[0044] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.
[0045] The embodiment relates to a test tool which is beneficial to the permanent deformation performance test of the lip on the window sealing strip 3.
[0046] In the overall structure, refer to Figure 1 and Figure 2As shown in the figure, the test tool of the embodiment is used for carrying out the test of the window sealing strip, and the test tool comprises a first tool 1 and a second tool 2 which is slidably arranged on the first tool 1. The second tool 2 is provided with a profiling guide groove 21 which is a profiling sealing strip mounting groove and is used for mounting the window sealing strip 3. The first tool 1 is provided with a profiling part 11 which is a profiling door glass and can be inserted into the window sealing strip 3 and can make the oppositely arranged lips of the window sealing strip 3 to be arranged on both sides of the profiling part 11.
[0047] At this time, as in the above structure, by arranging the first tool 1 and the second tool 2, and arranging the profiling part 11 which is a profiling door glass on the first tool 1 and arranging the profiling guide groove 21 which is a profiling sealing strip mounting groove on the second tool 2, the window sealing strip 3 is mounted in the profiling guide groove 21, the profiling part 11 is inserted into the window sealing strip 3, and the oppositely arranged lips of the window sealing strip 3 are arranged on both sides of the profiling part, so that the actual installation state of the window sealing strip 3 and the glass can be simulated, and thus the permanent deformation performance test of the oppositely arranged lips of the window sealing strip 3 can be carried out, and the accuracy and reliability of the test can be improved.
[0048] At the same time, by using the sliding cooperation of the second tool 2 and the first tool 1, on the one hand, the installation of the second tool 2 on the first tool 1 is facilitated, and the convenience of assembly between the first tool 1 and the second tool 2 can be improved, and on the other hand, different second tools 2 can be replaced to match the installation of window sealing strips 3 of different specifications and models, so that the permanent deformation performance test of the lips of window sealing strips 3 of different specifications and models can be carried out, and thus the versatility of the test tool can be improved.
[0049] Based on the overall structure as above, in detail, continuing to refer to Figures 1 to 2 As a preferred embodiment, the test tool of the embodiment comprises a first tool 1 and a second tool 2, the second tool 2 slides relative to the first tool 1, the second tool 2 is provided with a profiling guide groove 21 which is a profiling sealing strip mounting groove and is used for mounting the window sealing strip 3, and the first tool 1 is provided with a profiling part 11 which can be inserted into the window sealing strip 3.
[0050] In order to facilitate the sliding of the second tool 2 on the first tool 1, a guide structure is arranged between the first tool 1 and the second tool 2 in the embodiment, and the guide structure is used for guiding the sliding of the second tool 2 on the first tool 1. At this time, the arrangement of the guide structure makes the installation of the second tool 2 on the first tool 1 more relaxed and smoother.
[0051] In some feasible embodiments, referring to Figures 1 to 3 and combining with Figure 6As shown in the figure, the first tooling piece 1 of the embodiment comprises a bottom plate 101, a first vertical plate 102 and a second vertical plate 103 oppositely arranged on the bottom plate 101, and a horizontal plate 104 connected to the first vertical plate 102 and above the bottom plate 101.
[0052] The guiding structure comprises the bottom plate 101, the first vertical plate 102 and the second vertical plate 103 which form a "U"-shaped sliding groove 10, and the second tooling piece 2 is embedded in the sliding groove 10. At this time, the structure design of the sliding groove 10 formed by the bottom plate 101, the first vertical plate 102 and the second vertical plate 103 is beneficial to the processing and preparation of the first tooling piece 1, and the embedding of the second tooling piece 2 in the sliding groove 10 can better guide the sliding of the second tooling piece 2 on the first tooling piece 1, and can ensure the stability of the second tooling piece 2 during sliding, prevent the second tooling piece 2 from deviating or shaking, and further improve the convenience of the installation of the second tooling piece 2 and save the installation time of the second tooling piece 2.
