Technical Field
[0001] The utility model belongs to the technical field of sealant specimens, and particularly relates to a preparation tool for a tensile-shear specimen of a sealant. Background Technique
[0002] At present, when testing the tensile-shear performance of a sealant, specimens need to be prepared. The specimens in the prior art usually include two rectangular base plates with the same width. The two base plates are bonded together by the sealant. Specifically, when preparing the specimens, first, the uncured sealant is coated on one of the base plates to form a sealant layer. The sealant layer has a certain length and the same width as the base plate, and one end of the sealant layer is flush with the base plate. Then, the two base plates are aligned according to the length of the sealant layer and manually pressed together until the thickness of the sealant layer is pressed to the designed value. In this way, after the sealant layer is cured, the specimen can be formed. Then, the specimen is stretched along the length direction of the specimen, and the tensile-shear strength and bonding performance of the sealant can be tested.
[0003] However, when using the above preparation method, when manually pressing the two base plates together, the pressing force may sometimes be too large or too small. For example, when the pressing force is too large, the thickness of the sealant layer in the specimen will be less than the designed value, and when the pressing force is too small, the thickness of the sealant layer in the specimen will be greater than the designed value. In this way, when preparing the specimen, the thickness of the sealant layer in the specimen will deviate from the designed value, which will ultimately affect the test results. Therefore, there are still drawbacks and deficiencies in the prior art. Summary of the Utility Model

Detailed implementation manners
[0029] To make the objectives, technical solutions and beneficial effects of the present utility model clearer, the following further describes the implementation manners of the present utility model in detail with reference to the drawings.
[0030] As Figures 1 to 9As shown in the figure, the present utility model provides a preparation tooling for a tensile shear specimen of sealant, which includes a first base plate 7 and a second base plate 11 both in rectangular shape. The first base plate 7 and the second base plate 11 have the same width, and a sealant layer 8 with the same width as the first base plate 7 is bonded on the first base plate 7. One end of the sealant layer 8 is flush with the first base plate 7. Specifically, the first base plate 7, the second base plate 11 and the sealant layer 8 can form a specimen in the prior art, and the materials of the first base plate 7 and the second base plate 11 may be different; it further includes a horizontally arranged bottom plate 4. A groove structure 41 is vertically opened on one side of the top surface of the bottom plate 4, and a horizontally arranged fixing plate 5 which is integrally structured with the bottom plate 4 is fixedly connected to the other side of the top surface of the bottom plate 4. A first groove 51 for placing the first base plate 7 is vertically opened on the top surface of the fixing plate 5. The first groove 51 horizontally penetrates through the fixing plate 5, and the bottom surface of the first groove 51 is flush with the top surface of the bottom plate 4. In addition, the distance between the two groove walls of the first groove 51 is adapted to the plate width of the first base plate 7. In this way, when the first base plate 7 is placed into the first groove 51, the width direction of the first base plate 7 can be limited; a vertically distributed guide rod 12 is installed on the bottom surface of the groove structure 41. A horizontally distributed positioning plate 2 is sleeved and slidably connected on the guide rod 12. An adjusting device 3 which is vertically distributed and can adjust the height position of the positioning plate 2 is installed between the positioning plate 2 and the bottom surface of the groove structure 41. Specifically, when the adjusting device 3 adjusts the height position of the positioning plate 2, the positioning plate 2 can slide along the guide rod 12; and a second groove 21 for placing the second base plate 11 is vertically opened on the top surface of the positioning plate 2. The second groove 21 horizontally penetrates through the positioning plate 2, and the second groove 21 is opposite to the first groove 51 in position. The groove depth of the second groove 21 is less than the thickness of the second base plate 11. In addition, the distance between the two groove walls of the second groove 21 is adapted to the plate width of the second base plate 11. In this way, when the second base plate 11 is placed into the second groove 21, the width direction of the second base plate 11 can be limited.
