[0019] The technical solution of the present invention has the following advantages:

[0020] 1. The present invention provides a universal tooling for testing the plug-in and pull-out force and sealing force of a sealing strip. The upper module is used to connect to a testing machine, and the lower module is fixedly arranged. A testing space is formed between the upper module and the lower module. A testing component and a sealing strip clamp are respectively connected to the upper module and the lower module. The upper module is moved close to the lower module so that the sealing strip fixed by the sealing strip clamp and the testing component are close to and in contact with each other to complete the testing of the sealing strip. During the testing process, the plug-in and pull-out force and the sealing force of the sealing strip need to be tested respectively, and the tooling and clamps used for testing the plug-in and pull-out force and testing the sealing force are different. The operator only needs to replace the testing component and the sealing strip clamp, and install different testing components and sealing strip clamps on the upper module and the lower module to complete the testing of the plug-in and pull-out force and the sealing force, thereby avoiding the need to design and replace all the tooling during the testing process.

[0021] 2. The universal tooling for testing the plugging and unplugging force and sealing force of sealing strips provided by the present invention comprises a testing component including a plugging plate for testing the plugging and unplugging force of sealing strips. When testing the plugging and unplugging force of sealing strips, the plugging plate is installed in the first slide groove on the lower module and fixed by a pin, and the sealing strip clamp is installed in the second slide groove on the upper module so that the opening of the sealing strip faces the plugging plate. The upper module is moved so that the sealing strip is inserted into the plugging plate during the process of pressing the upper module against the lower module to simulate the insertion force of the sealing strip. After the insertion force test is completed, the upper module is moved away from the lower module so that the sealing strip is separated from the plugging plate to simulate the unplugging force of the sealing strip, thereby completing the plugging and unplugging force test of the sealing strip.

The upper module is moved. During the process of pressing the upper module against the lower module, the pressure block squeezes the water retaining lip of the sealing strip to simulate the sealing force of the sealing strip, thereby completing the test of the sealing force of the sealing strip.

[0023] 4. The universal tooling provided by the present invention for testing the plugging and unplugging force and sealing force of sealing strips has a pressing surface on the pressing block, which can be an aluminum alloy plate surface or a glass plate surface, and can simulate more usage environments of the sealing strip.

[0024] 5. The universal tooling for testing the plug-in and pull-out force and sealing force of the sealing strip provided by the present invention also includes a positioning block. Before testing the sealing strip, the upper module needs to be positioned, and the extension strip of the positioning block is placed in the positioning groove on the lower module, so that the positioning block and the lower module are fitted together, and the upper module is moved so that the upper module abuts against the upper surface of the positioning block. The testing machine records the position of the upper module at this time, and the positioning of the upper module is completed. After positioning, the positioning block is stored in the temporary storage grooves on both sides of the lower module for easy use and storage by the operator.

[0033] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] This embodiment provides a specific implementation of a universal tool for testing the plugging and unplugging force and sealing force of a sealing strip, such as Figure 1 As shown, it includes an upper module 1 and a lower module 2, the upper module 1 is connected to a test machine, the test machine has a sensor and a display screen, the lower module 2 is fixedly arranged on a working plane, the upper module 1 and the lower module 2 are arranged relative to each other in the vertical direction, and a test space 3 is formed between the upper module 1 and the lower module 2, the test component and the sealing strip fixture are respectively connected to the upper module 1 and the lower module 2, and the upper module 1 is controlled by the test machine to move downward, so that the sealing strip fixed by the sealing strip fixture and the test component are close to each other and in contact, during the contact process, the force detected by the sensor forms a force curve on the display screen, and the test of the sealing strip is completed. During the test process, the plug-in force and the sealing force of the sealing strip need to be tested separately, and the tooling fixtures used for testing the plug-in force and the sealing force are different. The operator only needs to replace the test component and the sealing strip fixture, so that different test components and sealing strip fixtures are installed on the upper module 1 and the lower module 2, and the plug-in force and the sealing force of the sealing strip can be completed. The test can avoid the need to design and replace all the tooling during the test process.

[0038] In this embodiment, a positioning block 4 is provided, and the height of the positioning block is set to 10 mm. Before testing the sealing strip, the upper module 1 needs to be positioned so that the operator can determine the test plane of the upper module 1. In the process of programming the test machine, the same test plane is used for programming, that is, when testing the plug-in and pull-out force and sealing force of the sealing strip, only two sets of programs need to be written to complete the plug-in and pull-out force and sealing force tests of different sealing strips. When finding the test plane, the extension strip of the positioning block 4 is placed in the positioning groove on the lower module 2, so that the positioning block 4 is fitted with the lower module 2, and the upper module 1 is moved so that the upper module 1 is in contact with the upper surface of the positioning block 4. The test machine records the position of the upper module 1 at this time, and completes the positioning of the upper module 1. After positioning, the positioning block 4 is stored in the temporary receiving groove 6 on both sides of the lower module 2. There is an adsorption device in the temporary receiving groove 6, and the adsorption device can be a magnet, which is convenient for the operator to use and store.