[0053] The horizontal plate 104 arranged on the first vertical plate 102 enables the profiling piece 11 to be detachably connected to the horizontal plate 104. In this way, the arrangement of the horizontal plate 104 not only provides a mounting basis for the arrangement of the profiling piece 11 and ensures the reliability of the connection of the profiling piece 11 to the horizontal plate 104, but also facilitates the replacement of profiling pieces 11 of different thicknesses and increases the flexibility of the test tooling by virtue of the detachable connection between the profiling piece 11 and the horizontal plate 104.
[0054] In specific implementation, the bottom plate 101, the first vertical plate 102 and the second vertical plate 103, and the horizontal plate 104 of the first tooling piece 1 can be integrally formed, that is, the first tooling piece 1 is integrally formed, which is beneficial to ensuring the precision of the sliding groove 10 and the installation precision of the profiling piece 11. Of course, it can be understood that the bottom plate 101, the first vertical plate 102 and the second vertical plate 103, and the horizontal plate 104 can be assembled into an integral whole by welding, screwing or the like, which is beneficial to reducing the processing cost of each component.
[0055] It is worth noting that in the embodiment, the first tooling piece 1 and the second tooling piece 2 are preferably made of metal, which can increase the structural strength and corrosion resistance of the test tooling by virtue of the characteristics of the metal material. Moreover, in specific implementation, the first tooling piece 1 and the second tooling piece 2 can be made of chromium-plated steel plates, which can ensure the structural strength and also have good high-temperature resistance. Of course, the first tooling piece 1 and the second tooling piece 2 can also be made of electrophoretic steel plates, which can also ensure the structural strength and have good corrosion resistance.
[0056] The profiling piece 11 of the embodiment is used for profiling the vehicle window glass, and in the overall structure, the profiling piece 11 is in the form of a plate. The thickness of the vehicle window glass for different vehicle models is usually 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm. At this time, in order to match the different thicknesses of the vehicle window glass, and more realistically simulate the actual installation of the vehicle window glass and the vehicle window sealing strip 3, the thickness of the profiling piece 11 of the embodiment is also set to 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm. At this time, according to the test needs, the profiling piece 11 with the required thickness is selected and installed on the horizontal plate 104.
[0057] In addition, in the specific implementation, the profiling piece 11 of the embodiment can be detachably connected to the horizontal plate 104 by screwing, clamping and the like. Among them, as a feasible implementation manner, as shown in Figure 2 and Figure 3 , a threaded hole 1101 is arranged at the top end of the profiling piece 11, a through hole 1041 corresponding to the threaded hole 1101 is arranged on the horizontal plate 104, and the profiling piece 11 is screwed on the horizontal plate 104 by screwing or bolting in the threaded hole 1101 through the screw in the through hole 1041. At this time, the detachable connection by the screw facilitates the fixed installation of the profiling piece 11, and is also beneficial to the replacement of different profiling pieces 11.
[0058] As another feasible implementation manner, as shown in Figure 4 , a connecting plate 12 is arranged on the profiling piece 11, and the profiling piece 11 is detachably connected to the horizontal plate 104 through the connecting plate 12. At this time, a threaded hole 1101 can be arranged on the connecting plate 12. The arrangement of the connecting plate 12 on the profiling piece 11 can increase the connection area between the profiling piece 11 and the horizontal plate 104, thereby further improving the reliability of the connection of the profiling piece 11 on the horizontal plate 104.
[0059] On the basis of the setting of the sliding groove 10, as a further preferred implementation manner in the embodiment, as shown in Figure 4 and Figure 7 , the guide structure further includes a guide groove 1021 arranged on at least one of the bottom plate 101, the first vertical plate 102 and the second vertical plate 103, and a guide block 201 arranged on the second tooling piece 2. The guide groove 1021 and the guide block 201 correspond to each other, and the guide block 201 is embedded and slides in the corresponding guide groove 1021.