[0031] Specifically, during use, first, according to the thickness of the sealant layer 8 design value and the thickness of the first base plate 7, the height position of the positioning plate 2 is adjusted in place through the adjusting device 3. The specific setting method for the height position of the positioning plate 2 to be in place is as follows: Assume the thickness of the first base plate 7 is t1, and the thickness of the sealant layer 8 design value is t2. When adjusting the height position of the positioning plate 2 in place, the bottom surface of the second groove 21 should be higher than the bottom surface of the first groove 51, and the vertical distance between the bottom surface of the second groove 21 and the bottom surface of the first groove 51 is t3, where t3 = t1 + t2. In addition, a pressing plate 1 horizontally distributed is provided on the positioning plate 2. The pressing plate 1 is a plate-like structure with a certain thickness to ensure that the pressing plate 1 will not bend during use. The pressing plate 1 and the positioning plate 2 are connected by vertically distributed connecting bolts 6, and the side of the pressing plate 1 close to the fixing plate 5 is located outside the positioning plate 2. Specifically, multiple connecting bolts 6 can be provided. When the pressing plate 1 is connected to the positioning plate 2, the screw end of the connecting bolt 6 passes through the pressing plate 1 and is threadedly connected to the positioning plate 2, and the head of the connecting bolt 6 abuts against the pressing plate 1.
[0032] During use, after the height position of the positioning plate 2 is adjusted in place; the first base plate 7 coated with the sealant layer 8 is horizontally placed into the first groove 51. At this time, the sealant layer 8 faces upward; then the second base plate 11 is horizontally placed into the second groove 21, and according to the length of the sealant layer 8, the first base plate 7 and the second base plate 11 are aligned. Then the pressing plate 1 is installed, and the pressing plate 1 and the positioning plate 2 are connected by using the connecting bolts 6. Since the depth of the second groove 21 is less than the thickness of the second base plate 11, at this time, the pressing plate 1 can press the first base plate 7 and the second base plate 11. And because t3 = t1 + t2, compared with the manual pressing method in the prior art, this pressing method can ensure that the thickness of the sealant layer 8 in the specimen is consistent with the design value, and can make the thickness of the sealant layer 8 uniform to avoid affecting the test results; finally, after the sealant layer 8 is cured, the pressing plate 1 is removed, and the completed specimen can be taken out.
[0033] In addition, since the height position of the positioning plate 2 can be adjusted, when preparing specimens with different thicknesses of the sealant layer 8 and when preparing specimens with different thicknesses of the first base plate 7 and the second base plate 11, it can also meet the preparation of specimens, that is, it can meet the preparation of specimens with different design requirements, and has strong applicability.
[0034] Furthermore, for the convenience of aligning the first base plate 7 and the second base plate 11, during use, as Figure 8 shown, according to the length of the sealant layer 8, marking lines 9 are provided on the sides of both the first base plate 7 and the second base plate 11. In this way, during use, the marking lines 9 can be used to align the first base plate 7 and the second base plate 11; or as Figure 9As shown, according to the length of the sealant layer 8, a marking tape 10 is provided on the first substrate plate 7 coated with the sealant layer 8, so that when in use, the edge of the marking tape 10 can be used to align the first substrate plate 7 with the second substrate plate 11, thereby facilitating alignment between the first substrate plate 7 and the second substrate plate 11.
[0035] The specific setting method of the adjustment device 3 is as follows: Figures 1 to 5 and Figure 7 As shown, the adjusting device 3 is a micrometer, and the positioning plate 2 is sleeved and installed on the fixed sleeve 31 of the micrometer by means of threaded connection. Specifically, the adjusting device 3 is roughly the same as the structure and use method of the micrometer in the prior art, that is, the adjusting device 3 includes a fixed sleeve 31, a micrometer screw 32, a micrometer cylinder 33, an adjusting knob 34 and a fine adjustment knob 35, etc., and corresponding scale lines and scale values are marked at corresponding positions of the fixed sleeve 31 and the micrometer cylinder 33; when in use, the operator first holds the positioning plate 2, and then rotates the micrometer cylinder 33 by adjusting the knob 34, and makes the micrometer cylinder 33 moves on the fixed sleeve 31, and at the same time, the micrometer screw 32 can move synchronously, so that the distance between the end of the micrometer screw 32 and the bottom surface of the groove of the groove structure 41 can be adjusted, and then the positioning plate 2 is slid along the guide rod 12 until the end of the micrometer screw 32 is abutted against the bottom surface of the groove of the groove structure 41 to position the height position of the positioning plate 2, so that the height position of the positioning plate 2 can be adjusted into place; in addition, the scale values on the fixed sleeve 31 and the micrometer cylinder 33 can be used to accurately adjust the height position of the positioning plate 2, thereby ensuring the adjustment accuracy.