[0039] like Figure 2 and Figure 3 As shown, when testing the plugging and unplugging force of the sealing strip, the test component is the plugging plate 14, and the sealing strip fixture is the plugging and unplugging force test fixture 13. The plugging plate 14 is installed in the first slide groove 5 on the lower module 2 and fixed by the pin 7. The sealing strip is installed in the plugging and unplugging force test fixture 13. The plugging and unplugging force test fixture 13 is installed in the second slide groove 8 on the upper module 1 and fixed by the pin 7 so that the opening of the sealing strip faces the plugging plate 14. At this time, the control test machine starts the shelling function, that is, removes the gravity influence of the upper module 1, the sealing strip, and the sealing strip fixture; the control test machine moves The upper module 1 is pressed down until the lower surface of the upper module 1 moves to the test plane position. At this time, the sealing strip is inserted into the plug board 14, and the sensor transmits the detected data to the background. After the background processing, the curve of the insertion force is displayed on the display screen; after the insertion force test is completed, the upper module 1 is moved away from the lower module 2, so that the sealing strip is separated from the plug board 14. During this process, the sensor transmits the detected data to the background. After the background processing, the curve of the pull-out force is displayed on the display screen, simulating the pull-out force of the sealing strip, thereby completing the test of the plug-in and pull-out force of the sealing strip.

[0040] Specifically, the lower module 2 includes a base 12 and a sliding seat 11. The base 12 is provided with grooves on both sides. The bottom of the sliding seat 11 is fixedly connected to a shaft body. Rollers are rotatably installed at both ends of the shaft body. The rollers are rollingly installed in the grooves to achieve the sliding installation of the sliding seat 11 and the base 12. When testing the plugging and unplugging force of the sealing strip, loosen the pin 7 installed on the base 12 so that the sliding seat 11 can slide on the base 12. The force generated when the sealing strip is inserted into the plug plate 14 can make the plug plate 14 drive the sliding seat 11 to slide back and forth a certain distance, which can simulate the situation when the manual installation of the sealing strip encounters resistance and the operator shakes the sealing strip to make it easier to install the sealing strip on the workpiece, thereby obtaining a more realistic plugging and unplugging force of the sealing strip.

[0041] like Figure 2 and Figure 4As shown, when testing the sealing force of the sealing strip, the test component is a pressing block 15, and the sealing strip fixture is a sealing force test fixture 10. The pressing block 15 is installed in the second slide groove 8 on the upper module 1 and fixed by the pin 7. The sealing force test fixture 10 is installed in the third slide groove 9 on the lower module 2 and fixed by the pin 7. At the same time, the water retaining lip of the sealing strip is facing the pressing block 15. At this time, the control test machine starts the shelling function, that is, removes the gravity influence of the upper module 1 and the pressing block 15. The control test machine moves the upper module 1, so that the upper module 1 is pressed down until the lower surface of the upper module 1 moves to a position 2 mm below the test plane. In this process, the pressing block 15 squeezes the water retaining lip of the sealing strip to simulate the sealing force of the sealing strip. The sensor transmits the detected data to the background. After the background processing, the initial sealing force curve is displayed on the display screen, and the values ​​of the lower surface of the upper module 1 on the test plane and at the test plane plus or minus 2 mm are taken to complete the test of the sealing force of the sealing strip.

[0042] Specifically, the pressing block 15 has a pressing surface, which may be an aluminum alloy plate surface or a glass plate surface, and can simulate more usage environments of the sealing strip.

[0043] Working principle:

[0044] Before the test, take out the positioning block 4 from the temporary accommodating groove 6 and place it on the upper surface of the lower module 2. Control the testing machine to move the upper module 1 until the lower surface of the upper module 1 abuts against the upper surface of the positioning block 4. At this time, the testing machine records the lower surface of the lower module 2 as the test plane. After determining the test plane, control the testing machine to move the upper module 1, take out the positioning block 4 and place it in the temporary accommodating groove 6, install the plug-in force test fixture 13 to the upper module 1, install the plug-in plate 14 to the lower module 2, and control the testing machine to shell. After shelling, the upper module 1 is controlled by the testing machine to move downward until the lower surface of the upper module 1 moves to the test plane, and the test of the sealing strip insertion force is completed. Then, the upper module 1 is controlled by the testing machine to move upward until the sealing strip is completely separated from the plug-in plate 14, and the test of the sealing strip extraction force is completed. Replace the sealing strip fixture and test components, install the pressing block 15 to the upper module 1, and install the sealing force test fixture 10 to the lower module 2, so that the water retaining lip of the sealing strip faces upward, and control the testing machine to shell. After shelling, the upper module 1 is controlled by the test machine to move downward until the lower surface of the upper module 1 moves to 2 mm below the test plane, and the values ​​at the test plane and the position of plus or minus 2 mm on the test plane are taken to complete the test of the sealing force of the sealing strip. This universal tooling only needs to replace the sealing strip fixture and test components according to the specifications of the sealing strip, and they are all slidingly installed for easy disassembly and assembly. The module design of the external contour saves costs, and the same test plane is used to reduce the number of programming times.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