[0060] At this time, by using the embedded sliding fit between the guide block 201 and the corresponding guide groove 1021, the convenience of mounting the second tooling piece 2 on the first tooling piece 1 can be further improved. When the cross section of the guide block 201 and the guide groove 1021 forms a trapezoidal or wedge-shaped structure, compared with the structure of the ordinary sliding groove 10, it has the characteristics of self-centering and higher positioning accuracy, and can better limit the second tooling piece 2 in the height direction of the first tooling piece 1, preventing the second tooling piece 2 from being separated from the first tooling piece 1.
[0061] It should be noted that the guide groove 1021 can be provided only on the bottom plate 101, or only on the first vertical plate 102, or only on the second vertical plate 103. At this time, the guide block 201 is provided on the corresponding position of the second tooling piece 2. Of course, the guide groove 1021 can also be provided on any two of the bottom plate 101, the first vertical plate 102 and the second vertical plate 103. At this time, the guide block 201 is also provided on the corresponding position of the second tooling piece 2. In addition, the guide groove 1021 can also be provided on the bottom plate 101, the first vertical plate 102 and the second vertical plate 103. At this time, the guide block 201 is also provided on the corresponding position of the second tooling piece 2. It should be noted that the positions of the guide groove 1021 and the guide block 201 can be interchanged, and such a setting is also possible.
[0062] In this embodiment, the size of the second tooling piece 2 in the sliding direction is preferably between 3mm and 5mm, which can facilitate the placement under the projector to measure the distance, and also facilitate the improvement of the accuracy of the test results. In specific implementation, the size of the second tooling piece 2 in the sliding direction can be set to 3mm, 4mm or 5mm, etc. In addition, it should be noted that the size of the second tooling piece 2 in the sliding direction can also be set to other values greater than 5mm, which should ensure the accuracy of the distance test between the two lips.
[0063] As a preferred embodiment, in this embodiment, the first tooling piece 1 is provided with a anti-disengagement structure for preventing the second tooling piece 2 from disengaging from the first tooling piece 1 along the sliding direction of the second tooling piece 2. By setting the anti-disengagement structure, the second tooling piece 2 can be effectively prevented from disengaging from the first tooling piece 1 along the sliding direction of the second tooling piece 2, thereby better ensuring the relative position of the second tooling piece 2 on the first tooling piece 1.
[0064] Specifically, as a feasible implementation, in the embodiment, the second tooling member 2 is provided with anti-disengagement structures at both ends, each of which comprises a limiting baffle, and at least one of the limiting baffles is detachably connected to the first tooling member 1. In this way, by using the detachable limiting baffle, the second tooling member 2 can be inserted and mounted on the first tooling member 1 from one end of the sliding groove 10. After the second tooling member 2 is installed in place, the limiting baffles at both ends are respectively abutted against both ends of the second tooling member 2. In this way, by using the limiting baffles, the second tooling member 2 can be effectively prevented from disengaging from the first tooling member 1 along the sliding direction of the second tooling member 2.
[0065] It should be noted that the limiting baffles at both ends can be detachably connected to the first tooling member 1, or one of the limiting baffles can be detachably connected to the first tooling member 1, and the other limiting baffle can be fixedly connected to the first tooling member 1. In specific implementation, for example, as shown in Figure 5 , an insertion groove 100 is arranged on the first tooling member 1, and the limiting baffle can be inserted and connected in the insertion groove 100. In this way, on the premise of ensuring the relative position of the second tooling member 2 on the first tooling member 1, the installation and disassembly of the limiting baffle are facilitated, and the assembly time is shortened.
[0066] As another feasible implementation, in the embodiment, the second tooling member 2 is provided with anti-disengagement structures at both ends, at least one of which comprises a limiting baffle detachably connected to the first tooling member 1, and an elastic member 41 arranged on the limiting baffle, and the limiting baffle is abutted against the second tooling member 2 through the elastic member 41. At this time, the anti-disengagement structure adopts the structure form of the limiting baffle and the elastic member 41, which can compensate for the manufacturing tolerance and ensure the limiting stability on the one hand, and can also ensure the limiting stability of the second tooling member 2 with different sizes in the sliding direction through this structure on the other hand.