[0036] When adjusting the height of the positioning plate 2, the positioning plate 2 needs to slide vertically along the guide rod 12. In order to ensure the stability of the positioning plate 2 during the sliding process, Figure 1 , Figure 3 and Figure 4 As shown, there are two guide rods 12, and the two guide rods 12 are symmetrically distributed on both sides of the groove structure 41. The two sides of the positioning plate 2 are respectively mounted on the guide rods 12 and are slidably connected to the guide rods 12. The adjustment device 3 is located in the middle position of the positioning plate 2. In this way, when in use, the stability of the positioning plate 2 during the sliding process can be guaranteed.
[0037] Further, such as Figure 1 , Figures 3 to 7As shown, the horizontal cross-section of the groove structure 41 is rectangular and is arranged parallel to the fixed plate 5. Vertical guide grooves 42 are provided at the four corners of the groove wall of the groove structure 41. The top ends of the guide grooves 42 are flush with the top surface of the bottom plate 4. The shape of the positioning plate 2 is adapted to the groove structure 41, and guide blocks 22 are fixedly connected to the four corners of the positioning plate 2. The guide blocks 22 are respectively located in the guide grooves 42 and are slidably connected to the bottom plate 4 through the guide grooves 42. Specifically, when the positioning plate 2 slides vertically along the guide rod 12, the guide blocks 22 can slide along the guide grooves 42 respectively, thereby improving the stability of the positioning plate 2 during the sliding process.
[0038] Further, as Figure 1 、 Figures 3 to 5 and Figure 7 shown, vertical slideways 43 that are vertically distributed and opposite to the positions of the guide grooves 42 are provided on the bottom plate 4 outside each guide groove 42. Each slideway 43 is respectively communicated with the inside of the corresponding guide groove 42; a horizontally distributed locking bolt 14 is threadedly connected to each guide block 22. The screw rods of the locking bolts 14 respectively penetrate through the slideways 43, and the heads of the locking bolts 14 are located outside the bottom plate 4. Specifically, during use, when the positioning plate 2 slides vertically along the guide rod 12, the locking bolts 14 can slide along the slideways 43. After the height position of the positioning plate 2 is adjusted in place, by rotating the locking bolts 14, the heads of the locking bolts 14 can be made to abut against the bottom plate 4, so that the position of the positioning plate 2 can be fixed more firmly.
[0039] Further, the number of the guide rods 12 can also be set to one. Specifically, as Figure 7 shown, the guide rod 12 is located on one side of the groove structure 41, and the adjusting device 3 is located on the other side of the groove structure 41. In this way, when the positioning plate 2 slides vertically along the guide rod 12, under the action of the guide grooves 42 and the guide blocks 22, the stability of the positioning plate 2 during the sliding process can also be ensured.
[0040] Further, as Figure 1 、 Figures 3 to 7 shown, a linear bearing 13 is sleeved and slidably connected to the guide rod 12. The linear bearing 13 vertically penetrates through the positioning plate 2 and is connected to the positioning plate 2. Specifically, the linear bearing 13 is a circular flange linear bearing in the prior art; when the linear bearing 13 is connected to the positioning plate 2, the flange at the bottom of the linear bearing 13 is located inside the positioning plate 2 and is connected to the positioning plate 2 by bolts, and the top end of the linear bearing 13 penetrates through the positioning plate 2. In this way, during use, the positioning plate 2 can slide smoothly with high precision to ensure the perpendicularity of the positioning plate 2 during sliding.
[0041] Further, as Figure 1 、 Figures 3 to 5 and Figure 7As shown, the number of the first grooves 51 is multiple, and the multiple first grooves 51 are arranged side by side at equal intervals. The number of the second grooves 21 is equal to that of the first grooves 51, and the positions of the second grooves 21 correspond to those of the first grooves 51 one by one. Specifically, the pressing plate 1 and the positioning plate 2 are arranged in parallel. In this way, when in use, multiple specimens can be prepared simultaneously, thereby improving the preparation efficiency of the specimens.
[0042] Further, the bottom end of the guiding rod 12 is in threaded connection with the bottom surface of the groove structure 41. Specifically, an external thread is provided on the outer surface of the bottom end of the guiding rod 12, and a threaded hole is vertically provided on the bottom surface of the groove structure 41. In this way, it is convenient to disassemble and assemble the guiding rod 12 on the bottom surface of the groove structure 41.
[0043] Further, Teflon coating layers are coated on the outer surfaces of the bottom plate 4, the fixing plate 5, the positioning plate 2 and the pressing plate 1. In this way, when in use, it is convenient for reuse and specimen demolding.
