provided with a cooperating structure, respectively a cooperating protrusion 612 and a cooperating hole 622.

[0040] The detection surface of the ruler seat 5 is flush with the cooperation of the detection probe 6 and the cartridge assembly. When detecting, the detection probe 6 is in contact with the cartridge assembly, the ruler seat 5 moves, and the displacement sensor 3 measures the moving distance to complete the measurement of the compression valve contact point depth on the cartridge bottom cover.
[0041] The measurement principle of the scheme is as follows: Figure 6As shown, the present scheme adopts a displacement sensor instead of a depth ruler as a measuring tool. The special measuring head can be separated from the measuring ruler body after modification, so that the ruler bridge can be modified, and the zero point position can be re-planned with the external product positioning measuring head. After improvement, the staff only needs to push the ruler body to the limit and press the zero reset button. The operation is simple and does not need to be repeated. The original product needs to be zeroed every time the product is replaced, but this design only needs to be zeroed once. After zeroing, the staff only needs to put the product into the measuring tool to the bottom, and observe the digital display on the screen to determine whether the depth is qualified. Unlike the original mobile measuring tool, the present application is equipped on a small workbench and can be placed beside the workstation. The staff can hold the completed product with one hand and measure it. The original design requires one hand to take the measuring tool and the other hand to hold the product for measurement. When the stroke is large, the operation is difficult. Therefore, the present application is simple and fast to operate, and has little effect on production efficiency.
[0042] Due to the simplified operation steps, the indirect measurement of the difference value is changed to the direct measurement of the depth, the accuracy of the measurement result is directly improved, and the error caused by personnel operation is effectively reduced. Due to the simple and unified operation action, the subsequent robot automatic line can be used for work.
[0043] The design that the detection measuring head 6 is independently fixed on the pedestal makes the quick mold changing design simple and easy to implement. The detection measuring head 6 directly simulates the contact of the bottom valve with the bottom cover. After the product is put into the bottom, the measuring tool reading can directly reflect the actual situation after the bottom cover is welded. Abnormalities can be directly reflected on the reading, effectively improving the measurement accuracy, reducing the influence of human factors, improving the production efficiency and product consistency, and facilitating standardized production management.
[0044] The present scheme can reduce the measurement difficulty: the valve body design and the multi-standard block replacement design of the detection measuring head 6 make the measuring tool can adapt to various liquid cylinder assemblies. At the same time, the actual contact point is simulated as a detection point. The cooperation of the ruler seat 5 and the positioning body 4 makes the ruler seat 5 move to the limit position and zero, and the contact point coincides. Such design greatly reduces the detection difficulty.
[0045] Due to the above zeroing method, the staff does not need to perform zeroing operation during production, reducing the frequency requirement of zeroing operation. During normal production, the staff needs to pick up the product pipe and put it into the measuring tool to the bottom with the pipe downward, then visually observe the depth number displayed on the digital display screen, and finally take out the product. Simple and standardized operation makes the present application can be mass-produced and used. The operator only needs to be guided simply, compared with the original detection which can only be performed by the inspection personnel who have received relevant training. The present application reduces the difficulty of liquid cylinder bottom cover detection.
[0046] The existing measuring method needs to measure with a depth ruler and calculate the actual depth according to the angle in the drawing, relies on the staff to measure and calculate, and obtains analog data in a calculating mode, and errors and mistakes are easily generated. The application directly measures the depth value from the contact point to the pipe end face through the probe capable of simulating the contact of the valve body, and has a pipe diameter positioning structure, so that the errors generated due to the operation problems of the staff are reduced. The digital display sensor is used for detection, the reading is performed by the machine, and the numerical value is the actual measured value, without any calculation and reading operation of the staff, so that the errors are greatly reduced, and the accuracy requirement of the detection is met.
[0047] It should be understood by those skilled in the art that the above description and the embodiments of the application shown in the drawings are only taken as examples and do not limit the application. The purpose of the application has been completely and effectively achieved. The function and structural principle of the application have been shown and described in the embodiments, and the embodiments of the application can have any deformation and modification without departing from the principle.