[0067] Referring to Figure 5 , in the embodiment, the anti-disengagement structures arranged at both ends of the second tooling member 2 comprise a limiting baffle detachably connected to the first tooling member 1, and another anti-disengagement structure comprises a limiting baffle fixedly connected to the first tooling member 1 and an elastic member 41 arranged on the limiting baffle. By adopting the anti-disengagement structure form of the combination of the limiting baffle and the elastic member 41, the manufacturing tolerance can be compensated for and the limiting stability can be ensured on the one hand, and the limiting stability of the second tooling member 2 with different sizes in the sliding direction can also be ensured through this structure on the other hand.
[0068] For the sake of distinguishing and better understanding the embodiment, the fixed limiting baffle is defined as the first baffle 4 and the detachable limiting baffle is defined as the second baffle 5. In the embodiment, the first baffle 4 and the second baffle 5 are respectively arranged at two ends of the first tooling piece 1. The first baffle 4 is fixed with an elastic member 41, which is preferably a spring. An insertion groove 100 is arranged at one end of the first tooling piece 1, and the second baffle 5 is inserted into the insertion groove 100.
[0069] In the specific use, the second tooling piece 2 is inserted into the sliding groove 10 through the end provided with the insertion groove 100, so that one end of the second tooling piece 2 is tightly pressed against the spring, and then the other end of the second tooling piece 2 is abutted against the second baffle 5 inserted into the insertion groove 100, so that the second tooling piece 2 is better limited on the first tooling piece 1 by the elastic member 41 arranged on the first baffle 4 and the second baffle 5. It is worth mentioning here that in order to make the elastic member 41 better abut against the second tooling piece 2, an abutting plate can also be fixedly arranged at the end of the second tooling piece 2 close to the elastic member 41, so that the elastic member 41 is tightly pressed against the abutting plate.
[0070] It can be understood that in addition to arranging the elastic member 41 on the first baffle 4, the elastic member 41 can also be arranged on the second baffle 5, or elastic members 41 are arranged on both the first baffle 4 and the second baffle 5. In addition to the detachable connection between the second baffle 5 and the first tooling piece 1, the first baffle 4 and the first tooling piece 1 can also be detachably connected, or the first baffle 4 and the second baffle 5 are both detachably connected with the first tooling piece 1.
[0071] In addition, in order to facilitate the movement and operation of the test tooling, the hand holding part 1022 is also arranged on the first tooling piece 1. The hand holding part 1022 can be arranged as a columnar handle or a U-shaped handle, so as to facilitate the hand holding of the test tooling.
[0072] In the specific use of the test tooling of the embodiment, the window sealing strip 3 is installed in the profiling guide groove 21 on the second tooling piece, and after installation, the distance T0 between the inner and outer lips of the window sealing strip 3 is measured under the projector. Then the second tooling piece 2 is slid into the sliding groove 10 from one end of the sliding groove 10, and the profiling member 11 is inserted into the window sealing strip 3 from one side of the window sealing strip 3, so that the two opposite lips of the window sealing strip 3 are arranged on the two sides of the profiling member 11, and then the profiling member 11 is fixed on the first tooling piece 1 by screws or bolts.
[0073] Then, the test tool assembled with the window sealing strip 3 is placed into a heat aging test box, the temperature of the test box is (80±2) DEG C, after 48h, the test tool is taken out, and the second tool part 2 is taken out after being placed at room temperature for 24h. After being placed for (30±3) min, then the distance T1 between the inner and outer lips of the window sealing strip 3 at the same position is measured under a projector. Then, the lip compression permanent deformation rate is calculated according to the following formula:
[0074]
[0075] In the formula:
[0076] T0 is the distance between the two lips before the test (if the two lips interfere in the design state, T0=0), and the unit is mm;
[0077] T1 is the distance between the two lips after the test, and the unit is mm;
[0078] T is the thickness of the profiled part, and the unit is mm;
[0079] The degree of the lip compression permanent deformation is measured by the difference between the distance between the two lips before and after the test and the interference amount of the window glass (i.e. the profiled part 11) and the two lips.
